Embodiment 1

[0025] see Figure 1-4 , a sewage treatment filtering impurity removal device, comprising a support frame 1, a water tank 2 is vertically slid inside the support frame 1, a threaded rod 3 is mounted on the support frame 1 for rotation, and a threaded sleeve block 4 is threaded on the threaded rod 3 , the threaded block 4 is provided with a scraping mechanism for scraping the floating matter of the sewage in the water tank 2, and the support frame 1 is provided with a reversing mechanism for driving the threaded rod 3 to alternately rotate clockwise and counterclockwise. A filter screen 20 is horizontally fixed in the water tank 2, and a cleaning mechanism for cleaning the filter screen 20 is installed at the lower end of the scraping mechanism. The inner bottom of the support frame 1 is fixed with a biaxial motor 19, and the biaxial motor 19 is driven and connected with a Drive the lifting mechanism of water tank 2 vertical height adjustment.

Embodiment 2

[0032] On the basis of Embodiment 1, further, the device is also provided with a scraping mechanism, which includes a telescopic rod 21 vertically slidably installed on the vertical rod 26, and a fixed connection between the telescopic rod 21 and the vertical rod 26 The spring 28 is resisted, and the brush plate 22 abutting against the filter screen 20 is fixed at the lower end of the telescopic rod 21 .

[0033] During the lateral movement of the vertical rod 26, the telescopic rod 21 on the vertical rod 26 drives the brush plate 22 to move laterally, at this time, the sediment on the filter screen 20 is scraped, which promotes the normal operation of the filter screen 20 and avoids clogging , prompting the filtering effect of the filter screen 20 on sewage.

[0034] In addition, the device is also provided with a lifting mechanism, including two threaded screw rods 32 coaxially fixed with the two output shafts of the biaxial motor 19 in opposite directions. Guide wheel 31 i...

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...
