Abstract
The invention discloses an efficient heat transfer cast steel drying cylinder and relates to the technical field of paper drying in the papermaking industry. The efficient heat transfer cast steel drying cylinder is characterized in that two ends of a cast steel cylindrical cylinder body are respectively fixedly connected with a left supporting shaft and a right supporting shaft through a left circular head and a right circular head; a heat preservation inner container is arranged in the cylinder body located between the left circular head and the right circular head; and at least ten through holes are uniformly distributed in the circumferential direction of the cylinder body. Heat transfer sleeves are respectively welded in the through holes, electric heating pipes are respectively arranged in the heat transfer sleeves, the heat transfer sleeves respectively penetrate into the through holes of the left circular head, the outer ends of the electric heating pipes are respectively fixedly connected with the left circular head through fixed parts, and super-conduction materials are filled in the through holes located between the heat transfer sleeves and the cylinder body. According to the efficient heat transfer cast steel drying cylinder, the electric heating pipes arranged in the heat transfer sleeves are adopted to supply heat sources, and heat generated by the electric heating pipes after the electric heating pipes are powered on is fast conducted to the outer surface of the cast steel cylinder body with good heat preservation perforamnce through the super-conduction materials; and the electric heating pipes are easy to replace, the super-conduction materials are fast in heat transfer, and temperature difference at two ends is small.
Description
Technical field
The present invention relates to the paper drying technology field of paper industry.
Background technology
Drying cylinder is oven dry, the modular system parts for paper industry, and existing drying cylinder adopts steel plate to make shell mostly, and two ends connect back shaft respectively, feed high-temperature steam in cylindrical shell, makes the drying cylinder surface reach the high temperature of baking needed.Because adopt high-temperature steam to heat, temperature is wayward, heat energy loss is big etc.
Summary of the invention
The object of the invention is to propose a kind of employing electrical heating, and the high efficient heat transfer cast steel drying cylinder of heat transfer efficiency.
The present invention includes the cast steel cylindrical tube, on the fixedly connected left side of difference, the two ends of described cylindrical shell, right circular head, on a described left side, the outer end of right circular head is a fixedly connected left side respectively, right back shaft, on a left side, in the cylindrical shell between the right circular head heat-preservation liner is set, circumferential uniform at least ten through holes at described cylindrical shell, axially being parallel to each other of the axial and described cylindrical shell of each through hole, in each through hole, weld the heat transfer sleeve pipe respectively, in each heat transfer sleeve pipe, electrothermal tube is set respectively, each sleeve pipe that conducts heat is set in respectively in the through hole of left circular head, fixedly connected with left circular head by fixture respectively in the outer end of each electrothermal tube, can superconductor in each through hole between heat transfer sleeve pipe and the cylindrical shell.
The electrothermal tube of this practical employing device in the heat transfer sleeve pipe provides thermal source, the heat that the energising back produces conducts to the cast steel barrel outer surface of good heat preservation performance fast by superconductor, this practical electrothermal tube is easy to change, and superconductor conducts heat fast, and two ends have a narrow range of temperature.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is I portion enlarged drawing among Fig. 1.
The specific embodiment
As shown in Figure 1, 2, fixedly connected left circular head 2 and right circular head 3 respectively at the two ends of cast steel cylindrical tube 1, fixedly connected left back shaft 4 and right back shaft 5 respectively in left and right circular head 2,3 outer end.In the cylindrical shell 1 between left and right circular head 2,3 heat-preservation liner 6 is set.
At circumferential uniform 12 through holes 7 of cylindrical shell 1, axially being parallel to each other of the axial and cylindrical shell 1 of each through hole 7 welded heat transfer sleeve pipe 8 respectively in each through hole 7, in each heat transfer sleeve pipe 8 electrothermal tube 9 is set respectively.Offer 12 corresponding through holes on left circular head 2 respectively, the outer end of each sleeve pipe 8 that conducts heat is set in respectively in the through hole of left circular head 2, fixedlys connected with left circular head 2 by fixture 10 respectively in the outer end of each electrothermal tube 9.
In each through hole 7, can superconductor 11 in the through hole between heat transfer sleeve pipe 8 and the cylindrical shell 1.
