Description

Technical Field

[0001] The utility model relates to the technical field of diaminopyrimidine oxide production, in particular to a diaminopyrimidine oxide production device capable of rapid cooling. Background Art

[0002] Diaminopyrimidine oxide is an important organic compound that is widely used in the fields of medicine, pesticides, dyes, etc. Its production equipment requires multiple steps, among which cooling is a very important step.

[0003] The diaminopyrimidine oxide production device is an industrial equipment for producing diaminopyrimidine oxide. The device mainly includes components such as a feeding system, a reactor, a separation system, a purification system and a product collection system. The feeding system is a device for feeding raw materials into the reactor, mainly including a feeding pump, a flow meter and a feeding pipeline. The raw materials are generally diaminopyrimidine and oxygen, which are fed into the reactor through the feeding system for reaction. The reactor is the core part of the device and is the place where diaminopyrimidine and oxygen react to generate diaminopyrimidine oxide. The reactor usually reacts under high temperature and high pressure to increase the reaction rate and product yield. After the reaction is completed, the reaction mixture needs to be cooled, so a separation system is required. In addition, the purification system is mainly used to remove impurities and impure substances in the diaminopyrimidine oxide. The purified diaminopyrimidine oxide is fed into the product collection system for packaging and storage. The product collection system is mainly used to collect and package the purified diaminopyrimidine oxide, and the purified diaminopyrimidine oxide is packaged into solid or liquid form for easy transportation and sale.

[0004] Among them, the separation system is a device for separating the reaction products, which mainly includes a separation tower, a condenser and a separation pipeline. The separation system separates the reaction products by cooling and reducing pressure. The separated diaminopyrimidine oxide is sent to the purification system for further treatment.

[0005] Existing diaminopyrimidine oxide production devices generally use natural cooling, but the traditional natural cooling method is slow and takes a lot of time, which makes the production cycle long, resulting in low production efficiency and is not suitable for mass production. Therefore, a diaminopyrimidine oxide production device that can cool quickly is needed to solve the above problems. Utility Model Content

Under the characteristics of the inert gas, the diaminopyrimidine oxide in the reaction tank 301 can be quickly cooled down. Then, the fan 3101 is started, and the residual heat of the reaction tank 301 is discharged through the air outlet pipe 309 under the high pressure generated when the fan 3101 is running.

Since the movable limit rod 3052 and the slide rail 3053 are slidably connected, the slide rail 3053 is driven to move under the drive of the movable limit rod 3052, and the push rod 3054 is driven to move up and down, so as to drive the shaking plate 306 to reciprocate, so that the diaminopyrimidine oxide can be driven to shake, and the diaminopyrimidine oxide can be quickly cooled.
