Abstract
The invention discloses an ultra-fine powder classifying device. The ultra-fine powder classifying device is formed by connecting two or more scattering chambers in series through pipelines. Discharge valves are arranged at the bottoms of the scattering chambers. An outlet of the scattering chamber in the former stage is connected with an inlet of the scattering chamber in the later stage. A material/gas feeding port of the first scattering chamber is externally connected with a material/gas feeding pipe. The last scattering chamber is connected with a dust collector through a pipeline. A feeding hopper is arranged on the material/gas feeding pipe. An air inlet of the material/gas feeding pipe is connected with an air compressor. The ultra-fine powder classifying device is simple in structure, convenient to overhaul and maintain and high in classification accuracy and efficiency, and powder is fully scattered in the scattering chambers under the effect of compressed air; the device forms a closed space, the risks to human health are small, and the environmental pollution is low; collecting openings are formed in the lower ends of the scattering chambers, and the powder is conveniently collected and recycled; the scattering chambers and the pipelines are plastic parts, and no pollution is generated to the powder; and the collected powder can be directly used without being treated, and the production efficiency is effectively improved.
Description
Technical field
The present invention relates to a kind of grading plant of superfine powder, particularly a kind of airflow classification device.
Background technology
Superfine powder is almost applied to all industries of national economy, and it is transformation and the basis promoting the new industry development such as paint, information recording carrier, fine ceramics, electronic technology, new material and biotechnology, is the starting point of modern high technology.
But superfine powder because of specific area and surface energy comparatively large, very easily reunite, traditional air current classifying and sieve classification are difficult to the object reaching classification, and classification efficiency is low, and effectiveness of classification is poor, very easily contaminated etc.Current classification can reach the object of superfine powder classification to a certain extent, but there is many uses restriction, and the powder after classification carries out drying easily produces the phenomenon that hardens, and is unfavorable for the processing use in later stage.
Summary of the invention
The object of the present invention is to provide a kind of structure simple, be convenient to check dimension, effectiveness of classification and the high superfine powder grading plant of efficiency.
The object of the invention is to be achieved by the following technical programs, a kind of superfine powder grading plant, include dispersing chamber, the bottom of dispersing chamber is provided with discharge valve, it is characterized in that, described device is in series by pipeline by two or more dispersing chamber, and the outlet of previous stage dispersing chamber is connected with the entrance of rear stage dispersing chamber, external charging/the tracheae of charging aperture of first dispersing chamber, last dispersing chamber connects a dust-precipitator by pipeline.
Further technical scheme of the present invention also has following characteristics:
Described charging/tracheae is equipped with loading hopper, and the air inlet of charging/tracheae connects air compressor.
Described dispersing chamber is plastic bottle, and described pipeline is plastic conduit.
The present invention is by multiple dispersing chamber units in series, adopt compressed air delivery superfine powder, under airflow function, make the powder entered in each dispersing chamber fully can be dispersed into individual particle, then natural subsidence collecting under gravity, fail the powder of sedimentation enters next dispersal unit under airflow function, so repeatedly, after filtering finally by cloth bag collector, gas is discharged, in collector at different levels, just can obtain the different powder of particle diameter.
Beneficial effect:
Structure of the present invention is simple, and be convenient to inspection dimension, powder fully disperses under compressed air effect in dispersing chamber, effectiveness of classification and efficiency high; Device is confined space, and little to human health damage, environmental pollution is little; Dispersing chamber lower end is provided with collection mouth, and powder is collected and reclaimed conveniently; Dispersing chamber and pipeline adopt working of plastics, pollution-free to powder, collect powder and can directly use without the need to process, effectively enhance productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, the invention provides a kind of superfine powder grading plant, be in series by pipeline 5 by three dispersing chambers 1, the outlet of previous stage dispersing chamber is connected with the entrance of rear stage dispersing chamber, each dispersing chamber is provided with Pressure gauge 10, external charging/the tracheae 2 of charging aperture of first dispersing chamber, feed hopper 8 charging/tracheae 2 is equipped with, the air inlet of charging/tracheae connects air compressor 6, dispersing chamber 1 adopts diameter phi=150cm plastic bottle, bottle bottom is funnel shaped feeder 4, the bottom of feeder 4 is provided with discharge valve 3, described pipeline adopts the plastic conduit of diameter phi=5cm, last dispersing chamber connects by pipeline the dust-precipitator 7 that is equipped with the cloth bag that gathers dust.Ensure the collection of non-sedimentation powder, ensure the rate of recovery of powder and reduce the pollution of environment.
Direct employing plastic chamber is as powder dispersing chamber unit, use plastic tube to be connected by each dispersing chamber, the bottom of each dispersing chamber is provided with collection mouth, and the charging aperture of dispersing chamber is higher than collection mouth, ensure enough spaces and collect sedimentation powder, device afterbody adopts dust-precipitator 5.
Powder is added by feed hopper 8, enters dispersing chamber 1 after compressed air ejection, and natural subsidence is in feeder 4 under gravity, and can discharge collection by discharge valve 3.Non-sedimentation powder enters next dispersing chamber under airflow function, and after last powder and the dust-precipitator 7 of admixture of gas through being equipped with the cloth bag that gathers dust filter, clean gas is discharged by air-introduced machine 9.
Above-described embodiment is as better embodiment of the present invention; describe technical conceive of the present invention and essential implementation in detail; not that protection scope of the present invention is limited; all any simple modification of doing according to Spirit Essence of the present invention and equivalent structure transformation or modification, all should be encompassed within protection scope of the present invention.
