[0024] Figures 1-4 In one embodiment of this utility model, a rotary vibrating sieve for aluminum hydroxide includes a main unit 1 and an installation tank 7 located on the right side of the main unit 1. An installation cover 2 is installed on top of the installation tank 7, and the installation cover 2 is threadedly connected to the installation tank 7. A connection port 8 is provided on the installation tank 7. A dust suction port 4 is provided on top of the main unit 1. A connecting pipe 3 is provided between the dust suction port 4 and the installation tank 7, and both ends of the connecting pipe 3 are fixedly connected to the dust suction port 4 and the connection port 8, respectively. A screen 502 is provided inside the main unit 1, and a cleaning mechanism 5 for cleaning the screen 502 is provided. The cleaning mechanism 5 includes a mounting frame 501 located inside the main unit 1. The screen 502 is rotatably connected to the mounting frame 501 via a mounting shaft 503. The cleaning mechanism 5 also includes a mounting frame 511 slidably installed inside the main unit 1. Two sets of symmetrical... The second cylinder 512 of the cloth is equipped with a cleaning brush 507 that is slidably mounted on the mounting frame 511. The mounting frame 511 is equipped with two sets of symmetrically distributed lead screws 508. The mounting bucket 7 and the mounting cover 2 are equipped with a dust removal mechanism 6. The dust removal mechanism 6 includes a fixed frame 601 that is fixedly installed in the mounting cover 2, and a fan 602 that is rotatably mounted on the fixed frame 601. The cleaning mechanism 5 automatically cleans the filter screen after a period of use, reducing the clogging of the pores on the surface of the screen 502 by aluminum hydroxide powder, which would cause the screening efficiency of the screening device to gradually decrease. At the same time, the dust removal mechanism 6, in conjunction with the connecting pipe 3 and the dust suction port 4, collects and removes dust from the main unit 1 at the escaping point, preventing dust from being dispersed in the air and causing pollution to the working environment and affecting the respiratory health of the staff.
[0025] In this embodiment, reference Figure 2 , Figure 3As shown, a gear 504 is sleeved on the mounting shaft 503. A rack 505 and a first cylinder 506 are housed within the mounting frame 501. The rack 505 is slidably connected to the mounting frame 501 and connected to the output end of the piston rod of the first cylinder 506. The rack 505 meshes with the gear 504. The first cylinder 506 drives the rack 505 to slide, cooperating with the gear 504 to rotate the mounting shaft 503 and the screen 502, so that the front of the screen 502 faces downwards and corresponds to the cleaning brush 507. The mounting frame 511 is connected to the output ends of the piston rods of two sets of second cylinders 512. The mounting frame 511 is correspondingly positioned with the mounting frame 501, and the cleaning brush 507 is correspondingly positioned with the screen 502. Activating the second cylinder 512 causes the mounting frame 511 to lift the cleaning brush 507, thus raising the surface of the cleaning brush 507 relative to the screen 502. The two sets of lead screws 508 are respectively connected to the mounting frame 511 through the two ends and rotated through the mounting frame 511 via bearings. The two sets of lead screws 508 are respectively connected to the two ends of the cleaning brush 507 and threadedly connected to the cleaning brush 507. Synchronous pulleys 509 are sleeved on both sets of lead screws 508. A synchronous belt 510 is provided in the mounting frame 511, and the synchronous belt 510 is respectively connected to the two sets of synchronous pulleys 509. When the motor in the mounting frame 511 is started, it drives the lead screws 508 to rotate. Under the action of the synchronous belt 510 and the synchronous pulleys 509, the two sets of lead screws 508 rotate synchronously, smoothly driving the cleaning brush 507 to slide in the mounting frame 511. During the sliding process, the cleaning brush 507 brushes and cleans the surface of the screen 502, reducing the residue of dust particles in the pores of the screen 502 and maintaining the screening efficiency of the screen 502.
[0026] In this embodiment, reference Figure 4 As shown, a driven wheel 603 is sleeved on the fan 602, and a driving wheel 604 is rotatably mounted on the fixed frame 601. A belt 605 is provided on the fixed frame 601, and the belt 605 is connected to both the driving wheel 604 and the driven wheel 603. An installation ring 606 is provided inside the installation barrel 7, and the installation ring 606 is threadedly connected to the inner wall of the installation barrel 7. A filter cylinder 607 is threadedly connected below the installation ring 606. A filter screen 608 is embedded in the installation cover 2. During the operation of the screening device, the motor inside the installation cover 2 is started to drive the driving wheel 604 to rotate, which, in conjunction with the belt 605, causes the driven wheel 603 to rotate. 03 drives the fan 602 to rotate at high speed. When the fan 602 rotates, it discharges the air from the mounting cover 2 and the mounting barrel 7, creating a negative pressure inside the mounting cover 2 and the mounting barrel 7. The air enters the connecting port 8 through the dust suction port 4 and the connecting pipe 3. When the air enters, it carries the dust that escapes from the main unit 1 into the mounting barrel 7. After being filtered by the filter cartridge 607, the dust is blocked and retained inside the mounting barrel 7 and on the surface of the filter cartridge 607. The air then passes through the filter cartridge 607 and the mounting ring 606, passes through the fan 602, and leaves the mounting cover 2 and the mounting barrel 7 through the filter screen, thus completing the collection of dust.
[0027] In this embodiment, during operation, the first cylinder 506 drives the rack 505 to slide, which, in conjunction with the gear 504, causes the mounting shaft 503 and the screen 502 to rotate, so that the front of the screen 502 faces down and aligns with the cleaning brush 507. The second cylinder 512 is then activated, causing the mounting frame 511 to lift the cleaning brush 507, bringing it into contact with the surface of the screen 502. The motor inside the mounting frame 511 is then activated, driving the lead screw 508 to rotate. Under the action of the synchronous belt 510 and the synchronous pulley 509, both sets of lead screws 508 rotate synchronously, smoothly driving the cleaning brush 507 to slide within the mounting frame 511. During this sliding process, the cleaning brush 507 brushes and cleans the surface of the screen 502, reducing dust particles remaining in the pores of the screen 502 and maintaining the screen's integrity. With a screening efficiency of 502, during the operation of the screening device, the motor inside the installation cover 2 drives the rotation of the drive wheel 604, which, together with the belt 605, causes the driven wheel 603 to drive the fan 602 to rotate at high speed. When the fan 602 rotates, it discharges the air inside the installation cover 2 and the installation barrel 7, creating a negative pressure inside the installation cover 2 and the installation barrel 7. The air enters the connection port 8 through the dust suction port 4 and the connecting pipe 3. When the air enters, it carries the dust that escapes from the main unit 1 into the installation barrel 7 simultaneously. After being filtered by the filter cartridge 607, the dust is blocked and retained inside the installation barrel 7 and on the surface of the filter cartridge 607. The air then passes through the filter cartridge 607, the installation ring 606, and the fan 602 before leaving the installation cover 2 and the installation barrel 7 through the filter screen, thus completing the collection of dust.
