≪間接材≫
間接材６としては、加圧ろ布１３間の摩擦を軽減できる公知の技術を採用でき、ここでは回転自在な円筒状のロールを用いる。以下、間接材６として用いるロールを間接ロール６とする。間接ロール６の回転方向が加圧ろ布１３の走行方向と一致しているため、加圧ろ布１３、１３の摩擦は極めて軽減される。また、間接ロール６で構成される加圧ろ布１３、１３間の隙間からろ液が排出されることもあり、複数のロールを間接ロール６として用いることが好ましい。間接ロール６は中心ロール１の中心から放射線状に移動自在に配設してある。そのため、間接ロール６の外側を走行する加圧ろ布１３の張力により、間接ロール６を介して中心ロール１に当接したろ布２に圧力を加える。従って、中心ロール１に当接したろ布２には、中心ロール１の面圧、加圧ろ布１３の押しつけ力と共に、間接ロール６の押しつけ力による線圧も加わるため、高圧の脱水が行われる。
また、本発明では間接ロール６の移動方向を放射線状としているが、移動方向としては放射曲線状、あるいは平行状等、間接ロール６が中心ロール１の円周面から離接自在であればどのような移動方向としてもよい。
≪Indirect material≫
As the indirect member 6, a known technique that can reduce friction between the pressure filter cloths 13 can be adopted, and here, a rotatable cylindrical roll is used. Hereinafter, the roll used as the indirect material 6 is referred to as an indirect roll 6. Since the rotation direction of the indirect roll 6 coincides with the traveling direction of the pressure filter cloth 13 , the friction of the pressure filter cloths 13 and 13 is extremely reduced. Further, the filtrate may be discharged from the gap between the pressure filter cloths 13, 13 configured by the indirect roll 6, and it is preferable to use a plurality of rolls as the indirect roll 6. The indirect roll 6 is disposed so as to be movable radially from the center of the center roll 1. Therefore, pressure is applied to the filter cloth 2 that is in contact with the center roll 1 via the indirect roll 6 due to the tension of the pressure filter cloth 13 that travels outside the indirect roll 6. Accordingly, since the filter cloth 2 in contact with the center roll 1 is also subjected to linear pressure due to the pressing force of the indirect roll 6 in addition to the surface pressure of the center roll 1 and the pressing force of the pressurized filter cloth 13, high pressure dehydration is performed. Is called.
In the present invention, the moving direction of the indirect roll 6 is a radial shape. However, the moving direction may be a radial curve shape, a parallel shape, or the like as long as the indirect roll 6 can be separated from the circumferential surface of the center roll 1. Such a moving direction may be used.

Claims

The indirect roll ( 6 ) is supported by a frame (10) erected on both ends of the center roll (1), and the frame (10) supports a support hole (in which the indirect roll (6) can be inserted and moved. The belt press according to any one of claims 2 to 5, wherein 12) is provided.
