Description

Technical Field

[0001] This invention relates to the field of preparation vessel technology, specifically to a preparation vessel for catalyst production and its operating method. Background Technology

[0002] A catalyst production preparation vessel is a piece of equipment specifically designed for catalyst production, also known as a reaction vessel, which serves to heat, cool, and mix catalysts.

[0003] For example, the Chinese authorized patent with announcement number CN221131898U (a preparation vessel for catalyst production) includes a preparation vessel body. A rotating shaft is rotatably mounted within the preparation vessel body. A mounting box, connected and communicating with the preparation vessel body, is fixedly mounted on the top wall of the preparation vessel body. A heating wire is installed inside the mounting box. An air pump, connected and communicating with the mounting box, is mounted on the top wall of the preparation vessel body and located on one side of the mounting box. A temperature controller, electrically connected to the heating wire, is mounted on the side wall of the preparation vessel body. A temperature measuring instrument for detecting the temperature of the reaction solvent within the preparation vessel body is installed. This structure allows for better heating and regulation of the reaction reagents within the preparation vessel body, thereby improving the preparation efficiency for catalyst production and increasing the yield of the catalyst obtained from the reaction.

[0004] Most existing preparation vessel shells are one-piece, which makes height adjustment inconvenient. When producing small quantities of catalyst in the same preparation vessel, large cavities will appear. When heating, the heat range is large, resulting in serious resource waste. When producing large quantities, batch production is required, which reduces flexibility and processing efficiency. Therefore, we provide a preparation vessel for catalyst production and its working method. Summary of the Invention

[0015] Preferably, a method for operating a preparation vessel for catalyst production includes the following steps:

[0016] Step 1: Place the adjustment components on the top of the first heating jacket. When placing them, insert the first drain socket into the first drain inlet. Wrap the outer wall of the first drain socket with a sealing strip. Add the number of adjustment components according to the amount of catalyst, and stack them up and down in the same way.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] (1) This invention sets a top component and an adjustment component between the first heating jacket and the stirring component. The adjustment component is added and reduced according to the amount of catalyst. When the amount of catalyst is large, the adjustment component is added; when the amount of catalyst is small, the adjustment component is reduced. The adjustment component is placed on the top of the first heating jacket. The number of adjustment components is added according to the amount of catalyst. The components are stacked and connected in the same way. The first heating jacket, the second heating jacket and the third heating jacket are interconnected through the water channel to facilitate water flow. Modular addition is achieved, avoiding the use of a large space for the production and heating of a small amount of catalyst, avoiding waste of resources and energy, achieving energy saving effect, improving flexibility and energy efficiency. It solves the problems that most existing configuration vessel shells are of one-piece form, which is inconvenient for height adjustment. When the same configuration vessel produces a small amount of catalyst, a large cavity will appear. When heating, the heat range is large, which leads to serious waste of resources. When the amount is large, batch production is required, resulting in low flexibility and processing efficiency.

[0023] (2) By setting a first drain socket on the lower surface of the second heating jacket and a second drain socket on the lower surface of the third heating jacket, when installing the adjustment component, the first drain socket is inserted into the first drain inlet, and when installing the top component, the second drain socket is inserted into the second drain inlet. The outer walls of the first and second drain sockets are wrapped with sealing strips to improve the sealing of the connection between the first and second drain sockets and prevent water leakage. In addition, the limiting effect formed by the first and second drain sockets being inserted into the first and second drain inlets respectively improves the stability of the adjustment component and the top component, making them less prone to shaking and displacement, and thus less prone to loosening and slipping, thereby improving production stability.

[0024] (3) By setting a connecting sleeve outside the rotating column, the connecting sleeve moves up and down along the rotating column through the adjustment groove and is adjusted according to the distance between the first and third reactor bodies. After adjustment, one end of the fastener passes through the positioning slot and the adjustment slot and is fixed by an external nut. The adjustment method is suitable for adding different numbers of adjustment components, improving applicability and flexibility. Attached Figure Description
