[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] Example 1

[0033] Referring to Figures 1-8, in this embodiment of the invention, a composite material reactor with high thermal conductivity includes a reactor body 1. A fixing frame 5 is installed at the upper end of the reactor body 1. An upper limiting ring 21 is fixedly installed on the lower side of the fixing frame 5. An upper disk block 22 is rotatably installed at the lower inner position of the upper limiting ring 21. A mixing shaft 18 is fixedly installed on the upper disk block 22. The bottom of the mixing shaft 18 extends through the upper position of the reactor body 1 to the bottom position inside the reactor body 1. Several heating plates 19 are installed at the bottom of the mixing shaft 18 located inside the reactor body 1. A revolution mechanism for driving the mixing shaft 18 to revolve at an inclined position inside the reactor body 1 is provided on the fixing frame 5. A rotation mechanism for driving the mixing shaft 18 to rotate on its own position is provided at the upper position of the reactor body 1. The reactor also includes a circulating heating mechanism. The heating plate 19 is continuously fed into the heating plate by the circulating heating mechanism. With the cooperation of the rotation mechanism and the revolution mechanism, the heating plate 19 rotates on its own axis and revolves around the revolution mechanism, thereby accelerating the stirring of the material inside the reactor and achieving the purpose of rapid heat conduction into the material, which greatly reduces the operating cost of the reactor.

[0034] Several support legs 2 are installed at the bottom of the reactor body 1, and support pads 3 are installed at the bottom of the support legs 2. Through the cooperation between the support legs 2 and the support pads 3, the entire reactor is effectively supported.

[0035] Meanwhile, in order to meet the feeding and discharging needs of the entire reactor, several feed pipes 4 are connected and installed on the upper side of the reactor body 1, and a discharge pipe 16 is connected and installed at the bottom of the reactor body 1. Valves are installed on the feed pipes 4 and the discharge pipe 16 respectively to control the discharge or introduction of materials.

[0036] In order to ensure that the input power source of the revolution mechanism and the rotation mechanism is consistent, thereby reducing the power operation cost of the reactor, the revolution mechanism and the rotation mechanism in this embodiment have their own unique creative ideas.

[0037] The revolution mechanism includes a rotating cylinder 8 fixedly installed on the upper side of the fixed frame 5. A rotating shaft 7 is rotatably installed inside the rotating cylinder 8. A revolution pulley 9 is installed at the bottom of the rotating shaft 7. An eccentric frame 20 is installed at the eccentric position at the bottom of the revolution pulley 9. A heat-conducting cylinder 17 with a hollow structure is fixedly installed on the eccentric frame 20. The heat-conducting cylinder 17 is rotatably installed at the top of the mixing shaft 18.

[0038] When the rotating shaft 7 rotates, the heat-conducting cylinder 17 will be driven to rotate through the eccentric frame 20. Since the entire mixing shaft 18 is inclinedly set inside the vessel body 1, the mixing shaft 18 will drive the heating plate 19 to perform an inclined revolution inside the vessel body 1 under the cooperation of the above structure, thus ensuring the efficient stirring and mixing of materials inside the reactor.

[0039] Meanwhile, in order to ensure the power source for the revolution mechanism, in this embodiment, the fixed frame 5 is an L-shaped structure, and a reaction motor 6 is installed at the top of the fixed frame 5. The output end of the reaction motor 6 is connected to the rotating shaft 7. By directly starting the reaction motor 6, the rotating shaft 7 can be driven to rotate, and finally drive the revolution mechanism and the rotation mechanism to work effectively.

[0040] The rotation mechanism includes a guide frame 25 mounted on the outer wall of the upper limiting ring 21. A drive shaft 27 is rotatably mounted on the guide frame 25. A rotation pulley 10 is fixedly mounted on the upper end of the drive shaft 27. The outer side of the rotation pulley 10 is mounted on a planetary pulley 9 via a connecting belt 11. A drive gear 26 is mounted at the bottom of the drive shaft 27, passing through the guide frame 25. A mixing gear 23, fixed on a mixing shaft 18, meshes with the outer side of the drive gear 26. Through the cooperation of the above structure, the torque on the rotating shaft 7 can be transmitted to the drive shaft 27. Then, with the cooperation of the drive gear 26 and the mixing gear 23, the rotation of the mixing shaft 18 is achieved.

