It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a chemical material screening machine, including a top cover 1. A fixed base 12 is fixedly connected to the center of the top surface of the top cover 1. A reduction motor 6 is installed on the top surface of the fixed base 12. Feed inlets 11 are provided on both sides of the fixed base 12 and are fixedly connected to the top surface of the top cover 1. Screening boxes 2 are fixedly connected to the bottom surface of the top cover 1. Three screening boxes 2 are provided and are fixedly connected to each other. A bottom plate 4 is fixedly connected to the bottom surface of the screening boxes 2. Discharge pipes 3 are fixedly connected to the outer walls of the three screening boxes 2. A discharge pipe 3 is provided below the bottom plate 4. The screen has a base 5, and a spring 42 is fixedly connected between the top surface of the base 5 and the base plate 4. A vibrating motor 43 is fixedly connected to the center of the bottom surface of the base plate 4. A fixed screen 7 is fixedly connected to the inner wall of the screening box 2. A movable screen 8 is set on the bottom surface of the fixed screen 7. The screen hole diameter of the three fixed screens 7 gradually decreases from top to bottom. The adjacent fixed screens 7 and movable screens 8 have the same hole diameter. A drive shaft 61 is connected through the center of the top surface of the fixed screen 7. The top end of the drive shaft 61 is fixedly connected to the output shaft end of the reduction motor 6. The movable screen 8 is fixedly connected and sleeved on the outer wall of the drive shaft 61.
[0023] The specific settings and effects of the embodiment are described below. The vibration motor 43 is started to cooperate with the spring 42 to vibrate the screening box 2 to make the material pass through the fixed screen 7 and the movable screen 8 inside the screening box 2 for screening. Three groups of screening boxes 2 are used to perform multi-stage screening on the material. In the continuous screening process, the reduction motor 6 is intermittently started to drive the transmission shaft 61 to drive the movable screen 8 to rotate periodically. The shear effect is generated by the mutual rotation between the fixed screen 7 and the movable screen 8. The shear effect can prevent the fixed screen 7 from being blocked to some extent. When the material has a tendency to block the screen holes, the shear force can push away or break the blocked material to keep the screen holes unblocked.

The partition plate 33 is connected through the top surface of the discharge pipe 3. The bottom end of the partition plate 33 is movably connected with the inner wall of the discharge pipe 3.
[0025] The effect of the whole embodiment is that the screened material is discharged through the discharge pipe 3 and the bottom discharge pipe 44. The user controls the partition plate 33 to rise and fall through the electric cylinder 31 and the traction plate 32, so as to conveniently control the on-off of the material in the discharge pipe 3 and control the discharge of the screened material.
[0026] The use method and working principle of the device are as follows. When in use, the user puts the chemical material into the screening box 2 through the feeding port 11. The vibration motor 43 is started to cooperate with the spring 42 to vibrate the screening box 2 to make the material pass through the fixed screen 7 and the movable screen 8 inside the screening box 2 for screening. Three groups of screening boxes 2 are used to perform multi-stage screening on the material. The screened material is discharged through the discharge pipe 3 and the bottom discharge pipe 44. In the continuous screening process, the reduction motor 6 is intermittently started to drive the transmission shaft 61 to drive the movable screen 8 to rotate periodically. The shear effect is generated by the mutual rotation between the fixed screen 7 and the movable screen 8. The shear effect can prevent the fixed screen 7 from being blocked to some extent. When the material has a tendency to block the screen holes, the shear force can push away or break the blocked material to keep the screen holes unblocked. The user controls the partition plate 33 to rise and fall through the electric cylinder 31 and the traction plate 32, so as to conveniently control the on-off of the material in the discharge pipe 3 and control the discharge of the screened material.
