What is claimed is: 1 . A heat treatment device which performs vacuum carburizing treatment by heating a workpiece, the heat treatment device comprising: a heater chamber in which a heater is provided; a heat treatment chamber which is disposed adjacent to the heater chamber and in which the workpiece is heated and vacuum carburizing treatment is performed on the workpiece; a muffle plate which partitions a portion between the heater chamber and the heat treatment chamber; and a gas introduction portion through which burnout gas is introduced and which is independently provided in each of the heater chamber and the heat treatment chamber. 2 . The heat treatment device according to claim 1 , wherein a double exhaust pipe is provided in the heat treatment device, and the double exhaust pipe includes a first exhaust pipe which communicates with the heater chamber, and a second exhaust pipe which communicates with the heat treatment chamber and is inserted into the first exhaust pipe. 3 . The heat treatment device according to claim 1 , wherein the heater chamber is disposed outside the heat treatment chamber and surrounds the heat treatment chamber. 4 . The heat treatment device according to claim 2 , wherein the heater chamber is disposed outside the heat treatment chamber and surrounds the heat treatment chamber. 5 . The heat treatment device according to claim 3 , wherein the heat treatment chamber is formed in a circular shape in a plan view, and a plurality of the heaters are radially disposed in the heater chamber with respect to the center of the heat treatment chamber. 6 . The heat treatment device according to claim 4 , wherein the heat treatment chamber is formed in a circular shape in a plan view, and a plurality of the heaters are radially disposed in the heater chamber with respect to the center of the heat treatment chamber. 7 . The heat treatment device according to claim 3 , wherein a plurality of heater chamber gas introduction portions, through which the burnout gas is introduced into the heater chamber, are radially provided with respect to the heater chamber. 8 . The heat treatment device according to claim 4 , wherein a plurality of heater chamber gas introduction portions, through which the burnout gas is introduced into the heater chamber, are radially provided with respect to the heater chamber. 9 . The heat treatment device according to claim 5 , wherein a plurality of heater chamber gas introduction portions, through which the burnout gas is introduced into the heater chamber, are radially provided with respect to the heater chamber. 10 . The heat treatment device according to claim 6 , wherein a plurality of heater chamber gas introduction portions, through which the burnout gas is introduced into the heater chamber, are radially provided with respect to the heater chamber.
