Description

[Detailed explanation of the idea] This invention relates to an improvement of the r-plate of a filter press.

Conventionally, most of the P plates of filter presses are made of metal such as cast iron because of the need for strength.

However, since metal items are heavy, large-scale machines require strong foundations and frames to support the planks, and special equipment lacks corrosion resistance. There are other difficulties.

Recently, lightweight p-boards made of synthetic resin have been proposed as an alternative to this, but none of them with diaphragms for use in high-pressure filtration are satisfactory.

In other words, diaphragms with resin adhesives and mechanically screwed diaphragms have been proposed, but both have the disadvantage that the adhesive and mounting parts lack resin strength and are expensive to manufacture. be.

The purpose of this invention is to achieve a complete seal and to eliminate the attachment part that requires strength when attaching the diaphragm to the core plate, and it has solved the above-mentioned conventional difficulties. Hereinafter, this invention will be explained in detail with reference to the attached drawings. First, as shown in the figure, the structure is as follows: a series of grooves 3 for inserting sealing materials 2, 2, respectively;
3, and diaphragms 4, 4 made of synthetic resin are bonded to the front and back sides of the core plate 1, respectively, and a series of grooves 5,
5, fit the sealing materials 2, 2 inserted into the grooves 3, 3 of the core plate 1, and then attach the front and back diaphragms 4, 4 to the upper and lower outer peripheral surfaces of the core plate 1 with countersunk bolts 6! '').

The one shown in the figure uses polypropylene for both the core plate 1 and diaphragms 4, 4 as synthetic resin materials, and
Although a seal material made of rubber is used, if corrosion resistance is particularly required, a material made of soft vinyl chloride may also be used.

Further, FIG. 2 shows a cross-section of the high-pressure fluid supply part to the diacrums 4, 4, and reference numeral 7 shows the passage thereof. FIG. Show the passage.

The device according to this invention is configured as described above,
If the core plate 1 made of resin and the diaphragms 4, 4 are configured separately to facilitate manufacturing, but if they are joined together to configure an R plate with a diaphragm, the concave groove 3 provided in both
, 5, a series of sealing materials 2, 2 are inserted into the diaphragm-attached R-plate which has sufficient pressure tightness to withstand the injection of high-pressure fluid.

When assembling, the diaphragms 4, 4 and the wide plate are not directly connected, but the left and right diaphragms 4, 4 are connected on the outer peripheral surface of the core plate 1. This eliminates mounting parts such as screw taps that require strength.

Conventionally, when attaching a diaphragm to a core plate made of this type of synthetic resin, if you try to attach it with screws, etc., the strength of the synthetic resin is insufficient, and if you use inserts, etc. to reinforce this, it will be difficult to process and assemble it. This required a lot of work and was not strong enough.

In addition, when the core plate and diaphragm are made of the same synthetic resin and then bonded together, advanced bonding technology is required to maintain sufficient strength at the bonded part, which is expensive. was there.

However, in this invention, as mentioned above, the core plate 1 and the diaphragms 4, 4 are configured separately, and in order to assemble them together, there is no need to screw the synthetic resin material, which lacks strength. , only the sealing part is secured for both, and in order to join the two, the left and right diaphragms 4, 4 are fastened together.The operation is extremely simple, and it is different from conventional devices of this type. All of the difficulties have been resolved.

The reason why synthetic resin core plates are used is that synthetic resins are much lighter than metals such as castings and have chemical resistance.If chemical resistance is required, diaphragms 4 and 4 are used. Of course, synthetic resin is also used, and sealing material 2 is also used.
Also, a material having corrosion resistance is used.

As detailed above, the device according to this invention is cheaper to manufacture and easier to assemble than conventional devices of this type, and it also has practical advantages such as being able to form a perfect seal during use. The benefits gained are enormous.
