[0016] Please see Figure 1 An adjustable programmable flow sampler according to a preferred embodiment of this application includes a housing 1, a sliding device 2, and a ore-collecting device 3. The upper part of the housing 1 is provided with the sliding device 2, the left side of the sliding device 2 is connected to the upper part of the ore-collecting device 3, and the lower part of the ore-collecting device 3 is embedded in the housing 1. The box 1 includes a flow box 10, a sampling and receiving box 11, and a slurry box 12. The upper left part of the box 1 is the flow box 10. The lower right part of the flow box 10 is provided with a slurry transfer port 13. The slurry transfer port 13 is embedded inside the slurry box 12. The sampling and receiving box 11 is provided below the slurry transfer port 13. The sliding device 2 includes a slide support 20, a slide 21, and a PLC control box 22. The upper part of the slurry tank 12 is provided with a slide support 20, and the upper part of the slide support 20 is slidably connected to the slide 21. The slide 21 is electrically connected to the PLC control box 22. The ore extraction device 3 includes a sampling tube seat 30, a support roller 31, a roller track 32, and a sampling tube 33. The sampling tube seat 30 is connected to the left side of the slide table 21. The support roller 31 is connected to the lower left part of the sampling tube seat 30. The roller track 32 is slidably connected to the lower part of the support roller 31. The sampling tube 33 is fixed between the sampling tube seat 30 and the support roller 31. The lower part of the sampling tube 33 passes through the slurry tank 12 and then enters the sampling receiving box 11. The left side wall of the part of the sampling tube 33 that passes through the slurry tank 12 has an opening, which corresponds to the opening of the slurry transfer port 13 in the slurry tank 12.

[0019] During use, the PLC control box 22 controls whether sampling is performed, the sampling location, and the sampling quantity to meet the sampling requirements in daily production activities.
[0020] This sampler can only be used on gravity-flow pipelines. The sampler is a section of the entire slurry pipeline; the entire slurry flow must enter the flow box to ensure sampling accuracy. After sampling, the slurry must be able to smoothly flow into the next section of the pipeline to the required process location.
[0021] The size of the sampler is determined by the diameter and flow rate of the pipe to be sampled. The size of the flow box and the width of the waterfall must meet the requirements of a flow velocity of <0.6m / s and the available space. The design of the sampling collection box must ensure the complete collection of samples for each sampling, while preventing the mixing of other slurries to ensure sample accuracy. The selection of the slide table must also meet the relevant technical parameters such as length and rigidity. The speed ratio of the reducer and the power of the servo motor must also meet the requirements. The slurry tank must meet the available space dimensions for easy installation, while ensuring sufficient space to prevent non-sample slurries from mixing into the sampling collection box and to ensure that the slurry flows smoothly into the main pipe.
[0022] In summary, this invention provides an adjustable programmable flow-through sampler. This device has a simple and reliable structure, and can be manufactured to meet the GB / T44034-2024 standard by utilizing existing technology combinations. PLC programming allows for sampling at various required sampling locations, greatly facilitating automated management for enterprises. Furthermore, the PLC slide table allows for easy adjustment of the sampling tube's movement speed to accommodate sampling at different slurry flow rates. In other words, after programming, the sampling time and number of sampling attempts can be precisely controlled, meeting sampling accuracy requirements.
[0023] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
