Abstract
The utility model discloses a dual-chamber separation type negative pressure dustproof hood, which is characterized in that the two sides of a bulk material conveying belt are provided with dustproof hoods fixed on brackets of a grate discharging chute; the dustproof hood is composed of an inner side baffle and an outer side baffle; a dual-chamber separation balance plate is arranged between the inner side baffle and the outer side baffle; the lower parts of the inner side baffle and the outer side baffle are provided with negative-pressure chamber sealing plates so that a negative-pressure chamber is formed between the two baffles; the negative-pressure chamber sealing plates contact the bulk material conveying belt; and a rectangular cover plate of the dustproof hood is provided with a flexible equalizing device whose cross section is trapezoidal and lower part is strip-shaped. The utility model has the advantages that induced air volume of a positive-pressure chamber inside the hood is small when blanking material, the shock waves of the blanked material are light, the equipment can be avoided being damage, the negative pressure inside the negative-pressure chamber is even, and the dust does not escape with characteristics of reasonable and simple structure, safe and reliable operation and high dustproof and dust removing efficiency.
Description
Technical field
The utility model belongs to bulk cargo and transmits equipment technology field of transport, relates in particular to the isolated negative pressure dust boot of a kind of two-chamber.
Background technology
Along with country pays much attention to the environmental protection of worker's working space, can the room air dust-laden up to standard, and dust boot is a key equipment.The bulk cargo transfer designs was not considered dustproof problem in the past, only guaranteeing that bulk cargo falls at transfer point does not scatter on the ground just, cause the part dust-contained airflow from cover mouthful directly ejection, pollute room air, the utility model is to design on the basis of having analyzed the existing problem of this dustproof facilities, solve bulk cargo and carried the more existing problems of transfer point dustproof facilities, indoor no dust is leaked, thereby when being a kind of blanking in the cover malleation chamber induce air quantity little, the blanking shock wave is light, the negative pressure cavity negative pressure is even, and dust does not have the dust boot of the desirable bulk cargo belt conveyor transfer point that escapes.
Summary of the invention
The purpose of this utility model be to improve the deficiency of prior art and when a kind of blanking is provided in the cover malleation chamber induce that air quantity is little, the blanking shock wave light, avoid that equipment breaks, the negative pressure cavity negative pressure evenly, dust do not have escape, the isolated negative pressure dust boot of two-chamber simple, safe and reliable to operation, dustproof, that efficiency of dust collection is high rational in infrastructure.
The purpose of this utility model is to realize like this, the isolated negative pressure dust boot of a kind of two-chamber, be by the bulk cargo belt conveyor, be provided with the dustproof cover body that is fixed on the deflector chute support in bulk cargo belt conveyor both sides, dustproof cover body top opening part is provided with cover plate, dustproof cover body is made up of interior side shield and outside baffle plate, be provided with two-chamber between interior side shield and outer side shield and isolate balance plate, the bottom of interior side shield and outer side shield is provided with the negative pressure cavity closing plate and makes between two baffle plates and form negative pressure cavity, dustproof cover body contacts with the bulk cargo belt conveyor by the negative pressure cavity closing plate, be characterized in that being provided with the cross section on dust boot rectangle cover plate is trapezoidal equalizing device, equalizing device adopts flexible material, and the bottom of equalizing device is a strip.
In order further to realize the utility model purpose, can be the cross section that trapezoidal equalizing device seals whole conveying bulk cargo top dust boot.
In order further to realize the utility model purpose, can be that the cross section of interior side shield and outer side shield is trapezoidal cover degree of lip-rounding shape.
In order further to realize the utility model purpose, can be that interior side shield all becomes 50 °-80 ° to slope inwardly with outer side shield with horizontal surface.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model adopts and be provided with the cross section on dust boot rectangle cover plate is trapezoidal equalizing device, equalizing device adopts flexible material, the bottom of equalizing device is a strip, when carrying, higher bulk cargo bump is all pressed equipment, equalizing device is under the pressure of bulk cargo, and the strip of bottom separately makes bulk material leveling, be unlikely to break equipment, during blanking in the cover malleation chamber induce air quantity little, the blanking shock wave is light, not during blanking, shrink the equalizing device bottom, the interior negative pressure of negative pressure cavity is even when handling dust, does not have local zone of positive pressure, and dust does not have the phenomenon of escaping; The cross section of interior side shield and outer side shield is trapezoidal cover degree of lip-rounding shape, is convenient to sealing and forms negative pressure cavity; The utlity model has rational in infrastructure simply, safe and reliable to operation, the later maintenance amount is little, small investment, the characteristics dustproof, that efficiency of dust collection is high.
