Description
Technical Field
[0001] The utility model belongs to the technical field of aluminum electrolytic cells, and in particular relates to a configuration structure of a material discharge point of a prebaked aluminum electrolytic cell. Background Art
[0002] The prebaked aluminum electrolytic cell is a modern large-scale aluminum electrolytic cell. The unloading point of the prebaked aluminum electrolytic cell usually refers to the position where alumina enters the electrolytic cell. Alumina is the main raw material in the aluminum electrolysis production process. It enters the electrolytic cell evenly through the unloading point and reacts with the electrolyte to produce aluminum and oxygen. In actual production, the unloading point of the prebaked aluminum electrolytic cell allows alumina to enter the electrolytic cell through the unloading channel for reaction;
[0003] When the aluminum electrolytic cell is undergoing production reaction, since the aluminum electrolytic cell will produce flue gas, the discharge point is installed in the upper position where it is directly in contact with the flue gas, causing the flue gas to adhere to the discharge pipe. At the same time, the flue gas will reduce the current efficiency, affect the electrolyte composition, damage the inner lining of the electrolytic cell, and be harmful to the health of the workers. It is necessary to install a flue to extract the flue gas to prevent the flue gas from being in the aluminum electrolytic cell. The flue is located in the upper position of the discharge point. When the flue is used for a long time, while continuously absorbing the flue gas, a large amount of flue gas condensate will adhere to the bottom of the tube wall. When the staff cleans the aluminum electrolytic cell, the flue gas condensate on the pipe will fall off, affecting the staff's cleaning work of the aluminum electrolytic cell body and causing pollution to the electrolyte and other hazards.

[0019] In this embodiment: the portal frame 1 is a carrier of the bearing device, and the portal frame 1, the beam 11 and the support plate 12 form a support carrier for the upper structure of the aluminum electrolytic cell, so that the shelling and unloading machine structure can be installed on the support plate 12 and evenly distributed on the portal frame 1, so that it can carry out unloading work. The portal frame 1 is located directly above the aluminum electrolytic cell body, and alumina is put into the device. When the alumina is in the aluminum electrolytic cell for electrolysis reaction, a large amount of smoke is generated above the cell body. In order to prevent the smoke from affecting the normal progress of the electrolysis process, the branch pipe 23 can be installed through a connecting pipe 21 fixedly connected to one of the portal frames 1. The branch pipe 23 is horizontally mounted above the aluminum electrolytic cell body. At this time, the external suction structure can be connected through the branch pipe 23. The docking hole 24 opened at the bottom absorbs the flue gas in the aluminum electrolytic cell. At the same time, the other end of the branch pipe 23 is supported and fixed by the fixing rod 2 fixed on another door frame 1, so that the branch pipe 23 is firmly placed on the cell body to perform flue gas work. At the same time, the position where the docking hole 24 is opened can be connected with the plug block 25. The plug block 25 is inserted into the inner wall of the docking hole 24, and the flue gas in the cell body can enter the branch pipe 23 through the exhaust hole 26 opened on the plug block 25, and be sucked and discharged. After several plug blocks 25 are plugged into several docking holes 24, the connecting rods 27 fixedly connected between the plug blocks 25 can be used to connect and fix the several plug blocks 25 to ensure that the several plug blocks 25 are connected as a whole. At the same time, the two plug blocks at the two ends are connected. The connecting rod 27 fixedly connected to one end of the block 25 is used to install the docking joint 28. At this time, when the plug block 25 is inserted into the docking hole 24, the position of the docking joint 28 can correspond to the screw rod 34 connected to the inner wall of the fixing ring 3. The docking block 35 threadedly connected on the screw rod 34 can correspond to one end of the docking joint 28, so that the docking joint 28 and the docking block 35 are connected and fixed. By rotating the screw rod 34, the docking block 35 can drive the docking joint 28 to move synchronously. Since the docking joint 28 is connected to the plug block 25 through the connecting rod 27, the height of the plug block 25 can be controlled by the docking block 35, so that when it is necessary to absorb the smoke, it is ensured that the plug block 25 is supported by the docking block 35 so that it can be inserted into the docking hole 24. When it is necessary to clean the opening position, the docking joint 28 can be separated from the docking block 35, and several plug blocks 25 can be separated from the device for cleaning. At the same time, when cleaning the branch pipe 23, the semi-annular plate 31 above the branch pipe 23 can be slid, and the semi-annular plate 31 slides on the fixing ring 3 and the fixing rod 2. When smoke is generated, the semi-annular plate 31 is inverted on the top of the branch pipe 23. When the cleaning is finished, it slides down so that the semi-annular plate 31 is under the branch pipe 23, so that the semi-annular plate 31 can receive the smoke residue on it, so as to avoid the smoke residue on the branch pipe 23 from falling into the tank body when cleaning, affecting the staff's cleaning work of the tank body, and at the same time, it can ensure that the smoke residue on the branch pipe 23 can be cleaned in time.Avoid affecting the electrolytic reaction in the electrolytic cell, so that the device can ensure the absorption of flue gas while cleaning the flue gas condensation residue without affecting the electrolyte in the cell.
