Description
Technical Field
[0001] The utility model relates to the technical field of traditional Chinese medicine powder processing, in particular to a traditional Chinese medicine powder rotary vibrating screen. Background Art
[0002] In the process of preparing Chinese medicinal materials, it is often necessary to make Chinese medicinal materials into powder. In the process of preparing powder, the Chinese medicinal powder needs to be screened, and the Chinese medicinal powder with particle size that meets the requirements is screened out for further processing, and the Chinese medicinal powder that does not meet the requirements is ground again.
[0003] In order to facilitate the pouring of materials, the existing Chinese medicine powder rotary vibrating screen is often open when in use. At the same time, too much material is fed into the Chinese medicine powder rotary vibrating screen at one time, which hinders the normal movement of the material on the screen surface, not only easily causing the screen to fatigue and become loose, but also greatly reducing the material processing capacity. If the feeding amount does not meet the processing capacity of the equipment, it will waste energy and reduce production capacity. Therefore, continuous and uniform feeding is required, and the feeding amount shall be based on meeting the processing requirements of the equipment.
[0004] Since the vibrating screen screens materials by vibration, the materials are easily splashed out during screening. At the same time, since continuous and uniform feeding is required, frequent closing of the feed port will affect the operation of the staff and thus affect the screening of the materials. Utility Model Content
[0005] In view of the above problems, the purpose of the utility model is to provide a rotary vibrating screen for Chinese medicine powder, which solves the problem that the rotary vibrating screen screens the material by vibration, and the material is easily vibrated and splashed out during screening. At the same time, due to the need for continuous and uniform feeding, the feed port is frequently closed, which affects the operation of the staff and thus affects the screening of the material. When the medicinal materials are subjected to rotary vibration screening, some of the medicinal materials splashed out by the vibration collide with the anti-splashing protrusions during the splashing process, and then the speed of the splashing medicinal materials is slowed down by the anti-splashing protrusions, and then the slowed-down medicinal materials fall, thereby avoiding the problem of the medicinal materials splashing out of the device during rotary vibration screening.
[0006] To achieve the above objectives, the technical solution adopted by the utility model is as follows: a Chinese medicine powder rotary vibrating screen, comprising a body component, a feed component, and a material guiding component, the body component comprising a base, the feed component comprising a feed cover, the material guiding component comprising a first clamping ring and a second clamping ring, the top of the base is connected with a rotary vibrating screen body, one end of the base is connected with a second discharge port, an end of the base away from the second discharge port is connected with the first discharge port, the top of the base is connected with a mounting base plate, the lower end of the mounting base plate is connected with a stable column, the lower end of the feed cover is connected with a mounting top plate, the end of the feed cover away from the mounting top plate is connected with a connecting pipe, the end of the connecting pipe away from the feed cover is connected with the feed port, the inner wall of the first clamping ring is connected with a guide plate, the inner side of the guide plate is provided with a guide groove, the inner wall of the feed cover is connected with a mounting protrusion, and the outer ring of the mounting protrusion is wrapped with a splash-proof protrusion.
[0007] The beneficial effects of the utility model are as follows: when the medicinal materials are subjected to rotary vibration screening, part of the medicinal materials splashed out by the vibration collide with the anti-splashing protrusions during the splashing process, and then the speed of the splashing medicinal materials is slowed down by the anti-splashing protrusions, and then the slowed-down medicinal materials fall down, thereby preventing the medicinal materials from splashing out of the device during rotary vibration screening, and the medicinal materials fall on the guide plate of the inner circle of the second clamping ring after passing through the guidance of the first clamping ring, and the medicinal materials slide on the guide plate and are transported downward in a concentrated manner through the guide groove, and at the same time, the structural setting of the guide plate can form a barrier to the splashing medicinal materials, thereby further preventing the medicinal materials from splashing out of the device during rotary vibration screening.

[0009] As a further improvement of the above technical solution: a screen is arranged on the inner side of the rotary vibrating screen body, the first discharge port is a coarse discharge port, and the second discharge port is a fine discharge port.
[0010] The beneficial effect of this improvement is: after starting the operation of the rotary vibrating screen body, the vibration motor inside the rotary vibrating screen body starts working, and the eccentric blocks with different phases at the upper and lower ends generate a composite inertial force. The generated inertial force causes the vibrating body of the screen machine to perform a compound rotary motion. The screen frame continuously reciprocates under the action of the vibration force, driving the screen to vibrate periodically, and causing the medicinal materials on the screen to perform a directional and active movement. In this process, materials smaller than the screen aperture pass through the screen aperture and fall to the lower layer, becoming screened material and being discharged from the second discharge port. Materials larger than the screen aperture are discharged from the first discharge port after continuous jumping motion, and the screening work is finally completed.
[0011] In order to improve the stability of the connection between the feed cover and the vibrating screen body:
[0012] As a further improvement of the above technical solution: the stabilizing columns are installed at equal intervals on the outer circumference of the rotary vibrating screen body, and the size of the mounting top plate matches the size of the mounting bottom plate.
[0013] The beneficial effect of this improvement is that by stabilizing the setting of the columns, a supporting force is formed for the installation base plate, thereby improving the stability of the connection between the feed hood and the rotary vibrating screen body.

[0017] In order to add medicinal materials into the main body of the vortex vibrating screen:
[0018] As a further improvement of the above technical solution: the top rotating hinge of the feed port is rotatably connected with a dust cover, and the feed port is arranged in a funnel-shaped structure.
[0019] The beneficial effects of this improvement are: through the setting of the connecting pipe, the installation connection between the feed port and the feed cover is realized, and through the setting of the feed port, an inlet for adding medicinal materials into the rotary vibrating screen body is provided.

[0022] The beneficial effect of this improvement is: when in use, the dust cover is opened, and then the medicinal materials that meet the processing capacity of the rotary vibrating screen body are added into the feed port, and the medicinal materials fall on the guide plate of the inner circle of the first clamping ring. The medicinal materials slide on the guide plate and are transported downward in a centralized manner through the guide groove. The positioning plate is set to install and fix the first clamping ring and the second clamping ring.

At the same time, the structural setting of the guide plate can block the splashing medicinal materials, thereby further preventing the medicinal materials from splashing out of the device during rotary vibration screening.
[0026] In order to slow down the speed of splashing medicinal materials through anti-splash bumps:
[0027] As a further improvement of the above technical solution: the splash-proof bump is a rubber layer with a hemispherical hollow structure, the mounting bump is a hemispherical structure, the splash-proof bump is wrapped around the outer ring of the mounting bump and connected to the inner wall of the feed cover.
[0028] The beneficial effect of this improvement is that when the medicinal materials are subjected to rotary vibration screening, part of the medicinal materials splashed out by the vibration collide with the anti-splashing protrusions during the splashing process, and then the speed of the splashing medicinal materials is slowed down by the anti-splashing protrusions, and then the slowed-down medicinal materials fall down, thereby preventing the medicinal materials from splashing out of the device during rotary vibration screening.
