Description

Technical Field

[0001] The invention relates to the technical field of sludge treatment, in particular to a sludge collection mechanism based on sewage treatment. Background Art

[0002] Sludge is an inevitable product of sewage treatment plants and sewage stations. Sludge that has not been properly treated and disposed of will directly cause secondary pollution to water bodies and the atmosphere after entering the environment, and will also pose a serious threat to the ecological environment and human activities. In addition, the sludge contains many impurities, which is not easy to be treated uniformly and needs to be separated. When the existing sludge treatment equipment is in use, due to the high viscosity of the sludge, it is easy to clog the internal machinery, affecting the separation efficiency, thereby reducing the efficiency of sludge collection. In addition, the wastewater discharged from the sludge often carries a lot of large slag. These slags directly enter the treatment box and easily cause blockage inside the treatment box, causing the staff to frequently clean the blockage, which slows down the efficiency of wastewater collection. Therefore, a sludge collection mechanism based on sewage treatment is invented to solve the above problems. Summary of the invention

[0015] Preferably, the top of the elliptical plate is movably connected to a movable plate, the top of the movable plate is connected to a hollow shell, the hollow parts at both ends of the hollow shell are correspondingly connected to the inlet and the outlet, and the hollow part at the bottom of the hollow shell is fixedly connected to the first filter plate and the second filter plate.

[0016] Preferably, the movable plate includes a curved soft plate, two grippers are fixedly connected to the rear side of the curved soft plate, one end of a short block is fixedly connected to both sides of the center of the two grippers, the other ends of the two short blocks are movably connected to movable shafts, the centers of the two movable shafts are movably connected to support blocks, and the top of the support block is fixedly connected to the inner wall of the hollow shell.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides a sludge collection mechanism based on sewage treatment, which has the following beneficial effects:

[0019] 1. The sludge collection mechanism based on sewage treatment sets a motor at one end of the top of the bottom plate, so that the motor generates electricity to drive the bandage connected to the output shaft to rotate. The rotating bandage will drive the connected rotating device to rotate, and the sewage poured into the inlet will be squeezed by the rotating device and the movable device to separate the sludge and sewage generated in the wastewater treatment process. If the sewage and sewage are not treated properly, it may cause secondary pollution to the water environment, so it is very necessary to separate the sewage and the sludge.

[0020] 2. The sludge collection mechanism based on sewage treatment is respectively arranged at the two ends of the treatment box through the inlet and the outlet. The sludge in the sewage can be separated by the cooperation of the rotating device in the middle and the movable device. Desludge can reduce the sludge concentration, reduce the sludge output, and reduce the treatment cost. The separated sewage will flow out directly from the bottom, and the sludge will be discharged through the outlet. In addition, there are two brackets fixedly connected at the bottom of the outlet to increase the support strength. At the same time, separating sewage from sludge is not only to protect the water ecology and reduce the negative impact on the environment, but also to achieve the effective utilization and circulation of resources, in line with the requirements of environmental protection laws and regulations and the goal of sustainable development.

[0021] 3. The sludge collection mechanism based on sewage treatment can use the rotation of the bandage to drive the rotating column to move by connecting the outer surface of the first rotating shaft with the top of the bandage. The rotating column and the first gear are fixedly connected, so when the first gear rotates, it will drive the second gear meshingly connected to the outer surface to rotate together, so that the second gear moves greatly in the groove at the front end of the round shell, and also drives the movable plate in the movable device connected to the top of the second rotating shaft to swing, so that the sludge in the wastewater can be squeezed and separated, reducing the solid content, volume and weight in the wastewater, which can not only reduce the cost of wastewater treatment, but also reduce pollution to the water environment and the environment.

[0022] 4. The sludge collection mechanism based on sewage treatment can drive the movable plate between the two connecting blocks to swing by connecting the connecting block with the second rotating shaft. During the swinging process, the two balls will increase the flexibility of rotation. In addition, the movable plate is curved and fits the inner wall of the hollow shell. Therefore, when the sewage enters the hollow part of one side of the hollow shell, it will first be filtered and screened at the hollow part of the movable plate for the first time, and the sludge will be blocked at the outlet on the other side of the hollow shell. Excess water will flow out along the hollow part of the movable plate. After reaching a certain weight, the movable plate will shift to the discharge port to discharge the sludge. At the same time, two first filter plates and the second filter plates are connected at the bottom of the hollow shell, which can filter the missed sludge particles for a second time. If the particles are not disposed of in time, they will easily damage other equipment when entering the subsequent treatment facilities. At this time, removing the particulate matter after desludging can reduce the equipment damage rate.

