The driving motor 22 is started to drive the transmission shaft 23 to rotate, and the rotation of the transmission shaft 23 drives the dewatering cylinder 2 to rotate, so that the function of driving the dewatering cylinder 2 to rotate is realized.

In the dehydration process of the device, the driving shaft 23 is rotated by starting the driving motor 22, the rotation of the driving shaft 23 drives the dehydration cylinder 2 to rotate, thereby the sewage is discharged from the annular hole of the moving ring 6 under the action of centrifugal force, and impurities in the sewage are retained on the filter screen 7 through the filter screen 7, thereby realizing dehydration and filtration effects, during the dehydration, the air outside the main body 1 is conveyed into the connecting pipe 10 from the fixed pipe 9 through the suction pump 8, the air in the fixed pipe 9 is conveyed into the air bag 11 through the air pipe 12, the volume of the air bag 11 is increased, thereby the water level height of the sewage in the dehydration cylinder 2 can be improved, the filter screen 7 is positioned below the water level, the impurities are automatically filtered through the fluidity with the sewage, meanwhile, the air pressure in the dehydration cylinder 2 can be increased through the volume increase of the air bag 11, further the sewage is extruded and is discharged out of the dehydration cylinder, and the dehydration efficiency is improved, when the dehydration is finished, the sealing plate 5 is reset under the self gravity and plugs the dehydration hole, then, the suction pump 8 reciprocates to realize the suction of air, when the suction pump 8 sucks the air in the connecting pipe 10 through the fixed pipe 9, the air of the air bag 11 is discharged and the volume of the air bag 11 is reduced, at this time, the push plate 15 is moved towards the direction close to the axis of the main body 1 in the auxiliary pipe 13 under the action of the air pressure, the spring 17 is stretched, the movement of the push plate 15 drives the moving ring 6 to realize the synchronous movement through the push rod 16, when the suction pump 8 conveys the ventilation finished main body 1 into the connecting pipe 10 through the fixed pipe 9, the volume of the air bag 11 is increased, the air pressure in the dehydration cylinder 2 is increased, the sealing plate 5 rotates under the action of the air pressure, so that the air in the dehydration cylinder 2 is discharged, the push plate 15 is reset under the elastic action of the spring 17, the reset of the push rod 16 drives the moving ring 6 to reset, so circulate, realized the reciprocating motion of shift ring 6, when shift ring 6 moves towards being close to main part 1 axis direction and changes into when keeping away from main part 1 axis direction and remove, make impurity and filter screen 7 separation on the filter screen 7 under inertial effect, realized cleaing away the function of impurity on the filter screen 7, avoid impurity to reduce the filtration efficiency of filter screen 7.

Compared with the prior art, this a centrifugal dewatering equipment of high-efficient type for industry has realized the effect of dehydration through dehydration mechanism, compares with current dehydration mechanism, and this dehydration mechanism has still realized the function of cleaing away impurity on the filter screen 7, has improved dehydration efficiency, moreover, has still improved dehydration efficiency through complementary unit, compares with current complementary unit, and this complementary unit has still realized the function that drive push pedal 15 removed, and the practicality is stronger.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
