The air curtain spraying device comprises a box body, spraying holes are uniformly formed in the box body, one side of the box body is provided with an air inlet, the box body is square, and the upper end and the lower end of the box body are in round corner transition. The air curtain spraying device is of a box body structure on the whole, the spraying holes are uniformly formed in the box body, uniform pressure can be guaranteed when compressed air passes through the spraying holes, the defect of an existing spiral-tube-shaped air curtain spraying device is overcome and safety of operators is better guaranteed.
Description
Technical field
The utility model relates to the air curtain spray equipment, belongs to survival capsule sprinkling equipment technical field.
Background technology
Mining survival capsule need not the outside resources supply; the miner that can't in time withdraw when protection mine disaster takes place is not subjected to harm such as gas and dust explosion, toxic and harmful intrusion and oxygen shortage; the existence support facility that inside provides is for the ground first-aid personnel wins long rescue time.The air curtain spray equipment is the important component part of survival capsule, is compressed air is formed air curtain by jet air curtain tube, forms an isolated relatively confined chamber at the protective door place, can effectively solve entering of toxic and harmful, guarantees personnel's safety.Existing air curtain spray equipment is shape in the shape of a spiral mostly, has aperture and spray on helix tube, and this structure can cause the air pressure inequality, and external pressure causes spray uneven greater than central pressure at last, brings very large hidden danger for people's life security.
Summary of the invention
The purpose of this utility model is to solve the weak point that above-mentioned prior art exists, and a kind of reasonable in design, even, the uniform air curtain spray equipment of sprinkling of air pressure are provided.
The utility model is achieved through the following technical solutions:
The air curtain spray equipment, its special character is to comprise box body 1, evenly is provided with spray apertures 2 on the box body 1, and box body 1 one sides have air inlet port 3, and box body 1 is square box body, the round-corner transition of two ends up and down of box body 1.
Air curtain spray equipment of the present utility model, integral body is box body structure, and on box body, evenly be provided with spray apertures, compressed air can guarantee that pressure is even after by spray apertures like this, solve the weak point of the air curtain spray equipment existence of existing helix, guaranteed personnel's safety more.
Description of drawings
Fig. 1: air curtain spray equipment structural representation of the present utility model;
The lateral view of Fig. 2: Fig. 1;
Among the figure: 1, box body, 2, spray apertures, 3, air inlet port.
The specific embodiment
Provide the specific embodiment of the present utility model below with reference to accompanying drawing, be used for formation of the present utility model is described in further detail.
The air curtain spray equipment of present embodiment comprises box body 1, evenly is provided with spray apertures 2 on the box body 1, and box body 1 one sides have air inlet port 3, and box body 1 is square box body, the round-corner transition of two ends up and down of box body 1.
The air curtain spray equipment of present embodiment, integral body is box body structure, and evenly is provided with spray apertures on box body, and compressed air can guarantee that pressure is even after by spray apertures like this, solve the weak point of the air curtain spray equipment existence of existing helix, guaranteed personnel's safety more.
The unspecified content of the utility model is prior art, and those skilled in the art can obtain to inspire from present embodiment and prior art, is out of shape to obtain other embodiment.Therefore, protection domain of the present utility model should be determined according to the protection domain of claim.
