Technical Field

The invention relates to the technical field of fiber processing equipment, in particular to a track rolling type loose fiber washing machine.

Background

At present, in the loose fiber processing industry, there are two main types of equipment for dyeing and washing cellulose fibers such as cotton, viscose and the like, and the equipment is divided into an intermittent type hanging dyeing machine and a continuous type dyeing machine. The dyeing and water washing processes of the intermittent type hanging dyeing machine are carried out in the same equipment, and the treatment of the fiber has the defects of high energy consumption, high labor intensity and high sewage discharge. Compared with an intermittent suspension dyeing machine, the continuous dyeing machine achieves the purposes of energy conservation and emission reduction in dyeing, is immature in a water washing process, and mainly focuses on the aspects of the water washing effect, the water washing continuity and the energy consumption of drying after water washing.

The process comprises the steps of scouring, bleaching and dyeing loose fibers, scouring and bleaching, washing after dyeing, soaping, acid neutralization and the like of natural fibers such as cotton, wool, silk, hemp and the like, viscose, terylene, nylon, acrylic fibers and the like, wherein an intermittent production mode is mostly adopted, the equipment is generally an intermittent loose fiber dyeing machine, and dye liquor in the dyeing process flows and water flow in the washing process is forced to permeate through a fiber layer through a circulating pump. The method for forcing the liquid flow to pass through the fiber layer by the circulating pump is used for dyeing because of the requirement of level-dyeing property, but the washing efficiency is very low when the method is used for washing, because the loose fiber dyeing machine has no liquid removal function of a special washing machine (liquid removal can be carried out after liquid discharge of laundry in the washing machine), and has no roll extrusion and counter-current water supply effects of a special efficient continuous washing machine, and the roll extrusion and the counter-current water supply are basic measures for saving water, electricity and steam, reducing labor intensity and reducing manpower when the fabric is continuously washed by water, but the loose fiber state is different from the fabric state of the textile, and the continuous washing and soaping process is realized, and the technical difficulty is great in equipment aspect.

Disclosure of Invention

The invention discloses a track rolling type loose fiber washing machine, which aims to solve the technical problems that loose fibers are difficult to wash continuously and the water, water and gas consumption is high.

In order to achieve the purpose, the invention adopts the following technical scheme:

a caterpillar rolling type loose fiber washing machine comprises a fiber bearing caterpillar and a plurality of groups of caterpillar rolling devices, wherein the caterpillar rolling devices are uniformly distributed right above the fiber bearing caterpillar at intervals, and an extrusion space of a fiber layer is enclosed between the caterpillar rolling devices and the fiber bearing caterpillar; the inner side of the fiber bearing crawler belt is also provided with a plurality of pressure-bearing guide rollers, and the pressure-bearing guide rollers and the crawler belt rolling device are arranged in opposite directions; two sets of it is adjacent all be provided with the shower between the track rolling machine, all be provided with down the shower between two adjacent pressure-bearing deflector rolls, just go up shower, the relative direction setting of shower down.

As a further preferred aspect of the present invention, each set of track rolling devices includes a first rolling guide roller, a second rolling guide roller, a third rolling guide roller and a fourth rolling guide roller connected to each other through a rolling track, the first rolling guide roller and the second rolling guide roller are arranged in parallel, the third rolling guide roller and the fourth rolling guide roller are arranged in parallel, the first rolling guide roller and the second rolling guide roller are arranged above the third rolling guide roller and the fourth rolling guide roller, and a distance between the first rolling guide roller and the second rolling guide roller is greater than a distance between the third rolling guide roller and the fourth rolling guide roller.

Preferably, the included angle formed by the central connecting axis of the first rolling guide roller and the third rolling guide roller and the horizontal direction is 20-45 degrees, and the fiber layer sequentially enters the extrusion space between the crawler rolling device and the fiber bearing crawler to be extruded and scattered.

Preferably, an included angle formed by a connecting line of central axes of the second rolling guide roller and the fourth rolling guide roller and the horizontal direction ranges from 60 degrees to 85 degrees, and the upper spray pipe on the front side sprays water flow to prevent loose fibers from being adhered to the surface of the rolling track.

As a further preferred aspect of the present invention, a pressing device is further installed on the second rolling guide roller for adjusting the pressure of the second rolling guide roller.

As a further preferred aspect of the present invention, each of the upper and lower shower pipes supplies water through the same water tank, a plurality of water tanks are arranged side by side at the bottom or the side of the washing machine, and each water tank is provided with a direct steam heating system.

As a further preferred aspect of the present invention, the pipeline connecting the upper and lower showering pipes to the water tank is further provided with a filter and a circulating pump, and water filtered by the filter is pumped into the upper and lower showering pipes through the circulating pump for spraying and washing.

In a further preferred embodiment of the present invention, the water washing machine is configured such that the water tank is supplied with water by supplying water in a reverse flow manner, in which the direction of the water supply from the water tank is opposite to the running direction of the fiber carrying crawler.

