Traditional Chinese medicine superfine pulverizer

Abstract

This invention relates to the field of traditional Chinese medicine pulverization technology, and more particularly to an ultrafine pulverizer for traditional Chinese medicine. It includes a frame equipped with a cyclone separator and a pulse dust collector; electrically controlled telescopic rods, all circumferentially arranged within the pulverizer; and a cleaning toothed ring, which is slidably and sealingly connected within the frame. The telescopic ends of the electrically controlled telescopic rods are fixedly connected to the cleaning toothed ring, which is used to clean the interior of the pulverizer. This invention uses the cleaning toothed ring to push out the traditional Chinese medicine particles between the crushing teeth and the pulverizing roller, clearing clogged particles from the pulverizer without disassembly. The cyclone separator then extracts these pushed-out particles, thus preventing clogging between the crushing teeth and the pulverizing roller. This also avoids frequent disassembly and maintenance after pulverizer clogging, which could lead to seal failure and dust leakage during pulverization, resulting in waste of traditional Chinese medicine powder.

Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine pulverization technology, and in particular to an ultrafine pulverizer for traditional Chinese medicinal materials. Background Technology

[0002] The Chinese herbal medicine ultrafine pulverizer is a device specifically designed to pulverize Chinese herbal medicines to micron or even nanometer particle size. Through ultrafine pulverization technology, it can significantly improve the extraction rate and bioavailability of the active ingredients in the herbs, as well as improve their solubility and absorption. It can pulverize a variety of herbs, including roots, stems, fruits, and minerals.

[0003] Existing ultrafine pulverizers typically use high-speed rotating hammer blades to impact the medicinal materials when pulverizing them, causing them to be initially pulverized. The medicinal materials collide with each other or with the blades. Afterward, the initially pulverized medicinal materials are further pulverized through a grinding operation between the pulverizing roller and the toothed ring, and the pulverized medicinal materials are collected by the negative pressure suction of the separator.

[0004] However, during long-term use, existing crushing rollers and toothed rings are prone to accumulating Chinese herbal powder between them, leading to blockages. This results in a large accumulation of Chinese herbal powder in the crushing chamber, reducing the space within the chamber and consequently decreasing the crushing effect of the rollers and toothed rings on the herbs. Consequently, the crushing efficiency and quality of the herbs are affected. As a result, operators need to disassemble the crusher and clean its interior. Over time, frequent disassembly and maintenance of the crusher can lead to seal failure, causing dust to leak out during the crushing process and impacting the external environment.

Detailed Implementation

[0042] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below.

[0043] During long-term use, the existing grinding roller and toothed ring are prone to accumulating Chinese herbal medicine powder, which can cause blockage. This leads to a large accumulation of Chinese herbal medicine powder in the grinding chamber, reducing the usable space and affecting the grinding efficiency and quality of Chinese herbal medicine. As a result, operators need to frequently disassemble the grinder and clean the inside. However, frequent disassembly and maintenance not only increase the workload but may also cause the grinder's seal to fail, resulting in dust leakage during the grinding process and wasting Chinese herbal medicine powder.

