The working principle is as follows: in the process of using the integrated dust-settling purification device for the underground coal mine, firstly, the negative pressure fan set 4 is opened to enable the interior of the dust-settling purification pipe 1 to generate negative pressure, air containing coal dust generated in the coal mining process is sucked into the dust-settling purification pipe 1, and the dust-settling purification device and the activated carbon purification plate 3 in the dust-settling purification pipe 1 are utilized to filter and purify the gas containing the coal dust;
when using the first scheme for dustfall purification:
the contact area between the filter screen and the gas is enlarged by utilizing the spherical surface of the spherical filter screen 202, the filtering effect on the coal dust is improved, and when the gas after the coal dust is filtered passes through the activated carbon purification plate 3 again, harmful substances in the gas are absorbed by utilizing the activated carbon purification plate 3;
when more coal dust is adhered to the spherical surface on one side of the spherical filter screen 202, the coal dust on the spherical filter screen 202 needs to be scraped, at the moment, the upper fan 403 of the negative pressure fan set 4 is controlled to rotate forwards, the lower fan 404 rotates backwards, so that the upper part of the spherical filter screen 202 is acted to one side of the negative pressure fan set 4, and the lower part of the spherical filter screen 202 is acted to the opposite action force, so that the spherical filter screen 202 rotates in the fixed rotating seat 201 under the action of the supporting balls 203;
when the spherical filter screen 202 rotates, the coal dust adhered to the surface of the spherical filter screen 202 is removed by the dust removing cone 204, when the dust removing cone 204 contacts the coal dust adhered to the spherical filter screen 202, the adhered coal dust generates a downward acting force on the dust removing cone 204, at this time, the pressing spring 208 can be used for buffering, when the dust removing cone 204 moves downward, the linkage rod 210 and the telescopic rod 212 are driven to move downward, at this time, because one end of the telescopic rod 212 is hinged, and the telescopic rod 212 and the linkage rod 210 are arranged at ninety degrees, the telescopic rod 212 can drive the dust blocking plate 206 to move downward, at this time, the telescopic rod 212 extends, a certain gap is generated between the dust blocking plate 206 and the first dust collecting hopper 205, the coal dust removed by the dust removing cone 204 can enter the first dust collecting hopper 205 through the gap between the dust blocking plate 206 and the first dust collecting hopper 205, the collection of the shoveled coal dust is completed, when the shoveling cone 204 does not shovel the coal dust, the extrusion spring 208 is not extruded, the shoveling cone 204 restores to the original position, the linkage rod 210 and the telescopic rod 212 are driven to restore to the original position, at the moment, the dust blocking plate 206 with one hinged end seals the first dust collecting hopper 205 again, and the collected coal dust is prevented from being sucked from the first dust collecting hopper 205 under the action of negative pressure;
when the spherical filter screen 202 after the coal dust is scraped rotates to the position of the supporting ball 203, a small amount of coal dust falls into the dust collection cavity 213 due to the mutual contact between the spherical filter screen 202 and the supporting ball 203, and at this time, the small amount of coal dust can be discharged through the dust discharge hole 214;
when using the second scheme for dustfall purification:
the gas containing coal dust entering the dust-settling purification pipe 1 is filtered by the first filter screen plate 2-8, at the moment, the first filter screen plate 2-8, the rotating ring 2-7 and the fixing ring 2-2 are subjected to acting force towards one side of the negative pressure fan set 4 due to negative pressure generated by the negative pressure fan set 4, so that the first shaking spring 2-3 is compressed, and the second shaking spring 2-4 is stretched;
when more coal dust is adhered to one side of the first filter screen plate 2-8, the normal work of the negative pressure fan set 4 is stopped, at the moment, the rotating handle 2-10 is held by hand, the exhaust valve 2-17 in the rotating handle 2-10 is deformed, the exhaust valve clack 2-18 is opened, at the moment, the gas in the sealed and fixed air bag 2-14 is exhausted through the exhaust pipe 2-16 and the exhaust valve 2-17, the sealed and fixed air bag 2-14 is contracted, the fixing between the fixed ring 2-2 and the rotating ring 2-7 is not carried out any more, at the moment, the rotating handle 2-10 and the rotating rod 2-9 are rotated, the first filter screen plate 2-8 and the rotating ring 2-7 are rotated by eighty degrees, and the gas is filled into the sealed and fixed air bag 2-14 through the air inlet pipe 2-15, the fixed ring 2-2 and the rotating ring 2-7 are fixed again by utilizing the sealed fixed air bag 2-14, at the moment, the coal dust is continuously filtered by the other side of the first filter screen 2-8, the utilization rate of the filter screen is also improved, at the moment, the coal dust adhered to one side of the first filter screen 2-8 can generate an acting force to one side of the negative pressure fan set 4 under the action of the negative pressure fan 4, part of the coal dust can fall off from the first filter screen 2-8 and fall into the second dust collecting hopper 2-11, and the coal dust is collected by utilizing the second dust collecting hopper 2-11;
when the rotation of the negative pressure fan 4 is stopped, the first filter screen plate 2-8 is free from external acting force, at the moment, the compressed first shaking spring 2-3 and the stretched second shaking spring 2-4 can drive the fixing ring 2-2 to shake in the fixed shaking seat 2-1, coal dust adhered to one side of the first filter screen plate 2-8 is shaken off, and due to the arrangement of the second filter screen plate 2-12, the phenomenon that the falling coal dust is discharged under the action of the negative pressure fan group 4, and a good filtering effect cannot be achieved is avoided;
the gas after filtration is purified by the activated carbon purification plate 3, and the purified gas is discharged by the water curtain dust-settling device 5 to improve the humidity of the gas, so that the dust-settling purification operation is completed.
