Abstract

PURPOSE:To perform the raising and falling of a liquid permeable perforated plate for compacting or supporting flexible fiber bundles and the compaction of fiber bundles, by the mechanical manipulation of water (oil) pressure, the elastic force of a spring, an eccentric cam and a lever. CONSTITUTION:For example, when the elastic force of a spring is used in the compaction of fiber bundles, a perforated plate 3 for compacting the fiber bundles is upwardly urged under pressure by the elastic force of the spring to form a filter bed through the compaction of fiber bundles 2. The floated suspended substance in the stock liquid flowed in from a stock liquid supply pipe 7 is collected by the filter bed comprising the fiber bundles. When the clogging of the filter bed advances and liquid passing resistance increases, the stock liquid supply pipe 7 and a filtrate discharge pipe 6 are closed while a concentrate discharge pipe 8 and a washing liquid supply pipe 9 are opened and the top part of the spring 4 is pushed. The perforated plate 3 for compacting fiber bundles is pushed down through a connection lever 5 and the fiber bundles 2 are suspended to be brought to a stretched open state. After washing and regeneration, force applied to the top part of the spring is released whereupon the filter bed is again formed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides (1) a large number of flexible fibers in a fully consolidated state;
When all the suspended matter in the liquid is filtered and collected, and (i+) the suspended matter captured by the fibers 1- is removed, the liquid-permeable porous plate for compacting the fiber bundle is released, and the fiber bundle is stretched and released. This is for all purposes.

The inventor of the present invention first developed a fiber bundle supporting porous plate (5) in which one end of a large number of flexible fibers was fully fixed to a liquid-permeable porous plate and the other end hung freely, and a fiber bundle supporting porous plate (5) was integrated with a float to provide buoyancy. A structure that can be raised and lowered freely? We have invented a filtration device consisting of a pair of liquid-permeable perforated plates for consolidating fiber bundles.

In place of the buoyancy of the float of the previous invention, the present invention utilizes mechanical operations such as water (oil) pressure, elastic force of springs, eccentric cams, and rams to produce a perforated plate for consolidating fiber bundles or for supporting fiber bundles. This is a filtration device whose main functions are raising and lowering a perforated liquid-permeable plate and compacting a fiber bundle.

Prior to the present invention, organic "!fc" was made by completely consolidating inorganic fiber bundles, adhering or semi-welding, and forming a flat or cylindrical air-permeable porous body as a p-body to filter suspended matter in a liquid. There are many examples of it being used for collection.

Materials such as base paper, non-woven fabric, glass fiber mat, ceramic tube, and polypropylene fiber bundle are available in cylindrical cartridges.

However, with conventional products, after one use, suspended particles are deeply entrenched in the fine pores, and it is difficult to completely regenerate them using conventional methods such as washing or showering. It was common for the equipment to be damaged, and this was one of the reasons for the soaring costs.

In other methods, wire mesh and cloth bags are often used, and although these can be recycled relatively easily, they only collect the surface layer, so they clog quickly and require frequent recycling operations. There were drawbacks.

In the inventive filtration device, unlike conventional methods such as this, ■ When the liquid passes through, the fiber bundle is fully consolidated using a perforated plate, making it as dense as animal hair felt or cotton mat. Forms a hearth, obtains a good temporary effect, and ○
When removing the collected suspension cookie and washing and regenerating the fiber bundle, the perforated plate for consolidation is completely removed and the fiber bundle is fully stretched and released, so the spacing between the fibers is widened, and the fibers are close to Table 1 and The suspended matter collected and deposited between the fibers in the deep layer can be completely removed and regenerated deep by conventional methods such as backwashing and showering, so it has the advantage of being able to be used repeatedly.

In short, it consists of a pair of objects (2) with one end of a flexible fiber bundle fixed to a perforated plate and the other end left open, and a perforated plate (Bl) for press-welding the fiber bundle. The filtration device compensates for the drawbacks of the conventional device and has completed a high-performance and economical device.In the previous invention, which the present inventor has already applied for, the buoyancy of the float is used to apply pressure and release the device. In contrast, in the present invention, %
The fiber bundle crimping plate and the fiber bundle support plate are pressed together and separated by mechanical methods such as water (oil) pressure, elastic force of springs, cams, rams, and gears. It is something to do. These mechanical methods are used alone in actual equipment,
Alternatively, various forms can be taken by combining them. Specific examples will be explained in the following examples.

