Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, this sludge drying mechanism comprises and is arranged on above dry heat dish 3, and what be connected with mud transfer roller 1 crowdedly rubs roller 10;
The external rings of described dry heat dish 3 is around being provided with chain 8;
The two ends of described chain 8 are driven by drive sprocket 5;
Between the top of described dry heat dish 3 and described chain 8, gear bar 9 is set;
On described chain 8, uniform being provided with harrows cutter 4;
The axle center place of described rake cutter 4 is provided with and described gear bar 9 intermeshing rake cutter driving gear 41.
The working process of this sludge drying mechanism is as follows:
As shown in Figure 1, mud is delivered to squeeze by mud transfer roller 1 rubs roller 10 place, squeeze rub roller 10 by mud squeeze be kneaded into noodles shape after drop down onto dry heat dish 3, it is uniform that the mud squeezed after rubbing falls into dry heat dish 3 into strips, dry heat dish 3 external rings is around installation chain 8, chain 8 is driven by the drive sprocket 5 at two ends, between the top of dry heat dish 3 and chain 8, gear bar 9 is set, on chain 8, uniform being provided with harrows cutter 4, as shown in Figure 2, the axle center place of rake cutter 4 is provided with and described gear bar 9 intermeshing rake cutter driving gear 41, the rotation acting on and drive and harrow cutter 4 is engaged each other by rake cutter driving gear 41 and gear bar 9, rake cutter 4 transmits through chain 8 and carries out cutting rapidly turning over throwing to the mud fallen on dry heat dish 3 simultaneously, it is vertical with mud that throwing direction is turned in cutting, drive through chain 8 after rake cutter 4 cuts and rotate around dry heat dish 3, next rake cutter 4 circulates and turns over throwing to mud, mud is vertically moved, rake cutter 4 is rotated around dry heat dish 3 by the driving of chain 8, the rake cutter 4 be in above dry heat dish 3 is connected with a joggle by rake cutter driving gear 41 and gear bar 9 and realizes harrowing the rotation of cutter 4, turning over after throwing terminates, rake cutter 4 when being in below dry heat dish 3 departs from gear bar 9, automatic stall, thus achieve and do not cut motionless effect, energy efficient.
Further, described dry heat dish 3 inside is provided with the heating system by thermal oil or steam heating.Realize the dry heat effect to mud.
Further, the side of described dry heat dish 3 is provided with air inlet heat recovery system 2.Carry out preheating by air inlet heat recovery system 2 recovery waste heat to air intake, inlet temperature is promoted to about 50 degree.Reduce plant energy consumption, reach the effect of energy-saving and emission-reduction.
Further, the top of described dry heat dish 3 arranges exhaust system 7, and described exhaust system 7 is tiny structure exhaust system.Mud is after turning over and throwing evaporation, and expellant gas is discharged by tiny structure exhaust system 7, and enter dedusting, deodoration system subsequent disposal, mud is through repeatedly turning over throwing, and finished product directly delivers from godown.
Further, described exhaust system 7 is provided with waste heat of condensation recovery system 6.Carry out recycling by the waste heat of the water vapour evaporation of discharging after the 6 pairs of drying sludge heating of waste heat of condensation recovery system, the heat of recovery is used for carrying out preheating to mud, thus reduces the energy consumption of device on the whole, reaches the effect of energy-saving and emission-reduction.
Further, one end of described mud transfer roller 1 is provided with scraper 11.Can effectively prevent mud adhesion on the conveyor belt, improve device to drying sludge efficiency.
