Description

Compound infrared drier

The utility model relates to a kind of compound infrared drier, belongs to " paper mould " goods rapid draing special equipment field.

The rapid draing of existing " paper mould " goods is provided with, and its dry employing fire coal or oil oven are thermal source, translate into hot blast through heat exchange, again goods are carried out heat drying by hot blast.The defective of this equipment mainly is: 1. fire coal is through heat exchanger, pipeline and go out hot blast, and its transfer process is long, and thermal conversion rate is low, and energy resource consumption is big; 2. heating space is big in the machine, and the complete machine thermal inertia is big, and technological temperature is wayward, and product quality is low; 3. mode of heating is a convection type, hot-air is delivered to heat on the surface of moulded paper pulp product, by the conduction of paper pulp heat itself the internal layer temperature is raise again, so not only efficient is low, and be higher than the internal layer temperature because of the paper pulp surface temperature, be unfavorable for internal moisture to external diffusion, thereby can produce quality problems such as wet in outer the doing, foaming, pin hole; 4. hot blast temperature is lower, and rate of drying is slow, can not adapt to industrial mass, quantity-produced requirement; 5. make thermal source with oil oven or fire coal, environmental pollution is serious.

The purpose of this utility model is to provide that a kind of energy consumption is low, thermal conversion rate is high, hot blast temperature is high, rate of drying is fast, good product quality, non-environmental-pollution be applicable to " moulded paper pulp product " quick-drying compound infrared drier.

The purpose of this utility model is to realize like this, a kind of compound infrared drier includes by housing and is arranged at stainless steel guipure, mesh-belt conveying mechanism, the electrical control cabinet that body, hot-air channel, dress paper pulp moulding product that the insulation material on the housing forms are used, it is characterized in that serve as reasons at least two composite drying sections of body and guipure form, before its each composite drying section is served as reasons mostly section be lifted on not a half section hot air convection baking zone composition that is connected with the hot-air channel of circulation of infrared radiation heating baking zone and back of the infrared electrical heating radiator at body top.

The compound infrared drier of said structure, because the thermal source of its thermal treatment zone adopts infrared electrical heating radiator, its electricity-thermal conversion rate height, and the electrical heating radiator is arranged at directly heating in the body, and thermal response is fast, so complete machine can shorten preheating time greatly, when for example adopting KSD-I type far-infrared electric heater, can shorten to 10-20 minute its preheating time by original 1-2 hour, and its energy consumption low only be the 1/3-1/4 of fire coal or fuel oil, so greatly reduce cost, do not have any environmental pollution; In addition, infrared electric heater, also because of its infrared energy, be directly passed to the pulp goods of being dried, can make its molecule generation resonance and be converted into molecular thermalmotion rapidly, dry from inside to outside internal stress, the convection stoving of the circulating air of its back segment in addition eliminated, make pulp product can not only reach the purpose of energy-conservation and flash baking, typing, and overcome quality problems such as wet in product distortion, pin hole, outer the doing.

Advantage of the present utility model is: energy resource consumption is little, and drying rate is fast, and the product quality height can adapt to industrial mass, produce continuously, the production efficiency height, and non-environmental-pollution can effectively improve workman's operating environment.

With drawings and Examples structure of the present utility model is done further narration below

Fig. 1 is the overall structure schematic diagram of the utility model embodiment;

Fig. 2 is the A-A cutaway view of Fig. 1;

Fig. 3 is the B-B cutaway view of Fig. 1;

Fig. 4 is the stainless steel extra wide type (〉=1.0M) structural representation of the flat conveying orientation mechanism of guipure;

Fig. 5 is the roller distribution schematic diagram of the guiding mechanism of Fig. 4.

By shown in Fig. 1-3 as seen, the compound infrared drier of present embodiment is for being made up of body 1, the institutes such as the infrared electric heater 2 of wide range, hot air circulation passage 5, stainless steel guipure 4, mesh-belt conveying mechanism 6 and electrical control cabinet (not shown) that are located on the body 1.Electrical control cabinet triggers (switch) circuit by control circuit and controllable silicon, can control the speed of service of buncher of wired belt conveyer structure and the power output of control wide range infrared ray electric heater.Body 1 is by being made up of frame 13, housing 11 and the adiabator layer 12 be located on the housing.

On body 1 and guipure 4, be provided with a plurality of composite drying sections, preceding most sections of its each composite drying section is the infrared radiation heating baking zone, its infrared electrical heating radiator 2 that is lifted on body 1 top serve as reasons the infrared electric heater 21 of horizontal wide range and longitudinally the infrared electric heater 22 of wide range form, and, can select SKI for use in order to strengthen electricity-Re transition heat efficient)-the infrared electric heater of I type.Thereafter not a half section is the hot air convection baking zone, the hot-air channel 5 of its circulation is by being made up of the air draught air channel 51 and the supply air duct 52 of negative pressure heat absorption wind, wherein air draught air channel 51 is by being made up of air exhauster 513, inlet scoop 511, wind pumping channle 512, supply air duct 52 by by hair-dryer 523, air delivery duct 522, be arranged at the upper and lower upper and lower air-supply by-

path

5221,5222 of stainless steel guipure in the body and export the hot blast import 521 that is connected and formed with air exhauster 513.Because recycling of hot blast makes full use of waste heat energy, saved energy consumption.The setting of the upper and lower air-supply by-path in above-mentioned this air channel can make each online " paper pulp mold " product can realize uniform convection stoving, to guarantee product quality.

For make width the extra wide type stainless steel guipure more than 1 meter in conveying steadily, do not swing, we are provided with a mesh-belt conveying guiding mechanism 7 on frame 13, by visible guiding mechanism 7 shown in Figure 4 serve as reasons a plurality of supports 74 of evenly being arranged at frame 13 both sides, the axle bed 71 of the tape spool 72 that is connected with each support and be sheathed on each roller 73 on 72 and formed, and the place is provided with groove 731 in the middle of each roller, and the guipure both sides are arranged at respectively in these grooves.When mesh-belt conveying, it slides away along the groove of both sides, thereby makes its left and right deviation not under the effect of this guiding mechanism, can carry reposefully.

Owing to dry the product difference aborning, requirement drying time difference, the moisture content of its release is also different, in the present embodiment, available buncher is as the engine of the conveying mechanism of stainless steel guipure, regulate the rotating speed of buncher 61 with the switch board control circuit, just can realize requirement the different drying times of product; In order to guarantee the quality of product, must control temperature, the humidity of baking zone, in the present embodiment, the adjustable air-valve of one open degree 3 is set on wind pumping channle 512, control its humidity with this, and the switching time of adopting the control circuit of controlling silicon controlled conducting angle to control infrared electric heater is controlled temperature.