The fiber bundle used in the filtration device according to the present invention includes wool,
In addition to natural fibers such as cotton, it has durability, toughness, processability (adjustment of thickness, solidity of adhesive fixation), heat resistance, and chemical functions (adsorption, hydrophilicity, lipophilicity, etc.) ),
Synthetic fibers are often used due to their low biodegradability and chemical resistance.

As long as the thickness of the fiber is flexible, hn is sufficient, but the stronger the thinner fibers are compressed, the better the precision is, but if the fibers are too thin, they are easy to cut and have the disadvantage of increasing resistance to fluid passage. Since it comes out, the limit is 6. The selection is made taking into account the properties of the filtrate stock solution and the expected accuracy, but I think that approximately 5 to 30 denier is appropriate.

Although the fibers can be used either as a single wire or as a twisted yarn, the use of a single wire has been shown to be effective in terms of fully enhancing the recycle cleaning effect and preventing the fibers from colliding together due to twisting.

MI damage old responsibility 枇田久 11 1/r Adhering to Saisenichi, Nasu Yukio attaches the fiber bundle to the support rod in an inverted U-shape (Figure 7 (3)) or O-shape (B), one end of which is gold. It is recommended to use a hook to hold it all down, or to fix it with adhesive. (8th
(Figure) As shown in Figure 6, in addition to the parallel rods (5), concentric ring (B), lattice, or net supports may also be used.

As a material that can be used equivalently to the hearth made of supported fiber bundles produced by the above method, there is also a material woven on one side of a flexible full-fiber fabric, commonly known as ``long-haired fabric''. .

This will be specifically explained below using examples.

Example 1 Example 1 is an example in which spring elastic force was used to compact the fiber bundle.

During the fault operation, as shown in FIG. 1(3), the fiber bundle consolidation porous plate 31-j is pressed upward by the elastic force of the spring 40, consolidating the fiber bundle 2 and forming a good hearth.

Rumored to be a slow imitation of Japanese cuisine h+, -; Ichikasa kasuri rust≠! If the amount increases, close the stock solution supply pipe 7 and the filtrate discharge pipe, open the concentrated solution discharge pipe 8 and the washing solution supply pipe 9, and press the spring top to open the fiber bundle consolidation porous hole through the connecting ring 5. The plate 3 is pushed down, and the fiber bundle 2 hangs down, stretches, and becomes open.

The fiber bundles are sufficiently washed by the cleaning solution remaining in the upper hearth chamber and the washing solution applied from outside.

After cleaning and regeneration, when the force applied to the top of the spring is removed, the elasticity of the spring returns it to its captive state, allowing it to be used repeatedly for filtration operations.

Example 2 4 Fig. 2 shows a mechanism that combines an eccentric cam, spring elasticity, and hand wheels to raise and lower the perforated plate 3 for consolidating fiber bundles, and to control the total fiber bundle pressure ff1 (criminal operation prisoner) and drooping stretching [washing regeneration operation]. 03
) ) ' is what is done.

The perforated plate 3 for consolidating fiber bundles, the operation during the cleaning operation of fiber bundles, etc. are the same as in the first embodiment.

Example 3 This is an example in which the holding porous plate is raised and lowered to perform all the consolidation and hanging stretching of the fiber bundle. It has a built-in 16-karat gold hydraulic piston and can move up and down a perforated plate for supporting fiber bundles, which is integrated with the piston via a connecting ring 5.

Example 4 Figure 4 is an example in which the porous plate 3 for consolidating fiber bundles is raised and lowered using water (hydraulic pressure machine and spring elasticity). By doing so, it is possible to prevent excessive or insufficient pressure contact force and obtain a stable pressure bonding effect.

Embodiment 5 FIG. 5 is an example in which a water (hydraulic) machine, spring elasticity, and buoyancy of a float are combined. By combining the entire buoyancy of the float 17 with the mechanism of the fourth embodiment shown in FIG. 4, it is possible to save hydraulic power and obtain a more stable fiber bundle consolidation effect than in the fourth embodiment.

Example 6 [Fiber bundle support method (1)] Fig. 6 (5) shows an example of parallel rod-shaped supports, and Fig. 6 (B) shows an example of concentric monkey-shaped supports.

Example 7 [Fiber bundle support method (++)] Figure 7 (5) shows the fiber bundle in an inverted U shape, and (B) shows the fiber bundle in a 0. One end is hung in the shape of a letter and hung down, and the other end is fixed with a metal fitting 23.

Example 8 [Fiber bundle support method] Figure 8 shows a fiber bundle made of synthetic fibers, one end of which has been completely melted and then cooled and solidified, placed in a partially cut-out cylinder, and bonded. 0 indicates that it has been hardened and fixed with an agent.
