A heating device A is mounted on the outer shell. The top of the reaction vessel body is open and fitted with a top cover. A piston plate is disposed inside the reaction vessel body. A linear drive mechanism for driving the piston plate to move vertically is disposed at the bottom of the outer shell. A connecting pipe is disposed between the piston plate and the top cover. A power assembly for driving the connecting pipe to rotate is disposed on the top cover. The connecting pipe has a sealed liquid-oil chamber B. Multiple stirring rods are connected to the connecting pipe. The heating device B is mounted on the top cover. This design provides good heating effect and high heating efficiency, and can easily scrape away residual polymer materials on the inner wall of the reaction vessel, facilitating cleaning and demonstrating strong practicality.

[0004] Existing heating devices cause significant local temperature differences on the sidewalls of the reactor due to uneven material distribution when stirring the inner materials. Furthermore, the reactor cannot maintain a continuous and stable heating effect during use. To address these issues, a polyurea material reactor heating device is proposed. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model embodiment provides a heating device for a polyurea material reaction vessel, such as... Figure 1-5 As shown, the apparatus includes a support frame 1 and a stirring assembly 2. A reactor body 3 is fixedly mounted on the upper end of the support frame 1. The stirring assembly 2 is mounted inside the reactor body 3. A reactor end cap 11 is fastened to the upper end of the reactor body 3. A heating strip 4 is rotatably mounted inside the reactor end cap 11 and is attached to the surface of the stirring assembly 2. A collection chamber 5 is mounted on the outer side of the reactor body 3. A heating unit 6 is mounted inside the collection chamber 5. The heating unit 6 includes a heating body 61, which is fixedly mounted on the outer side of the collection chamber 5. A heating wire 62 is connected to the surface of the heating body 61 and is located inside the collection chamber 5. A heating plate 63 is connected to the heating body 61. The heating unit 6 can heat the airflow inside the collection chamber 5.

[0027] An air-guiding mechanism 7 is provided inside the collection chamber 5. The air-guiding mechanism 7 includes an induced motor 71, which is located outside the collection chamber 5. A push gear 72 is fixedly connected to the output end of the induced motor 71. A push ring 73 meshes with the surface of the push gear 72. An air-guiding ring 74 is fixedly connected to the inner side of the push ring 73. The air-guiding ring 74 is located in the inner cavity of the collection chamber 5 and is above the heating wire 62. Fan blades are provided on the surface of the air-guiding ring 74. The air-guiding mechanism 7 can rotate the air-guiding ring 74, which will push the airflow to rotate inside the reactor body 3 and the reactor end cover 11, so that the hot airflow can be supplied to the reactor evenly and continuously.

[0028] The upper surface of the collection chamber 5 is provided with a pin port 8, and the lower end of the collection chamber 5 is connected to a heating circuit 9. The heating plate 63 is spirally curved and the heating plate 63 is arrayed at the connection position between the collection chamber 5 and the heating circuit 9. The heating plate 63 can heat the airflow entering the heating circuit 9, so that the airflow can evenly distribute the heat to the side wall of the reactor body 3.

[0029] The heating circuit 9 is connected to a first through pipe 10. The first through pipe 10 is located inside the side wall of the reactor cylinder 3. The side wall of the reactor cylinder 3 has a pipe hole. The first through pipe 10 passes through the pipe hole. When the reactor cylinder 3 has a pipe hole on the inside, the first through pipe 10 passes through to the inside, so that heat can be evenly transferred on the surface of the reactor cylinder 3.

[0030] A second through pipe 12 is provided inside the end cap 11 of the reactor. The heating circuit 9 includes a heating pipe 91 and a dispersing ring 92. The heating pipe 91 is connected to the collecting chamber 5. The heating pipe 91 transports the hot air in the collecting chamber 5 to the dispersing ring 92. The dispersing ring 92 transports the hot air to the inside of the first through pipe 10. The heating circuit 9 can connect the collecting chamber 5 and the first through pipe 10, so that the air can rotate and prevent the problem of the temperature dropping after the hot air stops and cannot be heated in time.

[0031] The second through pipe 12 is connected to the first through pipe 10. The upper end of the second through pipe 12 is connected to a return pipe 13. The return pipe 13 is connected to the pin port 8. The return pipe 13 includes a return ring 131 and a return pipe 132. The return ring 131 is connected to the second through pipe 12. The return pipe 132 is located outside the return ring 131 to connect to the pin port 8. The return pipe 13 can cooperate with the second through pipe 12, the first through pipe 10 and the heating circuit 9 to form a closed rotation of airflow, so that the reactor can be heated evenly.

[0032] Working principle: When in use, first put the raw materials into the inside of the reactor body 3, and fasten the reactor end cover 11 to the upper end of the reactor body 3 by connecting the return pipe 132 to the pin port 8. When the stirring component 2 rotates, the heating bar 4 is activated, so that the heating bar 4 rotates with the stirring component 2 and heats the inside of the stirring tank. The heating unit 6 is activated to heat the inside of the reactor.

[0033] By starting the ignition motor 71, the drive gear 72 is rotated, which in turn causes the drive ring 73 to rotate the induced draft ring 74. This causes the airflow inside the collection chamber 5 to be rotated by the induced draft ring 74. The heating body 61 uses the heating wire 62 to heat the airflow inside the collection chamber 5. The hot air is pushed into the heating pipe 91 by the induced draft ring 74. The heating plate 63 inside the heating pipe 91 accurately heats the passing airflow a second time. The heated airflow enters the inside of the first through pipe 10 from the dispersion ring 92, heating the side of the reactor body 3. At the same time, the hot airflow enters the second through pipe 12 along the first through pipe 10 and is discharged into the collection chamber 5 from the return pipe 13, causing the hot airflow to rotate. This ensures that the first through pipe 10 and the second through pipe 12 can continuously and evenly heat the reactor body 3.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
