Description

Technical Field

[0001] This utility model relates to the field of slurry sampling technology, specifically a sampling tool for preventing slurry settling during the slurry sampling process. Background Technology

[0002] In industrial production processes such as mineral processing and metallurgy, accurate determination of slurry concentration is crucial for process control and optimization. Routine sampling typically requires locations where the slurry flow is stable and representative, strictly adhering to the basic principles of randomness, uniformity, and equal quantity to minimize sampling errors.

[0003] Currently, most common slurry sampling methods involve manual sampling spoons or buckets. However, in practical applications, it has been found that when the sampling spoon is inserted into the slurry, the solid mineral particles, being a solid-liquid two-phase mixture, will settle due to gravity, whether in a static or moving state. This phenomenon is particularly pronounced when the mineral particles are coarse or the concentration is high. This settling causes stratification of the slurry within the sampling spoon, with densely packed solid particles at the bottom. This results in a loss of representativeness for the slurry sample, and the compacted slurry is often difficult to pour out, complicating subsequent concentration measurements and directly affecting the accuracy and reliability of the results. Therefore, we propose a sampling tool to prevent slurry settling during the sampling process. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a sampling tool for preventing slurry settling during slurry sampling, comprising: a mounting plate, a motor fixed to the top of the mounting plate by bolts, a square sleeve fixed to the bottom of the mounting plate, a sampling bucket fixed to the bottom of the sleeve, a rotating shaft penetrating through the central hole of the sleeve, the top end of the rotating shaft being coaxially and fixedly connected to the output shaft of the motor, a stirring rod fixedly connected to the bottom end of the rotating shaft, several sets of sliders slidably connected to the body of the sleeve, a connecting block fixed to one side of the sliders, an operating rod fixed to the outer side of the connecting blocks, an insertion hole at the top end of the operating rod, a sealing gasket fixed to the body of the operating rod, a bottom cover fixed to the bottom end of the operating rod, an installation groove inside one side of the mounting plate, a spring fixed inside the installation groove, a limit block fixed to the right side of the spring, a pin fixed to the right end of the limit block, and a push rod fixed to the middle of the top end of the pin.

[0005] As a preferred embodiment of this utility model, the top of the mounting plate is provided with a sliding groove, the push rod is slidably connected to the sliding groove, and the right end of the spring is provided with a round hole that matches the pin, and the pin is slidably connected to the round hole.

[0006] In a preferred embodiment of this utility model, one end of the spring is fixed to the inner wall of the mounting groove, and the other end of the spring is fixed to the limiting block, wherein the limiting block is slidably connected to the inner wall of the mounting groove.

[0007] As a preferred embodiment of this utility model, the bottom end of the rotating shaft extends into the interior of the sampling barrel, and the stirring rod is located in the lower part of the inner cavity of the sampling barrel.

[0008] As a preferred embodiment of this utility model, the operating rod is slidably connected to the sampling bucket, and several sets of air vents are provided on both sides of the connection between the operating rod and the sampling bucket.

[0009] As a preferred embodiment of this utility model, the top end of the operating lever is set in an arc shape, and its arc-shaped end face matches the lateral end of the pin.

[0010] As a preferred embodiment of this utility model, a handle is fixed to the right side of the top end of the operating rod, and a sealing ring is fixed to the mating surface of the bottom cover and the sampling bucket.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) Solve the problem of slurry settling and ensure the representativeness of sampling: The stirring mechanism composed of motor shaft stirring rod can start stirring as needed after sampling. The stirring rod is located in the lower part of the inner cavity of the sampling bucket and can directly act on the area where solid particles that are easy to settle accumulate, effectively breaking the settling stratification and ensuring that the slurry remains uniform before testing. Combined with the design of the bottom opening cover, it ensures that the slurry is poured out smoothly without residue, which improves the accuracy and reliability of testing.

[0013] (2) Optimize the sampling sealing structure to avoid sampling errors and leakage: During the sampling stage, the combination of "opening the bottom cover for sampling + venting the air outlet" avoids the "false fullness" phenomenon caused by the inability of air to be discharged from the sampling bucket, ensuring that the slurry can fill the inner cavity of the sampling bucket, the sampling amount is stable, and the error caused by insufficient or uneven sampling amount is reduced. In the initial state and after sampling, the double sealing structure of "sealing gasket to block the air outlet + bottom cover + sealing ring to seal the bottom end" is used to avoid the leakage of slurry or the entry of external impurities during the sampling process, and at the same time prevents the slurry from spilling during the extraction process after sampling, ensuring the purity of the sample and the cleanliness of the operating environment.

