Description

Technical Field

[0001] The present invention relates to the technical field of impurity removal equipment, and more specifically, to an efficient impurity removal device in the process of traditional Chinese medicine processing. Background Art

[0002] During the production process of traditional Chinese medicine, impurity removal is required. Common impurity removal methods include:

[0003] I. Selection: It refers to the method of manually picking impurities by hand, picking out non-medicinal parts, picking out visible impurities that are not easily removed by other methods, such as sawdust, sand, weeds, branches, etc., picking out rotten and insect-infested and other deteriorated medicinal materials, and grading by size. II. Screening: According to the different volume sizes of the drug and impurities, different specifications of sieves and sieves are selected, and the impurities are removed by sieving; or screening and grading are carried out using sieves with different pore sizes to make the size specifications tend to be consistent (equipment: mostly mechanical operations now - oscillating sieve machines, small electric sieve machines, etc.). III. Wind selection: Utilize the different specific gravities (weights) of the drug and impurities, and through winnowing (generally, a dustpan or a windmill can be used), remove impurities and non-medicinal parts with the help of wind. IV. Water selection: Water selection is a common method of selecting or floating impurities by passing the drug through water. Water selection can be divided into three methods: washing, rinsing, and soaking and floating. (1) Washing: It means washing away the soil, dust, mildew spots or other unclean things on the surface of the medicinal materials with clean water; (2) Rinsing: It means rinsing the sand or impurities attached to the surface of the medicinal materials with a large amount of clean water (generally used to separate impurities from the medicinal materials, removing floating skins, shells and other impurities and sediment in a small container); (3) Soaking and floating: It means soaking the drug in a large amount of clean water for a long time; or putting the medicinal materials in a bamboo basket and floating them in clean running water for a long time (generally used to float away toxins, salts or fishy smells).

[0004] In the specific industrial production of traditional Chinese medicine, different impurity removal methods need to be selected according to different types of traditional Chinese medicine, so a large number of different equipment are involved, consuming high costs. In view of this, we propose an efficient impurity removal device in the process of traditional Chinese medicine processing, which uses a multi-level and multi-process impurity removal device from top to bottom, integrating screening, wind selection and water selection impurity removal processes, and can select different impurity removal processes according to different types of medicinal materials without equipment replacement, which is more efficient.

[0005] The information disclosed in this background art section is only intended to enhance the overall understanding of the present invention and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art. Summary of the Invention

[0006] To solve the problems raised in the above-mentioned background technology, the technical solution of the present invention proposes an efficient impurity removal device in the processing of traditional Chinese medicinal materials. By using a multi-level and multi-process impurity removal device from top to bottom, which integrates screening, air separation, and water separation impurity removal processes, different impurity removal processes can be selected according to different types of medicinal materials without equipment replacement, making it more efficient.

[0007] The present invention proposes an efficient impurity removal device in the processing of traditional Chinese medicinal materials, including an operation part for impurity removal operations and a driving part for controlling and driving the device.

[0008] In the technical solution of the present invention, the operation part includes a screening layer for screening the size particles of medicinal materials, a friction layer for friction treatment of impurities on the surface of medicinal materials, an air separation layer for air separation of impurities in medicinal materials, a water separation layer for water separation of impurities in medicinal materials, a drying layer for drying after water separation, and a discharging layer for discharging.

[0009] Further, the screening layer includes a feed inlet and a screening bin. A transmission turntable is installed inside the screening bin. Three groups of guiding components are installed above the transmission turntable. A material guiding port is installed at the center of the transmission turntable. A first material guiding pipe and an impurity discharging pipe are installed and connected below the material guiding port.

[0010] Further, a first transmission belt is sleeved and installed outside the transmission turntable. The first transmission belt is driven by the driving part to drive the transmission turntable to rotate and convey medicinal materials. The three groups of guiding components each include a guiding rotating shaft group and a motor telescopic shaft. The three groups of guiding rotating shaft groups are respectively located above the transmission turntable to guide the moving direction of the medicinal materials conveyed by the transmission turntable. The motor telescopic shaft is used to control the distance between the bottom end of the guiding rotating shaft group and the transmission turntable through a motor.

