A kind of equipment with multilayer screening function
Technical field
The utility model relates to a kind of equipment, especially relates to a kind of equipment with multilayer screening function, is used for the screening to Chinese medicine.
Background technology
The promptly middle medical drugs of Chinese medicine is the peculiar medicine of the traditional traditional Chinese medical science of China.Chinese medicine is divided into Chinese patent drug, Chinese medicine by processing technology.Chinese medicine mainly originates from China, except autonomic drug, and animal drugs such as snake gall, bear gall, long-noded pit viper, pilose antler, deer horn etc.; Shell class such as pearl, concha meretricis seu cylinae; Mineral substance such as keel, magnetite etc. all are the Chinese medicine that is used for curing the disease.Minority Chinese medicine comes from foreign country, like American Ginseng.In the process that combats the disease, through practice, constantly understanding has accumulated abundant medicinal knowledge to China working people gradually for thousands of years.Because period in romote antiquity, literal was not emerging, these knowledge can only rely on the transmission from master to disciple oral instruction, and literal had been arranged afterwards, just note gradually, medical book occurred.These books have played sums up forefathers' experience and is convenient to the effect of spreading and promoting.The history in existing thousands of years of traditional Chinese medicine is that China people sum up with the very rich experience that disease is struggled for a long time, for the prosperity of the Chinese nation huge contribution is arranged.Because medicine medium-height grass class is in the great majority, so the books of record medicine just are called " book on Chinese herbal medicine ".According to textual criticism, when the Qin Han, book on Chinese herbal medicine is popular more, but these books on Chinese herbal medicine all are lost unfortunately, can not investigate.The existing herbal the earliest works of knowing is called Shennong's Herbal, and the author is not quite clear, according to the place name of wherein putting down in writing, possibly be that the revision forefathers of doctor family of Eastern Han Dynasty works forms.In large-scale Chinese medicine manufacturing enterprise, be in great demand to Chinese medicine is raw-material in the production process, because the raw-material quality of Chinese medicine all is a solid; And shape is varied, can't pack, before production becomes medicine materical crude slice; All need pulverize mixing, the raw material after pulverizing can't directly be used for production process because its impurity that contains or its one-tenth partial volume are different; Conventional artificial screening mode efficient is low; And labour intensity is big, can't satisfy the modern production of enterprise, needs to adopt Special Equipment to screen.
The utility model content
The purpose of the utility model is to overcome the shortcoming and defect of above-mentioned prior art, and a kind of equipment with multilayer screening function is provided, and this device structure is simple; Low cost of manufacture utilizes the multilayer mesh screen to screen, the screening process vibration; Improved raw-material utilization rate; Satisfy the production of different types of reagent simultaneously, improved screening effeciency simultaneously, reduced labor intensity of operating personnel.
The purpose of the utility model realizes through following technical proposals: a kind of equipment with multilayer screening function; The installing rack that comprises inner hollow and both ends open; The openend of said installing rack is provided with baffle plate; Said installing rack set inside has the several layers mesh screen, and the outer wall of said mesh screen contacts with baffle plate with the inwall of installing rack respectively.
The inwall of said installing rack is provided with some mounting bars, and said mounting bar is symmetricly set on the inwall of installing rack, and mesh screen all is arranged on the corresponding mounting bar, and contacts with mounting bar.
The said mesh screen size in aperture from top to bottom reduces successively.Raw material after pulverizing enter into down one deck through the hole on the mesh screen, and the volume of raw material that finally obtains is minimum.
The size of said baffle plate and the openend of installing rack are measure-alike.
The outer wall of said installing rack is provided with vibrating device.Vibrating device is used for making mesh screen vibrate in screening, improves the efficient of screening, shortens screening time.
In sum, the beneficial effect of the utility model is: this device structure is simple, low cost of manufacture; Utilize the multilayer mesh screen to screen; The screening process vibration has improved raw-material utilization rate, satisfies the production of different types of reagent simultaneously; Improve screening effeciency simultaneously, reduced labor intensity of operating personnel.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of mesh screen.
Mark and corresponding parts title in the accompanying drawing: 1-baffle plate; 2-installing rack; 3-mounting bar; 4-mesh screen.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is done further to specify, but the embodiment of the utility model is not limited only to this.
Embodiment:
Like Fig. 1, shown in Figure 2; A kind of equipment with multilayer screening function; The installing rack 2 that comprises inner hollow and both ends open; The openend of said installing rack 2 is provided with baffle plate 1, and said installing rack 2 set inside have several layers mesh screen 4, and the outer wall of said mesh screen 4 contacts with baffle plate 1 with the inwall of installing rack 2 respectively.Raw material are placed on the mesh screen 4 of the superiors, through vibrating device vibration, successively screening material.
The inwall of said installing rack 2 is provided with some mounting bars 3, and said mounting bar 3 is symmetricly set on the inwall of installing rack 2, and mesh screen 4 all is arranged on the corresponding mounting bar 3, and contacts with mounting bar 3.The mounting bar 3 of installing rack 2 both sides is six respectively, is convenient to the choices of raw materials to different size.
Said mesh screen 4 size in aperture from top to bottom reduces successively.The aperture of mesh screen 4 is used for raw-material passing through, and the Chinese medicine raw material after pulverizing are in the vibrations process of vibrating device, and the raw material that size is little successively pass through mesh screen 4, finally arrive bottom, the raw material of the size that obtains wanting.
The openend of the size of said baffle plate 1 and installing rack 2 is measure-alike.Baffle plate 1 is used to stop mesh screen 4, avoids in vibration processes, and mesh screen 4 breaks away from installing rack 2, causes security incident, and influence is produced.
The outer wall of said installing rack 2 is provided with vibrating device.Utilize vibrating device to vibrate, improve screening process, shortened the production cycle, reduced production cost.
Take aforesaid way, just can realize the utility model preferably.
