レスは、すでに公知である。 A filter cloth supported so as to be movable up and down is provided between the filter plates,
Filtration operation is performed with this filter cloth held in the raised position and sandwiched between the filter plates, and the cake adhering to the filter cloth is removed by opening the filter plates and lowering the filter cloth downward between the filter plates. Filter presses designed to do this are already known.

る。 In addition, in order to move the filter cloth up and down between the filter plates as described above, the lower end of the filter cloth whose upper end is moved up and down by the filter cloth driving device is attached to a fixed shaft fixed to the lower part of the filter plate. It is fixed to a take-up roll that can be fitted and rotatably supported, and a coil spring is installed between the fixed shaft and the take-up roll, and the elastic rotational force (restoring force) of this coil spring is applied to the lower end of the filter cloth. For example, a filter cloth winding device for winding up the filter cloth on the winding roll is disclosed in Japanese Patent Publication No. 1983-
37928 and Japanese Patent Publication No. 56-45642.

た。 However, in all of the above-mentioned known filter cloth winding devices, the entire vertical stroke of the filter cloth is covered only by the restoring force of the coil spring, the lower end of the filter cloth is urged downward, and the filter cloth is Since it applies the necessary tension and lowers the lower end of the filter cloth, the winding state of the filter cloth at the beginning when the filter cloth is in the raised position and the end of winding of the filter cloth when the filter cloth is in the lowered position In this situation, the tension applied to the filter cloth changes very rapidly, and in order to minimize this tension change and always apply appropriate tension to the filter cloth, it is necessary to use a filter that is limited by the width of the filter plate. Not only must the long lifting stroke of the filter cloth, which depends on the height of the filter plate, be covered by the smallest possible elastic deformation rate of the coil spring installed in the narrow space, but also each filter cloth must be , when the filter cloth is raised all at once, the load applied to the filter cloth drive device at the filter cloth raising position is
It has the disadvantage that it tends to become too large,
There were problems in that it was difficult to select the spring characteristics of the coil spring, and that a device for lifting and lowering the upper end of the filter cloth required strong power and a strong power transmission system.

足なく円滑に巻取られることになるものである。 Next, the operation will be explained. Since the filter cloth winding device of the embodiment according to the present invention has the above-mentioned configuration, the filter cloth winding device according to the present invention has the above-mentioned configuration, so that the filter cloth winding device according to the embodiment
In the figure), when the filter cloth drive shaft 5 is driven forward or reverse, the endless chain 20 rotates and the filter cloth upper end support bar 23 attached to it moves up and down, and the filter cloths 2 1 and 2 2 are rotated. The upper end moves up and down. When the upper ends of the filter cloths 2 1 and 2 2 move up and down in this manner, the filter cloth winding shaft 15 driven by the chain 20 rotates in the direction of winding up the lower ends of the filter cloths. The lower end portions of 2 1 and 2 2 are not fixed to this filter cloth winding shaft 15, and the coil springs 30
The coil spring 30 is fixedly connected to a rotatable filter cloth take-up roll 25 connected to the filter cloth take-up shaft 15 through the filter cloth take-up shaft 15 . Since the filter cloth is always elastically biased in the winding direction, the surfaces of the filter cloths 2 1 and 2 2 that are located between each filter plate 1 and move up and down are always kept under an appropriate tension by the coil spring 30. In this state, the lower ends of the filter cloths 2 1 and 2 2 are wound up by the driving force input to the chain 20, and the lower ends of the filter cloths 2 1 and 2 2 are wound up by the vertical displacement of the filter cloths. Therefore, even if the portion wound on the filter cloth take-up roll 25 becomes thinner (when the filter cloth is raised) or thickened (when the filter cloth is lowered), the lifting speed of the upper end of the filter cloth always matches the speed of the upper end of the filter cloth. Even at the circumferential speed, winding can be done smoothly without excess or deficiency.

The lower end of the driven filter cloth is not wound up through its entire stroke only by the elastic rotational force of a coil spring, as in known winding devices; The filter cloth is wound up and unwound by the rotation of the filter cloth winding shaft, which is interlocked and connected to the filter cloth drive shaft through an interlocking system consisting of a chain wheel and a chain, and the filter cloth is fixed. An elastic biasing means is interposed between the filter cloth take-up roll and the filter cloth take-up shaft connected to the filter cloth drive source. When the filter cloth is unwound, even if the outer diameter of the wound portion changes in size, the speed of the outer periphery of the winding surface is made to match the lifting speed of the upper end of the filter cloth, so that the filter cloth is constantly Since it is only for applying a substantially constant tension, the amount by which the filter cloth winding roll is rotationally displaced relative to the filter cloth winding shaft by this elastic biasing means is very small. It is.
