Description

Technical Field

[0001] This utility model relates to the field of textile printing and dyeing technology, and in particular to a textile printing and dyeing water washing box. Background Technology

[0002] In the textile printing and dyeing industry, the washing process is a crucial step in ensuring the quality of printing and dyeing. Its core function is to remove residual dyes, auxiliaries, and impurities from the surface of the fabric, ensuring uniform color and a satisfactory hand feel. Currently, most mainstream textile printing and dyeing washing equipment adopts a water recycling design to achieve water conservation. This means that the wastewater after washing is collected, filtered, reheated, and reused for fabric cleaning, forming a washing-filtration-recycling operation mode.

[0003] However, existing circulating filtration systems in washing equipment have certain shortcomings in practical applications. During the washing process, surface fiber debris and lint (collectively referred to as lint) enter the circulating system along with the wastewater. Existing filtration devices mostly use fixed or low-speed rotating filter screens, which easily adhere to the filter screen surface and become embedded in the filter pores, and lack an efficient active cleaning mechanism. As the operating time increases, the degree of filter screen clogging gradually worsens. On the one hand, this leads to a decrease in filtration flow rate, which cannot meet the circulating water requirements of the washing process, forcing the equipment to operate at a reduced load. On the other hand, it causes a decrease in filtration accuracy, allowing fine lint that is not completely intercepted to re-enter the washing water, adhere to the fabric surface, and form lint defects, seriously affecting the quality of printed and dyed products.

[0004] Therefore, it is necessary to provide a water washing box for textile printing and dyeing to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a washing box for textile printing and dyeing, which solves the problems mentioned in the background art.

[0006] To solve the above technical problems, this utility model provides a washing tank for textile printing and dyeing, including: a box body and a filter chamber. The filter chamber is fixedly installed on the outside of the box body. A filter screen is rotatably assembled inside the filter chamber. The filter screen can rotate relative to the filter chamber to filter the washing water. The filter screen divides the filter chamber into a filter chamber and a filter completed chamber. The filtration chamber is equipped with a backwash pipe that can spray clean water to backwash the slag on the filter screen. The filter chamber is fixedly connected to a slag plate to receive the backwashed slag wastewater. The filter chamber is equipped with a slag hopper to collect the slag in the slag wastewater and prevent it from entering the sewage system.

[0007] Preferably, the bottom of the box is provided with a drain pipe, and two jet channels and an overflow channel are also provided on the inner wall of the bottom of the box.

[0008] Preferably, a motor is fixedly installed on the filter chamber, and the filter screen is fixedly connected to the drive shaft of the motor.

[0009] Preferably, a transition pipe is provided between the housing and the filter assembly, and the two ends of the transition pipe are respectively connected to the overflow trough and the chamber to be filtered.

[0010] Preferably, a circulation pump is fixedly installed on the outside of the filter chamber, and the circulation pump is connected to the filter completion chamber.

[0011] Preferably, a spray pipe is provided at the upper part of the box body, and two spray pipes are provided at the lower part of the box body, with the two spray pipes located in two spray channels respectively.

[0012] Preferably, the box body is provided with a roller group, which includes a large net roller, a tension roller, a small net roller and an expansion roller. The large net roller, tension roller, small net roller and expansion roller are all rotatably installed inside the box body, with the large net roller located at the top. Two small net rollers are provided and located in the jetting groove. The tension roller and the expansion roller are located between the large net roller and the small net roller.

[0013] Preferably, the inside of the housing is provided with woven fabric, which is wrapped around the outside of the large web roller, tension roller, small web roller and widening roller, so as to facilitate the washing of the woven fabric by the spray pipe and the jet pipe.

[0014] Compared with related technologies, the textile printing and dyeing water washing box provided by this utility model has the following beneficial effects: 1. By installing a backwash pipe to clean the filter screen, the sludge adhering to the filter screen can be cleaned in real time or periodically during the continuous operation of water circulation filtration, thus avoiding the problem of filter hole blockage caused by sludge accumulation from the source.

