[0022] like Figure 1 As shown, the roller cooling structure of the grate cooler provided by the utility model includes a roller body 10, an air inlet assembly 20 and an air outlet assembly 30. The air inlet assembly 20 is movably connected to one end of the roller body 20, and the air outlet assembly 20 is arranged on the roller body 10. The air inlet assembly 20 can introduce air into the roller body 10, and the air outlet assembly 30 can discharge the air in the roller body 10. Through air convection heat exchange, the roller body 10 is continuously cooled and cooled, thereby avoiding the roller body 10 from being overheated, avoiding the roller body 10 from failing due to continuous high temperature, and avoiding affecting the normal operation of the grate cooler.

[0023] The roller body 10 is cylindrical and has a hollow groove 11 thereon. The hollow groove 11 is arranged along the length direction of the roller body 10 so that one end of the roller body 10 is open and the other end is closed, thereby ensuring that the air convection heat exchange process proceeds normally.

[0024] The air intake assembly 20 includes an air intake pipe 21, a connecting seat 22, and a blower 23. The air intake pipe 21 is arranged in the hollow groove 11.
