Description

Technical Field

[0001] This utility model relates to the field of coal and coal slime cleaning technology, specifically a water tank coal slime self-unloading device. Background Technology

[0002] Coal slime is a mixture of fine coal powder and water produced during coal washing and beneficiation. Its characteristics include fine particle size (70%-90% of particles smaller than 200 mesh), high water retention (20%-30% moisture content), high ash content (20%-32% for low-ash, >55% for high-ash), and high viscosity (containing clay minerals, easily turning into mud). These characteristics make it difficult to stockpile and easily cause environmental pollution. With the continuous development of coal mining technology, higher requirements have been placed on the treatment of coal slime. Traditional coal slime treatment methods rely on manual cleaning, which is not only inefficient but also poses safety hazards. Therefore, this application proposes a water-filled coal slime self-unloading device to solve the above problems. Utility Model Content

[0007] Preferably, the chain hoist is manual or electric.

[0008] Preferably, the two filters are installed in two frames, and the two frames are installed in two windows on the side wall of the sedimentation tank.

[0009] Preferably, the length and width of the filter screen are 400*400mm.

[0010] Preferably, the sliding member is provided with pulleys that connect with the sliding grooves on both sides of the channel steel rail.

[0011] (III) Beneficial Effects

[0012] The beneficial effects of this utility model are as follows:

[0013] This type of water tank coal sludge self-unloading device uses a chain hoist to drive the sedimentation tank to rise and fall within the sedimentation pool, allowing the sedimentation tank to be slowly removed from the water tank. By opening the filter screen inside the window, the coal sludge in the sedimentation tank can be cleaned without having to enter the sedimentation pool to clean the coal sludge, thus achieving rapid, efficient, and safe cleaning and discharge of coal sludge.
