[0002] In order to monitor product quality and ensure the normal operation of the production process during mineral processing, a small amount of representative slurry needs to be taken from key stages of the process for analysis and research to test the process parameters in mineral processing.

[0003] Currently, most slurry sampling is done manually. During sampling, staff members use sampling tools to extract the slurry. To ensure the accuracy of the sample data, staff members need to take samples every certain period of time. Frequent sampling results in high labor intensity for staff, and the sampling interval cannot be precisely controlled, which can easily lead to inaccurate sample data. Utility Model Content

[0004] To address or partially address the problems existing in related technologies, this utility model provides a DC slurry automatic sampling device, aiming to achieve mechanized automatic sampling, thereby reducing the labor intensity of relevant personnel and improving the accuracy of sampling intervals, thus enhancing the representativeness and accuracy of sample data.

When the first sampling cylinder extends, the discharge port of the feed pipe is located above one of the discharge hoppers; when the first sampling cylinder retracts, the discharge port of the feed pipe is located above the other discharge hopper. The first sampling cylinder is connected to the signal output terminal of the controller, and a timer is connected to the signal input terminal of the controller.

[0006] In some designs, there are two ore distribution boxes, arranged at intervals along the vertical direction; The outlet of one of the discharge hoppers of the upper ore distribution box is connected to a diversion pipe; A second sampling cylinder is provided on the side of the lower ore distribution box, and the lower end of the diversion pipe is fixedly installed on the telescopic rod of the second sampling cylinder.

[0007] In some designs, the shunt tube is a flexible hose.

[0008] In some designs, the ore distribution box is a square box with an open top.

[0009] The technical solution provided by this utility model can include the following beneficial effects: This application enables mechanized sampling of slurry, reducing the labor intensity of workers. At the same time, through the coordinated control of timers and controllers, the sampling process is automated, effectively improving the accuracy of sampling intervals and thus improving the accuracy of sample data.

[0010] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit the present invention. Attached Figure Description

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the scope of protection of the present invention is not limited to the content described. Example 1:

[0015] like Figure 1 and Figure 2 As shown, this application provides a DC slurry automatic sampling device, including a slurry box 1, a discharge hopper 2, a feed pipe 3, and a controller 4.

[0016] The ore sorting box 1 is made of metal and is a square box with an open top. Two conical discharge hoppers 2 are arranged side-by-side at the bottom of the ore sorting box 1. The upper ends of the discharge hoppers 2 are square, and the upper ends of the two discharge hoppers 2 completely cover the bottom of the ore sorting box 1. This ensures that all the slurry in the ore sorting box 1 can flow out through the two discharge hoppers 2. The lower ends of the discharge hoppers 2 are cylindrical, facilitating connection to slurry conveying pipes. For ease of description, the discharge hopper 2 on the left is named Discharge Hopper 1 21, and the discharge hopper 2 on the right is named Discharge Hopper 2 22. A first sampling cylinder 5 is located on the side of the ore sorting box 1. A feed pipe 3 is installed on the telescopic rod of the first sampling cylinder 5. The first sampling cylinder 5 is connected to the signal output terminal of the controller 4, and a timer is connected to the signal input terminal of the controller 4.

[0017] In use, connect the feed end of feed pipe 3 to the slurry conveying tank at the higher position, so that the slurry can flow into feed pipe 3 by gravity; place the sample collection box below the second discharge hopper 22 to collect slurry samples; connect the first discharge hopper 21 to the slurry conveying tank at the lower position through a pipe, so that the slurry discharged from the first discharge hopper 21 can flow back into the slurry conveying tank.

[0018] Under normal conditions, the first sampling cylinder 5 is in a shortened state, and the discharge port of the feed pipe 3 is located above the first discharge hopper 21. At this time, the ore will be introduced into the feed pipe 3 and then flow into the first discharge hopper 21, and then flow back to the slurry conveying tank through the pipeline.

[0019] During sampling, the first sampling cylinder 5 extends, driving the discharge port of the feed pipe 3 to move above the second discharge hopper 22. At this time, the ore will be introduced into the feed pipe 3, then flow into the second discharge hopper 22, and then into the sample collection box, realizing the mechanical and automated sampling of slurry samples, effectively reducing the labor intensity of the staff.

[0020] When continuous interval sampling is required, timer 8 starts timing. When the set sampling time interval is reached, timer 8 transmits a signal to controller 4. Controller 4 controls the first sampling cylinder 5 to extend for sampling. When the sampling time reaches the set time, timer 8 transmits the relevant signal to controller 4 again. Controller 4 controls the first sampling cylinder 5 to shorten. In this way, the accuracy of the sampling interval is effectively ensured, thereby guaranteeing the accuracy of the sample data. At the same time, by setting the sampling time for each time, the number of samples taken each time can be precisely controlled, further ensuring the accuracy of the sample data.

[0021] Implementation: 2:

[0022] Based on Example 1, in this example, as Figure 3As shown, there are two ore distribution boxes 1, which are arranged at intervals in the vertical direction. For ease of description, the discharge hopper 2 on the upper ore distribution box 1 is named discharge hopper 21 (left) and discharge hopper 22 (right); the discharge hopper 2 on the lower ore distribution box 1 is named discharge hopper 23 (left) and discharge hopper 24 (right).

[0023] The outlet of the No. 1 discharge hopper 21 is connected to a diversion pipe 6, which is a flexible hose; a second sampling cylinder 7 is provided on the side of the lower ore distribution box 1, and the lower end of the diversion pipe 6 is fixedly installed on the telescopic rod of the second sampling cylinder 7.

[0024] In use, the feed end of feed pipe 3 is still connected to the slurry conveying tank at the high position, and the discharge end of discharge hopper 23 is connected to the slurry conveying tank at the low position through a pipe.

[0025] Under normal conditions, the first sampling cylinder 5 and the second sampling cylinder 7 are in a shortened state. The slurry is introduced from the feed pipe 3, and then passes through the first discharge hopper 21, the diversion pipe 6, and the third discharge hopper 23 in sequence, and then flows back into the slurry conveying tank through the pipeline.

[0026] During sampling, two sample collection boxes are placed below the No. 2 discharge hopper 22 and the No. 4 discharge hopper 24, respectively. The first sampling cylinder 5 extends, driving the discharge port of the feed pipe 3 to move above the No. 2 discharge hopper 22. At this time, the ore will be introduced into the feed pipe 3, then flow into the No. 2 discharge hopper 22, and then into the sample collection box for the collection of the main sample. After the main sample is collected, the first sampling cylinder 5 shortens, and the slurry flows into the No. 1 discharge hopper 21. At the same time, the second sampling cylinder 7 extends, causing the discharge port of the diversion pipe 6 to move above the No. 4 discharge hopper 24. The slurry flowing out of the diversion pipe 6 flows into the No. 4 discharge hopper 24 and then into the corresponding sample collection box, thereby realizing the collection of the backup sample.

[0027] This embodiment achieves one sample collection and one backup by setting up two sample boxes 1, effectively avoiding the problem of data loss after sample loss or contamination.

[0028] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
