Description

Technical Field

[0001] This application relates to the field of slurry sampling technology, and more particularly to a slurry sampling device. Background Technology

[0002] Currently, slurry samplers are important equipment used in mineral processing to collect slurry samples. Their main function is to periodically or continuously extract representative samples from the slurry stream during the production process for subsequent testing and analysis, providing a basis for adjusting process parameters and optimizing the production process.

[0003] In existing technologies, the sampling tube of a sampler extends into the sampler housing to sample the slurry flowing through it. However, because the slurry contains a large number of solid particles, the sampling tube is subjected to impact and wear during sampling, increasing the gap between the sampling tube and the sampler housing. This causes the slurry to leak out, frequently resulting in leakage problems in the slurry sampler. Leakage not only causes slurry loss and environmental pollution but may also affect the accuracy of the sampling data, thus impacting the judgment and optimization decisions regarding the mineral processing technology. Therefore, the leakage problem of slurry samplers urgently needs to be solved. Summary of the Invention

[0004] This application provides a slurry sampling device, including: a shell, with a first port and a second port respectively provided at both ends of the shell along the axial direction, the first port communicating with the second port, and a first through hole provided on the side wall of the shell, and the first through hole communicating with the interior of the shell;

[0005] The sampling tube is clearance-fitted with the first through hole, allowing it to slide within the first through hole, and the first end of the sampling tube is located inside the housing.

[0006] A sealing element is provided at the first end of the sampling tube. When the sampling tube is in the first position, the sealing element abuts against the inner wall of the housing. The sealing element blocks the first through hole inside the housing to seal the gap between the sampling tube and the first through hole.

[0007] In some embodiments, the sealing element is plate-shaped and disposed on the end face of the first end of the sampling tube, and the area of ​​the surface of the sealing element facing the sampling tube is larger than the area of ​​the end face of the first end of the sampling tube.

[0008] The sealing element includes a reinforcing part and a sealing part. The reinforcing part is provided corresponding to the end face of the first end, and the sealing part is provided around the reinforcing part. The sealing part is used to seal the gap.

[0009] In some embodiments, the inner sidewall of the housing is provided with a receiving groove, which surrounds the first through hole;

[0010] The seal is adapted to the receiving groove, and the seal can be embedded in the receiving groove. When the sampling tube is in the first position, the seal fills the receiving groove, and the face of the seal facing the inside of the housing is coplanar with the inner surface of the housing.

[0011] In some embodiments, the depth of the receiving groove gradually increases from the axis of the first through hole to the outer periphery of the first through hole, and the seal is adapted to the receiving groove.

[0012] In some embodiments, it further includes: an elastic sealing ring, which is embedded in the port of the first through hole near the inner sidewall of the housing.

[0013] In some embodiments, a sampling port is provided on the side wall of the sampling tube, the sampling port is disposed near the sealing element, and the sampling port faces the first port.

[0014] In some embodiments, the sampling port is a strip-shaped port, and the length direction of the strip-shaped port is consistent with the axial direction of the first port.

[0015] In some embodiments, a guide member is disposed on the outer side wall of the housing, and the guide member is provided with a second through hole, which communicates with and is coaxially disposed with the first through hole, so that the sampling tube moves along the second through hole of the guide member.

[0016] In some embodiments, a driving component is also included, which is disposed in the housing and connected to the sampling tube for driving the sampling tube to slide back and forth within the first through hole.

[0017] In some embodiments, the drive assembly includes a geared motor, and the output end of the geared motor is provided with two gears spaced apart.

[0018] Two drive gears are mounted on the housing via a rotating shaft and are meshed with a reduction gear.

[0019] The connecting frame includes two connectors and a mounting platform. The two connectors are rotatably mounted on the side wall of the drive gear and are eccentrically positioned relative to the shaft.

[0020] The mounting platform is rotatably positioned between the two connectors and rotatably connected to the other end of the two connectors;

[0021] The mounting platform is equipped with assembly holes, through which the sampling tube passes and is fixedly connected to the mounting platform.

[0022] Compared with existing technologies, this slurry sampling device, by installing a sealing element at the first end of the sampling tube, effectively seals the gap between the sampling tube and the shell when the sampling tube is in the first position, as the sealing element tightly abuts against the inner wall of the shell, blocking the first through hole and preventing slurry leakage. This structure not only improves the leak-proof performance of the device but also enhances sampling accuracy and operational safety. Furthermore, its simple structure facilitates maintenance and makes it suitable for various complex working conditions, demonstrating significant engineering application value.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. The term "two or more" includes two or more cases.

