Stirring device for producing P-toluenesulfonyl urea

Abstract

The invention relates to the technical field of stirring devices, in particular to a stirring device for producing P-toluenesulfonyl urea. The stirring device comprises a box body, wherein a rotary shaft is fixedly connected to the inside of the box body; a casing pipe is coaxially connected to the outside of the rotary shaft; an outer wall of the casing pipe is fixedly connected with spiral stirring blades; an outer wall of the rotary shaft is connected with a plurality of slide blocks along an axial direction in an isometric way; an inner wall of the casing pipe is provided with sliding chutes at corresponding positions; inner walls of the sliding chutes are connected with two baffles symmetrically; two mounting rooms are arranged on the sliding chutes symmetrically; one side, close to each mounting room, of each baffle is symmetrically connected with a plurality of vertical rods; the vertical rods are fixedly connected with connection plates; the connection plates are fixedly connected with springs; one end of the rotary shaft extends to the outside of the box body and is fixedly connected with a motor; the motor is fixedly connected to box body; the other end of the rotary shaft is in threaded connection with a sealing gland; the top of the box body is provided with a charging hole in a communication manner; a lower part of a side wall of the box body is provided with a discharging hole in a communication manner. By adopting the stirring device, detachable spiral blades are provided, raw materials can be stirred well, and production quality after mixing the raw materialis improved.

Description

technical field [0001] The invention relates to the technical field of stirring devices, in particular to a stirring device for producing p-toluenesulfonylurea. Background technique [0002] There are more than 150 million diabetic patients in the world, and it will gradually increase. There are about 50 million diabetic patients in my country, ranking second in the world. At present, oral hypoglycemic drugs commonly used in clinic mainly include α-glucosidase inhibitors, sulfonamides and biguanides, among which sulfonylurea hypoglycemic drugs are the most widely used class. Gliclazide and tolbutamide are mainstream hypoglycemic drugs at home and abroad, and they are used in large quantities. They are produced by major domestic pharmaceutical manufacturers. p-toluenesulfonylurea is used as an intermediate in the production of gliclazide and tolbutamide. The consumption is gradually increasing, the product is in short supply, and the market prospect is very broad. Therefore,...

Problems solved by technology

In the process of synthesizing p-toluenesulfonylurea, the raw materials need to be mixed and stirred. Many stirring devices in the prior art have the disadvantage of uneven stirring. At the same time, the stirring structure is inconvenient to disassemble, which causes great damage to maintenance and replacement. Trouble, which not only reduces production efficiency, but also reduces the quality of production
