Description

Technical Field

[0001] This invention relates to the field of testing technology for phosphate rock backfill cementitious materials, specifically a sampling device for testing phosphate rock backfill cementitious materials. Background Technology

[0002] In today's phosphate mining industry, phosphate mining companies generally also produce products such as phosphoric acid and yellow phosphorus. However, producing 1 ton of phosphoric acid yields 3-5 tons of phosphogypsum. Phosphogypsum contains impurities such as phosphoric acid, phosphorus, and phosphorus, and long-term storage can easily cause pollution of surface / groundwater bodies. Meanwhile, in the self-flowing tailings backfilling cementitious system, the mass concentration of the backfill slurry is usually ≤70%. This concentration of backfill slurry contains a relatively high amount of water, requiring sampling and testing during the backfilling process to ensure that the quality of the backfill slurry meets the requirements.

[0003] Currently, when the sampling device used for testing phosphate rock backfill cementitious materials is inserted into the backfill cement material to the required sampling depth, the backfill cement material in the upper area will seep into the sampling device due to inertia, affecting the sampling results at the required depth.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its deficiencies, and proposed a sampling device for testing phosphate rock filling cementitious materials. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a sampling device for testing phosphate rock backfill cementitious materials, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sampling device for detecting phosphate rock backfill cementitious materials, comprising a collection disc and a drive gear. A vacuum pump is disposed in the middle of the collection disc, and a collection pipe is installed at the input end of the vacuum pump. A negative pressure pipe is connected inside the collection pipe, and a sampling pipe is disposed at the end of the negative pressure pipe. An auxiliary component for sampling, sealing, and interference prevention is installed inside the sampling pipe. The auxiliary component includes a built-in plug, a connecting rod, and a top scraper. A connecting rod is disposed on the top outer surface of the built-in plug, and a top scraper is installed on the top of the connecting rod. A connecting component for auxiliary position adjustment is disposed on one side of the bottom of the built-in plug. The connecting component includes a connecting sleeve and a transition rod. A transition rod is disposed on the outer surface of the connecting sleeve, and a threaded rod is installed internally on the transition rod. A driven wheel is disposed on the top of the threaded rod. The drive gear meshes with the outer surface of the driven wheel. A servo motor is disposed in the middle of the drive gear via a drive shaft. A central base is disposed at the bottom of the vacuum pump.

[0007] Furthermore, the servo motor is provided with a connecting frame on its exterior, and a ventilation opening is provided in a ring at the bottom of the connecting frame.

[0008] Furthermore, a connecting pipe is provided inside one of the ventilation openings, and a manifold is installed at the end of the connecting pipe.

[0009] Furthermore, the negative pressure tube and the sampling tube are provided in three sets, and the negative pressure tube is equipped with a valve inside.

[0010] Furthermore, an auxiliary disk is provided at the bottom of the driven wheel, and a threaded rod is rotatably installed inside the auxiliary disk.

[0011] Furthermore, the threaded rod is provided with a connecting component for assisting position adjustment and cleaning the outer surface of the sampling tube. The connecting component also includes a collection plate and an external sleeve. The upper outer surface of the connecting sleeve is provided with a collection plate, and the end of the collection plate is equipped with an external sleeve.

[0012] Furthermore, the external sleeve is slidably disposed outside the sampling tube, and the height between the external sleeves is higher than the height formed by the internal plug, connecting rod and top scraper.

[0013] Furthermore, the inside of the collection plate is provided with an internal groove in a ring shape, and a connecting frame is provided inside the internal groove.

[0014] Furthermore, a connecting seat is slidably installed inside the connecting frame, and an adjusting screw is installed at one end of the connecting seat.

[0015] Furthermore, the adjusting screw is threadedly installed in the middle of one end of the connecting frame, a sampling tube is engaged in the middle of the connecting seat, and a handle is provided on one side of the outer surface of the collecting plate.

