Specific embodiment
As in Fig. 1～2, a kind of to tunnel mobile type dust collector, including ventilation duct 2, ventilation duct 2 is provided with air exhauster 3, excellent
Choosing, adopt centrifugal exhauster in this example, the air inlet 1 of ventilation duct 2 is located near the position of face, ventilation duct 2 with remove
29 connection between dirt, the dust mouth 5 of ventilation duct 2 are located in 29 between dedusting, opening down.Vent hose is additionally provided with ventilation duct 2
4, allow ventilation duct to stretch to a certain extent.
Between dedusting, 29 both sides are provided with running gear, and in preferred scheme, described running gear is walking supporting rail 26,
In order to adjust orientation.Between dedusting, 29 can also adopt other running gears, such as running gear system.
Spray equipment is provided with 29 between dedusting, in preferred scheme, described spray equipment is multiple shower nozzles 8.In this example
It is using four rotary nozzles, rectangular to be arranged in 29 between dedusting.To guarantee to cover between whole dedusting 29 horizontal cross-section.
Header tank 28 is provided with below 29 between dedusting, 29 are provided with gas discharge outlet 6 between dedusting, in this example, gas are discharged
Mouth 6 is arranged on top.In preferred scheme, gas water separating filter device 7 is additionally provided with gas discharge outlet 6.For reducing discharging
The humidity of gas, usual gas water separating filter device 7 is by the way of condensation separation.
The import of suction pump 22 is connected with header tank 28, is provided with water pumping valve 23 in the import of suction pump 22, suction pump 22
Outlet is connected with spray equipment.Thus structure, can recycle shower water carries out dedusting, reduces the consumption of water.
As in Fig. 1, the dust mouth 5 of ventilation duct 2 is located at the lower section of spray equipment, spray equipment and dust mouth to preferred scheme
Grid 11 is provided between 5.Arrange grid 11 effect be：In the presence of 4 rotary nozzles, water smoke convolution has been flown away downwards
To pressing dirt, dust-laying effect, part water smoke directly to impinge upon on the grid grid of steel alloy bar formation, large water droplet is gathered into by one
Adsorbing powder dust a bit by larger uplift pressure floating, pressure.
In preferred scheme, the drainage basket strainer 15 being in tilted layout is provided with below the dust mouth 5 of ventilation duct 2, drainage is removed
The inclination angle of dirt net 15 at 3-8 °, preferably 5 °.
The relatively low one end of drainage basket strainer 15 is provided with silt groove outlet 20, and silt groove outlet 20 is provided with silt outlet lock
16.Thus structure, can make silt during gliding along drainage basket strainer 15, silt is separated with water, and silt is from mud
Husky groove outlet 20 is discharged, and water is then entered into and is circulated in header tank 28.
In preferred scheme, filter screen silt cleaner 14 is provided with drainage basket strainer 15.Thus structure, it is to avoid drainage is removed
Dirt net 15 is blocked.Filter screen silt cleaner 14 in this example adopts vibrating device.
Flow deflector 12 is additionally provided with the both sides of drainage basket strainer 15, in order to the discharge of silt.
In preferred scheme, riffler 30 is provided with the lower section of drainage basket strainer 15, is provided with lattice in one end of riffler 30
Grid outlet 25, grid outlet 25 are nearby provided with desilting downflow weir 19, and desilting downflow weir 19 is nearby provided with sand surfing and opens and closes road 18.
Thus structure, makes the water after filtration the step of precipitating for one, further reduces the silt content in water, reduce to suction pump 22
Abrasion.Preferably, riffler 30 is in tilted layout, and inclination angle is 1 °, thus structure, make silt be all deposited on desilting downflow weir 19 it
Afterwards, it is easy to from sand surfing keying road 18 be rinsed.
