Description

Technical Field

[0001] This utility model relates to the field of lithium ore beneficiation technology, and in particular to an online adjustable device for heavy medium separation of lithium ore. Background Technology

[0002] The lithium ore heavy media separation density adjustable online device is a specialized equipment for lithium ore separation. By adjusting the density of the heavy media suspension, it achieves effective separation of lithium ore. The device has an automatic adjustment function, which can adjust the density value of the heavy media suspension in real time according to factors such as fluctuations in the amount of coal fed into the process and disturbances in the media recovery process, so as to ensure the stability of separation effect and product quality.

[0003] A density control device for heavy medium separation and heavy suspension can be referred to in existing literature (CN216678595U). The reference responds to the density detection signals of the first density meter and the second density meter, and controls the opening and closing of the water pump and several electrically controlled valves, so that the density of the heavy suspension in the qualified medium tank can be easily and accurately controlled when the decrease is small.

[0004] In existing technologies, density is often monitored in real time using a densitometer inside the qualified container. When the density needs to be increased, additional weight is added; when the density needs to be decreased, water is added to stabilize the density of the heavy medium suspension. However, temperature changes during the actual separation process can also affect the density of the heavy medium suspension. The aforementioned literature only adjusts the density by adjusting the liquid composition. Furthermore, pumping is often used when injecting the heavy medium suspension or water into the qualified container, with the pipeline connected to the qualified container. Due to the small spray range, the liquid is difficult to mix quickly when injected through the pipeline. Therefore, an online adjustable density device for lithium ore heavy medium separation with temperature control function is designed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an online adjustable density separation device for lithium ore heavy media. This invention involves installing multiple heating tubes inside a qualified container and a cooling fan at the top of the container. The combined use of the heating tubes and the cooling fan controls the temperature of the heavy media suspension within the qualified container, maintaining density stability. Simultaneously, during the process of pumping the heavy media suspension or water into the qualified container, the stirring rod, while agitating the mixture, can eject the heavy media suspension or water through the outlet, resulting in a more uniform distribution and improved mixing efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lithium ore heavy medium separation density adjustable online device includes: a qualified barrel and a guide plate. The qualified barrel has a heating tank inside, and multiple heating tubes are distributed in a ring in the heating tank. A cold air fan is fixedly installed above the qualified barrel by two brackets. A stirring rod is rotatably connected inside the guide plate. A transmission wheel is integrally connected to the bottom of the stirring rod. The stirring rod and the transmission wheel are hollow inside and communicate with each other. Multiple liquid outlets are opened at the bottom of the outer blades of the stirring rod. A liquid inlet is opened at the bottom of the transmission wheel. A connecting pipe is connected to the upper center of the guide plate and is rotatably connected to the inside of the liquid inlet.

[0008] The present invention is further configured such that a drive motor is fixedly installed on the right side of the qualified barrel, and a solid transmission wheel is fixedly connected to the output end of the drive motor.

[0009] The present invention is further configured such that both of the transmission wheels are narrow in the middle and wide at both ends, and the two transmission wheels are connected by a transmission belt, with the transmission belt being sleeved on the outside of the narrower middle part of the transmission wheel.

[0010] The present invention is further configured such that the inside of the guide plate is hollow, and the upper two sides of the guide plate are integrally connected with connecting blocks, and the two connecting blocks are simultaneously fixed to the qualified bucket above.

[0011] The present invention is further configured such that a bearing is embedded and fixed at the bottom of the qualified barrel, and the stirring rod is fixed in the inner ring of the bearing.

[0012] The present invention is further configured such that a density meter and a thermometer are installed inside the qualified barrel, and both the density meter and the thermometer are connected to an external PLC controller.

[0013] The present invention is further configured to include: a heavy medium suspension storage tank, a water tank, and two pumps. One pump connects the heavy medium suspension storage tank to one side of the feed tray via a pipeline, and the other pump connects the water tank to the other side of the feed tray via a pipeline.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. During use, the lithium ore heavy medium separation density online adjustable device can deliver the heavy medium suspension or water pump to the qualified tank for density adjustment in the traditional way. At the same time, the temperature can be adjusted by the cold air fan and the heating tube inside the qualified tank. The thermometer inside the qualified tank can monitor the internal liquid temperature in real time and transmit it to the external controller. Temperature control ensures that the temperature of the heavy medium suspension is within a suitable range, reducing the impact of temperature on density.

[0016] 2. In the process of injecting heavy medium suspension or water, the lithium ore heavy medium separation density adjustable device guides the heavy medium suspension or water to the guide plate by pumping, then guides it to the stirring rod through the guide plate, and finally discharges it through the liquid outlet at the bottom of the stirring rod blades. This allows the liquid to be injected simultaneously during the stirring process, increasing the diffusion range of the liquid injection and further improving the mixing effect.

