Description

Technical Field

[0001] The present application relates to the technical field of grate coolers, and in particular to a uniform air distribution device for a grate cooler. Background Art

[0002] Grate cooler is an important main machine 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. After the clinker enters the cooler from the kiln, it is spread on the grate plate to form a material layer of a certain thickness. The cold air blown in passes through the material layer moving on the grate bed in perpendicular directions to cool the clinker rapidly.

[0003] However, when the existing grate cooler is in use, the wind enters the wind chamber at the lower end of the grate cooler and flows disorderly in the wind chamber, and there is no way to achieve uniform air discharge, which leads to uneven cooling conditions of cement clinker and affects the quality of cement. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a uniform air distribution device for a grate cooler, which can solve the technical problem that uneven air supply of the grate cooler causes uneven cooling conditions of cement clinker and affects the quality of cement.

[0011] Beneficial effects of the utility model:

[0012] When the utility model is used, the whole device is placed in the air chamber at the lower end of the grate cooler, and the top of the box body is flush with the top of the air chamber, and then the air inlet main pipe is passed through the air chamber to be connected with the fan. When the cement clinker is cooled, the wind generated by the fan flows to the air inlet main pipe, and then flows into the corresponding chamber through the air outlets of each air duct, and then flows out from the through hole, so as to cool the cement clinker transported by the grate plate above the air chamber, and the interior of the box body is divided into a plurality of mutually unconnected chambers by the partition plate, so as to effectively reduce the disordered flow of wind, and the air is discharged through the evenly arranged through holes, so that the air outlet is uniform, the cement clinker is evenly cooled, and the quality of the cement is guaranteed.

When the cement clinker is cooled, the wind generated by the fan flows to the air inlet main pipe 6, and then flows into the corresponding chamber 4 through the air outlet 51 of each air duct 5, and then flows out from the through hole 21, so as to cool the cement clinker transported by the grate plate above the air chamber. The interior of the box body 2 is divided into a plurality of mutually unconnected chambers 4 by the partition plate 3, so as to effectively reduce the disordered flow of wind, and the air is discharged through the evenly arranged through holes 21, so that the air outlet is uniform, the cement clinker is evenly cooled, and the quality of cement is guaranteed.

[0027] like Figure 1 and Figure 2 As shown, each chamber 4 has the same number of through holes 21, so that the air output of each chamber 4 is consistent and the air output is more uniform.

[0028] like Figure 3 As shown, a plurality of air outlets 51 are provided, and the plurality of air outlets 51 are evenly arranged, so that input air is evenly input into the chamber 4 through the air outlets 51 , thereby reducing disordered flow of air in the chamber 4 .

A part of the wind coming out of the fan-shaped air outlet 51 flows directly online, and the other part flows upward after being blocked by the first air guide plate 8 and the second air guide plate 9, and flows out from the through hole 21, which can avoid dead corners of the through hole 21 and reduce wind loss.

[0032] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
