Description

Technical Field

[0001] This utility model relates to the technical field of hydrometallurgical testing equipment, specifically to a multifunctional mining rolling bottle testing device. Background Technology

[0002] In hydrometallurgy, to rapidly assess the feasibility of heap leaching for low-grade oxidized gold and copper ores, and the feasibility of bio-oxidative heap leaching for primary gold and copper ores, rolling flask tests are conducted after crushing the ore to a particle size of 3-5 mm. This allows for the acquisition of experimental data in a short time, which can be used to assess whether further column leaching tests are necessary. The results of the rolling flask test can corroborate the results of the column leaching test. The purpose of the rolling flask test is to determine the optimal concentration of the leaching agent, the amount of leaching agent consumed, the leaching rate of useful elements, and the leaching liquid-to-solid ratio. It also aims to study various process parameters during the leaching process and to make a preliminary evaluation of the prospects for mining deposits using heap leaching.

[0003] Depending on the process, leaching systems are typically classified into acidic leaching systems, alkaline leaching systems, and bacterial bioleaching systems. Therefore, the rolling flask needs to be acid and alkali resistant, corrosion resistant, and abrasion resistant. Materials can include plexiglass, stainless steel, and PVC. The rolling flask is a hollow cylinder with a certain wall thickness and tapered ends. Its structure needs to facilitate the addition of minerals and water, and at the end of the test, it should be easy to pour out all solids and liquids from the rolling flask and measure the corresponding elements. During the rolling flask test, the rolling flask is placed on two rollers of the rolling flask machine, generally using an active roller driving a passive roller. Different types of tests have different conditions and operational requirements; for example, bio-oxidation rolling flask tests require temperature control, rotation speed control, and gas filling. However, existing rolling flask testing equipment and corresponding rolling flasks can only adapt to one type of rolling flask test. Therefore, it is necessary to configure corresponding rolling flask testing equipment for each type of rolling flask test to meet the requirements of rolling flask testing. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings. It should be noted that this embodiment is based on the present technical solution and provides detailed implementation methods and specific operation processes, but the protection scope of the present invention is not limited to this embodiment.

[0024] This embodiment provides a multifunctional mining bottle rolling test device, such as... Figure 1-5 As shown, it includes a bottle rolling machine and a bottle rolling mechanism.

[0025] The bottle rolling machine includes an outer casing 1, an upper row of rollers 2, a lower row of rollers 3, an air pump, a cooling and heating temperature control device, and a variable speed motor. The upper row of rollers 2 and the lower row of rollers 3 each include four rollers. Among the four rollers, the two rollers in the middle are active rollers 4, and the two rollers on both sides are passive rollers 5. The active rollers 4 and the adjacent passive rollers 5 are connected by a drive (e.g., through a drive belt). The outer casing 1 has an isolated upper space 6 and a lower space 7. The upper row of rollers 2 and the lower row of rollers 3 are respectively located in the upper space 6 and the lower space 7. The upper space 6 and the lower space 7 are each equipped with an independent air pump, a cooling and heating temperature control device, and a variable speed motor. Each active roller 4 is driven axially by an independent variable speed motor. The air pump is connected to the bottle rolling machine 9 through a detachable air filling accessory 8.

[0026] In the aforementioned bottle rolling machine, the roller speed, ambient temperature, and the start and stop of bottle inflation can be independently controlled for the upper and lower spaces. The roller speed control range is 0-500 r / min, and the ambient temperature control range is 0-100℃.

[0027] In this embodiment, both the upper space 6 and the lower space 7 are equipped with openable doors 21 on their front sides.

[0028] In this embodiment, the air outlet of the air pump is connected to a stop valve, which can be closed when inflation is not required.

[0029] In this embodiment, the diameter of each roller is The distance between the two active rollers is 300-600mm, and the distance between the passive roller and the adjacent active roller is adjustable, with an adjustable range of 80-500mm, to meet the needs of different models of roller bottles.

[0030] In this embodiment, both the upper space 6 and the lower space 7 are equipped with drawer-type shelves 10, and the upper rollers 2 and the lower rollers 3 are respectively mounted on the drawer-type shelves 10 in the upper space 6 and the lower space 7. Specifically, the maximum distance that the drawer-type shelves can be pulled out is 0.5m. The drawer-type shelves facilitate the placement and removal of bottles on the rollers.

[0031] In this embodiment, the rolling bottle 9 is made of plexiglass or PVC and is suitable for rolling bottle tests in acidic leaching systems, alkaline leaching systems, and bacterial bioleaching systems. The rolling bottle 9 includes a hollow cylinder 11, both ends of which are sloping end structures 12. Each end of the sloping end structure 12 away from the hollow cylinder 11 is provided with a detachable rolling bottle cap 13.

[0032] In this embodiment, the roller cap 13 can be an inflatable roller cap 14 (e.g., Figure 5 As shown in (a)), the standard roller cap 15 (as shown in the figure) Figure 5 (as shown in (b)) and the loading and unloading cylinder cap 16 without an opening (as shown in (b)). Figure 5 (as shown in (c)).

