[0001] This utility model relates to the field of silicon carbide micro powder screening technology, and in particular to a silicon carbide micro powder mixing and screening device. Background Technology

[0002] During use, silicon carbide micro powder mixing and screening devices often have a large number of micro powder particles on the surface of the vibrating filter plate. This increases the risk of larger particles clogging the filter holes. General silicon carbide micro powder mixing and screening devices lack measures to handle these clogging particles, reducing their practicality. A patent application published on the Chinese Patent Network, titled "A Screening Device for a Silicon Carbide Micro Powder Mixer" (application number "202020745511.7"), uses a rotating screening cylinder and scraper to remove particles clogging the filter holes. However, this device cannot promptly remove large particles during use, causing them to be constantly squeezed by the scraper, increasing the risk of them being forced into the filter holes and becoming completely stuck, thus reducing the device's efficiency.

[0011] Beneficial effects:

[0012] Compared with existing technologies, this silicon carbide micro powder mixing and screening device uses a servo motor, mounting plate, right-angle strip, and observation window to simultaneously fix two vibrating filter plates.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-5 This utility model discloses a silicon carbide micro powder mixing and screening device, which includes: a box body 1, a mixing box 2 fixedly connected to the upper surface of the box body 1, a feeding opening 4 and a stirring mechanism 3 fixedly connected to the upper surface of the mixing box 2, the output end of the stirring mechanism 3 being located on the inner wall of the mixing box 2, the stirring mechanism 3 being composed of a motor, a long rod and blades, wherein the blades of the stirring mechanism 3 are of a comb-like structure, and a baffle 5 is slidably connected inside the mixing box 2. When using the device, the output end of the stirring mechanism 3 is in close contact with the upper surface of the baffle 5. The above components cooperate to form the mixing structure of the device for mixing silicon carbide micro powder, wherein the baffle 5 serves as the bottom wall of the mixing box 2, thereby transferring the mixed silicon carbide micro powder to the screening area of ​​the device by pushing and pulling the baffle 5.

[0023] The front and rear walls and the right end of the top wall of the housing 1 are respectively rotatably connected to observation windows 9 and sealing plates 10. The width of the observation window 9 is greater than the thickness of the vibrating filter plate 7. The two vibrating filter plates 7 rotate and change position through the installation point of the observation window 9. The length and width of the sealing plate 10 are both greater than the length and width of the vibrating filter plate 7. The vibrating filter plate 7 enters and exits the housing 1 through the installation point of the sealing plate 10. The observation window 9 and the sealing plate 10 cooperate with each other to close the housing 1. The rotating opening and closing structure of the observation window 9 and the sealing plate 10 improves the convenience of taking out the internal parts of the housing 1.

[0024] A rotating bracket 6 is fixedly connected inside the housing 1. Vibrating filter plates 7 are provided at both ends of the rotating bracket 6. The two vibrating filter plates 7 are distributed vertically opposite to the mixing box 2 and the sealing plate 10. The rotating bracket 6 consists of a servo motor 13, a mounting plate 14, and two sets of right-angle strips 15. The mounting plate 14 and the right-angle strips 15 are snapped into the vibrating filter plates 7. The servo motor 13 is fixedly connected to the housing 1. The mounting plate 14 is fixedly connected to the output end of the servo motor 13. The two sets of right-angle strips 15 are fixedly connected to the left and right surfaces of the mounting plate 14. The rotating bracket 6 provides conditions for the two vibrating filter plates 7 to rotate and change position. The vibrating filter plates 7 are filter plates with vibration mechanisms on their surfaces. The mounting plate 14 is snapped into one end of the vibrating filter plate 7 with the vibration mechanism.

[0025] The interior of the housing 1 is equipped with a storage box 8 and a partition 11. The storage box 8 is used to recycle qualified silicon carbide micro powder. The upper end of the partition 11 passes through the upper surface of the housing 1 and is slidably connected to the housing 1. The lower end of the partition 11 is fixedly connected with multiple dust-proof cloth strips 12. The lower end of the dust-proof cloth strips 12 is in contact with the surface of the servo motor 13. The partition 11 and the dust-proof cloth strips 12 cooperate with each other to limit the dispersion range of silicon carbide micro powder, reduce the amount of dust in the space to the right of the partition 11, and reduce the impact of dust on the recycling of large particles.

[0026] Working principle: After mixing silicon carbide powder for a period of time, pull out the baffle 5, so that the silicon carbide micro powder above the baffle 5 falls onto the surface of the vibrating filter plate 7 for filtration. The operator can directly observe the filtration situation through the observation window 9. When the filtration efficiency is found to be significantly reduced, stop opening the baffle 5 to continuously add silicon carbide micro powder to the filter plate and wait for the vibrating filter plate 7 to complete the filtration. After the filtration is completed, open the observation window 9, lift the partition 11, and then turn on the servo motor 13 to drive the two vibrating filter plates 7 to rotate, so that the two vibrating filter plates 7 are swapped. After the swap, reset the partition 11 and the observation window 9. At this time, the screening of silicon carbide micro powder can continue. At the same time, open the sealing plate 10 to lift and remove the vibrating filter plate 7 that is blocked on the right side through the installation point of the sealing plate 10. Pour the large particles on the surface of the removed filter plate to the designated position, and then press down the removed filter plate to make it engage with the right side of the rotating bracket 6. Finally, reset the sealing plate 10 to close the box 1.
