Abstract
The invention relates to a pitch changing drum screen separator which comprises a spiral conveyor, a screen frame, a drum screen mesh and an air separation chamber. The spiral conveyor is arranged at one end of the screen frame, and a center shaft of the spiral conveyor penetrates from one end of the screen frame to the other end of the screen frame and is fixedly installed in a supported mode. The drum screen mesh is arranged on the center shaft of the spiral conveyor, a material inlet of the drum screen mesh is connected with a material outlet of the spiral conveyor, and internal spiral blades are arranged on the inner wall of the drum screen mesh. Mesh holes are formed on the drum screen mesh and are used for pellet materials to fall to form pellet material flow curtains in the conveying process. The air separation chamber is arranged under the drum screen mesh and is used for separating the pellet material flow curtains in an air separation mode. The pitch changing drum screen separator is characterized in that the screw pitch of the internal spiral blades arranged on the drum screen mesh tapers gradually in the advancing direction of the pellet materials. By adopting the pitch changing drum screen separator, the pellet materials can form the pellet material flow curtains with uniform thickness, the air separation effect is led to be excellent, large grains, small grains and fine dust in the pellet materials can be quickly and thoroughly separated, and accordingly clean and uniform pellet materials can be obtained.
Description
Technical field
The present invention relates to a kind of ball material separation equipment, specifically a kind of varying pitch trommel separator that bulky grain in the ball material, granule, fine dusts can be separated to obtain the ball material of cleaning and uniformity.
Background technology
At mining equiment, metallurgical equipment, cement machinery, various occasions such as shot-blast apparatus, abrasive blast equipment all need the bulky grain in the ball material, granule, fine dusts are separated to obtain the ball material of cleaning and uniformity.Trommel separator is separation equipment commonly used now, it carries the ball material by the internal helical blades that is arranged on cylinder screen inside, ball material hole from the cylinder screen in course of conveying falls, form ball materials flow curtain, by selection by winnowing the bulky grain in the ball material, granule, fine dusts are separated then.But there is the inhomogeneous problem of ball materials flow curtain in existing trommel separator in practical work process, separating effect is not very desirable.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of varying pitch trommel separator is provided, its simple and ingenious structure, can make the ball material form the uniform ball materials flow of thickness curtain, make that the selection by winnowing effect is better, be conducive to the size particles in the ball material and fine dusts are separated rapidly completely, obtain the uniform ball material of the needed cleaning of technological requirement.
According to technical scheme provided by the invention: the varying pitch trommel separator, comprise conveying worm, screen frame (unit), cylinder screen and selection by winnowing chamber, described conveying worm is installed in screen frame (unit) one end, and the central shaft of conveying worm is through to the screen frame (unit) other end and supports from screen frame (unit) one end and installs and fixes; Described cylinder screen is installed on the central shaft of conveying worm, and the charging aperture of cylinder screen is connected with the discharging opening of conveying worm, and the cylinder screen inwall is provided be used to the internal helical blades that is fed forward the ball material; Described cylinder screen is provided with mesh, and described mesh is used for the ball material and falls formation ball materials flow curtain at course of conveying; Described selection by winnowing chamber is arranged under the cylinder screen, and the selection by winnowing chamber is used for that ball materials flow curtain is carried out selection by winnowing and separates; It is characterized in that: the pitch of the internal helical blades on the described cylinder screen along ball material direction of advance from large to small.
The present invention compared with prior art, advantage is: simple and ingenious structure of the present invention, by with the pitch of the internal helical blades on the cylinder screen along ball material direction of advance form from large to small, make ball materials flow curtain keep evenly at length direction, the effect of guaranteeing ball material separation screening is better, improved screening efficiency greatly, make that the ball material after the screening is more evenly clean, better meet technological requirement.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure: the varying pitch trommel separator among the embodiment mainly is made up of conveying worm 1, screen frame (unit) 2, cylinder screen 3 and selection by winnowing chamber 5, described conveying worm 1 is installed in screen frame (unit) 2 one ends, and the central shaft of conveying worm 1 is through to screen frame (unit) 2 other ends and supports from screen frame (unit) 2 one ends and installs and fixes; Described cylinder screen 3 is installed 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 inwalls are provided be used to the internal helical blades 4 that is fed forward the ball material; Described cylinder screen 3 is provided with mesh, and described mesh is used for the ball material and falls formation ball materials flow curtain 6 at course of conveying, and the pitch of described internal helical blades 4 along ball material direction of advance from large to small; Described selection by winnowing chamber 5 is arranged under the cylinder screen 3, and selection by winnowing chamber 5 is used for that ball materials flow curtain 6 is carried out selection by winnowing and separates.
During concrete the application, the ball material delivers in the cylinder screen 3 by conveying worm 1, cylinder screen 3 rotates under the drive of conveying worm 1 central shaft, the internal helical blades 4 of cylinder screen 3 inside is fed forward the ball material, and the ball material falls the mesh from cylinder screen 3 in course of conveying and forms ball materials flow curtain 6.Because the pitch of the internal helical blades 4 on the cylinder screen 3 along ball material direction of advance from large to small, make the screening ball material amount basically identical that each position, cylinder screen 3 front and back is in the longitudinal direction born like this, the ball material that falls by the mesh on the cylinder screen 3 can form the ball materials flow curtain 6 of thickness uniformity along the length direction of cylinder screen 3, make that the selection by winnowing effect is better, be conducive to the size particles in the ball material and fine dusts are separated rapidly completely, obtain the uniform ball material of the needed cleaning of technological requirement.
