Description

Technical Field

[0001] This utility model relates to the field of carbon material processing technology, specifically to a rapid feeding device for a sand mill used in carbon processing. Background Technology

[0002] A sand mill is an important processing machine in the processing of carbon materials. It is generally used to further grind and crush carbonized materials to achieve the target particle size. In use, conveyor belts, elevators, and other conveying devices are usually used to feed the raw materials into the hopper of the sand mill. The screw conveyor located below the hopper then transports the raw materials quantitatively and periodically into the sand mill for grinding.

[0003] However, in practical applications, we have found that due to differences in the characteristics of raw materials, some carbonized raw materials with smaller particle size and higher consistency are prone to compaction and blockage at the bottom of the hopper, resulting in poor feeding of the screw conveyor. In many cases, it is necessary to manually pry up the material and turn it over, which affects the overall working efficiency of the sand mill. Summary of the Invention

[0004] The purpose of this invention is to provide a rapid feeding device for a sand mill used in carbon processing that can prevent raw material compaction and automatically flip the bottom.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is: a rapid feeding device for a sand mill for carbon treatment, comprising a hopper and a screw conveyor disposed below the hopper; the inlet of the screw conveyor is connected to the outlet at the bottom of the hopper;

[0006] A pair of side holes are symmetrically arranged on both sides of the discharge port, and an elastic rubber sealing plate is installed in the side hole; a lifting rod extending laterally through the elastic rubber sealing plate is also installed in the side hole, one end of the lifting rod is connected to the drive assembly, and can move up and down in the discharge port under the drive of the drive assembly.

[0007] Preferably, two U-shaped guide forks are provided on both sides of the discharge port, and the lifting rod is located at the fork of the guide fork and cooperates with the lifting rod, and is locked outside the lifting rod.

[0008] Preferably, the guide fork is mounted on top of the screw conveyor via a fork seat at the bottom.

[0009] Preferably, the drive assembly includes a contact plate disposed at the end of the lifting rod and an eccentric plate fixedly disposed on the drive shaft of the screw conveyor, wherein the eccentric plate is positioned opposite to the contact plate and the two are in contact with each other.

[0010] The beneficial effects of this invention are mainly reflected in its ability to effectively prevent material from compacting and caking at the bottom of the hopper, ensuring smooth material discharge from the hopper and feeding into the screw conveyor. Specifically, during use, the lifting rod moves up and down within the discharge port under the drive of the drive assembly, thereby overturning the raw material accumulated at the bottom of the hopper discharge port, preventing material compaction and caking. The loose material enters the screw conveyor from the discharge port and is then conveyed into the sand mill. This ensures smooth feeding into the screw conveyor and prevents increased load on the screw conveyor due to compaction. It has positive implications for improving feeding stability, feeding efficiency, and equipment lifespan. Attached Figure Description

[0012] Figure 2 This is a schematic diagram of the guide fork structure;

[0013] Figure 3 This is a schematic diagram of the drive component. Detailed Implementation

[0014] like Figure 1-3 As shown, a rapid feeding device for a sand mill used in carbon treatment is similar to a conventional sand mill feeding device, also including a hopper 1 and a screw conveyor 2 disposed below the hopper 1. The inlet of the screw conveyor 2 is connected to the outlet 3 at the bottom of the hopper 1, and the outlet is connected to the inlet of the sand mill, for conveying materials into the sand mill.

[0015] The most distinctive feature of this invention is that a pair of side holes 4 are symmetrically arranged on both sides of the discharge port 3. A horizontally extending lifting rod 6 is also provided inside the side holes 4. The side holes 4 are generally vertical strip holes to allow the lifting rod 6 to move up and down, but large-sized round holes can also be used. In order to block and contain the side holes 4 without affecting the up and down movement of the lifting rod 6, an elastic rubber sealing plate 5 is provided inside the side holes 4, and the lifting rod 6 passes through the elastic rubber sealing plate 5.

[0016] One end of the lifting rod 6 is connected to the drive assembly and can move up and down within the discharge port 3 under the drive of the drive assembly. The drive assembly can have various structural forms; for example, it can be an eccentric wheel located on the drive circumference plus a pulley located at the end of the lifting rod 6 and connected to the eccentric wheel via a transmission belt. As the eccentric wheel rotates, it pulls the pulley up and down, thus achieving lifting. Alternatively, it can be as follows... Figure 3As shown, the drive assembly includes a contact plate 9 disposed at the end of the lifting rod 6, and an eccentric plate 10 fixedly disposed on the drive shaft of the screw conveyor 2. The eccentric plate 10 is positioned opposite the contact plate 9, and the two are in contact with each other. The protruding portion of the eccentric plate 10 pushes the contact plate 9, thereby driving the lifting rod 6 to move up and down.

[0017] During use, the lifting rod 6 moves up and down within the discharge port 3 under the drive of the drive assembly, thereby overturning and arching the raw materials accumulated in the discharge port 3 at the bottom of the hopper 1, preventing the material from becoming compacted and caking. The loose material enters the screw conveyor 2 from the discharge port 3 and is then conveyed into the sand mill by the screw conveyor 2. This ensures smooth feeding of the screw conveyor 2 and prevents increased load on the screw conveyor 2 due to compaction. It has positive significance for improving feeding stability, feeding efficiency, and equipment lifespan.

[0018] Based on this, in order to further improve the movement stability of the lifting rod 6, this utility model also provides two U-shaped guide forks 7 on both sides of the discharge port 3. The lifting rod 6 is located at the fork opening of the guide fork 7 and cooperates with the lifting rod 6, and is locked outside the lifting rod 6. Generally, the guide fork 7 is installed on the top of the screw conveyor 2 through the fork seat 8 at the bottom.
