DETAILED DESCRIPTION

[0021] The technical scheme of the utility model will be further described in detail in connection with specific embodiments. The parts not described in detail in the following embodiments of the utility model, such as repeated on-off of the relay control circuit, the electromagnet being able to attract the permanent magnet after the circuit is powered on, and the like, are all the prior art known or should be known by the person skilled in the art.

[0022] A high specific surface calcium hydroxide activity detection and evaluation device, as shown in the figure, comprises a titration support 1, a titration support frame 2, two burettes 3 and a vertical shaking support assembly 6. Figure 1 The titration support frame 2 is fixed on the titration support 1 in the vertical direction, and the two burettes 3 are installed on the titration support frame 2 through the installation support 4, with the burette openings of the burettes 3 arranged downward. One of the two burettes 3 is a hydrochloric acid burette 301 containing a hydrochloric acid solution, and the other is a standard hydrochloric acid burette 302 containing a standard hydrochloric acid solution.

[0023] The vertical shaking support assembly 6 is arranged on the titration support 1, and can support the conical flask 5 to lift and shake the solution in the flask in the vertical direction, so as to keep the mouth of the conical flask 5 always aligned with the burette opening of the standard hydrochloric acid burette 302. The vertical shaking support assembly 6 comprises a support table 601, a permanent magnet 603, an electromagnet 604 and a support rod 605. The support table 601 is arranged above the titration support 1 and parallel to the titration support 1 through the support rod 605, the permanent magnet 603 is fixed to the middle part of the bottom surface of the support table 601, and the electromagnet 604 is fixed to the upper surface of the titration support 1 below the permanent magnet 603.

[0024] The support rod 605 is slidably arranged in the titration support 1 in the vertical direction, the upper end of the support rod 605 is fixedly connected to the middle part of the bottom surface of the permanent magnet 603, and the lower end of the support rod 605 is slidably arranged in the buffer installation groove 101 arranged in the titration support 1 after passing through the hole arranged in the middle part of the electromagnet 604. A second spring 602 is arranged around the outer periphery of the support rod 605 between the permanent magnet 603 and the electromagnet 604, for resetting and lifting the support table 601 when it moves downward. The upper end of the second spring 602 is fixed to the bottom surface of the permanent magnet 603, and the lower end of the second spring 602 is fixed to the upper surface of the electromagnet 604.

[0025] A first spring 607 is arranged in the buffer installation groove 101, the lower end of the first spring 607 is fixed to the buffer installation groove 101, the upper end of the first spring 607 is arranged around the lower end of the support rod 605 passing through the hole, and the upper end of the first spring 607 is fixedly connected to the outer periphery of the lower end of the support rod 605.

The recess 6011 can keep the conical flask 5 stable on the support table 601 and prevent it from moving out of the support table 601 with the support table 601.

[0029] Further, two mounting brackets 4 are mounted on the titration support 2, one of which is used to mount and fix the hydrochloric acid burette 301, and the other is used to mount and fix the standard hydrochloric acid burette 302. The mounting bracket 4 comprises a mounting sleeve 401 and a mounting flat rod 402.
