[0022] See also Figures 1 to 3The utility model provides a technical solution: a magnesium hydroxide processing raw stone screening equipment, comprising: a frame 1, a screening box 6 is movably installed in the middle of the frame 1, a feed inclined plate 3 is fixedly installed on the upper front side of the screening box 6, a screen plate 8 is rotatably installed in the lower part of the screening box 6, a discharge inclined plate 5 is fixedly installed on the lower rear side of the screening box 6, a vibration component 2, the vibration component 2 includes two groups of guide rods 27, each group of guide rods 27 is symmetrically distributed and fixedly installed on both sides of the top of the frame 1, and the outer periphery of the same group of guide rods 27 are all slidably installed with movable plates 28, and the middle of the top of the movable plate 28 is fixedly installed with a connecting plate 21, and the connecting plate 2 1 are fixedly mounted on both sides of the screening box 6 on one side close to each other, and bearing seats 213 are symmetrically fixedly mounted on both sides of the top of the frame 1. A drive shaft 211 is rotatably mounted on the side of the bearing seats 213 on the same side close to each other, and a cam 210 is fixedly mounted on the middle of the outer periphery of the drive shaft 211. A roller 29 is fixedly mounted on the middle of the bottom end of the movable plate 28. A spring 26 is symmetrically fixedly mounted on the bottom end of the movable plate 28. The bottom ends of the springs 26 are respectively fixedly mounted on the upper part of the frame 1 on the same side. By setting the spring 26, when the movable plate 28 moves axially along the guide rod 27, the elastic energy accumulated when the spring 26 is compressed or stretched can be In order to assist the vibration of the movable plate 28, a driving mechanism is provided in each group of vibration components 2. A hydraulic cylinder 7 is symmetrically fixedly installed on the rear of the inner wall of the screening box 6. The driving ends of the hydraulic cylinder 7 are respectively fixedly installed on the upper rear side of the screen plate 8. The magnesium hydroxide raw stone is added into the screening box 6 through the feed inclined plate 3. At this time, the driving mechanism can control the rotation of the driving shaft 211, thereby realizing the synchronous rotation of the cam 210 following the driving shaft 211. Since the cam 210 will abut against the roller 29 at the bottom of the movable plate 28 when it rotates, the movable plate 28 can be moved up and down along the axial direction of the guide rod 27, thereby realizing the upward and downward movement of the screening box 6 in the frame 1. The sieve box 6 is moved downward by controlling the rotation frequency of the stepper motor 25 in the driving mechanism, and then the vibration frequency of the screening box 6 can be controlled, so that the magnesium hydroxide raw stone in the screening box 6 can be vibrated, and a sieve plate 8 is provided in the screening box 6. The magnesium hydroxide raw stone that meets the filtering adjustment can fall from the bottom of the screening box 6, and the magnesium hydroxide raw stone that does not meet the filtering conditions will remain on the surface of the sieve plate 8. At this time, the sieve plate 8 can be rotated downward by controlling the hydraulic cylinder 7 until the sieve plate 8 is connected to the discharging inclined plate 5. Under the action of gravity, the magnesium hydroxide raw stone will fall along the discharging inclined plate 5, which is convenient for the next screening of the magnesium hydroxide raw stone.

[0023] The driving machine includes a driving wheel 24, which drives the driven wheel 212 to rotate through a synchronous belt 22. The driven wheels 212 are fixedly installed on the front end of the driving shaft 211. Fixed plates 23 are fixedly installed on both sides of the top of the frame 1, and stepper motors 25 are fixedly installed on the rear sides of the fixed plates 23. The driving ends of the stepper motors 25 are respectively connected to the driving wheels 24 on the same side. By controlling the stepper motor 25 in the driving mechanism, the stepper motor 25 can drive the driving wheel 24 to rotate. Since the driving wheel 24 and the driven wheel 212 are connected by the synchronous belt 22, the driving shaft 211 and the cam 210 can be rotated synchronously, which facilitates the axial movement of the movable plate 28 along the guide rod 27.

[0024] The dust removal component 4 is arranged inside the screening box 6. The dust removal component 4 includes a connecting hose 43. The upper portion of the connecting hose 43 passes through both sides of the top of the screening box 6 and a collection cover 45 is fixedly installed at the upper end of the connecting hose 43. An exhaust fan 44 is installed on the outer periphery of the connecting hose 43. A processing box 41 is fixedly installed on both sides of the lower part of the frame 1. The top of the processing box 41 is respectively connected to the lower portion of the connecting hose 43 on the same side. An exhaust pipe 42 is fixedly installed on the top of the processing box 41. When the magnesium hydroxide raw stone is screened in the screening box 6, a large amount of dust will be generated. At this time, the exhaust fan 44 cooperates with the collection cover 45 to allow the dust generated in the screening box 6 to enter the processing box 41 along the connecting hose 43. Since there is a certain amount of water in the processing box 41, the dust-containing airflow will be discharged into the water at this time. The water in the processing box 41 can absorb the dust in the water, and the treated airflow will be discharged through the exhaust pipe 42, so as to avoid the magnesium hydroxide raw stone from generating a large amount of dust during the screening process, which affects the health of the staff.

[0025] During actual use, the staff adds the magnesium hydroxide raw stone into the screening box 6 through the feed inclined plate 3. At this time, the stepper motor 25 in the driving mechanism cooperates with the active wheel 24, the synchronous belt 22 and the driven wheel 212 to drive the driving shaft 211 to rotate, and then the cam 210 on the outer periphery of the driving shaft 211 can continuously abut against the roller 29 at the lower part of the movable plate 28. With the spring 26, the movable plate 28 can be moved up and down along the axial direction of the guide rod 27, and then the screening box 6 can vibrate. Since the screening box 6 is provided with a screen plate 8, the magnesium hydroxide raw stone can be screened, and during the screening process, the staff turns on the screen plate 8. The exhaust fan 44 can suck the dust in the screening box 6 at this time, and the gas containing dust can enter the processing box 41 through the connecting hose 43. Under the filtration of the water in the processing box 41, the dust can remain in the processing box 41, and the gas without dust can be discharged along the exhaust pipe 42. Then, unqualified magnesium hydroxide rough stone will remain on the surface of the sieve plate 8. At this time, the sieve plate 8 can be tilted by controlling the hydraulic cylinder 7 until the sieve plate 8 is opposite to the discharging inclined plate 5. At this time, the unqualified magnesium hydroxide rough stone will be discharged from the screening box 6 along with the discharging inclined plate 5, and the qualified magnesium hydroxide rough stone will be discharged through the lower part of the screening box 6.
