Abstract

The utility model relates to a dust removing device for transferring straps. As the current dust removing station for transferring straps which employs a rotary channel structure can achieve effective dust removing effects only by assisting with the facilities like spraying, the current removing station for transferring straps can not be applied into the technical fields which do not allow to be mixed with water; moreover, a series of technical problems like seasoning affection, complex structure and large maintaining amount are existed. Therefore, the utility model provides an non-power dust removing station; a rotary reduction chamber is arranged on a catching groove based on the structure of the original rotary channel; a seal soft curtain is arranged at the front end of the rotary reduction chamber and an air deflector is arranged inside the rotary reduction chamber, thus leading the dust removing station to form two air flow rotary dust removing processing spaces. Practice shows that the technical scheme does not need the power support of water and electricity, has excellent dust removing effect and small maintaining amount, and can be broadly applied to the transferring dust removing fields of materials like chemical products, cement, limes, and the like.

Description

Unpowered dust removing station

Technical field

The utility model relates to the dusting equipment of belt transhipment.

Background technology

The belt transporter mainly includes blanking barrel and following transmission belt catching groove, and blanking barrel vertically is provided with and communicates with catching groove, and both interior spaces have constituted dust processing space, can trickle device for reducing dust, electrostatic dust collector be set in this space or seal facility such as soft curtain.A kind of air-flow Clothoid type dedusting technology has appearred in the prior art, promptly be communicated to blanking barrel top the chicane that guiding dust impact air-flow is back to blanking barrel is set by catching groove, in its design concept, by airflow dust up in mainly through the conversion of kinetic energy and potential energy, make the dust airflow kinetic energy be able to effective attenuation, thereby impel dust settling, reach the dedusting purpose.But dust gas shock kinetic energy is huge, and the only single room structure of setting up can't reach national dedusting technology standard-required, thereby must be aided with the trickle dust removal installation.Yet many materials are not allow water mixing, do not allow water mixing as materials such as chemical products, cement, lime, even if the material of energy water mixing as coal in power plant, can advance blast furnace and use after also must drying, need huge energy support; Moreover transporter is open-air mostly to be used, and especially at northern area, water lines is frozen to block easily, bursting by freezing, so a lot of user is the various troubles of avoiding the operation in winter and safeguarding, the water source that usually breaks performs practically no function whole dust collector; Also have electrical equipment, water lines parts more, maintenance is bigger on the one hand, on the other hand in inflammable and explosive occasion, the application of electrical equipment must meet corresponding explosion-proof criteria requirement, sometimes or even restriction use.

Summary of the invention

Goal of the invention of the present utility model is to provide a kind of and need not electric power and electric equipment, need not water dedusting and pipeline setting thereof, realizes the unpowered dust removing station of unpowered dedusting operation.The unpowered dust removing station that technical solutions of the utility model represented, comprise that button covers in down the catching groove of transmission belt The initial segment, blanking barrel with lower end feeding catching groove, the place ahead of the catching groove port of blanking barrel, upwards be communicated to blanking barrel top by the catching groove top and be provided with chicane, chicane is communicated with the place with catching groove the place ahead catching groove is provided with the decompression chamber of circling round that the spatial altitude direction swells, decompression chamber front end and the catching groove communications ports of circling round is provided with the soft curtain of sealing, circle round and be positioned at catching groove main body air-flow top in the decompression chamber, and be the deflector shield that is not more than the right angle with the setting of main body air flow line, form the runner that circles round along the deflector shield periphery.

The unpowered dust removing station technical scheme that the utility model proposes, be to combine with existing chicane structure, constitute tow channel gas and flowed back to the structure setting of revolving, process that the dust impact air-flow circles round by first road and second road circles round, through the conversion between potential energy and the kinetic energy, dust granules and chicane, circle round decompression chamber wall surface and deflector shield etc. clash into, rub simultaneously, make the decay of particle kinetic energy actv. and are able to a large amount of sedimentations, thereby realize the technical purpose of dedusting.Practice is proof also, and the technical program is a kind of dust removal installation that need not to be provided with again liquid distribution and the support of other energy, can reach the dedusting technology standard-required.The technical program is owing to need not power supports such as water, electricity, and simple in structure, and maintenance is minimum, and its field of application is expanded simultaneously, can be applicable to the transhipment dedusting field as materials such as chemical products, cement, lime.

The specific embodiment

Unpowered dust removing station of the present utility model, embodiment structure comprise that button covers in down the catching groove 3 of transmission belt 4 The initial segment and the blanking barrel 1 that the lower end feeds catching groove 3 as shown in Figure 1.Catching groove upper wall by catching groove port the place ahead of blanking barrel 1 is drawn, and is communicated to blanking barrel 1 top chicane 2 is set, and this chicane 2 is curved channel or inverted V-shaped passage, and promptly chicane 2 has the channel direction of air-flow forward being incorporated into blanking barrel 1 air-flow.On the catching groove 3, air-flow the place ahead of being positioned at chicane 3 is provided with the decompression chamber 5 of circling round that the spatial altitude direction swells, the port position that decompression chamber 5 front ends that circle round feed catching groove 3 body plenum is provided with the soft curtain 50 of sealing, and the top that is positioned at catching groove main body air flow line in the decompression chamber 5 of circling round is provided with this air flow line and is the deflector shield 51 that is not more than the right angle.Catching groove main body air-flow continues to navigate within when circling round decompression chamber 5 scopes, be hampered in the soft curtain 50 of the sealing of front end, up and enter the decompression chamber of circling round by deflector shield 51 guiding, in order to strengthen the directional tagging of deflector shield, some deflector shields be arranged in parallel in the decompression chamber 5 of circling round, each deflector shield upper end is provided with deflection plate 52, by each deflector shield 51 ' as the place ahead deflection plate 52 ' air-flow forced guiding plate, part air-flow is shunted continuation and is flowed by the inertia that moves ahead, another shunting is by importing catching groove main body air-flow along rear deflector shield 51 ' descending guiding, promptly form a plurality of runners that circle round for a short time at each deflector shield and the up periphery of deflection plate thereof, at it in each process of circling round, air-flow carry that dust is changed through potential energy and kinetic energy again secretly and and locular wall, collisions such as deflector shield, its kinetic energy is further decayed and is deposited in down on the transmission belt, and the clean-up effect of airflow dust is particularly evident.
