Abstract
The invention discloses a horizontal screw centrifuge. The horizontal screw centrifuge comprises a rotary drum and a screw conveyor positioned in the rotary drum. The rotary drum comprises straight drum type front and back separation rotary drums, a tapping hole is formed in one end of the back separation rotary drum, which is far away from the front separation rotary drum, the tapping hole is provided with a conical extrusion block, and a conical extrusion plate is arranged on the other side of the tapping hole, which is corresponding to the conical extrusion block. A section of squirrel cage type small blade cylinder is arranged in a separation chamber of the front separation rotary drum section and provided with a plurality of small blades circumferentially, and included angles are formed by the normal of the squirrel cage type small blade cylinder and the small blades. According to the horizontal screw centrifuge, the straight drum type front and back separation rotary drums are adopted, so that materials can stay in the rotary drum for a long time, the settlement area is improved, the material treating capacity is high, and settled slag backflow at a conical rotary drum section is avoided, separation factors are provided; and the squirrel cage type small blade cylinder is arranged at the front separation rotary drum section, so that suspension can be delayed to enter a settlement area, and the clarity of the liquid phase can be improved.
Description
Technical field
The present invention relates to a kind of centrifugal separating device, relate to specifically a kind of Horizontal helical type centrifuge with higher height reason efficient, separating factor.
Background technology
Existing horizontal screw centrifuge generally comprises rotary drum and is positioned at the auger conveyor of rotary drum, form the separation chamber by the cylinder body outer wall of auger conveyor and the inwall of rotary drum, material enters into the separation chamber by charging aperture, because the speed discrepancy of auger conveyor and rotary drum, material is realized Separation of Solid and Liquid in the separation chamber, wherein, rotary drum comprises the cylinder rotary drum that makes the material effective separation and the rotary drum (cone-element) of being convenient to make solid formation after separating and liquid phase thing to discharge.Because it is shorter that existing Horizontal helical type centrifuge carries out the cylinder rotary drum length of material effective separation, so that the time of staying of material in the separation chamber is shorter, affected treatment effeciency, simultaneously, also easily occur the backflow phenomenon of sediment for separating of the rotary drum (cone-element) section of rear material discharge, affected treatment effect.
Summary of the invention
For overcoming defects, the present invention 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 used in the present invention 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 the helical form screw feeder, described rotary drum comprises the front separator drum of a straight barrel type, be the separation chamber between the cylinder body outer wall of described auger conveyor and the inwall of rotary drum, it is characterized in that described front separator drum also is connected with the rear separator drum of a straight barrel type, described rear separator drum is slag notch away from an end of front separator drum, slag notch has a tapered squeezing piece, and the opposite side of the corresponding slag notch of tapered squeezing piece has a tapered squeezing plate.
Have one section squirrel-cage leaflet cylinder in the separation chamber of described front separator drum section, described squirrel-cage leaflet cylinder has some vanelets in the circumferential direction of the circle, and the normal of described vanelets and squirrel-cage leaflet cylinder is inclined angle alpha.
Adopted Horizontal helical type centrifuge of the present invention, 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, the material treating capacity is existing more than 1.5 times of common Horizontal helical type centrifuge, and avoided rotary drum (cone-element) section sediment backflow phenomenon, drum speed is improved greatly, have higher separating factor, and be provided with squirrel-cage leaflet cylinder in front separator drum section, utilize the inclined plate sedimentation principle, can delay the time that suspension enters the decanting zone, improve the clarity of liquid phase.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of squirrel-cage leaflet cylinder of the present utility model;
Among the figure: 1-rotary drum, 2-auger conveyor, 3-separation chamber, separator drum before the 4-, separator drum behind the 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 invention 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 is separation chamber 3 between the inwall of the cylinder body outer wall of described auger conveyor 2 and rotary drum 1, its innovative point is that described front separator drum 4 also is connected with the rear separator drum 5 of a straight barrel type, described rear separator drum 5 is slag notch 6 away from an end of front separator drum 4, described slag notch 6 has a tapered squeezing piece 7, and the opposite side of described tapered squeezing piece 7 corresponding slag notches 6 has a tapered squeezing plate 8.
After material enters 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 under the drive of screw feeder 11, flow to slag notch 6, final extruding by tapered squeezing plate 8, the solid composition flows out slag notch 6, and the more frivolous liquid that the is separated part position on the solid composition of proportion is blocked by tapered squeezing piece 7, discharges by discharging opening.Owing to having front separator drum 4 and the rear separator drum 5 of straight barrel type, so that the time of material 3 interior stops in the separation chamber is longer, improved settling area, replace rotary drum (cone-element) in traditional centrifuge with tapered squeezing plate 8 simultaneously, avoided the sediment backflow phenomenon.
As depicted in figs. 1 and 2, another innovative point of Horizontal helical type centrifuge of the present invention is to have one section squirrel-cage leaflet cylinder 9 in the separation chamber 3 of 4 sections of described front separator drum, described squirrel-cage leaflet cylinder 9 has some vanelets 10 in the circumferential direction of the circle, described vanelets 10 is inclined angle alpha with the normal of squirrel-cage leaflet cylinder 9, and the angle of inclination angle employing is usually: α=60 ± 5 degree.Solid particle in the suspension is run into first 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 the decanting zone, Effective Raise the clarity of liquid phase.
