Abstract
The utility model relates to a gas flow curing oven, which is used for the field of metal coating and comprises an oven body. Electric heating tubes are arranged on the inner wall of the oven body, a bottom plate of the oven body and the lower edge of the peripheral wall of the oven body form a cavity on the lower side of the oven body, a fan is disposed in the cavity, an air outlet of the fan upwardly extends into the oven body via more than two gas pipes, and the gas pipes are peripherally and uniformly distributed around the oven body. The curing oven can solve the problem of sinking of liquid coating under the effect of gravity, so that uniformity of coating on the surface of a workpiece is further improved, coating curing efficiency is enhanced to a great extent.
Description
Technical field
The utility model relates to the coated metal production equipment, especially, relates to the curing oven equipment in a kind of coated metal field.
Background technology
For hardware, under more situation, need carry out application to its surface, so that metal component surface has good antiseptic property, and make it more neat and artistic.For this reason; Usually adopt simple manual work to spray paint or the mode of electrostatic spraying; When adopting simple and easy manual work to spray paint,, therefore make surface of the work that the uneven situation of paint trickling takes place easily because the ejection of common spray gun is liquid paint; Finally cause coating fruit after the uneven thickness everywhere, coating quality is relatively poor.
In view of the foregoing; In the coated metal technology of present high requirement; Require to adopt the electrostatic spraying mode to carry out application, promptly adopt electrostatic gun that pulverous charged coating particles is sprayed to charged workpiece, make coating particles be adsorbed in surface of the work equably; Through high temperature melting, levelling, curing process, make coating be coated on surface of the work equably again.
For above-mentioned coating fusing, levelling, curing process; Usually in sintering oven, carry out, and in the coating fusion process, because the coating after the fusing has gravity; Under nature, the trend that flows downward will be arranged; If do not take measures, then the coating density of workpiece below will be greater than the density of workpiece top, and this makes coating quality receive bigger limitation; In addition, generally only take radiation heating equipment at present, the coating curing efficiency of surface of the work also limits to some extent.
Summary of the invention
In order to address the above problem; The purpose of the utility model is to provide a kind of air-flow curing oven; This curing oven not only can solve the sinking problem of liquid coating under the gravity effect, with the coating uniformity of further raising surface of the work, and can improve the curing efficiency of coating to a great extent.
The utility model solves the technical scheme that its technical problem adopted: this air-flow curing oven comprises body of heater; The inwall of said body of heater is provided with electrothermal tube; The lower edge of the base plate of this body of heater and body of heater perisporium forms a cavity below body of heater; Be provided with blower fan in this cavity, it is inner that the air outlet of said blower fan extends upwardly into said body of heater through two above tracheaes, and circumferentially be uniformly distributed with around body of heater.
As preferably, said tracheae is provided with 4-6.
As preferably, said tracheae is made up of thermal conductive metal pipe, and its part that stretches in the body of heater is processed black, helps absorbing radiations heat energy, makes tracheae keep warm attitude, offers warm of ascending air.
As preferably, said electrothermal tube is the ring light wave duct that is provided with around said inboard wall of furnace body, and it has more than one, along body of heater short transverse equidistant placement.
As preferably, said inboard wall of furnace body is provided with specular layer, and strengthening thermal-radiating reflection, most of heat energy that said electrothermal tube is produced is all absorbed by surface of the work.
The beneficial effect of the utility model is: this air-flow curing oven is positioned over the workpiece that adsorbs coating powder in the stove in use, connects electrothermal tube; Utilize heat radiation to workpiece surface coating melt, levelling, cured, and start said blower fan simultaneously, make the blower fan delivery air that makes progress; This air-flow slowly rises around workpiece; With the gravity effect of the liquid coating after the balance fusing, thereby make coating more even, in addition; Owing to the effect of brushing of air-flow, can further accelerate the paint solidification efficient of surface of the work.
Description of drawings
Fig. 1 is the vertical profile sketch map of an embodiment of the utility model air-flow curing oven;
Fig. 2 is the vertical view of Fig. 1 embodiment.
Among the figure: 1, body of heater; 11, base plate; 2, electrothermal tube; 3, blower fan; 31, tracheae.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
In Fig. 1, embodiment shown in Figure 2, this air-flow curing oven comprises body of heater 1, and the inwall of said body of heater 1 is provided with electrothermal tube 2; Said electrothermal tube 2 is the ring light wave duct, has a plurality ofly, equidistantly arranges along the short transverse of body of heater 1; The base plate 11 of said body of heater 1 forms a cavity with the lower edge of body of heater 1 perisporium below body of heater 1; Be provided with blower fan 3 in this cavity, the air outlet of said blower fan 3 extends upwardly into said body of heater 1 inside through four tracheaes 31, and circumferentially is uniformly distributed with around body of heater 1.
Above-mentioned air-flow curing oven, said tracheae 31 are made up of thermal conductive metal pipe, and like copper pipe, aluminum pipe, its part that stretches in the body of heater 1 is processed black, helps absorbing radiations heat energy, makes tracheae 31 keep warm attitude, offers warm of ascending air.
Above-mentioned air-flow curing oven, said body of heater 1 inwall is provided with specular layer, to strengthen thermal-radiating reflection, most of heat energy of said electrothermal tube 2 generations is all absorbed by surface of the work.
The said flow curing oven is positioned over the workpiece that adsorbs coating powder in the stove in use, connects electrothermal tube 2; Utilize heat radiation to workpiece surface coating melt, levelling, cured, and start said blower fan 3 simultaneously, make upwards delivery air of blower fan 3; This air-flow slowly rises around workpiece, with the gravity effect of the liquid coating after the balance fusing, thereby makes coating more even; In addition, owing to the effect of brushing of air-flow, can further accelerate the paint solidification efficient of surface of the work.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
