Abstract

PURPOSE:To heat-treat a large number of objects simultaneously and uniformly, thereby forming products of high quality without producing dispersion in the quality thereof, and to perform the treatment in a short time of period while preventing the influence of smog of solvent or the like, which is generated in the heat treatment. CONSTITUTION:Air of proper temperature is drawn from a heated air source 4 by a blower motor 3 controlled by a controller 5, which air is sent to a blowoff pipe 2 through a flexible hose 8 or the like, thereby blowing off the air from a blowoff port 6. The heated air blown off from the port 6 uniformizes the temperature of an object which is heated by far infrared rays or the like and also heats the object thoroughly.

2. Description of the Related Art As shown in FIG. 4, an electrothermal type heat treatment apparatus 21 using electric energy generally has a furnace chamber 22 for accommodating an object 11, an outer casing 23 surrounding it, and an outer casing 23. Electric heater 24 and fan 25 for blowing air
Etc. The air introduced into the outer casing 23 from the air intake port 26 of the outer casing 23 is heated by the electric heater 24 and becomes heated air of an appropriate temperature, so that the fan 25 causes the furnace chamber 2
Introduced in 2. The heated air introduced into the furnace chamber 22 comes into contact with the object 11, heats the object 11, circulates, and is partially discharged from the air outlet 27 to the outside of the housing 23. The electrothermal heat treatment apparatus 21 having the above structure has the following problems. That is, since the heated air does not uniformly contact the front and back of the object 11, the object 11 itself is unevenly heated. Therefore, a heating portion or a heating insufficient portion occurs, and the quality of the product deteriorates. Further, the air temperature in the furnace chamber 22 is not constant, and the object 11 near the inlet side of the furnace chamber 22 is well heated, but the object 11 at the outlet side or the corner is insufficiently heated, resulting in uneven products. . Further, since the heating is performed by the heat conduction method, it is necessary to heat the object in the furnace chamber 22 for a long time, which lowers the productivity.

As a heat treatment apparatus using far infrared rays, various characteristics, as shown in the known art,
Although it has advantages, it has the following problems.
First, when irradiation of far infrared rays is continued, the temperature of the object remarkably rises, and when the temperature exceeds a certain temperature, the structure of the object of the thermoplastic resin changes and the object is deformed. Moreover, since convection of air does not occur simply by irradiating the object with far infrared light, the object is not uniformly heated, resulting in uneven heat treatment. Furthermore, depending on the object, there is a solvent applied or containing a solvent, the solvent is evaporated by heating, the inside of the furnace becomes smog-like, this molecule itself absorbs far infrared rays, irradiation of far infrared rays There is a problem that interferes. In particular, when the object is a plastic product that needs to be annealed, the above-mentioned problems cause problems such as deterioration of product quality and increase in processing time. Note that the above-mentioned known technique does not solve these problems.

The object 11 is carried in outside the furnace body 10 (not shown).
A predetermined heat treatment is performed during transfer on the conveyor 12 which is mounted on the conveyor 12 and is transferred by driving the drive source 12 'and the chain 12 ".

FIG. 3 is a diagram for comparing the present invention with the prior art. In the figure, the line A shows the adjusted temperature of the object 11. When there is no air shower 1 and there is no control of far-infrared photothermal energy, for example, the photothermal energy is absorbed by the object 11 as indicated by a straight line B, the temperature of the object 11 rises, and the object 11 is softened beyond the limit temperature. Trouble such as causing it occurs. Therefore, the photothermal energy can be controlled so that the object temperature becomes equal to or lower than the limit temperature as shown by the straight line C. However, the object 11
Means that the temperature gradually rises while being conveyed in the furnace body 10 by the conveyor 12, and even if it is heated to a predetermined temperature just before being discharged from the furnace body 10, sufficient heat treatment is not applied to form a high quality product. I can't. On the other hand, air shower 1
3 can be used to cool the object 11 by injecting an appropriate amount of heated air having an appropriate temperature as shown by the straight line in FIG. 3, the object temperature can be controlled by the conveyor 1 as shown by the curve A in FIG.
2 can be kept almost constant over almost the entire area during the transfer.
Further, by using the air shower 1 together with infrared rays, 100% of the infrared ray characteristics are irradiated, and the entire surface of the object is evenly and uniformly heated. By the above, a uniform and high quality product can be produced.

The air shower described above can be applied to various heat treatment apparatuses, and the object 11 can be applied to various objects (plastic, glass, metal products, cloth, etc.). It is extremely effective when applied to the annealing treatment of objects. That is,
Although plastic products are molded, if they are used as they are, defects such as cracks due to stress relaxation and strength reduction occur due to external force due to impact, chemical stress and the like. When this plastic product is annealed, the molecules of the object are arranged and the above problems are eliminated. Also, ink,
Since many paints, adhesives, etc. have a solvent, the smog described above is likely to occur. Since the air shower diffuses smog and the like, the harmful effects of the smog can be eliminated.

According to the present invention, the following remarkable effects are obtained. 1) By using an air shower together with infrared rays, 100% of the infrared ray characteristics are irradiated, and the entire surface of the object is evenly heated. Therefore, a plurality of objects are uniformly processed. 2) The object is heated by the absorption of infrared light heat energy, but the object is heated by spraying an appropriate temperature air shower onto the object to uniformly heat the object to a predetermined temperature. As a result, it is possible to obtain a high-quality and consistent product. 3) Since the inside of the furnace is heated uniformly, the object is heated to an appropriate temperature in a relatively short time. Therefore, productivity can be improved. 4) When the object contains a solvent, etc., smog is generated by heating and interferes with the irradiation of infrared rays. However, by adopting an air shower, the smog is diffused and 100% of the characteristics that infrared light has photothermal energy Can be effectively irradiated. 5) Not only can it be applied to various heat treatments, but it can also be applied to heat treatments of plastics, glass, metal products, fabrics and the like. 6) In particular, it is suitable for annealing plastic molded products and forms uniform high quality products. 7) It has a relatively simple structure and can be easily implemented at low cost.
