[0026] 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.

[0027] Please see Figure 1-4 A wastewater treatment device with multi-stage filtration function includes a wastewater treatment tank 1, a mounting plate 2, mounting bolts 3, pipes 4, and a multi-stage filter screen body 5. The bottom end of the wastewater treatment tank 1 is fixedly connected to the corresponding mounting plate 2. The mounting plate 2 is fixedly installed by multiple sets of mounting bolts 3. The left and right ends of the wastewater treatment tank 1 are connected to the corresponding pipes 4. The wastewater treatment tank 1 is connected to the multi-stage filter screen body 5 through a disassembly and assembly mechanism.

[0028] The disassembly and assembly mechanism also includes a fixing plate 6, a pressing plate 7, a threaded rod 8, a drive plate 9, a first plate 10, and a second plate 11. An installation groove 12 is provided at the center of the top of the sewage treatment tank 1. A pressing groove 13 is symmetrically provided at the top of the fixing plate 6. The bottom of the fixing plate 6 is fixedly connected to the top of the multi-stage filter body 5. The multi-stage filter body 5 is inserted into the sewage treatment tank 1 through the installation groove 12. The fixing plate 6 and the corresponding installation groove 12 are slidably and sealingly connected. A sealing gasket is provided at the connection between the fixing plate 6 and the installation groove 12. Rotating mechanisms are provided on the front and rear sides of the sewage treatment tank 1. The rotating mechanisms are rotatably connected to the bottom of the corresponding second plate 11. The top of the second plate 11 is fixedly connected to one side of the bottom of the corresponding first plate 10. The threaded rod 8 is threadedly and rotatably connected to the center of the top of the first plate 10. The bottom of the threaded rod 8 is rotatably connected to the top of the corresponding pressing plate 7. The pressing plate 7 is located in the pressing groove 13 and presses the fixing plate 6. The bottom of the drive plate 9 is fixedly connected to the top of the corresponding threaded rod 8.

[0029] When this device is in use

[0030] Install the multi-stage filter body: Insert the multi-stage filter body 5 into the sewage treatment tank 1 through the installation groove 12, so that the fixing plate 6 and the installation groove 12 are slidably and sealed. The sealing gasket at the connection plays a sealing role. At this time, the multi-stage filter body 5 is installed in the sewage treatment tank 1.

[0031] Fixing the multi-stage filter body: Rotate the second plate 11, causing the second plate 11 to move the pressing plate 7 directly above the pressing groove 13. Then rotate the drive plate 9, which drives the threaded rod 8 to rotate. Since the threaded rod 8 is threadedly connected to the top center of the first plate 10, the threaded rod 8 will move downwards while rotating. When the threaded rod 8 moves downwards, it drives the pressing plate 7 to move downwards. Under the guidance of the guide rod 15, the pressing plate 7 slides accurately downwards. At the same time, the limiting plate 16, under the limiting action of the limiting groove 18 and the limiting rod 17, prevents the pressing plate 7 from shifting. When the pressing plate 7 moves into the pressing groove 13, it presses the fixing plate 6, thereby fixing the multi-stage filter body 5 inside the sewage treatment tank 1.

[0032] Wastewater treatment: Wastewater enters the wastewater treatment tank 1 through pipes 4 that connect to the left and right ends of the wastewater treatment tank 1. After passing through the multi-stage filter screen body 5, the treated water is discharged through the corresponding pipes 4.

[0033] Disassembling the multi-stage filter body: When cleaning or replacing the multi-stage filter body 5, rotate the drive plate 9 in the reverse direction. The drive plate 9 drives the threaded rod 8 to rotate upward, and the threaded rod 8 drives the pressing plate 7 to move upward, causing the pressing plate 7 to disengage from the pressing groove 13 and releasing the pressure on the fixing plate 6. Then rotate the entire mechanism to a position that does not obstruct the removal of the fixing plate 6, and then remove the multi-stage filter body 5 from the mounting groove 12 for cleaning or replacement.

[0034] As a preferred embodiment of the above, the rotating mechanism further includes a support plate 14. The two sets of support plates 14 are fixedly connected to the front and rear sides of the corresponding sewage treatment tank 1. The bottom end of the second plate 11 is rotatably connected to the corresponding support plate 14. The pressing plate 7 is slidably connected to the first plate 10 through a guide mechanism.

[0035] As a preferred embodiment of the above, the guiding mechanism further includes a guide rod 15, and the guide rod 15 is symmetrically installed on the top of the pressing plate 7, and the guide rod 15 slides through the corresponding first plate 10.

[0036] As a preferred embodiment of the above, it further includes a limiting plate 16 and a limiting rod 17. A limiting groove 18 is provided in the middle of one side of the second plate 11. One side of the pressing plate 7 is fixedly connected to the corresponding limiting plate 16. A limiting rod 17 is fixedly installed on the outside of the limiting groove 18. The limiting plate 16, the corresponding limiting groove 18, and the limiting rod 17 are slidably fitted together.

[0037] As a preferred embodiment of the above, a protective pad 19 is also included, and the bottom end of the pressing plate 7 is fixedly connected to the top end of the corresponding protective pad 19.

[0038] As a preferred embodiment of the above, it also includes stiffening plates 20, and multiple sets of stiffening plates 20 are provided at the connection between the support plate 14 and the sewage treatment tank 1 and at the connection between the first plate 10 and the second plate 11.
