Powder filtration devices, as an important laboratory piece of equipment, play a crucial role in the extraction, preparation, and quality control of Chinese medicinal herbs.

[0003] In existing technologies, the filtration of Chinese medicine powders mostly uses funnel-type filter devices or vibrating screens with a single filter screen. A single filter screen can only achieve a single level of filtration. If different particle sizes of powder are required, the filter screen needs to be replaced multiple times, which is cumbersome and inefficient. Moreover, when the amount of Chinese medicine powder added at one time exceeds the filter screen's capacity, the powder easily accumulates on the filter screen, forming "clumps" that clog the filter screen pores and reduce the filtration effect of the device, making it difficult to meet practical needs. Therefore, we propose a powder filtration device for Chinese medicine research and development to solve the above-mentioned problems. Utility Model Content

[0020] Beneficial effects

[0021] This invention provides a powder filtration device for traditional Chinese medicine research and development. Compared with the prior art, it has the following advantages:

[0022] This powder filtration device for traditional Chinese medicine research utilizes multiple stacked second annular covers with internal sieves of increasing mesh size from top to bottom. It can separate powders of different particle sizes in a single operation, eliminating the need for repeated filter replacements and significantly improving experimental efficiency.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-3 As shown:

[0029] A powder filtration device for research and development of traditional Chinese medicine includes a support 101;

[0030] The housing base 103 is mounted on the bracket 101;

[0031] An annular disk 104 is fixedly installed on the outer surface of the housing base 103, and multiple sets of strong springs 105 arranged in annular and equidistant order are installed between the annular disk 104 and the bracket 101.

[0032] The vibrator 102 is fixedly installed at the bottom of the housing base 103;

[0033] The first annular cover 106 is placed at the opening of the housing base 103, and a sealing plate 108 is fixedly installed inside the first annular cover 106;

[0034] Multiple sets of second annular clips 107 are stacked on top of the first annular clip 106 in sequence, and a screen plate 109 is fixedly installed on the inner side wall of the second annular clip 107. The first annular clip 106, the second annular clip 107 and the top cover plate 110 are all designed with a convex structure to facilitate interlocking.

[0035] The mesh size of the 109-mesh screens increases sequentially from top to bottom.

[0036] Top cover 110 is snapped onto the topmost second annular cover 107;

[0037] Locking mechanism 2, provided on annular disk 104, is used to limit and lock the first annular cover 106, the second annular cover 107 and the top cover plate 110. Locking mechanism 2 includes a mounting base 201 fixed on the upper surface of annular disk 104. The mounting base 201 is provided with an adjusting screw 202. One end of the adjusting screw 202 is rotatably connected to the mounting base 201 through a bearing, and the other end is rotatably connected to the top of the mounting base 201 through a bearing and extends to the outside of the mounting base 201. The mounting base 201 is provided with a pressing plate 203. The pressing plate 203 is threadedly connected to the adjusting screw 202 through a threaded hole. Both sides of the pressing plate 203 are in contact with the inner sidewall of the mounting base 201.

[0038] A quantitative dispensing mechanism 3 is installed on the top cover plate 110 and is used to quantitatively dispense Chinese medicine powder. The quantitative dispensing mechanism 3 includes a hopper cover 301 fixed on the upper surface of the top cover plate 110. A cap 302 is provided at the top opening of the hopper cover 301. A symmetrically arranged arc-shaped plate 303 is fixedly installed in the bottom cavity of the hopper cover 301. A separator rod 304 is provided between the two sets of arc-shaped plates 303. A motor 305 that drives the separator rod 304 to rotate is fixedly installed on one side of the hopper cover 301. The output end of the motor 305 is fixedly connected to one end of the separator rod 304. The end of the separator rod 304 can fit against the side wall of the arc-shaped plate 303. A discharge port corresponding to the bottom discharge port of the hopper cover 301 is opened on the top cover plate 110.

