Abstract

The invention discloses a split type thermal treatment furnace draught fan. The draught fan comprises a draught fan motor, a motor support, a detachable coupling, fan blades, a fan blade fixing nut, a furnace body, a motor rotating shaft and a draught fan rotating shaft, the draught fan motor is fixed to the upper portion of the motor support, the motor rotating shaft and the draught fan rotating shaft are connected in the motor support through the detachable coupling, the fan blades are fixed to the outer end of a draught fan shaft through a key and the fan blade fixing nut, a water-cooling oil-lubricating bay transmission device is arranged between the motor support and the furnace body, the upper portion and the lower portion of the water-cooling oil-lubricating bay transmission device are fixed to the bottom of the motor support and the upper portion of the furnace body through nuts respectively, and the draught fan rotating shaft passes through a water-cooling oil-lubricating bay. According to split type thermal treatment furnace draught fan, the water-cooling oil-lubricating bay is additionally arranged to improve sealing performance of the furnace draught fan, therefore, the furnace draught fan can meet the requirement, for sealing performance, of a carburizing furnace or a vacuum furnace, and meanwhile the modularization maintenance function of the furnace draught fan can be achieved.

Description

technical field [0001] The invention relates to a heat treatment furnace fan, in particular to a split heat treatment furnace fan. Background technique [0002] The heat treatment furnace fan is an important part of the uniformity of the furnace temperature and atmosphere of the heat treatment equipment, and the coupling end shaft of the heat treatment furnace fan and the fan blade is very easy to be damaged by high temperature oxidation and corrosion, and the fan motor rotor shaft of the integral heat treatment furnace is integrated with the fan blade shaft, so due to The damage of the end shaft of the fan blade causes the entire fan to be scrapped. [0003] At present, there is a Chinese invention patent with the application number 201210100002.9 disclosing a heat treatment furnace fan that separates the rotating shaft and connects it through a detachable coupling, but it can only meet the needs of easy replacement of parts, and cannot meet the needs of carburizing furnace...
