Sewage treatment device capable of preventing blockage and automatically adding chemicals

Abstract

The invention relates to the technical field of sewage treatment, and discloses a sewage treatment device capable of preventing blockage and automatically adding chemicals, which comprises a collecting box, a filter cartridge is fixedly connected to the top of the collecting box, and a movable wheel is rotatably connected to the interior of the filter cartridge; six annularly-arranged inner cavities and six annularly-arranged chemical outlet holes are formed in the side wall of the movable wheel, movable rods are inserted into the opposite sides of the inner cavities, water baffles are fixedlyconnected to the sides, opposite to each other, of the movable rods, and six annularly-arranged filter plates are fixedly connected to the outer portion of the movable wheel. After the filter platesare blocked, when sewage on the filter plates is gathered to a certain degree, the movable wheels are driven to rotate by 60 degrees clockwise, so that the next filter plate rotates to the position tocontinue to filter the sewage, and the process is repeated until the blocked filter plates rotate to the position below the filter cartridge; and blockages on the filter plate fall into the collecting box under the action of gravity, so that the effect of automatically replacing the filter plate when the filter plate is blocked is achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device that prevents clogging and automatically adds chemicals. Background technique [0002] Sewage refers to the polluted discharge water from life and production. It can also be understood as water that has lost its original function. With the improvement of people's awareness of environmental protection, sewage treatment has attracted more and more attention. The method is generally to use a filter device to filter out the solid impurities in the sewage, and then add chemicals to the filtered sewage to treat the microorganisms in the sewage. [0003] The filter plate of the current sewage filtration device is very easy to clog when it is in use, requiring the staff to stop frequently for treatment, which is a waste of time and reduces the rate of sewage treatment, and it is difficult to grasp the dosage when adding chemicals. Therefore, we propose ...
