Filtering and impurity removing device for sewage treatment

Abstract

The invention discloses a filtering and impurity removing device for sewage treatment. The invention relates to the technical field of sewage treatment. The device comprises a supporting frame, a threaded rod is rotationally installed on the supporting frame, a reversing mechanism used for driving the threaded rod to rotate clockwise and anticlockwise alternately is arranged on the supporting frame, a double-shaft motor is fixed to the bottom in the supporting frame, and a lifting mechanism used for driving a water tank to adjust the vertical height is connected to the double-shaft motor in adriving mode. The reversing mechanism can drive the threaded rod to alternately rotate clockwise and anticlockwise, and the threaded rod drives a threaded sleeve block to enable a scraping mechanism to collect and filter floating objects on the surface of sewage in the water tank. Arranged pushing wheels can push a mesh basket, so that the mesh basket rotates to pour floating objects in the mesh basket into a collecting tank, and a rapid cleaning effect for the floating objects is achieved. An arranged cleaning mechanism can conduct transverse back-and-forth scraping action on a filter screen,it is guaranteed that meshes in the filter screen are not blocked, and the efficient filtering effect of the filter screen on insoluble impurities in sewage is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment filter and impurity removal device. Background technique [0002] Water pollution is water that reduces or loses the use value of water caused by harmful chemicals and pollutes the environment. Acids, alkalis, oxidants, and compounds such as copper, cadmium, mercury, and arsenic in sewage, organic poisons such as benzene, dichloroethane, and ethylene glycol, will kill aquatic organisms and affect drinking water sources and scenic spots. When the organic matter in the sewage is decomposed by microorganisms, the oxygen in the water is consumed, which affects the life of aquatic organisms. After the dissolved oxygen in the water is exhausted, the organic matter undergoes anaerobic decomposition, producing hydrogen sulfide, mercaptan and other unpleasant gases, which further deteriorates the water quality. Sewage treatment is the process of purifying sewa...

Problems solved by technology

[0003] The patent application publication number CN109914369 A discloses a device for removing floating objects in sewage, and specifically relates to a device that can remove floating objects in sewage and discharge them to a specified position, which greatly improves the convenience of removing floating objects in sewage , including a buoyancy-providing floating plate, a motor, a fishing mechanism and a cleaning mechanism, the top of the floating plate is fixedly connected to the mounting plate through a support plate, a motor is fixed on the mounting plate, the output end of the motor is connected to the driving shaft in rotation, and the driving shaft passes through the mounting plate And it is connected with the bearing, the lower part of the driving shaft is connected to the fishing mechanism for floating objects, and the fishing mechanism is connected to the cleaning mechanism for cleaning the fishing mechanism. Although this device is used for cleaning the sewage floating objects, the efficiency of fishing and processing is low. , can not achieve the effect of rapid removal of insoluble impurities in sewage, for this reason, a sewage treatment filter impurity removal device is now provided to solve the above technical problems
