Description

Technical Field

[0001] This utility model relates to the field of mineral air separation device technology, and in particular to an air separation device for mineral samples containing particulate gold. Background Technology

[0002] During the grinding and preparation of samples containing particulate gold, due to the good ductility of gold, it is difficult to grind it into powder with smaller particle size along with other mineral components. After the grinding process, gold still exists in the sample in the form of larger particle size, resulting in poor sample representativeness and large differences in results.

[0003] The fire assay method is an important testing method for gold and silver analysis and trade arbitration both domestically and internationally, with a standard sample size of approximately 10-20g. However, in determining the gold content of samples containing particulate gold using the fire assay method, the number of particulate gold particles in the sample taken by the testing personnel is highly random, leading to significant variations in the gold content test results for each sample and making it difficult to accurately determine the true grade of the sample.

[0004] To improve the accuracy of gold content determination in samples containing particulate gold, most laboratories currently use the method of averaging multiple measurements to make the test data close to the gold content of the sample (even measuring 10-20 times), which wastes testing costs, has low testing efficiency, and the test data is also subject to randomness. A few laboratories use the sieving and fire assay method, but the sieving process is time-consuming and it is difficult to control losses. Utility Model Content

[0005] To address the shortcomings of existing methods for measuring the gold content of gold-containing samples, which suffer from low detection efficiency and unpredictable data, this embodiment provides an air-separation device for mineral samples containing gold particles. Utilizing air as the separation medium, the device separates light and heavy substances in the material based on the difference in suspension velocity between the material and impurities. Under the action of airflow, the substances are further separated according to density and particle size, thereby allowing for the measurement of the gold content of the gold-containing sample.

[0006] To solve the above-mentioned technical problems, the following technical solution is proposed:

[0007] This application provides an air separation device for mineral samples containing particulate gold, comprising:

[0008] frame;

[0009] A blower device, which is installed within the frame, is used for air separation of mineral samples;

[0010] The frame is provided with multiple sets of the collecting device, and the multiple sets of the collecting device are arranged sequentially along the blowing direction of the blower. The collecting device is used to collect mineral samples after air separation.

[0011] An adjusting baffle is movably disposed within the frame and can move along the blowing direction of the blower. The adjusting baffle is disposed between two adjacent receiving devices and extends into the receiving device on the side away from the blower. It is used to receive mineral samples after air separation and to collect the received mineral samples in the receiving device on the side away from the blower.

[0012] Furthermore, in this embodiment, the adjusting baffle is provided with a sliding rod, the side wall of the frame is provided with a sliding groove, the adjusting baffle is movably disposed in the sliding groove via the sliding rod, and the sliding rod extends out of the frame through the sliding groove.

[0013] Furthermore, in this embodiment, the adjusting baffle is provided with an inclined surface on the side away from the blower, and the inclined surface is inclined towards the receiving device.

[0014] Furthermore, in this embodiment, a pre-filter is also included, which is disposed at the air outlet of the blower.

[0015] Furthermore, in this embodiment, the air outlet of the blower is horn-shaped.

[0016] Furthermore, in this embodiment, the receiving device has a funnel-shaped structure.

[0017] Furthermore, in this embodiment, the blower is disposed on one side of the frame, and the frame has an exhaust port opposite to the side where the blower is disposed, for discharging the airflow blown out by the blower.

[0018] Furthermore, in this embodiment, an air guide plate is also provided inside the frame, and the air outlet is located at the top of the frame. The air guide plate is used to guide the airflow blown out by the blower to the exhaust port.

[0019] Furthermore, in this embodiment, a filter screen is also provided at the exhaust vent.

[0020] Furthermore, in this embodiment, a self-cleaning device is also included. The self-cleaning device is disposed inside the receiving device and is used to automatically remove mineral samples adhering to the surface of the receiving device.

