Background

The purpose of the dryer is mainly to ventilate and heat the spinning raw material slices, hot air is used for heating the spinning raw materials to achieve the drying effect, and the condition of the final drying effect directly influences the state of spinning production. The heater in the existing dryer mostly adopts simple electric heating or simple heat-conducting medium heating. The electric heating energy consumption is higher, and the heat conducting medium heating is realized by utilizing the existing boiler in the production area to provide heat energy, so that the energy consumption is greatly reduced compared with the electric heating energy consumption. However, although the heating of the heat-conducting medium is energy-saving, when the boiler in the production area is in a fault shutdown state, the dryer does not have a heating source, so that the spinning is stopped, and greater economic loss is caused.

Detailed Description
The technical scheme of the utility model is further explained by combining the attached drawings.
As shown in fig. 1 and 2, the drying energy-saving heater comprises a housing 1, an electric heating mechanism 2, an inner gas pipe 3, a heat-conducting medium partition plate 4, a heat-conducting medium outlet 5, a heat-conducting medium inlet 6, a heat-conducting medium inlet control valve 7, a temperature sensor 8, a temperature control meter 9 and a control line 10.
The first heating method of the heat-conducting medium is as follows: the heat conducting oil produced by the boiler is used for heating. The heat conducting oil flows out through the heat conducting medium inlet 6 and then through the heat conducting medium outlet 5, so that the cold air in the inner air pipe 3 exchanges heat through the heat conducting oil, and the cold air in the inner air pipe 3 is changed into hot air to be supplied to the next working procedure for use. Wherein, in order to prevent the heat conducting oil from entering the inner air pipe 3, the heat conducting medium baffle plates 4 are added around the inner air pipe 3, so that the inner air pipe 3 is completely isolated from the outside. Because the cold air needs the heat transfer to the technology settlement temperature after the heat transfer of inner trachea 3, add temperature sensor 8 outside the export of inner trachea 3 and carry out actual measurement temperature. The process temperature is set on the temperature control meter 9, when the actually measured temperature of the temperature sensor 8 is higher than the process set temperature on the temperature control meter 9, the temperature control meter 9 gradually reduces the opening of the heat-conducting medium inlet control valve 7 through the control line 10, reduces the heat exchange amount of the heat-conducting oil to the inner air pipe 3, and gradually reduces the actually measured temperature of the temperature sensor 8 to the process set value on the temperature control meter 9. When the actually measured temperature of the temperature sensor 8 is lower than the process set temperature on the temperature control meter 9, the temperature control meter 9 gradually increases the opening of the heat-conducting medium inlet control valve 7 through the control line 10, increases the heat exchange amount of the heat-conducting oil to the inner gas pipe 3, and gradually increases the actually measured temperature of the temperature sensor 8 to the process set value of the temperature control meter 9.
The second electric heating mode 2 is as follows: when the inner air pipe 3 is heated without heat transfer oil, the cold air enters the electric heating mechanism 2 through the inner air pipe 3, and the electric heating mechanism 2 heats the cold air. Because the cold air needs to be heated to the process set temperature after passing through the electric heating mechanism 2, the temperature sensor 8 is added at the outlet of the electric heating mechanism 2 to measure the temperature actually. The process temperature is set on the temperature control meter 9, when the temperature actually measured by the temperature sensor 8 is higher than the process set temperature on the temperature control meter 9, the heating output current of the electric heating mechanism 2 is gradually reduced after the temperature control meter 9 passes through the control line 10 below, the heating power of the electric heating mechanism 2 is reduced, and the actually measured temperature of the temperature sensor 8 is gradually reduced to the process set value on the temperature control meter 9. When the actually measured temperature of the temperature sensor 8 is lower than the process set temperature of the temperature control meter 9, the temperature control meter 9 passes through the control line 10, the heating output current of the electric heating mechanism 2 is gradually increased, the heating power of the electric heating mechanism 2 is increased, and the actually measured temperature of the temperature sensor 8 is gradually increased to the process set value of the temperature control meter 9.
During normal production, the drying energy-saving heater adopts the heating principle of the first inner air pipe 3, the heating does not need power-consuming heating, and heat conduction oil produced by a boiler is adopted for heat exchange, so that the aims of greatly saving energy and reducing consumption are fulfilled. When the boiler breaks down, no heat conducting oil enters the inner air pipe 3 for heat exchange, the actually measured temperature of the temperature sensor 8 below the boiler is gradually reduced to the process set temperature on the temperature control meter 9, the electric heating mechanism 2 gradually increases the heating power, and the electric heating mechanism 2 is adopted for heating. After the boiler is repaired and heat conducting oil is introduced, two kinds of heating of the first inner gas pipe 3 and the second electric heating mechanism 2 are carried out synchronously, the temperature is increased, the actually measured temperature of the temperature sensor 8 is gradually higher than the process set temperature on the temperature control meter 9, the heating output current of the electric heating mechanism 2 is gradually reduced, the heating power of the electric heating mechanism 2 is reduced and gradually reduced to 0, and the purpose of automatic switching is achieved. The two types of heating can be automatically switched, so that the drying energy-saving heater can run in an energy-saving mode for a long time, and when the boiler is in fault shutdown, the heating of the drying energy-saving heater is switched to the electric heating mechanism 2 through the inner air pipe 3, the long-term running is kept, the shutdown is avoided, and the integral energy-saving effect of stable running is guaranteed.
