Description

Technical Field

[0001] The utility model relates to the technical field of coal powder processing, and more specifically, to a novel coal powder particle screening device. Background Art

[0002] Particle characteristics: Coal powder is composed of particles of different sizes and irregular shapes. Generally, the diameter of coal powder particles ranges from 0-1000um, and most of them are 20-50um particles. Coal powder has fluidity. Coal powder particles are very fine, and the unit mass of coal powder has a large surface area. The surface can absorb a large amount of air, making it fluid.

[0003] During the coal powder processing, operators often use corresponding coal powder particle screening devices to screen the coal powder particles. In actual use, although the existing screening devices have basic screening functions, general screening devices can only perform screening operations of the same size. When the screening size needs to be changed, the operator usually disassembles and replaces the screen, which not only reduces the application scope of the device, but also increases the labor intensity of the operator. Therefore, improvement is needed. Utility Model Content

[0043] When the first gear 26 rotates, the second gear 27 drives the rotating rod 28 and the hopper 29 to rotate.

[0044] The working principle and use process of this utility model:

[0045] First, the pulverized coal particles to be screened are added to the interior of the hopper 29 through the inclined plate 3, and then the drive motor 24 is started, so that the No. 2 rotating shaft 25 drives the No. 1 gear 26 to rotate, and the No. 2 gear 27 drives the rotating rod 28 to rotate, so that the hopper 29 starts to rotate, so that it can rotate and discharge materials to the top of the first screening roller 10 and the second screening roller 22, thereby achieving the purpose of uniform feeding and improving the screening effect of the device. Subsequently, the first motor 9 and the power motor 21 are started, and the first screening roller 10 and the second screening roller 22 start to rotate respectively. At this time, the screening operation will be carried out, and finally the large particles that do not meet the screening size will fall into the interior of the collecting box 30 under the rotation of the first screening roller 10 and the second screening roller 22 rotating in the same direction, and the small particles that meet the size requirements will fall on the top of the material belt 17.

[0046] When the screening operation begins, starting the second motor 14 will cause the No. 1 rotating shaft 15 to drive the sleeve rod 16 to start rotating, and the material belt 17 will drive the rotating rod 19 to start rotating. The screened small particles will be transported out of the device through the material belt 17, which is convenient for the operator's collection operation. When the initial screening size of the device is large and does not meet the demand, starting the pneumatic cylinder 4 will cause the movable plate 5 to drive the rectangular block 6 to move upward under the limiting action of the inclined slot 2, and the inclined rod 7 will start to move. At this time, the four No. 1 motor housings 8 will move toward each other in pairs, so that the first screening roller 10 drives the first limiting block 11 and the second limiting block 32 to move to the right under the limiting action of the rectangular slot 12 and the limiting slot 31 respectively, and finally reduces the distance between the first screening roller 10 and the second screening roller 22, thereby achieving the purpose of adjusting the screening size and improving the application range of the device.
