Abstract

PURPOSE:To simplify a quantitative distributing mechanism of a liquid by dividing the interior of a tank into cells of a constant volume by substantially longitudinal partition walls in a manner that upper parts of said partition walls are communicated with each other and, providing at least one cell with a liquid surface detecting means and each cell with a liquid feeding means. CONSTITUTION:A lower part of an air-tight tank 1 is divided into quantitative distributing cells 10a-10c of a predetermined volume by partition walls 2. A communicating hole 9 is formed in an upper part of each partition wall 2. A liquid leading line 3 is provided in the tank 1 and liquid feed lines 4a-4c are provided in the respective cells 10a-10c. Moreover, a pressure line 5 is provided in the tank 1 to control the pressure within the tank. A liquid surface detecting sensor 7 is placed in a cell most distant from a cell provided with the liquid leading line 3. Accordingly, a large volume of the liquid can be quantitatively distributed in a short time.

That is, the present invention is a tank-type liquid quantitative dispensing device,
A vertical partition wall that makes the upper space inside the tank communicate with each other and divides the lower space into a plurality of cells, a liquid introducing means and a liquid level gauge provided in at least one of the cells, and the liquid level gauge. This is a liquid quantitative dispensing device comprising a liquid feeding means for feeding the liquid in the cell based on a liquid level detection signal obtained by the present invention.

The characteristic requirements of the present invention are that the inside of the tank is divided into cells of a constant volume by substantial vertical partition walls, that the upper part of the partition wall has a communicating structure, and that at least one cell has liquid level detection. Each cell is provided with a liquid feeding means.

80 Effects In the present invention, the inside of the tank is divided into cells of a constant volume by substantially vertical partition walls, and the upper part of the inside of the cell has a communicating structure, so that only one liquid inlet is required. That is, when a liquid is introduced into one cell, the liquid overflows from a communication means such as a communication port in the partition wall or a notch in the partition wall, and accumulates in an adjacent cell for quantitative dispensing. As a result, liquid is uniformly stored up to the cell farthest from the liquid inlet.

Next, in the present invention, since at least one cell is provided with a liquid level detection means, a constant volume is stored in each cell in the tank. That is, when the liquid level becomes slightly higher than the position of the communication means of the partition wall, the liquid level in each cell is kept constant by stopping the liquid supply from the liquid inlet. A preferred position for providing the liquid level detection means is the cell farthest from the liquid inlet. This enables accurate liquid level management.

Next, in the present invention, since each cell is provided with a liquid feeding means, the liquid in each cell is accurately fed. Such liquid feeding means may simply be provided with a discharge port in each cell and connected to a pipe via a valve, or may be connected to a liquid feeding pump. In the case of a valve, the valve may be switched using a common switching valve in the liquid feeding line of each cell.

また槽の上部から圧力をかけて圧送してもよい。Alternatively, pressure may be applied from the top of the tank for pressure feeding.
