Description

Drying furnace

Technical Field

The utility model belongs to the field of plate and strip material color coating production devices, in particular to a drying furnace.

Background

At the board strip material color paint production line field paint solidification stage, the drying-oven is main curing equipment, the inside fixed flow distribution plate that all adopts of present drying-oven, through installation adjustment test, it is even only to guarantee each wind channel on fixed width, along with the development of technique, people's demand is not only limited to the slab band of one kind or several kinds of width, therefore, people set out the drying-oven of width broad, in order to adapt to the slab band of different width, and in the in-service use, when drying the narrower slab band of width, because the wind channel broad of drying-oven, the hot-blast both sides of slab band both sides are advanced along the both sides of slab band, can not directly blow on the slab band, thereby cause the waste of the energy.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a drying furnace to solve foretell technical problem.

One aspect of the present application is: a drying furnace comprises a drying furnace body, wherein an upper air duct and a lower air duct are arranged inside the drying furnace body, a space for accommodating a plate strip is arranged between the upper air duct and the lower air duct, an air outlet on the upper air duct is arranged downwards, an air outlet on the lower air duct is arranged upwards, air inlets of the upper air duct and the lower air duct are connected with hot air machines, guide rods are arranged in the upper air duct and the lower air duct respectively, connecting rods are uniformly arranged on the guide rods, and guide plates are arranged on the connecting rods; the guide rod extends out of the drying furnace body and is connected with a worm gear mechanism through a coupler, and the worm gear mechanism is connected with a servo motor.

Preferably, the upper air duct and the lower air duct comprise a primary air duct, a secondary air duct and a tertiary air duct which are sequentially arranged, the primary air duct, the secondary air duct and the tertiary air duct are arranged in rows and communicated, the guide plates are uniformly arranged in the first air duct and the third air duct, and the length of the second air duct is smaller than that of the first air duct and smaller than that of the third air duct.

The utility model provides a drying furnace has following advantage:

1. the guide rod is controlled to stretch and retract by the servo motor through the worm gear structure, and the angle of the guide plate in the air channel can be changed through the rotation of the guide rod and the connecting rod of the guide plate, so that the air speed of the air channel is changed.

2. Through the angle modulation to the guide plate for shunt when hot-blast through the guide plate, the degree of opening and shutting of guide plate influences hot-blast flow direction, thereby can obtain that people are required at certain hot-blast width and intensity, thereby can effectively control the wind channel and be adapted to the wide requirement of production line board.

Drawings

FIG. 1 is a schematic view of the overall structure of the drying oven of the present invention;

FIG. 2 is a schematic view of the internal structure of the drying oven of the present invention;

in the figure: the air heater comprises an air heater 1, a drying furnace body 2, an upper air duct 3, a lower air duct 4, a support 5, a tertiary air duct 6, a primary air duct 7, a secondary air duct 8, an air port 9, an air inlet 10, a guide plate 11, a connecting rod 12, a guide rod 13, a coupling 14, a worm gear mechanism 15 and a servo motor 16.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Embodiment 1, the utility model provides a drying oven, see fig. 1 and fig. 2, wherein the arrow direction indicates the hot-blast flow direction, including drying oven body 2, drying oven body is inside to be provided with upper air duct 3 and lower air duct 4, there is the space that is used for holding the slab band between upper air duct and the lower air duct, air outlet 9 on the upper air duct sets up downwards, air outlet 9 of lower air duct sets up upwards, air intake 10 of upper air duct and lower air duct is connected with air heater 1, be provided with guide arm 13 in upper air duct and the lower air duct all, evenly be provided with connecting rod 12 on the guide arm, install guide plate 11 on the connecting rod; the guide rod extends out of the drying furnace body and is connected with a worm gear mechanism 15 through a coupler 14, and the worm gear mechanism is connected with a servo motor 16. In this application, the worm gear mechanism can use current worm gear mechanism, for example worm gear speed reducer machine.

The drying furnace has the following advantages:

In embodiment 2, on the basis of embodiment 1, the applicant further designs that the upper duct and the lower duct include a primary duct 7, a secondary duct 8, and a tertiary duct 6, which are sequentially disposed, the primary duct, the secondary duct, and the tertiary duct are disposed in rows and are communicated, the guide plates are uniformly disposed in the first duct and the third duct, and the length of the second duct is smaller than the length of the first duct and smaller than the length of the third duct.

Foretell wind channel generally uses bellows to form, bellows passes through support 5 to be fixed to the drying furnace inner wall, satisfy the width of stoving steel sheet through tertiary oven, the first order oven is furnished with adjustable flow distribution plate, the second level oven is fixed bellows, the third level oven also is furnished with adjustable flow distribution plate, send into the oven through the fan when hot-blast, come with the degree of opening and shutting of third level flow distribution plate through adjusting first order flow distribution plate, adjust intensity and the width that hot-blast through the oven came out, adjusting range is bigger like this, and middle part also can not lead to hot-blastly not enough because of the drainage of drainage plate to both sides drainage often.

The above description is only for the preferred embodiment of the present invention and is not intended to limit the present invention, and the words first, second, etc. are used only for the distinction of names and not for the limitation of technical terms, and it is obvious to those skilled in the art that the present invention can be variously modified and changed.
