Problems solved by technology

[0004] As a solid-liquid separation device, the rotary drum filter is an indispensable equipment in aquaculture. However, in the prior art, the filter barrel of the rotary drum filter rotates continuously, which consumes a lot of energy; and the frame of the filter barrel is mostly made of metal materials. Heavy weight requires more power to drive it to rotate, which also results in high energy consumption

Abstract

The invention provides a drum type micro-filtering machine which comprises a housing, a filtering barrel with a filtering net, a backwashing device, a control system and a motor, wherein the filtering barrel is located in the housing, a rotary bracket of the filtering barrel is fixedly connected with the housing, the backwashing device is arranged between the filtering barrel and the housing; the control system comprises a water level sensor arranged in the filtering barrel and a control device assembly arranged outside the housing. By adopting an automatic water level detection function, by virtue of a water level difference, the rotation of the filtering barrel and the starting of backwashing are controlled, the advantages of reducing energy consumption and labor force are achieved; the drum type micro-filtering machine is economic and applicable, simple to operate, and low in production and operation costs.

Description

technical field [0001] The invention belongs to the field of water treatment, and relates to a filtering device, in particular to a rotary drum microfilter. Background technique [0002] As a reliable source of food, aquaculture is developing rapidly around the world, but the current traditional farming model that consumes resources and pollutes the environment has seriously restricted the sustainable development of aquaculture. [0003] The closed circulation aquaculture system adopts certain engineering facilities and water treatment facilities to recycle the aquaculture discharge water after treatment, so as to achieve high yield, high efficiency, high quality and "zero" pollution. However, due to the particularity of seawater, the working environment is humid, the air has high salt content, and is highly corrosive, which puts forward high requirements on the reliability, corrosion resistance and stability of the equipment. At the same time, in order to further reduce the...
