Abstract

The utility model is a horizontal induced draft bed, which is a light impurity removing device in grain processing. The bed is a horizontal rectangular parallelepiped, two laterals of which are respectively provided with a vibrating motor; upper and lower parts of one end of which are respectively a material feeding throat and an air inlet; upper and lower parts of the other end of which are respectively an air inducer and a material outlet; and within which is positioned a slightly inclined rectangular punched bed board, over the bed board being an impurity removing space and under the bed board being a cold wind distributing groove. During the process that the punched bed board moves towards the material outlet, wind enters into the cold wind distributing groove by the air inlet and passes through the bed board and grains thereon, which were given from the material feeding throat, so that the light impurities are taken away, thereby solving the problem that light impurities cannot be removed clearly in the grain processing and cleaning technology.

Description

Horizontal air draught bed

Technical field

The utility model relates to a kind of light miscellaneous equipment that removes of grain processing, especially can be with the light assorted removing to greatest extent in the raw grain.

Background technology

At present, it mainly is vertical air draught road that grain processing removes light miscellaneous equipment, and it and vibratory cleaning screen banks are integral.Raw grain relies on certainly and reenters vertical air draught road after screening out assorted greatly and little mixing by vibratory cleaning, and in the process of this gravity flow, wind passes material flow, siphons away light mixing wherein.Because raw grain is very short to the distance between the vertical air draught road import from the vibratory cleaning sieve outlet, the vertical dirty speed of raw grain is also very fast, so the time of contact of wind and certain a part of raw grain is also very short, is to wear and mistake basically.In the contact of this short time, it is impossible wanting light assorted all exhaustion the in this part raw grain.Therefore on last one equipment of grain processing cleaning technology, still have dust to raise outward, cause environmental pollution, what is more important exerts an influence to product quality.

Summary of the invention

The purpose of this utility model provides a kind of horizontal light miscellaneous equipment that removes, and it can be with the light assorted removing to greatest extent in the grain.

The purpose of this utility model is achieved in that horizontal air draught bed is a horizontal cuboid, a vibrating motor is respectively adorned in the cuboid both sides, the upper and lower of cuboid one end respectively device charging aperture and air inlet are arranged, the upper and lower of the other end of cuboid device respectively has inlet scoop and feed opening, device has a rectangle punching bed board that slightly is inclination in cuboid, constitutes a bed body.Be covered with circular hole on the bed board, so that wind passes.For removing light assorted space, the bed board below is the cold wind distributing trough above the bed board.During work, grain enters from charging aperture, falls on the bed board, by the vibration of bed body grain is moved to the exit along whole bed board beat type on its length direction.In this process, the fan with low voltage air draught is inserted in the inlet scoop of horizontal air draught bed, wind enters in the cold wind distributing trough from the air inlet of horizontal air draught bed, and uniform distribution under whole bed board, make wind energy under bed board, evenly pass whole bed board and above grain to the inlet scoop, to take away light assorted in the grain.Because grain is in the state of beating on bed board always, the light assorted particularly dust that therefore can will stick on the grain is shaken off out as much as possible, so that wind siphons away; On the other hand, in the whole motion process of grain on bed board, there is wind ceaselessly to pass all the time, increased the time of contact between wind and the grain,

Therefore can remove gently mixing to greatest extent, reach and improve the purpose of removing light assorted effect.

Owing to adopt such scheme, utilize horizontal air draught bed light the mixing in the grain can be removed to greatest extent.

Among the figure, 1, folder aerofoil 2, air draught 3, frame 4, observe door 5, vibrating motor 6, bed board 7, drop down plate 8, deep bead 9, charging aperture 10, air inlet 11, cold wind distributing trough 12, discharging opening 13, rubber slab 14, hollow rubber spring 15, air register 16, angle steel 17, aspiration channel are flexible coupling 18, charging aperture is flexible coupling 19, the air draught road

The specific embodiment

Among Fig. 1, in the cuboid cylindrical shell that is welded by steel plate, be the bed board (6) of 5 ° of inclinations to discharging opening (12) direction, constitute a bed body with bolting one.The bed body is bearing in by hollow rubber spring (14) on the steel construction frame (3) that has crossbeam, drives the vibration of bed body by vibrating motor (5).The bed board upper part constitutes material and removes light assorted zone, and lower part constitutes the cold wind range of distribution.During work, material sifts out back being dropped on by charging aperture (9) from vibratory cleaning and drops down on the plate (7), drops down plate and is fixed by bolts between charging aperture and the bed board, plays cushioning effect.Material flow on the bed board certainly dropping down on the plate after buffering, under the acting in conjunction of the vibration of vibrating motor (5) and air draught, derives from discharging opening (12).Wind is entered in the cold wind distributing trough (11) by air inlet (10), and in the cold wind distributing trough, wind passes eyelet and material on the bed board then along whole bed board uniform distribution, and go out (2) from the inlet scoop.The inlet scoop links to each other with air draught road (19) by being flexible coupling, and inserts fan with low voltage.Folder aerofoil (1) is 60 ° and is welded on the place, inlet scoop, blows to the guiding effect, makes material be easy to flow to the exit from import department.Charging aperture vertical welding one deep bead (8) is to enter from charging aperture in order to reduce wind, allows wind enter from air inlet as far as possible.The rubber slab (13) that discharging opening (12) is located has been to close the wind effect, is utilize rubber slab soft, allows material can push rubber slab open and flows out, and does not allow wind enter from discharging opening again.Bed body both sides are respectively installed two and are observed door (4), so that observe the working condition in the bed body, can make access door again.

Among Fig. 3, arrow is represented flow direction of material.

Among Fig. 4, horizontal air draught bed and vibratory cleaning screen banks are integrated, and both shared frames are installed horizontal air draught bed below, and the vibratory cleaning sieve is installed above.Vibratory cleaning sieve is removed big assorted and little material after assorted and is directly entered horizontal air draught bed, can guarantee that material broad ways on bed board evenly distributes.Charging aperture be flexible coupling (18) be that the vibration of horizontal air draught bed and vibratory cleaning sieve is not disturbed mutually; The inlet scoop is flexible coupling (7) because the air draught road is to fix, and horizontal air draught bed then vibrates.The air draught road is fixed on the frame with angle steel (16).Air register (15) is used for regulating air quantity, makes material be beat type on bed board and moves ahead and don't be sucked away.

Claims
