JP4670116B2 - Contactless bends that do not touch the package - Google Patents

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention has been developed as a bend for piping parts with high wear used for transported goods with high hardness (for example, sand, metal, glass, etc.).
[0002]
[Prior art]
Various measures have been taken for conventional bends (for example, guide vanes inside, high silicon cast iron pipes, ceramic lining, etc.), all of which are in direct contact with the transported goods. . For this reason, the life of the wear progress time was extended.
[0003]
[Problems to be solved by the invention]
A bend is a piping component that changes the direction of a transported item, and has the greatest degree of wear. Further, since the places where the transported goods come into contact are concentrated in one place, the wear frequency is extremely high even when compared with the piping of the series.
[0004]
[Means for Solving the Problems]
The present invention makes use of the property that the object moves in a straight line and retains the transported goods at the place where they are worn, so that it can have a role as a cushioning material, and the transported goods and the bend main body can be in direct contact with each other. Disappear.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
From FIG. 1, the short pipe 3 and the short pipe 9 are members each having a flange fixed to both ends of a short pipe, the inlet nozzle 4 and the outlet nozzle 7 are each fixed to a flange at one end of the pipe, and the other end is left as it is. It is a member.
A package 5 transported from the pipe 1 in the direction of arrow 2 through the nozzle 4 enters the bend body 6. The bend body 6 includes a side plate 18 and a buffer chamber 19 for the inspection lid 16. The first transported material 5 stays there and becomes a cushioning material (shaded diagram). When a certain amount is formed as a buffer material, the next transported material bounces on the surface of the buffer material 21, and the redirected transported material 8 is transported in the direction of arrow 10 of the pipe 11 through the outlet side nozzle 7. The
[0006]
As shown in FIG. 2, when the short pipe 3 is worn and needs to be replaced, the nozzle 4 can be easily renewed by removing the short pipe 3 without removing the bend body 6.
[0007]
As shown in FIG. 1, the nozzle 4 prevents the turbulent flow 22 of the transported material from being generated at the inlet flange portion 13 of the bend body 6 on the arrow 2 side and wearing the entrance portion of the bend body 6.
[0008]
As shown in FIG. 2, the bend main body 6 is processed with a steel plate made of a material corresponding to the pipe, and a buffer chamber 19 for the side plate 18 and the inspection lid 16 is provided.
[0009]
1, the buffer chamber 19 becomes an inspection port when the inspection bolt 16 is removed by loosening the push bolt 17 of the metal fitting 15 for fixing the inspection lid 16, and cleaning of the residue of the transported goods 5 and wear of the nozzles 4 and 7 are observed. Can be observed.
[0010]
As shown in FIG. 1, the nozzle 7 prevents the turbulent flow 20 of the transported matter from being generated at the outlet flange portion 13 of the bend main body 6 on the arrow 10 side and wearing out the outlet portion of the bend main body 6.
[0011]
From FIG. 2, the short tube 9, when the nozzle 7 requires replacement worn, without removing the bend body 6, can be updated easily nozzle 7 By removing the short pipe 9.
[0012]
【The invention's effect】
The present invention is configured as described above, and by forming the package as a cushioning material, the wear of the bend body is drastically reduced, and the cost associated with renewal can be reduced.
[0013]
By eliminating the contact between the transport object and the bend main body, there is no need for an internal lining made of expensive high silicon cast iron or ceramic, construction and handling are easy, and production can be made at low cost.

FIG. 1 is a non-contact bend action diagram in which a package does not contact a bend body.
FIG. 2 is a cross-sectional view of contactless bend construction.
