Abstract
The invention relates to a novel labyrinth suction muffler, which comprises an air suction pipe, an air outlet pipe and a shell, wherein a plurality of annular baffles (1) are arranged on a concave front shell; a concave back shell cover corresponding to the concave front shell is provided with a plurality of annular baffles (2); a labyrinth silencing channel is formed at an overlapping position of each annular baffle (1) on the concave front shell and each annular baffle (2), corresponding to each annular baffle (1), on the concave back shell cover; expansion chambers consist of the annular baffles (1), the annular baffles (2) corresponding to the annular baffles (1) and the shell; the air suction pipe is communicated with the air outlet pipe through the silencing channels and the expansion chambers; a convex edge of the concave front shell is embedded in a groove of the concave back shell cover and fixes the concave front shell and the concave back shell cover through a fastener; and the height of the annular baffles is smaller than that of the shell consisting of a concave back shell and the concave front shell. The improved structure have good silencing effect, and can reduce noise pollution and meet requirement of environmental protection.
Description
One. technical field
The present invention relates to a kind of silencing apparatus, particularly a kind of inhaling silencer.
Two. prior art
The silencing apparatus that uses on the present silencing apparatus, particularly air compressor that uses, though can play the effect of noise elimination, the noise elimination effect is bad, when causing equipment to use, the noise of equipment is still very big, can not satisfy environmental protection and user's requirement, can not eliminate noise pollution.
Three. technology contents
The objective of the invention is: design a kind of novel silencing apparatus, it is effective to reach noise elimination, reduces noise pollution, satisfies user and environmental protection requirement.
The present invention adopts following structure to realize above-mentioned purpose: a kind of novel labyrinth suction muffler, comprise sucking pipe, steam outlet pipe, housing, on the spill front case, be provided with a plurality of toroidal membranes (1), also be provided with a plurality of toroidal membranes (2) at spill rear shell cover and spill front case corresponding section, each toroidal membrane (2) on the corresponding with it spill rear shell cover of each toroidal membrane (1) on the spill front case should some be overlapping, the bedded position forms noise elimination road, mystery palace, form expansion chamber with housing between the toroidal membrane (1) and between the corresponding with it toroidal membrane (2), or toroidal membrane (1) and corresponding with it toroidal membrane (2) and housing composition expansion chamber, sucking pipe communicates with steam outlet pipe by noise elimination road and expansion chamber, convex edge on the spill front case is embedded in the groove of spill rear shell cover, and by fastening piece spill front case and spill rear shell cover are fixed the housing height that the height of toroidal membrane is formed less than spill rear case and spill front case.
On the spill front case, be provided with three toroidal membranes (1), also be provided with three toroidal membranes (2) at spill rear shell cover and spill front case corresponding section.
In expansion chamber, be provided with acoustical cotton or filter, in through the expansion chamber behind the noise elimination road, the first mystery palace, be provided with filter, be provided with acoustical cotton in all the other expansion chamber.
Said structure after the improvement, it is effective to reach noise elimination, reduces noise pollution, satisfies environmental protection requirement.And this is simple in structure, design ingenious, to eliminate noise effects good not increasing under the condition of cost, particularly can play good governance role for noise pollution, along with growth in the living standard, current society, the environmental protection of people's pay attention to day by day, people thirst for quietly working under the environment, and the pollution that brings for noise more and more causes people's attention, the big shortcoming of noise when the present invention is directed to the air compressor use, existing silencing apparatus is improved, this big shortcoming of noise when well having overcome the air compressor use, people can quietly use air compressor under the environment, to create good working environment.

Five. embodiment
Labyrinth suction muffler, as Fig. 1, Fig. 2 and shown in Figure 3, comprise sucking pipe (3), steam outlet pipe (5), housing (4), housing (4) is made up of spill rear shell cover (42) and spill front case (41), on spill front case (41), be provided with three toroidal membranes (1), also be provided with three toroidal membranes (2) in spill rear shell cover (42) and spill front case (41) corresponding section, each toroidal membrane (2) bedded position on each toroidal membrane (1) on the spill front case (41) and the corresponding with it spill rear shell cover (42) forms noise elimination road, mystery palace 7 as shown in Figure 2, the corresponding with it toroidal membrane of toroidal membrane (1) (2) is formed expansion chamber (8) with housing (4), sucking pipe (3) is on spill front case (41), sucking pipe (3) communicates with steam outlet pipe (5) by noise elimination road (7) and expansion chamber (8), convex edge (9) on the spill front case (41) is embedded in the groove (10) of spill rear shell cover (42), and it is spill front case (41) and spill rear shell cover (42) is fixing by fastening piece (11), the height of toroidal membrane (1) or (2) is less than the housing height of spill rear shell cover and spill front case composition, and the height of housing is the distance between spill rear shell cover (42) and the spill front case (41).
In expansion chamber, be provided with acoustical cotton (13) or filter (12).
As Fig. 4 and shown in Figure 2, be provided with annular filter (12) in the expansion chamber after sucking pipe (3) is through noise elimination road, the first mystery palace (71), thereby playing the contaminant filter that will flow in the gas falls, the working life of prolongation equipment, in all the other expansion chamber, be provided with acoustical cotton (13), better reduce noise.
Fig. 4 is a fundamental diagram of the present invention, also move towards flow chart for gas, wherein arrow (6) is the trend of air-flow, first expansion chamber (81) and the 4th expansion chamber (84) are that toroidal membrane (1) and corresponding with it toroidal membrane (2) are formed with housing (4), second expansion chamber (82) and the 3rd expansion chamber (83) are to form with housing (4) between the toroidal membrane (1) and between the corresponding with it toroidal membrane (2), noise gas flows out from steam outlet pipe (5) after sucking pipe (3) is come in along the trend of air-flow, at first noise gas is after sucking pipe (3) enters first expansion chamber 81, enter second expansion chamber (82) through the first noise elimination road (71), enter the 3rd expansion chamber (83) through the second noise elimination road (72) again, enter the 4th expansion chamber (84) through the 3rd noise elimination road (73), the 4th expansion chamber (84) communicates with steam outlet pipe (5), the gas of coming in from sucking pipe (3) reduces from its noise of steam outlet pipe (5) effluent air more greatly through after this structure.
Only be one embodiment of the present of invention shown in the accompanying drawing, toroidal membrane can be provided with as required, forms a plurality of noise eliminations road and a plurality of expansion chamber thus, and the placement of filter and acoustical cotton also can be placed as required, and object lesson exemplifies no longer one by one, all in protection.
