Definitions
- the present invention relates to a bellows for a ring-shaped pressure vessel that seals the opening end of a bottomed cylindrical container body and the outer peripheral portion of a disperser that closes the opening end.
- the present invention relates to a bellows for a pressure vessel that is used in a state where it is placed in an unheated state from a heated state and is thermally expanded and contracted. Background art
- Pressure vessels as shown in Figs. 3 to 5 are used as an apparatus for polymerizing the resin.
- the pressure vessel is provided with a bottomed cylindrical vessel body 10 having an open end 11 and a bottomed cylindrical shape, and a lid 20 that closes the open end 11.
- a part 12 for polymerizing the resin is provided inside the container body 10.
- FIG. 5 is an enlarged schematic view of the main part of the pressure vessel shown in FIG. 3, but the basic configuration of the pressure vessel shown in FIG. 4 is the same.
- the outer peripheral portion of the upper surface of the dispersion plate 30 and the inner peripheral surface of the open end 11 of the container body 10 are sealed by a ring-shaped bellows 4 having a concave curved surface.
- the lower end edge of the bellows 4 is welded to the outer peripheral portion of the upper surface of the distribution plate 30, and the upper end edge of the bellows 4 is welded to the inner peripheral surface of the opening end portion 11 of the container body 10.
- the gap with 10 has been eliminated.
- the opening end 11 of the container body 10 is provided with an outward flange 14, and the outer periphery of the lid 20 is joined to the outward flange 14, and both the bolt 1 and the nut 2 11 , 2 0 is fixed.
- the lid 20 has a hemisphere or semi-elliptical shape as shown in FIG. 3 and a thick plate shape as shown in FIG.
- a number of jackets (not shown) through which high-temperature heat transfer oil of about 250 to 400 ° C flows are attached. Yes. further The inside of the pressure vessel is brought into a high vacuum state, and the raw material is partially poured into the lid 20. This raw material flows through the holes 31, 31... Of the dispersion plate 30 while being heated and flows down into the container body 10.
- the raw material does not cause the force between the container body 10 and the dispersion plate 30 to flow into the container body 10 due to the bellows 4.
- the raw material that has flowed down onto the bellows 4 moves toward the holes 31, 31, and so on of the dispersion plate 30 because the bellows 4 is formed in a concave curved surface, and the holes 31, 31,. ⁇ Flows down into the container body 10 from
- the raw material that has flowed down into the container body 10 is heated and polymerized with the parts 12, and the lower end portion force of the container body 10 is discharged from the resin. On bellows 4, the raw material is kept from staying, so that gel contamination due to thermal degradation can be prevented.
- the pressure vessel expands when heated, and contracts when the heating is completed. Therefore, the bellows 4 welded to the open end 11 of the container body 10 and the outer peripheral portion of the dispersion plate 30 also thermally shrinks. However, each edge of the bellows 4 is welded and restrained to the container body 10 and the dispersion plate 30, and is formed into a concave curved surface so that there is not enough excess to heat shrink. May occur. As a result, the bellows 4 breaks, and the liquid raw material stays in the gap between the dispersion plate 30 and the container body 10 to form gel and polymerize poor quality resin.
- an object of the present invention is to provide a bellows for a pressure vessel that is configured to have a squeezing force that does not break due to thermal expansion and contraction and a force that a raw material stays.
- a bellows for a pressure vessel is a bellows for a pressure vessel that seals the opening end of a bottomed cylindrical container body and the outer peripheral portion of a dispersion disc that closes the opening end in a ring shape. Therefore, a bent portion that is bent in the radial direction so as to be heat-expandable without being recessed is formed. [0013] According to the bellows for the pressure vessel, the bent portion that is bent in the radial direction so that it can be thermally expanded and contracted without being recessed is formed, so that the raw materials in the vessel body are reacted. When the temperature of the container body is increased or decreased, the bellows are not easily broken even if the container body or the distribution board is thermally expanded or contracted.
- the container body is fed with raw materials from the opening end side, and the dispersing disc is made to flow the raw materials down to the bottom side of the container body.
- the bent portion is formed so as not to retain the raw material. According to the bellows for the pressure vessel, since the bent portion is formed so as not to retain the raw material, the raw material poured into the container body does not stay on the bent portion. A gel can be produced to produce a product.
- the bent portion is formed by a concave curved surface and a convex curved surface that are continuous in a wave shape.
- the curved portion is formed so that the concave curved surface and the convex curved surface are continuous in a wave shape, and the convex curved surface is not restrained in the protruding direction or in the direction opposite to the protruding direction. It is possible to heat stretch.
- the concave curved surface is not formed in a depressed shape in which raw materials stay, for example.
