Description

Dredging device special for coal slime

Technical Field

The utility model relates to a dredging device special for coal slime, in particular to a device of coal mine mining engineering equipment.

Background

The construction of coal mines requires a lot of mine mining equipment. The underground water bin of the coal mine is a necessary facility for underground safe production. The coal mine is flushed with a large amount of groundwater from the rock. In order to ensure normal production, underground water bins need to be built for storing water, and two water bins (main water bin and auxiliary water bin) are built at the same time. Because the underground water of the coal mine contains a large amount of coal blocks, stones and coal slime, the coal slime is precipitated in the water sump, and the water sump coal slime is periodically cleaned when the water sump coal slime is deposited and deposited fully. Most underground water bins of coal mines are cleaned manually, coal slime is flushed into slurry by water on site, and the slurry is pumped to the ground by a slurry pump.

Some dredging devices exist at present, but due to the fact that underground coal mine roadways are narrow and curves are many, the existing coal slime dredging devices are not applicable. The solid and water of the coal slime can not be separated at one time.

The scraper blade and the scraper blade are arranged for dredging. Squeezing the coal slime again by a squeezing method after the coal slime is cleaned, and carrying out solid-water separation on the coal slime. Is a double-pass operation and has low efficiency.

There are also vacuum separation methods. The method is that after the coal slime is washed out by water, the coal slime is pumped into a subsequent vacuum pot by a mud pump to carry out solid-water separation of the coal slime.

The existing manual cleaning method is widely applied to domestic large and small mines. The manual cleaning method has the following defects: on the one hand, the working condition is bad, the labor intensity is high, the workload is large, the efficiency is low, and the labor cost is high; on the other hand, the cleaning period is long, the energy consumption is high, and the danger is high.

There are several ways of dredging the slime, but none are ideal, well-designed equipment. Can not be operated according to the special environment and the requirements of underground coal mine, and can not reduce the moisture content of the coal slime from more than fifty percent to about thirty percent at one time.
