Description

Technical Field

[0001] This utility model relates to the field of medicinal material production technology, specifically a novel medicinal material dust removal machine. Background Technology

[0002] In order to remove impurities such as mud, sand, debris, and insect eggs during the production of medicinal materials and to make them conform to pharmacopoeia or industry standards, existing dust removal methods generally include vibration dust removal, airflow sorting dust removal, and spray washing. Vibration dust removal usually relies on vibrating screens to separate medicinal materials from impurities. However, the medicinal materials need to be vibrated during the vibration dust removal process. For more brittle medicinal materials, this can easily lead to breakage or pulverization, affecting the grade and selling price of the medicinal materials. Utility Model Content

[0003] To address the above problems, the purpose of this utility model is to provide a new type of medicinal herb dust removal machine. This solves the problem that while vibration dust removal usually relies on vibrating screens to separate medicinal herbs from impurities, the herbs need to vibrate during the process. For brittle herbs, this can easily lead to breakage or pulverization, affecting the grade and selling price of the herbs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a novel medicinal material dust collector, comprising a dust collection chamber and a vibrating screen. A drive motor is installed on the outside of the dust collection chamber, and a transmission roller is connected to the output end of the drive motor. A mesh conveyor belt is installed on the outside of the transmission roller. A feed inlet is installed at the top of the dust collection chamber, and a discharge outlet is installed at the bottom of the dust collection chamber. A filter chamber is installed at the bottom of the dust collection chamber, and an exhaust fan is connected to the outside of the filter chamber via a pipe. A diversion pipe is connected to the outside of the exhaust fan, and a dust collection chamber is connected to the inside of the diversion pipe. A mesh plate is installed above the dust collection chamber. An air jet device is installed inside the dust collection chamber near the top of the mesh conveyor belt. The vibrating screen is installed inside the dust collection chamber, and a vibrating motor is connected to the outside of the vibrating screen. A guide rod is welded to the bottom of the vibrating screen, and a helical spring is sleeved on the outside of the guide rod. A ash discharge port is opened at the bottom of the vibrating screen. An ash collection chamber is inserted and installed in the dust collection chamber near the bottom of the vibrating screen.

[0005] The beneficial effects of this utility model are as follows: During the dust removal process, the dust on the medicinal materials is collected into the filter chamber by the mesh conveyor belt, air nozzle and dust collection bin. This can effectively reduce the phenomenon of medicinal materials breaking or crushing due to dust removal. In addition, the vibrating screen set in the middle of the mesh conveyor belt can turn the medicinal materials over. And because the vibrating screen is set at an inclination, the medicinal materials can pass through the vibrating screen quickly, which can further protect the medicinal materials.

[0006] To facilitate the transportation of medicinal materials:

[0007] As a further improvement to the above technical solution: the number of mesh conveyor belts is two, and the mesh conveyor belts and the dust removal chamber are arranged in parallel to each other.

[0008] The beneficial effect of this improvement is that the two mesh conveyor belts can transport the medicinal materials under the drive of the drive motor and the transmission roller.

[0009] To facilitate vibration dust removal:

[0010] As a further improvement to the above technical solution: the helical springs are arranged symmetrically about the center line of the vibrating screen.

[0011] As a further improvement to the above technical solution: the helical spring and the guide rod are arranged with their axes coincident.

[0012] The beneficial effects of this improvement are as follows: the vibrating motor drives the vibrating screen to vibrate, the guide rod cooperates with the helical spring to assist the vibrating screen to vibrate, and the coincident setting of the axis can ensure the efficiency and effect of the helical spring-assisted vibration.

[0013] For easier dust removal:

[0014] As a further improvement to the above technical solution: the jet device includes a blower, which is installed at the bottom of the dust removal chamber, and a second diversion pipe is connected to the outside of the blower. Air supply pipes are arranged at equal intervals on the inner side of the second diversion pipe, and jet nozzles are installed at equal intervals below the air supply pipes.

[0015] The beneficial effects of this improvement are as follows: the blower delivers gas through the two-way gas delivery pipe through the diversion pipe, and the gas is blown towards the medicinal materials through the jet nozzle, blowing the floating dust on the medicinal materials into the dust collection bin. The gas delivery pipes and jet nozzles installed at equal intervals can ensure the efficiency and effectiveness of dust removal.

[0016] As a further improvement to the above technical solution: the gas transmission pipeline and the dust removal chamber are arranged in parallel to each other.

[0017] The beneficial effects of this improvement are: the parallel arrangement of the gas pipelines allows the gas delivery pipes to work with the nozzles to blow the gas evenly onto the medicinal materials, thereby blowing off the floating dust on the medicinal materials.

[0018] To facilitate dust collection:

[0019] As a further improvement to the above technical solution: the bottom of the inner side of the dust collection bin is inclined.

[0020] The beneficial effect of this improvement is that the inclined dust collection bin makes it easier for dust to be transported to the interior of the filter chamber by the diversion pipe and the exhaust fan.

[0021] To facilitate the transportation of medicinal materials:

[0022] As a further improvement to the above technical solution: a slide gate valve is installed at the bottom of the discharge port.

