Description

Technical fields:

[0001] This invention belongs to the field of mineral processing equipment technology, and mainly relates to an online slurry sampler and sampling method. Background technology:

[0002] Currently, when performing wet mineral processing, concentrators generally need to take samples at different locations at the discharge port of the shaking table to obtain the grade values ​​of the samples in order to control the quality of the slurry to meet the needs of the next process.

[0003] Due to the lack of dedicated sampling equipment, most mineral processing plants rely on manual sampling, using a sampler to take samples sequentially from different locations at the discharge port of the shaking table. Since the mineral content on the shaking table is constantly changing due to various factors, the aforementioned sampling devices are rudimentary, lacking standardized sampling container volume and location. This results in significant human error affecting both time and sample volume, often introducing substantial sampling errors. Consequently, the analyzed samples fail to reflect the actual production situation, causing considerable inconvenience to mineral processing production management. Summary of the Invention:

[0004] To overcome the shortcomings of the prior art, this invention discloses an online slurry sampler and sampling method that is simple in structure and easy to use, which can ensure that sampling is performed simultaneously at the discharge port of the shaking table within a unit of time, thus guaranteeing the accuracy of the sampling.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows:

[0006] An online slurry sampler, comprising

[0007] A support frame is installed on the cofferdam of the mineral processing shaking table, and the lower part of the support frame has multiple layers of wear-resistant pads.

[0008] Multiple receiving boxes of different widths are assembled into the required width and then suspended on the support frame. The receiving boxes are located between the side wall of the shaking table's embankment and the discharge rubber sheet of the shaking table.

[0009] A positioning pointer is fixed on the support frame, and the upper surface of the positioning pointer has a calibration plate;

[0010] A camera is used to acquire images of the mineral distribution on the plane of the shaking table during sampling.

[0011] The upper plane of the positioning pointer is on the same plane as the rocking table.

[0012] The receiving box includes a first receiving box, a second receiving box, a third receiving box, and a fourth receiving box.

[0013] The width of the first receiving box is 20mm, the width of the second receiving box is 50mm, the width of the third receiving box is 100mm, and the width of the fourth receiving box is 300mm.

[0014] A sampling method for an online slurry sampler includes the following steps:

[0015] 1) Measure the distance between the support frame and the lower edge of the discharge rubber sheet. To meet the dimensional requirements, select several layers of wear-resistant pads and stack them, and fix them to the support frame made of five aluminum materials with countersunk bolts and aluminum profile connectors.

[0016] 2) Take multiple 20mm wide first receiving boxes, 50mm wide second receiving boxes, 100mm wide third receiving boxes and 300mm wide fourth receiving boxes and combine them to form the required sampling width, and hang them on a support frame parallel to the discharge rubber sheet.

[0017] 3) In the non-sampling state, the receiving box is close to the side wall of the shaking table embankment;

[0018] 4) Sampling state: At this time, push the support frame with the receiving box into one side of the shaker so that the receiving box is directly below the discharge rubber and take a sample. At the same time, use the camera to take a picture of the distribution of the wide bandwidth on the shaker. After sampling, pull out the support frame so that the receiving box is close to the side wall of the shaker embankment. Pour the sample from the receiving box into the sample box to complete one sampling.

[0019] 5) If multiple samples are required, repeat the above steps.

[0020] Due to the adoption of the technical solution described above, the present invention has the following advantages:

[0021] This invention provides an online slurry sampler and sampling method, which can perform sampling operations while the mineral processing equipment is running. The sampler's receiving box can cover the entire discharge port of the mineral processing equipment. Different widths can be combined to collect materials according to the different width receiving boxes. Receiving boxes of the same width have the same volume. The camera maps the distribution of mineral bands formed by minerals of different colors and widths on the bed surface with the position of the receiving box below, and the test data of the minerals in the receiving box are matched one-to-one with the actual distribution of mineral bands. The sampling quality and location are more accurate, and this design is simple in structure, easy to operate, and highly efficient. Attached image description:

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0028] An online slurry sampler, as shown in the accompanying drawings, includes a support frame 1, multiple receiving boxes of different widths, a positioning pointer 7, and a camera 12.