[0039] In this implementation scheme: the powder filtration device for TCM research and development has a first annular cover 106 placed at the opening of the housing 103, with its convex structure fitting the edge of the housing 103; multiple sets of second annular covers 107 are stacked sequentially on top of the first annular cover 106 through their convex structures, forming a graded filtration channel with increasing mesh size of the sieve disc 109 from top to bottom; the top cover 110 is engaged with the topmost second annular cover 107, completing the sealing of the entire filtration chamber, preventing dust from occurring during the filtration process, ensuring the laboratory environment, and meeting the actual use requirements;

[0040] The adjusting screw 202 on the rotating mounting base 201 is connected to the adjusting screw 202 through the threaded hole and the extrusion plate 203 is in contact with the inner wall of the mounting base 201 on both sides, which restricts the degree of rotation. The rotational motion of the adjusting screw 202 is converted into the vertical lifting motion of the extrusion plate 203. When the extrusion plate 203 descends, it tightly presses the top cover plate 110 and the edges of each annular cover to ensure that there is no relative displacement of each component during the vibration filtration process, avoids powder leakage, and ensures the stability of the clamping.

[0041] The Chinese medicine powder is poured into the hopper cover 301, and the top is sealed by the cap 302 to prevent dust. The symmetrical arc plate 303 at the bottom of the hopper cover 301 forms a funnel-shaped channel, guiding the powder to gather in the center. The motor 305 drives the separator rod 304 to rotate. When the separator rod 304 is in contact with the side wall of the arc plate 303, the feeding channel is closed. When the separator rod 304 rotates to separate from the arc plate 303, a quantitative feeding port is formed. The powder enters the filter chamber through the feeding port of the top cover plate 110. By controlling the speed of the motor 305 and the rotation angle of the separator rod 304, the amount of powder fed per unit time can be precisely adjusted to avoid excessive accumulation.

[0042] The vibrator 102 is fixed to the bottom of the housing 103. When working, it generates high-frequency vibration. The vibration is transmitted through the housing 103 to the first annular cover 106 and the stacked second annular cover 107.

[0043] Multiple sets of annular equidistant high-strength springs 105 between the annular disk 104 and the support 101 undergo elastic deformation during vibration, which not only buffers the impact of vibration on the support 101, but also amplifies the vibration amplitude of the filter cavity through resonance effect, thereby enhancing the dispersion and sieving ability of powder.

[0044] The powder first contacts the topmost screen 109 with the smallest mesh size, where large particles are trapped, and small particles pass through the screen and enter the lower layer under vibration. The lower screen 109 has a larger mesh size, which further traps medium-sized particles. The finest particles finally pass through the bottom screen and fall onto the sealed plate 108 inside the first annular cover 106, thus collecting the finest particles. Multiple screens 109 on the second annular cover 107 have different mesh sizes, which can screen and filter different particles. The filtered Chinese medicine powder particles are aggregated on the corresponding screens 109 of the second annular cover 107.

[0045] This solution utilizes multiple stacked second annular covers 107, each containing a screen disk 109 with an increasing mesh size from top to bottom. This allows for the separation of powders of different particle sizes in a single operation, eliminating the need for repeated filter replacements and significantly improving experimental efficiency. The number of second annular covers 107 and the mesh size combination of the screen disks 109 can be adjusted according to research and development needs to meet filtration requirements across different particle size ranges, thus broadening its applicability. The vibrator 102, in conjunction with a powerful spring 105, generates high-frequency vibration, ensuring the powder on the screen disk 109 remains dispersed, preventing static accumulation and clumping. Simultaneously, the vibration causes the powder particles to continuously change their direction of movement, increasing the probability of contact with the screen and accelerating sieving. The quantitative dispensing mechanism 3 precisely controls the powder dispensing speed and total amount, ensuring the powder load on the screen disk 109 is within a reasonable range, preventing filter clogging due to excessive powder intake from the source, improving the device's effectiveness, and meeting practical application requirements.

[0046] It should be noted that: Adjustment component 3 and limit component 4 have been added to this application document. All electrical equipment involved in this product is powered by an external power source. The solution also includes an electrical control cabinet, which is installed on the equipment. During use, each electrical device can be started and operated separately through the electrical control cabinet. The power connection method of each electrical device is an existing mature technology and is well known to those skilled in the art. It will not be described in detail here.

[0047] Furthermore, all content not described in detail in this specification is prior art known to those skilled in the art;

[0048] The vibrator 102 is located directly below the housing base 103, and its vibration direction is transmitted vertically.

[0049] The bracket 101 can be fixed in a designated position by bolts. The connecting screws between the vibrator 102 and the housing 103 can be fine-threaded or used with spring washers. After tightening, they generate continuous elastic force to prevent the threads from loosening. By tightening the screws with a preset torque, the connecting surfaces are ensured to fit tightly, reducing gaps and shaking during vibration and lowering the risk of screw loosening.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
