[0011] The transmission system chain (10) is entirely arranged in the furnace body wrapped by the furnace shell (1) and the furnace lining (2);

[0012] The feeding port and the discharging port are arranged at the same position of the furnace body.

[0013] Preferably, the feeding port and the discharging port are provided with furnace doors.

[0014] Preferably, the feeding port and the discharging port are arranged at the same position of the middle of the furnace body, one end of the furnace body or the other end of the furnace body.

[0015] Preferably, the new type of drag chain type suspension tempering furnace further comprises a circulating fan (6) and an electric heating pipe (7).

[0016] Preferably, the circulating fan (6) and the electric heating pipe (7) are more than two.

[0017] Preferably, the new type of drag chain type suspension tempering furnace further comprises a wind guide system (4).

[0018] The utility model has the following beneficial effects:

[0019] The utility model uses the hanging basket support bracket assembly, and the workpiece can cover all the bracket assemblies, and the drag chain (transmission system chain) returns full load, so that the length of the tempering furnace equipment is shortened, the land occupation area is small, the number of circulating fans and electric heating pipes can be reduced, and the cost can be reduced.

[0020] The utility model sets the feeding port and the discharging port as one port for feeding and discharging the workpiece, and the transmission system chain is arranged in the interior of the tempering furnace body, so that heat dissipation is small, heat loss is small, and energy is saved efficiently.

[0021] The utility model has the advantages of simple and compact structure, reliable performance and convenient maintenance. DRAWINGS
