The purpose of the utility model provides a kind of easy-to-dismount silencing apparatus.
For achieving the above object; The present invention provides a kind of silencing apparatus, and it comprises connecting cover, the bottom disc that offers inlet hole, removably is connected with the cylindrical shell of a plurality of rings between connecting cover and the bottom disc; The radius of a plurality of cylindrical shells increases successively; And a plurality of cylindrical shells are enclosed within outside another according to one of the order that radius increases, and constitute a plurality of expansion chambers in the inner chamber and the space between adjacent two cylindrical shells of the most inboard cylindrical shell, and adjacent expansion chamber is connected through the pore that is opened on the cylindrical shell; The outermost expansion chamber is communicated to the external world through exhaust port; Exhaust port is opened on the sidewall of outermost surface cylindrical shell, or is opened on the part corresponding with the outermost expansion chamber of bottom disc or connecting cover, on connecting cover, has one and is used for the joint that removably connects mutually with application apparatus.
Further, the joint on the connecting cover is a screwed connecting rod or a flange.
Further, connecting cover with the cylindrical shell facing surfaces on be recessed to form the connecting cover clip slots that a plurality of and edge shape each cylindrical shell match, the tip portion of each cylindrical shell is inserted in the connecting cover clip slot accordingly.
Further, the bottom disc with the cylindrical shell facing surfaces on be recessed to form the bottom disc clip slots that a plurality of and edge shape each cylindrical shell match, insert in the disc clip slot of bottom accordingly the bottom of each cylindrical shell.
Preferably, the coaxial distribution of a plurality of cylindrical shells.
Preferably, perforate respectively on bottom disc and the connecting cover, a screw rod passes these Kong Houyu one nuts cooperations and connecting cover, cylindrical shell, bottom disc is coupled together.
The utility model compared with prior art has advantage: through dismountable mode silencing apparatus is connected to application apparatus; And adopt disassembled mode to assemble formation the silencing apparatus; Make silencing apparatus to remove and carry out the inside cleaning; And just owing to can in time cleaning, so this silencing apparatus can be applied on the capsule device for disassembling.
Description of drawings
Accompanying drawing 1 is the utility model embodiment's a sectional view;
Accompanying drawing 2 is the sectional view of A-A direction among Fig. 1;
Wherein: 11, bottom disc; 112, bottom disc clip slot; 120, exhaust port; 20, cylindrical shell; 201, expansion chamber; 202, pore; 30, screw rod; 40, connecting cover; 402, outside thread connecting rod; 4021, inlet hole; 403, connecting cover clip slot; 50, nut.
Embodiment
Embodiment shown in Fig. 1-2; This silencing apparatus comprises the cylindrical shell 20 of connecting cover 40, bottom disc 11, a plurality of rings between connecting cover 40 and bottom disc 11; Have one on the connecting cover 40 and be used for the outside thread connecting rod 402 that removably connects mutually with application apparatus, outside thread connecting rod 402 is a hollow structure, wherein has an inlet hole 4021; Have outside thread on the outside thread connecting rod 402, be used for linking to each other with easily detachable mode with application apparatus.Certainly, also can adopt alternate manner to make connecting cover 40 be connected to application apparatus removably, 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.
Shown in Fig. 1-2, as can be seen from the figure, a plurality of cylindrical shells 20 adopt the direction of horizontal ring set to arrange in the present embodiment.The radius of the cylindrical shell 20 of a plurality of rings increases successively, and a plurality of cylindrical shell 20 is enclosed within outside another according to one of the order that radius increases, and constitutes a plurality of expansion chambers 201 at the inner chamber of the most inboard cylindrical shell and the space between adjacent two cylindrical shells.The gas that inlet hole 4021 is discharged application apparatus directly imports the inner chamber of the most inboard cylindrical shell 20, in the just the most inboard expansion chamber 201.Offer a plurality of pores 202 on the wall of each cylindrical shell 20; Be used to be communicated with adjacent two expansion chambers 201 and finally be communicated to the external world through exhaust port 120; Exhaust port 120 is opened on the sidewall of outermost surface cylindrical shell 20, or on the part corresponding with outermost expansion chamber 201 that is opened in bottom disc 11 or connecting cover 40.Pore 202 is preferably with certain punching rate, be arranged on the whole wall of cylindrical shell with distribution mode rule or at random.Noise gas dwindles with more than 202 amplification of pore through each expansion chamber 201, in this process, realizes the noise elimination purpose.
Connecting cover 40 with cylindrical shell 20 facing surfaces on be recessed to form the connecting cover clip slots 403 that a plurality of and edge shape each cylindrical shell match, the tip portion of each cylindrical shell is inserted in each connecting cover clip slot 403 accordingly.
Bottom disc 11 with the cylindrical shell facing surfaces on be recessed to form the bottom disc clip slots 112 that a plurality of and edge shape each cylindrical shell match, insert in each bottom disc clip slot 112 accordingly the bottom of each cylindrical shell.
For the edge shape with cylindrical shell coincide; A plurality of connecting cover clip slots 403 are ring respectively with a plurality of bottoms disc clip slot 112 and one of order increasing by radius is enclosed within outside another; In the present embodiment; Connecting cover clip slot, bottom disc clip slot all are the grooves of ring, in order to the corresponding edge of each cylindrical shell is all accommodated into.Can certainly be other mode, for example, clip slot be curved; Accordingly, the edge of cylindrical shell has part outstanding, and outstanding part is coincide with the shape of clip slot; Perhaps, so-called clip slot is several breach, and there are several projections the end of cylindrical shell; Be connected with the embedded cooperation of breach through projection, these modes are all grasped by those skilled in the art, therefore do not adopt accompanying drawing further to give unnecessary details.
In the present embodiment, a plurality of cylindrical shell 20 is preferred according to the such coaxial distribution shown in Fig. 1-2.
In the present embodiment, perforate respectively on bottom disc 11 and the connecting cover 40, two screw rods 30 pass these Kong Houyu nuts 50 and cooperate and connecting cover 40 and bottom disc 11 are coupled together, and a plurality of cylindrical shells are clipped in therebetween.Certainly, also can use screw thread or other quick Placement that connecting cover, each cylindrical shell and bottom disc are connected into integral body, these modes are all grasped by those skilled in the art, therefore do not adopt accompanying drawing further to give unnecessary details.
