Abstract
The utility model provides a muffler, which effectively increases the contact area of gas and a silencing barrel on the premise of ensuring normal removal of gas flow and can better improve the silencing effect.
Description
Technical Field
The utility model relates to the technical field of noise reduction equipment, in particular to a muffler.
Background
The noise reduction equipment plays very important effect to the treatment environmental pollution, and ordinary muffler generally includes muffler section of thick bamboo and shell, and gaseous after getting into from the muffler inner tube, through the inside amortization processing of muffler, reduces and disappear sound to reach the amortization effect, the area of contact of gaseous and the muffler section of thick bamboo is less relatively in the current muffler, and its amortization effect is relatively poor.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model provides the silencer, which effectively increases the contact area of gas and the silencing barrel and can better improve the silencing effect on the premise of ensuring the normal elimination of air flow.
The technical scheme is as follows: the utility model provides a silencer, its includes the muffler shell, muffler shell endotheca is equipped with muffler section of thick bamboo and sound absorption screen barrel, its characterized in that: the silencer is characterized in that an air inlet is formed in the silencer cylinder, an air outlet is formed in the sound absorption screen cylinder, the sound absorption screen cylinder comprises a first supporting plate and a second supporting plate, a plurality of through holes are correspondingly formed in the first supporting plate and the second supporting plate, and a first perforated plate cylinder section is correspondingly arranged between the through holes.
It is further characterized by: the muffler barrel comprises a muffler inner barrel; the silencer inner cylinder is provided with a first flange, the air inlet is arranged on the first flange, the silencer shell is connected with the sealing head, the sealing head is provided with a second flange, one end of the sound absorption screen cylinder is connected with the sealing head, and the air outlet is arranged on the second flange; the first supporting plate is connected with a second perforated plate cylinder section, and the second perforated plate cylinder section is connected with the silencer inner cylinder through a sealing plate; the silencer inner cylinder is provided with a plurality of silencer cylinder through holes which are symmetrically arranged in a triangular shape.
According to the scheme, the air inlet is formed in the silencer cylinder, the air outlet is formed in the sound absorption screen cylinder body, the sound absorption screen cylinder body comprises the first support plate and the second support plate, the plurality of through holes are correspondingly formed in the first support plate and the second support plate, the first perforated plate cylinder section is arranged between the corresponding through holes, and when air flows, the flowing direction of air is effectively changed, so that the flowing time is prolonged, sound absorption is better achieved, and the silencing effect can be effectively improved.
Drawings
FIG. 1 is a schematic view of a muffler according to the present utility model;
FIG. 2 is a left side view of FIG. 1;
fig. 3 is a schematic view of a first support plate and a second support plate.
Detailed Description
See fig. 1, fig. 2, fig. 3, a muffler, it includes muffler shell 1, muffler shell 1 endotheca is equipped with muffler section of thick bamboo 2 and sound absorption screen barrel 3, be provided with air inlet 4 on the muffler section of thick bamboo 2, be provided with gas outlet 5 on the sound absorption screen barrel 3, sound absorption screen barrel 3 includes first backup pad 6 and second backup pad 7, be provided with a plurality of through-holes 8 on corresponding in first backup pad 6 and the second backup pad 7, set up first perforated plate shell section 9 between the through-hole that corresponds, form the sound absorption screen barrel that many perforated plate shell sections are constituteed, when the air current flows, effectively changed the flow direction of gas, make flow time lengthen, realize the absorption of sound betterly, can improve the amortization effect effectively.
The perforated plate cylinder section is a silencing cylinder and also plays a silencing role.
The muffler cylinder 2 comprises a muffler inner cylinder 10, a plurality of muffler cylinder through holes 11 are formed in the muffler inner cylinder 10, the muffler cylinder through holes 11 are symmetrically arranged in a triangular shape, and the through holes are staggered in a triangular shape, so that the gas movement track is lengthened, and the silencing effect is guaranteed.
Be provided with first flange 12 on the muffler inner tube 10, air inlet 4 sets up on first flange 12, and muffler shell 1 connects head 16, is provided with second flange 13 on the head 16, and head 16 is connected to sound absorption screen barrel 3 one end, and air outlet 5 sets up on second flange 13, realizes that the muffler is easy to assemble.
The first backup pad 6 is connected the perforated plate shell section 14 of second, and the perforated plate shell section of second 14 passes through shrouding 15 and connects muffler inner tube 10 for the air current has realized many times sound absorption in the muffler section of thick bamboo, has effectively improved the amortization effect of muffler.
The present utility model and its embodiments have been described above by way of illustration and not limitation, and the embodiments of the present utility model shown in the drawings are not limited thereto, and the actual structures are not intended to be within the scope of the present utility model unless they depart from the spirit of the utility model.