[0015] Second, by setting up a slag hopper, the slag that is flushed down can be collected, preventing the slag from entering the sewage system and clogging the sewage pipes. Moreover, the cleaning and collection of slag can be completed without stopping the machine, which completely changes the traditional manual disassembly and washing of filter screens, which interrupts production and is time-consuming and labor-intensive, thus improving production efficiency.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Please refer to the following: Figs. 1 to 4 A washing tank for textile printing and dyeing includes: a tank body 10, a filter assembly 20, a transition pipe 22, a heat exchanger 30, a spray main pipe 40, a roller assembly 50, and a woven fabric 60. The filter assembly 20 is disposed on one side of the tank body 10, the transition pipe 22 is disposed between the tank body 10 and the filter assembly 20, the heat exchanger 30 is disposed at the outlet end of the filter assembly 20, the spray main pipe 40 is disposed at the outlet end of the heat exchanger 30, the roller assembly 50 is disposed inside the tank body 10, and the woven fabric 60 is wound around the roller assembly 50. The washing water is heated by the heat exchanger 30 and then enters the spray main pipe 40 to wash the woven fabric 60 wound around the roller assembly 50. The washed water passes through the transition pipe 22 to the filter assembly 20 for filtration, and after filtration, it re-enters the heat exchanger 30, thus recycling the washing water.

[0020] The bottom of the tank 10 is provided with a drain pipe 11. After the cleaning water inside the tank 10 is recycled multiple times, it can be discharged through the drain pipe 11. Two spray channels 101 and an overflow channel 102 are also provided on the bottom inner wall of the tank 10. The overflow channel 102 is connected to the transition pipe 22. The cleaned water will flow into the overflow channel 102 and then flow into the filter assembly 20 through the transition pipe 22.

[0021] The filter assembly 20 includes a filter chamber 201, a motor 202, a filter screen 203, a backwash pipe 204, a slag plate 205, and a slag hopper 206. The filter chamber 201 is fixedly installed on one side of the housing 10. The motor 202 is fixedly installed on the filter chamber 201. The filter screen 203 is fixedly connected to the drive shaft of the motor 202 and is located inside the filter chamber 201. The filter screen 203 divides the filter chamber 201 into two chambers: one for filtering and the other for filtering completion. The backwash pipe 204 is located on the upper part of the end face of the filter screen 203 and is located inside the filtering completion chamber. 205 is fixedly installed inside the filter chamber and located on the upper part of the end face of the filter screen 203. The lint hopper 206 is set outside the filter chamber 201. When the filter assembly 20 filters the circulating water, the motor 202 drives the filter screen 203 to rotate. The filter screen 203 filters the circulating water and leaves the lint in the fabric 60 on the filter screen 203. The backwash pipe 204 can spray clean water to backwash the lint stuck on the filter screen 203 onto the lint plate 205. The lint wastewater flows through the lint plate 205 to the lint hopper 206 to collect the lint. It is cleaned regularly by workers. The water flows to the outside of the device and is discharged to the sewage treatment device.

[0022] A circulation pump 21 is fixedly installed on the outside of the filter chamber 201. The circulation pump 21 provides the flow power for the cleaning water. The circulation pump 21 is connected to the filter completion chamber, and the transition pipe 22 is connected to the filter chamber.

[0023] The main spray pipe 40 is equipped with a spray pipe 41 and a jet pipe 42. The spray pipe 41 is located in the upper part of the box 10, and the jet pipe 42 is located in the lower part of the box 10 and is located in the jet trough 101. The spray pipe 41 sprays water from above the fabric 60, and its main function is to directly rinse the dyeing residue on the surface of the fabric 60. At the same time, it uses the impact force of the water flow from top to bottom to remove the floating color and fine impurities on the surface of the fabric 60. The jet pipe 42 sprays water upward from below the fabric 60, which can rinse the residual pollutants on the lower surface of the fabric 60. Together with the spray pipe 41, they form a top-and-bottom clamping cleaning effect to ensure that both sides of the fabric 60 are thoroughly cleaned.

[0024] The roller assembly 50 includes a large web roller 501, a tension roller 502, a small web roller 503, and a spreading roller 504. The large web roller 501, tension roller 502, small web roller 503, and spreading roller 504 are all rotatably mounted inside the housing 10, with the large web roller 501 located at the top. Two small web rollers 503 are located within the spray trough 101. The tension roller 502 and spreading roller 504 are located between the large web roller 501 and the small web roller 503. The spun fabric 60 passes above the spreading roller 504, below the first small web roller 503, above the large web roller 501, below the second small web roller 503, and above the tension roller 502 before being transported to the outside of the device. The large web roller 501, in conjunction with the spray pipe 41 above it, causes the spun fabric 60 to... Supported by the large web roller 501, the fabric 60 is kept flat and stretched, ensuring that the cleaning water sprayed from the spray pipe 41 from top to bottom can evenly cover the upper surface of the fabric 60, thoroughly rinsing away printing and dyeing residues and floating color. The tension roller 502 can adjust and maintain the constant tension of the fabric 60 during the washing process, ensuring the continuous and stable conveying of the fabric 60. The small web roller 503 supports the fabric 60 to maintain a horizontal or slightly stretched state, so that the cleaning water sprayed upward from the spray pipe 42 can accurately impact the lower surface of the fabric 60, rinsing away residual contaminants on the lower surface. The widening roller 504 can stretch and flatten the fabric 60 in the width direction before it enters the core washing area, correcting the width shape of the fabric 60 and avoiding insufficient cleaning in some areas due to wrinkles.

