The purpose of this utility model is to provide a kind of box preprocessor, the structure design of the box preprocessor can be with
Convenient for the dismounting, maintenance and replacement of DOC unit.
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 3-Fig. 5 is please referred to, Fig. 3 is the structural schematic diagram of box preprocessor provided by the embodiment of the utility model, Fig. 4
For the explosive view of box preprocessor provided by the embodiment of the utility model, Fig. 5 is provided by the embodiment of the utility model box
The sectional view of preprocessor.
A kind of box preprocessor provided by the embodiment of the utility model, including cabinet, DOC unit 2 and DPF unit 4.
Wherein, DOC unit 2 and DPF unit 4 are all set in cabinet, the front end of DOC unit 2 and the front baffle 1 of cabinet
Connection, the rear end of DOC unit 2 are connect with the front end of DPF unit 4, and the rear end of DPF unit 4 and the rear bulkhead 7 of cabinet connect, and
Between DOC unit 2 and the front baffle 1 of cabinet, between DOC unit 2 and DPF unit 4 and the rear bulkhead 7 of DPF unit 4 and cabinet
Between be to be detachably connected.
Compared with prior art, box preprocessor provided by the utility model, when in use, DOC unit 2 and DPF are mono-
Member 4 can be dismantled individually, can also dismantle simultaneously.Convenient for the maintenance or replacement of DOC unit 2 and DPF unit 4.
Between DOC unit 2 and the front baffle 1 of cabinet, between DOC unit 2 and DPF unit 4 and DPF unit 4 and cabinet
Rear bulkhead 7 between can be accomplished in several ways and be detachably connected, for example be spirally connected, be clamped etc., implement in the utility model
In example, between the front baffle 1 of DOC unit 2 and cabinet, between DOC unit 2 and DPF unit 4 and after DPF unit 4 and cabinet
Fixed by clip between partition 7, clip be a kind of structure it is simple, convenient for the attachment device of operation, using such connection
When mode, it is only necessary to the boss or slot with clip cooperation be respectively set on two components interconnected.
Above-mentioned technical proposal is advanced optimized, according to the difference of position, the incomplete phase of the yoke configurations of position at above-mentioned three
Together, specifically, in the utility model embodiment, between the front baffle 1 of DOC unit 2 and cabinet and DPF unit 4 and cabinet
Rear bulkhead 7 between by V-type clip 3 connect, between DOC unit 2 and DPF unit 4 pass through flat clip 5 connect, it can be seen that,
It in the utility model embodiment, is used cooperatively using V-type clip 3 and flat clip 5, referring to Fig. 5, the DOC of 5 lower section of flat clip
There is the gap having a size of a between unit 2 and DPF unit 4；The flange of 3 lower section of V-type clip is in close contact.When post-processing work one
After the section time, because of high temperature action, the connection structure under V-type clip 3, which might have, to be partially sintered and more difficult disassembly, and flat clip 5
There are gaps for lower section, and easy-sintering, not can be convenient disassembly.When DOC unit 2 and DPF unit 4 have disassembly demand, Ruo Pingka
Hoop 5 is still arranged in 4 rear end of DPF unit as in the prior art, then the both ends of DOC unit 2 are all V-type clips 3, works normally
High temperature sintering make DOC unit 2 be difficult to dismantle, it is necessary to first dismantle DPF unit 4, DOC unit 2 dismantled after ability；And this is practical new
In type embodiment, flat clip 5 is arranged in centre, V-type clip 3 is arranged in both ends, makes DOC unit 2 and DPF unit 4 can
More conveniently dismantle.
Further, to be connect convenient for DOC unit 2 and DPF unit 4 with the front baffle 1 of cabinet or rear bulkhead 7, at this
In utility model embodiment, it is provided with mounting flange 6 on the front baffle 1 of cabinet and the rear bulkhead 7 of cabinet, DOC unit 2
Front end and the rear end of DPF unit 4 are provided with the boss for docking with mounting flange 6, clip by after docking boss with
Mounting flange 6 connects, and boss and mounting flange 6 cooperate with clip respectively.
Mounting flange 6 can be directly welded in the front baffle 1 or rear bulkhead 7 of cabinet, but will lead to mounting flange 6 after mounting
It can not replace, bore can not also be adjusted, for this purpose, mounting flange 6 is removably installed in a kind of embodiment of the utility model
The front baffle 1 of cabinet or the rear bulkhead 7 of cabinet, specifically, mounting flange 6 can be made of two parts, first part from cabinet every
Mounting hole on the side insertion partition of plate, second part be spirally connected from the other side of box partition and first part and with first
Distribution closes from two sides and clamps box partition, can be in this way, when needing replacing mounting flange 6, or when adjustment 6 bore of mounting flange
Mounting flange 6 is removed under the premise of not destroying cabinet.
Box post-processing unit further includes SCR unit other than above-mentioned DOC unit 2 and DPF unit 4, practical at this
In new embodiment, rear bulkhead 7 of the both ends of SCR unit respectively with the front baffle of cabinet 1 and cabinet is detachably connected.
Specifically, similarly with DOC unit 2 and DPF unit 4, in the utility model embodiment, SCR unit and case
Pass through clamp connection between the front baffle 1 of body and the rear bulkhead 7 of cabinet.
Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other
The difference of embodiment, the same or similar parts in each embodiment may refer to each other.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new
Type.Various modifications to these embodiments will be readily apparent to those skilled in the art, and determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
This, the present invention will not be limited to the embodiments shown herein, and is to fit to and principles disclosed herein
The widest scope consistent with features of novelty.
