Abstract
The invention relates to the technical field of diesel engine tail gas aftertreatment, in particular to a particulate trap assembling and disassembling structure which comprises a box body, an outer barrel and an inner barrel. The outer barrel is fixedly arranged in the box body, the inner barrel is arranged in the outer barrel in a matched mode, the circumferential surface of the outer barrel is provided with a plurality of pits, and the circumferential surface of the inner barrel abuts against the bottom faces of the pits; a DPF carrier is arranged in the inner barrel in a matched mode, and a shock pad is arranged between the DPF carrier and the inner barrel; a second porous flange is fixedly arranged at the front end of the outer barrel, a first porous flange is fixedly arranged at the front end of the inner barrel, and a graphite gasket is arranged between the first porous flange and the second porous flange. According to the particulate trap assembling and disassembling structure, the porous flanges and the graphite gasket are adopted for sealing, the sealing effect is excellent, and a DPF assembly can be prevented from axially moving; the inner barrel and the outer barrel of the DPF assembly are fixed through the pits to prevent the DPF assembly from circumferentially jumping. The structure is easy to assemble and disassemble, firm, reliable and low in cost.
Description
Technical field
The present invention relates to diesel engine vent gas post-processing technology field, specifically a kind of grain catcher is installed and detaching structure.
Background technique
Along with national exhaust gas from diesel vehicle pollutant emission standard is more and more stricter, new emission standard there has also been strict requirement to the particulate matter (PM) in exhaust pollutant, exhaust gas from diesel vehicle preprocessor installs DPF(grain catcher additional) really must go.But DPF needs regular dismounting blowback, to remove the insoluble granule that the soot particulate matter be collected in DPF, sulphate and ash particle etc. can not fall along with DPF hot recycling burn off.This just requires to need in reprocessing casing detachably at DPF.
The DPF of existing box reprocessing mode of taking out be that V-type anchor ear and flat anchor ear seal and fix substantially, and to uncap plate taking-up from body side, this kind of mode complex process, anchor ear used is single use, and cost is higher, and reprocessing box sizes can be caused to increase.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of grain catcher is provided to install and detaching structure, this device effectively can solve the sealing of grain catcher in reprocessing case and dismounting problem, can guarantee that the DPF in box diesel-oil vehicle reprocessing normally works in the product life cycle.
According to technological scheme of the present invention: a kind of grain catcher is installed and detaching structure, it is characterized in that: comprise casing, urceolus, inner core, described urceolus is fixedly installed in casing, inner core is equipped with in described urceolus, and pit is set at urceolus circumferential surface, inner core circumferential surface is resisted against pit bottom surface, DPF carrier is equipped with in inner core, between described DPF carrier and inner core, beam is set, described outer cylinder front end is fixedly installed the second porous flange, inner core front end is fixedly installed the first porous flange, between described first porous flange and the second porous flange, Graphite pad is set.
As a further improvement on the present invention, described inner core rear port is formed and closes up.
As a further improvement on the present invention, described first porous flange outer surface welding handle.
As a further improvement on the present invention, described casing front opening place is waled by sealing anchor ear.
As a further improvement on the present invention, described first porous flange, Graphite pad, the second porous flange three are bolted connection.
Technique effect of the present invention is: product of the present invention adopts porous flange and Graphite pad to seal, and sealing effect is outstanding, and DPF assembly can be stoped to move axially; DPF assembly inner/outer tube adopts several pit to fix, and stops its circumference to be beated; This structure dismounting is simple, solid and reliable, with low cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the sectional view of DPF assembly.
Fig. 3 is the stereogram of DPF assembly.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1 ~ 3, comprise sealing anchor ear 1, DPF assembly, casing 3, first porous flange 4, Graphite pad 5, second porous flange 6, urceolus 7, inner core 8, beam 9, pit 10, DPF carrier 11, handle 12, bolt 13 etc.
As shown in Fig. 1 ~ 3, the present invention is that a kind of grain catcher is installed and detaching structure, comprise casing 3, urceolus 7, inner core 8, described urceolus 7 is fixedly installed in casing 3, inner core 8 is equipped with in described urceolus 7, and pit 10 is set at urceolus 7 circumferential surface, inner core 8 circumferential surface is resisted against pit 10 bottom surface, DPF carrier 11 is equipped with in inner core 8, between described DPF carrier 11 and inner core 8, beam 9 is set, described urceolus 7 front end is fixedly installed the second porous flange 6, inner core 8 front end is fixedly installed the first porous flange 4, between described first porous flange 4 and the second porous flange 6, Graphite pad 5 is set.
Inner core 8 rear port is formed and closes up, and the first porous flange 4 outer surface welding handle 12, casing 3 front opening place is waled by sealing anchor ear 1, and the first porous flange 4, Graphite pad 5, second porous flange 6 three are fastenedly connected by bolt 13.
The assembling process of product of the present invention is as follows: before product mix is installed, first an appropriate location strokes per minute pit 10 on urceolus 7, then the second porous flange 6 has been welded with urceolus 7, then the second porous flange 6 has been welded on casing 3 together with urceolus 7, achieved a fixed connection.By DPF carrier 11 surface parcel beam 9, push in inner core 8, then the first porous flange 4 is welded together with inner core 8, then handle 12 is welded on the first porous flange 4, forms DPF assembly 2.
When mounted, open the sealing anchor ear 1 sealed for casing 3, Graphite pad 5 is placed on the second porous flange 6, and hole alignment, the DPF assembly 2 being welded with the first porous flange 4 is pushed in urceolus 7, make inner core 8 be close to pit 10, the first porous flange 4 aligns successively with the hole of Graphite pad 5 and the second porous flange 6, then tightens with bolt 13.
When dismantling, sealing clamp 1 need be dismantled, after then being dismantled one by one by bolt 13, taking out DPF assembly with special tool.
