Description

SCR post-processes cylinder and connects sealing device
Technical field
The present invention relates to a kind of SCR to post-process cylinder, and specifically SCR post-processes cylinder and connects sealing device, belongs to Tail gas treatment system of diesel engine technical field.
Background technique
Increasingly strict with diesel engine emissions regulations, exhaust aftertreatment technology is the technical measures that must be used.And SCR Tail gas treatment device must connect DPF vent gas treatment cylinder to meet VI emissions requirements of state, DPF vent gas treatment cylinder it is basic Principle is to trap the carbon particle in vehicle exhaust by special structure design, needs regular regeneration.DPF vent gas treatment cylinder In order to meet passive regeneration demand, it is necessary to by barrel designs at Detachable connection structure, after connection structure disassembly assembling There is higher air-tightness requirement again.In the prior art, some post-processing cylinder connection structures are in order to guarantee that higher air-tightness is wanted Derivation causes disassembly inconvenient, and some post-processing cylinder connection structures are in order to guarantee that convenient disassembly affects sealing performance again.
Summary of the invention
It is an object of the present invention to overcome the above deficiencies, to provide a kind of SCR post-processing cylinder connection sealing dress It sets, can guarantee cylinder link position favorable sealing property, and can fast and easily realize disassembly.
According to technical solution provided by the invention, it includes DOC cylinder and DPF that SCR, which post-processes cylinder connection sealing device, Body, it is characterized in that: one circle hump pipe of DPF barrel outer surface welding, hump pipe are located at DPF cylinder connection DOC cylinder one end nozzle At position;DOC cylinder connection DPF cylinder one end nozzle is equipped with flanging section, and flanging section is socketed on DPF cylinder, and And flanging section is tightly attached to one side surface of hump pipe, flanging section is turned down from cylinder inner ring to cylinder outer ring direction;It is described to turn up Side section and hump pipe outer ring are equipped with anchor ear, and anchor ear is located at DPF cylinder side inner face and is pressed on hump pipe surface, and anchor ear is located at Flanging section is pressed on hump pipe surface by DOC cylinder side inner face.
Further, the hump height H of hump pipe is 5 ~ 50mm, and hump flaring angle γ is 90 ° ~ 150 °, the contracting of hump pipe Mouth section and flared section angle β are 0 ° ~ 90 °.
Further, DOC cylinder is equipped with flared section, and flared section connects flanging section by changeover portion, and changeover portion is flat Straight barrel structure.
Further, gasket seal is equipped between flanging section and hump pipe.
Further, the flange height g of flanging section is 5 ~ 50mm, and flange angle [alpha] is 90 ° ~ 150 °.
Compared with the prior art the present invention has the advantage that
The invention has the advantages of simple structure, compactness and reasonable structure, can guarantee cylinder link position favorable sealing property, and can be fast square Just realization disassembly.
Detailed description of the invention
Fig. 1 is main view of the present invention.
Fig. 2 is main view of the present invention.
Fig. 3 is main view of the present invention.
Description of symbols: 1-DOC cylinder, 2-DPF cylinder, 3- anchor ear, 4- hump pipe, 5- gasket seal, 6- flanging Section, 7- flared section, 8- changeover portion.
Specific embodiment
The present invention will be further described in conjunction with the embodiment in attached drawing below:
As shown in Fig. 1 ~ 3, the invention mainly comprises DOC cylinder 1 and DPF cylinder 2,2 outer surface of DPF cylinder welding, one circle hump pipes 4, hump pipe 4 is located at DPF cylinder 2 and connects at 1 one end nozzle position of DOC cylinder.
In the embodiment shown in fig. 3, the hump height H of the hump pipe 4 is 5 ~ 50mm, and hump flaring angle γ is 90 ° ~ 150 °, 4 necking section of hump pipe and flared section angle β are 0 ° ~ 90 °.
The DOC cylinder 1 connects 2 one end nozzle of DPF cylinder and is equipped with flanging section 6, and flanging section 6 is socketed in DPF cylinder 2 On, and flanging section 6 is tightly attached to 4 one side surface of hump pipe, and flanging section 6 is turned down from cylinder inner ring to cylinder outer ring direction.
The DOC cylinder 1 is equipped with flared section 7, and flared section 7 connects flanging section 6 by changeover portion 8, and changeover portion 8 is flat Straight barrel structure.
The flanging section 6 and 4 outer ring of hump pipe are equipped with anchor ear 3, and anchor ear 3 is located at 2 side inner face of DPF cylinder and is pressed on 4 surface of hump pipe, anchor ear 3 are located at 1 side inner face of DOC cylinder and flanging section 6 are pressed on 4 surface of hump pipe.
Gasket seal 5 is equipped between the flanging section 6 and hump pipe 4, gasket seal 5 can further increase flanging Sealing performance between section 6 and hump pipe 4.
In the embodiment shown in fig. 3, the flange height g of the flanging section 6 be 5 ~ 50mm, flange angle [alpha] be 90 ° ~ 150°。
The working principle of the invention is: in connection, the flanging section 6 of DOC cylinder 1 being socketed in DPF cylinder 2 first On, then flanging section 6 is pressed on hump pipe 4 by anchor ear, to realize that the sealing of DOC cylinder 1 and DPF cylinder 2 connects It connects.In disassembly, it is only necessary to unclamp anchor ear, it will be able to easily separate DOC cylinder 1 and DPF cylinder 2.
The invention has the advantages of simple structure, compactness and reasonable structure, can guarantee cylinder link position favorable sealing property, and can be fast Prompt convenient realize is dismantled.