[0011] Furthermore, the vertical distance between the bottom ends of the three groups of the guiding rotating shaft groups and the transmission turntable is different, so that medicinal materials and impurity particles of different sizes are respectively screened and pass through the spaces between different groups of the guiding rotating shaft groups and the transmission turntable. The material guiding ports respectively include a large particle impurity port, a qualified port and a small particle impurity port. The large particle impurity port is located on one side of the guiding rotating shaft group with the largest distance from the transmission turntable. The largest distance is the maximum limit size of qualified medicinal materials. Medicinal material particles and impurity particles exceeding the largest distance are blocked by the guiding rotating shaft group and guided into the large particle impurity port. The qualified port is located on one side of the guiding rotating shaft group with a medium distance from the transmission turntable. The medium distance is the minimum limit size of qualified medicinal materials. Medicinal material particles exceeding the minimum limit size are blocked by the guiding rotating shaft group and guided into the qualified port. The small particle impurity port is located on one side of the guiding rotating shaft group with the smallest distance from the transmission turntable. The smallest distance is the sliding contact between the guiding rotating shaft group and the transmission turntable. Impurity particles smaller than the medium distance are blocked by the guiding rotating shaft group and guided into the small particle impurity port. The first material guiding pipe is communicated with the qualified port, and the impurity discharge pipe is communicated with the large particle impurity port and the small particle impurity port.

A second material guiding pipe is connected below the lower friction layer discharging port. The first material guiding turntable rotates to convey the medicinal materials entering through the first material guiding pipe to the lower friction layer discharging port for discharging into the second material guiding pipe. Upper friction layer abrasive particles and lower friction layer abrasive particles are respectively arranged on the upper friction layer and the lower friction layer. The upper friction layer abrasive particles and the lower friction layer abrasive particles are used for rubbing the surface impurities of the medicinal materials during the conveying process to make them fall off and become loose.

[0013] Further, the air separation layer includes an upper air separation layer and a lower air separation layer.

A lower air separation layer discharging port is formed on the lower air separation layer. A third material guiding pipe is connected below the lower air separation layer discharging port. The second material guiding turntable rotates to convey the medicinal materials entering through the second material guiding pipe to the lower air separation layer discharging port for discharging into the third material guiding pipe. Upper air separation layer through holes and lower air separation layer through holes are respectively formed on the upper air separation layer and the lower air separation layer. An air box assembly is installed above the upper air separation layer through hole to provide the air flow required for air separation. The upper air separation layer through hole and the lower air separation layer through hole are used for passing the air separation air flow. An exhaust assembly is further installed below the lower air separation layer through hole for exhausting air during the air separation process.

[0014] Further, the water separation layer includes an upper water separation layer and a lower water separation layer.

A lower water separation layer discharging port is formed on the lower water separation layer. A fourth material guiding pipe is connected below the lower water separation layer discharging port. The third material guiding turntable rotates to convey the medicinal materials entering through the third material guiding pipe to the lower water separation layer discharging port for discharging into the fourth material guiding pipe. Upper water separation layer through holes and lower water separation layer through holes are respectively formed on the upper water separation layer and the lower water separation layer. A water tank assembly is installed above the upper water separation layer through hole to provide the water flow required for water separation. The upper water separation layer through hole and the lower water separation layer through hole are used for passing the water separation water flow. A drainage assembly is further installed below the lower water separation layer through hole for draining water during the water separation process.

[0015] Further, the drying layer includes an upper drying layer and a lower drying layer. A fourth feeding turntable is installed between the upper drying layer and the lower drying layer.

This embodiment adopts a multi-layer structure from top to bottom, integrating screening, air separation, and water separation impurity removal processes. Different impurity removal processes can be selected according to different types of medicinal materials without equipment replacement, which is more efficient. On the other hand, this embodiment utilizes the screening, air separation, and water separation process structure design of the upper, middle, and lower multi-layer structures.
