Chemical engineering sampling equipment for solid-liquid synchronous sampling and sampling method

Abstract

The invention provides chemical engineering sampling equipment for solid-liquid synchronous sampling. The chemical engineering sampling equipment comprises an inner pipe, a spiral pipe arranged on the periphery of the inner pipe in a sleeving manner, and at least two groups of sliding sleeve pieces arranged in the spiral pipe. The sliding sleeve pieces are driven by water flow to slide along the interior of the spiral pipe, a sliding plug is always parallel to the cross section of the spiral pipe, and the sliding sleeve pieces are connected through a second connecting part; a plurality of containing cavities are formed in the bottom of the inner pipe, the containing cavities and the spiral pipe are arranged in a staggered mode, each containing cavity is provided with a contraction-shaped notch, the containing cavities are communicated with the bottom of the inner pipe through the notches, and the containing cavities are detachably connected with the inner pipe; and the inner pipe is further provided with a circulating pump, so that the sample in the inner pipe circularly flows. According to the sampling device for simultaneously sampling the solid and the liquid of chemical raw materials, disclosed by the invention, synchronous sampling of the powdery solid and the liquid can be realized, the sampling steps are simplified, the working hours are shortened, and meanwhile, the accurate control on the solid-liquid ratio can be realized.

Description

technical field [0001] The invention relates to the technical field of process sampling, and more specifically relates to a chemical sampling device and a sampling method for solid-liquid synchronous sampling. Background technique [0002] In the production process of the chemical industry, it is often necessary to regularly sample and detect, track the reaction and the processing process. Although with the advancement of science and technology, many tests can achieve real-time online tracking and detection, but in many special cases, due to the limitations of reaction conditions and equipment conditions , real-time online detection cannot be adopted, and manual sampling is required for analysis and detection. [0003] In the industrial sampling process, the temperature of many chemical samples in the induction process is relatively high or toxic. Although heat-insulated gloves are worn, as the time of holding the thermos bottle increases, the internal temperature of the hea...

AI Technical Summary

Problems solved by technology

One, the effect of the clamping device for industrial sampling disclosed in this prior art is not ideal, and the protection it can achieve is still limited

Second, it only uses two clamping rods for clamping, and the amount of sampling cannot be accurately calculated. At the same time, the degree of sampling has relatively large limitations, and only a small amount of sampling scale is used.

Third, the service life is difficult to measure. Sampling highly corrosive chemical waste liquid and other samples will inevitably damage the clamping device for industrial sampling, which is not suitable for long-term use.

Fourth, it is impossible to sample solid and liquid at the same time
