Description

Technical Field

[0001] The utility model relates to the technical field of filter pressing equipment, in particular to an ultra-high pressure filter pressing device for coal slime. Background Art

[0002] Coal slime ultra-high pressure filter press equipment is a kind of equipment for ultra-high pressure filter press of coal slime. Coal slime refers to the semi-solid formed by water in coal powder. It is one of the by-products produced in the current wet coal washing process. The currently developed mature coal slime dehydration processes include hot air drying system, ordinary drum drying method and filter press. Coal slime, as a by-product of coal washing plant, has the unfavorable characteristics of high moisture, high viscosity, high water holding capacity, high ash content and low calorific value. The comprehensive utilization of coal slime has become a big problem. The value of coal slime has not been fully reflected. Drying technology generally cannot directly process concentrated sludge and is dependent on heat source. With the continuous development of science and technology, people have higher and higher requirements for the manufacturing process of coal slime ultra-high pressure filter press equipment.

[0003] When the existing coal slime ultra-high pressure filter press is used for filtration, a filter cloth is arranged on the pressure plate to prevent the pressure plate from directly contacting the coal slime. However, when the coal slime is subjected to ultra-high pressure filtration, although the water in the coal slime can be squeezed out, a small amount of the coal slime after the ultra-high pressure filtration will still adhere to the filter cloth, thereby affecting the next filtration effect and reducing the quality of the coal slime after filtration. Therefore, we propose a coal slime ultra-high pressure filtration press. Utility Model Content
