The working principle of the precipitation and dehydration integrated system for washed coal provided by the invention is as follows:
starting an external power supply, allowing the coal foam to be treated and water to enter the tank body 1 through the feed inlet 31, adding a proper amount of flocculant, filling the tank body 1 with solution, allowing the overflowed water to enter the water tower 36 through the overflow pipe 37, standing the coal foam in the tank body 1 for a long time, and allowing the ore particles to gather and settle under the action of the flocculant during passing, so as to form precipitates with recycling values, wherein the precipitates are continuously and uniformly settled in the storage bins 24. The step motor 42 is started first, and the step motor 42 rotates 45 degrees each time, then rotates 45 degrees again after standing for a certain time, and the cycle is continued. The stepping motor 42 drives the hydraulic pump 41 and the telescopic rod 43 to rotate 45 degrees, the rotary bin 34 and the hydraulic pump 41 rotate relatively, the telescopic rod 45 drives the cover plate 44 to rotate 45 degrees, the cover plate 44 rotates just above one of the storage bins 24, the cover plate 44 drives the inclined plane column 51 to rotate 45 degrees (the highest point of the bottom surface of the inclined plane column 51 is always under the cover plate 44), when the inclined plane column 51 rotates, eight push rods 27 whose bottom surfaces are connected with the guide rails 53 in a sliding manner slide up and down along with the rotation of the guide rails 53, the balls 28 at the top ends of the push rods 27 roll in the guide rails 53, when the cover plate 44 rotates just above one of the storage bins 24, the push rod 27 at the highest point of the bottom surface of the inclined plane column 51 just rises to the highest point, and the pressing plate 29b at the bottom end of the push rod is just at the top of the corresponding dewatering bin 25, the bottom end of the feeding channel 26 corresponding to the side wall of the dewatering bin 25 is just below the pressing plate 29b, and the bottom end of the material guiding pipe 54 at the bottom of the inclined plane column 51 is just communicated with the top end of the feeding channel 26; starting the hydraulic pump 41, the hydraulic pump 41 drives the telescopic rod 43 to descend, the telescopic rod 43 drives the cover plate 44 to descend, so that the bottom surface of the cover plate abuts against the top end of the storage bin 24 below, the storage bin 24 is sealed, and external sediments and water cannot enter the storage bin 24 any more; during the descending process of the cover plate 44, the bottom of one end of the cover plate 44 slides downwards in the first chute 52 inside the inclined plane column 51, and at the same time, the bottom surface of the cover plate 44 presses the first slide rod 61 at the corresponding position downwards, the first slide rod 61 slides downwards, presses the second spring 62, and at the same time, pushes the slide door 63 to slide downwards, so that the slide door 63 slides into the second chute 65, the slide door 63 no longer blocks the discharge opening 64, and the discharge opening 64 is communicated with the material guiding pipe 54, at this time, the sediment in the storage bin 24 enters the corresponding dewatering bin 25 through the discharge opening 64, the material guiding pipe 54 and the material feeding channel 26, and at the same time, a part of the water in the water tower 36 is discharged through the first water discharging pipe 38, and another part of the water enters the rotating bin 34 through the water pipe 35, and then flows through the water guiding pipe 33 and the elbow pipe 39 into the spraying pipe 39a in the cover plate 44, then the water is sprayed into the storage bin 24 through the spraying pipe 39a, so that on one hand, the sediment in the storage bin 24 is cleaned, the sediment can completely enter the corresponding dehydration bin 25, on the other hand, the sediment is favorably diluted to become fluid, and the speed of the sediment entering the dehydration bin 25 is accelerated; when the sediments in the storage bin 24 are completely discharged, the hydraulic pump 41 drives the telescopic rod 43 to ascend, the telescopic rod 43 drives the cover plate 44 to ascend, the sediments in the tank body 1 continuously enter the storage bin 24, during the ascending process of the cover plate 44, the bottom end of one end of the cover plate 44 slides upwards in the first chute 52 in the inclined plane column 51, meanwhile, the corresponding first slide bar 61 is not interfered by the cover plate 44 any more, and slides upwards under the pushing of the second spring 62, the first slide bar 61 drives the slide door 63 to slide out of the second chute 65, and the discharge port 64 is sealed; then starting the stepping motor 42 to rotate for 45 degrees continuously, driving the hydraulic pump 41 and the telescopic rod 43 to rotate for 45 degrees, the telescopic rod 43 driving the cover plate 44 and the inclined plane column 51 to rotate for 45 degrees, the cover plate 44 rotating to the right above the next adjacent storage bin 24, and the inclined plane column 51 rotating to make the push rod 27 at the highest point of the bottom surface start to