[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.

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.

This equipment 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.
