Problems solved by technology
[0003] In the existing technology, most of the methods of placing a set of testing equipment in each liquid tank are not able to report and present the data in a timely manner, requiring production technicians to inspect and check. The disadvantages of this method are:
[0004] 1. The number of testing equipment is large, and the investment cost of equipment is high;
[0005] 2. Obtaining test results depends on manual inspection, which is time-consuming and error-prone;
[0006] 3. Chemical enterprise workshops usually have a complex environment, with air pollution, noise, safety hazards, etc., and it is easy to threaten the health and safety of personnel during the inspection process

The invention provides a device for automatic online multipath detection of liquid parameters. The device comprises a liquid detection area, a multipath liquid acquisition pipeline, and a main controlboard, wherein a cleaning water pump and a vacuum pump are connected with the top of the liquid detection area, and are controlled by the main control board to pump or extract a relevant liquid or gas; the bottom of the liquid detection area is connected with the multipath liquid acquisition pipeline through a pipeline; a solenoid valve is arranged at each pipeline water outlet of the multipath liquid acquisition pipeline, and the solenoid valves are controlled by the main control board to be communicated with pipelines of different liquids to be detected; a first liquid level sensor and a liquid detector are further connected between the main control board and the liquid detection area; the liquid amount in the liquid detection area is controlled by the main control board according to liquid level information of the first liquid level sensor; and the liquid parameters are detected by the liquid detector and uploaded by the main control board to an upper computer. The device providedby the invention has the advantages that circular detection of the multipath liquids can be automatically controlled, and detection results can be uploaded online, so that manpower and material resource consumptions are reduced.
Description
technical field [0001] The invention belongs to the technical field of liquid detection, and in particular relates to a device and method for automatic online multi-channel detection of liquid parameters. Background technique [0002] Liquid detection and control is the daily production work of chemical enterprises. It is necessary to detect the necessary parameters of the liquid used in the production process, so as to adjust and control the composition ratio of the liquid in time to ensure the product yield. [0003] In the existing technology, most of the methods of placing a set of testing equipment in each liquid tank are not able to report and present the data in a timely manner, requiring production technicians to inspect and check. The disadvantages of this method are: [0004] 1. The number of testing equipment is large, and the investment cost of equipment is high; [0005] 2. Obtaining test results depends on manual inspection, which is time-consuming and error-p...
