[0031] Wherein, a cleaning device is provided on the lower surface of the rotating disk 22, and the cleaning device is used to clean the remaining crushed gypsum powder;

[0032] Among them, a driving device is arranged on the top of the crushing tank 4, and the driving device is used to provide power to the crushing device;

[0033] Among them, a discharging device is arranged on the outer surface of the crushing tank 4 near the bottom of the crushing tank support frame 1 .

[0034] Furthermore, the crushing device includes a driving gear 17, which is sleeved and fixedly installed on the outer surface of the first rotating shaft 11 near one end of the rotating disk 22. The outer surface of the driving gear 17 is evenly meshed and connected with three driven gears 19. The second rotating shaft 18 is fixedly installed at the center position of the three driven gears 19, and the three second rotating shafts 18 rotate and penetrate the lower surface of the rotating disk 22. The second rotating shaft 18 is sleeved and fixedly installed at one end away from the driven gear 19. The gypsum raw material enters the crushing tank 4 from the feed port 5, and the motor 7 is started by the controller 3. The output end of the motor 7 rotates to drive the first pulley 8 to rotate. The first pulley 8 drives the second pulley 10 to rotate through the belt 9, thereby driving the first rotating shaft 11 to rotate. The rotation of the first rotating shaft 11 drives the driving gear thereon 17 and the turntable 22 rotate, the driving gear 17 rotates to drive the three driven gears 19 meshing therewith to rotate, and further drives the three second rotating shafts 18 to rotate, thereby driving the crushing rollers 20 thereon to rotate.

The rotation and revolution of the crushing rollers 20 are combined, so that the gypsum raw materials are squeezed and impacted in multiple directions, thereby achieving efficient crushing, reducing energy consumption, and improving production efficiency. Due to the rotation and revolution of the crushing rollers 20, the force on the gypsum raw materials in the crushing process is more uniform, so that the particle size of the crushed products is more uniform, which helps to improve product quality and stability.

The residual gypsum powder is cleaned in time during the crushing process to ensure that the inside of the crushing equipment is always clean, which avoids the blockage and agglomeration problems caused by the accumulation of residues, thereby ensuring the continuity and efficiency of the crushing process. The residual gypsum powder may be mixed with new raw materials, resulting in unstable composition and quality of the final product. By cleaning the residues during the crushing process, it can be ensured that each batch of gypsum powder is pure, thereby improving the quality and stability of the product. Regularly cleaning the residual gypsum powder can avoid the equipment from needing additional cleaning and cleaning steps due to blockage, which reduces unnecessary energy consumption and costs and extends the service life of the equipment.

[0037] Furthermore, the driving device includes a motor 7, which is fixedly mounted on the top of the crushing tank 4 at one end away from the center, and the output end of the motor 7 is sleeved and fixedly mounted with a first pulley 8;

[0041] Working principle: When using the device, the gypsum raw material enters the crushing tank 4 from the feed port 5, and the motor 7 is started by the controller 3. The output end of the motor 7 rotates to drive the first pulley 8 to rotate. The first pulley 8 drives the second pulley 10 to rotate through the belt 9, thereby driving the first rotating shaft 11 to rotate. The rotation of the first rotating shaft 11 drives the driving gear 17 and the turntable 22 thereon to rotate. The driving gear 17 rotates to drive the three driven gears 19 meshing therewith to rotate, and further drives the three second rotating shafts 18 to rotate, thereby driving the crushing rollers 20 thereon to rotate. The gear 17 cooperates with the three driven gears 19, and the three crushing rollers 20 rotate and squeeze each other to crush the gypsum raw materials. At the same time, they revolve around the driving gear 19 and squeeze the inner wall of the crushing tank 4 to crush the gypsum raw materials. The rotation and revolution of the crushing rollers 20 are combined, so that the gypsum raw materials are squeezed and impacted in multiple directions, thereby achieving efficient crushing, reducing energy consumption, and improving production efficiency. Due to the rotation and revolution of the crushing rollers 20, the force on the gypsum raw materials during the crushing process is more uniform, so that the particle size of the crushed products is more uniform, which helps to improve product quality and stability.

[0042] While the turntable 22 rotates, the three scrapers 21 on the turntable 22 rotate with the turntable 22 to clean the inner wall of the crushing tank 4. Cleaning the residual gypsum powder in time during the crushing process can ensure that the inside of the crushing equipment is always clean, which avoids the blockage and agglomeration problems caused by the accumulation of residues, thereby ensuring the continuity and efficiency of the crushing process. The residual gypsum powder may be mixed with new raw materials, resulting in unstable composition and quality of the final product. By cleaning the residue during the crushing process, it can be ensured that each batch of gypsum powder is pure, thereby improving the quality and stability of the product. Regularly cleaning the residual gypsum powder can avoid the equipment from needing additional cleaning and cleaning steps due to blockage, which reduces unnecessary energy consumption and costs and extends the service life of the equipment.

[0043] After the gypsum raw material is crushed, the controller 3 controls the electric telescopic rod 13 to extend, driving the rectangular plate 14 to move upward, and the rectangular plate 14 drives the connecting rod 15 to move, further driving the pipe cover 16 to move upward, and the crushed gypsum powder is discharged through the discharge pipe 12. The electric control discharge device can accurately control the discharge amount of gypsum powder to ensure the accurate material ratio in the production process. This precise control helps to improve the quality and stability of the product. The electric control discharge device adopts electric drive, which can realize automatic control and reduce manual intervention, which can not only improve production efficiency but also reduce labor costs.
