An intelligent cleaning system for coal-water separation in water bunkers

Abstract

The invention discloses an intelligent cleaning system for water sump coal and water separation and belongs to the technical field of coal mine mechanical equipment. The intelligent cleaning system comprises a crane system, a dredging pump, a stirrer, a mud pipeline, a liquid level sensor, an electric control box and a back end processing system. The crane system is suspended above the water levelof an underground water sump through a rail sling, the dredging pump and the stirrer are arranged at the bottom of the crane system, and the crane system drives the dredging pump and the stirrer to move in the up-down direction, left-right direction and front-back direction in the water sump. The dredging pump communicates with the back end processing system located outside the water sump throughthe mud pipeline, and the back end processing system is used for conducting dry and wet separation on coal slurry which is conveyed out and then conveying the coal slurry. The liquid level sensor isarranged on the inner wall of a water retaining dam of the water sump, the liquid level sensor transmits a liquid level signal to a control system in the electric control box, and the control system controls automatic running of the intelligent cleaning system. By means of the intelligent cleaning system for water sump coal and water separation, manual work can be replaced for conducting dredgingon the underground coal mine main water sump, and the automation level and intelligence level of the dredging work are improved.

Description

technical field [0001] The invention relates to the technical field of coal mine machinery and equipment, in particular to an intelligent cleaning system for separating coal from water in a water bin. Background technique [0002] At present, the main method of dredging the underground water tanks of coal mines is manual excavation, that is, after the underground water tanks are full of silt, the excess water must be drained first, and then the workers will use forklifts or dredgers to dig out the deposited silt After being loaded on the rubber-tyred vehicle, it is transported to the designated sludge loading point by the rubber-tyred vehicle, transported to the main belt by the scraper machine, and then transported to the surface. [0003] The dredging scheme of the underground water tank in the prior art mainly has the following disadvantages: 1. The sedimentation speed of the water tank is relatively fast, the dredging work is frequent, the dredging period is long, and mo...

AI Technical Summary

Problems solved by technology

[0003] The dredging scheme of the underground water tank in the prior art mainly has the following disadvantages: 1. The sedimentation speed of the water tank is relatively fast, the dredging work is frequent, the dredging period is long, and more personnel are invested in the dredging operation, and the labor cost of the dredging work is relatively high. stay high

2. The dredging conditions of underground water tanks are complicated, and due to the influence of light and noise, there are great potential safety hazards in the process of dredging

3. Due to the complex composition of the silt in the water tank, dredging will cause great loss to the dredging equipment, increase the cost of maintenance and repair, and the dredging effect is not ideal
