Description
Technical field
The present invention relates to air compressor machine technical field, especially a kind of totally-enclosed environmental protection silent helical-lobe compressor.
Background technique
Frequency-variable screw type air compressor is a kind of compressor of big capacity, using the stepless speed regulation feature of frequency converter,
It can gently start, be widely used in fluctuating gas consumption bigger occasion；But existing permanent-magnetic variable frequency screw air compressor machine exists
In use, noise can be bigger, it is necessary to improve.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of totally-enclosed environmental protection silent helical-lobe compressor.The present invention
Solving technical solution used by its technical problem is:
Totally-enclosed environmental protection silent helical-lobe compressor, including fully closed shell are provided at the inner sidewall of the shell
Centrifugal blower, the shell correspond to the air inlet that air-inlet window is provided at centrifugal blower as centrifugal blower, on the upside of the shell in
Oil gas cooler is provided at wall.
As a preference, door-plate is provided on the shell, the edge of the door-plate is provided with sealing strip, wherein institute
State the vertical portion that sealing strip includes the planar portions being bonded with door-plate and is distributed in planar portions.
As a preference, the shell is built-in with host, and the host bottom is provided with damper.
As a preference, flexible conduit is provided on the host.
As a preference, the edge of the door-plate to reverse side bending Formation cross-section be rectangular frame, the sealing
Item is located on frame.
The beneficial effects of the present invention are: being inhaled using centrifugal blower toward box house by the design of exhausting in centrifugal blower
Wind, it is possible to reduce sound transmits outward, effectively reduces the noise effect of helical-lobe compressor.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is perspective view of the invention；
Fig. 2 is schematic diagram of internal structure of the invention；
Fig. 3 is the partial enlarged view of middle door-plate part of the present invention.
Specific embodiment
It is with reference to the accompanying drawings and embodiments, right in order to which the objects, technical solutions and advantages of the application are more clearly understood
The present invention is further elaborated.For the thorough explanation present invention, some certain details can be related in following description
Section.And in these no specific details, the invention can still be realized, i.e., the technical staff in fields uses herein
These describe and state that the others skilled in the art into fields can more effectively introduce their work essence.
Referring to Fig.1, Fig. 2, a kind of totally-enclosed environmental protection silent helical-lobe compressor, including fully closed shell 1, totally enclosed type
Design, which itself has, helps reduce noise from the releasing of shell 1, also can avoid compressor oil leak and leaks to ground, avoids producing environment
Raw pollution.It is provided with centrifugal blower 2 at the inner sidewall of shell 1, is provided with air-inlet window 3 as centrifugation at the corresponding centrifugal blower 2 of shell 1
The air inlet of blower 2 is provided with oil gas cooler 4 at 1 upper inside walls of shell.Only opened up on the door-plate of centrifugal blower installation
The air inlet of one mountable centrifugal blower ventilating duct size, since centrifugal blower 2 is toward 1 box house air draught of shell, just with
Sound transmits contrary outward, can play the role of that host operating sound is prevented to leak.It is mixed that oil gas cooler 4 is called oil gas
Cooler is closed, includes oil duct, air flue and fin, is commonly used in helical-lobe compressor, specific structure and working principle are herein
It repeats no more.Centrifugal blower 2 after air draught, is drained into inside fully closed shell 1 in air, in 1 inside shape of shell
At positive pressure (wind pressure is greater than external atmosphere pressure), under the action of pressure difference, by the outer fin channels of oil gas cooler 4, heat is carried out
It after exchange, enters in outside air, the gas feed of oil gas cooler 4 connects the pressure maintaining valve outlet at the top of oil content barrel, out
Mouth connection supply air line, to the place gas supply needed with gas.
Be provided with door-plate 5 on shell 1, referring to Fig. 3, the edge of door-plate 5 is provided with sealing strip 6, wherein sealing strip 6 include with
The planar portions 61 and the vertical portion 62 being distributed in planar portions 61 that door-plate 5 is bonded, that is, form the sealing strip knot of a similar E font
Structure has been filled up the gap after door-plate installation between shell 1 (such as column, crossbeam, siding of shell etc.), has more effectively been avoided
Sound unofficial biography.The edge of door-plate 5 is rectangular frame 51 to reverse side bending Formation cross-section, and sealing strip 6 is located on frame 51, specifically
It can be installed by stickup or card slot mode, facilitate the firm installation of sealing strip 7.
Shell 1 is built-in with host 7, and 7 bottom of host is provided with damper 8, pointedly plays the role of damping noise reduction.It is main
Flexible conduit 9 is provided on machine 7, flexible conduit 9 will not additionally generate noise when machine vibration, further decrease inside
Shake the noise generated.
According to above-mentioned principle, the present invention can also be made appropriate changes and modifications to the above embodiments.Therefore, this hair
It is bright to be not limited to specific embodiment disclosed and described above, some modifications and changes of the invention should also be as to fall into this
In the scope of protection of the claims of invention.
