[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.

[0023] like Figure 1-3 As shown, the utility model proposes a conveyor belt cleaning device for baking soda production, including a conveyor belt body 1 and a cleaning roller 5. A box body 2 is provided below the conveyor belt body 1. The conveyor belt 11 at the bottom of the conveyor belt body 1 moves from right to left and enters the box body 2 through openings on the left and right sides above the box body 2. The box body 2 below the conveyor belt 11 is divided from right to left into a first cleaning chamber 201, a second cleaning chamber 202 and a third cleaning chamber 203 by two vertical partitions 3. A scraper 4 is provided above the first partition 3 on the right side along the moving direction of the conveyor belt 11. A certain gap is provided between the scraper 4 and the belt surface of the conveyor belt 11, so that large pieces of material adhering to the conveyor belt 11 can be effectively scraped off and fall into the first cleaning chamber 201.

[0024] A roller supported under the conveyor belt 11 is installed on the top of the left partition 3 to support the conveyor belt 11 and avoid friction between the partition 3.

[0025] The cleaning roller 5 is arranged in the middle second cleaning chamber 202 and abuts against the conveyor belt 11 through a spring assembly, which includes a support plate 51 and a tension spring 52. The cleaning roller 5 is installed at one end of the support plate 51, and the other end of the support plate 51 is hinged downward on the partition 3 of the middle cleaning chamber, and a tension spring 52 is connected between the support plate 51 and the partition 3; the cleaning roller 5 is driven to rotate by a motor, and the motor (not shown in the figure) is installed on the support plate 51. Under the elastic force of the tension spring 52, the support plate 51 can be driven to swing upward, so that the cleaning roller 5 effectively abuts against the conveyor belt 11, and the rotation direction of the cleaning roller 5 is opposite to the movement direction of the conveyor belt 11, which has a better cleaning effect on the materials on the conveyor belt 11.

[0026] A high-pressure gas nozzle 6 is provided in the third cleaning chamber 203 on the leftmost side toward the conveyor belt 11. The high-pressure gas nozzle 6 is connected to an external gas source. The high-pressure gas nozzle 6 can be used to blow high-pressure gas toward the conveyor belt 11 to further remove fine materials adhering to the conveyor belt 11, and the cleaning effect is better.

[0027] A lower hopper 22 is provided below the partition 3, and a material storage chamber 204 is provided below the lower hopper 22. The materials falling from the upper cleaning chamber are collected by the lower hopper 22 and discharged downward into the material storage chamber 204, so that the materials can be effectively collected. In addition, an anti-blocking vibrator 221 is installed at the bottom of the lower hopper 22 to prevent the materials from gathering on the inner wall of the lower hopper 22, thereby playing an effective anti-blocking role.

[0028] A material receiving plate 7 is horizontally movable at the bottom of the material storage chamber 204, and the material receiving plate 7 slides against the front and rear side walls of the material storage chamber 204. A discharge port 21 is provided on the right side of the material storage chamber 204, and a driving component is provided in the material storage chamber 204 away from the discharge port 21 to drive the material receiving plate 7 to move outward to unload.

[0029] The driving assembly includes a hydraulic cylinder 8 installed in the material storage chamber 204, and the material receiving support plate 7 is of L-shaped design. Guide grooves are symmetrically provided on the front and rear side walls of the material storage chamber 204. The guide grooves include a horizontal groove 23 and an arc groove 24. The arc groove 24 is arranged upward near the discharge port 21 and is connected to the middle of the horizontal groove 23; the tail of the hydraulic cylinder 8 is hinged on the box body 2, and its piston rod is hinged to the vertical part of the material receiving support plate 7; the front and rear side surfaces of the horizontal part of the material receiving support plate 7 are successively installed with a first guide roller 71 and a second guide roller 72. Driven by the hydraulic cylinder 8, the two guide rollers first slide to the right in the horizontal groove 23, and after the second guide roller 72 moves to the right end of the horizontal groove 23 close to the discharge port 21, as the hydraulic cylinder 8 continues to extend, the first guide roller 71 will move upward along the arc groove 24, and the material receiving pallet 7 will flip clockwise with the second guide roller 72 as the center, thereby dumping the material on the material receiving pallet 7 from the discharge port 21, without the need for manual unloading, and is more convenient to use.

[0030] When the utility model is used, after the conveyor belt 11 enters the box body 2, the scraper 4, the cleaning roller 5 and the high-pressure air nozzle 6 are used to perform cleaning operations in sequence, so that the baking soda material adhering to the conveyor belt 11 can be thoroughly and effectively removed. The cleaned materials fall onto the receiving pallet 7 through the unloading hopper 22. When the materials on the receiving pallet 7 are unloaded, under the guidance of the guide chute, the hydraulic cylinder 8 is used to push the receiving pallet 7 to move horizontally toward the discharge port 21 side, and then flip outward with the second guide roller 72 as the center, so that the receiving pallet 7 can be flipped outward from the discharge port 21, thereby dumping the materials on the receiving pallet 7, without the need for manual unloading, and more convenient to use.
