Description

Technical Field

[0001] The utility model relates to the technical field of aeration devices, in particular to an aeration device for efficient flotation of copper, lead and zinc. Background Art

[0002] Metals such as copper, lead, and zinc are usually found in sulfide ores, which contain metal minerals such as chalcopyrite (CuFeS2), galena (PbS), sphalerite (ZnS), etc. These metal minerals are usually coexisting with other useless minerals (gangue) and other possible metal minerals in their natural state. In order to extract these metals economically and efficiently, they need to be separated from the ores, and this process usually uses flotation.

[0003] At present, the main equipment in the flotation method is the pneumatic flotation machine, which mainly uses equipment such as blowers to suck air from the outside air and inject it directly into the flotation machine through pipes.

[0004] The equipment with the current announcement number CN208894409U discloses a flotation machine with a blower, including a flotation tank, a support frame is arranged across the upper part of the flotation tank, a stirring and frothing device and a scraping and frothing device are arranged on the support frame, the stirring and frothing device comprises a fixed seat, the fixed seat is rotatably connected with a stirring shaft, a first motor for driving the stirring shaft to rotate is also arranged on the support frame, a tubular central cylinder is connected to the lower end of the fixed seat, a pulp inlet bucket is arranged on the outer wall of the flotation tank, a pulp guide pipe is connected between the central cylinder and the pulp inlet bucket, an air inlet duct is arranged on the upper part of the central cylinder, the end of the air inlet duct is connected to the blower through a pipeline, an impeller is connected to the lower end of the stirring shaft, a locking bolt is arranged at the lower end of the stirring shaft, and when the locking bolt is locked with the stirring shaft, the locking bolt rotates coaxially with the stirring shaft, and an annular sleeve is arranged at the bottom of the flotation tank; the deformation of the stirring shaft during rotation can be avoided by the fixed seat and the annular sleeve, and the blower can make the area stirred by the impeller have sufficient air and slurry mixing.

[0005] However, the following problems still exist in the flotation machine with a blower:

[0006] At present, the blower and the flotation machine are often connected by a pipe. When air passes through the pipe for a long time, it is very likely that the moisture, acidic gas (such as sulfur dioxide SO2, hydrogen sulfide H2S, carbon dioxide CO2, etc.) in the air and the salt and chemicals in the dust can react with the metal of the pipe, causing corrosion, and may even eventually cause leakage or rupture. However, the current connection between the blower and the flotation machine is mostly a single pipe. When the pipe is corroded internally or cracked or broken due to other reasons, the pipe needs to be inspected and replaced, and the entire equipment needs to be shut down. This will not only affect the flotation of the material already in the flotation tank, but also reduce the overall flotation efficiency, which is very inconvenient. Utility Model Content

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] See also Figure 1-Figure 4, an aeration device for efficient flotation of copper, lead and zinc, comprising a blower body 1, the output end of the blower body 1 is fixedly connected and connected with a fixed pipe 2 by bolts, the other end of the fixed pipe 2 is fixedly connected and connected with a connecting pipe 3, the other end of the connecting pipe 3 is fixedly connected and connected with two shunt pipes 4, the other ends of the two shunt pipes 4 are both connected with replacement pipes 6, the other ends of the two replacement pipes 6 are connected with another group of shunt pipes 4, the other ends of the other group of two shunt pipes 4 are fixedly connected and connected with another connecting pipe 3, a sealing assembly is provided at the connection between the two shunt pipes 4 and the connecting pipe 3 near one end of the blower body 1, the other end of the sealing assembly is connected with a power mechanism, the other end of the power mechanism passes through the inner wall of the shunt pipe 4 and is connected to the outer wall of the connecting pipe 3, the inner walls of the two replacement pipes 6 are both connected with a monitoring mechanism, and the inner walls of the two shunt pipes 4 away from the blower body 1 are both provided with solenoid valves 7.

[0026] The aeration device for efficient flotation of copper, lead and zinc in the utility model is similar in structure to the existing aeration device for efficient flotation of copper, lead and zinc, such as a flotation machine with a blower disclosed in the patent with publication number CN208894409U. Figures 1 to 4 As shown, when the user supplies air to the inside of the flotation machine that is flotating metal minerals such as copper, lead, and zinc through the blower body 1, the power mechanism can be used to control the sealing component and the solenoid valve 7 to seal one of the replacement tubes 6, and then the air transported from the inside of the blower body 1 will be transported to the flotation machine from the other replacement tube 6. If during the air supply period, the monitoring mechanism located inside the replacement tube 6 detects that the replacement tube 6 has leakage, etc., after the machine is stopped, it is only necessary to quickly control the power mechanism to reverse through the external PLC controller, and at the same time, close the solenoid valve 7 corresponding to the damaged replacement tube 6, and open the solenoid valve 7 corresponding to the other replacement tube 6, and then the sealing component can be quickly reversed to the connection between the broken replacement tube 6 and the diversion tube 4, so that the inside of the broken replacement tube 6 can be sealed, and at this time, the air transported from the inside of the blower body 1 will continue to be transported to the flotation machine from the inside of the other normal replacement tube 6, so that the entire air supply mechanism can be put into operation again faster, and the flotation machine can continue to be supplied with air, so as not to affect the flotation efficiency.

