Waste liquid liquid-level detection system with failure self-detection function, and detection method

Abstract

The invention relates to a waste liquid liquid-level detection system with a failure self-detection function, and a detection method, and belongs to the technical field of liquid level detection. Thewaste liquid liquid-level detection system comprises a liquid level detection module and two or more than two liquidometer; the liquid level detection module is connected and communicated with the liquidometers; and each liquidometer is used for detecting the full liquid state of a liquid storage box body. The liquid-level detection method comprises the steps of monitoring the liquid level in realtime and performing failure self-detection by the liquid level detection device. According to the waste liquid liquid-level detection system and the waste liquid liquid-level detection method, the plurality of liquidometers are used for detecting the full liquid state of the liquid storage box body, so the liquid level detection failure can be reduced, the liquid-level detection system can be subjected to liquid-level failure detection, the maintenance cycle of the equipment is prolonged and the maintenance cost of the equipment is reduced.

Description

technical field [0001] The invention relates to a waste liquid level detection system and a waste liquid level detection method with a fault self-checking function, belonging to the technical field of liquid level detection. Background technique [0002] Kitchen waste oil is an important recyclable resource in kitchen waste. Kitchen waste oil can be used as a raw material for the production of biodiesel, soap, dish soap, cosmetics and other chemical products. In the process of food waste treatment, when recovering waste oil from food, the food waste is usually separated into solid and liquid first, and then the food solid residue and waste liquid are obtained after separation, and then the waste liquid is separated into solid and liquid to recover the oil in it. Whether it is waste liquid collection in solid-liquid separation or grease collection in oil-water separation, liquid level gauges are used for liquid level monitoring and detection. However, because catering was...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of frequent failures and high equipment maintenance costs of the kitchen waste liquid level detection device in the prior art, and provide a waste liquid level detection system with a fault self-test function. The waste liquid level detection system provides physical component support for the liquid level detection self-inspection of the liquid level detection system. With the corresponding control module, it can self-inspect the liquid level fault of its own liquid level detection system and extend the maintenance cycle of the equipment , reduce equipment maintenance costs
