Problems solved by technology

Although the clean coal products after participation meet the buyer's requirements theoretically, when the buyer checks and accepts the clean coal products, the phenomenon of uneven mixing due to the agglomerated clean coal in the clean coal slime is unavoidable, resulting in The test results show that the ash content of clean coal products is higher than 10%
The buyer’s demanding requirements determine the quality of the entire product based on unqualified products. The above-mentioned agglomerated clean coal obviously cannot meet the needs of buying a house, which will bring troubles to the coal sales of the coal preparation plant, and ultimately have a negative impact on the economy and reputation of the coal preparation plant. Negative Effects

Embodiment Construction

[0035] For ease of understanding, the specific embodiments and operations of the present invention are further elaborated as follows in conjunction with the accompanying drawings:

[0036] The specific structure of the present invention is as Figure 1-6 As shown, it includes an outer casing 10 arranged in a rectangular cylindrical shape after the dehydration process of the filter press. The upper port of the outer casing 10 constitutes the feed port 11 connected to the discharge end of the upper chute on the outside, and the lower port of the outer casing 10 constitutes a Connect the outlet 12 of the feed end of the lower chute to the outside. A stirring part is arranged inside the outer casing 10 to stir the coal slime. The shape of the stirring part is in the shape of a regular square prism frame, including a rotating shaft 21 penetrating through the outer shell 10 and forming a rotation fit with it. The rotating shaft 21 is externally connected to the power output part. ...

Abstract

The invention belongs to the field of mixing and stirring slime water, and in particular relates to a blender. The blender comprises a shell and a stirring part, wherein the shell is provided with a feeding hole and a discharge hole, the feeding hole and the discharge hole are connected fixedly with corresponding inlets and outlets of an upper chute and a lower chute; the stirring part comprises a rotary shaft and a power output part, and the two ends of the rotary shaft are in seal arrangement with matching parts of the shell; parts, close to the two ends, of the rotary shaft are respectively and fixedly provided with a fixing framework, and a mounting hole is formed in each fixing framework; the stirring part further comprises stirring ribs; the stirring ribs are in a tube shape, tube openings of the two ends of each stirring rib are respectively provided with an inner sleeve, the inner sleeves and stirring rib tube cavities form a flexible matching relation with specified travel, and the inner sleeves and the mounting holes are in threaded and fixed connection. The blender has highly effective removal property under a serious slurry environment, and can also effectively avoid the post-period product quality defects caused by agglomeration and adhesion situations when the slurry moves along the conveyance chutes.

Description

technical field [0001] The invention belongs to the field of coal slime water mixing and stirring, and in particular relates to a mixer. Background technique [0002] Coal washing is an indispensable process in coal deep processing. The coal mined directly from the mine is called raw coal. Raw coal is mixed with many impurities during the mining process, and the quality of the coal is also different. Coal with low internal ash content and coal with large internal ash content are mixed together. Coal washing is an industrial process that removes impurities in raw coal, or classifies high-quality coal and low-quality coal. [0003] Due to the long mining life of coal mines, the coal quality changes greatly, and there are many faults and gangue inclusions. Due to large-scale mechanized mining, the content of fine mud increases and the concentration of circulating water is high. In order to reduce the pressure of the slime water system in coal preparation plants, some coal pr...
