Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a reaction kettle which is convenient for maintaining pressure. Background Art

[0002] Reactors are widely used in the fields of petroleum, chemical industry, rubber, pesticide, dye, medicine and food. They are pressure vessels used to complete process such as vulcanization, nitration, hydrogenation, hydrocarbonization, polymerization, condensation, etc., such as reactors, reaction pots, decomposition pots, polymerization kettles, etc.; the materials are generally carbon manganese steel, stainless steel, zirconium, nickel-based (Hastelloy, Monel, Inconel) alloy and other composite materials.

[0003] Some substances need to react within a certain pressure range during thermal polymerization to ensure quality stability. The existing method of ensuring the stable pressure value in the reactor is to install a pressure gauge on the reactor and manually detect the change in the pressure value in the reactor during the reaction. As the reaction intensifies during the reaction, the heat generated by the reaction will increase. When the pressure gauge display value exceeds the pressure value required for the reaction, the heat in the reactor is promptly removed by manually starting the pressure reducing valve. The entire process of maintaining the stable pressure in the reactor has a low degree of automation and relies heavily on manual labor, making it difficult to ensure product quality and lacking certain practicality.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1

[0027] See also Figure 1-4 , a reactor for maintaining pressure, comprising a main body component 1; the main body component 1 comprises a support frame 11, the inner side of which is fixedly connected to a reactor body 12; a controller 13, arranged on the reactor body 12; a pressure relief valve 14, arranged on the reactor body 12; an adjustment component 2 is arranged on the support frame 11, and the adjustment component 2 comprises: a mounting plate 21, fixedly connected to the top of the support frame 11; a pressure regulating pipe 22, which passes through the mounting plate 21 and is inserted into the reactor body 12, and the pressure relief valve 14 is fixedly connected to the outer wall of the pressure regulating pipe 22; a pipe body 23, which is inserted into the pressure regulating pipe 22 and is fixedly connected to the pressure regulating pipe 22; a pressure sensor 24, which is fixedly connected to the regulating The inner wall of the pressure tube 22; the piston 25, which is slidably connected to the inside of the tube body 23; the one-way valve 26, which is fixedly connected to the inside of the pressure regulating tube 22, and two of them are symmetrically arranged; the driving mechanism 27, which is arranged on the support frame 11; the driving mechanism 27 includes: a servo motor 271, which is fixedly connected to the top of the mounting plate 21; a turntable 272, which is fixedly connected to the output end of the servo motor 271; a fixed column 273, which is fixedly connected to the outer wall of the turntable 272; a driving rod 275, which is fixedly connected to the top of the piston 25; a connecting plate 274, which is hinged to the outer wall of the fixing column 273, and the driving rod 275 is hinged to the outer wall of the connecting plate 274; a filter 4 is fixedly connected to the inside of the pressure regulating tube 22.

[0028] When ready for use, the reactor body 12 is installed at the designated position through the support frame 11, and the inert gas delivery pipeline is connected to the pressure regulating pipe 22 on the mounting plate 21, and then the material is placed in the reactor body 12 for use. When the internal pressure of the reactor body 12 is relatively high, the pressure relief valve 14 setting value is reached at this time, and the pressure relief valve 14 automatically opens to release the excess pressure. When the internal pressure of the reactor body 12 is relatively low, the pressure sensor 24 transmits a switch signal to the controller 13, and the controller 13 automatically opens the drive mechanism 27 and the electromagnetic valve inside the pressure regulating pipe 22. The drive mechanism 27 drives the piston 25 to move up and down. Since the two one-way valves 26 only allow the gas to move toward the reactor body 12, the inert gas is drawn into between the two one-way valves 26 when the piston 25 moves upward, and the piston 25 pushes the inert gas into the reactor body 12 for pressurization when the piston 25 moves downward. When the appropriate pressure is reached, After that, the battery valve and the driving mechanism 27 in the pressure regulating tube 22 are automatically closed, which can ensure the internal pressure of the reactor body 12. At the same time, the whole process does not require manual operation by the operator, which improves the practicality of the device; the pressure sensor 24 transmits the switch signal to the controller 13, and the controller 13 automatically turns on the servo motor 271. The output end of the servo motor 271 drives the turntable 272 to rotate, and the rotation of the turntable 272 drives the fixed column 273 to rotate at the same time. The rotation of the fixed column 273 drives the driving rod 275 to move up and down through the connecting plate 274, so that the driving rod 275 drives the piston 25 to move up and down to pressurize the device, without manual operation, which improves the convenience of the device; the pressure regulating tube 22 is fixedly connected with a filter 4, and the filter 4 can prevent impurities in the inert gas, or dust remaining on the inner side of the pressure regulating tube 22 that is not used for a long time from entering the reactor body 12, affecting the normal progress of the reaction, thereby improving the stability of the device.

[0029] Embodiment 2

[0032] During use, when the driving mechanism 27 drives the piston 25 to complete the pressurization, the operator can twist the threaded rod 32 by hand to make the push block 33 slide toward the pressure regulating tube 22 inside the fixed tube 31, thereby changing the area occupied by the gas and further pressurizing to prevent the piston 25 from being too precise when pressurizing. The operator can fine-tune the pressure through the fine-tuning component 3, thereby improving the practicality of the device; the bottom end of the threaded rod 32 is fixedly connected to a rotating wheel 5, and the operator can drive the threaded rod 32 to rotate by turning the rotating wheel 5, preventing the operator from directly rotating the threaded rod 32 which is inconvenient, and facilitating the operator to exert force with the palm of his hand, thereby improving the convenience of the device; scale lines are set on the mounting plate 21, so that the operator can observe the bottom of the threaded rod 32 according to the scale lines, thereby facilitating accurate control of the degree of fine-tuning, thereby improving the stability of the device.
