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.

[0023] Please see Figures 1-4 This utility model provides the following technical solution: a multi-stage filtration wastewater treatment device, including a housing 1, a sealing door 2 connected to the front surface of the housing 1, an inlet pipe 3 provided on the top surface of the housing 1, a drain pipe 4 provided on the bottom surface of the housing 1, a protrusion 5 connected to the inner surface of the housing 1, a groove 6 formed on one side surface of the protrusion 5, a slider 7 connected to the inner surface of the groove 6, a mounting frame 8 connected to one side surface of the slider 7, a filter basket 9 connected to the inner surface of the mounting frame 8, a transparent observation window 10 provided on the front surface of the mounting frame 8, a slot 11 formed on one side surface of the slider 7, and a filter basket 9 connected to the inner surface of the slot 11. One end of the insertion rod 12 and the other end of the insertion rod 12 pass through the insertion hole 13 opened on one side surface of the housing 1. A connecting block 14 is connected to one end of the insertion rod 12. A vertical plate 15 is connected to one side surface of the connecting block 14. Mounting brackets 16 are connected to both sides of the housing 1. A motor 17 is connected to one side surface of the mounting bracket 16. The output end of the motor 17 extends into the mounting bracket 16 and is connected to one end of the screw 18. A bearing 19 is set in a slot opened on one side surface of the housing 1. A vertical plate 15 is connected through one end of the screw 18. A connecting mechanism is also provided on the top surface of the mounting frame 8.

[0024] The slider 7, mounting frame 8, filter basket 9, transparent observation window 10, slot 11, positioning groove 20, positioning block 21, groove 22, bolt 23 and fixing hole 24 constitute an integrated filter mechanism.

[0025] Preferably, the connecting mechanism includes: a positioning groove 20, a positioning block 21, a groove 22, a bolt 23, and a fixing hole 24. The top surface of the mounting frame 8 is provided with a positioning groove 20, the inner surface of the positioning groove 20 is connected to a positioning block 21, the top surface of the positioning block 21 is provided with a groove 22, the inner surface of the groove 22 is connected to one end of a bolt 23, and the other end of the bolt 23 passes through the positioning block 21 and extends into the fixing hole 24 provided on the bottom surface of the positioning groove 20.

[0026] In practical use, the positioning block 21 is slidably placed into the positioning groove 20, and the bolt 23 is slidably placed into the groove 22. By tightening the bolt 23, the bolt 23 can be screwed through the positioning block 21 into the fixing hole 24, so that the position of the positioning block 21 is fixed in the positioning groove 20, allowing the filter basket 9 to be installed on the mounting frame 8. At the same time, after the bolt 23 is tightened, the head of the bolt 23 will be in the groove 22, so that no part of the bolt 23 will protrude from the positioning block 21.

[0027] Preferably, the slider 7 is slidably connected to the protrusion 5 via the groove 6, and the insert rod 12 is slidably connected to the slider 7 via the slot 11.

[0028] In practical use, the slider 7 can slide in the groove 6, so that the mounting frame 8 can slide and pull on the protrusion 5 through the slider 7. When one end of the plug rod 12 slides into the slot 11, the position of the slider 7 can be fixed in the groove 6, and the position of the mounting frame 8 can be fixed inside the box 1.

[0029] Preferably, the insertion rod 12 is slidably connected to the housing 1 through the insertion hole 13, and the insertion rod 12 is slidably connected to the protrusion 5.

[0030] In actual use, the insertion rod 12 can slide in the insertion hole 13, so that the movement of the insertion rod 12 can slide through the protrusion 5, and one end of the insertion rod 12 can enter the slot 11.

[0031] Preferably, the motor 17 is electrically connected to an external power source via a control switch, the output end of the motor 17 is fixedly connected to the screw 18, and the screw 18 is threadedly connected to the vertical plate 15.

[0032] In practical use, the motor 17 can be controlled by a switch. The output end of the motor 17 can drive the screw 18 to rotate in the bearing 19, so that the vertical plate 15 on the screw 18 will move on the screw 18, thereby allowing the vertical plate 15 to drive the insertion rod 12 on the connecting block 14 to move.

[0033] Preferably, the positioning block 21 is slidably connected to the mounting frame 8 through the positioning groove 20, and the bolt 23 is threadedly connected to the fixing hole 24 through the positioning block 21.

[0034] In practical use, the positioning block 21 can be slidably placed into the positioning groove 20, and then the bolt 23 is screwed through the positioning block 21 into the fixing hole 24, so that the position of the positioning block 21 can be fixed in the positioning groove 20.

[0035] Working principle: When using this multi-stage filtration wastewater treatment device, wastewater is fed into the tank 1 through the inlet pipe 3, causing it to slide downwards within the tank 1. The wastewater then passes through the filter baskets 9 inside the multiple mounting frames 8 within the tank 1, where the filter baskets 9 filter and collect impurities. After multi-stage filtration, the wastewater is discharged through the drain pipe 4 at the bottom of the tank 1. When the filter baskets 9 inside the mounting frames 8 need cleaning or maintenance, first open the sealing door 2. Then, start the motor 17 using the switch. The output end of the motor 17 drives the screw 18 to rotate within the bearing 19. This causes the vertical plate 15 on the screw 18 to slide the insertion rod 12 on the connecting block 14, allowing one end of the insertion rod 12 to slide out of the slot 11 and into the insertion hole 13. Pulling the mounting frame 8 then allows the sliders 7 on both sides of the mounting frame 8 to move from the convex... The mounting frame 8 slides out of the groove 6 on block 5, allowing it to be disassembled from the housing 1. This allows operators to easily clean and maintain the filter basket 9 inside the mounting frame 8, avoiding the need for manual tightening of the positioning screw to disassemble the mounting frame 8, thus saving operation time and facilitating the maintenance of the sewage treatment device. Secondly, when a filter basket 9 on a mounting frame 8 is damaged, the mounting frame 8 is first separated from the housing 1, and then the bolt 23 is tightened so that one end of the bolt 23 can be separated from the fixing hole 24. At this time, the positioning block 21 can slide in the positioning groove 20, allowing the filter basket 9 to slide and be pulled out of the mounting frame 8. This allows operators to replace the damaged filter basket 9 individually, avoiding the need to replace the entire filter mechanism after the filter basket 9 is damaged, thus saving maintenance costs.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
