DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figures 1 to 4 As shown, a phosphate rock flotation pulp sedimentation test device includes a first frame 1 for supporting a measuring cylinder, and a second frame 2 for sealing the upper end of the measuring cylinder is provided above the first frame 1.

[0027] Specifically, the first frame 1 includes an elongated base 3, which is shaped like a slot with an open top. First connecting arms 4, extending upward, are integrally formed at each of the left and right ends of the base 3 along its length. The base 3 is provided with multiple circular positioning slots 5 that match graduated cylinders, allowing multiple graduated cylinders to be placed within the base 3 at once. These positioning slots 5 are evenly spaced along the length of the base 3, allowing the lower ends of graduated cylinders to be placed within the positioning slots 5. These positioning slots 5 provide a positional limit for the graduated cylinders, preventing them from shifting and colliding during shaking.

[0028] The second frame 2 includes a top support 6, which is shaped like a slot with an open bottom. Downward-extending second connecting arms 7 are integrally formed at the left and right ends of the bottom support 3 along its length. Multiple graduated cylinders are placed within the bottom support 3, and then the top support 6 is snapped onto their upper ends. This seals the tops of the cylinders simultaneously, allowing the cylinders to be shaken simultaneously to conduct slurry sedimentation tests. Furthermore, a resilient plastic pad 19 is provided within the top support 6 to enhance the seal around the cylinder openings.

[0029] The second connecting arm 7 is attached to the outer side of the first connecting arm 4 on the corresponding side. Figure 2 and Figure 3 As shown, a transversely extending fixed shaft 8 is fixedly installed on the outer side of the first connecting arm 4, and one end of the fixed shaft 8 is embedded in or threadedly connected to the first connecting arm 4; a transversely extending strip hole 9 is provided on the second connecting arm 7, and the length direction of the strip hole 9 extends vertically along the length direction of the second connecting arm 7. The fixed shaft 8 passes through the corresponding strip hole 9 and can slide along the length direction of the strip hole 9, so that the second frame 2 can move up and down within a certain range. Specifically, after placing the measuring cylinder into the bottom support 3, the second frame 2 is moved downward, and the upper ends of multiple measuring cylinders are simultaneously closed by the top support 6. At the same time, the first frame 1 and the second frame 2 cooperate with each other to clamp the multiple measuring cylinders. Then, the first frame 1 and the second frame 2 can be shaken to drive the multiple measuring cylinders to shake; or after the slurry sedimentation test is completed, the second frame 2 is moved upward to separate the top support 6 from the measuring cylinder so that the measuring cylinder can be taken out from between the first frame 1 and the second frame 2.

[0030] A hanging plate 10 is rotatably mounted on the first frame 1. In this embodiment, the hanging plate 10 is rotatably mounted on a fixed shaft 8 located outside the second connecting arm 7. The fixed shaft 8 has an integrally formed stopper on the end away from the first connecting arm 4 to prevent the hanging plate 10 from falling off. A laterally extending hanging rod 11 is integrally formed or welded to the outside of the second connecting arm 7 below the strip-shaped hole 9. The hanging plate 10 is provided with a locking groove 12 for the hanging rod 11 to engage. The locking groove 12 is open on one side of the hanging plate 10 along the direction of rotation. By rotating the hanging plate 10 backward, the hanging rod 11 is disengaged from the locking groove 12, and then the second frame body 2 can be pulled upward and the fixed shaft 8 can be moved downward relative to the strip hole 9, and the distance between the top support 6 and the bottom support 3 is increased, so that the measuring cylinder can be taken out and placed in the bottom support 3; or after placing the measuring cylinder in the bottom support 3, the second frame body 2 is moved downward and the fixed shaft 8 can be moved upward relative to the strip hole 9, so that the top support 6 is buckled on the upper ends of multiple measuring cylinders, and then the hanging plate 10 is rotated forward to make the hanging rod 11 stuck in the locking groove 12, thereby limiting the second frame body 2 from moving up and down relative to the first frame body 1, so that the measuring cylinder remains clamped by the first frame body 1 and the second frame body 2, and the top support 6 is prevented from disengaging from the measuring cylinder upward.

[0031] The hanging plate 10 includes an eccentric wheel 13, which is rotatably mounted on the fixed shaft 8. An L-shaped hook 14 is integrally formed on the side of the eccentric wheel 13 that is farther from the fixed shaft 8. The hook 14 and the outer peripheral wall of the eccentric wheel 13 form a locking groove 12 with one side open. In the absence of external force, the weight of the eccentric wheel 13 causes the locking groove 12 to rotate downward from the fixed shaft 8, thereby preventing the hanging rod 11 from being disengaged from the locking groove 12.

[0032] A laterally extending retaining rod 15 is integrally formed or welded onto the outer side of the second connecting arm 7 above the strip-shaped hole 9. The retaining rod 15 is located on the rotation trajectory of the eccentric wheel 13. When the eccentric wheel 13 contacts the retaining rod 15, the hanging rod 11 disengages from the locking groove 12. After the slurry settling test is completed, the hanging plate 10 is first rotated backward to disengage the hanging rod 11 from the locking groove 12. After the hanging rod 11 is free from the locking groove 12, the hanging plate 10 is further rotated upward, causing the outer circumference of the eccentric wheel 13 to contact the retaining rod 15 and driving the second frame 2 to move upward as a whole, thereby easily removing the measuring cylinder from between the first frame 1 and the second frame 2.

[0033] A laterally extending limit pin 16 is integrally formed or welded on the outer side of the first connecting arm 4, and an open groove 17 is provided at the lower end of the second connecting arm 7 for the limit pin 16 to be inserted into. When the second frame 2 clamps multiple measuring cylinders downward, it drives the limit pin 16 to be inserted into the corresponding open groove 17, thereby limiting the rotation of the second frame 2 around the fixed axis 8, so that the second connecting arm 7 remains in a vertical state, and at the same time prevents the support 6 from deviating from the upper end of the measuring cylinder, thereby improving the stability of the first frame 1 and the second frame 2 in clamping the measuring cylinder.

[0034] In addition, when the second frame 2 is moved upward to remove the measuring cylinder from between the first frame 1 and the second frame 2, when the fixed shaft 8 moves to the lower end of the strip hole 9, the limit pin 16 disengages from the opening slot 17, and then the second frame 2 can be rotated around the fixed shaft 8 to make the top support 6 deviate from the upper end of the measuring cylinder. The top of the measuring cylinder is unobstructed, making it more convenient to remove the measuring cylinder. In this embodiment, a downwardly extending limit portion 18 is further provided on one side of the opening slot 17 along the width direction. When the fixed shaft 8 moves to the lower end of the strip hole 9 and one side of the limit pin 16 abuts the limit portion 18, the second connecting arm 7 remains in a vertical state, so that the second frame 2 can be moved downward to allow the limit pin 16 to accurately engage with the opening slot 17, while at the same time allowing the top support 6 to accurately engage with the upper end of the measuring cylinder.
