Abstract
The utility model relates to a hot air drying device which comprises a box body, a base and a fabric conveying channel. A fan is arranged on the top of the box body. A heating device is arranged under the fan. An air suction channel is arranged between the fan and the heating device and a general channel is arranged on one side of the fan. One end of the general channel is communicated with the fan and multiple sub-channels are arranged at the other end of the general channel in a divided mode. Multiple through holes are arranged in the lower portions of the lateral walls of the sub-channels. The heating device is arranged above the fabric conveying channel. The air suction channel is in the shape of a reversed funnel and the end, adjacent to the heating device, of the air suction channel is provided with a large opening. The hot air drying device is mainly used for drying fabric which is printed and is small in size, rapid in temperature increase and high in heat recycling utilization rate.
Description
Technical field
The utility model relates to a kind of drying unit, in particular for the hot blast baking apparatus to drying through the fabric behind the stamp.
Background technology
In the stamp field, the general employing in the both sides that fabric moves through the position of drying unit is provided with the serpentine tube coil type heat exchanger that passes to steam, and calico is dried.Adopt this drying unit, it is low that fabric not only can not heat utilization efficiency, and fabric can't be realized omnibearing oven dry.
In the prior art, publication number is that the Chinese patent of CN 101871722 A has been announced a kind of heated-air circulation oven, is mainly used in the place that fire-proof board is dried.Heated-air circulation oven comprises casing, is provided with workpiece transport path in casing, and several heated air circulation devices.Although this invention has realized the recycling of heat owing to have heated air circulation device, the cyclic utilization rate of heat is low, and the programming rate of heater is slow.
Summary of the invention
The purpose of this utility model is to provide a kind of volume little, quick heating, the hot blast baking apparatus that the heat cyclic utilization rate is high.
The utility model relates to a kind of hot blast baking apparatus, comprise casing, base and fabric transfer passage, the top of casing is equiped with blower fan, the blower fan below is provided with heater, be provided with air-suction channel between blower fan and the heater, side at blower fan is provided with overall channel, one end of overall channel is communicated with blower fan, the other end is cut apart and is arranged to several subchannels, the lower sidewall of subchannel is provided with some through holes, described heater is located at fabric transfer passage top, described air-suction channel is inverted infundibulate, and air-suction channel is large near an end opening of heater.Compare with air-suction channel of the prior art, air intake device one end opening that the utility model will be provided with heater increases, heater is located at fabric transfer passage top, can absorption dehydration as much as possible after the hot-air that reduces of temperature, thereby improve the cyclic utilization rate of heat.
In order to change the flow direction of thermal current, improve drying efficiency, the side wall upper part of subchannel is downward-sloping.
Described heater is to be no less than 2 layers electric heating tube layer.Can make like this temperature of hot blast baking apparatus Air arrive fast predetermined numerical value.

Fig. 2 is the internal structure front view of the utility model when being used in combination;
Fig. 3 is the internal structure top view of the utility model when being used in combination.
The specific embodiment
Such as Fig. 1, Fig. 2, shown in Figure 3, a kind of hot blast baking apparatus, comprise casing 9, base 7 and fabric transfer passage 8, the top of casing 9 is equiped with blower fan 3, blower fan 3 belows are provided with heater 1, be provided with air-suction channel 2 between blower fan 3 and the heater 1, side at blower fan 3 is provided with overall channel 4, one end of overall channel 4 is communicated with blower fan 3, the other end is cut apart and is arranged to several subchannels 5, the lower sidewall of subchannel 5 is provided with some through holes 6, described heater 1 is located at fabric transfer passage 8 tops, and air-suction channel 2 is inverted infundibulate, and air-suction channel 2 is large near an end opening of heater 1.Wherein, the side wall upper part 10 of described subchannel 5 can arrange downward-sloping, and described heater 1 is preferably the electric heating tube layer that is no less than 2 layers.
Operation principle of the present utility model is: by the air of heater 1 heating casing 9 inside, by blower fan 3 hot-air is transferred to overall channel 4 from air-suction channel 2, blower fan more than 3 herein adopts centrifugal blower.At this moment, overall channel 4 is divided into several subchannels 5, uniformly with above the fabric 13 of transfer of heat in fabric Transfer pipe 8, that passes through fabric 13 stops and the impact of upstream heat air that hot-air is along fabric 13 upper surfaces to external diffusion to hot-air by through hole 6, meanwhile, the temperature of hot-air descends gradually, and is last under the effect of blower fan 3, is inhaled in the air-suction channel 2 by the slit between the subchannel 5, heat again, realize the recycling of heat.
In specific implementation process, the side wall upper part 10 of subchannel 5 can arrange downward-sloping, after hot-air enters subchannel 5, is subject to the stopping of side wall upper part 10 of subchannel 5, the direction of transfer of hot-air directly arrives fabric 13 surfaces through through hole 6 by original becoming forward downwards.
Such as Fig. 2, shown in Figure 3, in the course of the work, several hot blast baking apparatus often are combined into a drying room of printing machine 11 and use, and wherein, the overall channel 4 that adjacent two blower fans of the adjacent hot blast baking apparatus in a drying room of printing machine 11 connect is positioned at the opposition side of these adjacent two blower fans.The flow direction of hot-air in subchannel 5 is opposite in the adjacent hot blast baking apparatus, and during through the fabric 13 process drying room of printing machine 11 behind the stamp, the heat that fabric 13 every bits absorb equates that oven dry thoroughly.Drying room of printing machine 11 can move freely by the roller 12 that its bottom is provided with.
The hot blast baking apparatus that the utility model provides, volume is little, quick heating, the heat cyclic utilization rate is high, and, good drying effect.
