Abstract
The utility model discloses a horizontal helical centrifuge comprising a rotary drum and a helical conveyor. The rotary drum comprises a straight cylindrical front separating rotary drum and a rear separating drum, wherein one end of the rear separating rotary drum away from the front separating rotary drum is a slag outlet; the slag outlet is provided with a tapered press block; the other side of the tapered press block corresponding to the slag outlet is provided with a tapered press plate; a separating chamber of the front separating rotary drum is provided with a squirrel-cage-shaped small blade cylinder; the squirrel-cage-shaped small blade cylinder is provided with a plurality of small blades on the periphery thereof; and an inclined angle is formed between the small blades a normal of squirrel-cage-shaped small blade cylinder. With the straight cylindrical front and rear separating rotary drums, material can be remained in the rotary drum for a longer time, so a sedimentation area is enlarged, processing amount of material is increased, a problem of sediment return in the tapered rotary drum is avoided and higher separating elements are achieved. With the arrangement of the squirrel-cage-shaped small blade cylinder on the front separating rotary drum, time for suspension liquid entering the sediment area is delayed, so clarity of liquid phase is improved.
Description
Technical field
The utility model relates to a kind of centrifugal separating device, relates to specifically a kind of Horizontal helical type centrifuge with higher height reason efficiency, separating factor.
Background technology
Existing horizontal screw centrifuge generally comprises rotary drum and is positioned at the auger conveyor of rotary drum, by the cylinder body outer wall of auger conveyor and the inwall of rotary drum, form separation chamber, material enters into separation chamber by charging aperture, speed discrepancy due to auger conveyor and rotary drum, material is realized Separation of Solid and Liquid in separation chamber, wherein, rotary drum comprises and makes the effectively separated cylinder rotary drum of material and be convenient to make solid formation after separated and the rotary drum (cone-element) of liquid phase thing discharge.The cylinder rotary drum length of carrying out the effective separation of material due to existing Horizontal helical type centrifuge is shorter, make the time of staying of material in separation chamber shorter, affected treatment effeciency, simultaneously, also easily there is the backflow phenomenon of sediment in the rotary drum (cone-element) section of discharging for separating of rear material, has affected treatment effect.
Utility model content
For overcoming above-mentioned defect, the utility model aims to provide and a kind ofly can improve treatment effeciency, also can improve the straight barrel type horizontal screw centrifuge for the treatment of effect simultaneously.
For achieving the above object, the technical solution adopted in the utility model is: a kind of Horizontal helical type centrifuge, comprise a rotary drum and the auger conveyor that is positioned at rotary drum, the cylinder body outer wall of described auger conveyor has helical form screw feeder, described rotary drum comprises the front separator drum of a straight barrel type, between the cylinder body outer wall of described auger conveyor and the inwall of rotary drum, it is separation chamber, it is characterized in that described front separator drum is also connected with the rear separator drum of a straight barrel type, described rear separator drum is slag notch away from one end of front separator drum, slag notch has a tapered squeezing piece, the opposite side of the corresponding slag notch of tapered squeezing piece has a tapered squeezing plate.
In the separation chamber of described front separator drum section, have one section of squirrel-cage leaflet cylinder, described squirrel-cage leaflet cylinder along the circumferential direction has some vanelets, and the normal of described vanelets and squirrel-cage leaflet cylinder is inclined angle alpha.
Adopted Horizontal helical type centrifuge of the present utility model, owing to having adopted the forward and backward separator drum of straight barrel type, make the time of staying of material in rotary drum longer, improved settling area, material treating capacity is the more than 1.5 times of existing common Horizontal helical type centrifuge, and avoided rotary drum (cone-element) section sediment backflow phenomenon, can make drum speed greatly improve, have higher separating factor, and be provided with squirrel-cage leaflet cylinder in front separator drum section, utilize inclined plate sedimentation principle, can delay the time that suspension enters decanting zone, improve the clarity of liquid phase.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of squirrel-cage leaflet cylinder of the present utility model.
In figure: 1-rotary drum, 2-auger conveyor ，3-separation chamber, separator drum before 4-, separator drum after 5-, 6-slag notch, 7-tapered squeezing piece, 8-tapered squeezing plate, 9-squirrel-cage leaflet cylinder, 10 vanelets, 11-screw feeder.
The specific embodiment
As shown in Figure 1, the utility model discloses a kind of Horizontal helical type centrifuge, comprise a rotary drum 1 and the auger conveyor 2 that is positioned at rotary drum 1, the cylinder body outer wall of described auger conveyor 2 has helical form screw feeder 11, described rotary drum 1 comprises the front separator drum 4 of a straight barrel type, it between the inwall of the cylinder body outer wall of described auger conveyor 2 and rotary drum 1, is separation chamber 3, its innovative point is that described front separator drum 4 is also connected with the rear separator drum 5 of a straight barrel type, described rear separator drum 5 is slag notch 6 away from one end of front separator drum 4, described slag notch 6 has a tapered squeezing piece 7, the opposite side of the corresponding slag notch 6 of described tapered squeezing piece 7 has a tapered squeezing plate 8.
Material enters behind separation chamber 3, utilize the speed discrepancy of rotary drum 1 and auger conveyor 2, heavy solid composition can flow to the inwall of rotary drum 1, and to slag notch 6, flow under the drive of screw feeder 11, final by the extruding of tapered squeezing plate 8, solid composition flows out slag notch 6, and the more frivolous liquid the being separated part position on solid composition of proportion is blocked by tapered squeezing piece 7, by discharging opening, discharges.Owing to thering is front separator drum 4 and the rear separator drum 5 of straight barrel type, make the time of material 3 interior stops in separation chamber longer, improved settling area, with tapered squeezing plate 8, replace the rotary drum (cone-element) in traditional centrifuge simultaneously, avoided sediment backflow phenomenon.
As depicted in figs. 1 and 2, another innovative point of Horizontal helical type centrifuge of the present utility model is to have one section of squirrel-cage leaflet cylinder 9 in the separation chamber 3 of 4 sections of described front separator drum, described squirrel-cage leaflet cylinder 9 along the circumferential direction has some vanelets 10, described vanelets 10 is inclined angle alpha with the normal of squirrel-cage leaflet cylinder 9, and the angle that inclination angle adopts is conventionally: α=60 ± 5 degree.Solid particle in suspension is first encountered vanelets 10 under the effect of centrifugal force, and along vanelets 10 obliquely flows to the inwall of front separator drum 4, like this, vanelets 10 can delay the time that suspension enters into decanting zone, has effectively improved the clarity of liquid phase.
