Abstract
The utility model relates to an accelerant silencer, which comprises a front housing, a rear housing, a middle clapboard, an accelerant fixing cover and an exhaust pipe, wherein the middle clapboard is arranged between the front housing and the rear housing; an air inlet chamber is formed between the front housing and the middle clapboard; an exhaust chamber is formed between the rear housing and the middle clapboard; the front housing is provided with an air inlet which is communicated with the air inlet chamber; the accelerant fixing cover is arranged in the air inlet chamber and on the side of the middle clapboard; an accelerant chamber is formed between the accelerant fixing cover and the middle clapboard; an accelerant is arranged in the accelerant chamber; an air outlet which is communicated with the exhaust chamber is arranged on the middle clapboard and is opposite to the accelerant chamber; the exhaust pipe is arranged on the rear housing; an air guiding cover is also arranged in the exhaust chamber opposite to the accelerant chamber and is hermetically connected with the middle clapboard; and the exhaust pipe extends into the exhaust chamber and is hermetically connected with the air guiding cover. According to the accelerant silencer, the temperature of the shell is low in the operating process, so that the arrangement of the accelerant silencer and components at the periphery of the accelerant silencer is compact, the size of an engine is reduced, and a silencing effect is enhanced effectively.
Description
Technical field
The utility model relates to the technology of gasoline engine field, is specifically related to a kind of catalyst baffler.
Background technique
In the prior art, the catalyst baffler of miniature gasoline engine is usually by front end-cover, rear casing and central diaphragm consist of, central diaphragm is arranged between front end-cover and the rear casing, form suction chamber between front end-cover and the central diaphragm, form exhaust chamber between rear casing and the central diaphragm, be provided with the catalyst fixed cover in the suction chamber, the catalyst fixed cover is arranged at the side of central diaphragm, form catalyst chamber between catalyst fixed cover and the central diaphragm, be provided with catalyst in the catalyst chamber, central diaphragm is provided with the air outlet that is communicated with exhaust chamber over against catalyst chamber, outlet pipe is arranged on the rear casing, and outlet pipe is communicated with exhaust chamber.During work, enter from the suction port of front end-cover and to enter in the exhaust chamber after high-temp waste gas in the suction chamber is processed through catalyst, the high-temp waste gas in the exhaust chamber is constantly given the shell transferring heat of baffler in the process of discharging, so that the extreme temperatures of the shell of baffler.Be the impact on its circumferential component of the shell high temperature in the course of the work that prevents baffler, the circumferential component that must guarantee baffler when designed engines is away from baffler, so that the erasure effect of the motor of designing is poor, build is excessive.
The model utility content
The deficiency that the utility model exists in order to overcome prior art provides a kind of structure more rational catalyst baffler, and this catalyst baffler is lower in the temperature of the process housing of work, and circumferential component need not be away from this catalyst baffler.
The utility model is achieved through the following technical solutions: a kind of catalyst baffler, comprise front end-cover, rear casing, central diaphragm, catalyst fixed cover and outlet pipe, described central diaphragm is arranged between described front end-cover and the described rear casing, form suction chamber between described front end-cover and the described central diaphragm, form exhaust chamber between described rear casing and the described central diaphragm, described front end-cover is provided with the suction port that is communicated with described suction chamber, described catalyst fixed cover is arranged in the described suction chamber, described catalyst fixed cover is arranged at the side of described central diaphragm, form catalyst chamber between described catalyst fixed cover and the described central diaphragm, be provided with catalyst in this catalyst chamber, described central diaphragm is provided with described exhaust chamber over against described catalyst chamber and is communicated with the air outlet, described outlet pipe is arranged on the described rear casing, also be provided with wind scooper over against described catalyst chamber in the described exhaust chamber, this wind scooper and described central diaphragm are tightly connected, and described outlet pipe stretches in the described exhaust chamber and is tightly connected with this wind scooper.
The beneficial effects of the utility model are: during work, enter in the wind scooper behind high-temp waste gas and the catalyst catalytic combustion that is fixed in the suction chamber, discharged again extraneous by outlet pipe, in whole working procedure of the present utility model, high-temp waste gas does not directly contact shell, this can prevent effectively that the skin temperature of baffler is too high, make the baffler circumferential component not be subjected to temperatures involved, this can make the compacter of the utility model and the setting of its circumferential component, the build of motor is reduced, and erasure effect effectively strengthens.
Description of drawings
Fig. 1 is Facad structure schematic diagram of the present utility model;
Fig. 2 be Fig. 1 B-B to cross-sectional view;
Fig. 3 be Fig. 1 C-C to cross-sectional view.
In the drawings: the 1-rear casing; The 2-outlet pipe; The 3-wind scooper; The 4-central diaphragm; The 5-front end-cover; The 6-inlet flange; 7-catalyst fixed cover; 8 catalyst.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
As shown in Figure 1-Figure 3, a kind of catalyst 8 bafflers, comprise front end-cover 5, rear casing 1, central diaphragm 4, catalyst fixed cover 7 and outlet pipe 2, central diaphragm 4 is arranged between front end-cover 5 and the rear casing 1, form suction chamber between front end-cover 5 and the central diaphragm 4, form exhaust chamber between rear casing 1 and the central diaphragm 4, front end-cover 5 is provided with the suction port that is communicated with suction chamber, catalyst fixed cover 7 is arranged in the suction chamber, catalyst fixed cover 7 is arranged at the side of central diaphragm 4, form catalyst Room 8 between catalyst fixed cover 7 and the central diaphragm 4, these catalyst 8 indoor catalyst 8 that are provided with, central diaphragm 4 is provided with exhaust chamber over against catalyst Room 8 and is communicated with the air outlet, outlet pipe 2 is arranged on the rear casing 1, it is characterized in that: also be provided with wind scooper 3 over against catalyst Room 8 in the exhaust chamber, this wind scooper 3 is tightly connected with central diaphragm 4, and outlet pipe 2 stretches in the exhaust chamber and is tightly connected with this wind scooper 3.
During work, the high-temp waste gas of discharging in the cylinder body enters in the suction chamber from the suction port of the inlet flange 6 of front end-cover 5, and enters in the wind scooper 3 behind catalyst 8 catalytic combustions that are fixed in the suction chamber, discharges extraneous by outlet pipe 2 again.In whole working procedure, high-temp waste gas does not directly contact rear casing 1, this can effectively prevent rear casing 1 excess Temperature of baffler, make the baffler circumferential component not be subjected to temperatures involved, this can make the compacter of the utility model and the setting of its circumferential component, the build of motor is reduced, and erasure effect strengthens.
Should be noted that at last; above content is only in order to illustrate the technical solution of the utility model; but not to the restriction of the utility model protection domain; the simple modification that those of ordinary skill in the art carries out the technical solution of the utility model or be equal to replacement does not all break away from essence and the scope of technical solutions of the utility model.
