Description
Technical field
The present invention relates to the sludge dehydration device in a kind of waste water, the sewage treatment process, and the squeeze dehydration unit used of solid-liquid separation, particularly a kind of continuous double-roller opposite-compacting type water extracter.
Background technology
The mud that water treatment system produces, water ratio is very high, and volume is very big, carries, handles or dispose all inconvenient, mud concentrates the volume that can dwindle mud, and through the mud after concentrating, its water ratio is still more than 94%, be mobile shape, volume is big, therefore also needs to carry out sludge dewatering.Belt filter press is the dehydration equipment of continuous operation, at present, belt filter press mostly is S type or W type, S type and W type squeezing mode are to utilize the tension force of filter cloth that mud is exerted pressure, because these two kinds of pattern rollers are not to pressing, so squeeze is minimum, so be difficult to solve the high difficult problem of moisture content of the cake, and exist pressure little, the defective that the squeezing time is long, productivity is low, because these modes are to utilize the tension force of filter cloth to carry out press filtration, thus very high to the tensioning requirement of filter cloth, also influential to the life-span of filter cloth.And two rollers to the pressure mode dewater exist can't draining problem, the moisture percentage in sewage sludge that causes treated mistake is still greater than 90%, emphasis of the present invention has solved these technical barriers.
Summary of the invention
The invention provides continuous double-roller opposite-compacting type water extracter, what it adopted is the roll extrusion of roll-to-roll rotation relay-type, it is big to have squeeze force, the advantage that the squeezing time is short, reduce tensile force requirement simultaneously to filter cloth, guarantee the life-span of filter cloth and the solid content of mud cake, and successfully solved two rollers to press-dehydrating can't draining technical barrier.
The present invention has adopted following technical scheme: a kind of continuous double-roller is to pressing dehydrator, it is mainly by frame, power set, transmission mechanism, filter cloth, tightening device, flushing arrangement, feeding unit, dumping device is formed, it also comprises the upper roller parts, following roller part, transmission mechanism is provided with input shaft and some output shafts to being arranged above and below, input shaft connects with power set by shaft coupling I, last row's output shaft connects with the upper roller parts by universal coupling, under arrange output shaft and connect with following roller part by shaft coupling II, upper roller parts and following roller part are the roll extrusion of roll-to-roll rotation relay-type.
Following roller part is hollow roller, the surface is provided with some through holes, and the hollow roll subcenter is provided with the V-arrangement water container, and water container and frame are fixedly connected, following roller part solderless wrapped connection water device rotation and top roll extrude water and then flow into the water container discharge by through hole pressing during to pressure.Described roller part one end down is connected with transmission mechanism, the inner chamber of following roller part connects the open tube of an end shutoff by bearing, the open tube conduct bolster of roller part down is fixed on the frame, and described open tube is provided with water container and is communicated with as water shoot with it.
Slide block is equipped with at the two ends of upper roller parts, frame is provided with guide rail, slide block is arranged in guide rail and can slides along guide rail, slide block is connected with self-operated regulator one end, the other end of self-operated regulator is connected with frame, self-operated regulator length is regulated automatically according to the position of slide block, and provides certain pressure by the slide block roller part that makes progress.
Transmission mechanism can be geartransmission, also can be chain sprocket drive; Self-operated regulator is the subassembly of spring shock absorber, air energy storage vibroshock or spring and air energy storage.The roll body of following roller part is that annular filter screen is sleeved on the open tube and forms.
The present invention has following technique effect: upper roller adopts the roll extrusion of roll-to-roll rotation relay-type with following roller, utilizes roll gap pressure to dewater, because the contact area is little between roller, makes that squeezing is more direct, shortens the squeezing time, improves mud cake output and solid content.There are some through holes on following roller part surface, and inside is provided with water container, and water container is installed on the open tube of shutoff at one end, and open tube connects roller by bearing and as the mandrel of roller, open tube is fixed on the frame motionless.The other end of roller connects transmission mechanism with drive roller by shaft coupling.When carrying out sludge dewatering, the water that squeezes out is flowed in the water containers by some through holes of roller surfaces, concentrates by open tube and discharges, solved two rollers to press-dehydrating can't draining technical barrier.Upper roller parts two ends are provided with slide block and place on the rack-mounted guide rail, slide block can slide along guide rail, and self-operated regulator is connected with slide block, according to the thickness automatic pressure regulation of mud cake, and can meet the different needs according to mud manual regulation original pressure of different nature.Row's output shaft connects the upper roller parts by universal coupling on the transmission mechanism, the height displacement can appear in roller under the operating mode of different hmces and different initial pressures, uses universal coupling to solve the transmission displacement problem that roller axis and transmission mechanism output shaft axis angle and change in location cause.
