Problems solved by technology

[0002] In some chemical reactions, it is necessary to provide the reactor with a given volume of reaction liquid in stages, but this is difficult to achieve in actual operation; in addition, in the process of liquid discharge of reaction liquid, the conventional double-pipe liquid method cannot The gas in the lower container is discharged, which will cause a pressure difference between the upper and lower containers, that is, the liquid cannot be stabilized

Abstract

The invention provides a quantifying liquid-discharging structure with a middle exhaust pipe, which ensures the constant volume of discharging liquid each time, i.e. is capable of stably discharging liquid in a quantifying way. The quantifying liquid-discharging structure comprises a solution tank, a quantifying tank as well as a fluid-discharge pipe and an air inlet pipe below the quantifying tank. The quantifying liquid-discharging structure is characterized in that the bottom of the solution tank is communicated with the top of the quantifying tank below the solution tank through the two middle liquid pipelines, middle electromagnetic valves are respectively installed in the two middle liquid pipelines, the fluid-discharge pipe and the air inlet pipe are respectively installed at the bottom of the quantifying tank, lower electromagnetic valves are respectively installed in the fluid-discharge pipe and the air inlet pipe, one end of the middle exhaust pipe is communicated with one of the two middle liquid pipelines, the other end of the middle exhaust pipe is communicated with the upper part of the solution tank, the middle electromagnetic valves are opened and closed at the same time, the lower electromagnetic valves are opened and closed at the same time, and the middle electromagnetic valves and the lower electromagnetic valves are opened and closed at different times.

Description

technical field [0001] The present invention relates to the technical field of the structure of quantitative feeding, in particular to the quantitative feeding structure with an intermediate exhaust pipe. Background technique [0002] In some chemical reactions, it is necessary to provide the reactor with a given volume of reaction liquid in stages, but this is difficult to achieve in actual operation; in addition, in the process of liquid discharge of reaction liquid, the conventional double-pipe liquid method cannot The gas in the lower container is discharged, which will cause a pressure difference between the upper and lower containers, that is, the liquid cannot be stabilized. Contents of the invention [0003] In view of the above problems, the present invention provides a quantitative feeding structure with an intermediate exhaust pipe, which ensures that the volume of each feeding is constant, that is, it can stably quantitatively feeding. [0004] The technical s...
