Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine decoction piece processing technology, specifically a screening device for processing traditional Chinese medicine decoction pieces. Background Technology

[0002] Traditional Chinese medicine (TCM) decoction pieces are TCM herbs that have been processed according to TCM theory and processing methods, and can be directly used in TCM clinical practice. TCM decoction pieces include some sliced ​​herbs processed at the place of origin, whole medicinal herbs, and herbs that have been cut or processed. During the processing of TCM decoction pieces, methods such as baking, roasting, stir-frying, washing, soaking, rinsing, steaming, and boiling are used. In the final collection stage, dust and small particles of herbs formed during processing need to be removed to reduce the particle texture and improve the quality of the final TCM decoction pieces. Traditional TCM decoction piece processing screening devices mostly only allow for single-pass screening, making it difficult to ensure thorough removal of impurities and dust, thus reducing product quality. Therefore, we propose a TCM decoction piece processing screening device to solve the problems mentioned in the background. Utility Model Content

[0003] The purpose of this invention is to provide a screening device for processing Chinese herbal medicine slices, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a screening device for processing Chinese herbal medicine slices, comprising a support base, a screening cylinder mounted on the support end of the support base, a first screening screen mounted on the lower surface of the screening cylinder, a circulating screening component fixedly connected to and communicating with the right surface of the screening cylinder, a reflux component fixedly connected to the circulating screening component, a feed hopper fixedly connected to and communicating with the rear side of the screening cylinder, a first motor fixedly mounted at the center of the rear side of the screening cylinder, and several material feeding plates fixedly connected to the surface of the output shaft of the first motor located inside the screening cylinder.

[0005] Furthermore, the circulating screening assembly includes a circulating screening shell, which is fixedly connected to and communicates with the right surface of the screening cylinder. Several cleaning rollers are rotatably connected inside the circulating screening shell, and a second screening screen inclined toward the reflux assembly is also installed on the inner wall of the circulating screening shell.

[0006] Furthermore, the reflux assembly includes a reflux cylinder, which is fixedly installed on the outside of the circulating screening shell via a connecting block. The reflux cylinder is interconnected with the circulating screening shell via a reflux pipe. A second motor is fixedly installed at the top of the reflux cylinder. Several feeding augers are installed on the surface of the output shaft of the second motor located inside the reflux cylinder. A discharge pipe is fixedly connected to the outer surface of the reflux cylinder at a position corresponding to the feed hopper and is interconnected with it.

[0007] Furthermore, a discharge port is provided on the front side of the screening cylinder, and a sealing baffle is hinged to the front side of the screening cylinder at the position corresponding to the discharge port.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention uses a feeding hopper to add the Chinese medicinal herbs to be screened into a screening cylinder. After the first motor is turned on, its output shaft drives multiple guide plates to rotate, moving the herbs. When the herbs pass through the first screening screen, some impurities and dust are filtered out. As the guide plates continue to rotate counter-clockwise, some herbs enter the circulating screening shell through the opening on the screening cylinder. First, a cleaning roller removes some dust adhering to the surface of the herbs, then the herbs pass through a second screening screen for further screening of dust and impurities. Impurities fall to the bottom, and the herbs pass through... The inclined second screening mesh falls onto the return pipe and enters the return cylinder. A second motor drives multiple feeding augers to rotate, conveying the Chinese herbal medicine slices upwards to the discharge pipe. The slices then re-enter the screening cylinder through the feed hopper. This cycle repeats, achieving the cyclical screening of the Chinese herbal medicine slices. This screening device for processing Chinese herbal medicine slices has a reasonable structural design and is easy to use. By employing a cyclical screening method, it can effectively remove dust adhering to the surface of the Chinese herbal medicine slices and impurities mixed inside, thereby maximizing the efficiency and effectiveness of screening, ensuring product quality, and making it highly practical.

Detailed Implementation

[0012] 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.

[0013] Please see Figure 1-5 A screening device for processing Chinese herbal medicine slices includes a support 1, a screening cylinder 2 mounted on the support end of the support 1, the screening cylinder 2 being a cylindrical structure, a first screening screen 3 mounted on the lower surface of the screening cylinder 2, a circulating screening component 4 fixedly connected to and communicating with the right surface of the screening cylinder 2, a return component 5 fixedly connected to the circulating screening component 4, a feed hopper 6 fixedly connected to and communicating with the rear side of the screening cylinder 2, a first motor 7 fixedly mounted at the center of the rear side of the screening cylinder 2, and several material-pulling plates 8 fixedly connected to the surface of the output shaft of the first motor 7 located inside the screening cylinder 2. The output shaft of the first motor 7 drives the multiple material-pulling plates 8 to rotate counterclockwise, thus moving the position of the Chinese herbal medicine slices. When passing through the first screening screen 3, some impurities and dust can be screened out. When the material-pulling plates 8 drive the Chinese herbal medicine slices to rotate counterclockwise continuously, when passing through the circulating screening component 4, some medicine will enter the interior of the screening cylinder 2 through the opening.

