Embodiment Construction

[0016] Below in conjunction with accompanying drawing, the present invention will be further described.

[0017] figure 1 As shown, it is a schematic cross-sectional structure diagram of the transverse annular cloth heat conduction channel of the present invention; figure 2 shown, is figure 1 The schematic diagram of the structure along the line A-A. combine two Figure 1 From the looks of it, the cylinder block includes a left shaft 1, a bearing 2, a spoke 3, a cylinder wall 5 and a right shaft 8. Wherein, the inner sides of both ends of the cylinder wall 5 are respectively fixedly connected with the two spokes 3, and the middles of the spokes 3 on both sides are respectively fixedly connected with the left shaft 1 and the right shaft 8, and the left shaft 1 and the right shaft 8 may be the same shaft; Bearings 2 are arranged on the outer sides of the shaft 1 and the right shaft 8 respectively. In the cylindrical cylinder wall 5, a number of horizontal heat conduction p...

Abstract

The invention discloses a normal-pressure multichannel papermaking drying cylinder which comprises a cylinder body. The drying cylinder is characterized in that a plurality of heat conducting channels which are uniformly distributed are laterally or longitudinally arranged in the cylindrical cylinder wall of the cylinder body; one end of each heat conducting channel is communicated with a steam input pipe, and the other end is communicated with a condensed water output pipe; and the steam input pipe and the condensed water output pipe are respectively communicated with a steam inlet and a condensed water outlet of a rotary joint. When steam enters the heat conducting channels of the cylinder body of the drying cylinder with the structure, the cylindrical cylinder wall of the cylinder body emits heat, heat is transferred to wet paper to be dried on the surface of the cylinder wall, and the wet paper is heated and water evaporates, so that the purpose of drying is achieved. As the drying cylinder body adopts an open structure, and pressure only exists in the heat conducting channels, the drying cylinder body does not belong to a pressure container. The drying cylinder belongs to a normal-pressure drying cylinder, has a simple structure, is high in temperature and heat transfer efficiency, low in weight, smooth in steam flowing and condensed water discharging, and low in manufacture cost.

Description

technical field [0001] The invention relates to a drying apparatus, especially a paper drying cylinder in a papermaking facility. Background technique [0002] In the current common papermaking facilities, the drying section is the main energy-consuming part of the paper machine, and the dryer is the main part of the drying section of the paper machine. The main structure of the existing drying cylinder includes a cylinder body, a transmission shaft, a rotary joint for entering and exiting steam and condensed water, a siphon for discharging condensed water, and a heat preservation device. The main task of the drying cylinder is to dry the wet paper sheets passing through the surface of the cylinder. In the process of drying wet paper sheets, the drying cylinder with this structure generally has the problem of poor drainage. If the condensed water in the drying cylinder is not properly drained, it will accumulate in the drying cylinder. When the rotation speed is high, the c...
