Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for whole mud cyanidation, specifically a whole mud cyanidation aeration device. Background Technology

[0002] In whole-sludge cyanidation, oxygen is the key oxidant for gold dissolution. Aeration can provide sufficient oxygen to enable cyaniding agents (such as sodium cyanide) to effectively oxidize gold particles, forming soluble gold-cyanide complexes. Furthermore, proper oxygen supply can reduce side reactions between cyanide and impurities such as sulfides, thereby reducing cyanide consumption and environmental pollution risks.

[0003] However, existing methods primarily involve filling the tank with gas via gas pipes. This results in low uniformity of gas filling, affecting the leaching parameters of cyanide treatment, and significantly impacting the leaching rate and recovery rate of gold and silver. Furthermore, the separate gas supply pipes are prone to blockage, which further exacerbates the uneven distribution of oxygen during filling.

[0004] In view of this, we propose a whole-sludge cyanidation aeration device. Utility Model Content

[0005] The purpose of this utility model is to provide a whole-sludge cyanidation aeration device, which solves the problems mentioned in the background art.

[0027] 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.

[0028] Please see Figures 1-5 A whole-slurry cyanidation aeration device includes a tank 1 for cyanidating and dissolving gold in gold ore slurry. A rotating shaft 2 is rotatably installed inside the tank 1, and multiple stirring blades 3 are fixedly installed on the surface of the rotating shaft 2. The stirring blades 3 are arranged in a circular array to stir the slurry, thereby improving the cyanidation effect. Furthermore, multiple uniformly distributed through holes 31 are simultaneously formed on the surface of the stirring blades 3, which can more evenly cut oxygen bubbles.

[0029] An air inlet pipe 4 is fixedly installed at the bottom of the tank 1 to supply oxygen into the tank 1 for cyanide leaching. An air supply mechanism 5 is provided between the tank 1 and the rotating shaft 2 to ensure uniform oxygen distribution and improve the reaction efficiency of cyanide leaching. An anti-clogging mechanism 6 is provided on the rotating shaft 2 to prevent impurities from accumulating on the air inlet pipe 4 and causing blockage.

[0030] Please see Figures 2-4 The inflation mechanism 5 includes multiple inflation blades 51, which are fixedly installed on the bottom surface of the rotating shaft 2. The inflation blades 51 are connected to the air inlet pipe 4, allowing oxygen to be injected into them through the inlet pipe 4. The multiple inflation blades 51 are arranged in a circular array and have an arc-shaped structure, making them more stable when rotating with the rotating shaft 2. This reduces the impact loss of the slurry on the inflation blades 51 and effectively improves their service life. Multiple inflation holes 52 are provided at the upper end of each inflation blade 51, arranged in an array. This allows oxygen to be evenly discharged upwards through the inflation holes 52, and then the stirring blades 3 provide lateral shearing force to cut the oxygen bubbles, resulting in a more uniform oxygen distribution. A rotating fan 53 is rotatably installed inside the inflation holes 52, allowing oxygen to enter the tank 1 through the rotating fan 53, creating a spiral flow for faster distribution.

[0031] A drain block 54 is slidably installed at one end of the air-filling blade 51. The drain block 54 and the air-filling blade 51 are also elastically connected by a sleeve spring. This can prevent the slurry from directly contacting the spring, which would reduce the service life of the spring. It can also prevent the slurry from rushing into the connection between the air-filling blade 51 and the drain block 54, which would affect the operation of the drain block 54.

[0032] The rotating shaft 2 drives the stirring blade 3 and the aeration blade 51 to rotate synchronously. Oxygen enters the stirring blade 3 through the air inlet pipe 4, and then spirals into the tank 1 through the air inlet 52 and the rotating fan 53. When the oxygen rises, it is cut into finer bubbles by the stirring blade 3, which makes it easier to distribute the oxygen evenly and thus improve the efficiency of cyanide leaching.

