Abstract
The utility model relates to a silencer for automobiles, which comprises an outer casing and a silencing and smoke-eliminating device which is composed of fixed plates, a reinforced pipe, and gas guide pipes, wherein, two fixed plates are respectively perpendicular to the axial direction of the outer casing, and are fixedly connected with the outlet and the inlet of the outer casing; the reinforced pipe and the gas guide pipes are all parallel to the axial direction, and are connected between two fixed plates; high-temperature resistant fine wires which are helically arranged are arranged in the gas guide pipes. The utility model has the advantages of reasonable structure, simplicity, and low cost, and is applicable to the automobiles with lead-containing gasoline or with leadless gasoline. The silencing and the smoke-eliminating effects of the foreign silencers can be achieved by the installation of the utility model on foreign automobiles.
Description
The utility model relates to a kind of baffler, comprises shell and is installed in its cavity interior noise reduction, smoke abatement apparatus.
The baffler that a large amount of foreign car of present China import is furnished with is as noise reduction, smoke elimination filter core with three raw catalyst materials.When car used unleaded gas, its effect was rather good.But when using the doped fuel of China, the filter core of this baffler will be by refuse filling in the tail gas and ineffective.
The utility model purpose is: overcome the deficiency of prior art, provide a kind of foreign car that can be to be equipped with the mobile muffler of efficiently noise reduction when using unleaded or doped fuel, smoke elimination.
The utility model implementation is as follows: same as the prior art, it also comprises shell and is installed in its cavity interior noise reduction, smoke abatement apparatus, but its characteristics are: noise reduction, smoke abatement apparatus are made up of fixed plate, reinforcing pipe and air pipe.Two fixed plates respectively perpendicular to enclosure axis to, affixed place, entry and exit in the enclosure, reinforcing pipe is connected between two fixed plates, air pipe be parallel to shell axially-aligned, two ends pass the fixed plate at entry and exit places respectively and expose, have some open-works on the sidewall of the air guide tube head that exposes the ingress, air pipe is built-in with spiral-distributed high temperature resistant fine wire.
The utility model can be designed to: have two air pipes.
During with above-mentioned scheme implementation the utility model, can adopt hot water radiation wire for the wire that is provided with in the air pipe.In addition, also can on the guiding pipeline section between two fixed plates, superscribe one deck asbestos.
The utility model advantage is: it is rational in infrastructure, and manufacturing process is simple, cost is low; No matter automobile uses unleaded or doped fuel, and it can both finish noise reduction, the smoke elimination function; Attach it on the external automobile, can reach the work effect of external baffler.
Fig. 1 is the utility model embodiment general structure schematic representation.
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Below in conjunction with drawings and Examples the utility model is described further:
As shown in the figure, the utility model is made up of the resistance wire 5 in shell 1, two air pipes 2,9, reinforcing pipe 3, inlet fixed plate 7, outlet fixed plate 8, the air pipe, the asbestos clothing 6 of air pipe outer wrapping in an embodiment.
Working principle of the present utility model is: spray into the inlet of baffler when vehicle exhaust after, at first directly pounces on the fixed plate 7, thereby owing to the effect of 3 pairs of plates 7 of reinforcing pipe, make its vibration drop to minimum certain noise of eliminating; Tail gas all enters in two air pipes 2,9 from the port of tube head 4,10 and the open-work of surveying on the wall in the baffler entrance cavity gradually; The resistance wire 5 of pipe in 2,9 self line footpath is very thin, shape is being arranged in the shape of a spiral again, so the gas that passes in the pipe is not formed obstruction; The tail gas of high temperature is very fast promptly can be red with resistance wire 5 " burning ", and " burning " red resistance wire 5 will burn to the tail gas through air pipe 2,9 again, and the flammable one-tenth that it is contained prevents becoming harmless CO
2Gas, thus reach smoke elimination effect to tail gas; Being wrapped in the outer asbestos clothings 6 of air pipe 2,9 can eliminate the tail gas of high pressure most ofly and enter caused noises in the pipe 2,9.
Claims (4)
1, a kind of mobile muffler, comprise shell and be installed in its cavity interior noise reduction, smoke abatement apparatus, its spy is just: noise reduction, smoke abatement apparatus are made up of fixed plate, reinforcing pipe and air pipe, two fixed plates respectively perpendicular to enclosure axis to, affixed place, entry and exit in the enclosure, reinforcing pipe is connected between two fixed plates, air pipe is parallel to shell axially-aligned, two ends and passes respectively on the sidewall of the air guide tube head that fixed plate exposes, expose the ingress at entry and exit places and have some open-works, and air pipe is built-in with spiral-distributed high temperature resistant fine wire.
2, mobile muffler according to claim 1 is characterized in that: have two air pipes.
3, mobile muffler according to claim 1 and 2 is characterized in that: the wire that is provided with in the air pipe adopts hot water radiation wire.
