LYR Spiral preheater of paper machinery

Oblique spiral preheater is a high concentration of hydrogen peroxide bleaching system, supporting equipment for the high concentration of warm-up and delivery of pulp. Concentrated in the high concentration pulp slurry into the mouth from the preheater into the spiral ramp, the role of the spiral blade to the mouth of a slurry delivery, while preheating the pulp by steam, when the bleaching of pulp to the required temperature, and then from the follow-up to the high plasma concentration of population fall into the mixer. Oblique spiral preheater in the specially designed spiral piece of pulp can be effectively in promoting the loose, turning the pulp, the pulp uniform heating and improve the quality of bleached pulp. Mainly by the Oblique spiral preheater tube, shaft, frame, bearing, gear and other components. 1, the cylinder is inclined spiral heater main part of the installation was angled like the cylinder on the pulp out of welded pipes, saddle, steam inlet and other components, the installation of the two Z-side support flange. Cylinder made of stainless steel plates welded. 2, screw axis is not continuous broken by a special helical structure, conveying the pulp at the same time, effective loose, turning the pulp, paper pulp to promote uniformity of preheating, to ensure the quality of bleached pulp. 3, the bracket is divided into front and rear support bracket for supporting the entire device, the steel welded together, form a support structure and height can be adjusted according to the technical arrangement. 4, installed in the cylinder at both ends of bearing, bearing with double row radial spherical roller bearings, grease lubrication. 5, gear motor and double by the slow roller chains, gear motor through roller chain drive screw axis, compact structure, easy maintenance.
