Technical field
The utility model relates to a kind of baffler, particularly a kind of baffler of many silencing cavity of excellent noise reduction effect.
Background technique
Along with the development of the technology of motor, the application of motor more and more widely, this requirement for baffler is also more and more higher, under some occasion, needs to use powerful motor, this just requires baffler will have good noise reduction.
Summary of the invention
The utility model provides a kind of baffler of many silencing cavity, has good noise reduction.
In order to solve the problems of the technologies described above, the utility model is taked following technological scheme:
A kind of baffler of many silencing cavity comprises the inner core that urceolus and urceolus are wrapped in.Dividing plate and rear bulkhead before being provided with from right to left in the described inner core are separated into three sections cavitys with the inner core cavity, the left side be first silencing cavity, the right side be second silencing cavity, middle is the 3rd silencing cavity; The right side of described urceolus is provided with suction tude, suction tude is passed the right end cap of urceolus and inner core, preceding dividing plate, rear bulkhead and the first silencing cavity conducting, before be embedded with first breathing pipe that is communicated with first silencing cavity and second silencing cavity between dividing plate and rear bulkhead, preceding dividing plate is embedded with second breathing pipe that is communicated with second silencing cavity and the 3rd silencing cavity, and the 3rd silencing cavity is provided with straight-through extraneous tail pipe.
Described inner core is made up of preceding inner core and back inner core butt joint, inner core and back inner core before being respectively from right to left, and preceding inner core is in the rear bulkhead place with back inner core docking location.
Be filled with the glass fibre of sound-absorbing and heat-blocking action between described urceolus and the inner core.
The barrel of inner core is provided with mesh before described.
Described suction tude is the taper that increases gradually from the suction port to the air outlet, has been provided with the catalyst of cleaning of off-gas effect in the outlet port.
The part tube wall of described tail pipe is provided with mesh, and the periphery of mesh is provided with outer tube.
The utility model can play effective noise reduction effect by a plurality of silencing cavity are set, and set breathing pipe has prolonged air flue, has further played the noise reduction effect.
Description of drawings
Fig. 1 is the cross-sectional structural representation of the utility model;
Fig. 2 removes the structural representation of urceolus and inner core for the utility model.
Number in the figure is depicted as: 1-urceolus, inner core before the 2-inner core, 21-, dividing plate before the inner core behind the 22-, 3-, the 4-rear bulkhead, 5-suction tude, 6-first breathing pipe, 7-second breathing pipe, 8-tail pipe, the 9-catalyst, 10-outer tube, 11-first silencing cavity, 12-second silencing cavity, 13-the 3rd silencing cavity.
Embodiment
For the ease of those skilled in the art's understanding, the utility model will be further described below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, a kind of baffler of many silencing cavity comprises the inner core 2 that urceolus 1 and urceolus 1 are wrapped in.Dividing plate 3 and rear bulkhead 4 before being provided with from right to left in the inner core 2 are separated into three sections cavitys with inner core 2 cavitys, the left side be first silencing cavity 11, the right side be second silencing cavity 12, middle is the 3rd silencing cavity 13; The right side of urceolus 1 is provided with suction tude 5, suction tude 5 is passed right end cap, preceding dividing plate 3, rear bulkhead 4 and 11 conductings of first silencing cavity of urceolus 1 and inner core 2, preceding dividing plate 3 is embedded with first breathing pipe 6 that is communicated with first silencing cavity 11 and second silencing cavity 12 with 4 of rear bulkheads, preceding dividing plate 3 is embedded with second breathing pipe, 7, the three silencing cavity 13 that are communicated with second silencing cavity 12 and the 3rd silencing cavity 13 and is provided with straight-through extraneous tail pipe 8.Inner core 2 is made up of preceding inner core 21 and 22 butt joints of back inner core, inner core 21 and back inner core 22 before being respectively from right to left, and preceding inner core 21 is in rear bulkhead 4 places with back inner core 22 docking locations.Be filled with the glass fibre of sound-absorbing and heat-blocking action between urceolus 1 and the inner core 2.The barrel of preceding inner core 21 is provided with mesh.Suction tude 5 is the taper that increases gradually from the suction port to the air outlet, can reduce the aeration resistance of tail gas, has been provided with the catalyst 9 of cleaning of off-gas effect in the outlet port.The part tube wall of tail pipe 8 is provided with mesh, and the periphery of mesh is provided with outer tube 10.
The tail gas of motor is discharged, enter baffler from suction tude 5, at first enter first silencing cavity 11 after catalyst 9 purifications of tail gas by suction tude 5 outlets, enter second silencing cavity 12 by first breathing pipe 6 again, then enter into the 3rd silencing cavity 13 by second breathing pipe 7, then arrive in the outer tube 10 by tail pipe 8, discharged by tail pipe 8 at last.Tail gas has effectively played the noise reduction effect by a plurality of silencing cavity.
