Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cylindrical tank whose interior is divided into a plurality of chambers around an axial center.

[0002]

[Prior Art]

 For example, when storing liquids of the same type, such as tempura oil, paints, and printing inks, which have different uses and colors, in a single tank, conventionally, as shown in FIG. 9, for example, a cylindrical multi-chamber type is used. I am using a tank. In this tank, a hollow shaft member 23 is provided in the shaft center portion of the body plate 21 between the end plate 22 at both ends, and a partition wall 24 connected to the body plate 21 at a constant angle from the shaft center member 23. Are attached in a substantially radial direction to form a plurality of storage chambers 25 around the shaft center member 23.

[0003]

[Problems to be solved by the device]

 However, in the above tank, in order to prevent the deformation caused by the difference in the amount of stored liquid between the adjacent storage chambers 25 by providing the partition wall 24 with strength, a circle of radius r with the center as one storage chamber 25 side. It is formed in an arcuate cross section or a corrugated cross section. Therefore, in a tank having a partition wall having an arcuate cross section, the partition wall 24 and the body plate 21 are joined to each other with a considerable inclination angle with respect to the inner surface of the body plate 21, and the welding work is performed on the acute angle β side. There was a problem that welding with high strength and high confidentiality could not be expected due to the lack of space. Therefore, the radius of curvature r of the partition wall 24 cannot be reduced, and it is necessary to increase the plate thickness in order to secure the strength of the partition wall 24. Another problem is that it is difficult to clean the corrugated partition wall.

The present invention solves the above problems and facilitates the joining work with the body plate, the strength of the partition wall can be secured and can be made thin, and the tubular tank having a plurality of chambers can be easily cleaned. The purpose is to provide

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention has a shaft body member at the shaft center portion of a tubular body plate, and a plurality of partition walls connected to the body plate in a substantially radial direction from the shaft body member, In the cylindrical tank with the storage chamber formed, the cross-sectional shape of the partition wall in the plane orthogonal to the shaft center member is changed to an arc shape with the shaft center member side centered on one storage chamber side adjacent to the partition wall side. In addition to the formation, the body plate side is formed in an arc shape centered on the other storage chamber side, and the joint angle of the partition wall to the body plate is set to a substantially right angle.

[0006]

[Action]

 According to the above configuration, since the partition wall is composed of two arcuate cross sections which are opposite to each other, it is possible to secure a strength capable of sufficiently coping with the pressure generated by the uneven distribution of the stored liquid amount in the storage chamber even when the plate thickness is thin, and the body. The joint angle of the bulkhead with respect to the can be set almost at a right angle, and the welding work can be performed with sufficient space secured, and sufficient strength and airtightness can be secured for welding. Moreover, the cleaning work of the partition wall can be easily performed.

【Example】

 An embodiment of a four-chamber cylindrical tank according to the present invention will be described below with reference to FIGS. 1 and 2.

This tank is formed into a cylindrical container shape by a cylindrical body plate 1, a top end plate 2 that closes the upper surface of the body plate 1, and a bottom end plate 3 that closes the bottom part of the body plate 1. The end plate 2 and the bottom end plate 3 are provided with a cylindrical shaft member 4 at the center A of the end plate 3, and four semi-cylindrical auxiliary members 5 are arranged on the inner surface of the body plate 1 at equal intervals in the direction of the shaft center A. Is fixed along the entire height direction. A partition wall 6 is fixed between the axial member 4 and the auxiliary member 5 in a substantially radial direction to divide the inside of the tank into four storage chambers 7. Although not shown, each storage chamber 7 is provided with a supply port and a discharge port for the liquid to be stored.

When the partition wall 6 has a planar cross-sectional shape, it is formed on an inner arc portion 6a having a radius R ₁ and having a center O ₁ on the axial member 4 side as the center O _{1 on one} side of the adjacent storage chamber 7 side. In addition, the body plate 1 side continuous from the inner circular arc portion 6a is formed into an outer circular arc portion 6b having a radius R ₂ with the center O ₂ on the other storage chamber 7 side, and is formed into an overall S shape. ing . Each partition wall 6 has the same shape and is formed point-symmetrically about the axis A, and the joint angle α of the partition wall 6 to the auxiliary member 5 with respect to the body plate 1 is set to a substantially right angle. Again I same der the radius R ₂ of the radius R ₁ and outer arc portion 6b of the inner arc portion 6a, or may be different.

According to the above configuration, since the partition wall 6 is formed in the inner circular arc portion 6a and the outer circular arc portion 6b in an S shape in a plan sectional view, sufficient strength can be obtained and the amount of liquid stored in the storage chamber 7 can be increased. Due to the difference, the pressure applied to the partition wall 6 can be sufficiently dealt with, and the thickness of the partition wall can be reduced. In addition, since the partition wall 6 has an S-shaped cross-section, the partition wall 6 can be joined to the body plate 1 at a substantially right angle, so that both the storage chambers 7 adjacent to each other with the partition wall 6 interposed therebetween have a welding work space. It can be wide enough, and it is possible to secure a sufficient welding work space even on the side that was difficult to perform welding work in the past because it was an acute angle side, and it is possible to perform welding joint with sufficient strength and high airtightness. Further, since the auxiliary member 5 having a semicircular cross section is interposed between the body plate 1 and the partition wall 6, the body plate 1 can be reinforced, and the strength of the tank against a vertical load is greatly increased. be able to.

Although the tank using the curved end plates 2 and 3 is shown in the above embodiment, a conical top plate 12 and a flat bottom plate 13 may be provided as shown in FIG. . Of course, as shown in FIG. 4, a two-chamber cylindrical tank in which the inside of the tank is divided into two storage chambers 7 by two partition walls 6 or the inside of the tank by three partition walls 6 as shown in FIG. It is also effective for a three-chamber cylindrical tank divided into three storage chambers 7 and a six-chamber cylindrical tank in which the inside of the tank is divided into six storage chambers 7 by six partition walls 6 as shown in FIG. Further, as shown in FIG. 7, a four-chamber rectangular cylinder tank in which the inside of the rectangular cylinder body plate 16 is divided by the partition wall 6 may be used. Further, although the semi-cylindrical auxiliary member 5 is interposed between the body plate 1 and the partition wall 6 in each of the above-described embodiments, the partition wall 6 may be directly welded to the inner surface of the body plate 1 as shown in FIG. Good.

[0012]

[Effect of the device]

 As described above, according to the multi-chamber cylindrical tank of the present invention, since the partition wall is formed by the arc portions of the two arc-shaped cross sections whose centers are on opposite sides, the storage chamber is thin even if the plate thickness is thin. It is possible to secure the strength that can sufficiently cope with the pressure generated by uneven distribution of capacity, and the joint angle of the partition wall to the body can be set to almost a right angle, and welding work can be performed with sufficient space. It is possible to secure strength and confidentiality. Moreover, cleaning work can be performed more easily than with a corrugated partition wall.
