Description

Technical Field

[0001] The utility model relates to the technical field of pulverizers, in particular to ultrafine pulverizing equipment. Background Art

[0002] With the rapid advancement of science and technology, the application scope of modern machinery such as grinders is becoming increasingly extensive, especially in the processing of Traditional Chinese Medicine (TCM). In the pursuit of maximizing the efficacy of medicinal materials, many require meticulous processing to fully release their active ingredients. Traditional processing methods are particularly limited for some hard and complex herbs, such as mother-of-pearl. Achieving the ideal crushing effect for these herbs often requires multiple steps: first, a traditional grinder is used for initial crushing, reducing them to smaller particles. However, this is only the first step and is far from sufficient for subsequent applications.

[0003] Next, in order to further improve the fineness of the medicinal materials and the efficiency of drug release, it is often necessary to resort to a more tedious manual operation - the mortar water fly method. In this step, workers need to patiently place the initially crushed medicinal materials in a mortar, add water and grind them repeatedly until the required fineness is reached. However, this process is not only labor-intensive and consumes a lot of manpower costs, but also time-consuming and inefficient. More importantly, even after such efforts, the final powder often still has problems with uneven particle size and coarse powder shape, which directly affects the quality of the medicinal materials and the uniformity and stability of subsequent preparations, which may have an adverse effect on the efficacy of the medicine.

[0017] As a further improvement of the above technical solution, each component of the utility model is arranged on a support frame.

[0018] Compared with the related art, the beneficial effects of the present invention are:

[0019] During use, the ultrafine pulverization equipment provided by the present invention first starts the driving component to drive the pulverization component in the pulverization tank to enter the working state. Then, the operator slowly puts the Chinese medicinal materials to be processed into the pulverization tank through the first feed port. Under the action of the pulverization component, these raw materials undergo a series of fine grinding and pulverization processes until the expected fineness requirements are reached. Since the second feed port of the solid-gas separation tank is connected to the first discharge port of the pulverization tank through the feed pipe. The negative pressure device located at the negative pressure port of the solid-gas separation tank is started, and a stable negative pressure environment can be formed in the tank. This negative pressure environment can extract the material powder with moderate particle size and meeting the requirements in the pulverization tank from the first discharge port and enter the solid-gas separation tank along the feed pipe. In the solid-gas separation tank, the material powder collides with the tank wall under the action of high-speed airflow, and then slowly falls to the bottom of the tank under the action of gravity. This process not only achieves the initial separation of material and air, but also further refines the particle size distribution of the material powder. Finally, when a sufficient amount of qualified material powder has accumulated in the solid-gas separation tank, the operator simply opens the second discharge port at the bottom of the tank to easily discharge and collect the powder. The entire discharge process is fast and smooth, effectively avoiding material waste and environmental pollution.

[0020] It is worth noting that for any larger particles still in the pulverizer, the pulverizer assembly will continue to operate, repeatedly grinding them until they meet acceptable standards. This process ensures the uniformity and consistency of the final product, meeting users' demands for high-quality Chinese herbal medicine powder.

[0021] Furthermore, by adjusting the operating power of the vacuum device, users can easily and precisely control the particle size of the material being pumped. This feature not only improves the adaptability and flexibility of the device, but also provides users with a more personalized operating experience.

[0032] like Figure 1 As shown, this embodiment provides an ultrafine grinding device for grinding Chinese medicinal materials, including a grinding tank 100, a driving component 200, and a solid-gas separation tank 300.

[0033] The crushing tank 100 is provided with a first feed port 110 and a first discharge port 120, and a crushing assembly is provided inside the crushing tank 100; the driving assembly 200 is in transmission cooperation with the crushing assembly; the side wall of the solid-gas separation tank 300 is provided with a second feed port 310, and the lower end of the solid-gas separation tank 300 is provided with a second discharge port 320, the first discharge port 120 is connected to the second feed port 310 through a feeding pipe 130, and the upper end of the solid-gas separation tank 300 is provided with a negative pressure port 330, and the negative pressure port 330 is externally connected to a negative pressure device 540.

[0034] The ultrafine grinding equipment provided in this embodiment, during use, first starts the driving component 200, so that it drives the grinding component in the grinding tank 100 to enter the working state. Then, the operator slowly puts the Chinese medicinal materials to be processed into the grinding tank 100 through the first feed port 110. Under the action of the grinding component, these raw materials undergo a series of fine grinding and crushing processes until the expected fineness requirements are reached. Because the second feed port 310 of the solid-gas separation tank 300 is connected to the first discharge port 120 of the grinding tank 100 through the feed pipe 130. Start the negative pressure device 540 located at the negative pressure port 330 of the solid-gas separation tank 300, and a stable negative pressure environment can be formed in the tank. This negative pressure environment can extract the material powder with moderate particle size and meeting the requirements in the grinding tank 100 from the first discharge port 120, and enter the interior of the solid-gas separation tank 300 along the feed pipe 130. Inside the solid-gas separation tank 300, the material powder collides with the tank wall under the action of high-speed airflow, and then slowly falls to the bottom of the tank under the action of gravity. This process not only achieves the initial separation of the material and air, but also further refines the particle size distribution of the material powder. Finally, when a sufficient amount of qualified material powder has accumulated in the solid-gas separation tank 300, the operator can simply open the second discharge port 320 at the lower end of the tank body to easily discharge and collect the powder. The entire discharge process is fast and smooth, effectively avoiding material waste and environmental pollution.

