[0030] By adopting the above scheme, through the cooperation of the sliding component, the medicine spraying component and the adjustment component, the medicine barrel 5 drives the medicine spraying main pipe 501 and the medicine spraying branch pipe 502 to move along the inside of the treatment box 1 for uniform medicine spraying. At the same time, the medicine spraying plate 7 can rotate by itself to spray the medicine liquid on the sewage in a wide range and at multiple angles, so that the medicine liquid and the sewage are in more sufficient and uniform contact, which effectively improves the efficiency of industrial wastewater purification.

[0031] Specifically, a guide support plate 4 is fixedly connected between both ends of the middle part of the filter screen plate 2 and the filter screen box 3, the dosing tube 5 slides along the inner wall of the guide support plate 4, the top of the dosing tube 5 is fixedly connected with a threaded block 503, the middle thread of the threaded block 503 is threadedly sleeved with a threaded rod 504, both ends of the threaded rod 504 are connected to the front and rear inner walls of the treatment box 1 through bearings, a motor 505 is fixedly installed on the back of the treatment box 1, and the output end of the motor 505 is fixedly connected to the threaded rod 504, an inlet pipe 101 is fixedly installed on the top of the treatment box 1, and a water outlet pipe 102 is fixedly installed on the bottom back of the treatment box 1.

[0032] The above scheme is adopted to effectively improve the stability of the installation structure of the dosing cylinder 5. By starting the motor 505 to drive the threaded rod 504 to rotate, the threaded block 503 can drive the dosing cylinder 5 to move along the guide support plate 4, so as to facilitate the mobile and uniform dosing of the sewage inside the treatment box 1, which is beneficial to improving the efficiency of industrial wastewater purification. During operation, the sewage first enters the interior of the treatment box 1 from the water inlet pipe 101, and then passes through the coarse filtration of the filter plate 2, the fine filtration of the filter box 3 and the dosing treatment in turn, and finally the purified water is discharged through the outlet pipe 102.

[0033] Specifically, a filter cavity 301 is provided inside the filter box 3, a guide channel 302 is opened through the middle of the filter box 3, the dosing main pipe 501 slides along the guide channel 302, a support rail 303 is fixedly connected to the middle bottom end of the filter box 3, the push block 9 moves along the support rail 303, and limit blocks 304 are fixedly connected on both ends of the support rail 303.

[0034] By adopting the above scheme, it is convenient to place activated carbon particles in the filter cavity 301, and extremely fine colloids, suspended particles, etc. in the water can be filtered out, thereby improving the efficiency of industrial wastewater purification. The stability of the connection structure between the drug administration main pipe 501 and the filter box 3 is improved through the guide channel 302, which facilitates the drug administration main pipe 501 and the drug administration branch pipe 502 to drive the telescopic block 8 to move. By supporting the slide rail 303, the stability of the connection structure of the push block 9 is improved, which facilitates the cooperation between the push block 9 and the telescopic block 8.

[0035] Specifically, the upper end of the dosing branch pipe 502 is fixedly connected to the two sides of the dosing main pipe 501, and a guide port 506 connected to the dosing branch pipe 502 is opened on the side wall of the dosing main pipe 501. A support rod 804 is fixedly connected to the outer wall of the dosing branch pipe 502, and a bottom plate 805 is fixedly connected to the bottom of the support rod 804. A slide plate 803 is fixedly connected to the bottom side wall of the telescopic block 8, and the slide plate 803 is slidably sleeved on the corresponding support rod 804. A telescopic spring 806 is sleeved on the support rod 804, and both ends of the telescopic spring 806 are respectively fixedly connected to the dosing branch pipe 502 and the slide plate 803.

[0036] By adopting the above scheme, it is convenient to elastically support the telescopic block 8, thereby improving the stability of the connection between the telescopic block 8 and the drug administration main pipe 501. When the telescopic block 8 moves upward, the guide port 506 can be closed, thereby stopping the supply of the drug solution. When the telescopic block 8 moves downward and resets, the guide port 506 can be reopened, thereby facilitating the drug solution to enter the drug administration branch pipe 502 and be sprayed into the sewage by the drug administration plate for purification treatment. This makes it convenient to adjust and control the drug administration amount, facilitate accurate drug administration, avoid the waste of excess drug solution, and improve the efficiency of industrial wastewater purification treatment.

[0037] Specifically, the interior of the push block 9 is a hollow structure and the upper end of the push block 9 is a convex arc shape. Both ends of the bottom of the push block 9 are fixedly connected with a slide frame 901. The slide frame 901 is provided with a slide hole 902.

