Abstract
the utility model provides a negative-pressure atomization dust catcher at a support coal port is provided with a substrate steel pipe, one end of the substrate steel pipe is provided a funnel-shaped inlet scoop communicated with the dust catcher, the other end is provided with a spraying draught pipe with a nozzle inside through Cahlan connection and a water inlet leading in high pressure water flow is arranged on the spraying draught pipe. The arrangement of the draught pipe is adopted on the utility model, the draught pipe is arranged below four-linkage at the rear of a hydraulic support and right facing the coal port so as to generate a high speed water fog vortex field at the coal port; the bug dust is absorbed and removed in the vortex field, which avoids the water fog from blocking the view line of the operators, decreases the harm to the physical health of the worker and the safety working environment and purifies the bug dust generated at the rear of a comprehensive mechanized workface, and thus the dust catcher has good condensation rate, high efficiency of dust collection, can cover and block the drifting path of bug dust effectively and has the advantages of the reasonable structure, light weight and convenient installation and utilization.
Description
Technical field
The utility model relates to support coal discharge outlet negative pressure nebulization dust device, is particularly useful for the dedusting of down-hole, mine top-coal caving face, also is applicable to the occasion that other needs dedusting.
Background technology
Putting a large amount of dust of generation in the coal process, is one of main dust source that constitutes top-coal caving face.Existing top-coal caving face is put the Dust Control Technology in the coal process, mainly be adopt hydraulic support not tail boom mode that nozzle is installed carry out atomizing de-dusting.Because the water source one that adopts of this mode is a low pressure nature water, atomizing effect is poor, and water smoke can not be effectively and the dust landing of condensing after affine; The 2nd, the installation site is unreasonable can not effectively to cover the product dirt pits, water smoke can not effectively be blocked flowing of dust and escape, the 3rd, the shortcoming of low-pressure nozzle self, easily the obstruction life-span is low, therefore put between the frame of dust that produces in the coal process and scurry frame forefathers row space by support, concentration is far longer than national standard, workman's healthy and safe working environment is caused have a strong impact on.
The utility model content
The purpose of this utility model is according to deficiency of the prior art, and support coal discharge outlet negative pressure nebulization dust device a kind of simple in structure, effective is provided.
For achieving the above object, support coal discharge outlet negative pressure nebulization dust device of the present utility model, one matrix steel tube is set, matrix steel tube one end is provided with the funnel-form inlet scoop that communicates with it, the other end is provided with the injection induced duct of establishing nozzle in blue being connected with by blocking, sprays induced duct and is provided with the water inlet of introducing High-Pressure Water.
Described funnelform inlet scoop forms with four trapezoidal steel plate welding productions; The described injection induced duct that links to each other with matrix steel tube is staggered, and is at least 2.
Negative pressure nebulization dust device of the present utility model, but the structure of usefulness L type turn, pipe interface adopts snap joint, compact overall structure, appearance and size optimization.Adopt the arrangement of induced duct, be installed in support afterbody four connecting rods below, over against coal discharge outlet, make coal discharge outlet produce a high speed water mist rotational field, dust is absorbed to fall in rotational field and removes.Atomizing is covering of the fan covering support one rear flank portion transporter road and puts the coal space, and the inlet scoop is in support, and another is sidelong the coal scope.Cover to produce dirt pits blocking-up dust and escape, fall to remove and put the dust that produces in the coal process, particularly respirable dust, avoid water smoke to block operative employee's sight line, reduce the harm of dust and safe working environment healthy the workman.Can purify the dust that machine road, fully mechanized coal face rear portion produces, nebulization efficiency is good, and the efficiency of dust collection height can effectively cover and block the dust drift path, and is rational in infrastructure, in light weight, and advantage is installed, easy to use etc.
Description of drawings
Accompanying drawing is the utility model structural representation.
Among the figure: inlet scoop-1, matrix steel tube-2, flange-3, induced duct-4, water inlet 5.
The specific embodiment
The utility model will be further described below in conjunction with the embodiment in the accompanying drawing:
Shown in the accompanying drawing, negative pressure nebulization dust device of the present utility model, be located at the hydraulic support coal discharge outlet, mainly constitute by a matrix steel tube 2, matrix steel tube 2 one ends are provided with the funnel-form inlet scoop 1 that communicates with it, and funnelform inlet scoop four trapezoidal steel plate welding productions of 1 usefulness form, and the other end is established nozzle ejection induced duct 4 in being provided with and being connected with by flange 3, spray induced duct 4 and be provided with the water inlet 5 of introducing High-Pressure Water, matrix steel tube 2 tops are provided with fixedly otic placode.
Operating principle: the pumping plant by the tunnel provides water under high pressure to be transported between the work plane frame through pressure duct, be connected to through control valve on the water inlet 5 of High-Pressure Water, water under high pressure is assigned on the nozzle of two injection induced ducts 4, nozzle produces high speed water mist and produce the water smoke piston action in steel pipe, so the water smoke covering of the fan of high velocity jet occurs in induced duct 4 the place aheads, rear at induced duct 4 produces certain negative pressure, be delivered to inlet scoop 1 through matrix steel tube 2 after the negative pressure stack that induced duct 4 produces, staggered injection induced duct 4 ejections are covering of the fan water smoke, it is distinguished and admirable to cover machine road, rear portion, water smoke entrainment with shielding action under, put that most of dust is eliminated in the coal process.Be positioned between frame another inlet scoop of being sidelong the coal scope and catch the dust of this side with bigger negative pressure, this part absorbed dust becomes black water and sprays with water smoke along matrix steel tube 2 to induced duct 4 under the effect of water smoke piston.Along with the operation of putting the coal worker, the deduster that is fixed on the tail boom connecting rod is movable with tail boom, deduster always works in the optimum position except that dirt pits like this, the induced duct that is positioned at support one side sprays high speed water mist, be positioned at the inlet scoop of support opposite side then strong absorbing this side dust, form the water smoke rotational field of a high speed in the support rear space, dust in is along with spray at a high speed, suction rotation are removed by forced landing, near dust is fallen by part absorption and removes outside the venue, reaches efficient comprehensive purifying and puts the dust that produces in the coal operation.
