Description

Technical Field

[0001] The utility model relates to the technical field of sedimentation tank sludge treatment, in particular to a sedimentation tank sludge cleaning device. Background Art

[0002] A large amount of wastewater will be discharged during the production of concrete or when concrete waste is treated. These wastewaters cannot be discharged directly, but need to be discharged after sedimentation in a sedimentation tank. A sedimentation tank is a device that performs preliminary sludge separation and treatment by static sedimentation. After long-term use, a large amount of sludge will accumulate at the bottom of the sedimentation tank. When the sludge exceeds the volume of the sedimentation tank, the sludge height in the tank will increase, seriously affecting the sedimentation effect and treatment efficiency. Therefore, it is necessary to regularly treat the sludge in the sedimentation tank. At present, most sedimentation tanks are not convenient for recycling and cleaning sludge, resulting in waste of internal space of the sedimentation tank and reduced sedimentation efficiency. The existing technology generally uses a manually waving scraper to remove sludge, which has the following shortcomings: the sludge attached to the wall of the sedimentation tank cannot be cleaned during dredging, which affects the effect and quality of dredging, and there is a lack of a breaking component. When the sludge is heavy, it will be difficult to push the scraper, which increases the cost of dredging. Utility Model Content

[0003] The utility model aims to provide a sedimentation tank sludge cleaning device, which can solve the above technical problems, is not easy to be blocked, has simple dredging, good dredging quality and low cost.

[0004] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a sedimentation tank sludge cleaning device, including a sedimentation tank, a screw rod is rotatably connected to one side of the top of the sedimentation tank, a guide rod is provided on the side of the top of the sedimentation tank opposite to the screw rod, a nut one and a nut two are threadedly connected to the screw rod, a cross bar one is fixedly provided on the nut one, a cross bar two is fixedly provided on the nut two, the cross bar one and the cross bar two are slidably connected to the guide rod, a hand wheel is rotatably connected to the cross bar two, a vertical rod is connected to the inner thread of the hand wheel, the vertical rod passes through the cross bar two and a triangular prism-shaped scraper is fixedly provided at the bottom, an edge of the scraper is opposite to the bottom of the sedimentation tank, a scraper plate is fixedly provided on the side wall of the scraper, the scraper plate abuts against the side wall of the sedimentation tank, the cross bar one is located in front of the cross bar two and a breaking component is provided on the cross bar one.

[0005] By adopting the above technical scheme, the hand wheel is turned to drive the vertical rod to move downward until the bottom edge of the scraper piece abuts against the sedimentation tank, and the screw rod is turned to drive nut one and nut two to slide along the guide rod. When nut one moves, it drives cross bar one and the breaking up assembly to move. The breaking up assembly breaks up the sludge to make the particles of different sizes uniform to prevent blockage; when nut two moves, it drives cross bar two to move. When cross bar two moves, it drives the triangular prism-shaped scraper piece to move along the bottom of the sedimentation tank and the scraper plate to move along the side wall of the sedimentation tank. The edges of the scraper piece opposite to the sedimentation tank scrape up and push forward the sludge at the bottom of the sedimentation tank, and the scraper plate scrapes up and pushes forward the sludge on the side wall of the sedimentation tank, thereby realizing dredging of the bottom and side walls of the sedimentation tank. It has the advantages and effects of thorough dredging, good dredging effect and quality, simple structure and low cost.

[0006] The utility model is further configured as follows: the scattering component includes a rotating shaft rotatably connected to a cross bar, the rotating shaft is provided with multiple and evenly spaced, a plurality of scattering blades are fixedly connected to the bottom of the rotating shaft, a gear is fixedly provided on the top, the plurality of gears are meshingly connected, a driving motor is rotatably fixedly provided on the top of the cross bar, and the driving motor is used to drive any gear to rotate.

[0007] By adopting the above technical solution, the driving motor drives the gear to rotate, and the gear drives the rotating shaft and adjacent gears connected thereto to rotate, thereby driving the breaking up blades connected to the rotating shaft to rotate, and the rotating shaft and breaking up blades connected to the adjacent gears also rotate with the adjacent gears, and all the breaking up blades rotate at high speed to break up large pieces of material or particles in the sludge, making it convenient for the scraper and the scraper to scrape them away, thereby avoiding the scraper and the scraper from getting stuck and being unable to operate during operation.

