Water purification device for aquaculture

Abstract

The invention relates to the technical field of aquaculture, in particular to a water purification device for aquaculture, a filter plate obliquely faces a water inlet and is arranged in a filter box, and a plurality of cleaning rollers capable of sliding back and forth are uniformly distributed on the side, facing the water inlet, of the filter plate; the adsorption plate is inserted into the filter box along the vertical direction and is positioned on the side, facing the water outlet, of the filter plate; the hopper is opened upwards and is arranged at the bottom ends, facing the water inlet, of the filter plate and the adsorption plate; the feeding end of the spiral conveyor is communicated with the narrow opening of the hopper; leakage holes are uniformly distributed in spiral blades of the spiral conveyor; the output ports of the aeration pipes face upwards and are arranged at the bottom end, facing the water outlet side, of the adsorption plate; the inclined plate obliquely faces the outer side of the water outlet and is arranged at the top of the aeration pipe, the guide plate obliquely faces the inner side of the water outlet and is arranged at the discharge port, and the horizontal gap between the inclined plate and the guide plate is lower than the horizontal plane. The device can automatically clean the filter plate, aquaculture water is sequentially filtered and purified twice, pollutants in the water can be effectively removed, the structure is relatively simple, and the cost is relatively low.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an aquaculture water purification device. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. Cleaning pond refers to thoroughly cleaning the pond before fish farming, eliminating silt, killing harmful fish and pests, etc., to ensure a good growth environment for fish. The degree of pollution is getting bigger and bigger, which makes the aquaculture water not suitable for the growth of aquatic products. If the aquatic products grow in the sewage for a long time, it is easy to cause the death of aquatic products, thus causing immeasurable economic losses. [0003] And aquaculture is the production activity of breeding, cultivating and harvesting aquatic...
