Reaction kettle for producing medical intermediates

Abstract

The invention relates to a reaction kettle for producing medical intermediates. The reaction kettle comprises a tank body, a stretchable rod is arranged in the tank body, and a stop block is arranged at the lower end of the stretchable rod. A feeding annular pipe is arranged at the upper portion in the tank body, the stretchable rod is located in the middle of the annular space of the feeding annular pipe, a feeding inlet is formed in one side of the feeding annular pipe, the pipe wall of the feeding annular pipe is provided with a plurality of spraying openings and a plurality of inclined baffles, the spraying openings correspond to the inclined baffles in a one-to-one mode, and the inclined baffles are downwards inclined. The stretchable rod is sleeved with a magnetic stirrer, the magnetic stirrer is horizontally arranged and located above the stop block, a first electromagnet is arranged on one side of the inner wall of the tank body, a second electromagnet is arranged on the other side of the inner wall of the tank body, the magnetic poles of the first electromagnet and the second electromagnet are opposite, and the first electromagnet and the second electromagnet are controlled through alternating currents and face each other. Due to the structure of the reaction kettle for producing medical intermediates, production efficiency can be effectively improved, and the production cost can be effectively reduced.

Description

technical field [0001] The invention relates to a reaction kettle for producing pharmaceutical intermediates, which is used in the field of preparation of pharmaceutical intermediates. Background technique [0002] Most of the feeding methods of the existing reactors are direct feeding through the feeding pipe. Using the above-mentioned feeding method in the reactor will lead to the dispersion of the material, resulting in incomplete reaction, resulting in the loss of raw materials, and then increasing the cost. [0003] The stirring method of the reactor is generally stirred by the stirring rod, and the stirring efficiency is not high. At the same time, the stirring rod is prone to failure, requires frequent maintenance, and the maintenance operation is difficult to achieve high-efficiency production. [0004] Therefore be necessary to design a kind of reactor of producing pharmaceutical intermediate, to overcome the above problems. Contents of the invention [0005] The...

Problems solved by technology

[0002] Most of the feeding methods of the existing reactors are direct feeding from the feeding pipe. Using the above-mentioned feeding method in the reactor will lead to the dispersion of the material, resulting in incomplete reaction, resulting in the loss of raw materials, and then increasing the cost.

[0003] However, the stirring method of the reactor is generally stirred by the stirring rod, and the stirring efficiency is not high. At the same time, the stirring rod is prone to failure, and frequent maintenance is required. The maintenance operation is difficult and it is difficult to achieve high-efficiency production.
