Embodiment 1

[0028] Such as figure 1 As shown, the embodiment of the present invention provides a hydraulic coal slime crushing pulper, a pulping structure, which includes: a barrel body 4 erected vertically, its side wall is provided with a slurry overflow port I41, and its top is provided with a cover 6. The lid 6 is provided with a feeding port 61; a screening cylinder 5 is concentrically arranged in the barrel body 4, and a gap is provided between the outer wall of the screening cylinder 5 and the inner wall of the barrel body 4, and the side walls of the screening cylinder 5 are evenly spaced. A plurality of screening holes 51 are arranged in the cloth, and a plurality of crushing heads 152 are evenly distributed on the inner wall of the screening cylinder 5; a hydrocyclone structure for driving the coal slime to rotate is also arranged in the screening cylinder 5; wherein, the hydrocyclone The flow structure includes a driving mechanism 1, the driving mechanism 1 is connected to a ro...

Embodiment 2

[0032] On the basis of Example 1, in order to improve the dispersion effect of the coal slurry and make the particle size in the water-coal slime meet the required requirements, the device has multiple pulping structures, and the size of the screening holes 51 of the multiple pulping structures is different. , and a plurality of pulping structures are arranged in order according to the screening holes 51 from large to small, and the slurry overflow port I41 of the pulping structure with the larger screening holes 51 of each adjacent two pulping structures is smaller than the screening hole 51 The feed port 61 of the pulping structure is connected, and the ore slurry is pumped to the feed port 61 of the pulping structure with a smaller screening hole 51 for further screening and finer particles.

[0033] How this example works

[0034] Same as the pulping process of embodiment 1, the low-moisture water coal slime will be crushed in the first pulping structure first, screened th...

Embodiment 3

[0036] On the basis of Embodiment 1, in order to speed up the crushing efficiency of coal slime and improve the crushing effect, the device also includes a crushing structure 7, which includes a plurality of driving levers arranged above the hydrocyclone cutter head 8, and a plurality of driving levers The rod is evenly distributed on the rotating shaft 3 around the rotating shaft 3, and a plurality of crushing heads II are arranged on the driving rod; wherein, further, a plurality of crushing structures 7 are arranged, and the plurality of crushing structures 7 are uniformly arranged in the axial direction of the rotating shaft 3 On the rotating shaft 3; wherein, the crushing head I52 and the crushing head II are jagged protrusions.

[0037] How this example works

[0038] In order to make the materials in the water-coal slime crush faster, the crushing structure 7 of this device can continuously rotate during the working process, and at the same time combine the crushing hea...

Abstract

The invention relates to a hydraulic coal slime crushing and pulping machine. The hydraulic coal slime crushing and pulping machine comprises a pulping structure, the pulping structure comprises a vertically erected barrel body, the side wall of the barrel body is provided with an ore pulp overflow port I, the top of the barrel body is provided with a cover, the cover is provided with a feeding port, a screening barrel is concentrically arranged in the barrel body, a gap is formed between the outer wall of the screening barrel and the inner wall of the barrel body, a plurality of screening holes are evenly formed in the side wall of the screening barrel, a plurality of crushing heads I are uniformly distributed on the inner wall of the screening cylinder, and a hydraulic cyclone structure used for driving water coal slime to rotate is arranged in the screening barrel. According to the hydraulic coal slime crushing and pulping machine, the crushing and pulping effects are achieved by utilizing rotational flow of water, crushing equipment is not blocked, the pulping effect is good, coal and mud are effectively separated, it is guaranteed that no muddy particles exist in the ore pulp, the pulping effect is further improved, the practicability is high, and the machine is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of coal slime processing, in particular to a hydraulic coal slime crushing and pulping machine. Background technique [0002] According to data released by the National Bureau of Statistics, my country's coal production reached 3.85 billion tons in 2019, and its imports reached 299 million tons. From coal mining to coal washing, my country's annual "solid waste" slime increment reaches about 400 million tons, becoming one of the largest industrial solid "waste" in China. With the continuous release of new coal production capacity and the improvement of mechanized coal mining, the fine-grained coal in raw coal is getting higher and higher. According to authoritative data, it has been shown in production practice that regardless of dense For coal, the separation accuracy of coal slime <3mm is generally poor. Therefore, 20-50% of coal is still contained in these "solid waste" coal slimes, which is difficult...
