Description
Technical field
The present invention relates to a kind of cartridge types to post-process sealing structure, belongs to vehicle exhaust post-processing sealing structure technical field.
Background technique
Diesel emission standard is constantly being promoted, and DPF technology is more and more widely used in terms of exhaust aftertreatment, DPF
That is grain catcher captures particle, such as precipitin, inertia sedimentation or line by the filter device of surface and internal mix
Property intercept etc..
DPF key technology is to regenerate, and by actively or passively regenerating, will be deposited on the particle of catalyst surface and inner wall
Object is got rid of, and dpf regeneration is frequently necessary to us and individually removes the DPF section of preprocessor clean, so preprocessor
It is detachable to be designed as single hop more.
At hand, DPF technology has become diesel powered vehicles exhaust aftertreatment for diesel engine state six and non-rice habitats T4 regulation
Standard configuration.So a kind of simple and effective removable post-processing encapsulating structure, becomes particularly important.
The removable structure that the encapsulation of cartridge type post-processing at this stage uses is mostly following two:
(1), two flanges of male and female are welded on two cylinders, flange intermediate cryptographic gasket by flange hooping structure respectively, with embrace
Hoop is held tightly sealing；
(2), flange cylinder hooping structure, two sides cylinder carry out flange, and intermediate cryptographic gasket is held tightly with anchor ear and sealed.
The problem of flange anchor ear and flange cylinder hooping structure: 1, flange is machined piece, needs to be opened, expensive；2,
Hooping structure is complicated, at high cost；3, the fit dimension that cylinder flange needs is more demanding, and is easy cracking；4, both structures
Space utilization rate is lower, can waste one section of barrel lenght, not compact enough.
Summary of the invention
It is an object of the present invention to overcome the above deficiencies, to provide a kind of cartridge type post-processing sealing structure, structure
Compact, convenient for disassembly and assembly, space utilization rate is high, stable and reliable in work.
According to technical solution provided by the invention, a kind of cartridge type post-processing sealing structure includes conveyor front barrel, rear cylinder body and lock
Tight component, it is characterized in that: welding the retaining ring of L-shaped structure in the inner cavity of the rear cylinder body, described conveyor front barrel one end is equipped with necking section,
The necking section of conveyor front barrel is protruded into the cavity that rear cylinder body inner wall and retaining ring are formed and is held out against；The connection of the conveyor front barrel and rear cylinder body
Portion is equipped with multiple locking assemblies, and multiple locking assemblies link into an integrated entity conveyor front barrel and rear cylinder body.
Further, locking assembly includes front journal, rear trunnion, clamping screw and locking nut, before front journal is welded on
On cylinder lateral wall, rear trunnion is welded on rear cylinder body lateral wall, is connected between front journal and rear trunnion by clamping screw, lock
Tight bolt tail end connects locking nut, and locking nut locks front journal and rear trunnion integral.
Further, gasket seal is equipped between the necking section and retaining ring of conveyor front barrel.
Further, multiple locking assemblies are circumferentially uniformly distributed.
Compared with the prior art the present invention has the advantage that
The invention has the advantages of simple structure, compactness and reasonable structure, and connection amount of parts is few, and convenient for disassembly and assembly, the exceptional space occupied is less, system
Make that cost is relatively low, maintenance cost is lower, stable and reliable in work.
Detailed description of the invention
Fig. 1 is main view of the present invention.
Fig. 2 is A-A cross-sectional view in Fig. 1.
Description of symbols: 1- conveyor front barrel, 2- rear cylinder body, 3- gasket seal, 4- retaining ring, 5- necking section, 6- front journal, 7-
Trunnion, 8- clamping screw, 9- locking nut afterwards.
Specific embodiment
The present invention will be further described in conjunction with the embodiment in attached drawing below:
As shown in Figure 1 and 2, the invention mainly comprises conveyor front barrel 1, rear cylinder body 2 and locking assemblies.
The retaining ring 4 of L-shaped structure is welded in the inner cavity of the rear cylinder body 2, described 1 one end of conveyor front barrel is equipped with necking section 5, placket
The necking section 5 of body 1 is protruded into the cavity that 2 inner wall of rear cylinder body and retaining ring 4 are formed and is held out against.
Gasket seal 3 is equipped between the necking section 5 and retaining ring 4 of the conveyor front barrel 1, gasket seal 3 can be improved leakproofness
Energy.
The interconnecting piece of the conveyor front barrel 1 and rear cylinder body 2 is equipped with multiple locking assemblies, and multiple locking assemblies are by conveyor front barrel 1
It links into an integrated entity with rear cylinder body 2, multiple locking assemblies are circumferentially uniformly distributed.
The locking assembly includes front journal 6, rear trunnion 7, clamping screw 8 and locking nut 9, before front journal 6 is welded on
On 1 lateral wall of cylinder, rear trunnion 7 is welded on 2 lateral wall of rear cylinder body, passes through clamping screw 8 between front journal 6 and rear trunnion 7
Connection, 8 tail end of clamping screw connect locking nut 9, and locking nut 9 locks front journal 6 and rear trunnion 7 integrally.
The invention has the advantages of simple structure, compactness and reasonable structure, and connection amount of parts is few, and the exceptional space occupied is less, manufacturing cost
Lower, maintenance cost is lower, stable and reliable in work.
