Core Structure and Principles

1. Magnetic transmission systemStatic sealing is achieved through end face rare earth coupling drivers, avoiding the leakage risk of traditional packing or mechanical seals, especially suitable for reactions in flammable, explosive, and toxic media

2. 釜体材料Common materials include stainless steel (such as 304, 316L), titanium, nickel, etc. Some equipment is lined with polytetrafluoroethylene (PTFE) to enhance corrosion resistance, and the maximum working temperature can reach 250 ℃ (PTFE lining is 180 ℃)

3. Heating and temperature controlAdopting modular heating (such as electric heating and thermal oil heating), the temperature control accuracy can reach ± 1 ℃, supporting real-time temperature monitoring and automatic adjustment

4. mixing systemBuilt in magnetic stirrer with a speed range of 0-1300rpm, suitable for uniform mixing of materials with different viscosities, and the stirring components have good sealing, suitable for long-term use

5. The laboratory magnetic stirring reaction kettle is mainly composed of the kettle body, kettle cover, magnetic stirrer, heater, valve, feeding port, internal cooling coil, safety blasting device, pressure gauge, control instrument, and lifting device
   

It mainly consists of kettle body, kettle cover, connecting flange, magnetic stirrer, heater, valve, cooling coil, safety blasting valve, pressure gauge, control instrument and other components.

　　(1)The kettle body and lid are made of metal materials304Made of lined Hastelloy alloy, the kettle cover is a flat cover, and the kettle body is made of round bar material processed as a whole. The sealing between the kettle body and the kettle cover is sealed with gaskets.

　　(2)Connecting flange: The flange material is35CrMoAThere are bolts evenly distributed in the circumferential direction on the flange, and sealing is achieved by tightening the nuts, ensuring reliable and leak free sealing.

　　(3)Magnetic stirrer: It is driven by a servo motor to rotate the outer magnetic steel body. The outer magnetic steel body drives the inner magnetic steel body, stirring shaft, and stirring blade to rotate through magnetic lines, thereby achieving the purpose of stirring. In order to ensure the normal operation of the magnetic stirrer, a cooling water jacket is installed on the magnetic stirrer. Before each start-up, cooling water must be introduced between the cooling water jackets to reduce the temperature and ensure that the magnetic material of the magnetic stirrer does not demagnetize; Please enter water from the water outlet of the magnetic stirrer and exit water from the water outlet.

　　(4)Heater: The heating of the reaction kettle is achieved through an electric heating tube, which has the characteristics of uniform thermal conductivity, fast heating speed, and long service life. The outgoing line is connected to the control instrument through a junction box and cable; There are slots on both sides of the upper furnace ring of the heating furnace, and hanging columns are installed on both sides of the kettle body. Align the hanging columns with the slots and install them, then rotate them to the right to fix the heating furnace to the kettle body. Otherwise, it can be removed.

　　(5)On the upper and side parts of the kettle cover, there are mixing ports, temperature measuring ports, air inlet ports, exhaust ports, pressure gauge safety blasting valve ports, etc. External valves, pressure gauges, safety blasting valves, temperature measuring protection pipes, etc. are all sealed by contacting with circular arcs and circular arc lines, and achieved by tightening nuts.

Encyclopedia of High Pressure Stainless Steel Distillation ReactorsThe most common malfunction is the magnetic stirrer part. If the stirring shaft has a large swing or produces abnormal noise during use, the shaft sleeve of the magnetic stirrer needs to be replaced. Weihai Zhenhong Chemical Machinery Co., Ltd. reminds that if maintenance is required, please follow the following steps for repair.

1Unscrew the nut on the kettle cover and remove the materials from the kettle. If there is a reaction with flammable, explosive or toxic media, it should be cleaned first.

2Remove the kettle cover component together with the magnetic stirrer, and use a wrench to disassemble the magnetic stirrer.

3Remove the threads connecting the top sealing cap and cooling body to the sealing cover body, and remove the sealing cover body together with the inner and outer magnetic steel rotors and the upper stirring shaft, so that the supporting cooling body can be removed.

Stainless steel distillation reactor materialIt should be placed indoors. When equipping multiple high-pressure reactors, they should be placed separately. Each operating room should have an exit directly leading to the outside or passage, and the equipment grounding point should be ensured to have good ventilation.