[0044] Reference Figures 1-8The following is an embodiment of the present invention: a Chinese herbal medicine ultrafine pulverizer, including a frame 1, the internal structure of which is not shown in the figure. Casters are installed at the bottom of the frame 1 to facilitate changing the placement of the device. A control panel (not shown in the figure) is provided on the outside of the frame 1. A cyclone separator 101 and a pulse dust collector 102 are installed on the frame 1. Both the cyclone separator 101 and the pulse dust collector 102 are electrically connected to the control panel. A collection container is connected to the lower side of the cyclone separator 101. The cyclone separator 101 is connected to the pulse dust collector 102. The cyclone separator 101 collects the pulverized Chinese herbal medicine into its interior using negative pressure, and then centrifugal force is used to process the pulverized medicine. Heavier particles (i.e., substandard Chinese medicine particles) and lighter particles (i.e., compliant Chinese medicine particles) are collected separately. Substandard particles move towards the cylinder wall under centrifugal force and can be collected separately or transported to a secondary crushing location through a pipeline. Compliant particles are discharged from the bottom of the cyclone separator 101 and enter the collection container. The pulse dust collector 102 is equipped with filter bags. Dust-laden gas passes through the filter bags, and dust is trapped on the surface of the filter bags. The feeder 2 is set on the frame 1 and has a feed hopper 201 and a conveying pipe 202. The conveying pipe 202 can be equipped with a screw conveyor structure (i.e., auger) or a vibrating conveyor structure. The feeding hopper 201 transports the traditional Chinese medicine to the right side of the conveying pipe 202, maintaining the stability of the flow and reducing the possibility of blockage in the conveying pipe 202. The feeding hopper 201 and the conveying pipe 202 are connected. The pulverizer 3 is located on one side of the conveying pipe 202, and both the conveying pipe 202 and the cyclone separator 101 are connected to the pulverizer 3. The triggering component 4 is located inside the conveying pipe 202 and is used to detect the amount of material accumulated in the conveying pipe 202. There are at least two electrically controlled telescopic rods 501, which are electrically connected to the control panel. All electrically controlled telescopic rods 501 are arranged circumferentially on the pulverizer 3 to clear the toothed ring. 502. The unblocking toothed ring 502 is slidably connected to the frame 1. The telescopic end of the electrically controlled telescopic rod 501 is fixedly connected to the unblocking toothed ring 502. After blockage occurs in the pulverizer 3, the trigger component 4 is triggered and the signal is fed back to the control panel. The control panel controls the telescopic end of the electrically controlled telescopic rod 501 to retract. The telescopic end of the electrically controlled telescopic rod 501 drives the unblocking toothed ring 502 to move upward, pushing out the Chinese medicine particles that are blocked in the pulverizer 3, thus unblocking the pulverizer 3. This ensures its normal operation without disassembling the pulverizer 3, thereby avoiding frequent disassembly and maintenance after blockage, which may lead to seal failure and dust leakage during the Chinese medicine pulverization process, resulting in waste of Chinese medicine powder.

[0045] Furthermore, the pulverizer 3 includes: a pulverizing housing 301, which is bolted to the frame 1, and an electrically controlled telescopic rod 501 is fixedly connected to the pulverizing housing 301; a plurality of crushing teeth 302, which are circumferentially arranged on the inner wall of the pulverizing housing 301, and the crushing teeth 302 increase in size from near the material conveying pipe 202 to far away; and a pulverizing roller 303, which is rotatably disposed inside the pulverizing housing 301, and a clearing tooth ring 502 is in a sealing sliding fit with the plurality of crushing teeth 302 and the pulverizing roller 303. The pulverizing roller 303 is provided with circumferentially evenly distributed grinding teeth. In this embodiment, the lower part of the circumferentially distributed grinding teeth of the pulverizing roller 303 is pointed, so as to facilitate the insertion of the clearing tooth ring 502 from bottom to top into the plurality of teeth. Between the crushing teeth 302 and the crushing roller 303, the lower side of the crushing roller 303 can be directly connected to the output shaft of the motor, or it can be driven to rotate by an external pulley. Regardless of the transmission structure, it can be embedded in the frame 1 and electrically connected to the control panel to drive the crushing roller 303 to rotate at high speed and crush the Chinese medicine. The distribution of the size of the crushing teeth 302 in the above-mentioned manner makes the gap between several crushing teeth 302 and the crushing roller 303 gradually decrease from left to right. The Chinese medicine enters the gap between the left crushing teeth 302 and the crushing roller 303 from the left feeding pipe 202. As the crushing roller 303 rotates, the Chinese medicine gradually rotates to the gap between the right crushing teeth 302 and the crushing roller 303, and the Chinese medicine is crushed layer by layer (the above left and right directions are all based on the principle of mutual respect to ... Figure 4 (For example), there are several hammer blades 304, which are evenly arranged circumferentially on the crushing roller 303. The crushing roller 303 rotates at high speed, driving all the hammer blades 304 to rotate, crushing the Chinese medicine. This causes the Chinese medicine to be initially crushed by the hammer blades 304 when it enters the gap between the crushing teeth 302 and the crushing roller 303, preventing the raw materials of the Chinese medicine from being too large to enter the gap between the crushing teeth 302 and the crushing roller 303. Furthermore, during the rotation of the crushing roller 303, it uses centrifugal force to throw larger Chinese medicine particles to the circumferentially distributed hammer blades 304, thus further crushing the Chinese medicine. The medicinal particles continuously impact the crushing teeth 302 and the hammer blade 304 to enhance the degree of pulverization of the traditional Chinese medicine. The height of the crushing teeth 302 is X, the height of the crushing roller 303 is Y, and the height of the hammer blade 304 is L, where X>Y+L. This increases the roughness of the inner wall of the crushing housing 301. Even if the traditional Chinese medicine is smashed and splashed after contacting the hammer blade 304, it will still splash upwards onto the crushing teeth 302 (in this embodiment, the uppermost side of the crushing teeth 302 can be attached to the upper side wall inside the crushing housing 301), increasing the number of times the traditional Chinese medicine collides with the crushing teeth 302, thereby enhancing the pulverization effect of the traditional Chinese medicine.

