[0034] Implementation Method 1
[0035] Reference Figures 1 to 5 This embodiment, as an optional embodiment of this application, discloses a stirring device, including a stirring tank 1. The stirring tank 1 includes a tank body 101 and a heat insulation cover 102. The tank body 101 is generally cylindrical. A feed inlet 2 is provided at the top of the tank body 101, and a discharge outlet 3 is provided at the bottom. Both the feed inlet 2 and the discharge outlet 3 are provided with regulating valves 4 for controlling their on / off states.
[0036] The heat insulation cover 102 is generally arranged in a circular ring structure and is coaxially sleeved on the outer surface of the box 101; the cross-section of the heat insulation cover 102 is U-shaped and its open end faces the outer surface of the box 101; so as to form a closed heat exchange cavity 5 between the heat insulation cover 102 and the box 101.
[0037] The heat exchange chamber 5 is also provided with a spiral guide plate 103. The spiral guide plate 103 is coaxially arranged with the box body 101. Along the radial direction of the box body 101, the inner side of the spiral guide plate 103 is closely attached to the outer surface of the box body 101, and the outer side of the spiral guide plate 103 is closely attached to the inner wall of the heat insulation cover 102.
[0038] Along the height direction of the housing 101, an inlet pipe 6 communicating with the heat insulation cavity is provided at the top of the heat insulation cavity, and an outlet pipe 7 communicating with the heat insulation cavity is provided at the bottom of the heat insulation cavity.
[0039] The spiral guide plate 103 can guide the heat exchange fluid to flow in an orderly manner within the heat exchange chamber 5, preventing some heat exchange fluid far from the outlet pipe 7 from remaining in the heat exchange chamber 5 for a long time, ensuring that all heat exchange fluid can be effectively discharged, thereby improving heat exchange efficiency. On the other hand, the spiral guide plate 103 can also extend the contact time between the heat exchange fluid and the mixing tank 1, achieving more complete heat exchange, thereby ensuring that the heat exchange fluid can carry away more heat.
[0040] Furthermore, a stirring module is also provided inside the housing 101. The stirring module includes a stirring motor 22 and a stirring shaft 23. A stabilizing frame 25 is provided on the top of the housing 101. The stabilizing frame 25 is generally L-shaped. Its vertical end is connected to the housing 101, and a rolling bearing is provided on its horizontal end. The rolling bearing is connected to the top end of the stirring shaft 23. At the same time, a thrust ball bearing adapted to the stirring shaft 23 is also provided on the housing 101.
[0041] The stirring motor 22 is located on the top of the housing 101, and the stirring motor 22 is connected to the stirring shaft 23 by a power connection.
[0042] The bottom end of the stirring shaft 23 is located inside the housing 101 and is coaxial with the housing 101. Around the axis of the stirring shaft 23, a plurality of stirring paddles 24 are provided on the outer surface of the stirring shaft 23.
[0043] The cooperation between the stabilizer 25 and the housing 101 can effectively improve the stability of the stirring shaft 23 and prevent the stirring shaft 23 from tilting in the radial direction, thereby improving the stability and reliability of the equipment operation.
[0044] Furthermore, the stirring device also includes a circulation module, a heat exchange module, and a controller 8. The circulation module includes a circulation pump 19, and the heat exchange module includes a heat exchange box 11. Along the length of the heat exchange box 11, a first feed pipe 12 is provided at one end of the heat exchange box 11, and a first discharge pipe 13 is provided at the other end. It should be noted that along the height of the heat exchange box 11, the first feed pipe 12 is located at the upper part of the heat exchange box 11, and the first discharge pipe 13 is located at the lower part of the heat exchange box 11.
[0045] Along the width direction of the heat exchange box 11, a second feed pipe 14 is provided at one end of the heat exchange box 11, and a second discharge pipe 15 is provided at the other end;
[0046] The heat exchange box 11 is provided with a plurality of heat exchange tubes 16 and a plurality of spray tubes 17, wherein each heat exchange tube 16 is arranged parallel to the width direction of the heat exchange box 11, and in the height direction, each heat exchange tube 16 is arranged in a plurality of layers; the inlet end of each heat exchange tube 16 is connected to the second feed pipe 14, and the outlet end of each heat exchange tube 16 is connected to each of the second discharge pipes 15.
[0047] Each of the spray pipes 17 is arranged parallel to the length of the heat exchange box 11. Along the height of the heat exchange box 11, each of the spray pipes 17 is arranged in a plurality of positions. In the height of the heat exchange box 11, the heat exchange pipes 16 and the spray pipes 17 of each layer are staggered. The inlet end of each spray pipe 17 is connected to the first feed pipe 12. Along the axis of the spray pipe 17, a plurality of spray heads 18 are also provided on the outer surface of each spray pipe 17.
[0048] The outlet end of the circulating pump 19 is connected to the inlet pipe 6 through the circulating pipe 20, and the inlet end of the circulating pump 19 is connected to the first discharge pipe 13 through the circulating pipe 20; the outlet pipe 7 is connected to the first feed pipe 12 through the return pipe 21.
[0049] During use, cooling water enters through the second feed pipe 14 and exits through the second discharge pipe 15, while high-temperature heat exchange fluid enters through the first feed pipe 12 and exits through the first discharge pipe 13. Inside the heat exchange box 11, the high-temperature heat exchange fluid is sprayed and adheres to the surface of the heat exchange tube 16 in the form of droplets, while flowing to the bottom of the heat exchange box 11 by its own gravity.
[0050] Compared with existing technologies, the heat exchange fluid sprayed in droplet form can dissipate its own heat more quickly, which is beneficial to improving heat exchange efficiency. At the same time, the contact area between the liquid and the heat exchange tube 16 is larger, which is also beneficial to improving heat exchange efficiency.
[0051] Furthermore, a device tube 10 is provided at the bottom of the housing 101. The device tube 10 is connected to the housing 101. A temperature sensor 9 is also provided inside the device tube 10. The device tube 10 is sealed by a plug.
[0052] The stirring device also includes a controller 8, which includes an industrial control computer and a PLC. The industrial control computer is electrically connected to the PLC, and the PLC is electrically connected to each of the regulating valves 4, the temperature sensor 9, the stirring motor 22, and the circulating pump 19.
[0053] The temperature sensor 9 can effectively monitor the temperature inside the mixing tank 1. When the temperature rises, the speed of the circulating pump 19 is increased to increase the flow rate of the heat exchange fluid, thereby increasing the temperature difference between the heat exchange fluid and the mixing tank 1, thus increasing the heat transfer rate and achieving rapid cooling. When the temperature is too low, the reverse operation is performed.
[0054] Compared with the prior art, this application achieves effective control of the temperature of the mixing tank, avoiding the technical problem of the temperature inside the mixing tank continuously rising due to material reaction.
[0055] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
