Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1 - Figure 4 As shown, a device for treating waste acid after water purification includes a conveying mechanism, a filtering mechanism and a motor 2 arranged on a treatment box 1. The motor 2 is installed on the top of the treatment box 1. A cover plate 15 is hinged at the top of the treatment box 1 near the outside of the motor 2. The conveying mechanism is arranged at the bottom end of the inside of the treatment box 1, and the conveying mechanism is fixedly connected to the output shaft of the motor 2. The filtering mechanism is arranged in the middle of the inner wall of the treatment box 1.

[0023] Furthermore, the conveying mechanism includes a hollow cylinder 4, which is fixedly connected to the bottom end of the treatment box 1, the output end of the motor 2 passes through the top of the treatment box 1 and the top of the hollow cylinder 4 and extends to the inside of the hollow cylinder 4, and the output end of the motor 2 is fixedly connected to the auger 3, the bottom end of the auger 3 is rotatably connected to the bottom end of the hollow cylinder 4, and a first filter screen 5 is fixedly installed at the bottom of the auger 3, a water inlet hole 6 is opened at the bottom of the outer wall of the hollow cylinder 4, a water outlet hole 7 is opened at the top of the outer wall of the hollow cylinder 4, and a water outlet pipe 8 is fixedly connected to the outside of the outer wall of the hollow cylinder 4 near the water outlet hole 7. Due to the first filter screen 5 set at the bottom of the auger 3, it is convenient to filter the impurities in the waste acid inside the treatment box 1, and the impurities are transported to the top of the hollow cylinder 4 by the auger 3 and discharged from the inside of the water outlet pipe 8.

[0024] Furthermore, it also includes a drain pipe 16. The bottom of one side of the treatment box 1 is fixedly connected to the drain pipe 16. The hollow cylinder 4 is arranged on the right side close to the drain pipe 16. A drain valve 17 is fixedly installed on the top of the drain pipe 16. The top of the other side of the treatment box 1 is fixedly connected to a sewage inlet pipe 18, which is convenient for closing the drain pipe 16 and confining the waste acid inside the treatment box 1, which is convenient for subsequent filtration work.

[0025] Furthermore, the filtering mechanism includes a support plate 9, which is fixedly connected to the middle part of one side of the processing box 1, and a partition plate 19 is fixedly connected to the top of the support plate 9. Two placement grooves 10 are opened at the top of the support plate 9, and the two placement grooves 10 are symmetrically arranged. A guide hole 11 connected to the placement groove 10 is opened at the bottom of the support plate 9, and the two guide holes 11 are symmetrically arranged. A placement rack 12 is placed inside the placement groove 10, and a second filter net 13 is fixedly installed on the inner wall of the placement rack 12. The placement rack 12 is placed inside the placement groove 10, so that the placement groove 10 can limit and fix the position of the placement rack 12.

[0026] Furthermore, the support plate 9 is located below the outlet pipe 8 , and the cross-section of the support plate 9 connected to the partition plate 19 is L-shaped, which is convenient for blocking the waste acid and guiding the waste acid to the two second filter screens 13 for filtration.

[0027] Furthermore, two extension plates 14 are fixedly connected to the top of the placement rack 12 near the two sides of the second filter screen 13. The two extension plates 14 are symmetrically arranged, so that when the staff opens the cover plate 15, it is convenient to pull the two extension plates 14 upward, so that the two extension plates 14 drive the placement rack 12 to be pulled out of the placement slot 10, so as to facilitate the cleaning of the second filter screen 13.

[0028] Working principle: First, close the drain valve 17, let the waste acid flow into the treatment box 1 through the sewage inlet pipe 18, turn upward and open the cover plate 15, so as to add the alkaline solution into the treatment box 1, and then start the motor 2, so that the motor 2 drives the auger 3 to rotate. Due to the rotation of the auger 3, it is convenient to stir and neutralize the waste acid and the alkaline solution in the treatment box 1, and then the waste acid in the treatment box 1 flows into the hollow cylinder 4 through the water inlet hole 6. Due to the first filter screen 5 set at the bottom of the auger 3, it is convenient to filter the impurities in the waste acid in the treatment box 1, and the impurities are transported by the auger 3, introduced into the water outlet pipe 8 from the inside of the water outlet hole 7, and then from the inside of the water outlet pipe 8 to the top surface of the box support plate 9, and then filtered twice through the second filter screen 13. Due to the continuous rotation of the auger 3, the waste acid in the treatment box 1 is continuously filtered, so as to fully filter the impurities in the waste acid;

[0029] Secondly, when the filtration is completed, open the drain valve 17 to allow the filtered waste acid to flow out of the treatment box 1 through the drain pipe 16 for subsequent treatment. Turn the cover plate 15 upward and open it, and pull the two extension plates 14 on a placement rack 12 to facilitate the staff to pull the placement rack 12 out of the placement slot 10 from the treatment box 1, so as to facilitate the cleaning of impurities on the second filter screen 13 and keep the second filter screen 13 free of blockage for subsequent use.
