Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum powder purity detection, and in particular relates to a sample storage device for fine aluminum powder purity detection. Background Art

[0002] During the titration method for the purity test of fine aluminum powder, different types of containers are used to store the raw material samples. During the test, the samples need to be repeatedly heated and cooled. For example, after adding hydrochloric acid and ammonium persulfate, the temperature needs to be raised and boiled. After cooling, sodium hydroxide is added, and the mixture is boiled again, and then cooled to room temperature. During this process, the container used to store the raw material samples is a beaker, followed by a volumetric flask for constant volume.

[0003] When using a beaker to store raw materials for testing, there are the following defects: the existing method of heating the raw materials in the beaker includes using an alcohol lamp or electric heating to provide high temperature, but part of the heat is directly transmitted to the raw materials through the cup body, and the other part heats the air and then is lost, resulting in the raw materials being heated for a long time, which increases the time required for aluminum powder detection. Secondly, the cooling method after heating mainly uses a static method to wait for the raw materials in the beaker to slowly cool down, further extending the detection time.

[0004] Therefore, in the process of detecting the purity of fine aluminum powder, the method of storing raw materials in beakers will result in low detection efficiency. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides a sample storage device for detecting the purity of fine aluminum powder.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A sample storage device for detecting the purity of fine aluminum powder comprises an upper shell, the bottom of which is rotatably connected to a lower shell, the upper shell and the lower shell are both cylindrical in shape, the upper shell and the lower shell have the same diameter, the bottom of the upper shell and the top of the lower shell fit together, the top of the upper shell is provided with an opening, a cup body is fixedly connected to the opening of the upper shell, a heating coil located at the bottom of the cup body is fixedly connected to the bottom of the inner cavity of the upper shell, a gap is provided between the inner wall of the upper shell and the cup body, through holes are provided on both sides of the bottom of the upper shell and on both sides of the top of the lower shell, the two through holes of the upper shell correspond to the two through holes of the lower shell respectively, a plurality of air holes are provided on the circumferential surface of the lower shell, a fan is fixedly connected to the bottom of the inner cavity of the lower shell, and the air outlet of the fan is connected to a through hole of the lower shell through an air duct.

[0008] Furthermore, a fixing plate is fixedly connected to the upper part of the circumferential surface of the lower shell, the top of the fixing plate extends to the lower part of the circumferential surface of the upper shell, a groove is opened on the side of the fixing plate, and a positioning block adapted to the fixing plate groove is fixedly connected to the lower part of the circumferential surface of the upper shell.

[0009] Furthermore, the inner wall of the upper shell is provided with a rock wool insulation layer.

[0010] Furthermore, a partition is fixedly connected inside the lower shell.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. By rotatably forming the upper shell and the lower shell, a closed space can be formed in the upper shell. When the heating coil heats the raw materials in the cup, the hot air in the gap is not easy to lose, and wraps the cup to conduct heat, so that the raw materials receive more heat and the boiling time is shorter, which reduces the time required for aluminum powder detection. Secondly, the upper shell and the lower shell can be connected through a through hole, so that the airflow generated by the fan in the lower shell is blown into the upper shell, which speeds up the cooling of the raw materials and further reduces the detection time. The device is used to store raw materials for detection, which can improve the detection efficiency.

[0013] 2. The fixing plate and the positioning block make it easy for the inspectors to judge whether the through holes on the upper and lower sides correspond to each other. The rock wool insulation layer improves the insulation effect of the upper shell, further reducing the internal heat loss. The partition separates the lower shell into two independent spaces, so that the upper shell can blow back the hot air flow in the lower shell to avoid being sucked in again by the fan.

[0020] A fixing plate 7 is fixedly connected to the upper part of the circumferential surface of the lower shell 2, the top of the fixing plate 7 extends to the lower part of the circumferential surface of the upper shell 1, a groove is provided on the side of the fixing plate 7, and a positioning block 8 adapted to the groove of the fixing plate 7 is fixedly connected to the lower part of the circumferential surface of the upper shell 1.

[0021] The inner wall of the upper shell 1 is provided with a rock wool insulation layer.

[0022] A partition plate 9 is fixedly connected inside the lower shell 2 .

[0023] Working principle: In the utility model, the cup body 3 is a heat-resistant glass cup. When placing the raw materials, the aluminum powder sample raw materials and other raw materials can be placed in the cup body 3. When the raw materials need to be heated, the upper shell 1 and the lower shell 2 are rotated until the through holes on the upper and lower sides are misaligned, and the top of the lower shell 2 blocks the two through holes of the upper shell 1, so that a closed space can be formed in the upper shell 1. When the heating coil 4 is powered on to heat up and the raw materials in the cup body 3 are heated, the hot air in the gap is not easy to lose, and the heat is conducted around the cup body 3 until the raw materials are boiled for a certain period of time. When the raw material is cooled, the upper shell 1 and the lower shell 2 are rotated in opposite directions, and the position of the positioning block 8 is observed until the positioning block 8 is inserted into the groove of the fixing plate 7. At this time, the through holes on the upper and lower sides are connected, and the fan 5 is energized to generate airflow. The air duct 6 conveys the airflow from a through hole of the lower shell 2 through a through hole of the upper shell 1 and transports it to the upper shell 1, and then discharges the upper shell 1 from another through hole. The flowing airflow takes away the heat in the upper shell 1 and cools the cup body 3. Moreover, the hot airflow blown back from the upper shell 1 to the lower shell 2 is blocked by the partition 9 and will not be re-inhaled by the fan 5.

Therefore, it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model, and any figure marks in the claims should not be regarded as limiting the claims involved.
