[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] like Figure 1 to Figure 2 As shown, the present embodiment discloses a portable heavy medium floating and sinking test equipment, including a base box 11, on which an outer barrel 7 of the floating and sinking test device is arranged, a mesh filter 2 is arranged on the inner side of the outer barrel 7 of the floating and sinking test device, and an anti-splash protection device 1 is arranged on the top of the outer barrel 7 of the floating and sinking test device. The anti-splash protection device 1 is buckled on the barrel mouth of the outer barrel 7 of the floating and sinking test device. The anti-splash protection device 1 is used to prevent heavy medium and ore particles from flying out during the experiment, and can also prevent pollutants from falling into the floating and sinking test device to affect the test results.

[0031] A heavy medium recovery device 8 is provided at the bottom of the outer barrel 7 of the floating and sinking test device, and the heavy medium recovery device 8 is connected to the outer barrel 7 of the floating and sinking test device. The heavy medium recovery device 8 is a recovery pipeline, and a solenoid valve 9 is provided on the recovery pipeline of the heavy medium recovery device 8. The solenoid valve 9 is controlled by the control system 5. The solenoid valve 9 is opened by the control system 5 to collect the heavy medium into a sealed barrel for sealed storage to prevent oxidation.

[0032] The base box 11 is provided with a control system 5 and an emergency battery power supply device 6. The emergency battery power supply device 6 is a large-capacity lithium battery. The design of the emergency battery power supply device 6 can realize the completion of the test in a power-free environment such as a field geological exploration site.

[0033] The control system 5 is electrically connected to the emergency battery power supply device 6, and the control system 5 is electrically connected to the power device 4, and the rotation speed of the power device 4 can be adjusted by the control system 5 to change the stirring intensity of the stirring device 3. The control system 5 integrates motor speed regulation, lithium battery voltage transformation, lithium battery charging and circuit protection functions.

[0034] like Figures 1 to 3As shown, a power device 4 is provided in the base box 11, and the power device 4 is connected to the stirring device 3 through the transmission device 12. The transmission device 12 is sealed and rotatably connected to the outer barrel 7 of the floating and sinking test device, and the stirring device 3 is arranged in the mesh filter 2. The mesh filter 2 is a barrel-shaped structure, and a screen 10 is provided at the lower part of the mesh filter 2. The screen 10 is suspended and has a certain distance from the bottom of the outer barrel 7 of the floating and sinking test device. The screen 10 adopts a 0.5mm standard screen. The design of the screen 10 facilitates the collection of the floating and sinking test sediment. After the stirring is completed, the anti-splash protection device 1 is opened, and the mesh filter 2 is lifted upward so that the stirring device 3 on the screen 10 is removed from the transmission shaft 12-2, and the mesh filter 2 and the stirring device 3 can be taken out from the barrel mouth of the outer barrel 7 of the floating and sinking test device. In the process of taking out, the screen 10 filters the test liquid and realizes the separation of the sediment and the heavy medium.

[0035] like Figure 4 As shown, the power device 4 is a brushless servo motor, and the motor output shaft 4-1 of the power device 4 is connected to the transmission device 12. The transmission device 12 includes a key sleeve 12-1 and a transmission shaft 12-2. The key sleeve 12-1 is a guide sleeve, and the key sleeve 12-1 is arranged on the motor output shaft 4-1. The other end of the key sleeve 12-1 is provided with a transmission shaft 12-2, and the transmission shaft 12-2 is sealed and rotatably connected to the bottom of the outer barrel 7 of the floating and sinking test device, and the upper end of the transmission shaft 12-2 passes through the reserved hole at the bottom of the mesh filter 2 and is then disassembled and connected to the stirring device 3.

