In the laboratory, the reaction kettle is a common device for carrying out various chemical reactions. It runs smoothly, is easy to operate, and has no noise. This article introduces some points to be noted when installing the laboratory reaction kettle.
1. Installation location: The laboratory reactor should be installed in a high-pressure operation room that meets the explosion-proof requirements. When multiple reactors are equipped, they should be placed separately, and each two should be separated by a safe explosion-proof wall. Each operation The room must have channels and outlets to the outdoor. When there are explosive media, the equipment should be well ventilated.
2. After opening the package, check whether the device is damaged, install the device according to the model of the device according to the structural drawing, and check the parts according to the packing list to see if there are any missing parts.
3. Clean the inside of the kettle of the laboratory reaction kettle: use the cleaning solution to remove the residues of the kettle body and the sealing surface after each operation. Always clean and keep clean, and do not use hard substances or rough surface objects.
4. Installation and sealing of the body and lid of the laboratory reaction kettle: the body and lid are sealed with stainless steel spiral wound gaskets. Tighten the main nut to make them tight to each other to achieve a good sealing effect. The angle symmetry is tightened gradually and repeatedly with even force, otherwise the kettle lid will tilt to one side, and a good sealing effect will not be achieved.
5. The feed tank and condenser should be used under vacuum conditions. When the pressure is generated during the reaction, the needle valve connected to the feed tank and the condensation system must be closed to prevent the glass level gauge, feed tank and condensation from being too high. The device is damaged to avoid danger.
6. Installation of valves and connecting fittings, safety valves, temperature measuring protection tubes: the sealing effect is achieved by tightening, the arc sealing surfaces of the two ends of the connection must not rotate relative to each other, all lubricants must be applied with lubricant during assembly Or graphite blended with oil, so as not to open again.
7. After the equipment is installed, pass a certain amount of nitrogen to maintain the pressure for 30 minutes to see if there is any leakage. If you find a leak, use soap foam to find the leak point. After finding out, let go of the gas and tighten it. Holding pressure test to ensure normal operation after ensuring no leakage.
8. Before starting the laboratory reaction kettle, cooling water should be passed through the water between the magnetic stirrer and the lid of the kettle to ensure that the water temperature is less than 35 ° C to avoid demagnetization of the magnetic material.
