The principle of work of this device is: when screw conveyor normally works, and first by the output speed of mass transport amount determination frequency control motor, to meet the minimum requirements of operational throughput for the best, avoids the insignificant wearing and tearing of helicallobe.Screw conveyor is driven by motor reducer, and transmission shaft is rotated by sprocket wheel chain-driving screw shaft, and the screw shaft of rotation promotes material and moved axially by the outside ring of the inner ring of rotary hearth furnace, completes the conveying of material.
Advantage of the present invention is:
(1) helicallobe adopts heat-resistant, wear-resistant resistant to corrosion material, inherently solves helicallobe easy to wear, the problem that service life is extremely short.
(2) by carrying out directly cooling to helicallobe and indirectly cooling the mode combined, improve the working environment that it is severe, vital effect is played to the premium properties playing its material.
(3) helicallobe adopts the version of bull, and on axle, rational angle design, while ensure that material high-efficiency exports, reduces the rate of wear of helicallobe.
(4) select frequency control motor as propulsion source, determine rational output speed according to mass transport amount, while meeting production requirement, by the normal wear extent control of helicallobe at minimum level.
(5) adjust the setting of cylinder, avoid heel and toe wear and the damage of helicallobe.Above taked measure produces collaborative effect: the bulk life time significant prolongation of screw conveyor, the frequency of helicallobe repair and maintenance is reduced greatly, maintenance cost significantly reduces, and improves the year operating rate of rotary hearth furnace manufacturing line simultaneously, reduce further the manufacturing cost of finished product.