[0027] Reference Figure 1-5 A lithium ore heavy medium separation density adjustable online device includes: a qualified tank 1, a heavy medium suspension storage tank 2, a water tank 3, and two liquid pumps 6. It also includes a guide plate 4, which is fixed to the bottom of the qualified tank 1. The inlets of the two liquid pumps 6 are connected to the heavy medium suspension storage tank 2 and the water tank 3 through pipelines, and the outlets of the two liquid pumps 6 are connected to the guide plate 4 through pipelines.

[0028] During the density adjustment process, when it is necessary to increase the internal density of qualified container 1, the concentrated heavy medium suspension inside the heavy medium suspension storage container 2 is injected into qualified container 1 by the operation of the liquid pump 6; when it is necessary to decrease the internal density of qualified container 1, water is injected into qualified container 1 for dilution by the operation of the liquid pump 6.

[0029] A hydrometer 19 is fixedly installed inside the qualified container 1. The density of the liquid is detected in real time by the hydrometer 19, and the detection signal is transmitted to the external controller.

[0030] Therefore, density adjustment is achieved by adding weight and water.

[0031] Specifically, such as Figure 1-2 As shown, brackets 7 are welded on both sides of the qualified barrel 1, and a cooler 8 is fixedly installed between the two brackets 7, with the air outlet of the cooler 8 facing the qualified barrel 1.

[0032] Furthermore, such as Figure 5 As shown, a heating groove 17 is provided inside the qualified barrel 1. Several heating tubes 18 are installed in the heating groove 17 in a ring at equal intervals. The inner wall of the qualified barrel 1 is made of heat-conducting metal.

[0033] Furthermore, a thermometer 20 is installed inside the qualified container 1. The thermometer 20 monitors the liquid inside in real time, and the monitoring signal is transmitted to an external controller.

[0034] In this embodiment, by observing the real-time temperature data of the external controller, the liquid inside the qualified container 1 is cooled or heated by turning on the air cooler 8 or the heating tube 18, thereby adjusting the temperature and reducing the impact of temperature changes on the density of the heavy medium suspension.

[0035] Specifically, such as Figure 4-5 As shown, a bearing 21 is embedded and fixed at the bottom of the qualified bucket 1, and a stirring rod 5 is fixed in the inner ring of the bearing 21.

[0036] Furthermore, a drive motor 10 is fixedly installed on the right side of the qualified barrel 1, and the output end of the drive motor 10 is connected to a... Figure 4 The transmission wheel 9 shown is solid and has no openings.

[0037] Furthermore, such as Figure 4 As shown, a drive wheel 9 is connected to the bottom of the stirring rod 5. Both the stirring rod 5 and the drive wheel 9 are hollow, and an inlet 16 is provided at the bottom of the drive wheel 9.

[0038] Furthermore, both drive wheels 9 are designed to be narrow in the middle and wide at both ends. The two drive wheels 9 are connected by a drive belt 11. This design can effectively limit the drive belt 11 and prevent it from dislodging.

[0039] In this embodiment, the solid transmission wheel 9 is driven to rotate by the operation of the drive motor 10, and the hollow transmission wheel 9 is driven to rotate by the transmission belt 11, thereby driving the stirring rod 5 above to rotate inside the qualified barrel 1.

[0040] Specifically, such as Figure 3 As shown, the top of the guide plate 4 is fixed to the bottom of the qualified barrel 1 by two connecting blocks 12, and a connecting pipe 13 is connected to the middle of the top of the guide plate 4. The guide plate 4 is hollow inside, and the connecting pipe 13 is rotatably connected to the liquid inlet 16.

[0041] Furthermore, liquid outlets 15 are provided at the bottom of the blades 14 on the outer side of the stirring rod 5.

[0042] In this embodiment, the heavy medium suspension or water can be first introduced into the guide plate 4 by the operation of the liquid pump 6, then into the hollow drive wheel 9, then into the hollow stirring rod 5, and finally diffused out through the liquid outlet 15 on the surface of the blade 14, thereby improving the mixing effect.

[0043] This allows the stirring rod 5 to inject liquid during the stirring process.

[0044] Working principle: When using this utility model, the density of the heavy medium suspension or water can be adjusted by pumping it into the qualified tank 1 in a conventional manner. At the same time, the temperature can be adjusted by the air cooler 8 and the heating tube 18 inside the qualified tank 1. The thermometer 20 inside the qualified tank 1 can monitor the internal liquid temperature in real time and transmit it to the external controller. Temperature control ensures that the temperature of the heavy medium suspension is within a suitable range, reducing the impact of temperature on density. During the injection of heavy medium suspension or water, the heavy medium suspension or water is pumped into the guide plate 4, then guided into the stirring rod 5, and finally discharged through the liquid outlet 15 at the bottom of the blade 14 of the stirring rod 5. This allows the stirring rod 5 to inject liquid simultaneously during the stirring process, increasing the diffusion range of the liquid injection and further improving the mixing effect.
