[0002] In the process of aquaculture, due to fish and shrimp feces and feed residues, a large amount of solid waste residues will be produced every day, if not removed in time, the solid waste residues will cause bacteria to increase dramatically, destroy water quality, reduce the oxygen content of water, affect the health of fish and shrimp, and even cause disease and death, therefore, the solid waste residues in the culture pond must be removed in time.

[0003] At present, the commonly used solid-liquid separation device equipment is endless, and the most used is the drum filter, but when the drum filter is used, the mesh size is too large to affect the filtering effect, and the mesh size is too small to cause blockage, if the filter screen is blocked during use, the water level will rise, a large amount of water will enter the filter drum, when the weight of water and solid waste exceeds the bearing capacity of the filter and filter screen, the filter and filter screen will be crushed, resulting in equipment damage.

[0004] Although the conical filter cylinder has the gravity separation effect of the inclined screen gravity water separator, such separation device inherits the problem of conflict between water consumption and filtering efficiency, for example, if the inclination of the conical filter cylinder is small, the water permeability is good, the water consumption is small, but the water separation amount is small, the washing effect of the filter screen is poor, and the sediment is easy to remain, causing the filter screen to be blocked, the cleaning frequency needs to be increased, and clean water is consumed, increasing the inclination, the drainage effect of the conical filter cylinder increases, the water separation amount increases, and the washing effect improves, but the water permeability decreases, and the water consumption increases.
