The lifting jacketed double-layer glass reactor

1、 Working principle

The jacketed double-layer glass reactor kettle has a stirring system, condensation, dropwise addition, reflux, and collection system. The reaction solvent is placed in the inner layer for stirring reaction, and the interlayer is circulated by cold and heat sources, which can provide high-temperature reaction (the highest temperature can reach 300 ℃) or low-temperature reaction (the lowest temperature can reach -80 ℃). The lifting jacketed double-layer reactor has upgraded the standard reaction kettle with the function of lifting and rotating the kettle body up and down, which facilitates the cleaning of the kettle body. When the material undergoes a heating reaction, the evaporation efficiency can be improved under vacuum conditions (by connecting a vacuum device). The solvent vapor is cooled into a liquid through a glass condenser coil (by connecting a cooling device), which can be refluxed into the kettle or recovered through the lower valve of the reflux elbow. After the reaction is complete, the material can be discharged from the side outlet at the bottom of the kettle. Moreover, the fully transparent reaction process is clear at a glance, making it an ideal experimental pilot equipment for modern biopharmaceuticals, fine chemicals, and new material synthesis.

2、 Product Features

1. This product is a unique device with a square steel spray coating and a 304 stainless steel frame structure. It is compact, sturdy, non slip, corrosion-resistant, and easy to move.

2. All parts in contact with the material are made of high borosilicate glass (expansion coefficient 3.3) and polytetrafluoroethylene material, which have stable performance and are not prone to chemical reactions with the material, making them easy and safe to use.

3. Unique frequency conversion speed regulation allows you to operate at high and low speeds with ideal accuracy and ease. It can be equipped with a fully explosion-proof system, a dual display explosion-proof box with digital display of speed and material temperature inside the kettle, stable performance, clear display of control and data plane, and simple and easy operation.

4. The mixing system adopts ceramic bearings and mechanical seals to prevent wear and debris of the mixing rod, with high temperature resistance, wear resistance, and good sealing effect.

5. Adopt PT100 temperature sensor and glass thermometer sleeve.

6. The kettle body can be raised and lowered up and down, either electrically or manually with a handwheel. The kettle body can rotate 360 degrees for easy discharge and cleaning, and the kettle cover can be customized with PTFE.

7. The vacuum pressure gauge displays real-time vacuum and the pointer displays.

8. Crescent shaped stirring blade, made of 304 stainless steel and PTFE stirring blades; The material of the stirring rod is 304 stainless steel. Outsourced polytetrafluoroethylene tube, high strength and strong corrosion resistance.

9. Glass+PTFE discharge valve, no liquid accumulation side discharge, very fast solution recovery.

10. The bottom of the machine is equipped with a Fuma wheel with brakes, which can move as a whole and is easy to operate.

11. The circulating inlet and outlet of the kettle body are equipped with buffering devices, and the interior of the pipeline is made of stainless steel hoses, wrapped with foam silicone for insulation. After fixing the pipe bracket, it is connected to external equipment to reduce the pressure at the inlet and outlet, and to avoid the fragility of the kettle body when moving or replacing connecting equipment in the later stage.

12. Explosion proof speed control box, explosion-proof mixing motor, explosion-proof grade EXdIIBT4.
