Problems solved by technology

The problem it has is that it consumes a lot of power, and the hot air only circulates in one direction, making the heating uneven
[0005] Although the above scheme can improve the uniformity of furnace temperature, it is not practical and cannot really improve the quality of heat treatment.

Embodiment Construction

[0021] Such as figure 1 The aging furnace shown in the large air volume and strong air pressure hot air circulation mainly includes a furnace body 1, a furnace door 2 and its lifting mechanism 3, a heating device 4, a hot air circulation system, and an electrical control part. The hot air circulation system includes two centrifugal fans (5a , 5b), fan chamber and swing type wind deflector 6, the fan chamber is divided into upper and lower layers, i.e. the upper floor air chamber C and the lower floor air chamber; the adjustable opening and closing damper 8a and the opening and closing damper 8b are erected in the lower floor air chamber , the lower air chamber is divided into the left wind area B1, the middle wind area B2, and the right wind area B3. The middle wind area B2 is equipped with a swing-type wind deflector 6. The left wind area B1 and the right wind area B3 are symmetrical, and the left wind area Zone B1 and right wind zone B2 communicate with the furnace A; horizo...

Abstract

The invention provides an aging furnace with large air volume, strong air pressure and heated air circulation. A heated air circulating system comprises two centrifugal fans, a fan chamber and a swing-type air deflector, wherein the fan chamber is divided into an upper air chamber and a lower air chamber; the inside of the lower air chamber is vertically provided with two adjustable open / close airdoors so as to divide the lower air chamber into a left air area, an intermediate air area in which the swing-type air deflector is arranged, and a right air area; the inside of the upper air chamberopposite to the intermediate air area of the lower air chamber is provided with the two centrifugal fans of which the front parts and the back parts are distributed in parallel; the air inlets of thetwo centrifugal fans are opposite to each other and are communicated with the upper air chamber; the air outlets below the two centrifugal fans are communicated with the intermediate air area of thelower air chamber; and the adjustable open / close air doors are arranged between the upper air chamber and the left air area of and the right air area of the lower air chamber. The heated air with thelarge air volume and the strong air pressure flows circularly and sufficiently by the frequent direction changes of circulation, thereby ensuring the uniformity of the temperatures of each position inthe aging furnace, and improving the heat treatment quality of products.

Description

technical field [0001] The invention relates to an aging furnace for heat treatment, in particular to an aging furnace with a large air volume and strong wind pressure and hot air circulation, and belongs to the technical field of heat treatment equipment. Background technique [0002] The effect of the aging furnace used on the existing profile production line is to place the profile in the furnace, take it out and cool it after being heated by hot air, so as to enhance the mechanical properties of the profile. The basic structure of this aging furnace is to use electric heating and generate hot air through a heat exchanger, and the hot air circulates along the air duct in the furnace to heat the workpiece. The problem it has is that it consumes a lot of power, and the hot air only circulates in one direction, making the heating uneven. [0003] Patent 200620057404.5 discloses an aging furnace gas forced circulation reversing mechanism. The fan is installed in the aging fu...
