。(Means for Solving the Problems) The present invention addresses the above-mentioned problems, and during the filtration process in which a rotating body enters the slurry in a slurry tank, the negative pressure inside the rotating body causes the solid content in the slurry to be reduced. It is attached to the surface of the rotating body and during the dehydration process when it comes out of the gas slurry of the two rotating bodies, the water in the solid content is dehydrated by the negative pressure inside the rotating body and turned into a cake. In a vacuum dehydrator that uses a purge pressure to peel off the adhering cake and discharge it out of the slurry tank, the knock-off arm that swings around the support shaft and knocks off the cake adhering to the surface of the rotating body is the same as the The present invention relates to a vacuum dehydrator characterized in that it is equipped with a swinging drive means for swinging the knock-off arm around the support shaft, and its purpose is to provide an improved vacuum dehydrator that can increase throughput. The point is that it provides a vacuum dehydrator.

軟質材により構成している。Next, the operation of the vacuum dehydrator shown in FIG. 1 will be explained in detail. The disk sector (1) rotates around the rotation axis, enters the slurry in the slurry tank, and passes through the slurry (during the filtration process).
1) The solid content in the slurry is attached to the filter cloth (2) of the disk sector (1) by the negative pressure inside, and when the disk sector (1) comes out from the slurry water surface (during the dewatering process), The negative pressure inside the disk sector (1) sucks out the water in the solids, dehydrates them and turns them into a cake. The adhering cake is peeled off by the hack purge air inside. At this time, the knock-off arm (13) swinging in the direction of the arrow knocks off the cake attached to the disk sector (1). In addition, the knock-off head (12) provided on the knock-off arm (13)
) is rounded so as not to damage the filter cloth (2) on the disk sector (1), and is made of a soft material such as synthetic resin, bamboo, or wood.
