Abstract
The present invention relates to engine exhaust pollution control technology field more particularly to a kind of catalyst technologies fields.The fixed catalyst converter of a kind of pin of the present invention, including support core and shell, the support core is located at the inside of shell, it is characterized in that, the catalyst converter further includes fixed pin, the hole being inserted into for pin is designed on the shell and support core, the pin is inserted into the hole on shell and across support core, and the pin is fixed together with shell by welding procedure.Catalyst converter of the present invention interts pin to be combined together with welded seal, and the fastness of fixed structure is higher, and technical process is simple, of low cost.
Description
Technical field
The present invention relates to engine exhaust pollution control technology field more particularly to a kind of catalyst technologies fields.
Background technology
Catalyst converter is the current main tool for solving engine exhaust control problem.The prevention problem of air pollution is always
Be badly in need of the worldwide problem solved, and one of main source of air pollution is exactly communications and transportation contact scar, i.e., automobile, train,
The tail gas of the discharges such as steamer and aircraft, wherein automobile discharge Tail Gas are nearest away from breathing zone, and can be directly sucked in by people, dirty
If contaminate owner's nitrogen oxides (NOx), hydrocarbon (HC), carbon monoxide (CO) and lead dust etc..These vehicles are usual
It is driven by internal combustion engine, fuel combustion generates various pollutants, and passes through physics or change before these pollutants are discharged into air
Method, which is handled, filters or is converted into harmless object by these pollutants, is the current main side for solving communications and transportation contact scar
Formula.Wherein, catalyst converter is the current main tool for solving engine exhaust control problem, and catalyst converter generally includes shell and coating
The support core of catalyst coat.
Catalyst converter is typically all to be made of support core and shell two parts, and support core is fixed on the inside of shell.At present, city
Support core and shell are mainly fixed together by the catalyst converter product on field using soldering processes.But soldering processes have centainly
The drawbacks of and limitation, this technique is higher to equipment requirement, and process costs are also higher, and the fastness of this fixed structure is not
It is high.
Present invention employs a kind of new support core and the fixed structure of shell, this structure being capable of reinforcing member connection jail
Soundness, and reduce technique cost of implementation.
Invention content
In view of above-mentioned technical problem exists in the prior art, it is close that support core of the present invention employs the welding of pin cross-linking
Support core and shell are fixed together by envelope mode, and this fixed structure is simple for process, and are had and be preferably connected firmly
Degree.The present invention specifically adopts the following technical scheme that.
Catalyst converter of the present invention, including support core and shell, the support core is located at the inside of shell, and feature exists
In the catalyst converter further includes fixed pin, and the hole being inserted into for pin, the pin are designed on the shell and support core
Nail is inserted into the hole on shell and across support core, and the pin is fixed together with shell by welding procedure.
Any mode that the fixed structure of catalyst converter of the present invention can be realized by those skilled in the art is complete
Into such as being completed by following processes：The shell of the catalyst converter is usually made of sheet metal, and the plank first passes through punching work
Skill is made by the hole being inserted into for pin, then edge rolling, and shell is finally made；It is also required to punch in advance on the support core, outside
After pouring into support core in shell, it is based on above-mentioned punching using drilling machine and support core is punched；Finally, pin is passed through into above-mentioned shell and load
Pin and shell are fixed together by the hole on body core by being welded sealing.
Catalyst converter of the present invention, during equipment, shell is in the preparation with regard to hole punch position first, secondly by support core
It is put into shell, and penetrates pin, finally, electric welding sealing, so as to which support core and shell are fixed together.This technique for fixing
Simply, it is of low cost, and comprehensive good cost performance.
Catalyst converter of the present invention has the advantages that：1st, pin interts and welded seal is combined together, fixed
The fastness of structure is higher；2nd, technical process is simple, of low cost.
Description of the drawings
Fig. 1 is the fixed structure schematic diagram of catalyst converter of the present invention.
In figure, 1 is shell, and 2 be support core, and 3 be pin.
Specific embodiment
Illustrate technical scheme of the present invention below in conjunction with the accompanying drawings, wherein, Fig. 1 is the fixed structure of catalyst converter of the present invention
Schematic diagram.
Catalyst converter as shown in Figure 1, including support core 2 and shell 1, the support core 2 is located at the inside of shell 1.It is described
Catalyst converter further includes fixed pin 3, and the hole being inserted into for pin, the pin 3 are designed on the shell 1 and support core 2
The hole be inserted on shell 1 and across support core 2, the pin 3 is fixed together with shell 1 by welding procedure.
Above example is merely illustrative of the invention's technical idea, it is impossible to protection scope of the present invention is limited with this, it is every
According to technological thought proposed by the present invention, any change done on the basis of technical solution each falls within the scope of the present invention
Within；The technology that the present invention is not directed to can be realized by the prior art.
