[0002] With the continuous improvement of mechanization in my country's coal mining, the proportion of fully mechanized underground mining is increasing, leading to a higher proportion of fine coal in the raw coal output. In some mines, the proportion of products with particles smaller than 0.5mm even reaches 40% to 55%. Traditionally, raw coal products are tested using flotation ash content detection methods. These methods typically involve manual sampling, taking a certain amount of sample from each flotation cell for analysis. Flotation is the most widely used and effective method for separating fine and very fine particles, and flotation ash content is a key indicator of flotation products.

[0003] Existing online monitoring technology for flotation ash content involves drawing slurry from the flotation concentrate pipeline and then monitoring it online. This method, like traditional sampling methods, only considers sampling and cannot achieve sampling from multiple flotation systems, and its sampling accuracy is low. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present 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 present invention without inventive effort are within the scope of protection of the present invention.

[0026] Existing methods, such as sampling manually or online, and testing the slurry using flotation ash content analysis, all consider the representativeness of the flotation sample. This representativeness is related to the actual throughput ratio of each system and the sampling ratio used. For example, if the throughput of flotation machine A is 1:1 with that of flotation machine B, then under the same operating conditions, the concentrate yield should also be 1:1. Therefore, the slurry ratio should also be taken at a 1:1 ratio during sampling and testing. If the sample volume is different, the ash content of each flotation system will be inconsistent, thus affecting the final monitoring results.

[0027] Wherein, total ash content = system ash content A * percentage + system ash content B * percentage.

[0028] Based on this, the present invention provides a slurry sampling device and system. It comprises a mixing mechanism and at least one sampling mechanism. The inlet of the sampling mechanism is fixedly connected to the main slurry pipeline, and the outlet of the sampling mechanism is connected to the inlet of the mixing mechanism. Multiple discharge ports are located below the mixing mechanism, each equipped with a discharge valve. The sampling mechanism includes a sampler, a flow meter, and a switching valve. One end of the sampler is fixedly connected to the main slurry pipeline, and the other end is connected to the switching valve, which is connected to the flow meter. The sampler is located below the main slurry pipeline, and the slurry flow direction within the sampler is perpendicular to the slurry flow direction within the main slurry pipeline. This allows for precise control of the sampling volume, ensuring the comprehensiveness and representativeness of the slurry sampling, reducing sampling deviation, minimizing manual intervention, and improving work efficiency and safety.

[0029] Figure 1 This is a schematic diagram of a slurry sampling device provided by this utility model. Figure 1 As shown, the device includes a mixing mechanism and at least one sampling mechanism 200.

[0030] This invention provides a sampling mechanism on the main slurry pipeline 100 of each flotation system and connects multiple sampling mechanisms 200 to a mixing mechanism. The sampling mechanism 200 obtains the amount of slurry in each main slurry pipeline according to the required proportion of each slurry, and the mixing mechanism mixes the various slurries to obtain a precise sampled slurry. This ensures the comprehensiveness and representativeness of the slurry sampling, reduces sampling deviation, reduces manual intervention, and improves work efficiency and safety.

[0031] In one optional embodiment, the sampling mechanism 200 includes a sampler 210, a flow meter 220, and a switching valve 230. One end of the sampler 210 is fixedly connected to the main slurry pipeline, and the other end is connected to the switching valve 230. The flow meter 220 is located at the outlet of the sampler 210 and above the switching valve 230. The sampler 210 is located below the main slurry pipeline, and the slurry flow direction in the sampler 210 is perpendicular to the slurry flow direction in the main slurry pipeline.

[0032] like Figure 2 and Figure 3As shown, specifically, the sampler 210 is installed on the main fluid pipeline of the slurry to be sampled. The inlet of the sampler 210 is located inside the main fluid pipeline of the slurry, and the inlet of the sampler 210 extends to the top of the inner wall of the main fluid pipeline of the slurry. The flow direction of the slurry in the sampler 210 is perpendicular to the flow direction of the slurry in the main fluid pipeline of the slurry, so that the slurry can be completely intercepted and the representativeness of the sample can be improved.

