Description

Technical Field

[0001] The utility model relates to the technical field of cement feeding devices, and specifically relates to a clinker feeding device for cement production and processing. Background Art

[0002] Cement is an important building material in modern society. Cement clinker takes limestone, clay, and iron-containing raw materials as the main raw materials, is prepared into raw meal in appropriate proportions, burned to partial or complete melting, and obtained semi-finished products after cooling. In production, dry and wet methods are often used for preparation. Among them, in the wet method preparation, the raw materials are ground into raw meal slurry with water and then put into a wet rotary kiln to be calcined into clinker, forming clinker particles of different sizes.

[0003] Chinese Patent with publication number CN117065881A discloses a clogging-preventing and easy-to-clean clinker feeding device for cement production, including a hopper. A cover plate is sleeved on the top of the hopper. A feed pipe is connected to the top of the cover plate. A discharge pipe is connected to the bottom of the hopper. A clamping and locking mechanism is installed between the hopper and the cover plate. Lifting mechanisms are fixedly installed on both sides of the cover plate. A crushing and conveying mechanism is installed through the top of the cover plate. A water source flushing mechanism is installed through the bottom of the cover plate. The present invention locks the cover plate on the top of the hopper, facilitating the disassembly between the cover plate and the hopper, exposing the crushing mechanism, facilitating the cleaning of the inner wall of the hopper and the crushing structure. The crushing rod and the stirring rod rotate to crush the materials entering the inner cavity of the hopper, with good crushing effect. At the same time, the materials adhering to the inner wall of the hopper are scraped off, and the crushed clinker is evenly conveyed downward, facilitating the downward flow of the clinker.

When the clinker particles are relatively large, the rotation of the crushing rod in the hopper is blocked and it is not convenient to use. At the same time, the crushing rod and the stirring rod are prone to damage. Content of the Utility Model
