Technical Field

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

[0002] During the processing of Chinese medicinal herbs into medicinal slices, impurities such as dust, soil, and plant debris may be mixed in. Air separation can use wind power to separate these lighter impurities, thereby improving the purity of the medicinal slices. Therefore, an air separation device is required.

[0003] A Chinese patent with authorization announcement number CN213967718U discloses an automatic air-separation device for Chinese herbal medicine slices, including a machine body. A mounting frame is fixed on one side of the machine body. Two guide blocks are symmetrically installed on both sides of the inner wall of the machine body. An installation groove is opened at the bottom of the machine body, and a removable collection box is inserted into the installation groove. A detachable first waste box and a second waste box are inserted into one side of the bottom of the machine body through a support plate. This utility model can disperse Chinese herbal medicine slices, so that the Chinese herbal medicine slices fall evenly into the interior of the machine body, thereby achieving uniform air separation of Chinese herbal medicine slices and improving the air separation effect of Chinese herbal medicine slices.

[0004] However, the aforementioned air separation device still has some problems. During the air separation process, dust and impurities gradually accumulate on the filter screen, clogging the mesh and reducing airflow, which leads to a decrease in force and reduced airflow in the air separation box. This makes it impossible to effectively separate the light impurities in the Chinese herbal medicine pieces, thus greatly reducing the air separation efficiency. Therefore, an air separation device for Chinese herbal medicine pieces is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a wind-sorting device for Chinese herbal medicine slices.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A traditional Chinese medicine decoction piece air separation device of this utility model includes an air separation box, a support block installed at the top edge of the air separation box, a collection box installed on the top side of the support block, a negative pressure motor installed on one side of the collection box, a rotating shaft installed at the output end of the negative pressure motor, five fan blades installed on the outer side of the middle end of the rotating shaft, an exhaust port opened on one side of the collection box, an eccentric wheel installed at one end of the rotating shaft, a connecting block installed at the top edge of the collection box, and a connecting block and a support block each having an air separation device installed on one side of the supporting block. The system is equipped with a connecting rod, on the outer side of which a filter screen is slidably mounted. Three top rods are equidistantly mounted on one side of the filter screen. The eccentric wheel contacts the top rods during operation. Tension springs are fixed to both ends of the filter screen, the connecting block, and the support block, respectively. The tension springs are respectively sleeved on the outer wall of the connecting rod. Sliding grooves are opened on both sides of the collection box, and the filter screen is slidably installed inside the sliding grooves. A dust suction pipe is connected to the other side of the collection box, which effectively reduces the accumulation of dust or impurities on the filter screen, ensures the smooth operation of the air separation process, and thus improves the air separation efficiency.

[0007] Preferably, the air separator has three grooves on each of its two sides, and guide rods are fixedly connected between the two sides of each groove. Mounting blocks are slidably mounted on each guide rod, and compression springs are fixedly connected between the mounting blocks and the top of the grooves. The compression springs are sleeved on the outer wall of the guide rods. A holding box is mounted between the mounting blocks. Two through holes are opened on the top side of the holding box, with one end of a suction pipe extending through the air separator into the through holes. A feed pipe is connected to the top side of the air separator, with one end movably mounted inside the through holes. Inclined plates are provided on both sides of the holding box, increasing the contact area between the medicinal herbs and the airflow, promoting collisions between the herbs, improving the air separator effect, and removing more impurities.

[0008] Preferably, the bottom side of the holding box has a discharge port, and the bottom side of the holding box has a through groove located at the discharge port. A baffle is slidably installed inside the through groove, and a side plate is installed on one side of the baffle. Locking screws are rotatably installed inside both ends of the side plate. A receiving box is installed on the bottom inner wall of the air classifier directly below the discharge port, so that the Chinese herbal medicine pieces can be conveniently and quickly discharged into the receiving box after air classification.

[0009] Preferably, a drive motor is installed on one side of the air separator, and a rotating shaft is installed at the output end of the drive motor. Cams are installed at both ends of the rotating shaft. When the cams are in operation, they will contact the bottom side of the container, so that the container can vibrate up and down during the air separation process.

[0010] Preferably, a hinged door is installed on one side of the air separator, and a handle is installed on one side of the door to facilitate opening the door for cleaning or material removal inside.

[0011] Preferably, a control panel is installed on one side of the air separator box. The control panel is used to operate and control the internal electrical components of the device, thereby realizing centralized control of the internal electrical components of the device.

