A grinding mechanism for coal powder production

Abstract

This utility model discloses a grinding mechanism for coal powder production, belonging to the technical field of coal powder production and processing equipment. The grinding mechanism includes a base box and a fixed bucket fixedly installed on the base box. Through the coordinated use of these devices, coal blocks are placed into the fixed bucket and ultimately fall into the grinding bucket. The rotating shaft drives the grinding balls, connecting rod, and upper gear ring to rotate together. Since the upper gear ring meshes with a gear, and the gear meshes with a lower gear ring, the rotation of the upper gear ring drives the gear to rotate, which in turn drives the reciprocating screw and the grinding bucket to rotate around the rotating connection position of the connecting frame. Simultaneously, the reciprocating screw inside the rotating box also rotates, causing the grinding bucket to reciprocate within the rotating box. The rotation and reciprocating sliding of the grinding bucket, combined with the rotation of the grinding balls, achieve efficient grinding of the coal blocks, effectively reducing clogging, improving grinding quality, and thus increasing production efficiency.

Description

Technical Field

[0001] This utility model relates to the technical field of coal powder production and processing equipment, specifically a grinding mechanism for coal powder production. Background Technology

[0002] Coal is a commonly used chemical raw material in the chemical industry. Its production and processing involves multiple stages such as grinding and transportation. Lump coal needs to be ground into powder before it can enter the next processing stage. Therefore, coal powder grinding equipment is particularly important.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN218167327U) discloses a high-efficiency grinding device for coal powder processing, comprising a silo body, a screening component mounted on the silo body, a grinding component connected to the screening component inside the silo body, a flow guide chamber with one end penetrating through and fixedly connected to the inner peripheral wall of the silo body fixedly installed at the bottom of the silo body, the screening component including a motor fixedly installed at the top of the silo body, a screw with one end penetrating through and extending into the silo body fixedly installed at the output end of the motor, an adjusting plate fixedly installed on the outer peripheral wall of the screw, and two connecting rods fixedly installed at the bottom of the adjusting plate, with the two connecting rods located on the left and right sides of the screw.

[0004] In the aforementioned patent, starting the motor causes the screw to rotate forward or reverse, which in turn drives the fixed rod to rotate, thereby causing the grinding balls to rotate and rapidly grind the material in conjunction with the grinding plates. However, coal lumps may clog above the grinding balls, and there are also problems such as poor grinding quality and insufficient grinding, which require repeated grinding and thus affect production efficiency.

[0005] Therefore, this utility model provides a grinding mechanism for coal powder production to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved This invention provides a grinding mechanism for coal powder production, aiming to solve the problems mentioned in the background art.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a grinding mechanism for coal powder production, which includes a bottom box, a fixed barrel fixedly installed on the bottom box, a top plate fixedly installed on the fixed barrel, and a grinding mechanism disposed inside the fixed barrel for grinding coal blocks.

[0008] The grinding mechanism includes a rotating shaft rotatably installed inside the fixed barrel, a grinding ball fixedly installed at the bottom end of the rotating shaft, a connecting rod fixedly installed on the side surface of the rotating shaft, an upper gear ring fixedly installed on the end of the connecting rod away from the rotating shaft, a lower gear ring fixedly installed on the inner wall of the fixed barrel, a connecting frame fixedly installed on the lower gear ring, a rotating box rotatably installed on the connecting frame, a reciprocating screw rotatably installed inside the rotating box, a gear fixedly installed on one end of the reciprocating screw, and a grinding barrel screwed to the reciprocating screw.

[0009] As a preferred technical solution of this application, the grinding ball is disposed inside the grinding barrel, the upper toothed ring meshes with the gear, the gear meshes with the lower toothed ring, and the grinding barrel is slidably connected inside the rotating box.

[0010] As a preferred technical solution of this application, a crushing barrel is fixedly connected to the inner wall of the fixed barrel, an electric heating wire is fixedly connected to the side surface of the crushing barrel, and a motor is fixedly connected to the top of the top plate.

[0011] As a preferred technical solution of this application, the movable end of the motor passes through the top plate and is fixedly connected to the top end of the rotating shaft, and a crushing rod is fixedly connected to the side surface of the rotating shaft.

[0012] As a preferred technical solution of this application, a plurality of crushing rods are provided, and the crushing rods are arranged in a linear array on the rotating shaft. A filter plate is fixedly connected to the bottom of the crushing barrel, and the filter plate is located directly above the grinding barrel.

[0013] As a preferred technical solution of this application, a collection box is slidably connected inside the bottom box, and a handle is fixedly connected to one side of the collection box.

[0014] (III) Beneficial Effects This utility model has a simple structure and is easy to use. Through the setting of the grinding mechanism, coal blocks are placed into a fixed bucket and finally fall into the grinding bucket. The driving shaft rotates, and the shaft drives the grinding balls, connecting rod and upper gear ring to rotate together. Since the upper gear ring meshes with the gear, and the gear meshes with the lower gear ring, the rotation of the upper gear ring drives the gear to rotate, which in turn drives the reciprocating screw and the grinding bucket to rotate around the rotating connection position of the connecting frame. At the same time, the reciprocating screw in the rotating box also rotates, so that the grinding bucket reciprocates and slides in the rotating box. The rotation and reciprocating sliding of the grinding bucket, combined with the rotation of the grinding balls, together achieve efficient grinding of coal blocks, effectively reduce clogging, improve grinding quality, and thus improve production efficiency.

