DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION This invention relates to improvements in Kakehari device filter cloth of the filter press, there is provided cents no device that outside are in use can be easily detachably attached to the filter plate .

[0002]

2. Description of the Related Art As a conventional technique for hanging a filter cloth on a filter plate, there is Japanese Utility Model Laid-Open No. 4-102604, for example. In this apparatus, a filter cloth hanging pin is implanted in a filter cloth hanging rod horizontally extending above a filter plate, and a pin hole provided at an upper end edge of the filter cloth is engaged with the filter cloth hanging pin.

[0003]

However, in the above-described conventional apparatus, it is easy to attach the filter cloth hanging rod inserted through the filter cloth to the filter plate, but the filter cloth hanging rod is inserted through the filter cloth. It is troublesome because there is a filter cloth hanging pin. Further, when the filter cloth is damaged, it is not possible to remove and replace only the filter cloth.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the gist of the invention is that a support bar for suspending a filter cloth is provided above a filter plate of a filter press. And both ends of this support bar in the opening and closing direction of the filter plate
Then, several sets of latches whose upper ends are bent downward in a hook shape are fixed with the bent portions facing each other, and the interval between the opposed bent portions of the pair of latches and the The height of the lower end from the upper surface of the support bar is made larger than the diameter of the cored bar attached to the upper edge of the filter cloth, while a bag is provided at the upper edge of the filter cloth. A portion corresponding to the width of the latch is cut out, and the core inserted through the bag portion is detachable from the latch.

[0005]

The apparatus according to the present invention is constructed as described above. In order to hang the filter cloth on the filter plate, a core metal is inserted into the bag at the upper end of the filter cloth in advance, and the core is inserted into the bag. What is necessary is just to drop gold between the curved parts of a pair of latches from above. By doing so, the core bar engages with the base of the latch, and the filter cloth with the core bar inserted through the bag can hang down to cover one filtration bed of the filter plate. Similarly, the other filtration bed of the filter plate can be covered.

[0006] Thus, braze attached fabric, metal core is supported in engagement with the sets of latches for downwardly and laterally, without outside are the bent portion of the latch is provided above , Supported within the latch. That is, the filter cloth, there is a spring effect upward in vibration or the like to the reaction force and peeling of the cake peeling, in which it is possible to prevent the outer is the bent portion. Also, to remove the filter cloth from the filter plate,
The core metal from the latch is convenient also to simple maintenance, etc. outside Sunomi. Hereinafter, the present invention will be specifically described with reference to the drawings.

[0007]

1 is a schematic side view of a filter press embodying the present invention. Reference numeral 1 denotes a frame, 2 denotes a guide rail bridged between left and right frames, and 3 denotes a guide rail 2.
The top view shows a state in which the filter plates are opened by juxtaposed filter plates, but the detailed configuration of the filter cloth and the like is not shown. Also, reference numeral 4
Are movable heads used to open and close the filter plate 3;
Is a supply pipe for washing water of the filter cloth.

Next, a filter plate 3 and a filter cloth hanging device will be described with reference to FIGS. As shown in FIG. 2, the left and right support arms 3a of the filter plate 3 are engaged with the guide rails 2 so as to be movable on the guide rails 2, and the filter beds 3b before and after the filter plates 3 are arranged as shown in FIG. It is made to be covered with the filter cloth 6.

The structure of the device for hanging the filter cloth 6 on the filter plate 3 will be described. A mast 7 is provided upright on both shoulders of the filter plate 3 as shown in FIG. Between the masts 7.7, a support bar 8 is suspended. As shown in FIG. 4, the support bar 8 is formed of a square pipe, and a latch 9 having an upper end curved in a hook shape on both sides (with reference to FIG. 4) has a curved portion 9 a inside the curved portion 9 a (see FIG. 4). It is fixed so as to form a pair toward the support bar (center side).

As shown in FIG. 3, several pairs of latches 9 are fixed to the support bar along the support bar 8. The interval between the latches 9 forming the pair is an interval through which a core 10 provided on the upper edge of the filter cloth 5 can pass.
The height of the lower end of the bent portion 9 a of the latch 9 from the upper surface of the support bar 8 is also larger than the diameter of the core 10.

On the other hand, the filter cloth 6 is formed in a quadrangular shape so as to cover the filtration bed 3b of the filter plate 3 shown in FIG. 2, and a bag portion 6a is formed at an upper end edge thereof. A portion of the portion 6a corresponding to the width of the latch 9 fixed to the support bar 8 is cut out, and the bag portion 6a does not interfere with the latch 9 when the core bar 10 inserted into the bag portion 6a is engaged with the latch 9. Like that. In addition, a supply plate 11 for supplying the undiluted solution is attached to the upper center, and a core bar 12 is attached to a bag at the lower edge of the supply plate 11 so as to hang down.

The apparatus according to the present invention is configured as described above. In order to hang the filter cloth 6 on the filter plate 3, the core bar 10 inserted into the upper bag portion 6 a is hooked on the support bar 8. 9 can be hung by a simple operation of dropping from above and engaging. That is, the core metal 1 dropped into the latch 9
0 is the weight of the filter cloth 6, the liquid supply plate 11, and the lower metal core 12;
It can be fixed by hooking on the base of the latch 9 by being pulled by such weight.

The filter cloth 6 fixed in this manner is
Tensioned by its own weight and the weight of the liquid supply plate 11, etc.
The wrinkles do not wrinkle even when the opening and closing are performed, and the cored bar does not fall off in the latch 9 even if it is vibrated to peel off the attached cake.

[0014] In addition, to remove the cloth 6 braze and Kakehari In this way, a simple outside Sunomi the metal core 10 from the latch 9, is convenient to exchange and maintenance, to check in Kakehari state Since there is no obstacle above, the workability is good.

[0015]

As described above, the hanging device for the filter cloth according to the present invention can be easily attached to and detached from the filter plate, and the hung filter cloth can be tightened and wrinkled during use. it no to such outer be, is obtained by solving all the problems of conventional Kakehari apparatus of this kind filter cloth.
