Description

Technical Field

[0001] This utility model relates to the field of medicinal herb processing technology, and in particular to a wind-separating structure for separating medicinal herb processing debris. Background Technology

[0002] During the processing of Chinese medicinal herbs, light dust easily adheres to the surface of the herbs, and larger impurities such as fragments may also be mixed in. If these fragments and impurities are not completely separated, they will not only affect the purity and appearance of the herbs, but may also reduce their efficacy and even adversely affect subsequent processing and storage. Therefore, the separation of fragments and impurities is a key step in the processing of medicinal herbs.

[0003] Currently, the most common methods for separating medicinal herb fragments in the industry are single-stage air classification or simple screening. Single-stage air classification devices typically consist of only one set of fans and separation plates, using a single airflow force to classify the material. This method has significant drawbacks: firstly, a single airflow force cannot simultaneously meet the separation requirements of light dust and larger impurities. If the airflow force is too weak, it will be difficult to blow away larger impurities; if the airflow force is too strong, the medicinal herb fragments will easily be blown away along with the impurities, resulting in fragment loss. Secondly, the material slides down rapidly during the feeding process, resulting in a short contact time with the airflow. Some light dust is not fully separated and is discharged with the medicinal herb fragments, leading to incomplete separation.

[0004] Some devices add a screening structure to the air separation to filter out larger impurities. However, this type of structure still has shortcomings: First, the screen is easily clogged by materials, requiring frequent manual cleaning and affecting processing efficiency. Second, the screen and air separation components lack coordinated design, and the filtered material enters the air separation area directly. Due to improper falling angle, airflow turbulence can easily occur, causing the separated impurities to mix back into the medicinal slices. Third, most of the qualified medicinal slices after separation fall directly to the collection device without a buffer structure, which can easily cause the medicinal slices to break and reduce the finished product qualification rate.

[0005] In addition, the airflow guidance design of the existing air separation device is unreasonable. The airflow blown out by the fan is prone to forming eddies in the box, causing dust to spill out. This not only pollutes the processing environment, but may also cause air pressure imbalance in the box, further affecting the air separation accuracy.

[0006] In summary, existing herbal medicine fragment separation devices suffer from problems such as low separation accuracy, poor processing efficiency, easy loss of herbal medicine fragments, and turbulent airflow, making it difficult to meet the high-quality production requirements of herbal medicine processing. Therefore, there is an urgent need for an air separation structure that can achieve graded separation, prevent clogging, protect herbal medicine fragments, and provide stable airflow.

Detailed Implementation

[0023] The following is a detailed explanation with reference to the accompanying drawings.

[0024] Example 1

[0025] This utility model provides an air separation and air-guiding structure for separating debris during the processing of medicinal slices, such as... Figure 1As shown, the device includes a housing 100, which serves as the main body of the apparatus. A first air separation component 200 and a second air separation component 300 are disposed within the housing 100. An inlet 101 is located at the vertical end of the housing 100, near the first air separation component 200 and the second air separation component 300. The first air separation component 200 includes a first discharge plate 201 located vertically below the inlet 101 and a first air separation plate 202 cooperating with the first discharge plate 201 for air separation. A first fan 203 is disposed at the intersection of the first discharge plate 201 and the first air separation plate 202. The second air separation component 300 includes a second discharge plate 301 and a second air separation plate 302. The second discharge plate 301 has a plurality of sieve holes 304, and a waste chamber 305 is located vertically below the plurality of sieve holes 304. The sieve holes 304 are used to filter out impurities of larger mass. This invention achieves a preliminary division of labor in the "dual air separation" of processed food scraps by setting up a first air separation component 200 and a second air separation component 300, laying a structural foundation for subsequent graded separation of impurities. The feed inlet 101 is located at the vertical upper end of both air separation components, ensuring that the material can simultaneously cover both the first and second air separation components 200 and 300, improving material processing efficiency and avoiding congestion problems caused by single-component processing. The sieve holes 304 of the second discharge plate 301 cooperate with the waste chamber 305 below to pre-filter out larger impurities, reducing the processing load of subsequent air separation components and improving overall separation efficiency. The first and second air separation components 200 can perform graded air separation. The first air separation component 200 first separates dust on the food scraps, and then separates higher-quality impurities mixed in with the food scraps through several filter holes 304. The second air separation component 300 then performs secondary air separation on the scraps mixed in with the food scraps that the first air separation component 200 could not separate, thereby improving air separation efficiency.

[0026] According to a preferred embodiment, such as Figure 2 and Figure 3 As shown, a second fan 303 is located at the intersection of the second discharge plate 301 and the second air separator plate 302. The second fan 303 is located at the vertically downward end of the waste chamber 305. The airflow force of the second fan 303 is greater than that of the first fan 203, thus enabling the separation of different impurities. The first fan 203 is mainly used for air separation of light dust. The second fan 303 is mainly used for separating larger impurities mixed between the food slices. The second fan 303 and the first fan 203 form an "airflow classification" system. The low airflow force of the first fan 203 is suitable for separating light dust, while the high airflow force of the second fan 303 is suitable for separating larger impurities, achieving precise classification and separation of different types of impurities and improving the impurity separation accuracy. The second fan 303 can enhance the airflow intensity in the area of ​​the second air separator component 300, further strengthening the separation effect of larger impurities.

