CONSTITUTION:The hanging spring 18 of the hanging supporting member for filter cloth 21 is hung to the guide rail 15 disposed in the direction of the filter plate arrangement, and the filter cloth 21 is hung down between the filter plates 13 by the hanging spring 18. On the other hand, a sending plate 20 is projected from the outer periphery to the moving passage of the hanging spring 18, and a chain 24 as a positioning member for the hanging spring 18 is installed between the sending plate 20 and the hanging spring 18. ln this state, each filter plate 13 is moved one by one by a filter plate sending unit 27 to be separated to the side of a movable plate 28 to hang the filter cloth 21 in a chevron shape between the filter plates 13 so that cake is dropped down from the filter cloth 21. At this time, the hanging spring 18 is moved to the terminal end of separation distance without an inadequate elongation between the sending plate 20 of the filter plate 13 and the chain 24.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a hanging device for hanging a member of a filter press from a guide rail to between filter plates, and allows the cake to fall when the filter plates are separated.

2. Description of the Related Art Conventionally, as shown in FIG. 5, for example, support plates 2 are provided on both sides of a filter plate 1, links 3 are attached to the support plates 2, and the links 3 are connected by a P-shaped rod 4 to connect adjacent filters. The furnace cloth 5 of the plate 1 is hooked on the P-shaped rod 4 and its upper end is supported by the furnace cloth hanging rod 6. A rail is provided above the filter plate group to support the roller group, and a spring 9 is attached to each roller frame 8. There is a well-known cake shaking device for a filter press that suspends the P cloth hanger 6 using these springs and shakes off the cake from the oven cloth 5 by opening a space between the door plates.

Problems to be Solved by the Invention In the above-mentioned cake shake-off device, when the door plate starts to be fed, the spring is pulled diagonally by the furnace cloth on the door plate side, and the roller at the upper end of the spring tries to slide. However, at this time, the door plate has already passed halfway through its separation distance, and the spring is greatly stretched. When the door plate reaches the end of its separation, the spring is stretched further from the rail and swings sharply with the rollers. At this time, the oven cloth adjacent to the oven cloth separated from the other tries to pull back the stretched spring in the opposite direction. For this reason, the spring expands and contracts in a complicated manner and considerably, and as this process is repeated, the spring may stretch beyond its elastic limit. Also, place the hearth cloth rod on the hearth cloth above the door plate,
Even if you open the furnace cloth by tilting it steeply along the door plate to make it easier for the cake to fall from the furnace cloth, if the sticky cake strongly adheres to both P cloths that enclose it, both P.
The force of trying to open the cloth and the fairly large stretching action on the spring combine to make the spring thicker (
It stretches it out.

Therefore, an object of the present invention is to prevent the springs from being inadvertently stretched to their full extent in the conventional method when separating the door panels by feeding the door panels one by one or by simultaneously opening the door panels, thereby safely ensuring that the springs hung from the rails are fully extended. An object of the present invention is to provide a hanging device for a P material in a filter press that moves the P material to a separated filter plate side.

A means for solving the problem, that is, the present invention, is to movably suspend the P material between the door panels from a guide rail installed in the direction in which the door panels are arranged, and after filtration, separate the panels and drop the cake from the P material. In the hanging device for P material in a filter press, the P material hanging member hangs one end of the P material from the guide rail and suspends the P material from the other end, and the movement of the P material from the outer periphery of the door plate. The device includes a protruding body that protrudes from the path, and a positioning member that is interposed between the suspending member and the protruding body and moves the suspending member to a predetermined position within a separation distance by separating the door plate.

Effect of the Invention A hanging member made of P material is movably hung on a guide rail installed in the door panel arrangement direction, and while the P material is suspended between the door panels by the hanging member, the door panel is placed along the moving path of the hanging member. A projecting body is provided protruding from the outer periphery, and a positioning member for the suspending member is interposed between the projecting body and the suspending member, and the door panels are separated and the suspending member is positioned at a predetermined distance. position, and then the hanging member is sent to the distant door plate side by a protrusion belonging to the door plate being sent.

