Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment equipment, in particular to printing and dyeing desizing wastewater treatment equipment. Background Art

[0002] At present, the fabric printing and dyeing industry is developing faster and faster, and the competition is becoming more and more fierce. The printing and dyeing process of fabric determines the quality of the finished fabric. Therefore, the printing and dyeing process of fabric plays a vital role in the field of fabric production.

[0003] Traditional fabric printing and dyeing processes generally include singeing, desizing, scouring, printing and dyeing, etc. The fabric after the singeing process is sent to the next desizing process. Desizing mainly involves coating the warp yarn with sizing agent before spinning, thereby improving the strength and wear resistance of the warp yarn. However, these sizing agents will increase the consumption of dyeing chemicals during printing and dyeing, so desizing operations are required.

[0004] In the traditional desizing process, the fabric is immersed in water for repeated washing, which is inconvenient to operate and has low desizing efficiency. In the traditional scouring process, the fabric usually needs to be manually cleaned after scouring, which is labor-intensive and inefficient.

[0005] The concentration of pollutants in desizing wastewater is too high. It contains various sizing agents, sizing decomposition products, fiber scraps, starch alkali and various additives, making the wastewater alkaline. If it is discharged directly, it will have an adverse impact on the environment and people. However, there is no separate system on the market to treat wastewater containing PVA, and it is impossible to accurately determine whether the alkalinity of the wastewater meets the discharge standard. Therefore, it is necessary to develop a device that can improve the desizing effect and the wastewater treatment effect at the same time. Summary of the invention

[0035] Combined with Figure 2 When working, the cloth is put on the two handles 3, and the desizing liquid is poured into the box 1. Two workers stand on both sides of the box 1 and turn the handles 3 to tighten the cloth repeatedly to press out the chemical agent on the cloth. During the tightening process of the cloth, the handles 3 move closer to the middle.

[0036] The monitoring module 4 is composed of a main tank body 41 and a sub-tank body 42. An upper chamber 411 and a lower chamber 412 are provided in the main tank body 41.

A probe 417 is fixedly installed on the inner wall of the lower chamber 412. The probe 417 is aimed at the absorbent paper 7. An infusion component is also provided in the lower chamber 412. The infusion component is used to drip waste water on the absorbent paper 7. The above-mentioned probe 417 is similar to a camera.

[0037] The infusion assembly is composed of a straw 8 and a sliding sleeve 9. A clip 415 is welded on the top of the inner wall of the lower chamber 412. The clip 415 is used to clamp the absorbent paper 7. A micro water pump 85 is fixedly installed at one end of the straw 8, and the micro water pump 85 extends to the outside of the main tank 41. The other end of the straw 8 passes through the clip 415 and is aligned with the absorbent paper 7. The sliding sleeve 9 is sleeved outside the straw 8. A micro electric push rod 416 is fixedly installed on the inner wall of the lower chamber 412 and below the straw 8. The movable end of the micro electric push rod 416 is welded to the sliding sleeve 9. The micro electric push rod 416 is extended to push the sliding sleeve 9 to move. When the sliding sleeve 9 moves to the farthest, the waste water drips onto the absorbent paper 7 through the straw 8.
