Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for separating lacrimal fluid and P by filtering or compressing the stock solution.
The present invention relates to a filter press that separates into residues, and in particular to an improvement of a HTi furnace fluid stripping device used for each furnace plate or pressing furnace plate.

Conventionally, in the Pffi traveling type filter press,
When the frame of the filter press is opened, the stock solution is filtered through the Fi.
In order to collect the furnace fluid that has adhered to the surface of the Fffi, a tear fluid removal member such as a scraper is brought into contact with the surface of the Fffi, and the furnace fluid is removed from the Fffi.
It is known that the surface is rubbed off from i.

However, when scraping lachrymal fluid from Pf5 using a scraper or the like as described above, the scraper runs the furnace cloth between the lachrymal fluid adhering to Pf5 and the Pf5, and does not scrape the surface of H5, thereby peeling off the P residue. , the surface of the P can was easily damaged by the scraper, which had the disadvantage of shortening the life of the Fffi.

In view of the above-mentioned problem, the present inventor provided a lachrymal fluid stripping member consisting of a pair of plate-like members between which a slit passage for Fffi to pass between a pair of support frames supported below the furnace plate, and An application was previously filed for a filter press in which a wedge-shaped edge portion was formed on the upper edge of one of the plate-like members that slidably contacts the surface side of the F45.

However, since the above-mentioned furnace liquid sliding member was fixed within the thickness of the furnace plate so as not to interfere with the tightening of the Pf5, it was necessary to bend the running path of Pf5 slightly inside the furnace plate. Due to this bending, the outer surface of the oven cloth is rubbed by the edge of the upper edge of the lachrymal fluid stripping member, causing an overload on the running of the oven cloth and causing wear of the Pffi during long-term running.

Therefore, in the present invention, the slit of the P residue peeling member through which Pfl'i passes is set to
Pff
It is an object of the present invention to provide a filter press that does not apply an overload to the i-traveling, can reliably prevent wear of the F operation, and can effectively remove furnace liquid adhering to the F can.

The filter press according to the present invention is a furnace between support frames.

When a furnace plate is opened by rotatably supporting a furnace liquid peeling member that has a slit through which Pffi passes and peels off the furnace liquid attached to the H5 above, on a shaft provided above the cloth take-up roller. In this step, the furnace liquid peeling member is rotated by 5Pffi expanded by the biasing force of the spring of the Pffi take-up roller, and the slit is positioned on the downward running path in the substantially vertical direction of Pffi, while the furnace plate is rotated. The furnace liquid separating member is characterized in that when it is tightened, the furnace liquid separating member rotates and is housed within the thickness of the furnace plate.

Further, on the upper part of the pair of support frames 19.19, an outer plate 2 is provided.
A furnace liquid peeling member 25 having a slit 24 formed between a pair of plate members 2 and an inner plate 23 is rotatably supported via a support roller 26.

The outer plate 22 is an elongated plate member that is longer than the width of the Pffil 6 and has a substantially triangular cross section that protrudes to the outside of the oven plate 5, and has a lacrimal fluid peeling edge 22a formed on its upper edge.

On the other hand, the inner plate 23 is a plate material having approximately the same length as the outer plate 22, and its both ends are thin-walled portions 23a, 23a.
It is said that

Between each thin portion 23a and each end of the outer plate 22,
A thin plate 27 having a thickness substantially equal to the thickness of the Pffil 6 is sandwiched between the thin plates 27 and attached to a support roller 26 pivotally supported between the support frames 19 and 19 via a bracket 28 to form a slit having a width substantially equal to the thickness of the Pffil 6. 24 is positioned on the substantially vertically downward travel path of the Pffil 6 by rotation of the support roller 26, so that only the Pffil 6 is allowed to pass through.

Therefore, each furnace liquid peeling member 25 is rotatably supported by the support roller 26 between the support frames below the furnace plate, with the inner plates 23 facing each other.

And, the tuning board 5. . . , 5, as shown in FIG. 5, the furnace liquid stripping member 25 is rotated together with the support roller 26 in the direction of the arrow in the figure by the spring force of the torsion spring of the H'5 take-up roller 20. The slit 24 of the furnace fluid stripping member 25 is positioned in the substantially vertically downward traveling path of the furnace cloth 16, without damaging the Pffi surface by the upper edge 22a of the outer plate 22 of the furnace fluid stripping member 25.

From there, P is supplied via the stock solution supply port 5c of each furnace plate 5 (see FIG. 2) and the stock solution supply fitting 16a attached to each -P can 16.
The stock solution press-fitted between f516.16 is separated into tear fluid and F fluid, and the separated P fluid is collected from the P fluid collection tube 33 to perform filtration.

When one filtration process is completed and the movable plate 7 is retreated to position A in FIG.
As shown in FIG. 3, the PS banks 5 connected in order from the sides are opened all at once, keeping a constant interval from each other.

At the same time as the frame is opened, a portion of the separated furnace liquid falls down due to gravity while remaining in the form of a cake.

At the stage when some of the tear fluid has fallen, Pffi16 is P5.
It is expanded slightly away from the center, and at this stage,
When the motor 13 is decelerated and driven in the rewinding direction, and the left and right drive shafts 9 are used to unwind the hanging cord 15 that is wound around the take-up boob IJ11, 11, when it is twisted at its maximum twist. rotates the winding roller 20 in the winding direction with a strong spring force.

Due to the winding rotation of the winding roller 20 due to this spring force,
The P cans 16-1 and 16-2 on both sides of each furnace plate 5 pass through each sludge removing member 25, thereby removing the Pffi 16-1.
The tear fluid 29 remaining in 16-2 is
Peel it off.

Note that cleaning of each Fffi 16 by the cleaning pipe 32 is performed as appropriate when winding up the P cloth or unwinding the Ff5.

In this embodiment, the slit 24 is formed by interposing the thin plate 27 between the outer plate 22 and the inner plate 23. Therefore, the slit 24 can be formed by changing the thickness of the thin plate 27.
The width can be easily changed and can be used for various Pffi16.

In addition, since the P cloth 16 is made to pass through the slit 24 having a width approximately equal to the thickness of the furnace cloth 16, the furnace liquid 29 attached to the P year 16 can be removed, which cannot be removed with the conventional scraper V-pa. Even caked-on furnace fluid can be removed cleanly and smoothly.

Note that the present invention is not limited to the above embodiments,
It can be implemented in various ways.

For example, in the above embodiment, the furnace liquid stripping member 25 is provided above the support roller 26, but conversely, the furnace liquid separation member 25 may be provided below the support roller 26.

As detailed in the above embodiment, the filter press according to the present invention has a slit in the shaft provided above the furnace cloth take-up roller between a pair of support frames, through which the F can passes, and is attached to the P can. When the furnace plate is opened with the furnace liquid peeling member for peeling off the lachrymal fluid rotatably supported, the above-mentioned '? When the furnace liquid stripping member is rotated by the P can expanded by the biasing force of the spring of the P can take-up roller, and the furnace plate is tightened while the slit is positioned on the approximately vertically downward travel path of H5. In this case, the furnace liquid peeling member rotates and is housed within the thickness of the furnace plate, so that no overload is applied to Pffi running and wear of Pf5 can be reliably prevented. At the same time, the furnace fluid adhering to the Fffi can be peeled off well, while the tightening of the furnace plate is not hindered.
