Abstract
The invention discloses a method for reducing dust of feeding tube and relative device. It arranges damp baffle plate inside the feeding tube, to generate resistance to reduce the material falling speed inside the feeding tube and the discharging speed when through the outlet of feeding tube, to reduce the impact force to reduce the dust. The invention can reduce fly dust, with simple structure, easy operation and better anti-dust effect.
Description
Technical field:
The present invention relates to a kind of device that is used for the minimizing dust emission from lay-off elephant trunk of convey materials, particularly a kind of lump material that is transferred that can prevent produces the device of the minimizing dust emission from lay-off elephant trunk of a large amount of airborne dusts greatly because of impulsive force when the discharging opening by emission of baiting chute falls to discharging point, belong to the emission of baiting chute technical field of convey materials.
Background technology:
At present, the emission of baiting chute that is used for convey materials, one all is smooth formula inwall for its inwall, the emission of baiting chute that adopts this smooth formula inwall is when convey materials, particularly in the process of the emission of baiting chute convey materials of high spud angle, when the material that is transferred (particularly lump material) by the bevelled emission of baiting chute on below rubber conveyor or other discharging point the time, because the emission of baiting chute inclination angle is big, its material descending speed is very fast, bigger to impulsive force that discharging point produced, can produce more airborne dust like this, thereby environment is polluted, and harm laborer's is healthy.
Summary of the invention:
The objective of the invention is to: provide a kind of simple in structure, easy to use, and can reduce the device of dust emission from lay-off elephant trunk, to overcome the deficiencies in the prior art.
The present invention is achieved in that the method for minimizing dust emission from lay-off elephant trunk of the present invention is: it adopts the mode that the damping slow punching is set in emission of baiting chute, with this damping slow punching the resistance that material produced that moves in the emission of baiting chute is reduced descending speed and material the discharge velocity when emission of baiting chute discharging opening of material in emission of baiting chute, can reduce the impulsive force that material produces the blanking point place like this, thereby reduce airborne dust.
The device that is used for the minimizing dust emission from lay-off elephant trunk of the inventive method is: it comprises the body of the emission of baiting chute that is provided with inlet point and discharging opening, is provided with at least 1 layer of damping slow punching that is provided with by U font opening on the lower wall panels in body and the sidewall paneling on both sides.
Under normal conditions, the sidewall paneling that is preferably in interior lower wall panels of body and both sides is provided with 5 layers of damping slow punching that is provided with by U font opening, and the U font openings of sizes of pressing the damping slow punching that U font opening is provided with is by descending arrangement, and promptly the U font opening the closer to the damping slow punching at discharging opening place is just more little.
Its lower wall panels and damping slow punching by the setting of U font opening on the sidewall paneling of both sides that is arranged in the body preferably adopts angle steel to make.
Owing to adopted technique scheme, when passing through this emission of baiting chute to rubber conveyor or other blanking point convey materials or lump material, its material enters in the body by inlet point, repeatedly collision can take place with dash plate in material in the process that descends, so just reduced the descending speed of material effectively, when material is from the body drop of discharge gate exhaust tube to rubber conveyor or on other blanking point, because speed is low, the impulsive force that is produced is just little, therefore the airborne dust that is produced just significantly reduces, thereby has reached antisoiling purpose.So the present invention compared with prior art, and the present invention not only has the advantage that can reduce the tremie pipe airborne dust, but also have simple in structure, easy to use, anti-dust effect.Adopt the present invention can cushion effectively material impulsive force, reduce airborne dust, improve working environment, laborer's is healthy thereby protected.
Description of drawings:
Accompanying drawing 1 is the structural representation of apparatus of the present invention;
Accompanying drawing 2 is that the K of accompanying drawing 1 is to view.
The specific embodiment:
Embodiments of the invention: adopt the mode that the damping slow punching is set in emission of baiting chute, with this damping slow punching the resistance that material produced that moves in the emission of baiting chute is reduced descending speed and material the discharge velocity when emission of baiting chute discharging opening of material in emission of baiting chute, can reduce the impulsive force that material produces the blanking point place like this, thereby reach the purpose that reduces airborne dust.
During enforcement, be preferably on the sidewall paneling on lower wall panels in the body 1 of the existing emission of baiting chute that is provided with inlet point 2 and discharging opening 3 and both sides and install at least 1 layer of damping slow punching 4 that is provided with by U font opening; But under normal conditions, be preferably on the sidewall paneling on lower wall panels in the body 1 and both sides 5 layers of damping slow punching 4 that is provided with by U font opening are installed, and will arrange by descending by the U font openings of sizes of the damping slow punching 4 of U font opening setting, be about to be provided with more for a short time, and make the minimum open dimension of the U font opening of damping slow punching 4 must be greater than the upperlimit of the lump material that is transferred the closer to the U font opening of the damping slow punching 4 at discharging opening 3 places.
Damping slow punching 4 by the setting of U font opening can adopt tubing or sheet material to make, but for the ease of installing, and preferably adopts the angle steel of different size to make and gets final product.
