Abstract
The utility model discloses a kind of tunnel veil dust-extraction unit, and including the spray tube being set in tunnel vertically, spray tube semicircular in shape, closed at one end, the other end of spray tube are connected with water inlet pipe, and reinforcing rib is equipped between water inlet pipe and spray tube；More than two nozzle components are equipped with along the pipeline uniform intervals of spray tube, each nozzle component includes two spray heads, and two spray heads are respectively facing the setting of tunnel front and rear direction；Spray tube is fixed in tunnel, and the water flowing into spray tube by water inlet pipe is then sprayed water by nozzle component, is settled in time when can generate dust after tunnel blasting, easy to use, good dedusting effect；Reinforcing rib can prevent the junction between spray tube and water inlet pipe to be broken, and extend the service life of equipment.
Description
Technical field
The utility model relates to roadway opening operating equipment technical field, specifically a kind of tunnel veil dust-extraction unit.
Background technique
During Mine Tunnel Construction, after face blast, a large amount of dust and toxic and harmful gas can be generated, in order to guarantee to pacify
Entirely, watering method and wind generally arrange method at present.Traditional meets head on to sprinkle water, due to being limited by equipment and time, dust-laying effect
Bad, when adding tunnelling operation, space is small, and equipment is more, and large-scale dust removal installation is installed in inconvenience.It is to pass through ground that wind, which arranges method,
Relay portable blower in colloid air duct, tunnel and colloid air duct in portable blower and pit shaft supply sufficient air quantity to working face, are made for
Industry personnel breathing, and dust is discharged, this method dust discharge time is longer, and when air quantity of meeting head on is larger, rock dirt flies upward influence
The sight of operating personnel is unfavorable for improving production efficiency, and the waste air of discharge will pollute ambient air quality.
Utility model content
The purpose of this utility model is to provide a kind of tunnel veil dust-extraction unit, which can effectively remove tunnel and open
The dust that construction generates is opened up, good dedusting effect guarantees the safety of construction.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of tunnel veil dust-extraction unit, including the spray tube being set in tunnel vertically, spray tube semicircular in shape, spray tube
Closed at one end, the other end be connected with water inlet pipe, between water inlet pipe and spray tube be equipped with reinforcing rib；Pipeline along spray tube is uniform
More than two nozzle components are equipped at intervals with, each nozzle component includes two spray heads, and it is forward and backward that two spray heads are respectively facing tunnel
Direction setting.
The utility model has the beneficial effects that spray tube is fixed in tunnel, the water flowing into spray tube by water inlet pipe, after
And sprayed water by nozzle component, it is settled in time when can generate dust after tunnel blasting, easy to use, good dedusting effect；Add
Strengthening tendons can prevent the junction between spray tube and water inlet pipe to be broken, and extend the service life of equipment.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Specific embodiment
In conjunction with shown in Fig. 1 and Fig. 2, the utility model provides a kind of tunnel veil dust-extraction unit, including is set to tunnel vertically
Interior spray tube 1,1 semicircular in shape of spray tube, closed at one end, the other end of spray tube 1 are connected with water inlet pipe 2, water inlet pipe 2 and spray
Reinforcing rib 3 is equipped between shower pipe 1；Pipeline uniform intervals along spray tube 1 are equipped with more than two nozzle components 4, each spray head
Component 4 includes two spray heads, i.e. first spray head 4a and second spray head 4b, and two spray heads are respectively facing the setting of tunnel front and rear direction；
Preferably, the angle between two spray heads of each nozzle component is 60o.
Spray tube 1 is fixed in tunnel, and the water flowing into spray tube by water inlet pipe 2 is then sprayed water by nozzle component 4
Out, it is settled in time when can generate dust after tunnel blasting, dust removing effects are optimal when the angle between two spray heads is 60o.This
Utility model is easy to use, good dedusting effect；Reinforcing rib can prevent the junction between spray tube and water inlet pipe to be broken, and prolong
The service life of long equipment.
The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model
Limitation；Anyone skilled in the art, it is all available in the case where not departing from technical solutions of the utility model ambit
The methods and technical content of the disclosure above makes many possible changes and modifications to technical solutions of the utility model, or is revised as
The equivalent embodiment of equivalent variations.Therefore, all contents without departing from technical solutions of the utility model, according to the utility model
Technical spirit any simple modification, equivalent replacement, equivalence changes and modification made to the above embodiment are still fallen within practical
In the range of the protection of new technique scheme.
