Abstract
The utility model provides a dog -house adjustable dust cage, including hollow dust collection compartment, flexible sealing curtain, air outlet, dog -house around, side seal curtain, raise dust source, hollow dust collection compartment bottom is fixed with the flexible sealing curtain, two parallel arrangement's hollow dust collection compartment around with the side seal curtain constitute airtight cavity all around, constitute the dog -house between two hollow dust collection compartment, its characterized in that: hollow dust collection compartment bottom is equipped with the air outlet, and the air outlet is located the outside of flexible sealing curtain, and every hollow dust collection compartment top is extended the face and all is equipped with the board of becalming with the inside wall junction, and hollow dust collection compartment inside wall is equipped with the inlet scoop, and the inlet scoop is located hollow dust collection compartment inside wall tip. The utility model discloses the device has been solved fresh air and dust -loaded air and has been accounted for the problem that compares, and control cement bag's the regional area of bag that falls reduces the air inlet area of inlet scoop, reduces fresh air accounting for in the dust cage body and compares, makes more dust -loaded air entering dust cage body, has improved the entrapment raise dust efficiency of dust cage.
Description
Technical field
The utility model relates to dust collecting technique field, the dust gathering arrester that especially a kind of dog-house is adjustable.
Background technology
In bagged cement entrucking process, bag of cement enters in compartment can produce dust from flying, neat in order to be piled up onboard by bag of cement, needs the adjustment of entrucking workman scene.Therefore airborne dust region can not be closed completely, make entrucking workman be in dust surround in, in order to improve the operating environment of workman, must will during entrucking particularly bag of cement fall time produce airborne dust trapping concentrate after-purification process.Existing capture method is generally arrange a gas skirt above airborne dust point, is solved by negative-pressure air-suction.On the one hand, easy to operate in order to workman, gas skirt aperture area is less, only accounts for the sub-fraction in airborne dust region, and dust gathering arrester position is higher, from airborne dust point distance more than 1.5 meters, most of airborne dust cannot be trapped, improve arresting efficiency, just must strengthen suction air volume, increase cost.On the other hand because dusty gas needs the facial breathing area through operator, the operating environment of workman cannot be improved.
For the deficiency of existing dust gathering arrester described above, with regard to the operation principle of dust gathering arrester, increase the overlay area of dust gathering arrester, shorten the distance of airborne dust point and inlet scoop, avoid dusty gas to flow through workman's face breathing area and gas-solid ratio, effectively can make up the deficiencies in the prior art.
Utility model content
The purpose of this utility model is the problems referred to above existed for existing technology, provide the dust gathering arrester that a kind of dog-house is adjustable, the utility model device solves the problem of fresh air and dust laden air accounting, control the region area that pockets of bag of cement, reduce the incoming air area of inlet scoop, reduce the accounting of fresh air in dust gathering arrester body, more dust laden airs are entered in dust gathering arrester body, improves the trapping airborne dust efficiency of dust gathering arrester.
For this reason, the technical solution that the utility model is taked is:
The dust gathering arrester that a kind of dog-house is adjustable, comprise hollow dust-collecting cavity, flexible sealing curtain, air outlet, dog-house, front and back side seal curtain, airborne dust source, flexible sealing curtain is fixed with bottom hollow dust-collecting cavity, two hollow dust-collecting cavities be arranged in parallel and front and back side seal curtain form surrounding airtight cavity, dog-house is formed between two hollow dust-collecting cavities, air outlet is provided with bottom hollow dust-collecting cavity, air outlet is positioned at the outside of flexible sealing curtain, each hollow dust-collecting cavity top extended surface and madial wall junction are equipped with plate of becalming, hollow dust-collecting cavity madial wall is provided with inlet scoop, inlet scoop is positioned at hollow dust-collecting cavity madial wall end.
As further preferably, described in becalm plate and described hollow dust-collecting cavity junction be provided with active page.
As further preferably, described in becalm plate and described hollow dust-collecting cavity madial wall angle be 45 ° ~ 90 °.
As further preferably, described in becalm plate and described hollow dust-collecting cavity madial wall angle be 90 °.
As preferred further, the spacing of plate end of becalming described in two is 150cm ~ 240cm.
The beneficial effect of technique scheme is:
The utility model device is provided with plate of becalming, the bore of dog-house can be regulated, when not affecting operation, decrease the area of dog-house, dust laden air dead angle is formed below becalm plate and inlet scoop, the area size at dust laden air dead angle can be regulated by becalm plate and hollow dust-collecting cavity inwall angle, fresh air reduces in dust laden air accounting, decrease dust laden air total amount, improve the arresting efficiency in airborne dust source, flexible sealing curtain and front and back side seal curtain ensure that the sealing of hollow dust-collecting cavity, decrease the air capacity that the external world brings into, thus decrease the total air needing purification, reduce costs.

In figure: 1, hollow dust-collecting cavity; 2, flexible sealing curtain; 3, to becalm plate; 4, air outlet; 5, dog-house; 6, front and back side seal curtain; 7, airborne dust source; 101, inlet scoop; 301, active page.
Detailed description of the invention
For making feature of the present utility model and advantage clearly, be described below in conjunction with specific embodiment.
As shown in Figure 1, the dust gathering arrester that a kind of dog-house is adjustable, comprise hollow dust-collecting cavity 1, flexible sealing curtain 2, air outlet 4, dog-house 5, front and back side seal curtain 6, airborne dust source 7, flexible sealing curtain 2 is fixed with bottom hollow dust-collecting cavity 1, two hollow dust-collecting cavities be arranged in parallel 1 form surrounding airtight cavity with front and back side seal curtain 6, dog-house 5 is formed between two hollow dust-collecting cavities 1, air outlet 4 is provided with bottom hollow dust-collecting cavity 1, air outlet 4 is positioned at the outside of flexible sealing curtain 2, each hollow dust-collecting cavity 1 top extended surface and madial wall junction are equipped with plate 3 of becalming, hollow dust-collecting cavity 1 madial wall is provided with inlet scoop 101, inlet scoop 101 is positioned at hollow dust-collecting cavity 1 madial wall end.
In this example, described plate 3 of becalming is provided with active page 301 with described hollow dust-collecting cavity 1 junction, can be controlled to becalm the opening angle of plate 3, described plate 3 of becalming is 45 ° ~ 90 ° with described hollow dust-collecting cavity 1 madial wall angle, described plate 3 of becalming is preferably 90 ° with described hollow dust-collecting cavity 1 madial wall angle, now the footpath mouth of dog-house 5 is minimum, and the spacing of plate 3 end of becalming described in two is 150cm ~ 240cm, makes bag of cement have enough jettisoning space and operating personnel to carry space.
