Description

Equipment for accurately adjusting chemical product proportioning and configuration method thereof

Technical Field

Background

In the production process of the chemical field, the processes of sampling detection, reaction tracking and processing are often required to be regularly carried out, although with the progress of science and technology, a lot of detections can realize real-time online tracking detection, under a lot of special conditions, due to the limitation of reaction conditions and equipment conditions, real-time online detection cannot be adopted, and manual sampling is required for analysis and detection.

In the industrial sampling process, the temperature of chemical samples in the sensing process is high or toxicity exists, although the heat-insulating gloves are worn, the hands of sampling workers are easily scalded due to the temperature accumulation inside the heat-insulating gloves along with the increase of the time for holding the thermos bottle; in some cases, steam needs to be taken, the steam temperature is high, the impact force is high, the bottle body is cracked, and sampling personnel are injured; if the body of sampling bottle is stained with when more feed liquid, the sampling bottle is more smooth, and the staff's hand landing is followed easily to influence the sample process, consequently design a clamping device for industrial sampling, the convenient sample process that can be very big improves work efficiency, improves the current situation of work.

The traditional industrial sampling can be a colorless hard glass bottle with a plug or a polyethylene bottle with a plug or a water bucket. In addition, the disposable suction head is widely applied to chemical industry detection equipment, the traditional suction head sampling equipment also realizes the function of automatic sampling, but at present, the simple sampling of liquid can only be realized, the sampling of gas can not be realized, and substances detected by the chemical industry do not contain liquid and gas, so a device is needed to realize both the liquid sampling and the gas sampling, but the sampling mode is limited greatly and has small application range, such as samples harmful to human bodies, such as high heat, high corrosivity and high pollution, the samples are difficult to be extracted by workers by adopting a proper and safe method, for example, if the industrial hot water is improperly operated in the water taking process, the danger of scalding the human body is easy to occur, the sampling of deep water is inconvenient, because the hot sewage generated by the conventional tool is only the hot water positioned in a shallow layer, and the water which can not reach the middle layer or even a deep layer can not be sampled, inconvenience is brought to sampling of industrial hot sewage. Meanwhile, the control on the amount of the extracted sample is difficult to achieve accurately, the problems of too much extraction or too little extraction and the like often occur, and the accurate control on the amount of the sampled sample cannot be achieved.
