　　1、 Product Introduction

Explosion proof rotary evaporator is a commonly used high-efficiency separation equipment in laboratories, widely used in fields such as chemistry, pharmaceuticals, food, and environmental protection, especially in experiments that require low-temperature and high-efficiency evaporation conditions for purifying and separating liquids. As a special version of the rotary evaporator, it adopts advanced explosion-proof design to cope with the risk of using flammable and explosive solvents in the experimental environment, effectively improving the safety of the experiment.

With the gradual improvement of laboratory safety standards, the market demand for explosion-proof rotary evaporators is also increasing. Its explosion-proof function mainly provides reliable protection against dangerous situations such as gas leakage and solvent vapor accumulation that may occur during the experimental process.

　　2、 Working principle

The basic working principle is to use a rotating container to heat and evaporate the sample, and to cool and recover the evaporated solvent gas through a condensation system. Its operation is usually divided into the following steps:

1. Heating: The solvent in the sample bottle is heated by water bath or oil bath, and the solvent begins to evaporate under the heating effect. Due to the fact that the heating temperature is usually controlled within a lower range, excessive solvent evaporation is avoided, reducing the decomposition of heat sensitive substances.

2. Rotation: The sample bottle is driven to rotate by a motor, which can evenly heat the liquid inside the bottle and increase the surface area of the liquid through rotation, thereby accelerating the evaporation process.

3. Condensation: The evaporated solvent gas is cooled through a condenser, where it is condensed into a liquid state by circulating cooling water or other cooling medium, and then returned to the sample bottle or collection bottle through a reflux pipeline.

4. Separation and recovery: After solvent evaporation, it will be separated according to the difference in boiling point of the solvent. Different solvents will evaporate at different temperatures to further purify or separate the solution.

On the basic working principle mentioned above, the explosion-proof rotary evaporator adopts a special explosion-proof design to ensure that even if there are hazardous factors such as solvent vapor leakage during the experimental process, timely warning and corresponding protective measures can be taken to avoid potential explosion hazards.

　　3、 Main structure

The design structure of the explosion-proof rotary evaporator should not only meet the basic functional requirements of the rotary evaporator, but also combine explosion-proof technology to ensure the safe operation of the equipment in flammable and explosive environments. Its main structural components include:

1. Explosion proof motor

Explosion proof motor is one of the core components. The explosion-proof motor adopts a special explosion-proof shell, which can operate safely in flammable and explosive gas environments, preventing electric sparks or high temperatures inside the motor from generating fire sources and causing explosions. Explosion proof motors also have good heat dissipation function, which can effectively prevent motor overheating, improve equipment stability and durability.

2. Rotating system

The rotating system is an important part of the rotary evaporator, responsible for rotating the sample bottle at a certain speed. Explosion proof rotary evaporators are usually equipped with high-speed electric motors to drive the rotating platform, allowing the sample bottle to rotate continuously and uniformly, increasing the evaporation area of the solution and accelerating the solvent evaporation process. The explosion-proof design of the rotating system ensures that even when operating in hazardous environments, the motor and other electrical components will not pose a danger.

3. Heating bath

The heating bath is a component used to heat the solution in the sample bottle. Heating baths are usually heated using water or oil baths, and the temperature can be precisely controlled. Due to the need for evaporation of flammable and explosive solvents, heating baths are often equipped with automatic power-off protection when the temperature is too high, to avoid the risk of excessive solvent evaporation or explosion caused by high temperatures.

4. Condensation system

The condensation system is an important component that rapidly cools and condenses the evaporated solvent gas into a liquid state through a cooler (such as a condenser tube), ensuring solvent reflux and preventing solvent gas leakage to the outside. The design of condensation systems usually adopts water cooling or circulating cooling systems to maintain the high efficiency of condensation effect. Explosion proof design requires strong sealing at the junction of the condenser and pipeline to avoid solvent leakage.

5. Collecting bottles and reflux system

The collection bottle is used to collect the solvent evaporated from the sample bottle. Collection bottles are usually made of high-strength materials that can withstand pressure changes and temperature differences. The reflux system ensures that the solvent can enter the collection bottle through the reflux pipeline and avoids solvent leakage during the experimental process.

6. Explosion proof control system

The explosion-proof control system is an important component responsible for real-time monitoring of the operation of the entire equipment and issuing warnings for potential hazards through an alarm system. The explosion-proof control system can detect abnormal parameters such as current, voltage, temperature, etc., automatically cut off the power or give an alarm, ensuring the safety of the equipment during operation.

7. Explosion proof enclosure and sealing system

The shell and sealing system adopt special explosion-proof design to ensure the safe operation of the equipment in flammable and explosive environments. The material of the equipment casing is generally chosen to be corrosion-resistant and high-temperature resistant metal materials, while the sealing system ensures that solvent gases do not leak to the outside. The shell usually has waterproof and dustproof functions, suitable for various laboratory working environments.

　　4、 Technical features

1. High efficiency evaporation

The explosion-proof rotary evaporator can evaporate at lower temperatures to prevent the decomposition of heat sensitive substances, while accelerating the evaporation process of liquids through rotation, greatly improving the recovery rate and separation efficiency of solvents. Especially suitable for the purification and separation of fine chemicals, drugs, food additives, etc.

2. 高安全性

The advantage lies in its explosion-proof design, which is particularly suitable for experiments dealing with flammable and explosive solvents. Explosion proof motors, sealing systems, heating systems, and condensing systems are all designed with explosion-proof features, effectively reducing the risk of fire or explosion caused by solvent evaporation during the experimental process.

3. Precise control

The equipment is equipped with precise temperature control and speed adjustment systems, which can accurately adjust the heating temperature, rotation speed, and evaporation pressure according to the needs of different samples. The temperature control system can ensure temperature stability during the experimental process and avoid temperature fluctuations affecting the experimental results.

4. Automation and Intelligence

Has a high degree of automation. The equipment can automatically complete heating, rotation, condensation, reflux and other operations during the evaporation process, and can monitor the solvent evaporation rate and solution concentration changes in real time to ensure the accuracy of experimental results. Some models are also equipped with intelligent functions such as data storage, remote control, and automatic alarm, further enhancing the convenience and security of device operation.

5. Easy to clean and maintain

The design of the explosion-proof rotary evaporator takes into account the convenience of laboratory personnel, and all components are easy to disassemble and clean. Sample bottles, condenser tubes, collection bottles and other components can be easily cleaned to avoid cross contamination of samples and ensure the accuracy and safety of each experiment.
