This device ensures low power and water consumption in the cement free calcium oxide determination experiment and maintains the cleanliness of the conductivity meter, avoiding measurement deviations caused by cleanliness issues. However, in actual use, the internal electronic components of the instrument can be affected by environmental temperature or humidity, leading to performance changes and a decrease in detection accuracy, thus affecting the test results. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a rapid determination device for free calcium oxide in cement, which aims to improve the problem that the electronic components inside the instrument in the prior art are affected by the ambient temperature or humidity, which leads to changes in performance, a decrease in detection accuracy, and an impact on the detection results.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rapid determination device for free calcium oxide in cement, comprising a determination device, a variable frequency fan fixedly connected to the rear left end of the determination device, an extraction pipe connected to the bottom right side of the variable frequency fan, a processing box connected to the right end of the extraction pipe, a filter plate fixedly connected to the rear side of the processing box, a heating rod fixedly connected to the rear right left end of the processing box, a three-way pipe connected to the top left side of the variable frequency fan, multi-hole nozzles connected to the top left and right sides of the three-way pipe, the rear side of the multi-hole nozzles fixedly connected to the rear side of the inner wall of the determination device, sealing doors rotatably connected to the left and right sides of the determination device, a discharge groove opened at the bottom of the sealing doors, and stabilizing mechanisms provided on the left and right sides of the inner bottom wall of the determination device.

[0006] The above technical solution involves using a variable frequency fan to draw in outside air while the sealed door is closed.

Subsequently, the drawn air is heated by a heating rod, ensuring a stable internal temperature for the instrument. The humid airflow is then discharged through the exhaust trough, reducing the impact of ambient temperature or humidity on the testing environment and improving the accuracy of the test results.

[0008] The above technical solution enables the swing cylinder to start, causing the front end of the swing cylinder to drive the rotating shell and the swing rod to swing. The swing rod can then drive the stabilizing plate to clamp the testing container. At the same time, with the connection of the torsion spring, the stabilizing plate can adapt to the outer wall of the container and rotate accordingly, thereby fixing the testing container, reducing the impact of shaking, and improving the stability of the container.

[0009] As a further description of the above technical solution: The stabilizing mechanism also includes two rubber pads, with the opposite sides of the two rubber pads respectively fixedly connected to adjacent sides of the stabilizing plate.

[0010] The above technical solution improves the fixing effect of the stabilizing plate by connecting the rubber pads.

[0011] As a further description of the above technical solution: A control switch is fixedly connected to the front right end of the measuring device. The control switch is electrically connected to the measuring device, the frequency converter fan, the heating rod, and the swing cylinder.

[0012] The above technical solution enables the device to be turned on and off when connected to a control switch.

[0013] As a further description of the above technical solution: A rubber ring is fixedly connected to the right end of the outer wall of the extraction tube, and the outer wall of the rubber ring is fixedly connected to the left side of the processing box.

[0014] The above technical solution improves the protection of the right end connection of the extraction tube by using the rubber ring connection.

[0015] As a further description of the above technical solution: Both of the sealed doors are fixedly connected to the front side with handles, and the middle of the handles is fixedly connected to rubber sleeves.

[0016] The above technical solution improves the anti-slip effect when using the handle by connecting the rubber sleeve.

[0017] As a further description of the above technical solution: Two sealing strips are fixedly connected to each adjacent side of the two sealing doors, and the multiple sealing strips are arranged symmetrically.

[0018] The above technical solution improves the sealing performance of the door when it is closed by connecting the sealing strip.

[0019] As a further description of the above technical solution: A display screen is fixedly connected to the front left end of the measuring device, and two connecting seats are fixedly connected to the bottom of both the left and right sides of the measuring device.

[0020] The above technical solution improves the stability of the device during operation by connecting it with the connector.

[0021] This utility model has the following beneficial effects: 1. In this utility model, with the sealed door closed, outside air is drawn in through the filter plate, and the airflow is filtered through the filter plate, so that larger particles can be filtered outside the collection box, avoiding interference from larger particles to the internal operation of the equipment. Subsequently, under the heating of the heating rod, the drawn airflow can be regulated and heated, thereby ensuring the stability of the internal temperature of the instrument, reducing the influence of ambient temperature or humidity on the detection environment, and improving the detection accuracy.

