Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail:
Fig. 1 is the principle schematic of anti-explosion heating device;
Fig. 2 is the internal structure schematic diagram of the heat-generating pipe in Fig. 1.
Detailed description of the invention
Anti-explosion heating device as Figure 1-Figure 2, comprises drying baker 1 and the air heat case 2 that is arranged at drying baker 1 top.Drying baker 1 is for the resin being coated on Copper Foil 4 is dried, and air heat case 2 is for heating the air in drying baker 1.For making air carry out circulation between drying baker 1 and air heat case 2, the top of drying baker 1 is provided with the first air inlet 11 and first row air port 12, the top of air heat case 2 and bottom are respectively arranged with the second air inlet 21 and second row air port 22, second row air port 22 and the first air inlet 11 connect, between drying baker 1 and air heat case 2, be also provided with outer loop airduct, first row air port 12 is connected by outer loop airduct with the second air inlet 21, on outer loop airduct, be provided with circulating fan, thereby make air under the driving of circulating fan, circulate along following path: the second air inlet 21---inner chamber of air heat case 2---second row air port 22---the first air inlet 11---inner chamber of drying baker 1---second row air port 22---outer loop airduct---the second air inlet 21.Circulating fan is optional with power adjustable circulating fan, to can need or gas concentration situation is adjusted the air quantity of circulating fan in time according to technique.Because outer loop airduct and circulating fan all adopt technology of the prior art, those skilled in the art can correspondingly configure according to actual needs, is therefore not shown in the drawing.
The inner chamber of air heat case 2 is provided with some heat-generating pipes 3 that are direct rod shape, so that heat exchange occurs for the air of air heat case 2 inner chambers and heat-generating pipe 3.Heat-generating pipe 3 is preferably uniform setting, to improve the heat exchanger effectiveness of heat-generating pipe 3.Heat-generating pipe 3 is disposed with ceramic heating core body 31, metal ground loop 32, ceramic shading ring 33 and metal sealing pipe 34 from inside to outside.Ceramic heating core body 31 is the thermal source of heat-generating pipe 3.There is the accident of electric leakage for preventing 31 breakages of ceramic heating core body in metal ground loop 32.Pottery shading ring 33, for metal ground loop 32 and outermost metal sealing pipe 34 are separated by and are left, prevents that current delivery is to metal sealing pipe 34.The main effect of the outermost metal sealing pipe 34 of heat-generating pipe 3 is to make heat-generating pipe 3 integral sealings, prevent that the inflammable and explosive gaseous material giving out after resin is heated from directly contacting with the ceramic heating core body 31 in heat-generating pipe 3, avoids the generation of explosion accident.For strengthening the air of air heat case 2 inner chambers and the effect that heat-generating pipe 3 carries out heat exchange, on the outer wall of metal sealing pipe 34, radiating fin 35 can also be set.
Be banded structure owing to entering the Copper Foil 4 of drying in drying baker 1, for ease of realizing continuous production, drying baker 1 is arranged to rectangular-shaped, and the Copper Foil 4 that is coated with resin moves along the length direction of drying baker 1 at the inner chamber of drying baker 1.For this reason, feed well 13 and the blow tank 14 through drying baker 1 for banded Copper Foil 4 straight lines need be set on the two ends of the length direction of drying baker 1.For reducing the heat energy dissipation of drying baker 1, be preferably the centre position that the first air inlet 11 is arranged at drying baker 1 top, can reduce like this heat and discharge into the atmosphere from feed well 13 or blow tank 14, also be conducive to make the temperature in drying baker 1 even, reduce the temperature difference of drying baker 1 inner chamber simultaneously.Flow equably at the inner chamber of air heat case 2 for ease of air, reduce the temperature difference of drying baker 1 inner chamber, be preferably first row air port 12 and be set to two, and be symmetricly set in the both sides of the first air inlet 11, so that air that enter from the first air inlet 11 and after heating flows to the two ends of drying baker 1 length direction respectively from the centre position at drying baker 1 top.Owing to being provided with two first row air ports 12, correspondingly, outer loop airduct can be arranged to Y type, two first row air ports 12 is connected with the second air inlet 21, thereby makes to be configured between air heat case 2 and drying baker 1 two air circulation loops in parallel.
For preventing from being mingled with high temperature, the air of the inflammable and explosive gaseous material of high concentration continues heated under blast critical condition, the second air inlet 21 places are provided with the first gas concentration detector 23 and Temperature Detector 24, the first gas concentration detector 23 is connected with the electric-control system of anti-explosion heating device with Temperature Detector 24, in the time that the first gas concentration detector 23 detects that the content of material of contained setting is too high or when Temperature Detector 24 air themperature detected higher than setting value, the electric control system controls heat-generating pipe 3 of anti-explosion heating device stops heating, thereby can effectively avoid the generation of explosion accident.Simultaneously; 22 positions, second row air port are provided with Overtemp. protector 25; Overtemp. protector 25 is connected with the electric-control system of anti-explosion heating device; in the time that the air of air heat case 2 inner chambers is heated too high; Overtemp. protector 25 output signals, the electric control system controls heat-generating pipe 3 of anti-explosion heating device stops heating.Because the air that contains inflammable and explosive gaseous material is in the process of heating, the concentration of inflammable and explosive gaseous material can raise with temperature, for the generation of prevent exploding, the center of air heat case 2 inner chambers is also provided with the second gas concentration detector 26, monitors in real time the concentration of contained inflammable and explosive gaseous material in air heat case 2 inner chambers.
For gaseous matter corroding metal sealed tube 34 and air heat case 2 that the resin that prevents from being coated on Copper Foil 4 produces after heating, metal sealing pipe 34 is preferably and adopts stainless-steel pipe to make, and air heat case 2 is preferably by corrosion resistant plate and is welded.
The flammable explosive gas material producing after heating due to the resin being coated on Copper Foil 4 constantly circulates between air heat case 2 and drying baker 1, concentration reaches certain degree accident of easily blasting, for this reason, the top of drying baker 1 is also provided with explosion-proof pressure-reduction outlet 10, and explosion-proof pressure-reduction outlet 10 is directly connected with the outside atmosphere of anti-explosion heating device.For making the security of anti-explosion heating device higher, can also on explosion-proof pressure-reduction outlet 10, explosion-proof type air exhauster be installed, fast the high concentrations of gas in drying baker 1 is carried out to outer row.
Above embodiment is only not limited in order to the technical solution of the utility model to be described, does not allly depart from any amendment of the utility model spirit and scope or is equal to replacement, and it all should be encompassed in the scope of technical solutions of the utility model.
