TECHNICAL FIELD
[0001] The utility model relates to a kind of middle feeding polyurethane bottom plate material mould. BACKGROUND
[0002] Previously, coal slime is dried by the way of entering rotary cutting machine from conveyor and then being sent into coal slime dryer, using the crushing device of scraping plate and roller, repeatedly tearing, scraping, scattering, crushing, under the action of induced draft fan, fully contact with high-temperature hot airflow under negative pressure to remove moisture and dry, to achieve the purpose of large amount of coal slime recovery;There is also a way of direct exposure to sun, not only consumes a lot of resources and manpower, but also causes very serious pollution to the environment.
[0003] Therefore, the coal industry gradually began to use filter press to solve this problem, and after the squeezing of ordinary filter press, coal slime still cannot meet the standard of normal use, so the subsequent ultra-high pressure filter press is developed. Ultra-high pressure filter press can directly separate solid and liquid from coal slime because its maximum squeezing pressure can reach 10 megapascals, which converts coal slime into directly usable power coal, significantly reduces the comprehensive investment cost of equipment, and greatly improves and improves the economic benefit and energy saving and environmental protection index of mining area.
[0004] Because the ultra-high pressure filter press has strong squeezing pressure, ordinary high-molecular filter plate cannot withstand it, so the subsequent steel filter plate is developed. Steel filter plate can be applied to ultra-high pressure filter press because of its high hardness and durability.
[0005] At present, steel filter plate mounted on ultra-high pressure filter press has been applied in most coal mines in China, but because it is initially involved in this new field, some problems have been found in practice, such as the weight of traditional steel filter plate is large, which requires very harsh requirements for site foundation, needs additional reinforcement measures, increases cost and construction difficulty; feeding and internal structure need to be optimized, which affects the efficiency of the whole squeezing process and the quality of coal slime, so a kind of middle feeding polyurethane bottom plate material mould is proposed.
