Description

Technical Field

[0001] The invention relates to the technical field of coal slag treatment, in particular to coal slag treatment equipment with a filtering structure. Background Art

[0002] Coal slag is a kind of industrial solid waste, which is discharged from coal-fired power plants, industrial and civil boilers and other equipment. It is also called slag. The existing coal slag can be reused after being discharged, and used to make cement, bricks and refractory materials. When the coal slag is reused, it needs to be screened by a coal slag processing device with a filtering structure so that the coal slag can reach the corresponding production size. Therefore, a coal slag processing device with a filtering structure is needed;

[0003] The existing coal slag processing equipment is usually composed of components such as a screen box, a feed port, a primary screen, a secondary screen and a discharge port. The coal slag processing equipment with a filtering structure can pour the coal slag into the interior of the screen box through the feed port when in use. The coal slag will fall onto the primary screen after entering the screen box. The primary screen can screen the coal slag through a vibration device. After the initial screening, the coal slag will fall onto the secondary screen for further screening. After the secondary screen screens the coal slag, it will be discharged through the discharge port. After combustion, the surface of the coal slag will be stained with dust, which will generate a large amount of dust when poured into the screen box. The dust will float into the air through the feed port and cause environmental pollution. The traditional coal slag processing equipment with a filtering structure can collect the dust through a dust suction device, but the dust adhering to the surface of the coal slag is not convenient to collect. When the screen is screening the coal slag, the coal slag is easily stuck in the sieve holes of the screen, which can easily cause the screen to be blocked and affect the screening effect.