[0033] When the air-filled blade 51 rotates, it generates centrifugal force, causing the sludge discharge block 54 to move away from the air-filled blade 51. The port of the air-filled blade 51 opens, and the heavier slurry inside the air-filled blade 51 is thrown out by the centrifugal force to avoid blockage.

[0034] Please see Figure 5 The anti-blocking mechanism 6 includes a protective block 66, which is slidably installed inside the rotating shaft 2. The surface of the protective block 66 is in contact with one end opening of the inflation blade 51, and the bottom end of the protective block 66 is in contact with the air inlet of the air inlet pipe 4. The protective block 66 plays a role in blocking the air inlet pipe 4, preventing slurry from entering the air inlet pipe 4 through the inflation hole 52 and accumulating, causing blockage.

[0035] The anti-blocking mechanism 6 also includes multiple sliding seats 61, which are fixedly installed on the surface of the rotating shaft 2. The sliding seats 61 are located between the stirring blade 3 and the air-filling blade 51, and the multiple sliding seats 61 are arranged in a circular array. This allows the sliding seats 61 to rotate synchronously with the rotating shaft 2. A sliding groove 62 is provided inside the sliding seat 61, which is connected to the air intake pipe 4. A counterweight ball 63 is slidably installed in the sliding groove 62. The counterweight ball 63 is fixedly connected to the protective block 66 by a connecting rope 65. When not in operation, the protective block 66 can drive the counterweight ball 63 to move along the sliding groove 62 under the action of gravity, so that the protective block 66 can play a protective role for the air intake pipe 4.

[0036] When the rotating shaft 2 rotates, the rotating shaft 2 drives the sliding seat 61 to rotate, generating centrifugal force. The centrifugal force causes the counterweight ball 63 to move along the sliding groove 62. When the counterweight ball 63 moves, it drives the protective block 66 to move upward along the inner wall of the rotating shaft 2 through the connecting rope 65. The upward movement of the protective block 66 connects the air inlet pipe 4 and the air filling blade 51, so that oxygen can enter the tank 1.

[0037] A baffle 64 is fixedly installed at one end of the sliding groove 62 near the rotating shaft 2. The baffle 64 has a centrally located circular hole with an arc-shaped surface. The connecting rope 65 passes through this hole. The arc-shaped surface of the hole reduces friction between the baffle 64 and the connecting rope 65, thus reducing wear and extending its service life. Furthermore, the baffle 64 also acts as a barrier to prevent the counterweight ball 63 from detaching from the sliding groove 62.

[0038] A whole-sludge cyanidation aeration device, the working principle of which is as follows:

[0039] When the rotating shaft 2 rotates, it drives the sliding seat 61 to rotate, generating centrifugal force. This centrifugal force causes the counterweight ball 63 to move along the sliding groove 62. As the counterweight ball 63 moves, it drives the protective block 66 to move upward along the inner wall of the rotating shaft 2 via the connecting rope 65. The upward movement of the protective block 66 connects the air inlet pipe 4 and the air filling blade 51. At this time, oxygen is introduced, and the air filling blade 51 is rotating, preventing slurry from entering the air inlet pipe 4 through the air filling hole 52. When the work is finished, the rotating shaft 2 stops rotating, the centrifugal force gradually disappears, and the weight of the protective block 66 seals and protects the air inlet pipe 4, preventing slurry from entering and accumulating inside the air inlet pipe 4, which could cause blockage.

[0040] After the air inlet pipe 4 and the air filling blade 51 are connected, the rotating shaft 2 rotates, causing the stirring blade 3 and the air filling blade 51 to rotate synchronously. Oxygen enters the stirring blade 3 through the air inlet pipe 4, and then spirals into the tank 1 through the air filling hole 52 and the rotating fan 53. When the oxygen rises, it will be cut into finer bubbles by the stirring blade 3, which makes it easier to uniformly distribute the oxygen and thus improve the efficiency of cyanide leaching.
