Description

[Detailed Description of the Invention] This invention relates to a P cloth changing device that does not require any driving device to change the F cloth of a belt press.

A belt press is used as a dewatering device for the sludge generated at the sludge treatment facility.

This belt press dewaters the slurry by compressing it between a pair of endless belt-shaped cloth, but the plastic cloth gets tired and wears out with use, so it is essential to replace it after using it for a certain period of time. there were.

This invention allows the above-mentioned P cloth replacement to be easily performed, and in particular, when replacing the old furnace cloth, it is possible to replace the old furnace cloth by using the rotation of the new F valve shaft for replacement, without requiring a drive device. An object of the present invention is to provide a P cloth changing device for a belt press that rotates the winding shaft of the belt press and smoothly changes the cloth.

An embodiment of this invention will be described below with reference to the drawings.

As shown in the schematic diagram of FIG. 1, a belt press dewatering device to which this invention is applied has rollers 1 to 6, high pressure rollers 7, rollers 8 to 10, furnace cloth cleaning device 11, etc. meandering in the direction of arrow A. An endless belt-like lower door cloth 12 and rollers 2 to
6. An endless belt-shaped upper part p that snakes in the direction of the arrow including the high-pressure roller 7, rollers 8, 13 to 16, p cloth cleaning device 17, etc.
A pressure belt 20 supported by pressure rollers 19, 19, 19 is disposed outside the high pressure roller 7, and the upper and lower F fabrics 12 and 18 are moved toward the high pressure roller 7. There is a lot of pressure on people.

And these upper and lower F cloths 12 and 18,
Pressure belt 20, roller 1. ...19, The wave cloth cleaning devices 11 and 17 are all belt press frames 21
The frame 21 is supported by the frame 21 shown in FIGS.
As shown in the figure, the F cloth support mechanism 22 supports the replaced cloth.
is provided.

The furnace cloth support mechanism 22 may have any structure as long as it can rotatably and removably support the new and old replacement F shafts 23 and 24 as shown in FIGS. 4 and 5, but for example, As shown in FIGS. 6 and 7, a belt pulley 26 is provided at the tip of a shaft 25 that passes through a hollow replacement door valve shaft 23, 24, and a nail 2 is attached via a fixing member 27.
If the structure is such that the new and old valve shafts 23 and 24 are fixed with 8 etc., simply insert and set the new and old valve shafts 23 and 24 while lifting one end of the shaft 25 upwards. and 24 can be supported.

And, between the new and old F shafts 23 and 24 for replacement, a
As shown in Figures 3 and 4, for example, a rubber belt,
An inter-shaft transmission means 29 consisting of ropes, chains, etc., is provided to transmit power between them.

The inter-shaft transmission means shown in FIG.
A rubber belt 29 is disposed thereon so that power from the new furnace valve shaft 23 can be transmitted to the restoration valve shaft 24.

Next, the furnace cloth replacement operation of this invention will be explained.

First, when replacing the upper furnace cloth 18, as shown in FIG. A restoring valve shaft 24 for winding up the old furnace cloth to be replaced (the furnace cloth currently wound around a roller) is supported below the furnace cloth support mechanism 22.

Furthermore, both F valve shafts 23 and 24 are connected by an intershaft transmission means 29.

Then, the connected portion of the old furnace cloth 18 that is currently being wound is positioned near the roller 8 and stopped.

Next, the connecting portion 30 of the old P cloth 18 to be replaced is removed, and one end of the new furnace cloth 18' is connected to one end of the upper furnace cloth 18 that was previously removed.

On the other hand, the other end t of the old furnace cloth 18 to be replaced is joined to the old furnace valve shaft 24 for winding up the old cloth using a chuck or the like.

After that, when the furnace cloth of the belt press is run, the new furnace cloth 18' is tensed as it runs, and moreover, the inter-shaft transmission means 2
Since the restoring valve shaft 24 rotates via the valve 9, the old furnace cloth 18
automatically performs the winding operation.

Therefore, when replacing the old furnace cloth 18, a winding drive device is not required.

After the old furnace cloth 18 is wound around the old valve shaft 24,
Both ends L' and l of the new furnace cloth 18' are connected to complete the furnace cloth exchange.

In addition, in the case of replacing the lower furnace cloth 12, the new furnace valve shaft 23 wrapped with a new replacement furnace cloth 12' is attached to the furnace cloth support mechanism 22.
The old-style valve shaft 24 is supported below and above, respectively, and the furnace cloth is replaced in the same manner as described above.

The one shown in FIG. 8 is another embodiment, in which the old and new furnace cloth shafts 23.
As the power transmission means 29 of 24, a rubber roller pressed against the outer peripheral surface of the old and new furnace cloth is employed.

According to this example, the rotation speed of the old p-valve shaft corresponds to the moving speed of the new cloth, so that the old cloth can be smoothly wound up.

As described above, according to the oven cloth changing device of this invention,
The belt press frame is equipped with a furnace cloth support mechanism that supports the replacement cloth, making it extremely easy to replace the furnace cloth.Moreover, the shafts of the new and old replacement furnace cloths are connected, and the shafts that transmit power are connected to each other. Since the transmission means is provided, there are extremely excellent practical effects such as being able to wind up old furnace cloth without the need for a dedicated drive device.
