Problems solved by technology

However, the drying system is complicated, the initial investment is large, the later maintenance cost is high, and the particle size of the treated slime is uneven, and the actual application effect is not ideal.
Most coal preparation plants choose to discharge outside. Long-term stockpiling not only takes up a lot of land, pollutes the environment, but also causes waste of resources

Embodiment Construction

[0021] In order to further understand the invention content, characteristics and effects of the present invention, the following sticky and wet waste is a specific embodiment of coal slime, and in conjunction with the accompanying drawings, the treatment of coal slime as an example is described in detail as follows:

[0022] refer to figure 1 This process includes the traditional sorting filter press, scraper conveying, shearing treatment, conveyor belt conveying, finished material blending, extrusion treatment links,

[0023] refer to figure 2 Coal slime water 2-1 is processed by sorting machine and filter press 2-2 to form coal slime filter cake 2-3. Coal slime filter cake 2-3 has different sizes and large particle sizes. Coal slime filter cake 2-3 It is transported by the scraper to the shearing treatment device 2-4, and after secondary pulverization, the slime filter cake becomes the secondary medium granular product 2-5, and the particle size of the secondary medium gra...

Abstract

The invention relates to a brand-new comprehensive utilization method for clammy waste. According to the method, the clammy waste is sorted and press-filtered into filter cakes, the clammy waste is conveyed to a shear type treatment device in a process system through a scrape conveyor, falling materials smashed through secondary smashing treatment and finished materials are together subjected to the extrusion type treatment process according to the proportion, the materials are directly treated on a production line and transferred without falling to the ground, the materials are pulverized ultimately while fully-mixing is achieved, the waste materials are changed into the treasure on the premise of not lowering the use performance of the finished materials, and economic benefits are increased.

Description

technical field [0001] The invention belongs to the field of environmental protection and energy saving, and in particular relates to a method for comprehensively utilizing sticky and wet waste. The sticky and wet waste is sorted, filtered, sheared, and squeezed to achieve common utilization with finished materials. Turn waste into treasure without reducing the performance of finished materials. Background technique [0002] Sticky waste refers to the muddy discharge generated in production and construction, daily life and other social activities, which basically or completely loses its use value within a certain time and space, and is difficult to recycle and utilize, such as waste slag from sewage treatment , Coal washing sticky wet waste, etc. Taking coal slime as an example, coal slime is a by-product produced during the coal washing process. It is a viscous substance composed of fine coal, pulverized bone stones and water. The coal slime produced by the coal-water mix...
