[0002] In the process of aquaculture, due to fish and shrimp feces and feed residues, a large amount of solid waste residues are produced every day, if not removed in time, the solid waste residues will cause bacteria to increase dramatically after rotting, 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 easily cause blockage, if the filter screen is blocked during use, the water drainage is not smooth, which will cause the water level to rise, a large amount of water needs to enter the drum of the filter, 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, at the same time, due to the eccentricity of the drum itself and the eccentricity during installation, the dynamic balance is affected, the speed and size of the drum are also limited, when the drum rotates, vibration will be generated due to the inability to achieve dynamic balance, the existing drum filter commonly uses lateral water flushing, which uses the lateral impact force of water flow to drive the drum to rotate, the lateral impact force is small, which is difficult to drive the drum to rotate, and the large lateral impact force will destroy the dynamic balance and generate vibration, increase the equipment damage rate, and reduce the service life of the equipment.
[0004] Although the conical drum filter has the gravity water separation function of the inclined screen separator, can wash away the solid waste impurities separated in the drum through the flow separation function, and prevent blockage, but such separation device also inherits the problem of conflict between water consumption and filtering efficiency of the inclined screen separator, for example, the small inclination of the conical filter drum has good water permeability and small water consumption, but the water separation amount is small, the washing effect of the filter screen is poor, and sediment is easily left, causing the filter screen to be blocked, the cleaning frequency needs to be increased, the working cycle is shortened, and clean water is consumed, increasing the inclination increases the drainage effect of the conical filter drum, the flow separation amount is increased, and the washing effect is improved, but the water permeability is reduced, and the water consumption is increased, the angle of the conical filter drum cannot be designed arbitrarily, and a balance between the filtering efficiency and the water consumption must be selected, and it is difficult to achieve both.
