Abstract
The utility model relates to the technical field of three-way catalytic converters for purifying tail gas of motor vehicles, in particular to a modified metal carrier, which solves the technical problems of unreasonable design and the like of the prior art. The modified metal carrier comprises a cylindrical casing and a core arranged in the casing, and is characterized in that the core comprises a plurality of partition plates, the casing is equally divided into a plurality of sector areas by the partition plates, a plurality of radially distributed arc plates are arranged between each two adjacent partition plates, and a wavy bent plate is arranged between each two adjacent arc plates. Compared with the prior art, the modified metal carrier has the advantages of reasonable design, simple structure, easiness in processing and manufacturing, lower production cost, stable and reliable working performance and high mechanical strength.
Description
Technical field
The utility model relates to motor vehicle tail-gas purifying with three-element catalytic reforming unit technical field, especially relates to a kind of modified form metallic carrier.
Background technology
In the purifying vehicle exhaust gas system, catalyst carrier is the critical component of catalytic converter, and its material is pottery and two types on metal.Because ceramic monolith is little with respect to the metallic carrier geometric area, back pressure is high, thermal conductivity is low, thermal capacity is high, vibration resistance is poor; Under equal efficient; The converter volume is big, it is big to take up room; And metallic carrier has good electrical conductivity one and can realize electric preheating, the high back pressure when fundamentally having solved the ceramic monolith exhaust and when cold start-up the extremely low defect of discharging conversion ratio, so metallic carrier is superior to ceramic monolith.Existing in the market metallic carrier generally adopts dull and stereotyped rolling after overlapping with corrugated plating to form, and gas is shorter in the internal stops time: the geometric jacquard patterning unit surface utilization rate is low, causes catalytic conversion low.
For this reason, people have carried out long-term exploration, have proposed various solutions.For example, the Chinese patent document discloses a kind of outer three unique catalytic converter metallic carrier [application number: CN00243739.2] of machine of vehicles equipped with gasoline engine tail gas, by the corrugated alloy sheet of band ripple and the flat alloy thin slice is superimposed is rolled into; Adjacent two crest angles are 60 °-120 °; The ripple height on corrugated is 1-2.4mm, and going back punching press on it has another kind of ripple, and two kinds of ripple directions are different; Cross one another, there is pitting at the trough place of ripple also punching press.Increased the area of alloy sheet and the complexity of surface state like this, and then increased the adhesive capacity and the adhesive capacity of three-way catalyst, improved service life and effectively purified stroke.Such scheme has improved conversion ratio to a certain extent.But it is reasonable inadequately still to exist design, processing and manufacturing cost high-technology problem.
Summary of the invention
The purpose of the utility model is to the problems referred to above, provides a kind of reasonable in design, simple in structure, is easy to processing and manufacturing, and mechanical strength is high, the modified form metallic carrier of long service life.
For achieving the above object; The utility model has adopted following technical proposal: this modified form metallic carrier, comprise housing cylindraceous and the core body that is arranged in the housing, and it is characterized in that; Described core body comprises some dividing plates; Described dividing plate is divided into some sector regions with housing, between two adjacent dividing plates, is provided with some radially-arranged arcs, is provided with the bending plate of bending undulate between two adjacent arcs.
In above-mentioned modified form metallic carrier, described housing center is provided with newel, and described newel links to each other with bending plate on being arranged on the innermost layer arc.
In above-mentioned modified form metallic carrier, described arc is radially equidistantly distributing.
Compared with prior art, the advantage of this modified form metallic carrier is: reasonable in design, simple in structure, be easy to processing and manufacturing, and production cost is lower, stable and reliable working performance, and mechanical strength is high.
Description of drawings
Fig. 1 is the structural representation that the utility model provides.
Among the figure, housing 1, newel 10, core body 2, sector region 20, dividing plate 21, arc 22, bending plate 23.
The specific embodiment
As shown in Figure 1, this modified form metallic carrier comprises housing 1 cylindraceous and the core body 2 that is arranged in the housing 1.Core body 2 comprises some dividing plates 21, and described dividing plate 21 is divided into some sector regions 20 with housing 1, between two adjacent dividing plates 21, is provided with some radially-arranged arcs 22, is provided with the bending plate 23 of bending undulate between two adjacent arcs 22.Arc 22 is radially equidistantly distributing.Housing 1 center is provided with newel 10, and described newel 10 links to each other with bending plate 23 on being arranged on innermost layer arc 22.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as housing 1, newel 10, core body 2, sector region 20, dividing plate 21, arc 22, bending plate 23 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain the essence of the utility model more easily; It all is contrary with the utility model spirit being construed to any additional restriction to them.
