Description

Technical Field

[0001] This utility model relates to the field of electrolytic aluminum technology, and more specifically to a dust collection and treatment device for electrolytic aluminum production. Background Technology

[0002] Electrolytic aluminum is aluminum obtained through electrolysis. Modern industrial electrolytic aluminum production uses the cryolite-alumina molten salt electrolysis method. Molten cryolite is the solvent, alumina is the solute, carbonaceous material is used as the anode, and molten aluminum is used as the cathode. After a strong direct current is applied, an electrochemical reaction occurs at the two electrodes in the electrolytic cell at 950°C-970°C, which is called electrolysis. In traditional electrolytic aluminum production, to ensure production efficiency and safety, the anode rods usually need to be replaced periodically. During the replacement process, a large amount of dust and fugitive fumes are generated. To avoid pollution to the production environment, a dust collection and treatment device is used to collect and treat the dust generated during anode rod replacement.

[0003] A search revealed an existing patent (publication number: CN217570108U) that discloses a fugitive gas collection device for electrolytic aluminum production. When used for anode rod replacement, this device uses a collection hood, a gas collecting pipe, and a fan to guide the dust and fugitive gas generated during anode rod replacement into a filter box. The filter plate then intercepts the dust carried in the gas, and the treated gas is then guided through a gas pipe into a purification tank for further purification. This process effectively collects and purifies the dust and fugitive gas generated during anode rod replacement, preventing pollution of the working environment and surrounding ecosystem, thus improving the efficiency of electrolytic aluminum production. However, the inventors discovered the following problems with the existing technology during the development of this invention: While the aforementioned gas collection device uses a collection hood to collect dust during anode rod replacement, the hood's fixed position makes it difficult to adjust according to the replacement position of the external anode rod. This results in poor adjustability of the collection hood for dust collection, failing to meet the need for flexible use.

[0004] In view of this, the present invention proposes a dust collection and treatment device for electrolytic aluminum production, which aims to solve the problems of fixed position and poor adjustability of the collection hood in the prior art, so as to meet the flexible use requirements of dust collection when the anode guide rod is replaced in the electrolytic aluminum production process.

[0025] A filter box 5 is fixedly connected to the top of the dust collection box 3. The bottom of the filter box 5 is connected to the top of the dust collection box 3. An air inlet telescopic hose 6 is embedded in the left end of the filter box 5. An air inlet hood 7 is fixedly connected to the air inlet end of the air inlet telescopic hose 6. An exhaust fan 8 is installed on the inner wall of the air inlet hood 7, and the air outlet end of the exhaust fan 8 corresponds to the air inlet end of the air inlet telescopic hose 6. A filter screen plate 27 is installed on the inner wall of the filter box 5. An activated carbon adsorption plate 9 is installed on the inner wall of the clean air box 4.

[0026] This dust collection and treatment device for electrolytic aluminum production directs the air intake hood 7 towards the external area. Utilizing the airflow driven by the exhaust fan 8, the external airflow is sequentially transported through the air intake hood 7 into the filter box 5 and the clean air box 4. Employing a dual filtration and purification structure of filter screen 27 and activated carbon adsorption plate 9, it effectively intercepts large particulate impurities in the dust and further adsorbs and purifies harmful substances in the flue gas, effectively protecting the working environment and the surrounding ecological environment.

[0035] It is worth noting that the filter screen 27 adopts a double-layer design, and together with the automatic cleaning mechanism consisting of the drive motor 21, crankshaft 22, transmission rod 23 and cleaning slide 24, it can regularly clean the filter screen 27 to prevent dust accumulation from affecting the filtration effect and maintain the continuous and efficient operation of the device.

[0036] A cleaning port is provided on the front of the dust collection box 3, and a cleaning door 26 is detachably installed on the front of the dust collection box 3 corresponding to the cleaning port by bolts.
