Description

Technical Field

[0001] The present invention relates to the technical field of refinement testing, and more particularly to a device for testing the refinement of particle gradation in slurry pipeline transportation. Background Art

[0002] The refinement of particle gradation will have a significant impact on the transport characteristics of the slurry. When the particles in the slurry are refined, the viscosity of the slurry tends to increase. Accurately grasping the viscosity changes is crucial to determining the progress of particle gradation refinement. Usually, the end of refinement is marked by the end of viscosity increase.

[0003] However, existing technologies for testing the particle size distribution refinement during slurry pipeline transportation often use sampling tests to obtain viscosity data. However, the sampled slurry is difficult to return to the pipeline, resulting in slurry waste. Furthermore, the sampling and testing process is cumbersome, with numerous steps from sampling, transportation, to testing. This not only consumes time and manpower, but is also prone to deviations in test results due to external environmental interference. This makes it difficult to accurately and efficiently provide a reliable basis for judging the particle size distribution refinement process, thereby affecting the optimization and regulation of the slurry pipeline transportation system. In view of this, we propose a device for testing the particle size distribution refinement during slurry pipeline transportation. Summary of the Invention

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0019] like Figure 1-8 As shown, a slurry pipeline conveying particle grading refinement testing device includes a pipeline 1, the outer wall of the pipeline 1 is fixedly connected to a test cylinder 2, the inner wall of the pipeline 1 is fixedly connected to a pair of connecting pieces 3, the connecting pieces 3 are hollow plate structures, and the interior of the connecting pieces 3 is hollow, and the other side opposite to each other is provided with a plurality of connecting grooves 4 connected to the interior thereof, and the other side of the connecting pieces 3 is fixedly connected to a transfer pipe 5, the two ends of the transfer pipe 5 are respectively connected to the interior of the connecting piece 3 and the interior of the test cylinder 2, the bottom of the test cylinder 2 is fixedly connected to a storage cylinder 6 connected to the interior thereof, a viscosity sensor 7 is arranged inside the storage cylinder 6, a slurry extraction mechanism for layered extraction of slurry in the pipeline 1 is arranged inside the test cylinder 2, and a power mechanism for providing power to the slurry extraction mechanism is arranged at the bottom of the test cylinder 2.

[0020] Specifically, the pipeline 1 is used to transport the slurry, and the power mechanism is used to provide power for the slurry extraction mechanism, so that the slurry extraction mechanism extracts the slurry in the pipeline 1 through the transfer pipe 5, the connecting piece 3 and the connecting groove 4. At this time, it should be noted that since the connecting piece 3 and the transfer pipe 5 are located in the pipeline 1, the slurry in the pipeline 1 will be stored in the connecting piece 3 and the transfer pipe 5 through the connecting groove 4. In order to prevent this part of the slurry from mixing with the slurry in the pipeline 1 that is being tested immediately, thereby affecting the test effect of the slurry in the pipeline 1, the slurry extraction mechanism adopts layered extraction, which will draw the slurry stored in the connecting piece 3 and the transfer pipe 5 into the test cylinder 2 for layered storage, and then extract the slurry in the pipeline 1 through the connecting piece 3 and the transfer pipe 5, thereby further The accuracy of the test results is guaranteed in this step. Since the connecting piece 3 is a plate-shaped hollow structure, the slurry in the pipeline 1 can flow through the hollow part without affecting the conveying effect of the pipeline 1. Moreover, multiple connecting grooves 4 are used for slurry circulation at the same time, which allows the slurry extraction mechanism to extract slurry from different positions in the pipeline 1. These slurries will be mixed after entering the connecting piece 3, thereby further increasing the accuracy of the test results. The viscosity sensor 7 will perform a viscosity test on the slurry entering the test cylinder 2. After the test is completed, the slurry will be discharged from the test cylinder 2 by the slurry extraction mechanism, and it will be repeated in sequence to realize the particle grading refinement test of the slurry pipeline 1. The whole process is not only simple and convenient, but also an instant test of the slurry, and will not cause waste of slurry.

[0021] Furthermore, the slurry extraction mechanism includes an upper partition plate 8 and a lower partition plate 9 respectively arranged inside the test cylinder 2. The outer walls of the upper partition plate 8 and the lower partition plate 9 are both fitted with the inner wall of the test cylinder 2. The top of the upper partition plate 8 is provided with a plurality of upper plate grooves 10 passing through it. The inner wall of the upper plate groove 10 is fixedly connected with an upper sealing ring 11 made of rubber material. The top of the upper sealing ring 11 is fitted with an upper sealing piece 12 made of rubber material. The top of the upper sealing ring 11 is fixedly connected with a plurality of upper fixing columns 13 that pass through and fix the upper sealing piece 12. The top of the lower partition plate 9 is provided with a plurality of lower plate grooves 14 that pass through it. The inner wall of the upper plate groove 10 is fixedly connected with a lower sealing ring 15. The top of the lower sealing ring 15 is fitted with a lower sealing piece 16 made of rubber material. The top of the lower sealing ring 15 is fixedly connected with a plurality of lower fixing columns 17 that pass through and fix the lower sealing piece 16.

