[0002] Cement grinding aids are a class of additives widely used in cement production. Their main function is to improve mill efficiency, reduce energy consumption, and improve cement performance during the grinding process. Moisture content is a crucial factor affecting the performance and stability of cement grinding aids; therefore, accurate determination of their moisture content is essential.

[0003] A search revealed that Chinese patent CN208459207U discloses a "Moisture Analyzer for Detecting the Moisture Content of Cement Grinding Aids," comprising: a base with a feed inlet on one side, an exhaust port communicating with the interior of the chamber on one side of the feed inlet, infrared heating tubes on both sides of the inner wall of the chamber, a conveyor belt evenly spaced between two sets of infrared heating tubes, a weight sensor at the bottom of the chamber's inner cavity, a touch screen mounted on the outer wall of the base, a groove on the upper surface of the base, and guide posts at the four corners of the top of the base, with clamping nuts screwed onto the outer wall of the guide posts; however, the following defects still exist:

[0004] (1) When using a moisture analyzer for detecting the moisture content of cement grinding aids, the cement grinding aids may clump due to prolonged standing before testing, which may affect the accuracy of the test data.

[0005] (2) When using the moisture analyzer for detecting the moisture content of cement grinding aids, the above application may result in discrepancies between the test data and the correct data due to the uneven distribution of moisture inside the cement grinding aids and the test being conducted only once. Therefore, a moisture measuring device for cement grinding aids is proposed. Utility Model Content

[0006] The purpose of this invention is to address the problem that cement grinding aids may clump together due to prolonged standing before testing, which could affect the accuracy of test data.

[0028] like Figure 1 , Figure 2 , Figure 3 As shown, this embodiment proposes a moisture measuring device for cement grinding aid, including a sealed box 1. A support leg 2 is fixedly installed at the bottom of the sealed box 1, and a fixing frame 3 is fixedly installed at the top of the sealed box 1. A detection device 4 is provided inside the sealed box 1. The detection device 4 includes a U-shaped frame 40, which is fixedly installed on the inner wall of the sealed box 1. A discharge port 41 is fixedly installed on the surface of the U-shaped frame 40, and a guide pipe 42 is fixedly installed at the bottom of the discharge port 41. A solenoid valve 43 is fixedly installed on the circumferential surface of the guide pipe 42. A square bucket 44 is fixedly installed on the surface of the sealed box 1. The solenoid valve 43 is remotely controlled by an electrical signal, reducing manual operation and improving the degree of automation.

[0029] like Figure 4 As shown, in a preferred embodiment, based on the above method, a guide plate 45 is fixedly installed on the inner wall of the square barrel 44, a feeding trough is opened at the bottom of the square barrel 44, and a fixing block 46 is fixedly installed on the inner wall of the square barrel 44. The guide plate 45 is designed to simultaneously measure the moisture content of multiple samples or cement grinding aids at multiple different locations in one operation, which significantly improves the measurement efficiency.

[0030] like Figure 4 As shown, in a preferred embodiment, based on the above method, an infrared detection head 47 is further fixedly installed at the bottom of the fixing block 46, a slide rail 48 is fixedly installed at the bottom of the sealed box 1, and a sliding plate 49 is slidably installed on the inner wall of the slide rail 48. The infrared detection head 47 can usually provide measurement results in a shorter time, which significantly improves the detection efficiency compared with traditional chemical analysis or drying methods.

[0031] like Figure 1 , Figure 4As shown, in a preferred embodiment, based on the above method, the number of fixing blocks 46 and infrared detection heads 47 are each set to two, and they are distributed at the top and bottom of the square barrel 44. The number of slide rails 48 is set to two, and they are symmetrical along the vertical central axis of the sealed box 1. The number of support legs 2 is set to four, in pairs, and they are symmetrical along the vertical central axis of the sealed box 1.

[0032] like Figure 1 , Figure 5 As shown, in a preferred embodiment, based on the above method, a uniform device 5 is further provided on the top of the sealed box 1. The uniform device 5 includes a circular barrel 50, which is fixedly installed on the top of the sealed box 1.

[0033] like Figure 5 As shown, in a preferred embodiment, based on the above method, the top of the circular barrel 50 is further fixedly installed with the fixed end of the motor 51, the output end of the motor 51 is fixedly installed with the rotating column 52, and the circumferential surface of the rotating column 52 is fixedly installed with the fan blade 53. The fan blade 53 reduces the measurement error caused by uneven moisture distribution and improves the reliability of the moisture measurement results.

[0034] like Figure 5 As shown, in a preferred embodiment, based on the above method, a threaded column 54 is fixedly installed at the bottom of the rotating column 52, a U-shaped rod 55 is threadedly installed on the circumferential surface of the threaded column 54, and a uniform plate 56 is fixedly installed at the top of the U-shaped rod 55. The number of uniform plates 56 is set to two, and they are symmetrical along the vertical central axis of the rotating column 52. The U-shaped rod 55 can promote the more complete dispersion of particles in the cement grinding aid and avoid the cement grinding aid from clumping.

[0035] Working principle:

[0036] Specifically, when using this testing device 4: First, when the device is needed, a professional worker will test it. After confirming that it is correct, the cement grinding aid will fall into the guide pipe 42 through the feed port 41. At this time, the solenoid valve 43 will open when it detects a certain weight. The cement grinding aid will then continue to fall into the square bucket 44 through the guide pipe 42. The cement grinding aid will then fall onto the surface of the guide plate 45. Since the shape of the guide plate 45 is different, the cement grinding aid will be guided to the plane of the guide plate 45. At this time, the infrared detection head 47 will detect the cement grinding aid. Since the moisture content of the cement grinding aid may be different at the top and bottom during the flow, the infrared detection head 47 at the bottom of the square bucket 44 can test the moisture grinding aid falling from the bottom. By setting multiple detection points, moisture data from different locations can be obtained, which helps to identify the uneven distribution of moisture in the cement grinding aid. After the test is completed, a professional worker will slide the slide plate 49 to remove the cement grinding aid. Data from multiple sample locations can be obtained in one test, reducing the time for sample processing and preparation each time and improving the overall efficiency of the measurement.

[0037] Because cement grinding aids can clump together if left to stand for a long time, they must be thoroughly mixed before testing. During this process, motor 51 drives rotating column 52, which in turn drives fan blade 53, threaded column 54, and U-shaped rod 55. The U-shaped rod 55 then moves up and down, causing uniform plate 56 to move up and down. Clumping of the cement grinding aid can lead to differences in sample characteristics at different locations. Thorough mixing ensures a more uniform distribution of the cement grinding aid's components, guaranteeing more representative moisture results during measurement and avoiding localized moisture deviations caused by clumping.

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
