Description

Technical Field

[0001] The invention relates to the technical field of flame retardant production and processing, in particular to a vibration grading and screening device for producing aluminum hydroxide flame retardant. Background Art

[0002] In industrial production, there are strict requirements for the particle size distribution of aluminum hydroxide flame retardants. Aluminum hydroxide flame retardants with different particle sizes have differences in flame retardancy, dispersibility when added to different materials, and compatibility. Therefore, precise grading and screening technology is required to meet production needs. During the vibration screening of aluminum hydroxide, the eccentric wheel is generally driven to rotate on the motor output shaft to drive the screen to vibrate and screen the aluminum hydroxide powder. When screening a large amount of powder, some powder will be dispersed and accumulated in the corners of the filter due to vibration. It is easy for some powder to accumulate in the corners of the filter, thereby affecting the screening of the powder and further affecting the effect of the aluminum hydroxide powder screening.

[0016] 3. In the present invention, during the sliding process of the sliding block 2, the piston rod will be driven to slide. When the rotating plate approaches the L-shaped plate, the piston rod will push the air inside the air cylinder at one end to be discharged through the L-shaped groove to a position in the sliding groove away from the movable plate, thereby blowing away the powder when the movable plate slides to discharge the powder, thereby avoiding the situation where the powder is piled up together during the pushing process of the spring 1. When the rotating plate is away from the L-shaped plate, the air cylinder will push the gas inside the other end to be discharged to the starting position of the movable plate, thereby preventing the situation where, after the movable plate pushes the powder to be discharged, its original position is not pushed away and sinks to the starting position of the movable plate to cause accumulation, thereby affecting the resetting of the movable plate, thereby improving the efficiency of aluminum hydroxide powder filtration.

When the eccentric wheel rotates, its raised part will contact the sliding rod 111, thereby pushing the sliding rod 111 to slide inside the main body 1 and then drive the filter barrel 112 to shake. After that, the filter barrel 112 will synchronously drive the filter screen 113 to shake, thereby achieving the purpose of filtering the aluminum hydroxide powder.

[0027] The auxiliary assembly 12 includes two fixing frames 121 fixedly connected to the outer surface of the main body 1. The top inner walls of the two fixing frames 121 are fixedly connected to an annular plate 122. The bottom of the annular plate 122 is slidably connected to a rectangular block 123.

Among them, a rectangular groove is provided inside the rectangular block 123, a sliding groove is provided inside the rotating plate 124, two L-shaped grooves are provided inside the rotating plate 124, and a diamond groove is provided on the side wall of the sliding groove. The connecting rod 213 will be pulled by the sliding block 1 214 to reset and rotate, and then the rotating ring 212 will drive the rotating plate 124 to reset and rotate. After that, due to the close distance between the rotating plate 124 and the L-shaped plate 221, the connecting rod 2 222 will be driven to push the sliding block 2 223 to slide inside the sliding groove.

[0028] The rotating member includes a second connecting rod 222 rotatably connected to the outer surface of the first connecting rod 211, the top of the second connecting rod 222 is rotatably connected to the connecting rod 213, and the end of the connecting rod 213 away from the first connecting rod 211 is rotatably connected to the first sliding block 214; Among them, the top of the connecting rod 211 is fixedly connected to the inner wall of the rotating plate 124, the bottom of the rotating ring 212 is fixedly connected to the top of the rotating plate 124, and the outer surface of the sliding block 214 is slidably connected to the inner wall of the rectangular groove. Therefore, when the filter barrel 112 shakes, the teeth inside it will apply a thrust to the sliding block 214 to move it toward the inside of the rectangular block 123 and squeeze the spring 215 to make it contract. Then, during the movement of the sliding block 214, a thrust will be applied to the connecting rod 213 to push the rotating ring 212 to rotate around the connecting rod 211. During the rotation of the rotating ring 212, the rotating plate 124 will be synchronously driven to rotate toward the side away from the L-shaped plate 221.

[0029] The side wall of the sliding block 214 is fixedly connected to a spring 215, and the end of the spring 215 away from the sliding block 214 is fixedly connected to a fixing plate 216; Among them, the side wall of spring 1 215 is fixedly connected to the inner wall of the rectangular groove. When passing through the tooth recess, the sliding block 1 214 will be subjected to the reverse thrust of the spring 1 215 and slide toward the tooth recess outside the rectangular block 123. At the same time, the connecting rod 213 will be pulled by the sliding of the sliding block 1 214 to reset and rotate, and then the rotating ring 212 will drive the rotating plate 124 to reset and rotate.

