[0032] Box 1 has a connected box 5 welded to its top. The top of box 5 has a feed inlet 6 for placing clumps of salt. The feed inlet 6 extends through the top of box 5 into the interior. To facilitate the crushing of the salt, the end of the feed inlet 6 is located on one side of the fixed frame 9, close to the electric push rod 3. Under the action of the screen plate 8 and the crushing roller 12, the crushed salt is directly screened. The bottom of box 1 has a discharge port. To facilitate the periodic cleaning of the inside of box 1, a hinged door is provided on the side of box 1 away from the drive motor 2. The door is connected by a latch. The inner bottom wall of box 1 has a funnel-shaped material gathering trough, which is connected to the discharge port, so that the screened salt particles can be quickly collected and discharged.

[0033] The inner wall of the box 5 is provided with two symmetrical slide rails, and the slide rails are slidably connected to the slide plate 11. In order to ensure the smooth sliding of the slide plate 11, there is a space allowance between the slide plate 11 and the slide rail to facilitate the movement of the slide plate 11. The side wall of the slide plate 11 is welded to the mesh plate 8. The inner wall of the mesh plate 8 is also provided with a filter screen 7. One end of the mesh plate 8 is connected to the moving part of the electric push rod 3. The fixed part of the electric push rod 3 is inclined and fixed to the side wall of the box 5. Under the action of the inclined slide rails and the electric push rod 3, the mesh plate 8 can perform initial screening of the crushed salt particles. With the assistance of the high-frequency telescopic electric push rod 3, it completes high-speed reciprocating motion.

[0034] The top of the box body 5 is also provided with a telescopic rod 4 for easy adjustment. The movable part of the telescopic rod 4 passes through the top of the box body 5 and is connected to the fixed frame 9. The bottom of the fixed frame 9 is provided with a rotatably connected crushing roller 12. The crushing roller 12 abuts against the top of the screen plate 8. Under the action of the high-frequency telescopic electric push rod 3, the screen plate 8, together with the telescopic rod 4 and the crushing roller 12, completes the crushing of the clumps of salt that enter the box body 5 through the feed port 6.

[0035] The other end of the screen plate 8 is also provided with a first discharge port 13. The first discharge port 13 is slidably connected to the first discharge plate provided at the end of the box body 5. The first discharge port 13 and the first discharge plate facilitate the removal of screened impurities. Symmetrical moving columns 17 are also connected on both sides of the first discharge port 13. The side wall of the moving column 17 is slidably connected to the box body 5. The moving column 17 is slidably connected to a fixed column 10. The fixed column 10 is connected to the side wall of the box body 5 by screws. A spring 21 with a damper is provided inside the fixed column 10. The side wall of the spring 21 is slidably connected to the inner wall of the fixed column 10. A circular plate 22 connected to the spring 21 is also provided inside the fixed column 10. The top of the circular plate 22 is fixed to the end of the moving column 17, so that the screen plate 8 completes the reciprocating motion of the screen plate 8 under the action of the electric push rod 3 and the moving column 17.

[0036] Two symmetrical but staggered drive motors 2 are provided on one side of the housing 1. The output shaft of the drive motor 2 passes through the side wall of the housing 1 and is connected to one end of the rotating shaft 19 through a coupling. The other end of the rotating shaft 19 is rotatably connected to the inner wall of the housing 1. Several cams 20 are evenly distributed on the outer side of the rotating shaft 19. The cams 20 abut against the vertical plate 16. The inner wall of the vertical plate 16 is provided with a groove that fits the cam 20. The end of the vertical plate 16 is connected to the screen plate 14. By rotating the output shaft of the drive motor 2, the screen plate 14 is driven to move, thereby vibrating the screen plate 14 and accelerating the screening.

[0037] A screen 15 is installed inside the screen plate 14. The screen 15 will further screen the salt particles after the initial screening in the box 5 to improve the production quality of the product. With the help of the moving column 17, the circular plate 22, the spring 21 and the fixed column 10 set on the top of the screen plate 14, the screen plate 14 can vibrate at high frequency under the action of the cam 20. With the inclined screen plate 14, the screening efficiency of the device is further improved. A second discharge port 18 is provided at the end of the box 1 away from the box 5.

The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0039] Working principle

[0040] This drying device for chemical product production involves placing dried salt blocks into the box 5 through the feed inlet 6, controlling the electric push rod 3 to move the connected screen plate 8, and cooperating with the telescopic rod 4, the fixed frame 9 and crushing roller 12 connected to the telescopic rod 4. Under the action of the screen plate 8 and the sliding plate 11, the salt blocks are crushed. The screen plate 8 is made to vibrate at high frequency inside the box 5 through the moving column 17, the fixed column 10, the spring 21 and the circular plate 22, which accelerates the crushing and initial screening.

[0041] Then, the crushed salt particles enter the interior of the sieve plate 14 through the channel connecting the box 5 and the housing 1. Under the action of the sieve 15, the particles pass through the connected vertical plate 16, which is connected to the cam 20. This controls the output shaft of the drive motor 2 to rotate, causing the sieve plate 14 to vibrate up and down. In conjunction with the fixed column 10 and the moving column 17, the crushed salt particles are screened. Finally, the screened salt particles are discharged through the discharge port.
