Description

Technical Field

[0001] The utility model relates to the technical field of pulp sampling equipment, in particular to a pulp intercepting and sampling device. Background Art

[0002] Pulp refers to a liquid mixture formed by adding raw materials in solid forms such as ores and mineral soils, as well as water and other auxiliary materials in industrial production to extract target elements. To optimize and control the ore dressing production process, it is necessary to take representative pulp samples at each process link of ore dressing to measure production process parameters such as ore grade, concentration and fineness.

[0003] The samplers used in the ore dressing plant during the pulp sampling process mainly have the following defects: (1) At sampling locations where the pressure of the cyclone underflow or the pipeline outlet is relatively large, the pulp in the connecting pipeline will flow rapidly from the inside of the discharge pipe, resulting in splashing of the pulp everywhere and affecting the sampling effect; (2) At sampling locations where the pulp flow rate is large, currently during the sampling process, the manual sampler used has one end open and the other end closed. When it is placed into the pulp flow, it needs to stay for a certain time to allow the pulp to enter the sampler to reach the sampling volume. However, the time that the sampler stays in the pulp flow will cause the materials in the pulp to quickly accumulate in the sampler and overflow after the liquid is full, resulting in a relatively high concentration of the sampled sample and lack of representativeness; (3) At sampling locations where the pulp flow rate is large and the sampling distance is relatively far, it is difficult to hold the manual sampler steadily, resulting in spillage of the pulp. (4) When a large amount of samples are needed, the existing samplers have a small sampling volume and it is difficult to obtain a large amount of samples.

[0004] Therefore, it has become an urgent problem in this field to develop a set of pulp intercepting samplers that can overcome the above defects. Summary of the Utility Model

Specific embodiments

[0023] In order to better explain the present utility model, the main content of the present utility model is further clarified below in conjunction with specific embodiments, but the content of the present utility model is not limited to the following embodiments.

[0024] As Figures 1 to 4 shown is a slurry intercepting and sampling device of the present utility model, which includes a cylindrical sampler. The cylindrical sampler is vertically through, including a cylindrical sampling tube 1 in the upper part and a flexible hose 2 in the lower part. The sampling tube 1 and the flexible hose 2 can be integrally arranged. A circular slurry sampling port 101 is opened at the top of the sampling tube 1, and the bottom of the sampling tube 1 is connected to the top of the flexible hose 2. The bottom of the flexible hose 2 is provided with a discharge port and leads into the sampling bucket 4. A sampling rod 3 is fixedly connected to the side of the sampling tube 1. Through the cooperation of the sampling tube 1, the flexible hose 2, the sampling rod 3 and the sampling bucket 4, the slurry sample is taken at the slurry sampling port 18 through the sampling tube 1 and transported to the sampling bucket 4 through the flexible hose 2, avoiding the problem of slurry splashing everywhere.

[0025] A diagonal brace is also arranged between the sampling tube 1 and the sampling rod 3 to improve the stability between the sampling tube 1 and the sampling rod 3.

[0026] In a specific embodiment, the diameter of the slurry sampling port 101 is 40 mm and the height is 300 mm, and the length of the flexible hose 2 is 2 m.

[0027] In another specific embodiment, the diameter of the pulp sampling port 101 is 50 mm, the height is 350 mm, the length of the hose 2 is 4 m, and the sampling rod 3 is a telescopic adjustable rod; the length of the telescopic adjustable rod is 1.5 m, and the expansion ratio is 1:1. In this way, the length of the sampling rod 3 can be freely changed according to the size of the sampling point space.

[0028] The above-mentioned pulp interception sampling device further includes a driving device, which includes a motor 8, a turntable 5, and a driving rod vertically arranged on the turntable 5. The motor 8 is arranged inside the motor housing 801. The driving rod is divided into two relatively rotatable inner and outer layers: an outer tube 7 and an inner rod 6; a bearing 10 is used to connect the outer tube 7 and the inner rod 6 to reduce the friction between the outer tube 7 and the inner rod 6 during relative rotation, making the relative rotation process of the outer tube 7 and the inner rod 6 smoother and ensuring more stable relative rotation; the top of the outer tube 7 is closed, and a ball 11 is used to connect the top of the outer tube 7 and the top of the inner rod 6. The outer tube 7 is fixedly connected to the sampling rod 3, and a diagonal brace is arranged between the outer tube 7 and the sampling rod 3. The turntable 5 is arranged above the motor 8, the motor 8 drives the turntable 5 to rotate, and the bottom end of the inner rod 6 is fixedly arranged on the turntable 5. The inner rod 6 drives the outer tube 7 to make a circular motion around the center of the turntable 5. Then, the outer tube 7 drives the sampling rod 3, and the sampling rod 3 drives the sampling tube 1 to make a circular motion below the pulp sampling port 18, continuously obtaining pulp samples at different positions of the pulp sampling port 18, improving the uniformity and representativeness of the obtained pulp samples.

[0029] The pulp interception sampling device is driven by a motor, which can save manpower and operate stably.

[0030] The above-mentioned turntable 5 is also provided with a turntable track 9 for adjusting the rotation radius of the inner rod 6. The bottom end of the inner rod 6 is fixedly arranged in the turntable track 9, and the fixed position of the inner rod 6 in the turntable track 9 can be adjusted to adjust the rotation radius of the driving rod. Specifically, the inner rod 6 can be clamped at different positions in the turntable track 9 by setting multiple slots on the turntable track 9, or the inner rod 6 can be fixed at different positions on the turntable track 9 by means of bolt and nut connection to adjust the rotation radius of the driving rod on the turntable 5. In this way, the rotation radius can be adjusted according to the cross-sectional radius of the pulp pipeline at the sampling point.

[0031] The above slurry intercepting and sampling device is also provided with a limiting device. The limiting device includes a fixed rod 12, a sliding rod 13, and a limiting mechanism 15. The fixed rod 12 is L-shaped and is provided with a brace thereon. The right end of the fixed rod 12 is fixedly connected to the motor housing 801, and the other end is rotatably connected to the sliding rod 13 through a first rotating shaft 14, enabling the sliding rod 13 to rotate relative to the fixed rod 12 with the first rotating shaft 14 as the center; the sliding rod 13 is connected to the sampling rod 3 through the limiting mechanism 15. The limiting mechanism 15 is fixedly connected to the sliding rod 13, and the position where the limiting mechanism 15 is connected to the sliding rod 13 can be adjusted by means of clamping or bolt-nut connection to adjust the distance between the limiting mechanism 15 and the fixed rod 12, so as to match the rotation radius of the inner rod 6 on the turntable track 9.

[0032] As Figures 3 to 4 shown, the limiting mechanism 15 includes a limiting ring 16 and a second rotating shaft 17. The limiting ring 16 is sleeved on the sampling rod 3; the limiting ring 16 is rotatably connected to the sliding rod 13 through the second rotating shaft 17, and the second rotating shaft 17 enables the sliding rod 13 to rotate relative to the sampling rod 3.

[0033] During the actual operation process, when the sampling rod 3 rotates with the outer tube 7, the limiting device can keep the direction of the sampling rod 3 unchanged, and the sliding rod 13 can adjust the rotation radius so that the rotation radius of the sampling rod 3 is the same as that of the inner rod 6 when it rotates.

[0034] Other parts not described belong to the prior art.
