Description

Technical Field

[0001] This utility model relates to the field of pyrolysis reactor technology, and in particular to an anti-clogging type spiral slag discharge machine for pyrolysis reactors. Background Technology

[0002] A pyrolysis reactor is a key piece of equipment used in chemical production for pyrolysis reactions. It is primarily used to decompose large molecules, such as petroleum fractions and plastics, into smaller molecules under high-temperature conditions. This equipment is typically made of high-temperature and corrosion-resistant materials to withstand the harsh conditions generated during the pyrolysis process. In the petrochemical industry, pyrolysis reactors are widely used in the production of basic chemical raw materials such as ethylene and propylene, which are essential components in the manufacture of various chemical products, including plastics, synthetic rubber, and fibers.

[0003] In chemical production, pyrolysis reactors are used to break down large molecules, such as petroleum fractions and plastics, into smaller molecules under high temperatures. However, in actual operation, especially during slag discharge, blockage problems are frequently encountered. The residues from the pyrolysis process typically contain high-viscosity tar, carbon black, and other incomplete pyrolysis byproducts. These substances easily solidify or adhere to the inner wall of the slag discharge pipe after cooling, causing narrowing or even complete blockage. When blockage occurs during slag discharge, material cannot be discharged smoothly, leading to increased pressure inside the reactor and affecting subsequent batches of feed and the reaction process. Therefore, to clear the blockages, production must be stopped periodically for cleaning, which not only reduces equipment utilization but also increases operating costs. More seriously, severe blockages can lead to uncontrolled pressure inside the reactor, posing a risk of explosion or other safety accidents.

[0004] Therefore, it is necessary to design an anti-clogging spiral discharge machine for pyrolysis reactors to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of pyrolysis reactors, which are used to decompose macromolecules into smaller molecules at high temperatures, but whose residues easily cool and solidify or adhere to the pipe walls during slag discharge, causing blockages, affecting material discharge, leading to increased pressure, interfering with subsequent production, requiring frequent shutdowns for cleaning, reducing efficiency and increasing costs, and in severe cases, potentially causing safety accidents, this utility model provides an anti-clogging pyrolysis reactor spiral slag discharge machine.

[0006] The technical solution of this utility model is: a spiral slag discharge machine for an anti-clogging pyrolysis reactor, including a support frame, a discharge pipe and a discharge assembly. Two support frames are symmetrically placed on the ground, and a discharge pipe is fixedly connected between the two support frames. Multiple screw holes are arranged in a ring array on the left side of the discharge pipe. The discharge assembly is provided inside the discharge pipe. It also includes a vibration guide block, an air hammer, a gas supply pipe and a pressure regulating valve. A vibration guide block is fixedly connected to the inclined slide at the bottom of the discharge pipe. Air hammers are symmetrically fixedly connected to the bottom of the vibration guide block. A gas supply pipe is connected and communicates between the bottoms of the two air hammers. A pressure regulating valve is connected and communicates on one side of the gas supply pipe.

[0007] In one embodiment, the right side of the discharge pipe is provided with an inclined slide structure.

[0008] In one embodiment, the support frame on the left is higher than the support frame on the right.

[0009] In one embodiment, the discharge assembly includes a motor, a protective cover, a rotating shaft, gears, and a spiral feeder. The motor is fixedly connected to the support frame on the right side, and the protective cover is fixedly connected to the top of the discharge pipe. The rotating shaft is rotatably connected inside the discharge pipe, and gears that mesh with each other are fixedly connected to the rotating shaft and the output shaft of the motor. Both gears rotate inside the protective cover. A spiral feeder is fixedly sleeved on the rotating shaft, and the outer side of the spiral feeder is in close contact with the inner wall of the discharge pipe and extends to the left out of the discharge pipe.

[0010] In one embodiment, it also includes a top plate, rings and hooks. The top plate is fixedly connected to the upper part of the support frame on the right side. The top plate is located above the right end of the discharge pipe. A rectangular array of rings is fixedly connected to the right side of the top plate, and each ring is hinged with a hook.

