[0021] Example

[0022] refer to Figures 1 to 4 This embodiment of a wastewater treatment device with multi-stage filtration includes a base 1, a filter box 3 fixedly connected to the top of the base 1, a multi-stage filter plate 6 slidably connected to the inner wall of the filter box 3, a first groove 5 matching the multi-stage filter plate 6 on the inner wall of the filter box 3, a top cover 11 snapped onto the top of the filter box 3, a protective plate 16 slidably connected to the top of the top cover 11, a second groove 15 matching the protective plate 16 on the top of the top cover 11, and a groove 13 on the top of the top cover 11. An electromagnet 14 is fixedly connected to the inner side of the groove 13, covering the inner side of the groove 13. In use... The multi-stage filter plate 6 can filter sewage in multiple stages. The protective plate 16 can block the top of the top cover 11, which can provide good protection. The attraction of the electromagnet 14 can effectively limit the position of the protective plate 16 to improve the stability of the installation of the protective plate 16. When the multi-stage filter plate 6 needs to be removed separately, first turn off the electromagnet 14, then open the protective plate 16 through the second slide 15, and finally pull out the multi-stage filter plate 6 to be removed through the first slide 5. This can achieve the effect of convenient and quick individual disassembly and assembly of the multi-stage filter plate 6, and also effectively improve the efficiency of subsequent cleaning and maintenance of the multi-stage filter plate 6.

[0023] refer to Figure 1 and Figure 2 The bottom of the protective plate 16 is made of magnetic material, and the top of the protective plate 16 is fixedly connected to a handle 17. The handle 17 has an arc-shaped corner. The presence of the handle 17 makes it easier for the user to grip, so that the protective plate 16 can be pulled more conveniently and quickly.

[0024] refer to Figure 2The top of the protective plate 16 has a rectangular opening 18, which communicates with the inside of the filter box 3. An observation window 19 is fixedly connected to the inside of the rectangular opening 18, and the observation window 19 covers the inside of the rectangular opening 18. Because of the opening of the rectangular opening 18, the user can directly view the inside of the filter box 3 through the observation window 19 without opening the protective plate 16, which is conducive to the user to observe the status of sewage treatment at all times and can effectively improve the safety of sewage treatment work.

[0025] refer to Figures 1 to 3 The top of the filter box 3 is provided with a slot 9, which is located on the four sides near the corners of the top of the filter box 3. The bottom of the top cover 11 is fixedly connected with a matching block 12. The block 12 is engaged with the inside of the slot 9. The top cover 11 is engaged with the top of the filter box 3 through the slot 9 and the block 12. The top of the filter box 3 is fixedly connected with a sealing ring 10. The top of the sealing ring 10 is in contact with the bottom of the top cover 11. The sealing ring 10 is made of rubber. Due to the presence of the block 12, the engagement of the block 12 can effectively limit the position of the top cover 11, thereby preventing the top cover 11 from shifting. The sealing ring 10 can effectively seal the connection point of the top cover 11, thereby achieving a good waterproof sealing effect. When the top cover 11 needs to be removed, the block 12 can be pulled out. It also facilitates the user to maintain the top structure of the top cover 11 later.

[0026] refer to Figures 1 to 4 The bottom inner side of the filter box 3 is provided with a positioning groove 4. The bottom of the multi-stage filter plate 6 is fixedly connected with a positioning block 8 that matches the positioning groove 4. The positioning block 8 is snapped into the inside of the positioning groove 4. The top of the multi-stage filter plate 6 is fixedly connected with a handle 7. The corners of the handle 7 are arc-shaped. Due to the presence of the positioning block 8, the snapping of the positioning block 8 can effectively limit the position of the multi-stage filter plate 6, thereby improving the stability of the installation of the multi-stage filter plate 6 and preventing the multi-stage filter plate 6 from shifting. At the same time, it will not hinder the subsequent removal of the multi-stage filter plate 6.

[0027] refer to Figure 1 The bottom of the base 1 is fixedly connected to the support leg 2. The support leg 2 is fixedly connected to the four sides of the bottom of the base 1 near the corner. The bottom of the support leg 2 is coated with an anti-slip layer. The anti-slip layer covers the support leg 2. Due to the presence of the support leg 2, the bottom of the base 1 can be effectively supported. The anti-slip layer can improve the anti-slip ability of the bottom of the support leg 2 and effectively improve the stability of the base 1.

[0028] refer to Figure 1The top of the top cover 11 is provided with a water inlet 20, which is connected to the inside of the filter box 3. A water outlet pipe 21 is provided on one side of the filter box 3, which is connected to the inside of the filter box 3. A switch valve 22 is provided at the top of the water outlet pipe 21, which is connected to the inside of the water outlet pipe 21. Due to the setting of the water inlet 20, it is convenient for sewage to enter. The switch valve 22 can be used to open or close the water outlet pipe 21 so that the filtered water can be discharged later.

[0029] Operating principle and advantages: During use, the multi-stage filter plate 6 can perform multi-stage filtration of sewage. The protective plate 16 can block the top of the top cover 11, providing good protection. The attraction of the electromagnet 14 can effectively limit the position of the protective plate 16, improving the stability of its installation. When the multi-stage filter plate 6 needs to be removed individually, first turn off the electromagnet 14, then open the protective plate 16 through the second slide 15, and finally pull out the multi-stage filter plate 6 to be removed through the first slide 5. This achieves convenient and quick individual disassembly and assembly of the multi-stage filter plate 6, and also effectively improves the efficiency of subsequent cleaning and maintenance of the multi-stage filter plate 6. The handle 17 facilitates the user's gripping, making it easier and faster to pull the protective plate 16. Due to the rectangular opening 18, the user can directly view the inside of the filter box 3 through the observation window 19 without opening the protective plate 16, thus facilitating the user's constant observation of the sewage treatment status and effectively improving the sewage treatment process. For operational safety, the presence of the locking block 12 effectively limits the position of the top cover 11, preventing displacement. The sealing ring 10 effectively seals the connection points of the top cover 11, providing a good waterproof seal. When the top cover 11 needs to be removed, the locking block 12 can be pulled out, facilitating future maintenance of the top structure of the top cover 11. The presence of the positioning block 8 effectively limits the position of the multi-stage filter plate 6, improving the stability of the installation and preventing displacement. It also does not hinder the later removal of the multi-stage filter plate 6. The presence of the support leg 2 effectively supports the bottom of the base 1, and the anti-slip layer enhances the anti-slip capability of the bottom of the support leg 2, effectively improving the stability of the base 1. The inlet 20 facilitates the entry of wastewater, and the outlet pipe 21 can be opened or closed via the switch valve 22 to discharge the filtered water.