[0046] Furthermore, the triggering component 4 includes: a sealing ring 401, which is slidably disposed within the conveying pipe 202 and located on the left side of the connection between the feed hopper 201 and the conveying pipe 202 to prevent the traditional Chinese medicine from entering the left side of the sealing ring 401; an elastic element, which is a compression spring, is fixedly connected between the sealing ring 401 and the conveying pipe 202; and a pressure sensor 402, disposed on the left side of the inner wall of the conveying pipe 202, electrically connected to the control panel, and the pressure sensor 402 is connected to the sealing ring 401. The space between the crushing teeth 302 and the crushing roller 303 is a sealed chamber. After the gap between the crushing teeth 302 and the crushing roller 303 is blocked by accumulated medicinal herbs, the medicinal herbs inside the crushing housing 301 can no longer enter the gap between the crushing teeth 302 and the crushing roller 303. Under the centrifugal force of the rotating crushing roller 303, the medicinal herbs accumulate around the circumference of the crushing roller 303, leading to an increase in the amount of medicinal herbs inside the crushing housing 301 and a greater accumulation of medicinal herbs on the upper side of the crushing roller 303. This results in a gradual accumulation of a large amount of medicinal herbs at the connection point of the conveying pipe 202. The increased resistance to the movement of the Chinese medicine towards the connection point of the conveying pipe 202 slows down the conveying speed of the Chinese medicine within the conveying pipe 202. The sealing ring 401 is compressed by the Chinese medicine, causing the elastic element of the sealing ring 401 to compress. This creates high pressure in the sealed chamber, increasing the pressure on the pressure sensor 402. The pressure sensor 402 sends a command back to the control panel, which then stops the operation of the transmission structure of the crushing roller 303 and the conveying structure within the conveying pipe 202. After the conveying structure inside channel 202 stops operating, the control panel controls the telescopic ends of the two electrically controlled telescopic rods 501 to retract simultaneously. The two electrically controlled telescopic rods 501 drive the unblocking tooth ring 502 to move upward. The unblocking tooth ring 502 passes through the gaps between several crushing teeth 302 and the crushing roller 303, pushing the Chinese medicine particles accumulated in the gaps to the top of the crushing roller 303. Then, the pushed-out Chinese medicine particles are extracted into the interior of the cyclone separator 101 to prevent blockage in the crushing shell 301, thereby improving the crushing efficiency and crushing quality of Chinese medicine.

