Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of removal of impurities pneumatic separation device of the invention, including aspiration channel 4, the miscellaneous tank of the collection being connect with aspiration channel 4
5, discharge pipe 14, the slag notch 10 being connect with the miscellaneous tank 5 of collection；Installation is provided with the blower 9 of selection by winnowing pressure on discharge pipe 14；Collect miscellaneous
Air regulating port 6 and regulating valve 7 are provided on tank 5, the regulating valve 7 is located at the air regulating port 6.
The cereal for needing primary election to clean, such as paddy, corn, wheat, drop into material plate through the feed inlet on feed bin 11
On 13, cereal and impurity are scattered and the impurity of lighter in weight are sucked aspiration channel convenient for aspiration channel 4.Such as selection by winnowing pressure in aspiration channel 4
It is smaller, effectively impurity etc. cannot be sucked, if selection by winnowing pressure is larger, then the particle of lighter in weight and not full cereal also with
Can suck in aspiration channel 4.By adjusting regulating valve 7, the opening-closing size of air regulating port 6 is controlled, can be realized to the miscellaneous tank of collection 5 and go out
The selection by winnowing flow velocity of air hose 14 and the control of pressure.The opening of air regulating port 6 is bigger, and the air for entering the miscellaneous tank 5 of collection from air regulating port 6 is got over
More, the negative pressure collected in miscellaneous tank 5 is just smaller, realizes that relatively heavy particle and not full cereal drop into collection in the miscellaneous tank 5 of collection
In the collecting bin 15 of miscellaneous 5 lower part of tank, and lighter layering, husk of relative weight etc. by collect enter after miscellaneous tank 5 discharge pipe 14 by
Slag notch 10 is discharged.
The particle and not full cereal for being convenient to clean and collecting and collect and fall into miscellaneous tank 5 are provided in the lower part of collecting bin 15
Discharge nozzle 16.It is provided on the discharge nozzle 16 and adjusts wind branch pipe 17, the air regulating port 6 is arranged on the tune wind branch pipe 17.
In this way, air regulating port 16 can reach the work of adjusting since the position of air regulating port 16 is not or not the dynamic pressure direction of 4 outlet air of aspiration channel
With, but be unlikely to in discharge pipe 14 selection by winnowing pressure and flow velocity generate excessive influence, and the precision adjusted is easy to control.And
It drops into the particle in discharge nozzle 16 and not full cereal to take out from the second discharge port 8 on discharge nozzle 16, the second discharge port 8
It is controlled by switch 12 to open and be closed.
Dust hood 3 is installed in air inlet one end of the aspiration channel 4, the dust hood 3 passes through aspiration channel 4 and the collection
Miscellaneous tank 5 is connected.Dust hood 3 increases the active area of 9 suction of blower, improves the working efficiency of blower 9 to greatest extent,
In order to facilitate the cereal collected Jing Guo dedusting, it is preferred that be provided with feed bin below the air inlet of the aspiration channel 4
11, the bottom of the feed bin 11 is provided with the first discharge port 2.Cereal enters in feed bin 11, and under the action of blower, impurity is obtained
To removing, the cereal by dedusting is discharged by the first discharge port 2.
In order to ensure the impurity in cereal can be all sucked out under the suction of blower 9 to the maximum extent, it is preferred that the material
It is fixedly installed the oriented inclined material plate 13 in first discharge port, 2 direction at the feed inlet 1 in storehouse 11, the material plate 13 is to institute
It states and is formed with material channel between the inclined one end in 2 direction of the first discharge port and 11 inner wall of the feed bin.Cereal from feed inlet 1 into
Enter feed bin 11 and be scattered on material plate 13, and then is moved on material plate 13 to 2 direction of the first discharge port, it is then logical from material
Road continues to fall to the bottom of feed bin 11, finally discharges from the first discharge port 2.Material plate 13 extends cereal in feed bin 11
Run duration, while cereal being scattered, tiles and comes, improve purification capacity.
Regulating valve 7 can be realized the adjusting to 6 opening-closing size of air regulating port, in order to realize above-mentioned technical effect, the adjusting
Valve 7 is barrier switch or gate valve.Barrier switch and gate valve can realize the opening and closing of air regulating port 6, and then control at air regulating port 6
Intake.
The above are specific embodiment of the present utility model, from implementation process as can be seen that the utility model provides one kind
It is adjustable the removal of impurities pneumatic separation device of removal of impurities intensity, by adjusting the regulating valve at wind-supplying mouth, change increases the negative pressure in cavity, into
And realize and be adjustable selection by winnowing pressure, convenient for cereal in recycling impurity etc..
