Description
Technical field
The utility model relates to down-the-hole drill admission gear device, is specifically related to a kind of down-the-hole drill bilateral air agreement road.
Background technique
Down-the-hole drill can produce a large amount of dust when boring work, and motor in down-the-hole drill admission gear is wanted a large amount of air of inspiration in the course of the work, if do not have the direct launched machine suction of filtration of air-strainer can cause engine scuffing serious with the air of a large amount of dust.Like this, the filter core of air-strainer will stick airborne dust, not only makes filter capacity decline, but also can hinder the circulation of air, causes mixed gas overrich and makes engine operation undesired, affects working efficiency.Therefore, the filter core of air-strainer is cleaning often, and cleaning several times will be changed later, has so both increased the workload of filter core cleaning, has increased again the maintenance cost of filter core.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of down-the-hole drill bilateral air agreement road, can reduce the workload of air cleaner cartridge cleaning, extends the replacing time of air cleaner cartridge, reduces maintenance cost.
In order to address the above problem, down-the-hole drill bilateral air agreement of the present utility model road, comprises motor, also comprises interior suction tude, external admission pipe; The suction port of described motor is communicated with interior suction tude; One end of described interior suction tude is communicated with one end of external admission pipe by two stage filter, and the other end is connected with air compressor; The other end of described external admission pipe is connected with main air filter cleaner, and the middle part of external admission pipe is also provided with spherical valve; Described main air filter cleaner is provided with outer air entrance; The joint of described air compressor and interior suction tude is provided with pressure regulator valve; The front end of described pressure regulator valve is provided with pressure switch; The front end of described pressure switch is provided with steam-water separator.
As preferably, the below of described spherical valve is parallel with one-way valve, and one-way valve plays scavenging action.
As preferably, described motor is 2 Cylinder engines.
The utility model advantage: the one, the cleaning work amount of minimizing air cleaner cartridge, extends air cleaner cartridge and changes the time, reduces the maintenance cost of filter core.Owing to having added spherical valve on the external admission pipe at motor, when down-the-hole drill boring work, the air compressor work being connected with interior suction tude, closes external admission pipe, air inlet work in utilizing completely.When down-the-hole drill startup and standby, air compressor is not worked, and opens spherical valve, utilizes external admission work.Like this, reduced the operating time of air-strainer, the cleaning work amount of air filtering core device filter core and the also corresponding minimizing of replacing number of times, reduced maintenance cost.The 2nd, can extend working life of motor.Although it is clean that outer air, through the filtration of air-strainer, can not be filtered completely, also can enter motor with a small amount of fine solid particle, cause the wearing and tearing of motor.When down-the-hole drill is when holing, air work in main utilization, because interior air ratio is cleaner, can increasing service life of engine.
Accompanying drawing explanation
Fig. 1 is down-the-hole drill bilateral air agreement of the present utility model road structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model down-the-hole drill bilateral air agreement road is described further:
As seen from Figure 1, down-the-hole drill bilateral air agreement of the present utility model road, comprises motor 1, also comprises interior suction tude 2, external admission pipe 21; The suction port of described motor 1 is communicated with interior suction tude 2; One end of described interior suction tude 2 is communicated with one end of external admission pipe 21 by two stage filter 3, and the other end is connected with air compressor 8; The other end of described external admission pipe 21 is connected with main air filter cleaner 6, and the middle part of external admission pipe 21 is also provided with spherical valve 5; Described main air filter cleaner 6 is provided with outer air entrance 7; Described air compressor 8 is provided with pressure regulator valve 9 with the joint of interior suction tude 2; The front end of described pressure regulator valve 9 is provided with pressure switch 10; The front end of described pressure switch 10 is provided with steam-water separator 11.
As preferably, the below of described spherical valve 5 is parallel with one-way valve 4,4 scavenging actions of one-way valve.
As preferably, described motor 1 is 2 Cylinder engines.
Between main air filter cleaner 6 and motor 1, add spherical valve 5 and one-way valve 4, when interior suction pressure is large, can regulate pressure by one-way valve 4 exhausts, make air inflow guaranteed.When air compressor is not worked, the normal work when opening spherical valve 5 and allowing outer air pass through air-strainer 6 natural aspirations not hole to guarantee rig.
When down-the-hole drill boring work, close the spherical valve 5 that is located at external admission pipe 21 middle parts, air compressor 8 work, is delivered to motor 1 by source of the gas by interior suction tude 2, and motor 1 provides power for drill hole of drilling machine work.When interior suction pressure is excessive, can discharge by the one-way valve 4 being located on external admission pipe 21.When down-the-hole drill startup and standby, air compressor 8 quits work, open the spherical valve 5 that is located at external admission pipe 21 middle parts, outer air is entered in main air filter cleaner 6 by outer air entrance 7, through single filter, by external admission pipe 21, be delivered to two stage filter 3, after again filtering, be delivered to motor 1, motor 1 provides power while starting with standby for down-the-hole drill.
External pressure regulator valve 9 between the outlet of air compressor 8 and the entrance of interior suction tude 2, pressure regulator valve 9 capable of regulating pressure, make pressure steady, can not cause air compressor to start frequent, play the effect in 8 working lifes of protection air compressor.
Pressure switch 10 is mainly used to regulate the start-stop state of air compressor 8, by regulating the pressure in gas holder to allow air compressor 8 shut down rest, has maintenance effect.
Source of the gas enters after steam-water separator 11, by the variation of gas flow and speed, the water decomposition of gas the inside is separated out and can save source of the gas, increases work efficiency, and reduces the corrosion of moisture to gas utilization unit, extension device working life.
Because rig working efficiency and energy consumption are one of key links affecting blasting work, for the deficiencies in the prior art, we transform down-the-hole drill intake duct, reached before air compressor does not start, rig utilizes outer air while starting with stand-by operation, and rig when work utilize in the good result of air, not only guaranteed air inlet quality, and be conducive to protect motor, extended service life of aeroengine, reduced the workload of air cleaner cartridge cleaning simultaneously, reduce the replacing number of times of filter core, reduced the maintenance cost of filter core, extended service life of aeroengine.
