Abstract

PURPOSE:To enlarge filtration area in a filter medium for fluid by joining sheet filter mediums which are arranged by facing alternately the surface and the surface, the back and the back to form a square or a rhombus and closing the end parts. CONSTITUTION:Sheet filter mediums 1, 2 wherein the surfaces (filtration surface) are alternately faced are joined by means of linear joined parts 3 paralleled in constant intervals. Also, sheet filter mediums 1' arranged by facing the backs are joined by means of joined parts 3'. When each contacted face is suitably separated in the direction of faces of sheet filter mediums, space IN surrounded with the surfaces of sheet filter mediums of rhombus or square and space OUT surrounded with the backs are formed and the closed parts are provided to the opposite end parts in end parts of each space IN and in space OUT to form fluid passages and fluid is entered from space IN and passed through the walls of the sheet filter mediums and flowed out from the space OUT.

The figure is a plan view showing the joining mode of the filter body of the present invention as seen from the inflow side (IN), and 1.2.1', ;2', etc. are furnace materials. The surfaces of the sheet furnace materials 1 and 2, that is, the filtration surfaces thereof, face each other, and they are joined by parallel linear joints 3'', 3, . . . at regular intervals. P indicates the pitch. II is a sheet furnace material placed with its back side facing the back surface of the sheet furnace material 2; It is joined by the part 3'.
A sheet furnace material 2' is further arranged on the back side, that is, the filtration surface, with the front surface (filtration surface) facing, and is joined to the joint portion 3' at a shifted pitch. By repeating the bonding in the same manner and separating the contact surfaces appropriately in the surface direction of the sheet furnace material,
A diamond-shaped or square space indicated by IN and OUT is formed. In this case, the space surrounded by the surface of the sheet furnace material is I
It is indicated by N, and the space surrounded by the back surface is indicated by OUT. These spaces are shown in Figure 2 as shown in the A-A' cross section.
A closing portion 4 is formed at the N end, while a closing portion 41 is provided at the opposite end of the OUT space to form a fluid passage. Therefore, when the fluid to be treated is supplied from the upper side (inflow side) in Fig. 2, the fluid flows into the spaces indicated by IN according to the arrows, passes through the walls of the sheet furnace material surrounding the four sides, and enters the space OUT. It flows out to the opposite side (outflow side).

なお前記の閉塞部４，４′の形成は、濾過体の取付外枠
と一体に成形する（例えば合成樹脂）などの加工手段を
採用すれば組立が著しく簡単となる。It should be noted that the formation of the aforementioned closing portions 4, 4' can be significantly simplified if a processing method such as molding (for example, synthetic resin) integrally with the mounting outer frame of the filter body is employed.

またシー）炉材の加工によりそのまま、例えば袋状に閉
塞してもよい。この場合更に濾過面積の増大が図れかつ
小型化し簡易化することができる。Alternatively, the furnace material may be closed as it is, for example, in the form of a bag, by processing the furnace material. In this case, the filtration area can be further increased, and the device can be made smaller and simpler.

合を行っても、使用上差支えない。Note that continuous processing is possible for joining the furnace materials using adhesive means such as thermal welding (thermoplastic synthetic fiber furnace materials) or hot melt (inheat-soluble crosswood), and the joints must be kept at the minimum required point. Even if it is joined, there is no problem in use.

法のものである。Furthermore, as a minimum unit, continuous processing can be performed in the longitudinal direction (X direction), and required dimensions (Y direction) can be obtained by increasing the number of sheet furnace materials. Further, the dimension H of the filter surface is a predetermined dimension.

きい。Since the filter body of the present invention is configured as described above, the F-shaped area is significantly increased and the size is reduced, and the reduction in offshore efficiency due to the close contact of the folds seen in conventional folded filter bodies can be avoided. There are no assembly problems, there is little shape resistance, and filtration can be performed with low pressure loss. It is also easy to manufacture, and products of the required size and excellent performance can be easily obtained.
It also has the advantage that it can be provided at a low price, and its effects are extremely large.
