[0015] A roasting method for a roasting device for pre-baking anode carbon blocks, comprising the following steps:

[0016] S1: First, after the prebaked anode carbon blocks are mixed and formed, the prebaked anode carbon blocks are transported to one side of the extended access slot through the conveying device for automatic material retrieval, and the other side of the extended access slot is used for automatic material storage;

[0017] S2: When the material is ready, the electric slide rail is started to drive the electric slide seat to move the column, and the transfer assembly is moved to the top of the extended access slot for taking the material, and then the drive motor is started to adjust the position of the slide frame so that the clamping plate is located above the prebaked anode carbon block;

[0018] S3: Then the hydraulic rod is started to adjust the height of the placement frame. When the placement frame moves downward, the clamping plate approaches the prebaked anode carbon block, and the hollow shaft motor is started to make the clamping plate clamp the prebaked anode carbon block. After clamping, the prebaked anode carbon block is stored in the corresponding baking chamber using the electric slide rail and the slide frame;

[0019] S4: After storage, the clamping plate moves up and approaches the prebaked anode carbon block, and the feed pump is started to pump the filling material inside the storage box into the feeding pipe, and then it is discharged from the control pipe. After discharge, the sliding frame reciprocates to realize the leveling brush plate to level the filling material;

[0020] S5: After the leveling is completed, the next prebaked anode carbon block can be stored. After the prebaked anode carbon block is stored, the tubular burner is started to heat the heat storage tank to realize the baking of the prebaked anode carbon block in the baking chamber, wherein the baking time is - hours;

[0021] S6: After the roasting is completed, the three-way switching valve is switched, and then the extraction pump is started so that the material control pipe cooperates with the reflux pipe to extract the filling material, and then the anode carbon blocks after roasting are stored in the extended access slot on the other side using the clamping plate, and finally the above steps are repeated in sequence until all the anode carbon blocks are taken out, and the roasting of the anode carbon blocks is completed.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. By setting up two extended access slots, the pre-baked anode carbon blocks after forming can be pre-transported to one of the extended access slots according to processing needs, so as to facilitate the transfer of the transfer assembly, and the other extended access slot can be used to uniformly receive and store the anode carbon blocks after baking. The extended access slot can facilitate the management of the anode carbon blocks and improve the efficiency under automatic baking.

[0024] 2. The electric slide can be driven to move by the electric slide rail, and the driving motor can be used to drive the driving screw to rotate and drive the sliding frame to move, so that the clamping plate can be moved to any position, and the height of the placement frame can be adjusted in conjunction with the hydraulic rod to realize automatic storage and retrieval of the anode carbon blocks. Compared with the existing manual storage, the present application is better in the arrangement speed of the anode carbon blocks, and also improves the overall roasting efficiency.

[0025] 3. By starting the hollow shaft motor to drive the forward and reverse screws to rotate, and by using the limit seat and the limit groove to cooperate, the second screw sleeve and the forward and reverse screws can drive the limit seats on both sides to move relative to each other when the threads cooperate, so as to realize the clamping control of the clamping plate to meet the subsequent automatic clamping transfer operation;

[0026] A leveling brush plate is installed at the bottom of the clamping plate to level the upper material when the filling material is discharged, so as to improve the subsequent roasting quality. In order to avoid damaging the anode carbon block, a support spring is arranged between the clamping plate and the movable groove, so that the clamping plate will not collide when it is close to the anode carbon block, thereby avoiding the breakage of the pre-baked anode carbon block, improving the stability of the roasting process and reducing the defective rate.

[0027] 4. In order to improve the roasting effect before roasting, it is necessary to add filler after the pre-baked anode carbon blocks are placed in the roasting chamber. The connection between the material control pipe and the feed pipe and the reflux pipe can be switched through the three-way switching valve. The filler can be discharged into the roasting chamber through the feed pump, and the extraction pump extracts the filler to avoid affecting the subsequent roasting. The above structure allows the present application to automatically transfer the anode carbon blocks while automatically filling and discharging the filler, further improving the efficiency during roasting.

After clamping, the electric slide rail (2) and the slide frame (3034) are used to store the prebaked anode carbon block into the corresponding baking chamber (6); S4: After the storage, the clamping plate (3072) moves upward and approaches the prebaked anode carbon block, and the feed pump (504) is started to pump the filling material in the storage box (501) into the feeding pipe (503), and then discharges it from the control pipe (506). After discharge, the sliding frame (3034) reciprocates to realize the leveling brush plate (3073) to level the filling material; S5: After the leveling is completed, the next prebaked anode carbon block can be stored. After the prebaked anode carbon block is stored, the tubular burner (7) is started to heat the heat storage tank (10) to achieve the roasting of the prebaked anode carbon block inside the roasting chamber (6), wherein the roasting time is 24-48 hours; S6: After the roasting is completed, the three-way switching valve (507) is switched, and then the extraction pump (505) is started, so that the material control pipe (506) cooperates with the reflux pipe (502) to extract the filling material, and then the anode carbon blocks after roasting are stored in the extended storage slot (8) on the other side using the clamping plate (3072). Finally, the above steps are repeated in sequence until all the anode carbon blocks are taken out, and the roasting of the anode carbon blocks is completed.
