Technical Field
[0001] This utility model relates to the field of cooling technology for nano-calcium carbonate preparation slurry, specifically a water-cooling device for cooling nano-calcium carbonate preparation slurry. Background Technology
[0002] Most water-cooling devices used for cooling slurries in the preparation of nano-calcium carbonate rely on heat exchangers to transfer heat through solid walls (such as metal pipe walls). In existing water-cooled cooling devices used for cooling slurries in the preparation of nano-calcium carbonate, impurities and minerals in the fluid may deposit on the surface of the heat exchanger during the heat exchange process, forming a scale layer. If not cleaned in time, the thermal conductivity of the scale layer is much lower than that of metal materials, hindering heat transfer and reducing cooling efficiency. Utility Model Content

[0016] like Figures 1-6 As shown, this utility model provides a technical solution: a water-cooled cooling device for cooling slurry in the preparation of nano-calcium carbonate, including a water tank 1. The water tank 1 is connected to the interior of a heat exchanger 4 via a water pipe 5. In order to transport the cooling liquid into the interior of the heat exchanger 4 and store the heated cooling liquid in the water tank 1 for cooling and circulation, the heat exchanger 4 is connected to a hot slurry tank 2 via a water pipe 5, which is responsible for transporting the calcium carbonate slurry that needs to be cooled into the heat exchanger 4. The heat exchanger 4 is connected to a cold slurry tank 3 via a water pipe 5, which is responsible for storing the cooled slurry. The heat exchanger 4 is equipped with a stirrer 6, which is responsible for heat conversion through the metal wall. The outer wall of the heat exchanger 4 is fixedly connected to a stirring device 7, which is responsible for stirring the slurry to prevent the formation of scale. The inner wall of the stirrer 6 is slidably connected to a swinging device 8, which is responsible for stirring the cooling liquid to improve the cooling efficiency.
[0017] The stirring device 7 includes a motor 71, which provides a power source. A heat exchanger 4 is fixedly connected to the outer wall of the motor 71. The output end of the motor 71 is fixedly connected to a drive shaft 72 to transmit the power source. A bushing 73 is slidably connected to the outer wall of the drive shaft 72. One end of a telescopic spring 74 is fixedly connected to the inner wall of the bushing 73. The other end of the telescopic spring 74 is fixedly connected to the drive shaft 72. A stirring blade 75 is fixedly connected to the outer wall of the bushing 73. A conical block 76 is fixedly connected to the inner wall of the stirrer 6. In order to prevent impurities, minerals and other substances in the fluid from depositing on the surface of the heat exchanger 4 and forming a scale layer, which would hinder heat transfer and reduce cooling efficiency, a stirring device 7 is provided inside the heat exchanger 4. The stirring device 7 completes the stirring of the calcium carbonate slurry by the vibration generated by the rotation of the motor 71 and the squeezing of the conical block 76, so as to make the stirring range wider, the stirring effect better, and prevent the formation of scale layer, which would affect the cooling effect.
[0018] Furthermore, the oscillating device 8 includes a slider 81, which slides through the housing of the stirrer 6. A protrusion 82 is fixedly connected to the outer wall of the slider 81, and a rotating rod 83 is rotatably connected to the outer wall of the protrusion 82. A short rod 84 is provided at the end of the rotating rod 83, and the short rod 84 is slidably connected to the inner groove of the stirring plate 85. A rotating shaft 86 passes through the inside of the stirring plate 85, and support plates 87 are fixedly connected to both sides of the rotating shaft 86. A return spring 88 is fixedly connected to the outer wall of the bottom surface of the slider 81, and the bottom of the return spring 88 is fixedly connected to the inner wall of the heat exchanger 4. To avoid maintaining one state for a long time, which would cause the temperature of the cooling liquid near the metal wall to rise, a swing device 8 is provided inside the heat exchanger 4. The agitator plate 85 is oscillated by the squeezing of the stirring blades 75, which can disturb the water flow and stir the cooling liquid that has not been heated to the side near the metal wall, thereby improving the cooling efficiency. Working principle: When the motor 71 is turned on, the transmission shaft 72 and the bushing 73 rotate. When the bushing 73 rotates, it drives the stirring blade 75 to rotate together to achieve stirring. When the stirring blade 75 rotates, it compresses the telescopic spring 74 by squeezing the conical block 76 to achieve the vibration effect. As the stirring blade 75 continues to rotate, it compresses the slider 81, causing the fixedly connected protrusion 82 to move downwards. This causes the rotating rod 83 to move downwards. The end of the rotating rod 83 is connected to a short rod 84, which slides in the internal groove of the stirring plate 85. Therefore, when compressed, the short rod 84 slides downwards, compressing the stirring plate 85. The stirring plate 85 is pierced by a rotating shaft 86 rotatably connected to the support plate 87. Thus, when one end of the stirring plate 85 moves downwards, the other end moves upwards. The bottom end of the slider 81 is fixed with a return spring 88. When the stirring blade 75 misses the slider 81, the return spring 88 returns to its original position, creating a swinging effect.
[0019] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
