In the figure: the dust collecting cover 1, the dust collecting cavity 11, the air inlet channel 12, the dust recovery pipe 2, the air curtain dustproof device 3, the air inlet pipe 31, the communicating pipe 32, the air curtain bottom ring 33, the jet hole 34, the backflow bottom cover 4 and the equipment mounting flange 41.

Detailed Description

The present invention will be further described with reference to the following drawings and detailed description, wherein the descriptions of "left", "right", etc. refer to fig. 1 for reference:

as shown in figures 1-3, a dust material absorbing, recovering and escape-proof system comprises a dust receiving cover 1 and a backflow bottom cover 4, wherein the dust receiving cover 1 is covered on the top of a screening device, the backflow bottom cover 4 is installed on the bottom of the screening device, a dust receiving cavity 11 is arranged in the dust receiving cover 1, a dust recovery pipe 2 is connected to the dust receiving cover 1, the dust recovery pipe 2 is communicated with the dust receiving cavity 11, the dust recovery pipe 2 is connected with an external dust collection and recovery device, the dust raised on the screening device is collected in a centralized manner, an air curtain dust prevention device 3 is installed on the dust receiving cover 1, the air curtain dust prevention device 3 can generate an air curtain covering the screening device to prevent the dust from escaping into a workshop to form pollution, the backflow bottom cover 4 is arranged at a position right below the dust receiving cover 1, the air curtain and the backflow bottom cover 4 form a complete sealed environment, the dust diffusion phenomenon of the material can be effectively prevented by ensuring that the dust does not escape, the problem of overhigh density of the dust in a screening room is solved, and the health of operators can be effectively protected.

Cover 1 lateral wall is accomodate to the dust is hollow structure, form inlet channel 12 in the dust is accomodate cover 1 lateral wall, gas curtain dust keeper 3 includes intake pipe 31, a plurality of intake pipe 31 are connected on cover 1 is accomodate to the dust, intake pipe 31 all is linked together with inlet channel 12, intake pipe 31 is linked together with external air supply, it forms required air to provide the gas curtain, a plurality of intake pipe 31 are according to the angle equipartition, be connected with communicating pipe 32 between the adjacent intake pipe 31, the air input of each position in the inlet channel 12 can be balanced like this, form the gas curtain that all the flow is stable in each position, cover 1 bottom is accomodate to the dust is connected with round gas curtain bottom ring 33, the effect of gas curtain bottom ring 33 as inlet channel 12 bottom shrouding, set up the jet orifice 34 of two rings of inside and outside distributions on the gas curtain bottom ring 33, form two gas curtain layers through two rings of jet orifice 34.
