Description
Technical Field
[0001] The utility model relates to the technical field of density detection devices, in particular to a device for detecting the true density of powder materials such as spherical silicon micropowder. Background Art
[0002] A powder densitometer is an instrument used to measure the density of powders. It usually uses the Archimedes displacement method to calculate the density of a sample by measuring its mass in air and water.
[0003] Existing powder material densitometers generally only require placing the sample on the measuring table and pressing the measurement button to quickly obtain the density result. The density value of the sample is directly displayed digitally. However, placing the sample directly on the measuring table cannot ensure that the sample is in the center position of the measuring table, thereby unable to guarantee the accuracy of the measurement result, resulting in reduced measurement accuracy. Therefore, we have launched a new true density detection device for powder materials such as spherical silica powder. Utility Model Content

[0009] Preferably, the two limiting plates are both located in the limiting groove.
[0010] By adopting the above technical solution: placing the powder material to be tested at the center of the test bench through two limit plates, it can be ensured that the sample is subjected to uniform force and action, avoiding large errors in the test results due to position deviation, and improving the accuracy of the test results.
[0011] Preferably, the two limiting pads are symmetrically distributed on the left and right.
[0012] By adopting the above technical solution, the limiting pad can avoid damage to the sample to be measured when the limiting plate limits the sample to be measured.
[0013] Preferably, the ends of several No. 2 screws are respectively tightly fitted with the outer surfaces of several containing cups.
[0014] By adopting the above technical solution, the holding cup can be limited in the placement cylinder.

The sample to be tested is placed in the center of the test bench through the two limit plates. This ensures that the sample is subjected to uniform force and action, avoids large errors in the test results due to position deviation, and improves the accuracy of the test results.

The end of the positioning plate 8 away from the movable sleeve 7 is fixedly connected to the limiting pad 9, the left and right ends of the test bench 1 are fixedly connected to three fixed blocks 10, several fixed blocks 10 are fixedly connected to the end away from the test bench 1 with a placement tube 11, several placement tubes 11 are provided with a holding cup 12 inside, several placement tubes 11 are connected with a No. 2 screw 13 on the side away from the fixed block 10, the four corners of the lower end of the test bench 1 are fixedly connected with an anti-slip pad 14, a display screen 15 is provided on the left front end of the test bench 1, and a button 16 is provided on the right front end of the test bench 1.
[0030] In this embodiment, the lower end of the limiting ring 4 does not contact the placement plate 2, the two limiting plates 8 are both located in the limiting groove 5, and the two limiting pads 9 are symmetrically distributed.
[0031] Through the above scheme: the sample to be tested is placed on the placement plate 2 and placed in the limit groove 5, and by rotating the two No. 1 screws 6 at the same time, the two No. 1 screws 6 respectively move relative to the two limit plates 8 through the two movable sleeves 7, so that the two limit pads 9 are fitted with the sample to be tested, and the sample to be tested is placed in the center position of the test table 1 through the two limit plates 8, which can ensure that the sample is subjected to uniform force and action, avoid large errors in the test results due to position deviation, improve the accuracy of the test results, and each test can be carried out under the same conditions, which is conducive to obtaining stable test data.
[0032] In this embodiment, the ends of the plurality of No. 2 screws 13 are respectively tightly fitted with the outer surfaces of the plurality of holding cups 12 , and the four anti-slip pads 14 are all made of rubber.
[0033] Through the above scheme: when there are many samples to be tested, by sticking labels on the outer surfaces of several placement tubes 11 respectively, and placing the samples to be tested in the corresponding placement tubes 11 through the holding cups 12, and at the same time limiting the holding cups 12 in the placement tubes 11 through the No. 2 screw 13 to wait for testing, the testing order of the samples to be tested can be orderly, avoiding detection confusion.

The pycnometer is then placed back on the test bench 1 and memorized by button 16. The true density of the sample will be displayed by the test bench 1, ensuring that the sample is subjected to uniform force and action during the measurement process, thereby avoiding detection errors caused by position deviation and improving the accuracy of the test results. At the same time, each test is carried out under the same conditions, which helps to obtain stable and reliable test data. When a large number of samples need to be tested, in order to improve the detection efficiency, different labels can be affixed to the outer surfaces of several placement tubes 11 to identify and distinguish different samples. Then, the samples to be tested are placed in the corresponding placement tubes 11 through the holding cups 12, and the No. 2 screw 13 is used to fix the position of the holding cup 12 in the placement tube 11 to ensure that the sample will not move or fall over before testing, so that the testing order of the samples to be tested is orderly, avoiding detection errors or delays caused by confusion.
