Description
Technical field
The present invention relates to constructing tunnel device, specifically a kind of tunnel tunnel face dust-extraction unit.
Background technique
The dust pollution tunnel air that tunnel blasting excavation and first pneumatically placed concrete generate, seriously endangers the body of staff
Health.Traditional tunnel is dust-proof, dust removal method is mainly based on the measures such as tunnel watering, ventilation by pipes, ventilation by ducts,
Although this method structure is simple, it is easy to set up, there is also two drawbacks: first, adsorbing depositing dust using waterpower, by tunnel
Lengthwise dust self weight depositing dust is squeezed outside fume gases to hole by wind-force, and this scale removal process is easy the entire tunnel of pollution, is made
Decline at integrated air quality in tunnel, and reentrainment of dust easily occurs；Second, watering dedusting easily causes steam on a large scale
Atomization, there are electricity consumption hidden danger, and wind pipe type or ventilation by ducts are grown because draft tube liner is laid, and equipment investment is larger, dedusting time
It is long, it is ineffective.Therefore, it in order to solve the problems, such as that traditional tunnel dedusting method is ineffective, designs a kind of suitable for tunnel
Dust-extraction unit be very necessary.
Summary of the invention
The present invention is ineffective in order to solve the problems, such as traditional tunnel dedusting method, provides a kind of tunnel tunnel face and removes
Dirt device.
The present invention is achieved by the following technical scheme:
A kind of tunnel tunnel face dust-extraction unit, including the inspection of splash guard trolley, forced ventilation air hose, dust-extraction unit, dust concentration
Survey instrument and controller；
The splash guard trolley is equipped with arch door frame close to one end of face, and the arch door frame is by the main platform of splash guard trolley
It is divided into two parts up and down；The top of arch door frame is linked with screening dust cloth, stayed on screening dust cloth there are two perforation；It is described forced logical
A perforation of the wind air hose sliding on screening dust cloth；
The dust-extraction unit includes dust-break shutter door, flue dust diversion pipe, collision type inertial dust separator, sack cleaner and water in dust removal
Case；The dust-break shutter door closes the lower part of arch door frame；The flue dust diversion pipe is longitudinally disposed on main platform, and flue dust is led
Another perforation of screening dust cloth is run through in the front of flow tube, before the tubaeform nozzle of flue dust diversion pipe front end is located at splash guard trolley
It is square, jet blower is provided in tube body；The collision type inertial dust separator, sack cleaner and dust-proof water tank are all set in master
On platform, the entrance of collision type inertial dust separator is connected to the rear end of flue dust diversion pipe, the entrance of outlet and sack cleaner
Connection, the outlet of sack cleaner are connected to the entrance of dust-proof water tank, and the outlet of dust-proof water tank communicates with the outside world；
The dust concentration detector is set to the front end of flue dust diversion pipe；
The controller is set on splash guard trolley for controlling dust-extraction unit；The signal output end of dust concentration detector
It is connect with the signal input part of controller；Controller respectively with dust-break shutter door, jet blower, collision type inertial dust separator, bag
The connection of the control terminal of formula deduster and dust-proof water tank, the signal output end of controller are connect with communication equipment outside tunnel.
Working principle:
When smoke content is higher in dust concentration detector test to tunnel, starts dust-break shutter door by controller, make
The lower part of arch door frame is closed, while starting jet blower, collision type inertial dust separator, sack cleaner and dust-proof water tank
It is dusted work；Information in tunnel can be transferred to outside tunnel by controller, and staff is facilitated to understand situation in Tunnel.
It is introduced new air into tunnel from the rear end of forced ventilation air hose, the structure across screening dust cloth is reduced to waterproof
The mobile limitation of pallet vehicle, avoids that ventilation air hose is separately provided on splash guard trolley, reduces the investment of equipment.The cigarette of face
Dirt is inhaled into flue dust diversion pipe under the action of jet blower, after collision type inertial dust separator and sack cleaner, is led to
Enter in dust-proof water tank, finally clean air is released in tunnel, realizes dedusting function.
This structure combined with trolley is realized that dedusting carries out simultaneously with trolley work, is improved work efficiency.
Controller includes manual opening-closing mode and automatic open close mode.The dust concentration of setting automatic open close in controller
Threshold value, when dust concentration reaches the threshold value started automatically in tunnel, controller starts dust-extraction unit automatically, when flue dust in tunnel
When concentration reaches the threshold value being automatically closed, dust-extraction unit is automatically closed in controller；When staff can also pass through hand in tunnel
Dynamic opening and closing mode opens or closes dust-extraction unit.
The controller is PLC.
Structure of the invention design rationally, solves the problems, such as that traditional tunnel dedusting method is ineffective, is suitable for tunnel
Dedusting operation when construction.