[0008] The utility model is further configured as follows: the mud scraper plate is vertically connected to the mud scraper member.

[0009] By adopting the above technical solution, the scraper blade and the scraper member are vertically connected, which can avoid the angle between the scraper blade and the scraper member being too small, causing the connection to be blocked by silt that is difficult to clean, which will affect the dredging efficiency for a long time.

[0010] The utility model is further configured as follows: an inclined mud guide plate is provided at the tail end of the sedimentation tank.

[0011] By adopting the above technical solution, the scraper blade and the scraper piece push the sludge in the sedimentation tank onto the mud guide plate, and discharge it from the sedimentation tank through the mud guide plate.

[0012] The utility model is further configured as follows: a baffle is provided below the crossbar, and the baffle is located above the scattering blades.

[0013] By adopting the above technical solution, the baffle plate prevents the sludge from being splashed everywhere and difficult to clean up when the sludge is scattered by the blades at high speed, and the baffle plate is provided to block the splashing sludge.

[0014] The utility model is further configured as follows: four scattering blades are provided and the four scattering blades are evenly arranged at the bottom of the rotating shaft.

[0015] By adopting the above technical solution, the four breaking blades rotate at high speed along with the rotating shaft at the bottom of the rotating shaft, and the large pieces of matter or particles in the sludge are fully broken up, and the breaking effect is good.

[0016] The utility model is further configured such that the length of the scattering blades is smaller than the distance between the nut 1 and the nut 2 (anti-collision).

[0017] By adopting the above technical solution, it is avoided that the scattering blade is too long and hits the scraper plate or the scraper member, causing the scattering blade to be damaged and unable to work normally.

[0018] The utility model is further configured as follows: the bottom of the scraper plate is at the same height as the bottom of the scraper element.

[0019] By adopting the above technical solution, the problem of residual sludge in the sedimentation tank not being completely cleaned due to dead corners at the bottom of the scraper can be avoided, and the cleaning is more thorough.

[0020] The utility model is further configured as follows: it also includes a bidirectional motor, and the bidirectional motor is used to drive the screw rod to rotate.

[0021] By adopting the above technical solution, the bidirectional motor drives the screw rod to move forward / reversely. When the screw rod rotates forward, it drives nut 1 and nut 2 to move forward along the guide rod, driving the scraper plate and scraper to clean the silt. Then, the hand wheel is rotated to drive the vertical rod to rise, and then the screw rod is rotated in the reverse direction to drive nut 1 and nut 2 to move backward along the guide rod to their original position and wait for the next silt removal.

[0022] The utility model is further configured as follows: the vertical rod is located in the middle of the mud scraper.

[0023] By adopting the above technical solution, the hand wheel rotates to drive the vertical rod to move up and down. The vertical rod is located in the middle of the scraper. When the hand wheel applies pressure to the vertical rod, the scraper located in the middle of the vertical rod is evenly stressed, and the scraping is more even.

[0024] The beneficial effects of the utility model are as follows: by arranging a triangular prism-shaped scraper and fixing scraper plates in the middle of both sides of the scraper, the hand wheel is rotated to drive the vertical rod to move downward until the bottom edge of the scraper abuts against the sedimentation tank, and the side wall of the scraper plate abuts against the side wall of the sedimentation tank, and the screw rod is rotated to drive nut one and nut two to slide along the guide rod. When nut one moves, it drives cross bar one and the scattering assembly to move. The scattering assembly scatters the sludge to make the particles of different sizes uniform to prevent blockage. When nut two moves, it drives cross bar two to move. When cross bar two moves, it drives the triangular prism-shaped scraper to move along the bottom of the sedimentation tank and the scraper plate to move along the side wall of the sedimentation tank. The edges of the scraper and the sedimentation tank relative to each other scrape the sludge at the bottom of the sedimentation tank and push it forward, and the scraper plate scrapes the sludge on the side wall of the sedimentation tank and pushes it forward, thereby realizing dredging of the side wall of the bottom machine of the sedimentation tank, and has the advantages and effects of thorough dredging, good dredging effect and quality.
