[0031] When in use, the raw water is first softened through the ion exchanger 1 to remove the hardness ions in the raw water to ensure that the raw water quality meets the use requirements. By softening the water quality, the hardness of the water is reduced and the formation of scale is reduced. The treated softened water is injected into the water tank 2 through the liquid replenishment pipe 7. When the water injection amount in the water tank 2 reaches the set value, the control valve on the liquid replenishment pipe 7 is closed to stop the water injection. Then, under the action of the circulating pump 3, the softened water in the water tank 2 enters the motor cooler 4 through the liquid outlet pipe 8 and the first delivery pipe 9, first cools the motor cooler 4, and then enters the reducer cooler 5 through the second delivery pipe 10 to cool the reducer cooler 5. The cooled water flows back to the water tank 2 through the return pipe 6 to realize the recycling of softened water.

[0032] like Figure 1 and Figure 2 As shown, in this embodiment, a cooling box 11 is also provided, and a plurality of support rods 12 are provided at the bottom of the cooling box 11. The liquid return pipe 6 is a serpentine structure, which prolongs the flow time of softened water between the reducer cooler 5 and the water tank 2 and improves the heat dissipation effect. The liquid return pipe 6 is arranged inside the cooling box 11, and both ends of the liquid return pipe 6 respectively pass through the cooling box 11. A cooling mechanism 13 is provided inside the cooling box 11.

[0033] like Figure 1 and Figure 2As shown, in this embodiment, a plurality of heat dissipation fins 14 are provided on the liquid return pipe 6 to increase the heat exchange area of ​​the liquid return pipe 6 and improve the heat dissipation efficiency of the liquid return pipe 6 .

[0034] like Figure 1 and Figure 2 As shown, in this embodiment, the cooling mechanism 13 includes a driving motor 15, a rotating rod 16 and a plurality of blades 17. The driving motor 15 is arranged at the bottom of the cooling box 11. One end of the rotating rod 16 is connected to the driving motor 15. The other end of the rotating rod 16 passes through the cooling box 11 and extends to the interior of the cooling box 11. The blades 17 are arranged on the rotating rod 16. The top of the cooling box 11 is open.

[0035] When in use, the drive motor 15 is started, the drive motor 15 drives the rotating rod 16 to rotate, the blades 17 rotate synchronously and generate airflow to blow out the hot air emitted by the return pipe 6 and accelerate the cooling of the softened water in the return pipe 6.

[0036] like Figure 1 and Figure 2 As shown, in this embodiment, a dustproof net 18 is provided at the top opening of the cooling box 11 to prevent dust from entering the interior of the cooling box 11 .

[0037] like Figure 1 and Figure 2 As shown, in this embodiment, a liquid level meter 23 is provided in the water tank 2 to facilitate observation of the liquid level height inside the water tank 2 and timely replenishment of softened water into the water tank 1 .

[0038] like Figure 3 As shown, the difference from Example 1 is that, in this embodiment, the cooling mechanism 13 includes a water pump 19, a third delivery pipe 20, a hollow plate 21 and a plurality of nozzles 22, the water pump 19 is installed on the top of the cooling box 11, the hollow plate 21 is arranged at the upper end of the interior of the cooling box 11, one end of the third delivery pipe 20 is connected to the water pump 19, the other end of the third delivery pipe 20 passes through the cooling box 11 and communicates with the hollow plate 21, and a plurality of nozzles 22 are distributed on the hollow plate 21.

[0039] When in use, the cooling water is pumped to the third delivery pipe 20 by the water pump 19, and is delivered to the vacuum plate through the third delivery pipe 20, and is sprayed on the outer side of the return liquid pipe 6 through the nozzle 22. The cooling water and the return liquid pipe 6 are fully in contact and heat exchanged, thereby cooling the softened water inside the return liquid pipe 6. The cooling water is then discharged through the drain pipe at the bottom of the cooling box 11 and recycled.

[0040] The working principle of a cooling device for a scraper conveyor according to an embodiment of the present application is as follows:

[0041] First, the raw water is softened by the ion exchanger 1 to remove the hardness ions in the raw water to ensure that the raw water quality meets the use requirements. By softening the water quality, the hardness of the water is reduced and the formation of scale is reduced. The treated softened water is injected into the water tank 2 through the replenishing pipe 7. When the water injection amount in the water tank 2 reaches the set value, the control valve on the replenishing pipe 7 is closed to stop the water injection. Then, under the action of the circulating pump 3, the softened water in the water tank 2 enters the motor cooler 4 through the outlet pipe 8 and the first delivery pipe 9, first cools the motor cooler 4, and then enters the reducer cooler 5 through the second delivery pipe 10 to cool the reducer cooler 5. The cooled water flows back to the water tank 2 through the return pipe 6 to realize the recycling of softened water. The liquid level height inside the water tank 1 is observed by the liquid level meter 23, so as to facilitate the timely replenishment of softened water into the water tank 1.
