Description

Technical Field

[0001] This utility model relates to a sewage filtration and return water device for eel farming ponds. Background Technology

[0002] Eel is rich in various nutrients and has the effects of nourishing blood, removing dampness, and fighting tuberculosis. It is a good nutritional food for patients with chronic illness, weakness, anemia, and tuberculosis. Eel is a calcium-rich aquatic product; regular consumption can increase blood calcium levels and strengthen the body. Eel liver is rich in vitamin A, making it an excellent food for people with night blindness.

[0003] Therefore, eel farming has become an important aquaculture industry in coastal areas. During the eel farming process, wastewater is generated. The traditional method of water exchange is to replace all the wastewater in the farming pond with fresh water. This method of large-scale water exchange and intake not only wastes precious water resources, but also pollutes the aquatic environment with the wastewater discharged from eel farming, which is detrimental to environmental protection. Utility Model Content

[0004] This utility model improves upon the above-mentioned problems. Specifically, the technical problem to be solved by this utility model is to provide a sewage filtration and return water device for eel farming ponds, which effectively purifies the farming water in eel farming ponds to facilitate recycling and reduce water waste. At the same time, the eel feces filtered out by the filter can be treated and reused, realizing the resource utilization of wastewater.

[0005] This utility model is constructed as follows: it includes an eel farming pond, a sewage pond, and a filtration pond. The eel farming pond and the sewage pond are connected by a pumping pipe. The sewage pond and the filtration pond are connected by a drain pipe. The filtration pond and the eel farming pond are connected by a return water pipe. A filter is installed in the filtration pond. After the sewage in the sewage pond is filtered by the filter, it is pumped back to the eel farming pond through the return water pipe.

[0006] Furthermore, the filter includes a rotatable rotating cylinder frame and a microporous screen disposed on the peripheral surface of the rotating cylinder frame. The output end of the drain pipe extends into the interior of the rotating cylinder frame. A sludge discharge trough is provided in the upper part of the rotating cylinder frame. A spray assembly is provided above the rotating cylinder frame. The sludge discharge trough and the spray assembly are correspondingly arranged. The spray assembly is used to backwash the dirt on the microporous screen rotating below it into the sludge discharge trough for discharge.

[0007] Furthermore, a fixed ring is provided on one side of the rotating cylinder frame, and a guide wheel bracket is provided on the side of the fixed ring away from the rotating cylinder frame. Guide wheels are provided at the front and rear of the guide wheel bracket. The guide wheels are supported on the inner wall of the fixed ring and rotate in cooperation with it. A base plate is provided on the other side of the rotating cylinder frame. A gear ring is provided on the outer ring of the base plate. A motor is provided outside the gear ring. A gear is provided on the output shaft of the motor, and the gear meshes with the gear ring.

[0008] Furthermore, a fixed bearing seat is provided on the outer side of the base plate, and a shaft is fixed in the middle of the base plate, with the shaft rotating in conjunction with the fixed bearing seat.

[0009] Furthermore, the spray assembly includes a high-pressure spray pipe and a plurality of high-pressure nozzles disposed below the high-pressure spray pipe.

[0010] Furthermore, the high-pressure spray pipe is fixed to the upper edge of the sewage tank using a spray bracket.

[0012] Furthermore, the bottom surface of the outlet end of the sewage tank is provided with a sewage outlet, and a sewage pipe is connected to the outside of the sewage outlet.

[0013] Furthermore, a sedimentation tank is provided at the outlet end of the sewage pipe.

[0014] Compared with the prior art, this utility model has the following advantages: This device has a simple structure and is easy to use. The aquaculture water in the eel farming pond is pumped to the sewage tank through a pumping pipe. The water in the sewage tank is then pumped into the filter through a drain pipe. The motor drives the gear to rotate, which in turn drives the rotating cylinder and the microporous filter screen to rotate along the central axis of the rotating cylinder. The dirt attached to the lower microporous filter screen rotates with it to the bottom of the spray assembly. The nozzles of the spray assembly spray high-pressure water to backwash the microporous filter screen, removing solid dirt particles from the microporous filter screen. The water is flushed into the sewage trough and discharged, which cleans the microporous filter and purifies the water by separating solid waste. The purified water then enters the filtration tank through the microporous filter and is pumped back to the eel farming pond through the return pipe. This process filtration and purification of the farming water is beneficial to the growth of eels. While saving water resources, it also ensures that the eels have a good growth environment. At the same time, the filtered eel feces can be reused after treatment, turning waste into treasure and realizing the resource utilization of wastewater. Attached Figure Description
