Abstract
The utility model discloses a fire-proof device for the silencer of a motor vehicle exhaust gas, comprising an intake pipe, a sudden-expansion elliptical cylinder type calotte, an insertion groove and a filtering mechanism, wherein, exhaust flow is distributed and filtered by a mesh filtering mechanism which is composed of wire mesh at least two layers of mesh arranged in an intensive and staggered range, a sealing ring, a dividing post inserted in the middle through hole of the wire mesh, and a spring sheathed between the post sleeve and the dividing post; the sparks and the dust can be blocked with the dust removing rate reaching more than twenty percent, and the utility model has a positive meaning in purifying the air and protecting the environment. By using the fire-proof device, the power of the motor vehicle can be improved, the oil consumption and noise reduction can be lowered, and the utility model has the advantages of shock resistance, high temperature resistance, easy installation and long service life.
Description
The utility model relates to the improvement of the fireproofing installation of Motor Vehicle, especially a kind of refractory protection of automobile exhausting baffler, and it belongs to the fire-protection equipment field.
In the prior art, the automobile exhausting fire prevention apparatus of various patterns is arranged.The flameproof enclosure that a kind of muffler is arranged is equipped with the dish valve that the outer manual controlled handle of cover is controlled in its calotte cavity.Utilize the retaining fire aperture on the dish valve, under fire prevention exhaust work state, stop that Mars reaches the fire prevention purpose.Manual controlled handle control dish valve does not stop Mars under the normal exhaust state, just in case meet fire good, just can cause fire.Even there are not fire good, the drawback of exhaust contamination by dust air is arranged also.Moreover, the outer manual controlled handle butterfly-valve flameproof enclosure structure of this cover is complicated, trouble is installed in being provided with of manual controlled handle, manual mode operation also bothers in the using process, just in case forget out valve or close, will cause in fire prevention area because of the normal exhaust initiation fire, or increase exhaust resistance and exhaust voice at safe area because of the fire prevention exhaust, these the two kinds accidents that are due to all sorts of accidental mishaps take place.
The purpose of this utility model is the defective that will overcome the flameproof enclosure of above-mentioned muffler, and a kind of refractory protection of automobile exhausting baffler is provided.This device will have fireproof performance and also have dust removing effects, and simple in structure, and the formality that simplifies the operation once installing and using, does not need manual mode operation, reaches fire prevention, dedusting, safety, effect easily.
Task of the present utility model has following technological scheme to realize, developed a kind of refractory protection of automobile exhausting baffler, it comprises: by the fastening suction tude on baffler is given vent to anger the mouth of pipe of fixing clamp, the oval tubular calotte of the sudden expansion formula that is communicated with this pipe, be raised in the embedding slot of this calotte shell wall perpendicular to this setting at the major axis middle part of this calotte housing, be embedded with in this groove and have intensive staggered mesh filtering mechanism, the minimum area of the exhaust mesh of the logical current drainage of the permission of this mechanism and be greater than give vent to anger at least 0.5 times of the area of the mouth of pipe of this baffler.
The refractory protection of this automobile exhausting baffler, described mesh filtering mechanism, it comprises: the two-layer at least staggered silk screen of mesh collection, envelope is inlaid in the seal washer between this net and the embedding slot, be inlaid in branch fluidization tower in this net center through hole by column sleeve and seal washer thereof, be sleeved on the spring between this post and the column sleeve; The anterior fluoran stream surface that wherein divides fluidization tower is a circular cone dignity, or streamline dignity.
The refractory protection of this automobile exhausting baffler, the intensive staggered silk screen of described mesh, it can be a wire gaze, is preferably Stainless Steel Cloth.
The refractory protection of this automobile exhausting baffler, described minute fluidization tower, it can be a solid-cone fore-set body, also can be hollow cone fore-set body, can also be the hollow cone fore-set body on mesh surface.
Its advantage of refractory protection of the present utility model is: have intensive staggered mesh filtering mechanism owing to fixedly install in the oval tubular calotte of sudden expansion formula, this mechanism has stipulated minimum current drainage mesh area and at least 0.5 times of the area that is greater than the baffler air outlet again.This just makes air displacement can not be affected, and to improve the power of Motor Vehicle, reduces exhaust noise.Because having designed the anterior fluoran stream surface of branch fluidization tower is circular cone dignity or streamline dignity; make blast air along disperseing earial drainage to periphery through conical surface or streamiline surface; outflow velocity so just slows down; stop that Mars or dust remain in the mesh; the dust removal efficiency of this refractory protection reaches more than 20%, and this has the promotion meaning to the protection environment that purifies air.The branch fluidization tower that adopts is the hollow cone fore-set body on free heart vertex of a cone cylinder or mesh surface, and this has just alleviated the weight of this refractory protection and has reduced cost.This refractory protection has saved the operation manual controlled handle, is convenient to install, and is easy to use, and has the characteristics of high temperature resistant, anti-vibration, shock resistance, fire safety.
Embodiment of the present utility model is described below in conjunction with the accompanying drawings:
Fig. 1 is the refractory protection structure half sectional view of automobile exhausting baffler.
Fig. 2 is the refractory protection structure left view (the B-B view of Fig. 1) of automobile exhausting baffler.
Fig. 3 is the refractory protection structure right elevation (the A-A view of Fig. 1) of automobile exhausting baffler.
Referring to Fig. 1-3, this refractory protection includes: be fastened on give vent to anger suction tude 2 on the mouth of pipe of baffler 12, the oval tubular calotte 4 of the sudden expansion formula that is communicated with this pipe 2 by fixing clamp 1 by bolt 13.At these calotte 4 two halves embedding slots 5 fastening places by collet head 3 fastening calottes 4 in aggregates.Be raised in the embedding slot 5 of these calotte 4 shell walls perpendicular to this setting at the major axis middle part of these calotte 4 housings.Be embedded with in this groove 5 and have intensive staggered mesh filtering mechanism 6-11.The minimum area of the exhaust mesh of the logical current drainage of the permission of the 6-11 of this mechanism and wanting greatly less than give vent to anger 0.5 times of area of the mouth of pipe of this baffler.The filtering mechanism 6-11 of the design of this refractory protection, include: the intensive staggered silk screen 8 of five layers mesh (selecting Stainless Steel Cloth for use), envelope is inlaid in the asbestos sealing washer 9 between this net 8 and the embedding slot 5, be inlaid in branch fluidization tower 6 in these net 8 center through hole by column sleeve 7 and asbestos sealing washer 10 thereof, be sleeved on the spring 11 between this post 6 and the column sleeve 7,11 buffer functions of this spring, the intensity of reinforcement silk screen 8.Its minute, fluidization tower 6 was solid steel vertex of a cone cylinder, and the anterior fluoran stream surface of this post 6 is a circular cone dignity.
