This invention relates to a cloth hanging device.

Prior Art A cloth is hung from a cloth hanging rod suspended parallel to the board above the space between the boards to cover the board, and when the board is opened, the cloth hanging rod is moved parallel to the board to the middle of the opening frame interval. A cloth hanging device for a filter press is known, which separates the cloth from a plate and shakes off cake adhering to the cloth from the cloth.

In order to hang the above cloth hanging rod parallel to the boards above the space between the boards, use the tip of the cloth hanging rod with one end pivoted on the side of the board, and the cloth hanging bar with one end pivoted on the side of the board adjacent to the board. A device is known in which the tips of the rods are connected with a connecting pin, and the cloth hanging rod is hung between the lower end of the spring suspended from the pin and the lower end of the spring similarly suspended on the opposite side of each plate. There is also known a device in which hanging springs are suspended from supports erected at both ends of adjacent boards, and the cloth hanging rod is suspended parallel to the boards above the space between the adjacent boards via the springs.

Problems to be Solved by the Invention In the above-mentioned conventional cloth hanging device, the cloth hanging rod follows the open frame of the board and is moved parallel to the board to the middle of the open frame interval, and the cloth hung on the cloth hanging rod is moved parallel to the board to the middle of the open frame interval. In the process of being pulled away from the plate, it is subjected to vertical and horizontal vibrations parallel to the plate. Further, when the cloth is locked at the lower end or the middle of the plate, the cloth is tilted between this locking portion and the cloth hanging rod and is subjected to the above-mentioned vibration. The cake adhering to the cloth is shaken off by the vibrations that the cloth receives.
However, depending on the adhesion of the cake to the cloth,
The above vibration-induced shaking-off action may not be able to easily shake off the cake from the cloth. Furthermore, when the cloth is locked to the plate, the above-mentioned vibration is suppressed by the locking portion of the cloth.

Means for Solving the Problems The present invention was completed as a result of extensive studies regarding the insufficiency of shaking off the cake with the above-mentioned conventional cloth hanging device. That is, the present invention provides a cloth hanging device for a filter press in which the cloth hung between the plates is separated from the plates by opening the frames of the plates, and the cake is shaken off from the cloth. The ends of the cloth are connected to one hanging support located above one plate, and the other hanging support end of the cloth is connected to another hanging support located above the other plate, and the opening of the plate is connected. The frame is configured so that the positions at which the one hanging support end and the other hanging support end of the plate are separated from the plate are made different between the plates.

The lower ends of the springs 7 and 8 are connected to each other by a hanging string 9, and the upper 3 parts of the cloth are hung through the string, and the both ends 4 and 5 of the cloth and the hanging string 9 are fastened so that they do not shift. There is.
In both the open frames 1A and 1B, the upper sides 3 of the cloth are diagonally arranged as shown in FIGS. 2 and 3, and are pulled in opposite directions from both ends 4 and 5,
Cloths 2A, 2B are separated from plates 1A, 1B. At this time, the suspension string 9 may be omitted, and one end 4 of the cloth may be connected to the suspension spring 7, and the other end 5 of the cloth may be connected to the suspension spring 8, respectively.

Further, the cloths 2A and 2B are applied to the front and back surfaces of the plates 1A and 1B, respectively, and are connected to each other in the usual manner by passing the cloth stock solution hole through the stock solution hole provided in the center of the plate. Further, the lower ends of the cloths 2A, 2B are hung on cloth fixing rods 10, 10, which are hung from inverted L-shaped fittings 11, 11 attached to both sides of the lower portions of the plates 1A, 1B, respectively. FIG. 4 shows the cloths 2A and 2B cut from the center along with one of the plates 1B in the direction of opening the plates. That is, this cloth 2
When the boards are tightened, A and 2B are attached along the board as shown in FIG. It is pulled towards the 6A side and the cloth upper side 3
As it goes downwards, the one end 4 side is tightened, and the other end 5 side on the opposite side is relaxed and opened to follow the frame being opened, and the other end 5 of the cloth 2A side is tied to the above-mentioned hanging string 9. The cloth is drawn toward the support column 6B by the suspension spring 8 via the hanging spring 8, and as it goes downward from the upper side 3 of the cloth, the other end 5 side is tensed, and the one end 4 side on the opposite side is relaxed and opened. The plate-opening frame applies tension and relaxation in the oblique direction to the cloth being swung. Therefore, the cake adhering to the cloth is forcibly shaken off, and the cake that has gotten into the weave of the cloth and adheres to it is also thrown out from the weave. In the above example, cloth 2A, 2
The stock solution hole part B is locked to the stock solution hole provided in the center of plates 1A and 1B, but the locking of this cloth to the plate may be moved to the lower part of the plate as shown in the examples in Figures 6 to 8. .
