Technical Field

The invention relates to a filter cloth cleaning device, in particular to a high-power ultrasonic-assisted acid and alkaline cleaning device for used filter cloth.

Background

At present, the textile fiber woven filter cloth for industry is widely applied to the filtration processes of mineral resource industry such as mineral separation dehydration, coal washing, petroleum dewaxing of an oil refinery, liquid/solid separation of industrial fluid, and material purification or recovery. In the manufacturing process and the technology of the woven filter cloth, a warp and weft interlacing weaving mode is adopted, and the control of the filtration porosity, namely the filtration efficiency, is realized by the fineness of the warp and the weft and the interlacing density and the interlacing mode of the warp and the weft; moreover, the interweaving or the interlacing of the warp yarns and the weft yarns forms interweaving points or gaps which are distributed uniformly and comprehensively on the surface of the filter cloth, so that particles of a filtered object are easy to gradually gather and accumulate at the interweaving points or the gaps in the frequent filtering operation process, the filtering pores are reduced, cakes are not easy to detach, the filter cloth is blocked, the pump pressure of a filter liquid input system is increased, the filtering efficiency is reduced, the replacement period of the filter cloth is shortened, the service life of the filter cloth is shortened, and the production efficiency of a filter cloth user is reduced and the production cost is increased. Among them, the clogging and difficulty in cleaning of the filter cloth are one of the main causes of the reduction of the filtering efficiency of the filter cloth and the waste of the filter cloth. It has been a common practice in the industry to place the filter cloth to be replaced in a cleaning tank containing a cleaning solution for soaking, wherein the filter cloth containing the basic filter medium is soaked with an acidic cleaning solution, and the filter cloth containing the acidic filter medium is soaked with an alkaline cleaning solution. After long-time soaking, manually turning over the cloth in the soaking tank by using a wooden stick and other similar tools to promote the impurities in the pores of the filter cloth to fall off, then discharging the pickling liquid or the alkaline washing liquid in the soaking tank, and then injecting clear water for cleaning. And naturally airing the cleaned filter cloth or drying the filter cloth and then putting the filter cloth into reuse. However, the conventional cleaning method is long in time consumption, labor intensity of manual overturning and cleaning is high, the filter cloth is large in size, heavy in weight and not easy to overturn after being soaked in water, and cleaning effect is uneven and cleaning is not thorough due to the reasons. So that some filter cloth users do not want to clean and directly discard and renew the used filter cloth. And a better solution is still not provided in the filter cloth cleaning and recycling links of textile fiber filter cloth users so far.

Detailed Description

The following examples of the present invention are described in detail, and are only for the purpose of illustrating the present invention and are not to be construed as limiting the present invention.

The used longitude and latitude raw materials of the filter cloth to be cleaned adopted in the embodiment are all chemical fibers, and the fiber types are as follows: polyamide fibers; the longitude and latitude fineness is 120D; monofilament form; the texture is 1/1 plain weave; and (3) warp and weft density: size of 220/10 cm. filter cloth: 180cm X180 cm. The pH value of the filter medium on the filter cloth is as follows: weakly acidic.

The specific process flow of the embodiment is as follows: the filter cloth which is arranged on the plate-and-frame filter press and reaches the machine to be discharged in the service cycle is cleaned by the cleaning device.

Assembling: the filter cloth which is on a plate-and-frame filter press and is discharged in the service cycle is loaded on a filter cloth hanging rod shown as 10 in the attached drawing, then the filter cloth hanging rod 10 on which a plurality of pieces of filter cloth 6 and 14 to be cleaned are hung is integrally arranged on a filter cloth hanging rod support 9 in a cleaning device, then weak alkaline soak solution is input into the cleaning device through a soak solution input pipeline 7, the liquid level of the soak solution is enabled to be submerged in the filter cloth 6 and 14 to be cleaned, and then soaking is kept for a period of time. The length of the soaking period depends on the pH value of the soaking liquid 8 in the cleaning device. Generally, when the pH value of the soaking liquid 8 in the cleaning device reaches neutral, the ultrasonic device is started to perform ultrasonic vibration cleaning after the soaking liquid is kept for 1-2 hours. 3 and 7 are soaking solution and an input pipeline thereof, 4 is a soaking solution discharge pipeline, 6 and 14 are filter cloth in cleaning, 10 is a filter cloth hanging rod, 9 is a filter cloth hanging rod support, 11 and 12 are filter cloth hanging rollers and supports thereof on the filter cloth hanging rod, 8 is acid or alkaline or neutral cleaning liquid, 17 is an ultrasonic generator, 2 is an ultrasonic transducer, 16 is an ultrasonic vibration plate, 18 is an ultrasonic generator power supply device, 5 is high-power ultrasonic wave beams, and 13 and 15 are bubbles generated during high-power ultrasonic vibration.

Starting the ultrasonic vibration cleaning device: the power supply 18 of the ultrasonic generator is switched on, the ultrasonic generator 17 and the ultrasonic transducer 2 are started, the ultrasonic vibration plate 16 starts to release the high-power ultrasonic beam 5 into the cleaning tank, and at the moment, under the vibration action of the high-power ultrasonic beam 5, a large amount of bubbles 13 and 15 are generated in the cleaning liquid in the cleaning tank. The bubbles 13 and 15 and the ultrasonic beam 5 generated by these vibrations accelerate the detachment of the filter medium remaining on the filter cloth from the filter cloth. The duration of the ultrasonic treatment depends on the state that the filter medium remaining on the filter cloth is separated from the filter cloth. The time length in this embodiment is 1 h. Wherein: the ultrasonic power was 500W, the additional frequency was 20kHz, and the area of the ultrasonic radiation vibrating plate was 200cm X100 cm.

Starting a cleaning program: after the alkali washing and the ultrasonic treatment are finished, the soak solution in the cleaning device is discharged completely through a soak solution discharge pipeline 4. Then, clean water is injected into the cleaning device through the soaking liquid input pipeline 7, and the liquid level of the soaking liquid is enabled to be submerged through the filter cloths 6 and 14 to be cleaned. Then, the ultrasonic vibration cleaning apparatus is started again: the power supply 18 of the ultrasonic generator is switched on, the ultrasonic generator 17 and the ultrasonic transducer 2 are started, the ultrasonic vibration plate 16 starts to release the high-power ultrasonic beam 5 into the cleaning tank, and at the moment, under the vibration action of the high-power ultrasonic beam 5, a large amount of bubbles 13 and 15 are generated in the cleaning liquid in the cleaning tank. The bubbles 13 and 15 and the ultrasonic beam 5 generated by these vibrations accelerate the detachment of the filter medium remaining on the filter cloth from the filter cloth. The time length in this embodiment is 1 h.

After the cleaning in the cleaning tank is completed, the filter cloth hanging rod 10 on which the plurality of pieces of cleaned filter cloths 6 and 14 are hung is lifted out of the cleaning device as a whole and placed on a support in a cleaning place to naturally control water and dry, and then the cleaning work is completed.

After the implementation of the invention is finished, the production operation test and detection of the filtration production user are carried out, and the expected good effect is obtained.
