[0035] The cold water machine for producing papermaking additives in the embodiment can make hot water and flocculants contact uniformly through the installation of the stirring plate 8, make impurities in water coagulate into flocculent, and separate water and flocculent through the cooperation of the filter screen 11, so that the water source can be kept clean, the water source and softening agents can be uniformly mixed through the installation of the softening cylinder 12 and the cooperation of the spiral baffle 13, so that the water source can be softened, and the water source can be pre-cooled by heat dissipation in the process, and the practicability is improved.

[0036] The working principle of the above embodiment is that: first, the external water pump pumps water from the water storage tank 3, which is sent to the refrigerating machine 2 through the pipeline, and then to the heat exchanger 5. In the heat exchanger 5, the cooling water exchanges heat with the refrigerant, and the temperature of the cooling water rises after absorbing heat. The cooling water with a higher temperature is sent to the cooling tower 4 for cooling. In the cooling tower 4, the cooling water exchanges heat and humidity with the air through spraying and air flow, releases heat and lowers the water temperature. The cooled water falls into the cooling tower 4 water collecting tray and is pumped back to the water storage tank 3 by the water pump for the next cycle. When the water source enters the purification cylinder 6 from the pipeline, the external motor drives the rotating rod 7 to rotate. The rotating rod 7 can drive multiple stirring plates 8 to stir the water source in the process of rotating. At this time, the flocculating agent enters the purification cylinder 6 through the first liquid inlet pipe 9 and is fully mixed with the water through the cooperation of the stirring plate 8, so that the impurities in the water can be condensed into flocculation. The rotating rod 7 can drive the auger 10 to transport the water source in the process of rotating. When the water source passes through the filter screen 11, the water and the flocculation are separated, and the flocculation can be discharged from the gap 20 under the cooperation of the auger 10. The purified water source can be discharged into the softening cylinder 12. At this time, the softening agent can enter the softening cylinder 12 through the second liquid inlet pipe 21 and be uniformly mixed with the water source through the cooperation of the spiral baffle 13, so that the water source can be softened and pre-cooled in the process, improving the practicability. The purification cylinder 6 and the softening cylinder 12 are made of heat-conducting materials, which can facilitate heat dissipation and pre-cooling of the water source. The installation of the heat dissipation ring 19 can improve the heat dissipation effect of the purification cylinder 6 and the softening cylinder 12, and improve the pre-cooling effect of the water source. The purified water source can be discharged into the serpentine pipe 14 and sprayed onto the filler 18 from multiple nozzles, and the circulation of the airflow in the cooling tower 4 is realized through the cooperation of the fan 17 to cool the water source. The installation of multiple cooling fins 15 can improve the cooling efficiency of the cooling tower 4 and speed up the cooling speed of the water source sprayed in the cooling tower 4, thereby improving the overall cooling effect.
