Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to a purification device for aquaculture wastewater. Background Art

[0002] As a kind of agricultural and sideline production, aquaculture can contribute to the enrichment of the material civilization of society, and at the same time can increase the income of farmers as an industry. During the aquaculture process, the quality of water is related to the success of aquaculture. The accumulation of excess residual feed or excreta such as fish in the breeding pond or over-fertilization and other reasons will cause water pollution and fish death. Therefore, in order to ensure that the water quality in the breeding pond meets the growth conditions of fish, it is necessary to change the water in the breeding pond frequently.

[0003] The Chinese patent with the publication number CN219437959U discloses a circulating water purification device for aquaculture, belonging to the technical field of aquaculture, including an aquaculture pond, characterized in that: a purification tank is arranged on the right side of the aquaculture pond, and a first water pump is connected between the top of the purification tank and the aquaculture pond through a water pipe. An outlet is arranged at the top inside the purification tank, and the outlet is communicated with the output end of the first water pump. A motor is fixedly arranged at the bottom inside the purification tank. The beneficial effect of this patent is that when too many impurities are filtered in the purification tank, the motor can drive the purification tank on the surface of the turntable to rotate under the connecting plate on the right side, and the water spray nozzles on the lower surface of the connecting plate can wash the filtered impurities in the purification tank. Through the scouring of the water flow, the impurities can flow down from the mesh opening at the bottom of the purification tank and fall into the wastewater tank for storage. The cleaned purification tank can be reset to improve the subsequent water purification effect.

[0004] The above technical solution drives the purification tank on the surface of the turntable to rotate under the connecting plate on the right side through the motor. Through the scouring of the water flow, the impurities can flow down from the mesh opening at the bottom of the purification tank and fall into the wastewater tank for storage. However, in the above existing technical solution, when filtering impurities, it is actually filtering the impurities in the water flow. The purification tank is used to separate from the wastewater, and then the water flow is used to scour the impurities in the purification tank again. The impurities are intercepted by the purification tank and cannot be scoured clean, resulting in poor cleaning effect and affecting the quality of the subsequent water. Content of the Utility Model

The culture pond 1 is communicated with the purification tank 2 through the water inlet pipe 11. A water pump 6 is arranged on the side wall of the water inlet pipe 11. The water pump 6 is fixedly installed on the side wall of the culture pond 1. It also includes a motor 4. The motor 4 is fixedly installed on the bottom wall surface of the purification tank 2. A rotating rod 41 is fixedly installed at the output end of the motor 4. A plurality of cleaning brushes 42 are fixedly installed on the side wall of the rotating rod 41. A plurality of installation frames 5 are arranged on the inner side wall of the purification tank 2. A filtering element 51 is arranged inside the installation frame 5. The filtering element 51 is composed of a filter screen, an adsorption plate and a reverse osmosis membrane. The cross section of the filtering element 51 is semicircular. The cleaning brush 42 is in contact with the filtering element 51. Through the setting of the cleaning brush 42, it is convenient to clean the impurities filtered by the filtering element 51. A water tank 3 is arranged on the right side of the purification tank 2. A water pump 2 is arranged inside the water tank 3. A connecting pipe 31 is fixedly installed at the output end of the water pump 2. A plurality of drain pipes 32 are fixedly installed on the side wall of the connecting pipe 31. The drain pipes 32 correspond to the cleaning brushes 42 and are located above the cleaning brushes 42. Two spray nozzles 33 are fixedly installed on the side wall of the drain pipes 32. The spray nozzles 33 are inclined downward. A fixing plate 21 is fixedly installed on the inner bottom wall surface of the purification tank 2. The fixing plate 21 divides the inside of the purification tank 2 into a circulation chamber and a sewage discharge chamber. The rotating rod 41 is rotatably installed on the fixing plate 21. A recovery pipe 12 is fixedly installed on the side wall of the purification tank 2. The culture pond 1 is communicated with the circulation chamber through the recovery pipe 12. A sewage discharge pipe 22 is fixedly installed on the bottom wall surface of the purification tank 2. The sewage discharge pipe 22 is communicated with the sewage discharge chamber. When it is necessary to clean the impurities on the surface of the filtering element 51, start the motor 4. The motor 4 drives the rotating rod 41 to rotate. The rotating rod 41 drives the cleaning brush 42 to rotate. The cleaning brush 42 rotates to clean the filtering element 51, scrapes off the impurities on the installation frame 5 and rotates them above the sewage discharge chamber. By starting the water pump 2, the impurities attached to the cleaning brush 42 are washed through the spray nozzles 33, which is convenient for the cleaning brush 42 to clean the filtering element 51 again.

The wastewater is filtered and purified by multiple filter elements 51. The purified water will flow into the lower circulation cavity. Open the one-way valve 7, and the purified water will re-enter the aquaculture pond 1 through the recovery pipe 12. By repeating this cycle, the water quality in the aquaculture pond 1 can be effectively purified to ensure the aquaculture effect. When it is necessary to clean the impurities on the surface of the filter element 51, start the motor 4. The motor 4 drives the rotating rod 41 to rotate. The rotation of the rotating rod 41 drives the cleaning brush 42 to rotate. The cleaning brush 42 rotates to clean the filter element 51, scrape off the impurities on the mounting frame 5 and rotate them above the sewage discharge cavity. Then, by starting water pump 2, the impurities attached to the cleaning brush 42 are flushed through the nozzle 33, which facilitates the cleaning brush 42 to clean the filter element 51 again. After that, they fall into the sewage discharge cavity along with the water flow. Open the valve 8, and the impurities flow out from the sewage discharge pipe 22, eliminating the need for manual cleaning and achieving good cleaning effect.
