Description

Baffler
The present invention relates to the baffler of compressor air suction mouth, it has a plurality of annular noise reduction parts, and curved guide parts all can be synthesized in the interior edge of each parts.
This type of baffler is known, is used to eliminate the sound wave that produces during the compressor operation of devices such as exhaust turbine supercharger or gas turbine.For this purpose, they have many noise reduction parts baffler inner space that is arranged in spaced a certain distance.The noise reduction parts generally are made up of a support member and a noise reduction part of being made by quieter material.
The filter of inhaled air through being installed on the baffler periphery flows into the baffler inner space, enters compressor through the noise reduction part again, produces the sound wave opposite with airflow direction by compressor, thereby pressure maximum and pressure minimum occur.Under the situation of pressure maximum, the air stream warp also is forced in the quieter material, and under the situation of pressure minimum, air sucking-off from these materials again, thus erasure effect guaranteed.So the noise reduction part plays the buffer effect, has compensated the pressure difference between pressure maximum and the pressure minimum to a certain extent, thereby has reduced the amplitude of sound wave.
A kind of discoidal noise reduction parts have been described among the patent specification CH593426, it by a support member, be installed in the noise reduction part of support member both sides and form by the fixing grid part of rivet.The noise reduction part is clipped between the grid part, and support member has a continuous core, and recessed gradually on both sides.Disc noise reduction parts interior along can synthetic curved guide parts (also shown in patent specification CH594139), thus the air flow deflector that radially enters is flowed to predetermined outlet, avoided the loss that causes because of eddy current with this.
The noise reduction parts of being made up of the many fritters that are arranged on the peripheral direction also are known.These noise reduction parts support with a root system bar, are fixed together by means of distance bushing, and are fixed in the silencer casing.
All there are some shortcomings in these designs.Vibrating under the very strong situation, finding that above-mentioned baffler becomes a time-dependent system when being subjected to the higher frequency excitation, thereby can not unrestrictedly use.Because of this class baffler is made up of many single parts, so its assembling requires height.In addition, the noise reduction part also can become flexible and weares and teares owing to compression shock and thermal shock.
The present invention attempts to avoid all these shortcomings.So the objective of the invention is to create a kind of baffler that starts said the sort of type at this paper, even this baffler also forms a stable system under the situation of judder, it is characterized in that cost of production is low for known baffler, and improved the baffler function.In addition, it is also based on another purpose, and promptly the design of baffler makes that not dismantling filter frame just can carry out the filter cleaning easily.
According to the present invention, this realizes with the following method: the main body of baffler is that cast inblock forms; Silencing block adopts the radially casting rib of trough of belt to be fixed on the support member; Filter frame is formed by a dismountable porous slab or with the detachable porous slab of the interconnective polylith of connected element, can prevent from like this to come off.
The present invention is a kind of compressor air suction mouth baffler, described baffler has a plurality of annular noise reduction parts 2 and 2a, these parts each interval constant distances also are made up of a plurality of piece spares of arranging along peripheral direction 3, and the filter 5 that is arranged in the baffler periphery arranged, it is characterized in that: its agent structure is an one piece casting, the radially casting rib of silencing block 3 usefulness troughs of belt 6 is fixed on the support member, and filter frame is formed by a detachable porous slab 7 or by the detachable porous slab 7 of polylith that connects with connected element 8 each other.
As seen advantage of the present invention mainly is to have simplified assembling, reduced component number except that others, even and the erasure effect of improvement arranged also when the compressor high speed rotating.Orifice plate breaks into circular hole, and silencing block with clamping bolt or clip as connected element, also convenient especially.
Two outside baffler parts are installed on casing wall are made other baffler parts of wall ratio thin, and each baffler parts is made up of a plurality of (preferred 4) silencing block, these also all are favourable.The noise reduction parts are preferably made discoid, but also can do tapered or dish-shaped.Crooked guide element is preferably joined in the interior edge of inner noise reduction parts.The axial depth of two outside noise reduction parts on the shell body wall less than in other noise reduction parts and its along not synthesizing guide element.At last, preferably adopt the filter material of plastics.
One embodiment of the present of invention as shown in the figure, wherein
Fig. 1 represents to have the part longitudinal section of the baffler of disc baffler parts.
Fig. 2 represents part plane view (no filter frame).
Fig. 3 is illustrated near the part viewgraph of cross-section that passes through baffler on the plane of baffler parts front, and arrow marks installation direction.
Fig. 4 represents part plane view (band filter frame).
Only draw among the figure to understanding parts essential to the invention.
In baffler shown in Figure 1, main body is made of an one piece casting.It uses the chill casting manufactured.
Baffler is by being connected such as the silencer casing on the compressor of air-discharging and supercharging device 1 securely, being essentially the discoidal filter 5 that is installed in baffler parts 2 and the 2a in shell 1 inner space and is installed on shell 1 periphery and forming.Baffler parts 2 edge within it form crooked guide element 4, thereby have avoided the eddy current loss of new appearance shunting to a great extent.Be positioned at the outside baffler parts of disc 2a on the casing wall and have only half of baffler parts 2 axial depth usually, and do not have guide element 4.
Baffler parts 2 and 2a form by 4 silencing blocks 3, and this can be as can be seen from Figure 3.Silencing block 3 is made by two blocks of porous slabs of splitting that support quieter material.
The assembling of silencing block 3 is very simple, and can be as can be seen from Figure 3.Silencing block 3 is from radially advancing main body, and fixing with the groove 6 of radially arranging.Filter 5 is radially clamping and fixing silencing block 3.With prior art relatively, needn't be with the fixing silencing block of rivet, thus reduced matching requirements.
In addition, no longer need to clamp silencing block 3 with tie-rod, because main body has only parts, even vibrating under the very strong situation, baffler totally also is a very stable system.Necessary keeping by means of the interval axle sleeve according to prior art at interval between the baffler parts 2 is so matching requirements reduce once more.
The filter frame design also brings further advantage.This is formed by a round-meshed porous slab 7, in another embodiment according to Fig. 4, is to be formed by the round-meshed porous slab 7 of polylith perhaps, and these porous slabs link together with connected element 8.Connected element 8 preferred clip or screw type link or clamping bolts.Pull down grid 9, filter material can be taken out, and need not to dismantle filter frame and can easily clean.Than previously used delthyrium porous slab, the circular hole of porous slab 7 makes that the crosspassage area is bigger, thereby has reduced the pressure loss on the filter.
As filter material, by grid 9 it is compressed into filter frame with plastics from the outside.Under the situation of the original copper material that adopts usually, filter material often ruptures when judder, causes bigger foreign material to enter compressor and makes it to suffer damage.Then can avoid this situation with plastics.
