Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of silo cleaning equipment, and more specifically, to a silo cleaning device. Background Technology
[0002] In actual production, it has been found that compared with lump coal and clean coal bunkers, the problem of coal sticking to the walls is more prominent in fine coal bunkers, seriously restricting the improvement of coal mine production capacity. Because the coal lumps in lump coal bunkers are larger in size and spacing, and the coal powder content in clean coal bunkers is lower with relatively larger particles, the coal in lump coal and clean coal bunkers has better fluidity and is less prone to sticking to the walls. Fine coal bunkers, however, have a higher coal powder content and are a sticky granular body with strong binding force. During storage, under certain humidity conditions, fine coal gradually settles and compacts due to gravity. Under compressive stress, the coal body agglomerates into lumps with a certain hardness. As the coal body falls under its own weight, due to the binding properties of the granular body, some fine coal adheres to the bunker walls, creating uneven flow and dead zones. This not only leads to a significant reduction in bunker capacity but also, with prolonged accumulation of fine coal, easily causes spontaneous combustion, posing a major safety hazard. Existing mechanized technologies such as vibrators and loosening machines are only effective for coal bunker wall adhesion under specific conditions and their results are unsatisfactory. Air cannons can only be effective in areas where coal is stuck to the walls and piled up, but the locations of coal stuck to the walls and piled up in coal bunkers are not fixed, so it is impossible to achieve a complete cleaning of the coal bunker.
[0003] Currently, the silo is cleaned manually by using fire hoses. Workers insert long poles with fire hoses into the observation window of the coal feeder to spray water for cleaning. This method involves a large amount of water, makes it impossible to observe the cleaning effect, requires a large number of personnel, and creates a dangerous working environment.
