Description

Technical Field

[0001] This utility model belongs to the technical field of air separation equipment, and in particular, it is an air separation device for processing Chinese herbal medicine slices. Background Technology

[0002] Traditional Chinese medicine (TCM) decoction pieces are TCM herbs that have been processed according to TCM theory and methods, and can be directly used in TCM clinical practice. During processing, TCM decoction pieces require air separation to remove impurities. Existing air separation devices for TCM decoction piece processing, while improving processing quality by installing adjustment components to ensure uniform feeding, still require multiple air separation processes (requiring repeated adjustments to fan speed to remove dust, leaves, and stones), making the process time-consuming and labor-intensive.

[0003] A search revealed Chinese patent document (authorization announcement number CN218591132U), which discloses a wind-separation device for processing Chinese herbal medicine slices. This device relates to the field of wind-separation sieving of Chinese herbal medicine slices, and includes: a wind-separation box with a feed hopper extending through its top, a discharge port located at the bottom of the feed hopper and communicating with the wind-separation box, and a material control component located on one side of the bottom of the discharge port for controlling the discharge rate. This wind-separation device for processing Chinese herbal medicine slices allows for easy adjustment of the discharge rate through the material control component, ensuring uniform discharge of Chinese herbal medicine slices and debris, preventing excessive discharge and ensuring that debris within the Chinese herbal medicine slices is effectively separated. While the patent improves the processing quality of the device to some extent, the air separation process requires multiple air separation treatments of the Chinese herbal medicine pieces (requiring multiple changes in the fan speed to remove dust, leaves, and stones), making the processing flow of the device time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to provide an air separation device for processing Chinese herbal medicine slices, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wind-separation device for processing Chinese herbal medicine slices, comprising a processing box for wind separation in processing Chinese herbal medicine slices, a feeding component installed at the top of the processing box, and an auxiliary component provided at the bottom of the processing box, a fan installed on the inclined surface of the processing box, and the air outlet of the fan passing through the processing box via an air duct and connected to an air outlet hood, a collection box connected to the side of the processing box, and a screen installed at the air outlet of the collection box, two wedge plates provided on the inner side of the collection box, and a detachable collection box installed at the bottom of the collection box, an installation frame provided on the inner side of the processing box, a filter screen embedded in the inner side of the installation frame, and a vibration motor installed at the bottom of the installation frame, and an auxiliary plate for assisting in feeding is installed on the inner side of the processing box.

[0006] Preferably, the top of the collection box is fixedly connected to the fixed end of an electric push rod, and the driving end of the electric push rod passes through the collection box and is connected to a mounting frame, and cleaning brushes are attached to both sides of the mounting frame.

[0007] Preferably, the auxiliary components include a mounting base installed at the bottom of the machining box, a lead screw installed inside the mounting base, and a drive motor installed on the side of the mounting base to provide power to the lead screw.

[0008] Preferably, two adjusting blocks are installed on the outer periphery of the lead screw, and an adjusting rod is installed at the bottom end of the adjusting blocks. The end of the adjusting rod away from the adjusting blocks is hinged to a support plate.

[0009] Preferably, the feeding assembly includes a mounting box installed at the top of the processing box, a feed hopper connected to the top of the mounting box, and two drive shafts installed inside the mounting box.

[0011] Preferably, the drive shaft is equipped with gears on its outer periphery outside the mounting box, and the two gears are meshed together.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are as follows: This air-separation device for processing Chinese herbal medicine slices benefits from the design of its fan, auxiliary components, and feeding components. The feeding component evenly feeds the Chinese herbal medicine slices into the processing chamber. Once the fan is started, the generated airflow is transported through the duct to the exhaust hood and blown in a specific direction into the processing chamber. Since there is a difference in mass between whole slices and lighter impurities such as dust and debris, the lighter impurities are blown towards the collection box connected to the side of the processing chamber by the airflow. After air separation, the Chinese herbal medicine slices fall onto the filter screen. A vibration motor is then activated to shake and screen the slices, thus separating stone impurities and transferring them to the auxiliary plate for loading and unloading. Compared to existing air separation methods, this device offers better cleaning results, reducing the number of air separation processes and making the processing flow more time-saving and labor-saving. Furthermore, the design of the auxiliary components allows for adjustments to the height of the processing chamber, facilitating unloading operations, and the feeding component design ensures even feeding, greatly increasing the device's practicality.

[0013] This air-separation device for processing Chinese herbal medicine slices can reduce the number of sorting steps for Chinese herbal medicine slices, making the processing flow of the device more time-saving and labor-saving. Attached Figure Description

[0017] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0018] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0019] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs. Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail; however, where appropriate, such techniques, methods, and equipment should be considered part of the specification. The proportions of the components in the accompanying drawings are for reference only and can be adjusted to a certain extent according to the actual use.