EXAMPLES The present invention will be explained in detail with reference to the drawings. In Fig. 1.2, a plurality of filter plates 13.13 are arranged with their handles 14.14 placed on both side plates 12.12 connecting the two machine frames 10.11 of the filter press, and both machine frames 10.11 are arranged. At the upper ends of the frames 10, 11 there are two guide rails 15. parallel to the sides i2, 12.

Furnace cloth hanging rods 19 are hung parallel to the connecting rods 16 at both lower ends thereof. Further, the tips of the feed plates 20 and 20, whose base ends are attached to both ears provided on both shoulders of the door plate 13, protrude along the moving path of the connecting rod 16 and the suspension spring 18. 21 indicates a furnace cloth, the upper part of which is hung on the furnace cloth hanging rod 19 and attached to the door plate 13.
It is suspended in between. On the left side of FIG. 1, the furnace cloth 21 is shown being tightened between the door plates 13, and on the right side of the same figure,
The door plates are spaced apart one by one and F-1, 21 between the door plates shows a state in which the door panels are hung almost in a chevron shape. 22 is a tightening device for tightening or separating the door plate 13.

Reference numeral 24 indicates a chain as a positioning member that positions the hanging spring 18 at a predetermined position within a separation distance. That is, a hooking hole 25 is formed at one end of the operating portion 23 formed by enlarging the tip of the feed plate 20, and a hooking ring 26 is fitted in the connecting rod 16.
One end of the chain 24 is inserted into the locking hole 25 and fixed, and the other end is connected to the locking ring 26. Instead of the chain 24,
Strings or link pieces of a certain length may be connected in a flexible manner, or a spring having a certain length and elasticity may be interposed. In this case, both ends of the spring are connected to the acting part 23 and the connecting rod 1.
6 or fixedly installed by providing an appropriate seat on the feed plate and the connecting rod.

Further, if a short and small air piston type one is inserted in place of the chain 24, the stroke between the feed plate 20 and the connecting rod 16 can be finely adjusted. Further, when using the above-mentioned string, it is possible to make fine adjustments more easily by wrapping it around one side for the required length. If the spring type or piston type is inserted on the side opposite to the concave chain 24, the connecting rod 16 can be pushed out and positioned at a predetermined distance apart from the filter plate. In this case, the spring or piston is connected to the feed plate 2o of the filter plate which is then separated from the connecting rod 16.
It is compressed between As mentioned above, the hanging spring 18 or the furnace cloth hanging rod 19 is usually moved to a position approximately in the middle of the separation distance, but it is not necessarily in the middle, and depending on the separation distance, it may be stably positioned at a position slightly shifted to the left or right. Good too. next,
When the hanging spring 18 or the connecting rod 16 is fed to the end of the separation distance by the feeding plate 20 of the separating filter plate, the chain 2

In the above description, the connecting rod 16 is not necessarily necessary and is omitted, and the upper end of the hanging spring 18 as a hanging member is connected via another slide or the like. - It may be configured to be movably supported on the wheel 15.

Further, the feed plate 20 is a projecting body that protrudes from one or more appropriate positions on the outer periphery of the filter plate, and has an arbitrary shape such as a plate shape or a rod shape. Therefore, the feed plate 20 is not limited to the one on the concave side, but screws or small pieces having each crosspiece width may be attached to appropriate locations, and the suspension member or the connecting rod may be fed using these. Further, the feeding member 20 may be made to be able to expand and contract in the vertical direction and may be brought into contact with a hanging member or a connecting rod.