[0014] The circulating screening component 4 includes a circulating screening shell 41, which is fixedly connected to and communicates with the right surface of the screening cylinder 2. Several cleaning rollers 42 are rotatably connected inside the circulating screening shell 41. The Chinese herbal medicine pieces falling into the circulating screening shell 41 first pass through the cleaning rollers 42, which can provide a certain degree of adhesion and cleaning effect on the dust adhering to the surface. A second screening screen 43 inclined towards the reflux component 5 is also installed on the inner wall of the circulating screening shell 41. The dust and impurities are further screened by the second screening screen 43, and the impurities fall below the second screening screen 43.

[0015] The reflux assembly 5 includes a reflux cylinder 51, which is fixedly installed on the outside of the circulating screening shell 41 via a connecting block. The reflux cylinder 51 is interconnected with the circulating screening shell 41 via a reflux pipe 52. The connection end of the reflux pipe 52 and the circulating screening shell 41 should be located above the second screening screen 43, so that the Chinese herbal medicine pieces above the second screening screen 43 can be guided into the reflux cylinder 51. A second motor 53 is fixedly installed at the top of the reflux cylinder 51. Several feeding augers 54 are installed on the output shaft surface of the second motor 53 located inside the reflux cylinder 51. A discharge pipe 55 is fixedly connected to the outer surface of the reflux cylinder 51 at the position corresponding to the feed hopper 6, and is interconnected with it. The second motor 53 drives the multiple feeding augers 54 to rotate, conveying the Chinese herbal medicine pieces upward to the discharge pipe 55 for discharge, and then re-entering into the screening cylinder 2 through the feed hopper 6 to achieve circulating screening.

[0016] The front side of the screening cylinder 2 has a discharge port, which is obscured in the diagram and not shown. A sealing baffle 9 is hinged to the front side of the screening cylinder 2 corresponding to the discharge port. The front side of the sealing baffle 9 has a handle. The sealing baffle 9 can prevent the material from flowing out during the screening of Chinese herbal medicine pieces and can also prevent the dust and debris generated from drifting to the outside. After screening, the sealing baffle 9 can be opened and the screened Chinese herbal medicine pieces can be taken out from the discharge port. The support base 1 has four legs. The screening cylinder 2 can be hinged to the four legs of the support base 1. The rear two legs can be raised and lowered, so that the rear end of the screening cylinder 2 can be raised to facilitate the sliding out of the Chinese herbal medicine pieces. Alternatively, an electric push rod can be installed on the back of the screening cylinder 2, and a push plate can be installed on the telescopic end of the electric push rod. The push plate can be used to push out the screened Chinese herbal medicine pieces. The above two methods of taking out material from the cylindrical cylinder are mature existing technologies and will not be described in detail here.

[0017] A bracket 10 is fixedly connected to the surface of the screening cylinder 2 and to both sides corresponding to the first screening screen 3. A strip 11 is inserted into the inside of the bracket 10. The two strips 11 are fixedly connected to each other through a collection box 12. The collection box 12 can be installed by inserting the strips 11 and the bracket 10. The impurities and dust screened out can be collected from below the first screening screen 3. A pull handle is installed on the collection box 12 so that it can be easily pulled out for cleaning.

[0018] The front side of the circulating screening shell 41 has a discharge port, which is obscured in the diagram and not shown. A sealing door 44 is hinged to the front side of the circulating screening shell 41 at the position corresponding to the discharge port. Opening the sealing door 44 allows for the removal of dust and impurities deposited below the second screening screen 43. This screening device for processing Chinese herbal medicine slices has a reasonable structural design and is easy to use. Employing a circulating screening method, it can effectively remove dust adhering to the surface of Chinese herbal medicine slices and impurities mixed within them, thereby maximizing screening efficiency and effectiveness, ensuring product quality, and making it highly practical.

[0019] In use, the Chinese herbal medicine slices to be screened are added into the screening cylinder 2 through the feed hopper 6. After the first motor 7 is turned on, its output shaft drives multiple material guide plates 8 to rotate and move the position of the Chinese herbal medicine slices. When passing through the first screening screen 3, some impurities and dust can be screened out. When the material guide plates 8 drive the Chinese herbal medicine slices to rotate counterclockwise, when passing through the circulating screening component 4, some medicine will enter the circulating screening shell 41 through the opening on the screening cylinder 2. First, the cleaning roller 42 is used to clean the dust adhering to the surface of the Chinese herbal medicine slices. Then, the dust and impurities are further screened through the second screening screen 43. The impurities fall to the bottom, and the Chinese herbal medicine slices fall into the return pipe 52 through the inclined second screening screen 43 and enter the return cylinder 51. The second motor 53 drives multiple feeding augers 54 to rotate and transport the Chinese herbal medicine slices upward to the discharge pipe 55 for discharge. Then, they re-enter the screening cylinder 2 through the feed hopper 6. This cycle is repeated to achieve the circulating screening of Chinese herbal medicine slices.

[0020] 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.
