Description

Technical Field

[0001] This utility model relates to the field of cement testing technology, and in particular to a cement specific surface area testing device. Background Technology

[0002] With economic development, the construction industry has developed rapidly. Cement is a very important material in the construction field, and it affects the overall safety of buildings.

[0003] Cement specific surface area refers to the total surface area of ​​a unit mass of cement powder. The basic principle of a cement specific surface area meter is to measure the resistance encountered by a certain amount of air when passing through a compacted powder layer with a certain porosity and thickness.

[0004] Currently, the specific surface area of ​​cement is usually measured using a Blaine surface area analyzer. However, due to the cumbersome process, the measurement efficiency is very low, and the accuracy is easily affected by the testing environment. Therefore, there is a need for improvement. Utility Model Content

[0005] This invention provides a cement specific surface area testing device that can avoid the influence of the external environment on the accuracy of testing, ensure the accuracy of test results, effectively increase the measurement efficiency, and meet higher testing requirements. It solves the technical problems of the existing cement specific surface area measurement methods being relatively simple, having low detection efficiency, and having test results that are easily affected by the environment, thus failing to meet higher testing requirements.

[0006] The above-mentioned technical problem of this utility model is solved by the following technical solution: A cement specific surface area testing device includes a workbench, with different positions on the workbench designated as different working positions. Each working position includes a sample cylinder assembly position, a cement weighing position, a cement compaction position, and a measuring position. A measuring box corresponding to the measuring position is located in the center of the workbench. The measuring box contains a measuring device and a control device to ensure a stable measuring environment. Before measurement, multiple operators sit on one side of the sample cylinder assembly position, cement weighing position, cement compaction position, and measuring position on the workbench. Operators at different working positions are responsible for different tasks, including assembling the sample cylinder, weighing and loading the cement, compacting the cement, and measuring the specific surface area. By dividing the work into multiple steps, the efficiency of the measurement is increased, and the control device inside the measuring box ensures a stable environment within the measuring box, guaranteeing the accuracy of the measurement results.

[0007] Preferably, the workbench surface is provided with a ring-shaped turntable, on which several bases are spaced apart, and sample cylinders are placed inside the bases. The ring-shaped turntable has several bases spaced apart, allowing operators at different workstations to perform different operations.

[0008] Preferably, the bottom of the worktable is equipped with a motor for controlling the rotation of the turntable. The motor drives the turntable to rotate, and the rotation speed of the turntable can be adjusted as needed. The motor can be started and stopped independently, and can also be set to work intermittently as needed.

[0009] Preferably, the control device includes a temperature sensor installed inside the measuring chamber, with independent hot and cold air ducts inside the measuring chamber, and a temperature control box connected to the hot and cold air ducts on the outside of the measuring chamber. During the measurement process, the temperature sensor monitors the environment inside the measuring chamber and adjusts the temperature inside the measuring chamber through the temperature control box based on the monitoring results; the temperature control box achieves heating or cooling through a compressor, resistance heating, fan, and other structures, and can be adjusted independently as needed.

[0010] Preferably, the control device further includes a humidity sensor installed inside the testing chamber, which is equipped with an independently controlled humidifier. During the testing process, the humidity sensor monitors the environment inside the testing chamber and adjusts the humidity inside the testing chamber through the humidifier based on the monitoring results, ensuring a stable environment inside the testing chamber during the testing process, avoiding the influence of environmental factors on the testing results, and thus ensuring the accuracy of the testing results.

[0011] Preferably, the control device also includes a display fixed to the outside of the measuring chamber, which is connected to the temperature and humidity sensors. The display can show the temperature and humidity inside the measuring chamber in real time, facilitating automatic adjustment of the internal temperature or humidity as needed or through a program.

[0012] Preferably, the measuring chamber has an operating window on its surface, and a soft rubber baffle is provided on the operating window. Operators can insert their hands into the measuring chamber through the operating window to perform operations, ensuring the stability and consistency of the environment inside the measuring chamber to the greatest extent possible.

[0013] Preferably, the measuring chamber is transparent. A transparent measuring chamber allows operators to easily observe the internal measuring results and perform the operation.

[0014] Preferably, the workbench surface is equipped with several storage bins located at different work positions. These storage bins are used to store cement, compaction rods, and tools. The storage bins are used to store cement samples, compaction rods, filter paper, and other necessary tools, and are placed at different work positions.

[0015] Preferably, a weighing device is provided at the cement weighing position of the workbench.

[0016] Therefore, the cement specific surface area testing device of this utility model has the following advantages: it can avoid the influence of the external environment on the test accuracy, ensure the accuracy of the test results, divide the cumbersome tools into multiple separate steps, effectively increase the measurement efficiency, and can meet higher testing requirements.
