Description

Technical Field

[0001] This utility model relates to the field of screening technology, and in particular to a multi-stage vibrating screening device for glass powder that prevents clogging. Background Technology

[0002] In the production and processing of glass powder materials, the screening process is a key step in controlling particle size distribution, removing impurities, and optimizing product performance.

[0003] In existing glass powder screening equipment, the high surface energy of the glass powder makes it easy for it to adhere to the screen mesh due to electrostatic adsorption or interparticle friction. When the screen body vibrates as a whole, the glass powder on the screen surface cannot gain enough kinetic energy to detach from the mesh. After prolonged clogging, the machine needs to be stopped and the screen needs to be cleaned manually, which not only increases maintenance costs but also affects the continuity of production. Therefore, we propose a multi-stage vibrating screening device for glass powder that prevents clogging. Utility Model Content

This device can solve the problem that in the process of using existing glass powder sieve equipment, the glass powder has a high surface energy and is easily adhered to the screen mesh due to electrostatic adsorption or inter-particle friction. When the screen body vibrates as a whole, the glass powder on the screen surface is difficult to obtain enough kinetic energy to detach from the mesh. After a long period of clogging, the machine needs to be stopped and the screen needs to be cleaned manually, which not only increases maintenance costs but also affects the continuity of production.

[0027] Please see Figure 1-5 This utility model provides a technical solution: a multi-stage vibrating sieve device for preventing clogging of glass powder, comprising:

[0028] Vibrating screen box 1 and support platform 3, the vibrating screen box 1 is slidably installed inside the support platform 3, and the support platform 3 is provided with a vibrating structure;

[0029] Screen plate anti-clogging structure, the screen plate anti-clogging structure is located on the vibrating screening box 1;

[0030] The screen plate anti-clogging structure includes three screening screen plates 6, three rotating shafts 15, and three cams 16. The three screening screen plates 6 are fixedly installed in a stepped manner inside the vibrating screening box 1. Three partitions 14 are fixedly connected inside the vibrating screening box 1. The three partitions 14 are all located at the bottom of the corresponding screening screen plates 6. The three rotating shafts 15 are all rotatably connected inside the vibrating screening box 1. One end of each of the three rotating shafts 15 extends rotatably to the outside of the vibrating screening box 1. The three cams 16 are all fixedly sleeved on the outer surface of the corresponding rotating shafts 15.

[0031] The screen plate anti-clogging structure also includes three pulleys 17, two belts 18, a rotating motor 12, and a mounting frame 13. The mounting frame 13 is fixedly connected to one side of the vibrating screen box 1. The rotating motor 12 is fixedly installed on the side of the mounting frame 13 away from the vibrating screen box 1. The output end of the rotating motor 12 rotates through the mounting frame 13 and is fixedly connected to the corresponding rotating shaft 15. The three pulleys 17 are all fixedly sleeved on the outer surface of the corresponding rotating shaft 15, and the two belts 18 are all driven sleeved on the outer surface of the corresponding two pulleys 17.

[0032] Each of the three cams 16 is rotatably connected to multiple rotating rods 19.

[0033] The vibrating structure includes two fixed plates 4, a support base 7, a drive motor 8, and a cam 9. The two fixed plates 4 are fixedly connected to both sides of the vibrating screening box 1, the support base 7 is fixedly connected to the top of the support platform 3, the drive motor 8 is fixedly installed on the top of the support base 7, and the output end of the drive motor 8 is fixedly connected to the cam 9. Multiple springs 5 ​​are fixedly connected to the top of the support platform 3, and the top ends of the multiple springs 5 ​​are fixedly connected to the bottom of the corresponding fixed plates 4.

[0034] Three collection boxes 2 are slidably connected inside the vibrating screening box 1. All three collection boxes 2 are located below the corresponding screening screen plate 6. A discharge port 11 is opened on the side of the vibrating screening box 1 away from the mounting frame 13. A guide plate 10 is fixedly connected inside the vibrating screening box 1. One side of the guide plate 10 is in contact with the corresponding screening screen plate 6.

[0035] Furthermore, when using this device, the glass powder to be screened is poured into the screening screen plate 6 at the top of the vibrating screening box 1. The glass powder first falls onto the uppermost screening screen plate 6. The drive motor 8 is started, and the drive motor 8 drives the cam 9 to rotate. During the rotation, the cam 9 will periodically push up the fixed plate 4 on one side of the vibrating screening box 1. Since the vibrating screening box 1 is slidably installed in the support platform 3, and the top of the support platform 3 is connected to the fixed plate 4 through multiple springs 5, the vibrating screening box 1 will vibrate up and down under the pushing action of the cam 9 and the elastic recovery action of the springs 5. This vibration causes the glass powder to jump and move continuously on the screening screen plate 6. Glass powder particles smaller than the aperture of the screening screen plate 6 will fall into the collection box 2 below through the screen holes, while glass powder particles larger than the screen holes will move along the screening screen plate 6 towards the discharge port 11.

[0036] Since the three screening screen plates 6 are fixedly installed in the vibrating screening box 1 in a stepped manner, and the aperture of each screening screen plate 6 is different, with the aperture gradually decreasing from top to bottom, the glass powder will pass through the screening screen plates 6 with different apertures in sequence for screening. Glass powder of different particle sizes will fall into the corresponding collection box 2 respectively, realizing multi-stage precise screening. The height of the three partition plates 14 gradually decreases, and the length of the three rotating shafts 15 gradually increases.

[0037] During the vibrating screening process, the rotating motor 12 is started, which drives the rotating shaft 15 connected to it to rotate. The pulley 17 on the rotating shaft 15 drives the other two rotating shafts 15 to rotate synchronously through the belt 18, thereby causing the cams 16 on the three rotating shafts 15 to rotate simultaneously. During the rotation, the cams 16 periodically strike the corresponding screening screen plates 6. Since the three screening screen plates 6 are made of metal with a certain degree of elasticity, the screening screen plates 6 will produce slight vibration and shaking, which effectively prevents glass powder from clogging the screen holes and ensures the smooth progress of the screening process. The rotating rod 19 on the screening screen plate 6 can reduce the friction between the cams 16 and the screening screen plate 6. After screening, large glass powder particles that do not pass through the bottom screening screen plate 6 will be discharged from the discharge port 11 under the guidance of the guide plate 10, and can be further processed or reprocessed.

[0038] The rotating motor 12 drives three rotating shafts 15 and cam 16 to rotate, causing the rotating rod 19 to periodically strike the screening screen plate 6, providing additional vibration and shaking force to the screening screen plate 6. This allows the glass powder adhering to the screen holes to gain sufficient kinetic energy to detach from the screen holes, effectively preventing screen blockage, reducing the number of times the machine needs to be stopped to clean the screen, ensuring the continuity of the screening process, and further improving screening efficiency.