[0016] This invention provides a sampling device for testing cementitious materials used in phosphate rock backfilling, which has the following advantages:

[0017] 1. The sampling device for testing phosphate rock backfill gelling material can move the connecting sleeve plate on the outer surface of the threaded rod up and down by rotating the threaded rod clockwise or counterclockwise. As the connecting sleeve plate moves down along the threaded rod, the built-in plug at one end of the adapter rod will separate from the inside of the sampling tube. This prevents the backfill gel from seeping into the sampling tube before reaching the required depth due to inertia when the sampling tube is inserted into the backfill gel material, thus affecting the accuracy of the sample testing at the required depth and avoiding contamination when sampling the backfill gel at the required depth.

[0018] 2. The sampling device for testing phosphate rock backfill cementitious materials uses a reverse rotation of the threaded rod to move the connecting sleeve plate on the outer surface of the threaded rod upward. This causes the built-in plug connected to the connecting sleeve plate to seal the sampling port of the sampling tube again, preventing the sample from spilling. When sampling, rotating the threaded rod causes the connecting sleeve plate on the outer surface of the threaded rod to move downward. This causes the built-in plug, connecting rod, and top scraper to move downward against the inner surface of the sampling tube. The top scraper assists in the discharge of the sample from inside the sampling tube during the downward movement of the sampling tube and also cleans the inner surface of the sampling tube, preventing the sample from adhering to the inner surface of the sampling tube.

[0019] 3. The sampling device for testing the phosphate rock filling gel material, when sampling, rotates the threaded rod clockwise or counterclockwise, causing the connecting sleeve plate on the outer surface of the threaded rod to move down or up. This causes the collection plate and the outer sleeve plate connected to the connecting sleeve plate to move synchronously, and the outer sleeve plate to move up or down synchronously against the outer surface of the sampling tube. This allows the outer surface of the sampling tube to be cleaned simultaneously after the sampling tube is removed from the filling gel material (i.e., when sampling the sample from the sampling tube), thus avoiding excessive adhesion of filling gel material to the outer surface of the sampling tube.

