Abstract

The invention relates to a dust eliminating device, in particular to a dust discharging device achieving dust eliminating through a telescopic pipe. The dust discharging device comprises a dust discharging control valve (1), a dust inlet (2) of the dust discharging control valve (1) is connected with a dust discharging port of a dust removal device, a dust outlet (3) of the dust discharging control valve (1) is connected with the telescopic pipe which is vertically arranged and composed of multiple segments of casing pipes (4), the lowermost-segment casing pipe (4) is fixedly connected with a sling (6), and the sling (6) is connected with a winch (7) which enables the sling (6) to upwards telescope; the exterior of the telescopic pipe is sleeved with a dustproof bag (8), the upper end of the dustproof bag (8) is fixed to the uppermost-segment casing pipe (4) or the outer wall of the dust discharging control valve (1), the lower end of the dustproof bag (8) is fixed to the lowermost-segment casing pipe (4), and telescoping of the telescopic pipe can be controlled through retracting and releasing of the sling (6). The dust discharging device has the advantages of being simple in structure, low in cost and good in dust raising prevention effect.

Description

Expansion pipe dust elimination ash-discharging device

Technical field

The present invention relates to dust elimination device, it is specifically related to a kind of ash-discharging device adopting expansion pipe dust elimination.

Background technology

Power plant and some chemical plant, when producing, can produce a large amount of dusts, filtered by cleaning apparatus and can regularly clear after collecting. These dust are usually relatively thin, and slightly putting wind will fly upward over the sky, is polluted by the environment of periphery, and endangers the healthy of operation personnel. Overhead all there is certain altitude in the cinder-discharging port of usual cleaning apparatus, when unloading ash, dust punching will cause very big airborne dust to ground or railway carriage. Up to the present this problem is not still resolved.

Summary of the invention

Technical problem to be solved by this invention is: provide a kind of expansion pipe dust elimination ash-discharging device for the problems referred to above, to solve airborne dust problem when cinder-discharging port unloads ash.

The technical solution of the present invention is: expansion pipe dust elimination ash-discharging device, comprise and unload ash control valve, the cinder-discharging port of the described ash inlet and cleaning apparatus that unload ash control valve is connected, the ash output hole unloading ash control valve is connected with the expansion pipe being made up of some joint sleeve pipes of vertically setting, casing starter is fixedly connected with hoist cable, hoist cable is connected with windlass, so that it upwards shrinks, the outer cover of expansion pipe has Dust-proof bag, the upper end of Dust-proof bag is fixed on goes up on joint sleeve pipe most or unloads ash control valve outer wall, lower end is fixed on and descends on joint sleeve pipe most, the flexible of expansion pipe can be controlled by the folding and unfolding of hoist cable.

The technique effect of the present invention is: it has the advantage that structure is simple, cost is low and prevents airborne dust effective, it is arranged on cinder-discharging port place, expansion pipe is raised gradually with the continuous accumulation of dust, the impact point of dust is limited in expansion pipe, airborne dust outside pipe is served good restriction, and maximum degree reduces the pollution to environment and personnel.

Accompanying drawing explanation

Fig. 1 is the structural representation of the present invention.

Embodiment

As shown in Figure 1, expansion pipe dust elimination ash-discharging device, comprise and unload ash control valve 1, the described ash inlet 2 unloading ash control valve 1 is connected with the cinder-discharging port of cleaning apparatus, the ash output hole 3 unloading ash control valve 1 is connected with the expansion pipe being made up of some joint sleeve pipes 4 of vertically setting, casing starter 4 is fixedly connected with hoist cable 6, hoist cable 6 is connected with windlass 7, so that it upwards shrinks, the outer cover of expansion pipe has Dust-proof bag 8, the upper end of Dust-proof bag 8 is fixed on goes up on joint sleeve pipe 4 most or unloads ash control valve 1 outer wall, lower end is fixed on and descends on joint sleeve pipe 4 most, the flexible of expansion pipe can be controlled by the folding and unfolding of hoist cable 6. hoist cable 6 adopts two, and symmetry is located at expansion pipe both sides. go up most joint casing pipe sleeve outside the ash output hole 3 unloading ash control valve 1, or go up joint sleeve pipe most and be fixed on ash output hole 3 peristoma.

The described ash control valve 1 that unloads, for butterfly valve, has the simple feature of structure.

The described ash control valve 1 that unloads is for spiral propeller, it is possible to accurately controlling ash quantity, the dust outside sleeve pipe 4 is blown afloat by the air-flow preventing out the excessive formation of ash quantity stronger.

Described joint sleeve pipe 4 is descended to be provided with balance weight body 9 most.

The sleeve pipe 4 of described expansion pipe except next joint is provided with ring set 5, and hoist cable 6 is connected through ring set 5 with windlass 7.

When unloading ash, first expansion pipe is launched, make to descend joint sleeve pipe to be against on transport vehicle box most, then open valve and unload ash downwards, in the process unloading ash, upwards shrink expansion pipe gradually so that it is being enclosed within ash point all the time peripheral, completing until unloading ash.