[0012] The advantages of this utility model are:

[0013] 1. This utility model starts a negative pressure motor, which drives the rotating shaft to rotate. The eccentric wheel rotates accordingly. When the eccentric wheel contacts the top rod, it pushes the filter screen to slide along the slide groove, causing the tension spring to be stretched. When the eccentric wheel rotates away from the top rod, the tension spring rebounds, pulling the filter screen to slide in the opposite direction, causing the filter screen to vibrate continuously. This effectively reduces the accumulation of dust or impurities on the filter screen, ensures the smooth operation of the air separation process, and thus improves the air separation efficiency.

[0014] 2. The present invention starts the drive motor, which drives the rotating shaft and cam to rotate. When the protruding part of the cam contacts the holding box, it pushes the holding box upward. At this time, the mounting block slides upward along the guide rod and compresses the compression spring. When the protruding part of the cam rotates away from the bottom side of the holding box, the compression spring rebounds, the mounting block slides downward, and the holding box moves downward. This increases the contact area between the Chinese herbal medicine slices and the airflow, promotes the collision between the slices, and makes it easier for lighter impurities to be carried away by the airflow, thus improving the air separation effect.

[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 scope of protection of the present utility model.

[0023] Please see Figure 1-5 As shown, a traditional Chinese medicine decoction piece air separation device includes an air separation box 1, a support block 2 installed at the top edge of the air separation box 1, a collection box 3 installed on the top side of the support block 2, a negative pressure motor 4 installed on one side of the collection box 3, a rotating shaft 5 installed at the output end of the negative pressure motor 4, five fan blades 6 installed on the outer side of the middle end of the rotating shaft 5, an exhaust port 7 opened on one side of the collection box 3, an eccentric wheel 8 installed at one end of the rotating shaft 5, and a connecting block 10 installed at the top edge of the collection box 3. The connecting block 10 is connected to one side of the support block 2. Each is equipped with a connecting rod 11, and a filter screen 12 is slidably mounted on the outer side of the connecting rod 11. Three top rods 9 are equidistantly mounted on one side of the filter screen 12. The eccentric wheel 8 contacts the top rods 9 during operation. Tension springs 13 are fixedly connected to both ends of the filter screen 12, the connecting block 10, and the support block 2, respectively. The tension springs 13 are respectively sleeved on the outer wall of the connecting rod 11. Sliding grooves 14 are opened on both sides of the collection box 3. The filter screen 12 is slidably installed inside the sliding grooves 14. A dust suction pipe 15 is connected to the other side of the collection box 3.

[0024] A control panel 33 is installed on one side of the air separator 1. During operation, dust and impurities gradually accumulate on the filter screen 12, clogging the mesh and reducing airflow. This weakens the airflow, making it difficult to effectively separate light impurities from the Chinese herbal medicine slices, thus significantly reducing airflow efficiency. The negative pressure motor 4 is activated, driving the rotating shaft 5 to rotate, causing the fan blades 6 to rotate. This creates negative pressure in the collection box 3, drawing air from the holding box 20, carrying dust and impurities, into the collection box 3. Simultaneously, the rotating shaft 5 rotates... The eccentric wheel 8 also rotates. When the eccentric wheel 8 contacts the top rod 9, it pushes the filter screen 12 to slide along the connecting rod 11 and the slide groove 14, causing the tension spring 13 to be stretched. When the eccentric wheel 8 rotates away from the top rod 9, the tension spring 13 rebounds, pulling the filter screen 12 to slide in the opposite direction. This process is repeated, causing the filter screen 12 to vibrate continuously, thereby effectively reducing the accumulation of dust or impurities on the filter screen 12. The dust and impurities are blocked on one side of the filter screen 12, and the filtered air is discharged from the exhaust port 7, ensuring the smooth operation of the air separation process and thus improving the air separation efficiency.

[0025] Please see Figure 1-5 As shown, three grooves 16 are provided inside both sides of the air separator 1. Guide rods 17 are fixed between the two sides of each groove 16. Mounting blocks 18 are slidably installed on each guide rod 17. Compression springs 19 are fixed between the mounting blocks 18 and the top side of the grooves 16. The compression springs 19 are sleeved on the outer wall of the guide rods 17. A holding box 20 is installed between the mounting blocks 18. Two through holes are provided on the top side of the holding box 20. One end of the dust suction pipe 15 extends through the air separator 1 into the through hole. A feed pipe 21 is connected to the top side of the air separator 1. One end of the feed pipe 21 is movably installed inside the through hole. Inclined plates 22 are provided on both sides of the holding box 20. A drive motor 28 is installed on one side of the air separator 1. A rotating shaft 29 is installed at the output end of the drive motor 28. Cams 30 are installed at both ends of the rotating shaft 29. The cams 30 will contact the bottom side of the holding box 20 during operation.