[0027] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0028] like Figures 1-6As shown, the present invention provides a technical solution: a sampling device for detecting phosphate rock backfill cementitious materials, comprising a collection plate 1, a central seat 2, a vacuum pump 3, a valve 4, a negative pressure pipe 5, a collection pipe 6, a connecting frame 7, an auxiliary plate 8, a sampling pipe 9, a connecting frame 10, a servo motor 11, a vent 12, a connecting pipe 13, a driven wheel 14, an internal groove 15, an adjusting screw 16, a connecting seat 17, an auxiliary component 18, an internal plug 1801, a connecting rod 1802, a top scraper 1803, a threaded rod 19, a connecting component 20, a connecting sleeve 2001, a transition connecting rod 2002, a collection plate 2003, an external sleeve 2004, a drive gear 21, and a handle 22. The vacuum pump 3 is located in the center of the collection plate 1, and the input end of the vacuum pump 3 is equipped with... A manifold 6 is internally connected to a negative pressure pipe 5. Three sets of negative pressure pipes 5 and sampling pipes 9 are provided. A valve 4 is installed inside the negative pressure pipe 5, and a sampling pipe 9 is installed at the end of the negative pressure pipe 5. An auxiliary component 18 for sampling, sealing, and interference prevention is installed inside the sampling pipe 9. The auxiliary component 18 includes a built-in plug 1801, a connecting rod 1802, and a top scraper 1803. The connecting rod 1802 is provided on the top outer surface of the built-in plug 1801, and a top scraper 1803 is installed on the top of the connecting rod 1802. A connecting component 20 for auxiliary position adjustment is provided on one side of the bottom of the built-in plug 1801. The connecting component 20 includes a connecting sleeve 2001 and an adapter rod 2002. The outer surface of the connecting sleeve 2001 is provided with an adapter rod. The connecting rod 2002 has a threaded rod 19 internally threaded on it, and a driven wheel 14 is provided at the top of the threaded rod 19. The driving gear 21 is meshed with the outer surface of the driven wheel 14. A servo motor 11 is provided in the middle of the driving gear 21 via a drive shaft. A central seat 2 is provided at the bottom of the vacuum pump 3. After the sampling tube 9 is placed in the required filling gel material, the design of the servo motor 11 and the drive shaft can drive the driving gear 21 to rotate. The rotation of the driving gear 21 can drive the driven wheel 14 to rotate. The rotation of the driven wheel 14 will drive the threaded rod 19 connected to the driven wheel 14 to rotate. The clockwise or counterclockwise rotation of the threaded rod 19 can drive the connecting sleeve plate on the outer surface of the threaded rod 19. The 2001 moves up or down, so that when the connecting sleeve 2001 moves down along the threaded rod 19, the built-in plug 1801 at one end of the adapter rod 2002 will separate from the inside of the sampling tube 9. This prevents the filling gel at other depths from seeping into the sampling tube 9 before reaching the required depth due to inertia when the sampling tube 9 is inserted into the filling gel material, affecting the accuracy of sample testing at the required depth and avoiding contamination when sampling the filling gel at the required depth. During sampling, by opening the valve 4 at the negative pressure tube 5, the vacuum pump 3 is used to put the negative pressure tube 5 connected to the manifold 6 and the sampling tube 9 into a negative pressure state. The negative pressure generated by the sampling tube 9 can perform negative pressure extraction of the filling gel material, thereby realizing the sampling of the filling gel material.Furthermore, the valve 4 and the negative pressure pipe 5 are designed in a one-to-one correspondence, facilitating the selective use of sampling tubes 9 for different ranges within the required sampling range. After sampling is completed, by rotating the threaded rod 19 in the reverse direction, the connecting sleeve 2001 on the outer surface of the threaded rod 19 moves upward, thereby causing the built-in plug 1801 connected to the connecting sleeve 2001 to seal the sampling port of the sampling tube 9 again, preventing the extracted sample from spilling. When sampling is performed, by rotating the threaded rod 19, the connecting sleeve 2001 on the outer surface of the threaded rod 19 moves downward, causing the built-in plug 1801, connecting rod 1802, and top scraper 1803 to move downward against the inner surface of the sampling tube 9. During the downward movement of the sampling tube 9, the top scraper 1803 assists in the unloading of the sample extracted inside the sampling tube 9 and also cleans the inner surface of the sampling tube 9, preventing the sample from adhering to the inner surface of the sampling tube 9.

[0029] like Figure 1 and Figure 3 As shown, a connecting frame 10 is provided on the outside of the servo motor 11, and a vent 12 is provided in a ring at the bottom of the connecting frame 10. A connecting pipe 13 is provided inside a set of vents 12, and a manifold 6 is installed at the end of the connecting pipe 13. When the vacuum pump 3 is activated, the connecting pipe 13 connected to the manifold 6 is in an adsorption state, which can adsorb the heat generated by the servo motor 11 when the connecting frame 10 is working, so that the air outside the connecting frame 10 can circulate quickly through the vent 12, thereby increasing the air flow rate inside the connecting frame 10 and dissipating heat from the servo motor 11.

[0030] like Figure 2 , Figure 5 and Figure 6An auxiliary disc 8 is provided at the bottom of the driven wheel 14, and a threaded rod 19 is rotatably mounted inside the auxiliary disc 8. A connecting assembly 20 for assisting position adjustment and cleaning the outer surface of the sampling tube 9 is provided outside the threaded rod 19. The connecting assembly 20 also includes a collection plate 2003 and an outer sleeve 2004. The collection plate 2003 is provided on the upper outer surface of the connecting sleeve 2001, and the outer sleeve 2004 is installed at the end of the collection plate 2003. The outer sleeve 2004 is slidably disposed outside the sampling tube 9, and the height between the outer sleeve 2004 and the connecting rod 1 is higher than that of the built-in plug 1801 and the connecting rod 1. The height formed between 802 and the top scraper 1803 allows the connecting sleeve 2001 on the outer surface of the threaded rod 19 to move down or up during sampling by rotating the threaded rod 19 clockwise or counterclockwise. This causes the collection plate 2003 and the outer sleeve 2004 connected to the connecting sleeve 2001 to move synchronously. The outer sleeve 2004 will also move up or down synchronously against the outer surface of the sampling tube 9. This allows the outer surface of the sampling tube 9 to be cleaned simultaneously after it is removed from the filling gel material and the sample is taken from the sampling tube 9, thus preventing excessive filling gel material from adhering to the outer surface of the sampling tube 9.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, the collection tray 1 has an internal groove 15 in a ring shape, and a connecting frame 7 is set inside the internal groove 15. A connecting seat 17 is slidably installed inside the connecting frame 7, and an adjusting screw 16 is installed at one end of the connecting seat 17. The adjusting screw 16 is threaded into the middle of one end of the connecting frame 7. A sampling tube 9 is engaged in the middle of the connecting seat 17. A handle 22 is set on one side of the outer surface of the collection tray 1, which can be used to operate the entire sampling device. Then, the sampling tube 9 inside the connecting seat 17 can be pulled upward according to the sampling depth. After the position is adjusted, it can be fixed with screws. In this way, the depth of the three sets of sampling tubes 9 relative to the filling gel material can be adjusted.

