Problems solved by technology

However, when the opening position Dmid is moved to the limit, it becomes a non-porous disc, because this will cause turbulent flow in the non-porous guide flow channel of the disc and the edge of the disc, and the separation effect will become poor.
[0003] According to the applicant's knowledge, there are existing structural design forms with round holes or semicircular holes on the edge of the disc, and the effect is not very obvious; and for the same size drum, when other parameters remain unchanged, the larger the disc diameter, the better the separation effect. The better, but increasing the diameter of the disc has an adverse effect, which will make the slag accumulation area of ​​the drum smaller, and the separated solid slag will easily block the guide channel of the semi-circular hole at the edge of the disc, making it impossible to separate

Embodiment 1

[0021] A kind of splitter disk in this embodiment, such as figure 1 As shown in Figure (a) and Figure (b), it includes a disc 1 and ribs 2 evenly distributed on the cone surface of the disc. The bottom edge of the cone surface of the disc 1 is provided with a set of long Slot 3.

[0022] The long grooves described in the embodiment of the present invention are opened obliquely along the tapered surface; and the inclination angle of the long grooves along the direction of the generatrix of the disc is 30°. During the clockwise high-speed operation of the drum, the solid slag is smoothly discharged from the inclined groove under the action of centrifugal force, which improves the slag discharge efficiency and does not cause solid slag accumulation. The notch aspect ratio of the long groove is 3-5. The half cone angle 4 of the disc 1 is 45°. The height of the ribs is 0.5-2.5 mm, which has a good solid-liquid separation effect through repeated experiments. The structure design...

Embodiment 2

[0024] A kind of splitter disk in this embodiment, such as figure 2 As shown in Figure (a) and Figure (b): it includes a disc 1'' and ribs 2'' evenly distributed on the cone surface of the disc, and the bottom edge of the cone surface of the disc 1'' is along the A group of long grooves 3'' are opened on the conical surface.

[0025] The long grooves described in the embodiment of the present invention are opened obliquely along the generatrix of the disc cone surface; and the inclination angle of the long grooves along the direction of the generatrix of the cone surface is -30°. During the clockwise high-speed operation of the drum, the solid slag is smoothly discharged from the inclined groove under the action of centrifugal force, which improves the slag discharge efficiency and does not cause solid slag accumulation. The notch aspect ratio of the long groove is 3-5. The half cone angle 4'' of the disc 1'' is 45°. The height of the ribs is 0.5-2.5 mm, which has a good s...

Embodiment 3

[0027] A kind of splitter disk in this embodiment, such as image 3 As shown in Figure (a) and Figure (b): including disc 1' and ribs 2' evenly distributed on the disc cone surface, the bottom edge of the cone surface of the disc 1' is set along the cone surface A set of long slots 3'.

[0028] The long groove described in the embodiment of the present invention is composed of a rectangular notch and an arc-shaped notch opened along the direction of the generatrix of the conical surface. The notch aspect ratio of the long groove is 3-5. The long groove 3' is set in the middle of the two ribs. The half cone angle 4' of the disc 1' is 30-45°. The height of the ribs 2' is 0.5-2.5 mm, which has a good solid-liquid separation effect through repeated experiments.

Abstract

The invention relates to a separator disc. The separator disc comprises a disc body and ribs which are uniformly distributed on a conical surface of the disc body; elongated slots are formed in the edge of the bottom of the conical surface of the disc body along the conical surface; and the length-width ratio of notches of the elongated slots is 1-7. The disc body is provided with the elongated grooves and is particularly provided with the oblique notches, for drums with the same size, the diameter (d) of the disc body can be greater, and therefore, the separating effect is improved; and when solid residues are accommodated to the edge of the disc body, even if a certain amount of the solid residues which are accumulated to the center exceed the edge of the disc body, as long as the elongated grooves are not completely blocked by the solid residues, a flow guide channel for material separation is smooth, and the separating effect of a separator can still be good. In addition, the scope of application of the separator to the solid residues of the separated materials is expanded, and the risk that a position, which is close to the edge of the disc, in a drum of the disc separator is blocked by the separated material solid residues is reduced.

Description

technical field [0001] The invention relates to a disc separator, in particular to a structural design of a disc separator, which belongs to the field of separators. Background technique [0002] Disc separator is a high-speed sedimentation centrifuge, which can quickly and effectively separate two liquids and one solid mixture with high speed and strong centrifugal force. Due to its high-efficiency separation characteristics, it has been widely used Used in shipbuilding, food, medicine, chemical, textile and environmental protection industries. After the separator is started, the motor drives the drum to rotate at a high speed through the vertical shaft system. After the material is passed, the separation effect of the material depends on the drum speed (n) and the disc diameter (d) of the separator without considering the characteristics of the material itself. , Disc half-cone angle (θ). In actual use, generally a plurality of diversion holes are opened on the disc, and...