slide downwards along the inclined plane for a certain distance, the ball 28 at the top end of the push rod 27 rolls in the guide rail 53, and the pressing plate 29b at the bottom end moves downwards together; thereafter, the cover 44 repeats the above-mentioned pushing-down action to discharge all the deposits in the storage bins 24 passing through to the dewatering bin 25, when the cover 44 passes through four storage bins 24, that is, when the cover 44 rotates 180 degrees, the lowest point of the bottom surface of the inclined plane column 51 is rotated to the highest point of the bottom surface of the inclined plane column 51 at the beginning, the push rod 27 at this point slides downward along with the rotation of the inclined plane column 51, and the pressing plate 29b also descends to the lowest point from the highest point in the dewatering bin 25, in this process, the push rod 27 drives the support rod 29 and the pressing plate 29b to move downward, the other end of the support rod 329 slides downward in the rope groove 83 in the column 23, the upper portion of the rope 82 is retracted into the rope bin 84, and the pressing plate 29b presses the deposits, and the reaction force of the deposits to the pressing plate 29b causes the first spring 29a to be compressed, the push rod 27 and the press plate 29b are buffered, the moisture in the sediment is pressed out, the moisture is filtered by the gauze 72 on the side wall of the dewatering bin 25 and then is discharged out of the column body section 22 through the support net 73 and the second water discharge pipe 71, and the support net 73 supports the gauze 72 in the process that the press plate 29b presses the sediment, so that the gauze is prevented from being damaged by the pressing force; when the push rod 27 reaches the lowest point, the sediment is compressed to the maximum extent, the moisture in the sediment is fully pressed out, meanwhile, the other end of the supporting rod 29 just presses the second sliding rod 86 to the lowest point, the third spring 87 is compressed in the process of sliding the second sliding rod 86 downwards, the tooth grooves 88 slide downwards to drive the gear 89 to rotate, the gear 89 drives the rack 89a to slide towards the inside of the column 23, finally, the rack 89a does not abut against the limiting block 85 any more, under the action of the gravity of the bottom door 81 and the sediment, the corresponding bottom door 81 rotates to open, the pull rope 82 slides downwards until the limiting block 85 is limited, the bottom door 81 stops rotating, and the sediment in the dewatering bin 25 slides out from the bottom end along the force of the bottom to leave the dewatering bin 25; when the cover 44 rotates for the next 180 degrees, the lowest point of the bottom surface of the inclined plane column 51 starts to rotate and is far away from the initial point, and the highest point of the bottom surface of the inclined plane column 51 starts to approach the initial point, in the process, the push rod 27 at the initial point slowly rises along the bottom surface of the inclined plane column 51, the push rod 27 drives the supporting rod 29 and the pressing plate 29b to rise, the pressing plate 29b loses the reaction force of the sediment, the first spring 29a resets, the other end of the supporting rod 29 no longer abuts against the second sliding rod 86, slides upwards under the action of the third spring 87 and drives the toothed slot 88 to slide upwards, the toothed slot 88 drives the gear 89 to rotate, the gear 89 drives the rack 89a to slide towards the rope slot 83, and finally the rack 89a resets, and the other end of the supporting rod 29 drives the pulling rope 82 to rise simultaneously, the pulling rope 82 slides in the rope groove 83 and the rope bin 84, and pulls the bottom door 81 to rotate, and the limiting block 85 rises along with the pulling rope 84; when the cover plate 44 rotates once again to reach the initial position directly above the storage bin 24, the highest point of the bottom surface of the inclined plane column 51 reaches the initial point, the push rod 27, the support rod 29 and the pressing plate 29b at this point just rise to the highest point, the pull rope 82 also rises to the highest point, the bottom door 81 just covers the bottom of the dewatering bin 25 corresponding to 1, and at this time, the top of the stopper 85 on the pull rope 84 abuts against the bottom surface of the rack 89a, so that the rack 89a rotates upward around the torsion spring 89b, the stopper 85 passes over the rack 89, the rack 89a returns to the horizontal position under the action of the torsion spring 89b and again abuts against the bottom surface of the stopper 85, and since the top surface of one end of the rack 89a abuts against the inside of the column 23, the rack 89a cannot rotate downward around the torsion spring 89b, so that the stopper 85 cannot pass over the rack 89a and the bottom door 81 does not open; with the rotation of the cover plate 44 and the inclined plane posts 51, the sediment in each storage bin 24 enters the dewatering bin 25 in the above sequence, and then the push rod 27 and the press plate 29 are pushed to slide up and down by the rotation of the inclined plane posts 51, so that the reset and the compression of the sediment are realized.
