Phenylhydrazine measuring tank automatic control feeding device

Abstract

The invention discloses a phenylhydrazine measuring tank automatic control feeding device which comprises a feeding control valve, a cut-off valve, pressure sensors and a phenylhydrazine measuring tank. The device is characterized in that the phenylhydrazine measuring tank is installed on a support, the pressure sensors are installed on the periphery of the phenylhydrazine measuring tank in four directions, the lower ends of the pressure sensors are installed on the support, the cut-off valve is installed on a feeding pipe at the upper end of the phenylhydrazine measuring tank, and the feedingcontrol valve is installed on a pipeline at the outer end of the cut-off valve. The phenylhydrazine measuring tank automatic control feeding device is controlled by a program control box to operate.The device has the advantages that the pressure sensors are designed so as to automatically weigh the phenylhydrazine measuring tank at any time, the feeding amount of the feeding control valve and on-off of the cut-off valve are automatically controlled through the program control box, full-automatic work is achieved, manual work is not needed, operation is safe and reliable, and production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of phenylhydrazine metering tank feeding, in particular to an automatic control feeding device for a phenylhydrazine metering tank. Background technique [0002] In the past, when feeding the phenylhydrazine metering tank, the feeding was manually observed by the liquid level gauge. The feeding device below should also be weighed while feeding. When the set liquid level is reached, the feeding will be stopped, and the liquid level will start when the liquid level drops to a certain level. For feeding, this operation requires the staff to keep observing and cannot do other things. If you forget to observe, it will lead to untimely feeding, or too much feeding, operation errors, and great losses to production. This operation consumes too much manpower, is prone to accidents and reduces production efficiency. SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the present invention proposes an auto...

Problems solved by technology

[0002] In the past, when the phenylhydrazine metering tank was fed, it was manually observed and fed through the liquid level gauge, and the feeding device below was also weighed while feeding. When the set liquid level was reached, the feeding was stopped, and the liquid level dropped to a certain level. Feeding, this kind of operation requires the staff to observe continuously and cannot do other things. If you forget to observe, it will lead to untimely feeding, or too much feeding, and operation errors will cause great losses to production.

This operation consumes too much manpower, which is prone to accidents and reduces production efficiency.
