Description

Technical Field

[0001] This invention relates to the field of resource utilization technology for overhaul slag, and more particularly to a resource utilization device suitable for overhaul slag. Background Technology

[0002] Overhaul slag, a representative hazardous waste from industries such as electrolytic aluminum and storage batteries, mainly originates from the waste linings replaced during electrolytic cell overhauls and the battery dismantling process. Its hazardous waste codes cover multiple categories, including HW321-023-48 and HW31, and its composition is complex and significantly toxic, containing high concentrations of soluble fluorides, cyanides, and various heavy metal compounds. Industry data shows that a single electrolytic cell overhaul can generate approximately 100 tons of overhaul slag, with the fluoride leaching concentration in the slag component reaching as high as 13,000 mg / L, and the cyanide content in the carbon blocks reaching 6.8 mg / L.

[0003] Currently, existing technologies for treating overhaul slag in the industry are mainly divided into two categories: pyrometallurgical and hydrometallurgical methods. However, both have significant limitations: pyrometallurgical treatment removes harmful components through high-temperature combustion, but suffers from high energy consumption, large carbon dioxide emissions, and severe equipment corrosion; hydrometallurgical treatment, while capable of converting toxic substances through chemical reactions, requires expensive reagents and suffers from incomplete sodium removal and fluorine extraction, as well as low aluminosilicate utilization. In the pretreatment stage, traditional crushing and grinding systems often use single crushing equipment, which is prone to material jamming when dealing with overhaul slag of varying shapes. The mixing of large and small particles leads to low crushing efficiency. In the subsequent separation process, problems such as incomplete solid-liquid separation and a fluorine resource recovery rate of less than 55% further restrict the resource utilization benefits.

[0004] Therefore, it is necessary to develop a resource-based treatment device for overhaul slag that is highly integrated, efficient in crushing and grinding, and fully recovers resources. Summary of the Invention

[0028] like Figure 1 and Figure 6 As shown, the buffer assembly 11 includes a fixed block 111, a sliding rod 112, a fixed rod 113, and an elastic element 115. The fixed block 111 is rotatably arranged on the right side of the crushing box 51, and the sliding rod 112 is inclinedly slidably arranged on the fixed block 111. The fixed rod 113 is rotatably arranged on the lower part of the right side wall of the extrusion plate 54. A ring 114 is provided on the left end of each sliding rod 112. The ring 114 is sleeved with the fixed rod 113. An elastic element 115 is sleeved on the sliding rod 112. One end of the elastic element 115 is connected to the fixed block 111, and the other end of the elastic element 115 is connected to the end of the fixed rod 113.

[0029] like Figure 1 and Figure 7 As shown, the feeding assembly 14 includes a first rotating shaft 141, a feeding plate 142, and a drive motor 143. The first rotating shaft 141 is rotatably mounted on the upper part of the discharge end of the screen slide 8. The feeding plate 142 is mounted on the first rotating shaft 141 and contacts and cooperates with the arc-shaped piece 81. The drive motor 143 is mounted on the screen slide 8, and the output shaft of the drive motor 143 is connected to the first rotating shaft 141.

[0030] like Figure 1 and Figure 8 As shown, it also includes a mixing component 16, which includes a mounting plate 161, a second rotating shaft 162, stirring blades 163, and a rotary motor 164. The first processing box 12 and the second processing box 13 are both equipped with mounting plates 161. The second rotating shaft 162 is rotatably mounted on the mounting plate 161. The stirring blades 163 are arranged at the lower part of the second rotating shaft 162. The rotary motor 164 is mounted on the mounting plate 161, and the output shaft of the rotary motor 164 is connected to the second rotating shaft 162.

[0031] When overhaul slag needs to be processed, the staff starts the conveyor belt 3, which transports the overhaul slag that needs to be processed for resource utilization to the right into the feed hopper 4. The first servo motor 56 is started. The first servo motor 56, through continuous forward and reverse rotation, can drive the extrusion plate 54 to swing through the transmission component 57. When the extrusion plate 54 swings to the left, it cooperates with the fixed pressure plate 52 to crush the overhaul slag. Since the ring 114 is sleeved with the fixed rod 113, the swing of the extrusion plate 54 drives the sliding rod 112 to slide accordingly through the ring 114, and the elastic element 115 is stretched. When the extrusion plate 54 swings to the right to reset, the ring 114 and the fixed rod 113 slide upward, and the elastic element 115 resets. The primary crushing component 5 can transport overhaul slag for preliminary crushing. After crushing, the slag falls into the feed channel 77. The motor of the electric conveyor component 78 is started, and the motor drives the auger to rotate, thus conveying the pre-crushed slag into the rotating drum 71. Since the rotating drum 71 contains a large number of high-chromium alloy balls, when the second servo motor 73 is started, it drives the large pulley 72 to rotate through the small pulley 74 and the flat belt 75, thereby rotating the rotating drum 71. The high-chromium alloy balls rotate along the spiral blades on the inner wall and then fall to impact and crush the overhaul slag. During the rolling, the overhaul slag is squeezed, sheared and ground. The ground powder will fall into the screen slide 8 through the circular screen 76. The water pump 104 is started, and the water pump 104 feeds the slag through the inlet pipe 105. Water is drawn from tank 107 and sprayed through inlet branch pipe 106 and nozzle 103 to wash the ground overhaul residue powder. This process dissolves soluble fluorides and cyanides in the water, which then flows into the first treatment tank 12. The waste residue slides downwards to the lower part of the screen slide 8. Driven by motor 143, the material-pushing plate 142 moves the waste residue through the arc-shaped plate 81 into the second treatment tank 13. Vibrator 9 facilitates the downward sliding of the waste residue. Aluminum salt is added to the first treatment tank 12, and the rotary motor 164 drives the second rotating shaft 162 and stirring blades 163 to stir and mix the residue, promoting the formation of insoluble aluminum fluoride precipitate. Subsequent solid-liquid separation, filtration, and impurity removal are performed. The treated liquid is then evaporated and crystallized to form useful sodium fluoride. In the second treatment tank 13, the solid is treated by opening the valve of liquid cylinder 15 and adding sulfuric acid. The sulfuric acid reacts with the waste residue through acid leaching. The rotary motor 164 drives the second rotating shaft 162 and stirring blades 163 to align and mix the residue. Then, through solid-liquid separation, useful cement kiln auxiliary materials are formed, and the liquid undergoes further processing to form useful products. This device has a simple structure and can quickly complete the resource recycling and treatment of overhaul slag.