[0047] Working principle: First, the transmission structure of the cyclone separator 101, pulse dust collector 102, and crushing roller 303, as well as the conveying structure in the conveying pipe 202, are activated via the control panel. Then, the traditional Chinese medicine is conveyed to the crushing shell 301 through the feed hopper 201 and the conveying pipe 202. The crushing roller 303 rotates and engages with all the crushing teeth 302 to crush the traditional Chinese medicine located in the gaps between them. At the same time, the hammer 304 rotates and strikes the traditional Chinese medicine, performing initial crushing. After the traditional Chinese medicine particles accumulate in the gaps between the crushing teeth 302 and the crushing roller 303, causing blockage in the crushing shell 301, the sealing ring 401 slides, causing the pressure sensor 402 to be triggered by pressure. The control panel then closes the transmission structure of the crushing roller 303 and the conveying structure in the conveying pipe 202. The control panel activates two electrically controlled telescopic rods 501, which drive the unblocking toothed ring 502 to move upward (in this embodiment, the crushing roller 303...). The lower part of the grinding teeth distributed in the direction of 03 is pointed. The unblocking tooth ring 502 is inserted between the crushing tooth 302 and the crushing roller 303 through its lower pointed tip. The unblocking tooth ring 502 pushes out the Chinese medicine particles accumulated in the gap between the crushing tooth 302 and the crushing roller 303. The cyclone separator 101 extracts the pushed-out Chinese medicine particles to prevent the gap between the crushing tooth 302 and the crushing roller 303 from becoming blocked, which would affect the crushing efficiency and crushing quality of the Chinese medicine. After unblocking, the control panel controls the two electrically controlled telescopic rods 501 to reset. The telescopic end of the electrically controlled telescopic rods 501 drives the unblocking tooth ring 502 to move and reset. The control panel controls the electrically controlled telescopic rods 501 to close. After stopping the use of this device, the operator closes the transmission structure of the cyclone separator 101, the pulse dust collector 102, the crushing roller 303 and the conveying structure in the conveying pipe 202 through the control panel. Finally, the device is cleaned for the next use.

[0048] In the above embodiments, the lower part of the circumferentially distributed grinding teeth of the crushing roller 303 is a pointed tip, while in the following embodiments, the lower side of the grinding teeth is a flat surface.

[0049] The above content is Example 1. Based on the above, the following is Example 2. Further, it also includes: a flexible toothed ring 6. The flexible toothed ring 6 is disposed at the lower part of the crushing roller 303 to guide the unblocking toothed ring 502 between several crushing teeth 302 and the crushing roller 303. Before the unblocking toothed ring 502 enters the gap between the crushing teeth 302 and the crushing roller 303, the unblocking toothed ring 502 first passes through the flexible toothed ring 6. If the flexible toothed ring 6 cannot fully fit with the unblocking toothed ring 502 due to rotation, the unblocking toothed ring 502 squeezes the flexible toothed ring 6 to rotate, so that the flexible toothed ring 6 drives the crushing roller 303 to rotate, so that the unblocking toothed ring 502 fits with the crushing roller 303.

[0050] In the above scheme, a flexible toothed ring 6 is added to facilitate the insertion of the toothed ring 502 into the gap between the crushing tooth 302 and the crushing roller 303, thereby reducing the friction between the toothed ring 502 and all the crushing teeth 302 and the crushing roller 303.