[0026] The bottom side of the holding box 20 has an outlet 23. The bottom side of the holding box 20 has a through groove at the outlet 23. A baffle 24 is slidably installed inside the through groove. A side plate 25 is installed on one side of the baffle 24. Locking screws 26 are rotatably installed inside both ends of the side plate 25. A receiving box 27 is installed on the bottom inner wall of the air classifier box 1 directly below the outlet 23.

[0027] A hinged door 31 is installed on one side of the air-separating box 1, and a handle 32 is installed on one side of the door 31. During operation, in the process of processing Chinese medicinal materials into decoction pieces, impurities such as dust, soil, and plant debris will be mixed in. Air separation can use wind power to separate these lighter impurities, thereby improving the purity of the decoction pieces. During air separation, the Chinese medicinal materials to be processed are placed into the holding box 20 through the feed pipe 21. The drive motor 28 is started, which drives the rotating shaft 29 and the cam 30 to rotate. When the protruding part of the cam 30 contacts the bottom side of the holding box 20, The upward movement of the cam 30 pushes the container 20 upward. At this time, the mounting block 18 slides upward along the guide rod 17 in the groove 16 and compresses the compression spring 19. When the protruding part of the cam 30 turns away from the bottom side of the container 20, the compression spring 19 rebounds, pushing the mounting block 18 downward, which in turn drives the container 20 to move downward. This allows the container 20 to vibrate up and down during the air separation process, increasing the contact area between the Chinese herbal medicine slices and the airflow, promoting the collision between the slices, making it easier for lighter impurities to be carried away by the airflow, improving the air separation effect, and removing more impurities.

[0028] After the air separation is completed, rotate to loosen the locking screw 26, pull the side plate 25, and drive the baffle 24 to slide in the through groove on the bottom side of the holding box 20, opening the discharge port 23. The air-separated Chinese herbal medicine pieces fall from the discharge port 23 into the receiving box 27, so that the Chinese herbal medicine pieces can be conveniently and quickly discharged into the receiving box 27 after the air separation is completed. When it is necessary to clean or remove materials from the inside of the air separation box 1, hold the handle 32 and open the movable door 31.

[0029] Working principle: Starting the negative pressure motor 4 drives the rotating shaft 5 to rotate, causing the fan blades 6 to rotate. This creates negative pressure in the collection box 3, causing the air in the holding box 20, carrying dust and impurities, to be sucked into the collection box 3. As the rotating shaft 5 rotates, the eccentric wheel 8 also rotates. When the eccentric wheel 8 contacts the top rod 9, it pushes the filter screen 12 to slide along the connecting rod 11 and the slide groove 14, causing the tension spring 13 to be stretched. When the eccentric wheel 8 rotates away from the top rod 9, the tension spring 13 rebounds, pulling the filter screen 12 to slide in the opposite direction. This process repeats, causing the filter screen 12 to vibrate continuously, thereby effectively reducing the accumulation of dust or impurities on the filter screen 12. The dust and impurities are blocked on one side of the filter screen 12, and the filtered air is discharged from the exhaust port 7, ensuring the smooth operation of the air separation process and thus improving the air separation efficiency.

[0030] The Chinese herbal medicine slices to be processed are placed into the holding box 20 through the feed pipe 21. The drive motor 28 is started, which drives the rotating shaft 29 and cam 30 to rotate. When the protruding part of cam 30 contacts the bottom side of the holding box 20, it will push the holding box 20 upward. At this time, the mounting block 18 slides upward along the guide rod 17 in the groove 16 and compresses the compression spring 19. When the protruding part of cam 30 rotates away from the bottom side of the holding box 20, the compression spring 19 rebounds and pushes the mounting block 18 to slide downward, thereby driving the holding box 20 to move downward. This allows the holding box 20 to vibrate up and down during the air separation process, which increases the contact area between the Chinese herbal medicine slices and the airflow, promotes the collision between the slices, and makes it easier for lighter impurities to be carried away by the airflow, thus improving the air separation effect and removing more impurities.

[0031] After the air separation is completed, rotate to loosen the locking screw 26, pull the side plate 25, and drive the baffle 24 to slide in the through groove on the bottom side of the holding box 20, opening the discharge port 23. The air-separated Chinese herbal medicine pieces fall from the discharge port 23 into the receiving box 27, so that the Chinese herbal medicine pieces can be conveniently and quickly discharged into the receiving box 27 after the air separation is completed. When it is necessary to clean or remove materials from the inside of the air separation box 1, hold the handle 32 and open the movable door 31.
