Abstract
Description
Technical Field
[0001] This invention relates to the field of attapulgite viscosity testing technology, specifically an attapulgite viscosity measuring device. Background Technology
[0002] Attapulgite is a hydrous magnesium-aluminate silicate clay mineral with a special layered chain crystal structure. Its aqueous suspension has unique rheological properties and thickening properties, and it is widely used in building materials, chemical industry, pharmaceutical industry and other fields. Viscosity is the core indicator for evaluating the quality, dispersion performance and application effect of attapulgite. Its accurate measurement is crucial for production quality control and product development.
[0003] For example, Chinese Patent Publication No. CN223808303U discloses an attapulgite clay viscosity measuring device. Its main structure includes: a fixed base, a side wall fixing block, a vertical rod, a sliding lifting block, a viscosity testing device and probe, a base with a circular groove, and a testing cup.
[0004] In this scheme, a circular groove is opened on the fixed base, and the sample cup is placed in the circular groove. The distance of the rotor probe on the viscometer into the sample cup is controlled by manually adjusting the lifting block. This makes it impossible to continuously measure multiple attapulgite soil samples. In addition, there are errors in manual adjustment, and it cannot be guaranteed that the rotor probe is inserted into the sample cup at the same distance when testing multiple samples. This may lead to errors in the measurement results. Furthermore, when cleaning the rotor probe after testing, the height of the viscometer still needs to be manually adjusted repeatedly.

Detailed Implementation
[0032] Please see Figure 1-3 In this embodiment of the invention, an attapulgite viscosity measuring device includes a base 1 and a turntable 2. A drive mechanism for driving the turntable 2 to rotate is provided at the lower middle part of the base 1. A symmetrical receiving cavity 4 is opened at the upper end of the turntable 2. A mounting plate is fixedly connected to the middle part of one side of the upper end of the base 1. A viscometer body 3 is fixedly connected to the upper side of the mounting plate. The viscometer body 3 is a commonly used technical means in the prior art. A rotor probe 10 is drivenly connected to the middle part of its lower end. An adjustment component is provided on the side of the upper end of the base 1 near the viscometer body 3. When the drive mechanism rotates counterclockwise, the adjustment mechanism moves away from the position of the viscometer body 3, and the turntable 2 rotates clockwise. When the drive mechanism rotates clockwise, the adjustment mechanism moves closer to the position of the viscometer body 3, and the turntable 2 remains stationary.
[0033] When measuring the viscosity of a new material like attapulgite, the viscosity of an aqueous suspension of attapulgite is usually tested. Typically, a viscometer body 3 is used to measure the viscosity. The rotor probe 10 is placed in the aqueous suspension of attapulgite, hereinafter referred to as attapulgite slurry. The rotor probe 10 is driven to rotate in the slurry by the viscometer body 3, thereby measuring the viscosity of the slurry.
[0034] The inner cavity of the receiving cavity 4 contains sample cups, and the inner cavities of the sample cups contain attapulgite slurry and cleaning fluid, respectively. The viscosity of the attapulgite slurry in the inner cavity of the sample cup can be measured through the viscometer body 3. The sample cups containing cleaning fluid and sample cups containing attapulgite slurry are placed alternately, that is, between two adjacent sample cups containing attapulgite slurry, there is a sample cup containing cleaning fluid. This facilitates timely cleaning of the viscometer body 3 after the viscosity measurement of the attapulgite slurry, which in turn facilitates continuous measurement of attapulgite slurry in different sample cups. During continuous measurement, the cleaning fluid can prevent the slurry residue on the viscometer body 3 after the previous measurement from affecting the measurement results of the subsequent slurry.
