Technical Field

The invention relates to the technical field of open-width wet treatment equipment for woven fabrics, in particular to the improvement of a structure of a water washing tank of the open-width wet treatment equipment.

Background

In the prior art, the open-width wet treatment equipment for the woven fabrics uses a traditional upper guide roller washing tank and a traditional lower guide roller washing tank as main washing units, and although configurations such as high vehicle speed, low tension, strong spraying and the like are developed, the overall design is not changed greatly in decades.

At present, washing equipment on the market has various cleaning and cleaning modes, and the mode without water is not mentioned. As a water washing unit which is simultaneously provided with a rotary drum rotor mechanism and a guide roller, the water washing is mainly performed under the condition of 'water'. Effective water washing is not achieved when the fabric has insufficient moisture/water content without being sufficiently soaked. The water content is calculated according to a water content calculation mode given by QB/T2330-2017 industrial dryer:

＝

(ii) a Representing the quality of the dried fabric; g; indicates the quality of the completely dried fabric;

different water absorption also results in different water content/water content due to different fabric materials. Taking this as an entry point, we can begin to analyze specific factors affecting the water washing effect.

Five major factors influencing the washing effect:

1) realizing the washing effect of the fabric through water/water exchange; if water is added/supplemented, clear water and dirty water flow/exchange with each other, and impurities are discharged from the fabric through water exchange; the clean water refers to soft water, namely the content of magnesium carbonate/calcium in each liter of water is less than 6 hardness, 1 hardness is equivalent to 10 mg of magnesium carbonate/calcium in each liter of water, and the mg of magnesium carbonate/liter of water is usually expressed by ppm.

2) The washing effect of fabric decontamination is realized through the relative movement between water and the fabric; the method specifically comprises the following steps:

2.1. strongly washing the surface of the fabric by using high-pressure spraying;

2.2. strong penetration of the fabric by the vortex created by the forced convection created by the relative motion of the rotor/drum;

2.3. the upper/lower guide rollers are used for washing the fabric, and water flows from top to bottom on the surface of the fabric.

3) Extruding; i.e. by mechanical forces to achieve a detergent washing effect. If the squeezing of the roller of the padder to the fabric and the squeezing effect of the tension between the fabric and the guide roller during the washing of the upper/lower guide roller are utilized, dirty water in the fiber and between the fibers is forced out of the surface of the fiber and is subjected to water exchange with clean water in the washing element 1), and impurities are discharged from the fabric through the water exchange.

The water washing element 3) of the upper/lower guide roller water washing unit of the conventional design is pressed by mechanical force to achieve the decontamination water washing effect. The fabric is squeezed after being washed in each washing unit and before being transferred to the next washing unit. The squeezing mode of the general conventional upper/lower guide roller water washing unit is mainly realized by two ways: one is by padder (but sometimes other means such as vacuum squeezing of water may be used depending on the process requirements); and secondly, squeezing is carried out by pressure points between the fabric and the guide rollers when the upper/lower guide rollers in the traditional upper/lower guide roller washing unit are washed.

4) A chemical auxiliary agent; the washing efficiency is improved by chemical reaction; another use is to provide the desired chemical reactions of the fabric such as: mercerizing, bleaching, etc.

5) And temperature; the temperature is helpful for improving the heat energy during washing, the dissolution of the auxiliary agent or the detergent can be accelerated along with the increase of the temperature, the movement of active molecules is accelerated, the active molecules can quickly permeate into the fabric, the dirt-removing capacity is stronger, and the washing efficiency is improved; such as: and (5) steaming.

In addition, the washing procedure can also affect the washing effect. For example, the process flows of desizing, scouring, reduction soaping and the like can select different washing procedures for different fabric types, stain characteristics and stain degrees so as to achieve ideal washing effect.

The washing element 2) in the upper/lower guide roller washing unit in the traditional design is mainly that water flows from top to bottom on the surface of the fabric when the fabric shuttles between the upper/lower guide rollers; taking figure 1 as an example, the fabric shuttles in an upper/lower guide roll washing unit and the warp direction length of the fabric of the washing element 2) is 4.09 meters.

