Abstract
The utility model discloses a muffler which is used for minimizing noise generated when air is returned in a cylinder. The muffler comprises a noise reduction box and a noise reduction medium. The noise reduction box is an enclosed space. The noise reduction box is equipped with an air inlet and an air outlet. The air inlet is connected to an air return port of a solenoid valve of a cylinder. The air inlet is provided with a silencer. The noise reduction medium is arranged inside the noise reduction box and fully covers the air inlet and the air outlet. The muffler is simple in structure, low in economic cost and fine in noise reduction effect.
Description
Technical field
The utility model relates to a kind of baffler.
Background technique
The patent of CN201020173898 discloses a kind of circulating conveyor; Said feedway provides driving force through cylinder in the process that moves ahead; Cylinder will constantly be inflated return-air in flexible; When return-air, often produce very big noise, workman's production environment has been caused noise pollution.
The model utility content
For addressing the above problem, the utility model provide a kind of simple in structure, financial cost is low and the baffler of good muffling effect.
1. for realizing above-mentioned purpose, the utility model provides following technological scheme: a kind of baffler, and the noise that is produced when being used to reduce the cylinder return-air comprises sound-muffling box and noise reduction medium, said sound-muffling box is an airtight space; Said sound-muffling box also offers suction port and air outlet; Said suction port is connected in the return-air mouth of said cylinder solenoid valve; Said suction port place also is connected with silencing apparatus; Said noise reduction medium is located in the said sound-muffling box and is covered said suction port and air outlet fully.
Preferably, said suction port and air outlet are the porous gas port.
Preferably, said silencing apparatus is powder sintered silencing apparatus.
Preferably, said noise reduction medium is that noise reduction is cotton.
Preferably, said sound-muffling box is cube shaped sound-muffling box.
Preferably, said sound-muffling box is cylindrical sound-muffling box.
Adopt the beneficial effect of above technological scheme to be: the combination through simple sound-muffling box and noise reduction medium, reach good erasure effect, and the financial cost of sound-muffling box and noise reduction cotton is low, has saved cost of production.

Wherein, cotton B 3. powder sintered silencing apparatus 41. cylinder solenoid valves 42. tracheaes of 11. cube shaped sound-muffling box 12. suction port A cotton A 22. noise reductions of 13. air outlet A, 14. cylindrical sound-muffling box 15. suction port B 16. air outlet B 21. noise reductions.
Embodiment
Specify the preferred implementation of the utility model below in conjunction with accompanying drawing.
Embodiment 1
Referring to Fig. 1; Shown in embodiment wherein: a kind of baffler; The noise that is produced when being used to reduce the cylinder return-air; Comprise a cube shaped sound-muffling box 11 and the cotton A21 of noise reduction, said cube shaped sound-muffling box 11 is an airtight space, and said cube shaped sound-muffling box 11 offers three suction port A12 and three air outlet A13; Said suction port A12 is connected in the return-air mouth of said cylinder solenoid valve 41; Said suction port A12 place also is connected with three powder sintered silencing apparatuss 3; The cotton A21 of said noise reduction is located in the said cube shaped sound-muffling box 11 and covers said suction port A12 and air outlet A13 fully.
When cylinder moving arrives needed position, need return-air, open cylinder solenoid valve 41; Gas in the cylinder passes through said cylinder solenoid valve 41 and tracheae 42, through said suction port A12, and powder sintered silencing apparatus 3; The decibel of sound is lowered to 80% of original sound, passes through the cotton A21 of said noise reduction again, and sound is lowered to 20% of original sound; After said air outlet A13 has realized air ventilation.
Embodiment 2
Referring to Fig. 2; Shown in legend wherein: a kind of baffler; The noise that is produced when being used to reduce the cylinder return-air; Comprise a cylindrical sound-muffling box 14 and the cotton B22 of noise reduction, said cylindrical sound-muffling box 14 is an airtight space, and said cylindrical sound-muffling box 14 offers five suction port B15 and five air outlet B16; Said suction port B15 is connected in the return-air mouth of said cylinder solenoid valve 41; Said suction port B15 place also is connected with five powder sintered silencing apparatuss 4; The cotton B22 of said noise reduction is located in the said cylindrical sound-muffling box 14 and covers said suction port B15 and air outlet B16 fully.
When cylinder moving arrives needed position, need return-air, open cylinder solenoid valve 41; Gas in the cylinder passes through said cylinder solenoid valve 41 and tracheae 42, through said suction port B15, and powder sintered silencing apparatus 3; The decibel of sound is lowered to 80% of original sound, passes through the cotton B22 of said noise reduction again, and sound is lowered to 20% of original sound; After said air outlet B16 has realized air ventilation.
All the other are identical with said embodiment 1, and difference is that said cube shaped sound-muffling box offers five suction ports and five air outlets.
Embodiment 4
All the other are identical with said embodiment 2, and difference is that said cylindrical sound-muffling box offers three suction ports and three air outlets.
Adopt the beneficial effect of above technological scheme to be: the combination through simple sound-muffling box and noise reduction medium, reach good erasure effect, and the financial cost of sound-muffling box and noise reduction cotton is low, has saved cost of production.
Above-described only is the preferred implementation of the utility model; Should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; Can also make some distortion and improvement, these all belong to the protection domain of the utility model.
