[0021] Reference Figures 1 to 4 In an embodiment of the utility model, a device for screening, dust prevention and impurity removal of brominated flame retardant powder materials comprises: a screening box 1, a box cover 2 is provided at the top of the screening box 1, a feed hopper 3 is provided through the top of the box cover 2, a spring 4 is fixedly connected to the bottom end of the screening box 1, a support frame 5 is fixedly connected to the bottom end of the spring 4, a vibration motor 6 is fixedly connected to the bottom end of the screening box 1, a sieve plate 8 is fixedly connected to the inner end of the screening box 1, a strong magnetic plate 9 is fixedly connected to the top of the sieve plate 8, and a discharge pipe 12 is connected to one side of the bottom end of the screening box 1.

[0022] Reference Figure 4 There are multiple groups of strong magnetic plates 9, which are evenly distributed on the top of the sieve plate 8 and the bottom of the screen box 1.

[0023] With the above solution, the screened brominated flame retardant powder material can be magnetically attracted again by the strong magnetic plate 9 at the bottom of the screening box 1 to remove rust impurities therein and improve the removal efficiency of rust impurities.

[0024] Reference Figures 2 to 4 The top of the sieve plate 8 is provided with multiple groups of screening holes. The sieve plate 8 is L-shaped and is fixedly connected to the inside of the screening box 1. A discharge pipe 11 is connected to one side of the bottom end of the screening box 1, and the discharge pipe 11 is arranged on one side of the sieve plate 8.

[0025] By adopting the above solution, large particles of impurities on the sieve plate 8 can be discharged through the discharge pipe 11 to prevent excessive accumulation of large particles of impurities, which would affect the screening of the brominated flame retardant powder material.

[0026] Reference Figures 4 and 5 The side end of the screening box 1 is provided with a sliding groove 13, and the sliding groove 13 is provided with two groups. The side end of the screening box 1 is fixedly connected to the mounting bracket 14, and the mounting bracket 14 is provided with an anti-blocking device 7. The anti-blocking device 7 includes a linear drive 71 fixedly arranged with the mounting bracket 14, and the movable end of the linear drive 71 is fixedly connected to a connecting plate 72, and the side end of the connecting plate 72 is fixedly connected to a scraper 73. There are two groups of scrapers 73, one group of scrapers 73 runs through one group of sliding grooves 13, and abuts against the top of the sieve plate 8, and one end of the other group of scrapers 73 runs through another group of sliding grooves 13, and abuts against the bottom end of the inner part of the screening box 1. The bottom of the scraper 73 is provided with an avoidance groove 74, and there are multiple groups of avoidance grooves 74. The avoidance grooves 74 are adapted to the strong magnetic plate 9. Each group of scrapers 73 is fixedly connected to a baffle 75 on the side end. 75 is arranged in the sliding groove 13 and is plugged into the sliding groove 13. The length of the baffle 75 is greater than the length of the sliding groove 13. The linear drive 71 includes a fixed frame 711, which is fixedly connected to the mounting frame 14. A screw rod 713 is rotatably connected to the fixed frame 711. A slide rail 712 is provided at the side end of the screw rod 713. The slide rail 712 is fixedly connected to the fixed frame 711, and two groups of slide rails 712 are provided, which are symmetrically distributed on both sides of the screw rod 713. A sliding block 714 is threadedly connected to the outer side of the screw rod 713, and the sliding block 714 is slidably connected to the slide rail 712. A driving motor 715 is fixedly connected to the side end of the fixed frame 711. The output end of the driving motor 715 passes through the fixed frame 711 and is fixedly connected to the screw rod 713. The top of the sliding block 714 is fixedly connected to the connecting plate 72.

[0027] Adopting the above scheme: the anti-blocking device 7 can make the material fully contact with the strong magnetic plate 9, improve the removal efficiency of rust impurities, and prevent the screening holes on the screen plate 8 from being blocked. The baffle 75 can block the sliding groove 13 during the movement of the scraper 73, so that the screening box 1 is in a relatively closed state, preventing dust from being blown out during the screening process.

[0028] The working principle of the utility model is as follows: when in use, the material to be screened is first poured into the screening box 1 through the feed hopper 3, so that the material falls on the screen plate 8, and then the driving motor 715 and the vibration motor 6 are started at the same time, and the screening box 1 is continuously vibrated by the vibration motor 6 and the spring 4, thereby screening the material on the screen plate 8, so that the brominated flame retardant powder material passes through the screening holes on the screen plate 8 and falls on the bottom end of the screen box 1, while the large particles of debris in the brominated flame retardant powder material remain on the screen plate 8, and as the screen box 1 The continuous vibration makes the material on the screen plate 8 and the material at the bottom of the sub-screen box 1 move to the discharge pipe 11 and the discharge pipe 12 respectively. During the movement, the material on the screen plate 8 and the material at the bottom of the sub-screen box 1 pass through multiple groups of strong magnetic plates 9, which make the strong magnetic plates 9 adsorb the iron filings mixed in the material and remove them. While the material is moving, the driving motor 715 drives the screw rod 713 to rotate, driving the sliding block 714 to slide on the slide rail 712, so that the two groups of scrapers 73 are respectively moved on the screen plate 8 and the sub-screen box 1. The reciprocating movement on the bottom end makes the material fully contact with the strong magnetic plate 9 and prevents the screening holes on the screen plate 8 from being blocked. The brominated flame retardant powder material screened out is then moved to the discharge pipe 12 for discharge, and the large particle impurities on the screen plate 8 are moved to the discharge pipe 11 for discharge; by being equipped with multiple sets of strong magnetic plates 9, the brominated flame retardant powder material in the screening process can be effectively magnetically attracted. The strong magnetic plate 9 can effectively adsorb and remove rust impurities in the material, ensuring the purity and quality of the final product, so that the rust impurities are removed synchronously during the screening process, thereby improving the preparation efficiency. The scraper 73 can continuously clean the surface of the screen plate 8 during the screening process, keeping the screening holes unobstructed, thereby improving the screening efficiency. During the movement of the scraper 73, the sliding groove 13 can be blocked by the cooperation of the baffle 75 to prevent dust from being blown out and keep the working environment clean. The large particle impurities on the screen plate 8 can be discharged through the discharge pipe 11 to prevent the large particle impurities from accumulating too much during the screening process, thereby affecting the screening effect of the powder material.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
