At this time, the first motor 111 is started to rotate forward, so that the two groups of adjustment blocks 121 move to the right on the two groups of third threaded rods 115, so that The two sets of clamping frames 127 clamp the extension ends of the sliding seats on both sides of the filter cloth 6 and drive them to move to the right. During the process of moving to the right, the two sets of extension rods repeatedly move up and down on the inner walls of the two sets of corrugated plates 128, thereby The two groups of sliding blocks 125 stretch upwards the two groups of springs 126, and the two groups of springs 126 are stretched and rebounded, thereby driving the single group of filter cloth 6 to bump and shake up and down when the two groups of clamping frames 127 are turned to the right, and the filter cloth 6 Shake off the formed slime cake;

Step 2: Then start the first hydraulic cylinder 812 to extend, so that the mounting plate 813 moves downward to a certain position, and is clamped by two sets of clamping mechanisms through the sliding seats on both sides of the single set of filter cloth 6, and then Start the first hydraulic cylinder 812 to shrink, and lift the single set of filter cloth 6. At this time, start the water pump 824 to extract the cleaning liquid through the water guide pipe, and then transport the cleaning liquid to the two sets of water spray chambers 822 through two sets of retractable water pipes Clean the single set of filter cloth 6. During the cleaning process, start the second motor 817 to rotate forward and reverse, so that the output end of the second motor 817 drives the fourth threaded rod 818 forward and reverse through the second transmission belt 820. At this time, the two groups The moving block 821 moves in the middle or both sides of the outer surface of the output end of the second motor 817 and the fourth threaded rod 818 respectively. Sliding upward to both sides, so that the water spray chamber 822 moves upward, when the two groups of moving blocks 821 move to the middle, the lower two groups of hinged blocks slide to the middle on the fixed shaft, so that the water spray chamber 822 moves downward, realizing two The up and down reciprocating movement of the water spray chamber 822 improves the effect of cleaning the filter cloth 6;

Step 3: When the cleaning mechanism cleans a single set of filter cloth 6, start the first electric telescopic rod 117 to shrink, so that the second driven wheel 119 slides downward, and the driving wheel 113 will not drive multiple sets of first driven wheels 116 transmission, then start the first motor 111 to rotate forward, so that the mobile frame 911 moves to the right on the first threaded rod 112, and when moving to the below of the two groups of clamping mechanisms, the first motor 111 is closed, and the cleaning mechanism 8 When cleaning the slime impurities on a single set of filter cloth 6, the sewage is transported into the circular tank through the chute on both sides of the circular tank, then transported into the recovery hose 9 through the shaftless auger 913, and then through the recovery hose 9 After being transported into the filter cloth 6 again, a secondary pressure filtration is carried out, which improves the utilization rate of the coal slime water.
