[Detailed Description of the Invention] [Industrial field of application] This invention is a filter press in which a large number of plates are arranged in parallel on a horizontally provided guide rail, and a cloth provided between these plates is vertically moved. The improvement of the cloth hanging device.

[Conventional technology]

Conventionally, as a cloth suspending device in the seed cloth traveling type filter press, the cloth hanging device shown in FIGS. 11 to 14 of Japanese Patent Publication No. 52-6903 is shown in FIG. Four
Some are shown in the figure.

In Japanese Patent Publication No. 52-6903, a pair of cloths provided between the plates are joined at their upper ends, and an upper support bar is provided at the joining portion, and the lower ends of the left and right fabrics are made into the left and right plates. After wrapping around the roller provided at the bottom of the, it is attached to the bottom of the cloth in the next room, and the lower support bar is provided at this attachment part,
The lower support bar and the upper support bar are connected by a chain wound around a sprocket provided on the upper part of the plate, and the one shown in Japanese Utility Model Publication No. 54-32284 is provided between the plates. The upper ends of a pair of cloths are joined together with a connecting bar, the lower ends of the left and right cloths are wound around rollers provided at the bottom of the plate, and then fixed to the cloth hanging hardware. When the cloth is run, when the upper end of the cloth is lowered between the plates, the lower end edge of the cloth is raised and these intersect.

[Problems to be solved by the invention]

Conventionally, in a filter press, the excess area, that is, excess capacity is determined by the number of plates that can be arranged in parallel in a fixed space.
Therefore, in the case of running the cloth as described above, a margin for avoiding the interference of the cloth support tool is required in addition to the margin for traveling the cloth, and this margin is required for each plate. However, there is a problem that a large number of plates (overrooms) are greatly restricted by overcapacity.

[Means for solving problems]

Therefore, this invention solves the problem by devising the structure of the cloth and the means for suspending the cloth. The solution is as follows.

(1) A large number of plates are movably arranged side by side on a horizontally provided guide rail, and upper and lower edges of a cloth provided between the plates cross each other to run vertically. In the filter press, the upper edge of a pair of cloths provided between the boards and covering the overbed of the left and right boards are joined together via a support bar, and the lower edge of the left and right cloths are joined to the lower part of the left and right boards. A cloth tensioner is provided around each of the rollers provided on the upper part of the cloth, and the cloth at the lower edge of the cloth can be tensioned in the width direction. Further, the lower edge of the cloth and the support bar are provided as a plate. It was connected by a drive band that was wound around a drive wheel provided at the top of the.

(2) In (1) above, the lower end edges of one of the pair of cloths provided between adjacent plates after the pair of lower end parts provided between the plates are wound around rollers provided at the lower part of the plates. And a cloth tensioner capable of tensioning these cloths in the width direction is provided at the joining portion, and further, the lower end edge of these cloths and the upper support bar of the cloth are provided at the upper part of the plate. It was connected to the drive belt that was wound around the drive wheels.

[Action]

In the hanging of the cloth configured in this way, among the upper and lower edge portions of the cloth, since the lower end edge portion does not have the conventionally required supporting bar, even if the cloth is run by discharging the cake,
There is no possibility that the upper support bar will come into contact, and it is possible to prevent an accident such as pinching the eccentric support bar during the conventional closing plate. Further, the cloth tensioner provided in place of the conventional lower support bar tensions the cloth in the width direction, and the edge of the cloth does not interfere with the upper support bar. Can be prevented. It should be noted that the cloth tensioner is sufficient to tension the cloth as compared with the conventional cloth support bar, and there is no fear that it will interfere with the upper support bar.

As described above, in the device according to the present invention, it is possible to completely prevent the interference between the upper and lower support bars, which occurs when the cloth travels, and to reduce the plate spacing by an amount corresponding to the thickness of the lower support bar. It is possible. Specific structures and actions will be described in Examples.

〔Example〕

In FIG. 1, reference numeral 1 is a frame, 2 is a guide rail,
3 is a large number of plates arranged in parallel, 4 is a link chain that connects the plates loosely, and 5 is an endless drive band for opening and closing the plates. The upper side of its circumference is the movable head 6 on the left side in the figure and the lower side is the right side. It is attached to the movable head 7. Reference numeral 8 is a hydraulic cylinder for tightening the closed plates.

Next, a cloth suspension mechanism that is suspended between the plates will be described. In FIG. 2 and FIG. 3, reference numeral 9 is a pair of cloths provided between the plates so as to cover the oversurfaces of the left and right plates, respectively, and the upper edge of the cloth is the support bar 10.
, And the lower end edge is wound around the roller 11 provided at the lower part of the plate 3 and then the other roller 11 provided at the lower part of the plate 3 is provided between the adjacent plates. A cloth tensioner 12 is provided which is attached to the lower end edge of one of the turned cloths 9 and at the lower end edge of the attached cloth 9 which tensions the lower end edges of these cloths 9 in the width direction thereof. Further, a chain in which both ends of the lower edge of the cloth 9 and the both ends of the upper support bar 10 of the cloth 9 are wound around a drive sprocket 13 provided on the plate 3, respectively.
Connected at 14.

The cloth 9 provided between the plates is a drive sprocket.
It is driven by 13 at the same time and travels up and down, but description of this transmission mechanism is omitted.

In order to run the cloth 9 for discharging the cake with the cloth 9 suspending apparatus configured as described above, the drive sprocket 13 is rotated in the direction shown by the arrow (a) in FIGS. The lower end edge of the cloth 9 is pulled up by 14, and the upper support bar 10 of the cloth 9 is accompanied by this.
Is pulled down, that is, the cloth 9 runs downward, and the cake formed between the left and right cloths can be conveyed to the outside of the lower row of the plate rows and discharged. While the cloth 9 is running, the upper edge and the lower edge of the cloth 9 intersect with each other between the narrow plates. However, in the device according to the present invention, the support bar of the cloth 9 which interferes during the conventional crossing is only on the upper part. Therefore, the cloth can be smoothly run without interference. That is, as a replacement for the conventional lower support bar,
12 exists, but when the upper edge and the lower edge of the cloth 9 intersect, the upper support bar 10 of the upper edge of the cloth 9 first intersects with the lower edge of the bonded cloth 9. Then, the cloth tensioner 12 and the upper support bar 10 cross each other. At this time, the lower edge of the cloth 9 has passed through the upper support bar portion, and the cloth tensioner 12 is clearly shown in the drawing. Since it is wrapped by the lower end of the cloth 9 that has passed through, it will not be caught even if it comes into contact.

The above is a case in which the lower end edges of the pair of cloths 9 are passed under the plate 3 and joined to the lower end edges of the cloth 9 between the adjacent plates. According to the present invention, the lower support bar is not provided at the lower end edge of the cloth even when the cloth is folded back between one plate and the cloth can be smoothly run.

[Effect of device]

As described above, the present invention is capable of preventing interference at the time of crossing, which has conventionally been the cause of an accident, in a filter press of the type in which the upper edge and the lower edge of the cloth cross when the cloth is running. However, its structure is simple and it can be manufactured at low cost, and the profit obtained by using the filter press is enormous.
