Abstract

PURPOSE:To prevent the movement of a packing and the loosening or the sag of filter cloth and a net-like substance, by a method wherein a filter frame having the net-like substance arranged to the innner peripheral surface thereof is covered and clamped with filter cloth and a seal material is attached to the filter cloth adjacent to a filter plate along both side surfaces thereof. CONSTITUTION:A net-like substance 5 is arranged to the inner peripheral surface of the frame body 12 of the filter frame 2 in a multiple filter press and the whole is clamped by filter cloth 4. A seal material, for example, an O-ring is arranged to the side surface of the clamping filter cloth 4 and enclosed in a cylindrical part formed by sewing both sides of a tape 11 and the filter cloth 4. In addition, because a spacer 15 limiting the collapse of the O-ring is attached to the frame body 12 while a water draining net like substance 16 is attached to the surface of the plate body 13 of the filter plate 3, processing cost is made low and a seal material 10 is not moved while the net-like strip plate clamping filter cloth 4 is not loosened and the sag of a net-like strip plate 5 is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dual filter press frame.

As shown in Fig. 1, the duplex filter press 1 has a T-frame 2 and a plate 3 arranged in close contact with each other, and a series of F-frames and a plate are tightly connected. The highly concentrated muddy water from the wastewater purification equipment used in the gravel plant and shield excavation method is injected, separated into water and cake, and after being tied, the frame is opened and the cake is removed from the four-neck plate. . The relationship between the 1-f frame 2 and the furnace plate 3 can be further expanded as shown in FIG.
2 is covered with 1 cloth 4, and P plate 3 is also covered with plate body 13.
It is covered with cloth 4. The f frame 3 will be explained with reference to FIG. A tightening cloth 4 is wrapped together with a frame 12 and fixed to the frame 12 to form a sag frame 2.

Although not shown, the frame 12 is provided with a small hole for draining water that opens on the inner peripheral surface and penetrates to the outer peripheral surface. At the part where the f-frame 2 and the f-board 3 come into contact, a hole is arranged so as to have a watertight structure.

Various means have been tried in the past regarding the watertight horizontal shaft between the t1 frame 2 and the 1 plate 3. FIG. 3 shows a method in which a flat band-shaped rubber backing 6 is attached to the plate body 13 on the side of the plank plate 3 with adhesive or screws. However, with repeated use, the adhesive may peel off due to deformation of the rubber, and the holes in the rubber packing may enlarge due to the screws, causing the seal to fall off. In the figure, 7 is a spacer.

FIG. 4 shows a system in which a flat band-shaped rubber backing 6 is attached to the frame 12 on the r-frame 2 side with adhesive or screws.

If this is also used repeatedly, the rubber backing 6 will become a mesh material 5.
It stays in the tightening cloth 4 and does not fall off, but the rubber backing 6 is compressed and deformed and permanently expanded, and the tightening cloth 4 loosens and rotates around the frame 12 to become a fixed tightening cloth. There are drawbacks such as the seam 10 being caught between the flat plate 3 and the 1 frame number, rendering the seal meaningless. Furthermore, if the cloth 4 becomes loose, the adhesive of the water draining mesh material 5 may peel off, become frayed, or sag, rendering it useless for draining water.

Furthermore, Fig. 5 shows a structure in which a groove 9 is formed in the frame body 12 of the p-frame 2 and an O-ring 8 is attached. However, the corner welds of the grooved parts require hand finishing, which increases the processing cost, and although the sealing effect is certain, it is not economical.

Although the present invention attempts to solve these conventional drawbacks, it has the following drawbacks: (1) the rubber bolt (the binding moves from its fixed position on the frame), (2) the tightening cloth for the net-like material loosens, and (2) the net-like material The purpose is to solve shortcomings such as sagging.

That is, the present invention arranges a mesh material on the inner circumferential surface of one frame of a dual filter press, and P
In an r-frame covered with cloth and tightened.

A t adjacent to the 7P cloth that covered and tightened the frame of the one frame.
The gist of this filter press is one frame in which a sealing material is arranged along both sides in contact with four plates, and the sole material is attached to a tightening fabric using a tape-like material.

Next, drawings about the present invention? This will be explained in detail using

In FIG. 6, reference numeral 4 denotes a tightening hole for a mesh material 5 arranged on the inner circumferential surface of the frame body 12 of the P frame 2, and a sealing material 10 is arranged on the tightening cloth 4, and this sealing material lO is It is wrapped in a cylindrical part which is completely sewn together with both sides of the tape 11 and the two cloths 4. In the figure, 15 is SHE-f-.

Reference numeral 16 denotes a net-like material for draining water (which is stretched over the surface of the plate 12 in the plate 3).

FIG. 7 shows a plan view of the sealing material attached to the r frame.

As shown in FIG. 7, the tape 11 is not sewn at the corner;
The sealing material 10, for example, 01 nong, can be easily passed therethrough, and the sealing material 10 is used as a joint for an 0 ring.

In addition, as shown in Fig. 8, the O-ring diameter d and the cloth tape.

The relationship between the sewing width a and the ease of threading the O ring and o I
From the relationship of J song retention, 2d < a < 4d
The force is appropriate. - As an example, the O-ring diameter is 5 inches, the sewing width is 19111=IN, and the f fabric 4 is loosened enough to fit the O-ring.

Also, the spacer 15 that limits the crushing margin of the IJ song may be attached to the flat plate 3 outside the f frame. Alternatively, it may be attached to the f-frame 2 as shown in FIG.

As explained above, one frame to which the sealing material is attached can be sewn, so the processing cost is low, the sealing material 10 does not move, the cloth for tightening the mesh band does not loosen, and the mesh band tightens. It does not sag, and there is no need to cut grooves in expensive steel materials, and its industrial benefits are great.