[0022] 2. In this utility model, the activation of the swing cylinder causes the rotating shell and the swing rod to swing, thereby driving the stabilizing plate to clamp the testing container under the swing of the swing rod. At the same time, under the connection of the torsion spring, the stabilizing plate can adapt to the outer wall of the container and rotate accordingly, thereby improving the stability of the container during testing.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a rapid determination device for free calcium oxide in cement, comprising a measuring device 1. A variable frequency fan 3 is fixedly connected to the rear left end of the measuring device 1. An extraction pipe 4 is connected to the bottom right side of the variable frequency fan 3, and a processing box 5 is connected to the right end of the extraction pipe 4. This allows air to be extracted through the processing box 5 under the operation of the variable frequency fan 3. A filter plate 6 is fixedly connected to the rear side of the processing box 5, and a heating rod 7 is fixedly connected to the rear right left end of the processing box 5. The airflow then passes through the filter plate 6 and the heating rod 7 for filtration and heating. The process ensures a constant temperature and cleanliness. A three-way pipe 8 is connected to the top left side of the variable frequency fan 3. The top left and right sides of the three-way pipe 8 are connected to multi-hole nozzles 9. The rear side of the multi-hole nozzles 9 is fixedly connected to the rear side of the inner wall of the measuring device 1. The filtered and heated airflow is sprayed through the multi-hole nozzles 9. Sealing doors 11 are rotatably connected to the left and right sides of the measuring device 1. A discharge groove 12 is opened at the bottom of the sealing door 11. The displaced gas is discharged through the discharge groove 12. A stabilizing mechanism 2 is provided on the left and right sides of the inner bottom wall of the measuring device 1. Specifically, with the sealing door 11 closed, the variable frequency fan 3 is activated to draw in external air, which is then purified by the filter plate 6. The filter plate 6 effectively intercepts and filters out larger particles in the air, preventing them from interfering with the internal measurement work of the equipment. The pre-filtered air then enters the heating area of ​​the heating rod 7, where it is heated to the required temperature. The heated and regulated air is then output into the equipment through the multi-hole nozzle 9. This process ensures timely replacement of the humid air inside the equipment, maintaining a stable internal temperature. The treated airflow is then discharged outside the equipment through the discharge slot 12, reducing the impact of changes in external ambient temperature or humidity on the detection environment, thereby improving the accuracy and reliability of the detection.

[0027] Reference Figure 1 , Figure 2 and Figure 5 The stabilizing mechanism 2 includes two fixed plates 201. The bottom walls of the two fixed plates 201 are fixedly connected to the left and right sides of the inner bottom wall of the measuring device 1, respectively. The top wall of the fixed plate 201 is fixedly connected to a swing cylinder 202, so that under the drive of the swing cylinder 202, the rotating shell 203 drives the swing rod 204 to swing. The front end of the swing cylinder 202 is fixedly connected to the rotating shell 203, and the top of the rotating shell 203 is fixedly connected to the swing rod 204. The top end of the swing rod 204 is rotatably connected to the stabilizing plate 205 through a torsion spring. Thus, under the swing of the swing rod 204, the stabilizing plate 205 swings synchronously to achieve the fixed clamping of the container to be tested. The front and rear sides of the stabilizing plate 205 are fixedly connected to protective plates 206. The protection of the side of the container is improved by multiple protective plates 206. Specifically, by activating the swing cylinder 202, its front end drives the rotating shell 203 and the swing rod 204 to swing. Subsequently, under the swing of the swing rod 204, the stabilizing plate 205 can be driven to clamp the container to be tested. At the same time, under the connection of the torsion spring, the stabilizing plate 205 can adapt to the outer wall of the container and rotate accordingly, which improves the stability of the container during testing, avoids the testing error caused by shaking, and ensures that the container can be stably fixed during the testing process, thereby improving the accuracy and reliability of the testing.

[0028] Reference Figure 1 , Figure 4 and Figure 5 The stabilizing mechanism 2 also includes two rubber pads 207, with the opposite sides of the two rubber pads 207 fixedly connected to adjacent sides of the stabilizing plate 205; a control switch 15 is fixedly connected to the front right end of the measuring device 1, and the control switch 15 is electrically connected to the measuring device 1, the frequency converter fan 3, the heating rod 7 and the swing cylinder 202 respectively; a rubber ring 10 is fixedly connected to the right end of the outer wall of the extraction tube 4, and the outer wall of the rubber ring 10 is fixedly connected to the left side of the processing box 5; Specifically, the rubber pad 207 improves the fixing effect of the stabilizing plate 205. The control switch 15, which is electrically connected to the measuring device 1, the variable frequency fan 3, the heating rod 7 and the swing cylinder 202 respectively, can turn the device on and off. The rubber ring 10 protects the connection at the right end of the extraction tube 4.

[0029] Reference Figure 1 , Figure 2 and Figure 3 A handle 13 is fixedly connected to the front side of each of the two sealing doors 11, and a rubber sleeve 14 is fixedly connected to the middle of the handle 13; two sealing strips 18 are fixedly connected to each adjacent side of the two sealing doors 11, and the multiple sealing strips 18 are symmetrically arranged; a display screen 17 is fixedly connected to the front left end of the measuring device 1, and two connecting seats 16 are fixedly connected to the bottom of the left and right sides of the measuring device 1. Specifically, the rubber sleeve 14 improves the anti-slip effect when using the handle 13, the multiple sealing strips 18 improve the sealing performance between the sealing door 11 and the measuring device 1, and the multiple connecting seats 16 improve the stability of the device during operation.

[0030] Working Principle: At startup, with the sealed door 11 closed, the variable frequency fan 3 draws in outside air through the filter plate 6. Larger particles are filtered outside the processing chamber 5, preventing interference with internal measurements. The drawn air is then heated by the heating rod 7 and output through the multi-hole nozzle 9, replacing the humid air inside the equipment and ensuring stable internal temperature. The replaced air is discharged through the discharge slot 12, reducing the impact of ambient temperature and humidity on detection accuracy. Furthermore, the swing cylinder 202 drives the rotating shell 203 and swing rod 204 to swing. The swing rod 204 then drives the stabilizing plate 205 to clamp the container to be tested. Connected by a torsion spring, the stabilizing plate 205 adapts to the container's outer wall, improving stability and preventing errors caused by shaking.