[0011] In one embodiment, the system further includes a dust collection frame, a filter screen, a riser, a fan, and an adapter. The dust collection frame is fixedly connected to the top of the top plate, the filter screen is fixedly connected inside the dust collection frame, the riser is connected and communicated to the top of the dust collection frame, the fan is connected and communicated to the middle of the riser, and the adapter is connected and communicated to the top of the riser.

[0012] The beneficial effects are: 1. This utility model uses an inclined discharge pipe and an inclined slide structure to allow waste to be discharged smoothly under the action of gravity; through the linkage between the air hammer, the guide block, the air pipe and the pressure regulating valve, the high-pressure gas drives the air hammer to vibrate, and the guide block transmits the impact force evenly to the inner wall of the discharge pipe, effectively loosening the attached tar, carbon black and other residues and preventing the pipe from being blocked.

[0013] 2. This utility model uses a motor-driven gear transmission to rotate the shaft, which causes the spiral feeder to rotate synchronously in the discharge pipe, thus actively pushing the waste in the pyrolysis reactor, effectively improving the discharge efficiency and continuity. The inclined discharge pipe, combined with the slide structure, allows the waste to be discharged with the assistance of gravity, improving the automation level and discharge stability of the equipment, and also significantly reducing the frequency of manual cleaning and maintenance costs.

[0014] 3. This utility model achieves rapid hanging and precise positioning of waste bags through the combination of top plate, ring and hook, so that the bag opening is aligned with the discharge pipe outlet, ensuring that the waste falls smoothly into the bag; through the synergistic effect of spiral feeding plate and discharge pipe, the waste is continuously and stably discharged and collected in a centralized manner. The whole process does not require continuous manual intervention, realizing efficient and automated operation, improving waste collection efficiency and on-site cleanliness.

Detailed Implementation

[0020] Example: A clogging-resistant spiral discharge machine for a pyrolysis reactor, such as... Figures 1-3As shown, the system includes a support frame 1, a discharge pipe 2, a motor 3, a protective cover 4, a rotating shaft 6, a gear 5, a spiral feed plate 7, a vibration guide block 8, an air hammer 9, an air supply pipe 10, and a pressure regulating valve 11. Two support frames 1 are placed symmetrically on the ground, with the support frame 1 on the left being higher than the support frame 1 on the right. A discharge pipe 2 is welded between the two support frames 1. The right side of the discharge pipe 2 has an inclined slide structure. Multiple screw holes are arranged in a circular array on the left side of the discharge pipe 2. A vibration guide block 8 is installed at the bottom of the inclined slide through screws. Air hammers 9 are symmetrically installed at the bottom of the vibration guide block 8 through screws. Two air hammers... A gas supply pipe 10 is connected and connected between the bottom of the 9. A pressure regulating valve 11 is connected and connected to the side of the gas supply pipe 10 away from the discharge pipe 2. A motor 3 is installed on the support frame 1 on the right side by screws. A protective cover 4 is welded to the top right side of the discharge pipe 2. A rotating shaft 6 is rotatably connected to the left side inside the discharge pipe 2. A gear 5 that meshes with the output shaft of the motor 3 is welded to one end of the rotating shaft 6 extending to the right of the discharge pipe 2. Both gears 5 rotate inside the protective cover 4. A spiral feeding plate 7 is installed on the outer side of the rotating shaft 6 by screws. The outer side of the spiral feeding plate 7 is close to the inner wall of the discharge pipe 2 and extends to the left of the discharge pipe 2.

