Description

Novel side conveying device for grate cooler

Technical Field

The utility model belongs to the technical field of cement mechanical equipment, especially, relate to a novel side conveying for grate cooler device.

Background

The grate cooler is an important main machine device in the cement production process and mainly used for cooling and conveying cement clinker. The high-temperature cement clinker burned in the rotary kiln is discharged on a grate bed of a grate cooler, a cooling device is arranged below the grate bed, cold air provided by the cooling device upwards penetrates through a moving material layer on the grate bed to take away heat carried by the cement clinker, so that the cement clinker is gradually cooled in the process of moving from the beginning to the end of a grate plate, and the clinker can be cooled to about 60-80 ℃ from 1300 plus 1400 ℃ in a few minutes.

In fact, under the influence of the rotation of the rotary kiln, fine materials can be layered in the process of firing the cement clinker, when the fired cement clinker is discharged on the grate bed, the fine materials can be concentrated on one side of the grate bed, and the rest clinker is concentrated to the other side along with the increase of the particle size. The clinker particles will then follow the movement of the grate plate and thus cover the entire grate bed, and although the particle stratification will vary during the movement, the longitudinal variation is not great. Due to the fact that fine materials on one side are densely stacked and clinker particles on the other side are large, the side clinker is difficult to convey and cannot be conveyed forwards along with the movement of the grate plate in time, and waste of cement clinker is easily caused.

The document of application number 202023075204.1 discloses a grate cooler crank connecting rod device, which comprises an eccentric crankshaft connected to a driving device, wherein one end of the eccentric crankshaft is connected to a driven shaft, and the connecting part of the eccentric crankshaft, a connecting rod and the driven shaft is provided with a self-aligning roller bearing and a sealing assembly. The device can guarantee the smooth operation of the grate cooler and improve the efficiency. However, the device still does not consider the lateral transportation of the clinker, which is easy to cause the waste of the clinker.

The application number 202011561955.6 discloses a push rod type grate cooler pushing device, which comprises a box body, an L-shaped supporting rod, a cross rod and a rotary column, wherein the L-shaped supporting rod is installed inside the box body, a workbench is installed on the rotary column, a rotary rod is connected with a rotary shaft of a motor output shaft, a shifting rod is installed on a fixed shaft, the shifting rod is connected with a convex rod below the workbench in a clamped mode, a cooling chamber is fixed above the box body, and a U-shaped groove plate is installed on the cross rod. The device can greatly ensure the reaction time in the cooling process, thereby improving the cooling quality. However, this device is not optimized for the transport of the side clinker and is inefficient.
