To ensure the accuracy of the sample data, staff members need to take samples every certain period of time. This frequent sampling results in high labor intensity for staff members and requires at least two staff members to take turns sampling, which increases the production costs of enterprises.

[0015] 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.

[0016] like Figure 1 and Figure 2 As shown, this application provides a box-type slurry reduction and sampling device, including a slurry tank 1, a reduction and collection box 2, and a sampling hopper 3; the left end of the slurry tank 1 is provided with a slurry feed trough 11, and the other end is provided with a slurry discharge pipe 12.

[0017] A reducing and collecting box 2 is located diagonally to the upper right of the discharge end of the slurry feed trough 11; a sample feed trough 4 is located on the side of the reducing and collecting box 2 near the slurry feed trough 11. One end of the sample feed trough 4 is connected to the reducing and collecting box 2, and the other end is directly opposite the discharge end of the slurry feed trough 11. Thus, after the slurry is ejected from the slurry feed trough 11, part of the slurry flows into the reducing and collecting box 2 along the sample feed trough 4 under the action of inertia, while most of the slurry overflows from the sample feed trough 4 and flows into the slurry tank 1. (Note: Figure 1 For illustrative purposes only, the tilt angle of the sample feed trough 4 in the diagram may not be accurate. In actual use, those skilled in the art should realize that the tilt angle of the sample feed trough 4 should be set according to the slurry flow rate. A faster slurry flow rate requires a larger tilt angle, and a slower slurry flow rate requires a correspondingly smaller tilt angle, to ensure that a small amount of slurry can flow into the fractionation collection box 2 along the sample feed trough 4. The right side of the sample collection box 2 is provided with a sample discharge pipe 21; the right side of the sample collection box 2 is provided with a drive mechanism 5, and the drive mechanism 5 is provided with a sampling hopper 3.

[0018] When in use, install the device at the location where sampling is required, and connect the slurry feed trough 11 to the upstream of the slurry conveying pipeline; connect the slurry discharge pipe 12 to the downstream of the slurry conveying pipeline; and connect the discharge end of the sampling hopper 3 to the container holding the slurry sample through a hose.

[0019] When not sampling, the sampling hopper 3 is not located directly below the sample discharge pipe 21, so that the slurry will not flow into the sampling hopper 3; the slurry is introduced into the slurry tank 1 from the slurry feed trough 11, and at the discharge end of the slurry feed trough 11, a small portion of the slurry flows along the sample feed trough 4 to the fractionation collection box 2, forming a fractionation sampling of the slurry, and then flows out from the sample discharge pipe 21 to the slurry tank 1; most of the slurry flows into the slurry tank 1, and the slurry in the slurry tank 1 finally flows out from the slurry discharge pipe 12.

[0020] During sampling, the drive mechanism 5 is activated, causing the sampling hopper 3 to move and sweep directly below the sample discharge pipe 21. When the sampling hopper 3 passes directly below the sample discharge pipe 21, the slurry flowing from the sample discharge pipe 21 flows into the sampling hopper 3, and then flows through the hose into the container holding the slurry sample, thereby realizing the slurry sampling work.

[0021] This application enables automated sampling of slurry samples, saving on personnel input and thus reducing the company's production costs, while also reducing the labor intensity of relevant staff.

[0022] In this embodiment, the driving mechanism 5 includes a guide rod 51, a slider 52, a mounting rod 53, and a cylinder 54.

[0023] There are two guide rods 51, which are arranged parallel to each other and along the length of the reducing collection box 2. Both ends of the guide rods 51 are fixedly installed on the side wall of the slurry tank 1. The slider 52 has two mounting holes through which the two guide rods 51 pass, allowing the slider 52 to move along the guide rods 51. A cylinder 54 is installed on the side wall of the slurry tank 1. The telescopic rod of the cylinder 54 passes through the side wall of the slurry tank 1 and is fixedly connected to the slider 52. When the cylinder 54 is activated, it drives the slider 52 to move along the guide rods 51. An mounting rod 53 is provided on the slider 52, and the sampling bucket 3 is fixedly installed on the mounting rod 53.

[0024] During sampling, the cylinder 54 is activated, driving the slider 52 to move along the guide rod 51. The slider 52 drives the sampling bucket 3 to move via the mounting rod 53, so that the sampling bucket 3 passes directly below the sample discharge pipe 21 for sampling. By installing the cylinder 54 at a high position, this application can reduce the corrosion of the cylinder 54 by the slurry water mist, thereby extending the service life of the cylinder 54.

[0025] In some specific embodiments, the inner wall of the slurry tank 1 is covered with ceramic tiles, which can effectively prevent the slurry from wearing down the slurry tank 1 over a long period of time, thereby improving the service life of the device. At the same time, since the surface of the ceramic tiles is relatively smooth, it is not easy for them to become clogged.

[0026] In some specific implementations, such as Figure 3 As shown, the cylinder 54 is covered with a protective cover 55, which further protects the cylinder 54, effectively reducing the corrosion of the cylinder 54 by the slurry water mist, thereby extending the service life of the cylinder 54.

[0027] In some specific implementations, such as Figure 4As shown, the cylinder 54 is electrically connected to the signal output terminal of the controller 6. Specifically, the controller 6 is a PLC, and the controller 6 is connected to the control valve of the cylinder 54. The signal input terminal of the controller 6 is connected to a timer 7. During operation, the timer 7 keeps time and transmits a signal to the controller 6 at regular intervals. The controller 6 controls the cylinder 54 to extend or retract according to the input signal, so that the sampling hopper 3 sweeps across the bottom of the sample discharge pipe 21 once, i.e., sampling once. In this way, precise control of the sampling interval is achieved, which helps to improve the accuracy of sample data.

[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.