[0033] Furthermore, the sampler 210 is fixedly connected to the main slurry pipeline via a fastener, which includes a first flange and a second flange. The first flange is located at the sampling port of the main slurry pipeline and is fixedly connected to the main slurry pipeline.

When it is necessary to obtain slurry from the main slurry pipeline, the switch valve 230 is opened, and the slurry flows out from the sampler 210.

[0035] In an optional embodiment, the sampling mechanism is connected to the mixing mechanism via a sampling trough, which is located below the discharge port of the sampler 210.

[0036] In an optional embodiment, the sampler 210 further includes a first filter plate, which is disposed at the bottom of the sampling tank. The first filter plate is used to pre-filter the coarse slurry to avoid clogging the mixing mechanism. At the same time, it can be used in conjunction with a coarse slurry camera to realize early warning of coarse slurry.

[0037] In an optional embodiment, the sampler 210 further includes a level gauge installed inside the sampling tank to monitor the liquid level and prevent excessive slurry flow from overflowing the tank. The level gauge is also connected to a switch valve 230, which can be shut off at any time when the slurry volume in the sampling tank becomes too high, preventing overflow.

[0038] In an optional embodiment, it further includes:

[0039] The monitoring mechanism includes a second filter plate 420 and a detection camera 410.

The monitoring mechanism is used to monitor coarsening of the slurry particle size, providing alarms for upstream equipment conditions to prevent coarsening.

[0040] In an optional embodiment, the mixing mechanism includes a drive motor and a stirring assembly 300. The drive motor is connected to the stirring assembly 300, the inlet of the stirring assembly 300 is connected to the outlet of the sampler, and the drive motor drives the stirring assembly 300 to rotate.

[0041] Specifically, the mixing assembly 300 includes a support and a mixing body. The mixing body is mounted above the monitoring mechanism via the support, and the drive motor is mounted on the support and connected to the mixing body to drive the mixing body to rotate, thereby mixing the various mineral slurries inside the mixing body.

[0042] The mixing body has different discharge ports 310 below it. Each discharge port 310 is equipped with a discharge valve. When the slurry in the mixing body is mixed, all discharge valves are opened. Driven by the drive motor, the slurry in the mixing body is rotated and thrown out from the discharge port 310, so that the mixed slurry falls into the placement frame. The placement frame has a total discharge port 500 on one side. The mixed slurry is obtained through the total discharge port 500.

[0043] In an optional embodiment, the mixing mechanism further includes a timer connected to the discharge port 310. When the mixing time is reached according to the mixing time standard, the discharge port 310 is opened to discharge the slurry in the mixing body.

[0044] In an optional embodiment, it further includes:

[0045] The cleaning mechanism 600 is connected to the sampler 210, the mixing mechanism and the sampling tank respectively, and is used to clean the sampler 210, the mixing mechanism and the sampling tank.

A cleaning switch is provided between the sampler 210 and the cleaning pipe, between the mixing mechanism and the cleaning pipe, and between the sampling tank and the cleaning pipe.

[0047] Specifically, the cleaning mechanism 600 can clean the sampler 210, the mixing mechanism, and the sampling tank, reducing the mutual interference of the tested slurry.

[0048] The water tank is connected to one end of the cleaning pipe via a booster pump. The other end of the cleaning pipe is connected to the sampler 210, the mixing mechanism, and the sampling tank via a cleaning switch. When the sampler 210, the mixing mechanism, and the sampling tank need to be cleaned, the booster pump and the cleaning valve are activated to clean the equipment. This prevents cross-contamination when switching monitoring materials. At the same time, the equipment is cleaned when it is shut down to prevent the slurry from caking and clogging the equipment, which would affect the next startup monitoring.
