Description

Technical Field

[0001] The utility model relates to the technical field of catalyst sampling, and more specifically to an automatic catalyst sampling system. Background Art

[0002] The iron-based catalyst for Fischer-Tropsch synthesis is mainly prepared through precipitation reaction, impregnation reaction, spray drying, calcination molding, screening and other processes. After calcination, the catalyst is cooled to 100°C in a cooler and then transported to the screening system. After sampling, the finished product is packaged. During the sampling process of the catalyst, it is necessary to first load the material with a barrel and then sample it with a sampler. At present, 12-15 barrels are required for sampling and analysis every day during loading and taking materials; and each time sampling is performed, it is necessary to climb up, close the valve that sends the catalyst to the tank truck, and open the sampling valve of the sampling barrel. The existing method of loading and taking materials is cumbersome to operate, and requires personnel to climb back and forth to operate, which is time-consuming and labor-intensive, and the personnel operation process is highly dangerous.