Detailed Implementation

[0017] 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.

[0018] This utility model provides a grinding mechanism for coal powder production, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the grinding mechanism for coal powder production includes a bottom box 1, a fixed bucket 2 fixedly installed on the bottom box 1, a top plate 3 fixedly installed on the fixed bucket 2, and a grinding mechanism set inside the fixed bucket 2 for grinding coal blocks.

[0019] The grinding mechanism includes a rotating shaft 4 rotatably installed inside the fixed barrel 2, a grinding ball 5 fixedly installed at the bottom end of the rotating shaft 4, a connecting rod 6 fixedly installed on the side surface of the rotating shaft 4, an upper toothed ring 7 fixedly installed on the end of the connecting rod 6 away from the rotating shaft 4, a lower toothed ring 8 fixedly installed on the inner wall of the fixed barrel 2, a connecting frame 9 fixedly installed on the lower toothed ring 8, a rotating box 10 rotatably installed on the connecting frame 9, a reciprocating screw 11 rotatably installed inside the rotating box 10, a gear 12 fixedly installed on one end of the reciprocating screw 11, and a grinding barrel 13 screwed onto the reciprocating screw 11.

[0020] Grinding balls 5 are placed inside grinding barrel 13. Upper toothed ring 7 meshes with gear 12, gear 12 meshes with lower toothed ring 8, and grinding barrel 13 is slidably connected inside rotating box 10.

[0021] When using this coal powder grinding mechanism, the bottom box 1 is first placed in a suitable position, then the coal block is placed into the fixed bucket 2, and finally falls into the grinding bucket 13. Then, the rotating shaft 4 is driven to rotate, which drives the grinding ball 5 and the connecting rod 6 to rotate together. The upper toothed ring 7 on the connecting rod 6 rotates accordingly. Since the upper toothed ring 7 meshes with the gear 12, and the gear 12 meshes with the lower toothed ring 8, the upper toothed ring 7 will drive the gear 12 to rotate. The gear 12 drives the reciprocating screw 11 and the grinding bucket 13 to rotate around the position where it is rotatably connected to the connecting frame 9. The reciprocating screw 11 inside the rotating box 10 rotates accordingly, which causes the reciprocating screw 11 to drive the grinding bucket 13 screwed to the reciprocating screw 11 to slide back and forth inside the rotating box 10. The reciprocating sliding of the grinding bucket 13 and the rotation of the grinding ball 5 combine to efficiently grind the coal block.

[0022] Furthermore, in order to pre-treat the coal, such as... Figure 1 , Figure 2 and Figure 3 As shown, a crushing barrel 14 is fixedly connected to the inner wall of the fixed barrel 2, an electric heating wire 17 is fixedly connected to the side surface of the crushing barrel 14, and a motor 15 is fixedly connected to the top of the top plate 3.

[0023] The movable end of the motor 15 passes through the top plate 3 and is fixedly connected to the top of the rotating shaft 4. A crushing rod 16 is fixedly connected to the side surface of the rotating shaft 4.

[0024] Multiple crushing rods 16 are provided and are arranged in a linear array on the rotating shaft 4. A filter plate 18 is fixedly connected to the bottom of the crushing barrel 14 and is positioned directly above the grinding barrel 13.

[0025] When the grinding mechanism for coal powder production is in use, after the motor 15 is started, its movable end drives the rotating shaft 4 to rotate, and the crushing rod 16 on the rotating shaft 4 rotates accordingly, which initially crushes the coal blocks that fall into the crushing barrel 14. The electric heating wire 17 heats the crushing barrel 14 to dry the coal blocks and prevent them from sticking together after being crushed. The coal blocks crushed by the crushing rod 16 fall into the grinding barrel 13 through the filter plate 18. The filter plate 18 can prevent larger coal blocks from directly entering the grinding barrel 13 and affecting the grinding effect. At this time, the grinding barrel 13, grinding balls 5 and connecting rod 6 and other components operate in accordance with the working method described above to efficiently grind the coal blocks and finally produce fine coal powder.

[0026] Furthermore, to facilitate the collection of the ground coal powder, such as... Figure 1 , Figure 2 and Figure 3 As shown, a collection box 19 is slidably connected inside the bottom box 1, and a handle 20 is fixedly connected to one side of the collection box 19.

[0027] When the grinding mechanism for coal powder production is in use, the ground coal powder will fall into the collection box 19 inside the bottom box 1 through the outlet at the bottom of the grinding barrel 13. The user can easily slide the collection box 19 out of the bottom box 1 by pulling the handle 20, so as to conveniently take out the ground coal powder. This design not only simplifies the coal powder collection process, but also improves the convenience of operation, making the entire coal powder production process more efficient and smooth.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
