Description

Technical Field

[0001] The invention relates to the technical field of coal powder processing, in particular to screening equipment for coal powder processing with a dust removal function. Background Art

[0002] Coal powder processing involves multiple links and technologies, covering the entire process from raw coal processing to finished coal powder output, which includes crushing, grinding, drying, screening and other processes. It also involves environmental protection treatment and safe production, and is closely related to energy, industry and other fields. The mined raw coal usually contains impurities and needs to be pre-treated by impurity removal, crushing and other pre-treatment operations. Impurity removal can remove impurities such as gangue in the raw coal and improve the quality of coal powder; crushing is to reduce the particle size of the raw coal for the subsequent grinding process. Generally, it will be crushed to a suitable size according to the initial particle size of the raw coal and the requirements of the grinding equipment. Grinding process: This is the first step in coal powder processing The core link is to grind the pre-treated raw coal into coal powder through a grinding mill. Common grinding mills include ball mills and vertical mills. Ball mills rely on the impact and grinding action of steel balls to grind the coal; vertical mills use the relative movement of grinding rollers and grinding discs to crush and grind the coal, with the characteristics of low energy consumption and high efficiency. Drying treatment: Raw coal usually contains a certain amount of moisture. Excessive moisture will affect the combustion performance and transportation of coal powder, so it needs to be dried. Hot air drying can be used to pass hot air into the coal powder to remove moisture. Therefore, a screening equipment with dust removal function is needed for coal powder processing. There are many problems with existing screening equipment. A large amount of dust will be generated during the screening process. This dust will not only spread in the working environment, seriously affecting the health of operators, easily causing respiratory diseases, but also causing environmental pollution.

[0016] (3) When the operator uses the device of the present invention, he first moves the position of the device through the pulley at the bottom of the device. After moving to the appropriate position, he can add coal powder to the inner wall of the feed port, and it will first fall to the top of the screening plate. Then the operator turns on the vibration motor through the controller, and the vibration motor drives the position of the screening plate to vibrate. The coal powder that passes through the screen will fall to the surface of the inclined plate and then be taken out through the discharge port. At the same time, the coal powder that does not pass through the screening plate will also fall to the surface of the screening plate at the lower position, effectively further processing and screening the coal powder. Finally, the coal powder will fall to the inner wall of the processing bin I and further reach the inner wall of the processing bin.

[0017] (4) The present invention can filter larger particles of dust through the filter plate. After a long time, some dust will accumulate on the surface of the filter plate.

At this time, one end of the extrusion spring is pulled. When one end of the plug rod is separated from the inner wall of the positioning plate to open the positioning groove, the sealing plate and the filter plate can be quickly disassembled, which is convenient for the operator to quickly replace the filter plate.
