Abstract
The utility model belongs to the technical field of tunnel furnaces, particularly discloses a tunnel furnace which is used for material manufacturing, chemical engineering, food and other industries and for heating objects. The main structure of the tunnel furnace is a tubular furnace body which is divided into a feeding section, a heating section and a discharge section; in the furnace body, the heating section is provided with a heating element and material conveying mechanisms which are arranged on both ends of the heating section and comprise rollers, transmission wheels and conveyer belts; a feed opening and a discharge port are arranged on both ends of the tubular furnace body; the middle part of the tubular furnace body is provided with a vent hole; in the tubular furnace body, the feeding section, the heating section and the discharge section form an arch-shaped structure in which the heating section is higher than the feeding section and the discharge section; and the upper edges of the feed opening and the discharge port are lower than the height of the inner wall of the furnace body in the heating section. The tunnel furnace greatly reduces the air convection between the high-temperature environment in a heating area and the external normal temperature environment and improves the heat retention capability in the heating section, and the energy-saving effect reaches above 30 percent.
Description
Technical field
The utility model belongs to the continuous tunnel furnace technical field, relates to industries such as a kind of material manufacturing, chemical industry, food, with object-heating tunnel furnace.
Background technology
The employed continuous tunnel furnaces of industry such as material manufacturing at present, chemical industry, food, its structure is as shown in Figure 1: comprise tunnel body of heater 2 that is provided with heating element heater 1 and the material transport mechanism that is made of drive 3 and conveyer belt 4, this body of heater is the straight barrel type structure, promptly constitutes cylindrical structure body of heater charging aperture 5, heating region 6 and discharging opening 7 and is horizontal structure; The continuous tunnel furnace of this structure in use heating region, charging aperture and discharging opening convection current can inevitably occur owing to temperature difference, thereby causes the heat energy of heating region to scatter and disappear from charging aperture and discharging opening, causes the efficiency of body of heater to descend; Secondly, this continuous tunnel furnace passes through the exhaust outlet 8 of setting and upper of furnace body directly with exhaust gas evacuation, thereby causes forming temperature difference convection current between exhaust outlet and charging aperture and the discharging opening, causes the heat energy emptying; Therefore the continuous tunnel furnace of this structure exists great thermal waste in use.
The utility model content
First purpose of the present utility model just provides the high continuous tunnel furnace of a kind of heat energy utilization rate.
Realize that the technical scheme that the utility model purpose is adopted is:
A kind of continuous tunnel furnace, comprise cartridge type body of heater that is provided with heating element heater and the material transport mechanism that constitutes by drive and conveyer belt, the two ends of described cartridge type body of heater are respectively charging aperture and discharging opening, be provided with steam vent in described cartridge type upper of furnace body, described cartridge type body of heater is divided into feed zone, bringing-up section and discharging section, forms the domes that bringing-up section is higher than feed zone and discharging section; Be provided with the running roller mechanism that constitutes the material transport mechanism conveyer belt at described bringing-up section two ends.
Its additional technical feature is:
---the upper edge of described charging aperture and discharging opening is lower than the height of inboard wall of furnace body in the described bringing-up section;
---described charging aperture, discharging oral area are provided with the bending hot baffle;
---described steam vent is connected with air inlet by pipeline, and the air outlet of described blower fan is communicated with described feed zone and discharging section by utilidor;
---be connected with the high-temperature gas processing mechanism between described steam vent and the air inlet.
Continuous tunnel furnace provided by the utility model is compared with prior art and is had the following advantages: one, because continuous tunnel furnace has adopted domes, significantly reduce the cross-ventilation of interior hot environment of heating region and outside normal temperature environment, improved the heat energy hold facility in the bringing-up section.The second owing to adopted high temperature hot gas recycle and reuse device, with the high temperature hot gas that reclaims after treatment, be transported to body of heater inside more again, thereby further increased body of heater inside the heat energy hold facility, improved the temperature of charging and discharging mouths.Because the improvement of this continuous tunnel furnace structure, reach more than 30% with the present structure energy-saving effect that compares.
Description of drawings
Fig. 1 is the structural representation of continuous tunnel furnace in the prior art;
The structural representation of the continuous tunnel furnace that Fig. 2 provides for the utility model.
The specific embodiment
Be described in further detail below in conjunction with the structure of accompanying drawing the continuous tunnel furnace that the utility model proposed.
Be illustrated in figure 2 as the structural representation of the continuous tunnel furnace that the utility model provides, the structure that promptly constitutes this continuous tunnel furnace comprises: be divided into feed zone 9, the cartridge type body of heater of bringing-up section 10 and discharging section 11, in body of heater, bringing-up section is provided with heating element heater 1 and by the running roller 12 that is arranged at the bringing-up section both ends, the material transport mechanism that drive 3 and conveyer belt 4 constitute, charging aperture 5 and discharging opening 7 are arranged at the two ends of cartridge type body of heater, the cartridge type upper of furnace body is provided with steam vent 8, feed zone in above-mentioned cartridge type furnace binding, bringing-up section and discharging section form bringing-up section and are higher than the domes of feed zone and discharging section, and make the upper edge 13 of charging aperture and discharging opening be lower than the height of inboard wall of furnace body 14 in the bringing-up section.
Use the continuous tunnel furnace of this structure, owing to formed the domes that bringing-up section is higher than feed zone and discharging section in the cartridge type body of heater, and the upper edge of charging aperture and discharging opening is lower than the height of inboard wall of furnace body in the bringing-up section, therefore charging aperture and the discharging opening convection current of the discharging section amount that shed of the heat in the bringing-up section by feed zone is very little, has improved the efficiency of body of heater.
Heat scatters and disappears by the convection current of charging aperture and discharging opening in the body of heater in order further to reduce, and is provided with bending hot baffle 15 at charging aperture, discharging oral area.
In order further to improve the thermal efficiency of this continuous tunnel furnace, steam vent 8 is connected with the mechanism 17 that is used for high temperature gas cleaning, dehumidifying, blower fan 18 air inlets successively by pipeline 16, be communicated with the feed zone and the discharging section of body of heater by utilidor 19 by the air outlet of blower fan again after the high-temperature gas passes of in the body of heater of associating, the drawing dehumidifying, high temperature hot gas is sent in the body of heater once more.
