Description

Technical Field

[0001] This utility model relates to the technical field of beet processing equipment, specifically to a conveyor belt beet residue and soil cleaning mechanism. Background Technology

[0002] In the sugar-making process of beets, after washing and pre-treatment, the beets need to be shredded by a shredder to facilitate the extraction of sugar. After pressing, the beets produce beet pulp, also known as sugarcane residue. This residue needs to be transferred to a centralized processing area via a conveyor belt. During this process, some residue adheres to the surface of the conveyor belt. Because the residue also contains a small amount of sugar, it is difficult to remove from the conveyor belt surface if left untreated for a long time. Cleaning the conveyor belt requires rinsing, which often leaves water stains underneath. The accumulated residue mixes with the rinsing water, affecting the factory environment. Utility Model Content:

[0003] To address the shortcomings of existing technologies, this utility model provides a conveyor belt vegetable scrap and mud cleaning mechanism. By installing a cleaning mechanism under the conveyor belt, water and vegetable scrap are recycled separately while the conveyor belt is being cleaned. The recycled vegetable scrap is separated from the water, avoiding impact on the factory environment. The recycled cleaning water is reused, improving water resource utilization and reducing cleaning water consumption.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

Detailed implementation method:

[0023] like Figure 1-4As shown, a vegetable scrap and soil cleaning mechanism for a conveyor belt 1 is mainly installed below the conveyor belt 1 and relies on the conveyor belt 1. The conveyor belt 1 is inclined and conveys upwards; the water collection trough 9 is arranged parallel to the conveyor belt 1. A slag guide trough 7 is inclinedly provided below the discharge end of the conveyor belt 1; a discharge port 2 is mounted on the top of the slag guide trough 7; the discharge port 2 includes an outer cover and a discharge trough, and a discharge trough perpendicular to the conveying direction of the conveyor belt 1 is provided below the outer cover to change the discharge direction, ensuring that the material is discharged along the outer cover while avoiding splashing during the rinsing process. A guide rod 10 is fixed at the bottom of the slag guide trough 7; a limiting plate 20 is provided in the water collection trough 9 at the position corresponding to the guide rod 10; a first pressure spring 11 is sleeved on the guide rod 10 above the limiting plate 20; when a relatively hard object is attached to the conveyor belt 1, the scraper plate 3 is prevented from making hard contact; if the scraper plate 3 is subjected to excessive force, it can retract along the guide rod 10. Correspondingly, a support rod 16 is fixed on the inner side of the water collection trough 9 below the discharge position of the slag chute 8; sleeve plates 17 are provided on both sides of the water collection trough 9 at the positions corresponding to the support rod 16, and the sleeve plates 17 have through holes. The sleeve plates 17 can move up and down along the support rod 16. A second pressure spring 18 is sleeved on the support rod 16 below the sleeve plate 17. A baffle is fixed on the support rod 16 below the second pressure spring 18, and the top of the support rod has a stopper for blocking the spring. The slag chute 8 can move up and down to compress. One end of the water collection trough 9 corresponding to the discharge position of the slag chute is closed. A scraper plate 3 is rotatably provided on the inner side of the slag guide trough 7. The scraper plate 3 is driven by a rotating mechanism 4. The rotating mechanism 4 can adjust the angle of the scraper plate 3 to adapt to the inclination angle of the conveyor belt 1. A spray pipe 5 is fixed to the back of the slag guide trough 7; the spray pipe 5 is connected to the water source, and the spray pipe 5 is equipped with flushing nozzles 6 arranged at the position of the pipe body of the scraper plate 3; the flushing nozzles 6 are inserted into the slag guide trough 7 and sprayed towards the scraping position of the scraper plate 3 to rinse; after the scraper plate 3 scrapes up the slag, some vegetable scrap will not fall off directly, and rinsing can effectively wash away the vegetable scrap and ensure that the conveyor belt 1 is thoroughly cleaned.

