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 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 produces harmful effect to all many-sides such as health, production safety, product quality, economic benefit, the significant problem that country pays close attention to always, particularly for mining production, the Focal point and difficult point of dust Occupational Disease Hazards especially in national treating flour dust work.In recent years, annual Pneumoconiosis disease reaches 10,000 examples, and by the end of the year 2011, national coal mining enterprise will add up Pneumoconiosis Patients 31.2 ten thousand example, and pneumoconiosis recall rate is up to 7.2%.Expert expects 10 years from now on to 15 years China's pneumoconiosis morbidity sums also will in continuation ascendant trend.
In order to prevent and treat dust, China's industrial circle takes the technological means such as dust removal by ventilation, atomizing de-dusting.Be jet equipment core component for nozzle atomizing de-dusting, the flow pattern of nozzle common at present mainly contains solid-cone, hollow cone, flat fan etc., and wherein at drill bit, cut, first-class to cut nozzle more common in operation at brill be solid-cone peace fan nozzle.The subject matter that these nozzles exist is that water-use efficiency is low, can not fully wrap up product dirt pits, and in the water yield one timing, area coverage is little, and then can bring series of negative problem.For colliery: mainly adopt development machine during underground coal mine digging operation, and the cutterhead of development machine is larger, the a large amount of water spray of general needs could by parcel intact for cutterhead, this just causes with water excessive, be degrading operating environment, and the calorific capacity of coal also can be caused to reduce along with increasing of water, affect the quality of coal.Be particularly the driving face of water imbibition soft rock at some base plate, base plate can cause wet weak sunken due to depositing dust dilutional hyponatremia, often affect normal mining progress and safety in production.Therefore, in order to improve dust-proof water-use efficiency, preventing dust-proof water excessive, ensureing dust-laying effect, be badly in need of invention new type nozzle.
Summary of the invention
Technical problem: the object of the invention is for Problems existing in prior art, provide a kind of structure simple, spray evenly, low discharge, high impact forces, range of scatter are wide, for the arc fan nozzle of depositing dust.
The present invention is used for the arc fan nozzle of depositing dust, comprises the baffle in the nozzle body being threaded connector and the exit being located at nozzle body; Described nozzle body endoporus is divided into entrance, gradual change throat and outlet section, and described baffle is quad cone, and the height of quad cone is 1-10cm.
Described nozzle body comprises connector, the expanding section be provided with on connector, and the baffle being located at nozzle body exit is external on the expanding section in nozzle body exit.
Described nozzle body comprises connector, the conduit be located on connector, and the baffle being located at nozzle body exit is built on the outlet section of guide pipe inner hole, and conduit outlet has the lead angle forming arc-shaped gaps with baffle.
Beneficial effect: the present invention adopts the baffle of quad cone, the depositing dust medium of jet expansion is made to form the spraying of arc fan, better can wrap up drill bit, the first-class brill of cut cuts parts, range of scatter is wide, depositing dust medium use amount can be reduced again simultaneously, the area coverage of depositing dust medium (water, the aqueous solution or foam) and the effective rate of utilization of depositing dust medium can be improved, reduce in depositing dust process with the excessive negative issue brought of water.Use with multiple arc fan nozzle combination and can form airtight annulus, parcel is comprehensively realized to cylinder or conical dirt space of producing.The fluid passage of this nozzle is smooth greatly, prevents nozzle blockage, and nozzle atomization amount is large, easy to use, safe and reliable, can be used for the dust prevention and control that down-hole and ground etc. carry out boring when cutting operation, substantially increases 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 carrying out boring when cutting operation of cut, also can be used for the occasion that other need arcuation fan nozzle.Its structure is simple, injection is even, low discharge, high impact forces, Utilizing Rate are high, has practicality widely.
