Description

TECHNICAL FIELD

[0001] The utility model belongs to filter device technical field, especially, relate to a kind of aquaculture water centrifugal solid waste filter device. BACKGROUND

[0002] In the process of aquaculture, due to fish and shrimp feces and feed, 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 water oxygen content, affect fish and shrimp health, and even cause disease and death. Therefore, solid waste residues in the breeding pond must be removed in time.

[0003] Currently, there are many solid-liquid separation devices, and the most commonly used is the drum filter. However, when using the drum filter, 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 level will rise, and a large amount of water will enter the filter drum. When the weight of water and solid waste exceeds the carrying capacity of the filter and the filter screen, the filter and the filter screen will be crushed, causing equipment damage.

[0004] Although the conical filter drum has the gravity separation function of the inclined screen gravity water separator, such separation devices inherit the problem of conflict between water consumption and filtering efficiency. For example, if the inclination of the conical filter drum is small, the water permeability is good, the water consumption is small, but the water separation capacity is small, the washing effect of the filter screen is poor, and sediment is easily left, causing the filter screen to block, increasing the cleaning frequency and consuming clean water. Increasing the inclination increases the drainage effect of the conical filter drum, increases the water separation capacity, and improves the washing effect, but the water permeability decreases and the water consumption increases. The angle of the conical filter drum cannot be arbitrarily designed, and a balance between filtering efficiency and water consumption must be selected, making it difficult to achieve both.

[0005] At the same time, the ellipticity of the drum itself and the eccentricity during installation will affect the dynamic balance. To avoid dynamic imbalance, the speed and size of the drum are always limited, which limits the centrifugal separation effect and the large-scale of the drum. SUMMARY
