[0003] Stirring and heating devices generally have a heating function, but the heating component of the stirring and heating device in the prior art is usually arranged on the tank body, which allows the liquid in contact with the tank wall to be fully heated, while the liquid in the middle of the tank cannot be fully heated. Since the heating component is close to the tank wall, the liquid in contact with the tank wall will be heated faster, while the liquid in the center of the tank may be heated slower, which will cause uneven temperature distribution of the liquid and may cause a temperature gradient to form in the tank. Uneven heating may cause temperature differences at different positions of the liquid, thereby affecting the properties and reaction rate of the liquid. The temperature difference may lead to inconsistent product quality.

[0004] Therefore, it is necessary to design a stirring and heating device for high-viscosity liquid to solve the above problems. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-3 The heating component includes a cavity 8 and several heating tubes. The cavity 8 is opened inside the rotating shaft 7. The several heating tubes are fixed on the rotating shaft 7, and the several heating tubes are connected to the cavity 8. Rotary joints 16 are installed at both ends of the cavity 8. The rotary joint 16 at the bottom is connected to the interlayer through a connecting pipe. The staff injects the raw material into the inner tank 4 and energizes the heating wire 5. When the heating wire 5 is energized, it can heat the heat-conducting oil in the interlayer, so that the heat-conducting oil is heated and heated, thereby heating the inner tank 4.

[0023] Reference Figure 1-3The suction assembly includes a box body 9, a capsule 10, a reciprocating screw rod 11, a movable plate 12, two mounting tubes 14 and two one-way valves 15. The box body 9 is fixed to the frame 1, the reciprocating screw rod 11 is rotatably assembled inside the box body 9, the movable plate 12 is threadedly sleeved on the reciprocating screw rod 11, the capsule 10 is placed between the box body 9 and the movable plate 12, one end of the two mounting tubes 14 is connected to the capsule 10, and the two one-way valves 15 are respectively installed on the two mounting tubes 14, one of which is connected to the interlayer, and the other mounting tube 14 is connected to the rotary joint 16 at the top. When the reciprocating screw rod 11 rotates, it can drive the shaft to rotate. When the shaft rotates, the shaft 7 is driven to rotate through the transmission member. During the rotation of the shaft 7 , and several stirring blades thereon stir the material in the inner tank 4. During the rotation of the reciprocating screw 11, since the cross-sections of the box body 9 and the movable plate 12 are both rectangular structures, and the inner surface of the box body 9 and the side surface of the movable plate 12 fit together, the movable plate 12 cannot rotate with the reciprocating screw 11. Therefore, the reciprocating screw 11 can drive the movable plate 12 to move up and down inside the box body 9 when rotating. In this process, the movable plate 12 continuously squeezes and stretches the capsule 10. When the capsule 10 is stretched, the capsule 10 can extract the heat transfer oil in the interlayer, and when the capsule 10 is compressed, the heat transfer oil in the capsule 10 will be pressed into the cavity 8, which makes the heat transfer oil circulate in the interlayer and the cavity 8.

[0024] Reference Figure 1-3 The transmission assembly includes two gears 13 and a shaft. One end of the shaft is axially connected to one end of the reciprocating screw rod 11, and the other end extends to the interior of the inner tank 4. The shaft rod and the rotating shaft 7 are connected through a transmission member. One gear 13 is fixedly sleeved on the shaft rod, and the other gear 13 is fixedly sleeved on the output shaft of the motor 2, and the two gears 13 are meshed with each other. When the staff starts the motor 2, the motor 2 can drive the reciprocating screw rod 11 to rotate through the two meshing gears 13 when it is running.

[0025] Reference Figure 1-3 The flow limiting directions of the two one-way valves 15 are opposite. Specifically, one of the one-way valves 15 limits the airflow to only enter the capsule 10 , and the other one-way valve 15 limits the airflow to only flow out of the capsule 10 .

[0026] Reference Figure 1-3 , several heating tubes are evenly distributed on the rotating shaft 7. Such an arrangement can ensure the heating effect of the several heating tubes on the liquid.

[0027] The specific working principle of this utility model is as follows:

[0028] The staff injects the raw materials into the inner tank 4 and energizes the electric heating wire 5. When the electric heating wire 5 is energized, it can heat the heat-conducting oil in the interlayer, so that the heat-conducting oil is heated and heated, thereby heating the inner tank 4. In addition, the staff starts the motor 2. When the motor 2 is running, it can drive the reciprocating screw 11 to rotate through two mutually meshing gears 13. When the reciprocating screw 11 rotates, it can drive the shaft to rotate. When the shaft rotates, it drives the rotating shaft 7 to rotate through the transmission member. During the rotation of the rotating shaft 7, the several stirring blades thereon stir the material in the inner tank 4. During the rotation of the reciprocating screw 11, since the cross-sections of the box body 9 and the movable plate 12 are both rectangular structures, and the inner surface of the box body 9 and the side surface of the movable plate 12 are in contact with each other, the movable plate 12 cannot rotate with the reciprocating screw 11, so the reciprocating screw 11 When the screw rod 11 rotates, it can drive the movable plate 12 to move up and down inside the box body 9. During this process, the movable plate 12 continuously squeezes and stretches the capsule 10. Since the flow limiting directions of the two one-way valves 15 are opposite, specifically, one of the one-way valves 15 limits the airflow to only enter the capsule 10, and the other one-way valve 15 limits the airflow to only flow out of the capsule 10. Therefore, when the capsule 10 is stretched, the capsule 10 can extract the heat-conducting oil in the interlayer, and when the capsule 10 is compressed, the heat-conducting oil in the capsule 10 will be pressed into the cavity 8, which makes the heat-conducting oil circulate in the interlayer and the cavity 8. After the heat-conducting oil heated by the electric heating wire 5 enters the cavity 8, it will fill the multiple heating tubes, causing the multiple heating tubes to heat up, thereby using the multiple heating tubes to evenly heat the liquid in the inner tank 4.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
