Description
Technical field
The present invention relates to a kind of compressor noise-reduction filter devices, belong to gas filtration technical field.
Background technique
The medical instruments such as ventilator and Anesthesia machine are required to use air compressor, and compressor inlet will use filtering dress
Set, since compressor inlet air velocity is fast, so at air inlet wind make an uproar it is larger, and in medical field to wind make an uproar requirement compared with
Height, current filtering device of compressor noise reduction effect can not reach requirement.
Summary of the invention
In order to solve the problems in the existing technology the present invention, provides a kind of apparent compressor noise-reduction mistake of noise reduction effect
Filter device.
In order to achieve the above object, technical solution proposed by the present invention are as follows: a kind of compressor noise-reduction filter device, including mistake
Filter seat and strainer cover, the filter seat front end is connect with strainer cover rear end, after filter seat is connected with strainer cover
Inside forms cavity, and sponge is filled in the cavity, and filter seat rear end is equipped with air inlet, and the strainer cover includes being in
Cylindric interconnecting piece and gas outlet, the interconnecting piece diameter are greater than gas outlet diameter, by slow between interconnecting piece and gas outlet
Portion's connection is rushed, buffer part diameter is gradually reduced from close to interconnecting piece one end to the other end, and several points are equipped on the inside of the buffer part
Flowing plate, the flow distribution plate are arranged radially along buffer part.
Be further designed to above-mentioned technical proposal: the filter seat is in the tubular of front opening, and rear end is circular arc
Face offers several air inlets on the arc surface.
The air inlet is the sector of smoothed curve in edge.
Several air inlets are uniformly arranged along same circular arc.
The arc surface of the filter seat is equipped with annular groove in inner peripheries.
Several flow distribution plates are in the same plane in the end face close to interconnecting piece side.
The invention has the benefit that
Strainer cover interconnecting piece is connected between gas outlet by buffer part in the present invention, and diameter is gently excessive, ensure that air-flow
Stability, buffer part inside are equipped with several flow distribution plates, shunt to air-flow, guarantee that air-flow will not be by heavy caliber moment to osculum
Diameter is mutated and causes birdie, effectively reduces pneumatic noise.
Air inlet in filter seat is the scallop hole of edge-smoothing, and is located on curved end, guarantees gas in air inlet
Mouth is not in sharp airflow noise, inside gentle inflow filter seat.
It is equipped with annular groove inside filter seat, filtering sponge can be played and positioned well, not when air-flow passes through
It can swing and cause flow perturbation.
The sponge of filter device central filler of the present invention can guarantee that gas flow is unaffected, and can be reduced gas
Flow noise.

Specific embodiment
With reference to the accompanying drawing and specific embodiment the present invention is described in detail.
Embodiment
As shown in Figure 1, a kind of compressor noise-reduction filter device of the present embodiment, including filter seat 1 and strainer cover 3,
1 front end of filter seat is connect with 3 rear end of strainer cover, internal after filter seat 1 and the connection of strainer cover 3 to form cavity, cavity
It is interior to be filled with sponge 2.
In conjunction with shown in Fig. 2 and Fig. 3, filter seat 1 is in the tubular of front opening, and rear end is arc surface 12, on arc surface 12
Several air inlets 11 are offered, the air inlet 11 is the sector of smoothed curve in edge, and gas has air inlet to enter filter
Sharp noise will not be generated.There are four air inlet 11 is set in the present embodiment, and it is uniformly arranged along same circular arc.
The arc surface 12 of filter seat 1 is equipped with annular groove 13 in inner peripheries in the present embodiment, and annular groove can be to sea
Silk floss is positioned.
In conjunction with shown in Fig. 4 and Fig. 5, strainer cover 3 includes cylindrical interconnecting piece 31 and gas outlet 33, interconnecting piece 31
Diameter is greater than 33 diameter of gas outlet, is connected between interconnecting piece 31 and gas outlet 33 by buffer part 32, and 2 diameter of buffer part is from close
31 one end of interconnecting piece is gradually reduced to close to 33 one end of gas outlet, and diameter is flat during air-flow has interconnecting piece 32 to enter gas outlet 33
It is slow excessively to ensure that the stability of air-flow, eight flow distribution plates 34 are equipped on the inside of buffer part 32, flow distribution plate 34 is along buffer part radial direction
Setting, and be circumferentially uniformly arranged along buffer part, flow distribution plate can shunt air-flow, and air-flow is made uniformly to flow into gas outlet 33,
Reduce gas to make an uproar.
Eight flow distribution plates 34 are in the same plane in the end face close to 31 side of interconnecting piece in the present embodiment, eight shuntings
The end face of plate 34 can resist sponge end, and keep sponge regular close to gas outlet one end end shape, and air-flow can uniform and stable
Outflow sponge, and enter gas outlet, noise can be reduced.
Technical solution of the present invention is not limited to the various embodiments described above, all technical solutions obtained using equivalent replacement mode
It all falls in the scope of protection of present invention.
