Description
Technical field
The rig dust arrester of the integrated control of dust when the utility model relates to a kind of bore operation belongs to the manufacturing field of dust arrester.
Background technology
The dust arrester of the control form of blowback again after present rig generally adopts high speed piston motor direct connection fan form and blowback control to adopt the rig probing to finish.The centrifugal force that the high speed piston motor drives the generation of fan high speed rotary makes air obtain kinetic energy, through spiral case and spiral case outlet diffuser part kinetic energy is converted into static pressure then.Like this, the air of blower fan outlet is exactly have a constant static-pressure distinguished and admirable, utilizes the distinguished and admirable dust that produces when collecting rig boring, after the rig probing finishes automatically to the filter core purge.But the vibration that rig when boring produces, the accumulation of dust, extraneous distinguished and admirable trend all can produce the fan under high speed rotary and have a strong impact on, and filter core can not obtain timely that purge stops up easily during bore operation.Produce shake when making the fan revolution, to the certain radial load of power transmission shaft generation of high speed piston motor, thereby cause the end bearing heating of high speed piston motor to damage, filter core breakage, dust collecting effect reduce.
Summary of the invention
Weak point in the background technology, the utility model provides the dust arrester blower fan driving control system of a kind of rig with integrated dust, make whole rig drilling efficiency significantly improve, reduced the damage to drive motor and filter core, the pollution of environment, the consumption of the energy greatly.
To achieve these goals, the utility model adopts following technical scheme: the rig dust arrester, comprise the filter core group, casing, the filter core group is rearranged by a plurality of filter cores and the filter core group is positioned at casing, the blower fan transmission mechanism is positioned at the casing top, the blower fan transmission mechanism comprises drive motor, gear-box, air box, be provided with driving gear in the gear-box, driven gear, blade shaft, be provided with fan in the air box, drive motor is positioned at the gear-box top, its clutch end is connected with the gear-box inner pinion gear, driven gear engagement in driving gear and the gear-box, drive the driven gear action by driving driving gear, driven gear is connected with blade shaft, and blade shaft stretches out gear-box one end and is connected with the air box internal fan.
As to of the present utility model a kind of preferred, casing inner filter core group top is provided with filter core purge control system, described filter core purge and wash system comprises PLC controller, impulse electromagnetic valve, screw-rod air compressor, blowing mouth, the PLC controller regularly sends pulse signal control impuls electromagnetic valve switch, impulse electromagnetic valve opens then that Compressed Gas enters blowing mouth in the screw-rod air compressor, closes then to stop Compressed Gas and enter blowing mouth.
As to of the present utility model a kind of preferred, blowing mouth is above gap between filter core and the filter core.
Rig adopts the blower fan transmission mechanism with dust arrester, the purpose of doing like this is: the fan high speed rotary is to pass to fan again after driving one group of efficient gear up by drive motor, the shake radial load that fan produced is like this born by blade shaft, reduced damage greatly, improved service life motor.Rig adopts the filter core purge and wash system with dust arrester, the purpose of doing like this is that the PLC controller regularly sends pulse signal control impuls electromagnetic valve switch, impulse electromagnetic valve is opened then in the screw-rod air compressor Compressed Gas and is entered blowing mouth filter core is carried out purge one time, closes the purge that then stops filter core.By set the PLC controller send time pulse signal realize the work of boring on one side on one side to filter core circulation carry out purge, the effective like this filter core blocking problem of avoiding improves dust catching efficiency and becomes porosity.
The utility model is compared with background technology, has stable drive, has reduced the damage to drive motor and filter core, and dust collecting effect is good, has obvious improvement compared with the prior art.