[0021] When the device is needed, the discharge pipe 2 is securely connected to the pyrolysis reactor via screw holes to ensure sealing and stability. After the pyrolysis reactor completes the pyrolysis process, the generated waste is discharged through the discharge pipe 2. Because the left support frame 1 is higher than the right support frame 1, the discharge pipe 2 is inclined, which helps the waste to slide smoothly to the inclined slide structure on the right side of the discharge pipe 2 under the action of gravity. When a blockage occurs, the operator can control the gas pressure in the gas supply pipe 10 by adjusting the pressure regulating valve 11. High-pressure gas enters the air hammer 9 through the gas supply pipe 10. The air hammer 9 is impacted by the gas and vibrates. These vibrations are transmitted to the discharge pipe 2 through the vibration guide block 8, generating a strong impact force and vibration effect. The vibration guide block 8 evenly distributes and transmits the impact force generated by the air hammer 9 to the inner wall of the discharge pipe 2. This impact... The force can effectively loosen the residues adhering to the inner wall of the discharge pipe 2, preventing them from further solidifying or accumulating, thereby avoiding blockage. The motor 3 is started, and the output shaft of the motor 3 rotates, driving one of the gears 5 to rotate. The two gears 5 mesh and transmit power to the rotating shaft 6. The rotating shaft 6 drives the spiral feeder 7 fixed on it to rotate together. The left end of the spiral feeder 7 extends into the cracking reactor. As the spiral feeder 7 rotates, its threaded structure gradually pushes the waste in the cracking reactor into the discharge pipe 2. The waste moves to the right along the inclined discharge pipe 2 and is finally discharged outside the device through the inclined slide on the right side. If waste adhesion or blockage occurs, the pressure regulating valve 11 can control the air hammer 9 to generate vibration impact, which is transmitted to the inner wall of the discharge pipe 2 to effectively remove the adhering substances and ensure smooth discharge.

[0022] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes a top plate 12, a ring 13 and a hook 14. The top plate 12 is installed on the upper left side of the support frame 1 on the right side by screws. The top plate 12 is located directly above the right side opening of the discharge pipe 2. Four rings 13 are welded in a rectangular array on the bottom right side of the top plate 12, and each ring 13 is hinged with a hook 14.

[0023] like Figure 4 As shown, it also includes a dust collection frame 15, a filter screen 16, a riser 17, a fan 18, and an adapter 19. The dust collection frame 15 is installed on the top right side of the top plate 12 by screws. The filter screen 16 is welded inside the dust collection frame 15. The top of the dust collection frame 15 is connected to and connected to the riser 17. The middle of the riser 17 is connected to and connected to the fan 18. The top of the riser 17 is connected to and connected to the adapter 19.

[0024] The operator unfolds the empty waste bag and hangs its edges on the four hooks 14. After hooking, the waste bag hangs down naturally with the opening open, aligned with the right outlet of the discharge pipe 2 to ensure the waste can fall smoothly into the bag. The spiral feeder 7 pushes the waste out from the right end of the discharge pipe 2, directly into the already hung waste bag below. The waste bag is gradually filled during the discharge process. The entire process requires no continuous manual intervention, achieving automated collection. When the waste bag is full, the operator simply rotates the hooks 14 off the ring 13 to remove the entire waste bag. After removal, a new empty waste bag can be replaced to continue the next stage of discharge operation. If the waste is sticky or prone to clumping, it can be used in conjunction with the air hammer 9 vibration device to ensure smooth discharge and no residue. When the pyrolysis reactor begins to discharge, the spiral feeder 7 pushes... Waste material is discharged along the discharge pipe 2, which may generate a large amount of dust. At this time, the blower 18 is turned on, and the blower 18 generates negative pressure, causing the air carrying dust to be sucked into the riser 17 from above the dust collection frame 15. The dust-laden gas first enters the dust collection frame 15, where larger waste particles or debris are intercepted by the filter screen 16 to prevent them from entering the subsequent pipeline and causing blockage of the riser 17. The filter screen 16 can be disassembled, cleaned or replaced regularly to ensure long-term stable operation of the device. The filtered gas containing fine dust continues to flow upward, and after being pressurized by the blower 18, it enters the riser 17. Finally, through the external pipeline connected by the adapter 19, the dust is transported to the workshop's centralized dust collection system or dedicated dust collection equipment for efficient purification. After the discharge is completed, the blower 18 is turned off. The operating status of the blower 18 and whether the filter screen 16 is blocked are checked regularly to maintain the continuous and efficient operation of the device.
