Description

Technical Field

[0001] This utility model relates to the field of pyrolysis reactor technology, and in particular to a pyrolysis reactor that can control the internal pressure of a storage tank. Background Technology

[0002] A pyrolysis reactor is a high-pressure pyrolysis device with catalytic reaction, and it is an analytical instrument used in the field of energy science and technology.

[0003] Current technology cannot effectively control the internal pressure of the storage tank in the pyrolysis reactor. This results in inconsistent internal pressure, affecting the use of the storage tank. Furthermore, the multiple control valves in the pressure control device cannot be effectively protected, allowing unauthorized personnel to easily operate them, which may lead to production problems. Utility Model Content

[0004] To overcome the problems of existing pyrolysis reactor storage tanks being unable to control the internal gas pressure and unable to protect multiple operating valves.

[0005] The technical solution of this utility model is as follows: a pyrolysis reactor capable of controlling the internal pressure of a storage tank, comprising a base, a storage tank body fixedly connected to the top of the base, an mounting base fixedly connected to the outer wall of the storage tank body, a PLC controller mounted on the side of the mounting base, a pressure transmitter disposed below the PLC controller, a breather valve mounted on the top of the storage tank body, a vent hole opened on the top of the storage tank body, a gas pipeline fixedly connected to the top of the storage tank body, a pressure regulating valve mounted on the outer wall of the gas pipeline, a shut-off valve disposed on one side of the pressure regulating valve, a control valve disposed on one side of the shut-off valve, the shut-off valve being disposed between the pressure regulating valve and the control valve, and a sealed container fixedly connected to the end of the gas pipeline away from the storage tank body.

[0006] Preferably, the pressure in the gas pipeline is detected by a pressure transmitter, and the detection result is fed back to the PLC controller. The PLC controller then controls the pressure regulating valve to adjust the pressure inside the storage tank. This achieves the effect of controlling the internal gas pressure of the storage tank. When the gas in the storage tank is insufficient or excessive, the breather valve is opened, allowing it to automatically replenish or release a small amount of gas to balance the gas pressure inside the storage tank, preventing the storage tank from collapsing or expanding, thus protecting the storage tank. When the internal gas pressure is too high, the gas can be quickly released by opening the vent hole, thereby rapidly reducing the gas pressure. In summary, this pyrolysis reactor has the function of controlling the internal pressure of the storage tank.

[0007] Preferably, a door-shaped mounting plate is fixedly connected to the top of the base.

[0008] Preferably, a drive motor is installed below the gate-shaped mounting plate.

[0009] Preferably, the output shaft of the drive motor is welded with a reciprocating lead screw, and a bearing is connected to the top of the reciprocating lead screw.

[0010] Preferably, a screw nut is connected to the outer wall of the reciprocating screw, and the screw nut is welded inside the first connecting block.

[0011] Preferably, a protective cover is fixedly connected to the side of the first connecting block, and a second connecting block is fixedly connected to the side of the protective cover away from the first connecting block.

[0012] Preferably, the second connecting block has a sliding inner hole inside, and a guide rod is slidably connected inside the sliding inner hole.

[0013] The beneficial effects of this utility model are:

[0014] 1. This pyrolysis reactor, capable of controlling the internal pressure of the storage tank, uses a pressure transmitter to detect the pressure in the gas pipeline and feeds the detection results back to the PLC controller. The PLC controller then controls the pressure regulating valve, which adjusts the pressure inside the storage tank. This achieves the effect of controlling the internal gas pressure of the storage tank. When the gas in the storage tank is insufficient or excessive, the breather valve is opened, allowing it to automatically replenish or release a small amount of gas to balance the gas pressure inside the storage tank, preventing the storage tank from collapsing or expanding, thus protecting the storage tank. When the internal gas pressure is too high, the gas can be quickly released by opening the vent, thereby rapidly reducing the gas pressure. In summary, this pyrolysis reactor has the function of controlling the internal pressure of the storage tank.