[0035] Please see Figure 2 , Figure 7 and Figure 11-12 The base 1 has a mounting groove 22 at the lower center and a circular groove 19 at the upper center. The circular groove 19 has an installation groove 21 at the upper center. A motor mounting base is fixedly connected to the inner cavity of the mounting groove 22. A servo motor 36 is drivenly connected to the middle of the motor mounting base. A drive rod 37 is fixedly connected to the output end of the servo motor 36. A driven rod 38 is rotatably connected to the upper part of the other end of the drive rod 37. A transmission rod 39 is rotatably connected to the end of the driven rod 38 away from the drive rod 37. A moving groove 40 is provided at the bottom of the inner cavity of the mounting groove 21. A drive plate 42 is fixedly connected to the top of the transmission rod 39. The outer wall of the transmission rod 39 is slidably connected to the inner cavity of the moving groove 40. A rotating rod 20 is rotatably connected to the bottom of the inner cavity of the mounting groove 21. A drive gear 41 is fixedly connected to the lower outer wall of the rotating rod 20. A rack 43 is fixedly connected to the middle of the side of the drive plate 42 near the rotating rod 20.
[0036] During the rotation of the servo motor 36, the drive rod 37 will rotate synchronously. The top of the mounting plate is lower than the lower end face of the drive rod 37. The drive rod 37 will drive the driven rod 38 to move back and forth during the deflection process, which in turn drives the transmission rod 39 to move horizontally back and forth in the inner cavity of the moving groove 40, thereby driving the drive plate 42 and the rack 43 to move horizontally back and forth. Since the length of the drive plate 42 is greater than the length of the rack 43, the drive plate 42 will only drive the rotating rod 20 to rotate 180° when the rack 43 contacts the drive gear 41 during the horizontal back and forth movement. Therefore, after rotating 180° counterclockwise, the rotating rod 20 will remain stationary for a certain period of time, and then rotate 180° clockwise again and remain stationary again.
[0037] Please see Figure 2-7A groove 23 is provided at the bottom of the inner cavity of the circular groove 19 near the viscometer body 3. A threaded sleeve 17 is rotatably connected to the inner cavity of the groove 23. A threaded rod 18 is threadedly connected to the middle of the upper end of the threaded sleeve 17. A bearing plate 9 is fixedly connected to the top of the threaded rod 18. A symmetrical horizontal plate 5 is fixedly connected to the outer wall of the bearing plate 9. A through groove 6 is provided on the inner side wall of the receiving cavity 4, which slides with the horizontal plate 5. A positioning block 7 is slidably connected to the middle of the upper end of the horizontal plate 5. Positioning rods 8 are fixedly connected to the middle of both sides of the positioning block 7. A symmetrical guide groove 11 is provided on the inner side wall of the through groove 6, which slides with the positioning rods 8.
[0038] After the sample cup is placed in the inner cavity of the receiving cavity 4, the position of the receiving cavity 4 closest to the viscometer body 3 coincides with the position of the support plate 9. Therefore, the position of the through groove 6 in the inner cavity of the receiving cavity 4 also coincides with the position of the horizontal plate 5. At this time, the threaded rod 18 drives the circular groove 19 to move upward, which will push the sample cup to move upward synchronously. At the same time, the sliding cooperation between the guide groove 11 and the positioning rod 8 drives the positioning block 7 to center and clamp the sample cup, thereby avoiding the sample cup from shaking when measuring attapulgite slurry or cleaning the rotor probe 10, which would affect the measurement results and prevent inadequate cleaning.
[0039] Please see Figure 4 The guide groove 11 consists of two vertical grooves and one inclined groove connected end to end. The inclined groove is located in the lower part of the inner cavity of the through groove 6, and the length of the vertical groove connected to the upper end of the inclined groove is greater than the length of the vertical groove connected to the lower end of the inclined groove. The positioning block 7 and the horizontal plate 5 are elastically connected by a spring to ensure that after the positioning rod 8 is separated from the guide groove 11, the position of the positioning rod 8 corresponds to the vertical groove located on the lower side. This ensures that after the turntable 2 rotates clockwise, the positioning rod 8 can accurately enter the guide groove 11 in different inner cavities of the through groove 6, which facilitates continuous measurement of attapulgite slurry of different qualities. After the turntable 2 rotates, it will remain stationary for a certain period of time, which also makes it easy to remove the measured attapulgite slurry along with the sample cup from the inner cavity of the receiving cavity 4, so as to replace it with a new sample cup containing attapulgite slurry.
