DE3715040A1 - Punched strip catalyst - Google Patents

Abstract

The punched strip catalyst is fabricated from a material strip suitable for catalysts. The strip runs through a punch machine which punches through it in stressless form over the entire strip width and strip length and then coils it up like a clock spring. In a pipe or exhaust, also usable sequentially, in a similar manner to a screen, the punched strip catalyst, coated or uncoated, can also be used as a screen or mixer.

Description

I make claims for catalysts made by one punched tape that is wound like a clockspring, pressed in a pipe or exhaust, then like a sieve looks and can also be used as such.

The designation S.B. Catalytic converter (punching belt catalytic converter) indicates the form and nature of the subject matter of the patent application.

A belt suitable for the catalysts runs through the Punching machine and is separated into sections and opened wraps.

With tension-free punching from the bottom or top material is pressed out simultaneously with the perforations. The Z. B. enlarged rectangular material the surface, increases the efficiency and determines the Ab levels of the respective windings.

The S.B. Catalytic converter can be used for any exhaust system (chimney) or every vehicle type can be manufactured.

Punch depth and number of windings and springback determine its diameter.

The SB catalytic converter can be used one after the other in the required number (see drawing Fig. 3 - an exhaust with space for three SB catalytic converters CDE: they are pressed into the exhaust from the left through the conical part).

S.B. Catalysts can be admitted somewhat due to production press together and can therefore also via a Rohrver be pressed in. They spring up again and need then no more fortifications.

The hot exhaust gases are in the S.B. Catalyst constantly reversed leads, they come across this again and again during the punching process pushed out material, flow through the punch holes and the windings.

The claims relate to the properties and on the variety of uses; they do not apply to the Be layering, for materials, alloys, dies or Number of punches.  

I also make claims if the S.B. catalyst industrial as a sieve (vibrating sieve) or mixer, rotating or dormant for liquid, plastic or dry substances is used.

The S.B. is marked. Catalyst through the multitude its stampings over the entire length and bandwidth that is wound like a clock spring.

Then resembling a sieve in a pipe, chimney or exhaust and coated or uncoated, also as such ver can be applied.  

S.B. Catalysts are usable and adaptable more versatile than the well-known ceramic or sheet steel kata lysators.

The designation S.B. Catalyst indicates the type of production. A thin strip of material suitable for catalysts, runs through a punching machine from the roll is separated into individual pieces and subsequently wound up like a clock spring.

Also alloyed steel or metal, already separated into individual parts Tapes can be sprayed or dipped after the punching process be coated.

Through the punching across the entire bandwidth or length and at the edges in the most tensionless form possible, becomes band material depending on the punched down or pushed out. Soon the tape is punctured depending on the die shape.

The z. B. squeezed out rectangular material stand at a 90 ° angle to the belt, but at least a 45 ° angle to reach.

The punching sequence and the outstanding material associated with the ribbon increases the surface area, the efficiency determines the S.B. Kata lysators, apart from alloys and coatings. The pieces of material that protrude individually from the band fit into the Wind up in the respective gaps and determine by touching down about the number of windings after the manufacturing process spring open something.

The advantages of the S.B. Catalyst are in manufacturing and in the variety of uses. By the given punch depth, tape the S.B. Catalyst everyone Vehicle type, chimney or exhaust pipe can be made accordingly.

The S.B. Catalyst can also be run in series through a pipe Press in the constriction, spring open again and then do not need any other fastenings more.

Several SB catalysts can also be pressed in via a conical exhaust part (see drawing Fig. F.3) (see CDE Fig. F.3 with space for three SB catalysts).

S.B. pressed into a tube Catalysts see for the Be traditional looking like a sieve, exhaust gases flowing through change constantly their direction, are diverted, flow through the punch holes and windings.

This property makes the S.B. Catalyst too use industrially as a sieve. As a vibrating screen, rotating or dormant for liquid, plastic or dry substances.

The S.B. Catalyst is ideal for mixtures; Used in the pipe system, it can be expensive and space-consuming Save mixer.

Claims (4)

1. Catalyst, characterized in that it consists of a punched tape, which has tension-free punchings on the entire length and bandwidth from the bottom and / or top, through which material is pressed out to enlarge the surface, the tape being one Clock spring similarly wound and pressed into a pipe or exhaust. 2. A process for the preparation of the catalyst according to claim 1, characterized in that one for catalysts suitable tape runs through a punching machine and separates and winds it up. 3. Use of the catalyst according to claim 1 in exhaust gas lay (chimneys) and vehicles. 4. Use of the catalyst according to claim 1 as indu Strielle sieve (vibrating sieve) or as a mixer, rotating or dormant for liquid, plastic or dry Fabrics.