[0030] The fixing member includes an L-shaped plate 221 fixedly connected to the bottom of the rectangular block 123. The side wall of the L-shaped plate 221 is rotatably connected to a second connecting rod 222. The end of the second connecting rod 222 away from the L-shaped plate 221 is rotatably connected to a second sliding block 223. The side wall of the second sliding block 223 is fixedly connected to a piston rod 224. Among them, the outer surface of the piston rod 224 is slidably connected to two air cylinders 225, and a placement groove is provided at the bottom of the sliding block 223. The side wall of the air cylinder 225 is fixedly connected to the inner wall of the rotating plate 124. The rotating ring 212 will drive the rotating plate 124 to reset and rotate. Then, due to the close distance between the rotating plate 124 and the L-shaped plate 221, the connecting rod 222 will be driven to push the sliding block 223 to slide inside the sliding groove.

[0031] The swing assembly 31 includes a swing plate 312 fixedly connected to the end of the arc spring 311 away from the second sliding block 223, and a push plate 313 is provided on the side wall of the swing plate 312. The side wall of the push plate 313 is fixedly connected to the connecting plate 314; When the cam 313 is in the unlocking state, the cam 314 is unlocked and the lock 315 is unlocked, so the cam 314 can be unlocked, and the cam 314 can be unlocked after unlocking.

[0032] When in use, first start the motor 101 located inside the main body 1, and then when the motor 101 moves, its output shaft will drive the eccentric wheel to rotate. When the eccentric wheel rotates, its raised part will contact the sliding rod 111, thereby pushing the sliding rod 111 to slide inside the main body 1 and then driving the filter barrel 112 to shake. Then, the filter barrel 112 will synchronously drive the filter screen 113 to shake, thereby achieving the purpose of filtering the aluminum hydroxide powder. During the shaking of the filter barrel 112, since the annular plate 122 is connected to the fixing frame 121, when the filter barrel 112 shakes, the teeth inside it will apply thrust to the sliding block 214, causing it to move toward the rectangular block 123. The internal movement squeezes the spring 215 to shrink it, and then during the movement of the sliding block 214, a thrust is applied to the connecting rod 213 to push the rotating ring 212 to rotate around the connecting rod 211. During the rotation of the rotating ring 212, the rotating plate 124 is synchronously driven to rotate toward the side away from the L-shaped plate 221, so that the aluminum hydroxide powder located in the corner filter 113 and the filter barrel 112 is thrown out to the center of the filter for filtration through the rotation of the rotating plate 124, thereby reducing the residual accumulation in the corners due to long use time or when a large amount of powder needs to be filtered, thereby ensuring the effect of filtering the aluminum hydroxide powder.

[0033] When passing through the tooth recess, the sliding block 1214 will be pushed back by the spring 1215 and slide toward the outside of the rectangular block 123 toward the tooth recess. At the same time, the connecting rod 213 will be pulled by the sliding of the sliding block 1214 to pull the rotating ring 212 to reset and rotate. Then the rotating ring 212 will drive the rotating plate 124 to reset and rotate. Then, due to the distance between the rotating plate 124 and the L-shaped plate 221 being close, the connecting rod 222 will be driven to push the sliding block 223 to slide inside the sliding groove. During the sliding process of the sliding block 223, the reset spring will be pulled to extend and the swing plate 312 at the bottom will be used to push the push plate 313 to slide in the diamond groove. Then the swing plate 312 will be driven to reset and rotate. 12 will drive the moving plate 315 to slide toward the inner wall of the filter barrel 112 inside the sliding groove through the connecting plate 314, and collect some of the remaining powder into the sliding groove when the rotating plate 124 is opened outward. When the pushing plate 313 moves along the diamond groove to its bottom, it will not contact the side wall of the swing plate 312, so that under the pull of the return spring, the pushing plate 313 drives the moving plate 315 to slide quickly inside the sliding groove, thereby discharging the powder inside the sliding groove to the outside of the rotating plate 124, reducing the problem that some powder is still in the gap between the filter barrel 112 and the filter screen 113 due to distance problems when the rotating plate 124 rotates, further improving the quality of filtering aluminum hydroxide powder.

[0034] During the sliding of sliding block 223, the piston rod 224 will be driven to slide synchronously. When the rotating plate 124 approaches the L-shaped plate 221, the piston rod 224 will push the air inside the air cylinder 225 at one end through the L-shaped groove to be discharged to a position in the sliding groove away from the movable plate 315, thereby blowing away the powder when the movable plate 315 slides to discharge the powder, thereby avoiding the situation where the powder is piled up during the pushing process of spring 1 215. When the rotating plate 124 is away from the L-shaped plate 221, the air cylinder 225 will push the gas inside the other end 226 to be discharged to the starting position of the movable plate 315, thereby preventing the situation where, after the movable plate 315 pushes the powder to be discharged, its original position is sunken into the starting position of the movable plate 315 because a part of the powder is not pushed away, resulting in accumulation, thereby affecting the reset of the movable plate 315, thereby improving the efficiency of aluminum hydroxide powder filtration.