[0037] like Figure 1-5 As shown, a slurry sampling device includes: a housing 10, with a first port 11 and a second port 12 respectively provided at both ends of the housing 10 along its axial direction, the first port 11 and the second port 12 communicating with each other, and a first through hole provided on the side wall of the housing 10, and the first through hole communicating with the interior of the housing 10.

[0038] The sampling tube 20 is clearance-fitted with the first through hole, and the sampling tube 20 can slide within the first through hole, with the first end of the sampling tube 20 located inside the housing 10.

[0039] A sealing element 30 is provided at the first end of the sampling tube 20. When the sampling tube 20 is in the first position, the sealing element 30 abuts against the inner wall of the housing 10. The sealing element 30 blocks the first through hole inside the housing 10 to seal the gap between the sampling tube 20 and the first through hole.

[0040] Understandably, the shell 10 is a hollow structure with a first port 11 and a second port 12 at its two axial ends, respectively, for connecting to the slurry conveying pipeline so that the slurry flows through the interior of the shell 10. A first through hole is provided on the side wall of the shell 10 and communicates with the interior of the shell 10 for inserting the sampling tube 20.

[0041] The sampling tube 20 is a slender tube that can be slidably inserted into the housing 10. One end (referred to as the first end) extends into the housing 10, and the other end is located outside the housing 10. It is used to connect to a sampling container or collection device.

[0042] The sampling tube 20 is clearance-fitted with the first through hole on the housing 10, allowing the sampling tube 20 to slide axially within the through hole.

[0043] The sealing element 30 is located at the first end of the sampling tube 20, that is, the end that extends into the housing 10. It can be made of corrosion-resistant and wear-resistant materials, such as polytetrafluoroethylene (PTFE) or rubber-coated metal skeleton.

[0044] like Figure 1 As shown, when the sampling tube 20 is in the first position, that is, when sampling is completed or not in the sampling state, the sealing element 30 is in close contact with the inner wall of the housing 10 to form an effective seal, blocking the gap between the first through hole and the sampling tube 20, and preventing slurry leakage.

[0045] An oil seal is provided between the sampling tube 20 and the housing 10 to form a second seal. The oil seal is installed at the edge of the first through hole of the housing 10 and is arranged around the sampling tube 20. It maintains a dynamic seal as the sampling tube 20 slides.

[0046] In some embodiments, the sealing member 30 is plate-shaped and disposed on the end face of the first end of the sampling tube 20, and the area of ​​the surface of the sealing member 30 facing the sampling tube 20 is greater than the area of ​​the end face of the first end of the sampling tube 20.

[0047] The sealing element 30 includes a reinforcing part 31 and a sealing part 32. The reinforcing part 31 is disposed corresponding to the end face of the first end, and the sealing part 32 is disposed around the reinforcing part 31. The sealing part 32 is used to seal the gap.

[0048] Understandably, the mounting surface of the seal 30, i.e. the side connected to the sampling tube 20, is larger than the end face of the sampling tube 20, so that the seal 30 can partially extend to the outer periphery of the sampling tube 20, increasing the sealing area. The seal 30 can cover the gap between the outer wall of the sampling tube 20 and the inner wall of the first through hole from the inside of the housing 10, and at the same time, it is also beneficial to form a larger contact area between the seal 30 and the inner wall of the housing 10.

[0049] The reinforcing part 31 is fitted to the end face of the first end of the sampling tube 20, providing structural support, enhancing the overall rigidity of the sealing element 30, bearing the pressure and impact from the flow of slurry, forming a reinforced protection for the end of the first end of the sampling tube 20, and reducing the impact wear of the slurry.

[0050] The reinforcement part 31 can be made of metal, such as stainless steel, carbon steel or high-strength engineering plastics (such as POM, PEEK) and other materials with certain hardness and wear resistance. The surface can be treated with anti-corrosion treatment (such as electroplating, spraying ceramic coating, etc.) to adapt to different mineral slurry media environments.

[0051] The sealing part 32 is arranged around the reinforcing part 31 to form an annular sealing edge, which is used to fit tightly against the inner wall of the housing 10 and seal the gap between the sampling tube 20 and the housing 10. In the first position, that is, in the non-sampling state, it can effectively block the leakage of slurry from the first through hole.

