Description

Technical Field

[0001] The utility model relates to the technical field of dye production, in particular to a dyeing liquid filtering device for electrostatically dyeing cloth. Background Art

[0002] Dyes refer to a class of organic compounds that can give other substances bright and firm colors. During the dye production process, dye particles are prone to aggregation during the dissolution process, which can lead to uneven dyeing problems. In addition, there are insoluble impurities mixed in the dye during production, which require the use of a filtration device for filtration and purification. After a general filtration device has been running for a long time, the filter holes on the filter component are clogged with accumulated impurities, affecting the filtration effect. The device needs to be stopped for cleaning, which prolongs the working time and reduces the filtration efficiency. Utility Model Content

[0022] The device can grind the larger material particles in the dye, remove impurities through multiple filtrations, and improve the purity of the dye; the dye is poured into the feed tank 1 from the liquid inlet pipe 4, and the larger material particles blocked by the filter plate A5 can be crushed by the grinding assembly 6, and the dye enters the transition box 3 through the feed tank 1, and the dye extracted from the transition box 3 by the activated liquid pump 9 is sent to the three-way valve 10 through the infusion pipe 12. The three-way valve 10 can select the filter tank 2 connected to the infusion pipe 12, and the dye entering the filter tank 2 falls back into the transition box 3 after being filtered by the filter plate B7, completing an infusion cycle. After completing multiple infusion cycles, the dye is filtered multiple times by the filter plate B7, and the purity is improved. After the valve 16 is opened, the dye leaves the transition box 3 from the liquid outlet pipe 15. When there are many impurities accumulated in the filter tank 2 and the filtering effect of the filter plate B7 is affected, the filter tank 2 connected to the infusion pipe 12 can be changed by operating the three-way valve 10, and the filter tank 2 that is out of the infusion cycle can be cleaned up at this time without affecting the normal operation of the device. The dye in the transition box 3 is stirred by the stirring assembly 13 to make the impurities in the dye float up, thereby preventing the impurities from being deposited at the bottom of the transition box 3 instead of flowing into the filter tank 2 with the dye, thereby affecting the filtering effect.

[0023] Furthermore, the grinding assembly 6 includes a grinding roller 17, a rotating rod A18 and a motor A19. A rotating rod A18 is provided on the vertical center axis of the feed tank 1. The top of the rotating rod A18 is rotatably connected to the top of the feed tank 1. A motor A19 is provided on the top of the feed tank 1. The driving rod of the motor A19 is coaxially connected to the top of the rotating rod A18. The left and right sides of the bottom end of the rotating rod A18 are respectively rotatably connected with a grinding roller 17 along the horizontal direction. The filter plate A5 is circular in shape. The two grinding rollers 17 are in the same straight line direction, and the grinding rollers 17 roll against the upper surface of the filter plate A5.

[0024] After the motor A19 is started, it can drive the rotating rod A18 connected to its driving rod to rotate, and then drive the grinding roller 17 connected to the rotating rod A18 to rotate around the central axis of the feed tank 1. The grinding roller 17 rolling on the filter plate A5 crushes the material particles on the filter plate A5.

[0025] Furthermore, the stirring assembly 13 includes a stirring rod 20, a rotating rod B21 and a motor B22.

[0026] After the motor B22 is started, it can drive the rotating rod B21 connected to its driving rod to rotate, and then drive the stirring rod connected to the rotating rod B21 to rotate around the central axis of the transition box 3. The rotating stirring rod 20 stirs the dye in the transition box 3, driving the impurities in the dye to float, thereby reducing the probability of impurities depositing at the bottom of the transition box 3.

[0029] Furthermore, a liquid level gauge 26 is provided on the side wall of the transition box 3. The staff can conveniently check the liquid level of the dye in the transition box 3 through the liquid level gauge 26 to judge whether the amount of dye in the transition box 3 is appropriate.

[0030] The working principle and use process of this utility model:

[0031] After the staff starts the motor A19, the dye is poured into the liquid inlet pipe 4. The dye enters the transition box 3 after being filtered by the filter plate A5. After being crushed by the grinding roller 17 blocked by the filter plate A5, it falls into the transition box 3 with the dye. After the transition box 3 is filled with enough dye, the liquid pump 9 and the motor B22 are started. The stirring rod 20 driven by the motor B22 stirs the dye so that the impurities in the dye remain in a floating state and can flow with the dye. The dye in the transition box 3 is driven by the liquid pump 9 through the liquid infusion pipe 12, the three-way valve 10 and the liquid distribution pipe 11 to the selected filter tank 2. The dye falls back into the transition box 3 after being filtered by the filter plate B7 in the filter tank 2, completing an infusion cycle. After multiple infusion cycles, the dye filtering operation is completed. After the dye is filtered, the liquid pump 9 and the motor B22 are turned off, the valve 16 is opened, and the dye is discharged from the liquid outlet pipe 15.

[0032] The above are only specific application examples of the utility model, and do not constitute any limitation on the protection scope of the utility model. Any technical solution formed by equivalent transformation or equivalent replacement falls within the protection scope of the utility model.
