Description
Technical Field
[0001] The utility model relates to an improved structure of a reaction kettle. Background Art
[0002] Reactors are important equipment in chemical production and are widely used in industries such as petroleum, chemicals, rubber, pesticides, dyes, medicines and food to complete reactions such as sulfidation, nitration, hydrogenation, hydrocarbonization, polymerization and condensation. During the use of the reactor, it is usually necessary to evenly stir the reactants inside and precisely control the temperature to ensure the smooth progress of the reaction and the stability of the product quality.
[0003] Traditional reactors usually include basic structures such as a reactor body, a stirring device, and a temperature control device. However, existing reactors have some shortcomings in actual use. For example, the stirring device usually adopts a simple paddle or anchor stirrer, and its stirring effect is not ideal in high viscosity or solid-liquid mixed systems, which easily leads to uneven distribution of reactants. In addition, traditional temperature control devices generally exchange heat through heating or cooling media outside the reactor body, and the temperature control accuracy and response speed are low, which is difficult to meet high-precision process requirements.

[0014] The valve, the refrigeration module and the heating module are electrically connected to the controller respectively, and the controller controls the operation of the valve, the refrigeration module and the heating module.
[0015] Efficient stirring performance:
[0016] This reactor uses an anchor agitator, which drives the agitator shaft to rotate through a transmission device, achieving efficient stirring of the reactants in the reactor.

[0023] The purpose of the utility model can also be solved by the following technical measures:
[0024] Furthermore, the inner wall of the main body is a stainless steel inner wall, and the inner wall of the main body is pickled and passivated to form a dense chromium oxide film.
[0025] The inner wall of the stainless steel is pickled and passivated to form a dense chromium oxide film, which can effectively block the erosion of external media and significantly enhance the corrosion resistance of the inner wall. It is particularly suitable for handling corrosive reactants or media.
[0026] The chromium oxide film provides a long-term protection mechanism, reducing equipment maintenance and replacement costs due to corrosion and increasing the overall service life of the equipment.
[0027] The surface of the stainless steel inner wall after pickling and passivation treatment is smooth and flat, which reduces the adhesion and residue of reactants on the inner wall, reduces the risk of cross contamination, and helps maintain the purity and quality of the product.
[0028] The treated inner wall is easier to clean and disinfect, avoiding the accumulation of pollutants. It is suitable for industries with high requirements on hygiene conditions, such as pharmaceuticals and food processing.
[0029] After pickling and passivation treatment, the surface roughness of the stainless steel inner wall is reduced, and the heat transfer medium forms a uniform film on the inner wall surface, which improves the heat transfer effect and the heating and cooling efficiency of the reactor.
[0030] The formation of the chromium oxide film improves the chemical stability of the inner wall, and can maintain good heat transfer performance under high temperature and high pressure environments, ensuring the stability of the reaction process.
[0031] The high corrosion resistance of the stainless steel inner wall reduces the risk of perforation or leakage due to corrosion, improves the safety of the equipment, and ensures the safe operation of the production process.
[0032] Pickling passivation treatment can remove stress concentration points on the surface of stainless steel, reducing the risk of stress corrosion cracking, and is particularly suitable for high-pressure reaction environments.
[0033] The treated stainless steel inner wall has excellent corrosion resistance and mechanical properties, which reduces equipment failures caused by corrosion, wear and other factors, and significantly extends the service life of the reactor.
[0034] Due to the improved durability and stability of the equipment, the maintenance frequency and cost are reduced, and the production efficiency and economic benefits are improved.
[0035] By using stainless steel material for the inner wall of the main body of the reactor and performing pickling and passivation treatment, the utility model has achieved significant improvements in corrosion resistance, product purity, heat transfer performance, safety and equipment service life, providing a more efficient and reliable reaction equipment for various chemical, pharmaceutical and food processing industries.
[0036] Furthermore, the outer wall of the main body is made of carbon steel, and the outer wall of the main body is coated with anti-rust primer.
[0037] Applying anti-rust primer on the outer wall of carbon steel can effectively isolate moisture, oxygen and corrosive media in the external environment, prevent carbon steel from rusting and corrosion, and greatly extend the service life of the reactor.
[0038] The protective layer formed by the anti-rust primer has long-term stability and can maintain its protective performance over a long period of time, reducing the frequency and cost of equipment maintenance.
[0039] Carbon steel, as the main outer wall material, has excellent mechanical strength and durability, and can withstand greater pressure and mechanical stress, ensuring the stable operation of the reactor under harsh conditions such as high pressure and high temperature.
[0040] The anti-rust primer has good adhesion to the carbon steel outer wall and is not easy to peel or fall off, further improving the overall durability and reliability of the equipment.
[0041] Through the protection of anti-rust primer, the corrosion loss of the carbon steel outer wall is greatly reduced, which extends the maintenance cycle of the equipment, reduces maintenance costs and downtime, and improves production efficiency.
[0042] The anti-rust primer layer can restore its protective performance through simple repair and re-coating after damage, and the maintenance process is simple and low-cost.
[0043] Anti-rust primer can prevent holes and cracks in the outer wall of carbon steel due to corrosion, reduce the risk of material leakage, and ensure the safety of the production process.
[0044] The application of anti-rust primer can alleviate the stress concentration phenomenon on the outer wall of carbon steel and reduce the risk of stress corrosion cracking, which is particularly suitable for high-pressure reaction environments.
[0045] By using carbon steel material on the outer wall of the main body of the reactor and applying anti-rust primer, the present invention has achieved significant improvements in anti-corrosion performance, durability, maintenance cost, equipment appearance and safety, providing a more efficient, reliable and economical reaction equipment for industries such as chemical, pharmaceutical and food processing.
[0046] Furthermore, the wall thickness of the main body is greater than 12.2 mm.
[0047] The increase in the wall thickness of the main body significantly improves the mechanical strength of the reactor, enabling it to withstand greater internal pressure and external force, reducing the risk of deformation or rupture under high-pressure and high-temperature reaction conditions, and ensuring the long-term stable operation of the equipment.
[0048] Furthermore, the wall thickness of the jacket is greater than 8 mm.
[0049] The increase in jacket wall thickness improves its pressure resistance and structural strength, ensuring that no leakage or damage will occur under the pressure of the heating or cooling medium, ensuring the safety and reliability of the heat exchange process.
[0050] The beneficial effects of the utility model are as follows:
[0051] The utility model, by optimizing the design of the stirring device and the temperature regulating device, not only improves the stirring efficiency and the temperature control accuracy, but also enhances the operating convenience and reliability of the equipment, helps to improve the efficiency of the chemical production process and the product quality, and has significant practical value and economic benefits.
