Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a raw material grinding equipment for the production of piperazine compounds. Background Technology

[0002] In the production of piperazine compounds (such as piperazine, methylpiperazine, ethylenediaminepiperazine, etc.), the grinding of raw materials or intermediates is a critical step affecting reaction efficiency and product quality. Because piperazine compounds typically involve high-purity, flammable, explosive, or corrosive raw materials (such as ethylenediamine, chlorinated hydrocarbons, ammonia, etc.), grinding equipment must meet special requirements for safety, explosion-proof properties, and corrosion resistance.

[0003] After grinding for a period of time, existing grinding equipment will have some grinding debris adhering to the surface of the grinding wheel. Continued use will affect the grinding effect, so the grinding wheel needs to be cleaned. Existing technology usually requires disassembling the outer shell to clean it, which is very inconvenient and affects the grinding efficiency. In addition, existing grinding equipment has difficulty in ensuring uniform feeding during the feeding process. The material usually only falls to one position of the grinding equipment, which further affects the grinding effect.

[0004] Therefore, we propose a raw material grinding device for the production of piperazine compounds to solve the problems mentioned above. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figure 1-5 This utility model provides an embodiment of a raw material grinding device for the production of piperazine compounds, comprising a base box 9, a transmission cylinder 2 and a hopper 1 arranged above the base box 9, a rotating mechanism 3 arranged on the base box 9, the rotating mechanism 3 including a motor 31, the rotating mechanism 3 also including a rotating shaft 34, the motor 31 being used to drive the rotating shaft 34 to rotate; a vibration mechanism 4 arranged on the rotating shaft 34, the vibration mechanism 4 including a slide cylinder 41, the slide cylinder 41 being keyed to the rotating shaft 34, a movable grinding wheel 5 connected to the slide cylinder 41, a fixed grinding wheel 6 connected to the inner wall of the transmission cylinder 2, the vibration mechanism 4 being used to drive the vibration of the fixed grinding wheel 6 and the movable grinding wheel 5, a movable groove 7 being opened on the surface of the transmission cylinder 2, the fixed grinding wheel 6 being slidably connected in the movable groove 7.

[0022] The rotating mechanism 3 can drive the moving grinding wheel 5 to rotate, thereby grinding the piperazine compound raw material that enters between the fixed grinding wheel 6 and the moving grinding wheel 5. At the same time, the vibration mechanism 4, driven by the rotating mechanism 3, can drive the fixed grinding wheel 6 and the moving grinding wheel 5 to vibrate, thereby shaking off the debris adhering to the surface of the fixed grinding wheel 6 and the moving grinding wheel 5, thus improving the grinding effect.

[0023] Please see Figure 3 , Figure 4 The rotating mechanism 3 also includes a driving bevel gear 32, which is connected to the output end of the motor 31. The motor 31 is installed in the base box 9. The rotating shaft 34 extends into the base box 9 and is connected to a driven bevel gear 33. The driving bevel gear 32 and the driven bevel gear 33 mesh.

[0024] The operating principle of the rotating mechanism 3 is as follows: first, the motor 31 is started, and the motor 31 drives the active bevel gear 32 connected to it to rotate. The active bevel gear 32 further drives the driven bevel gear 33 that meshes with it to rotate. The rotating shaft 34 connected to the driven bevel gear 33 rotates synchronously, thereby ultimately driving the moving grinding wheel 5.

[0025] Please see Figure 3 The vibration mechanism 4 also includes a spring 48, which is sleeved on the rotating shaft 34 and connected to the slide cylinder 41. A fixing ring 44 is fixedly connected to the bottom box 9. The surface of the fixing ring 44 has multiple grooves. An L-shaped rod 42 is connected to the outer wall of the slide cylinder 41. A rotating wheel 43 is rotatably connected to one end of the L-shaped rod 42 near the fixing ring 44. The rotating wheel 43 is slidably connected to the fixing ring 44.

[0026] Please see Figure 3 , Figure 4 Two symmetrically arranged locking keys 47 are fixedly connected to the rotating shaft 34. The locking keys 47 are slidably connected to the slide cylinder 41. Multiple connecting rods 45 arranged in a ring are fixedly connected to the outer wall of the slide cylinder 41. A pulley 46 is rotatably connected to the connecting rod 45. The pulley 46 is in contact with the surface of the fixed grinding wheel 6.

[0027] The working principle of the vibration mechanism 4 is as follows: as the rotating shaft 34 rotates, the slide cylinder 41 connected to the key on the rotating shaft 34 rotates synchronously, and the L-shaped rod 42 connected to the slide cylinder 41 rotates synchronously. The rotating wheel 43 connected to the L-shaped rod 42 moves on the fixed ring 44. Since the surface of the fixed ring 44 is uneven, it drives the rotating wheel 43, the L-shaped rod 42, the slide cylinder 41 and the moving grinding wheel 5 to move up and down synchronously. At the same time, the connecting rod 45 moves synchronously with the up and down movement of the slide cylinder 41. The pulley 46 on the connecting rod 45 pushes the fixed grinding wheel 6 that is slidably connected to the transmission cylinder 2, thereby driving the fixed grinding wheel 6 to move up and down. Finally, the debris adhering to the fixed grinding wheel 6 and the moving grinding wheel 5 is shaken off, thereby improving the grinding effect.

[0028] Please see Figure 2 The hopper 1 is provided with a material distribution mechanism 8, which includes a material distribution cone 81. The material distribution cone 81 is disposed inside the hopper 1. An arc-shaped ring 83 is connected to the inner wall of the hopper 1. A gap is provided between the arc-shaped ring 83 and the material distribution cone 81, and multiple fixing blocks 82 are fixedly connected between the arc-shaped ring 83 and the material distribution cone 81.

[0029] The material distribution mechanism 8 can evenly disperse the falling material between the fixed grinding wheel 6 and the moving grinding wheel 5. During feeding, the material is sprinkled from above the material distribution cone 81. The material is evenly separated by the diversion of the material distribution cone 81. The material finally falls through the gap between the material distribution cone 81 and the arc ring 83.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
