The heated-air circulation device comprises a fan, the air inlet of the fan is provided with an induced draft path in which a heating device is arranged, and the air outlet of the fan is provided with a total path of which the tail end is provided with two branch paths; the branch path is provided with an upper path and a lower path, wherein the upper path and the lower path are respectively arranged on the upper side and the lower side of the workpiece delivery path, the side plates of the upper path and the lower path, which approach to the workpiece delivery path, are respectively provided with a plurality of through holes. The invention is suitable for occasions in which fire-proof plates are dried.
Description
Technical field
The present invention relates to the heated-air circulation oven that a kind of PLASTIC LAMINATED panel production line is used.
Background technology
Baking oven commonly used at present generally is installed in blower fan on the sidewall of baking oven, the heat that external heat source is sent by blower fan work is passed in the casing, dry sheet material in the baking oven with this, the working method of this inside and outside cycle heat exchange heating has greatly been wasted rate of energy, and sheet material also can't be fully, oven dry in all directions.
Summary of the invention
Technical problem to be solved by this invention is: a kind of heat utilization ratio height, dry heated-air circulation oven fully will be provided.
For addressing the above problem, the technical solution used in the present invention is: a kind of heated-air circulation oven, comprise casing, in casing, be provided with workpiece transport path, in casing, be provided with several heated air circulation devices, the structure of described heated air circulation device is: comprise blower fan, air intake vent at blower fan is provided with air-suction channel, in air-suction channel, be provided with heater, air outlet at blower fan is provided with overall channel, end at overall channel is provided with two subchannels, described subchannel is provided with upper channel and lower channel, described upper channel and lower channel lay respectively at workpiece transport path on, following both sides are respectively arranged with several through holes on the upper channel of close workpiece transport path and the side plate of lower channel.
Be provided with flow distribution plate in described overall channel and the subchannel respectively;
All be the uneven shape that height rises and falls near the upper channel of workpiece transport path and the side plate of lower channel.
The invention has the beneficial effects as follows: the air circulation in the baking oven is added heat utilization, improved rate of energy greatly, through hole is set on the side plate near the upper channel of workpiece transport path and lower channel can omnibearingly dry sheet material.

The specific embodiment
Below in conjunction with accompanying drawing, the structure and the operation principle of heated-air circulation oven of the present invention is described in further detail.
As shown in Figure 1 and Figure 2, a kind of heated-air circulation oven comprises casing 1, is provided with workpiece transport path 2 in casing 1, is provided with several heated air circulation devices in casing 1, and its concrete quantity can be determined according to the length of casing.The structure of described heated air circulation device is: comprise blower fan 3, air intake vent at blower fan 3 is provided with air-suction channel 4, in air-suction channel 4, be provided with heater 5, air outlet at blower fan 3 is provided with overall channel 6, end at overall channel 6 is provided with two subchannels 7, and its concrete quantity also can be determined according to the size of casing 1 and the power of blower fan 3.On described subchannel 7, be respectively arranged with upper channel 8 and lower channel 9, described upper channel 8 and lower channel 9 lay respectively at the upper and lower both sides of workpiece transport path 2, the lower side panel 101 of the lower channel 9 of the epipleural 10 of the upper channel 8 of close workpiece transport path 2 and close workpiece transport path 2 all is not flat-shaped that height rises and falls, and is respectively arranged with several through holes 11 and through hole 111 on epipleural 10 and the lower side panel 101.Be respectively arranged with a flow distribution plate 12 and a flow distribution plate 121 in described overall channel 6 and the subchannel 7.
Operation principle of the present invention is: when workpiece from workpiece transport path 2 through out-of-date, blower fan 3 is started working, air in the casing 1 is inhaled into air-suction channel 4 under the suction of blower fan 3,5 pairs of air of heater heat, air after the heating is transported to overall channel 6 by blower fan 3, shunting enters subchannel 7 then, entered upper channel 8 and lower channel 9 by shunting again, because epipleural 10 and lower side panel 101 height rise and fall uneven, so also dispersion shape ground is towards all angles for the through hole 11 that is provided with and the direction of through hole 111, the air after the heating just can heat workpiece from different perspectives by through hole 11 and through hole 111 like this, oven dry.In order to guarantee to dry workpiece evenly, fully, can regulate the angle of a flow distribution plate 12 and a flow distribution plate 121, make that the air mass flow that finally enters upper channel 8 and lower channel 9 is suitable.Air from through hole 11 and through hole 111 ejections is sucked air-suction channel 4 by blower fan 3 more simultaneously, so repeatedly workpiece is heated, dries.
Advantage of the present invention be: the energy utilization rate height, to the oven dry of sheet material fully, comprehensively.