[0035] Furthermore, for any larger particles still present in the crushing tank 100, the crushing assembly will continue to operate, repeatedly grinding them until they meet acceptable standards. This process ensures uniformity and consistency in the final product, meeting user demands for high-quality Chinese medicinal material powder while also reducing material waste.

[0036] Furthermore, when crushing different types of medicinal materials, the operating power of the negative pressure device 540 can be adjusted according to different needs, thereby achieving precise control of the particle size of the suctioned material. This function not only improves the adaptability and flexibility of the equipment, but also provides users with a more personalized operating experience.

[0037] In some implementations, the drive assembly 200 includes a drive motor 210, which is coupled to the pulverizing assembly via a transmission assembly 400. The transmission assembly 400 includes a gearbox 410, with the drive motor 210 connected to the low-speed shaft of the gearbox 410, and the pulverizing assembly's rotating shaft 420 connected to the high-speed shaft of the gearbox 410. By interposing the gearbox 410 between the drive motor 210 and the pulverizing assembly, the engagement and disengagement of the multi-stage gears within the gearbox 410 enable speed regulation and torque amplification during power transmission. Specifically, the output shaft of the drive motor 210 is tightly connected to the low-speed shaft of the gearbox 410, ensuring lossless transmission of the power generated by the motor to the gearbox 410. Within the gearbox 410, after a complex series of gear transmission processes, the power is directed to the high-speed shaft of the gearbox 410. At this point, the power has been converted from low speed and high torque to high speed and low torque to meet the power characteristics required by the pulverizing assembly. The rotating shaft 420 of the crushing assembly is connected to the high-speed shaft of the gearbox 410 to ensure seamless transmission of power.

[0038] In some embodiments, the pulverizing assembly includes a grinding wheel, which is disposed in the pulverizing jar 100. A grinding rail corresponding to the grinding wheel is provided on the inner wall of the pulverizing jar 100. The grinding wheel is mounted on the rotating shaft 420. The rotating shaft 420 drives the grinding wheel to rotate relative to the grinding rail to grind and crush the material in the pulverizing jar 100. Specifically, as the grinding wheel continues to rotate, the material is subjected to continuous extrusion, shearing and friction in the pulverizing jar 100, gradually changing from larger particles to fine powder. At the same time, due to the guidance of the grinding rail, the movement trajectory of the material in the pulverizing jar 100 is effectively controlled, avoiding the disordered accumulation and jamming of the material during the grinding process, thereby improving the pulverizing efficiency and grinding quality. In summary, the pulverizing assembly achieves efficient and fine grinding and crushing of the material through the synergistic effect of the grinding wheel and the grinding rail.

[0039] In some embodiments, the ultrafine grinding equipment further includes a filtering device 500, wherein a filter cavity is provided in the filtering device 500, wherein a filter bag is provided in the filter cavity, wherein a plurality of filter bags are provided and the filter cavity is divided into an upper portion and a lower portion, wherein the side wall of the lower portion is provided with an air suction port 510, and the bottom of the lower portion is provided with a slag outlet 520, wherein the air suction port 510 is connected to the negative pressure port 330 through an air pipe 340, and an air outlet 530 is provided on the upper portion, and the air outlet 530 is connected to the negative pressure device 540; when the negative pressure device 540 is started, the air is pumped from the crushing tank 100 to the Most of the material particles in the solid-gas separation tank 300 fall to the bottom of the solid-gas separation tank 300, while a small number of fine material particles will pass through the air pipe 340 with the air flow into the lower part of the filter cavity of the filter device 500. When the air flow passes through the filter bag, the fine material particles will be isolated by the filter bag in the lower part of the filter cavity, thereby greatly reducing the dust content of the air flow extracted from the filter device 500 by the negative pressure equipment 540. On the one hand, it can effectively reduce the pollution to the environment of this embodiment, and on the other hand, it is convenient for the centralized collection and treatment of the material dust collected by the filter device 500 to reduce waste.

[0040] In some implementations, the second discharge port 320 and the slag discharge port 520 are provided with an electrically controlled valve 521 to facilitate automatic control of the discharge of material from the second discharge port 320 or the discharge of slag from the slag discharge port 520, thereby reducing the workload of staff and improving production efficiency and safety.

[0041] In some implementations, reinforcing ribs 570 are evenly distributed on the outer sidewall of the filter device 500 to improve the shell strength of the filter device 500 .

[0042] In some embodiments, the ultrafine grinding equipment further includes an electrical control box 150, which is electrically connected to the drive assembly 200, the negative pressure device 540, and the electrically controlled valve 521, respectively, so that the staff can centrally control the working status of each component of this embodiment through the electrical control box 150, which is convenient to operate and improves production efficiency.

[0043] In some embodiments, the filter device 500 is provided with an upper cleaning door 550 and a lower cleaning door 560 corresponding to the upper part and the lower part, respectively, so that the operator can regularly clean and maintain the interior of the filter device 500 and the filter bag by opening the upper cleaning door 550 and the lower cleaning door 560.

[0044] In some implementations, a feed hopper 111 is installed on the first feed port 110 , and the opening area of the feed hopper 111 away from the first feed port 110 is larger than the cross-sectional area of the first feed port 110 , making it easier for staff to feed materials into the feed hopper 111 .

[0045] In some implementations, each of the aforementioned components is mounted on a support frame 140. The support and isolation provided by the support frame 140 not only mitigates the adverse effects of uneven floor surfaces or humidity fluctuations on component performance, but also significantly reduces the risk of wear and failure due to long-term uneven force. Furthermore, the design of the support frame 140 fully considers heat dissipation requirements, ensuring that heat generated by each component during operation can be dissipated promptly, further ensuring efficient and stable operation of the system.