[0036] In this embodiment, the outer barrel 7 of the floating and sinking test device is detachably connected to the base box 11. Specifically, a reserved through hole matching the gear key sleeve 12-1 and the transmission shaft 12-2 is provided at the bottom of the outer barrel 7 of the floating and sinking test device. The outer barrel 7 of the floating and sinking test device is sleeved on the gear key sleeve 12-1 and the transmission shaft 12-2 with the help of the reserved through hole. In this way, the outer barrel 7 of the floating and sinking test device is directly buckled on the base box 11. This simple disassembly and connection design facilitates the disassembly, cleaning and transportation of the device.

[0037] like Figures 5 to 8As shown, the stirring device 3 includes a fixed end 3-1 and a rotating end 3-2. The fixed end 3-1 is fixedly connected to the screen 10 at the bottom of the mesh filter 2, and the fixed end 3-1 is rotatably connected to the rotating end 3-2 through a sealed bearing 3-3. The rotating end 3-2 is detachably connected to the butt end 12-3 of the transmission shaft 12-2, and a stirring blade 3-4 is arranged on the rotating end 3-2. The butt end 12-3 is a polygonal cylinder, and a docking port 3-5 with a polygonal inner cavity is arranged in the rotating end 3-2, and the butt end 12-3 is plugged and matched with the docking port 3-5. During installation, align the butt end 12-3 of the transmission shaft 12-2 with the docking port 3-5 and insert and tighten it. When the power device 4 is started, the motor output shaft 4-1 rotates, and the transmission shaft 12-2 is driven to rotate by the key sleeve 12-1, and the transmission shaft 12-2 drives the rotating end 3-2 of the stirring device 3 to rotate to realize the stirring function.

[0038] like Figures 1 to 8 As shown, the use process of the present invention is as follows:

[0039] First, check whether all parts of the equipment are installed accurately, open the splash protection device 1, add the prepared heavy medium into the mesh filter 2, cover the splash protection device 1, start the power device 4, rotate the motor output shaft 4-1, drive the transmission shaft 12-2 to rotate with the help of the key sleeve 12-1, and drive the stirring device 3 to rotate to stir the heavy medium in the mesh filter 2. The stirring intensity of the stirring device 3 can be changed by adjusting the speed of the power device 4 using the control system 5. After the heavy medium is stirred evenly, open the splash protection device 1, slowly add the mineral sample used in the test, cover the splash protection device 1, and wait for 10 minutes. Because some materials in the heavy medium have a large density, once the stirring is stopped, they will settle to the bottom, affecting the use effect of the heavy medium, and will also have an adverse effect on the stirring device 3. Therefore, during this process, the stirring device 3 keeps stirring. When the added minerals are stirred and mixed with the heavy medium, due to the different densities, according to the buoyancy principle, the mineral particles with a density less than the medium density will float, while the mineral particles with a density greater than the medium density will sink. Open the anti-splash protection device 1 and use a colander to pick up the floating objects that float to the surface of the liquid, and observe regularly, and continuously pick up the newly floating floating objects until no new floating objects are generated. After all the floating objects are picked up, turn off the power device 4, lift the mesh filter 2 upward so that the stirring device 3 on the screen 10 is removed from the transmission shaft 12-2, and slowly take out the mesh filter 2 from the outer barrel 7 of the floating and sinking test device. During the removal process, gently shake the mesh filter 2, and the screen 10 will separate the test sink and the heavy medium. The test sink will be filtered out by the screen 10 and collected uniformly. At this time, the remaining liquid in the outer barrel 7 of the floating and sinking test device is the heavy medium liquid. Open the solenoid valve 9 to collect the heavy medium through the heavy medium recovery device 8 into the sealed barrel and seal it for preservation to prevent oxidation.

[0040] After the test, a small amount of heavy medium will remain in the outer barrel 7 of the floating and sinking test device. The outer barrel 7 of the floating and sinking test device can be lifted up and removed from the base box 11 to clean the outer barrel 7 of the floating and sinking test device. When working in a field environment, the emergency battery power supply device 6 can be started to supply power to ensure the normal operation of the equipment.
