Fig. 2 is the structural representation of the present invention.
Detailed description of the invention
The invention provides a kind of portable high negative pressure weldering fume purifier, volume is little, the high movement of automaticity is flexible, detachable maintaining convenient.Below in conjunction with specific embodiment and Figure of description, the present invention is described in detail.
As depicted in figs. 1 and 2, portable high negative pressure provided by the invention weldering fume purifier includes housing, and housing is made up of protecgulum 10, bonnet 20, upper cover 30 and base plate 60.Protecgulum 10 is provided with air inlet 11, and bonnet 20 is provided with gas outlet, and enclosure interior is sequentially provided with effective filter 70 and high negative pressure blower fan 80 from front to back, and effective filter 70 is relative with air inlet 11, and the exhaust end of high negative pressure blower fan 80 is relative with gas outlet.Under operation, high negative pressure blower fan 80 produces negative pressure, makes the flue dust produced in welding, cutting and the polishing course of processing enter effective filter 70 from air inlet 11, after effective filter 70 filters, discharges from gas outlet.
The rear of air inlet 11 is provided with deflector 16, and multiple filter cylinders that the flue dust entered from air inlet 11 is equally distributed in effective filter 70 by deflector 16 are filtered.
Protecgulum 10 is additionally provided with pressure-sensitive switch 12, electric current inductive switch 13 and for adjusting the speed governing knob 14 of the rotating speed of high negative pressure blower fan 80, pressure-sensitive switch 12 is for detecting the internal pressure of effective filter 70, when effective filter 70 accumulates too much flue dust, when the force value that pressure-sensitive switch 12 detects exceedes preset value, portable high negative pressure weldering fume purifier can quit work in power-off, to prevent from being made high negative pressure blower fan 80 damage by flue dust blocking highly effective defecator 70.Whether electric current inductive switch 13, for detecting the operating current of welding machine, has operating current according in corresponding welding machine, is turned on and off high negative pressure blower fan 80 so that high negative pressure blower fan 80 keeps consistent with the duty of welding machine, reaches energy-conservation purpose.Pressure-sensitive switch 12 and electric current inductive switch 13 are designed with display screen, it is possible to check correlation values for operator.In the present embodiment, high negative pressure blower fan 80 is high negative pressure brushless fan, long service life.Speed governing knob 14 can make operator adjust the wind speed of high negative pressure blower fan 80 according to working condition, improves energy-saving effect further.
Being additionally provided with fast lock 15 on protecgulum 10, fast lock 15 can by equipment entirety quick locking by the mode of spinner, it is ensured that the sealing of effective filter 70, reduces the pressure loss of equipment.
Base plate 60 is provided with support tubes 71, support tubes 71 is movably arranged on the downside of effective filter 70, effective filter 70 is positioned and supports, simple in construction, support tubes 71 adopts bolt to fix and can dismantle, convenient effective filter 70 is keeped in repair and changed, people can regulate voluntarily, makes the effective filter 70 can with the miscellaneous part accurate contraposition in housing.
Being additionally provided with water-proof connector 21 on bonnet 20, the holding wire of power line and electric current inductive switch 13 passes housing through water-proof connector 21, makes portable high negative pressure weldering fume purifier realize remotely being connected with welding machine, keeps the duty synchronized.The outside of high negative pressure blower fan 80 is provided with deafener 81, to reduce the noise of work process high negative pressure blower fan 80.
