Technical Field

[0001] The utility model relates to the technical field of sewage discharge devices, in particular to a sewage discharge device for aquaculture ponds. Background Technique

[0002] The sewage discharge device for aquaculture ponds is a special equipment designed to meet the needs of water purification and pond bottom maintenance during the aquaculture process. In aquaculture, as the breeding cycle extends, a layer of sludge composed of residual baits, biological excrements, dead organisms and their decomposition products gradually accumulates at the bottom of the breeding pond. These sludges not only occupy the breeding space, reduce the effective water volume, but also easily breed harmful microorganisms, affect the water quality, and thus threaten the health and growth of cultured organisms. Therefore, it is of great significance to remove these sludges in a timely and effective manner to maintain the stability of the breeding environment, improve the breeding efficiency, and ensure the quality of aquatic products.

[0003] The problem of sludge accumulation at the bottom of aquaculture ponds is one of the common challenges in the aquaculture industry. Over time, residual baits, biological excrements, algae remains and microbial metabolites in the breeding pond continuously deposit at the bottom of the pond, gradually forming a thick sludge layer. This sludge layer not only occupies valuable breeding space, but also is not convenient to clean the sludge at the bottom of the breeding pond through a sludge pump. Therefore, a sewage discharge device for aquaculture ponds is needed to solve the above problems. Content of the Utility Model

The bottom of the main aquaculture pond body is fixedly connected with a sewage discharge pipe. One end of the sewage discharge pipe far away from the main aquaculture pond body is fixedly connected with a sludge pump. The sludge pump is located below the main aquaculture pond body. The inner wall of the main aquaculture pond body is fixedly installed with a filter disc through bolts. The top surface of the filter disc is fixedly connected with an isolation cylinder. The bottom surface of the filter disc is rotatably connected with a driving disc through a sealed bearing. The outer surface of the driving disc is fixedly connected with a plurality of scraping plates arranged in a circumferential array. All the plurality of scraping plates are slidably connected with the main aquaculture pond body. The top surface of the driving disc is fixedly connected with a driving rod.

Inside the main aquaculture pond body, an assembly ring is fixedly installed through bolts. The top surface of the assembly ring is fixedly connected with a support disc. The top surface of the support disc is in contact with the bottom surface of the driving disc. One end of the sewage discharge pipe far away from the sludge pump is located inside the assembly ring.

[0007] Preferably, from any of the above solutions, the driving rod is located inside the isolation cylinder. The outer surface of the isolation cylinder is fixedly connected with a vertically arranged scale. The axes of the isolation cylinder, the driving disc, and the driving rod coincide.

[0012] Preferably, from any of the above solutions, the top surface of the support disc is provided with positioning holes. The bottom surface of the driving disc is fixedly connected with positioning pins. The positioning pins are rotatably connected with the support disc through the positioning holes.

[0013] Compared with the prior art, the advantages and beneficial effects of the present utility model are as follows:

[0014] 1. When sewage discharge operation of the aquaculture pond is required, the staff can open the valve on the sewage discharge pipe, and then start the sludge pump to discharge the sludge accumulated at the bottom of the aquaculture pond.

When the driving disc rotates, it will drive the positioning pin to rotate inside the positioning hole, which can limit the rotation of the driving disc, and then make the driving disc rotate more stably.
