After cooling water is introduced, the cooling water enters the water inlet channel 611 through the water inlet 601, then sequentially passes through the water inlet chamber 652 of the fixed tube box 65, the inlet of the cooling water inlet pipe, the cooling water inlet pipe and the outlet of the cooling water inlet pipe, and then enters the floating tube box 64, primary cooling of the shell 1 is achieved in the process, the cooling water entering the floating water tank immediately passes through the inlet of the cooling water outlet pipe to cool the inlet of the water outlet pipe, the cooling water outlet pipe and the outlet of the cooling water inlet pipe, and then enters the water outlet chamber 653 of the fixed tube box 65, secondary cooling of the shell 1 is achieved in the process, and then the cooling water enters the water outlet channel 621 and is discharged through the water outlet 602.
In summary, in the horizontal slag cooler 100 according to the embodiment of the present invention, the supporting mechanism 4 supports the fixed shell 11, and the rotating mechanism 5 drives the fixed shell 11 to rotate, so that the fixed shell 11 can rotate, the feeding mechanism 2 feeds the material into the fixed shell 11, and the material in the fixed shell 11 is cooled by the water cooling mechanism 6. The cooled material is output through the discharging mechanism 3, the area of the feeding mechanism 2 acting with the axial movement shell 12 is sealed under the action of the first sealing mechanism 7, and the area of the discharging mechanism 3 acting with the water cooling mechanism 6 is sealed under the action of the second sealing mechanism 8. When the material is the coal dust that comes out after the pyrolysis coal removes dust, it is when cooling down through horizontal slag cooler 100, has realized sealed in the strict sense, has positive meaning to safety and environmental protection, and the same reason has safety and environmental protection to similar likepowder cooling equally.
The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