[0052] The sealing part 32 has good elasticity and resilience, and can adapt to minor unevenness or displacement of the inner wall of the housing 10 within a certain range. It can be made of corrosion-resistant, wear-resistant and flexible materials, such as fluororubber (FKM), polytetrafluoroethylene (PTFE), silicone rubber, polyurethane, etc.

[0053] In some embodiments, the inner sidewall of the housing 10 is provided with a receiving groove 13, which surrounds the first through hole;

[0054] The seal 30 is adapted to the receiving groove 13 and can be embedded in the receiving groove 13. When the sampling tube 20 is in the first position, the seal 30 fills the receiving groove 13. The surface of the seal 30 facing the inside of the housing 10 is coplanar with the inner surface of the housing 10.

[0055] Understandably, in order to improve the positioning accuracy and sealing reliability of the seal 30, a receiving groove 13 is provided on the inner side wall of the housing 10, and the receiving groove 13 is adapted to the seal 30.

[0056] The receiving groove 13 is provided on the inner wall of the housing 10, surrounding the first through hole, and its size and shape match the seal 30 to ensure that the seal 30 can be fully embedded therein, avoiding any displacement or loosening.

[0057] The depth of the receiving groove 13 is set according to the thickness of the seal 30 to ensure that the surface of the seal 30 after it is embedded is coplanar with the inner surface of the housing 10.

[0058] The sampling tube 20 is in the first position, and the seal 30 is fully embedded in the receiving groove 13 of the housing 10. The surface of the seal 30 is coplanar with the inner surface of the housing 10.

[0059] At this point, the seal 30 effectively seals the first through hole, preventing the slurry from overflowing from the gap between the sampling tube 20 and the housing 10.

[0060] By setting the receiving groove 13, the seal 30 is precisely positioned, avoiding the problem of misalignment or loosening during use. After the seal 30 is embedded in the receiving groove 13, it not only fills the gap but also forms a complete sealing barrier, enhancing the overall sealing performance. The surface of the seal 30 is coplanar with the inner surface of the housing 10, reducing fluid resistance and lowering the risk of turbulence caused by local protrusions, which is conducive to maintaining the smooth flow of the slurry.

[0061] In some embodiments, the depth of the receiving groove 13 gradually increases from the axis of the first through hole to the outer periphery of the first through hole, and the seal 30 is adapted to the receiving groove 13.

[0062] Understandably, the receiving groove 13 is disposed on the inner wall of the housing 10, arranged around the first through hole, and gradually deepens from the axis of the first through hole outward. That is, the receiving groove 13 is shallower near the insertion center of the sampling tube 20 (i.e., the axis of the first through hole); and gradually becomes deeper as it extends towards the circumference of the housing 10.

[0063] The sealing element 30 is a plate-shaped structure, and its outline must match the shape of the receiving groove 13 to achieve complete embedding.

[0064] The thickness or cross-sectional shape of the seal 30 also exhibits a corresponding inclined transition or stepped change to ensure smooth insertion and conformity to the entire surface of the receiving groove 13. In the non-sampling state, the seal 30 can be fully embedded in the receiving groove 13, so that the side of the seal 30 facing the inside of the housing 10 is coplanar with the inner surface of the housing 10, forming a smooth transition.

[0065] The gradual depth design of the receiving groove 13 allows the seal 30 to better adapt to the curvature changes of the inner wall of the housing 10 after being embedded, which is especially suitable for circular or arc-shaped housing 10 structures.

[0066] This helps to improve the tightness of contact between the seal 30 and the inner wall of the housing 10, reducing the risk of leakage due to local gaps.

[0067] The flow of slurry exerts uneven pressure on the seal 30, especially near the insertion point of the sampling tube 20. The progressively deeper receiving groove 13 allows the seal 30 to have a larger support area under pressure, thereby distributing stress more evenly and preventing localized deformation or damage.

[0068] The bottom of the receiving groove 13 can be sloped, tapering outwards from the axis, suitable for wedge-shaped structures of the integral seal 30. The receiving groove 13 can be divided into multiple steps radially, each step corresponding to a different part of the seal 30, achieving segmented embedding. The bottom surface of the receiving groove 13 can have a smooth curved transition, suitable for the fitting and embedding of flexible material seals 30, improving the sealing effect. This progressively deeper receiving groove 13 structure makes it suitable for high-flow-rate, high-pressure slurry systems.

