Description

Technical Field

[0001] The utility model relates to the technical field of low-alkali cement alkali content detection, in particular to a device for detecting the alkali content of low-alkali cement. Background Art

[0002] Low-alkali cement refers to cement with a low content of alkali metal oxides. The total alkali content is measured as sodium oxide equivalent. Low-alkali cement must have a total alkali content of less than 0.6%. Low-alkali cement can be any type of Portland cement. Any alkali content below 0.6% is considered low-alkali cement. Its production requires low-alkali clinker, low-alkali gypsum, and low-alkali mineral admixtures. Low-alkali clinker must be made from low-alkali limestone and other low-alkali raw materials. Low-alkali cement has the following characteristics: High corrosion resistance: Due to its low alkali content, it is less likely to react with metal materials such as rebar, effectively preventing rebar corrosion. Therefore, it has broad application prospects in applications requiring high corrosion resistance, such as marine engineering and chemical plants. Low shrinkage: Its low shrinkage reduces cracking and helps improve the integrity of concrete structures. High adaptability: Its increased adaptability to various admixtures and aggregates allows for greater flexibility in the selection of raw materials in cement formulation design, resulting in better performance. With the development of society, the alkali content of low-alkali cement needs to be tested using testing equipment.

[0003] Existing equipment such as CN221100743U, a device for detecting the alkali content of low-alkali cement, includes a workbench, a measuring device for detecting the alkali content installed on the upper end of the workbench, a bracket fixed above the workbench, a purification device fixed at the upper end of the bracket, and two air inlets connected to the lower end of the purification device; the utility model is provided with two smoke extraction pipes rotatably arranged above the cement alkali content measuring device, so that the white smoke generated when the low-alkali cement sample is heated can be quickly extracted into the purification device, reducing the possibility of the white smoke mixing into the air, and when the lower end of the smoke extraction pipe is rotated away from the top of the measuring device, the air inlet is blocked by the inner wall of the air inlet, preventing the drawn-in white smoke from flowing back into the air again, and making it convenient to take and place the cement sample.

[0004] When a worker needs to test the alkali content in low-alkali cement, the worker inserts the probe of the detection device into the low-alkali cement so that the detection device can detect the low-alkali cement. However, when the worker stores the detection device, the worker needs to remove the probe from the instrument first, which requires the worker to rotate the connecting component of the probe multiple times, thereby causing inconvenience to the worker when storing or using the detection device.
