Patent document
Patent document 1：No. 4276265 specifications of U.S. Patent No.
The content of the invention
But although the front end of the tab up and down of the passage component is multiple with extending along the vertical direction of filter screen
Thread-like member is soldered and forms enclosure space, but the tab of neighbouring passage component is not welded each other.Therefore,
The tab of neighbouring passage component there may be gap each other.
At this point, it is necessary to make what is generated on the inside of its pipe due to the chemical reaction with catalyst granules for filter screen
The heterogeneous gas such as propylene are from the enclosure space of each lower channel component uniformly across on the outside of pipe.
But if there are gap between the tab of neighbouring passage component, on the inside of the pipe of filter screen
The partial compromise that the heterogeneous gas such as the propylene of generation are possible to beyond the enclosure space of each passage component is gone out.Thus,
It can not just make the heterogeneous gas such as the propylene on the inside of the pipe of filter screen empty with the closing of controlled state from upper and lower each passage component
Between uniformly across on the outside of pipe, the reliability of filter screen reduces.
From this angle, there has been proposed substituting the passage component using box part, the box part have by
The basic filter screen that each thread-like member and multiple elongated members (being equivalent to upper and lower tab) are formed, the plurality of elongated member
Radial direction inner end respectively with each thread-like member weld, and according on the vertical direction of filter screen across equally spaced
Circumferentially extending of the mode along the filter screen, and the box part also there are multiple peripheral side plates (to be equivalent to periphery side plate
Piece), self adjacent each strip in the basis filter screen is respectively welded in the upper and lower ends of the plurality of peripheral side plate
The radial direction outboard end of component, and along the circumferentially extending of filter screen.In this case, for box part, half
Footpath direction inner end is welded on the radial direction outboard end of each elongated member of each thread-like member and is respectively welded peripheral side
The upper and lower ends of plate, the closing that the box-like circumferentially extended is thus respectively formed in the both sides up and down of each elongated member are empty

That is, it is necessary to self adjacent each strip in multiple elongated members of the circumferentially extending along filter screen
The upper and lower ends of peripheral side plate are respectively welded in the radial direction outboard end of shape component, and operation is very miscellaneous, furthermore, it is desirable to make
The industry time.
Accordingly, it is considered to which the box part is formed with the basic filter screen and following plate, which is welded separately
In the radial direction outboard end of each elongated member of the basis filter screen, and with the peripheral side of a tablet structure filter screen
Face.In this case, between each elongated member adjacent with self corresponding plate corresponding position
Install be equipped with make heterogeneous gas from the inside of the pipe of filter screen by the perforate on the outside of pipe.
But on the box part that the plate for the circumferential lateral surface for building the filter screen with tablet is used to obtain,
When plate to be welded on to the radial direction outboard end of each elongated member of basic filter screen, each elongated member can not be confirmed
Radial direction outboard end, therefore, it is possible in the welding for the radial direction outboard end that plate is welded in each elongated member
It is led to the problem of in operation and reliability is reduced.
