Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, an auxiliary device for a rapid temperature raising and lowering furnace comprises a shell 1, an inner furnace 8 and a heating resistor 5 embedded on the wall of the inner furnace 8, wherein the inner furnace 8 and the shell 1 are distributed in a shape of a Chinese character 'hui', a cooling water pipe 9 is arranged between the inner furnace 8 and the shell 1, radiators 2 are arranged on two sides of the shell 1, a fan 3 is arranged on one side of each radiator 2, the cooling water pipe 9 is in an S shape and penetrates into the radiators 2, the cooling water pipe 9 is connected with an expansion water tank 10, the expansion water tank 10 comprises a tank body 101, a water pressure gauge 102 and a pressure limiting valve 103, the tank body 101 is fixed on the upper side of the shell 1, the cooling water pipe 9 penetrates into the tank body 101, the water pressure gauge 102 and the pressure limiting valve 103 are embedded on the upper wall of.

In this embodiment, heating resistor 5 is the silicon molybdenum rod, and is equipped with the multiunit, and evenly distributed is in 8 furnace both sides of interior stove and upper wall, when guaranteeing even heating, raises the thermal efficiency as far as possible, heats through multiunit heating resistor 5, raises the power, simultaneously because adopt the silicon molybdenum rod, bears the load big, and long service life, simultaneously for old-fashioned stove, more energy-conserving.
