Detailed Description

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. The use of "first," "second," and similar terms in the present application do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

To maintain the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known components of the utility model have been omitted.

As shown in fig. 1-2, a portable drilling air jet dust remover comprises a first cylinder 4, a second cylinder 3, a third cylinder 1 and a fourth cylinder 2 which are arranged from left to right in sequence; the left end opening of the second barrel 3 is sealed and concentrically fixed at the right end opening of the first barrel 4, the right end opening of the second barrel 3 is sealed and concentrically fixed at the left end opening of the third barrel 1, the left end opening of the fourth barrel 2 is sealed and concentrically fixed at the right end opening of the third barrel 1, the left end opening of the first barrel 4 is also sealed and inserted with an air outlet 5, the right end opening of the fourth barrel 2 is also sealed and inserted with a dust inlet 6 which is obliquely and upwards arranged, and the bottom of the first barrel 4 is also sealed and inserted with a sewage outlet 11; still be equipped with impeller 10 in the second barrel 3, the upside of fourth barrel 2 is still pegged graft and is had intake pipe 7 and the inlet tube 8 of vertical setting, still is fixed with amortization cotton 9 on the inner wall of third barrel 1, and the inside nozzle stub 13 that still is equipped with transverse distribution of the right-hand member opening part of amortization cotton 9, and the left end opening part of nozzle stub 13 still is fixed with shower nozzle 14, and the right-hand member of nozzle stub 13 still links to each other with the inner of intake pipe 7 through elbow 12.

A first cone-shaped opening portion 92 is formed inside the opening at the left end of the silencing cotton cylinder 9, a second cone-shaped opening portion 93 is formed inside the opening at the right end of the silencing cotton cylinder 9, and a straight cylinder section 91 is formed between the first cone-shaped opening portion 92 and the inner end of the second cone-shaped opening portion 93.

The short pipe 13 and the shower head 14 are concentrically provided in the second tapered mouth portion 93.

The outer end of the air inlet pipe 7 is also connected with a first valve 15 in series, and the outer end of the water inlet pipe 8 is also connected with a second valve 16 in series.

When the dust collector is used, the dust conveying pipeline is connected into the dust inlet 6, dust generated by punching is introduced into the fourth cylinder 2 through the dust conveying pipeline and the dust inlet 6, the second valve 16 is opened to introduce water into the fourth cylinder 2 so as to be mixed with the dust, the first valve 15 is opened to introduce air under pressure into the spray head 14 through the air inlet pipe 7, the elbow 12 and the short pipe 13, and then the spray head 14 sprays the dust leftwards, so that the dust is driven to flow leftwards, and the water and the dust are fully mixed.

The flow of the mixed gas in the silencing cotton cylinder 9 can effectively eliminate noise, and meanwhile, the design of the first cone-shaped part 92, the straight cylinder section 91 and the second cone-shaped part 93 enables the mixed gas to form gas jet flow in the silencing cotton cylinder 9 so as to greatly accelerate the flow speed.

The mixed gas flows into the second cylinder 3 after coming out from the left end of the silencing cotton cylinder 9, then passes through the impeller 10 to separate the dust after moisture absorption from the gas and falls to the bottom of the first cylinder 4, and finally is discharged outwards through the sewage outlet 11.

The utility model has compact and light structure, low cost, simple and convenient use and can work without power connection; in addition, the weight is light, so that the movement and the transportation are convenient; therefore, the dust remover has strong adaptability, and can be used in various orifice dust removing occasions and various dust producing devices such as a shotcrete machine, a bolting machine, a stirring machine and the like.
