Description

Technical Field

[0001] The utility model relates to the field of cement production, in particular to a grate cooler for cooling clinker. Background Art

[0002] Currently, a Chinese utility model with the announcement number CN218495847U discloses a grate cooler, whose technical solution includes: a base plate and a baffle, a grate cooler body mounted on the top of the base plate, a cylinder mounted on one side of the grate cooler body, a feed pipe embedded in one side of the top of the grate cooler body, support plates welded to the front and rear ends of the feed pipe, two slide grooves formed on opposite sides of the two support plates, sliders mounted to the front and rear ends of the baffle, the sliders at the front and rear ends of the baffle slidingly connected to the slide grooves of the two support plates, second fixing plates welded to the four corners of the bottom of the base plate, four rubber sleeves mounted on the bottom of the four second fixing plates, and four first fixing plates mounted on the bottom of the rubber sleeves. This utility model has the advantage of blocking the top of the feed pipe when feeding is stopped, preventing foreign matter from entering the interior of the grate cooler body through the feed pipe.

[0003] The existing grate cooler has a slow cooling efficiency. Generally, the grate cooler uses a blower to suck the outside air into the grate cooler to cool the clinker. The outside air temperature is high, resulting in slow cooling efficiency, and the outside air temperature changes with the ambient temperature, which makes the cooling efficiency of the grate cooler unstable and difficult to control. It is not convenient for the subsequent production of clinker and does not have a crushing function. Before the clinker enters the grate cooler, there are large pieces of clinker. When the large pieces of clinker are cooled, there may be a temperature gradient inside the large pieces of clinker, that is, the outside has been cooled while the inside is still hot, resulting in uneven cooling and reducing the cooling effect. In addition, the large pieces of clinker are difficult to meet the requirements of subsequent processes and are inconvenient to use. In order to solve the above problems, we propose a grate cooler for clinker cooling. Utility Model Content
