[0002] A roasting furnace is a high-temperature processing equipment, also known as a calcining furnace. According to the different energy sources used, it can be divided into four types: coal-fired furnace, gas-fired furnace, oil-fired furnace and electric heating furnace; according to the heating method, it can be divided into two categories: direct heating and indirect heating; according to the operation mode, it can be divided into two types: continuous operation and intermittent operation. It is widely used in the sintering production of graphite products.

[0003] For example, the Chinese patent "CN103954129B A U-shaped multi-stage roasting furnace" with a publication date of October 31, 2017, has a furnace shell that is a hollow arc, and the hollow area of ​​the furnace shell is a furnace chamber. A cover plate is provided on the upper surface of the top of the furnace shell, and the furnace chamber is divided into multiple sections by a baffle. A heating device is provided at one end of the arc furnace shell, and an exhaust fan is provided at the other end of the arc furnace shell. An exhaust pipe is provided on the exhaust fan, and a support rail is provided at the bottom of the furnace chamber. The previous furnace chamber is connected to the next furnace chamber through an air supply pipe, and each furnace chamber is respectively provided with its corresponding heating device. A cyclone separator is provided at the bottom of the air supply pipe. The roasting furnace is structurally divided into multiple sections. The exhaust gas of the previous section can be used as the waste heat gas of the next section, and the oxygen supply gas of the next section can be used as the cooling gas of the previous section, thereby realizing multi-stage utilization of energy, high energy utilization rate, low energy consumption, and small footprint.

[0004] Existing graphite product baking furnaces mostly adopt a single-layer design. Graphite products are usually placed in a single layer or stacked in layers with the help of a support table. In actual application, the internal space utilization rate is low, which easily causes space waste, resulting in high costs for a single sintering. After a single batch of graphite products is sintered and formed, it is necessary to remove the graphite products from the platform one by one, and then place the next batch of graphite products on the idle platform. The loading and unloading process takes a long time, which affects the production efficiency of graphite product sintering. Summary of the invention
