Description

A kind of dedusting sealing device for dummy car fixed-point unloading

Technical field

Mobile discharge cleaner is the utility model is related to, more particularly to coordinate with mobile dummy car, transported for bulk cargo The dedusting sealing device of defeated fixed-point unloading.

Background technology

Belt tripper can be realized in transport path on the way flexible discharging, obtained in actual production wide General application, according to production requirement, dummy car can be along the linear discharging of carry out of the optional position of transport way, can also be along defeated Approach fixing point position fixed-point unloading is sent, to suppress the airborne dust in discharge process, deduster is added on usual dump car, but In fixed-point unloading, dummy car needs to come and go operation, the mobile discharge chute and blow tank of dummy car between multiple emptying points Between may move switching sealing fix, be suppress discharge process in airborne dust, anti-leak-stopping dirt, the key link leaked out.

The dust pelletizing system of existing mobile dummy car exposes due to the defects of some structure designs be present in actual use A series of problem is gone out.First, it is contemplated that the absolute altitude of mobile dummy car track inevitably has certain miss when mounted Difference, the error are possible to cause mobile discharge groove to be collided with fixed blow tank when docking, the scheme used at present be Therebetween certain interval is reserved, with the gap come the absolute altitude error of " absorption " track, to ensure that mobile dummy car can be smooth It is current, but the structure makes to fix butt tube and certainly exists certain gap between moving butt tube, causes the two real Now tight docking；Simultaneously as there is error the actual installation position of mobile discharge groove and fixed blow tank with design parameter, And the position stopped every time of mobile discharge groove with design attitude there is also error, therefore, when mobile discharge groove and fixed blow tank In docking, certain radial clearance is certainly existed, to reduce the radial clearance must manually adjust mobile discharge by worker The position of groove, it is troublesome in poeration, discharging progress is influenceed, and manually adjust also to differ and radial clearance is surely completely eliminated, even if disappearing Except radial clearance, axial gap still has, and this make it that dust pelletizing system sucks a large amount of wild wind in the gap location during discharging, causes The larger pressure loss so that air main takes out deficiency in draught to mobile discharge groove, causes dust removing effects bad, has a strong impact on hilllock The operating environment of position worker.

In order to solve the problems, such as that prior art is present, people have carried out long-term exploration, it is proposed that miscellaneous solution Scheme.For example, Chinese patent literature is entitled：(Publication No. CN 101837898A), discloses a kind of mobile dummy car Dedusting airduct docking facilities, including the fixation butt tube being fixed in factory building on air main and be installed on mobile dummy car Mobile at least one of butt tube, described two butt tubes is provided with elastic telescopic section in butt end, and two kinds of butt tubes lead to when docking The elastic telescopic section is crossed mutually to compress and be in close contact, but in the technical program, airborne dust caused by discharging will be through movement Butt tube, fixed butt tube and air main deliver to cleaner after absorbing, and are by mobile butt tube and fixed butt tube Portion is comprehensively aspirated, and to meet the purpose of dedusting, the dust removal method of this kind of comprehensive drawing-in type, energy consumption is big, and extremely easy The less particle of particle in discharge process is sucked into cleaner, larger potential safety hazard, and the equipment of this kind of dedusting be present The discharging of the loose unpacked material of ribbon conveyer progress can not be applicable with method.
