Description

Technical Field

[0001] This utility model belongs to the field of silicon material production and relates to silicon material conveying technology, specifically a dustproof device for silicon material conveying. Background Technology

[0002] Silicon material transportation is a crucial step in the production and processing of silicon materials, directly affecting production efficiency and product quality.

[0003] Common silicon material conveying methods typically involve transporting silicon material that meets dimensional requirements via a conveyor belt or conveyor rollers. The silicon material is usually placed into a discharge device, which includes a receiving tray that slides on the surface of the conveyor belt and a device that rotates the receiving tray. When the receiving tray is below the discharge device, it receives a certain amount of silicon material, which is then moved to a new position by the conveyor belt or conveyor rollers. During the movement, the accumulated silicon material is manually flattened. After moving to the rotating device, the receiving tray rotates 180 degrees, and the silicon material is poured to the designated position.

[0004] However, during the silicon material transportation process, from the time the silicon material is unloaded until it reaches the designated location, it is in direct contact with the external environment. Since silicon material is often in the form of fine powder with poor particle flowability, dust is easily generated during transportation. Furthermore, static electricity is easily generated due to friction during transportation, which further exacerbates the generation and airborne nature of dust. Airborne dust may be inhaled by workers, affecting their health. If dust adheres to the surface of equipment, it will affect the operation and service life of the equipment. At the same time, if dust from the environment mixes into the silicon material, it will reduce the purity of the silicon material and affect the weight of the final product.

[0005] Therefore, this utility model proposes a dustproof device for conveying silicon material. Utility Model Content

[0033] It should be noted that the conveyor frame 1 shown in the figure is a partial cut-out view, and the conveyor frame 2 can move and circulate inside the conveyor frame 1;

[0034] A dustproof mechanism is provided between the conveyor frame 2 and the conveyor rack 1, and the dustproof mechanism includes:

[0035] Dustproof frame 41, which is detachably connected to conveyor frame 2. Dustproof block 42 and action block 43 are rotatably connected inside dustproof frame 41. Dustproof block 42 is located on the side close to flipping block 3. Both dustproof block 42 and action block 43 are concave.

A transfer block 45 is slidably connected to the surface of the mating block 44, and the transfer block 45 is slidably connected to the actuating block 43. Several driving gears 46 are rotatably connected inside the actuating block 43. The driving gears 46 are divided into two groups. The size of the driving gears 46 closer to the conveying frame 2 in the same group is smaller than that of the driving gears 46 farther from the conveying frame 2. A synchronization component is provided between the two groups of driving gears 46. A driving rack 47 is fixedly connected to the surface of the transfer block 45. The driving gears 46 on the lower side mesh with the driving rack 47. A transfer gear 48 is rotatably connected to the surface of the driving rack 47.

[0037] Two drive racks 410 are fixed on the side of the conveyor frame 1 away from the flipping block 3. The drive racks 410 are located on opposite sides inside the conveyor frame 1 and are in different positions. Both drive racks 410 mesh with the drive gear 46 on the upper side.

[0038] In practical application, the dustproof device for conveying silicon material has a detachable dustproof frame 41 on the surface of the conveying frame 2 for conveying silicon material. The dustproof frame 41 is equipped with a rotatable dustproof block 42 and an action block 43 to ensure that the dustproof mechanism does not hinder the feeding and dumping of silicon material. The action block 43 is equipped with a sliding transfer block 45 and a fitting block 44 to seal the silicon material entry and exit points. This ensures that silicon material dust will not spread into the environment during transportation and that dust in the external environment will not come into contact with the silicon material, thereby ensuring the quality of the silicon material and preventing silicon material dust from affecting the operation of the equipment or the health of the operators.

[0039] In some specific implementations, a driving rod 51 and an actuating rod 52 are rotatably connected inside the dustproof frame 41.

[0040] In a further embodiment, the scraper bar 54 is arc-shaped on the side near the conveying frame 2, and the cross-sectional dimensions of the scraper bar 54 decrease towards the conveying frame 2.

[0044] The working principle of this utility model is as follows: The conveying frame 2 slides towards the surface of the flipping block 3 under the action of the conveying roller. When the conveying frame 2 slides to the position of the unloading hopper, the driving rack 410 on one side contacts the driving gear 46 on the upper side. The driving gear 46 rotates and drives the scraper rod 54 to slide, causing the driving rack 47 to slide away from the flipping block 3. The transfer block 45 slides and drives the transfer gear 48 to rotate. Then, under the action of the transfer rack 49, the mating block 44 slides into the action block 43. The silicon material enters the conveying frame 2 and continues to slide. The driving gear 46 contacts the driving rack 410 on the other side. The driving gear 46 rotates in the opposite direction. The mating block 44 contacts the dustproof block 42. At the same time, the scraper rod 54 scrapes the silicon material. After sliding to the surface of the flipping block 3, the cylinder fixes the position of the conveying frame 2. The flipping block 3 rotates. The dustproof block 42 and the mating block 44 rotate under the action of gravity. The silicon material tilts. After the weightlessness, the two are reset under the action of the rotating spring 73.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
