The beneficial effects of the utility model reside in that: the air inlet sound-proof box is arranged at the air inlet of the compressor, and the noise is reduced through the circuitous channel and the sound-proof plate in the box body, so that the structure is simple and compact, the size is small, and the sound-proof effect is good.
Description
Technical Field
The utility model relates to a compressor technical field especially relates to a sound-proof box admits air on compressor.
Background
The compressor inevitably generates noise during operation, and therefore, the reduction of the noise of the compressor is a major concern of the industry. The existing mode for reducing the noise of the compressor is generally provided with a sound-proof cover outside the compressor, so that the volume of the compressor is increased, and the sound-proof effect is poor.
Disclosure of Invention
In order to overcome the defects in the prior art, the utility model provides an air inlet sound-proof box with simple structure, small volume and good sound-proof effect.
The technical proposal of the utility model for solving the technical problem is that: the utility model provides a soundproof box admits air, includes the box, is equipped with the passageway in this box, and the both ends of this passageway are the inlet end respectively and give vent to anger the end, lie in the passageway be provided with the polylith acoustic celotex board between inlet end and the end of giving vent to anger side by side, the polylith the acoustic celotex board will a plurality of sound insulation cavities, every are separated into to the passageway on the acoustic celotex board perhaps every the acoustic celotex board with between the box or with every be equipped with the UNICOM on the box in the position that the acoustic celotex board is relative adjacent the intercommunication mouth of sound insulation cavity, and adjacent the.
Preferably, the soundproof panel includes soundproof cotton and a metal splint sandwiching the soundproof cotton.
Preferably, the metal clamping plates are latticed plates and are connected through fixing screws.
Preferably, the passage is provided with a slot for inserting the sound insulation board.
Preferably, an n-shaped fixing frame is arranged in the channel, and the inserting groove is formed in the fixing frame.
Preferably, one of the two adjacent communication ports is provided at an upper portion, and the other communication port is provided at a lower portion.
The beneficial effects of the utility model reside in that: the air inlet sound-proof box is arranged at the air inlet of the compressor, and the noise is reduced through the circuitous channel and the sound-proof plate in the box body, so that the structure is simple and compact, the size is small, and the sound-proof effect is good.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 ~ fig. 3, a sound insulation box admits air, including box 1, the box comprises case seat and case lid, and the opening part at the case seat is fixed to the case lid, is equipped with the passageway in this box, and the both ends of this passageway are inlet end 2 and the end 3 of giving vent to anger respectively, lie in the passageway be provided with polylith acoustic celotex board 4, polylith between inlet end and the end of giving vent to anger side by side the acoustic celotex board will a plurality of sound insulation cavity 5, every on the acoustic celotex board or every the acoustic celotex board with between the box perhaps with every be equipped with the UNICOM on the relative position of acoustic celotex board adjacent the intercommunication mouth 6 of sound insulation cavity, and adjacent intercommunication mouth 6 sets up that staggers each other, the utility model discloses install in the inlet air department of compressor, gas gets into in the passageway through inlet end 2, then through the end 3 of giving vent to anger, owing to set up polylith acoustic celotex 4 in the passageway, and intercommunication mouth 6 on the polylith acoustic celotex board staggers each other and sets up, makes.
Preferably, the soundproof panel 4 includes soundproof cotton 41 and metal plywood 42 holding the soundproof cotton therebetween, the metal plywood is a mesh-shaped panel, and the metal plywood is connected to the metal plywood by a fixing screw, so that the soundproof cotton 41 is held between the metal plywood 42.
Preferably, an n-shaped fixing frame 7 is arranged in the channel, a slot 8 is formed in the fixing frame, and the edge of the sound insulation board 4 is inserted into the slot 8, so that the installation is convenient.
Preferably, one of the two adjacent communication ports 6 is disposed above the other communication port 6, and the layout is reasonable.
The above is only the preferred embodiment of the present invention, but the present invention is not limited to the above embodiments, and the technical effects of the present invention should fall into the protection scope of the present invention as long as it is reached by any of the same or similar means.
