Abstract
The utility model provides a spiral silencer, which is a silencing chamber composed of an external casing with a circular cylinder-shaped or conical body and a micro hole cylinder; the internal part of the silencing chamber is divided into a plurality of small chambers by a separation baffle ring with small holes; or the internal part of the silencing chamber is filled with glass cotton or other high-temperature resistant silencing materials; the internal part of the micro hole cylinder is a spiral body, and the end is fixed with a circular disk with the holes. The spiral silencer can be installed and used on exhaust openings of all kinds of motor vehicles or machine devices for silencing; influence on power is small, and silencing effects are very good.
Description
The utility model is a kind of spiral silencer, belongs to the noise elimination technique field.
The silencing apparatus that is used for the outlet pipe of various Motor Vehicle or other power equipment at present for power in various degree considerable influence is arranged all, and the noise elimination effect is not ideal.
It is a kind of little to power influences that the purpose of this utility model will provide exactly, the spiral silencer of noise elimination better effects if.
Spiral silencer of the present utility model, mainly contain frame (1), micropore tube (2), separate baffle ring (3), spiral page or leaf (4), screw stud (5), wherein spiral page or leaf (4) is positioned at micropore tube (2) with the heliconid of screw stud (5) composition, the front of spiral page or leaf (4) is smooth surface or non-light face, the separation baffle ring (3) that has micropore is fixed on the outer surface of micropore tube (2) with certain spacing, be separated in the cavity between frame (1) and micropore tube (2) and be no less than three little anechoic room, perhaps insert glass wool or other high temperature resistant muffler material in the cavity anechoic room between frame (1) and micropore tube (2), can reserve one section empty stool control mode at the anechoic room end and discharge in air-flow.The afterbody of shell inner surface is fixed with disk (8), and disk (8) is gone up the position corresponding with anechoic room aperture.
Working principle of the present utility model is: air-flow enters in the silencing apparatus from suction port (7), act on the front of spiral page or leaf (4), the spiral page or leaf (4) of flowing through rotation forward, the energy of decay air-flow, the air-flow Pulse wave enters decay in the anechoic room by micropore tube (2), rotation reduces the air-flow after the force and velocity of a current, after micropore tube (2), anechoic room, disk (8) are eliminated the noise step by step, flows to relief opening (6) and discharges.
Adopt spiral silencer of the present utility model, its advantage is little for power influences, can improve the noise elimination effect preferably, and is applicable to the noise elimination at various outlet pipes road junction.
Fig. 1 is a sectional structure schematic representation of the present utility model, and wherein heliconid is not to cut open expression.
Fig. 2 is two kinds of surface structure schematic representation of the present utility model, and its internal structure is similar.
Embodiment of the present utility model is as follows: spiral page or leaf (4) is enclosed within on the screw stud (5) by central hole location, and can weld fixing, disk (8) is fixing in the tail end welding of central position and screw stud (5), micropore tube (2) is enclosed within spirochetal outside, terminal and disk (8) joins, and separation baffle ring (3) is enclosed within the outside of micropore tube (2) with certain spacing and can fixes; Perhaps insert sound-absorbing material in the anechoic room between frame (1) and micropore tube (2), frame (1) is enclosed within outside the anechoic room, with suction port (7) and relief opening (6) welding.According to the above, just can form spiral silencer of the present utility model.
Claims (3)
1, a kind of spiral silencer, by frame (1), micropore tube (2), separate baffle ring (3), spiral page or leaf (4), screw stud (5), disk (8) is formed, it is characterized in that one mainly forms anechoic room by cylinder or conical frame (1) with micropore tube (2), interior being separated into by the separation baffle ring (3) that has aperture that is fixed in micropore tube (2) outer surface of anechoic room is no less than three little anechoic room, perhaps insert glass wool or other resistant to elevated temperatures muffler material between frame (1) and micropore tube (2), the heliconid of being made up of spiral page or leaf (4) and screw stud (5) is positioned at micropore tube (2).The heliconid back is to be fixed on frame (1) internal surface, the disk (8) that diameter is identical with frame (1) internal diameter, and aperture is left at position corresponding with anechoic room on the disk.
2, spiral silencer according to claim 1, it is characterized in that frame adopt welding fabrication or be shaped to two sections after from the runic position with rivet or screw secure engagement.
3, spiral silencer according to claim 1 is characterized in that spiral page or leaf (4) front is smooth surface or non-light face.
