The specific embodiment

For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.

Fig. 1 is foam dust-removing device embodiment one front view of the present invention, and Fig. 2 is foam dust-removing device embodiment one right view of the present invention.As depicted in figs. 1 and 2, present embodiment provides a kind of foam dust-removing device, comprising: blowing agent fluid reservoir 1, at least one spray gun 2 and first pressure ventilation pipe 3.

But blowing agent fluid reservoir 1 top is provided with the liquid injection port 11 of switch, and blowing agent fluid reservoir 1 is used to hold blowing agent 13.Concrete, the dedusting material that present embodiment foam dust-removing device uses is a blowing agent 13, and holds blowing agent 13 by blowing agent fluid reservoir 1.

The corresponding liquid outlet of offering 12 with the top of blowing agent fluid reservoir 1 of the inlet 21 of spray gun 2 connects, and is provided with the foam screen 4 that is used to produce bubble between the inlet 21 of spray gun 2 and the liquid outlet 12 of blowing agent fluid reservoir 1; Enter into of spout 22 ejaculations of the blowing agent 13 of spray gun 2 from the inlet 21 of spray gun 2 by spray gun 2.Concrete, the blowing agent 13 in the present embodiment becomes foam through behind the foam screen, and foam is ejected in the external environment condition by the spout 22 of spray gun 2, thereby by the dust in the foam absorbed air.

First pressure ventilation pipe 3 is installed on the blowing agent fluid reservoir 1, and the air outlet 31 of first pressure ventilation pipe 3 is positioned at the bottom of the cavity of blowing agent fluid reservoir 1, and the air intake 32 of first pressure ventilation pipe 3 is used to provide the pressure wind regime (not shown) of pressure wind to be connected with outside.Concrete, the pressure wind that first pressure ventilation pipe 3 will press wind regime to produce is injected into the bottom of blowing agent fluid reservoir 1, blowing agent 13 forms bubble under the pressure wind action, the increasing gradually of bubble makes blowing agent 13 arrive liquid outlet 12 positions of blowing agent fluid reservoirs 1, blowing agent 13 becomes foam after by foam screen 4, and the spout 22 from spray gun 2 penetrates under the wind action pressing.

Below in conjunction with Fig. 1 and Fig. 2 the course of work of present embodiment foam dust-removing device is described.At first,, in blowing agent fluid reservoir 1, inject blowing agent 13, after treating to inject enough blowing agents 13 in the blowing agent fluid reservoir 1, liquid injection port 11 is closed by liquid injection port 11 by opening liquid injection port 11; Then, the pressure wind that will press wind regime to produce by the air intake 31 of first pressure ventilation pipe 3 is injected in the blowing agent fluid reservoir 1, presses wind to emerge from blowing agent 13, thereby produces the bubble that a large amount of blowing agents 13 form, and bubble increases gradually to liquid outlet 12 is covered; The blowing agent 13 that is in liquid outlet 12 positions passes foam screen 4 under the pressure wind action, make blowing agent 13 become foam, and be ejected in the air with the spout 22 of pressing wind through spray gun 2, thereby the dust in the absorbed air reaches the effect of dedusting.
