Abstract
The invention discloses a stepped continuous double-roll counter-pressing dehydrator, comprising a rack, a power unit and a transmission device, wherein the rack is provided with a plurality of press roll pairs; each press roll pair comprises an upper press roll (5) and a lower press roll (4) which are arranged in an up-down mode; the upper press roll and the lower press roll carry out rolling by a roll-to-toll rotating relay mode; and the press rolls which are adjacent at the left and right are arranged in a stepped mode. The stepped continuous double-roll counter-pressing dehydrator adopts stepped upper-lower two roll rotating counter-pressing dehydration, uses steps to transfer materials, and omits the traditional long filter cloth and a correcting device, the two-roll transferring is similar to the steel rolling principle, therefore, the stepped continuous double-roll counter-pressing dehydrator has the advantages of large pressing force and short pressing time and ensures low moisture content of a mud cake. The center of the lower roll is provided with a flushing system, the end surface thereof is provided with a water discharging port, so the technical difficulty of double-roll counter-pressing dehydration and water discharge.
Description
Technical field
The present invention relates to a kind of solid-liquid separation squeeze dehydration unit, especially for the staged continuous double-roller of sludge dewatering to pressing dehydrator.
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.At present, sludge dewatering is widely used to be belt filter press, these pressure filter substantially all are the tension force that relies on filter cloth to the material dehydration of exerting pressure, roller is not to pressing, so squeeze is minimum, thus 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, the squeezing effect is undesirable.Chinese patent CN201406369Y discloses a kind of continuous double-roller opposite-compacting type water extracter, it is provided with the pressure roller that upper and lower two row are arranged, material is carried out press dewatering, though solved the high problem of water ratio, but this device must use filter cloth, is provided with filter cloth tightening device and filter cloth deviation correcting device, and correction must be equipped with air compressor machine, electric control gear in addition, make machine become complicated, energy consumption is big.
Summary of the invention
For solving the problems of the technologies described above, the invention provides and a kind ofly need not to use long filter cloth, staged continuous double-roller simple in structure pressing dehydrator, make the solid-liquid separation in slag, the mud dewatering process more thorough, liquid holdup is extremely low in the slag mud.
The present invention has adopted following technical scheme: the staged continuous double-roller is to pressing dehydrator, comprise frame, power set and transmission mechanism, it is right that frame is provided with some pressure rollers, each pressure roller is to comprising the last pressure roller and the lower compression roller of upper and lower arrangement, upper and lower pressure roller is the roll-in of roll-to-roll rotation relay-type, and left and right adjacent pressure roller is arranged being staged.
Mid frame of the present invention is provided with scraper and discharge conveyor, and described scraper is positioned at a side-lower of pressure roller and facing to last pressure roller, the dehydration slag charge on the last pressure roller is scraped; Described discharge conveyor is and has a down dip shape between the adjacent lower compression roller in the left and right sides, with the dehydration slag charge on the last pressure roller scrape and be sent to back one pressure roller between.
Lower compression roller is hollow roller, is distributed with out fluid through-hole on the roll body, and hollow roller axis is provided with into water flushing arrangement, and water inlet flushing arrangement and frame are fixedly connected, and lower compression roller moves into water flushing device rotation and last pressure roller to pressure, and the lower compression roller end face is provided with water outlet; Water inlet is the open tube of an end shutoff towards Xian's device, and open tube is connected with water inlet pipe, the water outlet through hole of arranging on the lower tube body of described open tube; Described lower compression roller one end connects with transmission mechanism, and the lower compression roller inner chamber connects open tube by bearing, and open tube is fixed on the frame as the semiaxis of lower compression roller; The roll body of lower compression roller is divided into inside and outside two-layer, and outer roll body is the slag liquid sealing coat that is provided with micropore, and the internal layer roll body is provided with aperture formula slit.
Slide block is equipped with at the two ends of last pressure roller, 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.
Owing to adopted as above technical scheme, left and right adjacent pressure roller is arranged being staged, last pressure roller between the dehydration slag charge, by scraper, discharge conveyor slag, mud are scraped and to be delivered between next pair of rollers, need not to re-use long filter cloth, omitted tightening device and deviation correcting device simultaneously, simple in structure.Lower compression roller adopts special structure, and roll body is divided into inside and outside two-layer, and outer roll body is the slag liquid sealing coat that is provided with micropore, and the internal layer roll body is provided with aperture formula slit, and every pair of pressure roller is arranged above and below, and the water that squeezing is come out flows under the influence of gravity into lower compression roller inside.Lower compression roller inside is provided with into water flushing arrangement, water inlet is towards the open tube of Xian's device semiaxis as lower compression roller, Gu poison is motionless, the water outlet through hole of arranging on the lower tube body of open tube, when carrying out sludge dewatering, the water that squeezes out is flowed in the pressure roller by the roll body fluid hole, flow out through pressure roller bottom and lateral water outlet, the water outlet through hole that the flushing arrangement of intaking simultaneously can be intake through open tube washes the pressure roller body, this structure had both guaranteed not use the roller surface cleaning of long filter cloth, had solved the technical barrier of two rollers to the press-dehydrating draining again.The contact area is little between roller in the present invention, so it is big to have a squeeze force, the advantage that the squeezing time is short makes the discharging water ratio lower, improves mud cake output and solid content.The two ends of last pressure roller are equipped with slide block and are placed 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.The present invention is widely used in solid-liquid separation dehydration such as food-processing, sugar refinery, mine, environmental protection, sewage work; The vegetables extrusion dehydration of food factory, oil expression, the sugarcane in sugar refinery, beet squeezing, slag slurry separate, and the squeezing of meat product, oil crops, slag liquid separate, the pulp water in mine and the mud-water separation of Sewage Plant etc., particularly sludge of sewage treatment plants dehydration.
