Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a tank for dissimilar fluids that separates and simultaneously accommodates and stores different fluids (liquids or gases) within the tank.

(Prior art, problems) Practical tanks that store liquids or gases usually store one type of fluid (liquid or gas), but two or more types of fluids can be stored in a single tank. When housing and storing the fluids separately, a fixed partition wall is placed inside the tank and multiple compartments are provided within the same tank. When the tank is discharged, there are problems such as an increase in the space ratio within the tank, a significant drop in volumetric efficiency, and a large load being placed on fixed partition walls and the like.

A different fluid tank has also been proposed in which a movable compartment wall is provided in the tank so that the volume of the compartment can be increased or decreased, and different fluids are separated and accommodated and stored. However, there are technical problems in the sealing mechanism between the two partitioned storage chambers for moving the partition wall and the movement mechanism of the partition wall, and there are practical problems.

(Objective of the Invention, Means for Solving the Problems) The present invention was developed to solve the above-mentioned problems, and includes a movable separator plate with a float disposed in a tank and a movable separator plate disposed in a tank. A closed area that can be expanded and contracted by an expandable wall body connected to a plate is provided, and a storage chamber for a different type of fluid is provided inside and outside the closed area in the tank, and a storage chamber for a different type of fluid is provided in both storage chambers. It is characterized by a configuration in which all the supply and discharge lines are connected, and an operating cable is connected to the movable separation plate, and the tank is expanded and contracted by a movable separation plate with a float and an expandable wall body connected to the movable separation plate. By forming a closed region in which the separation sealing performance and expansion/contraction performance are improved, a dissimilar fluid storage chamber with variable volume ratio is provided in the tank, and furthermore, all floats and operating cables are connected to the movable separation plate. Accordingly, it is an object of the present invention to provide a tank for different types of fluids, which improves the supply and discharge performance of different types of fluids and solves the above-mentioned problems.

In addition, in the above embodiment, the case where two types of fluids are accommodated is explained. can also be made into a sentence structure.

(Function) The embodiment of the present invention has the above-mentioned configuration, and different fluids, that is, the lower fluid (α) and the upper fluid (h') are not accommodated in the accommodation chambers (α) and (b). Time is the operating cable (9)
Due to the relaxation of the telescopic wall (5), the movable separation plate (44) with a float is lowered by its own weight to the position indicated by the chain line and is held by the support plate (2), and the float (41) is placed on the movable separation plate (4). The float aω is placed through the metal, and the lower fluid (OL') is supplied from the supply/discharge line (6α) into the accommodation chamber (α) by an appropriate mechanism, and the air is bleed using the air bleed pipe (161). As a result, the lower fluid (α
') can be supplied and accommodated, and as the storage capacity increases, the movable separation plate (3) rises and can be freely adjusted to the desired amount. In addition, when all the gas is contained in the storage chamber (α), the air in the storage chamber (α) is evacuated in advance using the air vent pipe αG to create a negative pressure, so that the gas, that is, the lower fluid (α′) is removed. The replacement and supply of products can be facilitated.

The upper fluid (b') can be supplied and stored in the accommodation chamber (b) from the t1 supply/discharge line (6b) via the flexible tube (8) or via the supply/discharge line (26b). The float (1G) rises depending on the supply amount of the upper layer fluid, and the storage capacity is freely adjusted, and the upper layer fluid (b') is smoothly drawn into the storage chamber (b) by removing air with the air bleed pipe (l13). can be supplied to

The lower fluid (α') and the upper fluid (h') can be independently and smoothly discharged by reverse action.
