[0021] The catalytic cracking rotary gas separator is installed inside the dichlorobenzoyl chloride production reaction unit. This rotating mechanism effectively heats the dichlorobenzoyl chloride material within the reaction unit, thereby improving the catalytic cracking efficiency. A stirring and cleaning mechanism is installed on the lower periphery of the rotary gas separator. During rotation, the rotary gas separator drives the stirring and cleaning mechanism, effectively agitating and cleaning the material. To accelerate the reaction speed, a pneumatic gas supply mechanism is installed and connected to the periphery of the catalytic cracking rotary gas distribution mechanism. The pneumatic gas supply mechanism can supply gas to the catalytic cracking rotary gas distribution mechanism and is fixed to the dichlorobenzoyl chloride production reaction mechanism, allowing for stable placement and gas supply. The catalytic cracking rotary gas distribution mechanism can also purge the catalytic cracking stirring and cleaning mechanism, allowing the stirring and cleaning mechanism to expand and protrude to contact the inner wall of the dichlorobenzoyl chloride production reaction mechanism. This effectively scrapes away the deposits on the inner wall of the dichlorobenzoyl chloride production reaction mechanism during rotation, preventing incomplete discharge.

[0022] Reference Figure 1 , Figure 2 and Figure 5The dichlorobenzoyl chloride production reaction apparatus includes a reaction furnace 1, which contains heating elements that generate heat when energized. A power supply cable 11 is fixedly connected to the outer end of the reaction furnace 1, supplying power to the heating elements. This power supply cable 11 is electrically connected to a control unit, and the power supply current can be set via a temperature controller inside the control unit, thus effectively regulating the heating temperature. A solenoid valve discharge pipe 2 is fixedly connected to the lower end of the reaction furnace 1, allowing the dichlorobenzoyl chloride material produced by catalytic cracking inside the reaction furnace 1 to be discharged through the solenoid valve discharge pipe 2. A sealing cover plate 13 is installed on the inner side of the upper end of the reaction heating furnace 1 by screws. The upper opening of the reaction heating furnace 1 can be effectively closed by the sealing cover plate 13. Material addition pipes 5 are fixedly connected through both ends of the sealing cover plate 13. The sealing cover plate 13 facilitates the transportation of dichlorobenzoyl chloride material into the reaction heating furnace 1 for processing and production through the material addition pipes 5. Suspended connecting arm plates 12 are symmetrically fixed to the outer wall of the upper end of the reaction heating furnace 1. The reaction heating furnace 1 can be fixedly installed with the external support through the suspended connecting arm plates 12, so that the reaction heating furnace 1 can be suspended. A catalytic cracking rotary gas distribution mechanism is installed in the middle of the inner side of the sealing cover plate 13. The catalytic cracking rotary gas distribution mechanism can be driven to rotate inside the sealing cover plate 13.

[0023] The catalytic cracking rotary gas distribution mechanism includes a stirring motor 4, which is mounted on the sealing cover plate 13 with screws. The stirring motor 4 can be stably driven. A first coupling 41 is fixedly connected to the output shaft end of the stirring motor 4. When the output shaft of the stirring motor 4 rotates, it can drive the first coupling 41 to rotate. A hollow main shaft 42 is fixedly connected to the lower end of the first coupling 41, which can drive the hollow main shaft 42 to rotate. An air inlet sleeve 45 is fixedly connected to the upper circumference of the hollow main shaft 42, which can drive the air inlet sleeve 45 to rotate. An air inlet slot 44 is opened on the inner side of the outer end of the air inlet sleeve 45. The air inlet sleeve 45 passes through the air inlet slot 44. It can receive external gas, and the gas can be delivered to the hollow main shaft 42 through the inlet sleeve 45. The lower outer wall of the hollow main shaft 42 is symmetrically fixed with a through-hole gas-distributing hollow rod 43. The gas inside the hollow main shaft 42 can be diverted to the gas-distributing hollow rod 43. When the hollow main shaft 42 rotates, it can drive the gas-distributing hollow rod 43 to rotate. The outer ends of the gas-distributing hollow rod 43 and the hollow main shaft 42 are equipped with a catalytic cracking stirring and cleaning mechanism by screws. When the gas-distributing hollow rod 43 and the hollow main shaft 42 rotate, they can drive the catalytic cracking stirring and cleaning mechanism to rotate and stir. A pneumatic gas supply mechanism is installed on the periphery of the inlet sleeve 45. The inlet sleeve 45 can receive the gas delivered by the pneumatic gas supply mechanism.