- the opening end of the bottomed cylindrical container main body and the outer peripheral portion of the dispersion disc that closes the opening end are sealed in a ring shape and recessed.
- FIG. 1 is an enlarged sectional view showing an embodiment of a bellows for a pressure vessel according to the present invention.
- FIG. 2 is a partial cross-sectional schematic perspective view showing an embodiment of a bellows for a pressure vessel according to the present invention.
- FIG. 3 is a schematic sectional view showing an example of a pressure vessel.
- FIG. 5 is an enlarged sectional view showing a conventional bellows for a pressure vessel.
- this pressure vessel also includes a container body 10 having a bottomed vertical position provided with an open end 11 and a lid 20 that closes the open end 11.
- An outward flange 14 provided at the open end 11 of the main body 10 and an outer peripheral portion of the lid 20 are fastened by bolts 1 and nuts 2.
- a disperser 30 having a large number of holes 31, 31, ... is fixed in the open end 11 provided with the outward flange 14.
- the disperser 30 is fixed on a seat (not shown) projecting from the inner peripheral surface of the container main body 10, and a gap is formed between the inner surface of the container main body 10.
- the opening end 11 of the container body 10 and the outer peripheral portion of the dispersion plate 30 are sealed by a bellows 40.
- the bellows 40 is characterized in that a bent portion 41 that is bent in the radial direction so as to be thermally expandable without being recessed is formed. That is, as shown in FIGS. 1 and 2, the bellows 40 reacts and stops the raw materials in the container body 10, so that when the temperature of the container body 10 is raised or lowered, Even if the dispersion plate 30 is thermally expanded and contracted, the bent portion 41 is formed so as to be difficult to break! /.
- the bending portion 41 is formed by a concave curved surface 42 and a convex curved surface 43 whose radial cross section is continuous in a wavy shape. That is, a concave curved surface 42 is formed on each edge side of the bellows 40. A convex curved surface 43 is formed so as to be sandwiched between the curved surfaces 42. Both concave curved surfaces 42 are inclined so as not to be depressed, and are continued to the convex curved surface 43. Then, each edge of the bellows 40 is welded to the inner peripheral surface of the open end 11 of the container body 10 and the surface of the dispersion plate 30 so that no gap is generated between the container body 10 and the dispersion plate 30. It is done.
- a liquid raw material is poured from a part of the lid 20, and the raw material is heated in a high vacuum atmosphere, so that Fat is polymerized.
- the raw material poured from the lid 20 flows down into the container body 10 through the numerous holes 31, 31... Without staying on the concave curved surface 42 of the bellows 40. Therefore, since no stagnant portion of the raw material is generated, the polymerized resin can prevent the gel from being mixed.
- the dispersion plate 30 in the container body 10 is also transferred by heat conduction, retention, and radiation.
- the temperature rise of the disperser 30 is delayed compared to the outward flange 14 that directly transfers heat, and due to the difference in thermal expansion between the outward flange 14 and the disperser 30, there is a gap between both 14 and 30. Change.
- the bellows 40 in which the container body 10 and the dispersion plate 30 are sealed by welding are formed with a concave curved surface 42 and a convex curved surface 43 that are continuous in a wavy shape, and are constrained in the protruding direction of the convex curved surface 43. Therefore, as shown by the two-dot chain line in FIG. 1, the convex curved surface 43 expands so as to slightly protrude. The swollen bellows 40 does not have a recess for retaining the raw material.
- the container body 10, the outward flange 14 and the lid 20 are cooled and contracted.
- the velvet 40 in which the container body 10 and the dispersion plate 30 are sealed by welding, has a concave curved surface 42 and a convex curved surface 43 that are continuous in a wave shape, and is not constrained in the direction opposite to the protruding direction of the convex curved surface 43.
- the convex curved surface 43 is slightly concave and contracts to the concave curved surface without breaking as shown by the one-dot chain line in FIG.
- the bellows 40 thus contracted do not have a dent for retaining the raw material, and it cannot be broken because it contracts to a concave curved surface.
- this pressure vessel can be used as a device for filling each liquid gas and pressurized material, not as a device for polymerizing the resin.
- the pressure vessel can be similarly implemented in a horizontal posture or an inclined posture as well as in a vertical posture.
- the bellows 40 is not limited to the bent portion 41 in which one row of convex curved surfaces 43 is formed between two rows of concave curved surfaces 42 as shown in the figure.
- the convex curved surface 43 can be continuous in a wave shape.
- the pressure vessel sealing structure according to the present invention can be effectively used in a pressure vessel used as a device for polymerizing a resin, or as a device for filling a liquid gas or a pressurized substance. I'll do it.
