Description

[Detailed description of the invention] This invention relates to a cloth hanging device for a filter press that has an extremely wide adjustment range for the expansion and contraction of the cloth. The present invention proposes a fabric hanging device that is highly effective for use in so-called single fabric traveling type filter presses.

Traditionally, the cloth used in filter presses expands and contracts significantly when it is dry and wet, and when it is new and when it is clogged. In particular, when clogged, the shrinkage can be as much as 3% or more, and for example, in the case of 2m of cloth, it will shrink by 60mm or more. For this reason, in conventional machines, in order to cope with the shrinkage of the cloth, an adjustment screw is attached to the drive chain, and one end of the cloth is wound up with a torsion bar, but these methods are effective in the case of sludge that easily clogs. The adjustment limit is quickly exceeded, causing problems such as the fabric becoming abnormally tense and the fabric support bar bending. This idea was made in view of the actual situation, and it is possible to use a guide roll wrapped around the lower end of the cloth to constantly bias the cloth in the direction of pulling it, and furthermore, to impair the driving function of the cloth. We have realized a device that can be adjusted over a wide range in response to the expansion and contraction of the cloth.

Below, this invention will be explained in detail based on the attached drawings.The structure consists of a large number of horizontally arranged plates 1...
Driving device 3... in which cloth 2... is suspended so as to form a character shape, and its upper end is provided above plate row 1...
The lower end of one of the cloths 2a is connected to the plate 1.
After winding the guide roll 4 provided at the bottom of the board 1, pass through the bottom of the board 1 to connect the adjacent boards 1, 1.
is connected to the lower end of the other cloth 2b provided in the same manner as above, and furthermore, these connected cloths 2a, 2b
In the cloth hanging device connected to the drive device 3, both ends of the guide roll 4 are inserted and supported through the long holes 6 of the support rod 5 hanging from the lower part of the plate 1, and the guide roll 4 is , the cloth 2 is always biased in the pulling direction. To describe the biasing device for the guide roll 4 in more detail, the second
In the figures and FIG. 3, reference numeral 7 denotes an elastic string-like body made of a spring or rubber, etc., which is connected to support pins 8 provided at both ends of the pair of guide rolls 4, respectively. A protrusion 9 provided on the support rod 5 is hung below the mounting position. Note that 10 is a sleeve for preventing the support pin 8 from coming off.

Next, the hanging state of the cloth 2 will be explained based on FIG. The lower edge of each of the cloths 2a, 2b of the adjacent panels 1, 1
and is connected to the lower support bar 12.

Then, the upper support bar 11 and the lower support bar 12
are connected to both ends of a drive chain 13 wound around a drive device 3 provided at the top of the plate 1, and by rotating the drive device 3 forward and backward, the upper support bar 11 and the lower support bar 12 are moved in a seesaw shape. It is designed to go up and down. That is, when discharging the cake, lower the pair of cloths 2a and 2b,
The cake is peeled off by making a U-turn around the guide rolls 4, 4. Note that 14 is a liquid supply plate.

The device according to this invention is constructed as described above, and when the cloth becomes clogged and shrinks, the guide roll 4 around which the cloth 2 is wound slides upward to relieve the excessive tension. can do. That is, in the conventional device, abnormal tension in the cloth 2 was alleviated by stopping the operation and lengthening the chain 13 for traveling the cloth. However, in the fabric hanging device of this invention, even if the fabric shrinks, the elastic string-like body 7 is wrapped around the protrusion 9 and its both ends are connected to the guide roll 4. Since the guide roller 4 slides upward until the tension of the cloth 2 is automatically extended and the tension of the cloth 2 becomes normal, the support bars 11 and 12 will not be bent and the drive device 3 will not be damaged. Since this does not occur, there is no problem in driving the cloth 2. In addition, if the protrusion 9 on which the elastic string-like body 7 is wound is rotatably provided, the tension of the cloth 2 can be adjusted on average even if the degree of stretch of each cloth 2 is different. It is.

As described above, although the cloth hanging device of this invention is a simple device, it does not require the time and effort of stopping operation to relieve abnormal tension in the cloth, unlike conventional devices. It is possible to automatically adjust the fabric, and is very effective when used with large machines where the fabric has a large degree of expansion and contraction.