[0014] (3) Convenient and efficient operation, reducing labor costs: The elastic locking mechanism composed of "push rod-pin-spring" can unlock the operating rod by simply pushing the push rod. When resetting, the locking is automatically triggered by the arc end face, eliminating the need for complicated operations and reducing the difficulty of manual operation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example

[0026] Please see Figure 1-6This utility model provides the following technical solution: a sampling tool for preventing slurry sedimentation during slurry sampling, comprising: a mounting plate 1, a motor 2 fixed to the top of the mounting plate 1 by bolts, a square sleeve 3 fixed to the bottom of the mounting plate 1, a sampling bucket 6 fixed to the bottom of the sleeve 3, a rotating shaft 4 penetrating through the central hole of the sleeve 3, the top end of the rotating shaft 4 being coaxially and fixedly connected to the output shaft of the motor 2, a stirring rod 5 fixedly connected to the bottom end of the rotating shaft 4, and several sets of sliders 7 slidably connected to the body of the sleeve 3. A connecting block 8 is fixed to one side of the slider 7, and an operating rod 9 is fixed to the outer side of the connecting block 8. An insertion hole 15 is provided at the top end of the operating rod 9. A sealing gasket 10 is fixed to the body of the operating rod 9, and a bottom cover 11 is fixed to the bottom end of the operating rod 9. An installation groove 16 is provided inside one side of the mounting plate 1. A spring 17 is fixed inside the installation groove 16. A limit block 20 is fixed to the right side of the spring 17. A pin 18 is fixed to the right end of the limit block 20. A push rod 21 is fixed to the middle of the top end of the pin 18.

[0027] To ensure that the push rod 21 slides stably along a fixed trajectory, and to limit the movement direction of the pin 18 to prevent the pin 18 from deviating during left and right movement, thus ensuring the precise docking of the pin 18 and the socket 15, and thereby achieving reliable operation of the locking and unlocking function of the operating lever 9, in this embodiment, as a preferred technical solution of the present invention, a sliding groove 19 is provided at the top of the mounting plate 1, the push rod 21 is slidably connected to the sliding groove 19, and a round hole that matches the pin 18 is provided at the right end of the spring 17, and the pin 18 is slidably connected to the round hole.

[0028] In order to ensure that the spring 17 can be stably fixed in the mounting groove 16, and at the same time, the elastic force of the spring 17 is evenly transmitted to the pin 18 through the limiting block 20, so as to ensure that the pin 18 can move smoothly along the inner wall of the mounting groove 16 under the action of the spring 17, and to avoid the spring 17 from deviating and causing uneven force on the pin 18, thus ensuring the normal operation of the locking mechanism, in this embodiment, as a preferred technical solution of the present invention, one end of the spring 17 is fixed to the inner wall of the mounting groove 16, and the other end of the spring 17 is fixed to the limiting block 20, and the limiting block 20 is slidably connected to the inner wall of the mounting groove 16.

[0029] In order to allow the stirring rod 5 to penetrate deep into the sampling barrel 6 and act precisely on the lower part of the slurry where it is easy to settle, the rotation of the stirring rod 5 can fully agitate the slurry, effectively break the settling balance of solid particles, prevent the slurry from stratifying in the sampling barrel 6, and ensure the uniformity of the slurry sample, in this embodiment, as a preferred technical solution of the present invention, the bottom end of the rotating shaft 4 extends into the interior of the sampling barrel 6, and the stirring rod 5 is located in the lower part of the inner cavity of the sampling barrel 6.

[0030] To ensure that the operating rod 9 can slide stably along the sampling barrel 6, thereby opening and closing the bottom cover 11 and displacing the sealing gasket 10; and to expel air from the sampling barrel 6 during sampling through the vent 14, thus preventing air from occupying the inner cavity space and causing the slurry to not fill the sampling barrel 6, and ensuring that the sampling amount is sufficient and meets the testing requirements, in this embodiment, as a preferred technical solution of the present invention, the operating rod 9 is slidably connected to the sampling barrel 6, and several sets of vent holes 14 are provided on both sides of the connection between the operating rod 9 and the sampling barrel 6.

[0031] In order to utilize the guiding effect of the arc-shaped end face during the reset process of the operating lever 9, so that the top end of the operating lever 9 can smoothly press the pin 18 and push the pin 18 to the left into the mounting plate 1, the pin 18 can be avoided without additional manual operation. After the insertion hole 15 is aligned with the pin 18, the pin 18 can be automatically inserted into the insertion hole 15 under the action of the spring 17 to complete the locking, thus improving the convenience of operation. In this embodiment, as a preferred technical solution of the present invention, the top end of the operating lever 9 is set to be arc-shaped, and its arc-shaped end face matches the lateral end of the pin 18.