[0027] Special mention should be made here:

[0028] 1. The external PLC controller is a prior art and will not be described in detail.

[0029] 2. Because the end of the replacement tube 6 away from the sealing component is provided with a solenoid valve 7, if the gas transported inside the replacement tube 6 is air or other gas harmless to the human body, there is no need to stop the machine, and the two replacement tubes 6 can be directly switched through the sealing component and the solenoid valve 7, without any specific limitation.

[0030] 3. If it is necessary to make two replacement pipes 6 work at the same time, it is only necessary to control the sealing assembly through the power mechanism to not seal the two diversion pipes 4.

[0031] Please refer to Figure 3 A rotating cavity 401 is formed on the inner wall of the connection between the two shunt pipes 4 and the connecting pipe 3 , and the sealing assembly and the power mechanism are both located in the rotating cavity 401 .

[0032] More specifically, by providing the rotating chamber 401, firstly, a storage and support point can be provided for the power mechanism and the sealing assembly; secondly, the external space occupied by the power mechanism and the sealing assembly can be reduced.

[0033] Please refer to Figure 3 The sealing assembly includes a rotating block 13 and a sealing block 14. The outer wall of the rotating block 13 is rotatably connected to the inner wall of the rotating chamber 401, and one end of the rotating block 13 located in the rotating chamber 401 is connected to the power mechanism. The side of the rotating block 13 away from the rotating chamber 401 is fixedly connected to one side of the sealing block 14. The outer wall of the sealing block 14 is slidably connected to the inner walls of the two shunt pipes 4, and the sizes are matched.

[0034] More specifically, when it is necessary to seal one of the shunt tubes 4, the power mechanism drives the rotating block 13 to rotate in the rotating chamber 401. After the rotating block 13 rotates, the sealing block 14 connected to the other side can be mobilized to rotate. When the sealing block 14 rotates, it will just block the inner wall of the shunt tube 4, and then the shunt tube 4 can be sealed, so that air can flow from the inside of the other replacement tube 6.

[0035] Please refer to Figure 3 The power mechanism includes a motor 10 and a transmission rod 12. The outer wall of the motor 10 is fixedly connected to the outer wall of the connecting tube 3. The output shaft of the motor 10 is fixedly connected to one end of the transmission rod 12. The other end of the transmission rod 12 passes through the shunt tube 4 and the rotating block 13, and is fixedly connected to the inner wall of the rotating block 13. The transmission rod 12 is rotatably connected to the penetration point of the shunt tube 4.

[0036] More specifically, when one of the shunt tubes 4 needs to be sealed, it is only necessary to turn on the switch of the motor 10 through the external PLC controller. After the motor 10 is started, the output shaft drives the transmission rod 12 to rotate. After the transmission rod 12 rotates, it can drive the rotating block 13 located in the rotating chamber 401 to rotate.

[0037] Please refer to Figure 4 The monitoring mechanism includes a support block 15 and a sensor 16 . One end of the support block 15 is fixedly connected to the inner wall of the replacement tube 6 , and the outer wall of the sensor 16 is fixedly connected to the inner wall of the other end of the support block 15 .

[0038] More specifically, when air circulates inside the replacement tube 6, it will contact the sensor 16 located in the support block 15, and the sensor 16 also monitors the circulating wind speed and other conditions in real time. When it detects that the circulating air is lower than the set standard, it immediately transmits an electrical signal to the external processor, and then quickly starts the motor 10 and the solenoid valve 7 through the external PLC controller to switch the replacement tube 6.

[0039] It should be particularly noted here that the sensor 16 can be a common wind speed sensor, or other sensors with the same monitoring effect, without specific limitation.

[0040] Please refer to Figure 1-Figure 4 One end of the four shunt tubes 4 is close to the replacement tube 6 , and flanges 5 are fixedly connected to both ends of the replacement tube 6 , and the flanges 5 of the shunt tubes 4 match the flanges 5 on the replacement tube 6 .

[0041] More specifically, by providing the flange 5 , it is more convenient to operate when installing and removing the replacement pipe 6 .

[0042] Please refer to Figure 1 and Figure 2 The outer walls of the two connecting pipes 3 are sleeved and fixedly connected with brackets 11, and the lower ends of the two brackets 11 are flush with the bottom surface of the blower body 1.

[0043] More specifically, by providing the bracket 11, it is possible to avoid the connecting pipe 3, the shunt pipe 4, the replacement pipe 6 and the like being too heavy and thus tilting downward.

[0044] Please refer to Figure 1 and Figure 2 , pressure gauges 8 are provided on both replacement pipes 6 .

[0045] More specifically, when the replacement tube 6 needs to be replaced, by providing the pressure gauge 8, the internal pressure of the replacement tube 6 can be known, thereby avoiding accidents during disassembly or maintenance.

[0046] Please refer to Figure 1 and Figure 2 , pressure relief valves 9 are provided on both replacement pipes 6 .

[0047] More specifically, although there may be cracks on the replacement tube 6 causing air leakage, the cracks may be small. After the sealing block 14 and the solenoid valve 7 seal the two ends of the replacement tube 6, the internal pressure of the replacement tube 6 may still be too high and the air leakage is slow. At this time, the pressure relief can be accelerated through the pressure relief valve 9 to speed up the replacement.

[0048] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
