[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6This utility model provides a technical solution: a waste liquid recycling deashing and softening device for leather tanning, comprising a base plate 1, a front box 2, a purification tank 3, a rear box 4, a rear water pump 5, a clamping sleeve 6, a main filter bag 7, a front water pump 8, an inlet pipe 9, an outlet pipe 10, a motor 11, a gear 12, a gear ring 13, a stirring rod 14, a feeding pipe 15, an end cap 16, a drain pipe 17, a retaining ring 18, a sealing gasket 19, a filtration mechanism 20, a sleeve 2001, and a secondary filter bag 2002. The front box 2, the purification tank 3, and the rear box 4 are sequentially fixed on the upper surface of the base plate 1, and the rear water pump 5 is installed at the upper end of the rear box 4. The clamping sleeve 6 is movably connected to the upper inner wall of the front box 2, and the main filter bag 7 is fixedly connected to the lower outer wall of the clamping sleeve 6. The front water pump 8 is installed at the edge of the upper surface of the purification tank 3, and the front water pump 8 is connected to the inlet water pump. Pipe 9 is connected to the front box 2, and the front water pump 8 is connected to the purification tank 3 through the outlet pipe 10. A motor 11 is installed on the upper surface of the purification tank 3 on the side of the front water pump 8. A gear 12 is fixedly connected to the lower end of the output shaft of the motor 11. A gear ring 13 is installed on the inner wall of the purification tank 3 on the side of the gear 12. A stirring rod 14 is fixedly installed on the inner wall of the gear ring 13. A feeding pipe 15 is fixedly connected through the surface of the purification tank 3 on the side of the motor 11. An end cap 16 is fitted on the upper outer wall of the feeding pipe 15. A drain pipe 17 is provided on the side of the purification tank 3. A retaining ring 18 is fixedly connected to the outer wall of the drain pipe 17. A sealing gasket 19 is adhered to the lower surface of the retaining ring 18. A filter mechanism 20 is installed on the outer wall of the drain pipe 17 below the sealing gasket 19. The filter mechanism 20 is located inside the rear box 4.

[0026] The front box 2 and the ferrule 6 form a sliding structure, which makes it easy for the user to move the ferrule 6 to install or remove the main filter bag 7.

[0027] The gear 12 and the gear ring 13 mesh with each other, so that when the motor 11 drives the gear 12 to rotate, the gear 12 drives the gear ring 13 to rotate.

[0028] The toothed ring 13 and the purification tank 3 form a rotating structure, which facilitates the stable rotation of the toothed ring 13 relative to the purification tank 3, thereby enabling the stirring rod 14 to rotate stably and mix the waste liquid and chemical reagents.

[0029] The feeding tube 15 and the end cap 16 are threaded together, which makes it easy for the user to rotate the end cap 16 to install or remove it.

[0030] The filtration mechanism 20 includes a sleeve 2001 and a secondary filter bag 2002. The sleeve 2001 is fitted onto the outer wall of the drain pipe 17, and the secondary filter bag 2002 is fixedly installed on the outer wall of the sleeve 2001. This facilitates the filtration of waste liquid in the purification tank 3 through the filtration mechanism 20, thereby preventing impurities in the waste liquid from affecting the subsequent treatment of the waste liquid.

[0031] The sleeve 2001 and the drain pipe 17 are threaded, which makes it easy for the user to rotate the sleeve 2001 to install or remove the secondary filter bag 2002.

[0032] The sleeve 2001 and the sealing gasket 19 are fitted together, which facilitates the improvement of the sealing performance of the sleeve 2001 through the sealing gasket 19.

[0033] Working principle: When using this leather tanning waste liquid recycling deashing and softening device, firstly as follows... Figure 1-6 As shown, the user pours the waste liquid generated from deashing and softening into the sleeve 6. The waste liquid then passes through the main filter bag 7 and falls into the front chamber 2. At this time, the main filter bag 7 filters the solid impurities in the waste liquid. Next, the user starts the front water pump 8, which pumps the filtered waste liquid from the front chamber 2 into the purification tank 3 through the inlet pipe 9 and outlet pipe 10. Then, the user injects chemical reagents into the purification tank 3 through the feeding pipe 15. Next, the user places the end cap 16 onto the feeding pipe 15 and tightens it. Then, the user starts the motor 11, which drives the gear 12 to rotate. The gear 12 then drives the gear ring 13 to rotate relative to the purification tank 3. The gear ring 13 then drives the stirring rod 14 to rotate, at which point the stirring rod 14 fully mixes the waste liquid and reagents. After the waste liquid and reagents are mixed, the user turns off the motor 11 and opens the drain pipe 17. The waste liquid in the purification tank 3 then flows out through the drain pipe 17. The liquid is discharged from the purification tank 3 via the liquid pipe 17. Next, the secondary filter bag 2002 filters the waste liquid to remove solid impurities. The filtered and treated waste liquid then flows into the rear tank 4. The user then starts the rear water pump 5 to discharge the waste liquid from the rear tank 4, thus completing the treatment of the leather tanning waste liquid. This facilitates the waste liquid's return to the deashing and softening process for recycling. When the filter bags need to be disassembled for cleaning, the user removes the retainer 6 from the front tank 2 to disassemble the main filter bag 7. Then, the user rotates the sleeve 2001 to detach it from the drain pipe 17 and the sealing gasket 19, thus disassembling the secondary filter bag 2002. At this point, the user pours out the impurities from the main filter bag 7 and the secondary filter bag 2002 and cleans them. Therefore, the device facilitates the disassembly and cleaning of the filter bags, preventing the accumulation of impurities in the filter bags from affecting the operation of the device and improving its practicality.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
