A method for using a power grid engineering waste mud dewatering system capable of generating block-shaped mud cakes.

During the waste mud treatment process, it is necessary to process the waste mud into block-shaped mud cakes. The specific process is as follows: first, the waste mud generated by the power grid engineering is added into a box;

S1: Water removal process: control the hydraulic cylinder to work, start the telescopic end of the hydraulic cylinder to extend and drive the pressing plate to move downward synchronously. When the pressing plate moves downward, multiple groups of through holes on the surface are separated from multiple groups of plug rods. The pressing plate squeezes the waste mud inside the box body, so that the water in the waste mud enters the other side of the pressing plate through the multiple groups of through holes on the surface of the pressing plate. Control the water pump to work so that the water pump extracts the squeezed water and transports it to the designated position through the pipeline. When the water is squeezed out, a certain amount of mud will be brought out. Start the telescopic end of the hydraulic cylinder to shorten and drive the pressing plate back to its original position, so that the multiple groups of plug rods are inserted into the through holes on the surface of the pressing plate again, and the squeezed mud is pushed back into the box body. Control the heating wires inside the multiple groups of heating plates to be energized so that the heat of the heating wires inside the multiple groups of heating plates is transferred to the surface of the dehydrated waste mud to dry it;

S2: Extrusion and cutting process: when the waste mud is dried to form blocks, the heating is stopped, the first motor is controlled to work, the output shaft of the first motor is started to rotate and drive the first threaded rod to rotate, so that the first threaded rod drives the first threaded block to move, so that the first threaded block drives the sliding rod to move synchronously, so that the sliding rod drives the sleeve to move synchronously, so that the sleeve drives the transmission plate to move in the direction away from the box, so that the transmission plate drives the baffle to move synchronously, and the baffle drives the trapezoidal block to slide on the surface of the beam, so that the multiple groups of frustum-shaped blocks on the surface of the baffle slide in the conical through holes at the lower end of the box, so that the baffle is no longer tightly against the lower end of the box, and when the baffle moves to leave the bottom of the box, the first motor is stopped, and the telescopic end of the hydraulic cylinder is started to extend again to push the waste mud, so that the waste mud passes through the lower end of the box. The tapered through hole is extruded, the external power supply of the second motor is controlled, the output shaft of the second motor is started to rotate to drive the second threaded rod on one side to rotate, the second threaded rod rotates to drive the toothed belt pulley on one side to rotate, so that the toothed belt pulley drives the toothed belt pulley on the other side to rotate synchronously through the toothed belt, so that the toothed belt pulleys on both sides drive the second threaded rods on both sides to rotate synchronously, so that the second threaded rods on both sides drive the second threaded blocks on both sides to move synchronously, so that the second threaded blocks on both sides drive the cutter to move synchronously, so that the cutter cuts the extruded mud strips into blocks and drops them onto the surface of the conveyor belt, the output shaft of the second motor is continuously controlled to rotate forward and reversely, so that the cutter reciprocates, so that the extruded mud strips are cut into blocks, and the conveyor belt is controlled to rotate to transport the cut waste mud.

S3: Cleaning process: When the cutting is completed, the above-mentioned mechanism is restored to its original position, and clean water is added to the inside of the box so that the clean water can clean the sludge remaining inside the box, and the cylinder is controlled to work, and the telescopic end of the cylinder is started to shorten to drive the circular plate to move synchronously, and the circular plate drives the rack to move synchronously, and the rack drives the gear to rotate, so that the gear drives the shaft to rotate, and the shaft drives the upper end of the box to tilt forward, so that the water inside the box flows, and the water inside the box flows out through the tapered through hole at the lower end.

The invention proposes a waste mud dewatering system for power grid projects capable of generating block-shaped mud cakes, and has the beneficial effects that: through the cooperation of the block cutting device, the box body and the conveyor belt, the output shaft of the first motor rotates to drive the first threaded rod to rotate, so that the transmission plate can drive the baffle plate to move synchronously, and the baffle plate can drive the trapezoidal block to slide on the surface of the crossbeam, so that the multiple groups of truncated cone-shaped blocks on the surface of the baffle plate slide in the conical through holes at the lower end of the box body, so that the baffle plate is no longer tightly pressed against the lower end of the box body, and when the baffle plate moves to leave the bottom of the box body, the first motor is stopped, and the telescopic end of the hydraulic cylinder is started to extend again to push the waste mud, so that the waste mud can pass through the box body. The tapered through hole at the lower end is extruded, and the output shaft of the second motor rotates to drive the second threaded rod on one side to rotate, so that the cutter can cut the extruded mud strips into blocks and drop them onto the surface of the conveyor belt. The output shaft of the second motor is continuously controlled to rotate forward and reversely, so that the cutter can reciprocate, so that the extruded mud strips can be cut into blocks, and the conveyor belt is controlled to rotate to transport the cut waste mud. The waste mud can be continuously cut into blocks. After the waste mud is dehydrated and dried, it can be extruded into strips and then cut into blocks by the cutter, which can effectively improve the work efficiency of dehydrating the waste mud into blocks.

