Abstract
The utility model relates to a disassembly silencing filter in exhaust pipes, comprising a housing and a silencing filter. The utility model is characterized in that the silencing filter is in screw connection in the housing connected in the middle of the exhaust pipe to make the silencing filter replaced easily.
Description
The utility model is about noise reduction of using in a kind of outlet pipe and filter, particularly about dismountable noise reduction and filter in a kind of outlet pipe.
Press, the noise reduction and the filter of use all are to be fixed together with this outlet pipe in the existing steam turbine vehicle exhaust pipe, in case it is too much that this noise reduction and filter accumulate dirt, can produce a back pressure and force engine horsepower to lower, severe patient even make engine be difficult for starting, or flame-out easily.Moreover, whole noise reduction and filter need be changed together with whole outlet pipe when being changed after the long-term use of this noise reduction and filter, extremely uneconomical.
Edge is event, and this creator is improved with the shortcoming that noise reduction and filter can't separate existing outlet pipe, just has a creation that conforms with practicality to propose.
The purpose of the utility model is to provide disconnectable noise reduction and filter in a kind of outlet pipe.
The outlet pipe that provides a kind of cost low is provided another purpose of the utility model.
The purpose of the utility model can be via detachably changing the formula noise reduction in the following outlet pipe and filter is reached, and it comprises: a shell and a noise reduction and filter; It is characterized in that screwing togather in this shell in the middle of being connected in this outlet pipe this noise reduction and filter so that this noise reduction and filter are easy to change.
Wherein this shell comprises:
-the first outer tube;
-the second outer tube, it is welded in one of this first outer tube end; And
-conical pipe, its big end is welded in the other end of this first outer tube, and small end is connected with this outlet pipe.
And wherein this first outer tube comprises:
-base is welded in this first outer tube of this first outer tube and the big end of this conical pipe connecting part;
-central shaft, between its end was welded among this base, in order to support this noise reduction and filter, the other end then had screw thread;
-deck is welded in this first outer tube of this first outer tube and this second outer tube connecting part; And
-retaining ring, it is seated at mat on the screw thread that simultaneously it is screwed together in this central shaft of this deck to prevent that this noise reduction and filter from deviating from.
Moreover this noise reduction and filter comprise:
-quill shaft;
A plurality of arc iron plates, its interlaced mutual apportion ground is welded on this quill shaft with an end; And
A plurality of asbestos cloths are engaged on these a plurality of arc iron plates, in order to abate the noise and filtering exhaust in dirt, perhaps, this noise reduction and filter comprise:
-quill shaft;
-spirality iron plate, it is welded on this quill shaft; And
-asbestos cloth, it is engaged on this quill shaft according to spirality.
For structure, characteristics and the effect that makes the utility model can more clearly reveal, conjunction with figs. describes in detail as the back now:
Fig. 1 is dismountable noise reduction and a filter in the outlet pipe of the present utility model, first embodiment's decomposing type stereogram when being used for locomotive;
Fig. 2 is the constitutional diagram when dismountable noise reduction and filter are used for locomotive in this practical outlet pipe;
Fig. 3 is the stereogram of the employed spiral noise reduction of second embodiment and filter when dismountable noise reduction and filter are used for locomotive in the comb of the present utility model; And
Fig. 4 is the constitutional diagram when dismountable noise reduction and filter are used for automobile in the outlet pipe of the present utility model.
Dismountable noise reduction and filter mainly comprise a shell and a noise reduction and filter in the outlet pipe of the present utility model, and they are connected in the middle of this outlet pipe, and wherein this noise reduction and filter can be installed in this shell with screw, so that dismounting.
Please refer to Fig. 1, first embodiment when the utility model is used for locomotive, wherein shell 1 comprises the first outer tube 1a, the second outer tube 1b and a conical pipe 1c, weld a base 2 at one of this first outer tube 1a end earlier before this first outer tube 1a and this second outer tube 1b and this conical pipe 1c welding, a central shaft 3 is welded in the centre among this base 2 then, this central shaft 3 is provided with screw section 3a with respect to these base 2 ends, this screw section 3a protrudes in the first outer tube 1a slightly and extends to the second outer tube 1b, be provided with an annular deck 4 at this first outer tube 1a inner edge with respect to these base 2 places, after this first outer tube 1a moulding, the more big end of this conical pipe 1c is welded on base 2 ends of this shell 1, and this second shell 1b is welded on annular deck 4 ends of this first outer tube 1a, so form one complete outside shell 1.
Noise reduction of the present utility model and filter 5 comprise a quill shaft 5a, a plurality of arc iron plate 5b and a plurality of asbestos cloth 5c(or glass wool, ceramic wool, iron filings).Be that each arc iron plate that a plurality of arc iron plate 5b are divided into two row up and down and two row is welded on this quill shaft 5a when it is made interlacedly, be installed on these a plurality of arc iron plate 5b with screw fixed elements such as (or) iron nets 7 with the asbestos cloth 5c of equal number then.
When this noise reduction and filter 5 are placed in this shell 1 with this quill shaft 5a among during axle 3, because this central shaft 3 has screw section 3a, therefore but the hole 8a of this noise reduction and filter 5 mat retaining rings 8 passes the deck 4 that this screw section 3a is seated at this shell 1, and among being fixed in this noise reduction and filter 5 in this shell 1 with a nut 9 on the axle, the structure that this noise reduction and filter 5 and this shell 1 make up the back as shown in Figure 2.
Noise reduction of the present utility model and filter also can use another kind of form to replace, as scheme shown in Figure 3, fixing a cotton 10 with screw 7 again behind spirality iron plate 5d of weldering on the quill shaft 5a of equal length, so can cause exhaust to discharge outlet pipe according to helical.
Please refer to Fig. 4, the utility model can add a taper tail pipe 12 when being applied on the outlet pipe of automobile, adding weldering one first pedestal 13 on the edge outside this shell 1 close second outer tube 1b in addition, two hole (not shown)s on this pedestal become 180 ° to stand far apart facing each other, when the two hole (not shown)s of the second pedestal 2a of this taper tail pipe 12 with promptly can two bolts 14 after two holes of this first pedestal 13 align mutually and two nuts 15 be fixed together.
In the time need changeing this noise reduction and filter, can or be upgraded noise reduction and filter extraction inspection as long as unclamp bolt 14 and nut 15 and shell 1 interior nut 9.
In sum, the effect that the utility model had is that dismountable noise reduction formula filter can remove inspection in use for some time and whether have dirt to accumulate, thereby can avoid influence horsepower, utmost point noise reduction easily and filter so the utility model can be said so.
Again because of outlet pipe if when breaking down, whole outlet pipe need do not changed, load onto one again as long as this noise reduction and filter changed, so can reduce the maintenance expenses of locomotive.
Though the utility model discloses as above with a preferred embodiment; right its is not in order to limit the utility model; anyly have the knack of this skill person; in the spirit and scope that do not break away from the utility model; change and retouching when doing some, so the protection domain of the utility model attached claim person of defining after looking is as the criterion.
