DETAILED DESCRIPTION
[0015] The following is combined with Figure 1-4 This application is described in further detail.
[0016] The present application embodiment discloses a sedimentation tank for sewage treatment, referring to Figure 1-4The two fixing frames 2 are respectively located on both sides of the sedimentation tank body 1. The top and bottom ends of the two fixing frames 2 are each provided with three mounting members 3 for fixing the fixing frames 2 on both sides of the sedimentation tank body 1. The twelve mounting members 3 are each composed of a mounting block 31 and a bolt 32. Six mounting blocks 31 are welded to one of the fixing frames 2, and the other six mounting blocks 31 are welded to the other fixing frame 2. The twelve bolts 32 are threadedly penetrated through the twelve mounting blocks 31, and the twelve bolts 32 are threadedly connected to the sedimentation tank body 1, so that the two fixing frames 2 are respectively fixedly installed on both sides of the sedimentation tank body 1. The internal movement of the sedimentation tank body 1 is provided with a push plate 41, and the two sides of the push plate 41 are connected to the two sides of the sedimentation tank body 1. The inner walls of the two fixed frames 2 are fitted together, the bottom end surface of the push plate 41 is fitted with the inner bottom wall of the sedimentation tank body 1, and a connecting rod 42 is welded to the top of the push plate 41. The length of the connecting rod 42 is longer than the width of the sedimentation tank body 1. The insides of the two fixed frames 2 are slidably connected with sliding blocks 43. The bottom end surfaces of the two sliding blocks 43 are respectively fitted with the inner bottom walls of the two fixed frames 2, and the inner top walls of the two sliding blocks 43 are fitted with the inner top walls of the two fixed frames 2. One end of the two fixed frames 2 is provided with a driving member 5 for driving the two sliding blocks 43 to slide. The two driving members 5 are composed of a forward and reverse motor 51 and a threaded rod 52. The two forward and reverse motors 51 are respectively fixedly installed at one end of the fixed frame 2. The two forward and reverse motors 51 are electrically connected to the external power supply through an external switch. Then, the power shafts of the two forward and reverse motors 51 rotate and penetrate the two fixed frames 2, and the two threaded rods 52 respectively thread through the two sliding blocks 43. The threads of the two threaded rods 52 are opened in the same direction. One end of the two threaded rods 52 is respectively welded to the end of the power shaft of the two forward and reverse motors 51, and the other end of the two threaded rods 52 rotates and penetrates one of the inner side walls of the two fixed frames 2. When the two forward and reverse motors 51 are started by an external switch and the power shafts of the two forward and reverse motors 51 drive the two threaded rods 52 to rotate in the same direction, the two threaded rods 52 drive the two sliding blocks 43 to slide inside the two fixed frames 2. The inner bottom walls of the two sliding blocks 43 are fixedly installed with hydraulic cylinders 44. The two hydraulic cylinders 44 are connected to one of the oil pipes of the external device. The external reversing valve is connected to the external oil pump through another external oil pipe. The external oil pump is installed in the external oil tank. The output ends of the two hydraulic cylinders 44 are respectively movable through the two sliding blocks 43. The output ends of the two hydraulic cylinders 44 are respectively fixedly connected to the two ends of the bottom of the connecting rod 42. The two sliding blocks 43 drive the connecting rod 42 to slide through the output ends of the two hydraulic cylinders 44 during the sliding process. The connecting rod 42 drives the push plate 41 to slide inside the sedimentation tank body 1, thereby completely scraping away the impurities and sludge precipitated at the bottom of the sedimentation tank body 1. After that, after the push plate 41 moves to one end inside the sedimentation tank body 1 and one end of the bottom of the push plate 41 conflicts with the other inner wall of the sedimentation tank body 1, the external reversing valve is opened at this time.The external oil pump draws the oil from the external oil tank and discharges it to the inside of the two hydraulic cylinders 44 through two external oil pipes and external reversing valves. The output ends of the two hydraulic cylinders 44 extend under the oil pressure of the oil inside the two hydraulic cylinders 44, and push the connecting rod 42 to drive the push plate 41 to rise, so that the impurities and sludge inside the sedimentation tank body 1 can be raised.
[0017] Reference Figure 1 and Figure 2 A drainage hole is provided at the bottom end of one of the inner side walls of the sedimentation tank body 1, and a drainage pipe 6 with a manual valve is fixedly passed through the interior of the drainage hole. The sewage precipitated in the sedimentation tank body 1 can be discharged by opening the valve of the drainage pipe 6.
[0018] The implementation principle of a sedimentation tank for sewage treatment in the embodiment of the present application is as follows: when in use, two forward and reverse motors 51 are started by an external switch, and when the power shafts of the two forward and reverse motors 51 drive the two threaded rods 52 to rotate in the same direction, the two threaded rods 52 drive the two sliding blocks 43 to slide inside the two fixed frames 2, and when the two sliding blocks 43 slide, the output ends of the two hydraulic cylinders 44 drive the connecting rods 42 to slide, and the connecting rods 42 drive the push plates 41 to slide inside the sedimentation tank body 1, thereby the sedimentation at the bottom of the sedimentation tank body 1 is moved. The impurities and sludge are completely scraped away, and then the push plate 41 moves to one end of the inside of the sedimentation tank body 1 and one end of the bottom of the push plate 41 contacts the other inner wall of the sedimentation tank body 1. At this time, the external reversing valve is opened, and the external oil pump draws the oil in the external oil tank and discharges it to the inside of the two hydraulic cylinders 44 through two external oil pipes and the external reversing valve. The output ends of the two hydraulic cylinders 44 extend out under the oil pressure of the oil inside the two hydraulic cylinders 44, and push the connecting rod 42 to drive the push plate 41 to rise, so that the impurities and sludge inside the sedimentation tank body 1 can be raised.
