Description

Technical Field

[0001] The invention belongs to the technical field of fire assay, and in particular relates to a fire assay mixing system. Background Art

[0002] Fire assay is the application of geochemical principles to mineral exploration. The purpose is to use chemical methods to help customers locate the geographical location of sedimentary deposits and the extension of discovered deposits. Exploration geochemistry includes the analysis of the following samples: cores, rocks, river sediments, soils, glacial debris or vegetation, etc.

[0003] The main process steps of fire assay include sampling, melting, baking pan assay, weighing, gold and silver separation, weighing, etc. Among them, mixing belongs to the melting stage. The main process is to mix the test sample with other auxiliary solvents, and then put them into the crucible and send them to the furnace for heating and melting. The whole mixing process requires uniform mixing and no sample loss. At present, the industry still uses manual work. Each sample needs to be packed together with the ingredient solvent with a fresh-keeping tape, and the air in the bag is driven out by hand and then tied. Because it is all powder, there is a lot of dust when the air is driven out. The dust contains heavy metals that are harmful to health after inhalation. Although the site is equipped with a vacuum cleaner and a mask, the effect is not ideal; after the fresh-keeping bag is knotted, it is necessary to repeatedly shake the fresh-keeping bag by hand until it is mixed evenly. The amplitude and frequency of manual shaking are poorly consistent, and the mixing effect needs to be confirmed repeatedly; each sample needs to be bagged, knotted and shaken separately, which is extremely inefficient and the workload of the operator is large; some samples need to be filled with silver nitrate solution separately, because the amount is very small, and it is currently titrated manually with a dropper. The titration dosage is unstable and deviated each time, which affects the experimental data.

[0004] The above description of the background technology is only for facilitating an in-depth understanding of the technical solution of the present invention (such as the technical means used, the technical problems solved and the technical effects produced), and should not be regarded as an admission or any form of implication that the information constitutes prior art already known to those skilled in the art.

The lifting module 42 is provided with a limiting mechanism 44 on both sides for limiting the two sides of the tray 8, and the lifting module 42 and the limiting mechanism 44 can move up and down.

[0042] The silver nitrate delivery mechanism 6 is used to inject silver nitrate solution into the crucible 81 of the tray 8 on the second double-forked transplanting mechanism 5. The silver nitrate delivery mechanism 6 includes a liquid adding gun 61 that can move in the XYZ three-axis direction, and the liquid adding gun 61 is connected to the silo 63 through a transfer valve 62.

[0043] A connecting mechanism 7 is provided between the second double-fork transplanting mechanism 5 and the conveying line, and the connecting mechanism 7 includes a plurality of electric rollers 71 .

[0044] The specific working steps and principles of the fire assay mixing system of this embodiment are as follows:

[0045] The pallet 8 is transported by the conveyor line to the lifting and transverse moving machine 21 of the first double-fork transplanting mechanism 2. The initial state of the lifting and transverse moving machine 21 is the lifting state, which is at the same height as the conveyor line. The pallet 8 continues to be transported on the lifting and transverse moving machine 21 until it is blocked by the buffer blocking cylinder 31 on the pallet blocking mechanism 3. The first in-position sensor 25 and the second in-position sensor 32 are triggered at the same time to determine that the pallet 8 has been transported to the position; the RFID reader 24 on the lifting and transverse moving machine 21 begins to read the RFID chip 83 at the bottom of the pallet 8 and upload the information. After the reading is completed, the lifting and transverse moving machine 21 begins to descend, and the pallet 8 falls on the upper fork plate 22 of the first double-fork transplanting mechanism 2. When descending, the pin hole 82 on the pallet 8 just falls on the positioning pin 23 of the first double-fork transplanting mechanism 2 to complete the positioning. The distance detection sensor 26 detects that the pallet 8 has descended to the position, and the first double-fork transplanting mechanism 2 extends the upper fork plate 22 to the right, driving the pallet 8 on the upper fork plate 22 to move toward the mixing mechanism 4.

[0046] The tray 8 begins to enter the mixing mechanism 4. There are first height sensors 45 at both ends of the mixing mechanism 4. The first height sensor 45 is used to detect whether the tray 8 is too high because it is not placed flat. After the tray 8 is moved into place, the distance sensor 46 detects whether the tray is placed flat. After detecting that it is placed flat, the side sensor 47 detects whether the two sides of the tray 8 are in place. After detecting that it is in place, the lifting module 42 lifts the entire tray 8 upward until the tray 8 is supported by the limit column 49. At this time, the upper end opening of the crucible 81 is just pressed on the silicone plate 43. The material of the silicone plate 43 is relatively soft. The upper end opening of the crucible 81 is sunk into the silicone plate 43 to seal the crucible mouth. The second height sensor 48 is triggered to confirm that the tray 8 is in place. After being lifted into place, the cylinders of the limiting mechanisms 44 on both sides extend and retract upward at the same time, pressing the upper inclined surfaces on the limiting plates of the limiting mechanisms 44 against the two sides of the tray 8, so as to ensure that the crucible 81 will not shift left and right during the rotation process. Subsequently, the rotating motor 40 is started, and the rotating frame 41 starts to rotate 360° to mix the materials. The rotating frame 41 is reset after repeatedly rotating for several circles; the second double-fork transplanting mechanism 5 extends the upper fork plate into the mixing mechanism 4, and the lifting module 42 on the mixing mechanism 4 retracts downward to drive the tray 8 to fall on the upper fork plate of the second double-fork transplanting mechanism 5, and the pin hole 82 on the tray 8 falls on the positioning pin of the second double-fork transplanting mechanism 5 to complete the positioning, and the second double-fork transplanting mechanism 5 retracts backward, and the tray 8 completes the mixing.

[0047] After the tray 8 is in place, the RFID reader on the lifting and traversing machine of the second double-forked transplanting mechanism 5 reads the RFID chip 83 at the bottom of the tray 8 again and uploads the information. After reading, the silver nitrate delivery mechanism 6 starts to move, and according to the information read by the system, the Z axis moves to the top of the crucible in need, and the Z axis moves downward to make the liquid adding gun 61 go deep below the crucible cup mouth. The liquid in the silo 63 containing the silver nitrate solution is transported to the liquid adding gun 61 through the system-controlled liquid transfer valve 62, and a certain dose of silver nitrate solution is injected according to demand. After the filling is completed, the Z axis retracts, and the silver nitrate delivery mechanism 6 moves to the initial position. The lifting and traversing machine of the second double-forked transplanting mechanism 5 lifts the tray 8 upward and transports it to the docking mechanism 7. The docking mechanism 7 relies on the electric roller 71 to transport the tray 8 to the conveyor line connected behind.

[0048] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present invention fall within the protection scope of the present invention.