[0023] The beneficial effect of this improvement is that the slide gate valve can easily open and close the discharge port. Attached Figure Description

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0031] like Figure 1-5As shown, a novel medicinal herb dust collector includes a dust collection chamber 1 and a vibrating screen 4. A drive motor 15 is installed on the outside of the dust collection chamber 1, and the output end of the drive motor 15 is connected to a transmission roller 11. A mesh conveyor belt 12 is installed on the outside of the transmission roller 11. A feed inlet 13 is installed at the top of the dust collection chamber 1, and a discharge outlet 14 is installed at the bottom of the dust collection chamber 1. A filter chamber 2 is installed at the bottom of the dust collection chamber 1, and an exhaust fan 21 is connected to the outside of the filter chamber 2 via a pipe. A diversion pipe 22 is connected to the outside of the exhaust fan 21, and a dust collection chamber 23 is connected to the inside of the diversion pipe 22. A mesh plate 24 is installed above the dust collection chamber 23. A screen 24 is installed inside the dust collection chamber 1 near the top of the mesh conveyor belt 12. The vibrating screen 4 is installed inside the dust collection chamber 1 and equipped with an air jet device. A vibrating motor 41 is connected to the outside of the vibrating screen 4. A guide rod 42 is welded to the bottom of the vibrating screen 4, and a helical spring 43 is sleeved on the outside of the guide rod 42. A ash discharge port 44 is opened at the bottom of the vibrating screen 4. A dust collection chamber 45 is inserted and installed in the dust collection chamber 1 near the bottom of the vibrating screen 4. During the dust removal process, the dust on the medicinal materials is collected into the filter chamber 2 by the mesh conveyor belt 12, air jet nozzle 33, and dust collection bin 23. This effectively reduces the breakage or pulverization of medicinal materials caused by dust removal. Furthermore, the vibrating screen 4, located in the middle of the mesh conveyor belt 12, can tumble the medicinal materials, and because the vibrating screen 4 is tilted, it can... The medicinal materials are quickly passed through the vibrating screen 4, which further protects them. Two mesh conveyor belts 12 are arranged parallel to each other in the dust collection chamber 1. The two mesh conveyor belts 12 transport the medicinal materials under the drive of the drive motor 15 and the transmission roller 11. The spiral springs 43 are symmetrically arranged about the center line of the vibrating screen 4, and their axes coincide with those of the guide rod 42. The vibrating motor 41 drives the vibrating screen 4 to vibrate, and the guide rod 42 assists the vibration of the vibrating screen 4 in conjunction with the spiral springs 43. The coincident arrangement of the axes ensures the efficiency and effectiveness of the spiral springs 43 in assisting the vibration. The air jet device includes a blower 3, which is installed at the bottom of the dust collection chamber 1. A second diversion pipe 31 is connected to the outer side of the blower 3. Air supply pipes 32 are evenly spaced along the inner side of the second diversion pipe 31, and nozzles 33 are evenly spaced below the air supply pipes 32. The blower 3 supplies gas to the air supply pipes 32 through the second diversion pipe 31. The gas is blown onto the medicinal materials through the nozzles 33, blowing the floating dust off the materials into the dust collection chamber 23. The evenly spaced air supply pipes 32 and nozzles 33 ensure efficient and effective dust removal. The air supply pipes 32 and the dust collection chamber 1 are arranged parallel to each other. This parallel arrangement allows the air supply pipes 32, in conjunction with the nozzles 33, to evenly blow gas onto the medicinal materials, thereby blowing off the floating dust. The bottom inner side of the dust collection chamber 23 is inclined.The inclined dust collection chamber 23 allows dust to be more easily transported to the interior of the filter chamber 2 via the diversion pipe 22 and the exhaust fan 21. A slide valve is installed at the bottom of the discharge port 14, facilitating the opening and closing of the discharge port 14.

[0032] The working principle of this utility model is as follows: When using this device, the medicinal materials enter the dust removal chamber 1 through the feed inlet 13 and fall onto the first layer of mesh conveyor belt 12. The drive motor 15 drives the mesh conveyor belt 12 to transport the medicinal materials through the transmission roller 11. During the transport process, the blower 3 delivers gas to the gas supply pipe 32 through the second diversion pipe 31. The gas is blown onto the medicinal materials through the nozzle 33, blowing the floating dust on the medicinal materials into the dust collection bin 23. The exhaust fan 21 collects the dust collected in the dust collection bin 23 into the filter bin 2 through the first diversion pipe 22. The medicinal materials continue to be transported by the mesh conveyor belt 12 and reach the vibrating screen 4. Above, the vibrating motor 41 drives the vibrating screen 4 to vibrate. The guide rod 42, together with the spiral spring 43, assists the vibrating screen 4 in vibrating. The dust generated during the vibration enters the dust collection chamber 45 through the dust discharge port 44. The vibrated medicinal materials fall above the second layer of mesh conveyor belt 12. The drive motor 15 drives the mesh conveyor belt 12 to run. After the medicinal materials are vibrated by the vibrating screen 4, they are turned over. The air nozzle 33 blows the dust off the medicinal materials. The dust collection bin 23, together with the filter bin 2, collects the dust. After the medicinal materials are dusted, they enter the discharge port 14. Opening the slide valve at the bottom of the discharge port 14 can remove the dusted medicinal materials.
