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

Embodiment 1

[0034] Such as figure 1 , image 3 As shown, the waste liquid level detection system with fault self-checking function of embodiment 1 includes a CPU control module, a fault alarm system and a liquid level detection system, and the liquid level detection system includes a liquid level detection module, a liquid level gauge-2 and The liquid level gauge 2 3 , the liquid level gauge 1 2 and the liquid level gauge 2 3 are respectively connected and communicated with the liquid level detection module. The liquid level detection module is connected with the CPU control module, and the CPU control module is connected with the fault alarm system. Liquid level gauge 1 2 and liquid level gauge 2 3 are duckbill float level switches. The liquid level gauge 1 2 and the liquid level gauge 2 3 are installed at the same level in the liquid storage tank 1 . Such as figure 1 As shown, the duckbill float liquid level switch includes a stator 4 and a float 5 , the stator 4 is fixed on the inn...

Embodiment 2

[0037] The waste liquid level detection method with fault self-diagnosis function of embodiment 2 is based on the waste liquid liquid level detection system with fault self-diagnosis function of embodiment 1. Such as Figure 4 , the waste liquid level detection method with fault self-checking function of embodiment 2, comprises the following steps:

[0038] 1. In the liquid level detection module, the liquid level detection fault record is initialized:

[0039] (1) Establish and initialize the number of times N of liquid level detection fault records, record N=0; then enter step (2),

[0040] 2. The liquid level detection system monitors the liquid level in the liquid storage tank in real time:

[0041] (2) Liquid level real-time monitoring: Liquid level gauge 1 and liquid level gauge 2 respectively monitor the liquid full state in the liquid storage tank in real time; when liquid level gauge 1 and / or liquid level gauge 2 detect a liquid full signal, the liquid level gauge ...

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...
