Operation principle of the present invention is as follows:
The pressure at the corresponding described water inlet pipe of thrust left 2 places that described piston 21 is subject to, and the pressure of the corresponding described lower box of the thrust to the right that piston 21 is subject to 5 bottoms, the namely pressure of described secondary filter screen 6 net rear sides.When the work of this device, impurity can be at the mesh of clogging secondary filter screen 6, thereby before making the net of secondary filter screen 6 and have pressure differential between net rear side.It should be noted that, the thrust left that above-mentioned piston 21 is subject to is greater than its suffered promotion to the right forever.
The pressure differential that the present invention has utilized secondary filter screen 6 to net front and net rear side just dexterously, in the time that pressure differential arrives 0.1MPa, act on that the thrust of piston 21 left and right ends is poor will reach 70 newton of setting, thereby make piston 21 overcome self friction resistance under the poor effect of thrust and hydraulic pressure tension force will be moved to the left, and then the lower end that promotes described lever 16 moves to left, thereby drive upper end and the movable valve plug 11 of lever 16 to move to right, the port of export of described blowdown bend pipe 7 is opened the most at last, and then the impurity before secondary filter screen 6 nets is discharged to outside lower box 5 by blowdown bend pipe 7 and described the second blow-off pipe 8.
Along with constantly carrying out of blowdown, before secondary filter screen 6 nets, dwindle gradually with the pressure differential of net rear side, originally bonded to the impurity meeting Automatic-falling on secondary filter screen 6, and be discharged to voluntarily outside lower box 5, finally making secondary filter screen 6 nets pressure differential front and net rear side become is zero, now movable valve plug 11 reset that moves to left under the effect of return spring 12, the port of export of above-mentioned blowdown bend pipe 7 is blocked the most at last, thereby completes automatic pollutant removal process one time.Along with the passing of running time, the port of export of described blowdown bend pipe 7 will be repeatedly, be automatically opened or block, thereby realize automatic pollutant removal, and the clean water finally obtaining can offer atomizing pump, spraying system etc., to ensure the normal operation of these equipment, and wholely remove contamination, purification process carries out automatically, do not need manually to intervene, more without any need for power drives, so just can ensure this device self security of operation under coal mine.
The foregoing is only preferred embodiment of the present invention, not taking the present invention as restriction, all any amendments of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
