Description

  The present invention relates to a method for forming an outer flow port of a square shifter.

The square shifter is formed by stacking square sieve frames and storing them in the sieve body, using the falling passage formed by the drop opening of the sieve frame itself and the gap between the sieve frame and the inner wall of the sieve body. Separation of the sieved powder is performed.
When using a drop passage formed by a gap between the sieve frame and the inner wall of the sieve body, an outer flow port is formed in the laminated sieve frame, and the powder sieved by the sieve frame is guided to the drop passage through the outer flow port. Yes.

Japanese Patent Laid-Open No. 50-88666

In the special sieve frame provided with the receiving plate so as to form the outer flow port, there is a problem that the powder passage is likely to stay in the corner portion of the receiving plate and the powder passage is blocked.
Moreover, when adjusting the size of the outer flow outlet, it is necessary to prepare special sieve frames with different heights, which is not economical.
Further, the cleaner drop prevention pin can only be provided in the vertical direction, and the cleaning efficiency is poor.
Even in a special empty frame in which the powder is dropped out of the sieve frame with the L-shaped angle shape using the synthetic resin, the powder passage is likely to occur in the corner portions 82 and 83 of the receiving plate. There was a problem that was interrupted.
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a method for forming an outflow port of a square shifter that is easy to handle and easy to clean.

As a result of intensive research to achieve the above-mentioned object, the present inventors corresponded to the receiving plate between a sieve frame in which a sieve screen is stretched and an empty frame provided with a rectangular receiving plate on the side. In order to complete the present invention, it is found that an outer flow port can be formed by placing one or more empty frames sandwiched between three or more empty frames so that the outer wall at the position where the outer wall is removed and the inner three sides are stacked. It came.
Accordingly, the present invention relates to a method for laminating a sieve frame used for a square shifter, wherein the sieve frame is provided with a sieve screen provided with a sealing surface under the inner wall (156) of the drop port (155) of the standard sieve frame. (150) and a pair of inner walls facing in parallel to the inner side of the outer wall, and a rectangular receiving plate (101) and a U-shaped sealing surface (104) are provided on one side different from the outer wall provided with the inner wall. A pair of inner walls facing in parallel with the inner side of the outer wall between the empty frames (152) , the outer wall (111) on one side different from the outer wall provided with the inner wall is missing, and the outer wall (111) is missing A method of forming an overflow port (157) over which one or more empty frames (151) provided with a U-shaped sealing surface (114) are placed so that each sealing surface is on the same side . And a method for laminating a sieve frame used for a square shifter, and A standard sieve frame (170) and a pair of inner walls facing the inside of the outer wall in parallel are provided, and a rectangular backing plate (121) and a U-shaped sealing surface (124) are provided on one side of the inner wall. A pair of inner walls facing the inner side of the outer wall is provided between the empty frames (172). The outer wall (131) on one side where the inner wall is provided is missing and the outer wall (131) is missing on the side where the outer wall (131) is missing. This is a method of forming an outflow outlet (175) in which an empty frame (171) provided with the seal surface (134) is placed so that one or more sheets are sandwiched so that each seal surface is on the same side .

In the case of missing, it can be used with a standard sieve frame, so there is no need to prepare many special sieve frames.
The size of the outer flow port can be easily adjusted by adjusting the number of stacked empty frames with the outer wall missing.
