Description

Technical Field

[0001] This utility model relates to the field of gold ore oxidation treatment technology, specifically a bio-oxidation device for gold ore treatment. Background Technology

[0002] In the gold ore processing, bio-oxidation devices play a crucial role. However, traditional bio-oxidation devices for gold ore processing suffer from a series of problems. First, the maintenance and cleaning of the devices are difficult. Aeration pipes are usually fixed at the bottom of the device, and if the aeration pipes or stirring components malfunction, the repair process is cumbersome and time-consuming, affecting the production schedule. Second, the existing devices have a single stirring function, which cannot effectively solve the foaming problem that occurs during the reaction process. Excessive foam not only hinders gas exchange but may also cause the reaction liquid to overflow, affecting production safety and environmental hygiene. With the increase in gold mining volume and the increasing requirements for gold ore processing efficiency and quality, it is urgent to develop a high-efficiency, stable, and easy-to-maintain bio-oxidation device for gold ore processing. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a bio-oxidation device for gold ore processing, which solves the problem of inconvenient maintenance of existing devices.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a bio-oxidation device for gold ore processing, comprising a shell, the top of which is an open structure, and a drain pipe at the bottom. A support is provided on the side wall of the shell, and a top plate is mounted on the support.

[0009] Preferably, the drain pipe is equipped with a valve.

[0010] Beneficial effects

[0011] This utility model provides a bio-oxidation device for gold ore processing, which has the following beneficial effects:

[0012] The first motor drives the screw to rotate, causing the slider screwed to the screw to move up and down in the groove, thereby lifting the pipe frame and the annular aeration pipe to the top of the device. This allows for convenient maintenance of the annular aeration pipe without requiring personnel to enter the device. The lifting design allows for flexible adjustment of the aeration pipe position according to different stages of gold ore processing and the depth of the reaction liquid, ensuring uniform and sufficient aeration. In the initial stage of the reaction, the aeration pipe can be adjusted closer to the bottom to provide sufficient oxygen for the microorganisms; as the reaction progresses, the position of the aeration pipe is gradually raised to ensure oxygen supply throughout the reaction area, improving oxygen utilization, enhancing the biological oxidation effect, and increasing the efficiency of gold ore processing.

[0013] In the stirring assembly, the second motor drives the main shaft to rotate. The spiral stirring blades at the bottom of the main shaft can longitudinally stir the reaction liquid, promoting the full mixing of gold ore particles, microorganisms, and the reaction liquid. At the same time, the auxiliary stirring structure on the turntable, through the meshing of the gear ring on the outer wall of the fixed ring and the gear on the rotating shaft, causes the rotating shaft to drive the frame and defoaming mechanism to rotate, which in turn stirs the reaction liquid laterally. The defoaming net in the frame can effectively break the foam generated during the reaction, preventing the foam from hindering gas exchange and causing the reaction liquid to overflow, ensuring the smooth progress of the bio-oxidation reaction, and improving the stability and safety of the device operation.

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.

[0018] Please see Figure 1-2 This utility model provides a technical solution: a bio-oxidation device for gold ore processing, comprising a shell 1, the top of the shell 1 being an open structure, a drain pipe 2 at the bottom, a support 3 on the side wall of the shell 1, a top plate 4 on the support 3, a first motor 5 on the top plate 4, a screw 6 mounted on the drive end of the first motor 5, the lower end of the screw 6 being rotatably connected to the lower inner wall of the shell 1, a longitudinally arranged sliding groove 7 on the inner wall of the shell 1, a slider 8 screwed to the screw 6 in the sliding groove 7, a pipe frame 9 fixedly mounted on one end of the slider 8, an annular aeration pipe 10 clamped in the pipe frame 9, an aeration head on the annular aeration pipe 10, an air inlet hose 11 connected to the end of the annular aeration pipe 10 away from the pipe frame 9, one end of the air inlet hose 11 extending upward to the outside of the shell 1, and a stirring assembly inside the shell 1.

[0019] By adopting the above technical solution, in the gold ore processing, the gas source is turned on and aeration is carried out through the annular aeration pipe 10, and the mixture is stirred by the stirring component. When it is necessary to adjust the height position of the annular aeration pipe 10, the first motor 5 is started, and the screw 6 rotates to drive the slider 8 and the annular aeration pipe 10 to rise and fall, so as to meet the needs of different working conditions.

