(x-66R/93)2+(y+130R/93)2=(40R/93)2；Wherein, 74R/93≤x≤106R/93, -166R/93≤
y≤-91R/93。
Further, the discharging opening is set to 5.
The invention allows for a kind of horizontal spiral discharge sedimentation centrifuge, including straight rotary drum, installed in the straight rotary drum
The cone rotary drum of one end and the conveyor screw being arranged in the cone rotary drum, the periphery wall of the conveyor screw are provided with helical blade, institute
State and feed pipe is provided with conveyor screw；The charging socket for communicating as described above and with the feed pipe is additionally provided with the conveyor screw
Body.
Further, the Spiral distribution pitch of the discharging opening is equal with the pitch of the helical blade.
Further, one end of the discharging opening is located at the root of the helical blade.
The beneficial effects of the present invention are：
Horizontal spiral discharge sedimentation centrifuge of the invention, streamlined discharging opening is set by charging tube cylinder,
When being centrifuged to suspension, material enters into charging tube cylinder from feed pipe, as the high speed of rotary drum rotates, suspension
Respectively CENTRIFUGAL ACCELERATING, quickly discharging are realized from discharging opening；Because discharging opening is set to streamlined discharging opening, rotation streamlined is constituted
Discharging, in this way, perturbing property when suspension discharges to fluid is also considerably reduced, more meets the waterpower distribution shape in hydrodynamics
Condition, so that the local turbulent condition for changing this region is laminar condition, improves horizontal screw centrifuge centrifugation point to a certain extent
From quality；It is more laborsaving and it is more smoothly to discharge, so that motor more saves power, reach the effect of energy-conservation.
Brief description of the drawings
In order that the purpose of the present invention, technical scheme and beneficial effect are clearer, the present invention provides drawings described below and carries out
Explanation：
Fig. 1 is the structural representation of horizontal spiral discharge sedimentation centrifuge embodiment of the invention；
Fig. 2 is the structural representation for feeding tube cylinder；
Fig. 3 is the profile structural representation of discharging opening.
Specific embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art can be with
It is better understood from the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
As shown in figure 1, being the structural representation of horizontal spiral discharge sedimentation centrifuge embodiment of the invention.The present embodiment
Horizontal spiral discharge sedimentation centrifuge, including straight rotary drum 1, the cone rotary drum 2 installed in the one end of straight rotary drum 1 and be arranged on cone rotary drum
Conveyor screw in 2, the periphery wall of conveyor screw is provided with helical blade 3, and feed pipe 4 is provided with conveyor screw, is additionally provided with conveyor screw
The charging tube cylinder 5 communicated with feed pipe 4.
The charging tube cylinder of the present embodiment, including cylinder body 6, cylinder body 6 are provided with multiple discharging openings 7, discharging opening 7
It is streamlined discharging opening, and all of discharging opening 7 is distributed in the shape of a spiral, the discharging opening 7 of the present embodiment is set to 5.This implementation
The Spiral distribution pitch of the discharging opening 7 of example is equal with the pitch of helical blade 3, and one end of discharging opening 7 is located at helical blade 3
The discharging opening 7 of root, i.e. the present embodiment, is radially angularly distributed, vertically equal pitch distribution.
