Description
Technical field
The utility model relates to the automobile-used reflux of a kind of engineering machinery and to liquidate anti-formula muffler.
Background technique
At present, along with people are to the understanding of engineering machine vehicle noise hazard, management for Noise measarement is all the more strict, and Engine Exhausting Noise is the main noise source of automobile simultaneously, so adopts exhaust silencer rational in infrastructure to be reduce the most effective method of engineering machinery pass-by noise.Current existing acoustic wave filter structure generally comprises suction tude, housing, outlet pipe etc.And its silencing apparatus is expanssion type reactive muffler or impedance composite muffler substantially.With regard to its principle, existing silencing apparatus mainly considers structure and the Placement of silencing apparatus expansion chamber, and the selection of sound-absorbing material, and what but have ignored air-flow flows to problem.
Summary of the invention
The purpose of this utility model is to overcome the deficiency existed in above-mentioned technology, provides a kind of compact structure, reasonable in design, and the reflux effectively can cutting down exhaust sound in the whole speed range of motor liquidates anti-formula muffler.
In order to achieve the above object, the technical solution adopted in the utility model is: comprise noise elimination cylindrical shell, the two ends of noise elimination cylindrical shell are provided with right end cap, left end cap, in noise elimination cylindrical shell, front dividing plate is installed, noise elimination inner barrel is divided into three chambers by rear bulkhead, first chamber, second chamber, 3rd chamber, front dividing plate outer rim is connected with noise elimination cylinder inboard wall, front dividing plate has two installation of core pipe holes, rear bulkhead outer rim is connected with noise elimination cylinder inboard wall, rear bulkhead has two installation of core pipe holes, first core pipe is through front dividing plate, two-port respectively with the first chamber, second chamber communicates, second core pipe is through rear bulkhead, two-port respectively with the second chamber, 3rd chamber communicates, 3rd core pipe is simultaneously through front dividing plate and rear bulkhead, two-port respectively with the first chamber, 3rd chamber communicates, suction tude is passed noise elimination cylindrical shell lower ending opening and is communicated with the first chamber, outlet pipe passes noise elimination cylindrical shell upper end open and communicates with the second chamber.
The utility model has the advantages that:
The utility model compact structure, reasonable in design, effectively can cut down engine firing frequencies, not only reduce cost, improve efficiency, because reflux liquidates regulating action, make the back pressure of motor under each rotating speed lower, thus ensure that power character and the Economy of motor.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model silencing pot cross-sectional structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
From Fig. 1-Fig. 2, the utility model comprises noise elimination cylindrical shell 1, the two ends of noise elimination cylindrical shell 1 are provided with right end cap 16, left end cap 9, front dividing plate 12 is installed in noise elimination cylindrical shell 1, noise elimination cylindrical shell 1 inside is divided into three chambers by rear bulkhead 10, first chamber 17, second chamber 18, 3rd chamber 19, front dividing plate 12 outer rim is connected with noise elimination cylindrical shell 1 inwall, front dividing plate 12 has two installation of core pipe holes 3, 13, rear bulkhead 10 outer rim is connected with noise elimination cylindrical shell 1 inwall, rear bulkhead 10 has two installation of core pipe holes 6, 8, first core pipe 2 is through front dividing plate 12, two-port communicates with the first chamber 18, chamber 17 second respectively, second core pipe 7 is through rear bulkhead 10, two-port respectively with the second chamber 18, 3rd chamber 19 communicates, 3rd core pipe 11 is simultaneously through front dividing plate 12 and rear bulkhead 10, two-port respectively with the first chamber 17, 3rd chamber 19 communicates, suction tude 14 is passed noise elimination cylindrical shell 1 lower ending opening 15 and communicates with the first chamber 17, outlet pipe 5 passes noise elimination cylindrical shell 1 upper end open 4 and communicates with the second chamber 18.
Core-pipe subassembly described in the utility model, in silencing apparatus, charge air flow is divided into two-way, one route core pipe A drains into steam outlet pipe, another route core pipe C discharges and turns back to air outlet by core pipe B reflux again, two-way air-flow forms reverse convection current in outlet pipe import, because reflux liquidates the regulating action of anti-formula, make motor back pressure under each rotating speed lower, thus ensure that power character and the Economy of motor.
