Description

Technical Field

[0001] The utility model relates to the technical field of grate coolers, in particular to a grate cooler with adjustable exhaust air volume. Background Art

[0002] Grate cooler is an important main equipment in the clinker burning system of cement plant. Its main function is to cool and transport cement clinker, and provide hot air for rotary kiln and decomposition furnace, etc. It is the main equipment for heat recovery in the burning system.

[0003] According to a grate cooler disclosed in the announcement number: CN219914002U, the application proposes that when the cooling pipe follows the rotation of the driving roller, the end of the cooling pipe can be inserted into the cement raw material on the surface of the conveyor belt. The pressure rod locks the inner cavity of the cooling pipe under the squeezing of the conveyor belt, and the air guide pipe is connected with the exhaust hole. The air pump injects cold air into the cooling pipe through the air equalizing hood, and then enters the cooling pipe. The cold air is injected into the cement raw material layer through the exhaust hole. At the same time, the cement raw material is moved through the cooling pipe, which can quickly release the heat in the cement raw material and improve the cooling effect of the cement raw material. However, its air outlet is fixed, and it is difficult to adjust the air outlet according to the temperature and quantity of the cement raw material. For this reason, we provide a grate cooler with adjustable exhaust volume to solve the above problems. Utility Model Content

[0028] The inner wall of the fixed bin 204 is fixedly connected with a slide bar 208, and the outer surface of the slide bar 208 is slidably connected with four slip rings 207. The outer surface of each slip ring 207 is fixedly connected with two inclined rods 206, and the bottom end of the inclined rod 206 is fixedly connected to the upper surface of the baffle 2014, which can effectively ensure the stability of the baffle 2014 during the reciprocating motion and effectively prevent the baffle 2014 from deflecting during the movement, thereby causing the baffle 2014 to get stuck inside the fixed bin 204, affecting the subsequent normal use of the grate cooler.

[0029] A slide groove 2013 is provided on the upper surface of the grate bed 1, and a slider 205 is fixedly connected to the bottom surface of each baffle 2014, and each slider 205 is slidably connected to the slide groove 2013.