After filtration, a known p-board guide device 27 is used in the filter plate separation operation.
The filter plates 13 are separated one by one toward the movable plate 28, and the oven cloth 21 is suspended between the filter plates 13 in a substantially chevron shape, and the cake is allowed to fall from the oven cloth. At this time, the hanging spring is smoothly pulled out in the separating direction by the feed plate 20 of the separating filter plate from the beginning of separating the filter plates, and the separating filter plate reaches the end of separation and is moved approximately to the middle thereof. Before and after the cake falls, the hanging spring 18 is not forcibly stretched from the rail 15 or from the oven cloth 21 between the filter plates. Feed plate 2 for filter plates that are successively separated
0, each suspension spring is sent to the end of the separation distance, and the furnace cloth 21 suspended from the suspension spring is aligned and superimposed on the already spaced filter plate.

Also, in Figures 1 and 2, numbers 29, 29ai'! ?
F This is a device for preventing the hanging member from falling, which is composed of a hanging spring 18 stretched close to the lower side of the cloth hanging rope 19. The drop prevention device includes a wire rod and a receiver 29a installed on the feed plate 20 below the wire rod.
Both ends of the wire rod are attached to the machine frames 10 and 11 via tensioning devices. Further, the fall prevention device may be one in which a link or a string-like body is provided along the capacitive spring 18, respectively. By providing the above-mentioned fall prevention device, if the hanging member is unexpectedly stretched unexpectedly, the receiver will stop this and avoid the danger. Also,
Temporarily hang the furnace cloth hanging rod on the fall prevention device,
Attaching the hanging member facilitates the work of removing sushi. Further, even when replacing the furnace cloth, the work efficiency is facilitated without unnecessarily expanding or contracting the hanging member.

Further, in FIGS. 1 and 2, reference numeral 30 is a rod for drawing the furnace cloths 21, 21 suspended in a substantially chevron-shaped manner between the separated filter plates further toward the filter plates and increasing the inclination thereof.

31. 31 is a connecting piece of the rod 30, and the feed plate 20.
One end of each rod 30 is swingably fixed in the middle of the rod 20, and both ends of the rod 30 are connected between the other ends. These connecting pieces 3
1.31 are made to have different lengths so that they do not come into contact with each other when the filter plates are tightened. As mentioned above, increasing the inclination of the furnace cloth will cause the furnace cloth to shrink by that amount. However, the hanging member can be moved without difficulty.

Next, in the example shown in Fig. 3.4, the tightening device 22 is driven to separate the filter plates simultaneously and the cake is dropped, and the tightening device 22 is reversely driven to separate the cakes between the separated filter plates. will be closed at the same time. In the figure, reference numeral 32 is a connecting tool for connecting and separating the handle portions 14 of each filter plate 13 from each other. In this example, the same parts as in the example of FIG. 1.2 are given the same reference numbers and the explanation will be omitted.

The left side of the figure shows a state in which the filter plates are closed, and the right side shows a state in which the filter plates are separated all at once. In the filter plate separation operation, the suspension springs are smoothly pulled out in the separation direction from the beginning of the filter plate separation by the feed plates belonging to the filter plates to be separated, and are moved to the middle of the separation distance. Each oven cloth is suspended in a substantially chevron-shaped manner between each filter plate to allow the cake to fall. Next, when each filter plate is simultaneously moved in the closing direction by the tightening device, the feed plate 20 belonging to each filter plate sends each suspension spring to its original position in the opposite direction to the previous case, and the P cloth is again aligned with the separated filter plate and polymerized.

In the above description, the filter plate may be a normal filter plate or a P frame body, or may be a compressed type filter plate provided with a compressed membrane, and its shape may also be square or round. In addition to the method described above, the filter plates may be spaced apart by providing movable plates on both sides of the rows of filter plates to be spaced apart. Alternatively, the filter plate array may be divided into several sections, and the filter plates may be separated from each other in each section.

Effects of the Invention According to the present invention, when separating the filter plates by feeding one filter plate or by simultaneously opening the filter plates, the suspension member of the member moves smoothly from the beginning when the filter plates are separated. The FR is then suspended between the filter plates at a predetermined position separated by a distance, and then safely sent to the side of the separated filter plate by the fed filter plate. Further, the hanging member is not stretched, and the cake can be dropped by stably hanging the member between the filter plates.
