Abstract
Disclosed is a feeding distribution plate of a vertical coal slime centrifuge. The feeding distribution plate belongs to the technical field of coal preparation equipment and is capable of adapting tolow feeding density, realizing pre-rotation of materials and reducing the axial speed of the materials. The scheme of the feeding distribution plate includes that an inner cavity of a conical body isin the shape of an inverted cone frustum, a conical vertex angle corresponding to the cone frustum ranges from 155 degrees to 170 degrees, guiding vanes are evenly distributed on the outer conical surface of the conical body, a projection on the outer conical surface of the conical body produced by the guiding vanes is circular arc-shaped, and an inclination direction of connecting lines at two ends of the circular arc is in accordance with the rotation direction of a spiral. The feeding distribution plate has the advantages of facilitating the reduction of the axial speed of feeding materials, increasing residence time of the materials in a dewatering area and reducing moisture of products due to the design of the cone frustum shape of the conical body and the selection of the conical vertex angle, speeding pre-rotation of feeding materials owing to the design of the circular arc shape of the guiding vanes, and further enabling the materials to reach or approach the rotation speed ofa sieving basket in the shortest time and then being evenly distributed into a feeding area on the upper portion of the sieving basket.
Description
Technical field
The utility model relates to a kind of vertical coal slime centrifuge pan feeding and carries out pretreated material distribution device, belongs to the cleaning unit technical field.
Background technology
Along with the raising of digging, coal preparation machine degree, the secondary slime amount that produces in fine fraction coal content and the coal separation process in the raw coal increases greatly.A lot of coal preparation plants influence user's economic and technical norms simultaneously because fine fraction product of coal moisture height (28～32%) has had a strong impact on the transportation of end product quality and winter, are problems anxious to be solved during coal separation is produced.At present, the trend of processing 3-0mm sized coal dehydration aspect is to adopt helical-conveyer centrifugal.The coarse slime dehydration is reclaimed the vertical helical conveyer centrifugal that is adopted and mainly is made up of transmission device, working portion, casing and lubricating system, material enters from vertical coal slurry centrifuge upper end feeding mouth, effect at gravity drops on the cloth awl, under the effect of helical blade, obtain the circumference tangential velocity and enter basket top material feeding region, under action of centrifugal force, continuously dewater.The tip circle angle of taper of existing cloth awl is less, linear pattern guide vane uniform distribution material, and material feeding region is bigger, drying zone is less, makes dewatering time shorter, and product moisture is higher, and, must under high concentration pan feeding condition, just can reach desirable dehydrating effect to technology pan feeding conditional request height.In centrifugal filtration Separation of Solid and Liquid process, in the centrifugal filtration process of particularly working continuously, make into pulp suspension to reach with the shortest time or, to promoting particles settling, quickening filter cake and generate very crucial near the rotating speed of basket.For this reason, reply vertical coal slurry centrifuge pan feeding distribution plate improves to adapt to low pan feeding concentration and to improve dehydrating effect.
Summary of the invention
Technical problem to be solved in the utility model provide a kind ofly adapt to low pan feeding concentration, realize to material pre-rotation, reduce the vertical coal slurry centrifuge pan feeding distribution plate of material axial velocity.
The technical scheme that solves the problems of the technologies described above is:
A kind of vertical coal slurry centrifuge pan feeding distribution plate, it is made up of cone and guide vane, its improvements are, cone cavity is the round platform tubular, the end face diameter of cone cavity is less than the bottom opening diameter of cone cavity, the height of round platform is 70-90mm, and the circular cone drift angle of round platform correspondence is 155 °～170 °, and cone is connected with screw top by bolt.
Above-mentioned vertical coal slurry centrifuge pan feeding distribution plate, described guide vane has a plurality of, evenly arranged evenly on the cone male cone (strobilus masculinus) respectively, its being projected as on the cone male cone (strobilus masculinus) is circular-arc, all circular arc top end points are on same circle, angle α between circular arc inside top end points and cone line of symmetry is 10 °～15 °, and the angle β between circular arc inside bottom end points and tapered sleeve line of symmetry is 20 °～25 °, and the incline direction of circular arc two ends line is consistent with the direction of rotation of spiral.
The vertical coal slurry centrifuge pan feeding distribution plate of this structure, the round platform tubular design of cone and the selection of tip circle cone angle make pan feeding more steady, be beneficial to and reduce the pan feeding axial velocity, prolong the service life of pan feeding distribution plate, increase material, reduce product moisture in the time of staying of drying zone; Design of the circular shape of guide vane and even distribution can be played guide effect and can quicken the pan feeding pre-rotation, material was reached with the shortest time or near the rotating speed of basket, be distributed to basket top material feeding region equably.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
Mark is as follows among the figure: cone 1, guide vane 2, connection screw 3
The specific embodiment
Consult Fig. 1,2, the pan feeding distribution plate is made up of cone 1 and 8 guide vanes 2.
8 guide vanes 2 are evenly arranged evenly on cone 1 male cone (strobilus masculinus) respectively, and perpendicular to cone 1 male cone (strobilus masculinus).Guide vane 2 being projected as on cone 1 is circular-arc, all circular arc top end points are on same circle, angle α between circular arc inside top end points and cone line of symmetry is 10 °～15 °, angle β between circular arc inside bottom end points and tapered sleeve line of symmetry is 20 °～25 °, and the incline direction of circular arc two ends line is consistent with the direction of rotation of spiral.Guide vane 2 surfaces scribble high-abrasive material.
The utility model is when work, the pan feeding distribution plate is installed in coal slime centrifuge spiral upper end by bolt, material enters from the centrifuge feeding mouth, drop on the pan feeding distribution plate in the effect of gravity and to have axial velocity, the material of falling plane on the distribution plate moves along the conical surface and has reduced the pan feeding axial velocity, under guide vane 2 effects, quicken the pan feeding pre-rotation and tangentially enter basket top material feeding region, material is reached or near the rotating speed of basket with the shortest time, material feeding region reduces to realize that initial stage high efficiency dehydration strengthens the adaptability of centrifuge to the influence of fluctuations of pan feeding moisture, the dehydration workspace increases, make the material dewatering time lengthening, reduce product moisture, improved dehydrating effect.This vertical coal slurry centrifuge pan feeding distribution plate can be by changing the angle matching relationship of cone 1 outside diameter and conical surface tip circle cone angle, guide vane 2 sizes and radian, guide vane 2 projection and cone 1 bottom surface radius on cone 1, make the series of products of multiple model, to satisfy the actual needs that different material is produced.
