[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a filter cloth suspension device for a filter press, and proposes a device for easily attaching and detaching the filter cloth to and from the machine body between narrow filter plates.

[0002]

2. Description of the Related Art An example of this type of filter cloth suspension device is shown in FIGS.
There is something like the one shown in the figure. In the device shown in the figure, an integral filter cloth provided between filter plates is joined via an upper support bar and the upper support bar is supported by a chain wound around a drive wheel. After the lower end of the filter plate is wound around a roll, the lower support bar is attached to the lower end of a filter cloth similarly provided between adjacent filter plates, and the lower support bar is connected to the chain. Is connected to the other end of.

[0003]

However, in the above-mentioned conventional apparatus, it is easy to support the upper edge of the filter cloth when suspending the filter cloth, but it is difficult to support the lower edge of the filter cloth. That is, after supporting the upper edge, the lower end of the hanging filter cloth must be wound around a roll provided at the lower part of the filter plate, and the filter cloth similarly provided between adjacent filter plates must be connected. It is extremely difficult to work between narrow filter plates.

[0004]

This invention solves the above-mentioned problems, and the gist of the invention is that a plurality of filter plates arranged movably on a guide rail are arranged independently of each other. Then, in a filter press provided with a filter cloth that moves up and down, the upper edge of a pair of filter cloths provided so as to cover the filtering surfaces of the left and right filter plates is fixed to the upper support bar,
The upper support bar is supported by a chain wound around a sprocket provided on the mast of the filter plate, and lower support bars are attached to the lower end edges of the pair of filter cloths, respectively, and one of the pair of filter cloths is attached to the filter plate. Is wound around one of a pair of rolls provided at the lower part of the pair of rolls and then positioned between the adjacent filter plates, while the lower end of one of the pair of filter cloths provided between the adjacent filter plates is attached to the pair of rolls. On the other hand, the lower support bar attached to the lower end of the same and the lower support bar provided on the lower end edge of the filter cloth have the suspension bolts connected to the other end of the chain inserted and fixed. is there.

Further, the lower support bar of the filter cloth uses a pipe for the purpose of maintaining light weight and strength in operation.

[0006]

The suspending device according to the present invention is constructed as described above. To suspend the filter cloth, both ends of the upper support bar fixed to the upper edge of the filter cloth are wrapped around the sprockets. supporting the chain and the pendent braze cloth on the Wa wound into a roll provided at the bottom of the filter plate, adjacent filter plates to be positioned above the chain to the lower support bar provided on the lower edge While the suspension bolt provided at the other end of the roll is inserted, one of the pair of filter cloths similarly provided between the adjacent filter plates is wound around the other of the pair of rolls and then provided at the lower end edge thereof. The hanging bolt may be inserted through the lower support bar. This operation
This is extremely easy as compared with the conventional method in which the lower support bar is inserted into the bag portion at the lower edge of the two filter cloths between the narrow filter plates to connect these filter cloths.

By doing so, the upper edge portions of the pair of filter cloths provided between the filter plates are joined together through the upper support bars, and the lower edge portions of the respective filter cloths are adjacent to each other. The lower edge of the filter cloth provided between the filter plates is joined and connected by the lower support bar and the suspension bolt, and the upper support bar and the lower support bar are connected by a chain, and the upper support bar is driven by driving the chain. The lower support bar moves like a seesaw, and the filter cloth connected to it can be moved up and down. Hereinafter, the invention will be specifically described with reference to the drawings.

[0008]

FIG. 1 is a schematic side view of a filter press equipped with a filter cloth suspension device according to the present invention. A guide rail 2 is bridged to left and right frames 1 and 1, and the guide rail 2 is attached to the guide rail 2. A large number of filter plates 3 are movably mounted. Each filter plate 3 is loosely connected by a link chain 4,
The chain 5 for opening and closing is arranged to open and close at the same time in an accordion shape with the central portion of the filter plate group as a boundary. Reference numeral 6 denotes a tightening hydraulic cylinder provided on the movable head 7.

The tensioning device for the filter cloth according to the present invention is provided between the filter plates of the filter press as described above, and its concrete structure will be described with reference to FIGS. 2 to 4. The cloth 8 is obtained by folding an original fabric cut in a rectangular shape into two and providing a bag portion 9 for inserting a support bar at the upper and lower edges thereof, and suspending them between filter plates as shown in FIG. ing. That is, by inserting the upper support bar 10 into the bag portion 9 at the upper edge,
Both ends thereof are supported by a chain 12 wound around a mast sprocket 11 of a filter plate 3, and a lower support bar 13 is inserted into a bag portion 9 at a lower edge portion as shown in FIG. 3 is wound around one of the pair of return rolls 14, 14 provided at the bottom of the chain 3, and is supported by the hanging bolt 15 provided at the other end of the chain 12 at the same time, and is overlapped with the lower support bar 13. , One of the pair of filter cloths 8 between adjacent filter plates is wound around the other of the pair of return rolls 14, 14 and the lower support bar 13 thereof is attached. Reference numeral 16 is a nut for fixing.

That is, in the device according to the present invention, the support bars provided at the upper and lower edge portions of the filter cloth 8 are connected to the chain 12, and by driving the chain 12, the upper and lower support bars are formed into a seesaw shape. It moves up and down, and the filter cloth 8 supported by this runs up and down.

This invention is constructed as described above,
To suspend the filter cloth 8 between the filter plates, the upper support bar 10 inserted into the upper edge of the filter cloth is supported by the chain 12, and then the pair of hanging filter cloths 8 and 8 is attached to the lower part of the filter plate 3. After being wound around the pair of rolls 14 provided, the hanging bolt 15 provided at the other end of the chain 12 may be inserted into the lower support bar 13 inserted at the lower end thereof in a skewered shape.

This suspension operation is compared with the conventional method of inserting a lower support bar into a bag portion of a pair of filter cloths and connecting and supporting the lower support bar to the lower support bar 13 on the side of the filter plate row. It suffices to insert and fix the suspension bolts 15, and the lower support bar 13 can be manufactured at low cost because it is only necessary to make a through hole for inserting the suspension bolts 15 in a rod material such as a pipe. If the threaded portion of the bolt 15 is made long, it is possible to easily adjust the tension when the bolt 15 contracts during use.

[0013]

As described above, the device according to the present invention makes it possible to attach the filter cloth very easily in the filter cloth traveling type filter press, and also the structure of the support portion of the filter cloth is simple and inexpensive. The benefits that can be made and the benefits of using a filter press are enormous.
