Problems solved by technology

The initial sampling method was artificial sampling at the top of the tank car. Due to the depth of the tank car, generally only sampling at the surface layer made the sampling unrepresentative and seriously affected the accuracy of physical and chemical index detection; later, sampling tubes were used for sampling. Samples that go deeper into the tank can only be sampled at the top cover, which is also not representative, and the sampling tube adopts a mechanical rotation structure, which has a very high failure rate. It is often necessary to replace the sampling tube after two or three uses, and the sampling tube consumes Many and high cost

Abstract

The invention relates to the technical field of powdery material sampling, in particular to a continuous sampling device for a gas conveying pipeline. The device comprises a gas conveying sample pipeline, a flow guide pipe, a pneumatic stirring pipeline, a material collecting container and a discharge port, the whole gas sample conveying pipeline is obliquely arranged, the flow guide pipe is arranged in the middle of the gas sample conveying pipeline and connected with one side of the upper half portion of a material collecting container, and the pneumatic stirring pipeline is arranged at the top of the material collecting container which is funnel-shaped and provided with the discharge port at the bottom. The invention reduces the consumption of sampling consumables, accurately and controllably collects the sample, improves the test quality of the sample, reduces the cost and improves the sampling efficiency.

Description

technical field [0001] The invention relates to the technical field of powder material sampling, in particular to a continuous sampling device for gas delivery pipelines and an operating method thereof. Background technique [0002] Gas conveying uses the energy of airflow to transport powdery materials along the direction of airflow in a closed pipeline, which is a specific application of fluidization technology. It is widely used in gas transportation. Taking metallurgical quicklime powder in iron and steel plants as an example, quicklime powder for sintering production is transported to the use site by tanker, and directly transported to the quicklime storage bin through gas pipelines for use. The quality of quicklime powder directly affects the sintering production process and product quality, so it is necessary to regularly sample and test relevant physical and chemical indicators, and adjust the lime ratio and production operation according to the test results. To ens...
