Brief description of the drawings

Fig. 1 is a kind of structural representation of pneumatic type down-hole hammer drilling dust-removing apparatus described in the utility model.

Embodiment

1 the utility model is described in further detail below in conjunction with the accompanying drawings：

Embodiment one

A kind of pneumatic type down-hole hammer drilling dust-removing apparatus of the utility model, including trumpet type dust storage chamber 2, steel pipe 1, scum pipe 6th, front end dust guard 3 and rear end dust guard 5, the front end of steel pipe 1 is fixedly connected with the osculum end of trumpet type dust storage chamber 2, preceding Dust guard 3 is held to be arranged on the wide mouth part of trumpet type dust storage chamber 2, rear end dust collect plant is arranged on the rear end of steel pipe 1, scum pipe 6 It is arranged on the lower section of trumpet type dust storage chamber 2 and the upper end of scum pipe 6 is connected with the inside of trumpet type dust storage chamber 2, front end dust guard 3 It is fitted at drilling orifice, the drilling rod 4 of pneumatic type down-hole hammer is arranged on hole through rear end dust guard 5, steel pipe 1 and scum pipe 6 Intraoral, rear end dust guard 5 is rubber peel, and front end dust guard 3 includes cylindrical rubber bulb stopper and gland, and cylindrical rubber bulb stopper leads to Overpressure cap is fixed on the rear end of steel pipe 1, and scum pipe 6 includes funnel section and straight length, upper end and the trumpet type dust storage chamber 2 of funnel section Inside connection, the lower end of funnel section is fixedly connected with the upper end of straight length, a diameter of 100mm of steel pipe 1, steel pipe 1, trumpet type collection The thickness of dirt room 2 and scum pipe 6 is 1mm.

The iron sheet of dust storage chamber 2 is welded, and main function is to collect boring mud and dust that drilling is excluded；Front end dust guard 3 Make and be fixed at the horn mouth of dust storage chamber 2 using waste tire of automobile leather, main function is to make dust arrester horn mouth closeer Fit with cutting aperture palisades, prevent that dust scatters everywhere at aperture；The sealing glueballs of the rear end of steel pipe 1 is cut using cylindrical rubber ball Form and fixed with gland, main function is to prevent dust from being sprayed from the afterbody of dust storage chamber 2；Funnel type scum pipe 6 using iron sheet and Seamless steel pipe 1 splicing more smaller than dust storage chamber 2 is welded, and main function is to exclude boring mud and dust.

The device operation principle is simple, during the drilling of pneumatic type down-hole hammer, and the pressure wind in the input hole of drilling rod 4 will Broken boring mud and dust is spouting by the annular gap of drilling rod 4 and hole wall, in the dust-proof rubber of the horn mouth of dust storage chamber 2 and steel Under the stop of the sealing glueballs of the rear end of pipe 1, exclude that (afterbody of scum pipe 6 connects PVC water and brought to specified row by bottom scum pipe 6 Put a little).

Embodiment two

Dust arrester also includes sparge pipe, and the water side of sparge pipe is arranged at the lower end of scum pipe 6.

It can be passed through press water formation water smoke at the small-bore water pipe of inwall welding-on of scum pipe 6, reach the mesh of direct depositing dust deslagging 's.

Dust arrester should be fixedly secured in aperture in use, prevent dust arrester from significantly swinging, otherwise can shadow The sealing effectiveness of the dust-proof rubber in aperture is rung, causes dust to be leaked from aperture；Dust arrester tail seal rubber abrasion feelings are noted simultaneously Condition, if serious wear, dust is largely leaked, then should change glueballs in time.

Using possessing advantages below after the utility model：

1st, construction time workmen occupational health hazards are substantially reduced, and are reduced due to the occupational disease morbidity that dust pollution is caused Rate.

It is not used before dust arrester, because construction area dust pollution is serious, even if workmen takes anti-dust respirator still Dust is inevitably sucked, while nearby resident can also suffer from this in various degree for construction area, thus triggers pneumoconiosis etc. Dust pollution disease.And such disease is listed in the disease that can not be cured for current medical level.

After dust arrester, because dust is directly discharged by closed conduit, dust pollution is greatly reduced, is constructed Nearby resident's productive life environment is improved for personnel and construction area, so as to prevent or reduce harm of the dust to human body.

2nd, harm of the dust to construction equipments such as rigs is reduced, maintenance of equipment rate is reduced, construction equipment is improved and uses Life-span.

It is not used before dedusting dress, because dust and boring mud under Action of Wind pressure, inject directly on the construction such as rig in hole In equipment, cause the slag input in the case of poorly sealed of some parts of the equipment such as rig to enter dirt, cause construction equipment frequently event Barrier, maintenance rate increase, and leverage the normal operation of the equipment such as rig, so that the maintenance cost of equipment is not only increased, and And directly affects Economic returns and construction period.

After device for reducing dust, it is to avoid the direct harm of dust and boring mud to equipment such as rigs, rig is greatly reduced Deng the breakdown maintenance rate of construction equipment, maintenance cost is reduced, while the construction period is also ensured.

3rd, construction later stage boring mud cleaning up cost is saved.

Be not used dust arrester before, the boring mud splashes discharged in work progress, whole construction area be seen everywhere east one The boring mud of the western a pile of heap, is that later stage site clearing brings no small difficulty, need to put into larger manpower and be responsible for scarfing cinder specially.

After dust arrester, boring mud can be directly discharged to specifying in construction area by the PVC fire hoses of bottom of device Position concentrate stack, it is to be onstructed after the completion of, again property clear up.Thus substantial amounts of human resources can be saved.

The technical solution of the utility model is not limited to the limitation of above-mentioned specific embodiment, every according to skill of the present utility model The technology deformation that art scheme is made, each falls within protection domain of the present utility model.
