During operation, heat piece 7 and start, 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 pipe 12, make the cable dry with higher speed under heat piece 7's effect, simultaneously in-process drying to the lacquer layer, can produce organic gas, simultaneously gas is when exhausting, can carry a large amount of heats and spill over, thereby make heat piece 7 be in under the heating condition all the time, and then in the loss of the energy with higher speed, can shorten the life of heat piece 7, and at the in-process of drying, two kinds of circumstances can appear to the organic gas of production, one kind is in the numerical value of safe emission, another kind is the numerical value that exceeds safe emission.
When the content of the organic gas meets the emission value, the gas sensor on the valve regulator 2101 analyzes the gas components passing through the outlet pipe 12, when the emission standard is met, the valve regulator 2101 is opened by the control center, the gas directly enters the heat exchanger 41 through the hot gas discharge pipe 21, the heat contained in the gas is separated in the heat exchanger 41, the gas with less temperature components is discharged through the smoke discharge pipe 6, and meanwhile, the fan 42 carries heat and air to supplement the gas pressure in the furnace chamber 1101.
When the content of the organic gas does not meet the emission value, the gas sensor on the valve adjuster 2101 detects that the gas in the outlet pipe 12 does not meet the emission standard, and further the valve adjuster 2101 is maintained in a closed state, so that the gas in the outlet pipe 12 enters the combustion chamber 3102 in the combustion box 31 through the circulating pipe 22, and meanwhile, when the gas passes through the outlet end of the circulating pipe 22, the organic gas passing through the circulating pipe 22 is ignited through the igniter 3101, so that the gas is combusted in the combustion chamber 3102, and after the organic gas is combusted, the generated substances are water and carbon dioxide, which do not pollute the environment, and meanwhile, when the organic gas is combusted in the combustion chamber 3102, heat is generated in the combustion chamber 3102, the temperature in the furnace chamber 1101 and the combustion chamber 3102 is monitored through the temperature sensors fixed on two sides of the heat insulation plate 3103, and further, when the temperature in the combustion chamber 3102 is higher than the temperature in the furnace chamber 1101, at the moment, the two temperature sensors transmit the acquired data to the control center, and then send a working instruction through the control center, so that the upper plate of the heat insulation plate 3103 rotates, the heat insulation plate 3103 is opened, the heat in the combustion chamber 3102 is transmitted into the furnace chamber 1101 through the heat insulation plate 3103, the temperature in the furnace chamber 1101 is supplemented, and thus the heating pressure of the heating block 7 is reduced, and when the heat insulation plate 3103 is opened, the gas in the combustion chamber 3102 is preferentially introduced into the furnace chamber 1101 and does not flow into the gas outlet pipe 32, and the supplement of the gas pressure in the furnace chamber 1101 is met, so that the work of the fan 42 is not needed, and at the same time, after the gas enters the furnace chamber 1101, the step of the gas in the outlet pipe 12 is repeated; 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 any adjustment command to the control center, and the gas in the combustion chamber 3102 is exhausted through the 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 by the water absorbing plate 3201 firstly, 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 by the gas sensor on the sealing assembly 4301, so that when the gas sensor identifies that the gas components in the gas outlet pipe 32 meet the emission standard, the data is transmitted to the control center, and then the control center sends a regulation and control instruction to open the sealing assembly 4301, and further 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, after the heat exchange is completed, the waste gas is discharged through the smoke exhaust pipe 6, 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 as to realize the heat circulation; meanwhile, when the gas sensor identifies that the gas components in the gas outlet pipe 32 do not meet the emission standard, the sealing assembly 4301 is maintained 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 delivery pipe 5, the temperature in the furnace chamber 1101 is maintained, and meanwhile, the gas which does not meet the emission standard is further treated, so that the gas which does not meet the emission standard is subjected to harmless treatment while the heat is circularly supplemented.
Because the organic gas velocity and temperature generated by the cables with different compositions are different when the paint layer is dried, further, the moving speed of the cable in the wire slot 13 needs to be adjusted, and when the same cable is dried, the temperature in the oven cavity 1101 is always kept constant, in order to keep the drying efficiency of the cable in the wire slot 13 at a proper speed all the time, and further to control the moving speed of the cable and the content of the organic gas, that is, when the amount of organic gas burnt in the combustion chamber 3102 is large and the amount of heat generated is large by the high concentration of organic gas in the circulation pipe 22, and the heat insulating plate 3103 is opened, that is, when the temperature in the furnace chamber 1101 is constant, the moving speed of the cable in the wire chase 13 is relatively high, the concentration of the generated organic gas is relatively high, and at this time, the moving speed of the control cable is reduced, so that the content of the organic gas generated by the control cable is reduced; when the gas in the oven cavity 1101 is directly exhausted through the hot gas exhaust pipe 21, the generated amount of the organic gas generated in the oven cavity 1101 is smaller than the injection rate of the fresh air, which means that the moving speed of the cable is slow 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 organic gas passes through the circulation pipe 22 and the combustion amount of the organic gas in the combustion chamber 3102 is small, the insulation plate 3103 cannot be opened, 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 finished by the combustion assembly 3, that is, the moving rate of the cable in the wire chase 13 is the optimal rate under the condition that the temperature is kept constant.
