Abstract
The utility model discloses a totally-enclosed environment-friendly mute screw compressor, which comprises a totally-enclosed shell, wherein a centrifugal fan is arranged at the inner side wall of the shell, an air inlet window is arranged at the position of the shell corresponding to the centrifugal fan and is used as an air inlet of the centrifugal fan, and an oil-gas cooler is arranged at the inner wall of the upper side of the shell; through the design of convulsions in the centrifugal fan, utilize centrifugal fan to induced draft toward the box is inside, can reduce sound and past conveying outward, effectively reduce screw compressor's noise influence.
Description
Technical Field
The utility model relates to an air compressor machine technical field, especially a totally enclosed environmental protection silence screw compressor.
Background
The variable frequency screw type air compressor is a compressor with large air displacement, can be started smoothly by utilizing the stepless speed regulation characteristic of a frequency converter, and is widely applied to occasions with large fluctuation of air consumption; however, when the existing permanent magnet variable frequency screw air compressor is used, the noise is high, and improvement is needed.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a totally-enclosed environmental protection silence screw compressor.
The utility model provides a technical scheme that its technical problem adopted is:
totally enclosed environmental protection silence screw compressor, including totally enclosed's shell, the inside wall department of shell is provided with centrifugal fan, the shell corresponds centrifugal fan department and opens the air inlet that has the air inlet window as centrifugal fan, shell upside inner wall department is provided with the oil gas cooler.
As a preferred item, be provided with the door plant on the shell, the border of door plant is provided with the sealing strip, wherein the sealing strip includes the plane portion of laminating with the door plant and the vertical portion of distribution on the plane portion. As a preferred item, the shell is internally provided with a host, and the bottom of the host is provided with a shock absorber. As a preferred option, a flexible pipeline is arranged on the main machine.
As a preferred option, the edge of the door panel is bent to the reverse side to form a frame with a square cross section, and the sealing strip is located on the frame.
The utility model has the advantages that: through the design of convulsions in the centrifugal fan, utilize centrifugal fan to induced draft toward the box is inside, can reduce sound and past conveying outward, effectively reduce screw compressor's noise influence.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a perspective view of the present invention;
fig. 2 is a schematic view of the internal structure of the present invention;
fig. 3 is a partially enlarged view of a door panel portion of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. In the following description, certain specific details are set forth in order to provide a thorough understanding of the present invention. Rather, the invention can be practiced without these specific details, i.e., those skilled in the art can more effectively describe the nature of their work to others skilled in the art using the description and illustrations herein.
Referring to fig. 1 and 2, the totally-enclosed environment-friendly silent screw compressor comprises a totally-enclosed shell 1, and the totally-enclosed design is beneficial to reducing noise emitted from the shell 1, and can also prevent oil leakage of the compressor from leaking to the ground and avoid pollution to the environment. The inside wall department of shell 1 is provided with centrifugal fan 2, and shell 1 corresponds centrifugal fan 2 department and opens there is air inlet window 3 as the air intake of centrifugal fan 2, and shell 1 upside inner wall department is provided with oil gas cooler 4. The air inlet which can be provided with the air duct of the centrifugal fan is formed in the door plate which is provided with the centrifugal fan, and the centrifugal fan 2 sucks air towards the inside of the box body of the shell 1, so that the direction of the air suction is opposite to the direction of the sound transmitted outwards, and the air inlet can play a role in preventing the sound of the host from leaking outwards when the host operates. The oil-gas cooler 4 is also called an oil-gas mixing cooler, comprises an oil duct, an air passage and fins, is frequently used in a screw compressor, and the specific structure and the working principle are not repeated. After 2 induced drafts in the middle of the air of centrifugal fan, it is inside to discharge into totally enclosed shell 1, in the inside malleation (the wind pressure is greater than external atmospheric pressure) that forms of shell 1, under the effect of pressure differential, through oil gas cooler 4's outer fin passageway, after carrying out the heat exchange, in the middle of entering into the outside air, oil gas cooler 4's gas inlet connects the pressure retaining valve export at oil branch bucket top, exit linkage air supply line, to the local air feed that needs to use gas.
Be provided with door plant 5 on the shell 1, refer to fig. 3, the border of door plant 5 is provided with sealing strip 6, and wherein sealing strip 6 includes the plane portion 61 of laminating with door plant 5 and the vertical portion 62 of distribution on plane portion 61, forms the sealing strip structure of a similar E font promptly, has filled the gap between door plant installation back and shell 1 (for example stand, crossbeam, wallboard etc. of shell), more effectual sound of avoiding passes outward. The border of door plant 5 is bent to the reverse side and is formed the cross-section and be square frame 51, and sealing strip 6 is located frame 51, and concrete accessible is pasted or the draw-in groove mode is installed, makes things convenient for sealing strip 7 to stabilize the installation.
A host 7 is arranged in the shell 1, and a shock absorber 8 is arranged at the bottom of the host 7 and plays a role in shock absorption and noise reduction in a targeted manner. The flexible pipeline 9 is arranged on the main machine 7, and the flexible pipeline 9 does not generate noise additionally when the machine vibrates, so that the noise generated by internal vibration is further reduced.
According to the above principle, the present invention can also make appropriate changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should fall within the protection scope of the claims of the present invention.