[0025] The working principle of the textile printing and dyeing water washing box provided by this utility model is as follows: External water source or water after circulation filtration first enters heat exchanger 30. Through heat exchange, the water temperature is raised to a temperature suitable for textile printing and dyeing cleaning. The heated cleaning water is transported to spray main pipe 40. The water is then diverted from spray main pipe 40 to spray pipe 41 and spray pipe 42 to prepare for subsequent double-sided cleaning. The spun fabric 60 runs along a preset path on the roller assembly 50 inside the housing 10. First, it passes above the spreading roller 504. The spreading roller 504, through its stretching action in the width direction, corrects any wrinkles that may exist in the spun fabric 60, ensuring that the spun fabric 60 enters the cleaning area with a complete and flat surface, avoiding insufficient cleaning in certain areas. The spun fabric 60 then enters below the small mesh roller 503 from the spreading roller 504. The small mesh roller 503 supports the spun fabric 60, keeping it horizontal or slightly taut, so that the water jet from the lower spray pipe 42 can precisely clean it. The lower surface of the woven fabric 60 is struck, and the woven fabric 60 enters above the large wire roller 501 from the lower small wire roller 503. The large wire roller 501 further stretches the woven fabric 60, and in conjunction with the upper spray pipe 41, ensures that the water sprayed from the spray pipe 41 evenly covers the upper surface of the woven fabric 60. Finally, the woven fabric 60 passes above the tension roller 502. The tension roller 502 maintains a constant tension of the woven fabric 60 throughout the entire conveying process by adjusting its own pressure, so as to avoid the woven fabric 60 from shifting due to slack or excessive tightness, and ensure that the cleaning is continuous and stable. When the fabric 60 moves to the cleaning area in a stable posture, the spray pipe 41 and the jet pipe 42 start up simultaneously, forming a top-and-bottom clamping cleaning mode to achieve efficient decontamination of the fabric 60. The wastewater after cleaning is collected through the overflow trough 102 at the bottom of the tank 10. The wastewater in the overflow trough 102 flows into the filter chamber through the transition pipe 22. At the same time, the circulation pump 21 starts to provide power for the wastewater flow, ensuring that the wastewater continuously enters the filter chamber 201. The motor 202 drives the filter screen 203 to rotate inside the filter chamber 201. When the wastewater flows through the filter screen 203, the filter screen structure of the filter screen 203 intercepts solid impurities such as lint and fiber fragments in the wastewater on the surface of the filter screen 203. After filtration... Clean water enters the filtration completion chamber. To prevent impurities on the surface of the filter screen 203 from clogging the filter screen, the backwash pipe 204 periodically sprays clean water to backwash the surface of the filter screen 203, flushing the slag stuck in the filter screen holes onto the slag plate 205. The slag wastewater on the slag plate 205 flows along the plate body into the outer slag hopper 206. Workers regularly clean the slag in the slag hopper 206. A small amount of wastewater generated by backwashing is discharged from the filter assembly 20 and sent to an external wastewater treatment device for treatment to avoid secondary pollution. After filtration, the clean water in the chamber is pumped back to the heat exchanger 30 by the circulation pump 21. After being reheated, it enters the spray main pipe 40, forming a closed-loop water circulation of cleaning-filtration-heating-re-cleaning. This significantly reduces water consumption and meets energy-saving and environmental protection requirements. After the water has been recycled multiple times (when impurities in the water accumulate to a certain concentration and the cleaning effect decreases), the drain pipe 11 at the bottom of the chamber 10 can be opened to drain the aging water inside the chamber 10 and replace it with new cleaning water to ensure stable cleaning quality in subsequent processes.
