Description
Technical field
The present invention relates to a kind of ball material separation equipment, specifically a kind of Screw-pitch-variablehole-pitch-variable hole-pitch-variable drum screen separator bulky grain in ball material, granule, fine dusts can being separated the ball material obtaining cleaning and uniformity.
Background technology
At mining equiment, metallurgical equipment, cement machinery, various occasion such as shot-blast apparatus, abrasive blast equipment, all needs the ball material separating the bulky grain in ball material, granule, fine dusts to obtain cleaning and uniformity.Trommel separator is now conventional separation equipment, it is by being arranged on the internal helical blades conveying ball material of cylinder screen inside, ball material falls from the hole cylinder screen in course of conveying, form ball stream curtain, then by selection by winnowing, the bulky grain in ball material, granule, fine dusts are separated.But there is the uneven problem of ball stream curtain in existing trommel separator, separating effect is not very desirable in practical work process.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of Screw-pitch-variablehole-pitch-variable hole-pitch-variable drum screen separator is provided, its simple and ingenious structure, ball material can be made to form thickness uniform ball stream curtain, make selection by winnowing effect better, be conducive to the size particles in ball material and fine dusts to be separated thoroughly rapidly, obtain the uniform ball material of cleaning required for technological requirement.
According to technical scheme provided by the invention: Screw-pitch-variablehole-pitch-variable hole-pitch-variable drum screen separator, comprise conveying worm, screen frame (unit), cylinder screen and selection by winnowing room, described conveying worm is arranged on screen frame (unit) one end, and the central shaft of conveying worm is through to the screen frame (unit) other end from screen frame (unit) one end and supporting is installed fixing; Described cylinder screen is arranged on the central shaft of conveying worm, and the charging aperture of cylinder screen is connected with the discharging opening of conveying worm, and cylinder screen inwall is provided with the internal helical blades for being fed forward ball material; Described cylinder screen is provided with mesh, and described mesh is used for ball material in course of conveying, falls formation ball stream curtain; Described selection by winnowing room is arranged on immediately below cylinder screen, and selection by winnowing room is used for carrying out selection by winnowing separation to ball stream curtain; It is characterized in that: along ball material direction of advance from large to small, the pitch-row of the mesh on cylinder screen along ball material direction of advance from large to small for the pitch of the internal helical blades on described cylinder screen.
compared with prior art, advantage is in the present invention: simple and ingenious structure of the present invention, by improving the structure of cylinder screen, by the pitch of the internal helical blades on cylinder screen along ball material direction of advance from large to small, the pitch-row of the mesh on cylinder screen along ball material direction of advance from large to small, ball stream curtain is made to keep evenly, guaranteeing that the effect of ball material separation screening is more excellent, substantially increasing screening efficiency at length direction, make the ball material after sieving more evenly clean, better meet technological requirement.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in the figure: the Screw-pitch-variablehole-pitch-variable hole-pitch-variable drum screen separator in embodiment forms primarily of conveying worm 1, screen frame (unit) 2, cylinder screen 3 and selection by winnowing room 5, described conveying worm 1 is arranged on screen frame (unit) 2 one end, and the central shaft of conveying worm 1 is through to screen frame (unit) 2 other end from screen frame (unit) 2 one end and supporting is installed fixing; Described cylinder screen 3 is arranged on the central shaft of conveying worm 1, and the charging aperture of cylinder screen 3 is connected with the discharging opening of conveying worm 1, and cylinder screen 3 inwall is provided with the internal helical blades 4 for being fed forward ball material; Described cylinder screen 3 is provided with mesh, described mesh is used for ball material in course of conveying, falls formation ball stream curtain 6, along ball material direction of advance from large to small, the pitch-row of the mesh on cylinder screen 3 along ball material direction of advance from large to small for the pitch of the internal helical blades 4 on described cylinder screen 3; Described selection by winnowing room 5 is arranged on immediately below cylinder screen 3, and selection by winnowing room 5 is for carrying out selection by winnowing separation to ball stream curtain 6.
During embody rule, ball material delivers in cylinder screen 3 by conveying worm 1, cylinder screen 3 rotates under the drive of conveying worm 1 central shaft, ball material is fed forward by the internal helical blades 4 of cylinder screen 3 inside, and ball material falls and forms ball stream curtain 6 in course of conveying from the mesh cylinder screen 3.
Due to the internal helical blades 4 on cylinder screen 3 pitch along ball material direction of advance from large to small, the pitch-row of the mesh on cylinder screen 3 along ball material direction of advance from large to small (mesh density namely on cylinder screen 3 is changed from small to big along ball material throughput direction), the screening ball doses making each position, cylinder screen 3 front and back in the longitudinal direction bear like this is basically identical, the ball material fallen by the mesh on cylinder screen 3 can form the ball stream curtain 6 of thickness uniformity along the length direction of cylinder screen 3, make selection by winnowing effect better, the size particles in ball material and fine dusts is conducive to be separated thoroughly rapidly, obtain the uniform ball material of cleaning required for technological requirement.
