Description

Technical Field

[0001] The invention relates to the technical field of metallurgical waste treatment, in particular to an automatic leaching system for metallurgical dust and mud. Background Art

[0002] Metallurgical dust sludge is a kind of solid waste generated in the production process of the metallurgical industry. It mainly comes from the flue gas purification systems and dust removal devices of blast furnaces, converters, electric furnaces and other equipment. Due to the high-temperature smelting, ore sintering and other processes in metallurgical production, the smoke and dust generated are deposited after cooling or filtration to form dust sludge with metal oxides as the main component. These dust sludges usually contain metal elements such as iron, zinc, lead, cadmium, and a certain amount of impurities such as carbon, sulfur, and phosphorus. Since some of the metals have recycling value and the dust sludge itself will cause pollution to the environment, how to efficiently treat and utilize metallurgical dust sludge as a resource has become an important research topic in the fields of industry and environmental protection. Metallurgical dust sludge has the characteristics of fine particle size, complex composition, and high water content. It is difficult to treat, but it also has potential resource value.

[0003] The automatic leaching device for metallurgical dust and sludge is a device for treating dust and sludge waste in the metallurgical industry. It integrates the functions of crushing, screening, stirring, leaching, solid-liquid separation and metal recovery. Through automatic control, the device uses leaching liquid to dissolve the metal in the dust and sludge, extracts metal resources after separation, and reduces the pollution of waste to the environment. The device is efficient and environmentally friendly, and can realize the resource utilization of dust and sludge. It is a key technical equipment for waste treatment in the metallurgical industry.

[0004] In the prior art, most metallurgical dust and mud leaching devices use double crushing rollers to crush the dust and mud. The dust and mud are squeezed and sheared by two rollers to achieve material crushing. However, during the crushing process, high-humidity or high-viscosity dust and mud are easily attached to the roller surface, resulting in a decrease in crushing efficiency and even roller blockage. The attached dust and mud cannot be removed in time, which not only affects the continuous operation of the equipment, but also increases the cost of manual intervention and maintenance, and has a significant adverse impact on production efficiency and stability.

[0048] Working principle: When leaching metallurgical dust and mud, first start the control machine 1, so that multiple electronic devices inside the multiple processing platforms 8 are powered on, first pour the dust and mud into the crusher 901, and then the dust and mud are crushed by the relative rotation of the two crushing rollers 904 inside the crusher 901. When the dust and mud are crushed by the crushing rollers 904, the electric push rod 201 can be started, and the electric push rod 201 controls the movement of the cross plate 202. When the cross plate 202 moves, it will drive the two tooth plates 203 to move downward together. Because the tooth plate 203 is meshed with the cylindrical gear 204, when the tooth plate 203 moves, it will control the rotation of the cylindrical gear 204. When the cylindrical gear 204 rotates, the transmission shaft 205 inside it will The protective shell 206 rotates accordingly, so that the transmission shaft 205 drives the protective shell 206 to rotate together. When the protective shell 206 rotates, the mounting block 207 and the cleaning knife 208 change accordingly, so that the cleaning knife 208 contacts the crushing roller 904. When the cleaning knife 208 contacts the dust and mud on the periphery of the crushing roller 904, a thrust is applied to the connecting rod 1 301, so as to control the movement of the connecting rod 1 301 and the slide plate 302. When the slide plate 302 moves, it moves along the support rod 304 and squeezes the spring 1 303. After the spring 1 303 is squeezed, a corresponding reset thrust is provided, so as to support the connecting rod 1 301, so that the cleaning knife 208 always contacts the crushing roller 904, so as to reduce the mud adhesion on the periphery of the crushing roller 904.

[0049] The crushed dust mud will enter the interior of the screening machine 903, and the crushed dust mud can be screened by starting the screening machine 903, so that the qualified dust mud will enter the mixing tank 1001 through the feeding pipe 1003, and after the dust mud enters the feeding pipe 1003, the leachate can be transported through the saline-alkali solution tank 902 and the liquid delivery pipe 1002, so that the leachate and the dust mud enter the mixing tank 1001, and after the dust mud and the leachate enter the mixing tank 1001, the motor 4 can be started. 01, the dust mud and the leaching liquid are stirred and mixed to dissolve the metal elements in the dust mud into the leaching liquid. After the motor 401 is started, the motor 401 will drive the planetary frame 402 to rotate together, so that the planetary frame 402 drives the connecting ring 403 to rotate, and when the motor 401 rotates, the cylindrical gear 2 405 is also controlled to rotate. When the planetary frame 402 and the connecting ring 403 rotate, the cylindrical gear 3 406 will revolve in the direction of rotation of the planetary frame 402, and because the cylindrical gear 3 406 meshes with cylindrical gear 2 405 and gear ring 404, so that when cylindrical gear 2 405 rotates, the tooth meshing relationship is used to control the corresponding rotation of cylindrical gear 3 406, so that cylindrical gear 3 406 drives stirring rod 407 to rotate, and when stirring rod 407 rotates, stirring blade 408 is driven to rotate together, so that the sludge and leachate are mixed, and when stirring blade 408 contacts leachate and sludge, stirring blade 408 will produce corresponding rotation, and when stirring blade 408 rotates, connecting rod 2 501 is driven to rotate together, and when connecting rod 2 501 rotates, rotating disk 502 is driven to rotate together, and the rotation of rotating disk 502 drives connecting rod 503 and movable block 504 to rotate together, and movable block 504 will stretch spring 2 505 when rotating, and spring 2 505 will provide corresponding force after stretching, so that stirring blade 408 can automatically change angle according to flow change of leachate and sludge, so as to better mix;

[0050] After the mixing is completed, the mixed leachate can be allowed to enter the plate-frame filter press 1101, and the leachate is filtered by the plate-frame filter press 1101 to separate the residue from the leachate. The leachate is transported to the decomposition tank 12 by the water pump 1103, and then the decomposition plate 15 is installed and placed between the two L-shaped blocks 604. Then, the electric push rod 601 is started, and the electric push rod 601 controls the vertical moving block 602 to move upward. When the vertical moving block 602 moves upward, the vertical moving block 602 moves upward.
