Embodiment Construction

[0015] Further description will be made below in conjunction with the accompanying drawings and specific embodiments.

[0016] The present invention as figure 1 , as shown in 2, 3, and 4, is a pulp drying heat transfer oil cylinder for papermaking, which has a new type of heat transfer oil cylinder with double-sided inflow and double-side outflow. The 8 oil inlet main shaft connected to the 11 oil inlet groove and the 15 oil inlet groove connected to the right end of the 8 oil inlet spindle, and then the 11 oil inlet groove and the 15 oil inlet groove respectively flow into the first axial oil guide cavity of 13 and the second axial guide chamber of 14 The oil chamber realizes convective flow, and flows in and out from the 10 first radial oil outlet metal pipe at the left end of the 13 first axial oil guide chamber and the 9 second radial oil outlet metal pipe at the end of the 14 second axial oil guide chamber The main shaft with 8 oil outlets connected with the metal pipe f...

Abstract

The invention relates to the field of papermaking, and belongs to drying equipment. A double-inlet and double-outlet conduction oil drying cylinder comprises an inner cylinder of a cylinder body, an outer cylinder of the cylinder body, oil guiding cavities, an oil inlet main shaft, an oil outlet main shaft, outlet metal pipes, a transmission side shaft head and an operation side shaft head. The entire drying cylinder is made from a steel material, provided with 20 oil guiding cavity passages and 20 metal pipes, every two adjacent passages are partitioned through a welding partition plate, andthe tail ends of a first axial oil guiding cavity and second axial oil guiding cavity are closed; conduction oil flows into the right end of the first axial oil guiding cavity and flows out from the left end of the first axial oil guiding cavity and flows into the left end of the second axial oil guiding cavity and flows out from the right end of the second axial oil guiding cavity respectively, and the first axial oil guiding cavity and the second axial oil guiding cavity are provided with 10 inlets and 10 outlets respectively. The 20 inlets of the oil guiding cavities are directly connectedwith the passages, and the 20 outlets are communicated with the inner cylinder of the cylinder body and the oil outlet main shaft through the metal pipes. The double-inlet and double-outlet conductionoil drying cylinder has the advantages that the conduction oil convectively flows in the dying cylinder, so that the surface temperature of the drying cylinder is distributed more evenly, the temperature difference is reduced, and the quality of paper is improved.

Description

technical field [0001] The invention relates to a heat-conducting oil dryer, in particular to a heat-conducting oil dryer for paper pulp drying. Background technique [0002] Patent No. CN107217526A describes a steel welded heat-conducting oil dryer, in which the heat-conducting oil flows convectively in the oil-conducting cavity through the metal hose connected to the oil inlet tank, so that the surface temperature of the oil cylinder is evenly distributed, good paper quality is obtained, and materials are saved The loss of heat is reduced, and the utilization rate of heat is improved. However, the metal hoses are intertwined in the drying cylinder, the manufacturing process is complicated, and the phenomenon of unbalanced cylinder body occurs to the rotating drying cylinder. Beneficial effects: the present invention replaces the metal hose by utilizing the integrity of the channel, improves the stability of the drying cylinder in operation, and makes the temperature distr...
