Multi functional reaction kettle resin production equipment has a long service life

Description :

　　The materials of reaction vessels generally include carbon manganese steel, stainless steel, zirconium, nickel based (Hastelloy, Monel) alloys, and other composite materials. The reaction vessel can be made of stainless steel materials such as SUS304 and SUS316L. Blenders come in anchor, frame, paddle, turbine, scraper, and combination types. The rotating mechanism can use cycloidal pinwheel reducers, continuously variable speed reducers, or variable frequency speed reducers to meet the special reaction requirements of various materials. The sealing device can adopt sealing structures such as mechanical seals and packing seals. Heating and cooling can be achieved through structures such as jackets, half tubes, coils, and Miller plates. Heating methods include steam, electric heating, and thermal oil to meet the process requirements of different working environments such as acid resistance, high temperature resistance, wear resistance, and corrosion resistance. And it can be designed and manufactured according to the user's process requirements.

　　When using a stainless steel reactor, the refrigerant inlet valve must be closed, the remaining refrigerant in the pot and jacket must be drained, and then the material must be input. The mixer should be started, and then the steam valve and electric power supply should be turned on. After reaching the desired temperature, the steam valve and electric power supply should be turned off first. After 2-3 minutes, the mixer should be turned off. After processing is completed, the remaining condensed water in the pot and jacket should be drained, and the sticky material should be washed away as soon as possible with warm water. Then, the inner wall of the container should be thoroughly cleaned with 40 ℃ -50 ℃ alkaline water, and rinsed with clean water. Especially when there is no material (heat absorbing medium) in the stainless steel reactor pot, the steam valve and electric power supply should not be turned on. Pay special attention to the use of steam pressure. Do not exceed the rated work pressure.

　　Maintenance of reaction kettle

　　(1) Installation location: The reaction vessel should be installed in a high-pressure operating room that meets explosion-proof requirements. When multiple reaction vessels are equipped, they should be placed separately, and a safe explosion-proof wall should be used to separate each two vessels. Each operating room should have a passage and outlet to the outside, and good ventilation should be ensured when explosive media is present.

　　(2) After opening the packaging, check for any damage to the equipment. Install the equipment according to the structural diagram based on the equipment model, and verify the components provided according to the packing list. If the heating method is thermal oil electric heating, please purchase the corresponding model of thermal oil according to the operating temperature (note: thermal oil does not allow moisture) and add it. When adding, open the oil filling port on the upper part of the jacket and the oil level port on the upper part of the jacket. Add oil through the filling port until the oil level flows out; Twist the oil level port tightly afterwards, do not twist the oil filling port tightly to avoid pressure.

　　(3) Installation and sealing of kettle body and kettle cover: The kettle body and kettle cover are in line contact with the circular arc surface using gaskets or conical surfaces, and are tightly pressed against each other by tightening the main nut to achieve a good sealing effect. When tightening the nut, it must be diagonally symmetrical and gradually tightened multiple times with even force. It is not allowed for the kettle cover to tilt to one side to achieve a good sealing effect. When tightening the main nut, do not exceed the specified tightening torque range of 40-120N. M to prevent the sealing surface from being crushed or overloaded for wear. Special care should be taken for the sealing surface. Before each installation, use a soft paper or cloth to wipe the upper and lower sealing surfaces clean, and be careful not to touch the sealing surfaces of the kettle body and lid. If operated reasonably, it can be used more than tens of thousands of times. After the sealing surface is damaged, it needs to be reprocessed and repaired to achieve good sealing performance. When disassembling the kettle cover, it should be slowly lifted up and down to prevent the sealing surfaces between the kettle body and the kettle cover from colliding with each other. If gaskets (PTFE, aluminum, copper, asbestos, etc.) are used for sealing, a good sealing effect can be achieved by tightening the main nut.

　　(4) The installation of valves, pressure gauges, and safety valves achieves a sealing effect by tightening the positive and negative nuts. The circular sealing surfaces at both ends of the connection must not rotate relative to each other. When assembling all screw connections, lubricant or graphite mixed with oil must be applied to prevent them from biting. The use of valves: Needle valves are line sealed, and good sealing performance can be achieved by gently rotating the valve needle and compressing the sealing surface. Excessive force is prohibited to avoid damaging the sealing surface.

　　(5) After the equipment is installed, introduce a certain amount of nitrogen and maintain pressure for 30 minutes to check for any leaks. If any leaks are found, use soap foam to locate the leakage points in the pipelines and pipe openings. After finding them, release the gas and tighten them. Then, conduct a nitrogen pressure test again to ensure that there are no leaks before starting normal operation.

　　Stainless steel reaction vessels have the characteristics of rapid heating, high temperature resistance, corrosion resistance, hygiene, no environmental pollution, no need for boiler automatic heating, and easy use. They are widely used in petroleum, chemical, rubber, pesticide, dye, medicine, food, and are used to complete processes such as vulcanization, nitration, hydrogenation, alkylation, polymerization, and condensation. The premise is to fully mix the reactants. For physical changes such as heating, cooling, liquid extraction, and gas absorption, stirring devices are required to achieve good results. We can also design and process external coil reaction vessels for customers.

　　The atmospheric pressure stainless steel electric heating reaction kettle has the characteristics of rapid heating, high temperature resistance, corrosion resistance, hygiene, no environmental pollution, electric heating stainless steel reaction kettle, no need for boiler automatic heating, convenient use, and low price. Widely used in industries such as chemical, pharmaceutical, and food, the material is made of 304 stainless steel.
