A dust removal device for Chinese medicinal herbs

Abstract

This utility model relates to a dust removal device for Chinese medicinal herbs, effectively solving the problems of filter clogging and dust not easily dispersing. The technical solution includes a horizontal outer cylinder with an air inlet pipe at the bottom and an air outlet pipe at the top. A first fan is installed in the air inlet pipe, and a second fan is installed in the air outlet pipe. The first fan blows air into the outer cylinder, and the second fan draws air outward. A sieve cylinder is coaxially mounted inside the outer cylinder and can rotate within it. Several inclined plates, higher on the left and lower on the right, are evenly distributed along the axis of the sieve cylinder. As the sieve cylinder rotates continuously, the first fan can blow away the medicinal herbs adhering to the inner wall of the sieve cylinder, preventing the herbs from clogging the sieve cylinder and maintaining its permeability, allowing dust to be smoothly discharged with the airflow. The sieve cylinder's tumbling of the herbs and the impact of the herbs with the inclined plates further disperse the herbs and shake off the dust, improving the dust removal effect.

Description

Technical Field

[0001] This utility model relates to the field of medicinal material processing, specifically a dust removal device for Chinese medicinal materials. Background Technology

[0002] To ensure the purity of medicinal materials, they are generally dusted before use. Utility model patent application number CN201620424137.4 discloses a dust removal device for medicinal materials. It has an air outlet and filter screen at the top of the separation chamber and a blower at the bottom. The dust in the medicinal materials is removed by the upward airflow. This structure is common in current dust removal equipment. It has two main drawbacks: first, medicinal material debris easily accumulates on the filter screen, clogging it and reducing airflow, thus affecting the dust removal effect; second, the dust is not easily dispersed because the medicinal materials accumulate at the bottom. Summary of the Invention

[0003] This utility model provides a dust removal device for Chinese medicinal materials, which aims to solve the problems of filter clogging and dust not being easily dispersed.

[0004] The technical solution includes a horizontal outer cylinder with an air inlet pipe at the bottom and an air outlet pipe at the top. A first fan is installed in the air inlet pipe, and a second fan is installed in the air outlet pipe. The first fan blows air into the outer cylinder, and the second fan draws air out. A sieve cylinder is coaxially installed inside the outer cylinder and can rotate within it. Several inclined plates, which are higher on the left and lower on the right, are evenly distributed along the axis of the sieve cylinder.

[0005] The sieve cylinder consists of cylindrical sections at both ends and a screen section connecting the two cylindrical sections. Each end of the outer cylinder is evenly distributed with several support wheels. The support wheels contact the outer wall of the cylindrical section to support the sieve cylinder.

[0006] The cylindrical section has an annular groove, and the support wheel is located inside the annular groove.

[0007] One of the cylindrical sections has a gear ring coaxially mounted on its outer wall. The gear ring meshes with a drive gear, which is connected to a drive motor.

[0008] The screen section has several axial plates evenly distributed around its inner circumference, and the two ends of the axial plates are respectively fixed to the cylindrical section at the same end.

[0009] It also includes two support frames, which are used to fix and support the outer cylinder.

[0010] A fixed shaft is provided at the axis of the screen cylinder, and all the inclined plates are fixed on the fixed shaft. The two ends of the fixed shaft are fixed to the support frame via connecting plates.

[0011] In this invention, as the sieve cylinder rotates continuously, the first fan can blow away the medicinal materials adhering to the inner wall of the sieve cylinder, preventing the medicinal materials from clogging the sieve cylinder and keeping the sieve cylinder permeable, allowing dust to be smoothly discharged with the airflow.

