Abstract

The utility model discloses an aperture deduster for drilling, and the deduster consists of a dust collector, a jet pipe, a dust return pipe, and a high-pressure water pump. The dust collector consists of a sealing cover, a negative pressure cavity, and a spraying cavity. The bottom of the negative pressure cavity is additionally provided with a dust exhaust hole. The outer surface of the top of the spraying cavity is provided with a water inlet, and the interior of the spraying cavity is provided with a sprayer head which is communicated with the water inlet. Spraying holes are uniformly distributed on the lower surface of the sprayer head. The bottom of the spraying cavity is provided with at least one water return hole. The water inlet is communicated with the high-pressure water pump through an upper water pipe. The water return hole is communicated with a liquid return mouth through a water return pipe. One end of the water return pipe is communicated with the dust exhaust hole, and the other end of the water return pipe is communicated with a dust return mouth. The deduster provided by the utility model can effectively collect the dust floating in the air, and can effectively clear the dust in a drilling rod, thereby greatly improving the work efficiency of the deduster, and reducing the pollution from dust.

Description

Probing orifice dust catcher

Technical field

This novel probing orifice dust catcher that relates to, belongs to drilling equipment field.

Background technology

At present, in the operation such as coal production, constructing tunnel, often need to carry out bore operation, rig at work, can produce a large amount of dust pollutions, and serious threat constructor's is healthy.In order to overcome this problem, develop at present multiple cleaner, the wherein axial line of the dust-collecting pipe of conventional deduster and the axial line of dust arrester is vertical is connected, dust is easily discharged from the drilling rod hole of both sides before and after dust arrester, can not thoroughly solve the problem that dust leaks.Also the deduster having is provided with sealing shroud at the drilling rod hole place of the rear side dust arrester of dust arrester, but the frictional force between sealing shroud and the drilling rod of High Rotation Speed is larger, will soon produce larger gap, keeps away leaking of unavoidable dust.

Summary of the invention

This novel object is just to overcome above-mentioned deficiency, and a kind of probing orifice dust catcher is provided.

For achieving the above object, originally novel is to be achieved through the following technical solutions:

Probing orifice dust catcher, by dust arrester, jet pipe, dust return pipe and high-pressure hydraulic pump form, described jet pipe front end is established adpting flange, at least one sprays the mouth of a river end, one is returned dirt mouth and a liquid return hole, its bottom outer wall is symmetrical arranged at least one group of fixed flat planar, described high-pressure hydraulic pump is by water pipe and injection mouth of a river UNICOM, described dust arrester is by seal disc, air pressure negative pressure cavity and spray chamber form, described air pressure negative pressure cavity and spray chamber are integral type structure, between air pressure negative pressure cavity and spray chamber, establish dividing plate, wherein air pressure negative pressure cavity is arranged on seal disc upper surface, and contact surface place establishes sealing ring, seal disc soffit is separately established seal sleeve, described seal sleeve and seal disc integral structure, described air pressure negative pressure cavity, dividing plate, spray chamber and seal disc are coaxial, and axis place arranges drilling rod hole, another uniform at least four fixing threaded holes on seal disc, dust exhausting hole is separately established in described air pressure negative pressure cavity bottom, described spray top of chamber external surface is established inlet opening, shower nozzle and inlet opening UNICOM are established in inside, described shower nozzle is truncated cone-shaped structure, the uniform mouth spray of soffit, at least one backwater hole is established in described bottom, spray chamber, described inlet opening is by upper hose and high-pressure hydraulic pump UNICOM, backwater hole is by return pipe and liquid return hole UNICOM, described dust return pipe one end and dust exhausting hole UNICOM, the other end and Hui Chenkou UNICOM.

This new structure is simple, easy to use, can effectively collect the skyborne dust that suspends, and the dust that also can take out of drilling rod self is effectively cleared up, thereby has improved greatly the task performance of deduster, has reduced dust pollution.
