Description

Technical Field

[0001] This utility model relates to the field of kiln car bottom laying technology, specifically to a kiln car waste coke dust bottom laying device. Background Technology

[0002] In modern industrial production, especially in industries such as steel and building materials, kiln cars, as an important component of heat treatment equipment, play a crucial role in the production process. Kiln cars are widely used in sintering, roasting, and casting processes, undertaking the task of transporting and heating materials in high-temperature environments. Waste coke dust is a byproduct generated during the coking process, mainly originating from the carbonization reaction of coal burned in the coking oven at high temperatures. Coke undergoes a series of chemical reactions and physical changes under high-temperature conditions, eventually forming hard coke particles. However, during the coking process and subsequent transportation and storage, coke will break, producing a large amount of fine coke dust. Waste coke dust is usually a solid particle with a small particle size, large specific surface area, and containing certain harmful substances. By evenly spreading waste coke dust on the bottom of the kiln car, the wear resistance of the kiln car bottom can be effectively improved, ensuring the long-term operational stability of the kiln car.

[0003] The existing method of spreading waste coke dust at the bottom of the kiln car is to pour the waste coke dust into the kiln car and then spread it evenly at the bottom of the kiln car manually. This method is inconvenient to operate and can easily affect the health of workers. Utility Model Content
