Abstract
The invention relates to an arc fan nozzle used for reducing dust. The arc fan nozzle comprises a nozzle body with a thread connector, and a flow-guiding body arranged at an outlet of the nozzle body. An inner bore of the nozzle body is divided into an inlet section, a gradient throat section and an outlet section. The flow-guiding body is of a fan-shaped cone, and the height of the fan-shaped cone is of 1-10cm. Dust reducing media at the outlet of the nozzle form into arc fan spray through the flow-guiding body, and drill cutting components such as drills, cutting heads and the like can be preferably wrapped. The diffusing range is wide, and meanwhile, the using quantity of the dust reducing media can be reduced so as to greatly improve the utilizing rate of the dust reducing media. The arc fan nozzle not only can be used for the dust prevention of drills, cutting heads and the like in the drilling and cutting operations, but also can be used on other occasions where the arc fan nozzle is needed. The arc fan nozzle has the advantages of simple structure, uniform spray, small flow quantity, high impact force, high medium utilizing rate and wide practical applicability.
Description
Technical field
The present invention relates to the arc fan nozzle for depositing dust, be particularly useful for the dust prevention and control that the dirt operating location is produced in drill bit, cutting head of roadheader, coal mining machine roller, transfer point, coal bunker, stone pit etc.
Background technology
At industrial circle, dust is to all many-sided harmful effects that produces such as health, production safety, product quality, economic benefit, be the significant problem that country pays close attention to always, particularly produce for the mine, the dust Occupational Disease Hazards is the Focal point and difficult point in the national treating flour dust work especially.In recent years, annual Pneumoconiosis disease reaches 10,000 examples, by the end of the year 2011, and national coal mining enterprise accumulative total Pneumoconiosis Patients 31.2 ten thousand examples, the pneumoconiosis recall rate is up to 7.2%.The expert estimates that 10 years from now on to 15 years China's pneumoconiosis morbidity sums also will be the continuation ascendant trend.
In order to prevent and treat dust, China's industrial circle is taked the technological means such as dust removal by ventilation, atomizing de-dusting.Nozzle is the jet equipment core component for atomizing de-dusting, and at present the flow pattern of common nozzle mainly contains solid-cone, hollow cone, flat fan etc., and wherein first-class to cut nozzle more common in the operation at brill be solid-cone peace fan nozzle at drill bit, cut.These nozzle Main Problems are that water-use efficiency is low, can not fully wrap up the product dirt pits, and in the water yield one regularly, area coverage is little, and then can bring the series of negative problem.Take in the colliery as example: mainly adopt development machine under the coal mine during digging operation, and the cutterhead of development machine is larger, the parcel that generally a large amount of water sprays of needs could be intact with cutterhead, this has just caused water excessive, worsened operating environment, and the calorific capacity that also can cause coal along with increasing of water reduces, and affects the quality of coal.Particularly be the driving face of water imbibition soft rock at some base plate, base plate can cause wet weak falling into dilutional hyponatremia owing to depositing dust, often affects normal mining progress and safety in production.Therefore, in order to improve dustproof water-use efficiency, prevent that dustproof water is excessive, ensure dust-laying effect, be badly in need of the invention new type nozzle.
Summary of the invention
Technical problem: the objective of the invention is for the problem that exists in the prior art, provide a kind of simple in structure, spray evenly, low discharge, high impact forces, range of scatter are wide, the arc fan nozzle that is used for depositing dust.
The present invention is used for the arc fan nozzle of depositing dust, comprises the nozzle body that is threaded connector and the baffle that is located at the exit of nozzle body; Described nozzle body endoporus is divided into entrance, gradual change throat and outlet section, and described baffle is fan-shaped cone, and the height of fan-shaped cone is 1-10cm.
Described nozzle body comprises connector, is provided with the expanding section on the connector, and the baffle that is located at the nozzle body exit is external on the expanding section in nozzle body exit.
Described nozzle body comprises connector, is located at the conduit on the connector, and the baffle that is located at the nozzle body exit is built on the outlet section of guide pipe inner hole, and conduit outlet has the lead angle that forms arc-shaped gaps with baffle.
Beneficial effect: the present invention adopts the baffle of fan-shaped cone, make the depositing dust medium of jet expansion form the spraying of arc fan, can better wrap up drill bit, the first-class brill of cut cuts parts, range of scatter is wide, can reduce again simultaneously depositing dust medium use amount, can improve the area coverage of depositing dust medium (water, the aqueous solution or foam) and the effective rate of utilization of depositing dust medium, reduce the excessive negative issue that brings of water in the depositing dust process.Unite use with a plurality of arc fan nozzles and can form airtight annulus, cylinder or the conical dirt space of producing are realized comprehensively parcel.The fluid passage of this nozzle is large and smooth, has prevented nozzle blockage, and the nozzle atomization amount is large, and is easy to use, safe and reliable, can be used for down-hole and ground etc. and bores dust prevention and control when cutting operation, has greatly improved the utilization rate of depositing dust medium.The present invention not only can be used for drill bit, the first-class dust prevention and control that bores when cutting operation of cut, also can be used for the occasion that other need the arcuation fan nozzle.It is simple in structure, injection is even, low discharge, high impact forces, Utilizing Rate are high, has widely practicality.