Magnetic stirring stainless steel distillation reactorPrinciple safety features

• Pressure and temperature monitoringEquipped with pressure gauges, safety rupture valves, and temperature sensors to ensure experimental safety

• Sealing testBefore use, an inert gas pressure test must be conducted to ensure the sealing performance of the equipment

  Laboratory magnetic stirring reactor system gasLiquid, liquidLiquid, liquidSolid or gasliquidA stirring reaction device for chemical reactions of solid three-phase chemical materials can fully stir various chemical materials under high pressure, vacuum, and temperature to enhance mass and heat transfer processes.
  

When conducting reactions with different media in a reactor, it is necessary to first investigate whether the media corrode the main material. Special orders are required for chemical reactions that cause rapid reactions, generate large amounts of gas, or are flammable and explosive at high temperatures, as well as reactions that cause severe corrosion to stainless steel due to ultra-high pressure, ultra-high temperature, or chloride ions, fluoride ions, etc. in the medium!
When loading the reaction medium, it should not exceed the laboratory reactor body2/3liquid level!
It is strictly prohibited to disassemble under pressure during or after work!It is strictly prohibited for the kettle to work under overpressure or overheating conditions.The main feature of Weihai Zhenhong Chemical Machinery Co., Ltd.'s reaction kettle is the use of a static sealing structure, and the agitator and motor drive are connected by magnetic coupling. Due to its non-contact torque transmission, static sealing is used instead of dynamic sealing to solve the leakage problem of agitation

With its sealing, safety, and flexibility, it has become an ideal choice for high-temperature and high-pressure reactions in scientific research and industry.

1、.The high-pressure reactor needs to bespecificallyUse the location and follow the instructions for use.

2、.Identify the test pressure, operating pressure, and maximum operating temperature conditions engraved on the main container, and use them within their allowable range.
3The pressure used by the pressure gauge is best indicated on the pressure gauge1/2Used internally. And often compare the pressure gauge with the standard pressure gauge and calibrate it.
4、.Oxygen pressure gauges should be avoided from being mixed with pressure gauges used for other gases.
5..Safety valves and other safety devices should use instruments that have undergone regular inspections and meet the specified requirements.
6The.Attention must be paid during operation to accurately insert the thermometer into the reaction solution.

7The interior and lining parts of the high-pressure reactor should be kept clean.
8、.When covering the disc flange cover, the bolts located on the diagonal should be tightened in pairs in sequence.
9When the measuring instrument ruptures, most of the time it breaks on both sides of its glass surface. Therefore, do not stand in these dangerous places during operation. When danger is expected, the glass should be removed and replaced with a new one.

When installing the kettle cover, it is necessary to prevent the sealing surfaces between the kettle body and the kettle cover from colliding with each other. Carefully place the kettle lid in a fixed position on the kettle body, and when tightening the main nut, it must be tightened diagonally and symmetrically in multiple steps. Apply even force and do not allow the kettle lid to tilt to one side to achieve a good sealing effect.

The function and use of laboratory stainless steel distillation reaction kettleThe main material used for the high-pressure reactor body is1cr18Ni10TiMade of stainless steel and capable of producing titanium materials according to different medium requirements(TA2)Nickel(Ni6)And composite steel plates, the kettle structure includes flat lid, convex lid, and closed reaction kettle body with manhole. The opening on the kettle lid can be designed according to user requirements; The heating methods include jacket steam, jacket hot oil electric heating, etc., which can be optionally selected by users when ordering. For the inner surface of the kettle with polishing requirements, it can achieve the above mirror polishing level. For high viscosity materials, it can be processed into a conical bottom for easy feeding and cleaning

When cleaning the high-pressure reactor, special attention should be paid not to let water or other liquids flow into the heating furnace to prevent the heating furnace wire from burning out. If heating the jacket heat transfer oil, be careful not to mix water or other liquids into it when adding heat transfer oil. The oil level of the heat transfer oil should be checked periodically!
If there is abnormal noise inside the isolation sleeve during operation, the machine should be stopped to release pressure and the mixing system should be checked for any abnormal conditions. Regularly check the swing amount of the mixing shaft. If the swing amount is too large, the bearing or sliding shaft sleeve should be replaced in a timely manner!
