Device for removing blue algae on filtering net

Abstract

The invention discloses a device used for removing blue alga on a filter screen, in particular a device which removes dense alga on the filter screen of an alga water separating machine and leads the filter screen to be dredged. The device is characterized in that the device comprises a brush roller and a motor, wherein, the brush roller comprises a mainshaft; the excircle of the mainshaft is provided with elastic brush sheets which are bar-shaped hard plastic sheets and are uniformly and compactly distributed. Two ends of the mainshaft are rotatablely arranged on a bracket by a bearing; the motor is also arranged on the bracket; the mainshaft is parallel to the output shaft of the motor. One end of the mainshaft and the output shaft of the motor are respectively provided with a pulley; two pulleys are connected with each other by a transmission belt. By adopting the device, the dense alga bonded to the filter screen can be removed and the removal effect is good.

Description

technical field [0001] The invention relates to a cyanobacteria treatment device. Specifically, it is a device for removing concentrated algae on the filter screen of the algae water separator and dredging the filter screen. Background technique [0002] Blue-green algae outbreaks have been known to occur in polluted lake water. Blue-green algae outbreaks will further deteriorate the water environment. Therefore, when a cyanobacteria bloom occurs, salvage is a must. The salvaged cyanobacteria have a high water content and must be filtered before they can be used. Commonly used cyanobacteria filtration devices all use rotating sieves or vibrating sieves. Since cyanobacteria are colloidal organisms, a large number of cyanobacteria will adhere to the filter screen and block the mesh during the filtration process, affecting the filtering effect. In order to solve this problem, the traditional method is to use water recoil method or compressed air injection. Although the con...

AI Technical Summary

Problems solved by technology

Although the concentrated algae adhering to the filter can be washed down by the water flow recoil method, the washed water will further dilute the algae water and reduce the concentration of blue-green algae. This method is less effective

Since cyanobacteria are colloidal organisms with high viscosity, it is difficult to peel off the concentrated algae adhering to the filter screen by jetting compressed air

Therefore, the above two methods are less effective
