[0018] Please see Figures 1 to 4This utility model provides a technical solution: a safety device for biodiesel distillation production, including a distillation tank 1, with a distillation chamber 2 inside the distillation tank 1. A constant temperature heating plate 16 is installed on the inner wall of the distillation tank 1 and on one side of the distillation chamber 2 to increase the temperature inside the distillation chamber 2, facilitating the heating and distillation of the material. A stirring shaft 3 is rotatably connected inside the distillation chamber 2, and multiple stirring blades 4 are fixedly connected to both sides of the stirring shaft 3. A protective shell 5 is installed on the outer wall of the distillation tank 1, and a motor 27 is installed on the top of the protective shell 5. The output end of the motor 27 is fixedly connected to the stirring shaft 3 through a coupling, driving the stirring shaft 3 and the multiple stirring blades 4 to rotate, stirring the material and making it more evenly heated. The stirring shaft 3 is located on one side and on top of the multiple stirring blades 4. A scraper 35 is installed in the distillation chamber 2, with its edge fitting against the chamber. As the stirring shaft 3 rotates, it scrapes off the deposits on the inner wall of the distillation chamber 2, facilitating cleaning. A feed pipe 28 and a discharge pipe 29 are fixedly connected to one side and bottom of the distillation chamber 2, respectively. A first solenoid valve 30 and a fourth solenoid valve 31 are installed on one side of the feed pipe 28 and discharge pipe 29, respectively, controlling their opening and closing to facilitate the input and output of materials into and out of the distillation chamber 2. A leak detection alarm 6 is installed on one side of the protective shell 5, and a sensor probe 7 is installed inside the shell 5. A wire connects the leak detection alarm 6 and the sensor probe 7, and the wire is protected by a metal sleeve. This double-wall design increases the space for leak collection. In conjunction with the sensor probe 7 and the leak detection alarm 6, it is convenient to promptly alert staff when a leak is detected in the distillation tank 1, which helps to increase safety. A drain pipe 8 is fixedly connected to one side of the protective shell 5 and at the bottom of the leak detection alarm 6. A second solenoid valve 9 is installed on one side of the drain pipe 8. Cooling steel pipes 10 are wound around the outer wall of the distillation tank 1 and inside the protective shell 5. Water inlet pipes 33 and drain pipes 34 are respectively installed on the corresponding sides of the protective shell 5. Water inlet pipes 33 and drain pipes 34 are fixedly connected to both ends of the cooling steel pipes 10. A third solenoid valve 11 is installed on one side of both water inlet pipes 33 and drain pipes 34. One end of water inlet pipe 33 is connected to the water supply equipment, and one end of drain pipe 34 is connected to the wastewater pipe. Cold water can be connected as needed. Cooling the distillation chamber 2 improves its cooling rate and facilitates the maintenance and inspection of the distillation tank 1. An exhaust pipe 17 is fixedly connected inside the distillation tank 1, on the side of the distillation chamber 2 furthest from the feed pipe 28. A condenser 12 is installed on the outer wall of the protective shell 5. A first guide shroud 13 and a second guide shroud 14 are installed on corresponding sides inside the condenser shroud 12. The first guide shroud 13 is fixedly connected to one end of the exhaust pipe 17. Multiple curved condenser tubes 15 are fixedly connected between the first guide shroud 13 and the second guide shroud 14. An outlet pipe 18 is fixedly connected to one end of the second guide shroud 14. The connection of the first guide shroud 13 and the second guide shroud 14 at both ends of the multiple condenser tubes 15 to the exhaust pipe 17 and the outlet pipe 18 respectively facilitates the diversion of steam.Increasing the contact area with cold water and then discharging it through the outlet pipe 18 helps improve its liquefaction efficiency. The inner wall of the condenser 12 has a slot 19, inside which a cooling plate 20 is installed. The cooling end of the cooling plate 20, located inside the condenser 12, is fixedly connected to a metal guide plate 21. Under the action of the cooling plate 20, the water inside the condenser 12 is cooled, which helps ensure the cooling effect of the condenser 12. The heat dissipation end of the cooling plate 20, located outside the condenser 12, is connected to multiple heat dissipation fins 22. A heat dissipation box 23 is installed on one side of the condenser 12, on the outer wall of the multiple heat dissipation fins 22. A fan 24 is installed inside the heat dissipation box 23. Multiple ventilation holes 25 and heat dissipation holes 26 are respectively opened on the adjacent sides of the heat dissipation box 23, which, in conjunction with the operation of the fan 24, facilitates heat dissipation from the multiple heat dissipation fins 22. A control panel 32 is installed on one side of the protective shell 5, located at the bottom of the condenser 12.

[0019] In summary, this biodiesel distillation production safety device operates as follows: During diesel production, the material requiring distillation is fed into the distillation chamber 2 of the distillation tank 1 through the feed pipe 28. The first solenoid valve 30 on the feed pipe 28 is then closed. The constant-temperature heating plate 16 on the inner wall of the distillation tank 1 heats the material, and the motor 27 drives the stirring shaft 3 to rotate, causing multiple stirring blades 4 to heat the material. The generated steam enters the first guide shroud 13 through the exhaust pipe 17 and then flows to multiple condenser tubes 15 for diversion. Simultaneously, the cooling plates 20 in the empty slots 19 of the condenser box 12 cool the water inside. The steam in the multiple condenser tubes 15 liquefies upon cooling and flows to the second guide shroud 14, then is discharged through the exhaust pipe 18 to the liquid collection device. A protective shell 5 is installed on the outer wall of the distillation tank 1. Therefore, when the distillation tank 1 leaks, the liquid enters the protective shell 5. The sensor 7 inside the protective shell 5 detects the liquid, and the leak detection alarm 6 with a signal of TY-YW sounds an alarm to remind the staff. Alternatively, the second solenoid valve 9 on the drain pipe 8 can be opened to discharge the leaked material. When it is necessary to inspect or repair the distillation tank 1, since the outer wall of the distillation tank 1 is wrapped with a cooling steel pipe 10 inside the protective shell 5, and the two ends of the cooling steel pipe 10 are connected to the water inlet pipe 33 and the drain pipe 34 respectively, the third solenoid valve 11 on the water inlet pipe 33 and the drain pipe 34 can be opened in conjunction with the water supply equipment to introduce cold water into the cooling steel pipe 10 to cool the distillation tank 1.
