The scavenging fan and the gas stream friction type material cleaning unit thereof have the advantages of simple structure, good use effect, good scavenging effect, etc. The materials cleaned by the utility model can realize the requirement of high cleanliness. The utility model is the optimal device at present.
Description
The utility model relates to device to grain or processing of granular solids material surface cleanness and impurity separation.
Known material wind selection machine has hand or two kinds of motor-driven wind wheels, grain or the blowing of granular solids material that certain wind-force that its principle system utilizes wind wheel to produce falls naturally to utilizing gravity, it is descended slowly and lightly at certain space, allow blow off zone within certain level of the solid material particle that to choose, and allow the impurity material dust particle of light specific gravity blow off to certain level distance zones of different in addition, thereby reach the purpose of cleaning, the greatest problem that this class winnowing machine exists is that the granule materials chance that is subjected to blowing clearly is less.In order to address this problem, the someone has designed a kind of winnowing machine, is the normal temperature wind of the certain wind-force of tool is blown upward from the vibrating screen mesh below, makes material particles be subjected to blowing clearly of wind-force several times from compass screen surface one end motion to the process of the other end.Make cleaner that the material surface blows clearly.But because material is subjected to the chance and the wind-force that blow clearly limited, so the granule materials surface still speckles with many particle dusts, and cleaning of solid materials such as granular material of having relatively high expectations for cleannes such as high quality white rice still do not reach the requirement of high cleanliness.
The purpose of this utility model is exactly the deficiency that exists at prior art, provides a kind of simple in structure, the gas current friction type sorting purpose device of Scavenging fan that is easy to make and composition thereof.
In order to achieve the above object, the utility model is realized in the following way.
Scavenging fan integral body is column, and the middle and lower part is equipped with screen 6, and screen 6 tops one side is provided with charging aperture 3, and opposite side is provided with discharging opening 7.
Scavenging fan top also can be provided with the container of diameter greater than the bottom.
For making the material charging even, 3 places also can be provided with screw feeder 2 at charging aperture, and in order to remove a small amount of material that leaks in screen below aperiodically, the bottom is provided with unconventional discharging opening 9, air inlet 1 is in screen bottom one side, and joins with the end wall of unconventional discharging opening 9.Be provided with air outlet 4 at container top.
Scavenging fan integral body can be a kind of in the shapes such as cylindric, oval column, rectangle column, polygon prism shape, and rectangle or oval column are best.
A kind of gas current friction type sorting purpose device that utilizes Scavenging fan of the present utility model to form, it is characterized in that: form by air blast 10, Scavenging fan 12, cyclone dust collectors 14, sack cleaner 16, air-introduced machine 18, air blast 10 links to each other with Scavenging fan 12 by airduct 11, Scavenging fan 12, cyclone dust collectors 14, sack cleaner 16, air-introduced machine 18, is connected to a complete device by airduct 13,15,17.
Sorting purpose device of the present utility model is to utilize the gas current friction principle to design, it mainly is the design concept of Scavenging fan, whole Scavenging fan is a column, also can be up big and down small, there is a multi hole grid middle and lower part, and screen is divided into upper and lower two spaces with Scavenging fan, and normal temperature wind, the wind that introduces from air blast through airduct in following space blow from bottom to top through the screen hole, last space is in Scavenging fan one sidewall near screen one charging aperture is set, and sets out the material mouth at another sidewall of Scavenging fan.The method of cleaning is: granular material such as rice by screw feeder after charging aperture is forced into Scavenging fan, above screen, blown afloat by high wind, arrive after the certain height because wind speed reduces by the gravity effect whereabouts naturally, drop near the screen place, blown afloat by high wind once more, fall once more, through blowing afloat the whereabouts many times, particle surface repeatedly is subjected to gas current friction, and that is cleaned is very clean, owing to the reason of continuous feed, the middle and lower part in space on the Scavenging fan, charging oral-lateral and discharging oral-lateral material produce concentration difference in spatial distribution, and material will be from charging aperture to the irregular movement of discharging opening direction generally, after discharging opening flow out naturally.Space certain altitude place on Scavenging fan, the cross section increases suddenly, and the top of blowing clearly is connected into a system with cyclone dust collectors, sack cleaner, blower fan successively through airduct.Because wind speed and sectional area are the negative relation, part than the material of granule by wind to cross section increase place of last space, wind speed will further reduce suddenly, gravitate, these small particles materials will fall, impurity material and dust particle that proportion is less will be brought into cyclone dust collectors with air-flow, and major part is collected by cyclone dust collectors.Thinner lighter particle dust continues to be brought into sack cleaner with air-flow and is collected, and the clean gas behind the cloth bag filtration enters atmosphere.
Fig. 1 is the utility model gas current friction type cleaning plant Scavenging fan schematic diagram;
Fig. 2 is the utility model gas current friction type cleaning plant structural representation;
Among the figure: space, 9 unconventional discharging openings, 10 air blasts, 11 airducts, 12 Scavenging fans, 13 airducts, 14 cyclone dust collectors, 15 airducts, 16 sack cleaners, 17 airducts, 18 air-introduced machines under space 6 screens, 7 discharging openings, 8 Scavenging fans on 1 airduct, 2 screw feeders, 3 charging apertures, 4 suction opeings, 5 Scavenging fans.
Compared with prior art the advantage that has of the utility model is:
1, Scavenging fan is simple in structure, and cost is low, is easy to make, and blows clearly effectively, and the solid material after this device blows clearly, grain can satisfy the high cleanliness requirement.
2, because this device is to adopt multistage dedusting, no environment and dust pollution.
