Abstract

PURPOSE:To stabilize the circular motion of a head installing stand by a simple construction consisting of a vertically-moving guide member and an advancing and retreating guide member, by transmitting the rotation of a crank driving means to the stand through a crank. CONSTITUTION:In a open state of filter plates, a moving base 5 is pulled by a chain conveyor to move above filter cloths 4. Next, a controlling means for supplying a pressurized air starts to actuate a vertically moving means 13 used for moving a vibrating head 12, which lowers the head 12 to the position where the head 12 acts on a filter-hanging bar 3 as shown by the imaginary line. A freedom of moving in the advancing and retreating, and vertical directions is given to a head installing stand 8 by directly guiding the stand 8 in the advancing and retreating direction with the aids of advancing-and-retreating guiding shafts 7, 7, and also guiding the shafts 7, 7 in the vertical direction with the aids of vertically guiding shafts 6, 6 fixed to the base 5. The bar 3 pressed to the head 12 acts a circular motion and; the filter cloth 4 rocks back and forth, that is, it rocks in the releasing direction of the filter plates, and also vibrates in the vertical direction.

Description

[Detailed Description of the Invention] This invention applies vibration to a p cloth hanging rod installed horizontally in a direction perpendicular to the opening direction of a hanging door plate. This invention relates to a cloth vibrating device for a filter press that vibrates the cloth to shake off p scum adhering to the cloth.
