Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical processing technology, and in particular to a dustproof multi-stage vibrating screen for processing Chinese herbal medicine slices. Background Technology

[0002] The multi-stage vibrating screen for processing Chinese medicinal herbs is a specialized screening device used in the production process of Chinese medicinal herbs. It adopts a multi-layer screen design, which can simultaneously perform multi-stage grading of medicinal materials, thereby improving production efficiency. The equipment is equipped with a dustproof device to effectively prevent dust from flying, ensuring a clean production environment and the health of operators. In addition, the vibrating screen is characterized by simple operation, convenient maintenance, and high screening accuracy. It is widely used in the selection and grading of Chinese medicinal materials and is an indispensable production equipment for modern Chinese medicinal herb processing enterprises.

[0003] A search revealed that the document with publication number "CN215141970U" mentions "This utility model provides a multi-stage vibrating screening device for rice processing, including a processing equipment body and a cleaning component; the cleaning component is fixed on the processing equipment body, and the cleaning component includes a mounting plate, a motor, a first pulley, a rotating rod, a second pulley, a transmission plate, a transmission rod, a sliding cylinder, a sliding rod, a sliding block, a sliding groove, and a collision block; wherein, the mounting plate is fixed on the processing equipment body, and the motor is fixed on the mounting plate." In use, the rice... The multi-stage vibrating screen for grain processing uses a motor to drive a sliding rod to move left and right. This movement causes the sliding rod to collide with a collision block, which in turn vibrates the processing equipment itself. This vibration, in turn, causes the screen plate inside the processing equipment to vibrate, dislodging dust and rice husks from the screen plate. This prevents rice husks from adhering to the screen plate and affecting its ability to screen rice, thus avoiding clogging. However, Chinese medicinal herbs are mostly in powder form, which can absorb moisture and clump together. This makes it difficult to separate these clumps during the screening process, leading to waste.

[0004] Therefore, we provide a dustproof multi-stage vibrating screen for processing Chinese herbal medicine slices to solve the above problems. Utility Model Content

[0022] 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.

[0023] Example 1

[0024] Please see Figure 1-4 As shown, this utility model provides a technical solution: a dustproof multi-stage vibrating screen for processing Chinese herbal medicine slices, including a material distribution bin 1 and a multi-stage vibrating screening mechanism 2, wherein the multi-stage vibrating screening mechanism 2 is installed on the inner side of the material distribution bin 1.

[0025] The multi-stage vibrating screening mechanism 2 includes a qualified material discharge component 21, a multi-stage screening component 22, and a material distribution and discharge component 23. The qualified material discharge component 21 is provided on the lower side of the material distribution bin 1, the multi-stage screening component 22 is provided on the inner side of the material distribution bin 1, and the material distribution and discharge component 23 is provided on the outer side of the material distribution bin 1.

[0026] Furthermore, the qualified material discharge assembly 21 includes an agglomeration chamber 211 and a discharge pipe 212. The agglomeration chamber 211 is installed at the bottom inner side of the distribution chamber 1, and the discharge pipe 212 is welded to the lower side of the agglomeration chamber 211. When needed, the agglomeration chamber 211, which is screened to the appropriate size, will eventually gather in the agglomeration chamber 211, and then the qualified Chinese herbal medicine granules in the agglomeration chamber 211 will be discharged along the discharge pipe 212.

[0027] Furthermore, the multi-stage screening assembly 22 includes a reciprocating vibrator 221, a vibrating reciprocating disc 222, a mounting sleeve 223, a reciprocating spring sleeve 224, and a multi-stage screen 225. The reciprocating vibrator 221 is welded to the inner side of the distribution bin 1. The vibrating reciprocating disc 222 is installed on the upper side of the reciprocating vibrator 221. The mounting sleeve 223 is welded to the upper side of the vibrating reciprocating disc 222. The reciprocating spring sleeve 224 is provided on the inner side of the mounting sleeve 223. The multi-stage screen 225 is provided on the outer side of the reciprocating spring sleeve 224. When needed, the reciprocating vibrator 221 will drive the vibrating reciprocating disc 222 to perform reciprocating vibration, which will cause the multi-stage screen 225 on the lower side to vibrate slightly, thereby avoiding the finer Chinese herbal medicine particles from being crushed again, resulting in damage.

[0028] Furthermore, the reciprocating spring sleeve 224 and the mounting sleeve 223 are connected by a slot. The mounting sleeve 223 and the multi-stage screen 225 form a reciprocating structure through the reciprocating spring sleeve 224. When needed, the reciprocating spring sleeve 224 in the mounting sleeve 223 will reciprocate with the vibration of the reciprocating disc 222. With the vibration, qualified particles will fall off naturally, while clumps of particles will be shaken apart, thereby improving the overall pass rate.

[0029] Furthermore, the material distribution and discharge assembly 23 includes a discharge port 231, a rotating shaft 232, and a dust sealing plate 233. The outer side of the multi-stage screen 225 is provided with a discharge port 231, and the outer side of the discharge port 231 is equipped with a rotating shaft 232. The lower side of the rotating shaft 232 is equipped with a dust sealing plate 233. After screening, the granules that are heavily damp and have formed agglomerates can be discharged along the discharge port 231, while the dust sealing plate 233 can prevent dust leakage during screening.

[0030] Example 2

[0031] Please see Figure 1 and Figure 2As shown in the first embodiment, as another implementation of this utility model, a dustproof component 3 is installed on the upper side of the material distribution bin 1. The dustproof component 3 includes a top cover 31, a dust extraction port 32, and a dust collector 33. The top cover 31 is connected to the upper side of the material distribution bin 1 by a slot. The dust extraction port 32 is provided on the upper side of the top cover 31. The dust collector 33 is provided on the right side of the material distribution bin 1. When it is needed, the sealed top cover 31 can effectively prevent dust leakage and avoid displacement due to vibration, thus avoiding the risk of falling.

[0032] Furthermore, the dust collector 33 is connected to the dust extraction port 32 by a pipe. The dust collector 33 is an activated carbon dust collector. When needed, the dust collector 33 can suck away the floating dust particles from the distribution bin 1 through the dust extraction port 32, thereby avoiding the problem of too much dust and poor distribution effect, and improving the purity of Chinese herbal medicine granules.

[0033] Working principle: A dustproof multi-stage vibrating screen for processing Chinese herbal medicine slices is moved to the working position. In use, firstly, the dispensing bin 1 is placed in the desired position, and then the top cover 31 is placed on top of the dispensing bin 1. Next, the Chinese herbal medicine slices are poured into the dispensing bin 1 through the holes in the top cover 31. Secondly, the slices will first contact the first-layer multi-stage screen 225. Slices of the correct size will then fall onto the second-layer multi-stage screen 225. At this point, the reciprocating vibrator 221 will vibrate the second-layer multi-stage screen 225 through the vibrating reciprocating disc 222. The screening process involves the reciprocating disc 222 vibrating, which in turn causes the reciprocating spring sleeve 224 inside the sleeve 223 to vibrate, thus performing the screening. As the screening proceeds, qualified medicinal slices fall into the collection chamber 211 and are then discharged through the discharge pipe 212. In the third step, the dust generated during the screening process is absorbed by the dust collector 33 through the dust extraction port 32. Finally, after the screening is completed, unqualified particles can lift the dust sealing plate 233 outside the discharge hopper 231 along the rotating shaft 232 and be discharged from the multi-stage screen 225. This completes the process of using a dustproof multi-stage vibrating screen for processing Chinese medicinal slices.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