[0051] Further, the crushing roller 303 is provided with an annular cavity. A moving ring 701 is arranged in the annular cavity of the crushing roller 303. The moving ring 701 is provided with a plurality of bumps. The vertical height that the bumps on the moving ring 701 can move is H, where H > L and X < Y + H, so that the hammer knives 304 can move to the upper surface of the dredging gear ring 502. In this embodiment, there is a gap between the upper side of the crushing teeth 302 and the upper side of the inner wall of the crushing housing 301, but still X > Y + L. After the dredging gear ring 502 moves to contact all the hammer knives 304, the dredging gear ring 502 can drive all the hammer knives 304 to move upward to the upper side of the crushing teeth 302. The hammer knives 304 are fixedly connected to the moving ring 701 through connecting rods. The hammer knives 304 are in extrusion fit with the dredging gear ring 502. A plurality of arc-shaped grooves are arranged in the crushing roller 303. The bumps of the moving ring 701 slide in adjacent arc-shaped grooves. After the dredging gear ring 502 extrudes all the hammer knives 304 to move upward, the hammer knives 304 drive the moving ring 701 to move upward through the connecting rods. The bumps of the moving ring 701 move along adjacent arc-shaped grooves, causing the moving ring 701 to rotate. The moving ring 701 drives the adjacent hammer knives 304 to rotate through the connecting rods, so that the hammer knives 304 rotate during the upward movement. A rotating ring 702 that is sealingly matched with its annular cavity is arranged on the crushing roller 303 to prevent Chinese medicine particles from entering the annular cavity. The connecting rod of the hammer knife 304 is slidably connected to the rotating ring 702. A plurality of elastic members are fixedly connected between the moving ring 701 and the rotating ring 702. The number of elastic members is the same as the number of hammer knives 304. Among them, the elastic member is a compression spring. When the moving ring 701 moves upward, this elastic member is compressed. The rotation direction of the crushing roller 303 is from the direction of the lower end of the arc-shaped groove of the crushing roller 303 to the direction of its upper end, to prevent relative movement between the crushing roller 303 and the moving ring 701 during rotation. A plurality of scraping blocks 801 are arranged on the hammer knives 304. A flexible part is arranged on the lower side of the scraping blocks 801. The number of scraping blocks 801 is the same as the number of hammer knives 304. The hammer knives 304 rotate during the upward movement. The hammer knives 304 drive the adjacent scraping blocks 801 to rotate. The scraping blocks 801 scrape the Chinese medicine particles adhering to the upper side surface of the dredging gear ring 502, so as to prevent the Chinese medicine particles from being compacted by the upper-side Chinese medicine on the dredging gear ring 502. After the dredging gear ring 502 moves downward to reset, the Chinese medicine particles still adhere to the dredging gear ring 502, resulting in a large number of Chinese medicine particles still remaining between the crushing teeth 302 and the crushing roller 303 after cleaning, thereby affecting the cleaning effect of the dredging gear ring 502 on the crushing teeth 302 and the crushing roller 303. An elastic member is fixedly connected between the scraping block 801 and the adjacent hammer knife 304. Among them, the elastic member is a蓄力 elastic telescopic rod. The scraping block 801 is initially limited by the adjacent crushing teeth 302, so that the elastic member of the scraping block 801 is in a compressed and蓄力 state. After all the hammer knives 304 move upward to the upper side of the crushing teeth 302, this elastic member pops out and drives the adjacent scraping block 801 to move, so that all the scraping blocks 801 are circumferentially dispersed. It should be noted that the term "蓄力" in the original text may not be a standard English expression. You may need to further clarify or correct it according to the actual situation. If it is a misspelling and should be something like "蓄力" (a specific technical term in Chinese that needs to be accurately translated), please provide the correct information for a more accurate translation.The increased contact area between the scraper 801 and the upper side of the unclogging toothed ring 502 enhances the cleaning effect of the scraper 801 on the unclogging toothed ring 502, reducing the amount of herbal particles adhering to the unclogging toothed ring 502. After cleaning, the unclogging toothed ring 502 resets, the elastic element of the moving ring 701 rebounds and drives it to reset, and the flexible part on the lower side of the scraper 801 squeezes the adjacent crushing teeth 302, causing the scraper 801 to reset and drive its elastic element to reset. The height of the scraper 801 is less than the height of the adjacent hammer blade 304, and the lower side of the inner wall of the conveying pipe 202 is flush with the upper side of the scraper 801 to ensure that the material contacts the hammer blade 304 after entering the crushing shell 301.

[0052] Working principle: After the unblocking toothed ring 502 pushes out the Chinese herbal medicine particles accumulated in the gap between the crushing tooth 302 and the crushing roller 303, the hammer 304 drives the moving ring 701 to move through the connecting rod. The elastic element of the moving ring 701 is compressed. The moving ring 701, through the cooperation of the protrusion and the arc groove, makes the hammer 304 rotate during the upward movement. The hammer 304 drives the adjacent scraper 801 to rotate, scraping off the Chinese herbal medicine particles attached to the upper side of the unblocking toothed ring 502, preventing the Chinese herbal medicine particles from adhering to the unblocking toothed ring 502 and resetting. This results in a large number of Chinese herbal medicine particles still remaining between the crushing tooth 302 and the crushing roller 303 after cleaning, thus affecting the cleaning effect of the unblocking toothed ring 502 on the crushing tooth 302 and the crushing roller 303.

[0053] In summary, the invention includes, but is not limited to, the above embodiments. Any equivalent substitutions or partial improvements made under the spirit and principles of this invention shall be considered to be within the protection scope of this invention.
