Liquid level detection warning and handling device

Abstract

The invention discloses a liquid level detection warning and handling device. The liquid level detection warning and handling device comprises a liquid storage chamber and a detection tube. The liquidstorage chamber is communicated with the detection tube. A handling device, a valve control device, a warning lamp and a loudspeaker are arranged at the top of the liquid storage chamber fixedly. A liquid level tube penetrating the detection tube is fixedly arranged at the inner bottom of the detection tube. A plurality of liquid inlet grooves are formed in the bottom of the side wall of the liquid level tube. A hollow ball is connected to the central position of the inner bottom of the liquid level tube through an elastic rope. A liquid level warning plate is arranged on the outer wall of the liquid storage chamber fixedly. An infrared emitter and an infrared receiver are arranged on two sides of the inner wall of the detection tube symmetrically. The liquid level detection warning and handling device has the advantages that whether or not the liquid level height in a container exceeds a warning height can be detected timely and accurately through a simple structure, and the liquid level height can be controlled automatically; through the detachable detection tube, parts in the detection tube are maintained and replaced conveniently; operation is facilitated, and enterprise production cost is saved greatly.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a liquid level detection, early warning and processing device. Background technique [0002] Liquid level detection devices are widely used, and a large number of equipment need to detect the position of the internal liquid, such as chemical reaction kettles. At present, the technologies used for liquid level detection include float method, ultrasonic reflection method, conductivity method, capacitance method and so on. Among them, the cost of the ultrasonic reflection method is relatively high, and the conductivity method is easily affected by factors such as the dielectric constant of different batches of liquid reagents and the ambient temperature and humidity. The structure of the capacitance method is relatively complicated and the operation is cumbersome. liquid level. However, the float type sensor has a large volume, which is very inconvenient for detection, and the s...