[0015] 2. This pyrolysis reactor, which can control the internal pressure of the storage tank, is equipped with a protective mechanism. By operating the drive motor, the output shaft of the drive motor drives the reciprocating screw to rotate. When the reciprocating screw rotates, it drives the first connecting block where the screw nut is located to move up and down. When the first connecting block moves, it drives the protective cover to move up and down. When the protective cover moves down to contact the base, the protective cover can cover the pressure regulating valve, the shut-off valve and the control valve inside. This can prevent unauthorized personnel from operating them at will, thereby avoiding the occurrence of production failures. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment of a pyrolysis reactor capable of controlling the internal pressure of a storage tank, comprising a base 1, a storage tank 2 fixedly connected to the top of the base 1, a mounting base 3 fixedly connected to the outer wall of the storage tank 2, a PLC controller 4 mounted on the side of the mounting base 3, a pressure transmitter 5 disposed below the PLC controller 4, a breather valve 6 mounted on the top of the storage tank 2, a vent hole 7 opened on the top of the storage tank 2, a gas pipeline 8 fixedly connected to the top of the storage tank 2, a pressure regulating valve 9 mounted on the outer wall of the gas pipeline 8, a shut-off valve 10 disposed on one side of the pressure regulating valve 9, a control valve 11 disposed on one side of the shut-off valve 10, the shut-off valve 10 being located between the pressure regulating valve 9 and the control valve 11, a sealed container 12 fixedly connected to the end of the gas pipeline 8 away from the storage tank 2, the storage tank 2 being used to store and process materials, and the mounting base 3 being used to mount the PLC controller 4 and the pressure transmitter 5. The C controller 4 is a programmable controller. The PLC controller 4 is connected to the pressure transmitter 5 and the pressure regulating valve 9 respectively. The data value detected by the pressure transmitter 5 can be transmitted to the PLC controller 4, and then the PLC controller 4 controls the pressure regulating valve 9. The pressure transmitter 5 is used to detect the air pressure in the storage tank 2. The breather valve 6 is used to add or discharge a small amount of gas, so that the air pressure in the storage tank 2 can be balanced with the external air pressure, avoiding the situation of the tank expanding or collapsing. The vent hole 7 is used to quickly release gas, which can quickly reduce the air pressure. The gas pipeline 8 is used to transport the gas in the sealed tank 12. The pressure regulating valve 9 is used to regulate the air pressure in the storage tank 2. The shut-off valve 10 is opened for maintenance. At this time, the control valve 11 must be closed. The control valve 11 is used to control the output of gas in the sealed tank 12. The sealed tank 12 is used to store sealing gas, which can provide a source of sealing gas for the storage tank 2.

[0024] Please see Figure 3In this embodiment, a gate-shaped mounting plate 13 is fixedly connected to the top of the base 1; a drive motor 14 is arranged below the gate-shaped mounting plate 13; a reciprocating screw 15 is welded to the output shaft of the drive motor 14, and a bearing 16 is connected to the top of the reciprocating screw 15; a screw nut 17 is connected to the outer wall of the reciprocating screw 15, and the screw nut 17 is welded to the inside of the first connecting block 18; a protective cover 19 is fixedly connected to the side of the first connecting block 18, and a second connecting block 20 is fixedly connected to the side of the protective cover 19 away from the first connecting block 18; a sliding inner hole 21 is opened inside the second connecting block 20, and a guide rod 22 is slidably connected inside the sliding inner hole 21. 13 is used to fix the bearing 16 and the guide slide rod 22. The drive motor 14 is used to drive the reciprocating screw 15 to rotate. When the reciprocating screw 15 rotates, it can drive the first connecting block 18 where the screw nut 17 is located to move up and down. When the first connecting block 18 moves downward, it drives the protective cover 19 to move downward, so that the protective cover 19 can cover the pressure regulating valve 9, the shut-off valve 10 and the control valve 11 inside. This can prevent non-staff members from operating them at will, thereby avoiding the occurrence of production failures. The second connecting block 20 is used to guide the movement of the protective cover 19. The sliding inner hole 21 allows the guide slide rod 22 to slide inside it. The guide slide rod 22 is used to guide the movement of the second connecting block 20.

[0025] During operation, the pressure transmitter 5 detects the pressure within the gas pipeline 8 and feeds the detection result back to the PLC controller 4. The PLC controller 4 then controls the pressure regulating valve 9 to adjust the pressure inside the storage tank 2. This controls the internal gas pressure of the storage tank 2. When the gas in the storage tank 2 is insufficient or excessive, the breather valve 6 opens, automatically replenishing or releasing a small amount of gas to balance the pressure inside the storage tank 2, preventing the storage tank 2 from collapsing or expanding, thus protecting the storage tank 2. When the internal gas pressure is too high... The gas can be quickly released by opening the vent 7, thereby rapidly reducing the gas pressure. When the device is running stably, the drive motor 14 is operated, causing the output shaft of the drive motor 14 to drive the reciprocating screw 15 to rotate. When the reciprocating screw 15 rotates, it drives the first connecting block 18 where the screw nut 17 is located to move up and down. When the first connecting block 18 moves, it drives the protective cover 19 to move up and down. When the protective cover 19 moves down to contact the base 1, the protective cover 19 can cover the pressure regulating valve 9, the shut-off valve 10 and the control valve 11 inside. This can prevent unauthorized personnel from operating them at will, thereby avoiding the occurrence of production failures.

[0026] Through the above steps, by setting up a pressure control device, the pressure inside the storage tank 2 can be effectively controlled. By operating the drive motor 14, the protective cover 19 can be lowered and cover multiple valves, which can prevent unauthorized personnel from operating the valves and thus avoid production failures. This solves the problem that existing pyrolysis reactor storage tanks cannot control the internal pressure and cannot protect multiple operating valves.
