Description

Technical Field

[0001] This utility model belongs to the field of abrasive production and processing, specifically, it relates to a crusher structure and an airflow mill. Background Technology

[0002] An air jet mill is a device that uses high-speed airflow to pulverize material particles by causing them to impact, collide, or rub against the mill wall. It features fine particle size, uniform particle size distribution, and no mechanical wear.

[0003] The traditional air jet mill has an empty pulverizer structure. This causes the material to fall and accumulate at the bottom due to its large size when the air jet conveys it upwards. It can then be re-mixed with the high-speed air jet for crushing. Although this process can achieve air jet crushing of the material, its efficiency is low.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0029] like Figure 1 and Figure 2 As shown, a crusher structure includes: a crushing chamber 20, which is a hollow cylindrical shape; an air pipe 21 is fixedly connected to the side wall of the crushing chamber 20, the air pipe 21 is cylindrical and can extend into the cavity of the crushing chamber 20; an air compressor is installed at the outer end of each air pipe 21; a feed pipe 22 is fixedly connected to the bottom of the crushing chamber 20, the feed pipe 22 is cylindrical and the top end of the feed pipe 22 can extend from the bottom of the crushing chamber 20 into the cavity of the crushing chamber 20; the air compressor is electrically connected to a corresponding power supply; and the bottom of the feed pipe 22 is connected to a conveying pipe. This is existing technology and will not be described in detail here.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the auxiliary structure is set inside the crushing chamber 20 to guide the material. The auxiliary structure includes: an air duct 32, a material guide plate 33, and a flow guide block 34. The air duct 32 is detachably installed inside the crushing chamber 20, and the material guide plate 33 is also detachably connected inside the crushing chamber 20. The flow guide block 34 is fixedly connected to the wall of the material guide plate 33. Multiple air ducts 32 and material guide plates 33 are arranged in a ring array inside the crushing chamber 20.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the air intake plate 32 is fan-shaped, with its pointed tip curving upwards. The material feed plate 33 is also fan-shaped, with its pointed tip folding downwards. Guide blocks 34 are fixedly connected to the pointed tips of each material feed plate 33. The air intake plates 32 are located above each air pipe 21, and the material feed plates 33 are located between each adjacent air pipe 21. The outer arc surfaces of multiple air intake plates 32 and material feed plates 33 can form a complete circle. The guide blocks 34 are isosceles triangular blocks, with their planes facing the center of the crushing chamber 20. The wavy surface and auxiliary structure also include a bottom ring 30, a docking block 31 and a locking groove 35. The bottom ring 30 is fixedly connected to the cavity of the crushing chamber 20, the docking block 31 is fixedly connected to the top of the bottom ring 30, and the locking groove 35 is opened through the wall of the feed plate 33 and the air plate 32. The bottom ring 30 is circular, the docking block 31 is rectangular, the locking groove 35 can be adapted to the size of the docking block 31, and the docking block 31 can be inserted into the locking groove 35. The number of docking blocks 31 is the same as all the air plates 32 and feed plates 33 at the top of the bottom ring 30.

[0032] In practical use, first turn on the power. When the power is on, the air compressor will deliver high-pressure air into the crushing chamber 20 through the air pipe 21. The high-pressure air introduced into the crushing chamber 20 through the air pipe 21 will move upward when it converges at the center of the crushing chamber 20. At this time, the conveying pipe is opened, and the material discharged from the conveying pipe will be introduced into the crushing chamber 20 upward through the feed pipe 22. The material entering the crushing chamber 20 will move upward due to the high-speed airflow and will then come into contact with the screen above the crushing chamber 20. The material that is too large will slide to the side and then fall onto the guide. At the top of the air plate 32 and the feed plate 33, when the material falls to the top of the air plate 32, it will slide towards both sides of the air plate 32 due to the inclined surface of the top of the air plate 32. The sliding material will fall onto the inclined surfaces of the feed plates 33 on both sides, and then the material will slide towards both sides along the inclined surfaces of the feed plates 33. At this time, after the material slides down the wall of the feed plate 33, it will directly contact the high-speed airflow blown out by the air pipe 21 and be ground directly with the high-speed airflow. The high-speed airflow will pass through all the guide blocks 34 at the confluence center in the crushing chamber 20. The wavy surface of the guide block 34 can guide the airflow.

[0033] In summary, by setting up an auxiliary structure to guide the material to mix directly with the high-speed airflow, the grinding efficiency of the material is accelerated, thereby effectively reducing the grinding time required. This makes the solution more efficient than existing technologies.

[0034] like Figure 4As shown, the top of the air intake plate 32 is provided with a fixing structure, which includes a cover ring 36, a post 37 and a bolt 38. The cover ring 36 is detachably connected to the top of the air intake plate 32 and the feed plate 33. The post 37 is fixedly connected to the bottom of the cover ring 36. The bolt 38 is threadedly connected to the top of the cover ring 36. The cover ring 36 is a circular ring with the same size as the bottom ring 30. The post 37 is cylindrical. The top of each docking block 31 is provided with a circular groove adapted to the insertion of the post 37. The number of posts 37 is the same as the number of docking blocks 31. The walls of the air intake plate 32, the feed plate 33 and the bottom ring 30 are provided with threaded grooves adapted to the size of the bolt 38. The bolt 38 can be threadedly connected to both the cover ring 36 and the bottom ring 30 at the same time.

[0035] In practical use, when it is necessary to replace the individual air venting plate 32 and material venting plate 33, remove the bolt 38 from the top of the cover ring 36, and then the cover ring 36 will be unlocked. At this time, remove the cover ring 36, and then the air venting plate 32 and material venting plate 33 to be replaced can be removed. Then, the new air venting plate 32 and material venting plate 33 are snapped into the corresponding mating block 31 wall surface through the locking groove 35 opened on their wall surface. Then, the cover ring 36 is placed on the top of the air venting plate 32 and material venting plate 33 and the bolt 38 is tightened.

[0036] In summary, by setting up a fixed structure with detachable feed plate 33 and air vent plate 32, individual feed plates 33 and air vent plate 32 can be replaced directly without replacing the entire device, thereby effectively reducing the cost of device maintenance.

[0037] An airflow mill, not shown in the figure, includes a housing and a screener, the screener being fixedly installed on the top of the housing, and also includes all of the above-mentioned crusher structures, the crushing chamber 20 being fixedly connected to the cavity of the housing, the material conveyed in the crushing chamber 20 being screened by the screener.

[0038] By setting up a crusher structure, the efficiency of material grinding can be effectively improved.

[0039] Working principle: First, the power is turned on. When the power is on, the air compressor delivers high-pressure air into the crushing chamber 20 through air pipe 21. The high-pressure air introduced into the crushing chamber 20 through air pipe 21 converges at the center of the crushing chamber 20 and moves upward. At this time, the conveying pipe is opened, and the material discharged from the conveying pipe is introduced into the crushing chamber 20 upward through the feed pipe 22. The material entering the crushing chamber 20 moves upward due to the high-speed airflow and then comes into contact with the screen above the crushing chamber 20. Materials that are too large will slide to the side and fall onto the top of the air intake plate 32 and the feed plate 33. When the material falls onto the top of the air intake plate 32, it will slide to both sides of the air intake plate 32 due to the slope of the top of the air intake plate 32. The sliding material will fall onto the slope of the feed plate 33 on both sides, and then slide to both sides along the slope of the feed plate 33. At this time, after the material slides off the wall of the feed plate 33, it will directly come into contact with the high-speed airflow blown out by the air pipe 21 and be ground directly with the high-speed airflow.
