[0024] As Figure 1As shown in the figure, a sedimentation tank for sewage treatment includes a sedimentation tank 100. Inside the sedimentation tank 100, there is a frame 110. On the upper outer wall of the frame 110, a hollow diversion shell 111 is fixedly connected. On one outer wall of the sedimentation tank 100, an L-shaped bracket 120 is fixedly connected. On the upper outer wall of the L-shaped bracket 120, a first driving motor 130 is installed. The output shaft end of the first driving motor 130 passes through the upper side wall of the L-shaped bracket 120 and is fixedly connected to a screw rod 140. The lower end of the screw rod 140 is threadedly passed through a lifting block 150 and is rotatably connected to the upper side wall of the sedimentation tank 100. On one side wall of the lifting block 150 away from the L-shaped bracket 120, a follower block 160 is fixedly connected. On the bottom wall of the follower block 160, two symmetrically distributed connecting rods 170 are fixedly connected. The lower ends of the connecting rods 170 are fixedly connected to the hollow diversion shell 111. Inside the frame 110, there is an impact assembly 200. At the bottom of the sedimentation tank 100, there is an anti-blocking assembly 300. The output shaft of the first driving motor 130 can drive the screw rod 140 to rotate. When the screw rod 140 rotates, under the limitation of the guide rod, the lifting block 150 will drive the follower block 160 to move downward. Driven by the connecting rod 170, the frame 110 will move downward together, and the side wall of the sedimentation tank 100 is cleaned during the movement process.
[0025] Specifically, as Figure 2 and Figure 3 shown, for the sedimentation tank for sewage treatment, the impact assembly 200 includes a fixing plate 210, a rotating rod 220, a connecting rope 230, an impact ball 240, a second driving motor 250 and a bevel gear 260. Inside the frame 110, four groups of fixing plates 210 are annularly arranged. The number of each group of fixing plates 210 is two and they are symmetrically distributed. A rotating rod 220 is rotatably connected between the two fixing plates 210. A number of connecting ropes 230 are uniformly arranged on the rod wall of the rotating rod 220. The other end of the connecting rope 230 is fixedly connected to an impact ball 240. On one of the fixing plates 210, a second driving motor 250 is installed. The output shaft end of the second driving motor 250 is fixedly connected to one end of one of the rotating rods 220. A bevel gear 260 is fixedly connected to the end of the rotating rod 220. The bevel gears 260 are meshed with each other. The output shaft of the second driving motor 250 can drive one of the rotating rods 220 to rotate. When this rotating rod 220 rotates, driven by a plurality of meshed bevel gears 260, the other rotating rods 220 rotate together, so that the connecting rope 230 drives the impact ball 240 to swing, and the impact ball 240 will impact the side wall of the sedimentation tank 100 to break up the agglomerated blocks.
[0026] Specifically, as Figure 4As shown in the figure, for the sedimentation tank used in sewage treatment, the anti-blocking component 300 includes an anti-blocking cylinder 310, a support plate 320, a submersible motor 330, a feeding auger 340, a sewage discharge pipe 350, and a solenoid valve 351. The anti-blocking cylinder 310 is fixedly connected to the bottom wall of the sedimentation tank 100, the support plate 320 is fixedly connected to the lower inner wall of the sedimentation tank 100, the submersible motor 330 is installed on the upper side wall of the support plate 320, the output shaft end of the submersible motor 330 passes through the support plate 320 and is fixedly connected to the feeding auger 340. The bottom end of the feeding auger 340 is rotationally connected to the lower inner wall of the anti-blocking cylinder 310. The sewage discharge pipe 350 is fixedly connected to the bottom wall of the anti-blocking cylinder 310, and the solenoid valve 351 is installed on the sewage discharge pipe 350. During sewage discharge, the solenoid valve 351 and the submersible motor 330 are opened. The output shaft of the submersible motor 330 drives the feeding auger 340 to rotate. The precipitated sludge and other impurities will enter the anti-blocking cylinder 310. As the feeding auger 340 rotates continuously, these sludges will be extruded downward and then discharged to the outside through the sewage discharge pipe 350, effectively avoiding blockage.
[0027] Specifically, as Figure 1 shown in the figure, for the sedimentation tank used in sewage treatment, guide rods are fixedly connected to the upper inner wall of the L-shaped bracket 120 on the front and back sides of the screw rod 140 respectively. The lower ends of the guide rods slide through the lifting block 150 and are fixedly connected to the upper side wall of the sedimentation tank 100. The guide rods can guide and limit the lifting block 150, so that it can only move up and down and will not rotate with the screw rod 140.
[0028] Specifically, as Figure 2 shown in the figure, for the sedimentation tank used in sewage treatment, a number of spray nozzles 112 are evenly arranged on the upper outer wall of the hollow diversion shell 111. The spray nozzles 112 can spray water onto the side wall of the sedimentation tank 100 for high-pressure flushing.
[0029] Specifically, as Figure 2 shown in the figure, for the sedimentation tank used in sewage treatment, a scraping plate 113 is fixedly sleeved on the outside of the hollow diversion shell 111. The scraping plate 113 can scrape and clean the side wall of the sedimentation tank 100.
[0030] Specifically, as Figure 2 shown in the figure, for the sedimentation tank used in sewage treatment, a water supply pipe 1111 is connected to the hollow diversion shell 111. The other end of the water supply pipe 1111 is connected to an external water supply device. The external water supply device transports water into the hollow diversion shell 111 through the water supply pipe 1111.
[0031] In the specific implementation of the present utility model, when the sedimentation tank 100 shows a caking situation, the first drive motor 130 and the second drive motor 250 are started. The output shaft of the second drive motor 250 can drive one of the rotating rods 220 to rotate. When the rotating rod 220 rotates, under the transmission of a plurality of meshing bevel gears 260, the remaining rotating rods 220 rotate together, so that the connecting rope 230 drives the impact ball 240 to swing. The impact ball 240 will hit the side wall of the sedimentation tank 100 to break up the caked blocks. The external water supply device transports water through the water supply pipe 1111 to the hollow diversion shell 111, and the nozzle 112 sprays the water onto the side wall of the sedimentation tank 100. The output shaft of the first drive motor 130 can drive the screw rod 140 to rotate. When the screw rod 140 rotates, under the limit of the guide rod, the lifting block 150 will drive the follower block 160 to move downward. Driven by the connecting rod 170, the frame 110 moves downward together. During the moving process, the scraper 113 scrapes and cleans the side wall of the sedimentation tank 100, which can effectively solve the caking problem. During sewage discharge, the solenoid valve 351 and the submersible motor 330 are opened. The output shaft of the submersible motor 330 drives the feeding auger 340 to rotate. The precipitated sludge and other impurities will enter the anti-blocking cylinder 310. As the feeding auger 340 continuously rotates, these sludges will be extruded and move downward, and then are discharged to the outside through the sewage pipe 350, effectively avoiding the situation of blockage.