[0021] Beneficial Effects: This application provides an air-separation device for mineral samples containing particulate gold, including a frame, a blower, a collecting device, and an adjusting baffle. The blower is located within the frame and is used for air-separating the mineral samples. Multiple collecting devices are arranged sequentially along the blowing direction of the blower, and are used to collect the air-separated mineral samples. The strong airflow generated by the blower within the frame passes through the mineral samples. Impurities with lower density are blown up by the airflow and move along the direction of the airflow, falling into the collecting devices farther from the blower. Meanwhile, the denser and heavier gold particles in the mineral samples sink due to gravity or move a short distance horizontally due to inertia, falling into the collecting devices closer to the blower. In this embodiment, the air-separation device filters out particulate gold from the mineral samples, allowing for the measurement of the gold content in the sample. This method not only has high detection efficiency but also provides accurate detection data. Secondly, in this embodiment, an adjusting baffle is also provided within the frame. The adjusting baffle is movably disposed within the frame and can move along the blowing direction of the blower. The adjusting baffle is disposed between two adjacent receiving devices and extends into the receiving device on the side away from the blower. The position of the adjusting baffle movably disposed within the frame is adjusted according to the requirements of the field test and the actual working conditions, thereby adjusting the size of the receiving interface of the two adjacent receiving devices, thereby reducing the amount of heavier impurities falling into the receiving device closer to the blower.

[0039] During the grinding preparation of samples containing particulate gold, due to the good ductility of gold, it is difficult to grind it into powder with a particle size of less than 0.074 mm along with other mineral components. After the grinding process, gold still exists in the sample in the form of larger particles, resulting in poor sample representativeness and large differences in the results.

[0040] The fire assay method is an important testing method for gold and silver analysis and trade arbitration both domestically and internationally, with a standard sample size of approximately 10-20g. However, in determining the gold content of samples containing particulate gold using the fire assay method, the number of particulate gold particles in the sample taken by the testing personnel is highly random, leading to significant variations in the gold content test results for each sample and making it difficult to accurately determine the true grade of the sample.

[0041] To improve the accuracy of gold content determination in samples containing particulate gold, most laboratories currently use the method of averaging multiple measurements to make the test data close to the gold content of the sample (even measuring 10-20 times), which wastes testing costs, has low testing efficiency, and the test data is also subject to randomness. A few laboratories use the sieving and fire assay method, but the sieving process is time-consuming and it is difficult to control losses.

[0042] To address the shortcomings of existing methods for measuring the gold content of gold-containing samples, which suffer from low detection efficiency and unpredictable data, this embodiment provides an air-separation device for mineral samples containing gold particles. Utilizing air as the separation medium, the device separates light and heavy substances in the material based on the difference in suspension velocity between the material and impurities. Under the action of airflow, the substances are further separated according to density and particle size, thereby allowing for the measurement of the gold content of the gold-containing sample.

[0043] like Figure 1 As shown, Figure 1 This application provides a schematic diagram of the structure of an air separation device for a mineral sample containing particulate gold, including a frame 1, a blower 2, and a collecting device 3. The blower 2 is set inside the frame 1 and is used to perform air separation on the mineral sample. Multiple sets of collecting devices 3 are provided inside the frame 1, and the multiple sets of collecting devices 3 are arranged sequentially along the blowing direction of the blower 2. The collecting devices 3 are used to collect the mineral sample after air separation.

[0044] It is understandable that, such as Figure 2 As shown, in this embodiment, the blower 2 is activated, and the mineral sample containing gold particles is transported into the frame 1. The powerful airflow generated by the blower 2 within the frame 1 passes through the mineral sample. Impurities with lower density within the mineral sample are blown up by the airflow and move along the direction of the airflow, falling into the receiving device 3, which is farther away from the blower 2. Meanwhile, the gold particles with higher density and heavier weight within the mineral sample sink under the influence of gravity or move a short distance horizontally due to inertia, falling into the receiving device 3, which is closer to the blower 2. In this embodiment, the gold particles are screened from the mineral sample by the air separation device, and then the gold content of the sample containing gold particles is measured. This not only has high detection efficiency but also provides accurate detection data.

[0045] Secondly, in this embodiment, an adjusting baffle 4 is also provided within the frame 1. The adjusting baffle 4 is movably disposed within the frame 1 and can move along the blowing direction of the blower 2. The adjusting baffle 4 is disposed between two adjacent receiving devices 3, extending into the receiving device 3 on the side away from the blower 2. It is used to receive the mineral samples after air separation and to collect the received mineral samples in the receiving device 3 on the side away from the blower 2. It is understood that since there may still be heavy impurities in the mineral samples, when the blower 2 performs air separation on the mineral samples, the heavier impurities may fall into the receiving device 3 closer to the blower 2, affecting the accuracy of the test results. Therefore, in order to improve the accuracy of the test results, in this embodiment, the position of the adjusting baffle 4 movably disposed within the frame 1 can be adjusted according to the requirements of the on-site test and the actual working conditions, thereby adjusting the size of the receiving interface of the two adjacent receiving devices 3, thereby reducing the amount of heavier impurities falling into the receiving device 3 closer to the blower 2.

