Technical Field

The aging furnace proposed by the utility model can be used for aging treatment of long and medium-sized materials in rail passenger car manufacturing. The aging furnace uses a furnace body heating rod and a fan to realize hot air circulation in the furnace, and by setting a hot air compensation system on the furnace body near one end of the furnace door, the hot air compensation system further improves the uniformity of air supply in the aging furnace, thereby improving the heating uniformity of the materials to be aged and improving the qualified rate of the products.

This is inefficient. In view of this, we propose an energy-saving temperature regulation structure for the aging furnace. Utility Model Content

[0034] Specifically, one end of the water outlet pipe 22 is connected to a heat exchanger 23 for heat exchange, and the water outlet end of the heat exchanger 23 is connected to a refrigerator 24 for cooling.

[0035] It should be added that the water outlet of the refrigerator 24 is connected to a water return pipe 25 , one end of which is connected to the water inlet of the water pump 21 for guiding water from the refrigerator 24 back to the water pump 21 .

[0036] As a preferred embodiment of the present invention, an air intake regulating mechanism 3 is provided on the top of the furnace body 1, and the air intake regulating mechanism 3 includes an air pump 31. The air pump 31 is fixedly connected to the left side surface of the outer shell 16 by bolts. The air pump 31 sucks the air in the furnace body 1 through the air intake pipe 33 and introduces the air into the outer shell 16 through the air outlet pipe 32.

[0037] Specifically, the air outlet of the air pump 31 is connected to an air outlet pipe 32 , and the right end of the air outlet pipe 32 passes through the left end of the housing 16 for introducing air into the housing 16 .

[0038] Specifically, the air inlet of the air pump 31 is connected to an air inlet pipe 33 , and the bottom end of the air inlet pipe 33 passes through the top of the furnace body 1 for sucking the air in the furnace body 1 .

The refrigerated water is guided back to the water pump 21 through the return pipe 25 to form a cold water cycle, so that the temperature of the air in the housing 16 that contacts the surface of the return pipe 25 is reduced.

[0045] Open the valve 18 and the air pump 31. The air pump 31 sucks the air in the furnace body 1 through the air inlet pipe 33 and introduces the air into the outer shell 16 through the air outlet pipe 32, driving the air in the outer shell 16 with the temperature reduced to pass into the furnace body 1 through the air guide pipe 17, so that the temperature inside the furnace body 1 is reduced;

[0046] When it is necessary to adjust the speed at which the temperature inside the furnace body 1 is lowered, turn on the rotating motor 34, which drives the threaded rod 35 to rotate, thereby driving the movable plate 36 to move to the left, thereby driving the baffle 37 to move to the left, so that the amount of air intake into the air intake pipe 33 increases within the same period of time, thereby increasing the speed at which the temperature inside the furnace body 1 is lowered, until the speed at which the temperature inside the furnace body 1 is lowered reaches the specified speed, and then turn off the rotating motor 34.

[0047] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
