[0002] With the improvement of people's living standards, more and more people begin to suffer from various diseases. Medical treatment is a Chinese word with two meanings: medical treatment and disease treatment. Medical treatment is to diagnose and treat various diseases that occur in people's bodies. During the medical treatment process, various types of wastewater will be generated. The treatment of wastewater is an important issue in modern society. A medical wastewater treatment device is a device used in the process of medical waste treatment to treat medical wastewater, which can reduce the direct discharge of medical wastewater and reduce the impact of medical wastewater on the environment.

[0026] The bottom of the disinfection cylinder 2 is connected to the filter 3 through a second water delivery pipe 9 and a second servo pump 10. A water outlet pipe 11 is arranged at the water outlet end of the filter 3. The water outlet pipe 11 is connected to an external water pump. A uniform water inlet assembly 4 is arranged at the upper part of the filter box 1, and a filter element 5 is arranged inside the filter box 1 through a disassembly and assembly component 6;

[0027] The uniform water inlet assembly 4 enables the wastewater to enter the filter box 1 evenly for filtration and purification, improving the filtration and purification effect. The disassembly and assembly component 6 facilitates the installation and replacement of the filter element 5, improving the disassembly and assembly efficiency of the filter element 5.

[0028] The disassembly and assembly component 6 includes an inner cylinder 601, a sliding groove 602, a sliding column 604, a mounting bracket 605 and a second support ring 606. The inner cylinder 601 is fixedly installed at the middle position inside the filter box 1, and sliding grooves 602 are symmetrically arranged on both sides of the inner cavity of the inner cylinder 601. The sliding grooves 602 are slidably connected to the sliding column 604. A plurality of mounting brackets 605 are equidistantly arranged on the sliding column 604. A second support ring 606 is arranged at the bottom of the plurality of mounting brackets 605. The second support ring 606 is used for supporting the edge of the filter element 5. When installing the filter element 5, the filter element 5 is directly clamped in the mounting bracket 605, and the bottom edge is located on the second support ring 606, realizing stable installation.

[0029] The disassembly and assembly component 6 further includes a first support ring 603 and a suspension rod 607. The first support ring 603 is arranged at the bottom of the inner cavity of the inner cylinder 601, and the first support ring 603 is used for supporting the mounting bracket 605 at the bottom end of the sliding column 604. The suspension rod 607 is arranged at the top end of the sliding column 604, facilitating the overall lifting and disassembly of the mounting bracket 605.

[0030] In this embodiment, by providing a disassembly and assembly component in the filter box 1, it is convenient to disassemble and assemble multiple filter elements 5 as a whole, improving work efficiency. An inner cylinder 601 is provided inside the filter box 1. Slide grooves 602 are symmetrically arranged on both sides of the inner cavity of the inner cylinder 601. The slide grooves 602 are slidably connected to slide posts 604. When disassembling and replacing the filter elements 5 as a whole, directly use a lifting device to lift the slide posts 604 in the inner cylinder 601 and multiple mounting brackets 605 on the slide posts 604 through a suspension rod 607 for overall disassembly. Then, disassemble and replace the filter elements in the mounting brackets 605, and the mounting brackets 605 can be cleaned, improving the disassembly and assembly efficiency. Embodiment

[0031] Based on Embodiment 1, the uniform water inlet component 4 mentioned in Embodiment 1 is described as follows:

[0032] The uniform water inlet component 4 includes a top cover 401, a conical water distribution plate 403, a fixing rod 404, and a water inlet 405. Both sides of the top cover 401 are fixedly connected to the filter box 1 by bolts, and a conical water distribution plate 403 is arranged inside the top cover 401 through the fixing rod 404. Water distribution holes are evenly formed in the conical water distribution plate 403. The water inlet 405 is arranged above the top cover 401.

[0033] The uniform water inlet component 4 further includes a sealing cylinder 402. The sealing cylinder 402 is arranged outside the conical water distribution plate 403, and the bottom surface of the sealing cylinder 402 abuts against the top surface of the inner cylinder 601 to achieve docking with the inner cylinder 601.

[0034] In this embodiment, by providing the uniform water inlet component 4 at the upper part of the filter box 1, the waste water entering through the water inlet 405 is evenly dispersed and falls onto the lower filter elements 5 for filtration and purification, avoiding the waste water flowing to the filter elements 5 at a fixed point through the water inlet 405, ensuring that the waste water passing through the filter elements 5 can cover the entire filter element, improving the filtration efficiency. Using the conical water distribution plate 403 at the center inside the top cover 401, when the waste water flows from the water inlet 405 to the conical water distribution plate 403, the waste water falls along the surface of the conical water distribution plate 403 through the uniform holes to the filter elements 5 at the bottom, enabling the waste water to evenly cover the entire filter element 5, thereby improving the filtration efficiency and ensuring the filtration effect of the filter elements 5.

[0035] Working principle: First, the wastewater passes through the preliminary filtration device to filter impurities and then enters the filtration tank 1. The wastewater falls onto the conical water distribution plate 403 through the water inlet 405, and then falls onto multiple filter elements 5 in the inner cylinder 601 through the uniformly arranged water distribution openings on the water distribution plate for filtration. The water distribution plate evenly disperses the wastewater in the water inlet 405 onto the filter elements 5 for filtration. The wastewater purified by multiple filter elements 5 enters the disinfection cylinder 2. When the wastewater enters the disinfection cylinder 2, it is centrally collected, and then an appropriate amount of disinfectant is put into the disinfection cylinder 2 through the chemical inlet 13. The stirring mechanism 12 is used to fully mix and stir the wastewater and the disinfectant, so that the disinfectant reacts fully with the water to fully disinfect the water. After the disinfection treatment, the wastewater is pumped into the filter 3 by the second servo pump 10. The filter 3 filters the solid impurities in the water after reaction and disinfection. Finally, the disinfected and filtered wastewater is discharged to the designated place through the water outlet pipe 11;

[0036] When it is necessary to replace the filter element 5 in the filter 1, first remove the top cover 401, and then use the lifting device to directly pull out the entire mounting frame 605 from the inner cylinder 601 through the suspension rod 607, and then disassemble and replace the filter element in the mounting frame 605, which is convenient for disassembling and replacing the entire filter element 5 and improves the disassembly and assembly efficiency.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
