Description

Technical Field

[0001] The invention belongs to the field of pulverizing equipment, and in particular relates to a needle-type double-rotation high-efficiency pulverizing mechanism. Background Art

[0002] At present, in the pharmaceutical, chemical, food, new materials and other industries, material crushing is widely used as a supporting process. The existing material crushing equipment uses the gap between the high-speed rotating moving needle and the fixed needle to repeatedly hit and collide the material, and at the same time, the material is thrown out of the turntable under the action of centrifugal force to realize the crushing process. Such a single rotor structure has obvious defects under the increasingly sophisticated industrial needs. Because the rotation speed of the single-disc rotor disk is limited, the linear speed of the rotor is not high, resulting in the collision speed between the material particles and the impact needle is not very high, affecting the crushing fineness of the material, and the centrifugal force generated by the single turntable cannot keep the material in the crushing area for a long time. Some particles are thrown out of the crushing area before being completely crushed, resulting in low crushing uniformity. For industries such as medicine and brittle new materials that have high requirements for material fineness, the existing crushing equipment cannot meet them well. Summary of the invention

[0003] In view of the above, the present invention provides a needle-type double-rotation high-efficiency crushing mechanism. Through innovative design, the two turntables rotate synchronously in opposite directions, greatly improving the relative speed of the turntables, thereby making the particle size of the crushed material smaller, and through central feeding, filling can be done without stopping the machine, and the crushing effect is better, thereby improving the overall production efficiency. The specific technical solution is as follows.

[0004] A needle-type double-rotation high-efficiency crushing mechanism comprises a shell, wherein the shell contains a crushing chamber, and is characterized in that it also comprises a non-feeding drive module and a feeding drive module, which are relatively arranged on two sides of the shell through supporting components, a first turntable is arranged at one end of the non-feeding drive module located in the crushing chamber, and a second turntable is arranged at one end of the feeding drive module located in the crushing chamber, a plurality of strikers are arranged on the first turntable and the second turntable, and the strikers on the two turntables are relatively staggered, the non-feeding drive module and the feeding drive module can drive the first turntable and the second turntable to rotate synchronously in opposite directions, the feeding drive module comprises a feeding drive shaft, the feeding drive shaft is a hollow structure, the hollow structure is a feeding channel, a feeding port is opened in the center of the second turntable, one end of the feeding drive shaft is connected to the feeding port of the second turntable, so that the feeding channel is connected to the feeding port.

[0005] Furthermore, the first and second turntables are provided with multiple circles of needle tracks, the needle tracks on the second turntable are staggered with the needle tracks on the first turntable, the needle tracks are concentric circular grooves evenly arranged on the turntables, and the strikers are evenly arranged on each circle of needle tracks.

[0006] Furthermore, the strikers on the first rotating disk and the second rotating disk are of equal length and are inserted into each other's roots.

[0007] Furthermore, the feed drive module also includes a second drive pulley, a second flange and a second bearing seat. The second drive pulley is arranged on the outer wall of one end of the feed drive shaft outside the shell for connecting the belt.

[0008] Furthermore, the feed drive shaft is connected to the second turntable via a second flange, and a keyway is provided on the inner wall of the second flange, which matches with a key provided on the outer wall of one end of the feed drive shaft.

[0009] Furthermore, the feed drive shaft is fixed to a support component on one side of the shell through a second bearing seat. The feed drive shaft passes through the center of the support component, and a skeleton oil seal is provided at the connection with the support component.

[0010] Furthermore, the non-feed drive module includes a non-feed drive shaft, a first flange, a first drive pulley and a first bearing seat. One end of the non-feed drive shaft inside the shell is connected to the first turntable, and the first drive pulley is arranged on the outer wall of one end of the non-feed drive shaft outside the shell for connecting the belt.

At the same time, the driving shaft on one side is designed as a hollow structure, which is directly connected to the center of the turntable as a feed channel, so that the material entering from the center stays in the double turntable for a long time, and the particles are diffused from the center to the periphery under the action of centrifugal force, and the grinding uniformity is better and the quality is higher. In addition, outside the pulverizing mechanism, filling can be directly carried out without stopping the machine through pneumatic feeding and other methods, which greatly improves the efficiency of the entire pulverizing process, and the output can be increased to more than 50%.

