Abstract

PURPOSE:To reduce a space for a jacket of a container to a large extent as compared to a conventional type and to enhance heat exchange efficiency, by forming an expansion coupling structural part to the outer wall of the jacket. CONSTITUTION:The upper jacket of a jacketted container 1 is fixedly mounted to the upper periphery of the container through a strip metal 3 and an expansion coupling structural part 5 is formed to the intermediate peripheral part thereof. Because the thermal change of the jacket 4 can be absorbed by said structural part 5 in this structure, the thickness of the strip metal 3, therefore, the space for the jacket S can be extremely reduced as compared to a conventional structure. On the other hand, the upper end of a bottom jacket 15 is welded to the side surface of the container 1 through the strip metal 3 while the lower leading end part thereof reaching the vicinity of the central part of the bottom surface of the container 1 in a curved form is connected to the bottom surface of the container in a state forming a coupling structural part 5' curved in a U-shape. This structural part 5' absorbs the thermal change of the jacket wall similarly to the aforementioned structural part 5.

Description

[Detailed description of the invention] At the end of the main activity (b), there was no fever in the stomach due to partial reaction.

The jacketed culm KQ is capable of cooling and simultaneous heating and cooling of specific areas.

In conventional jacketed containers, the outer wall of the container 4 is attached to the outer wall of the container 4 by bending the end portion of the jacket, which serves as the closing connection of the jacket to the main body of the container, with a length of 1 m or so. This bending +70L allows thermal elongation during heating or cold KJ4 operation of the jacket to reduce the elasticity of the above-mentioned curved end! 'It is done to absorb by form. The radius of curvature of this curvature cannot be made smaller than a certain limit because it is directly affected by the longitudinal elastic modulus of the jacket members. Therefore, as the plate thickness of the jacket of the main body of the main body of the large volume 4 becomes large, the radius of curvature of the jacket becomes large and the width of the gap between the jackets also becomes thick. When the jacket's gap volume increases, a large amount of heat medium is required, and therefore not only a large heat loss occurs when switching between zero heating and cooling, but also a long response time. Also, the jet surface area of the jacket becomes larger Ic, so the flow velocity of the heat medium becomes slower.
Another problem is that a pump with a large flow pupil is required as a countermeasure to the problem that the heat transfer efficiency decreases due to thicker parts that contact the outer wall of the container body. For the purpose of increasing heating medium speed.

A model with a small pitch ripple-shaped guide has been proposed, but due to the 111 design, there is a connection between the outer q surface of the 44 main body and the guide, so the guide #-i can fully demonstrate the flow guiding function. Can not. Therefore, the culm with a small jacket gap is l! ? has been done.

The present invention was devised to overcome the above la.
Expansion joint structure in which the ICIIIJ bending process of the jacket end is ovalized as in the past, the ram end is closed with an annular band and fixed to the fA base body, and the thermal deformation of the jacket wall is formed in cough #1. It is characterized by being absorbed by.

The horizontal expansion joints mentioned above can be of P type or Omega type if they are made of materials that have the required warm elasticity and are resistant to corrosion.

It may be of the shape root type, plural type 1 type, U type, number U type, J type, octagonal J type, etc. root type.

Furthermore, in one embodiment of Akira Motonuma, the movement of the heat medium in the expansion part of the @hand structure is prevented by providing a cylindrical plate that slides into contact with the inner surface of the leg of the coffin skewer by extension due to the heating film. , # Since the expansion gk portion absorbs only the expansion and contraction due to thermal stress, it has the advantage of reducing heat loss and making electrical adjustments in a relatively short time.

The beak can be made of any material having the required precision and corrosion resistance, such as iron, stainless steel, titanium, aluminum, zirconium, or alloys thereof.

To summarize the advantages obtained by the present invention: 111
Since the amount of heat medium held in the jacket is not 'P', the ambiguity of the mixed sweetener for alt adjustment is smaller than that of the conventional 4 with the same content, and the heat loss is also small: +21 M concentration, af# luxury when the temperature drops. (4) The installation speed and driving arm of all electric power units are reduced. These are the 7 things that can meet the objectives of resource exploration and energy conservation as much as possible.

The invention will now be described in conjunction with Drawing II 5'' showing an embodiment fl+ with a pendant joint beak part.

As shown in the second section, which is an enlarged view of area A in FIG. Since thermal expansion and contraction of the jacket is absorbed by the deformation represented by the change in radius R, the jacket gap S (RIC"J in the illustrated embodiment) should be less than a constant degree.

FIG. 5 shows an enlarged view of the bottom area C of FIG.

As shown in the figure, the upper end of the bottom jacket 15 is welded to the first side of the container 41 via the strap 3, and the lower tip that curves and reaches near the center of the bottom of the container has a U-shaped joint structure.
' and is connected to the bottom of the container. This 44a section 5'
absorbs thermal expansion of the jacket wall in the same way as structure 65 described above.

FIG. 6 shows a modified leprosy example of the present invention. In this embodiment, the upper end of the closed cylindrical plate 6 is attached to the expansion joint structure part 1ii with a groove contact 16, so that the inner cylindrical plate 60F end is It sticks out to the tip of one leg. When the jacket contracts due to heat contraction, the tip of the cylindrical plate of the expanded leg slides into contact with the inner surface of the other leg next to the joint, and the 1M space 18 becomes 1'! 3. Maintain a sense of admiration. This cylindrical plate 5 may be made of a thin material, and the jacket 1 & 1lF
4 has almost no effect. This cylindrical plate has a diameter of 2 to 5 mm, with the expansion line closed during the initial period or for the purpose of a small amount of heat medium circulation. Generally, one or more small holes 19 are made. This small amount ft4 is used to slowly generate a warm, flat flow during switching between heating and cooling, and almost no latent flow is generated within the space 18. Since heat exchange takes place slowly, operational efficiency can be increased.

Furthermore, as an example of a special use of the apparatus of the present invention in which heating and cooling are performed at the same time, an explanation will be given of the cleaning operation of machinery and articles using the solvent trifluorethylene. This solvent is often used for cleaning mechanical parts, but since the specific gravity of this vapor is about 453 (1:1), it does not mix well with air and is nonflammable. In the case of the above-mentioned washing operation, 4 parts of wax of this solvent is charged into the g* bottom, and when it is heated in the bottom jacket, bran is generated and filled into the tank.

? At the same time, when cooled in the upper jacket, the solvent vapor turns into mist, which adheres to the mechanical parts placed inside the container, dissolves cutting oil, etc., and falls as droplets to the bottom of the container, allowing efficient cleaning.

The device 1 of the present invention is also suitable for heating and saponifying higher alcohols with alkaline compounds [(1!). When using 1 cta of higher alcohol soap, foaming occurs as the saponification progresses and foaming continues for 1 time. Overflowing from the container a
The continuation operation becomes internal.

When the present invention@electronic device is used once and is cooled in the upper jacket during the above operations, the bubbles are contained by cooling the water vapor within the bubbles, thereby preventing the bubbles from flowing out.

As mentioned above, the culm 4 of the present invention can significantly reduce the jacket cabinet size compared to the conventional type, and also has the effect of increasing heat exchange efficiency and meeting the objectives of cost and energy conservation. It is.
