Description

Technical Field

[0001] The utility model relates to the technical field of electronic moisture meters, and particularly relates to a detection workbench for a moisture meter. Background Technique

[0002] A moisture meter is an instrument for detecting the moisture content in various samples such as solids and gases. Moisture meters can be widely used in various industries that require moisture determination, such as the production and research processes in industries such as food, medicine, seeds, tobacco, chemical engineering, agriculture and forestry, papermaking, and textiles. The determination principle of a moisture meter is mainly based on the evaporation and loss of moisture in substances. According to the test principle, it is mainly divided into physical determination and chemical determination. Among them, physical determination includes methods such as the loss of weight method and the distillation layering method. Based on the physical weight loss principle, the determination method of quickly heating and evaporating moisture has the advantages of simple operation and high sensitivity, and is a commonly used method for moisture determination. The drying weighing method meter can be used to measure the moisture content of substances.

[0003] However, when the heating body on the existing meter is closed, it often makes hard contact with the workbench panel under its own gravity, which is likely to cause damage to the instrument. In view of this, we propose a detection workbench for a moisture meter. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a detection workbench for a moisture meter to solve the problems raised in the above background technique.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-4As shown in the figure, the purpose of this embodiment is to provide a detection workbench for a moisture meter, which is composed of a heating main body 1, an aluminum weighing pan 2, a sample pan support 3, a fixed base 4, a workbench panel 5, a housing component 6, a tension spring component 7, a display 8, a weighing main body 9, and a thimble 10. The heating main body 1 is fixedly connected to the thimble 10, and the heating main body 1 and the weighing main body 9 are connected by a hinge. The aluminum weighing pan 2 is placed above the sample pan support 3, and the sample pan support 3 is fixed above the workbench panel 5 through the fixed base 4. The workbench panel 5 is placed above the housing component 6, and the housing component 6 is placed above the weighing main body 9 and the tension spring component 7. The tension spring component 7 is connected between the housing component 6 and the heating main body 1, and the display 8 is fixedly connected to the weighing main body 9.

[0020] It should be added that the heating main body 1 is composed of a heating cover provided on the periphery and a halogen lamp installed in the heating cover. The halogen lamp heating can reach the maximum heating power in the shortest time, and the rapid heating time of the sample helps to improve the measurement efficiency.

[0021] It should be noted that the fixed base 4 and the workbench panel 5 are fixed by screws.

[0022] There are two tension spring components 7, which are respectively arranged on both sides of the housing component 6. There are two thimbles 10, which are respectively arranged at fixed positions on both sides of the heating main body 1.

[0023] The weighing main body 9 includes a support 91 and a ten-thousandth precision weighing sensor 92. The ten-thousandth precision weighing sensor 92 is arranged below the weighing main body 9, and the support 91 is arranged below the weighing main body 9.

[0024] The tension spring component 7 includes a support rod 71 and a spring 72. The support rod 71 and the spring 72 are fixedly connected, and the spring 72 is fixed on the housing component 6.

[0025] It should be noted that the end of the support rod 71 is connected to the heating main body 1, and the support rod 71 is made of an elastic metal rod. When the heating main body 1 is closed, the support rod 71 can be pulled, thereby pulling the spring 72 and stretching the spring 72, so as to reduce the impact when the heating main body 1 is closed.

[0026] It should be added that a docking groove is provided at the position on the surface of the housing component 6 facing the ejector pin 10.

Install the aluminum weighing pan 2 on the sample pan support 3. Thus, the installation is completed.

[0028] The usage steps are as follows: Place the sample to be detected on the aluminum weighing pan 2. Then close the heating main body 1 to make it in a completely closed state with the workbench panel 5. Then start the heating main body 1 to quickly heat the sample to be detected to evaporate the moisture on it. Use the weighing sensor 92 with a precision of one ten-thousandth to measure the mass of the sample to be detected after heating. The moisture content in the sample can be detected through the mass difference before and after.