The invention creatively provides a method for continuous operation of loose fibers, namely, carrying the fibers by a crawler belt, and realizes continuous and efficient water washing which is the same as the processing of textile cloth. The loose fiber cannot be continuously operated just like textile cloth easily through simple mechanical traction because of the state of the loose fiber, which is the main reason that the processes of dyeing, scouring and bleaching, water washing and the like of various fibers in the past and the current industry always adopt an intermittent production mode, and the used equipment is a loose fiber dyeing machine for intermittent production. The disadvantages of dyeing and washing processes with loose fiber dyeing machines include poor product processing quality stability, high water, electricity and steam consumption, high labor intensity, high labor consumption, high chemical consumption, etc. The invention firstly creatively provides that the continuous operation of loose fibers is carried out in a way of carrying the fibers by a track, which is a key step for realizing the continuous and efficient water washing process of the loose fibers and the like.

In addition, the invention also adopts measures such as track rolling, spray pipe spraying, countercurrent water supply and the like, which is an effective measure for realizing high efficiency, energy conservation and emission reduction in the processes of continuous washing of the loose fibers and the like.

The crawler rolling is a method which is suitable for bulk fiber processing and can realize the same effect as roll extrusion in the continuous washing process of textile cloth and the like according to the state of the bulk fiber. The roller extrusion is a step of reducing the 'residual liquid rate' in the cloth as much as possible when the cloth is switched from the previous washing to the next washing, wherein the 'residual liquid rate' can be reduced to about 80% or lower, which is equivalent to a 'dehydration' step to be carried out when water is changed every time when the clothes are washed by a roller washing machine, if the 'extrusion' or the 'dehydration' is not carried out, the residual liquid rate can reach about 300% or higher, and the 'washing efficiency with extrusion' is more than three times that of the 'washing without extrusion'. The 'extrusion' of the cloth can be directly extruded by a roller (such as a pair of straight rollers), but when the roller extrusion is used for stacking layers of loose fibers, the fiber layers are scattered and disordered, even the phenomenon that fiber felts are wound on the roller is caused, so that the continuous process cannot be smoothly carried out. The invention creatively provides an extrusion method of 'track rolling', which can ensure the smooth operation of the process.

In the past and the current industry, loose fiber washing methods are generally used for washing by a loose fiber dyeing machine in an intermittent production mode, the ' residual liquid rate ' of the loose fiber washing method is about 300 percent or higher during each water change, compared with the continuous washing method of the invention which realizes the ultralow ' residual liquid rate ' (about 80 percent or lower) through ' crawler rolling, the water consumption is increased by 2.5 times or even higher, and in addition, the water change of each time of the intermittent washing method not only discharges water, but also discharges heat and excessive effective chemicals, particularly high-temperature hot water washing (such as boiling at more than 95 ℃) and chemical treatment (such as soap acid neutralization, color fixation, softening, antistatic treatment and the like).

The "shower spraying" is performed by performing bidirectional spraying through an "upper shower" and a "lower shower" disposed above and below the fiber stacking layer. The spraying function of the upper spraying pipe is to realize the basic collision and exchange between liquid (water washing liquid, acid neutralization liquid, chemical liquid and the like) and fiber so as to realize the cleaning effect; the spraying effect of the lower spraying pipe is three, firstly, the same cleaning effect as that of the upper spraying pipe is realized, secondly, the fiber layer structure after being rolled by the crawler belt is loosened, the spraying and washing effect is improved, thirdly, the collision and exchange strength between liquid (water washing liquid, acid neutralizing liquid, chemical liquid and the like) and fibers can be increased through the upper and lower same-phase opposite spraying.

"counter-current water supply" means that the direction of the washed objects (such as fabrics, yarns and loose fibers) running under the action of machinery (the invention is the caterpillar band-carried fibers) is opposite to the flow direction of the washing water, and more importantly, the water is only continuously supplemented with clean water in the last washing liquid in the running route of the washed objects (the invention is the loose fibers), and the supplemented water flows lattice by lattice along the direction opposite to the running direction of the washed objects, namely, the first washing is the dirtiest water, the last washing is the cleanest water, and the counter-current water supply is a basic measure for improving the efficiency of continuous washing, reducing the consumption of water and electricity and steam and reducing the consumption of chemicals, and is an important measure.

The crawler belt rolling device has the beneficial effects that the crawler belt rolling device is simple in structure and novel in design, the length and the size of a rolling crawler belt in the crawler belt rolling device are adjustable, the diameters of the first rolling guide roller, the second rolling guide roller, the third rolling guide roller and the fourth rolling guide roller can be adjusted according to actual production requirements, and the crawler belt rolling device is wider in applicability; the invention introduces the continuous washing method and technology for the fabric into the processing of loose fibers, greatly reduces the consumption of water, electricity and steam, reduces the labor and labor intensity and reduces the consumption of chemicals.
