Abstract

The utility model discloses a wind selecting bran remover which is composed of a shell, rotors, and a blower, and the shell, the rotor, and the blower share the same main shaft; the utility model is characterized in that the rotor is composed of a main shaft, a round plate fixed on the main shaft, and a puncturing rod; a size body is provided with a radial material feeding mouth; the lower part of the size body is provided with a bran expelling air return mouth which is connected with a blower outlet by a material unloading apparatus. With the action of centrifugal force, fine particles are concentrated the shaft periphery and are absorbed in by the shaft end blower, and large bran particles are squeezed on the air return mouth and a uniform bran net; The upward flow makes the bran and the air fully mix, and the bran is cleaned again. The utility model has the advantages of strong hitting and high bran powder separating efficiency.

Description

Wind selecting bran remover

Selection by winnowing bran finisher of the present utility model belongs to wheat flour milling machinery.

At present, the bran finisher of flour processing industry use both at home and abroad all by the design of screening principle, has vertical and horizontal two kinds.Design feature is made up of re-pack rotor and screen drum.Screen drum is to go out ∮ 1, circular hole below the θ mm with steel plate, makes lonely shape and polygon cylindrical shell.Shortcoming is that sieve plate manufacturing process difficulty is big, the cost height, and percent opening is low, and the percent opening of external like product is 22%, and domestic percent opening is at 10-15%.On the other hand, percent opening is low must make bran powder separation rate low.From design principle, since the rotation of the high speed of the rotor that re-packs, linear velocity 20-26 meter per second, produce centrifugal action, make the bigger wheat bran of particle arrive first skin and contact with compass screen surface, and the less pruinescence of granularity is difficult to be sifted out in the middle of being rolled in, vertical this defective is more outstanding.

The purpose of this utility model provides a kind of high sorting index bran finisher that utilizes mechanical force and selection by winnowing principle to be designed to.

This selection by winnowing bran finisher comprises rotor, housing and forms at the blower fan of housing one end shared same main shaft with it; It is characterized in that rotor by main shaft 2 different with thereon fixing disk 16, bar 17, size re-pack and sampler 8 is formed; Main shaft 2 axially is installed in the housing 5.Housing 5 is tubulars, splits at horizontal plane, and its quarter turn is two planes at right angle each other, studs with the protection liner plate in the housing; Be provided with radially charging aperture 3 on the plane of a relative end with blower fan on the housing 5, row's bran return air inlet 7 is arranged below housing 5 middle parts, the same end of housing charging aperture 3 is also established wind axial air regulating port 1; Return air inlet 7 on the housing 5 links to each other with the centrifugal discharge device by pipeline 9 with air regulating port 1.Sampler 8 is with blade and hub axis is angled is welded into one, and blade outer rim and axis are a cone angle.

Selection by winnowing bran finisher of the present utility model combines Mechanics of Machinery and moving learning of air, beats bran and selects powder to carry out simultaneously, and the material that particle is little concentrates on around the axis, is arranged on the blower fan inspiration of axle head, finishes selection by winnowing one time.The big wheat bran of particle is at skin, therefore be provided with row's bran return air inlet 7 and even bran net 6 in the casing bottom, utilize updraft that wheat bran, air-flow are fully mixed, being contained in fine powder in the wheat bran like this will sail against the current and enter blower fan, and wheat bran can not pass through owing to the high speed rotation of sampler 8, outside must the even bran net discharge machine on return air inlet, realize recleaning to wheat bran.Also be provided with the pipeline 9 that communicates with discharger in addition and constitute the blower fan loops at housing return air inlet 7 and air regulating port 1, write off dust laden air double purification device, form self-loopa.

This design and structure make this machine strong to the wheat bran hitting power, bran powder separation rate height, and the flour extraction height, machine volume is little, and manufacturing process is simple, and cost is low, and spare part is changed easily, and self-circulation system has reduced process procedure, promptly purifies air and saves the energy.

Accompanying drawings embodiment:

Accompanying drawing 1 is the schematic diagram of selection by winnowing bran finisher

Accompanying drawing 2 is sampler front views in the selection by winnowing bran finisher

Accompanying drawing 3 is sampler A-A views in the selection by winnowing bran finisher

During assemble rotor, the disk 16 with two pairs of symmetrical holes is enclosed within on the main shaft 2, plugs bar 17, re-pack and the spacer handover be through on the bar 17, then bar 17 two ends are positioned on the disk with pin.Interlaced the opening that re-pack, size is big re-packs and 4 is installed in feed end, re-packs for a short time 15 to be contained in the middle part, then sampler 8, draught fan impeller 14 is installed successively from axle 2 other ends, in the housing 5 that the rotor load level that assembles is split.Motor 13 drives belt pulley 11 by V-belt 12, makes main shaft 2 rotation at a high speed.Material tangentially enters impingement region by charging aperture 3, under the bump of 4 strike and housing right-angle plane that re-packs, endosperm of adhering on the wheat bran and wheat bran break away from, under action of centrifugal force, be broken into powder, under inlet feed was constantly squeezed wind-force effect with axial air regulating port, material was pushed to selected district gradually again.Selected district by housing 5, re-pack 14 for a short time, sampler 8 and even bran net 6 form.Even bran net 6 is to weave into the 10-15mm square hole with steel wire, covers on the exhaust outlet 7, and fine particle enters blower fan by sampler 8 in the material, and thicker wheat bran is then by outside row's bran return air inlet 7 discharge machines.Return air inlet is of a size of 300 * 180mm.Primary mixture is told powder by centrifugal discharge device 10 through blower fan.The air that centrifugal discharge device 10 is discharged is then returned in the machine by pipeline 9, thereby has formed an airflow circulating system, has finished the bran powder and has separated.
