The utility model relates to a thermal cycle device of a Roots pump, and belongs to Roots pump equipment. According to the main technical scheme, the heat circulation device comprises a lobe pump, a heating cavity is formed in the lobe pump, the heat circulation device further comprises a heat supply mechanism, the heat supply mechanism comprises a water inlet pipe and a water outlet pipe, one endof the water inlet pipe is connected with a hot water source, the other end of the water inlet pipe is communicated with the heating cavity, and one end of the water outlet pipe is connected with theheating cavity. The other end is communicated with the outside. When the lobe pump is used, on one hand, gas in the sintering furnace is pumped into the pump through the vent pipe, on the other hand,the hot water is pumped into the pump through the water inlet pipe, the hot water enters the lobe pump and then heats the lobe pump, the overall temperature of the lobe pump is increased, the gas entering the lobe pump cannot
