In order to realize the rapid drying of the cable in all directions, the position of the cable cannot deviate in the drying process, so that a wire groove 13 for restraining the position of the cable is arranged in the furnace chamber 1101, the wire groove 13 penetrates through the furnace chamber 11 along the height direction of the furnace chamber 11 and is communicated with the pipe cavity of the wire outlet pipe 12, namely, the position of the cable away from a heat source is restrained through the wire groove 13, so that the situation of uneven drying cannot be caused, meanwhile, in order to uniformly distribute heat in the heating process, a heating block 7 is fixedly arranged in the furnace chamber 1101, in this embodiment, the heating mode of the heating block 7 is preferably an electric heating mode, the wire groove 13 is annularly surrounded in the furnace chamber 1101, and then annular heating is realized in the wire groove 13 through annular arrangement, and the drying rate is improved.
Initially, the valve regulator 2101 is closed, the heat shield 3103 is closed, the closure assembly 4301 is closed, and the blower 42 is not in operation.
During operation, start heating block 7, and then promote the temperature in furnace chamber 1101, and then pass through wire casing 13 with the cable from the one end of keeping away from outlet tube 12 for the cable is dried under the effect of heating block 7 with higher speed, simultaneously at the in-process of drying to the paint layer, can produce organic gas, gaseous when the exhaust, can carry a large amount of heat and spill over simultaneously, thereby make heating block 7 be in heating state all the time, and then when accelerating the loss of the energy, can shorten heating block 7's life, and at the in-process of drying, two kinds of circumstances can appear in the organic gas that produces, one is in the numerical value of safe emission, the other is the numerical value that surpasses safe emission.
When the content of the organic gas accords with the emission value, the gas sensor on the valve regulator 2101 analyzes the gas components passing through the outlet pipe 12, when the content accords with the emission standard, the valve regulator 2101 is opened through the control center, so that the gas directly enters the heat exchanger 41 through the hot gas discharge pipeline 21, the heat contained in the gas is further separated in the heat exchanger 41, the gas with less temperature components is discharged through the smoke exhaust pipe 6, and meanwhile, the air carries heat and air through the fan 42 to supplement the gas pressure in the furnace chamber 1101.
When the content of the organic gas does not accord with the emission value, the gas sensor on the valve regulator 2101 detects that the gas in the outlet pipe 12 does not accord with the emission standard, and then the valve regulator 2101 is kept in a closed state, so that the gas in the outlet pipe 12 enters the combustion chamber 3102 in the combustion chamber 31 through the circulating pipe 22, simultaneously when the gas passes through the outlet end of the circulating pipe 22, the organic gas in the circulating pipe 22 is ignited by the igniter 3101, so that the gas burns in the combustion chamber 3102, and after the combustion of the organic gas, the generated substances are water and carbon dioxide, no pollution is caused to the environment, simultaneously when the organic gas burns in the combustion chamber 3102, heat is generated in the combustion chamber 3102, the temperature sensors fixed at two sides of the heat insulation plate 3103 monitor the temperature in the furnace chamber 1101 and the combustion chamber 3102, and when the temperature in the combustion chamber 3102 is higher than the temperature in the furnace chamber 1101, the two temperature sensors transmit acquired data to the control center, and then send working instructions through the control center, so that the heat insulation plate 3 rotates, and the heat is not required to be supplied to the furnace chamber 3103, and the temperature in the furnace chamber 3102 is not required to be supplemented by the furnace chamber 3102, and the pressure is not to be increased by the furnace chamber 3103, and the pressure in the furnace chamber 3102 is not required to be increased by the furnace chamber 3103, and the furnace chamber 3102 is cooled by the furnace chamber 3, and the pressure is not required to be cooled by the furnace chamber 3103, and the furnace chamber is opened, and the pressure is required to be cooled by the furnace chamber 2; when the temperature in the combustion chamber 3102 is less than or equal to the temperature in the furnace chamber 1101, the temperature sensor does not send an adjustment command to the control center at this time, and the gas in the combustion chamber 3102 is discharged through the gas outlet pipe 32.
When the gas in the combustion chamber 3102 passes through the gas outlet pipe 32, the water in the gas is absorbed through the water absorbing plate 3201, so that the water carried in the gas passing through the water absorbing plate 3201 is reduced, and then the gas components passing through the water absorbing plate 3201 are analyzed through the gas sensor on the sealing component 4301, so that when the gas sensor recognizes that the gas components in the gas outlet pipe 32 meet the emission standard, data are transmitted to the control center, and then the control center sends a regulating and controlling instruction to enable the sealing component 4301 to be opened, and then the gas passing through the gas outlet pipe 32 is sucked into the heat exchanger 41 through the rotation fan in the heat exchanger 41, the exhaust gas is discharged through the smoke exhaust pipe 6 after heat exchange is completed, and meanwhile, the heat stored in the heat exchanger 41 enters the furnace chamber 1101 through the fan 42 and the heat conveying pipe 5, so that heat circulation is realized; meanwhile, when the gas sensor recognizes that the gas composition in the gas outlet pipe 32 does not meet the emission standard, the sealing assembly 4301 is kept in a sealing state, so that the gas in the gas outlet pipe 32 is directly supplemented into the furnace chamber 1101 through the heat conveying pipe 5, the temperature in the furnace chamber 1101 is maintained, and meanwhile, the gas which does not meet the emission standard is further processed, so that the circulation supplement of heat is realized, and meanwhile, the gas which does not meet the emission standard is subjected to harmless treatment.
Since the organic gas rate and the temperature generated by the cables with different components are different when the paint layers are dried, the moving rate of the cables in the wire groove 13 needs to be adjusted, and when the cables with the same components are dried, the temperature in the furnace chamber 1101 is always kept constant, so that the drying efficiency of the cables in the wire groove 13 is always under a proper speed, and the moving speed of the cables and the content of the organic gas are controlled, namely, when the concentration of the organic gas in the circulating pipe 22 is higher, the combustion amount of the organic gas in the combustion chamber 3102 is larger, the generated heat is more, namely, when the heat insulation plate 3103 is opened, namely, the temperature in the furnace chamber 1101 is constant, the moving rate of the cables in the wire groove 13 is larger, the generated organic gas concentration is higher, and at the moment, the moving rate of the cables is controlled to be reduced, so that the content of the organic gas generated by the cables is controlled to be reduced; when the gas in the furnace chamber 1101 is directly discharged through the hot gas discharge pipe 21, the amount of organic gas generated in the furnace chamber 1101 is equal to less than the injection rate of fresh air, which means that the moving speed of the cable is slower and is not at the optimal drying rate, and the moving speed of the cable in the wire slot 13 is increased under the condition that the temperature is constant; when the amount of organic gas burned in the combustion chamber 3102 is small while the organic gas passes through the circulation pipe 22, the heat insulating plate 3103 cannot be opened at this time, and the gas passing through the gas outlet pipe 32 directly enters the heat exchanger 41, which means that the generation rate of the cable in the furnace chamber 1101 is just completed by the combustion assembly 3, that is, the moving rate of the cable in the wire groove 13 is the optimum rate while the temperature is kept unchanged.
