Abstract

The utility model relates to a building block-shaped continuous bridge type oven which belongs to the field of electric heating ovens. The utility model is characterized in that the existing straight-way type continuous oven is changed into the automatic closed bridge type oven. The oven body is composed of an inner and an outer layers which mutually insulate heat; flocculent heat-insulation material is filled in the middle. The connection part of the inner and the outer oven walls are added with a heat insulation pad and a heat insulation sleeve. The inner and the outer surface steel plates of the oven body are fixed on a skeleton by rivets, and thus, favorable heat insulation performance and sealing performance are formed; the conduction and convective heat loss is decreased. For convenient manufacture and installation, the utility model takes a building block-shaped structure and is firstly built in sections, and then the sections are connected into a whole. The utility model has the advantage of scientific connection method, and not only ensures heat insulation but also ensures seal.

Description

Block-style stoving box

The utility model belongs to electrical heating baking oven field.

Usually a large amount of at present baking ovens that use all are through types, though this baking oven structure packing list is connected easily with streamline, shortcoming is: 1. case mouth deflation is serious, and the thermal efficiency is low, and power consumption is big, the cost height; 2. upper and lower temperature difference is big in the case, the workpiece inequality of being heated, poor product quality; 3. cabinet insulation is poor, temperature height in the summer workshop; 4. pernicious gas is excessive serious, and smell is big, and workman's working condition is poor.

The purpose of this utility model provides a kind of baking oven of new-type structure, and it not only has the function of straight-through type oven but also can improve the quality of products, and improves workman's working condition, a large amount of saves energy.

The purpose of this utility model is achieved in that the bridge-type baking oven constitutes its improvement characteristics by casing, heating element heater, connecting gear and is: whole box body becomes bridge-type, the tank floor of neutral straight is higher than the open height that of both sides inclination casing, this is the natural enclosing effect that has utilized casing itself, thereby reduce case mouth deflation amount, reduce heat loss; In order to strengthen the sealing of casing self, fill cotton-shaped insulation material between the interior external box wall, the surface is coated with aluminium paint, and putty is filled in the slit; In order to stop the cold wind seepage loss, open the door at the bottom of changing the side door of former baking oven into case; Install for the ease of making, the utility model adopts building block type structure, the i.e. equal segmentation manufacturing of casing and frame; For reducing surface temperature, reduce heat loss, the metal that has cut off between the inside and outside wall connects.

Owing to adopt such scheme, compare with straight-through type oven, electric energy saving 50%, product quality improves, and the worker laboring environment improves.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the vertical section structural map of the continuous bridge-type baking oven of building block type.

Fig. 2 is the horizontal section structural map of the continuous bridge-type baking oven of building block type.

Fig. 3 is Fig. 2 node worker's a partial enlarged drawing.

Fig. 4 is the cutaway view of junction between case.

1. oblique case 2. straight case 3. frames 4. exhaust chimneys 5. external box walls 6. internal box walls 7. cotton-shaped insulation material 8. heat insulating washers 9. heat insulating mattress 10. end socket asbestos boards 11. inner contact plates 12. inside panels 13. exterior panels 14. lateral joint steel plates 15. electrical heating elements among the figure

In Fig. 1, straight case (2) selects right quantity to join together according to arts demand, is installed on the frame (3), and two ends connect oblique case (1) respectively, and exhaust chimney (4) is contained in straight case two, in establish air quantity and regulate flashboard.Electrical heating elements (15) is contained in straight case both sides.

Shown in Figure 2, internal box wall (6) is fixed in the external box wall (5), fills cotton-shaped insulation material (7) between the two, and tie point structure such as Fig. 3 are lined with heat insulating mattress (9) between inwall (6) and the outer wall (5), are with heat insulating washer (8) on the attachment bolt.

Junction structure such as Fig. 4 between case, when baking oven was made in segmentation, 10 centimeters spacing was left in the junction between case, and cotton-shaped insulation material (7) is filled in the mesozone in two end socket asbestos boards (10), has good heat-proof quality after the installation.Inwall adapter plate (11) docks with inside panel (12), and riveting is on the inwall skeleton, again lateral joint plate (14) is pressed in riveting jail on the exterior panel after filling the cotton-shaped insulation material of connector area (7), the slit filling, and the surface is coated with aluminium paint.

Claims
