[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] As shown in the figure, a buffer tank for feeding a belt filter includes a tank body 1. Inside the tank body 1, there is a spray unit and a cleaning unit. A vertically mounted rotating shaft 2 is installed inside the tank body 1, connecting the cleaning unit and the spray unit. The spray unit is located above the cleaning unit. An inlet 11 is located on the upper side wall of the tank body 1, and an outlet 12 is located on one side of the bottom of the tank body 1. In this embodiment, both the outlet 12 and the inlet 11 are equipped with switching valves. In this embodiment, the rotating shaft 2 inside the tank body 1, along with the spray unit and the cleaning unit, allows the spray unit and the cleaning unit to rotate synchronously when the shaft 2 rotates. When cleaning of the inner wall of the tank body 1 is required, the spray unit sprays cleaning water, performing cleaning while rotating, resulting in a more thorough and efficient cleaning of the inner wall of the tank body 1. When cleaning water is not needed, the rotation of the cleaning unit also agitates the material inside the tank body 1, facilitating the material's flow out from the outlet 12.

[0029] The cleaning unit includes multiple vertically arranged cleaning frames 5, which are uniformly welded and fixed to the circumferential surface of the rotating shaft 2. In this embodiment, the number of cleaning frames 5 is 3-6.

[0030] The tank 1 has an opening at the top, and the upper part of the side wall of the tank 1 is a cylindrical structure, the lower part is an inverted conical structure, and the bottom is a horizontal structure. The cleaning frame 5 includes a first horizontal section 51, a second horizontal section 52, a vertical section 53, an inclined section 54, and a third horizontal section 55. The outer ends of the first horizontal section 51 and the second horizontal section 52 are respectively connected to the two ends of the vertical section 53. The first horizontal section 51 is located above the second horizontal section 52, and the third horizontal section 55 is located below the second horizontal section 52. The two ends of the inclined section 54 are respectively connected to the lower end of the vertical section 53 and the outer end of the third horizontal section 55. The inner ends of the first horizontal section 51, the second horizontal section 52, and the third horizontal section 55 are all fixed to the rotating shaft 2. The vertical section 53 is attached to the upper part of the inner wall of the tank 1, the inclined section 54 is attached to the lower part of the inner wall of the tank 1, and the third horizontal section 55 is attached to the bottom of the inner wall of the tank 1. In this embodiment, the cleaning frame 5 is an integrally formed structure, and the first horizontal section 51, the second horizontal section 52 and the third horizontal section 55 are welded and fixed on the rotating shaft 2. In this embodiment, the lower part of the tank body 1 is set with an inverted cone-shaped structure, which is conducive to feeding and discharging. The second horizontal section 52 and the third horizontal section 55 on the cleaning frame 5 are conducive to fully stirring the material in the tank body 1. The outer wall of the cleaning frame 5 is set in close contact with the inside of the tank body 1. When the rotating shaft 2 drives it to rotate, it can better clean the residues attached to the inner wall of the tank body 1.

[0031] The spray unit includes a horizontally arranged spray pipe 3, with multiple nozzles 4 evenly distributed at the bottom of the spray pipe 3. The spray pipe 3 and the cleaning frame 5 are staggered to reduce the impact of the cleaning frame 5 position on the cleaning water sprayed from the nozzles 4. A water channel 21 is formed at the top of the rotating shaft 2, and horizontally arranged spray pipes 3 connected to the water channel 21 are welded to both sides of the top of the rotating shaft 2. A water inlet pipe 7 is connected to the upper side of the water channel 21. In this embodiment, the spray pipe 3 and the rotating shaft 2 are welded and fixed together.

[0032] A cover 6 is fixedly attached to the top opening of the tank body 1. A through hole 61 is opened in the middle of the cover 6, and a water inlet pipe 7 is fixedly connected to the through hole 61, with its bottom end passing through the through hole 61 and inserted into the opening of the water passage 21. In this embodiment, the water inlet pipe 7 and the water passage 21 are fitted with a clearance, which allows the rotating shaft 2 to drive the spray pipe 3 to rotate synchronously without being constrained by the water inlet pipe 7, and allows cleaning water to be smoothly delivered to the spray pipe 3 through the water inlet pipe 7. In this embodiment, a connecting edge is provided horizontally outward on the top of the tank body 1, and the edge of the cover 6 is fixed to the connecting edge by multiple bolt and nut pairs (not shown in the figure). A switch valve is also provided on the water inlet pipe 7.

[0033] A motor 9 is fixedly connected to the bottom of the tank body 1. The output shaft of the motor 9 is fixedly connected to the bottom end of the rotating shaft 2. An annular connecting boss 62 is fixedly connected to the bottom of the cover body 6 at the top end of the rotating shaft 2. The top end of the rotating shaft 2 is inserted into the connecting boss 62 and connected to the connecting boss 62 through a bearing 8. In this embodiment, the rotating shaft 2 is driven to rotate by the motor 9, which in turn drives the cleaning unit and the spraying unit to rotate, thereby scraping and cleaning the inner wall of the tank body 1. In this embodiment, an annular connecting boss 62 is fixedly connected to the bottom of the cover body 6 at the top end of the rotating shaft 2. The top end of the rotating shaft 2 is inserted into the connecting boss 62 and connected to the connecting boss 62 through a bearing 8.

[0034] The nozzles 4 on the spray pipe 3 are all tilted downwards, and the nozzles 4 on both sides of the rotating shaft 2 are tilted in opposite directions so that the water from the nozzles 4 can be sprayed onto the inner wall of the tank 1. In this embodiment, the tilt angle of the nozzles 4 is 15-45 degrees.

[0035] A scraper is fixed to the side of the cleaning frame 5 facing the inner wall of the tank 1, and a rubber scraper is fixed to the outside of the scraper to facilitate cleaning the inner wall of the tank 1.

[0036] Multiple support columns 10 are evenly fixed to the outer wall of the tank 1. Each support column 10 has a pad 101 fixed to its bottom to support the tank 1.

[0037] The feed inlet 11 is positioned lower than the nozzle 4 to prevent the nozzle 4 from being blocked when the material enters the tank 1 from the feed inlet 11.

[0038] The working process of this embodiment is as follows:

[0039] Material enters the tank 1 through the feed inlet 11. The motor 9 is started to drive the rotating shaft 2 to rotate, which in turn drives the cleaning frame 5 and the spray pipe 3 to rotate synchronously. When it is not necessary to use cleaning water to rinse the inner wall of the tank 1, the inner wall of the tank 1 is only scraped and cleaned by the cleaning frame 5. At the same time, the cleaning frame 5 also plays a stirring role. When it is necessary to use cleaning water to rinse the inner wall of the tank 1, the cleaning water is drawn from the water source to the water inlet pipe 7 by the water pump, and then enters the spray pipe 3 through the water tank 21. Through the pressurization of the water pump, the water is sprayed out from the nozzle 4 toward the inner wall of the tank 1. The rotation of the spray pipe 3 achieves a comprehensive rinsing of the inner wall of the tank 1.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
