The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
The dust pelletizing system that a kind of pneumatic dry type is as shown in Figure 1 drilled, comprise hole sealing tube 10, hole sealing tube 10 is fixed on to be treated on the boring the ground wall, be provided with port seal 20, cyclone dust collector 30 and spray dust remover 40 behind the hole sealing tube 10 successively, be linked to be a confined space with rubber hose 50 between port seal 20, cyclone dust collector 30 and the spray dust remover 40.
As Fig. 2, shown in Figure 3, port seal 20 comprises tubular body 21, the inside of tubular body 21 is provided with drilling rod 25, the shaft of drilling rod 25 is connected with air line, the axis of drilling rod 25 is concentric with the axis of tubular body 21, one end of tubular body 21 is provided with flange 22, flange 22 links to each other with the flange of hole sealing tube 10, the other end of tubular body 21 is connected with the drilling rod big envelope 23 that passes through for drilling rod 25, the barrel of tubular body 21 is provided with ash hole 24, and ash hole 24 links to each other with the import of cyclone dust collector 30 by rubber hose 50.
As preferred version of the present utility model, drilling rod big envelope 23 adopts the annulus of rubber material, the endoporus of annulus matches with drilling rod, adopt the rubber material can avoid in the drilling rod running because of rocking the breach that causes, the dust sealing that thoroughly will hole and discharge, avoided drilling rod to rock the spark that produces in the process simultaneously, as preferred scheme, the annulus of rubber material is designed to split with tubular body 21, like this can be according to the difference of drilling rod model, be equipped with the drilling rod big envelope of various different sizes, be convenient to the replacing of drill bit.
As shown in Figure 4, cyclone dust collector 30 comprises urceolus 31, vertically be provided with import 32 on the upper end barrel of urceolus 31, the lower end of urceolus 31 is connected with back taper ash releasing tube 33, the bottom of ash releasing tube 33 is provided with ash-valve 34, is provided with inner core 35 in the urceolus 31, and the axis of the axis of inner core 35, urceolus 31 and the axis of ash releasing tube 33 are concentric, the outlet 36 of inner core extends urceolus 31 outsides, and the outlet 36 of inner core links to each other with the import of spray dust remover 40 by rubber hose 50.
As first order dust arrester, cyclone dust collector 30 is that the solid particle of the dust that produces when utilizing centrifugal force that swirling eddy produces with boring is separated from air-flow, because import 32 is perpendicular to the barrel setting, so the pressure wind in the air line equals to enter the urceolus from the side of urceolus 31, promptly press wind tangentially to enter urceolus through import, because dust-contained airflow enters urceolus with higher speed, to become circumference by rectilinear motion moving moving for air-flow like this, swirling eddy is downward in the shape of a spiral along the inwall of urceolus, form outer rotational gas flow, dust-contained airflow produces centrifugal force in rotary course, grit is got rid of to outer tube inner wall, grit loses inertia force and falls along outer tube inner wall, enter ash releasing tube 33, the dust of precipitation is discharged by the ash-valve 36 that ash releasing tube 33 bottoms are provided with, because ash releasing tube 33 is inverted cone shape setting, so the outer rotational gas flow that rotation descends is when arriving cone, because of conical contraction is drawn close to the center of cyclone dust collector, when air-flow arrives a certain position, cone lower end, promptly can flow with the same direction of rotation shape of from bottom to top continuing to spin, rotational gas flow drives grit and runs to spray dust remover 40 by inner core 35 through inner core outlet 36 in promptly forming.
As shown in Figure 5, spray dust remover 40 comprises spray chamber 41, the import of spray chamber 41 is provided with suction pipe 42, suction pipe 42 links to each other with the inner core outlet 36 of cyclone dust collector 30, the outlet of spray chamber 41 is provided with filter screen dehydrator 43, and spray chamber 41 is provided with water inlet pipe 44, and an end of water inlet pipe 44 links to each other with external high pressure water route, the other end of water inlet pipe 44 is connected with nozzle 45, and the injection direction of nozzle 45 points to the outlet of spray chamber 41.
As preferred version of the present utility model, nozzle is positioned on the central axis of spray chamber's horizontal direction, like this during inject high pressure water and the collision area of grit wider.
As second level dust arrester, when grit is run to spray dust remover from inner core outlet 36, water under high pressure and gas molecule that nozzle ejection is come out bump, make water droplet further be broken into the more droplet of small particle diameter, these droplets that carry dust can cohesion become mud after by filter screen dehydrator 43 discharges, and prevents secondary pollution.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
