Description

Technical Field

[0001] This utility model relates to the field of pressure regulation technology, and in particular to an automatic pressure regulation device for a chemical reactor. Background Technology

[0002] A reactor is a device used to realize a reaction process, widely used in chemical, oil refining, and metallurgical industries. Reactors are used to realize single-phase liquid reactions and multiphase reactions such as liquid-liquid, gas-liquid, liquid-solid, and gas-liquid-solid reactions. They are often equipped with a stirring device. When the material needs to be heated or cooled during the reaction, a jacket can be installed on the reactor wall, or a heat exchange surface can be installed inside the reactor. Heat exchange can also be achieved through external circulation. Chemical reactors require automatic pressure regulating devices to adjust the internal pressure during operation.

[0003] According to the patent application published on the Internet (authorization announcement number: CN222351706U), "This utility model relates to the field of automatic pressure regulating valves and discloses an automatic pressure regulating device for a chemical reactor, including a pressure regulating valve and a cartridge. One end of the cartridge is fixedly equipped with a first limiting plate, and the other end is provided with an insertion groove. The inner wall of the insertion groove is fixedly equipped with multiple baffles. The other end of the cartridge is symmetrically provided with a movable groove, which is located on both sides of the insertion groove. A movable plate is provided in the movable groove. This utility model solves the problem that existing flanges are fixed with bolts and nuts, which are prone to loosening after long-term use, leading to poor airtightness between pipelines and affecting the performance of the chemical pressure regulating valve. This is achieved through the cooperation between the cartridge and the mounting flange and the fixed flange."

[0004] Regarding the above description, the applicant believes the following problems exist: The device is fixed to the assembly flange via bolts, with the bolt caps fitting against the surface of the assembly flange and the nuts fitting against the surface of the fixed flange. Pressing the operating lever stretches the telescopic spring, causing the movable plate to move on the movable slot, inserting the locking blocks on the baffle into the two slots of each group. When the locking blocks fit against the fixed flange and the assembly flange respectively, and the baffle fits against the bolt caps and nuts respectively, with the threaded rod located inside the baffle, releasing the operating lever causes the movable plate to move under the elastic force of the telescopic spring. The locking blocks on the plate engage with the locking slots on the slots. The external threads on the locking box twist with the internal threads on the sleeve, and the sleeve rotates and moves on the locking box until one end of the sleeve is in contact with the second limiting plate. At this time, the operating rod is located inside the shielding cylinder to prevent accidental pressing of the operating rod and improve the operating effect. However, the pressure regulating valve of this device can only perform pressure relief. Complex chemical reactions (such as staged pressure-controlled polymerization reactions and catalytic reactions) require pressure adjustment in stages (such as first increasing the pressure to initiate the reaction, and then decreasing the pressure to promote product separation). The pressure relief device alone cannot meet the requirements of such processes, which limits the application range of the reactor. Utility Model Content

[0021] Please see Figures 1-5 This utility model provides an embodiment: an automatic pressure regulating device for a chemical reactor, including a support frame 1, a one-way valve 602, and a pressure relief component. A hollow reactor 2 is fixedly connected to the outside of the support frame 1. A pressure gauge 3 is installed outside the reactor 2. A first pipe 4 and a second pipe 5 are fixedly connected to the outside of the reactor 2. A pressure relief component is installed outside the first pipe 4. A one-way valve 602 is fixedly connected to the outside of the second pipe 5. A first outer shell 601 is fixedly connected to the outside of the second outer shell 601. A motor 606 is fixedly connected to the outside of the first outer shell 601. An impeller 607 is fixedly connected to the output end of the motor 606. A ventilation duct 608 is fixedly connected to the outside of the first outer shell 601. A second outer shell 603 is installed outside the ventilation duct 608. A filter screen 605 is fixedly connected inside the second outer shell 603. A bolt 604 is threaded inside the second outer shell 603. The impeller 607 is activated by starting the motor 606. 07 rotates, and the impeller 607 draws air into the ventilation duct 608 through the filter screen 605, then into the outer casing 601, and then into the reactor 2 through the one-way valve 602, which helps to increase the pressure in the reactor 2. At the same time, the pressure gauge 3 is observed. When the pressure in the reactor 2 is adjusted to a suitable pressure, the motor 606 is turned off. The filter screen 605 helps to filter the drawn-in air. The outer casing 603 is fixed to the ventilation duct 608 by bolts 604, which makes it convenient for the user to disassemble and replace the filter screen 605. The one-way valve 602 prevents the gas in the reactor 2 from being discharged through the pipe 5.

[0022] Preferably, the ventilation duct 608 has a threaded hole, and the bolt 604 is threaded into the interior of the ventilation duct 608 through the threaded hole, which facilitates the connection of the ventilation duct 608 to the outer casing 603 by the bolt 604.

[0023] Preferably, a through hole is provided on the outer shell 601, and the impeller 607 is rotatably connected to the inside of the outer shell 601 through the through hole, which is conducive to the motor 606 driving the impeller 607 to rotate, thereby facilitating the impeller 607 to pressurize the reactor 2.