[0032] In order to provide the operator with a convenient point of force through the handle 13, so as to easily push or pull the operating rod 9 to open and close the bottom cover 11; at the same time, the sealing ring 12 is used to enhance the sealing of the contact surface between the bottom cover 11 and the sampling bucket 6, to prevent the slurry from leaking or external impurities from entering during the sampling process, and to ensure the purity and integrity of the sampled sample, in this embodiment, as a preferred technical solution of the present invention, the top end of the operating rod 9 is fixed with a handle 13, and the contact surface between the bottom cover 11 and the sampling bucket 6 is fixed with a sealing ring 12.

[0033] In summary, with the help of the above-described technical solution of this utility model,

[0034] Working principle: When no sampling operation is performed, the device is in an initial sealed state. At this time, the operating rod 9 is locked to the mounting plate 1 by the pin 18—the pin 18 is inserted into the insertion hole 15 at the top of the operating rod 9 under the elastic thrust of the spring 17, restricting the axial movement of the operating rod 9. At the same time, the sealing gasket 10 of the operating rod 9 fits tightly against the top of the inner cavity of the sampling bucket 6, completely sealing the vent 14 at the connection between the sampling bucket 6 and the operating rod 9; the bottom cover 11 at the bottom of the operating rod 9 is sealed to the bottom port of the sampling bucket 6 by the sealing ring 12 of the mating surface, so that the inner cavity of the sampling bucket 6 forms a completely sealed space, preventing external impurities from entering or leakage before subsequent sampling.

[0035] Slurry Sampling Stage: When slurry sampling is required, the operator first inserts the sampling bucket 6 vertically downwards into the target sampling position of the slurry. Then, the operator pushes the push rod 21 in the sliding groove 19 at the top of the mounting plate 1 to the left. Since the push rod 21 is fixedly connected to the middle of the top of the pin 18, the push rod 21 drives the pin 18 to move to the left along the mounting groove 16 until the pin 18 is completely disengaged from the insertion hole 15 of the operating rod 9, releasing the lock on the operating rod 9. Then, the operator holds the handle 13 on the right side of the top of the operating rod 9 and pushes the operating rod 9 downwards. The operating rod 9 is fixedly connected to the slider 7 through the connecting block 8 and slides steadily downwards along the cylinder of the sleeve 3, simultaneously driving the sealing gasket 10 downwards from the top of the inner cavity of the sampling bucket 6 and the bottom cover 11 downwards away from the bottom port of the sampling bucket 6. At this time, the bottom of the sampling bucket 6 forms an open sampling channel. The slurry enters the inner cavity of the sampling bucket 6 from the bottom under the action of gravity and fluid pressure. At the same time, the vent 14 is released along with the sealing gasket 10. The sampling bucket 6 is lowered and opened, allowing air inside to escape through the vent 14, preventing air from occupying the inner cavity and preventing the slurry from filling completely, thus ensuring the sampling volume meets requirements. Once the sampling bucket 6 is filled with slurry, the handle 13 is pulled upwards to reset the operating rod 9. When the arc-shaped end face of the operating rod 9 contacts the lateral end of the pin 18, the lateral pressure generated by the arc-shaped surface pushes the pin 18 to the left into the mounting plate 1, and the pin 18 drives the limiting block 20 to compress the spring 17. When the operating rod 9 is reset to the point where the insertion hole 15 is coaxially aligned with the pin 18, the spring 17 releases its elastic potential energy, pushing the limiting block 20 and the pin 18 to the right, and the pin 18 is reinserted into the insertion hole 15 to lock it in place. At the same time, the sealing gasket 10 is once again pressed against the top of the inner cavity of the sampling bucket 6 to block the vent 14, and the bottom cover 11 seals the bottom of the sampling bucket 6 through the sealing ring 12, completing the sealing after sampling. The operator then removes the sampling bucket 6 from the slurry environment through the mounting plate 1.

[0036] If the slurry remains in the sampling bucket 6 for an extended period between sampling and sample discharge, solid particles are prone to settling and stratification. At this time, the motor 2 on top of the mounting plate 1 is activated. The output shaft of motor 2 drives the rotating shaft 4 to rotate coaxially. The stirring rod 5, fixed at the bottom of the rotating shaft 4, rotates with the shaft 4 in the lower part of the inner cavity of the sampling bucket 6, stirring the slurry and breaking the settling equilibrium of solid particles. This ensures the slurry remains uniform during sample discharge and testing, avoiding detection errors caused by settling. When testing the sampled slurry is required, push the push rod 21 to the left to disengage the pin 18 from the insertion hole 15. Then, push the operating rod 9 downwards using the handle 13, moving the bottom cover 11 away from the bottom of the sampling bucket 6. The slurry in the sampling bucket 6 flows out naturally from the bottom under gravity and enters the testing container, completing the sample discharge operation. The motor model mentioned above is 5IK120RGN-CF. This motor model is for reference only and should meet the operational requirements.
