Abstract

PURPOSE:To provide a titled screen which has simple construction and good efficiency, by the constitution wherein a pair of wire members are fixed on both sides of support rods with said rods in-between, and the plural slits and smooth surfaces expanding toward the inner side are formed with the respective wire members. CONSTITUTION:Inner wire members 2 consisting of plural annular wires 2a are stuck to the inner side of plural support rods 3 arranged in a cylindrical shape at prescribed intervals and spirally wound outer wire members 4 are stuck on the outer side thereof, whereby a cylindrical double surfaced screen 1 is obtained. The members 2 are formed by welding the wires 2a consisting of wedge wires having a wedge shape in section by fusion to the rods 3 at equal intervals so as to form slits 2b. The wedge wires are spirally wound around the outer side so as to form slits 4a of prescribed sizes and are welded by fusion to the rods, whereby the members 4 are formed. With either members, the projecting base parts of the wedge shape are welded by fusion to the rods 3 to form the smooth outside surfaces in parallel with said rods.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an ant-like meat-surface screen as a touch gl & am receiver in the device.

In catalyst production, two or more types of catalysts are sometimes used in one device. The catalyst receivers conventionally used in such cases often have a complicated structure and a high fit. Therefore, the present project is aimed at improving the structure of catalyst receivers that use two or more types of catalysts. The purpose of the catalyst receiver is to provide a screen V with a simple structure and high efficiency that can be used for various purposes.

The double-sided surface screen according to the present invention includes a plurality of support rods arranged at predetermined intervals, and a plurality of slits at a predetermined pitch in a direction substantially perpendicular to the /-10 angle between the plurality of support rods. a pair of wire members fixed to the I-trorad so as to form a wire support rod, each wire comprising the pair of wire members having a smooth outer surface parallel to the support rod;
The slit between the HI valley wires is slightly inward,
It is characterized by having a #r surface shape that spreads out.

The present invention will be explained in detail with reference to Example 9 shown below.

The present invention can also be applied to screens having a cylindrical, arcuate or flat plate shape.

FIGS. 1 and 2 show an example in which the present invention is applied to a cylindrical double-sided screen.

In the embodiment shown in FIG. 1, the double side view screen 1 comprises a plurality of screens arranged generally cylindrically as a whole. 4-Trokudo 3, an internal wire member 2 consisting of a ring-shaped wire 2a with ** disposed inside 1141 of this support rod 3, and a plurality of wire members 41 arranged in a spiral shape on the outside of the rod 3. The outer wire member 4 that has been marked is placed 1.

The internal information wire member 2 is formed by arranging a large number of wires 2a made of M-plane wedge-shaped wedge wires at equal intervals in the axial direction so as to form slits 2k between adjacent wires. The wedge-shaped protruding bases of the wires 2a are arranged in the axial direction with a fixed mechanism made of a plurality of metal rods, and the wires 2a are brought into contact with each other. 1llIII points! The 8-piece wire member 2 is fixed to the 1/-10 piece 3 by the screws.

The internal wire member 2 may be formed by wrapping a wedge wire in a spiral shape.

Outside the support rod 3, a wedge wire made of IIIK gold is spirally wound (2) so as to form a slit 4a of a predetermined size (5) to form an outside wire member 4. The outer wire members 4 and /-10 wire members 3 are welded at their mutual contact points. The wire members 2 and 4 are wedge wires in the illustrated embodiment, but are not limited to trapezoidal, triangular, etc. etc., if it has a smooth surface parallel to the support rod when attached to the support rod, and has a cross-sectional shape such that the slit between adjacent wires gradually widens toward the inside 111, The e-trod and the I-trod are not limited to a circular shape, but may have a rectangular or elliptical cross-sectional shape such as a square shape.

In order to manufacture such a screen according to the present invention, in addition to the above-described method of attaching the same wire member 2 to the trod 3 and further placing the outer wire member 4 on the outside thereof, it is also possible to arrange the screen in the 8 bulk directions. **Inner information Rear member 2 consisting of an assembly with wire member 4 #11 and a spiral wedge wire is prepared separately, and this inner wire member 2v is inside of support rod 3.
If the present invention is formed into a cylindrical shape and is developed by such screen secondary processing, a flat a-wipe 1111 surface screen as shown in Part 3 is superior. It will be done. Similarly, I
It is also possible to obtain a Jll-shaped screen.

In the case of a flat type, it is preferable that each wire is a part of the rod.In this case, the inner slit and the outer slit of the screen may be of the same size, or they may be made mutually. It can be made into dimensions,
゛Also, the screen according to the present invention can be formed from materials such as synthetic 4II skin, glass twill A-, etc., instead of metal. It is.

Among the above configurations, an example of the use of the 1111 front-facing star ν- is shown in the 4th example, in which the catalytic converter is equipped with a ura surface screen 1 to separate and hold different types of catalysts a and b. Both III* of the present invention According to the meat screen, since the screen surface is smooth, the catalyst can move smoothly and will not damage the fallen catalyst.
In addition, since the slits between each wire are shaped to gradually widen within 111K, there is almost no possibility that catalyst particles will get caught between the wires and cause clogging.Therefore, the screen of the present invention is suitable for use in mobile catalyst devices. I'm afraid to wear that effect. ! In addition, it has a structure in which the inner wire member, the rod, and the outer wire member are integrated, and each wire member is reinforced with #A to each other, so it is a simple and compact structure but extremely strong. Therefore, the catalyst can be held sufficiently even in a large-sized catalyst device. In addition, the slits also allow for the placement of the fluid passing through the catalyst layer.
ff effect can be obtained. Furthermore, in the event that the catalyst becomes clogged, the screen can be cleaned by shaking the water in the opposite direction. The flesh-sensation display screen according to the present invention, which has the effect of
-) It can be used for various purposes.
