Abstract
Description
Technical Field
[0001] This utility model relates to the field of slurry sampling technology, specifically a sampler for slurry pipelines. Background Technology
[0002] A slurry pipeline sampler is a device used to sample slurry during transportation, widely used in mining, metallurgy, and chemical industries. Slurry refers to a mixture of solid particles and liquid. Especially in the mining industry, the composition, concentration, and flow properties of slurry have a significant impact on the production process. Therefore, timely and accurate slurry sampling for component analysis and quality control is crucial for ensuring production efficiency and product quality. Due to the blasting process in mining, residual detonating cord casings remain in the ore. Over time, these casings accumulate and clog the sampling blades of the slurry sampler, preventing slurry flow and sample collection. To address this, we propose a sampler for use on slurry pipelines. Utility Model Content
[0003] The purpose of this invention is to provide a sampler for slurry pipelines to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a sampler for a slurry pipeline, comprising a slurry pipe, wherein a port and a sample output port are respectively provided at the top and bottom of the slurry pipe, the port and the sample output port are concentrically distributed, and both the port and the sample output port are perpendicular to the surface of the slurry pipe, the sample output port is used to connect to a sample output pipe, a sampling knife is inserted inside the slurry pipe, the sampling knife includes a sampling tube inserted inside the port, the sampling tube is configured as a cylindrical tube and has a sampling cavity inside, a sampling port is provided on the surface of the sampling tube, the top and bottom of the sampling port are configured as arc-shaped structures and are connected to the inside of the sampling cavity, the sampling cavity is sampled through the sampling port, both the upper and lower ends of the sampling tube are configured as open, and the lower end opening of the sampling tube is connected to the bottom of the sample output port.
[0005] Preferably, a vent valve is installed at the upper opening of the sampling tube.
[0006] Preferably, the upper outer surface of the sampling tube is provided with a threaded section, and a threaded sleeve is threadedly installed on the outer surface of the sampling tube through the threaded section. The diameter of the threaded sleeve is larger than the diameter of the insertion port, and the threaded sleeve is abutted against the top of the insertion port and used to limit the position of the threaded section.
[0007] Compared with the prior art, the beneficial effects of this utility model are:
[0008] 1. This solution utilizes the structural design of the sampling knife. After the sampling knife is inserted into the slurry tube, the sampling port is aligned with the direction of the slurry source in the slurry tube. The slurry will enter the sampling chamber through the sampling port, thus achieving the sampling operation of the slurry sample. The slurry will come into contact with the inner wall of the sampling chamber and, under the action of pressure, will collide with the inner wall of the sampling chamber and generate strong turbulence. The turbulence direction is both vertical and horizontal, which further has a certain mixing effect on the slurry in the sampling chamber, alleviating the stratification caused by sedimentation during the slurry flow, and making the sample more representative.
[0009] 2. This solution uses an open-ended sampling tube at both ends. The lower end of the sampling tube is connected to the sample output port, so that after the slurry sample enters the sampling chamber, it will be directly output through the sample output port, thereby realizing continuous sampling by the sampling knife inside the slurry tube.
[0010] 3. This solution uses a quick-connect installation and fixation method for the sampling knife, which makes the device easy to disassemble and install during use, facilitates cleaning and maintenance during use, and makes it easy to carry. Attached Figure Description

[0014] Example: Please refer to Figure 1-2 This embodiment provides a technical solution: a sampler for a slurry pipe. The surface of the slurry pipe 2 is provided with a socket 3 and a sample output port 4, which are concentrically distributed and perpendicular to the surface of the slurry pipe 2. In use, the sampling blade 1 is inserted into the slurry pipe 2 through the socket 3, and the lower end of the sampling blade 1 penetrates the slurry pipe 2 and enters the sample output port 4. The sample output port 4 connects to a slurry sample output pipe, further enabling continuous sampling by the sampling blade 1 inside the slurry pipe 2, and the sampled slurry is then delivered through the sample output port 4.
[0015] The sampling knife 1 includes a sampling tube 11 inserted into the insertion port 3. The sampling tube 11 is cylindrical and has a sampling chamber 12 inside for storing the sampled slurry. The surface of the sampling tube 11 has a sampling port 13, which is arc-shaped and communicates with the inside of the sampling chamber 12. In use, the sampling tube 11 is inserted into the insertion port 3, and the sampling port 13 is inserted into the slurry pipe 2 facing the direction of the slurry source. When the slurry flows inside the slurry pipe 2, some of the slurry flows directly towards the sampling port 13 and enters the sampling chamber 12 through the sampling port 13, thus achieving the sampling operation of the slurry sample.
[0016] The sampling tube 11 is open at both ends. A vent valve 14 is installed at the upper end of the sampling tube 11. When the sampling tube 11 is inserted into the port 3, the vent valve 14 remains outside the port 3. When sampling slurry samples from inside the sampling tube 11, the vent valve 14 can adjust the internal air pressure of the sampling chamber 12 to prevent the slurry from being unable to enter the slurry tube 2 due to insufficient air pressure inside the sampling chamber 12. This allows the sampling knife 1 to adjust according to the pressure inside the slurry tube 2 to successfully obtain samples.
[0017] The upper surface of the sampling tube 11 is provided with a threaded section 15. A threaded sleeve 16 is threadedly installed on the outer surface of the sampling tube 11 through the threaded section 15. The diameter of the threaded sleeve 16 is larger than the diameter of the socket 3. When the sampling knife 1 is in use, the installation height of the threaded sleeve 16 on the sampling tube 11 can be adjusted by rotating the threaded sleeve 16 on the surface of the threaded section 15. Furthermore, after the sampling tube 11 is inserted into the socket 3, the threaded sleeve 16 will abut against the upper opening of the socket 3 by utilizing the self-locking principle of the thread, and fix the position of the sampling tube 11. This further realizes the adjustment of the insertion depth of the sampling tube 11, which is convenient for adjusting the insertion depth of the sampling knife 1 into the slurry pipe 2 according to the actual situation on site, and improves the convenience of sampling.
[0018] Furthermore, when the slurry enters the sampling chamber 12 through the sampling port 13, the slurry will come into contact with the inner wall of the sampling chamber 12. Under the action of pressure, it will collide with the inner wall of the sampling chamber 12 and generate strong turbulence. The direction of the turbulence is both up and down, which further has a certain mixing effect on the slurry in the sampling chamber 12, alleviates the stratification caused by sedimentation during the flow of the slurry, and makes the sample more representative.
[0019] The device is fixed by quick-connect installation of the sampling blade 1, which makes it easy to disassemble and install during use, facilitates cleaning and maintenance during use, and is easy to carry.
