Description

Technical Field

[0001] The utility model relates to the technical field of catalyst production, in particular to a drying device used for catalyst production. Background Art

[0002] A substance that can change (speed up or slow down) the chemical reaction rate of other substances in a chemical reaction, while its own quality and chemical properties do not change before and after the reaction (will change during the reaction), is called a catalyst, also known as a catalyst. Its physical properties may change. Catalysts are widely used in chemical production. With the continuous expansion of the scale of chemical production, the demand for catalysts is also gradually increasing. When producing catalysts, it is usually necessary to extract and extract the drying agent from the liquid. Therefore, drying is a commonly used method in the catalyst preparation industry. The drying conditions and degree of drying of the catalyst have a great influence on the performance of the catalyst.

[0003] When drying the catalyst, the existing drying device for catalyst production usually places the catalyst in a dry and stirrable storage tank. While the catalyst is thermally dried, the catalyst inside is continuously stirred by a stirring shaft to dry it. However, after the existing device has completed drying the catalyst, it is necessary to pause the operation of the device, and then discharge and collect the dried catalyst to dry the next part of the catalyst, which makes the drying efficiency of the catalyst very low. The drying device for traditional catalyst production is large in size and inconvenient to move. During the collective drying process of the catalyst, the catalyst accumulates at the bottom and is not dried sufficiently just by breaking it up with a stirring shaft. For this reason, we propose a drying device for catalyst production. Utility Model Content
