Equipment and materials described main components The main components are: ⑴ ⑵ screw conveyor drum differential ⑶ ⑷ ⑸ main motor and auxiliary motors ⑹ base [1] use of advanced involute planetary gear differential, spiral and drum The difference between the speed of 2 ~ 30r / min, the differential regulation accuracy value ≤0.1rpm, screw torque ≥5000Nm, differential speed changes depending on the load of sludge and concentration, poor speed automatic feedback regulation, pusher power automatic compensation to ensure that the cake Constant dryness, to get a better cake. [2] drum using carbon steel, welded, processed to eliminate intergranular corrosion after treatment, enhanced corrosion performance, cone inlaid cylinder taphole replaceable wear-resistant, corrosion-resistant nano Jingang Yu (ceramic) casement. Drum wall surface mounted vertical direction by reducing logistics in order to protect the inner surface of the bars are not being worn. [3] unit and sludge, sewage contact parts made of carbon steel; running, the unit noise ≤85dB (A), vibration intensity ≤5mm / s. [4] chassis, engine hood are made of carbon steel, base made of high quality carbon structural steel, mica and iron oxide-containing bottom spray primer 80μmDFT, senior neoprene surface spray paint 100μm, all contact with the material PTFE gasket materials. [5] Decanter machine primary and secondary dual motor, using well-known brand of motors meeting IEC43-1 standard, 380V, three-phase, 50Hz, AC squirrel cage induction motor for horizontal motors, motor protection class according to IP44 standards, insulation grade is F. Decanter machine drum by an electric motor, inverter drive, start gentle, infinitely adjustable during operation. [6] The whole assembly is complete, empty computerized balancing instrument commissioning phase for the entire testing, and load balancing to do with water simulation experiments, to ensure the stability and reliability of the machine is running. [7] Decanter machine actually running power consumption is not the main and auxiliary motor rated power superposition, but should calculate the actual power consumption. Our machine under normal operating conditions Decanter actual power consumption P =? U? I? COSφ, COSφ = 0.88. Automatic differential system [8] Decanter machine facilities, is an advanced form of international differential with when the feed sludge concentration or load changes, slip automatic feedback regulation, pusher power automatic compensation to maintain solid discharge Hang dry slag, reduce Decanter machine blocking material failure, compared with hydraulic differential is not only fast, but also low power consumption. [9] Decanter machine bearings are lubricated with grease mandatory life more than 100,000 hours. [10] without the need to disassemble the fault blocking material, as long as the device automatically starts slagging auger, clear product material. [11] The drum separation liquid discharge port, the liquid layer thickness using an adjustable weir. [12] Decanter machine with an emergency stop, the motor overheating / overload, overload auger, bearing temperature, vibration protection. [13] The centrifuge temporarily shut down two to three days without, no backwash, requires more than a week shutdown in order to prevent the machine dry plates form a block of residual materials required backwash before shutdown. [14] used to connect all use carbon steel fasteners, bolts and nuts in line with ISO272, ISO4759 / 1 8.8 grade requirements, gaskets conform ISO / R887 requirements connected with the base fasteners are made of galvanized steel and painted to protect.