In preferred scheme, described 28 top of header tank is provided with water intaking valve 21, and bottom is provided with blowoff valve 24, header tank 28
Level sensor 17 is additionally provided with inside.Thus structure, is easy to keep the water level of header tank 28, the blowoff valve 24 of setting, for clearing up
Silt in header tank 28.Described level sensor 17 should arrange two monitor values, be peak level and lowest water level respectively,
When lowest water level is reached, water intaking valve 21 is opened to moisturizing in header tank 28, when peak level is reached, and water intaking valve 21 is closed and stopped
Only moisturizing.
In preferred scheme, between described dedusting, 29 is sandwich, and the bottom of interlayer is provided with the side channel 27 that catchments, side of catchmenting
Barometric pipe 13 is provided with groove 27,29 outer wall is provided with blow vent 10 between dedusting, and blow vent 10 is connected with interlayer.In dedusting
Cheng Zhong, it is understood that there may be the not smooth problem of 6 aerofluxuss of gas discharge outlet, so as to cause windage too high, has influence on whole dust arrester
Dust removing effects, the barometric pipe 13 of setting can 29 between dedusting in air pressure it is higher when, discharge pressure, and gas have passed through collection
Water side channel 27 is washed, it is to avoid dust is overflowed from blow vent 10.
The present invention device job step be：First before development machine digging excavation, water intaking valve 21 is opened, by pick
The feed pipe for entering machine stores the water of demarcation in header tank 28, when development machine starts shooting cut, whole dust arrester is synchronously opened
Start shipment row.Under the driving of air exhauster 3, dust air stream is entered in 29 between relatively closed dedusting through ventilation duct 2.Water smoke
Spray from shower nozzle 8, by the dust adsorption in dust air stream, and run downwards.Part water smoke is directly impinged upon on grid 11, is gathered
Some are received integrated large water droplet the adsorbing powder dust of larger uplift pressure floating, pressure.Clean malaria is through gas-water separation
Filter 7 is discharged from the gas discharge outlet 6 that gradual change is spread,
Dust is mixed in water smoke water droplet, drops into drainage basket strainer 15 under gravity, what silt water was constantly assembled
Meanwhile, under oblique prone downslide force action so that silt sewage is arranged to silt groove outlet 20.
Silt sewage take advantage of a situation flowing when, by the filter layer in drainage basket strainer 15 will more clean water stream infiltration under
Come, the riffler 30 entered into above header tank.When current pass through desilting downflow weir 19, the fine silt for containing is blocked in
Before desilting downflow weir 19, clean water stream enters into header tank through grid outlet 25, supplies water by suction pump 22
Feed pipe 9.
Need to demarcate two characteristic level of water, preferred placement level sensor 17, when water level is less than minimum at header tank
During waterline, supply water from trend header tank, stop supplying water when water level reaches highest characteristic level of water, to realize being automatically replenished water
Requirement.
Although part silt sewage is through primary 15 permeation filtration of drainage basket strainer, through second desilting downflow weir
19 barrier depositions, but still have silt to be mixed into bottom header tank unavoidably, it is therefore necessary to periodically removing silt sediment.Cleaning silt
Step is to first turn on sand surfing to open and close road 18 and blowoff valve 24, opens suction pump 22, closes water pumping valve 23, open into wetting system simultaneously
Appropriate big flow is adjusted, is flowed out along drainage basket strainer 15 in the gravity flow effect next part water of water, while coordinating filter screen mud
The silt on upper strata is cleared up away by the vibration of husky cleaner 14.Another part current reach riffler through drainage dedusting stratum reticulare 15
And header tank, unnecessary silt sewage is opened and closed into road 18 by sand surfing and blowoff valve 24 is rinsed out.
The above embodiments are only the preferred technical solution of the present invention, and are not construed as the restriction of the present invention, this
Technical characteristic in the technical scheme that bright protection domain should be recorded with claim, including the technical scheme of claim record
Equivalents are protection domain.Equivalent i.e. within this range is improved, also within protection scope of the present invention.
