Description

[Detailed description of the invention] This invention is based on the filtering of the front and rear filter plates, respectively, in the gap between the filter plates 1 and 1, which are connected by a simultaneous opening/closing mechanism (not shown), as shown in FIG. Cloth support floor surface 1a.

The upper edges of each pair of filter cloths 2 a and 2 b covering the filter plates 1 b are attached to one filter cloth support bar 3 temporarily positioned above the filter plates, and
The lower edges of each pair of filter cloths 2a, 2b covering the front and rear filter cloth support surfaces 1a, 1b of each filter plate, respectively, are connected to a pair of guide rollers 4 disposed below the filter plate 1. , 5, each lever is turned in the direction in which the two approaches, and then
It is attached to a single filter cloth support bar 6 temporarily positioned below the filter plate, and a flexible string-like driving medium (chain 7) is attached to both ends of each of the filter cloth support bars 3 and 6. A string-like driving medium (chain 7) connected to the upper and lower filter cloth support bars 3 and 6 is connected to a string-like driving medium drive device (sprocket wheel 8) provided on the upper part of the filter plate 1. )
When driven by the filter cloth support bars 3 located above and below,
6 move in opposite directions in a seesaw manner, and each filter cloth 2a,
This invention relates to a filter cloth unit for providing a filter press configured such that the filter cloths 2b can all make a U-turn and reciprocate around the guide rollers 4 and 5 below the filter plate 1.

In FIG. 1, reference numeral 9 indicates a stock solution supply passage formed through the filter plate 1, and 10 indicates a lower part of the filter cloth support bar 3.
The filter cloth 2a is positioned between the pair of filter cloths 2a and 2b,
2b is a liquid supply plate having a T-shaped stock liquid passage 10a.

In the filter press as described above, the filter cloth 2 a
, 2b are consumables, so they need to be replaced once every few months or once every six months. In a filter press in which a traveling filter cloth device is constructed of filter cloths 2a and 2b, if a portion of the filter cloth is damaged, only the damaged portion of the filter cloths 2a and 2b needs to be replaced. However, this invention aims to standardize the filter cloth and provide it at a low cost so that the filter cloth can be replaced extremely easily and quickly in the above-mentioned cases. The gist of this is a pair of filter cloths that are suspended around a guide roller at the bottom of the filter plate, and whose ends are connected to a filter cloth running drive device provided at the top of the filter plate. This unit is made by folding a rectangular filter cloth in half from the center, sewing the folded edges at a certain width position, and forming a bag part for inserting a filter cloth support bar into the folded part. In addition, bag portions for inserting filter cloth support bars are formed on both end edges of the filter cloth, and lacing joint portions are formed by alternately cutting out the bag portions on both end edges. and the length between the bent portion and both ends of the filter cloth forming the pair of lacing joints is equal, and the plurality of filter cloth units are connected to the lacing joints. A filter cloth unit for a filter press, characterized in that when connected in series at the parts, the side surface shape becomes a series of continuous W-shapes, and each curved part of the filter cloth unit can be rotated to the guide roller. It is in.

One embodiment will be explained in accordance with the manufacturing order with reference to FIG. , folded in half along the central bending line a in the length direction (Figs. 3 and 4), and then stitched 13 at a position a certain width α from the bent edge 12, which will be described later. The bag portion 14 for inserting the filter cloth support bar 27 is formed, and the filter cloth A
A part of the edge is bent along the bending line C, and stitches 17 and 18 are made at positions of a certain width α from the bent edge 15 and 16, respectively. Bag portions 19 and 20 for inserting a filter cloth support bar 29, which will be described later, are formed on the end edges, respectively.
Cut out the notches 21 of both sides alternately to the appropriate width.
One notch 21, 21 by ゜21...
The remaining portions of the other bag portion 20 fit into the other bag portions 20, respectively, and the remaining portions of the one bag portion 19 fit into the other notch portions 22, 22, .
Both lacing joints 23 . . . are formed with lacing joints 23 .
24 and the bag portion 14 on the side of the bent edge 12 which can be folded in half, the lengths 1 a and 1 b are configured to be equal lengths.

In the figure, reference numeral 25 indicates a through hole for the stock solution, which is formed at the mounting position of the liquid supply plate 10, and 26 and 26, which are located on the inner side of the filter cloth A that is bent in two, and which are connected to the liquid supply plate 10. This is a patch sewn onto filter cloth A to cover the lower edge of the filter.

The filter cloth unit 11 of this invention is configured as described above, and when a plurality of filter cloth units 11 are connected as follows, the side surface shape becomes a series of continuous W-shapes, and each filter The curved portions of the cloths 2a and 2b are passed around the guide rollers 4 and 5 at the bottom of each filter plate 1, respectively, and each of the filter cloths 2a and 2b is
, 2b can be connected to a seesaw-like traveling drive device for filter cloth provided on the upper part of the filter plate 1, respectively.

That is, this filter cloth unit 11 has the bag portion 14
Holes 28, 28 at both ends as shown in Figure 5.
After inserting a plate-shaped filter cloth support bar 27 having a filter cloth support bar 27, a pair of chains 7.7 and 7 end tie clamps 30. 30 and the adjacent filter cloth unit 11
After fitting the lacing parts 23 and 24 together,
A filter fabric support bar 29 similar to the filter fabric support bar 27 shown in FIG. If the filter cloth support bar 29 is connected by a support bar 29, and both ends of the filter cloth support bar 29 are fastened to tie clamps 31.31 at the other ends of a pair of chains 7.7, which are suspended from drive sprocket wheels 8, 8. (FIG. 6), it is now possible to easily obtain a series of filter fabric devices for filter presses such as those described at the beginning of this specification.

Therefore, according to this invention, the following effects can also be achieved.

In other words, in the filter cloth unit of this invention, the filter cloth support bar can be simply inserted and removed into the bag portions for inserting the filter cloth support bar, which are formed on the folded edge and both end edges of the filter cloth unit. Since the filter cloth can be installed and replaced with simple operations, the installation and replacement are extremely easy and can be done quickly.

Furthermore, since the filter cloth unit of this invention has the above-mentioned configuration, it is symmetrical, and the length from the bent part to both ends is particularly equal. , one filter cloth support bed 1a or 1 between the filter cloths on either side.
It may be installed so that it faces b.

Therefore, in this respect as well, the filter cloth unit of this invention is extremely easy to attach to a filter press.

Furthermore, since the filter cloth unit of this invention can be manufactured to the same standard, it is suitable for mass production, and the filter cloth as a consumable item can be replaced at low cost.