[0022] Specifically, the movement of the upper partition plate 8 and the lower partition plate 9 is controlled by a power mechanism. It should be noted that when the upper partition plate 8 is controlled to move upward by the power mechanism, a negative pressure is generated in the space between the upper partition plate 8 and the lower partition plate 9, so that the slurry stored in the connecting piece 3 is drawn into the space before the lower partition plate 9 moves. After the lower partition plate 9 moves upward, the slurry in the pipeline 1 is drawn into the space between the bottom of the test cylinder 2 and the lower partition plate 9, thereby realizing the layered extraction of the slurry. It should be noted that when the upper partition plate 8 moves downward, the slurry temporarily stored in the space between the upper partition plate 8 and the lower partition plate 9 is squeezed, so that the slurry enters the upper sealing ring 11 and pushes the upper sealing ring 11 made of rubber. One side of the upper sealing ring 11 It is fixed by the upper fixing column 13, so at this time the side of the upper sealing sheet 12 away from the upper fixing column 13 will be lifted, so that the slurry passes through the upper sealing sheet 12 into the upper plate groove 10, and then enters the space between the upper partition plate 8 and the top of the test cylinder 2. Similarly, the lower partition plate 9 moves downward, so that the slurry between the lower partition plate 9 and the bottom of the test cylinder 2 pushes the lower sealing sheet 16 from the lower sealing ring 15 into the space between the upper partition plate 8 and the lower partition plate 9, and then enters the space between the upper partition plate 8 and the top of the test cylinder 2. When the upper partition plate 8 moves up again, it will push the slurry again, so that the slurry returns to the pipeline 1 through another transfer pipe 5 and the connecting piece 3, and repeats in sequence to realize the layered extraction and instant testing of the slurry.

[0023] Furthermore, the power mechanism includes a bracket 18 fixedly connected to the bottom of the test cylinder 2, and a motor 19 is fixedly connected to the bottom of the bracket 18. The main shaft of the motor 19 passes through the bracket 18 and is fixedly connected to a threaded rod 20. The outer walls of the threaded rod 20 are respectively threadedly connected to an upper transmission ring 21 and a lower transmission ring 22. The bottom of the upper partition plate 8 is fixedly connected to a pair of upper linkage rods 23. The other ends of the upper linkage rods 23 pass through the lower partition plate 9 and the test cylinder 2 in sequence and are fixedly connected to the outer wall of the upper transmission ring 21. The bottom of the lower partition plate 9 is fixedly connected to a pair of lower linkage rods 24. The outer wall of the lower transmission ring 22 is provided with a connecting sleeve 25. The other end of the lower linkage rod 24 passes through the test cylinder 2 and is fixedly connected to the outer wall of the connecting sleeve 25. The outer wall of the lower transmission ring 22 is fixedly connected to an inner baffle 26. The inner wall of the connecting sleeve 25 is fixedly connected to an outer baffle 27 for blocking the inner baffle 26.

[0024] Specifically, the motor 19 drives the threaded rod 20 to rotate, and the upper transmission ring 21 is threadedly connected to it, and the upper linkage rod 23 fixedly connected to the bottom of the upper partition plate 8 axially limits the upper transmission ring 21. At this time, the upper transmission ring 21 will move and drive the upper partition plate 8 to move synchronously through the upper linkage rod 23. When the threaded rod 20 rotates, since the lower transmission ring 22 lacks the axial limiting effect, the transmission ring will rotate synchronously until the inner baffle 26 and the outer baffle 27 block each other. Similarly, the lower partition plate 9 The lower linkage rod 24 fixedly connected to the bottom axially limits the connecting sleeve 25, and the connecting sleeve 25 blocks the inner baffle 26 through the outer baffle 27 to achieve axial limitation of the lower transmission ring 22, so that the lower transmission ring 22 moves. When the lower transmission ring 22 moves and abuts against the inner end wall of the connecting sleeve 25, it can synchronously drive the connecting sleeve 25 to move synchronously, so that the connecting sleeve 25 drives the lower partition plate 9 to move through the lower linkage rod 24, thereby achieving the layered slurry extraction effect caused by the movement of the upper partition plate 8 and the lower partition plate 9.