[0024] like Figure 1-3As shown, the bottom of the guide trough 7 is connected to one end of the slag chute 8. After the vegetable scrap is washed off by the scraper plate 3, it enters the slag chute 8 along the guide trough 7. The other end of the slag chute 8 corresponds to the position below the feed end of the conveyor belt 1. A filter screen 14 is provided on the bottom surface of the discharge position at the other end of the slag chute 8. A water collection trough 9 is provided below the slag chute 8. The maximum width of the water collection trough 9 is greater than the width of the conveyor belt 1, ensuring that all water dripping from the conveyor belt 1 is collected. After the vegetable scrap is conveyed to the discharge position by the water flow, the vegetable scrap is discharged, and the water enters the water collection trough 9 from the filter screen 14. The bottom of the end of the water collection trough 9 corresponding to the discharge position of the slag chute 8 is connected to the buffer tank 12 through the return pipe 13. A flushing pipe 15 is provided on the inner side of the other end of the water collection trough 9. The flushing pipe 15 leads to the buffer tank 12 and uses a water pump to supply water to clean the water collection trough 9. Water in the slag chute 8 is filtered by filter screen 14 before entering the buffer tank 12. The water collection trough 9, which only receives water droplets from the conveyor belt 1 after cleaning, has relatively clean water and can be directly used for cleaning; this water does not require filtration. After being collected and returned to the buffer tank 12, the water can be reused to rinse the water collection trough 9. The water collection trough 9 only needs to be rinsed periodically. The lowest point of the water collection trough 9 should be higher than the buffer tank 12; the water in the water collection trough 9 flows back due to gravity. A drain pipe 19 is provided on one side of the buffer tank 12; the drain pipe 19 leads to the sedimentation tank.

[0025] like Figure 5 As shown, specifically, the rotating mechanism 4 includes: a mounting box 4.1, a bracket 4.2, a worm gear 4.3, a worm 4.4, a turntable 4.5, and a rotating shaft 4.6. The mounting box 4.1 is fixed to one side of the slag guide trough 7. The scraper plate 3 is rotatably connected to the slag guide trough 7 via the rotating shaft 4.6. The worm gear 4.3 is fixed to one end of the rotating shaft 4.6 that extends out of the outside of the slag guide trough 7. The bracket 4.2 is fixed inside the mounting box 4.1. The worm 4.4 is rotatably mounted on the bracket 4.2. The worm gear 4.3 and the worm 4.4 cooperate for transmission. The top of the mounting box 4.1 is equipped with a turntable 4.5. The turntable 4.5 is connected to the worm 4.4 to control the rotation of the worm 4.4. The worm gear 4.3 and the worm 4.4 prevent the rotating plate from rotating on its own. The rotation angle of the rotating plate is adjusted by the turntable 4.5, which facilitates operation by the operator. Unless otherwise described, the fixing methods mentioned above are all achieved by welding or threaded fastening using common techniques employed by industry professionals.

[0026] The working principle is as follows:

[0027] During the beet conveying process, beet pulp adheres to the surface of conveyor belt 1. When conveyor belt 1 rotates to the position of scraper plate 3, scraper plate 3 scrapes the beet pulp from the surface of conveyor belt 1. The beet pulp easily adheres to scraper plate 3, and this position is washed using flushing nozzle 6. The beet pulp is then conveyed along the guide chute 7 into the chute 8. After the water flow carries the beet pulp to the discharge position of chute 8, the water flows through filter screen 14 into the lower water collection tank 9 for external discharge. The water in water collection tank 9 enters the buffer tank 12 through return pipe 13. The water in buffer tank 12 can be pumped back to water collection tank 9 for cleaning. The water in buffer tank 12 can be transferred to sedimentation tank through drain pipe 19. The angle of scraper plate 3 is adaptively adjusted according to the angle of conveyor belt 1, and the angle of scraper plate 3 is adjusted by turntable 4.5.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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.