[0033] The inflatable roller cap 14 is used in roller test scenarios that require inflation, the conventional roller cap 15 is used in roller test scenarios that require ventilation, and the loading and unloading roller cap 16 is used in the loading and unloading process.

[0034] The inflatable roller cap 14 has an opening 141 for connecting an air pump. The diameter of the opening 141 of the inflatable roller cap 14 matches that of the detachable inflatable accessory, and is [diameter missing].

[0035] The diameter of the opening on the conventional rolling cap is smaller than the diameter of the end of the inclined rim structure furthest from the hollow cylinder. The rolling process is a centrifugal motion; therefore, the sample moves along the bottle wall during rolling. While ventilation is required, the conventional rolling cap with the opening provides some protection to the outer edge of the bottle opening, preventing slurry leakage.

[0036] In this embodiment, the hollow cylinder 11 of the roller bottle 9 is provided with protruding anti-wear rings 17 at both ends of its outer surface, which can prevent the roller bottle from being worn out during use and causing the test liquid to flow out.

[0037] Furthermore, in this embodiment, several pairs of anti-collision baffles 18 are provided between the passive roller 5 and the adjacent active roller 4. Each pair of anti-collision baffles 18 can accommodate a roller 9, and the upper edge of the anti-collision baffle 18 corresponds to the lower edge of the roller cap 13. By providing several pairs of anti-collision baffles 18 between the passive roller 5 and the active roller 4, multiple rollers can be placed between the passive roller 5 and the active roller 4 for simultaneous testing. Placing the rollers between each pair of anti-collision baffles 18 can prevent the rollers from colliding with each other. Aligning the upper edge of the anti-collision baffle with the lower edge of the roller cap avoids obstructing the opening at the center of the roller cap.

[0038] In this embodiment, the surface at the connection between the sloping end cap structure 12 and the hollow cylinder 11 is smooth, preventing ore from getting stuck and facilitating ore unloading.

[0039] In this embodiment, the diameter of the hollow cylinder 11 of the rolling bottle 9 is The length is 100-500mm.

[0040] Furthermore, all types of roller caps 13 are equipped with waterproof sealing rings.

[0041] In this embodiment, the outer peripheral surface of the roller cap 13 is provided with anti-slip protrusions 19, which can increase the friction of the roller cap surface, making it easier to open the roller cap and thus making it easier to replace different types of roller caps for the roller bottle to meet the testing requirements such as loading and unloading ore and gas filling.

[0042] In this embodiment, the outer casing 1 is also provided with a control panel 20, which is communicatively connected to the air pump, motor and refrigeration and heating temperature control device.

[0043] The working principle of the above device is as follows:

[0044] Sampling in a rolling bottle: Place a closed loading / unloading rolling bottle cap on the sloping end of one end of the rolling bottle and tighten it. Then, with the loading / unloading rolling bottle cap facing down, place the rolling bottle vertically. Add ore, water, and reagents into the rolling bottle through the sloping end to form the test system. Next, place an inflatable rolling bottle cap (suitable for biological oxidation rolling bottle tests) or a conventional rolling bottle cap (suitable for non-biological oxidation rolling bottle tests) on the sloping end of the rolling bottle and tighten it. Place the rolling bottle horizontally and replace the loading / unloading rolling bottle cap with an inflatable or conventional rolling bottle cap. Then, transport the rolling bottle to the rolling bottle machine and place it between the active and passive rollers. Turn on the motor; the motor drives the active roller to rotate at the set speed. The active roller drives the passive roller to rotate via a belt. Under the drive of the active and passive rollers, the rolling bottle begins to roll axially. When conducting a biological oxidation rolling flask experiment, the ambient temperature can be controlled by heating / cooling through a refrigeration and heating temperature control device. The opening of the inflatable rolling flask cap can be connected to an air pump using a detachable air filling accessory, and the air pump can be used to fill the inside of the rolling flask with air.

[0045] Roller bottle sampling: After the roller bottle operation is completed, move the roller bottle to the operating table. Replace the inflatable or conventional roller bottle cap at one end with the loading / unloading ore roller bottle cap. Then, place the roller bottle vertically with the loading / unloading ore roller bottle cap facing down at the other end. Unscrew the inflatable or conventional roller bottle cap at the other end facing up, invert the roller bottle, and pour the ore sample into a basin. Next, unscrew the loading / unloading ore roller bottle cap, use a rubber bulb to absorb the leachate, and repeatedly rinse the ore sample from all parts of the roller bottle into the basin until no residue remains, ensuring the concentration of the liquid sample. Finally, wash the entire roller bottle with tap water. Afterward, wash the residue sample thoroughly, dry it, measure it, mix it evenly, and prepare a sample for testing the corresponding elements to assess the leaching rate of the target metal and reagent consumption.

[0046] For those skilled in the art, various corresponding changes and modifications can be made based on the above technical solutions and concepts, and all such changes and modifications should be included within the protection scope of the claims of this utility model.
