Description

Technical Field

[0001] This utility model relates to the field of diamond micron powder processing technology, and in particular to an anti-clogging device for a diamond micron powder airflow pulverizer. Background Technology

[0002] The origins of air jet mills can be traced back to the early 20th century. At that time, with the increasing demand for fine powders in industrial production, traditional pulverizing equipment such as ball mills and Razor mills gradually revealed their limitations when pulverizing materials with high hardness and extremely fine particle size requirements. For example, in the pharmaceutical industry, the fineness requirements for drug powders are very high, and traditional pulverizing equipment is difficult to achieve the ideal pulverizing effect. Therefore, the application of air jet mills has become increasingly widespread.

[0003] In the process of diamond micron powder processing, air jet mills are usually used to ensure the fineness of the powder. Air jet mills are equipped with material conveying devices, and screw conveyors are usually used to transport the material from the feed hopper into the screw conveyor and then into the mill. However, in the traditional air jet mill, the material is poured directly into the feed hopper, and the accumulated material can easily cause blockage. Therefore, this invention proposes an anti-blocking device for diamond micron powder air jet mills to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-clogging device for diamond micron airflow pulverizers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A clogging prevention device for a diamond micron airflow pulverizer includes a pulverizer body. A conveying pipe is fixedly connected to the side wall of the pulverizer body and communicates with the pulverizer body. A feed hopper is fixedly connected to the upper end of the conveying pipe and communicates with the conveying pipe. A fixed plate is fixedly connected to the upper end of the feed hopper. A stirring mechanism for stirring the material in the feed hopper is provided at the lower end of the fixed plate. The stirring mechanism includes a stirring rod rotatably connected to the lower end of the fixed plate. Multiple sets of equally spaced stirring blades are fixedly sleeved on the side wall of the stirring rod. A groove is provided on the fixed plate, and an impact mechanism for impacting the feed hopper is provided in the upper groove.

[0007] Preferably, a second motor is fixedly connected to the upper end of the fixing plate, and the output shaft of the second motor is fixedly connected to the upper end of the stirring rod.

[0008] Preferably, the impact mechanism includes a slider slidably connected in a groove, a movable plate fixedly connected to the upper end of the slider, an L-shaped rod fixedly connected to the side wall of the movable plate, and an impact head fixedly connected to the end of the L-shaped rod away from the movable plate.

[0009] Preferably, the sidewall of the slider and the inner wall of the groove are elastically connected by a spring.

[0010] Preferably, an incomplete gear is fixedly sleeved on the output shaft of the second motor, and a rack that meshes with the incomplete gear is fixedly connected to one side wall of the movable plate.

[0011] Preferably, a spiral blade is rotatably connected inside the conveying pipe, and a first motor is fixedly connected to the end of the conveying pipe, with the output shaft of the first motor fixedly connected to the end of the spiral blade.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By setting up a stirring mechanism, the material is poured into the feeding hopper. During feeding, the output shaft of the second motor is driven to rotate, which drives the stirring rod to rotate, thereby driving the stirring blades to rotate, so as to stir the material in the feeding hopper. This can prevent the material from accumulating in the feeding hopper and causing blockage, and greatly improve the feeding effect.

[0014] 2. By setting up an impact mechanism, during the rotation of the output shaft of the second motor, the incomplete gear is driven to rotate. When the incomplete gear meshes with the rack, it pushes the rack to move, causing the slider and moving plate to move. The compression spring is compressed, thereby driving the L-shaped rod and the impact head to move away from the feed hopper. When the incomplete gear and the rack are not meshed, under the action of the spring, the slider and moving plate are reset, driving the L-shaped rod and the impact head to reset, impacting the feed hopper, thereby vibrating the feed hopper and the material, which can greatly improve the anti-clogging effect while increasing efficiency.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

The feed hopper 3 is connected to the conveying pipe 2, and a fixing plate 10 is fixedly connected to the upper end of the feed hopper 3.

[0023] Furthermore, the lower end of the fixed plate 10 is provided with a stirring mechanism for stirring the material in the feed hopper 3. The stirring mechanism includes a stirring rod 7 rotatably connected to the lower end of the fixed plate 10. Multiple sets of equally spaced stirring blades 6 are fixedly sleeved on the side wall of the stirring rod 7. The upper end of the fixed plate 10 is fixedly connected with a second motor 13, and the end of the output shaft of the second motor 13 is fixedly connected to the upper end of the stirring rod 7.

[0024] Furthermore, a groove 14 is provided on the fixed plate 10, and an impact mechanism for impacting the feed hopper 3 is provided in the upper groove 14. The impact mechanism includes a slider 15 slidably connected in the groove 14. A movable plate 9 is fixedly connected to the upper end of the slider 15. An L-shaped rod 8 is fixedly connected to the side wall of the movable plate 9. An impact head 16 is fixedly connected to the end of the L-shaped rod 8 away from the movable plate 9. It should be noted that the impact head 16 is made of rubber material, which can protect the surface of the feed hopper 3 and avoid damage caused by impact. The side wall of the slider 15 and the inner wall of the groove 14 are elastically connected by a spring 11.

[0025] Furthermore, an incomplete gear 12 is fixedly sleeved on the output shaft of the second motor 13, and a rack 17 that meshes with the incomplete gear 12 is fixedly connected to one side wall of the moving plate 9.

[0027] In use, this invention drives the output shaft of the first motor 4 to rotate during feeding, which in turn drives the spiral blades 5 to rotate, and then pours the material into the feeding hopper 3. During feeding, the output shaft of the second motor 13 is also driven to rotate, which in turn drives the stirring rod 7 to rotate, thereby driving the stirring blades 6 to rotate, thus stirring the material in the feeding hopper 3 and preventing the material from accumulating in the feeding hopper 3 and causing blockage. During the rotation of the output shaft of the second motor 13, the incomplete gear 12 is driven to rotate. When the incomplete gear 12 meshes with the rack 17, it pushes the rack 17 to move, causing the slider 15 and the moving plate 9 to move, compressing the compression spring 11, thereby driving the L-shaped rod 8 and the impact head 16 to move away from the feeding hopper 3. When the incomplete gear 12 and the rack 17 are not meshed, under the action of the spring 11, the slider 15 and the moving plate 9 are reset, driving the L-shaped rod 8 and the impact head 16 to reset, impacting the feeding hopper 3, thereby vibrating the feeding hopper 3 and the material, which can greatly improve the anti-blocking effect while increasing efficiency.
