Abstract
The utility model discloses an air-filtering silencer. The air-filtering silencer comprises an air-ejecting device, a filtering assembly and a hose communicated with the filtering assembly and the air-ejecting device. The filtering assembly comprises a hollow filtering barrel and a filtering net, an air inlet and an air outlet are formed in the filtering barrel, the filtering net is arranged at the air inlet, and the air outlet is connected with the hose. The air-filtering silencer can carry out air silencing simply and ingeniously and meanwhile achieves air filtering.
Description
Technical field
The utility model relates to a kind of air borne sound insulation filtrating equipment.
Background technique
Can often use pneumatic system at medical equipment, in pneumatic system, have the pneumatic element of air stream drives.In pneumatic system, air-flow, in adding air pump, adds in normal working conditions air pump and has very large noise.For the elimination of noise, do not have at present simple method, conventionally or from optimizing and add air pump in essence, reduce the noise of noise source, or whole device is sealed as far as possible and increased the sound arrester of acoustical cotton and so on therein, reduce overflowing of noise.And these two kinds of modes, the former technical sophistication, is difficult to realize or with high costs and unrealistic, and the latter's apparatus structure complexity, cost improve, and enclosed scheme has again considerable restraint, and a lot of scenes cannot be applied.
In addition, what drive pneumatic element must be the clean air through filtering, if air-channel system has other impurity to sneak into, expensive pneumatic element is very easily damaged, conventionally needs gas circuit filtrating equipment.The existing filter process that adds air pump narrow-minded, once and blocked rear very difficult cleaning, filter is exactly to scrap substantially.
Model utility content
The purpose of this utility model is: propose a kind of simply, realize airfiltering device when carrying out air borne sound insulation dexterously.
The purpose of this utility model realizes by following technical proposals:
A kind of air-filtering silencer, comprise aerator, also comprise the flexible pipe of filter assemblies and the described filter assemblies of connection and aerator, described filter assemblies comprises hollow cartridge filter and filter screen, described cartridge filter is provided with air inlet and air outlet slit, described air inlet is provided with described filter screen, and described air outlet slit connects described flexible pipe.
In such scheme, not as usual manner is directly communicated with and fixes an air filter just like that on aerator, inventor finds: by the filtering head of a hollow shell (with the cartridge filter of filter screen), an and flexible pipe, and by flexible pipe, both are communicated with, the hoseline of the cartridge filter of the large cavity of rigidity that utilization is connected and long thin flexible cavity, can by noise simply, be absorbed in a large number dexterously in the propagation process of cartridge filter and flexible pipe, greatly reduce finally overflowing of noise, and cartridge filter also plays airfiltering effect simultaneously.
As selection, described flexible pipe spiral close-packed arrays is wound in described cartridge filter outer wall.
In such scheme, close-packed arrays between the each circle of flexible pipe, and with cartridge filter outer wall close contact, and the direction of propagation spiral of air in flexible pipe around air the direction of propagation in cartridge filter, realize thus better erasure effect.
As further selection, described air inlet and air outlet slit split described cartridge filter two ends, and described flexible pipe from described air outlet slit around to air inlet.
In such scheme, the spiral direction of propagation of air in flexible pipe, the direction of propagation with air in cartridge filter is reverse, realizes thus better erasure effect.
As selection, described cartridge filter is a cylinder, and its axial end opening, to should opening being provided with the cover of filter screen and fixing filter screen.
In such scheme, the size of the area of the filter screen number of the amount of regulating the flow of vital energy and air quality and adjust everywhere.Can process larger tolerance, and the contaminated situation of cartridge filter can be from outer observation, even if cleaning in time.
As further selection, described air outlet slit is located on the barrel of described cartridge filter.
As selection, described flexible pipe is silica gel hose.
As further selection, the external diameter of described silica gel hose is that 6mm, wall thickness are 1.5mm.
In such scheme, inventor finds through repetition test, adopt silica gel hose, and its size Control just can reach best erasure effect in aforementioned range.
The main scheme of aforementioned the utility model and each further selection scheme thereof can independent assortment to form multiple schemes; be the utility model and can adopt also claimed scheme: as the utility model; each selection can be selected combination in any with other; those skilled in the art can understand there is multiple combination according to prior art and common practise after understanding the present invention program, do not do exhaustive at this.
The beneficial effects of the utility model: can be simply, realize air-filtering when carrying out air borne sound insulation dexterously.
Brief description of the drawings
Fig. 1 is the utility model embodiment's structural representation;
Fig. 2 is the utility model embodiment's cross-sectional schematic.
Embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is further described.
As shown in Figure 1, 2, a kind of air-filtering silencer, comprise aerator (adding air pump), also comprise the flexible pipe 20 of filter assemblies 10 and connection filter assemblies 10 and aerator, filter assemblies 10 comprises hollow cartridge filter 1(aluminum barrel) and filter screen 3(stainless (steel) wire 200 orders), cartridge filter 1 is provided with air inlet 101 and air outlet slit 102, and air inlet 101 is provided with filter screen 3, air outlet slit 102 connecting hoses 20.Cartridge filter 1 is a cylinder, and its axial end opening, to should opening being provided with the cover 2 of filter screen 3 and fixing filter screen 3.Cover 2 and filter screen 3 are fixing with cartridge filter 1 by aluminum rivet 4, are also fixed with compressing tablet 5, in order to be fixedly wound in the flexible pipe 20 on cartridge filter 1 barrel on cartridge filter 1 barrel.Air outlet slit 102 is located on the barrel of cartridge filter 1.Flexible pipe 20 is silica gel hose.The external diameter of silica gel hose is that 6mm, wall thickness are 1.5mm.Be 40 watts when adding the power of air pump, the length of glue flexible pipe is 1500mm.Flexible pipe 20 spiral close-packed arrays are wound in cartridge filter 1 outer wall.Air inlet 101 and air outlet slit 102 split cartridge filter 1 two ends, and flexible pipe 20 from air outlet slit 102 around to air inlet 101.Air after filter screen 3 filters enters silica gel hose 20 from air outlet slit 102, then enters and add air pump.Silica gel hose 20 is connected with the entrance that adds air pump, and noise is by aerating pump intake in 20 li of propagation of silica gel hose, and in the process of propagating, acoustic energy is reflected, absorbs at cartridge filter 1 and silica gel hose 20 inwalls, thereby plays the object that reduces noise.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
