Technical Field

[0001] The utility model relates to the technical field of deuterated methanol preparation, in particular to a continuous catalytic reaction device for preparing deuterated methanol. Background Art

[0002] Deuterated methanol is mainly used as nuclear magnetic resonance reagent, pharmaceutical and synthesis, photoelectric material modification, laboratory special reagent, chemicals, scientific research, detection, etc. Deuterated methanol is an important chemical raw material and deuterated drug intermediate. In chemical synthesis, it is a commonly used nuclear magnetic resonance hydrogen spectrum detection reagent and is widely used in experimental research.

[0003] Existing catalytic reaction equipment usually requires manual addition of raw materials into the equipment after completing the catalytic work of deuterated methanol, so as to perform secondary catalytic work. This method makes the catalytic work operation cumbersome and cannot be carried out continuously. At the same time, the manual addition operation wastes time and affects the preparation speed. In view of this, we propose a continuous catalytic reaction equipment for the preparation of deuterated methanol. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a continuous catalytic reaction equipment for preparing deuterated methanol to solve the technical problems that the raw materials required for the current preparation need to be added manually, resulting in a waste of time and inability to carry out continuous catalytic preparation.

[0006] Preferably, the blocking member includes a guide plate, and the guide plate is obliquely inserted into the lower material bin, and a push plate is fixedly provided on the side end of the guide plate located outside the lower material bin, and a limit plate with a strip-shaped oblique groove is provided on the side of the push plate close to the electric push rod.

[0007] Preferably, movable grooves corresponding to the guide plates are provided on the left and right plate walls of the lower material bin, and the movable grooves are in a diamond shape.

[0009] Preferably, the plate wall of the guide plate and the inner wall surface of the lower silo are both smooth surfaces.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. The utility model can conveniently put the raw materials into the discharge bin in a quantitative manner through the cooperation of the storage bin, the solenoid valve and the discharge pipe. The position of the raw materials can be limited under the restriction of the blocking parts. When the reaction equipment completes the catalytic preparation, the blocking parts on both sides can be moved outward by the electric push rod, so that the raw materials can flow down from the opening position between the blocking parts into the reaction device, thereby greatly improving the effect of automatic feeding. Through such structural cooperation, the operation steps of manual feeding can be omitted, the time required for feeding can be omitted, and the effect of continuous catalysis can be achieved.

[0012] 2. The movement of the blocking piece can be controlled by the electric push rod. During the movement, the coordination of the circular block and the strip bevel can achieve a dislocation effect. The position of the connection between the electric push rod and the blocking piece can be adjusted without affecting the pushing operation. The inclined guide plate can facilitate the rapid unloading of raw materials, avoid dead angles, and facilitate unloading work. BRIEF DESCRIPTION OF THE DRAWINGS
