Description

[Detailed description of the invention] The present invention relates to a flange that is attached to the filter plate of an open-plate filter to form a stock solution passage hole, and particularly to a flange that is suitable for being attached to the filter plate of a two-stage compression filter that uses a filter frame. It provides:

A conventional flange of this kind has a stock solution passage hole 1 as shown in Figure 1.
a. One flange body 1 integrally formed with a protrusion 1b and a passage groove 1C connected to the stock solution passage hole is used by combining it with the other flange body 3 with a filter plate 2 in between, as shown in FIG. It has been known.

When using this, when the filter plates are pressed and the closed plates are aligned, the protrusion 1b will come into contact with the other flange body of the flange attached to the adjacent filter plate,
It is well known that in this state, the stock solution is poured into the filtration chamber through the passage hole 1a and the passage groove 1C, thereby being filtered.

After this primary filtration is completed, the inventor devised a two-stage compression filtration in which the filter plate is further pressurized, the filter frame interposed between the filter plates is compressed, and the filtration chamber is pressed, thereby achieving a strong filtration effect. However, since the conventional flange is made of metal and the protruding part is also made of metal and integrally molded, there is a problem that secondary compression cannot be performed if the adjacent flanges are in contact with each other when the plate is closed after primary compression.

Therefore, the present invention aims to eliminate the above-mentioned drawbacks by molding the abutting protrusion part from an elastic body and to provide a flange having the effects described below. Hereinafter, illustrated embodiments of the present invention will be described.

The flange S of this example shown in FIGS. 3 to 5 consists of a pair of flange bodies Sa and Sb each having a stock solution passage hole 4 and 5 formed therein, and a rib 6.
A filter plate mounting groove 10 is formed by consecutively arranging the tubes 7 and 8 and 9 facing each other.

One flange body Sa has a groove-shaped fitting recess 11. . . . is formed by forming a cut-out flange portion around the flange portion made of metal, and a protrusion 12 made of an elastic material such as rubber is fitted into the recessed portion 11° . . . are doing(
(See Figure 5).

The protruding body 12 has a fitting portion 12a with the concave portion 11 widened into a skirt shape according to the dovetail-like concave portion, and is fitted into the concave portion 11 without being bent.

Due to the protrusion of the protrusions 12, a passage groove 13 communicating with the passage hole 4 is formed between the protrusions.

Further, the pair of flange bodies Sa and Sb are connected by passing a bolt 14 through an insertion hole 6a formed in the center of the rib 6 and screwing it into a screw hole 7a formed in the rib 7.

In the flange S of this example, as shown in FIG. 6, after aligning the ribs 6.7 and abutting the flange bodies Sa and Sb at the mounting holes from both sides of the filter plate, the bolts 14 are inserted into the insertion holes 6a. It is attached to the filter plate K by screwing it through the screw hole 7a.

Then, by pressing the filter plates K with the cylinder and aligning the closed plates, the protruding body 12 comes into contact with the adjacent flange body Sb', and the stock solution is transferred through multiple channels in a state of primary compression with a constant distance between the filter plates. It passes through the passage holes 4 and 5 and the passage groove 13, is press-fitted into the filtration chamber B formed between the filter frame and the filter plate, and is filtered by the filter cloth E.

Then, after a certain period of time has elapsed, the filter plate K is further pressed with a cylinder, so that the protruding body 12 is bent and compressed, so that the filter plate K is moved and the filtration chamber B is further compressed, resulting in rapid filtration. (See Figure 6).

As described above, according to this example, since the protruding body 12 is formed of an elastic body, it can be used by being attached to a filter plate that performs a two-stage compression filtration action, and the main body of the flange other than the protruding body 12 is made of metal. Therefore, it has a solid structure.

Further, since the protruding body 12 is attached by simply fitting the protruding body 12 into the recess 11, it is extremely easy to attach and detach the protruding body, and it does not take much time to replace a damaged protruding body.

In this regard, in the past, since the protruding part was integrally molded, even if only the protruding part was damaged, it was necessary to replace the entire flange, which was wasteful.

Although each embodiment is configured as described above, the present invention is not limited thereto.

For example, the shape of the protruding body does not matter as long as it can be attached to the attachment part of the flange part.

Further, the configuration of the mounting part may be appropriate, and as shown in FIG. The protruding body 17 may be attached by fitting a skirt-like enlarged fitting portion formed at the base of the body 17.

Furthermore, the material of the flange body to which the protruding body is attached or the other flange body may be made of any material, such as metal, rubber, or other plastics.

Note that the configuration for coupling the pair of flange bodies is also suitable, and may be coupled by a conventional screw coupling or by screwing a bolt passed through a filter plate.

In short, the present invention combines a pair of flange bodies each having an undiluted liquid passage hole, and forms a filter plate mounting groove around the periphery thereof, and also forms a protrusion on one flange body to form a passage groove connected to the undiluted liquid passage hole. In the filter plate, the protruding body is made of an elastic material and protrudes from the flange of one of the flange bodies. This is a flange for forming stock solution passage holes in a filter plate applicable to a two-stage compression source, which is characterized by being detachably attached.

Therefore, according to the present invention, since the protruding part that contacts the adjacent flange is an elastic material, it can be used as a filter plate for two-stage compression filtration, and since the protruding part can be freely attached and detached, damaged protruding parts can be replaced. The effect of saving money is significant.
