Description

Technical Field

[0001] This utility model relates to the field of sedimentation tank technology, specifically to a high-efficiency, high-density sedimentation tank device. Background Technology

[0002] Sedimentation tanks are structures that remove suspended solids from water using sedimentation. They are water purification devices that utilize the natural sedimentation or coagulation sedimentation of water to remove suspended solids. Sedimentation tanks are classified into horizontal sedimentation tanks and vertical sedimentation tanks according to the direction of water flow. The sedimentation effect depends on the water flow rate and the residence time of the water in the sedimentation tank. In order to improve the sedimentation effect and reduce the land area required, honeycomb inclined tube countercurrent sedimentation tanks, accelerated clarification tanks, pulse clarification tanks, etc. are often used. Sedimentation tanks are widely used in wastewater treatment.

[0003] Timely sludge removal is an extremely important task in the operation and management of sedimentation tanks. Sedimentation tanks in wastewater treatment contain a large amount of sludge, most of which is organic matter. If sludge is not removed in time, anaerobic fermentation will occur, causing the sludge to float to the surface. This not only disrupts the normal operation of the sedimentation tank but also deteriorates the quality of the effluent, such as increasing the dissolved BOD value and decreasing the pH value. In the current technology, it is not easy to clean the sediment when discharging from the sedimentation tank. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency, high-density sedimentation tank device to solve the problem that sediment is difficult to clean when discharging from the sedimentation tank.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency, high-density sedimentation tank device, comprising: a tank body, wherein a sedimentation tank is provided on one side of the tank body, a sealing door is installed on the lower side of one end of the sedimentation tank, and a sludge scraping component is provided on the inner side of the sedimentation tank;

[0006] The sludge scraping component includes a movable frame, the left and right ends of which are slidably connected to the inner walls of the left and right sides of the sedimentation tank, respectively. The lower end of the movable frame is slidably connected to a lifting plate through a lifting component. The movable frame slides in the sedimentation tank through a driving component.

[0007] The lower end of the lifting plate is connected to a scraper via a hinge, and a rubber plate is fixedly installed at the lower end of the scraper. A limit plate is fixedly installed on the rear side of the lower end of the lifting plate.

[0008] Furthermore, the lifting plate is U-shaped, and the open end of the lifting plate is slidably sleeved on the lower end of the movable frame.

[0009] Furthermore, an installation groove is provided on one side of the lower end of the scraper, and the upper end of the rubber plate is located in the installation groove. The rubber plate is fixed in the installation groove by a pressure plate.

[0010] Furthermore, the lifting component includes a threaded sleeve II, a threaded rod II, and a limiting rod. The lower end of the threaded rod II is rotatably connected to the inner side of one end of the lifting plate, and the upper end of the threaded rod II moves through the movable frame and is fixedly fitted with a connector.

[0011] Furthermore, the threaded sleeve II is fixedly installed on the upper side of one end of the movable frame, and the inner wall of the threaded sleeve II is threadedly connected to the outer wall of the threaded rod II.

[0012] Furthermore, the lower end of the limiting rod is fixedly installed on the inner side of the other end of the lifting plate, and the upper end of the limiting rod slides through the upper and lower sides of the moving frame.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] This utility model provides, for example Figures 1-7As shown, a high-efficiency, high-density sedimentation tank device includes: a tank body 1, with a sedimentation tank on one side and a coagulation tank and a flocculation zone sequentially arranged on the other side. A sealing door 2 is installed on the lower side of one end of the sedimentation tank. The sealing door 2 can be opened and closed. When opened, the sludge inside the sedimentation tank can be cleaned. A sludge scraping component is provided on the inner side of the sedimentation tank. The sludge scraping component includes a movable frame 6. The left and right ends of the movable frame 6 are slidably connected to the inner walls of the left and right sides of the sedimentation tank, respectively. A lifting plate 10 is slidably connected to the lower end of the movable frame 6 through a lifting component. The lifting plate 10 is U-shaped. The open end of the lifting plate 10 is slidably sleeved on the lower end of the movable frame 6. The lifting plate 10 can slide at the lower end of the movable frame 6. A scraper 16 is rotatably connected to the lower end of the lifting plate 10 through a hinge 20. One end of the hinge 20 is fixed to the side wall of one end of the scraper 16, and the other end of the hinge 20 is fixed to the lower end of the lifting plate 10, allowing the scraper 16 to rotate at the lower end of the lifting plate 10.

[0028] A limiting plate 15 is fixedly installed on the lower rear side of the lifting plate 10. The limiting plate 15 is located at the rear end of the scraper 16. When the moving frame 6 moves forward with the scraper 16, the limiting plate 15 limits the scraper 16. The scraper 16 is vertically located at the lower end of the lifting plate 10, so that the sludge at the bottom of the sedimentation tank can be scraped out by the scraper 16. When the moving frame 6 moves backward with the scraper 16, the scraper 16 rotates to one side through the hinge 20, so that the sludge will not be scraped to the inside of the sedimentation tank.