[0038] By adopting the above scheme, a stable connection and convenient movement of the push block 9 is achieved. When it is necessary to treat the sewage with medicine, the medicine liquid enters the medicine dispensing plate from the medicine dispensing tube 5, the medicine dispensing main pipe 501, the diversion port 506, and the medicine dispensing branch pipe 502 and is sprayed into the sewage, and moves back and forth at the corresponding upper part between the limit blocks 304 to achieve uniform medicine dispensing. When medicine dispensing is not needed, the medicine dispensing main pipe 501 drives the telescopic stopper 8 to move to the position of the push block 9. Since the push block 9 is limited by the limit block 304 at one end, the telescopic stopper 8 abuts against the push block 9 at this time, which can drive the telescopic stopper 8 to move elastically upward, thereby achieving the diversion port 506. 06 is closed to stop the drug administration. When it is necessary to continuously stir and mix the drug solution and sewage, the telescopic block 8 can drive the push block 9 to continue to move, so that the stirring work can be achieved without drug administration, which is convenient for the full reaction of the drug solution and further enhances the industrial wastewater purification efficiency. It has high flexibility. When the drug administration work needs to be resumed, the telescopic block 8 drives the push block 9 to the limit block 304 at the other end, and the push block 9 is restricted again, which can make the telescopic block 8 slide away from the push block 9, and the telescopic block 8 is reset. At the same time, the push block 9 is reset under the action of the plastic spring 903, and the adjustment and use are flexible.

A positioning groove 802 is provided on the bottom of the telescopic stopper 8, and the upper end of the push block 9 slides into the positioning groove 802.

[0040] By adopting the above scheme, the wedge-shaped groove 801 facilitates the telescopic stopper 8 to slide along the push block 9 when it moves, so that it is pushed upward by the push block 9. The positioning groove 802 improves the stability of the connection between the push block 9 and the telescopic stopper 8, and facilitates the telescopic stopper 8 to drive the push block 9 to move synchronously, so that the sewage can still be stirred and mixed without administering medicine, thereby improving the mixing efficiency of the medicine liquid and then improving the purification efficiency.

[0041] Specifically, the middle part of the upper end of the medicine sprinkling plate 7 is connected to the drug administration branch pipe 502 through a bearing, a medicine sprinkling cavity 701 is provided inside the medicine sprinkling plate 7, and the bottom of the medicine sprinkling plate 7 is fixedly connected with evenly distributed medicine spraying nozzles 702, and the medicine sprinkling cavity 701 is connected to the drug administration branch pipe 502 and the medicine spraying nozzles 702.

[0042] The above scheme is adopted to facilitate the rotary spraying operation of the liquid medicine, and realize the uniform spraying operation in a wide range and at multiple angles.

[0043] Specifically, the upper end of the rotating rod 6 is fixedly connected to the middle of the lower end of the medicine spraying plate 7, the lower end of the rotating rod 6 is fixedly connected to the gear 602, the inner bottom of the processing box 1 is fixedly connected to the guide rack 103, and the guide rack 103 and the gear 602 are meshingly connected.

[0044] By adopting the above scheme, when the rotating rod 6 follows the movement of the dosing barrel 5 and the dosing branch pipe 502, it can drive the gear 602 to move along the guide rack 103, realize the rotation of the gear 602, and then drive the rotating rod 6 and the medicine spraying plate 7 to rotate, thereby realizing the rotary medicine spraying operation.

[0045] Specifically, a stirring rod 601 is fixedly connected to the rotating rod 6 .

[0046] The above solution makes it convenient for the stirring rod 601 to fully stir and mix the sewage and the liquid medicine mixture, so that the liquid medicine reaction efficiency is more sufficient.

[0047] Working principle of the present invention: When in use, sewage enters the interior of the treatment box 1 from the water inlet pipe 101, and first passes through the coarse filtration of the filter screen plate 2 to filter out larger impurities and waste, and then passes through the fine filtration of the filter screen box 3 to filter out extremely fine colloids, suspended particles, etc. in the water, and then enters the inner bottom of the treatment box 1, and the motor 505 is started to drive the dosing cylinder 5 to move, and the telescopic block 8 drives the push block 9 to reach the limit block 304 at the other end, and the telescopic block 8 that continues to move slides away from the push block 9, and the telescopic block 8 resets downward to open the guide port 506, and the liquid medicine enters the dosing disk from the dosing cylinder 5, the dosing main pipe 501, the guide port 506, and the dosing branch pipe 502 and is sprayed It is sprinkled into the sewage and moved back and forth to perform medication. The coordination of the rotating rod 6, the gear 602 and the guide rack 103 enables the medication disk to self-rotate, and a wide range, multi-angle and uniform medication spraying operation is performed. At the same time, the stirring rod 601 achieves sufficient stirring of the medication liquid. When the medication dosage is sufficient and the medication dosage needs to be closed, the telescopic stopper 8 reaches the limit block 304 at one end and slides onto the push block 9 to drive the synchronous movement, thereby enabling the medication liquid to be stirred and mixed even without medication. This facilitates the full reaction of the medication liquid, realizes the flexible adjustment of the medication dosage, and effectively improves the efficiency of industrial wastewater purification. Finally, the purified water can be discharged through the outlet pipe 102.
