Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a split-type powder storage tank that accommodates and stores powder and granular materials such as wheat flour and takes out a predetermined amount of the tank as desired.

(Prior art) Conventionally, tanks for storing powder and granular materials such as wheat flour have been used as described in Japanese Patent Application Laid-Open No. 1986-19560 and Japanese Patent Application Laid-open No. 59-74085.
As shown in the above publication, a storage tank is known in which the interior is divided into a plurality of parts by a partition plate.

In the former, the partition plate is movable to form powder storage chambers, and in the latter, different lots of powder and granular material are stored in each divided chamber,
A certain amount of powder and granules are taken out and mixed at the same time in the lower part.

On the other hand, it has been conventionally desired to take out the powder and granules individually from each divided chamber. However, if there is a difference in the storage amount in each divided chamber, a large stress is applied to the partition plate whose one side is not stored due to the pressure of the powder or granular material on the other side. However, in the two examples of tanks shown above, problems such as deflection and damage of the partition plates occur, making it difficult to meet the above-mentioned request for individual removal. For this reason, as shown in FIGS. 9 and 10, in addition to the partition plate 21 disposed along the axial direction inside the cylindrical tank body 20, there are A large number of reinforcing members 22 are installed horizontally between the partition plate 21 and the tank body 20 at predetermined intervals in the direction.

(Problem that the invention aims to solve) However, in conventional storage tanks equipped with a large number of reinforcing materials, it is necessary to arrange and fix the reinforcing materials in addition to the partition plates, making the construction complicated and reducing the number of parts. There is a problem in that because there are so many, maintenance and management is time-consuming. Furthermore, because partition plates and numerous reinforcing materials are installed inside the tank body, there are many corners at the joints between parts, and powder and granules tend to remain, so in some cases cleaning work to remove them may be necessary. There is also the problem that it requires

The basic purpose of this invention is to solve the above-mentioned problems, and to provide a split-type powder storage tank that is easy to construct and easy to maintain.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a split type powder storage tank in which the cylindrical tank main body is divided into a plurality of parts by partition plates along the axial direction. The board is composed of a corrugated sheet formed in a wave shape along the axial direction, and a flat plate stretched on the front and back surfaces of the corrugated sheet. is characterized in that a corner member is installed to cover the corner.

The corrugated plates constituting the partition plate can have various shapes, such as sine waves, triangular waves,
A waveform having a shape such as a square wave is used. Various methods can be considered for arranging this partition plate on the tank body. For example, it is conceivable that the partition plates are arranged horizontally and vertically, or that a cylindrical or polygonal support is erected at the center of the tank body, and the partition plates are arranged radially around this support. Since corners are created between the members due to the arrangement of these partition plates, corner members are arranged to cover these corners. The corner member is installed between two members forming a corner, and may be any member that covers the corner with a gentle surface, or may have a large corner angle.

(Function) According to this invention, the partition plate can be composed of a plate material prepared in advance, and is arranged so as to have waves along the axial direction of the tank body, so that it can withstand lateral stress.
Sufficient strength can be obtained. Therefore, even if one side of the partition plate does not accommodate powder or granular material, bending, damage, etc. can be prevented. Moreover, since corner members are installed at the corners created by the arrangement of the partition plates, the corners can be configured with gentle surfaces, and it is possible to prevent powder particles from remaining in the corners.

(Example) An example of this invention will be described below based on FIGS. 1 to 8.

A square cylindrical support 2 is erected at the center of a cylindrical tank body 1, and two partition plates 3, 3 are arranged diametrically along the axial direction so as to abut one side of the support 2, respectively. is placed and fixed. Also,
One partition plate 3 is arranged and fixed at right angles to these two partition plates 3, 3 so as to contact the support column 2, and the inside of the tank body 1 is divided into storage chambers 1a, 1b, and 1c. . In addition, discharge pipes 4a, 4b, and 4c whose diameters decrease downward are connected to the lower part of the tank body 1, corresponding to the respective storage chambers 1a, 1b, and 1c, and between each discharge pipe, A frame-shaped reinforcing member 5 is provided.

The partition plate 3 is formed by a corrugated plate 3b having a pulse wave shape having square portions 3a at predetermined intervals along the axial direction of the tank body 1, and flat plates 3c, 3c stretched on the front and back sides of the corrugated plate 3b. Furthermore, the four side edges of the partition plate 3 are formed of square pipes 3d. These partition plates 3 are stacked vertically in three stages to partition the inside of the tank body 1 into three parts. Further, elongated corner members 8 are disposed along the axial direction at corner portions 6 formed by the partition plates 3 and corners 7 formed by the side edges of the partition plates 3 and the inner wall of the tank body 1. The corner portion 6 and the corner portion 7 are covered.
Note that the upper end of the tank body 1 is covered with a lid 10, and in the center of the lid 10 are each storage chamber 1a, 1b,
An input port 11 communicating with 1c is formed.

Next, how to use this tank will be explained below.
Powder and granular materials such as wheat flour of different grades are charged into each storage chamber 1a, 1b, and 1c from an input port 11 and stored. On the other hand, when taking out the desired granular material from this tank, the granular material is taken out from the storage chambers 1a, 1b, 1c through at least one of the discharge tubes 4a, 4b, 4c. By taking out the powder and granular materials individually from each storage chamber in this way, differences occur in the amounts stored in the storage chambers. For this reason, a powder storage portion and an unaccommodated portion are created on both sides of the partition plate 3, and stress is applied to the partition plate 3 toward the unaccommodated portion due to the pressure of the powder. However, as described above, the middle plate of the partition plate 3 is composed of a corrugated plate 3a, and has sufficient strength to withstand the above-mentioned stress. Furthermore, corner members 8 are installed over the corners 6 and 7, and the corners are closed with smooth surfaces, thereby preventing powder particles from remaining in the corners.

In the above embodiment, the partition plate 3 was arranged along the radial direction of the tank body 1, but as shown in FIG.
2 may be erected and a plurality of partition plates 3 may be arranged radially so as to contact the outer surfaces of the support columns 12, respectively. In this case, corner members 8 are arranged and fixed at the corners as in the previous embodiment.

The point is that the partition plate may be arranged along the axial direction of the tank body, and the arrangement method is not particularly limited.

Further, in the above embodiment, the corrugated plate 13 has a pulse wave shape, but as shown in FIGS.
It is also possible to construct a partition plate by using corrugated plates a, 13b, or 13c and extending flat plates 14 on the front and back surfaces of these corrugated plates.

(Effects of the invention) As explained above, according to this invention, in a storage tank in which the cylindrical tank main body is divided into a plurality of parts by a partition plate along the axial direction, the partition plate has a wavy shape along the axial direction. It is composed of a corrugated plate formed on the top and a flat plate stretched on the front and back sides of the corrugated plate, and a corner member that spans between the two members is placed at the corner that is created when this partition plate is joined to the partition plate or another member. Since the structure is constructed, the strength of the partition plate in the lateral direction is improved, and powder and granular materials can be taken out individually from the divided storage chambers. In addition, a corner member is installed at the corner portion, and there is no protrusion of reinforcing material or the like in the flour crushing portion, which has the effect of preventing residual powder and granules and facilitating maintenance and food hygiene management.