Working principle:

During the construction of the power grid project, waste mud is bound to be generated. During the treatment of the waste mud, it is usually necessary to process it into block-shaped mud cakes. The specific process is as follows: first, the waste mud generated by the power grid project is added into the box 1.

S1: Water removal process: Control the hydraulic cylinder 6 to work, start the telescopic end of the hydraulic cylinder 6 to extend and drive the pressing plate 14 to move downward synchronously. When the pressing plate 14 moves downward, the multiple groups of through holes on the surface are separated from the multiple groups of insertion rods 5. The pressing plate 14 squeezes the waste mud inside the box 1, so that the water in the waste mud enters the other side of the pressing plate 14 through the multiple groups of through holes on the surface of the pressing plate 14. Control the water pump 15 to work so that the water pump 15 extracts the squeezed water and transports it to the designated position through the pipeline. When the water is squeezed out, a certain amount of mud will be brought out. Start the telescopic end of the hydraulic cylinder 6 to shorten and drive the pressing plate 14 back to its original position, so that the multiple groups of insertion rods 5 are inserted into the through holes on the surface of the pressing plate 14 again, and the squeezed mud is pushed back into the box 1. Control the heating wires inside the multiple groups of heating plates 10 to be energized so that the heat of the heating wires inside the multiple groups of heating plates 10 is transferred to the surface of the dehydrated waste mud to dry it.

S2: Extrusion and cutting process: When the waste mud is dried to form blocks, the heating is stopped, the first motor 801 is controlled to work, and the output shaft of the first motor 801 is started to rotate to drive the first threaded rod 803 to rotate, so that the first threaded rod 803 drives the first threaded block 809 to move, and the first threaded block 809 drives the slide bar 808 to move synchronously, so that the slide bar 808 drives the sleeve 807 to move synchronously, so that the sleeve 807 drives the transmission plate 806 to move away from the box body 1, so that the transmission plate 806 drives the baffle 804 to move synchronously, and the baffle 804 drives the trapezoidal block 805 to slide on the surface of the beam 12, so that the multiple groups of truncated cone blocks on the surface of the baffle 804 slide in the conical through hole at the lower end of the box body 1, so that the baffle 804 is no longer tightly against the lower end of the box body 1.

When the baffle 804 moves to leave the bottom of the box body 1, the first motor 801 is stopped, the telescopic end of the hydraulic cylinder 6 is started to extend again to push the waste mud, so that the waste mud is extruded through the tapered through hole at the lower end of the box body 1, and the external power supply of the second motor 902 is controlled, and the output shaft of the second motor 902 is started to rotate to drive the second threaded rod 903 on one side to rotate, and the second threaded rod 903 rotates to drive the toothed belt pulley 901 on one side to rotate, so that the toothed belt pulley 901 drives the toothed belt pulley 901 on the other side to rotate synchronously through the toothed belt 905, so that The toothed pulleys 901 on both sides drive the second threaded rods 903 on both sides to rotate synchronously, so that the second threaded rods 903 on both sides drive the second threaded blocks 911 on both sides to move synchronously, and the second threaded blocks 911 on both sides drive the cutter 910 to move synchronously, so that the cutter 910 cuts the extruded mud strips into blocks and drops them onto the surface of the conveyor belt 3, and the output shaft of the second motor 902 is continuously controlled to rotate forward and reversely, so that the cutter 910 reciprocates, so that the extruded mud strips are cut into blocks, and the conveyor belt 3 is controlled to rotate to transport the cut waste mud.

S3: Cleaning process: When the cutting is completed, the above-mentioned mechanism is restored to its original position, and clean water is added to the inside of the box body 1 so that the clean water can clean the sludge remaining inside the box body 1, and the cylinder 201 is controlled to work, and the telescopic end of the cylinder 201 is started to shorten to drive the circular plate 202 to move synchronously, and the circular plate 202 drives the rack 207 to move synchronously, and the rack 207 drives the gear 205 to rotate, so that the gear 205 drives the rotating shaft 13 to rotate, and the rotating shaft 13 drives the upper end of the box body 1 to tilt forward, so that the water inside the box body 1 flows, and the water inside the box body 1 flows out through the tapered through hole at the lower end.

S4: Technical advantages: Through the cooperation of the cutting device 9, the box 1 and the conveyor belt 3, the output shaft of the first motor 801 rotates to drive the first threaded rod 803 to rotate, so that the transmission plate 806 can drive the baffle 804 to move synchronously, and the baffle 804 can drive the trapezoidal block 805 to slide on the surface of the beam 12, so that the multiple groups of truncated cone blocks on the surface of the baffle 804 slide in the conical through hole at the lower end of the box 1, so that the baffle 804 is no longer tightly pressed against the lower end of the box 1, and when the baffle 804 moves to leave the bottom of the box 1, the first motor 801 is stopped, and the telescopic end of the hydraulic cylinder 6 is started to extend again to push the waste mud, so that the waste mud can pass through the conical through hole at the lower end of the box 1.
