Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery diaphragm material processing, in particular to a high-temperature and high-pressure reaction kettle for lithium battery diaphragm material processing. Background Art

[0002] The four key materials of lithium-ion batteries are positive electrode materials, negative electrode materials, electrolytes and diaphragms. The diaphragm is one of the key inner components. The performance of the diaphragm material determines the interface structure and internal resistance of the lithium-ion battery, which directly affects the battery's capacity, cycle and safety performance. Diaphragm materials with excellent performance are important for improving the comprehensive performance of the battery. The broad understanding of the reactor is a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process can be achieved.

[0003] However, when the existing high-temperature and high-pressure reactor is used, the lithium battery diaphragm material is usually placed in the reactor for high-temperature and high-pressure processing. However, the heat generated in the reactor will dissipate outward through the surface of the reactor, resulting in a waste of resources. At the same time, when the lithium battery diaphragm material is processed inside the reactor, a certain noise will be generated. The noise sound waves will propagate outward through the reactor, causing harm to the workers. After the lithium battery diaphragm material is processed in the reactor, the temperature in the reactor is still relatively high. When the workers directly open the reactor, they will be scalded by the heat in the reactor. Therefore, a high-temperature and high-pressure reactor for processing lithium battery diaphragm materials is provided. Utility Model Content

[0004] The main purpose of the utility model is to provide a high-temperature and high-pressure reactor for processing lithium battery diaphragm materials. The utility model solves the problem that the existing high-temperature and high-pressure reactor for processing lithium battery diaphragm materials cannot improve the sealing performance of the reactor body, the thermal insulation and noise reduction performance of the reactor body, and it is inconvenient to quickly cool down the reactor body during use through the arrangement of the shell, cylinder, fixed cover, thermal insulation layer A, thermal insulation layer B, sound insulation layer A, sound insulation layer B, cavity, fixed tube A and fixed tube B.

[0005] The technical solution adopted by the utility model to solve its technical problems is a high-temperature and high-pressure reactor for processing lithium battery diaphragm materials, comprising a reactor body, the outside of the reactor body is bolted to a motor for driving a stirring rod to stir the lithium battery diaphragm material, the outside of the reactor body is bolted to a shell for protecting the reactor body, a sound insulation layer A for soundproofing the reactor body is screwed to the inside of the shell, a heat insulation layer A for heat preservation of the reactor body is screwed to one side of the sound insulation layer A, a cavity for quickly cooling the reactor body is screwed to the inside of the heat insulation layer A, and a screw is screwed to the bottom of the reactor body. A base supporting the reactor body is bolted, a cylinder driving the driving plate to move is bolted on the outside of the base, a driving rod connected to a fixed cover is welded on the outside of the driving plate, a sound insulation layer B for reducing noise of the reactor body is screwed inside the fixed cover, a thermal insulation layer B for reducing heat loss in the reactor body is screwed on one side of the sound insulation layer B, a rubber pad for improving the sealing of the fixed cover and the shell is screwed on one side of the shell, a fixed tube A for injecting liquid into the internal cavity of the shell is inserted at the top of the outer side of the shell, and a fixed tube B for discharging the liquid in the cavity is inserted at the bottom of the outer side of the shell.

[0006] By adopting the above technical solution, when the lithium battery diaphragm material is placed in the reactor body, the cylinder on the base uses compressed gas as a medium to work, and then converts the pressure energy of the compressed air into mechanical energy. The cylinder drives the driving rod on the driving plate to move, and then the driving rod drives the fixed cover to move to the outside of the reactor body, and then the fixed cover is in close contact with the rubber pad outside the shell, thereby improving the sealing of the reactor body;

[0007] When the lithium battery diaphragm material is placed inside the reactor body for high temperature and high pressure treatment, the insulation layer A in the shell and the insulation layer B in the fixed cover are both made of graphite polystyrene board. The graphite polystyrene board has special graphite particles inside and contains infrared absorbers that can greatly improve the thermal insulation performance, thereby reducing the heat loss in the reactor body. At the same time, the sound insulation layer A outside the insulation layer A and the sound insulation layer B outside the insulation layer B are both made of ceramic fiberboard. When the noise sound waves in the reactor body propagate to the ceramic fiberboard, multiple refractions and reflections will occur, thereby achieving effective absorption and isolation of the noise. At the same time, the ceramic fiberboard has excellent high temperature resistance, thereby improving the thermal insulation and noise reduction performance of the reactor body.

[0008] After the reactor body processes the lithium battery diaphragm material, water is added to the cavity inside the shell through the fixed tube A outside the shell, and then the water absorbs the heat in the reactor body. The water that absorbs the heat is then discharged outward through the fixed tube B, so that the heat in the reactor body is quickly absorbed, thereby improving the cooling efficiency of the reactor body.

[0009] Specifically, a scraper for scraping the inner wall of the reactor body is welded to the outside of the stirring rod.

[0010] By adopting the above technical solution, when the stirring rod enters the high temperature and high pressure treated lithium battery diaphragm material inside the reactor body to stir, the scraper outside the stirring rod scrapes the inner wall of the reactor body, thereby facilitating the cleaning of the lithium battery diaphragm material adhered to the inside of the reactor body.

[0011] Specifically, a ring plate is welded on the outer side of the fixed cover, and a groove is opened on the surface of the shell to allow the ring plate to enter the interior of the shell.

[0012] By adopting the above technical solution, when the fixed cover contacts the shell, the ring plate outside the fixed cover enters into the groove opened on the surface of the shell, thereby improving the tightness of the connection between the fixed cover and the shell.

[0013] Specifically, a heating plate for heating the lithium battery diaphragm material is fixed by screws inside the reactor body.

[0014] By adopting the above technical solution, after the lithium battery diaphragm material is placed inside the reactor body, the heating plate inside the reactor body heats the lithium battery diaphragm material.

[0015] Specifically, the input ends of the motor and the reactor body are electrically connected to the output end of the external power supply.

[0016] By adopting the above technical solution and connecting to an external power source, the electrical device can work normally.

The cylinder drives the driving rod on the driving plate to move, and then the driving rod drives the fixed cover to move to the outside of the reactor body. Then the fixed cover is in close contact with the rubber pad outside the shell, thereby improving the sealing of the reactor body;
