Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1, an exhaust duct for a grinding machine comprises an exhaust duct body, wherein the exhaust duct body comprises an inner pipe body 1 and an outer pipe body 2 sleeved outside the inner pipe body 1;
one end of the outer tube body 2 is of a closed structure, and the other end of the outer tube body is of an open structure;
one end of the inner tube body 1 is fixedly connected with the closed end of the outer tube body 2, and the other end of the inner tube body extends towards one side of the closed end of the outer tube body 2 and is coaxially arranged with the outer tube body 2;
a plurality of air inlet pipes 3 are communicated with the inner pipe body 1, and the air inlet pipes 3 penetrate through the side wall of the outer pipe body 2 downwards;
the side wall of the inner tube body 1 is provided with a plurality of first pressure relief air guide holes 4.
A plurality of supporting clapboards 5 are arranged between the inner pipe body 1 and the outer pipe body 2, and the supporting clapboards 5 are of a square-back structure;
and a plurality of second pressure relief air guide holes 6 are formed in the supporting clapboard 5.
The arrangement distance between two adjacent support clapboards 5 is gradually increased from the closed end to the open end of the outer tube body 2.
The lower end of the air inlet pipe 3 is connected with a flexible air duct 7.
The outer pipe body 2 and the inner pipe body 1 are both stainless steel pipes.
In this embodiment: through outer body 2 and the external mode of interior body 1 suit and interior body 1 through air-supply line 3 intercommunication, air-supply line 3 is used for being connected with the air exit of polisher, with polisher exhaust air leading-in interior body 1 in, after the air got into interior body 1, partly is discharged by the open end of interior body 1, another part will flow into the space between interior body 1 and outer body 2 by first pressure release air guide hole 4, can reduce the vibrations to outer body 2, reduce the noise that vibrations formed, also can outwards derive dust and the fog that produces with polishing simultaneously, make operation workman's station environment improve.