[0023] 5. The sludge collection mechanism based on sewage treatment, by setting the curved soft plate and the gripper together, can utilize the movement of the short blocks on both sides of the gripper to drive the curved soft plate to move up and down. The movable shaft movably connected between the support block and the short block, in addition to connecting the two devices together, can also drive the curved soft plate to stretch and bend upward. The curved soft plate that moves back and forth can now scrape off the residue attached to the inner wall of the hollow shell, solving the need for subsequent manual cleaning.

The top end of the second rotating shaft 36 is provided with a movable device 4. By connecting the outer surface of the first rotating shaft 32 to the top end of the bandage 23, the rotating column 33 can be driven to move by the rotation of the bandage 23. The rotating column 33 and the first gear 34 are fixedly connected. Therefore, when the first gear 34 rotates, it will drive the second gear 35 meshingly connected to the outer surface to rotate together, so that the second gear 35 moves greatly at the front end groove of the shell 37, and also drives the movable plate 44 in the movable device 4 connected to the top end of the second rotating shaft 36 to swing, so that the sludge in the wastewater can be squeezed out and separated, and the solid content, volume and weight in the wastewater can be reduced, which can not only reduce the cost of wastewater treatment, but also reduce the pollution to the water environment and the environment. The top end of the second rotating shaft 36 is fixedly connected to both ends of the movable device 4.

[0040] The movable device 4 includes two connecting blocks 41, and the bottom ends of the two connecting blocks 41 are fixedly connected to the top of the second rotating shaft 36, the tops of the two connecting blocks 41 are provided with balls 42, and the tops of the two connecting blocks 41 are movably connected to the two sides of the balls 42, the inner sides of the two balls 42 are provided with elliptical plates 43, and the inner sides of the two balls 42 are fixedly connected to the two ends of the elliptical plates 43, a movable plate 44 is provided on the top of the elliptical plate 43, and the top of the elliptical plate 43 is movably connected to the bottom of the movable plate 44, a hollow shell 45 is connected to the top of the movable plate 44, the hollow parts at both ends of the hollow shell 45 are correspondingly connected to the inlet 25 and the outlet 26, the hollow part of the bottom of the hollow shell 45 is provided with a first filter plate 46 and a second filter plate 47, and by setting the connecting block 41 to be connected to the second rotating shaft 36, the two connecting blocks can be driven The movable plate 44 in the middle of the connecting block 41 swings. During the swinging process, the two balls 42 increase the flexibility of the rotation. In addition, the movable plate 44 is curved and fits the inner wall of the hollow shell 45. Therefore, when the sewage enters the hollow part of one side of the hollow shell 45, it will first be filtered and screened at the hollow part of the movable plate 44, and the sludge will be blocked at the outlet of the other side of the hollow shell 45. The excess water will flow out along the hollow part of the movable plate 44. After reaching a certain weight, the movable plate 44 will shift to the discharge port 26 to discharge the sludge. At the same time, two first filter plates 46 and a second filter plate 47 are connected at the bottom of the hollow shell 45, which can filter the missed sludge particles for a second time. If the particles are not disposed of in time, they will easily damage other equipment when entering the subsequent treatment facilities. At this time, removing the particles after the desludging process can reduce the equipment damage rate.

By setting the curved soft board 441 and the gripper 442 together, the movement of the short blocks 443 on both sides of the gripper 442 can be used to drive the curved soft board 441 to move up and down. The movable shaft 444 movably connected between the support block 445 and the short block 443 can not only connect the two devices together, but also drive the curved soft board 441 to stretch and bend upward. The curved soft board 441 that moves back and forth can scrape off the residue attached to the inner wall of the hollow shell 45, solving the need for manual cleaning later.