[0040] Please see Figure 2 and Figure 5-7An incomplete gear 14 is vertically slidably connected to the upper end of the transmission rod 20, and a transmission gear 16 is fixedly connected to the outer wall of the threaded sleeve 17. The transmission gear 16 meshes with the incomplete gear 14. During a 180° counterclockwise rotation, the transmission gear 16 drives the threaded sleeve 17 to rotate, which in turn drives the threaded rod 18 and the bearing plate 9 to move vertically upward, pushing the sample cup to move upward synchronously within the cavity of the receiving chamber 4. This positions the rotor probe 10 in the attapulgite slurry or cleaning liquid, thereby completing the viscosity measurement of the attapulgite slurry or the measurement of the rotor probe 10. The contact time between the incomplete gear 14 and the transmission gear 16 is fixed, so the upward and downward distances of the sample cup are fixed. During the measurement or cleaning process, there is no need to repeatedly adjust the height of the viscometer body 3. After the viscosity measurement or cleaning is completed, the sample cup will automatically move down and rotate 60° clockwise with the turntable 2, which can quickly complete the replacement of the sample cup position. This ensures that the rotor probe 10 can be cleaned in time after completing a viscosity measurement of the attapulgite slurry, and also facilitates continuous measurement of attapulgite slurry of different qualities.
[0041] Please see Figure 5-7 A driven gear 15 is rotatably connected to one side of the inner cavity of the circular groove 19. The vertical height of the driven gear 15 is less than the vertical height of the incomplete gear 14, and the height of the incomplete gear 14 is less than the vertical height of the transmission gear 16. The upper end face of the transmission gear 16 is lower than the lower end face of the driven gear 15. A connecting ring 12 is fixedly connected to the lower end of the turntable 2, and a gear ring 13 is fixedly connected to the lower end of the connecting ring 12. The gear ring 13 meshes with the driven gear 15, and the height of the gear ring 13 is the same as the height of the driven gear 15. That is, the gear ring 13 and the transmission gear 16 are in a separated state and are not affected by the motion state of the other. During the process of the complete gear 14 rotating counterclockwise 180°, the transmission gear 16 will contact the incomplete gear 14 before the driven gear 15. Then, during the process of the transmission gear 16 driving the threaded sleeve 17 to rotate, that is, when the threaded rod 18 moves vertically downward, the turntable 2 remains stationary. An adjusting ring 24 is fixedly connected to the middle of the inner cavity of the mounting groove 21. The inner cavity side wall of the adjusting ring 24 is provided with an adjusting component for adjusting the position of the incomplete gear 14, ensuring that the incomplete gear 14 only contacts the driven gear 15 once and contacts the transmission gear 16 twice during the process of reciprocating rotation 180°.
[0042] Please see Figure 7-8The adjustment assembly includes two slots 28 of different heights, located on opposite sides of the inner cavity of the adjustment ring 24. A short rod 25 and a long rod 26 are fixedly connected to the lower ends of the incomplete gear 14, respectively. The lower end face of the short rod 25 is higher than that of the long rod 26. Movable rods 27 are elastically connected to the lower sides of both the short rod 25 and the long rod 26 away from the rotating rod 20. The two movable rods 27 are slidably connected to the two slots 28 on the sides away from the rotating rod 20. The only difference between the two movable rods 27 and the two slots 28 is their height and position. Slots 30 and 31 are respectively opened on the lower sides of both ends of slot 28. A slot 29 is opened between the lower ends of slots 30 and 31. Slots 28 and 29 have the same length. The movable rods 27 slide in contact with the inner cavities of slots 29, 30, and 31.
[0043] As the incomplete gear 14 drives the short rod 25 and the long rod 26 to rotate 180° back and forth, the movable rod 27 will move from the connection between the first slot 28 and the third slot 30 along the inner cavity of the first slot 28 to the connection between the first slot 28 and the fourth slot 31. The end of the inner cavity of the first slot 28 near the fourth slot 31 is fixedly connected to the inclined block 32. The inclined block 32 has an inclined surface on the side away from the fourth slot 31. As the movable rod 27 moves in the inner cavity of the first slot 28, it will come into contact with the inclined surface and then retract towards the direction of the rotating rod 20 into the inner cavity of the short rod 25 or the long rod 26. After the movable rod 27 passes the inclined block 32, it will pop out again. At this time, the other side of the inclined block 32 will block the movable rod 27 to prevent the movable rod 27 from returning to the inner cavity of the first slot 28.
