An inlet driving roller 11 is arranged on the outer side of an inlet of the low carbon furnace, an outlet driving roller 12 is arranged on the outer side of an outlet of the low carbon furnace, carbon fibers 10 are wound on the inlet driving roller 11 and penetrate into the low carbon furnace 1 from an inlet 13 of the low carbon furnace, then pass through an outlet 14 of the low carbon furnace and are wound on the outlet driving roller 12, and the carbon fibers can smoothly pass through the low carbon furnace 1 for treatment through the traction and tensioning of the inlet driving roller 11 and the outlet driving roller 12.
As shown in figure 1, the device for online cleaning the high-performance carbon fiber low-carbon furnace comprises a material pushing device 9, a winding device, a chain and a settling chamber.
The two settling chambers are disposed below the first temperature zone near the inlet 13 of the low carbon furnace and below the last temperature zone near the outlet 14 of the low carbon furnace, respectively. A settling chamber, namely a head settling chamber 2a of the low-carbon furnace, is arranged below the first temperature zone of the low-carbon furnace, and a settling chamber, namely a tail settling chamber 2b of the low-carbon furnace, is arranged below the last temperature zone of the low-carbon furnace.
The pushing device 9 is arranged in the low carbon furnace 1, the winding device is arranged outside the low carbon furnace 1, and the winding device is connected with the pushing device 9 through a chain 8 to drive the pushing device 9 to move back and forth between an inlet and an outlet of the low carbon furnace 1, so that the bottom sediment of the furnace and the residual broken filaments and tar block substances are pushed into the two settling chambers.
In order to enable the pushing device to more effectively achieve the purpose of pushing the bottom sediment of the furnace and residual broken filaments and tar cake substances, the pushing device 9 is made of a steel grid plate made of 602CA materials.
The winding device is an electric winding device and comprises winding drums and a motor, wherein the two winding drums are respectively arranged at the inlet end and the outlet end of the low-carbon furnace 1.
Four angles of the steel grid plate are respectively connected with the two winding drums through 602CA steel chains.

Therefore, the carbon fibers 10 are not hindered from moving in the low carbon furnace 1 when the chain 8 pulls the steel grid plate of the material pushing device 9 to move, and the bottom sediment of the low carbon furnace 1 and residual broken filaments and tar cake substances can be pushed to the settling chamber.

The gate valve comprises an upper gate valve 3 and a lower gate valve 4 which are arranged up and down. The two valves can not be opened simultaneously, the upper-layer gate valve 3 is opened firstly, after the broken filaments and tar block substances fall to the lower-layer gate valve 4, the upper-layer gate valve 3 is closed, and then the lower-layer gate valve 4 is opened to discharge the broken filaments, tar block substances and other deposits from the slag discharge port.
