According to the crystallization reaction device provided by the invention, a dynamic crystallization reaction process or a static crystallization reaction process of the zeolite molecular sieve can be selectively carried out according to requirements; and the quantity of materials added into the reaction box through the material supply box is the required quantity, so that the device is flexible to use.

Description

technical field [0001] The invention belongs to the technical field of synthesis experiments of zeolite molecular sieve, and particularly relates to a dynamic and static dual-purpose crystallization reaction device of zeolite molecular sieve. Background technique [0002] Zeolite molecular sieve is a hydrate of crystalline aluminosilicate metal salt, and it is the only adsorption and catalytic material with shape selectivity. The functional catalytic materials required for production are formed by means such as loading modification, so they are more and more studied and used in many fields, and their use is becoming more and more extensive. [0003] For example, a patent document with publication number CN208574623U discloses a zeolite molecular sieve preparation device, which includes a tank body, a base, a feeding port, a motor and a discharge pipe, and a base is arranged below the tank body. The surface of the base is There is a chute, the tank body is embedded in the ba...

Problems solved by technology

[0006] In the experimental process of the processing and synthesis of zeolite molecular sieve provided by the above scheme, only a single mixing structure is used to perform a single dynamic synthesis of zeolite molecular sieve. This method cannot guarantee the mixing and synthesis effect of zeolite molecular sieve for dynamic mixing and synthesis of zeolite molecular sieve. , in addition, the synthesis experiment process of zeolite molecular sieve is not only dynamic synthesis, but also static synthesis. If the influence of static and dynamic synthesis methods on zeolite molecular sieve is investigated, two sets of synthesis devices are often prepared. Obviously, the synthesis device provided by the above scheme can not achieve
