Description

Technical Field

[0001] This utility model relates to the field of hydrometallurgical technology, and more specifically, to a metallurgical hydrometallurgical leaching apparatus. Background Technology

[0002] Hydrometallurgy is a method in which ores, mineral concentrates, or other raw materials are contacted with aqueous solutions or other liquid phases. Through chemical reactions, the useful metals contained in the raw materials are transferred into the liquid phase. The various useful metals 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, liquid-solid separation, solution purification, metal extraction from the solution, and wastewater treatment.

[0003] A hydrometallurgical leaching device with a liquid level alarm function is disclosed in Chinese Patent Publication No. CN212721661U. The device includes a leaching tank, an end cap on top of the tank, a movable frame on top of the end cap, a top plate on top of the movable frame, an alarm fixedly connected to the top of the top plate, a control switch at the bottom of the top plate, sliding plates fixedly connected to both sides of the inner wall of the movable frame, a lifting plate slidably connected between opposite sides of the two sliding plates, a touch block on top of the lifting plate, a clamping assembly at the bottom of the lifting plate, a support rod clamped inside the clamping assembly, the bottom end of the support rod penetrating the leaching tank and extending into the interior of the leaching tank, and an air bladder at the end of the support rod extending into the interior of the leaching tank.

[0004] In the aforementioned device, an airbag comes into contact with the solution inside the leaching tank. As the liquid level rises, the airbag moves upward, which in turn moves the sliding plate upward via the support rod. This plate then contacts the control switch via a touch block. When the control switch is touched, an alarm is activated. If the operator does not respond promptly, the liquid level inside the leaching tank will continue to rise, potentially causing liquid to overflow and resulting in losses. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 This utility model provides a technical solution:

[0031] A metallurgical hydrometallurgical leaching apparatus includes a cylindrical body 1. Several sets of support legs 7 are evenly installed at the bottom of the cylindrical body 1. A feed pipe 2 and an alarm component 3 are respectively installed at the top of the cylindrical body 1. A switch component 4 and a buffer component 9 are respectively installed on the side wall of the cylindrical body 1. A filter plate 10 is installed on the inner wall at the lower end of the cylindrical body 1. A discharge component 5 and a stirring component 6 are respectively installed at the bottom of the cylindrical body 1. The stirring component 6 is connected to the filter plate 10. The alarm component 3 is respectively connected to a buffer component 12 and a linkage component 11.

[0032] Furthermore, the alarm component 3 includes a transmission rod 32, which is slidably connected to the top of the cylinder 1. A float 31 is installed at the bottom of the transmission rod 32, and the upper end of the transmission rod 32 passes through the top of the cylinder 1. A second sensor block 36 is installed at the top of the transmission rod 32. A housing 35 is installed at the top of the cylinder 1, and a first sensor block 33 is installed at the top inside the housing 35. An alarm light 34 is installed at the top of the housing 35, and the alarm light 34 is electrically connected to the first sensor block 33. The outer wall of the float 31 is connected to the buffer component 12 and the linkage component 11. As the liquid inside the cylinder 1 increases, the float 31 rises, and the transmission rod 32 will drive the second sensor block 36 to contact the first sensor block 33, causing the alarm light 34 to sound an alarm to remind the staff.

[0033] Furthermore, the buffer assembly 9 includes a buffer cylinder 91, which is fixedly connected to the side wall of the cylinder body 1. An inlet pipe 93 is installed between the upper outer wall of the buffer cylinder 91 and the outer wall of the cylinder body 1, and an outlet pipe 92 is installed between the lower outer wall of the buffer cylinder 91 and the lower outer wall of the cylinder body 1. The outlet of the outlet pipe 92 is connected to the linkage assembly 11. When the liquid level inside the cylinder body 1 rises to the inlet of the inlet pipe 93, the liquid will automatically flow into the buffer cylinder 91. At the same time, the float 31 drives the linkage assembly 11 to move upward, thereby opening the inlet of the inlet pipe 93, so that the liquid inside the buffer cylinder 91 can flow back into the cylinder body 1.

[0034] Furthermore, the linkage component 11 includes slide rails 113. Two sets of slide rails 113 are respectively fixed on the inner walls of the cylinder 1 on both sides of the liquid inlet of the liquid inlet pipe 93. Baffles 112 are inserted and connected to the inner walls of both sets of slide rails 113. A connecting rod 111 is connected between the top of the baffle 112 and the float 31. The side wall of the baffle 112 is in close contact with the liquid inlet of the liquid inlet pipe 93. During the upward movement of the float 31, the connecting rod 111 will pull the baffle 112 away from the liquid inlet of the liquid inlet pipe 93, so that the liquid inside the buffer cylinder 91 flows back into the cylinder 1.

[0035] Furthermore, the stirring assembly 6 includes a motor 61, which is fixedly connected to the bottom of the cylinder 1. The output end of the motor 61 passes through the cylinder 1 and the filter plate 10. A stirring blade 63 is installed on the upper outer wall of the output end of the motor 61, and a turbine fan 62 is installed on the lower outer wall of the output end of the motor 61. When the output end of the motor 61 rotates, the turbine fan 62 will drive the liquid to rotate continuously, and the stirring blade 63 will continuously agitate the mineral sand to prevent the mineral sand adhering to the filter plate 10 from not being effectively reacted.

[0036] Furthermore, the buffer assembly 12 includes a cylinder 122, and several sets of cylinders 122 are fixedly connected to the outer wall of the float 31. A round rod 121 is slidably connected to the inner wall of the other end of each set of cylinders 122. A spring 123 is installed between the end of the round rod 121 inside the cylinder 122 and the inner wall of the cylinder 122. When the turbine fan 62 stirs the liquid continuously, the float 31 on the liquid surface will shake continuously. When the round rod 121 hits the inner wall of the cylinder 1, it is compressed inside the cylinder 122 in conjunction with the spring 123, thereby offsetting part of the impact force and ensuring that the float 31 does not shake excessively.

[0037] Furthermore, the switch assembly 4 includes a side door 41, which is installed on the lower side wall of the cylinder 1. A handle 42 is installed on the outer wall of the side door 41. The connection of the side door 41 is sealed, and the bottom of the side door 41 is flush with the top of the filter plate 10. Pulling the handle 42 opens the side door 41, which makes it easy to clean the mineral sand residue on the filter plate 10.

[0038] Furthermore, the discharge assembly 5 includes a discharge pipe 51, which is fixedly connected to the bottom of the cylinder 1. A valve 52 is installed on the outer wall of the discharge pipe 51. The valve 52 can be an electromagnetic valve or a manually operated valve.

[0039] Furthermore, a control device 8 is installed on the outer wall of the cylinder 1. The control device 8 is electrically connected to the motor 61 and is a PLC controller.

[0040] Furthermore, both the connecting rod 111 and the baffle 112 are made of plastic.

[0041] Working principle: The solution or ore is injected into the cylinder 1 through the feed pipe 2 for wet metallurgical leaching. Then, the stirring component 6 continuously stirs and mixes the solution or ore inside the cylinder 1 to accelerate the reaction. As the amount of solution or ore increases, the liquid level inside the cylinder 1 will gradually rise, causing the alarm component 3 to sound an alarm. At the same time, the linkage component 11 will open the switch between the linkage component 11 and the buffer component 9, so that the excess liquid will automatically flow into the buffer component 9 and then flow back into the cylinder 1, preventing the liquid inside the cylinder 1 from overflowing. The cylinder 1 can be opened by the switch component 4 to facilitate the discharge of residues on the filter plate 10 from the cylinder 1.
