[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] like Figure 1-4 As shown, a boiling cooler with an internal cooling coil includes a boiling cooler shell 15. A feed inlet 12 is provided at the top of the boiling cooler shell 15, and a discharge outlet 13 is provided at the bottom of the boiling cooler shell 15. Material enters the boiling cooler shell 15 through the feed inlet 12, is cooled, and then discharged through the discharge outlet 13. An air distribution chamber 3 is provided at the bottom of the boiling cooler shell 15, and an air distribution plate 5 is provided at the top of the air distribution chamber 3. The air distribution chamber 3 is connected to an air cooler 1 via a cooling fan 14. Cooler 1 cools ambient air. Cooling fan 14 draws cold air discharged from air cooler 1 into boiling cooler shell 15 to cool the material in boiling cooler shell 15. A blower 9 connected to the top of boiling cooler shell 15 is provided on the outside of boiling cooler shell 15. The blower 9 promotes the exhaust of air after the temperature exchange in boiling cooler shell 15. An inner cooling coil 4 is provided on the inner wall of boiling cooler shell 15. 24-degree cooling water is circulated in the inner cooling coil 4, and the material is fully in contact with it for heat exchange and cooling.

[0019] A mixing and discharging device 6 is installed on the air distribution plate 5. The mixing and discharging device 6 rotates under the drive of the drive reducer motor 7. After the material is cooled by heat exchange, it comes into contact with the mixing and discharging device 6 and is discharged to the discharge port 13.

[0020] The drive reducer motor 7 is fixed below the boiling cooler shell 15. The output shaft of the drive reducer motor 7 is connected to the middle of the stirring and discharging device 6 through the drive shaft. The drive shaft passes through the air distribution chamber 3 and enters the boiling cooler shell 15.

[0021] The mixing and discharging device 6 includes a mixing shaft 6-1 and a blade 6-2. Multiple mixing shafts 6-1 are fixedly connected to the connecting shaft 16 in a radiating pattern. Each connecting shaft 16 is provided with a uniformly distributed blade 6-2. The blade 6-2 and the mixing shaft 6-1 have a certain installation angle. The rotation of the mixing shaft 6-1 and the blade 6-2 guides the flow direction of the material so that it flows into the discharge port 13.

[0022] The top of the boiling cooler shell 15 is connected to the dust removal spray tower 10 via an induced draft fan 9. Specifically, the exhaust port of the induced draft fan 9 is connected to the air inlet pipe of the dust removal spray tower 10. The air discharged from the boiling cooler shell 15 enters the dust removal spray tower 10 through the induced draft fan 9 for dust removal. The air outlet of the dust removal spray tower 10 is connected to the clean air exhaust pipeline 11. The dust-removed air is discharged from the clean air exhaust pipeline 11.

[0023] The top of the boiling cooler shell 15 is provided with an end cover, the feed inlet 12 is provided on the end cover, and the end cover is provided with an induced draft pipe connector. One end of the induced draft pipe is connected to the inside of the boiling cooler shell 15 through the induced draft pipe connector, and the other end of the induced draft pipe is connected to the air inlet of the induced draft fan 9. The air discharged from the boiling cooler shell 15 enters the induced draft fan 9 through the induced draft pipe.

[0024] The discharge port 13 is located on the outer side of the bottom of the boiling cooler shell 15, away from the air distribution chamber 3, to facilitate material discharge.

[0025] Air is drawn into the boiling cooler shell 15 through the inlet of cooling fan line 2. Specifically, ambient temperature air first enters the air cooler 1, where it undergoes heat exchange and cooling to below 18 degrees Celsius dew point. Water is then removed by a water-collecting plate inside the air cooler 1, and heated to 20 degrees Celsius by heating steam at the rear end of the air cooler 1. The air is then forced by cooling fan 14 through cooling fan line 2 into the air distribution chamber 3 at the bottom of the boiling cooler shell 15. After entering the air distribution chamber 3, the air is evenly distributed by the air distribution plate 5 and then evenly blown into the interior of the boiling cooler shell 15, interacting with the materials. Contact cooling: After the cold air comes into full contact with the material inside the boiling cooler shell 15, it is discharged upward through the induced draft pipe 8 and the induced draft fan 9 into the dust removal spray tower 10. After being sprayed and dusted in the dust removal spray tower 10, it is discharged through the clean air exhaust pipe 11. While the material is in contact with the cold air, it also comes into full contact with the internal cooling coil 4 inside the boiling cooler shell 15 for heat exchange and cooling. After heat exchange and cooling, the material comes into contact with the stirring and discharging device 6 and is discharged to the discharge port 13. The discharge port 13 is connected to the variable frequency rotary valve conveyor, which can adjust the bed pressure difference (i.e., the material accumulation height) inside the boiling cooler shell 15.
