Summary of the invention
Technical problem to be solved by this invention is: a kind of spiral pusher device of horizontal spiral discharge sedimentation centrifuge is provided, and this spiral pusher device can make the solid phase water content of discharge lower.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of spiral pusher device of horizontal spiral discharge sedimentation centrifuge, the mandrel that comprises hollow, this mandrel rotates and is installed in bowl and is driven by power set, the outer wall of this mandrel is provided with spiral helicine pusher blade, this pusher blade comprises cylindrical section and frustum of a cone section, be provided with feed cavity in the inner chamber of mandrel, this feed cavity is communicated with the screw rod space outerpace by relief hole, be installed with striker plate on the outer wall of described mandrel, this striker plate is positioned at the cylindrical section of pusher blade and the junction of frustum of a cone section, there is the pusher gap between the outer rim of this striker plate and drum inner wall, this pusher gap is greater than the gap between pusher blade outer rim and drum inner wall, also be provided with opening on this striker plate, form the material flow channel between this opening and drum inner wall.
As a kind of preferred scheme, described striker plate is the fan annular.
As a kind of preferred scheme, two opening's edges of the opening of the striker plate of described fan annular are provided with the right angle flanging.
As a kind of preferred scheme, the overbending direction of the right angle flanging of two opening's edges of described opening is contrary.
As a kind of preferred scheme, the outer axial face radius of setting mandrel is made as r, and the outer rim radius of pusher blade is R, fanning annular striker plate exradius is R1, interior radius of circle is r1, and the central angle of fanning annular striker plate is θ, and there is following relational expression in above-mentioned each parameter:
After having adopted technique scheme, effect of the present invention is: on the outer wall due to described mandrel, be installed with striker plate, this striker plate is positioned at the cylindrical section of pusher blade and the junction of frustum of a cone section, there is the pusher gap between the outer rim of this striker plate and drum inner wall, this pusher gap is greater than the gap between pusher blade outer rim and drum inner wall, also be provided with opening on this striker plate, form the material flow channel between this opening and drum inner wall.Therefore, the solid phase deposited promotes when entering into frustum of a cone section through the cylindrical section of pusher blade, first by striker plate, blocked, because striker plate is provided with opening, this is opened between drum inner wall and forms the material flow channel, and the space that the existence of striker plate can be passed through solid phase so reduces suddenly, makes solid phase push herein and further be compressed, thereby the degree of comparing current existing spiral pusher device extrusion dehydration is higher, thereby make the solid phase water content of discharge lower.
Two opening's edges of opening due to the annular striker plate of described fan are provided with the right angle flanging again, thereby can strengthen the intensity of striker plate opening part, guarantee the work of striker plate long-term stability.
Because the outer axial face radius of setting mandrel is made as r, the outer rim radius of pusher blade is R again, and fanning annular striker plate exradius is R1, and interior radius of circle is r1, and the central angle of fanning annular striker plate is θ, and there is following relational expression in above-mentioned each parameter:
can determine size, openings of sizes and the pusher blade of striker plate, the relation of mandrel under this relational expression, make preferably scope of spatial variations to that solid phase can pass through.
