Abstract
A catalytic converter mainly comprises a front end cone, a housing and a rear end cone which are connected in sequence, and a carrier and a liner are arranged in the housing. The catalytic converter is characterized in that a first lathedog is arranged, and the front end cone and the housing are connected through the first lathedog; further, a second lathedog is arranged, and the rear end cone and the housing are connected through the second lathedog; and the catalytic converter carrier adopts porous medium, specifically ceramic material. Since the end cones and the housing are connected through the lathedogs in the structure of the catalytic converter, the end cones and the housing can be dismounted randomly. Therefore, the cleaning problem after the blockage of the catalytic converter is solved, and the cost is reduced because the end cones are saved even when the catalytic converter is replaced.
Description
Technical field
The utility model relates to a kind of catalyst converter that engine exhaust pollutes of eliminating.
Background technique
Country requires more and more higher to motor vehicle emission, to the also raising thereupon of requirement of catalyst converter.Catalyst converter need guarantee high transformation efficiency.Along with catalyst converter increases service time, the impurity in the vehicle exhaust can reduce conversion efficiency of catalytic converter attached to the catalyst converter carrier surface, causes discharging not reach laws and regulations requirement.
At present, automobile-used ceramic monolith catalyst converter mainly is made up of end awl 1, housing 3, liner 4, carrier 5, and the end awl adopts weld seam 2 welding manners to be connected (as shown in Figure 1) with housing.The catalyst converter carrier is porous medium and is stupalith.When engine failure or fuel qualities are not good, cause that easily carrier ablates or stop up.Its deficiency is, conventional catalyst device Placement is unfavorable for the cleaning of carrier surface impurity, and the catalyst converter that just need more renew this moment causes very big waste; In addition, when the catalyst converter carrier damages because of certain reason, in the time of must changing catalyst converter, conventional catalyst device structure must the end awl and housing change together, this also is a kind of waste.
The model utility content
The purpose of this utility model provides a kind of catalyst converter, solves catalyst converter dismounting problem.And be convenient to clean catalysis device carrier and repair and replacement catalyst converter.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of catalyst converter, and mainly being linked in sequence by front end awl, housing and rear end awl forms; Comprise carrier and liner in the housing; It is characterized in that: first clip is set, described front end awl and housing first clip connected.
Further, second clip is set, described rear end awl and housing second clip connected.
Described catalyst converter carrier is a porous medium.Described porous medium is a stupalith.
The beneficial effects of the utility model: adopt the clip connected structure because the utility model catalyst converter structure end awl is connected with housing, end awl and housing can arbitrarily be dismantled, effectively solved the cleaning after catalyst converter stops up, also can save the end awl, reduced cost even change catalyst converter.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is a prior art catalyst converter structure cutaway view.
Among the figure: 1. end awl, 2. weld seam, 3. housing, 4. liner, 5. carrier.
Fig. 2 is a catalyst converter organigram of the present utility model.
Among the figure: 1. front end awl, 2. housing, 3. rear end awl, 4. first clip, 5. first clip.
Embodiment
The utility model using method, catalyst converter front end and back end awl respectively increases a clip with the housing joint, utilizes clip will hold awl and housing chucking, utilizes interference fit to reach sealing and fixing.When catalyst converter stops up or need cleaning, clip is unclamped taking-up catalyst converter carrier can clear up easily.Improved catalyst converter utilization ratio again, provided cost savings.After the fragmentation of catalyst converter carrier, also only need provide for simple replacement of the catalyst converter carrier and get final product, can save and change end awl cost.
Claims (4)
1. catalyst converter, mainly being linked in sequence by front end awl, housing and rear end awl forms; Comprise carrier and liner in the housing; It is characterized in that: first clip is set, described front end awl and housing first clip connected.
