Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
As shown in Figure 1-Figure 3, the Pneumatic cleaning device of DPF cleaning machine, including Pneumatic cleaning dress is driven for providing gas
The Pneumatic assembly of work is set, Pneumatic assembly includes fixed bin 1.It is socketed with control shaft 2 in the middle part of fixed bin 1, is arranged at the top of control shaft 2
There is high-pressure pipe 3.2 bottom side of control shaft is fixedly connected with the second belt pulley 4, and the second belt pulley 4 is combined with belt 5, skin
5 other side of band is combined with the first belt pulley 6, and the first belt pulley 6 is fixedly connected with pneumatic stepping motor 7.2 second belt of control shaft
Wheel 4 is fixedly connected with fixed plate 8, and fixed plate 8 is fixedly connected with air jet pipe 9.Air jet pipe 9 is fixedly connected with operated pneumatic valve 10, gas
Movable valve 10 is fixedly connected with gas storage box 11.Gas storage box 11 is fixedly connected with high-pressure air pipe 12.More than 12 high pressure admission of high-pressure air pipe
Pipe 3 connects.By high-pressure pipe 3 into control shaft 2 conveying high-pressure gas.High pressure gas enters jet by control shaft 2
In pipe 9, jet assembly carries out high pressure qi of chong channel ascending adversely to DPF, and the particulate matter of DPF attachment is blown out.
Wherein, the setting of gas storage box 11 is so that high pressure gas is introduced into gas storage box 11 by high-pressure air pipe 12, gas storage
Gas in box 11 keeps high pressure conditions, so that the gas pressure of output air jet pipe 9 keeps stablizing.Gas storage box 11 if it does not exist,
It will lead to high pressure gas to enter directly into air jet pipe 9.When the blowout of 9 mesohigh gas of air jet pipe, high-pressure air pipe 12 and jet
There can be the vacuum state of certain time inside pipe 9, subsequent high pressure gas filling needs certain time, so that air jet pipe 9 is blown out
Gas pressure it is unstable, influence cleaning effect.
8 side of fixed plate is provided with guide rail 13, and the cooperation of guide rail 13 slidably connects sliding block 14.Sliding block 14 is fixedly connected with gas
Dynamic stepper motor 15.Pneumatic 15 1 side bottom of stepper motor is fixedly installed gear (not shown), and gear is engaged with rack 16.
Wherein, rack 16 is fixedly connected with fixed plate 8.When the work of pneumatic stepper motor 15, gear rotation will drive.Gear rotation
Drive rack 16 mobile.Rack 16 is mobile to drive the movement of fixed plate 8, so that air jet pipe 9 be driven to move along 13 direction of guide rail
Dynamic certain distance achievees the purpose that the position for adjusting air jet pipe 9.
Optimization, control shaft 2 is connected with movable plate 17 by bearing.There are two piston 18, pistons 18 for the abutting of movable plate 17
It is fixedly connected with cylinder.19
The course of work:
As shown, DPF is placed in DPF cleaning machine complete machine in the case of complete machine.At this point, when pneumatic cleaning device is started to work
When, the position of air jet pipe 9 is adjusted to the outer edge position of DPF by high pressure stepper motor, then passes to gas.Gas is logical
High-pressure pipe 3 is crossed to enter in control shaft 2.Gas in control shaft 2 enters in gas storage box 11 along high-pressure air pipe 12.Benefit
Pressure is kept to stablize with gas storage box 11, the high pressure gas in gas storage box 11 is entered in air jet pipe 9 by operated pneumatic valve 10, thus
Gas is sprayed into the impact upper surface DPF, so that the particulate matter of DPF inner surface and DPF are detached from.At the same time, pneumatic stepping motor 7
The first belt pulley 6 is driven to rotate.First belt pulley 6 drives belt 5 to move, to drive the rotation of the second belt pulley 4.Second belt
4 rotation of wheel drives control shaft 2 to rotate.It is non-at this time since air jet pipe 9 is in the outer peripheral position DPF when control shaft 2 rotates
In center, so that air jet pipe 9 is enclosed around center rotating around DPF outer edge one, outer ring cleaning is carried out to DPF outer edge.
After a week, pneumatic stepping motor 7 inverts for rotation, prevents high-pressure air pipe 12 from knotting.
Later, pneumatic stepper motor 15 works, and band moving gear rotates.Gear rotation driven gear bar 16 is mobile, thus band
Dynamic fixed plate 8 moves a certain distance, which is less than 9 diameter of air jet pipe.Fixed plate 8 is mobile to drive air jet pipe 9 towards the center DPF
Mobile same distance.It repeats the above steps, pneumatic stepping motor 7 drives air jet pipe 9 to surround DPF center rotating, to DPF outer edge
Internal certain distance is cleaned.After above steps may be repeated multiple times, the surface DPF is cleaned up completely, at this point, at air jet pipe 9
In DPF center position.
When each 9 jet of air jet pipe is completed, cylinder drives movable plate 17 to move up a displacement, so that jet
Pipe 9 is no longer contacted with the surface DPF, when air jet pipe 9 rotate a low-angle another place position is cleaned when, cylinder to
Lower movement one displacement, so that air jet pipe 9 is abutted with DPF and cleaned.By the setting, prevent air jet pipe 9 directly with DPF table
It is mobile when face contact, abrasion air jet pipe 9 is prevented, the service life of air jet pipe 9 is extended.
Overall effect:
The present invention is by above-mentioned setting, and entire cleaning process passes through high pressure gas completely and cleaned, and equipment mechanism is uncomplicated, and
And comprehensive cleaning can be carried out to DPF, under the control of PLC program, entire work is orderly carried out.Without cleaning solution energy
Enough realize preferable cleaning effect, and cost is relatively low.
