Description

Technical Field

[0001] The utility model belongs to the technical field of sedimentation tanks, and in particular relates to a sedimentation tank desilting device. Background Art

[0002] A sedimentation tank is a structure that uses sedimentation to remove suspended matter from water. It is a water purifier that uses the natural sedimentation of water or the coagulation and sedimentation effect to remove suspended matter from water. Sedimentation tanks are divided into horizontal sedimentation tanks and vertical sedimentation tanks according to the direction of water flow. The sedimentation effect is determined by the flow rate of water in the sedimentation tank and the residence time of water in the tank. In order to improve the sedimentation effect and reduce the land area, honeycomb inclined tube counter-flow sedimentation tanks, accelerated clarification tanks, pulse clarification tanks, etc. are often used.

[0003] For example, a Chinese patent with publication number CN218540831U discloses a silt removal device for a sewage sedimentation tank. The patent uses a screw, a nut block and a side wall scraper. The screws symmetrically arranged in the transmission belt are driven by a driving motor to rotate simultaneously. The nut block threaded on the outer side of the screw slides, and the fixed rod drives the side wall scraper to slide up and down, which can comprehensively clean the inner wall of the sedimentation tank to avoid sludge residue. The connecting plate, the mounting rod and the pool bottom scraper are connected to the pool bottom scraper slot through the connecting plate fixed on the fixed frame and fixed with the mounting rod for easy disassembly and assembly. The floating mud scraper pushes the sewage scum in the sedimentation tank body to slide, and pushes the scum into the scum pool to facilitate cleaning of the scum. The boss rubber pad, the magnetic block and the fixed rod slide in the boss rubber pad and the groove rubber pad through the fixed rod. The magnetic block and the iron block arranged one by one make the boss rubber pad and the groove rubber pad always engage and connect, avoid sludge from entering the fixed frame, and ensure the normal use of the screw.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when in use, such as: using a pool bottom scraper to scrape the sludge at the bottom of the sedimentation tank, and the length of the pool bottom scraper is fixed, and then after long-term use, the bottom of the pool bottom scraper may frequently rub against the surface of the sedimentation tank, and then the use length of the pool bottom scraper may be worn due to frequent friction. At this time, the worn pool bottom scraper may not be easy to fully fit to the surface of the sedimentation tank, and then the pool bottom scraper may not be easy to completely scrape the sludge at the bottom of the sedimentation tank, which may affect the use effect of the dredging device.

[0006] In view of this, we propose a sedimentation tank desilting device. Utility Model Content

[0007] The purpose of the utility model is to provide a sedimentation tank desilting device to solve the problems raised in the above background technology.

[0008] In view of this, the utility model provides a sedimentation tank desilting device, comprising: a tank body, both sides of the tank body are respectively provided with mounting boxes, and the interior of the tank body is provided with a mounting plate;

[0011] Two sets of inner wall cleaning components, both of which are arranged on one side of the mounting plate and are used to clean the two side walls inside the tank body;

[0012] A side wall cleaning assembly is arranged on one side of the mounting plate and is used for cleaning the inner wall of the pool body.

[0013] In the present technical scheme, the staff uses two first motors, and then the driving shafts of the two first motors rotate simultaneously to drive the two screw rods to rotate, and then under the threaded transmission action of the screw rods and the moving blocks, the two moving blocks drive the connecting plate and the mounting plate to move. At this time, the movement of the mounting plate will drive the protective shell and the scraper bar at the bottom thereof to move, and then the scraper bar will scrape the silt on the bottom surface of the pool body. When the scraper bar is used for a long time, the scraper bar will wear due to friction. At this time, the rebound force of the second spring will push the second connecting column to move downward, and then the downward movement of the second connecting column will drive the protective shell and the scraper bar to move downward, and make the scraper bar always fit the inner bottom surface of the pool body, thereby preventing the scraper bar from affecting the dredging effect due to wear. When the scraper bar is damaged, the staff can pull the scraper bar out from the inside of the second connecting rod, and replace it with a new scraper bar for continued use, thereby preventing the scraper bar from being affected by wear and facilitating the replacement of the scraper bar.

[0016] In the present technical solution, when the mounting plate moves, the two inner wall scrapers will move with the mounting plate, and then the two inner wall scrapers will dredge the two inner walls inside the pool body. When the inner wall scrapers are worn, the rebound force of the first spring will push the inner wall scrapers to move and keep them always in contact with the two inner walls inside the pool body, thereby preventing the inner wall scrapers from being affected by wear and tear, thereby facilitating the dredging of the two inner walls inside the pool body.

[0017] In the above technical solution, further, the side wall cleaning assembly includes:

[0018] A side wall scraper is arranged on one side of the mounting plate, a sleeve is fixedly installed on one side of the mounting plate, a winding wheel is fixedly sleeved on the outer circumferential wall surface of the sleeve driving shaft, a steel cable is wound around the interior of the winding wheel, and one end of the steel cable is fixedly installed on the side wall scraper.

[0019] In this technical solution, when the staff needs to dredge the side wall of the pool body, the staff will move the mounting plate and make the side wall scraper fit the side wall of the pool body, and then the staff will use the sliding sleeve, and the rotation of the driving shaft of the sliding sleeve will drive the winding wheel to rotate. At this time, the winding wheel will reel in the steel cable, and then the side wall scraper will move upward due to the reeling of the steel cable, and then the side wall scraper will dredge the silt on the side wall of the pool body, thereby facilitating the dredging of the side wall of the pool body.

[0020] In the above technical solution, further, a baffle is fixedly installed on one side of the inner wall scraper.

[0021] In the technical solution, the inner wall scraper is prevented from having silt enter between the first connecting rod and the mounting block during the silting process, thereby affecting the use.

[0025] In the technical solution, it is convenient to limit and guide the moving block to prevent the moving block from turning over and deviating when moving.

[0026] The beneficial effects of the utility model are:

[0027] The sedimentation tank dredging device uses two first motors, and then the driving shafts of the two first motors rotate simultaneously to drive the two screw rods to rotate, and then under the threaded transmission action of the screw rods and the moving blocks, the two moving blocks drive the connecting plate and the mounting plate to move, and at this time the movement of the mounting plate will drive the protective shell and the scraper bar at the bottom thereof to move, and then the scraper bar will scrape the silt on the bottom surface of the tank body, and when the scraper bar is used for a long time, the scraper bar will be worn due to friction, and at this time the rebound force of the second spring will push the second connecting column to move downward, and then the downward movement of the second connecting column will drive the protective shell and the scraper bar to move downward, and make the scraper bar always fit the inner bottom surface of the tank body, thereby preventing the scraper bar from affecting the dredging effect due to wear, and when the scraper bar is damaged, the staff can pull the scraper bar out from the inside of the second connecting rod, and replace it with a new scraper bar for continued use, thereby preventing the scraper bar from being affected by wear and facilitating the replacement of the scraper bar.