[0044] Please see Figure 9 Furthermore, a magnet is embedded in the middle of the inner cavity of the movable rod 27, and a magnet 33 is fixedly connected to the top of the inner cavity of the fourth slot 31. The magnet 33 and the magnet embedded in the inner cavity of the movable rod 27 are of the same name. Therefore, after the movable rod 27 is located in the inner cavity of the fourth slot 31, under the gravity of the incomplete gear 14, the short rod 25 and the long rod 26, and the repulsive force of the magnet, the movable rod 27 will move down along the fourth slot 31 to the connection between the second slot 29 and the fourth slot 31. Since the length of the rack 43 is less than the length of the drive plate 42, after the rotating rod 20 drives the incomplete gear 14 and the movable rod 27 to rotate 180° once, it will remain still for a certain period of time. At this time, the movable rod 27 has enough time to move down along the inner cavity of the fourth slot 31, and during the process of the incomplete gear 14 rotating 180°, it moves along the inner cavity of the second slot 29.
[0045] Please see Figure 8-10An inclined block 32 is fixedly connected to one end of the inner cavity of slot 29 near slot 30. An inclined surface is provided on the side of the inclined block 32 away from slot 30. The inclined block 32 in the inner cavity of slot 29 has the same specifications and function as the inclined block 32 in the inner cavity of slot 1. A sliding groove 35 is provided in the middle of the inner cavity of slot 30 away from the inclined block 32. A guide plate 34 is slidably connected to the inner cavity of the sliding groove 35. The side wall of the guide plate 34 is elastically connected to the side wall of the inner cavity of the sliding groove 35 by a spring. Therefore, when the guide plate 34 is not subjected to external force, the bottom of the guide plate 34 is in contact with the bottom of the inner cavity of slot 29, and the top of the guide plate 34 is in contact with the bottom of the inner cavity of slot 1. The length of the bottom of the guide plate 34 is greater than the length of its top. The length of the top of the guide plate 34 is the same as the width of slot 30.
[0046] The guide plate 34 is closer to the rotating rod 20 than the inclined block 32. Therefore, as the movable rod 27 moves toward the inner cavity of the third groove 30, the outer wall of the movable rod 27 will contact the guide plate 34 first. Since the movable rod 27 is restricted in the vertical direction by the second groove 29, the movable rod 27 will push the guide plate 34 to retract into the inner cavity of the slide groove 35. When the movable rod 27 retracts after contacting the inclined block 32, the movable rod 27 will still push the guide plate 34 to move. After the movable rod 27 is in the inner cavity of the third groove 30, the inclined block 32 blocks the movable rod 27. The rebound of the guide plate 34 will push the movable rod 27 to move upward and return to the connection between the first groove 28 and the third groove 30.
[0047] Therefore, after rotating 180° counterclockwise, the incomplete gear 14 will stop rotating and move downwards before rotating 180° clockwise again. After moving downwards, the incomplete gear 14 will separate from the driven gear 15. During the clockwise rotation and reset process, the incomplete gear 14 will not drive the gear ring 13 and the turntable 2 to rotate. That is, during the 180° reciprocating rotation of the incomplete gear 14, the gear ring 13 and the turntable 2 will only rotate 60° clockwise. The clockwise rotation of the incomplete gear 14 will cause it to make secondary contact with the transmission gear 16, thereby driving the thread. As rod 18 and bearing plate 9 move upward, after measuring the attapulgite slurry, the turntable 2 is driven to rotate 60° clockwise to change the position of the cleaning liquid and the attapulgite slurry. The sample cup containing the cleaning liquid is then lifted to clean the rotor probe 10. After cleaning, the incomplete gear 14 is driven by servo motor 36 to rotate 180° back and forth to remove the sample cup containing the cleaning liquid. The subsequent sample cup containing the attapulgite slurry is then moved to below the rotor probe 10 and lifted, thereby achieving continuous measurement of the attapulgite slurry.
