Filtering device for blue-green algae

Abstract

The invention discloses a filtering device for blue-green algae in the field. The device comprises a filtering seat, a driving servo motor, a water tank, a rotary core frame, a middle rotating shaft,a rotating base seat, a blue-green algae filtering cloth, a rubber scraping blade, an anchoring frame and a PLC; the filtering seat is provided with a water flow channel, and the upper end of the water flow channel is covered with a filter net screen with a screen-shaped structure; the rotary seat is rotatably installed in the middle position of the water flow channel of the filtering seat, and the part, located at the water flow channel, of the rotary seat is provided with a filter sieve cylinder; the rotary core frame is a revolution solid structure and coaxially sleeves the middle rotatingshaft, the middle rotating shaft can be rotatably inserted in the rotating base seat around a shaft, and the middle rotating shaft is further provided with a rotary driving mechanism capable of driving the middle rotating shaft to rotate around the shaft; and the rotary core frame is provided with an annular placement hole which has a circular ring structure and is coaxial with the middle rotatingshaft, and the blue-green algae filtering cloth is installed in the annular placement hole. According to the device disclosed by the invention, two pre-filtration can be performed before filtration of the blue-green algae, and the blue-green algae filtering cloth can be cleaned at any time.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a cyanobacteria filtering device. Background technique [0002] With the deterioration of the current domestic water environment, blue-green algae began to flood. In order to be able to drink clear water, it is necessary to filter the cyanobacteria in the water. At present, there are cyanobacteria filter cloths on the market, which can only pass through the water but not the cyanobacteria, so that the cyanobacteria can stay on the cyanobacteria filter cloth. However, because the water environment is very complicated, Pollutants include not only cyanobacteria, but also other sundries, and the cyanobacteria filter cloth will leave a lot of dirt after filtering once, which will lead to a decrease in filtration capacity. Contents of the invention [0003] The object of the present invention is to provide a cyanobacteria filtering device, which can perform two pre-filter...
