Overview
GR-30EX explosion-proof three-layer Glass Reaction Kettle is a equipment produced by GREATWALL for material synthesis, distillation, condensing and other experiments. The kettle body adopts a three-layer Glass structure, the inner jacket can be passed into the circulating liquid to adjust the material temperature, and the outer jacket can be vacuumed to achieve heat preservation, and can work under normal or negative pressure conditions.
Features
1. Made of high borosilicate Glass, it has excellent physical and chemical performance.
2. Operating temperature range is wide, can be used in -80 ℃ to 200 ℃.
3. Can work under normal pressure and negative pressure conditions, Vacuum Level can reach 0.095 MPa, and the pressure range in the kettle is -0.1 MPa to 0 MPa.
4. The key sealing parts are made of Teflon + FV rubber material or additional TFE protective layer, which is resistant to corrosion.
5. Equipped with casters, easy to move; compact structure, saving space.
6. The discharge valve is a liquid-free side discharge valve with a reasonable height design for easy discharge.
7. Adopt variable frequency speed motor, Stirring Speed range is 50~ 500rpm.
8. With Exd ⅱ BT4 Explosion-proof level, high security.
Principle
The Reaction Kettle adjusts the reaction temperature of the material in the kettle by introducing a circulating liquid at a certain temperature into the inner jacket of the three-layer kettle body. At the same time, the outer jacket can be pumped to a vacuum state by a vacuum pump to form an insulation layer to reduce heat loss. By adjusting the valve on the constant pressure funnel, the uniform dripping of materials can be controlled, and the condenser is used for heat exchange to realize the distillation recovery of the product. The stirring system drives the Impeller through the motor to mix the materials evenly.
Applications
Material synthesis, distillation, condensing, etc
Standards
Explosion-proof level: Exd ⅱ BT4
Steps
1. Check whether the components of the equipment are well connected.
2. According to the experimental requirements, the circulating liquid is injected into the jacket through the inlet and outlet of the jacket to set the temperature.
3. If heat preservation is required, connect the outer jacket to the vacuum pump and pump it to a vacuum state.
4. Add the reaction material through the solid feeding port or the liquid feeding port.
5. Start the variable frequency speed motor and set the required stirring Rotation speed.
6. Through the constant pressure funnel and control valve to control the uniform drop of materials.
7. During the reaction, condenser can be used for distillation recovery.
8. After the reaction is completed, the material is discharged through the side discharge valve.
Notice
• Please ensure that the Operating Pressure is within the tolerance range marked on the kettle body (-0.1MPa~ 0MPa).
• During operation, it should be noted that the temperature difference between the inside and outside of the jacket should not exceed 90 ° C.
• Operating temperature must not exceed the marked Operating temperature range (-80~ 200 ℃).
• Ensure that the power supply specification is 220-240V~, 50/60HZ.
• Pay attention to stability when moving the device to avoid colliding with Glass parts.
• Be careful when feeding, discharging and adjusting valves.
• Maintain the cleanliness and sealing of each grinding port and flange connection.