[0032] In summary, as Figures 1-6As shown, the sampling device for testing phosphate rock filling gelling materials can be operated by holding the handle 22. The sampling tube 9, located inside the connecting seat 17, can be pulled upwards according to the sampling depth. After adjustment, it can be fixed with screws. This allows adjustment of the depth of the three sets of sampling tubes 9 relative to the filling gel material. Once the sampling tube 9 is in the required filling gel material, the servo motor 11 and drive shaft drive the drive gear 21 to rotate. The rotation of the drive gear 21 drives the driven wheel 14, which in turn drives the threaded rod 19 connected to it to rotate. The threaded rod 19 can rotate clockwise or counterclockwise. The connecting sleeve 2001 on the outer surface of the threaded rod 19 can move up or down. When the connecting sleeve 2001 moves down along the threaded rod 19, the built-in plug 1801 at one end of the adapter rod 2002 will separate from the inside of the sampling tube 9. This prevents the filling gel from seeping into the sampling tube 9 before reaching the required depth due to inertia, thus affecting the accuracy of sample testing at the required depth and preventing contamination during sampling of the filling gel at the required depth. During sampling, by opening the valve 4 at the negative pressure pipe 5, the vacuum pump 3 ensures that the negative pressure pipe 5 connected to the manifold 6 and the sampling tube 9 are under negative pressure. The negative pressure generated by the sampling tube 9 can effectively penetrate the filling gel material. Negative pressure extraction is used to sample the filling gel material. Valve 4 and negative pressure pipe 5 are designed in a one-to-one correspondence, facilitating selective use of sampling tubes 9 for different ranges. After sampling, rotating the threaded rod 19 in the reverse direction causes the connecting sleeve 2001 on the outer surface of the threaded rod 19 to move upwards. This causes the built-in plug 1801 connected to the connecting sleeve 2001 to re-seal the sampling port of the sampling tube 9, preventing sample spillage. During sampling, rotating the threaded rod 19 causes the connecting sleeve 2001 on the outer surface of the threaded rod 19 to move downwards. This causes the built-in plug 1801, connecting rod 1802, and top scraper 1803 to conform to the inner surface of the sampling tube 9 and move downwards. The top scraper 1803 then conforms to the sampling tube 9. During the downward movement, the sample is fed into the sampling tube 9 and the inner surface of the sampling tube 9 is cleaned to prevent the sample from adhering to the inner surface of the sampling tube 9. Then, when sampling is performed, the connecting sleeve 2001 on the outer surface of the threaded rod 19 moves down or up by rotating the threaded rod 19 clockwise or counterclockwise. As a result, the collection plate 2003 and the outer sleeve 2004 connected to the connecting sleeve 2001 move synchronously, and the outer sleeve 2004 will fit against the outer surface of the sampling tube 9 and move up or down synchronously. Thus, the outer surface of the sampling tube 9 can be cleaned simultaneously when the sample is taken from the sampling tube 9 after it is removed from the filling gel material, so as to prevent a lot of filling gel material from adhering to the outer surface of the sampling tube 9.
