The invention provides a heating device for composite corrugated paperboards. The heating device consists of an infrared-ray heating tube positioned on the inner part of the heating device, a heat insulating material arranged on the outer part of the infrared-ray heating tube, an outer cover on the outer part of the heat insulating material, and two reflecting plates at the two sides of the outer cover, wherein the heating device is mounted at a position 50-100m from composite corrugated body paper. The heating device is novel in design, not only can improve the quality of the composite corrugated paperboards, can save the energy consumption, can reduce the heating time, can improve the production efficiency, but also can reduce the production cost of a heating roller, can prolong the service life of the heating roller, and can increase the economic benefits of enterprises. The heating device is obvious in economic benefits and social benefits.
Description
Technical field
The present invention relates to a kind of corrugated board processing equipment, particularly a kind of combined corrugated board heater.
Background technology
In combined corrugated board is produced, first heated composite base paper by warm-up mill, body paper is softened, then under the effect of tractive force, enter in intermeshing Corrugator roller, cold solid becomes corrugation.And the character of cardboard depends mainly on the character of corrugation, so in composite corrugated combination board is produced, the heating effect of warm-up mill directly affects the quality of the composite corrugated combination board produced.
At present, the production of corrugated board adopts the heat transfer type of convect h mostly, and general heat medium has two classes: one is steam, and two is conduction oils.In convect h heat transfer, first want heat transfer medium, heat energy is delivered to roller surfaces by medium, to paperboard surface heating, and by the heat transfer of composite base paper self by the heat energy of absorption to body paper internal delivery, heat loss is serious.The heat transfer coefficient of combined corrugated board is less simultaneously, and diabatic process is slow.Because cardboard programming rate in heating process is slow, the temperature gradient inside and outside cardboard is comparatively large, and the quality of impact heating, causes the reduction of combined corrugated board quality.
Tradition corrugation hot-gluing machine group warm-up mill uses conduction oil as heat medium, the mode of electric heater for heating.In warm-up mill use procedure, there is many defects.Combination board needs warm-up mill long-term work in producing, so the conduction oil in warm-up mill is in high Warm status for a long time, easy coking causes the decline of heat conductivility; What the mode of heating of warm-up mill adopted is electric heater for heating, easily ties grease layer thermal resistance between electric heating tube tube wall and roller wall, causes that heat transfer rate is slow, the thermal efficiency is low; Heat-conducting oil heating is by electric heater for heating, indirect warm-up mill, in order to ensure the effect heated, needing to heat conduction oil to keep temperature always, causing amount of heat to lose; Electric heating tube in warm-up mill causes heating element overheats because of long-term heating, coking, and spoilage is high; In order to ensure the quality heated, conduction oil needs periodic replacement, this adds increased production cost, and pollutes; Warm-up mill adopts heat-conducting oil heating, adds the weight of warm-up mill self, in the manufacture of warm-up mill, certainly will cause the raising of warm-up mill cost.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of combined corrugated board heater, to improve the quality of combined corrugated board, save energy consumption and heat time, enhance productivity, reduce the production cost of warm-up mill simultaneously, improve the service life of warm-up mill, increase the economic benefit of enterprise.
The technical solution adopted in the present invention is: a kind of combined corrugated board heater, by the infrared ray heating tube being positioned at heater inside, the heat-barrier material of described infrared ray heating tube outside, the outer cover of described heat-barrier material outside and 2 reflecting plate compositions of outer cover both sides, described heater is arranged on apart from composite corrugated body paper 50 ~ 100mm position.
Far infrared heating technology utilizes radiation to heat, and the direct heating object of radiation is inner, does not need by any medium, decrease the loss in heat energy transmittance process, object can be made to be rapidly heated, and material surface and inside are heated simultaneously, ensure the uniformity of body surface and inner temperature.Avoid the heat loss that causes in convection heat transfer' heat-transfer by convection serious and because of the temperature gradient inside and outside combined corrugated board comparatively large, the quality of impact heating, causes the problem that combined corrugated board quality reduces.
Infrared radiation capacity usage ratio be inversely proportional to by the distance of heat hot thing, according to needs of production, infrared heating plate be arranged on distance calcium moulds body paper 50 ~ 100mm position.
Further, described infrared ray heating tube is halogen infrared ray heating tube.
Further, described heater is arranged in warm-up mill, traditional using conduction oil as heat medium to substitute, the warm-up mill of electric heater for heating.
Further, the length of described heater is 1000mm.
Compared with prior art, the invention has the beneficial effects as follows:
At the inner filling with insulation material of heating plate, can be good at the heat loss at heating plate back to drop to minimum, in radiator heating plate both sides, reflecting plate is installed, effectively can reduce and run off because reflecting the energy caused, heat be produced and maximizes;
Avoid the heat loss that causes in convection heat transfer' heat-transfer by convection serious and because of the temperature gradient inside and outside combined corrugated board comparatively large, the quality of impact heating, causes the problem that combined corrugated board quality reduces;
Infrared heating, generally can reduce by the heating-up time of 15% ~ 50%, improves 20% ~ 30% production efficiency, saves the energy ezpenditure of 30% ~ 50%, and can save other energy about 30%;
The present invention is novel in design, not only improves the quality of combined corrugated board, saves energy consumption and heat time, enhances productivity, also reduce the production cost of warm-up mill simultaneously, improves the service life of warm-up mill, increases the economic benefit of enterprise; This invention economic benefit and social benefit obvious.
