Abstract
The utility model discloses a combined type muffler, in particular to the combined type muffler for eliminating the industrial noise. The utility model is characterized in that the utility model comprises an inner cylinder, the inner cylinder is closed shaped, a small hole is arranged on the cylinder wall, a through hole is arranged at one end of the inner cylinder, and a throttling diffusion tube is arranged inside the through hole. The inner end of the throttling diffusion tube is extended into the inner cylinder, and the outer end is extended outside the inner cylinder. The outside of the inner cylinder is covered with a sound absorbing outer cylinder with a separation distance, one end of the sound absorbing outer cylinder is equipped with a cylinder bottom, the center of the cylinder bottom is equipped with a through hole, the outer extending end of the throttling diffusion tube is passed through the through hole and extended outwards, and the outer extending end of the throttling diffusion tube and the through hole is connected in a fixed shape. The combined type muffler has the advantages that the sound muffling effect is good, and the product cost is low, which is suitable in the place with exhaust noise such as a power generating station or a chemical plant.
Description
Technical field
The utility model relates to a kind of noise-abatement equipment.Be the complex muffler that is used for eliminating man-made noise specifically, be applicable to that there is the occasion of exhaust noise in generating plant, chemical plant etc.
Background technology
As everyone knows, in industries such as generating plant, chemical plant, the noise that process gases produced is all bigger, and this man-made noise can bring harm to people's health.For this reason, just must eliminate this noise.Traditional method is to fix a silencer on the noise emission pipeline.At present, the sound suppressor of use mainly contains three kinds of diffused, resistive and micropore jet formulas.These the three kinds of sound suppressors or the weak effect of eliminating the noise, do not reach environmental requirement, otherwise bulky, weight is too heavy, production cost is higher.
The utility model content
Problem to be solved in the utility model provides a kind of complex muffler.This complex muffler, it is effective to eliminate the noise, and production cost is low.
For addressing the above problem, the utility model is taked following scheme:
Complex muffler characteristics of the present utility model are to contain inner core, and this inner core is an enclosed shape, on its barrel aperture is arranged, and the one end has through hole, and the throttling anemostat is arranged in the through hole; The inner end of throttling anemostat is stretched in the inner core, and stretch out outside inner core its outer end.The inner core outside is with the sound absorption urceolus and the two leaves spacing, at the bottom of one end of sound absorption urceolus has tin, there is through hole at tube center, the end, and the overhanging end of throttling anemostat passes outside in this through hole, and is fixedly between the overhanging end of throttling anemostat and this through hole that shape links together.
Take such scheme, have the following advantages:
Because complex muffler of the present utility model contains inner core, this inner core is an enclosed shape, on its barrel aperture is arranged, and the one end has through hole, and the throttling anemostat is arranged in the through hole.The inner end of throttling anemostat is stretched in the inner core, and stretch out outside inner core its outer end.The inner core outside is with the sound absorption urceolus and the two leaves spacing, at the bottom of one end of sound absorption urceolus has tin, there is through hole at tube center, the end, and the overhanging end of throttling anemostat passes outside in this through hole, and is fixedly between the overhanging end of throttling anemostat and this through hole that shape links together.Conventional muffler is optimized, is adopted inner core, urceolus and three main elements of throttling anemostat just to form complex muffler, not only relatively simple for structure, volume is little, in light weight, and improved the noise elimination effect greatly.
Description of drawings
Accompanying drawing is a complex muffler structural representation of the present utility model.
Embodiment
Complex muffler of the present utility model contains an inner core 3, and this inner core is the enclosed shape cylinder, is processed with aperture on the barrel around it, and these apertures are even layout.One end center of inner core 3 is processed with through hole, is provided with throttling anemostat 4 in the through hole.The inner end of throttling anemostat 4 stretch in the inner core 3 and and inner core 3 around leave spacing between barrel, stretch out outside inner core 3 its outer end.Inner core 3 outsides are with sound absorption urceolus 2 and the two leaves spacing.One end of sound absorption urceolus 2 is uncovered shape, at the bottom of the other end is welded with tin.The center at the tube end is processed with through hole, and the overhanging end of throttling anemostat 4 passes outside in this through hole, and is between the overhanging end of throttling anemostat 4 and this through hole and seals shape and weld together.
For ease of being connected, on the overhanging end of throttling anemostat 4, be welded with flange 7 with the gas exhaust duct that produces noise.
When urceolus 2 opening ends that absorb sound are installed,, on an end of sound absorption urceolus 2, be processed with an osculum 6 up for ease of discharging the water in the sound absorption urceolus 2.And for prevent rainwater enter the sound absorption urceolus 2 in, the sound absorption urceolus 2 opening end be provided with rainhat 1, the diameter of this rainhat greater than the sound absorption urceolus 2 diameter.
Install, fix for convenient complex muffler of the present utility model, on the barrel lateral surface of sound absorption urceolus 2, be welded with key seat 5.
Claims (5)