[0020] In this embodiment, the stirring assembly includes a second motor 12 mounted on the top plate 4. The driving end of the second motor 12 is equipped with a main shaft 13 extending into the housing 1. The bottom of the main shaft 13 is provided with a plurality of spiral stirring blades 14 along the axial direction. A turntable 15 is fixedly mounted on the upper end of the main shaft 13. An auxiliary stirring structure is provided on the turntable 15.

[0021] By adopting the above technical solution, the second motor 12 is started, which drives the main shaft 13 and the spiral stirring blade 14 to rotate. At the same time, the main shaft 13 drives the turntable 15 to rotate. The spiral stirring blade 14 in the stirring assembly realizes the longitudinal stirring of the reaction liquid, promotes the full mixing of gold ore particles, microorganisms and reaction liquid, creates a good mixing environment for the bio-oxidation reaction, and further improves the reaction effect.

[0022] In this embodiment, the auxiliary stirring structure includes a plurality of rotating shafts 16 rotatably mounted on the lower wall of the turntable 15. The plurality of rotating shafts 16 are arranged in a circular array on the turntable 15 with the main shaft 13 as the center. A plurality of frames 17 are arranged axially on the side wall of the rotating shaft 16. A defoaming mechanism is provided in the frame 17. A gear 18 is installed on the upper end of the rotating shaft 16. A fixing ring 19 fitted on the outside of the main shaft 13 is fixedly provided on the lower wall of the top plate 4. A gear ring 20 that meshes with the gear 18 is provided on the outer wall of the fixing ring 19.

[0023] By adopting the above technical solution, when the turntable 15 rotates, the gear 18 on the rotating shaft 16 meshes with the gear ring 20 on the outer wall of the fixed ring 19, causing the rotating shaft 16 to drive the frame 17 and the defoaming mechanism to rotate. At the same time, the turntable 15 will also drive the rotating shaft 16 to rotate around the main shaft 13, realizing the lateral stirring of the reaction liquid. Meanwhile, the defoaming mechanism can effectively break the foam, prevent the foam from having an adverse effect on the reaction, ensure the smooth progress of the biological oxidation reaction, and improve the stability of the device operation.

[0024] In this embodiment, the defoaming mechanism includes a slot within a frame 17, a defoaming net 21 is inserted into the slot, a pull plate 22 is fixedly provided at the upper end of the defoaming net 21, and the pull plate 22 is connected to the frame 17 by bolts.

[0025] By adopting the above technical solution, when the defoaming net 21 needs to be cleaned or replaced, the bolts on the pull plate 22 can be loosened and the defoaming net 21 can be taken out of the slot. The detachable design allows for timely cleaning or replacement of the defoaming net 21, ensuring the defoaming effect and improving the maintainability of the device.

[0026] In this embodiment, the air intake hose 11 is further configured to have a corrugated pipe structure.

[0027] By adopting the above technical solution, the corrugated structure of the air inlet hose 11 ensures that gas can be delivered normally when the position of the annular aeration pipe 10 changes, and also has good flexibility.

[0028] In this embodiment, the drain pipe 2 is further configured to have a valve.

[0029] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0030] Example: In use, the reaction liquid and other materials are added to the shell 1 in proportion. The air inlet hose 11 is connected to the aerator. The gas is evenly dispersed into the reaction liquid through the aeration head on the annular aeration pipe 10 to provide oxygen for the biological oxidation reaction. The second motor 12 is started, which drives the main shaft 13 and the spiral stirring blades 14 to rotate, longitudinally stirring the reaction liquid. At the same time, the main shaft 13 drives the turntable 15 to rotate. The gear 18 on the rotating shaft 16 of the turntable 15 meshes with the gear ring 20 on the outer wall of the fixed ring 19, so that the rotating shaft 16 drives the frame 17 and the aerator. The foaming mechanism rotates to stir the reaction liquid laterally and break the foam. During the reaction, observe the reaction situation and adjust the position of the aeration pipe as needed by the first motor 5. When adjustment is needed, start the first motor 5, which drives the screw 6 to rotate. Adjust the position of the slider 8 and the annular aeration pipe 10 according to the reaction requirements. After the reaction is completed, turn off the air source and motor, open the valve on the drain pipe 2, and discharge the liquid after the reaction. If the defoaming net 21 is found to be blocked or damaged, loosen the bolts on the pull plate 22, remove the defoaming net 21, and clean or replace it.