[0020] See also Figure 1-Figure 2 The needle-type double-rotation high-efficiency pulverizing mechanism in this embodiment includes a housing 1, a non-feeding drive module 2 and a feeding drive module 3. The housing 1 contains a pulverizing chamber 11. The non-feeding drive module 2 and the feeding drive module 3 are arranged on both sides of the housing 1 via a supporting component 4. The feeding drive module 2 is provided with a first rotating disk 21 at one end of the pulverizing chamber 11, and the feeding drive module 3 is provided with a second rotating disk 31 at one end of the pulverizing chamber 11. The non-feeding drive module 2 and the feeding drive module 3 can drive the first rotating disk 21 and the second rotating disk 31 to rotate synchronously in opposite directions. The material to be pulverized enters between the two rotating disks from one end of the feeding drive module 3, is pulverized at high speed, and is thrown out of the rotating disk into the pulverizing chamber, and is discharged from the discharge port 12 below the pulverizing chamber and collected.

[0021] More specifically, the first turntable 21 and the second turntable 31 have multiple needle tracks, and the needle tracks are concentric circular grooves evenly arranged on the turntables. The needle track on the first turntable 21 is the first needle track 212, and the needle track on the second turntable 31 is the second needle track 312. The second needle track 312 is staggered with the first needle track 212, and a plurality of strikers are arranged on the second needle track 312 and the first needle track 212, such as Figure 4 , the striker on the first rotating disk 21 is the first striker 211, such as Figure 6 The striker on the second rotating disk 31 is the second striker 311. The first striker 211 and the second striker 311 are respectively and evenly arranged on each circle of the first needle track 212 and the second needle track 312. The first striker 211 and the second striker 311 are equal in length and inserted into each other's root. In a specific embodiment, the needle track can be set to 5-7 circles, and the striker is a cylindrical rod. The actual size can be selected according to the crushing requirements of the grinding material, which is also included in the claims of this application.

[0022] More specifically, refer to Figure 5 and Figure 7The feed drive module 3 includes a feed drive shaft 32, a second drive pulley 33, a second flange 34 and a second bearing seat 35.

One end of the feed drive shaft 32 is connected to the feed port 313 of the second turntable 31, so that the feed channel 321 is connected to the feed port 313. In this way, the material to be crushed is directly fed into the space between the second turntable 31 and the first turntable 21 through the feed channel 321 by the external feeding mechanism, so that the material can be filled without stopping the machine. At the same time, due to the centrifugal force, the material entering the space between the second turntable 31 and the first turntable 21 from the center stays longer between the two rotors, and can be more fully crushed, thereby obtaining a powder with higher particle fineness. It should be noted that the external feeding mechanism preferably uses pneumatic feeding, that is, through the mixing of the material and the gas, the material is pressed into the turntable from the open end of the feed channel 321 and crushed. Or it can be an existing feeding trough or feeding manipulator structure that matches the feeding channel 321, but the feeding mechanism is required not to contact the side wall of the feeding channel 321 and the feeding drive shaft 32. Here, the external feeding mechanism can use existing mature technology, so it is not described in detail.

[0023] In addition, the second driving pulley 33 is arranged on the outer wall of one end of the feed drive shaft 32 outside the housing 1, for connecting the belt, and then the belt connects the feed drive shaft 32 and the external motor, thereby driving the feed drive shaft 32 and the second turntable 31 to rotate. The feed drive shaft 32 is connected to the second turntable 31 through the second flange 34, and a keyway 341 is arranged on the inner wall of the second flange 34, which matches the key arranged on the outer wall of one end of the feed drive shaft 32, and fixes the feed drive shaft 32 to the second turntable 31, and the second flange 34 is fixed to the outer wall of the second turntable 31 by screws. The feed drive shaft 32 is fixed to the support component on one side of the housing 1 through the second bearing seat 35, and the feed drive shaft 32 passes through the center of the support component 4, and a skeleton oil seal is arranged at the connection with the support component 4 to prevent the particles in the crushing chamber 11 from overflowing from the connection.
