Abstract
The utility model provides an efficient electric heating roller, and relates to the technical field of drying devices. The efficient electric heating roller comprises a roller body and transmission end shaft head combination pieces arranged at the two ends of the roller body. A plurality of U-shaped steel channels are evenly distributed on the inner wall of the roller body, the open end of each U-shaped steel channel is welded with the inner wall of the roller body in a sealing mode, an electric heat pipe is arranged in one end of each U-shaped steel channel, and an electric heat pipe protective cover is arranged at the outer end of the each electric heat pipe. A sealing cover is arranged at one end, far away from the electric heat pipes, of each U-shaped steel channel, and a pressing cover is arranged on the outer side of each sealing cover. The efficient electric heating roller is even in temperature, has no temperature difference at the two ends when having load, is superior to steam or heat conductive oil rollers, saves energy, and is friendly to the environment.
Description
Technical field
The utility model relates to drying plant technical field.
Background technology
Existing steam and heat conduction oiling roller need boiler, pipeline etc., and after having load, two ends temperature is uneven.Because boiler main will be used coal as the energy, not only service efficiency is low, and contaminated environment.
Utility model content
The utility model object is putting forth effort to solve temperature uneven problem in roll body two ends while having load, for related industry provides a kind of efficient electrical-heating roller that reduces energy loss, reduces costs.
The utility model comprises cylindrical shell, is arranged on the driving end spindle nose conjunction at cylindrical shell two ends; At uniform several " U " shape channel-section steels of described cylinder inboard wall, the openend of described each " U " shape channel-section steel respectively with cylinder inboard wall seal welding; At described each " U " shape channel-section steel, wherein electrothermal tube is set respectively the inside of one end, in described each electrothermal tube outer end, electrothermal tube guard shield is set respectively; At described each " U " shape channel-section steel, away from one end of electrothermal tube, capping is set respectively, at described capping arranged outside gland.
The utility model adopts φ 580 * 16mm thin-wall seamless steel pipe and the welding of " U " type channel-section steel, due to weight saving, reduces energy consumption and cost.The welding of " U " type of employing channel-section steel is especially without beating deep hole, and processing charges reduces greatly.The utility model, by the heat transfer of heating tube, makes the roll body hull-skin temperature temperature difference minimum, and surface temperature difference is no more than ± and 1 ℃, maximum temperature can reach 320 ℃.The utility model temperature is even, and while having load, two ends, also without the temperature difference, are better than steam and heat conduction oiling roller greatly, and energy-conserving and environment-protective.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises cylindrical shell 1, is arranged on the driving end spindle nose conjunction 2 at cylindrical shell 1 two ends; At 15 " U " shape channel-section steels 4 of cylindrical shell 1 inner wall even distribution, the openend of each " U " shape channel-section steel 4 welds with cylindrical shell 1 inner wall sealing respectively; At each " U " shape channel-section steel 4, wherein electrothermal tube 5 is set respectively the inside of one end, in each electrothermal tube 5 outer end, electrothermal tube guard shield 6 is set respectively; At each " U " shape channel-section steel 4, away from one end of electrothermal tube 5, capping 7 is set respectively, at capping 7 arranged outside glands 8.
