Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a vibrating device for a cloth in a filter press, and particularly to opening a large number of plates at the same time to vibrate simultaneously the cloths suspended between the plates. The present invention relates to a vibration device for a cloth that peels off slag.

[Prior art]

Conventionally, as a device that opens a large number of plates at the same time, vibrates the cloth stretched on these plates, and separates the slag,
There was a filter press in which a vibration imparting member was made to run along a rail, a spring that hung the cloth was pushed down, and then free return was repeated to give a tapping vibration to the cloth so that the slag was sequentially released (for example, , Mitsuko Sho 56-33614
issue).

[Problems of the prior art] However, in the above-described conventional device, while the vibration imparting member of the cloth is running, the cloth is sequentially vibrated one by one to peel off the slag. If the slag was still attached to a small amount of the cloth, the vibration imparting member had to be run again to sequentially vibrate the entire cloth to separate the slag.
As a result, the miscellaneous time was long. Further, when the cloth bites into the uneven surface of the plate, the cloth is struck downward, so that only the cloth above the plate is bent, and there is a risk that vibration cannot be transmitted to the entire cloth.

[Means for Solving the Problems]

In order to solve the above-mentioned conventional problems, the invention of the present application opens a large number of plates at the same time, and simultaneously vibrates the cloth between the plates while gradually pushing up the support bar of the cloth hanging the cloth. The slag attached to the cloth is peeled off.

That is, the structure is a filter press in which a large number of plates are arranged in parallel on a pair of rails, and the plates are connected by a loose means so that these plates can be opened and closed at the same time.
A pair of cloths provided between the plates are suspended so that they can swing, and a vibrating shaft is arranged along the rails below a support bar on which these cloths are hung. And a vibration device. Then, in order to double the vibration of the cloth, the cloth support bar is inserted into a guide stand standing upright on the back of the plate, and the support bar is rotatably supported by upper and lower springs.

[Action]

The present invention is configured as described above, and after the slag is generated between the plates, when the plates are opened, the load of the slag adhering to the cloth causes the support bar of the cloth to push down the vibration shaft, and the gravity rapidly To fall. Then, the slag attached to a part of the cloth is peeled off by the impact. Next, when the vibration shaft is gradually raised by the elevating device and the vibration device to vibrate, the support bar and the cloth are vibrated and pulled up.
The cloth that is difficult to plate is pulled up to form a flat plate, and the slag easily separates. Further, the cloth is vibrated so that the slag can be separated from the cloth. The vibrating shaft stops when it reaches the uppermost point of the ascent and descent, and then the vibrating shaft descends to a predetermined position to return the cloth to the over position. If the cloth support bar is supported by a spring from above and below to be swingable, the vibration of the cloth can be doubled and the cloth can be automatically returned to the over position.

〔Example〕

The embodiment of the present invention will be described in detail with reference to the drawings. In FIG. 1, reference numeral 1.1 is a front and rear frame, reference numeral 2 is a rail spanned between frames 2.2, and a large number of plates 3 are arranged side by side. ing. These plates 3 ... Are connected by a link chain 4 so that they can be opened and closed at the same time. A cloth 5 is hung from the front and rear of the plate 3, and the cloth 5
The upper end of is suspended from the support bar 6. Support bar 6
Is inserted into a guide stand 7 standing upright on the back of the plate 3, and a spring 8.8 inserted into the guide stand 7 holds the support bar 6 from above and below to support it so that it can swing.
The cloth 5 from which the slag has been peeled off is placed in an excessive position.
A vibrating shaft 9 is arranged below the support bar 6 along the rail 2. At both ends of the vibrating shaft 9, the piston 11 of the suspended air cylinder 10 is
Are connected, and when the piston 11 is expanded and contracted, the vibration shaft 9 moves up and down. Further, a limit switch 12 is provided opposite to the uppermost point of the vibration shaft 9,
When the piston 11 is contracted, the vibration shaft 9 moves up.
When the vibrating shaft 9 comes into contact with the limit switch 12, the working chamber of the air cylinder 10 is opened to the atmosphere, and the vibrating shaft 7 descends to its fully extended state due to its own weight and the gravity of the cylinder in the opposite direction. To do. On the other hand, the weight of the cloth 5 lowers the support bar 6 to the position where the upper and lower springs 8.8 are suspended, and returns to the over position.
Further, a vibrator 13 is provided at one end of the vibrating shaft 9. When the vibrating shaft 13 is operated, the vibrating shaft 9 vibrates, and the support bar in which the lower spring 8 is compressed by the weight of the cloth 5 to which the slag is attached is compressed. Vibration is transmitted from below 6. Then, by contracting the piston 11 of the air cylinder 10 described above, the vibrating shaft 9 becomes the cloth 5
The support bar 6 on which is suspended is pushed up, and the cloth 5 is pulled while vibrating. The cloth 5 is pulled up and the board 4
The uneven surface of the slab becomes a flat plate shape from the rugged surface, the slag is partially separated from the cloth 5, and is separated from the cloth 5 by the vibration of the vibrator 13.
Further, since the support bar 6 is held by the spring 8.8 from above and below, the vibration of the vibrator 13 is doubled and transmitted to the cloth 5. In addition, slag peeling is a cylinder
When the stroke of 10 is not sufficient, the vibration shaft 9 can be pulled up to the uppermost point to give a quick drop operation.

[Effect of device]

The present invention is constructed as described above, and the slag can be separated from the cloth by vibrating the cloth while gradually pushing it up with the vibration shaft. That is, in the conventional device, a large number of plates are opened at the same time, and the cloth is sequentially vibrated from above, so when the cloth bites into the uneven surface of the board, the cloth above the board bends and the entire cloth Vibration is not transmitted and it is difficult to remove the slag, and
Since the cloths are vibrated one by one, it requires a lot of miscellaneous time. However, the invention of the present application vibrates the cloths while gradually pulling them up. Therefore, even if the cloths cut into the uneven surface of the plate, When the cloth is stretched, the uneven upper surface of the cloth becomes a flat plate shape, the slag is partially separated from the cloth, and the slag can be easily separated by applying vibration to the cloth. Moreover, since the dregs attached to the entire cloth can be peeled off all at once, the peeling time is short.
