Abstract
The utility model discloses a dustproof air curtain device which comprises an air blower (1), an air supply pipe (2) and an air collecting bin (3). The air blower (1) is communicated with the air collecting bin (3) through the air supply pipe (2), and the air collecting bin (3) is provided with one or more rows of air outlet holes (4). Compared with a traditional technique, an air curtain formed when the air curtain device works can effectively limit dust within a certain range, the dust is effectively controlled, work environment of workers is effectively improved, and the danger that a large amount of the dust is accumulated and accordingly explosions occur is avoided.
Description
Technical field
The utility model relates to a kind of dustproof air curtain device, belongs to the powder material handling field in field of Environment Protection.
Background technology
In field of Environment Protection, some granular materials need to be stored in material pot, and powder material generally loads and transports by ton packaging bag, in drawing off material, the as easy as rolling off a log generation dust raising phenomenon of granular material, as everyone knows, airborne dust not only causes serious harm to workman's health, and makes on-site seriously polluted, even can bring threat to the normal operation of some equipment, if dust can not get effective processing, running into static may have the danger of blasting, and workman's life security is threatened.Therefore, research and develop a kind of device that dust can be limited in to certain space necessary.
Utility model content
The purpose of this utility model is to provide a kind of dustproof air curtain device, the dust that this dustproof air curtain device can be have effectively swung when drawing off powder material is enclosed in certain region, improved workman working environment, reduced the harm of dust to other equipment, avoided gathering because of a large amount of dust the generation of the accident of the blast causing.
The technical solution of the utility model: a kind of dustproof air curtain device, comprise air-blast device, air feed pipe and gas collection storehouse, air-blast device is connected with gas collection storehouse by air feed pipe, gas collection storehouse is provided with a row or the above air gate of a row, regulate airshed by rotating speed or the power of selecting or regulate air-blast device, the air-flow that air-blast device bloats can enter gas collection storehouse by air feed pipe, and air curtain wall be discharged and be formed to air-flow can by air gate.
In aforesaid dustproof air curtain device, the air-flow velocity that air gate is discharged air is 0.5～0.8m/s, in the speed range of this air current flow, can effectively prevent passing of dust, also can not make staff pass this air curtain wall and produce uncomfortable sensation simultaneously.
In aforesaid dustproof air curtain device, gas collection storehouse is provided with two discharge pores, and the air of discharging from air gate can form one deck air curtain wall, and dust is controlled in certain space.
In aforesaid dustproof air curtain device, gas collection storehouse is provided with two discharge pores, and the air of discharging from air gate can form two-layer air curtain wall, has increased the thickness of air curtain wall, has improved the sealing effect of air curtain wall.
In aforesaid dustproof air curtain device, gas collection storehouse is provided with three discharge pores, and the air of discharging from air gate can form three layers of air curtain wall.
Compared with conventional art, the air curtain wall that the utility model forms in the time of its work is limited in dust in certain scope effectively, dust is effectively controlled, has improved dramatically workman's working environment, avoided assembling because airborne dust is a large amount of the danger of blasting.
Brief description of the drawings
Fig. 1 is the work schematic diagram of dustproof air curtain device.
Being labeled as in accompanying drawing: 1-air-blast device, 2-air feed pipe, 3-gas collection storehouse, 4-air gate.
