Description

Crashproof negative pressure secondary dust settler

Technical field

The utility model relates to dust settler, relates in particular to the unit deduster used of mining on colliery, is specially crashproof negative pressure secondary dust settler.

Background technology

Along with improving constantly of modern mine coal-cutting mechanization, coal production growing, dust concentration is also in continuous increase, therefore take the measure of various reduction dust concentration, downhole powder dust concentration is reduced to below the concentration of defined in < < safety regulations in coal mine > >, become the most important thing in mine dust-proof working, also become an important ring of mine safety production.The harm of dust is very large, is engaged in for a long time the worker of digging and dust work environment, if measurements for reduction is incapable, very easily causes pneumoconiosis; The worker of height powder (coal) dirt operation place work, sight line is easily stopped, in operation, easily causes personal injury accidents; The harm of its maximum is also that coal dust has explosivity, in suitable environment, easily there is dust explosion accident, bring very large threat to the safety in production of mine, therefore all mines have all adopted many measure and methods that prevent dust generation and reduce dust suspension in air, the negative pressure secondary dust settler of installing at work plane is exactly a kind of important depositing dust means, and the correct installation of negative pressure secondary dust settler and use have important practical significance to operating personnel's direct harm for reducing dust.

When negative pressure secondary dust settler is installed, as shown in Figure 1, the two ends, left and right of negative pressure secondary dust settler body 1 are welded with respectively wears rod 2, the rod 2 of wearing at the two ends, left and right of negative pressure secondary dust settler passes respectively interior plate 3 and the outer panel 4 of the lateral wall of the shell that is welded on coal mining unit Rocker arm-motor, wearing rod 2 the part in interior plate 3 and outer panel 4 and interior plate 3 and outer panel 4 welds together, negative pressure secondary dust settler is just fixed on coal mining unit like this, but because the shell of coal mining unit Rocker arm-motor is skewed, spraying spray for negative pressure secondary dust settler during installation can cover full cylinder, outer panel generally will lengthen, if it is bad therefore to run into face roof, cause too low or the frame stretch-forward beam of support with coal mining unit apart from too near, during coal mining, negative pressure secondary dust settler on coal mining unit is easy to collide with the oil cylinder of a frame stretch-forward beam, directly will damage negative pressure secondary dust settler or the fixing outer panel of negative pressure secondary dust settler, and then affect the effect of depositing dust, in addition the ground coal of bulk also easily immediate roof in the bottom of negative pressure secondary dust settler, through extruding, also can damage negative pressure secondary dust settler or the fixing outer panel of negative pressure secondary dust settler, caused the normal use that negative pressure secondary dust settler can not all the period of time, affect the effect of depositing dust, the pad of the shell of interior plate and outer panel and unit Rocker arm-motor is all weak spot with the pad of wearing rod and interior plate and outer panel simultaneously, also cause the unstable of negative pressure secondary dust settler installation.

Summary of the invention

The utility model, in order to solve the easy impaired problem of the negative pressure secondary dust settler being fixed on coal mining unit, provides a kind of crashproof negative pressure secondary dust settler.

The utility model is to adopt following technical scheme to realize: crashproof negative pressure secondary dust settler, comprise negative pressure secondary dust settler body, and on the corner, bottom surface of negative pressure secondary dust settler body, be fixed with magnet.

The negative pressure secondary dust settler body that is fixed with magnet can directly be adsorbed on coal mining unit, absorption position is the center of circle for take coal mining unit cutterhead, cutterhead is to the optional position in the region that the rear 20cm of Rocker arm-motor is radius, the spraying spray that has guaranteed negative pressure secondary dust settler can cover full cutterhead, it is larger that negative pressure secondary dust settler adsorbs fixing region, needn't be confined to mine on the shell of unit Rocker arm-motor, so just be not subject to the impact of support height, the oil cylinder of forestope between encountering, be not subject to the impact of bulk ground coal yet, and fixedly negative pressure secondary dust settler is simple and convenient, without electric welding, also need not process in addition standing finish, maintenance, it is also easy to dismantle, extend normal service time.

Above-mentioned crashproof negative pressure secondary dust settler, is also fixed with on the corner, bottom surface of negative pressure secondary dust settler body magnet cover solid magnet frame inside.Magnet belongs to brittle prod, and frangible fearness is touched, Gu magnet frame can be protected magnet.

Above-mentioned crashproof negative pressure secondary dust settler, Gu magnet frame inner surface and magnet sidewall spacers are 3mm, Gu magnet frame end face is higher than magnet end face 1mm.Guaranteed that like this magnet is not collided with, and does not affect again the attraction of magnet.

Above-mentioned crashproof negative pressure secondary dust settler, on the corner, bottom surface of negative pressure secondary dust settler body, the position of fixed magnet is also fixed with solid rod, and solid rod inserts in magnet, has increased the stability of magnet.

The beneficial effects of the utility model are:

1, succeeding in developing of negative pressure secondary dust settler Novel fixing device, has greatly simplified the installation steps of negative pressure secondary dust settler, has reduced installation exercise personnel's working strength.

2, the mounting seat due to the negative pressure secondary depositing dust using in the past is all welded on unit Rocker arm-motor outer wall.Once touch off or damage, just must must employ electric welding measure and make up.And employ at mining face under mine the probability that electric welding meeting increases accident potential, to safety in production, can cause certain influence.And this Novel fixing device is after scene manufacture, one-shot forming, not bad when long, avoided the danger of down-hole electric welding.

3, to also have a maximum feature be exactly the do not mined restriction of unit model of fixed location to this device, can be freely at cutterhead, to the radius of 20cm plane after rocking arm, arbitrarily installs.

4, another feature of this device is flexible anti-touching.Firm banking used is owing to being welded on unit outer wall before this, once encounter, coarse coal is pounded or surprisingly scrape Zeng with support, owing to being very stiff and demanding, so atomization mechanism and base very easily damage.And present used high-strength magnetic ferropexy base is fixedly to lean on the superpower suction of strong magnetic to complete, encounter breaking or scraping after Zeng with the accident of support of coarse coal, only can pound to move or touch and move negative pressure secondary dust settler, later, the operating personnel of work plane only need put sprayer pushed home.
