Embodiment

Describe in detail below in conjunction with the preferred embodiment of accompanying drawing to the utility model.

Shown in Fig. 1-4; This silencing apparatus comprises connecting cover 40, bottom disc 11, removably is connected in the cylindrical shell of the ring between connecting cover 40 and the bottom disc 11; In illustrated embodiment, cylindrical shell is made up of with the clip 90 of banding in sealing gasket 80 outsides the sealing gasket 80 of ring.

One hollow newel 60 is set between connecting cover 40 and the bottom disc 11, and newel 60 is in the cylinder lumen, between the inwall newel of the outer wall of newel 60 and sealing gasket 80, constitutes noise elimination cavity.Newel 60 is hollow, and the one of which end opens and an inlet hole 61 is provided, and the other end is closed, on the sidewall of newel 60, offers a plurality of through holes 601.Have perforation 401 on the connecting cover 40, an end of offering inlet hole 61 of newel 60 reaches the outside by perforation 401, and has one section outside thread 603 on this end that is positioned at the outside of newel 60; Be used for linking to each other with easily detachable mode, certainly, also can adopt alternate manner to make connecting cover 40 be connected to application apparatus removably with application apparatus; Such as a flange is set on connecting cover; Be connected with application apparatus through flange, this also is common Placement, does not give unnecessary details at this.

Be provided with a plurality of spacers not with

holes

72 and 71 spacers with holes that are radial extension from newel 60 in the noise elimination cavity; Offer a plurality of pores 711 on the spacer with holes; Spacer 72 not with holes preferably is spaced with the mode of rule with spacer 71 with holes; Can be with reference to that kind shown in Figure 3, two spacers 71 with holes and a spacer 72 not with holes are arranged alternately.Spacer 72 not with holes is separated into many group expansion chambers 200 with noise elimination cavity; Every group of expansion chamber 200 comprises a plurality of expansion chambers; These expansion chambers separate through spacer 71 with holes; First expansion chamber in every group of expansion chamber 200 directly is connected with the through hole 601 on the newel 60; Offer a plurality of exhaust ports 110 in the zone of the bottom disc 11 that last expansion chamber in every group of expansion chamber 200 is corresponding, be communicated with through the pore 711 on the spacer 71 with holes between a plurality of expansion chambers in every group of expansion chamber 200.Reaching other position of this paper mentioned " first " and " last " here is the always definition of walking according to air-flow, and the expansion chamber that air-flow arrives at first is first expansion chamber, and the expansion chamber of the last process of air-flow is last expansion chamber.

A plurality of spacers not with holes 72 and spacer 71 with holes are preferably with the noise elimination cavity five equilibrium; The size of each expansion chamber equates; Expansion chamber number in every group of expansion chamber 200 also equates; Correspondingly, the through hole 601 on the newel 60 is also just evenly arranged along the circumferencial direction of newel 60, on average gets into the effect of respectively organizing expansion chamber 200 to reach air-flow.

Connecting cover 40 with the noise elimination cavity facing surfaces on offer a plurality of first slots 404; Bottom disc 11 with the noise elimination cavity facing surfaces on offer a plurality of second slots 113 corresponding to first slot 404, the top of a plurality of spacers not with holes 72 and spacer 71 with holes and bottom are inserted in respectively respectively in first slot 404 and second slot 113 accordingly.Make adjacent expansion chamber and adjacent airtight completely cutting off of expansion chamber group through first slot 404 and second slot 113; Air-flow is concentrated to be passed through from pore; Let air-flow better accomplish amplification, the process of dwindling strengthens the noise elimination effect; And spacer is positioned, be shifted in noise elimination cavity to avoid spacer.

Further; Preferably also offer a plurality of the 3rd slots 602 on the outer side wall of newel 60 accordingly; The 3rd slot 602 extends corresponding to the position of first and second slots along the direction that is parallel to newel 60 axis to be offered, and a side that joins with newel 60 of each spacer 72 not with holes and spacer 71 with holes is inserted in each the 3rd slot 602 accordingly.

In the preceding text and below " top " and " bottom " mentioned be that custom according to the technician defines, so-called " top ", promptly with the hithermost end of application apparatus, what is called " bottom " is promptly away from that end of application apparatus.

In order to locate the cylindrical shell of forming by sealing gasket 80 and clip 90 well; First boss 402 of the circle that can be on connecting cover 40 convexes to form apart from the position on the surface of its edge one segment distance; Likewise; On bottom disc 11, form second boss 112, the two ends of cylindrical shell are enclosed within respectively on first boss 402 and second boss 112.

In addition, also connect fixing between connecting cover 40 and the bottom disc 11 through component such as connecting rod 30 and nuts 50.

The diameter of each pore 711, through hole 601 and the exhaust port 110 all width than each expansion chamber is much little, and this does not do specific definition and introduction for the essential structure that silencing apparatus needs at this.

The gas of discharge gets in the inner chamber of newels 60 through inlet hole 61---for example capsule device for disassembling---from application apparatus; Get into through the through hole on the newel 60 601 then and respectively organize on the expansion chamber 200, in each group expansion chamber 200, pass through each pore 711 and each expansion chamber successively after; Finally discharge from exhaust port 110; In this process, the sound of air-flow is weakened, and reaches the noise elimination effect with this.

As stated, we are illustrated according to the aim of the utility model fully, but the utility model is not limited to the foregoing description and implementation methods.The practitioner of correlative technology field can carry out different variations and enforcement in the scope that the technological thought of the utility model is permitted.
