Abstract

The utility model discloses a resoluble three-way catalyst. The resoluble three-way catalyst comprises a shell, a bedding arranged on the inner wall of the shell and an inner core built-in in the bedding, wherein a C-shaped sleeve is arranged between the bedding and the shell, the two ends of the shell are respectively connected with a front-end exhaust pipe and a rear-end exhaust pipe, the front-end exhaust pipe and the rear-end exhaust pipe and the shell are fastened through fastening members, and sealing gaskets are arranged between the front-end exhaust pipe and the rear-end exhaust pipe and the shell. The resoluble three-way catalyst provided by the utility model is convenient to produce and maintain, and all parts are likely to be separately recycled, so that the consumption on raw materials can be greatly reduced, the production cost and environmental pollution can be reduced.

Description

One can be decomposed ternary catalyzing unit

Technical field

The utility model relates to a kind of ternary catalyzing unit, relates in particular to a kind of ternary catalyzing unit that can decompose without damage part.

Background technique

Ternary catalyzing unit is the main parts size of Modern Internal-Combustion Engine emission control system, mainly by inner core, bed course, shell composition, it in use, inner core stops up, the catalyst converter of inner core is poisoning is most common failure, for this situation, in fact as long as change inner core, but existing ternary catalyzing unit, its inner core and housing can only destructive decomposition, assembling needs special device more, so when maintenance in, can only integral replacing, cause maintenance cost to increase, because destructive decomposition cost is higher, different materials part is also difficult to separate and reclaims, the raw materials consumption of industry is increased.

Model utility content

The purpose of this utility model is to overcome the defect of prior art, and a kind of ternary catalyzing unit that inner core and housing can be decomposed is mutually provided.

For achieving the above object, the utility model proposes following technological scheme:

One can be decomposed ternary catalyzing unit, comprise housing, be located at the bed course of inner walls and be built in the inner core in described bed course, between described bed course and described housing, be provided with C shape sleeve pipe, described housing two ends are connected with respectively front end outlet pipe and rear end outlet pipe, described front end outlet pipe and rear end outlet pipe are fastening by fastening piece and described housing, and are provided with sealing gasket between described front end outlet pipe and rear end outlet pipe and described housing.

Described C shape sleeve pipe is elastic stainless steel.

Described fastening piece is clip or bolt.

Compared with prior art, the decomposed ternary catalyzing unit that the utility model discloses, by elasticity C shape sleeve pipe is set between housing and bed course, can be by extruding C shape sleeve pipe to realize assembling and the decomposition of housing and inner core, in the time breaking down, without integral replacing, only need to change inner core and bed course, greatly reduce maintenance cost, easily realized Sorting Materials simultaneously and reclaim.

Accompanying drawing explanation

Fig. 1 is the sectional view that the utility model can decompose ternary catalyzing unit.

Embodiment

Below in conjunction with accompanying drawing of the present utility model, the utility model embodiment's technological scheme is carried out to clear, complete description.

As shown in Figure 1, the decomposed ternary catalyzing unit that the utility model discloses, specifically comprise housing 1, front end outlet pipe 2, rear end outlet pipe 3, C shape sleeve pipe 4, bed course 5 and inner core 6, described front end outlet pipe 2 is fastening with one end of described housing 1 by fastening piece 7, and be also provided with sealing gasket 8 between described front end outlet pipe 2 and described housing 1, described rear end outlet pipe 3 is same fastening with the other end of described housing 1 by fastening piece 7, and be provided with sealing gasket 8 between described rear end outlet pipe 3 and described housing 1, the coated described inner core 6 of described bed course 5, and be located at described housing 1 inside, described C shape sleeve pipe 4 is located between described bed course 5 and described housing 1.

Particularly, described C shape sleeve pipe 4 is elastic stainless steel, and described fastening piece 7 is clip or bolt.

In the time of assembling, first C shape sleeve pipe 4 is filled in housing 1, to after coated bed course 5 inner core 6, put into C shape sleeve pipe 4 again, or put into C shape sleeve pipe 4 after the coated inner core 6 of foreknowledge bed course 5, again entirety is filled in housing 1, while filling in, firmly pushed C shape sleeve pipe 4, enter after housing, under C shape sleeve pipe 4 elastic reactions, it is firmly stuck on the inwall of housing 1.

As needs teacher of the decomposition, first, by external strength tension and compression C shape sleeve pipe 4, it is separated with housing 1, then push C shape sleeve pipe 4 aside, bed course 5 and inner core 6 are therefrom separated.

The decomposed ternary catalyzing unit that the utility model discloses, assembling and decomposition do not need to weld and cut, and decompose to belong to without damaging and decompose, greatly reduce maintenance cost, be convenient to the recycling of part material simultaneously, reduced raw-material consumption, reduced cost and environmental pollution.

Technology contents of the present utility model and technical characteristics have disclosed as above; but those of ordinary skill in the art still may be based on teaching of the present invention and announcements and are done all replacement and modifications that does not deviate from the utility model spirit; therefore; the utility model protection domain should be not limited to the content that embodiment discloses; and should comprise various do not deviate from replacement of the present utility model and modifications, and contained by present patent application claim.
