Device and method for removing and collecting microparticles in aquaculture water

Abstract

The invention relates to a device and a method for removing and collecting microparticles in aquaculture water. The device comprises a tank body for accommodating the aquaculture water, wherein a horizontal filter drum is arranged inside the tank body; a spacing distance is formed between the lower part of the filter drum and the bottom of the tank body; the filter drum can rotate under driving ofa power mechanism; a water inlet and a water outlet are formed in the side wall of the tank body; the water inlet is positioned outside a part corresponding to the end surface of the filter drum; thewater outlet is positioned inside the part corresponding to the end surface of the filter drum; sliding rails are arranged on the tank body; the sliding rails are arranged in the generatrix directionof the filter drum; a dirt sucking device capable of sliding along the sliding rails is arranged thereon; a set spacing distance is formed between a suction port of the dirt sucking device and the filter drum. The particle removing treatment capacity is high, and the energy consumption is low; backflushing is not required, and in the treatment process, a water resource is not consumed; manual maintenance is not required, and particle discharge is accurate; the particles collected after removal are substantially free of water and can be recycled.

Description

technical field [0001] The invention relates to an aquaculture water treatment device, in particular to a device and method for removing and collecting microparticles in aquaculture water. Background technique [0002] The removal and collection of microparticles in the water body is the top priority in the treatment of aquaculture water. If it is not removed in time, it will pollute the aquaculture water body. The ability of the microparticle removal device at the forefront of the circulating water system also directly affects the circulating water system. The processing load of subsequent equipment. [0003] In the existing aquaculture circulating water treatment, the removal and collection of microparticles in the water body adopts the rotary filter cartridge device, the water inlet is set inside the filter cartridge, and the water outlet is set outside the filter cartridge. A high-pressure spraying device is used to spray the filter cartridge from top to bottom to wash ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: in the microparticle removal device and equipment in industrialized circulating aquaculture, there are generally problems such as low processing capacity, large energy consumption, large water consumption, untimely backwashing and frequent manual maintenance; The final collected particulate matter has a high water content and cannot be reused
