Abstract

The utility model relates to a device of vehicle catalyst which is convenient to disassemble and maintain, such as cleaning and replacing. The device provided a flexible and friendly system for customers. The utility model presents a multi-groupware device for catalyzing and filtering of exhausted gas, wherein, a detachable module which is consisting of entry module and exit module is provided. The catalyzer module and the filter module are arranged sequentially between the entry and exit module.

Description

The vehicle catalyst-assembly

Technical field

The utility model relates to a kind of vehicle catalyst-assembly.

Background technique

Be used for the lorry of diesel engine and the traditional filter and the catalyzer of passenger vehicle and be difficult to application maintenance because they normally independent one may be two maybe, make and must unload catalyzer and/or filter component is difficult.Thereby the system of any these parts of maintenance easy to use all has value, because just reduced the time that vehicle stops repairing like this.

The model utility content

The purpose of this utility model is to propose a kind of vehicle catalyst-assembly, and it has overcome above-mentioned shortcoming, be convenient to dismantle and safeguard, thereby by for example cleaning or replacing, for the user provides a flexibility and friendly system.The vehicle according to the invention catalyst-assembly is composed of multiple units, and comprises an inlet module, an outlet module, and be arranged on a catalyst module and a filter module between the entrance and exit module.These modules are columniform and are easy in a preferred embodiment dismantle.

Description of drawings

Fig. 1 is overall installation drawing;

Fig. 2 is the partial view of the circle part of Fig. 1; The details of having represented anchor clamps and insulation wall structure;

Fig. 3 has the preferred catalyst module of packing ring support shoulder or the end elevation of filter module, side view and partial view; With

Fig. 4 is get loose the fast end elevation and the side view of " V-arrangement " anchor clamps, and these anchor clamps are useful to the quick-release arrangement module.

Embodiment

Practical single catalyzer or a plurality of catalyzer in catalyst module, and practical filter is commercially available catalyzer and filter in the filtering module.Catalyzer can be the part filter, the part of the feasible exhaust of passing through is not filtered significantly, and catalyzer and filter one or both can be supported by the matrix of any kind, and this matrix comprises and flows through whole and " static mixer " or have the module of shunt.The present invention is not described in detail these parts.

As shown in Figure 1, inlet 1 and outlet 2 modules join in catalyst module 4 and the filter module 5 by the anchor clamps 3 that get loose fast, and the more details of these anchor clamps as shown in Figure 2.With reference to Fig. 2, these anchor clamps comprise an inner inverted V-arrangement assembly 6, and by the clamping of anchor clamps, this assembly can act on and each module is pressurizeed to next module and compress a seal washer 7.Can adopt multiple fastening device, comprise screw mechanism as shown in the drawing.

At least each catalyzer and filter module comprise an inner stainless steel wall 8 and also are stainless outer wall or outer shell, shown in detailed among Fig. 2.It is desirable to, the entrance and exit module is a same structure.What sandwich between inner and outer wall is isolation layer 10, as mineral fibre.Be in operation, all assemblies are in high-temperature, usually above 200-300 ℃.The design of this insulation can make injury with the contacted people of wall of this device for minimizing, simultaneously will be with the wall of this device the damage of other contacted or contiguous assembly minimize.This insulation form also can have the technical functionality of minimal thermal losses, and this point is even more important in cold weather.The catalysis that in catalyst module and filter module, takes place or the speed of uncatalyzed chemical process directly and the temperature correlation of these modules, and to maximize this speed be favourable.

Each module is desirable comprises upstanding flange 11, as Fig. 2 capitally shown in.This upstanding flange is acted on by the inversion V assembly 6 of the anchor clamps that get loose fast so that contiguous module is pressed onto together, and compression seal packing ring 7.One inner flange or shoulder 12 are fixed on the inner casing of one of module by welding or brazing, and this inner flange or shoulder are as the packing ring retaining ring.Its two ends of one of catalyst module and filter module have flange or shoulder 12 ideally, and only have upstanding flange 11 in abutting connection with module.Compressible packing ring 7 is supported by a packing ring retaining ring or shoulder 12, and packing ring 7 is compressed between two adjacent upstanding flanges after clamp.Provide similar device to come sealed entry and outlet module.Can effectively seal adjacent modules like this.

In fact individual module can be easy to assemble and seal, and can be disassembled and safeguard, for example by cleaning, or replaces, thereby a flexible and user-friendly system is provided.

Claims