[0041] It should be noted that the mixing gear 23 in this application is installed perpendicular to the axis of the mixing shaft 18. Therefore, the mixing gear 23 rotates at a relative angle during the entire rotation process. In order to ensure that the mixing gear 23 and the transmission gear 26 are always in a meshing state during rotation, in this embodiment, the thickness of the transmission gear 26 is significantly thicker than that of the mixing gear 23.

[0042] In addition, in order to further ensure the tilt stability of the mixing shaft 18 during revolution and rotation, in this embodiment, a lower limiting ring 28 is also installed on the upper side of the vessel body 1, and a lower disk block 24 is rotatably installed inside the upper side of the lower limiting ring 28, and the lower disk block 24 is fixed on the mixing shaft 18.

[0043] During installation, the lower plate 24 and the upper plate 22 are symmetrically mounted on the mixing shaft 18, and their curved surfaces are respectively set inside the corresponding limiting rings. This ensures the tilt angle of the mixing shaft 18 during revolution, further guaranteeing the reliability of the device.

[0044] In this embodiment, the circulating heating mechanism includes a plurality of water inlet holes 29 and water outlet holes 30 disposed on the upper side of the mixing shaft 18. The water inlet holes 29 and water outlet holes 30 are interconnected by heat-conducting pipes 32 disposed inside the heating plate 19. A partition 31 is also installed inside the heat-conducting cylinder 17, which separates the water inlet holes 29 and water outlet holes 30 from each other. The circulating heating mechanism also includes a circulating component.

[0045] The circulation component includes a circulation heating box 14, which is equipped with heating wires. One end of the circulation heating box 14 is connected to a water outlet pipe 12, and the other end is connected to a circulation pump 15, which is connected to the water inlet pipe 13.

[0046] When it is necessary to heat the material inside the reactor, the circulation pump 15 is started. Through the circulation action of the circulation pump 15, the circulating liquid releases heat inside the heating plate 19 and is then reheated inside the circulating heating box 14 before circulating out. This achieves the purpose of efficient heating of the heat inside the reactor body 1. The whole operation process is quick and convenient and is worth promoting.

[0047] It should be noted that in this embodiment, the water inlet 29 and water outlet 30 are arranged in a ring array on the mixing shaft 18, and the water inlet 29 is located below the water outlet 30. The number of the water inlet 29 and water outlet 30 is the same as the number of heating plates 19. Regarding the arrangement of the heat pipe 32, the heat pipe 32 inside the heating plate 19 is arranged in a serpentine bend, while the heat pipe 32 inside the mixing shaft 18 is located on the outer wall as a water inlet channel. This can better ensure that the high-temperature circulating liquid can release heat immediately after entering the mixing shaft 18, further ensuring the heating rate of the reactor.

[0048] Example 2

[0049] To further ensure the heating efficiency of the reactor during production, this invention also provides an embodiment that differs from the previous embodiment in that the heating plate 19 is made of a composite material of graphite, carbon, and carbon fiber. The heating plate 19 made of the above materials has the characteristics of high strength, high thermal conductivity, good wear resistance, strong corrosion resistance, and easy processing.

[0050] The working principle of this invention is as follows: First, the material to be reacted is introduced into the vessel body 1 through the feed pipe 4. Then, the reaction motor 6 is started. With the cooperation of the revolution mechanism and the rotation mechanism, the heating plate 19 is effectively stirred inside the vessel body 1, so that the material can be mixed evenly. During the stirring process of the heating plate 19, with the cooperation of the circulating heating mechanism, the heating plate 19 continuously releases heat inside the material, achieving rapid heating and fast heat conduction, ensuring the rapid reaction of the material inside the reactor. It is worth promoting and using.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