[0069] In some embodiments, an elastic sealing ring 40 is also included, which is embedded in the port of the first through hole near the inner sidewall of the housing 10.

[0070] Understandably, the elastic sealing ring 40 is located at the inner inlet of the connection between the housing 10 and the sampling tube 20, adjacent to the internal space of the housing 10.

[0071] The elastic sealing ring 40 is installed in an embedded manner. An annular groove or stepped structure is machined on the inner edge of the first through hole to accommodate the elastic sealing ring 40. The elastic sealing ring 40 can be partially or completely embedded in the groove to ensure that it will not fall off due to slurry impact or movement of the sampling tube 20. The elastic sealing ring 40 can be made of rubber, silicone, polyurethane, etc.

[0072] After the sampling tube 20 is inserted into the first through hole, the elastic sealing ring 40 fits between the outer wall of the sampling tube 20 and the housing 10, forming a dynamic seal. The elastic sealing ring 40, together with the existing oil seal and plate-shaped seal 30, constitutes a multi-stage sealing system, significantly improving the ability to prevent leakage.

[0073] The fit between the sampling tube 20 and the housing 10 may have manufacturing errors or wear gaps after long-term use. The elastic sealing ring 40 fills these tiny gaps through its own deformation ability, thereby improving the overall sealing stability.

[0074] In some embodiments, such as Figure 3 As shown, a sampling port 21 is provided on the side wall of the sampling tube 20. The sampling port 21 is located near the sealing member 30 and faces the first port 11.

[0075] Understandably, the sampling port 21 is located near the end of the sampling tube 20 that extends into the housing 10 (i.e., the first end), close to the sealing element 30, and the opening direction of the sampling port 21 is towards the first port 11 of the housing 10, i.e., the end in the direction of slurry flow.

[0076] like Figure 2 As shown, during the sampling operation, the first end of the sampling tube 20 extends into the housing 10, and the sampling port 21 is connected to the internal space of the housing 10. The slurry can then enter the inner cavity of the sampling tube 20 through the sampling port 21 to achieve sample collection.

[0077] After sampling is completed, the sampling tube 20 is reset to the first position, and the sealing element 30 is embedded in the receiving groove 13 of the housing 10. At this time, the sampling port 21 is hidden in the first through hole and isolated from the inside of the housing 10 to ensure that there is no slurry leakage.

[0078] In some embodiments, the sampling port 21 is a strip-shaped port, and the length direction of the strip-shaped port is consistent with the axial direction of the first port.

[0079] Understandably, the strip-shaped opening is located on the side wall of the sampling tube 20, near the sealing element 30, and the length direction of the strip-shaped opening is consistent with the axial direction of the first through hole, that is, it extends along the direction in which the sampling tube 20 is inserted into the housing 10.

[0080] Compared to traditional circular or other shaped sampling ports 21, the strip-shaped port has a larger opening area, especially providing a longer opening section along the axial direction of the sampling tube 20. This increases the chance of slurry entering the sampling tube 20 and improves sampling efficiency. The strip-shaped port, arranged along the axial direction of the sampling tube 20, can better capture components at different levels during the slurry flow, thereby improving the representativeness of the collected samples.

[0081] Furthermore, compared to the small-diameter circular sampling port 21, the strip-shaped port is less prone to clogging by large particles in the slurry, making it particularly suitable for slurry environments with high solids content. The strip-shaped port design helps guide the slurry to flow more naturally into the sampling tube 20, reducing turbulence and local pressure loss, and thus helping to maintain the flow stability of the slurry.

[0082] In some embodiments, a guide 50 is disposed on the outer side wall of the housing 10. The guide 50 is provided with a second through hole, which communicates with the first through hole and is coaxially disposed, so that the sampling tube 20 moves along the second through hole of the guide 50.

[0083] Understandably, the guide 50 is mounted on the outer wall of the housing 10 to provide mechanical guidance and support, enabling the sampling tube 20 to smoothly enter and exit the housing 10 along a fixed axial direction during sampling operations.

[0084] The second through hole inside the guide 50 is coaxially set with the first through hole on the housing 10, so that the sampling tube 20 always moves along the same axis during the process of entering and exiting the housing 10, avoiding deviation or jamming, and ensuring the smooth progress of the sampling operation.

