[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] See also Figures 1 to 4 In the utility model: a rotary kiln cylinder water spray cooling device comprises a bracket 1, a shell 2 is installed on the bracket 1, a cylinder 3 is installed inside the shell 2, a water tank 4 is fixedly connected to the right side of the bracket 1, two horizontal pipes 5 are connected to the left side of the water tank 4, the left ends of the two horizontal pipes 5 are connected to vertical pipes 6, the outer sides of the two vertical pipes 6 are connected to equidistantly arranged conduits 7, the other ends of the two groups of conduits 7 are connected to the shell 2, a nozzle 8 is installed at the bottom end of the top conduit 7, a water pump 9 is installed on the two horizontal pipes 5, and a refrigerator 10 arranged equidistantly is installed on the back of the water tank 4, the heat dissipation end of the refrigerator 10 is located inside the water tank 4, wherein the refrigerator 10 is a semiconductor refrigeration sheet, the hot end of which is located on the back of the water tank 4, and the cold end is located inside the water tank 4.

[0028] In the utility model, when in use, two water pumps 9 and multiple refrigerators 10 are turned on at the same time. The refrigerator 10 will cool the coolant in the water tank 4. After the coolant is cooled, the water pump 9 at the top will pump the coolant into the vertical pipe 6 through the horizontal pipe 5. The coolant will then be sprayed from the nozzle 8 on the conduit 7 to the surface of the cylinder 3, thereby absorbing the heat generated on the surface of the rotary kiln cylinder 3 to achieve a cooling effect. The coolant that has contacted the cylinder 3 will flow from the bottom conduit 7 into the vertical pipe 6 and the horizontal pipe 5 at the bottom and be pumped into the water tank 4 by the water pump 9, thereby completing the recycling of the coolant.

[0029] See also Figure 4 , wherein: the inner wall of the water tank 4 is fixedly connected with partitions 11 arranged at equal distances, and the partitions 11 are staggered.

[0030] In the present invention, the partition 11 can prolong the contact time between the coolant and the refrigerator 10, thereby improving the cooling effect of the coolant, improving the cooling effect of the rotary kiln cylinder 3, and thus improving the practicability of the device.

[0031] See also Figure 1 , 2 4, wherein: the front side of the partition 11 is interspersed with evenly distributed heat-conducting rods 12, and the front side of the heat-conducting rods 12 penetrates and extends to the front side of the water tank 4.

[0032] In the present invention, the heat-conducting rod 12 can conduct the heat of the coolant received by the partition 11 into the air, thereby improving the heat dissipation effect of the coolant.

[0033] See also Figures 1 to 4 , wherein: an electric push rod 13 fixedly connected to the bottom of the water tank 4 is inserted, a sealing plate 14 is fixedly connected to the top of the electric push rod 13, a sewage outlet 15 is opened on the right side of the water tank 4, and the sealing plate 14 is fixedly connected to a filter plate 16 through two iron plates, and the outer side of the filter plate 16 contacts the inner wall of the water tank 4.

[0034] In the utility model, during the circulation of the coolant, the filter plate 16 can effectively filter the impurities in the coolant to avoid the situation where the impurities are sprayed out and damage the cylinder 3, thereby improving the service life of the cylinder 3. When the machine is shut down, the user can also achieve the self-cleaning effect of the filter plate 16 by turning on the electric push rod 13. After the electric push rod 13 is turned on, the filter plate 16 will be driven to descend. When the highest point of the filter plate 16 is lower than the horizontal tube 5 at the bottom, the drain port 15 will lose the seal of the sealing plate 14, and the coolant in the water tank 4 will pass through the filter plate 16 in the reverse direction, thereby achieving the recoil cleaning effect of the filter plate 16. The dirt at the bottom of the filter plate 16 and the impurities under the recoil will be discharged from the drain port 15, thereby achieving the self-cleaning effect of the filter plate 16 and improving the practicality of the device.

[0035] See also Figure 4 , wherein: the right side of the top of the sealing plate 14 is tilted downward, and the front of the refrigerator 10 is fixedly connected with heat conducting plates 17 arranged at equal distances.

[0036] In the present invention, the inclined setting of the sealing plate 14 can facilitate the discharge of dirt and impurities, and the heat conducting plate 17 can enhance the cooling effect of the refrigerator 10 on the coolant.

[0037] See also Figure 3 , wherein: a mounting plate 18 is fixedly connected to the back of the water tank 4, and fans 19 arranged at equal distances are embedded and installed on the mounting plate 18.

[0038] In the present invention, when the fan 19 is turned on, air is blown toward the hot end of the refrigerator 10, thereby improving the cooling effect of the refrigerator 10 on the coolant and improving the practicality of the device.

[0039] The above are only preferred specific implementations of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