Taking fig. 1 as an example, although the fabric volume in the upper/lower guide roller washing unit of the conventional design is 16 meters, in an actual production situation, the fabric generally passes through the padder of the front-stage washing unit before the upper/lower guide roller washing unit in the middle section of the long car, the moisture content/water content of the fabric is generally about 70%, when the fabric with the moisture content/water content of 70% enters the first unit of the washing unit, the fabric must enter the liquid level L first to contact the lower guide roller r1 under the liquid to start liquid suction, when the fabric leaves the lower guide roller r1 and leaves the water level, the moisture content/water content of the fabric cannot satisfy the implementation of the washing element 2), and cannot satisfy the implementation of the washing element 3) when the upper guide roller s1 is located above, the fabric must enter the liquid level L again to contact the lower guide roller r2 under the liquid to absorb the liquid again, when the fabric leaves the lower guide roller r2 and leaves the water level, the water content/water content can meet the implementation condition of the 2.3 < 2 > effective washing of the flowing water from top to bottom on the surface of the fabric during the washing of the upper/lower guide rollers in the washing element 2), and the washing is started in the washing unit at the first time. Then, when the fabric runs to the upper row of rollers s2, the fabric surface coated on the rollers is under the action of the radial tension of the rollers, so that the water washing element 3) is implemented; the fibers in the fabric and the water among the fibers are extruded out of the surface of the fibers and are subjected to water exchange with clean water in a water washing element 1), impurities are discharged from the fabric through water exchange, and the situation is continued to the lower guide roller r6 after the lower guide roller r 2.

The above statements explain why the "effective wash length" in the first and second wash units in fig. 1 is equal to v2+ v3+ v4+ v5 + v6 = 4.09 meters. Before the fabric leaves the upper/lower guide roller washing unit, the fabric passes through a padder, and the moisture content/water content of the fabric returns to about 70% again, so that the fabric is prepared for the next washing process. Thus, when two identical water wash units are connected together, the "effective water wash length" is only 8.18 meters.

When the washing unit is placed in the first box of a long car or the first box after the steaming box, as shown in fig. 2, the water content/water content before the fabric enters the unit is from 8% (dry fabric) or about 60% (after steaming), if the dry fabric enters the unit, the effective washing length of the first washing unit is only v5 + v6 = 1.34 m, mainly because the fabric containing amount of the first five pairs of upper/lower guide rolls of the washing unit is consumed on the wet fabric, and the sum of the effective washing lengths of the second washing unit in fig. 2, v8 + v9 + v10 + v11 + v12 = 4.09 m, is only 5.43 m.

In conclusion, the existing washing units have low overall washing efficiency, the number of the washing units of the whole open-width wet treatment equipment is large, and the whole open-width wet treatment equipment is long and occupies a large area.

Detailed Description

The structure of the present invention will be further described with reference to the accompanying drawings and preferred embodiments of the present invention.

Referring to fig. 3, the water washing unit provided with a rotary drum rotor mechanism and guide rollers at the same time of the present invention comprises a box body, a fabric guide roller a1 is arranged in the box body, and a first lower roller R1 corresponding to the fabric guide roller a1 is arranged below a liquid level L in the box body; a first rotor drum driving mechanism D1 corresponding to the first lower roller R1 is provided below the liquid level L in the tank.

The first rotor drum driving mechanism D1 is composed of a driving drum and a driving rotor arranged in the driving drum, paddle blades are arranged on the driving rotor, the rotating speed of the driving rotor is greater than that of the driving drum, so that working liquid on the inner side of the driving drum is guided to the central direction of the driving rotor and then is discharged from two sides in the rotating process of the driving rotor according to the Bernoulli principle, the pressure on the inner side of the driving drum is lower than that of the outer side, the working liquid on the outer side surface can enter the inner side through a through hole in the driving drum, and the fabric coated outside the driving drum is better attached to the surface of the driving drum under the action of a suction effect, so that the friction between the fabric soaked under the liquid and the driving drum is increased, the fabric washing condition is stable, and a lower fabric conveying tension and a more fabric washing flow can be obtained; the main function of the first rotor drum driving mechanism D1 used in the present invention is to increase the water absorption capacity of the fabric, and to absorb more water than the conventional roller, which is beneficial to the water washing effect and the implementation of the subsequent water washing factor 2).

