Main specifications and technical parameters Technical parameters Model DYQ750P1 DYQ1000P1 DYQ1500P1 DYQ2000P1 DYQ2500P1 DYQ3000P1 power master 5.5 7.5 7.5 2.2 34 sets of 111,317,192,225 filter width (mm) 750 1000 1500 2000 2500 3000 capacity (m3 / hr) 3-7 6-118-1612-23 16-2819-33 Dimensions Length (mm) 5200 5400 5500 5600 5600 5650 Width (mm) 1650 1900 2380 2900 3400 3900 height (mm) 1950 2100 2150 2200 2300 Total Weight 2350 3200 4,200,650,075,009,000 10000 each part of the technical characteristics: 1, the transmission gear from the shaft, seat sealed bearings and cycloid machine components, the outer shaft bread quality natural rubber to increase transmission friction coefficient, using inverter to control the motor speed, to ensure the filter with smooth speed control. 2, the liquid mixing apparatus of the machine uses non-blocking static mixer (not easy to use flocculation material stirred dynamic mixer) for mixing the sludge and chemical liquid, sludge before it is installed in the chute, you can After flocculant sludge from the surrounding high-pressure injection pipe into the mixing reactor, can polyelectrolyte solution and diluted sludge particles collide quickly contacted by regulating the flow of liquid sludge to achieve optimum flocculation and dewatering . 3, feed distribution means sludge after flocculation mixer into the feed distribution means, by the diversion and the overflow plate, flat plate, side baffle materials are distributed in the gravity concentration section, in order to improve the sludge gravity dehydrating effect, above the gravity dewatering zone set up multiple hydraulic conductivity finger, the upper part of the sludge accumulation of free water seeping import filter. 4, the role of the tensioning device is a tensioning device tensioning, lower filter belt, all driven by the main drive roller stick operation, and certain of extrusion pressure and shear force is applied to the dehydration of the cake, the machine used Buffered cylinder tension by adjusting the air pressure to control the size tension. 5, the frame of the rack uses high-GB solid square tubes welded whole surface by sand-blasting grade sa2.5 level, and then re-embalmed or fluorocarbon thermal spray zinc treatment, the corrosion resistance can be more than 10 years. 6, gravity dehydration unit gravity dehydrator main role is to take off the material of free water, interstitial water, reduce the flow of materials to prepare for the next filter press, the structure is designed to be divided into separate gravity filter dehydration (ie thickener), plus the upper and lower layers of the laminated filter gravity dehydration, after 6-11 meter long gravity dehydration, sludge in the large number of free water is sufficiently filtered, then sludge squeeze to withstand greater pressure. 7, pre-press dewatering perforated roll preloading dewatering holes perforated roller is evenly distributed by the roll surface composition, filtered water can be discharged outside the maximum dewatering roll, squeeze after the initial formation of sludge cake. 8, high-pressure high-pressure dewatering roll dewatering roll is made up of several different diameter roller composition, roll, coated high quality natural rubber or PE, was standing with two S-shaped filter sequentially wound between the rollers, roller diameter from large decreases, a certain pressure increase, the material pressure increases suffered by the small, crowded under pressure and shear force, initially formed a relatively dry cake. 9, squeeze rollers are aligned through a high pressure cake if still not ideal, the need for a strong pair of nip rolls squeeze the maximum extent of the sludge solid-liquid separation. Each group is a pair of nip rolls fixed, and the other activities for the balloon pressure rollers, low activity appearance bread roll hardness quality natural rubber to squeeze soft contact with the sludge, adjust the appropriate pressure to ensure that the sludge by and fully dehydrated. 10, correction means automatic correction system uses cylinder, solenoid valves, switches and other components access device for automatic tracking correction, the system is sensitive, reliable, and long life, stable position for the belts, the general deviation error is less than 15mm. 11, pneumatics pneumatic belt tensioning device to control the filter, correction and adjustment of the pressure of the nip rolls, operated, pneumatic control components is sensitive, reliable and durable. 12, filter press filter made by weaving polyester filament, divided into endless side interface and the interface, based on characteristics of the sludge was different selection of different filters, the machine uses high strength, good permeability, easy to plug, smooth surface solid high recovery rate, easy to clean, easy to assemble high-quality filter. 13, cleaning device cleaning device consists of water connecting pipe and nozzle, stencilled, valves, waterproof covers, filter composed of 304 stainless steel nozzles, each nozzle can be individually cleaned and replaced. Swing band pass filter, fan-shaped spray of water will effectively be continuously attached to the residual sludge to remove the filter belt. 14, the role of discharge means discharging the filter blade is scraped filter cake, blade pressure is adjustable and ensure less wear and tear on the filter. 15, bearing and housing in order to prevent corrosion, all bearing and housing double V-ring seals, bearing made of ductile iron, the machine uses double row spherical roller bearing, load bearing capacity, long service life. 16, filtrate collection device to prevent leakage or wash water and filtrate splash out, all through the rinse and filtrate water tray to collect, concentrate discharge or emission respectively. 17, to protect both sides of the apparatus of the machine is set up safety net and warning signs, electric limit switch cable fault emergency response system to monitor the composition of the adjustment process in the filter with all the action, adjust the system when the cause deviation in process Over time, the limit switch is triggered and stops. 18, concentrated sludge dewatering entire cabinet power distribution system consists of a control cabinet (manual contact control or PLC controller) unified operational control, control cabinet for the host and its ancillary equipment - sludge pump, cleaning pumps, mixers, liquid pumps, air compressors, conveyors and other equipment to provide power, start, stop and short motor overheating, overload, lack of control and protection and alarm phase.
