Problems solved by technology

[0004] For impurities suspended in coal water, if the size is large, it is easy to cause adverse consequences after being absorbed by the slurry pump: first, large particles of coal gangue and other impurities enter the pump and are easy to get stuck in the impeller and burn out the motor of the pump; second, large particles The discharge port of impurities such...

Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] Please refer to figure 1 , figure 1 It is a schematic diagram of the overall structure of a specific embodiment provided by the present invention.

[0021] In a specific embodiment provided by the present invention, the crushing mechanism of the coal mine slurry pump mainly includes a multi-stage mixing blade 2 arranged at the water inlet 1 . The mixing knives 2 at all levels are distributed along the axial direction of the water inlet 1. Specifically...

Abstract

The invention discloses a pulverizing mechanism of a coal mine slurry pump, which comprises multi-stage mixing knives arranged at the water inlet and freely rotatable, the mixing knives at each level are distributed along the axial direction of the water inlet, and The stirring knives all include a plurality of blades that are evenly distributed in the circumferential direction and are used to strike coal water impurities when rotating at high speed. The crushing mechanism disclosed in the present invention rotates at a high speed during operation, so that the coal water impurities are graded and crushed in the process of passing through the water inlet, and the size is rapidly reduced. When finally reaching the coal mine slurry pump, the particles of coal water impurities are enough Small and able to pump smoothly. Therefore, when the coal mine slurry pump discharges the coal water at the low-lying point of the coal mine site, the suspended impurities (such as coal gangue, etc.) can be classified and crushed to reduce the particle size of the entrained particles in the sewage and reduce the probability of pipeline blockage accidents. Improve pump operating efficiency. The present invention also discloses a coal mine slurry pump comprising the crushing mechanism, and its beneficial effect is as above.

Description

technical field [0001] The invention relates to the technical field of industrial and mining equipment, in particular to a crushing mechanism of a coal mine slurry pump. The present invention also relates to a coal mine slurry pump comprising the above crushing mechanism. Background technique [0002] With the development of China's machinery industry, more and more industrial and mining equipment are also widely used. [0003] Slurry pump is a kind of common mechanical equipment in coal mine production enterprises. Relying on the negative pressure formed by the high-speed rotation of the pump impeller, it drives the flow of impurities such as water and coal gangue suspended in the water, and transfers the water and impurities such as coal gangue entrained in the water. . During this process, the particle size requirements for impurities such as coal gangue suspended in the water are relatively strict, and only impurities that meet the specified size can be successfully ab...
