Abstract
The utility model discloses a negative-pressure dust removing device in the field of dust removing equipment, which comprises a shell, an opening provided at the side wall of the shell and connected with a conveyor, a suction fan equipped on the top of the shell, at least one filter bag equipped vertically inside the shell in a way that the top opening of the filter bag is connected with the air inlet of the suction fan, and a back-blow dedusting mechanism provided on the side wall of the shell and comprising an air outlet which is communicated with compressed air and the top opening of the filter bag. When the suction fan is started to exhaust air outwards, a negative pressure is formed inside the conveyor to avoid the overflow of dust. When the dust-containing air flows through the filter bag, the dust is absorbed and attached to the surface of the filter bag. If the filter bag surface is attached with much dust, the dedusting mechanism is actuated to provide high-pressure pulse airflow via the air outlet, to blow off the dust attached to the filter bag into the conveyor. The utility model omits the air net and dust recycle device, prevents the dust overflow during the operation of the conveyor, and reduced the environmental pollution in the working place.
Description
Technical field
The utility model relates to a kind of servicing unit of dust-laden material transfer equipment, particularly a kind of dust arrester.
Background technology
In the prior art, conveying equipment is when carrying the dust-laden material, and is not excessive for guaranteeing the material dust, to reach environmental requirement, conveying equipment moved under negative pressure state.The present method that adopts is that charging aperture, discharging opening or the centre at conveying equipment is provided with the inlet scoop, constitutes the wind net by pipeline and is connected to cleaner; By the air exhauster air draught of deduster back, make to produce negative pressure in the conveying equipment, the material that is sucked away is separated by deduster again, returns conveying equipment; This set is feasible for mini-plant and short distance conveying; Along with the maximization of conveying equipment and long distance transport say just not too reasonable; This can increase complicated wind net design, and can increase investment, and it is stifled to occur material sometimes in the wind net, and deduster can not normally be moved, and conveying equipment can not effectively be moved.
The utility model content
The purpose of this utility model provide can combine with conveying equipment, carry dedusting and make material after separating directly get back to a kind of negative pressure dust removing device of conveying equipment.
The purpose of this utility model is achieved in that a kind of negative pressure dust removing device, comprise housing, the housing side is provided with the opening that can link to each other with conveying equipment, case top is provided with air exhauster, uprightly be provided with at least one filter bag in the described housing, the upper opening of filter bag links to each other with the air inlet of air exhauster; The housing side is provided with reverse gas cleaning mechanism, and reverse gas cleaning mechanism includes one and connects compressed-air actuated gas outlet, and the gas outlet is communicated with the upper opening of filter bag.
During the utility model work, starting air exhauster outwards bleeds, in conveying equipment, form negative pressure, avoided flour dust overflow, when dusty gas flows through filter bag, dust is blocked attached to the filter bag surface through filter bag, pure air is discharged behind filter bag, air exhauster, when the dust on filter bag surface accumulates abundantly, and the deashing mechanism action, blow out high-voltage pulse air-flow blowback filter bag by the gas outlet, make attached to the outer dust of filter bag and fall into conveying equipment; Compared with prior art, the utility model has been saved the retracting device of wind net and particulate dust, guarantees simultaneously effectively the negative pressure of conveying equipment, makes the conveying equipment dust that is in operation not excessive, material after the separation can directly be got back to conveying equipment, has reduced the environmental pollution of workplace.
For guaranteeing that the dust that blowback falls can get back in the conveying equipment smoothly, the housing of described filter bag below is obliquely installed.The inwall of the housing that this is obliquely installed forms one and can make dust fall to feeding back smoothly and send in the device for the plate of the downward trickling of dust.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model fundamental diagram.
The specific embodiment
As figure, be a kind of negative pressure dust removing device, comprise housing 4, the lateral opening 5 of housing 4 can link to each other with conveying equipment 6, and housing 4 tops are provided with air exhauster 1, uprightly are provided with a plurality of filter bags 3 in the housing 4, and the upper opening of filter bag 3 links to each other with the air inlet of air exhauster 1; Housing 4 sides are provided with reverse gas cleaning mechanism 2, and reverse gas cleaning mechanism 2 includes one and connects compressed-air actuated gas outlet 201, and gas outlet 201 is communicated with the upper opening of filter bag 3; The housing 401 of filter bag 3 belows is obliquely installed, can trickle the downwards plate of material of formation.
During work, starting air exhauster 1 outwards bleeds, in conveying equipment 6, form negative pressure, avoided flour dust overflow, when dusty gas flows through filter bag 3, dust is blocked attached to the filter bag surface through filter bag 3, pure air is discharged behind filter bag 3, air exhauster 1, when the dust on filter bag surface accumulates abundantly, the deashing mechanism action blows out high-voltage pulse air-flow blowback filter bag by gas outlet 201, makes attached to the outer dust of filter bag to fall on the inwall of the housing that is obliquely installed, dust trickles downwards, can fall to feeding back smoothly to send in the device.
In the utility model, filter bag can only be provided with one, also can be provided with a plurality of.
Claims (2)
1. negative pressure dust removing device, it is characterized in that: comprise housing, the housing side is provided with the opening that can link to each other with conveying equipment, and case top is provided with air exhauster, uprightly be provided with at least one filter bag in the described housing, the upper opening of filter bag links to each other with the air inlet of air exhauster; The housing side is provided with reverse gas cleaning mechanism, and reverse gas cleaning mechanism includes one and connects compressed-air actuated gas outlet, and the gas outlet is communicated with the upper opening of filter bag.
2. a kind of negative pressure dust removing device according to claim 1 is characterized in that: the housing of described filter bag below is obliquely installed.
