Description

Technical Field

[0001] This invention relates to the field of pulverizer technology, specifically to a vortex pulverizer based on fine pulverization. Background Technology

[0002] For the crushing of metals or non-metals, impact or shearing methods are generally used. However, these methods result in large, irregularly shaped particles, low production efficiency, high costs, and require special protective measures when processing some materials. For example, the manufacture of magnesium powder requires complex flame-retardant measures, and the particle size can only reach about 100 mesh.

[0003] Traditional equipment relies on single impact or extrusion, resulting in a wide particle size distribution after crushing, requiring external grading equipment for recycling, which is inefficient. The high-speed rotating crushing parts rub intensely against the material, generating a large amount of heat, which can alter the properties or cause adhesion of heat-sensitive materials (such as resins and traditional Chinese medicines). For fibrous or highly tough materials, traditional equipment is prone to entanglement and clogging of the cutter head and screen, affecting continuous operation. Furthermore, the need to achieve a finer crushing fineness requires extended crushing time or increased rotation speed, leading to a significant increase in unit energy consumption. Moreover, there is no supporting packaging equipment, and even if some packaging equipment is installed, it cannot be used for packaging operations.

[0004] Therefore, developing a vortex pulverizer that can achieve fine and uniform material pulverization, effectively control pulverization temperature, avoid clogging, reduce energy consumption, and automatically dispense materials has significant engineering application value.

Crushing relies on the self-collision of particles in the vortex. The material is self-crushed at high frequency and low energy in the vortex field, resulting in high energy utilization and effective crushing of materials to the target mesh size. Compared with traditional crushing devices, it can effectively improve crushing efficiency.

This significantly saves time spent on specification switching, improves production continuity, and the material conveying adopts a fully enclosed structure, effectively preventing materials from being contaminated by the outside world and ensuring product quality.

[0050] The working principle of the above embodiments is as follows:

[0051] In use, the material to be crushed is first poured into the storage hopper 316, and then falls into the crushing chamber 302 by gravity. The servo motor 304 then drives the limit sleeve 307 and the crushing disc 306 to rotate, engaging with the paddles 315 mounted on the cover plate 313 to impact, shear, and crush the material. As the crushing disc 306 rotates at high speed, a vortex is formed inside the crushing chamber 302 under the guidance of the paddles 315. This vortex participates in the crushing operation, further improving the crushing effect, and forming a vortex inside the crushing chamber 302. Negative pressure effectively prevents dust leakage. After being crushed to the target mesh size, the powder falls onto the guide plate 310 after being filtered by the screen 311 and then into the outer shell 211 for sieving. When it is necessary to crush materials to different mesh sizes, the cover plate 313 can be deflected and opened around the hinge 312 by rotating the locking block 319 to disengage from the limiting block 318. At this time, the screen 311 can be taken out of the crushing chamber 302, and a new screen 311 can be inserted into the crushing chamber 302 and replaced by limiting it with the positioning ring.

[0052] The crushed material falls into the outer shell 211. At this time, the first drive motor 202 rotates, driving the rotating disk 203 and the lever 204 to rotate. It also drives the sliding rod 207 and the first sliding sleeve 206 to move back and forth through the guide ring 205. This further drives the outer shell 211 and the first screen plate 212 and the second screen plate 213 installed inside to move back and forth and perform a grading process on the material. The graded material enters the next process through the first discharge port 214 and the second discharge port 215.

[0053] After the material is graded, the powdered material is transported through the first conveying pipe 403 and the connecting hose 404 to the second conveying pipe 405 via a blower installed in the transfer chamber 406. Simultaneously, the straight packaging bag on the packaging cylinder 429 passes through the limiting rotating rod 430, is shaped by the bushing 426, and enters the gap between the bushing 426 and the second conveying pipe 405. At this point, the second drive motor 435 is activated, driving the motor wheel 433 to rotate, which in turn drives the belt 436 to push the shaped packaging bag downwards. Simultaneously, the second cylinder 437 is activated to push the back seal 438 to heat-melt and seal the packaging bag joint. As the packaging bag continues to move downwards to between the front bottom seal 421 and the rear bottom seal 424, the first cylinder 410 is activated, causing it to retract. This retracts the first connecting plate 411, the second mounting piece 412, and the sliding rod 418 towards the first cylinder 410, and pushes the movable rod 413 to the side of the first connecting plate 411. The moving part 415 deflects, which in turn pulls the third mounting part 417, the second connecting plate 420 and the front bottom seal 421 towards the rear bottom seal 424 via the second moving rod 416. At the same time, the first cylinder 410 retracts, which drives the sliding rod 418, the fourth connecting plate 425, the third connecting plate 423 and the rear bottom seal 424 towards the first cylinder 410. The front bottom seal 421 and the rear bottom seal 424 move towards each other, and the two heat-melt and bond the packaging bag and cut the bonded part in the middle. At this time, the material falls into the packaging bag. The first cylinder 410 pushes the front bottom seal 421 and the rear bottom seal 424 away. When enough material powder enters the packaging bag, the first cylinder 410 retracts to close and cut the bag opening. The packaging operation can be carried out by repeating this cycle. According to different fineness, the automatic packaging mechanism 4 and the second packaging component 5 can be used to package separately. After packaging, the packaging is transferred to the stacking area by the conveyor belt.

[0054] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
