[0014] A furnace upper cover 1 is installed on the furnace shell main body 2 .

[0015] The inlet 3 and the outlet 12 are symmetrically arranged.

[0016] When the present invention is working, the carbon felt 10 enters one side of the interior of the furnace shell body 2 from the inlet 3, passes through the first layer of rollers, bends upward, passes through the second layer of rollers, passes through the first tightening roller 9, and then goes to the rollers of the second layer of the furnace cavity, and repeats this process until it reaches the rollers of the uppermost layer of the furnace cavity; then it passes through the first tightening roller 14 on the middle layer of the thermal insulation material 6 and enters the other side of the interior of the furnace shell body 2. At this time, the carbon felt is transported downward layer by layer by the rollers and the first tightening roller until it reaches the outlet 12 of the lowermost layer.

[0017] Each layer of the furnace shell body 2 is provided with two layers of rollers, and a number of quartz heating tubes are provided between the two layers of rollers. Two rows of quartz heating tubes are provided between each layer to ensure that both sides of the carbon felt are heated evenly.

[0018] The utility model includes a furnace cover 1, which is installed on the furnace shell main body 2, and rollers 7 are inserted through the holes in the transmission control bin 4 installed on each layer. An external drive guide device is used to ensure that the carbon felt 10 passes slowly from the surface of the roller 7 in sequence, and the quartz heating tube 8 is inserted into the cranial cavity through the hole on the electrode protection bin 11 to increase the temperature and heat; a layer of thermal insulation material 6 is laid on the inner wall of the furnace shell main body 2 and another layer is built in the middle to divide the furnace cavity into two parts to prevent the felt from entering and exiting, and the carbon felt and the heating tube from interfering with each other; at the same time, a first tightening roller 9 is provided on a layer built between both sides of the furnace cavity and the thermal insulation material 6 to ensure that the carbon felt passes continuously and smoothly through the rollers 7 at various locations in the cranial cavity.

[0019] A passage is opened in the bottom layer of the furnace shell body 2 to install the components of the inlet and outlet 3 and the outlet 12. At the same time, a hole is opened above the transmission control compartment 4 and the electrode protection compartment 11 outside the bottom layer of the shell body 2 to install the coke discharge pipe 5.
