Detailed description of the invention
By reference to the accompanying drawings, detailed description of the invention of the present utility model is described further:
Railway bed is as shown in Figure 1 trickled down coal dust and is removed special separator, comprise the two-stage separator connected by curvature pipe 5, primary separator is cyclone separator 3, second-stage separator is Bag filter separator 6, cyclone separator 3 is supported by support 2, the bottom of cyclone separator 3 is connected with vane type discharger 1, and the top of described curvature pipe 5 is provided with explosion proof door 4.Wherein, the diameter of curvature pipe 5 selects according to conveying capacity.
As shown in Figure 2,3, described cyclone separator 3 comprises cylindrical drum, cone cylinder 34 and the blanking dsah-pot 35 that transition from top to bottom connects, the bigger diameter end of described cone cylinder 34 upper, miner diameter end under, described cylindrical drum comprises cylindrical column casing 32 and inner cylindrical tube 33, the epimere side of cylindrical column casing 32 is provided with the spiral case rectangle air inlet 36 through with cylindrical column casing 32, the top of inner cylindrical tube 33 is connected with curvature pipe 5 is through, is provided with the spiral plate 31 of 180o between cylindrical column casing 32 and inner cylindrical tube 33.Because of coal particle size that railway bed is unrestrained uneven with, wherein may be large to comprising the coal grain of about 10mm and the little dust to below 0.005mm, when coal dust enters (region between cylindrical column casing and inner cylindrical tube) in the cylinder of primary separator through spiral case rectangle air inlet 36, coal dust is under the effect of spiral plate 31, paste cylindrical column casing 32 inwall with air-flow to operate after a few at centrifugal force, inertia force is separated with under Action of Gravity Field, the coal grain being greater than 0.005mm falls through blanking dsah-pot 35 finally by vane type discharger 1 discharge recovery, be less than the dust air current flow of 0.005mm to boring after bottom cylinder 34, turn back and upwards enter inner cylindrical tube 33 and enter second-stage separator through deep camber pipe 5 again.
The Large stone coal grain (being greater than 0.005mm) of 98% can be separated by one-level separation process, and the coal grain after separation flows out downwards, and dust air-flow upwards enters second-stage separator, and path is each other noiseless, and there will not be back mixing to wait to expect phenomenon, discharging is smooth and easy; When containing the mixed flow of coal dust in the cylinder of cyclone separator during rotational flow, high concentration pellet contacts with the barrel of cylindrical column casing 32, decrease the friction of air and cylindrical column casing barrel, thus flow differential pressure is decreased, as when the air-flow at air inlet 36 place is 20m/s, blanking per hour 17 tons, the windage that this air velocity produces is less, therefore the stream pressure at air inlet 36 place and the differing pressure of dust air-flow in the exit of inner cylindrical tube 33 little, be only tens millimeters of water.
As shown in Figure 4,5, 6, described Bag filter separator 6 comprises the outer cylindrical shell being arranged with reinforcement 63 and the disposal box 64 be connected to below cylindrical shell, the bottom sides of disposal box 64 is provided with residue-removing door 65, the epimere of cylindrical shell is connected with the clear bag 61 of some pulses, the middle part of cylindrical shell is provided with the horizontal Dou 62 be connected with curvature pipe 5, be provided with cross passage 67 in the middle of inner barrel, the space mounting that cross passage 67 and cylindrical shell are formed has some skeleton supports 66 vertically.Described Bag filter separator 6 is high vacuum separator, its pressure is high, and dust-laden is high, and the structural strength of its cylindrical shell must meet under vacuum pressure-370mmHg indeformable, therefore the inner barrel of this separator adopts skeleton supported design, and the peripheral fence type muscle that adopts is strengthened.
After entering second-stage separator containing the air-flow of dust, with cross passage 67 rapid diffusion in the middle of inner barrel, thus be conducive to the filtration of the clear bag of pulse 61 pairs of dust, and cross passage 67 can with skeleton support 66 organic structure, more compact structure, effectively prevent conflicting and the secondary fly-up of bottom disposal box of dust incoming flow and air pulse, make dust fall steadily effective, dust all effectively can be collected, discharge clean air, pollution-free, the windage of this process is 150mmH
2o.
In order to avoid the impact that the clear bag of pulse fluctuates on system airflow, have employed the way reducing pulse clear bag quantity, accelerate clear bag speed, 64 clear bags of pulse (i.e. a small amount of separation method repeatedly) are set altogether.Explosion proof door 4 is mainly used in release, ensures the safety in operation process.Because of the clear bag of pulse be utilize terylene needled felt to filter, clear bag is effective, and this separator before filter with filter after two shape chambeies isolate tightly, nothing is leaked out, and effectively can ensure that dust can not enter the vavuum pump be connected with separator, extends the service life of vavuum pump.
Disposal box 64 is fixing seal formula, ensure the internal pressure stabilises of separator, the residue-removing door 65 be installed on bottom disposal box 64 comprises cover plate 70 and is installed on two groups of eccentric Quick compressing mechanisms on cover plate 70, two groups of eccentric Quick compressing mechanisms are equidistantly installed up and down along cover plate 70 center line, as shown in Figure 7,8.Often organize eccentric Quick compressing mechanism and comprise two pieces of horizontal holders, 68, eccentric rod group 69 and two buckles 72, horizontal holder 68 is arranged at cover plate 70 both sides and hinged for bracket eccentric rod group 69 with disposal box 64, two buckles 72 are symmetrical to be installed on cover plate 70, for the eccentric rod group 69 that is locked.Described eccentric rod group 69 comprises reducing bar 69a, handle 69b and eccentric wheel 69c, two eccentric wheel 69c are installed in the large footpath section in the middle part of reducing bar 69a by its eccentric orfice, handle 69b bias is connected to the centre of reducing bar 69a, the axis of handle 69b and the axis of eccentric wheel 69c are positioned at same plane, the two ends of reducing bar 69a to be installed on respectively in groove that horizontal holder 68 hangs the section of going out and to be fixed, as shown in Fig. 9,10 by buckle 72.This residue-removing door is in stable condition when closing, and has auto-lock function, when needs are expected clearly, rotates two pieces of horizontal holders 68 and make it transfer, and cover plate 70 can be flipped open discharging by the upper and lower handle 69b of operative, and thus this residue-removing door is opened and facilitated, and is beneficial to execute-in-place.
Wherein, zero component not making specified otherwise in the utility model is existing known technology.
