Abstract
The utility model relates to a novel multifunctional dust falling device. The novel multifunctional dust falling device is structurally characterized in that one porthole pipe and one rear-end sealed pipe are respectively installed on the front side and the rear side of a rectangular dust hood provided with a no-spark explosion proof type lining in a splicing or welding mode, and the porthole pipe and the rear-end sealed pipe are made of no-spark explosion proof type materials; the porthole pipe can be inserted into a porthole of a drill hole, and the rear-end sealed pipe is used for penetrating into a drill stem and reducing outward leakage of dust inside the drill hole along the drill stem; and two drainage connectors and two internal spray connectors are arranged at the upper end of the dust hood, and a slag discharge pipe is connected below the dust hood. The novel multifunctional dust falling device has the advantages of being capable of preventing transfinite gas on a working site in the processes of constructing and drilling because of gas emission and reducing drill hole dust hazard, being beneficial for improving underground coal mine working environment, and improving work safety.
Description
Technical field
The utility model relates to a kind of coal production instrument, says more specifically the Multifunction device for reducing dust.
Background technology
During the engineering the drilling such as underground construction spy coal hole, colliery, gas thief hole, gas pumping hole and drawing-off gas hole, adopt wind power slag-discharging can produce a large amount of dust, and very easily cause a large amount of gas to gush out or spray along boring, cause operation field dust and gas density to transfinite, very large to Safety of Coal Mine Production and the healthy harm of personnel.And existing coal mine drilling device for reducing dust only has the function of depositing dust, can't solve the problem of gas, and dust-laying effect is relatively poor.
Summary of the invention
The purpose of this utility model is in order to solve the dust that exists in all kinds of drilling construction processes in colliery and two kinds of adverse factors of gas and custom-designed a kind of Multifunction device for reducing dust simple in structure and easy and simple to handle.
The purpose of this utility model can realize in the following manner: the Multifunction device for reducing dust, side adopts the form of pegging graft or welding that an orifice tube and a rear end sealed tube are installed respectively before and after having the rectangular set dust hood of no-spark explosion-proof type liner, orifice tube and rear end sealed tube all adopt no-spark explosion-proof type material to make, orifice tube can insert in the drilling orifice, the rear end sealed tube is used for penetrating drilling rod and reduces the interior dust of boring along drilling rod to outward leakage, two extraction interfaces and two internal spraying interfaces are installed in the dust gathering arrester upper end, the extraction interface is connected with gas drainage pipeline, the internal spraying interface is connected with pressure water line, and the dust gathering arrester below connects a scum pipe.
The utility model has the following advantages: simple in structure, easy and simple to handle, can satisfy in the various boring procedures of colliery underground construction the requirement that anti-spray orifice transfinites and catches the dirt depositing dust, and greatly improve site work environment and improve field work safe.
