Main specifications and technical parameters of technical parameters model DYQ750P1 DYQ1000P1 DYQ1500P1 DYQ2000P1 DYQ2500P1 DYQ3000P1 power host 5.5 7.5 7.5 2.2 34 sets of 111,317,192,225 filter width (mm) 750 1000 1500 2000 2500 3000 processing 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 10000 4,200,650,075,009,000 various parts of the technical characteristics: 1, transmission gear from the shaft, bearings and seal seat belt cycloid machine components, drive shafts appearance of bread quality natural rubber to increase transmission friction coefficient, using the inverter to control the motor speed to ensure the filter with smooth speed control. 2, liquid mixing device of this machine uses a non-blocking type static mixer (not easily stirred flocculation materials using dynamic mixer) for mixing the sludge and chemical liquid, which is installed in the chute before the sludge can be 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 and to achieve the best flocculation and dewatering . 3, feed distribution means sludge after flocculation mixer into the feed distribution means, by diversion and the overflow plate, flat plate, side baffle materials are distributed in the gravity concentrate segment, in order to improve the sludge gravity dehydration effect of gravity above the water dewatering zone setting a plurality of guide fingers, the upper part of the sludge accumulation of free water seeping import filter. 4. The role of the tensioning device tensioning device is on tension and lower filter belt, driving all the sticks running through the main drive roller, make sure extrusion pressure and shear force is applied to the dehydration of the cake, the machine tensioning cylinder buffered by adjusting the air pressure to control the size of the tension. 5, the rack of the chassis using high quality GB square tube welded overall firm, level surface by sand-blasting sa2.5 grade, and then re-embalmed or fluorocarbon thermal spray zinc processing, its corrosion resistance can be more than 10 years. 6, gravity dewatering unit gravity dewatering device main role is to take off the material free water, interstitial water, reduce the flow of materials to prepare for the next filter press, and its structure is designed to filter into separate gravity dehydration (i.e., thickener), together with the upper and lower laminated layers of a gravitational dewatering screen, after 6-11 meters long gravitational dewatering, the sludge is sufficiently large quantity of free water was filtered off, then sludge squeeze to withstand greater pressure. 7, preload preload dehydration dehydration perforated roller rolls are perforated holes evenly distributed from the roll surface consisting of water filtration 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, roller coated with high quality natural rubber or PE, two S-shaped vertical filter belt was wrapped around the turn between the roller, the roller diameter by large decreases, a certain pressure increase, so that the material stress suffered by small increases in extrusion pressure and shear force, the initial formation of relatively dry cake. 9. Align squeeze through the high-pressure roll cake if it is 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, the other activities for the balloon pressure roller, lower activity bread rolls appearance of high-quality natural rubber hardness to squeeze with soft contact sludge, adjust the appropriate pressure to ensure the sludge by and fully dehydrated. 10, corrective devices automatic correction system uses cylinder, solenoid valves, proximity switches and other components of the device for automatic tracking correction, the system is sensitive, reliable, and long life, with the stable position of the filter, the general deviation error does not exceed 15mm. 11, pneumatics pneumatic belt tensioning device for controlling the filter, correcting and adjusting pressure nip rolls, operated, pneumatic control components is sensitive, reliable and durable. 12, filter press filter woven from polyester yarn made, divided end interface and interfaces for no reason, based on physical characteristics of different sludge use different filters, this machine uses high strength, good permeability, clogging, smooth surface solid high recovery rate, easy to clean, easy to assemble high-quality filter. 13, cleaning device cleaning device by connecting water pipes and nozzles, stencilled, valves, waterproof cover, filter composed of 304 stainless steel nozzles, each nozzle can be individually cleaning and replacement. Swing band pass filter, fan-shaped spray of water will effectively continuously attached to the belt filter to remove residual sludge. 14, the filter effect of discharge means discharging the blade is scraped filter cake, blade pressure is adjustable, and to ensure that the smaller the wear of 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 adopts double row spherical roller bearings, load bearing capacity, long service life. 16, filtrate collection device to prevent leakage or wash water and filtrate splash out all the washing and filtrate were collected through the water tray, respectively discharge or centralized emissions. 17, protective devices on both sides of the machine is set up safety nets and warning signs, electric wire limit switch failure emergency response system to monitor the composition of the filter with the adjustment process of all the action, when the adjustment system in causing deviation in process Over time, the limit switch is triggered and stops. 18, the entire cabinet concentrated sludge dewatering system consists of a set of power distribution control cabinet (manual contact control or PLC controller) unified operational 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.