[0085] The guide component 50 can be made of a material with a certain degree of flexibility, such as fluororubber (FKM), polytetrafluoroethylene (PTFE), silicone rubber, polyurethane, etc., to reduce the gap between the guide component 50 and the sampling tube 20, preventing the mineral liquid from flowing out when not sampling. An oil seal assembly can be installed on the guide component 50, so that the outer wall of the sampling tube 20 forms a seal with the wall of the second through hole of the guide component 50, achieving a seal when not sampling.

[0086] The oil seal is located inside the guide member 50, specifically at the wall of the second through hole, to ensure that when the sampling tube 20 enters or exits the housing 10, the outer wall of the sampling tube 20 can maintain close contact with the second through hole of the guide member 50 and form a dynamic seal.

[0087] In some embodiments, a drive component 60 is also included. The drive component 60 is disposed in the housing 10 and connected to the sampling tube 20 for driving the sampling tube 20 to slide back and forth in the first through hole.

[0088] Understandably, the drive assembly 60 is mounted on the housing 10, typically located outside the housing 10 or integrated with it. It is directly connected to the sampling tube 20 and drives the sampling tube 20 to reciprocate axially along the first through-hole via mechanical transmission. The drive assembly 60 can employ various driving methods, such as electric drive, pneumatic drive, and hydraulic drive. Electric drive uses a motor to drive a lead screw or rack and pinion mechanism to move the sampling tube 20. Pneumatic drive uses a cylinder to drive the sampling tube 20, suitable for applications requiring rapid response. Hydraulic drive utilizes the pressure of hydraulic oil to drive the sampling tube to reciprocate.

[0089] In some embodiments, the drive assembly 60 includes a geared motor 61, and the output end of the geared motor 61 is provided with two gears 62 spaced apart.

[0090] Two drive gears 63 are mounted on the housing 10 via a rotating shaft and are meshed with a reduction gear 62.

[0091] The connecting frame 70 includes two connectors 71 and a mounting platform 72. The two connectors 71 are rotatably mounted on the side wall of the drive gear 63 and are eccentrically positioned relative to the shaft.

[0092] The mounting platform 72 is rotatably disposed between the two connectors 71 and rotatably connected to the other end of the two connectors 71;

[0093] The mounting platform 72 is provided with an assembly hole, through which the sampling tube 20 passes and is fixedly connected to the mounting platform 72.

[0094] Understandably, the geared motor 61 provides the power source, driving the reciprocating motion of the entire sampling tube 20. Two reduction gears 62 are installed at the output end of the geared motor 61 to transmit power and regulate the speed.

[0095] The rotating shaft is fixed to the housing 10 of the sampling device via a bearing seat. Two drive gears 63 are fixed to the housing 10 via the rotating shaft and mesh with the reduction gear 62, which can convert the rotational motion of the reduction motor 61 into the rotational motion of the drive gear 63, thereby driving the connecting frame 70 to reciprocate.

[0096] Two connecting members 71 of the connecting frame 70 are rotatably mounted on the side wall of the drive gear 63 and are eccentrically positioned with respect to the rotating shaft. The mounting platform 72 is located between the two connecting members 71 and is rotatably connected to the other end of the connecting members 71. When the drive wheel drives the connecting members 71 to rotate, the mounting platform 72 can achieve reciprocating linear motion under the action of the two connecting members 71.

[0097] The mounting platform 72 is provided with an assembly hole. The sampling tube 20 passes through the hole and is fixed to the mounting platform 72. Since the sampling tube 20 passes through the guide member 50, when the connecting member 71 rotates with the drive gear 63, the mounting platform 72 drives the sampling tube 20 to reciprocate along the second through hole in the guide member 50.

[0098] Working process: When the control system issues a sampling command, the geared motor 61 starts working, driving the reduction gear 62 to rotate. The reduction gear 62 drives the drive gear 63 to rotate through a meshing relationship. Since the drive gear 63 is eccentrically connected to the connecting member 71, the rotation of the drive gear 63 causes the connecting member 71 to swing, thereby pushing the mounting platform 72 to move along a predetermined trajectory.

[0099] The mounting platform 72 has a mounting hole for fixing a sampling tube 20. As the mounting platform 72 moves, the sampling tube 20 slides along the second through hole of the guide 50 and gradually detaches from the inner wall of the housing 10, exposing the strip-shaped opening and allowing the slurry to enter the sampling tube 20.

[0100] The second end of the sampling tube 20 is connected to a sampling bucket for collecting slurry samples.
