[0002] Flocculant is a chemical used in water treatment that helps to aggregate solid particles suspended in water into larger clumps so that they can be more easily separated from the water. The produced flocculants need to be quality inspected, including indicators such as the crystal size of the aggregated solid particles.

[0003] At present, the test of flocculants is mainly conducted by observing the appearance and particle size of the flocculants after the reaction. At present, the reaction of flocculants is usually tested using test tubes. However, the test tube test needs to be transferred to multiple test chambers for testing at different ambient temperatures, which is troublesome. Therefore, a device for flocculant production testing is proposed to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] See also Figure 1-4 In this embodiment, a device for flocculant production test includes a bracket 1 and an extension arm 2 movably mounted on the bracket 1. A clamp is installed at the end of the extension arm 2 for clamping a test tube for testing the flocculant.

[0025] In this embodiment, the clamp includes a fixed plate 3 fixedly mounted on one end of the extension arm 2, a clamp 5 slidably connected to the fixed plate 3, and a spring rod connected between the clamp 5 and the fixed plate 3. The inner walls of the clamp 5 and the fixed plate 3 are both recessed in an arc shape to facilitate stable contact with the test tube.

[0026] It should be noted that the spring rod includes a sliding rod 4 fixedly mounted on a side of the clamping plate 5 facing the fixed plate 3, a limiting plate 6 fixedly mounted on the end of the sliding rod 4, and a compression spring 7 arranged between the limiting plate 6 and the fixed plate 3, wherein the sliding rod 4 penetrates and is slidably connected to the fixed plate 3, and the diameter of the limiting plate 6 is larger than the diameter of the hole in the fixed plate 3 penetrated by the sliding rod 4, so that the clamping plate 5 cannot slide away from the fixed plate 3.

[0027] In order to heat up or cool down the fixture, a heat conducting plate 8 is fixedly installed on the outside of the clamp 5 in this embodiment. The heat conducting plate 8 is provided with a mounting structure for providing a mounting position, and a semiconductor cooling plate 17 for cooling or heating is provided on the mounting structure.

[0028] In this embodiment, the mounting structure includes a screw member installed on the heat conduction plate 8, a movable block 12 connected to the screw member, a mounting frame 14 rotatably connected to the movable block 12, and a swing rod 16 for limiting the mounting frame 14, wherein a rotating bearing 15 is also fixedly mounted on the heat conduction plate 8, and one end of the swing rod 16 is rotatably connected to the rotating bearing 15.

[0029] It should be noted that the screw component includes two mounting platforms 9 fixedly mounted on the heat conduction plate 8, a screw 10 rotatably connected to the two mounting platforms 9, and a screw motor 11 fixedly mounted on the heat conduction plate 8. The output end of the screw motor 11 is fixedly connected to the screw 10, and the screw motor 11 can pull the screw 10 to rotate. In addition, the movable block 12 is rectangular and fits the heat conduction plate 8 to slide. At the same time, the movable block 12 is threadedly connected to the screw 10, so that the movable block 12 can be stably pulled to slide and change its position when the screw 10 rotates.

[0030] In this embodiment, a platform 13 is fixedly installed on the outside of the movable block 12, and one end of the mounting frame 14 extends and is connected to the platform 13 at the upper end of the movable block 12, so that the mounting frame 14 can be placed horizontally on the surface of the mounting table 9, and one end of the swing rod 16 is rotatably connected to the middle part of the mounting frame 14. At this time, the mounting frame 14 can be rotated relative to the connection of the swing rod 16 to achieve flipping under the traction rotation of one end.

[0031] In this embodiment, the swing rod 16 is an L-shaped rod, and the height of the bent end of the swing rod 16 is aligned with the mounting platform 9, so that the swing rod 16 can adapt to the edge connection of the mounting frame 14 in a flat state.

[0032] It should be noted that a rotary joint 18 is also installed on one end of the heat conducting plate 8 , and the rotary joint 18 can facilitate the effective connection of the semiconductor cooling plate 17 in the flipped state and avoid the entanglement of the wires of the semiconductor cooling plate 17 .

[0033] In order to improve the effective contact between the semiconductor cooling sheet 17 and the heat conducting plate 8 , the surface of the heat conducting plate 8 in this embodiment is convex in a direction away from the clamping plate 5 and is in contact with the semiconductor cooling sheet 17 .

[0034] The working principle of the above embodiment is:

[0035] By placing the test tube with the solution to be tested between the clamp 5 and the extension arm 2, the clamp 5 is pushed by the compression spring 7 to move toward the extension arm 2 to clamp the test tube. By adding the flocculant into the test tube for reaction, the semiconductor refrigeration plate 17 is energized at the same time. At this time, one side of the semiconductor refrigeration plate 17 contacts the heat conduction plate 8, so that the clamp 5 used to clamp the test tube is heated up, thereby changing the reaction efficiency of the flocculant under different environments. When changing the reaction temperature, the screw motor 11 is driven, and the screw motor 11 drives the screw 10 on the output end to rotate. The screw 10 is threadedly engaged with the movable block 12 during rotation. At this time, the movable block 12 is movable relative to the screw 10, and one end of the mounting frame 14 connected to the movable block 12 is pulled by the movable block 12, thereby rotating relative to the connecting part of the swing rod 16 to complete the flipping direction, that is, the clamp 5 used to clamp the test tube is cooled.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