[0046] For example, in this embodiment, the adjusting baffle 4 is provided with a sliding rod 5, and the side wall of the frame 1 is provided with a sliding groove. The adjusting baffle 4 is movably disposed in the sliding groove via the sliding rod 5, and the sliding rod 5 extends out of the frame 1 through the sliding groove. It can be understood that in this embodiment, the end of the sliding rod 5 extends out of the frame 1, and the user can adjust the position of the adjusting baffle 4 by moving the sliding rod 5 that extends out of the frame 1, making it easier for the user to operate the air separation equipment.

[0047] For example, in this embodiment, the adjusting baffle 4 is provided with an inclined surface 6 on the side away from the blower 2, and the inclined surface 6 is inclined towards the receiving device 3. During use, when impurities separated from the mineral sample fall onto the adjusting baffle 4, the inclined surface 6 on the adjusting baffle 4 allows the impurities to automatically slide into the receiving device 3 on the side away from the blower 2, further reducing the operation difficulty of the air separation equipment.

[0048] Furthermore, such as Figure 3 As shown, in this embodiment, a pre-filter 7 is also included. The pre-filter 7 is set at the exhaust port 8 of the blower device 2. By setting the pre-filter 7 at the exhaust port 8 of the blower device 2, the airflow blown out by the blower device 2 is more uniform.

[0049] For example, in this embodiment, the air outlet of the blower 2 has a trumpet-shaped structure. The trumpet-shaped air outlet can not only increase the air outlet area and accelerate the gas flow rate, thereby increasing the air speed and air volume at the air outlet, but also make the airflow more evenly distributed at the outlet, avoiding the concentration and unevenness of the airflow.

[0050] For example, such as Figure 4 As shown, in this embodiment, the material collection device 3 has a funnel-shaped structure. The funnel-shaped material collection device 3 can effectively collect materials, allowing the materials to flow naturally to the discharge port under the action of gravity, thereby improving the collection efficiency.

[0051] Furthermore, in this embodiment, the blower device 2 is disposed on one side of the frame 1, and the frame 1 is provided with an exhaust port 8 on the side where the blower device 2 is disposed. After the airflow blown out by the blower device 2 passes through the frame 1, it is discharged from the exhaust port 8 on the other side of the frame 1, which can effectively prevent the airflow blown out by the blower device 2 from forming backflow turbulence in the frame 1, so as to affect the sorting of mineral samples.

[0052] For example, in this embodiment, a guide plate 9 is also provided inside the frame 1, and an exhaust port 8 is located at the top of the frame 1. The guide plate 9 is used to guide the airflow blown out by the blower 2 to the exhaust port 8. It can be understood that during air separation, the airflow can be guided out according to the guide plate 9, further avoiding the formation of backflow turbulence within the frame 1. For example, in this embodiment, the guide plate has an arc-shaped structure or has two different slope angles, that is, the slope of the guide plate increases towards the exhaust port.

[0053] For example, in this embodiment, a filter screen 10 is also provided at the exhaust port 8. It is understood that there are some fine substances in the mineral sample, which can move with the airflow blown out by the blower 2. Therefore, setting a filter screen 10 at the exhaust port 8 can prevent sample loss.

[0054] For example, such as Figure 5 As shown, in this embodiment, a self-cleaning device is also included. The self-cleaning device is set inside the frame 1 and is used to remove the mineral samples inside the frame 1. It can be understood that during the air separation process of the mineral samples, some mineral samples will be scattered inside the frame 1. Therefore, the self-cleaning device removes the mineral samples scattered inside the frame 1, thereby ensuring the cleanliness of the air separation equipment.

[0055] For example, the self-cleaning device includes a high-pressure gas input device 11, an air extraction device 12, and a filter device 13. The high-pressure gas input device 11, the air extraction device 12, and the filter device 13 are all connected to the frame 1. The high-pressure gas input device 11 delivers high-pressure gas into the frame 1 to perform air blowing cleaning of the inside of the equipment. At the same time, the air extraction device 12 is turned on to perform negative pressure adsorption, adsorbing excess samples in the equipment into the filter device 13, thereby achieving the purpose of cleaning the equipment.

[0056] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
