The specific embodiment
As shown in Figure 2, centre bearing 7 is made up of hold-down support 13, seat ring 19, pivoting support 20, swivel mount 16 and travelling carriage 14;
Hold-down support 13 is a column, plays the effect of carrying thickener; Seat ring 19 is installed on the hold-down support 13, and is connected with the inner ring of pivoting support 20;
Swivel mount 16 is connected with the outer ring of pivoting support 20, and periphery on plane evenly distributes and 4 feather keys 21 and 4 are housed carry rake oil cylinder 18 on it, and the cross section of the cross section of feather key 21 and chute 22 is suitable, and 4 feather keys 21 are fixed on the side of swivel mount 16 peripheries; The periphery of travelling carriage 14 evenly is distributed with 4 chutes 22, and chute is a up/down perforation, and its position is corresponding with the feather key 21 on the swivel mount 16; Insert respectively in 4 chutes 22 on the travelling carriage 14 lower end of feather key 21, and travelling carriage 14 can slide along feather key 21 easy on and off; Fixedly connected with travelling carriage 14 in the lower end of carrying the piston rod 15 of rake oil cylinder 18.Piston rod 15 is 800mm with the effective length (stroke) of feather key 21.
As shown in Figure 1, centre bearing 7 is installed on the center stand column 2 of concentration basin 11 central authorities by holder 13;
Rotating cage 3 adopts rectangular-shaped truss structure, in light weight, good looking appearance, and good rigidly, the torsional strength height, it is big to bear torque, and secondary rake 1 is equipped with in its underpart, and fixedly connected with travelling carriage 14 in top;
Operation principle: provide high-pressure and hydraulic oil to drive hydraulic motor by hydraulic system, make transmission device 12 make circular motion, drive gear frame 9, swivel mount 16 rotations along plane on the pool wall of concentration basin 11; Swivel mount 16 drives travelling carriage 14 by 4 feather keys 21 and rotates thereupon, and the rotating cage 3 drive rake framves 5, distribution device 6, the secondary rake 1 that are fixed under the travelling carriage 14 rotate in concentration basin; In rake frame 5 rotating process, the rake teeth 4 that is installed in rake frame bottom is scraped the material that precipitates in the concentration basin in the awl hole that collects the concentration basin center, by the slag stock pump material is extracted out.The pair rake 1 that is installed in rotating cage 3 bottoms prevents that also along with rotating cage 3 rotations the underflow materials of boring in the hole is fixed, and it is unimpeded to guarantee that underflow materials effluxes.
When the material that is deposited to concentration basin 11 bottoms increases, when bed thickens, the working resistance of rake frame 5 also strengthens thereupon, when working resistance is increased to setting value, hydraulic system is cut off the oil circuit of hydraulic motor, and this moment, transmission device 12 stopped operating, and carries rake oil cylinder 18 and starts working, piston rod 15 drives travelling carriage 14 and upwards promotes, and rotating cage 3, rake frame 5 and rake teeth 4, secondary rake 1 integral body promote thereupon; Recover fuel feeding through the time-delay rear hydraulic motor, transmission device 12 begins rotation work again.After rake frame 5 promoted, working resistance reduced thereupon, if be reduced to setting value when following, carrying rake oil cylinder 18 quits work, rake frame 5 rests on rotary work on this height, and rake teeth 4 scrapes material to concentration basin central authorities, simultaneously, relied on gravity to descend gradually by the whole rake frame that promotes 5, until falling lowest part, when increasing to setting value once more along with working resistance, rake frame 5 is raised once more, repeat above action, thereby reach automatic rake-lifting, fall the purpose of rake.
When the working resistance of rake frame 5 constantly increases, when the piston rod 15 of carrying rake oil cylinder 18 rose near limit travel, the travel switch action was cut off the electricity supply, and complete machine is out of service.At this moment, after should fixing a breakdown, manually recover start again.
Electric-control system is furnished with frequency converter, by PLC control, can participate in the collection control of full factory, establishes automatic, manual dual mode, can regulate the oil drain quantity of hydraulic system oil pump in real time according to different material and working resistance situation.
Hydraulic system for transmission device 12, carry rake oil cylinder 18 power be provided, the oil pump of hydraulic system is a variable pump, changes the rotating speed of rake frame 5 according to the size of oil pump oil drain quantity, to reach the optimised process requirement.
