Detailed Description

A novel sewage pretreatment filtering device is shown in figures 1-4 and comprises a box body 9, a motor 1, a speed reducer 2 and a transmission filtering component, wherein a main chain wheel 4 is arranged on a main transmission shaft 3 of the speed reducer 2, the transmission filtering component comprises a roller 7 installed in the box body 9, a water inlet and a water outlet are respectively arranged on two side walls of the box body 9, a partition plate 18 is further arranged at the water inlet, a spiral conveyor 8 is arranged at the water outlet of the box body, a scraper 12 is arranged at the feed inlet of the spiral conveyor 8, and the upper end of the scraper 12 penetrates through the discharge outlet at the upper part of the box body and is tightly pressed and attached to the wall of the roller 7 through a scraper pressing rod 11; a roller shaft 6 is arranged in the center of the roller 7, and one end of the roller shaft 6 is driven to rotate by the speed reducer 2 and the motor 1 through the transmission of the double-row chain wheel 5; the double-row chain wheel 5 drives the screw conveyor 8 to rotate through the chain. The inner walls of the box bodies on two sides of the roller shaft 6 are respectively and fixedly provided with an eccentric disc 14, the opposite disc surfaces of the eccentric discs 14 are respectively provided with eccentric circular grooves, nail tooth rods 16 are respectively installed between the eccentric circular grooves through bearings 15 which are arranged in a matching way, nail teeth 10 are evenly arranged on the nail tooth rods 16 at intervals, the roller shaft 6 between the eccentric discs 14 is respectively provided with a radial plate 13 at intervals through a radial plate hub 19, the radial disc surfaces of the radial plates 13 are respectively provided with a guide sliding groove 20, and the nail tooth rods 16 slide along the guide sliding grooves 20 in the radial direction; the peripheral surface of the roller 7 is respectively provided with through holes which are matched and corresponding to the nail teeth 10. The inner peripheries of the two sides of the roller 7 are in clearance fit with the outer periphery of the eccentric disc 14. The spacing plate 18 is provided with grooves at regular intervals, and the grooves are matched with the nail teeth 10.

The roller shaft 6 and the web 13 are fixedly installed through a web hub 19, threaded holes are formed in the circumferential direction of the web 13, the web 13 and the roller 7 are fixedly connected through the threaded holes, the roller 7, the web 13 and the roller shaft 6 are integrated into a whole, and when the double-row chain wheel rotates, the roller 7 rotates along with the roller shaft 6. Thereby performing a rotating function of the drum 7.

The eccentric discs 14 at the two ends of the roller 7, the roller shaft 6 and the side plates of the box body 9 are installed through a bearing and a bearing seat 17, the eccentric discs 14 at the moment form a fixed structure with the box body 9, and when the roller 7 integrally rotates, the positions of the eccentric discs 14 are fixed.
