DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-5The utility model provides a technical solution: a graphitization furnace for negative electrode materials with an ultra-low flue gas emission treatment mechanism, comprising a graphitization furnace body 1, a flue gas duct 2, a flue gas treatment box 3, an activated carbon filter 4, a cleaning brush 5, a movable column 6, an electric telescopic rod 7, a connecting block 8, a movable sleeve 9, a fixing rod 10, a fixing plate 11, a connecting mechanism 12, an auxiliary plate 13, a spring 14, a mounting plate 15, a limit block 16, a fixing pin 17 and a limit plate 18.

[0030] When using the negative electrode material graphitization furnace with ultra-low flue gas emission treatment mechanism, if Figure 1 , Figure 2 and Figure 3 As shown, when the flue gas generated in the graphitization furnace body 1 enters the flue gas treatment box 3 through the flue gas pipe 2, the activated carbon filter 4 is installed in the flue gas treatment box 3. Through the setting of the activated carbon filter 4, the flue gas can be filtered and purified to prevent the flue gas from being directly discharged to the outside and causing serious pollution to the atmospheric environment. The filtered and purified flue gas is discharged to the outside through the connection port at the left end of the graphitization furnace body 1. In addition, in the actual filtering process, the electric telescopic rod 7 installed at the rear end of the flue gas treatment box 3 is started, and the output end of the electric telescopic rod 7 is fixedly connected with a connecting block 8. The electric telescopic rod 7 drives the connecting block 8 to move forward and backward inside the flue gas treatment box 3. At this time, the connecting block 8 rotates with the movable sleeve 9, driving the movable sleeve 9 to slide up and down on the outer surface of the fixed rod 10, and the upper end of the fixed rod 10 slides between the fixed plate 11, thereby improving the stability of the fixed rod 10 during movement.

[0031] At this time, the fixed rod 10 drives the movable column 6 to rotate in the middle of the flue gas treatment box 3, and the left end of the movable column 6 is fixedly connected with a cleaning brush 5, which is fitted on the side of the activated carbon filter 4, thereby driving the cleaning brush 5 to swing back and forth in the temporal part of the flue gas treatment box 3, so that the cleaning brush 5 continuously cleans the outer surface of the activated carbon filter 4, prevents dust particles in the flue gas from clogging the activated carbon filter 4, keeps the activated carbon filter 4 unobstructed, and thus achieves a better filtering effect;

[0032] In addition, after use, combine Figure 4 and Figure 5As shown, the activated carbon filter 4 and the flue gas treatment box 3 are limited by a connecting mechanism 12, and the connecting mechanism 12 includes an auxiliary plate 13 fixedly connected to the upper right end of the activated carbon filter 4, a spring 14 arranged inside the auxiliary plate 13, a mounting plate 15 fixedly connected to the movable end of the spring 14, a limiting block 16 for connection and a fixing pin 17 for positioning. The mounting plate 15 can slide with the auxiliary plate 13 by pulling the pull ring at the right end of the mounting plate 15, and at the same time, the mounting plate 15 slides with the limiting block 16. At this time, the mounting plate 15 squeezes the spring 14, causing the spring 14 to undergo elastic deformation, and the mounting plate 15 drives the fixing pin 17 to expand and contract, causing the fixing pin 17 to be pulled out from the limiting plate 18, thereby loosening the limit between the flue gas treatment box 3 and the activated carbon filter 4, and then pulling the activated carbon filter 4 upward. At this time, the activated carbon filter 4 is pulled out of the flue gas treatment box 3, making it convenient to fully clean or replace the activated carbon filter 4, and convenient to disassemble and assemble the activated carbon filter 4 and the flue gas treatment box 3, which is very convenient to use.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