An upper guide roller set and a lower guide roller set corresponding to the first rotor drum driving mechanism D1 are further arranged in the box body; the upper and lower guide roller sets comprise a lower row of rollers and an upper row of rollers arranged above the lower row of rollers; the lower row of rollers is arranged below the liquid level, and the upper row of rollers is arranged above the liquid level. In this embodiment, the lower row of rollers is composed of 5 lower rollers side by side, i.e., a second lower roller R2, a third lower roller R3, a fourth lower roller R4, a fifth lower roller R5 and a sixth lower roller R6; the upper row of rollers consists of 4 upper rollers which are arranged side by side, namely a first upper roller S1, a second upper roller S2, a third upper roller S3 and a fourth upper roller S4. The upper and lower guide roller sets are equivalent to the 2.3 < 2 > item of the water washing element 2) that the water flows from top to bottom on the surface of the fabric during the water washing of the upper/lower guide rollers.

In order to ensure that the fabric can be more coated on the upper-row roller when running to the upper-row roller, the surface of the fabric is under the action of the radial tension of the roller, and the water washing element 3) is promoted to be implemented; fibers in the fabric and water among the fibers are extruded out of the surface of the fibers and are subjected to water exchange with clear water by a washing element 1), and a middle-discharge guide roller for coating the fabric on the lower surface of an upper roller is arranged below each upper roller; that is, a first middle guide roller B1, a second middle guide roller B2, a third middle guide roller B3 and a fourth middle guide roller B4 are respectively corresponding to the lower portions of the first upper roller S1, the second upper roller S2, the third upper roller S3 and the fourth upper roller S4.

In order to enhance the squeezing effect of the fibers in the fabric passing through the upper row of rollers and the moisture among the fibers, at least one upper roller in the upper row of rollers is provided with a primary roller. In this embodiment, the first upper roll S1 and the third upper roll S3 are provided with a first primary roll C1 and a second primary roll C2, respectively, which are equivalent to small rolls for squeezing, and water is pushed out of the surface of the textile fiber and is subjected to water exchange with the rinsing element 1) with clean water.

In order to increase the effective washing length in a limited space, the box body is internally provided with a spraying device for spraying, washing and washing the fabrics passing through the upper and lower guide roller sets. In the embodiment, a first spray head E1, a second spray head E2 and a third spray head E3 are respectively arranged at the rear sides of the first upper roller S1, the third upper roller S3 and the fourth upper roller S4.

A second rotor drum driving mechanism D2 corresponding to the upper and lower guide roller sets is arranged below the liquid level L in the box body, and a padder mechanism 2 for extruding and discharging the fabric washed by the second rotor drum driving mechanism is arranged above the liquid level in the box body. The second rotor drum driving mechanism D2 has the same principle as the first rotor drum driving mechanism D1, and both are for fully sucking moisture; in order to fully exert the effect of the second rotor drum driving mechanism D2, a lower guide roller R7 for coating the fabric on the upper surface of the second rotor drum driving mechanism D2 is further provided between the second rotor drum driving mechanism D2 and the padder mechanism 2, and the fabric is coated on the second rotor drum driving mechanism D2 to the maximum extent under the action of the lower guide roller R7. In order to further improve the liquid suction effect of the fabric, the lateral sides of the first rotor drum driving mechanism D1 and the second rotor drum driving mechanism D2 are provided with submerged spray heads.

The padder mechanism 2 has the same structure as the traditional structure, and performs squeezing of the washing element 3), and the fabric decontamination effect is realized through mechanical force, according to the conclusion obtained by comparing the washing element 2 of the upper/lower guide roller washing unit in the traditional design, under the condition that the effective washing length of the washing unit is the same, a group of padders are omitted in the design of the washing element 3) as a washing unit which is simultaneously provided with a rotary drum rotor mechanism and guide rollers. However, the first upper roller S1 and the third upper roller S3 are respectively provided with the first primary roller C1 and the second primary roller C2 for compensation, and the large wrap angle of the first upper roller and the second upper roller is added with the use of the middle row of guide rollers, so that the extrusion amount is improved, the two additional configurations improve the efficiency of the water exchange capacity of dirty water between fibers to be forced to the surface of the fabric and clean water as an element 1), and the comprehensive efficiency replaces the missing set of padders.

