Description

Technical Field

[0001] The invention relates to the technical field of screening, in particular to a screening device for processing porous graphite raw materials. Background Art

[0002] When processing porous graphite, the raw materials need to be ground into fine powder in advance and then mixed. The ground raw materials will still be mixed with raw materials with larger particles, which need to be screened by screening equipment. Existing screening equipment, such as a graphite production raw material screening device disclosed by authorization announcement No. CN219560472U, is equipped with a scraper. The No. 1 motor generates kinetic energy through working operation and provides it to the output end rotating shaft. The rotating shaft rotates inside the protective shell through the kinetic energy provided by the No. 1 motor. The rotating shaft is connected to the scraper through a through-meshing connection. The scraper moves through the inner wall of the screening box and contacts the top of the screen through the scraper. The scraper can move to push and clear the graphite raw material blocked inside the screen, effectively solving the problem that the graphite raw material is easy to block the screen, and effectively improving the screening efficiency of the screening device.

[0003] At present, when screening graphite raw materials, they are generally screened through a screen to screen out raw materials with larger particles. Similar to the above-mentioned prior art, the problem of screen blockage is avoided by contacting the scraper with the top of the screen. However, during the screening process, some raw materials with moderate particles may be stuck in the screen, causing the screen to be blocked. The blockage is not entirely caused by powdered raw materials. At this time, the contact between the scraper and the screen may squeeze the raw materials with moderate particles and cause them to leak out of the screen. However, the raw materials in this state do not meet the specifications and may need to be screened again, which is more troublesome. Summary of the invention

A disc 15 at one end of a rotating gear 16, a circular groove 20 is provided on the outer side of the screening box 1, and a plurality of bayonet holes 21 are provided on the inner wall of the circular groove 20. A plurality of arc-shaped blocks 22 corresponding to the positions of the bayonet holes 21 are fixedly installed on the outer side of the disc 15. The arc-shaped blocks 22 are elastic blocks. When the motor 3 is working, it can be used to control the rotating gear 16 meshing with the fixed gear ring 13 to rotate in only one direction, and then to control the screw feeder 4 to rotate in the opposite direction to the conveying drum 5. The diameter of the rotating gear 16 is consistent with the outer diameter of the rotating gear ring 17 and the outer diameter of the fixed gear ring 13, so as to ensure that the screw feeder 4, the rotating drum 7 and the conveying drum 5 are controlled to rotate synchronously;

[0035] When the conveying drum 5 rotates, the discharge port 30 is driven to move, and can be used to convey the materials to the rotating drum 7 in a dispersed manner.

[0036] As a further technical solution of the present invention, protective shells 8 for protecting the reciprocating components are fixedly installed on both sides of the screening box 1, the connecting frame 9 is slidably connected to the protective shells 8, the feed shell 2 is fixedly connected to one of the protective shells 8, the conveying cylinder 5 is rotatably connected to the protective shell 8, the output end of the motor 3 is rotatably connected to the other protective shell 8, and the rotating gear ring 17 and the fixed gear ring 13 are both located in the protective shells 8 at corresponding positions.

[0037] Working principle: Pour the crushed raw material into the circular shell 31 through the feed shell 2, and then start the motor 3 to work. The motor 3 drives the screw feeder 4 to rotate and transfer the material to the discharge port 30, and then leak into the drum 7. When the discharge port 30 opens downward, the screen 12 is also located below. At this time, the raw material leaks through the screen 12, and the granular raw materials that do not meet the specifications still remain in the drum 7;

[0038] The screw feeder 4 rotates to drive the rotating gear ring 17 to rotate, and at the same time drives the drum 7 to rotate through the connecting rod 10 (the discharge port 30 and the screen 12 move from bottom to top at the same time), the rotating gear ring 17 drives the rotating gear 16 connected thereto to rotate, the rotating gear 16 drives the sliding rod 19 connected thereto to move, the sliding rod 19 drives the rectangular frame 18 connected thereto to move downward, the rectangular frame 18 drives the connecting frame 9 to move downward, and the connecting frame 9 drives the arc-shaped striking plate 11 and another rectangular frame 18 to move downward;

[0039] When the screen 12 rotates upward, the arc-shaped striking plate 11 moves downward to hit the screen 12, so that the material blocked in the screen 12 is knocked into the rotary drum 7, which can solve the blockage problem and prevent the raw material particles that do not meet the specifications from leaking out;

[0040] Another rectangular frame 18 moves downward to drive the slide bar 19 connected thereto to move, and the slide bar 19 drives the rotating gear 16 connected thereto to rotate. Due to the restrictions of the bayonet 21 and the elastic arc-shaped block 22, the rotating gear 16 can only rotate in one direction. The rotating gear 16 drives the fixed gear ring 13 to rotate, and the fixed gear ring 13 drives the conveying drum 5 to rotate. The conveying drum 5 rotates in the opposite direction to the screw feeder 4.

[0041] When the conveying drum 5 rotates, the discharge port 30 is driven to move, and can be used to convey the dispersed materials to the rotating drum 7;

[0042] When the conveying cylinder 5 rotates, it drives the connecting shell 27 to move. When the connecting gear 29 is meshed with the arc-shaped tooth plate 28, the extrusion roller 6 rolls on the inside of the rotating cylinder 7, and the large-particle raw materials can be crushed. When the connecting gear 29 is meshed with the vertical tooth plate 14, the control slider 26 drives the extrusion roller 6 to shrink and not contact the screen 12, so as to avoid squeezing out the raw material particles that do not meet the specifications stuck in the screen 12.

Although the present invention has been described in detail with reference to the above embodiments, it is obvious to those skilled in the art that the features thereof are equivalently replaced.
