The specific embodiment

The utility model is on the principle of work basis of unpowered dust exhaustor; Change the material part into enclosed construction; Deflector chute 6 former oblique idlers are replaced by the supporting plate 7 that high abrasion resisting material is processed; Transmission is more steady, and interior in addition outer closure can't leak outside material, thereby has solved the difficult problem that transfer transmission is leaked material.

Below in conjunction with accompanying drawing the utility model is elaborated.

Shown in Figure 1 is the structural representation of the utility model.

But the utility model comprises the soft curtain of material blanking tube 1, counter flow pipe 2, dirt air separation 3, air connectivity hole 4 resistance trimming dirt 5, deflector chute 6, go up belt 9 and following belt 8, closed box 10.

Said material blanking tube 1 is between last belt 9 and following belt 8, and the material on the last belt 9 is transported to down on the belt 8 through this material blanking tube 1, thereby realizes once transhipment.

The both sides of said dirt air separation 3 are provided with air connectivity hole 4, and front end is provided with baffle plate, are used to stop dust to pass through, and this dirt air separation 3 is arranged on material blanking tube 1 the place ahead.

Said counter flow pipe 2 is arranged between the top and material blanking tube 1 of dirt air separation 3.

But the soft curtain 5 of said resistance trimming dirt can be provided with many places according to the length of closed box 10.

Specify the working process of the utility model below in conjunction with accompanying drawing.

The working process of the utility model is following: material is all fallen on the following belt 8 through material blanking tube when last belt 9 is sent to the terminal, begins to occur dust simultaneously.

The part dust that is positioned at rear side is because the compelled priority that stops of whereabouts material is moved, and through being positioned at the filtering net of rear side, fresh air flows out through the deflation hole that is positioned at its top, and compelled the turning back of the dust that is obstructed moves ahead with material.

Most of dust is with the direction operation that moves ahead of material falling edge belt, because the energy depletion belt that falls back progressively behind the upper wall of a part of dust bump belt top closed box 10; All the other most of dust that move ahead along belts 8 down get into to dirt air separation 3; Fresh air is discharged through air connectivity hole 4, because dropping of logistics forms malleation in the dirt air separation, simultaneously because dropping of logistics produces negative pressure to counter flow pipe; Under so positive action of negative pressure; Dust in the dirt air separation 3 returns material blanking tube 1 along counter flow pipe 2, and dust reduces potential energy along kinetic energy in counter flow pipe 2 uphill process and increases, simultaneously some heat exhaustion portion of energy of inwall generation friction generates of dust and counter flow pipe 2; Collision also consumes part energy between the dust; When dust during to the top of counter flow pipe 2 kinetic energy reach the minimum potential energy maximum because the top of dust counter flow pipe 2 will be higher than the interface that communicates with material blanking tube 1, air-flow forward gets into material blanking tube 1 and accomplishes effectively and circulate like this; Through such circulation, belt 8 under the preliminary depletion of the energy of most of dust falls back.

But the dust that the part continuation moves ahead with material also can run into stopping of the soft curtain 5 of some resistance trimming dirt forwardly and return, and through several basic depleted of energy of turning back, when material moves to the dust exhaustor outlet, does not have dust basically.

Be the top design of closed box 10 that semicircle shape can make dust and collision rear, closed box 10 tops accelerate the speed of its energy decline to inconsistent to form new collision in addition, be unlikely to occur the dead angle simultaneously, more can form the effect of thorough dedusting.

This closed dedusting method is on the basis of aerodynamic principle, and the pressure that utilizes air when flowing, to be produced converts power to, dust laden air is got into carry out inertia, gravity settling, filtration etc. behind the dirt air separation 3 to separate dedusting automatically; Dust falls back to down on the belt 8 and is pulled away; Take off the dirt air and be discharged to space outerpace through air connectivity hole 4, effectively solve the air pressure problem in the enclosed environment, efficiency of dust collection can reach more than 99%; Enclosed construction has also solved the problem of blanking simultaneously; It has changed traditional single dust removal design theory, is the upgraded product of traditional dust exhaustor, is the brand-new design that leakproof combines with dedusting.