[0012] This invention improves dust removal efficiency by using a sieve cylinder to tumble the medicinal materials and by having the materials collide with an inclined plate to further disperse the materials and shake off the dust. Attached Figure Description

[0019] Referring to the accompanying drawings, this utility model includes a horizontal outer cylinder 1, with an air inlet pipe 2 at the bottom and an air outlet pipe 3 at the top. A first fan 4 is installed inside the air inlet pipe 2, and a second fan 5 is installed inside the air outlet pipe 3. The first fan 4 blows air into the outer cylinder 1, and the second fan 5 draws air outwards. A sieve cylinder 6 is coaxially mounted inside the outer cylinder 1 and can rotate within it. The medicinal materials to be dusted are fed into the sieve cylinder 6 from its left end and agitated within it. The airflow enters the outer cylinder through the air inlet pipe 2. 1. The medicine passes through the sieve cylinder 6 from bottom to top and then exits from the air outlet pipe 3 into the outer cylinder 1. The dust in the medicine is discharged with the airflow. Inside the sieve cylinder 6, there are several inclined plates 7 that are higher on the left and lower on the right. The inclined plates 7 are evenly distributed along the axis of the sieve cylinder 6. The medicine is turned up by the sieve cylinder 6 and then falls onto the inclined plates 7. It slides down to the right side along the inclined plates 7, so that the medicine is gradually fed into the right end of the sieve cylinder 6 until it is discharged from the right end of the sieve cylinder 6. At the same time, the collision between the medicine and the inclined plates 7 helps to disperse the medicine and shake off the dust, so that the dust can be dispersed.

[0020] The sieve cylinder 6 is composed of cylindrical sections 8 at both ends and a screen section 9 connecting the two cylindrical sections 8. Each end of the outer cylinder 1 is circumferentially distributed with several support wheels 10. The support wheels 10 contact the outer wall of the cylindrical section 8 to support the sieve cylinder 6, so that the sieve cylinder 6 and the outer cylinder 1 remain coaxial and can rotate relative to the outer cylinder 1.

[0021] The cylindrical section 8 has an annular groove 11, and the support wheel 10 is located in the annular groove 11. The annular groove 11 axially limits the screen cylinder 6, preventing the screen cylinder 6 from sliding axially.

[0022] One of the cylindrical sections 8 has a gear ring 12 coaxially mounted on its outer wall. The gear ring 12 meshes with a drive gear 13. The drive gear 13 is connected to a drive motor 14. The drive motor 14 drives the screen cylinder 6 to rotate through the gear set.

[0023] The inner circumference of the screen section 9 is evenly distributed with several axial plates 15. The two ends of the axial plates 15 are respectively fixed on the cylindrical section 8 at the same end. When the screen cylinder 6 rotates, the axial plates 15 can lift the medicinal materials to a greater height.

[0024] It also includes two support frames 16, which are used to fix and support the outer cylinder 1.

[0025] A fixed shaft 17 is provided at the axis of the screen cylinder 6, and all the inclined plates 7 are fixed on the fixed shaft 17. The two ends of the fixed shaft 17 are fixed on the support frame 16 via connecting plates 18, thereby realizing the fixation of the inclined plates 7 inside the screen cylinder 6.

[0026] In use, the medicinal materials are fed into the sieve cylinder 6 from the left end. The drive motor 14 and two fans are started. The drive motor 14 drives the sieve cylinder 6 to rotate through the gear set. The medicinal materials are tumbled inside the sieve cylinder 6. The airflow from bottom to top formed by the two fans blows out the dust in the tumbled medicinal materials. When the medicinal materials rotate to the top with the sieve cylinder 6, they fall onto the inclined plate 7, which can further disperse the medicinal materials and shake off the dust on the medicinal materials, thus improving the dust removal effect. The scattered medicinal materials slide to the right along the inclined plate 7 and are finally discharged from the right end of the sieve cylinder 6.

[0027] In this invention, as the sieve cylinder 6 rotates continuously, the first fan 4 can blow away the medicinal materials adhering to the inner wall of the sieve cylinder 6, preventing the medicinal materials from clogging the sieve cylinder 6, and keeping the sieve cylinder 6 permeable at all times, so that dust can be smoothly discharged with the airflow.

[0028] This invention improves dust removal efficiency by using the sieve cylinder 6 to tumble the medicinal materials and the impact of the materials with the inclined plate 7 to further disperse the materials and shake off the dust.
