Problems solved by technology
The traditional sampling spoon is designed with a flat, small mouth and flat ground, and the sampling volume is small. When the slurry flow rate is high, the sample with a small particle size in the spoon is easily washed out by the slurry, and it is not suitable for sampling the slurry in the pipeline. When the concentration of the slurry is high and the mineral When the particle density is high, the sample tends to settle at the bottom, which makes it difficult to discharge ore and seriously affects the accuracy of sampling.
Common pipeline slurry sampling devices are mostly fixed cutter samplers. This fixed sampler needs to be installed on the pipeline that is often sampled. Since the composition of each part is uneven when the slurry flows in the pipeline, the sampling The representativeness of this kind of sampler is poor. At the same time, this kind of sampler has high cost and poor flexibility. Once the ore is blocked, the sampling function will be lost directly. It is not suitable for temporary pipeline sampling in mineral processing plants.
At present, neither of these two sampling methods for pipeline slurry is suitable for accurate and efficient sampling of open pipeline slurry

Embodiment
[0060] like Figure 1a , 1b , 1c, the open-pipeline slurry sampling device of this embodiment consists of a slurry sampler 33 and a slurry sampling pot 32.
[0061] The pulp sampler 33 includes a sampler body, and the sampler body is in the shape of a variable-diameter pipe with a large upper and a lower small (eg. figure 2 shown). like Figure 3a , 3b , 3c, 3d, the upper end of the sampler is the pulp inlet 1, the lower end of the pulp inlet 1 is the pulp buffer I 2 and the pulp buffer II 4, the pulp buffer I 2 and the pulp buffer II 4 are separated by the pulp baffle I 3 Separated, the lower end of the pulp buffer zone II4 is a cylindrical pulp separation zone Ia, which is divided into a plurality of fan-shaped and same area discharge gaps I9 and a plurality of fan-shaped and same area discharge ore in the circumferential direction. Slot I 23, as shown in the figure, the area of the sample discharge gap I 9 and the ore discharge groove I 23 are the same; in other pref...

The invention discloses an open-pipe ore pulp sampling device, comprising a sampler, wherein the sampler comprises a plurality of sampling and separation zones connected in sequence, and the pulp flows through each sampling and separation zone in sequence; The pulp baffle and the pulp separation zone arranged at the lower part; the pulp baffle is a downward inclined annular baffle; the pulp separation zone includes the ore discharge part and the ore discharge buffer zone, and the ore discharge part makes the ore pulp flowing into the pulp separation zone partially introduced to the discharge buffer zone, and the pulp that flows into the pulp separation zone partially flows out of the pulp separation zone. The ore pulp sampling device of the invention can be used for a small amount of analysis and laboratory test sampling of the ore pulp in multiple open pipelines, so that the pipeline ore pulp sampling is more convenient and fast.
Description
technical field [0001] The invention mainly relates to the field of beneficiation, in particular to an open pipeline ore pulp sampling device. Background technique [0002] In the industrial production of beneficiation, it is often necessary to sample and analyze the products at each stage of beneficiation to monitor the beneficiation production process and provide guidance for the improvement of the beneficiation process. The traditional sampling scoop is designed with a flat, small mouth and flat ground, and the sampling amount is small. When the slurry flow rate is large, the samples with small particle size in the scoop are easily washed out by the slurry, and it is not suitable for the sampling of pipeline slurry. When the particle density is high, the sample is easy to settle at the bottom, which makes it difficult to discharge ore and seriously affects the accuracy of sampling. The common pipeline slurry sampling devices are mostly fixed cutter samplers. This fixed s...
