Description

Technical Field

[0001] The present application relates to the technical field of cement product manufacturing, and more specifically, to a raw material screening device for cement product manufacturing. Background Art

[0002] Raw material screening equipment for cement product manufacturing is a device used to classify and screen raw materials. Vibrating screens separate raw materials of different particle sizes to ensure the quality and consistency of cement products. Screening equipment can help optimize raw material ratios, improve production efficiency, and reduce waste.

[0003] However, when the existing raw material screening device is screening raw materials with a large amount of fine particles or high viscosity, the fine or high viscosity particles are easy to block the screening mesh during the screening process, resulting in the powder screen mesh being unable to quickly screen out the raw materials, thereby significantly reducing the screening efficiency and affecting the crushing work efficiency.

[0004] In view of this, we propose a raw material screening device for cement product manufacturing. Utility Model Content

[0012] One or more technical solutions provided in the technical solution of this application have at least the following technical effects or advantages:

[0013] 1. The present application uses the strong wind generated by the fan blades to blow the wind guide plate under the sub-screen, which not only drives the sub-screen to rotate, but also accelerates the screening process of cement raw materials. The rotation of the sub-screen drives the movement of the raw materials, promotes the screening speed, and small particles of cement raw materials can quickly pass through the sub-screen and be exported. The blocking bars on the sub-screen continuously move the cement raw materials, causing them to move irregularly on the sub-screen, further improving the uniformity and comprehensiveness of the screening.

[0014] 2. This application drives the rotating block and the brush bar to rotate by rotating the extension rod. The brush bar can effectively move the particulate dust on the filter screen to prevent the filter screen from being blocked, ensuring the continuous and stable ventilation effect and contributing to the normal operation of the equipment.

It is distributed in a ring shape, and the strong wind generated by the fan blades 13 blows the wind guide plate 14 under the sub-screen 7, which not only drives the sub-screen 7 to rotate, but also accelerates the screening process of raw materials. The rotation of the sub-screen 7 drives the movement of the raw materials, promotes the screening speed, and small particles of cement raw materials can quickly pass through the sub-screen 7 and be exported. The blocking bars 8 on the sub-screen 7 continuously move the cement raw materials, causing them to move irregularly on the sub-screen 7, further improving the uniformity and comprehensiveness of the screening. At the same time, the strong wind blows the materials in the holes of the sub-screen 7, causing the materials in the holes to fall out, thereby preventing the holes of the sub-screen 7 from being blocked, helping to maintain a good screening effect, and avoiding the decrease in processing efficiency due to the blockage of the sub-screen 7.

[0021] Reference Figure 1-Figure 3 One side of the upper end surface of the screening box 1 is fixedly connected with a connected feeding cylinder 2, one side of the outer wall of the screening box 1 is hinged with a discharging door panel 3, one side of the lower end of the screening box 1 is fixedly connected with a fixing plate 4, the upper end surface of the fixing plate 4 is fixedly connected with a guide plate 18, and the lower end surface of the fixing plate 4 is fixedly connected with a supporting base 19. By opening the discharging door panel 3 on the screening box 1, the large particle materials on the sub-screen 7 can be easily cleaned up to ensure that the equipment is always in good working condition.

[0022] Reference Figure 1-Figure 3 The output end of the motor 12 passes through the grid plate 11 and is rotatably connected to the fan blades 13. An extension rod 15 is fixedly connected to the center position of the lower end surface of the sub-screen 7, and one end of the extension rod 15 is fixedly connected to a rotating block 16. The outer wall of the rotating block 16 is symmetrically fixedly connected with a brush strip 17. The bottom of the ventilation frame 9 is fixedly connected to the filter screen 10. The outer wall of the brush strip 17 fits the filter screen 10. The rotation of the extension rod 15 drives the rotating block 16 and the brush strip 17 to rotate. The brush strip 17 can effectively move the particulate dust on the filter screen 10 to prevent the filter screen 10 from being blocked, thereby ensuring the continuous and stable ventilation effect and contributing to the normal operation of the equipment.

[0023] Working principle: The staff pours the cement raw materials into the screening box 1 through the feeding barrel 2, and the cement raw materials fall onto the sub-screen 7 inside the screening box 1, and starts the motor 12 inside the ventilation frame 9. The motor 12 drives the output end to rotate, and the rotation of the output end drives the fan blades 13. The fan blades 13 rotate and blow out strong winds. The strong wind blows the air guide plate 14 under the sub-screen 7. The air guide plate 14 is pushed by the strong wind and drives the sub-screen 7 to rotate. The rotation of the sub-screen 7 will drive the cement raw materials on the sub-screen 7 to rotate, and the cement raw materials will fall with gravity. At the same time, the blocking bars 8 on the sub-screen 7 will continuously move the cement raw materials, causing the cement raw materials to move irregularly, thereby accelerating the screening speed. Small particles of cement raw materials will pass through the sub-screen 7 and fall onto the guide plate 18. The guide plate 18 will guide the small particles of cement raw materials out of the screening box 1, and the staff can collect them. When the sub-screen 7 is blown by a strong wind, the strong wind can blow the materials in the holes of the sub-screen 7, causing the materials in the holes to fall out, thereby avoiding clogging of the holes and affecting the screening effect. At the same time, the rotation of the sub-screen 7 drives the extension rod 15 to rotate, and the rotation of the extension rod 15 drives the rotating block 16 and the brush bar 17 to rotate. The rotation of the brush bar 17 will move the particle dust on the filter 10 to prevent the filter 10 from being blocked and affecting the ventilation effect. After the screening is completed, the discharge door panel 3 on the screening box 1 is opened to clean up the large particles on the sub-screen 7.