[0020] Examples, such as Figures 1 to 4As shown, a feeding assembly 3 is installed at the top of the processing box 1, and an auxiliary assembly 2 is installed at the bottom of the processing box 1. A fan 5 is installed on the inclined surface of the processing box 1. The air outlet of the fan 5 is fixedly connected to the outside of the processing box 1, and the air outlet of the fan 5 passes through the processing box 1 through an air duct and is connected to an air outlet hood 10. A collection box 6 is connected to the side of the processing box 1, and a screen 7 is installed at the air outlet of the collection box 6. Two air outlets are provided at both ends of the collection box 6, and the screen 7 is installed at the air outlets. The design of the screen 7 can prevent impurities from being discharged outside the device with the airflow, while ensuring air circulation inside the box and maintaining airflow balance. Two wedge plates 15 are provided on the inner side of the collection box 6. The two wedge plates 15 are fixedly connected to the inner side of the collection box 6, and the symmetrical design of the two wedge plates 15 facilitates the discharge of dust and impurities. A detachable collection box 16 is installed at the bottom of the collection box 6, and the collection box 16 is slidably connected to the collection box 6. An installation frame 8 is provided inside the box 1. The installation frame 8 is movably installed inside the processing box 1 to facilitate vibration screening with the vibration motor 9. A filter screen 4 is embedded in the inner side of the installation frame 8, and the vibration motor 9 is installed at the bottom of the installation frame 8. An auxiliary plate 11 for assisting material feeding is installed inside the processing box 1. The auxiliary plate 11 has a wedge-shaped design, and its lower end is located at the feeding port. The top of the collection box 6 is fixedly connected to the fixed end of the electric push rod 12, and the driving end of the electric push rod 12 passes through the collection box 6 and is connected to the mounting frame 13. The mounting frame 13 has a U-shaped design, and cleaning brushes 14 are glued to both sides of the mounting frame 13. After the device has been running for a period of time, the electric push rod 12 is started, and its driving end extends or retracts, driving the connected mounting frame 13 to move up and down. The cleaning brushes 14 glued to both sides of the mounting frame 13 move synchronously to wipe and clean the inner wall of the collection box 6 and the surface of the wedge plate 15.

[0021] Auxiliary component 2 includes a mounting base 21 installed at the bottom of the processing box 1, a lead screw 23 installed inside the mounting base 21, and a drive motor 22 installed on the side of the mounting base 21 to provide power to the lead screw 23. The lead screw 23 is a two-section design, and the lead screw 23 is threadedly connected to two adjusting blocks 24. The adjusting blocks 24 are hinged to the adjusting rod 25. By starting the drive motor 22, the processing box 1 can be raised to a certain height, thereby adjusting the working height of the material discharge port on the side of the processing box 1. Two adjusting blocks 24 are installed on the outer periphery of the lead screw 23, and an adjusting rod 25 is installed at the bottom of the adjusting blocks 24. The end of the adjusting rod 25 away from the adjusting blocks 24 is hinged to a support plate 26, and a rubber pad is glued to the bottom of the support plate 26.

[0022] The feeding assembly 3 includes a mounting box 31 installed at the top of the processing box 1, a feeding hopper 33 connected to the top of the mounting box 31, and two drive shafts 34 installed inside the mounting box 31. The drive shafts 34 are rotatably connected inside the mounting box 31. A stepper motor 36 that provides power to the drive shafts 34 is installed on the side of the mounting box 31, and multiple feeding plates 35 are installed on the outer periphery of the drive shafts 34. Gears 32 are installed on the outer periphery of the drive shafts 34 located outside the mounting box 31, and the two gears 32 are meshed together. After the stepper motor 36 is started, its output shaft drives one of the drive shafts 34 to rotate. Since the portions of both drive shafts 34 located outside the mounting box 31 are equipped with gears 32, and the two gears 32 mesh with each other, the two drive shafts 34 will rotate synchronously in opposite directions. The multiple feeding plates 35 on the outer periphery of the drive shafts 34 rotate with the shaft, evenly feeding the slices entering the mounting box 31, so that they fall stably into the processing box 1, effectively avoiding channel blockage caused by excessive feeding, and providing a stable material supply for subsequent processing stages.

[0023] The drive motor 22, stepper motor 36, fan 5, vibration motor 9, and electric push rod 12 are all conventional instruments. Their working principles, dimensions, and models are irrelevant to the function of this application, so they will not be described in detail. They are all controlled by remote control switches. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail. The scale of the attached drawings is for reference only and can be adjusted to a certain extent according to the actual use.

[0024] Working principle In this air-separation device for processing Chinese herbal medicine slices, the slices are fed into the mounting box 31 from the feed hopper 33. After the stepper motor 36 is started, its output shaft drives one of the drive shafts 34 to rotate. Since gears 32 are installed on the outer parts of both drive shafts 34 in the mounting box 31, and the two gears 32 mesh with each other, the two drive shafts 34 will rotate synchronously in opposite directions. Multiple feeding plates 35 on the outer periphery of the drive shafts 34 rotate with the shafts, evenly feeding the slices entering the mounting box 31 and ensuring they fall stably into the processing box 1. When the slices move to the air-separation area of ​​the processing box 1, the blower 5 starts working, and the generated airflow is transported to the air outlet hood 10 through the air duct. 10 blows air into a specific direction inside the processing box 1. Due to the difference in mass between whole medicinal slices and light impurities such as dust and debris in the medicinal slices, under the impact of the airflow, the lighter impurities will be blown towards the collection box 6 connected to the side of the processing box 1. After air separation, the medicinal slices fall onto the filter screen 4 embedded in the mounting frame 8. At this time, the vibration motor 9 starts, and its vibration force is transmitted to the mounting frame 8 and the filter screen 4, which causes the medicinal slices on the filter screen 4 to be fully dispersed. During the vibration process, small particles of impurities or debris in the medicinal slices will fall through the mesh of the filter screen 4, while larger medicinal slices that meet the particle size requirements will move along the filter screen 4 towards the air separation area under the action of vibration thrust and their own gravity.