[0025] Furthermore, a spring 28 is fixedly connected to the inner wall of the bottom of the storage tube 6, and the other end of the spring 28 is fixedly connected to an adjustment plate 29. The outer wall of the adjustment plate 29 fits the inner wall of the storage tube 6. The viscosity sensor 7 is fixedly connected to the bottom of the adjustment plate 29, and the detection probe of the viscosity sensor 7 passes through the adjustment plate 29 to its upper part.

[0026] Specifically, by setting the spring 28 to push the adjustment plate 29, the detection probe of the viscosity sensor 7 is located inside the test cylinder 2. When the lower partition plate 9 moves downward, it will push the viscosity sensor 7, so that the viscosity sensor 7 drives the adjustment plate 29 to squeeze the spring 28, causing the spring 28 to contract, and the adjustment plate 29 and the viscosity sensor 7 to move into the storage cylinder 6, thereby ensuring the fit between the bottom of the lower partition plate 9 and the inner wall of the bottom of the test cylinder 2, and ensuring the discharge effect of the slurry.

[0027] Furthermore, a push member 30 is fixedly connected to the top of the adjustment plate 29 . The push member 30 is a tubular structure, and the push member 30 covers the viscosity sensor 7 therein.

[0028] Specifically, by providing the push member 30 , the push member 30 contacts the bottom of the lower partition plate 9 , thereby preventing the viscosity sensor 7 from being squeezed by the lower partition plate 9 and damaged.

[0029] Furthermore, a slurry suction pipe 31 is fixedly connected to the bottom of the lower sealing ring 15 . The slurry suction pipe 31 is a tapered structure that is wide at the top and narrow at the bottom, and the slurry suction pipe 31 is in communication with the lower sealing ring 15 .

[0030] Specifically, the slurry suction pipe 31 is inserted into the storage tube 6 to extract the residual slurry in the storage tube 6, thereby further increasing the accuracy of subsequent slurry testing.

[0031] Furthermore, a counterweight ring 32 is fixedly connected to the bottom of the connecting sleeve 25 , and the threaded rod 20 is sleeved in the middle of the counterweight ring 32 .

[0032] Specifically, the connecting sleeve 25 is weighted by setting a counterweight ring 32, so that the counterweight ring 32 pulls the lower partition plate 9 through the connecting sleeve 25 and the lower linkage rod 24, thereby preventing the negative pressure generated in the space between the upper partition plate 8 and the lower partition plate 9 when the upper partition plate 8 moves, causing the lower partition plate to move up, thereby further ensuring the effect of layered extraction of the slurry.

[0033] Furthermore, the tube wall of the pushing member 30 is a hollow structure, and the hollow portion of the pushing member 30 connects the interior of the pushing member 30 with the interior of the testing tube 2 .

[0034] Specifically, the slurry enters between the push members 30 through the hollow portions of the push members 30 , thereby ensuring the contact effect between the viscosity sensor 7 and the slurry.

[0035] Working principle: This embodiment provides a slurry pipeline conveying particle grading refinement test device, the pipeline 1 is used to convey the slurry, and the power mechanism is used to provide power to the slurry pumping mechanism, so that the slurry pumping mechanism extracts the slurry in the pipeline 1 through the transfer pipe 5, the connecting piece 3 and the connecting groove 4. At this time, it should be noted that since the connecting piece 3 and the transfer pipe 5 are located in the pipeline 1, the slurry in the pipeline 1 will be stored in the connecting piece 3 and the transfer pipe 5 through the connecting groove 4. In order to prevent this part of the slurry from mixing with the slurry in the pipeline 1 that is being tested immediately, which will affect the test effect of the slurry in the pipeline 1, the slurry pumping mechanism adopts layered extraction, which will draw the slurry stored in the connecting piece 3 and the transfer pipe 5 into the test cylinder 2 for layered storage, and then extract it through the connecting piece 3 and the transfer pipe 5. The slurry in the pipeline 1 is taken to further ensure the accuracy of the test results. Since the connecting piece 3 is a plate-shaped hollow structure, the slurry in the pipeline 1 can flow from the hollow part without affecting the transportation effect of the pipeline 1. The multiple connecting grooves 4 are used for slurry circulation at the same time, which allows the slurry extraction mechanism to extract slurries from different positions in the pipeline 1. These slurries will be mixed after entering the connecting piece 3, thereby further increasing the accuracy of the test results. The viscosity sensor 7 will perform a viscosity test on the slurry entering the test cylinder 2. After the test is completed, the slurry will be discharged from the test cylinder 2 by the slurry extraction mechanism, and it will be repeated in sequence to realize the particle grading refinement test of the slurry pipeline 1. The whole process is not only simple and convenient, but also an instant test of the slurry, and will not cause waste of slurry.
