Abstract
The invention belongs to the field of centrifugal solid-liquid separators and particularly relates to a primary solid-phase outlet device of the centrifugal solid-liquid separators. The primary solid-phase outlet device is simple in structure and good in solid-phase material discharging effect. The technical scheme is that the solid-phase outlet device comprises a screw conveying shaft, screw blades arranged on the screw conveying shaft and a conic outer tube arranged outside the screw conveying shaft. The screw pitch of each screw blade gradually increases from a screw blade setting area to a screw blade conveying wiping area. A plurality of slag discharging ports are axially arranged along the screw conveying shaft. The distance between a large end of the conic outer tube and a mud blocking piece is recorded as A, the distance between each slag discharging port and the mud blocking piece is recorded as B, and A is larger than B.
Description
Technical field
The invention belongs to centrifugal separator for solid from liquid field, be specially an a kind of solid-phase outlet device of centrifugal separator for solid from liquid.
Background technology
Along with growth in the living standard, people more and more pay attention to environmental protection.Wastewater treatment embodies a particularly important link of environmental issue, and therefore centrifugal equipment for separating liquid from solid is more and more extensive in field ranges of application such as environmental protection, municipal wastewater process.Centrifugal separator for solid from liquid is by under driven by motor, according to the difference of different material eccentricity, various impurity is separated from water.
At present, most of centrifugal separator for solid from liquid be radial setting apart from solid-phase outlet, and helical blade rotates that the tangential velocity produced is comparatively large, and radial velocity is comparatively large, exports to be arranged on radial direction and to make to be separated in solid phase and be often mingled with more liquid, and separating effect is not good.
Summary of the invention
Main purpose of the present invention is to overcome deficiency of the prior art, provides a solid-phase outlet device of the centrifugal separator for solid from liquid that a kind of structure is simple, solid phase discharging effect is better.
Above-mentioned technical problem of the present invention is implemented by the following technical programs: an a kind of solid-phase outlet device of centrifugal separator for solid from liquid, comprise screw conveyor shaft, be arranged on the helical blade on screw conveyor shaft, be arranged on the conical outer tube outside screw conveyor shaft, helical blade pitch is extracted district by helical blade settling section to helical blade conveying and is increased gradually, axially several slag-drip openings are provided with along described screw conveyor shaft, the large end of conical outer tube is designated as A to the distance of mudflap, slag-drip opening is designated as B to the distance of mudflap, A ﹥ B, due to the effect of the gravity of solid formation itself, the axis adding last solid phase mud mouth is arranged, namely, solid formation adopts straight discharge, the discharge body that solid formation is quick and smooth can be made.
As preferably, B ︰ A=1 ︰ 5 ~ 3 ︰ 5.When the large end of conical outer tube remains unchanged to the distance A of mudflap, regulation span, can make the setting position of slag-drip opening improve, is beneficial to solid formation discharge body.
As preferably, described slag-drip opening is arranged on the small end of conical outer tube, is provided with gripper shoe in the radial direction along slag-drip opening; Described mudflap is positioned at the end of screw conveyor shaft, and the large end of conical outer tube is towards the direction contrary with mudflap position, and the small end of conical outer tube is towards the direction at mudflap place.
As preferably, be arranged with cylindrical outer body outside described conical outer tube, between cylindrical outer body and conical outer tube, form cavity.Under the centrifuge effect of High Rotation Speed, the setting of cylindrical outer body can improve the fastness of seperator entirety.
In sum, the present invention compared with prior art has the following advantages:
Structure of the present invention is simple, extracts district and increases gradually, therefore the setting position of slag-drip opening is improved, be beneficial to the quick smooth and easy discharge body of solid formation due to helical blade pitch by helical blade settling section to helical blade conveying.Secondly, be arranged on the cylindrical outer body outside conical outer tube, under the centrifuge effect of High Rotation Speed, the fastness of animal economy can be kept.
