Description

Technical Field

[0001] This utility model relates to the field of petroleum coke grinding, specifically to a petroleum coke grinding and forming device. Background Technology

[0002] Petroleum coke is a black or dark gray hard solid petroleum product with a metallic luster and is porous. It comes in various shapes, including powder, block, granular, honeycomb, and spherical. The pores inside the coke block are mostly elliptical and interconnected.

[0003] Petroleum coke needs to be ground by a grinding mill during processing. However, some of the ground material still does not meet the required particle size, so it needs to be screened again and then ground a second time. This greatly increases the number of petroleum coke grinding and processing steps and reduces grinding efficiency. Therefore, there is an urgent need for a device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a petroleum coke grinding and forming device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a petroleum coke grinding and forming device, comprising a grinder, a support frame fixedly mounted on the outside of the grinder, a transport mechanism for facilitating the transport of substandard fragments on one side of the support frame, a movable rod movably inserted on the support frame, a screen fixedly mounted on the outside of the movable rod, a baffle fixedly mounted on the top of the screen, a fixed block fixedly mounted on one side of the movable rod, a spring fixedly mounted between the fixed block and the support frame, a motor fixedly mounted on the top of the support frame, and a cam fixedly mounted at the output end of the motor. During use, the raw material is ground and pulverized by the grinder, and then discharged into the top of the screen through the discharge port. Simultaneously, the motor is started, driving the cam to rotate. The cam's protruding end presses against the fixed block, causing the movable rod to move, thus compressing the spring. After the protruding end moves away from the fixed block, the spring drives the movable rod to return to its original position. This causes the screen to move repeatedly, improving screening efficiency.

[0006] Preferably, the conveying mechanism includes a collection box, a screw conveyor, and a discharge pipe. The screw conveyor is fixed to one side of the support frame, the collection box is embedded and fixed at the inlet of the screw conveyor, the protruding end of the screen extends into the inside of the collection box, and the discharge pipe is embedded and fixed to one side of the screw conveyor. During use, unqualified fragments fall into the collection box under the guidance of the baffle under the action of gravity, and then enter the screw conveyor. After being transported, they are discharged into the grinder through the discharge pipe. This automatic screening eliminates the need for additional manual operation, greatly facilitating the grinding and pulverizing process.

[0007] Preferably, the cross-section of the movable rod is a regular polygon.

[0008] Preferably, the screen is located at the lower end of the grinder discharge port.

[0009] Preferably, one side of the cam is in close contact with one side of the fixed block, and the screen is convex in shape.

[0010] Preferably, the discharge pipe is located at the feed inlet at the top of the grinder.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. When using this utility model, the raw material is ground and crushed by the grinder, and then discharged into the top of the screen through the discharge port. At the same time, the motor is started, and the motor drives the cam to rotate. The cam's convex end presses against the fixed block, which drives the movable rod to move, so that the spring is compressed. After the convex end moves away from the fixed block, the spring drives the movable rod to return to its original position. In this way, the screen moves repeatedly, improving the screening efficiency.

[0013] 2. In use, the unqualified fragments are guided by the baffle under the action of gravity and fall into the collection box. Then they enter the screw conveyor and are discharged into the grinder through the discharge pipe. This automatic screening eliminates the need for manual operation and greatly facilitates the grinding and crushing process. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3This utility model provides a petroleum coke grinding and forming device, including a grinder 1. A support frame 2 is bolted to the outside of the grinder 1. A conveying mechanism for transporting substandard crushed material is located on one side of the support frame 2. A movable rod 8 is movably inserted on the support frame 2. The movable rod 8 has a regular polygonal cross-section. A screen 6 is bolted to the outside of the movable rod 8. The screen 6 is located at the lower end of the discharge port of the grinder 1. A baffle 5 is welded to the top of the screen 6. A fixing block 9 is welded to one side of the movable rod 8. A spring 10 is welded to the fixing block 9 and the support frame 2. A spring 10 is welded to the top of the support frame 2. The mounting bracket is fixed with a motor 12. The output end of the motor 12 is fixed with a cam 11 via a coupling. One side of the cam 11 is in close contact with the side of the fixed block 9. The screen 6 is convex in shape. During use, the raw material is ground and crushed by the grinder 1 and then discharged into the top of the screen 6 through the discharge port. At the same time, the motor 12 is started, and the motor 12 drives the cam 11 to rotate. The convex end of the cam 11 presses against the fixed block 9, which drives the movable rod 8 to move, so that the spring 10 is compressed. After the convex end moves away from the fixed block 9, the spring 10 drives the movable rod 8 to return to its original position. In this way, the screen 6 moves repeatedly, improving the screening efficiency.

[0020] The transport mechanism includes a collection box 7, a screw conveyor 3, and a discharge pipe 4. The screw conveyor 3 is fixed to one side of the support frame 2 by bolts. The collection box 7 is embedded and fixed at the inlet of the screw conveyor 3. The protruding end of the screen 6 extends into the inside of the collection box 7. The discharge pipe 4 is embedded and fixed to one side of the screw conveyor 3. The discharge pipe 4 is located at the inlet of the top of the grinder 1. During use, the unqualified crushed material is guided by the baffle 5 under the action of gravity and falls into the collection box 7. Then it enters the screw conveyor 3. After being transported, it is discharged into the grinder 1 through the discharge pipe 4. In this way, the screening is performed automatically without the need for additional manual operation, which greatly facilitates the grinding and crushing work.

[0021] Working principle: During use, the raw material is ground and crushed by the grinder 1, and then discharged into the top of the screen 6 through the discharge port. At the same time, the motor 12 is started, and the motor 12 drives the cam 11 to rotate. The convex end of the cam 11 presses against the fixed block 9, which drives the movable rod 8 to move, so that the spring 10 is compressed. After the convex end moves away from the fixed block 9, the spring 10 drives the movable rod 8 to return to its original position. In this way, the screen 6 moves repeatedly, improving the screening efficiency. During use, the crushed material that fails to meet the screening requirements falls into the collection box 7 under the guidance of the baffle 5 under the action of gravity, and then enters the screw conveyor 3. After being transported, it is discharged into the grinder 1 through the discharge pipe 4. In this way, the screening is carried out automatically without the need for additional manual operation, which greatly facilitates the grinding and crushing work.
