Coal slime water is put into the shell 1 from the inlet, sequentially passes through the filter frames 17 from top to bottom, the drive assembly drives the transmission assembly to drive the filter frames 17 to vibrate for screening, and materials intercepted by the filter frames 17 move along the filter frames 17 and are collected after being discharged from the discharge opening 11. The materials passing through the filtering frame 17 are sieved again by the filtering frame 17 below the filtering frame, and the sieving process is repeated to form a multi-stage sieving effect; after the blanking passes through all the filter frames 17, the screened materials (water and coal slime with undersize grain diameter) are gathered at the outlet and flow to the connecting pipe 23 through the guide plate 22, and when the connecting pipe 23 is opened, the control valve can output the screened materials.

From the above description and practice, the present invention provides a mesh screen structure for coal slurry water treatment, which has the following advantages compared with the prior art: adopt above-mentioned a mesh screen structure for coal slime water treatment, through set up a plurality of filter frames in the casing, every will form a screening through once filtering the frame, and then forms multistage screening and improve screening efficiency. The convenient operation of mesh screen structure, reduce operation personnel's working strength, only need drop into the slime water through the import, drive assembly drive transmission assembly drives the vibration of filter frame, can carry out multistage screening to materials such as slime water, the screening is discharged the casing outside from the discharge opening that corresponds by the material of interception each time, get into next screening through the material, and the slime water through all filter frames will be discharged the casing outside from the export.

Those of ordinary skill in the art will understand that: the above description is only for the specific embodiments of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit of the present invention should be included in the protection scope of the present invention.
