Description

Technical Field

[0001] The present application relates to the technical field of reactors, and in particular to a visualized high-temperature and high-pressure reactor. Background Art

[0002] High temperature and high pressure reactor is a container for chemical and chemical reactions. The reactor can realize the heating, evaporation, cooling and low-speed mixing functions required by the process. High temperature and high pressure reactor is widely used in petroleum, chemical, rubber, pesticide, dye, medical, food, and is used to complete the pressure vessel of vulcanization, hydrogenation nitration, polymerization, condensation and other process. The reactor material is generally carbon manganese steel, stainless steel, zirconium, nickel-based (Hastelloy, Monel, Inconel) alloy and other composite materials. When the reactor is in use, the material needs to be added to the reactor through the feed pipe, and the material is subjected to high temperature and high pressure operation through the operation of the corresponding components in the reactor. In order to prevent the internal temperature and pressure of the reactor from being affected during operation, the upper cover needs to be installed on the upper end of the feed pipe and the upper cover needs to be closed.

[0003] The existing Chinese patent with announcement number CN218689254U discloses a high-temperature and high-pressure reactor, including a reactor body, a feed pipe is provided through one side of the upper end of the reactor body, a fixed block is fixed on the upper end of one side of the feed pipe, a pushing mechanism is provided in the fixed block, a moving part is provided on the pushing mechanism, a pressing mechanism is provided in the moving part, and a stirring mechanism is provided in the middle of the upper end of the reactor body. The utility model can replace the traditional multiple bolt structures by the pushing mechanism and the pressing mechanism to install the upper cover on the upper end of the feed pipe, so that the upper cover is more convenient to open and close, thereby improving the convenience of conveying materials into the reactor, effectively improving the convenience of the high-pressure reactor, and can adjust the tightness of the upper cover installed on the upper end of the feed pipe, so that the upper cover is more tightly installed on the upper end of the feed pipe, preventing the temperature and pressure in the high-temperature and high-pressure reactor from leaking, and then can improve the stability of the high-temperature and high-pressure reactor during operation.

[0004] However, the above-mentioned reactor has the following disadvantages: the device can adjust the tightness of the upper cover and the feed pipe by setting the first screw and the nut, so that the upper cover can be installed more tightly, but the pressure inside the reactor is very high, and it is impossible to adjust the first screw and the nut by manual judgment to ensure the tightness of the upper cover and the feed pipe. In addition, when the internal pressure of the reactor increases, the upper cover will be pushed outward. The upper cover and the feed pipe can only be installed by the first screw, and the sealing of the feed pipe cannot be guaranteed.

[0005] Therefore, we propose a visual high-temperature and high-pressure reactor to solve this problem.

[0006] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
