Liquid level control device and chemical equipment

Abstract

The invention relates to the technical field of chemical equipment, and provides a liquid level control device and chemical equipment. The liquid level control device is installed on a container to bemeasured and comprises an auxiliary container and a first communicating pipeline; the auxiliary container is connected with a gravity detection piece used for measuring the gravity of the auxiliary container; two ends of the first communicating pipeline are respectively a first end and a second end; the first end is used for being communicated with the container to be measured, the first end is lower than or equal to the liquid level to be measured of the container to be measured; and the second end is communicated with the auxiliary container. With the liquid level control device adopted, the problems of measurement failure, sensor corrosion damage and other faults frequently occurring in high-salinity wastewater and chemical engineering occasions where crystallization and corrosive materials are likely to occur can be solved. The liquid level control device is an external device of the container to be measured, accurate check of the liquid level of the container to be measured can be ensured, and the realization of high-difficulty liquid level control can be facilitated. The liquid level control device is low in relative cost, is convenient to install, convenient to maintain andimproves the safety of equipment.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a liquid level control device and chemical equipment. Background technique [0002] In the use of equipment in the chemical industry, liquid level display and high and low liquid level control devices are often used. Usually, liquid level sensors, magnetic flap liquid level gauges and other measuring instruments are used. The price and cost are high, and they are used in high-salt wastewater, In the chemical industry where crystallization and corrosive materials are prone to occur, faults such as measurement failure and sensor corrosion damage often occur. Once a fault occurs, safety accidents are likely to occur if it cannot be found in time, and the replacement cost is expensive. The failure of the liquid level measuring instrument will cause the solution to overflow the equipment. A sealed device can cause a sharp rise in internal pressure, which can even cause the ...