The invention is a new invention design of a water washing unit which is simultaneously provided with a rotary drum rotor mechanism and a guide roller, integrates a plurality of different 'water washing elements' in the same unit, and is matched with a new water washing process, so that the most efficient water washing process can be achieved in the unit no matter whether the fabric is woven or knitted, the whole water washing efficiency of the water washing unit is improved, the number of the water washing units of the whole equipment can be reduced, and the length of the whole machine can be effectively shortened.

And (3) comparing with the washing element 2 of the upper/lower guide roller washing unit in the traditional design): the invention realizes the washing effect of fabric decontamination by relative movement between water and fabric, and mainly combines the following three modes simultaneously: 1. strongly washing the surface of the fabric by using high-pressure spraying; 2. powerful penetration of the fabric by the vortex created by forced convection created by the relative motion of the rotor drum drive mechanism; 3. when the upper/lower guide rollers are used for washing, water flows from top to bottom on the surface of the fabric; similarly, the fabric volume is 16 meters, the fabric is immediately transferred to the submerged first rotor drum driving mechanism D1 after entering the liquid level and passing through the first lower roller R1, the liquid absorption is continued in the process, the liquid absorption length of R1 + R2 = 0.81 meter required in the original image 1 demonstration is achieved when the fabric passes through about one third of the surface of the first rotor drum driving mechanism D1, meanwhile, the fabric has the condition of executing the washing element 2) at the position of the submerged first rotor drum driving mechanism D1, the fabric formally starts to enter a washing flow, the fabric is washed in a flowing mode from top to bottom on the surface of the fabric when going through the vortex washing of the submerged first rotor drum driving mechanism D1, the submerged spray head, the continuous immersion washing of the second lower roller R2 and then leaves the water surface to carry out the 2.3 th of the washing element 2) when the fabric goes out of the water surface, the fabric when the upper guide roller group and the lower guide roller group is used for washing, the fabric goes to the first upper roller S1, the fabric surface covered on the first upper roller S1 is acted by the radial tension of the roller, and the first primary roller C1 is extruded, so that the water washing element 3) is implemented; the fibers in the fabric and the water among the fibers are extruded out of the surface of the fibers and are subjected to water exchange with clear water in a washing element 1), and impurities are discharged from the fabric through the water exchange.

Meanwhile, the application of a spraying device above the box body is added, so that the fabric is transferred from the first upper roller S1 to the lower cloth moving path W1 of the third lower roller R3, the lower cloth moving path W3 from the third upper roller S3 to the fifth lower roller R5 and the lower cloth moving path W4 from the fourth upper roller S4 to the sixth lower roller R6 are optimized to be the conditions for realizing the washing element 2); spraying water to the surface of the fabric in the downward movement from the spraying pipe, and taking the path which is not the effective washing length originally; also optimized as "effective wash length". After the fabric is washed by the series of upper/lower guide rollers with the rollers and the spraying to optimize the washing efficiency, the fabric enters the submerged second rotor drum driving mechanism D2 again for vortex washing, the fabric leaves the water surface again after the soaking washing, and the total effective washing length Z = (U1+ V1+ W1+ V2+ V3+ W3+ V4+ W4+ U2+ V5) = 8.18 meters; wherein U1 is the path from the start of the position where the fabric is conditioned on the surface of the first rotor drum drive D1 to leave the surface of the first rotor drum drive D1; v1 is the path from the second lower roller R2 to the first middle guide roller B1; v2 is the path from the third lower roller R3 to the second middle guide roller B2; v3 is a path from the fourth lower roller R4 to the third middle guide roller B3; v4 is a path between the fifth lower roller R5 and the fourth middle guide roller B4; u2 is the path of the web in contact with the surface of the second rotor drum drive mechanism D2; v5 is the path from the lower guide roll R7 to the guide roll S5 of the padder mechanism 2. Therefore, the effective water washing length and the effective water washing length of the two traditional upper/lower guide roller water washing units with 16-meter cloth capacity are equivalent to those of the 16-meter cloth capacity water washing unit, so that the length of the whole machine can be effectively shortened, and the floor area of equipment is reduced.
