[0017] 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.

[0018] like Figures 1 to 3As shown, a heat transfer oil reactor with self-cleaning function includes a cylindrical body 1. Two independent stirring shafts 2 are arranged parallel to each other inside the cylindrical body 1. One end of each stirring shaft 2 extends axially out of the cylindrical body 1 and is connected to a gearbox 7. The gearbox 7 is mounted on a support frame 13 by fixing screws 12, and the two are fixedly connected by a threaded connection. This installation method ensures that the gearbox 7 will not shift or loosen during operation. Multiple stirring discs 3 are evenly spaced on the two stirring shafts 2. These stirring discs 3 have a disc-shaped structure, and multiple stirring teeth 4 are evenly distributed along the circumference of each stirring disc 3. These stirring teeth 4 are arranged radially. To further enhance the stirring effect, each stirring tooth 4... At the end of the device, blades 5 are fixedly installed. These blades 5 are inclined at a certain angle to the stirring teeth 4, thereby forming an efficient material flow during the stirring process. The top of the blades 5 contacts the inner wall of the cylinder 1. This design can effectively remove various materials adhering to the inner wall of the cylinder 1, ensuring that the inside of the cylinder 1 is always clean. At the same time, the top of the blades 5 also adopts a contact structure that matches the surface of the stirring shaft 2. This double contact design can not only clean the inner wall of the cylinder 1, but also simultaneously remove materials that may accumulate on the surface of the stirring shaft 2, thereby achieving a comprehensive cleaning function for the entire stirring device. This structural design greatly improves the self-cleaning ability of the equipment and effectively avoids the problem of cross-contamination caused by material residue.

[0019] like Figures 1 to 3 As shown, the mixing plate 3 is provided with five mixing teeth 4, and each of the five mixing teeth 4 is provided with a slot, and the blade 5 is installed in the slot.

[0020] Furthermore, five stirring teeth 4 are evenly distributed on the circumferential edge of the stirring plate 3. These stirring teeth 4 are arranged at equal angles, and each stirring tooth 4 has a slot on its top. A blade 5 is fixedly installed in each of these slots. This structural design enables the five stirring teeth 4 and their matching blades 5 to work together during the stirring process, thereby improving stirring efficiency and uniformity. like Figures 1 to 3 As shown, the stirring teeth 4 on the two stirring shafts 2 are arranged in an alternating manner and the stirring teeth 4 mesh with each other to clean the tooth surface.

[0021] Furthermore, the stirring teeth 4 are arranged in an alternating manner on the two stirring shafts 2, that is, the stirring teeth 4 on one stirring shaft 2 are staggered from the stirring teeth 4 on the other stirring shaft 2. The stirring teeth 4 on the two adjacent stirring shafts 2 can mesh with each other during rotation. This meshing structure can not only improve the stirring efficiency, but more importantly, it can effectively clean the working surface of the stirring teeth 4 through the mutual scraping action between the stirring teeth 4, and prevent material residue and accumulation. like Figures 1 to 3As shown, a motor 8 is provided on one side of the gearbox 7. One end of the output shaft of the motor 8 is keyed to a first pulley 9. A second pulley 10 is connected to the gearbox 7. A belt 11 is connected between the first pulley 9 and the second pulley 10 for transmission.

[0022] Furthermore, a motor 8 is fixedly installed on one side of the gearbox 7. The output shaft of the motor 8 is connected to the first pulley 9 via a key connection. A second pulley 10 that mates with the first pulley 9 is connected to one side of the gearbox 7. O-grooves are machined on the outer circumferential surfaces of the first pulley 9 and the second pulley 10, respectively. A belt 11 with appropriate tension is fitted into the O-grooves of the two pulleys, thereby forming a reliable belt drive connection. This transmission arrangement can effectively transmit the power of the motor 8 to the gearbox 7, while also having certain buffering and overload protection functions. like Figures 1 to 3 As shown, a support leg 6 is installed on the bottom surface of the cylinder 1, and the support leg 6 is installed on the support frame 13 by fixing screws 12.

[0023] Furthermore, multiple support legs 6 are evenly distributed around the bottom circumference of the cylinder 1. These support legs 6 ensure the stability of the overall structure. Each support leg 6 is connected to the fixing screw 12 by a threaded connection to achieve a fixed connection. This connection method can effectively prevent loosening that may occur during equipment operation. The support frame 13 has high load-bearing capacity and anti-deformation performance, thereby ensuring that the entire cylinder 1 remains stable during operation. like Figures 1 to 3 As shown, a fixing screw 12 is installed on the bottom surface of the gearbox 7, and the gearbox 7 is fixedly installed on the support frame 13 by the fixing screw 12.

[0024] Furthermore, one end of each of the two stirring shafts 2 is connected to the output shaft of the gearbox 7. The gearbox 7 is equipped with a gear set and a speed regulating mechanism. When the motor 8 starts, the output shaft of the motor 8 drives the first pulley 9 to rotate. The first pulley 9 transmits power through the belt 11, thereby driving the second pulley 10 to rotate. The rotation of the second pulley 10 drives the gear set inside the gearbox 7 to rotate. The rotation of the gear set drives the two connected stirring shafts 2 to rotate together, thereby realizing the stirring function. The speed regulating mechanism can adjust and control the rotation speed of the two stirring shafts 2 according to the process requirements. This design not only ensures the synchronicity and stability of the stirring shafts 2, but also enables flexible switching of different speeds, thereby meeting the requirements of different material stirring conditions.

[0025] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