[0024] Please see Figures 2-5 In this embodiment, the pressure relief assembly includes a housing 701, which is fixedly connected to the outside of pipe 4. An air outlet pipe 708 is fixedly connected to the outside of housing 701, and a solenoid valve 709 is fixedly connected to the outside of air outlet pipe 708. A filter screen 710 is fixedly connected inside air outlet pipe 708. An air outlet pipe 707 is fixedly connected to the outside of housing 701, and a fixing mesh 711 is fixedly connected inside air outlet pipe 707. A fixing block 706 is fixedly connected inside housing 701, and a sealing block 705 is provided on the outside of the fixing block 706. A spring 704 is fixedly connected to the top of the sealing block 705, and a telescopic tube 713 is fixedly connected to the top of the sealing block 705. A sliding rod 703 is fixedly connected to the outside of the spring 704, and a telescopic tube 712 is fixedly connected to the bottom of the sliding rod 703. The sliding rod 703 is externally threaded. With a rotating handle 702, this component has two usage modes. The first mode is to open the solenoid valve 709 to allow air in the reactor 2 to be discharged through the second air outlet pipe 708, which is beneficial for the user to actively release pressure. The second mode is that when the pressure inside the device exceeds the elastic force of the spring 704, the air pressure pushes the sealing block 705 upward until the sealing block 705 moves to the position of the second fixed mesh 711, at which point the air is discharged from the first air outlet pipe 707, thus allowing the device to automatically release pressure. At the same time, rotating the rotating handle 702 can move the sliding rod 703, which can change the elastic force of the spring 704, thereby increasing or decreasing the pressure for automatic pressure release of the device. The closer the sliding rod 703 is to the fixed block 706, the greater the required pressure, and the farther away it is, the smaller the pressure. Meanwhile, the presence of the second fixed mesh 711 and the second filter mesh 710 prevents external dust from falling into the outer casing 701.

[0025] Preferably, the outer casing 701 has a through hole 2, and the rotating handle 702 is rotatably connected to the inside of the outer casing 701 through the through hole 2, which facilitates the lifting and lowering movement of the sliding rod 703 by rotating the rotating handle 702.

[0026] Preferably, the outer shell 701 has a through hole 3, and the sealing block 705 is slidably connected to the inside of the outer shell 701 through the through hole 3, which is conducive to the air pressure in the reactor 2 pushing the sealing block 705, thereby facilitating the depressurization of the reactor 2.

[0027] Preferably, the telescopic tube 712 has a through hole 4, and the telescopic tube 713 is slidably connected to the inside of the telescopic tube 712 through the through hole 4, which is conducive to the movement of the telescopic tube 713 and the limiting sealing block 705 of the telescopic tube 712, thereby preventing the sealing block 705 from moving or shifting.

[0028] During operation, the impeller 607 is rotated by starting the motor 606. The impeller 607 draws air into the ventilation duct 608 through the filter screen 605, then into the outer casing 601, and finally into the reactor 2 through the one-way valve 602, thus increasing the pressure in the reactor 2. The pressure gauge 3 is monitored. When the pressure in the reactor 2 is adjusted to a suitable level, the motor 606 is turned off. The filter screen 605 effectively filters the drawn-in air. The outer casing 603 is fixed to the ventilation duct 608 by bolts 604, allowing for easy removal and replacement of the filter screen 605. The one-way valve 602 prevents gas from entering the outer casing 601 through the pipe 5. There are two methods for depressurization: the first... By opening the solenoid valve 709, the air inside the reactor 2 is discharged through the second air outlet pipe 708, which facilitates the user's active pressure relief. Secondly, when the pressure inside the device exceeds the elastic force of the spring 704, the air pressure pushes the sealing block 705 upward until the sealing block 705 moves to the position of the second fixed mesh 711, at which point the air is discharged from the first air outlet pipe 707, thus allowing the device to automatically release pressure. At the same time, by rotating the rotating handle 702, the sliding rod 703 can be moved, thereby changing the elastic force of the spring 704, which helps to increase or decrease the pressure for automatic pressure relief. The closer the sliding rod 703 is to the fixed block 706, the greater the required pressure, and the farther away it is, the smaller the pressure. Meanwhile, the presence of the second fixed mesh 711 and the second filter mesh 710 prevents external dust from falling into the outer casing 701.

[0029] Through the above steps, the impeller 607 is rotated by starting the motor 606. The impeller 607 draws air into the ventilation duct 608 through the filter screen 605, then into the outer casing 601, and then into the reactor 2 through the one-way valve 602. This helps to increase the pressure in the reactor 2. At the same time, the pressure gauge 3 is observed. When the pressure in the reactor 2 is adjusted to a suitable pressure, the motor 606 is turned off. The filter screen 605 helps to filter the drawn-in air. The outer casing 603 is fixed to the ventilation duct 608 by bolts 604, which makes it convenient for the user to disassemble and replace the filter screen 605. The one-way valve 602 prevents the gas in the reactor 2 from entering the outer casing 601 through the pipe 5. Through the above settings, the process adaptability of the reactor 2 is increased.