[0024] Working principle: The dichlorobenzoyl chloride production reaction unit can effectively heat the dichlorobenzoyl chloride material inside, which can effectively improve the efficiency of catalytic cracking. The catalytic cracking rotary gas distribution unit can rotate inside the dichlorobenzoyl chloride production reaction unit. During rotation, the catalytic cracking rotary gas distribution unit can drive the catalytic cracking stirring and cleaning unit to rotate, thereby effectively stirring and accelerating the reaction speed. The pneumatic gas supply unit can supply gas to the catalytic cracking rotary gas distribution unit. The pneumatic gas supply unit is fixed to the dichlorobenzoyl chloride production reaction unit and can be stably placed to supply gas.

[0025] During the discharge cleaning process, the catalytic cracking rotating gas distribution mechanism can purge the catalytic cracking stirring cleaning mechanism, allowing it to expand and protrude to contact the inner wall of the dichlorobenzoyl chloride production reaction mechanism. This effectively scrapes away the deposits on the inner wall of the dichlorobenzoyl chloride production reaction mechanism during rotation, achieving a cleaning effect and preventing incomplete discharge.

Compared with Embodiment 1, the catalytic cracking stirring and cleaning mechanism includes a U-shaped hollow stirring rod 6. A connecting rod 61 is fixedly connected to the middle of the bottom end of the U-shaped hollow stirring rod 6. The connecting rod 61 can drive the U-shaped hollow stirring rod 6 to rotate during rotation. An air inlet connecting pipe 63 is symmetrically and fixedly connected to the inner wall of the upper end of the U-shaped hollow stirring rod 6. The gas in the air inlet connecting pipe 63 can be transported into the U-shaped hollow stirring rod 6. An elastic scraping component is movably installed on the inner side of the upper end of the U-shaped hollow stirring rod 6. The gas input into the U-shaped hollow stirring rod 6 will cause the elastic scraping component to protrude and contact the inner wall of the reaction heating furnace 1. Thus, the elastic scraping component can effectively clean the deposits on the inner wall of the reaction heating furnace 1 during rotation. The elastic scraping assembly includes a T-shaped scraper 62, which is sleeved on the inner side of the upper end of the U-shaped hollow stirring rod 6. The scraper 62 can protrude and is T-shaped, so it will not run out of the U-shaped hollow stirring rod 6 when it protrudes. A damping spring 64 is fixed between the T-shaped scraper 62 and the interior of the U-shaped hollow stirring rod 6. The damping spring 64 can effectively pull the T-shaped scraper 62. When the gas inside the U-shaped hollow stirring rod 6 is discharged, the damping spring 64 can pull the T-shaped scraper 62 to restore its position and align it with the outer end of the U-shaped hollow stirring rod 6. The connecting end rod 61 is installed on the hollow main shaft 42 by screws. When the hollow main shaft 42 rotates, it can drive the connecting end rod 61 to rotate. The air inlet connecting pipe 63 is installed on the air distribution hollow rod 43 by screws. The air inlet connecting pipe 63 can receive the gas delivered by the air distribution hollow rod 43 for delivery.

The other end of the horizontal gas supply pipe 32 is connected to the air inlet wrapping pipe 33. The horizontal gas supply pipe 32 can deliver the gas to the air inlet wrapping pipe 33. The air inlet wrapping pipe 33 has a cross groove 34 in the middle of its interior. The air inlet wrapping pipe 33 can deliver the gas to the cross groove 34. The air inlet wrapping pipe 33 is sleeved on the periphery of the air inlet sleeve 45 through the cross groove 34.
