Description

Technical Field

[0001] This utility model relates to the field of hydrometallurgical technology, specifically to a water supply device for hydrometallurgical refining. Background Technology

[0002] Hydrometallurgy is a method of metallurgy in which ores, mineral concentrates, or other raw materials are contacted with aqueous solutions or other liquid phases. Through chemical reactions, the non-ferrous metals contained in the raw materials are transferred to the liquid phase. The various valuable metals contained in the liquid phase are then separated and concentrated, and finally recovered as metals or other compounds. It mainly includes unit operations such as leaching, solid-liquid separation, solution purification, metal extraction from the solution, and wastewater treatment. Hydrometallurgy utilizes leaching agents to dissolve valuable metal components in ores, concentrates, roasted sand, and other materials in solution or to precipitate them as a new solid phase, thereby achieving metal separation, concentration, and extraction. Because this metallurgical process is mostly carried out in aqueous solutions, it is called hydrometallurgy.

[0003] The leaching solutions used in hydrometallurgy can be classified into acid leaching, alkali leaching, and salt leaching depending on the leaching agent. Currently, liquid pumps are generally used to transport the leaching solution. However, the solution comes into contact with the impeller inside the pump, which can lead to corrosion of the impeller and affect the service life of the pump. Furthermore, when replacing the impeller, since it is directly fixed to the drive shaft, which is connected to the housing through bearings, the bearings at both ends need to be removed before the impeller can be replaced, making the operation cumbersome.

[0024] Please see Figure 1 - Figure 4 In this embodiment, a water supply device for hydrometallurgical refining includes: a base plate 1, a housing 11 fixedly installed on the top of the base plate 1, connecting pipes 12 inserted through the left and right sides of the housing 11, a connecting bearing 13 fitted inside the housing 11, a drive shaft 14 inserted through the top of the housing 11, a limiting shaft 15 movably installed below the housing 11, gears 16 inserted through the outer sides of the drive shaft 14 and the limiting shaft 15, a sealing gasket 17 movably installed on the front side of the housing 11, an end cover 18 fixedly installed at the front end of the housing 11, a connecting bolt 19 inserted through the front side of the end cover 18, a pressure bearing 110 fitted inside the end cover 18, a limiting block 111 fixedly installed on the front side of the pressure bearing 110, a support frame 112 fixedly installed on the top of the base plate 1, a motor 113 fixedly installed on the top of the support frame 112, and a positioning pin 114 inserted through the end of the rotating shaft of the motor 113.

[0025] The front end of the outer shell 11 is flush with the front end of the base plate 1. A horizontal opening, identical in size to the connecting bearing 13, is provided on the upper part of the outer shell 11. The drive shaft 14 is inserted into the opening on the upper part of the outer shell 11 via the connecting bearing 13, forming a rotatable connection with the outer shell 11. A cylindrical recess, fitting into the connecting bearing 13, is provided on the rear side of the inner cavity of the outer shell 11. The limiting shaft 15 is installed in the recessed structure of the outer shell 11 via the connecting bearing 13, forming a rotatable connection with the outer shell 11. A protrusion of the same size is provided on the outer sides of the drive shaft 14 and the limiting shaft 15. A protrusion, identical in size to the drive shaft 14 and the limiting shaft 15, is provided at the center of the gear 16. The gear 16 is slidably connected to the drive shaft 14 and the limiting shaft 15 through the fitting opening. The surface of the sealing gasket 17 is provided with an opening structure that fits into the connecting bolt 19. The connecting bolt 19 passes through the end of the end cover 18 and is located inside the outer shell 11. The end cover 18 is fixedly connected to the outer shell 11 through the connecting bolt 19. One end of the limiting block 111 is provided with a recess that fits into the front end protrusion of the drive shaft 14 and the limiting shaft 15. The limiting block 111 is slidably connected to the drive shaft 14 and the limiting shaft 15 through the pressure bearing 110. The end of the motor 113 shaft is fixedly connected to the drive shaft 14 through the positioning pin 114.

[0026] Specifically, the base plate 1 restricts the position of the housing 11. The inner cavity of the housing 11 is closed after the end cover 18 is installed, so that the gear 16 can pump out the leachate. The connecting pipe 12 is located on both sides of the housing 11 to facilitate the connection between the housing 11 and the pipeline. The connecting bearing 13 facilitates the rotation of the drive shaft 14 and the limiting shaft 15. The position of the gear 16 is restricted by the protruding structure on the outside of the drive shaft 14 and the limiting shaft 15, so that the gears 16 are kept in a meshing state. The sealing gasket 17 can play a sealing role. The connecting bolt 19 can restrict the relative position between the housing 11 and the end cover 18. The drive shaft 14, the limiting shaft 15 and the gear 16 are made of 430A ferritic stainless steel. The pressure bearing 110 can... To facilitate a rotatable connection between the limiting block 111 and the end cap 18, the limiting block 111 can restrict the position of the ends of the drive shaft 14 and the limiting shaft 15, and the support frame 112 can restrict the position of the motor 113. The rotating shaft of the motor 113 is raised to be flush with the drive shaft 14 so that the rotating shaft of the motor 113 can be connected to the drive shaft 14. The position between the rotating shaft of the motor 113 and the drive shaft 14 is restricted by the positioning pin 114 so that the motor 113 can drive the drive shaft 14 to rotate. When the drive shaft 14 rotates, it will drive the gear 16 to rotate. The liquid on one side of the gear 16 will rotate around the center of the gear 16 under the drive of the gear 16 and move to the other side of the gear 16, thereby pumping out the liquid.

[0027] In use, the limiting block 111 is rotatably connected to the end cover 18 via the pressure bearing 110. One end of the limiting block 111 has a recess that engages with the protrusions at the front ends of the drive shaft 14 and the limiting shaft 15. The limiting block 111 is slidably connected to the drive shaft 14 and the limiting shaft 15. After removing the connecting bolt 19, the end cover 18 can be disassembled. The ends of the drive shaft 14 and the limiting shaft 15 can slide out of the limiting block 111. Since the center of the gear 16 has an opening that engages with the protrusions of the drive shaft 14 and the limiting shaft 15, and the gear 16 is slidably connected to the drive shaft 14 and the limiting shaft 15, When replacing gear 16, it can be removed from the outside of drive shaft 14 and limit shaft 15 by sliding. This method can ensure the positions of both ends of drive shaft 14 and limit shaft 15 while preventing the bearing structure from blocking the movement of gear 16 during removal, so as to facilitate the replacement of vulnerable parts. The surfaces of drive shaft, limit shaft and gear are coated with A ferritic stainless steel coating. The coating thickness of A ferritic stainless steel is 0.5mm and covers the surfaces of drive shaft, limit shaft and gear. It has good toughness and corrosion resistance to extend the service life of drive shaft 14, limit shaft 15 and gear 16.
