Technical Field
[0001] The invention relates to the technical field of silicon micropowder raw material crushing, and in particular to a gradable raw material crusher for processing silicon micropowder of dry-type transformers. Background Art
[0002] Silicon powder for dry-type transformers is an important material used in dry-type transformers. Silicon powder has high purity, low impurity content, stable performance, and excellent electrical insulation performance. It can make the solidified material have good insulation performance and arc resistance, ensuring the electrical safety of dry-type transformers during operation. Silicon powder is mainly used as a filler in dry-type transformers. It is filled in insulating materials such as epoxy resin to increase the strength, hardness and heat resistance of insulating materials, while reducing the cost of materials. It needs to have a reasonable particle size distribution. Generally speaking, silicon powder with moderate particle size and uniform distribution can make dry-type transformers have better performance during use. For example, a specific particle size distribution can make the filler have a good anti-sedimentation effect when in use, ensuring the uniformity of the material.

The crushed silicon micropowder raw material can be screened through the screen 72 component, and the crushed silicon micropowder after screening can be discharged through the scattering component 8; When the silicon micropowder raw material enters the tank body 1 through the feed port 4, the main shaft 62 is driven to rotate on the mesh plate 61 through the output end of the large motor 5, so that the first crushing roller 63 and the three second crushing rollers 64 are contacted and rotated at the same time, so as to squeeze and crush the silicon micropowder raw material entering the tank body 1. The crushed silicon micropowder raw material continues to be crushed through the mesh plate 61. At the same time, when the main shaft 62 rotates, it drives the rotating roller 65 to rotate, and the rotating roller 65 is contacted and rotated with the top of the screen 72, so that the rotating roller 65 performs secondary refinement and crushing on the silicon micropowder raw material that passes through the mesh plate 61 and falls on the screen 72, and then the silicon micropowder raw material can be further crushed. At the same time, when the rotating roller 65 and the silicon micropowder raw material are subjected to secondary refinement and crushing, the rotating mechanism 66 can follow the main shaft 62 to rotate in the tank body 1, so that the rotating mechanism 66 is contacted and rotated with the top of the screen 72; When the main shaft 62 drives the rotating roller 65 to rotate on the screen 72, the main shaft 62 rotates, so that the rotating rod 661 drives the square rod 662 to rotate, so that the square rod 662 drives the inclined block 664 to contact and rotate with the top of the mesh plate 61, so as to avoid the silicon micropowder produced when the rotating roller 65 and the screen 72 are squeezed and rotated, and the silicon micropowder produced when the rotating roller 65 and the screen 72 are squeezed and rotated will be adhered to the screen 72, and then when the screen 72 moves up and down, the inclined block 664 slides in the sliding groove 665 through the sliding rod 666, so that when the rotating rod 661 rotates with the main shaft 62, the inclined block 664 can continue to contact and move with the top of the screen 72, and then when the silicon micropowder raw material is crushed, it is avoided that the silicon micropowder produced during the crushing is adhered to the screen 72 and is difficult to fall naturally; When the silicon micropowder raw material is crushed, the small motor 71 is turned on at the same time, and the output end of the small motor 71 drives the screen 72 to move up and down in the tank body 1 through the connecting block 74, so as to screen the crushed silicon micropowder that falls on the screen 72. At the same time, slide plates 73 are provided on both sides of the screen 72. When the screen 72 is screening, it is avoided that the silicon micropowder raw material is scattered outside the tank body 1 when the crushed silicon micropowder raw material is screened. At the same time, when the output end of the small motor 71 drives the screen 72 to move downward, the screen 72 drives the connecting frame 75 to move downward through the telescopic rod 77, so that the bottom of the connecting frame 75 is squeezed with the limit block 76, so that when the screen 72 moves downward, the connecting frame 75 drives the contact mechanism 79 to contact the screen 72, so as to avoid the silicon micropowder raw material blocking the screen 72 when the crushed silicon micropowder raw material is screened, thereby interfering with the normal passage of the silicon micropowder; When the screen 72 moves downward and contacts the contact mechanism 79 on the connecting frame 75, the silicon micropowder raw material blocked in the mesh of the screen 72 is ejected by the ejector pin 797. At the same time, in order to avoid excessive squeezing force between the silicon micropowder raw material in the mesh of the screen 72 and the inner wall of the mesh of the screen 72, when the squeezing force between the ejector pin 797 and the silicon micropowder raw material stuck between the meshes is greater than the tensile force of the third spring 794, the ejector pin 797 allows the slider 793 to slide on the round rod 795 through the moving rod 792, thereby avoiding excessive squeezing force between the ejector pin 797 and the silicon micropowder raw material when the ejector pin 797 dredges the mesh of the screen 72, thereby causing damage to the side of the ejector pin 797. At the same time, when the contact rod 791 drives the round block 796 to contact the mesh, the round block 796 can scrape off the silicon micropowder adhering to the inner wall of the mesh of the screen 72. After the screen 72 screens the crushed silicon micropowder raw material, the main shaft 62 continuously rotates, so that the main shaft 62 drives the connecting rod 83 to rotate in the tank body 1, so that the connecting rod 83 drives the dispersion rod 85 to rotate, so that the dispersion rod 85 makes rotational contact with the crushed silicon micropowder, thereby avoiding the phenomenon of agglomeration of the silicon micropowder when discharging. At the same time, when the connecting rod 83 rotates, it drives the cleaning mechanism 86 to rotate; When the connecting rod 83 rotates following the main shaft 62, the connecting rod 83 also drives the rotating frame 84 to rotate, so that the straight plate 865 is separated from the movable groove 861 through the connecting rod 863 through the centrifugal force, so that when the silicon micropowder is discharged, the scraper 866 can contact and rotate with the inner side of the tank body 1, thereby avoiding a large amount of silicon micropowder adhering to the inner wall of the tank body 1 when the silicon micropowder is discharged, which is difficult to fall off naturally.
