The specific embodiment
The utility model provides a kind of novel semi-circular piston to entrainment device for reducing dust, for making the purpose of this utility model, technical scheme and effect clearer, clear and definite, below the utility model is further described.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The utility model provides a kind of novel semi-circular piston to entrainment device for reducing dust, as shown in Figure 1, Figure 2 with shown in Fig. 3, it comprises dust-absorbing tube 1, dust-absorbing tube 1 is being evenly arranged a plurality of atomizing de-dusting mechanism 2 towards combining on the side of pick face, dust-absorbing tube has been evenly arranged a plurality of suction ports 3 on 1 residue side, combine pick flour dirt through a plurality of atomizing de-dusting mechanism 2 atomizing de-dustings, residue is combined pick flour dirt and is sucked in described dust-absorbing tube 1 through a plurality of suction ports 3.What it was concrete is to inhale device for reducing dust to be arranged on development machine the place ahead, the outlet of a plurality of atomizing de-dusting mechanism 2 is met head on towards work plane, heading end with development machine during use moves, make water smoke can better touch the dust that tunneling machine cutting produces, and on dust-absorbing tube 1, have a plurality of suction ports 3, in atomizing de-dusting, cause the reduction of dust-absorbing tube 1 internal pressure, thereby form strong negative pressure, suction port 3 is affected by negative pressure, can be to the dust overflowing from different perspectives, different directions is caught, realized the dust suction of dust has been purified, thereby make the dust overflowing again pass through spray field, having realized one-time dedusting combines with secondary dust suction, the dust Control that comprehensive pick operation is produced is in driver the place ahead.
In order to realize one-time dedusting, combine with secondary dust suction, dust-absorbing tube 1 can adopt different technological means from atomizing de-dusting mechanism 2, but in another preferred embodiment of the present utility model, above-mentioned dust-absorbing tube 1 is semicircle annular canister, a plurality of atomizing de-dusting mechanism 2 is evenly arranged along semicircle annular canister periphery, form atomizing de-dusting face, because dust-absorbing tube 1 is semicircle annular canister, institute is so that dust-absorbing tube 1 can better be fixed on the development machine rear of meeting head on, the atomizing de-dusting face area coverage that atomizing de-dusting mechanism 2 is formed is maximum, to combining the dust of pick operation generation, carry out maximum atomizing de-dusting.For another example atomizing de-dusting mechanism 2 is to 45 degree angles with semicircle annular canister and arranges, water smoke is sprayed from different perspectives, in driver the place ahead, form full section mist field, can effectively wrap dirt source.
Atomizing de-dusting mechanism 2 comprises nozzle 4, increaser 5 and is arranged on the induction tunnel 6 on dust-absorbing tube 1, and increaser 5 is arranged on induction tunnel 6 front ends, and induction tunnel 6 rear ends are arranged on sweep-up pipe 1, and nozzle 4 is arranged in sweep-up pipe 1, with the corresponding position of induction tunnel 6 rear ends; The nozzle 4 of each atomizing de-dusting mechanism 2 is all connected with a feed pipe 7.Feed pipe 7 supplies water to each nozzle 4, and nozzle 4 forms water smoke by water by induction tunnel 6, increaser 5 ejections, to combining pick face, carries out atomizing de-dusting.The water of nozzle 4 is simultaneously during from the interior ejection of dust-absorbing tube 1, also can take away the most of air in dust-absorbing tube 1, make the inside and outside pressure reduction that forms of sweep-up pipe 1, cause the negative pressure in dust-absorbing tube 1 to raise fast, make constantly in a plurality of suction ports 3, to enter in dust-absorbing tube 1 containing dust air, and due to each suction port towards difference, thereby can better catch the dust in development machine the place ahead, and the current that spray with nozzle 4 are in the interior mixing of induction tunnel 6, dust tends to consistent gradually with the speed between spraying jet, during by increaser 5, dust can be fully moistening by water smoke, and be discharged from sedimentation, thereby reach the object of depositing dust, improved the efficiency of dust collection of inhaling device for reducing dust.
Further, above-mentioned a plurality of suction ports 3 are evenly arranged in the top side face and trailing flank of dust-absorbing tube 1, thereby more fully catch the dust in development machine the place ahead.And the two ends of above-mentioned semicircle annular canister are separately positioned on fixed connecting plate 8, the corresponding position that fixed connecting plate 8 is met head on for being arranged on the pick face of combining or development machine, has facilitated the installation of dust-absorbing tube 1.But also semicircle annular canister can be connected with a suction fan, further having strengthened the negative pressure of dust-absorbing tube 1, feed pipe 7 is connected with a water pump by connector 9, for supplying water to a plurality of nozzles 4.
Certainly; more than explanation is only preferred embodiment of the present utility model; the utility model is not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the instruction of this manual; that makes is allly equal to alternative, obvious variant, within all dropping on the essential scope of this manual, ought to be subject to protection of the present utility model.
