Description

Technical Field

[0001] This utility model relates to the technical field of aquaculture wastewater treatment systems, specifically an aquaculture wastewater treatment system. Background Technology

[0002] The development of animal husbandry generates a large amount of sewage and wastewater. If this sewage and wastewater is discharged directly without being filtered, it will cause great pollution to the rural environment.

[0003] A search revealed CN222454628U, which discloses a wastewater treatment device for livestock farms. The device includes a water tank, with several springs fixedly installed at the bottom of two recesses. A top plate is fixedly installed at the other end of each spring. Inside the water tank, on opposite sides of a gear, racks are slidably connected. Both racks mesh with the gear. One rack is fixedly connected to the side of the top plate closest to it, while the top of the other rack is fixedly installed with a spring. By incorporating an automatic pushing mechanism, during replacement, the operator pulls out the top activated carbon filter. The interaction of springs, gears, racks, and springs causes the top plate to push the remaining activated carbon filters upwards, gradually increasing their position. A new activated carbon filter is then inserted into the bottom of the trough. This makes the entire replacement process more convenient, faster, and saves time and effort.

[0004] However, in actual operation, the activated carbon filter at the top needs to be manually removed for cleaning, and then manually installed at the bottom. The operation is time-consuming and labor-intensive, and therefore needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a wastewater treatment system for aquaculture to solve the problems mentioned in the background art.

[0013] Beneficial effects

[0014] This utility model provides a wastewater treatment system for aquaculture, which has the following beneficial effects:

[0015] This aquaculture wastewater treatment system uses a movable seat to move towards the filter tank body, which in turn moves a toggle plate towards the activated carbon filter. Once the toggle plate contacts the filter, it slides upwards. When it reaches the top of the slot, gravity causes the lower end of the toggle plate to insert into the slot. The movable seat then moves away from the filter tank body, and the toggle plate moves the activated carbon filter, allowing it to be pulled out of the trough. An upward spring force from the top plate allows the lower layer of activated carbon filter to be moved to the top. A filter cleaning mechanism then automatically cleans the activated carbon filter. After cleaning, a support frame moves downwards along a limiting slide bar, moving the cleaned filter to the bottom of the trough. Finally, a pusher plate moves laterally to push the cleaned filter back into the bottom of the trough, completing the installation. The entire process of disassembling, cleaning, and installing the activated carbon filter is automated, saving time and labor, and improving efficiency. Attached Figure Description

[0021] 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.

[0022] Please see Figure 1-4This utility model provides a technical solution: a livestock wastewater treatment system, including a filter tank body 1, wherein the filter tank body 1 is a prior art that has been disclosed. A chute 2 is provided on one side of the filter tank body 1, and multiple activated carbon filter screens 3 are slidably connected to the inner side of the chute 2. A top plate 4 is elastically connected to the inner bottom of the filter tank body 1. A strip plate 5 is fixedly connected to the side of the filter tank body 1, and filter screen cleaning mechanisms 6 are provided on both sides of the strip plate 5. A strip groove 7 is provided on the lower surface of the strip plate 5, and a filter screen cleaning mechanism 6 is slidably connected within the strip groove 7. A laterally movable seat 8 has a sliding actuating plate 9 at its lower end. The lower end of the actuating plate 9, near the activated carbon filter 3, has a chamfered edge. The surface of the activated carbon filter 3 has a slot 10 that engages with the actuating plate 9. A limiting slide rod 11 is fixedly connected to the lower surface of the strip plate 5. A support plate 12 is fixedly connected to the lower end of the limiting slide rod 11. A height-adjustable support frame 13 is slidably connected to the surface of the limiting slide rod 11. A laterally movable push plate 14 is slidably connected to the inner side of the support frame 13. The movable seat 8... The water filter tank body 1 moves, causing the actuating plate 9 to move towards the activated carbon filter 3. When the actuating plate 9 contacts the activated carbon filter 3, it slides upwards. Once the actuating plate 9 is above the slot 10, its lower end inserts into the slot 10 under gravity. Then, the movable seat 8 moves away from the water filter tank body 1. By actuating the activated carbon filter 3 with the actuating plate 9, the activated carbon filter 3 can be pulled out of the slide groove 2. Using the upward elastic force applied by the top plate 4, the lower activated carbon filter 3 can be replaced to the uppermost layer. Then... The filter cleaning mechanism 6 can automatically clean the activated carbon filter 3. After cleaning, the carrier frame 13 moves downward along the limiting slide bar 11, which can move the cleaned activated carbon filter 3 to one side of the bottom of the slide trough 2. Finally, the push plate 14 moves laterally, which can push the cleaned activated carbon filter 3 back into the bottom of the slide trough 2, thereby completing the installation of the activated carbon filter 3. The entire disassembly, cleaning and installation of the activated carbon filter 3 can be automated, saving time and effort, saving labor and improving efficiency.

By using the threaded connection between the first adjusting screw 18 and the movable seat 8, and cooperating with the strip groove 7 to limit the movement of the movable seat 8, the lateral movement of the movable seat 8 can be realized.

[0025] Multiple sections of electric telescopic rods 19 are fixedly connected to the lower surface of the support frame 13, and the lower ends of the multiple sections of electric telescopic rods 19 are fixedly connected to the upper surface of the support plate 12. By extending and retracting the multiple sections of electric telescopic rods 19, the support frame 13 can be raised and lowered, thereby adjusting the height of the support frame 13.

The second adjusting screw 21 is threadedly connected to the push plate 14. When the second servo motor 20 works, it can drive the second adjusting screw 21 to rotate. In conjunction with the inner wall of the support frame 13, the push plate 14 is limited, and the lateral movement of the push plate 14 can be realized.

[0027] The filter cleaning mechanism 6 includes a side support plate 22, a water supply main pipe 23, and multiple high-pressure rotary nozzles 24. The side support plate 22 is fixedly connected to the side of the strip plate 5, and the multiple high-pressure rotary nozzles 24 are equidistantly fixedly connected to the surface of the side support plate 22.
