Part 120 can promote to seal soft fitting 110 in the resume speed that flexible deformation occurs.Specifically, flexible connector 120 can be with
It is set as helical spring.Mounting base, spiral bullet are provided in the part at the both ends for being located at the soft fitting 110 of sealing of shell 100
The both ends of spring can be respectively arranged in mounting base, and helical spring can be welded in mounting base, can also be removable with mounting base
Connection is unloaded, is such as clamped.When shell 100 vibrates, the part sealed above soft fitting 110 that is located at of shell 100 declines, and
The soft fitting 110 of compression seal and flexible connector 120 make to seal soft fitting 110 and flexible connector 120 generate flexible deformation.
Seal soft fitting 110 and flexible connector 120 can generate restoring force while generating flexible deformation, so that shell 100
Rise positioned at the part sealed above soft fitting 110.It so, it is possible the portion for being located at soft 110 top of fitting of sealing for making shell 100
Divide and go up and down repeatedly, and generates vibration during going up and down repeatedly.
Cylinder 130 is formed as the part for sealing the lower section of soft fitting 110 that is located at of shell 100, and the one of flexible connector 120
End is installed on cylinder 130.The inner hollow of cylinder 130, is formed as filter space.The bottom of cylinder 130 is provided with connection
Flange 131, connecting flange 131 are installed on other devices so that filter space is connected to other devices, the air-flow that need to be filtered into
Enter and is filtered inside cylinder 130.
Top cover 140 is covered on the top of cylinder 130, and be formed as shell 100 is located at the portion for sealing the top of soft fitting 110
Point.The soft fitting 110 of sealing is provided between top cover 140 and cylinder 130;Filter mechanism 200, vibrating motor 300 and elasticity are even
One end away from cylinder 130 of fitting 120 is mounted on top cover 140.140 inner hollow of top cover forms the sky of gas circulation
Between, and the air-vent 141 for being connected to the inside of top cover 140 with external environment is provided on top cover 140, gas is through air-vent
141 are discharged outside in environment.Space inside top cover 140 is connected with the filter space inside cylinder 130 by filter mechanism 200
Logical, the air-flow in cylinder 130 is after the filtering of filter mechanism 200, and material resides in the outside of filter mechanism 200, and gas passed through
Filter structure 200 enters in top cover 140.
Orifice plate 150 can be installed on the inner wall of top cover 140, and can follow 140 1 lifting of top cover and vibration.Orifice plate
Cylinder 130 and top cover 140 are divided into above-mentioned two region by 150, to prevent the material in cylinder 130 from entering in top cover 140, and
It is discharged outside in environment, orifice plate 150 is for obstructing material.The peace for installing filter mechanism 200 is offered on orifice plate 150
Hole is filled, cylinder 130 is connected to by filter mechanism 200 with top cover 140.In order to guarantee effectively to seal, sealing is provided at mounting hole
Circle.
In conclusion shell 100 drives the vibration of filter mechanism 200 to shake off the material on 200 surface of filter mechanism, Jin Ergeng
The working principle of the filter area of new filter mechanism 200 are as follows:
Start vibrating motor 300, vibrating motor 300 drives top cover 140 to go up and down, soft 110 He of fitting of 140 compression seal of top cover
Flexible connector 120, so that sealing soft fitting 110 and the generation flexible deformation of flexible connector 120, flexible connector 120 makes
Top cover 140 rises, and aggravates the movement of top cover 140 with this, is installed on the orifice plate 150 inside top cover 140 and also follows 140 liters of top cover
Drop and vibration, and filter mechanism 200 is driven to vibrate, to shake off the material on 200 surface of filter mechanism, update filter mechanism 200