[0029] like Figure 1 As shown in Figures 2 or 3, the support frame 1 is mounted on the cofferdam 9 of the mineral processing shaking table. The support frame 1 has multiple layers of wear-resistant pads 2 underneath. To make the sampler lightweight, the support frame 1 is assembled from standard aluminum profiles and connectors. The lengths of the five aluminum profiles of the support frame 1 can be determined according to the actual conditions of different models of shaking tables and other mineral processing equipment. To meet dimensional requirements, several layers of wear-resistant pads 2 are stacked and fixed to the support frame 1 made of five aluminum profiles using countersunk bolts and aluminum profile connectors.

[0030] like Figure 1 As shown, the multiple receiving boxes of different widths are combined to form the required width and then suspended on the support frame 1. The receiving boxes are located between the side wall of the shaking table weir 9 and the discharge rubber sheet 10 of the shaking table.

[0031] Specifically, the receiving box includes a first receiving box 3, a second receiving box 4, a third receiving box 5, and a fourth receiving box 6. The width of the first receiving box 3 is 20mm, the width of the second receiving box 4 is 50mm, the width of the third receiving box 5 is 100mm, and the width of the fourth receiving box 6 is 300mm. The receiving boxes of different widths can be spliced ​​together to form the required width size, which can be adapted to various models of shaking tables.

[0032] like Figure 1As shown, the receiving box consists of five first receiving boxes 3, two second receiving boxes 4, four third receiving boxes 5, and two fourth receiving boxes 6.

[0033] like Figure 1 and 2 As shown, the positioning pointer 7 is fixed on the support frame 1, and the upper surface of the positioning pointer 7 has a calibration plate 8; the upper surface of the positioning pointer 7 is located on the same plane as the shaking table plane 11. The positioning pointer 7 is used to define the edge of the shaking table and mark some representative positions on the shaking table. The camera 12 is used to acquire images of the mineral distribution on the shaking table plane 11 during sampling.

[0034] The calibration plate 8 uses self-designed colors and self-designed marker positions to accurately identify the position and pointing direction of the positioning pointer 7 in the camera 12.

[0035] Camera 12 maps the distribution of mineral bands of different colors and widths on the bed surface to the position of the receiving box below, and maps the test data of the minerals in the receiving box to the actual distribution of the mineral bands.

[0036] A sampling method for an online slurry sampler includes the following steps:

[0037] 1) Measure the distance between the support frame and the lower edge of the discharge rubber sheet. To meet the dimensional requirements, select several layers of wear-resistant pads and stack them, and fix them to the support frame made of four aluminum materials with countersunk bolts and aluminum profile connectors.

[0038] 2) Take multiple 20mm wide first receiving boxes, 50mm wide second receiving boxes, 100mm wide third receiving boxes and 300mm wide fourth receiving boxes and combine them to form the required sampling width, and hang them on a support frame parallel to the discharge rubber sheet.

[0039] 3) In the non-sampling state, the receiving box is close to the side wall of the shaking table embankment;

[0040] 4) Sampling state: At this time, push the support frame with the receiving box into one side of the shaker so that the receiving box is directly below the discharge rubber and take a sample. At the same time, use the camera to take a picture of the distribution of the wide bandwidth on the shaker. After sampling, pull out the support frame so that the receiving box is close to the side wall of the shaker embankment. Pour the sample from the receiving box into the sample box to complete one sampling.

[0041] 5) If multiple samples are required, repeat the above steps.

[0042] This design allows for sampling during the operation of mineral processing equipment. The sampler receiving box can cover the entire discharge port of the mineral processing equipment. Different widths can be combined to collect materials according to the different width receiving boxes. Receiving boxes of the same width have the same volume. Camera 12 maps the distribution of mineral belts formed by minerals of different colors and widths on the bed surface to the position of the receiving box below. The test data of the minerals in the receiving box are matched one-to-one with the actual distribution of mineral belts, resulting in more accurate material collection quality and location. Moreover, this design has a simple structure, is easy to operate, and is highly efficient.

[0043] The parts not detailed above are existing technologies and therefore have not been described in detail.