[0029] A rubber plate 18 is fixedly installed at the lower end of the scraper 16. An installation groove 17 is provided on one side of the lower end of the scraper 16. The upper end of the rubber plate 18 is located in the installation groove 17, and the lower end is located at the lower end of the scraper 16. The rubber plate 18 is fixed in the installation groove 17 by a pressure plate 19. The pressure plate 19 is located on the outer side of the upper end of the rubber plate 18. The bolt passes through the pressure plate 19 and the rubber plate 18 and is threaded to the side wall of the installation groove 17, thereby fixing the rubber plate 18. The lower end of the rubber plate 18 contacts the bottom end of the sedimentation tank to scrape off the sludge at the bottom.

[0030] Specifically, when it is necessary to clean the sludge at the bottom of the sedimentation tank, the moving frame 6 is driven forward, and the limiting plate 15 limits the scraper 16. The scraper 16 is vertically located at the lower end of the lifting plate 10, and the lower end of the rubber plate 18 contacts the bottom of the sedimentation tank, so that the sludge at the bottom of the sedimentation tank can be scraped out. When the moving frame 6 moves to the rear with the scraper 16, the scraper 16 rotates to one side through the hinge 20, and the rubber plate 18 will not scrape the sludge to the inside of the sedimentation tank.

[0031] like Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, in some embodiments, the movable frame 6 slides in the sedimentation tank via a driving component. The lifting component includes a threaded sleeve 11, a threaded rod 12, and a limiting rod 14. The lower end of the threaded rod 12 is rotatably connected to the inner side of one end of the lifting plate 10. The upper end of the threaded rod 12 moves through the movable frame 6 and is fixedly fitted with a connector 13. The upper end of the connector 13 is provided with an internal hexagonal socket. Workers climb to the upper end of the sedimentation tank via a ladder and insert a long rod with an internal hexagonal plug into the connector 13, thereby driving the connector 13 and the threaded rod 12 to rotate via the long rod.

[0032] The threaded sleeve 11 is fixedly installed on the upper side of one end of the movable frame 6. The inner wall of the threaded sleeve 11 is threadedly connected to the outer wall of the threaded rod 12. The lower end of the limiting rod 14 is fixedly installed on the inner side of the other end of the lifting plate 10. The upper end of the limiting rod 14 slides through the upper and lower sides of the movable frame 6. More specifically, when there is a lot of sludge at the bottom of the sedimentation tank, the resistance generated by the sludge is large. When scraping the sludge, the scraper 16 and the rubber plate 18 may be damaged or the drive component may stop for protection. By rotating the threaded rod 12, the height of the scraper 16 and the rubber plate 18 in the vertical direction can be adjusted, and the sludge can be scraped away layer by layer.

[0033] like Figure 2 and Figure 3 As shown, in some embodiments, the driving component includes a guide rod 4, a threaded rod 5, a threaded sleeve 7, and a guide sleeve 8. The guide rod 4 is fixedly installed on the inner wall of one side of the sedimentation tank, and the threaded rod 5 is rotatably connected to the inner wall of the other side of the sedimentation tank. The threaded sleeve 7 and the guide sleeve 8 are respectively fixedly installed on the left and right side walls of the movable frame 6. The guide rod 4 slides through the guide sleeve 8, and the threaded rod 5 passes through the threaded sleeve 7 and is threadedly connected to the inner wall of the threaded sleeve 7. Guide rods 9 are slidably connected to the lower left and right sides of the movable frame 6. The front and rear ends of the guide rods 9 are fixedly connected to the front and rear inner walls of the sedimentation tank, respectively. A motor 3 is fixedly installed on the side wall of the end. The output end of the motor 3 is fixedly connected to one end of the threaded rod 5. The motor 3 is a servo motor, which can drive the threaded rod 5 to rotate in both directions, thereby driving the threaded sleeve 7 to move back and forth at the upper end of the threaded rod 5. This causes the moving frame 6, scraper 16, and rubber plate 18 to move synchronously. More specifically, when it is necessary to scrape the sludge at the bottom of the sedimentation tank, the motor 3 is turned on to drive the threaded rod 5 to rotate. The threaded rod 5 drives the moving frame 6, scraper 16, and rubber plate 18 to move. The rubber plate 18 scrapes the sludge to one side of the sealing door 2. By opening the sealing door 2, the sludge can be cleaned.

[0034] Working principle:

[0035] Step 1: When it is necessary to clean the sludge at the bottom of the sedimentation tank, the moving frame 6 is driven forward by the driving component, the limiting plate 15 limits the scraper 16, the scraper 16 is vertically located at the lower end of the lifting plate 10, and the lower end of the rubber plate 18 contacts the bottom of the sedimentation tank, so that the sludge at the bottom of the sedimentation tank can be scraped out.

[0036] Step 2: When the moving frame 6 moves backward with the scraper 16, the scraper 16 rotates to one side through the hinge 20. The rubber plate 18 will not scrape the sludge to the inside of the sedimentation tank. Repeating this several times will clean the sludge at the bottom of the sedimentation tank.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
