Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail. Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
As Figure 1-3, the radiant type Heating air box of the present invention includes longitudinal extension and the radiant chamber 1 being made up of the metallic plate of good heat dissipation effect, be fixedly installed on that radiant chamber is internal and both lateral sides fix with radiant chamber inwall is connected, the dividing plate 11 of longitudinal two ends and radiant chamber sidewall maintenance spacing, multiple are arranged in described radiant chamber and are arranged in the homogenizing plate 12 above described dividing plate at interval in the upper and lower, described dividing plate with constitute the air intake passage and return air channel that connect with air inlet 13 and air outlet 14 respectively between the base plate of radiant chamber. In general, described radiant chamber is cuboid, and described dividing plate and homogenizing plate horizontal parallel are arranged.
The Heating air box monoblock type of the present invention is strong, the dividing plate adopting bottom carries out interval division, then the homogenizing plate utilizing top carries out current-sharing, the uniform of thermal current can be accomplished in the height direction, improve the thermal uniformity of Heating air box as far as possible, and heat radiation type is heated, avoid circulated air directly and absorption surface, ensure the high-cleanness, high requirement of workpiece, can effectively meet low-temperature bake use in industry, such as the drying section of white car.
Specifically, described homogenizing plate is monoblock type or discontinuous design, i.e. its both lateral sides is fixing with the inwall of radiant chamber to be connected, can by an entire plate as a homogenizing plate, or multiple end plate intervals arrange one horizontal intermittent type homogenizing plate of composition, so all can realize the current-sharing purpose of the present invention, it is preferable that, described homogenizing plate length is incremented by from the bottom to top, namely constitute inverted triangle form, so can guarantee that the ventilation at top, it is achieved uniform heat radiates.
As Figure 1-5, the baking room of the present invention includes the drying chamber 2 being made up of heat-insulating wall of longitudinal extension, it is arranged in drying chamber and material delivery track 21 placed in the middle longitudinal extension, multiple time intervals it is arranged in drying chamber and lives apart in the bearing 22 of material delivery track both sides, and two are correspondingly arranged at radiant type Heating air box 1 described on described bearing. That is, multiple bearings are two Column Layouts. One of them described bearing is fixing with the bottom of radiant chamber to be connected, and remaining holder top is rotatably provided the load roller 3 carried bottom described radiant chamber. Preferably, fixing with bearing and be connected in the middle part of described radiant chamber, the air inlet of described radiant chamber and return air inlet are arranged on the fixing point both sides with bearing. Described load roller is the steel pipe that two ends are confined on bearing by three baffle plates, being provided with the support plate corresponding with carrying roller bottom described radiant chamber and contact stationarity to improve, three baffle plates lay respectively at the front portion of steel tube end part, rear portion and outside fixing with holder top and are connected.
Heating air box is equivalent to an inside and is full of the chest of hot-air, whole Heating air box is placed on the bearing in the chamber body of drying chamber, holder top is the load roller that can roll, such as steel pipe, Heating air box temperature can occur line to expand after raising, it is welded and fixed with bearing in the middle part of Heating air box, both sides utilize load roller to realize slidably, efficiently solve radiant chamber sliding problem, and ensure that radiant chamber will not fall from bearing slip up when expanding and sliding, fixing point is selected in the middle place near inlet and outlet simultaneously, effectively prevent swell increment from excessively concentrating and drawing crack in/out air tube.
Further, for improving the heats of bottom, when drying such as white car, chassis place thickness is generally relatively larger, for improving the drying effect of this kind of similar operating mode, described radiant chamber bottom inside is formed with auxiliary chamber 15 with protruding inwardly from, and described two ends, auxiliary chamber connect with described air intake passage and return air channel, and the upper surface in described auxiliary chamber is inclined-plane. That is, utilize auxiliary chamber to constitute a gas channel being positioned at bottom and inside, it is provided that the extra heating of keypoint part, improve overall drying effect.
Wherein, topple for preventing from also including Heating air box, its line turgor movement is guided, the sidewall also including multiple with described drying chamber fixes the side registration arm 5 being connected, described registration arm end is formed with the stopper slot 51 of under shed, is formed at described radiant chamber top and can mate the guiding gusset 16 embedding in described stopper slot and can longitudinally moving forward and backward. Utilization guiding gusset coordinates with stopper slot, can be effectively improved stability in the large, it is prevented that swinging of Heating air box occurs.
Because radiation bellows are placed in drying chamber body, for preventing radiation bellows top dust stratification, the lower bayonet slot of longitudinal extension it is formed with inside described radiant chamber cover top surface, top board at described drying chamber is provided with the upper draw-in groove corresponding up and down with described lower bayonet slot, is provided with shrouding 6 between described lower bayonet slot and upper draw-in groove. Utilize shrouding by internal with drying chamber for radiation bellows top cutting, effectively prevent radiation bellows top dirt accumulation, and only shrouding inner surface need to be cleaned or unpick and wash when needing to clear up, reduce labor intensity, and card slot type design, line will not be expanded into impact.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the principles of the invention; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
