Description

Technical Field

[0001] The utility model relates to the technical field of coal mine water filtering, in particular to an energy-saving water filtering device for coal selection and washing. Background Art

[0002] Coal washing is an indispensable process in coal deep processing. It is an industrial process to remove impurities from raw coal or to separate high-quality coal from low-quality coal. After coal washing, it needs to be filtered. The existing water filtering device can cut and separate the coal and mineral materials to prevent the screen gap from being blocked. However, when the material has been blocked in the holes of the screen, the screen bars cannot solve the problem of the blockage and its effect is very limited.

[0003] A Chinese patent discloses an energy-saving water filter for jigging and flotation coal washing (authorization announcement number CN210278476U). This patented technology uses an iron wheel to impact a load-bearing seat, causing the support frame to vibrate, thereby shaking out blockages within the mesh, thereby achieving an anti-blocking effect. Furthermore, the structural design converts the gravity of the falling material into kinetic energy to drive the iron wheel, significantly saving energy consumption.

[0004] However, it has certain disadvantages: it does not have a drying effect, so after the coal is dehydrated, a large amount of water will still adhere to its surface, affecting subsequent coking and other processes. At the same time, the adsorption of water increases the weight of the coal, making transportation difficult. Secondly, water can easily corrode subsequent production equipment. Utility Model Content

[0026] The air hood 14 is directly opposite to the water filter frame 3;

[0027] The fan 11 is used to generate negative pressure and draw air from the outside. The airflow is ejected through the wind hood 14 to reduce the moisture content in the coal and dry the coal, thereby greatly reducing the moisture content in the coal and preventing excessive moisture in the coal from affecting subsequent coking processes;

[0028] The fan 11 is a variable frequency fan with an adjustable speed, which can avoid waste caused by excessive air volume of the fan 11 and also avoid failure to achieve drying effect due to too small air volume, thus having a certain energy-saving function.
