Summary of the invention
The utility model is at the existing weak point that the horizontal helical type centrifuge is poor at the existing above-mentioned solid-liquid separation effect of the work of Separation of Solid and Liquid, the centrifuge work efficiency is low that is used for Separation of Solid and Liquid, and a kind of good effect of separating solid from liquid, laminar flow horizontal helical type centrifuge that the centrifuge work efficiency is high are provided.
The technical solution adopted in the utility model is finished in the following way: laminar flow horizontal helical type centrifuge comprises feed pipe, support, rotating cylinder, rotating shaft, screw feeder and differential transmission systems, screw feeder places in the rotating cylinder, the rotating shaft of rotating cylinder two ends is contained on the bearing block of support by bearing, on the front end cover plate of rotating cylinder, be provided with adjustable liquid outlet, promptly regulate the moisture content of slagging tap so that regulate water depth, on the rear-end plate of rotating cylinder, be provided with slag notch; Screw feeder comprises tubular axis, shunting chamber, sepage chamber and precipitation chamber, wherein, the shunting chamber is made up of the end face that is fixed on the tubular axis in scalene cone body, shunt catheter and sepage chamber, shunt catheter is located on the scalene cone body, the shunt catheter that is located on the scalene cone body is the excess extension shape, and the bus of scalene cone body becomes 20 °~40 ° angles with the axis of tubular axis; The sepage chamber is located at the conical section of screw feeder, and the sepage chamber is made of grizzly bar and the dividing plate that is provided with liquid-leadage hole, and grizzly bar is fixed on the dividing plate, and dividing plate is fixed on the tubular axis; The precipitation chamber is located at the cylindrical section of screw feeder, the precipitation chamber is made of several sloping plate deposition spacer rings, strand cage, end casing, water conservancy diversion clinohedral, the inner of wherein twisting cage connects with sloping plate deposition spacer ring outer, the strand cage can be different different with processing requirements according to treatment fluid, if single head or bull, and height, the pitch of strand cage are also different thereupon.
During work, treatment fluid enters the screw feeder from feed pipe, and the scalene cone body in the screw feeder to rotating cylinder madial wall place, is pushed a large amount of direct drainages of solid content to slag notch by the strand cage immediately; Be in the lower liquid of the solid grain of internal layer concentration and flow into the precipitation chamber by shunt catheter; At several sloping plate deposition spacer rings of setting up of precipitation chamber shortened according to the sloping plate deposition principle treat liquid attached wall of sediment time in fixing level greatly.Owing in the precipitation chamber, do not establish the aperture plate cylindrical shell, when producing the differential rotation, reduced to stir solid grain sedimentary deposit, solid grain sedimentary deposit and liquid layer are effectively separated, make clear water liquid level generation laminar flow, effectively improved the Separation of Solid and Liquid rate of centrifuge.
The utility model is compared with the existing horizontal helical type centrifuge that is used for Separation of Solid and Liquid, has Separation of Solid and Liquid rate height, good effect of separating solid from liquid, and fluid is limpid, and the moisture content of slagging tap is low, and the Separation of Solid and Liquid treating capacity is big, characteristics such as effect height.