[0027] According to a preferred embodiment, the first discharge plate 201 is inclined away from the first blower 203. The first air separator 202 is inclined in the opposite direction to the first discharge plate 201. The horizontal height of the first air separator 202 is lower than that of the first discharge plate 201. The inclination of the first discharge plate 201 away from the first blower 203 guides the material to slide down slowly, prolonging the residence time of the material in the air separator area, allowing the first blower 203 sufficient time to blow away light dust. The first air separator 202 is inclined in the opposite direction to the first discharge plate 201 and is at a lower horizontal height, forming a "guide channel". Combined with the airflow of the first blower 203, it can accurately guide the blown light dust towards the first air separator 202, preventing dust diffusion and improving the separation efficiency of light impurities.

[0028] According to a preferred embodiment, a first collection chamber 204 is provided at the end of the first air separator 202 away from the first fan 203. The height of the first collection chamber 204 is flush with the highest point of the first air separator 202. This flush height ensures that light impurities guided by the first air separator 202 can smoothly enter the first collection chamber 204, preventing impurities from remaining or flowing back into the air separator area due to height differences, thus guaranteeing the collection effect of light impurities and reducing secondary pollution.

[0029] According to a preferred embodiment, a filter assembly 102 is provided on the side of the housing 100 near the first collection chamber 204. The filter assembly 102 is arranged perpendicular to the blowing direction of the first fan 203. The filter assembly 102 is used to guide the air blown by the first fan 203 and the second fan 303 out of the housing 100, avoiding dust spillage caused by airflow turbulence. The filter assembly 102 is arranged perpendicular to the blowing direction of the first fan 203, which can efficiently guide the airflow blown by the first fan 203 and the second fan 303 out of the housing 100, avoid airflow turbulence inside the housing 100, prevent the separated dust from spreading back to the slice area, and ensure a stable air separation environment. The orderly discharge of airflow can maintain the air pressure balance inside the housing 100, avoid the air pressure fluctuation affecting the air force stability of the first fan 203 and the second fan 303, and further ensure the consistency and accuracy of air separation.

[0030] According to a preferred embodiment, the second discharge plate 301 is inclined away from the second fan 303. The second air separator 302 is inclined in the opposite direction to the second discharge plate 301. The inclination angle of the second discharge plate 301 is smaller than that of the first discharge plate 201. The inclination of the second discharge plate 301 away from the second fan 303, and the inclination angle being smaller than that of the first discharge plate 201, can slow down the material's downward movement, providing sufficient time for the sieve holes 304 to filter large impurities, thereby improving the filtration success rate of large impurities. The second air separator 302 is inclined in the opposite direction to the second discharge plate 301, forming an "air separator channel" adapted to the airflow of the second fan 303, preparing the structure for subsequent separation of larger impurities, and ensuring that the material can accurately enter the air separator area of ​​the second air separator 302.

[0031] According to a preferred embodiment, a vibration assembly 103 and a drive motor for rotating the vibration assembly 103 are further provided on the side wall of the housing 100. At least two sides of the second discharge plate 301 have gaps with the side wall of the housing 100. The vibration assembly 103, made of flexible material, interferes with the sides of the second discharge plate 301 by rotating around the output shaft of the drive motor. During rotation, the vibration assembly 103 continuously impacts the second discharge plate 301, causing the material on the second discharge plate 301 to slide down. Higher-quality impurities fall through the sieve holes 304 into the waste chamber 305, while the medicinal slices fall onto the second air separator plate 302 along the second discharge plate 301. The rotating impact of the vibration assembly 103 on the second discharge plate 301 effectively prevents material from clogging the sieve holes 304, while accelerating the material's descent, preventing material accumulation on the second discharge plate 301, and improving material processing efficiency. The vibration can cause large impurities in the material to quickly pass through the sieve hole 304 and fall into the waste chamber 305, while pushing the medicinal slices smoothly to the second air separation plate 302, realizing the efficient separation of large impurities and medicinal slices. The flexible material vibration component 103 near the edge of the second discharge plate 301 can prevent damage to the second discharge plate 301 or the medicinal slices during impact.

[0032] According to a preferred embodiment, a second collecting chamber 306 is provided at the end of the second air separator 302 away from the second fan 303. The height of the second collecting chamber 306 is flush with the highest point of the second air separator 302. This flush height ensures that larger impurities separated by the second air separator 302 can smoothly enter the second collecting chamber 306, preventing impurities from remaining on the second air separator 302, preventing impurities from mixing again with qualified medicinal slices, and ensuring the purity of the medicinal slices.

[0033] According to a preferred embodiment, a guide member is provided vertically below one end of the second air separator 302 near the second fan 303. Several shock-absorbing protrusions are provided on the surface of the guide member. In this invention, the guide member can be configured as an inclined plate or an inverted triangle (not shown in the figures). The guide member is used to prevent the medicinal slices from breaking during their fall. The guide member can guide the qualified medicinal slices screened by the second air separator 302 to fall smoothly, avoiding direct drop and breakage, thus reducing processing losses. The shock-absorbing protrusions on the surface of the guide member can further buffer the impact force when the medicinal slices fall, maximizing the protection of the integrity of the medicinal slices and improving the quality and pass rate of the finished product.

[0034] According to a preferred embodiment, a third collection chamber 104 is provided vertically below the guide member in the housing 100. The third collection chamber 104 is located at the vertically lower end of the guide member and can directly receive qualified medicinal slices guided down by the guide member, achieving centralized collection of qualified medicinal slices, preventing them from scattering, and simplifying subsequent transfer and processing procedures, thus improving overall processing efficiency. It is understood that the side of the housing 100 is provided with opening and closing doors (not shown in the figure) corresponding to several collection chambers to facilitate the removal of impurities or processed medicinal materials from inside.
