[0023] like Figures 1 to 3 The main structure of a cooling device for heavy calcium carbonate processing shown in the figure is a bottom plate 1, a cooling cylinder 2 is fixedly connected to the top surface of the bottom plate 1, a thermometer 18 is fixedly connected to the outer wall of the cooling cylinder 2, and the thermometer 18 can monitor the temperature of the heavy calcium carbonate inside the cooling cylinder 2 in real time, a feeding door 3 is sealed and hinged on the side wall of the cooling cylinder 2, an air outlet is opened on the top surface of the cooling cylinder 2, and a filter is fixedly connected to the inside of the air outlet, and the filter is used to prevent the heavy calcium carbonate powder inside the cooling cylinder 2 from being discharged through the air outlet;

[0024] The top surface of the cooling cylinder 2 is fixedly connected to a liquid nitrogen box 4, and the top surface of the liquid nitrogen box 4 is fixedly connected to an air inlet pipe 6, and the air inlet pipe 6 extends to the interior of the cooling cylinder 2 and is fixedly connected to an annular tube 7, and the annular tube 7 is provided in multiples, and a connecting pipe 8 is fixedly connected between each annular tube 7, and an exhaust pipe 9 is fixedly connected to the side wall of the lowest annular tube 7, and the end of the exhaust pipe 9 extends to the outside of the cooling cylinder 2 and is connected to the liquid nitrogen box 4, so that the liquid nitrogen can circulate in the annular tube 7. Because the annular tube 7 is provided in multiples, and the multiple annular tubes 7 are connected through the connecting pipe 8, the liquid nitrogen can fully flow into the interior of each annular tube 7, and then the liquid nitrogen will be discharged to the interior of the liquid nitrogen box 4 through the exhaust pipe 9 fixedly connected to the side wall of the lowest annular tube 7, so that the liquid nitrogen circulates in the annular tube 7 and the connecting pipe 8, so that the cold air is released into the interior of the cooling cylinder 2 through the outer wall of the annular tube 7;

[0025] A circular groove 10 is provided on the top surface of the bottom plate 1, and a hollow disk 12 is rotatably connected in the circular groove 10. A sealing ring 17 is fixedly sleeved on the outer wall of the hollow disk 12. The outer side of the sealing ring 17 sleeved on the outer side of the hollow disk 12 is sealingly slidably connected to the inner wall of the circular groove 10, and a plurality of air outlet pipes 13 are fixedly connected to the top surface of the hollow disk 12. A one-way valve 14 is fixedly installed inside the plurality of air outlet pipes 13. Since the one-way valve 14 is fixedly connected inside the plurality of air outlet pipes 13, it is possible to effectively prevent heavy calcium carbonate from entering the hollow disk 1 through the air outlet pipe 13. 2, a motor 11 is fixedly installed at the lower end of the circular groove 10, and the rotating shaft of the motor 11 is fixedly connected to the lower end of the hollow disk 12, and a rotating tube 5 is fixedly connected to the center of the top surface of the hollow disk 12, and the upper end of the rotating tube 5 is connected to the air pipe 15 through a sealed rotating joint.

[0027] How it works

[0028] When the cooling device for heavy calcium carbonate processing is used, the heavy calcium carbonate to be cooled is firstly put into the cooling cylinder 2 through the feed door 3 sealed and hinged on the side wall of the cooling cylinder 2, and then the liquid nitrogen inside is passed into the inside of the air inlet pipe 6 through the liquid nitrogen box 4, and then the liquid nitrogen is passed into the inside of the annular tube 7 arranged inside the cooling cylinder 2 through the air inlet pipe 6. At this time, because the annular tubes 7 are arranged in plurality, and the plurality of annular tubes 7 are connected through the connecting pipe 8, the liquid nitrogen can fully flow into the inside of each annular tube 7, and then the liquid nitrogen will be discharged to the inside of the liquid nitrogen box 4 through the exhaust pipe 9 fixedly connected to the side wall of the lowest annular tube 7, so that the liquid nitrogen circulates in the annular tube 7 and the connecting pipe 8, so that the cold air is released into the inside of the cooling cylinder 2 through the outer wall of the annular tube 7;

[0029] Then, the high-pressure gas can be passed into the interior of the hollow disk 12 through the air supply pipe 15, and then sprayed into the heavy calcium carbonate through the multiple air outlet pipes 13 on the top surface of the hollow disk 12. At this time, because the multiple air outlet pipes 13 are fixedly connected with the one-way valves 14, the heavy calcium carbonate can be effectively prevented from entering the interior of the hollow disk 12 through the air outlet pipe 13. At this time, because the heavy calcium carbonate is in powder form, it can be easily blown up. Then, the motor 11 is started, and the hollow disk 12 fixedly connected at the end of its rotating shaft is driven by the motor 11 to rotate. At the same time, because the rotating pipe 5 on the top surface of the hollow disk 12 is connected to the air supply pipe 15 through a rotating sealing joint, the air supply pipe 15 will not affect the rotation of the hollow disk 12 while also being able to pass air into the interior of the hollow disk 12, so that the heavy calcium carbonate can be blown up more evenly. At this time, the blown heavy calcium carbonate powder will fully contact with the cold air released by the annular tube 7 and cool down quickly.
