Description

Technical Field

[0001] This utility model relates to the field of environmental testing technology, and more specifically, to a sample drying device for environmental testing laboratories. Background Technology

[0002] Environmental monitoring involves detecting the content and emissions of various substances that affect humans and the environment, tracking changes in environmental quality, determining environmental quality levels, and providing a foundation and guarantee for environmental management and pollution control. Simply put, understanding the environmental level and conducting environmental monitoring are prerequisites for all environmental work. Environmental monitoring typically includes background investigation, plan determination, optimized site selection, on-site sampling, sample transportation, experimental analysis, data collection, and analysis and synthesis. In general, it is a process of obtaining information through planning, sampling, analysis, and synthesis.

[0003] Currently, in existing environmental monitoring experiments, samples are often placed in a drying oven during drying. The drying oven is equipped with adjustable support components, which can be used to dry the samples with a hot air blower. However, during the drying process, the heat distribution in the drying space is uneven, with some areas overheating while other areas are underheated. This not only affects the drying effect but may also lead to energy waste, prolong the drying time, and reduce work efficiency.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in related technologies, the purpose of this utility model is to propose a sample drying device for environmental testing laboratories to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A sample drying device for an environmental testing laboratory includes: a drying oven, a hot air box for outputting hot air connected to one side of the drying oven, the hot air box having a cavity structure, and a support plate provided inside the hot air box, and a plurality of electric heating tubes provided inside the support plate;

[0008] A fan is provided on one side of the hot air box, with the output end of the fan facing the inside of the hot air box. A flow port is provided on the other side of the hot air box, and the hot air inside the hot air box is output to the drying oven through the flow port via the fan to dry the sample.

[0009] Furthermore, the drying oven is equipped with a storage component, and the sample is placed on the storage component.

[0010] Furthermore, the flow port is located between the drying chamber and the hot air chamber.

[0011] Furthermore, a loading plate is provided on one side of the fan.

[0012] Furthermore, the electric heating tube has a U-shaped structure, and there is a gap between adjacent electric heating tubes.

[0013] Furthermore, the hot air box is provided with a removable cover at the top.

[0014] The beneficial effects of this utility model are:

[0015] This invention places the sample in a drying oven, and provides heat through the electric heating tube of the hot air box, while a fan conducts hot air to the drying oven through the vent to dry the sample. The heat is fully distributed in the drying oven, which can quickly raise the temperature inside the drying oven. This not only increases the drying temperature inside the drying oven, but also ensures uniform heat distribution, resulting in good drying effect for the sample. All parts of the sample can be fully dried with uniform heat distribution, shortening the drying time and improving the drying efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0024] According to an embodiment of the present invention, a sample drying device for an environmental testing laboratory is provided.

[0025] like Figures 1-2 As shown, a sample drying device for an environmental testing laboratory includes: a drying oven, a hot air box 1 for outputting hot air connected to one side of the drying oven, the hot air box 1 having a cavity structure, and a support plate 2 provided inside the hot air box 1, and a plurality of electric heating tubes 3 provided inside the support plate 2.

[0026] A fan 4 is provided on one side of the hot air box 1, with the output end of the fan 4 facing the inside of the hot air box 1. A flow port 5 is provided on the other side of the hot air box 1. Hot air from the hot air box 1 is output to the drying oven through the flow port 5 via the fan 4 to dry the sample.

[0027] This technical solution involves placing the sample inside a drying oven, where heat is provided by the electric heating tube 3 of the hot air box 1, and the hot air is conducted to the flow port 5 by the fan 4 to dry the sample. The heat is fully distributed inside the drying oven, which can quickly raise the temperature inside the drying oven. This not only increases the drying temperature inside the drying oven, but also ensures uniform heat distribution, resulting in good drying effect for the sample. All parts of the sample can be fully dried with uniform heat distribution, shortening the drying time and improving the drying efficiency.

[0028] In addition, the drying oven is equipped with a storage component, and the sample is placed on the storage component.

[0029] In addition, a loading plate 6 is provided on one side of the fan 4.

[0030] In this technical solution, the loading plate 6 can assemble and fix the fan 4, thereby improving the stability of equipment operation.

[0031] In addition, the electric heating tube 3 has a U-shaped structure, and there is a gap between adjacent electric heating tubes 3.

[0032] Specifically, several sets of U-shaped electric heating tubes 3 can quickly raise the temperature inside the hot air box 1, thereby working with the fan 4 to conduct hot air to the flow port 5 and then to the drying oven to dry the sample.

[0033] In addition, the top of the hot air box 1 is equipped with a removable cover 7.

[0034] Specifically, the removable cover 7 allows for the removal of the loading plate 6 and facilitates the maintenance of the electric heating element 3.

[0035] Among them, the flow port 5 is located between the drying box and the hot air box 1.

[0036] In addition, in application, for the above-mentioned flow port 5, which is located on one side of the drying chamber, a guide plate can be set to guide the hot air output by the fan 4, thereby improving the uniformity of heat distribution in the drying chamber.

[0037] In summary, by means of the above-mentioned technical solution of this utility model, the following effects can be achieved: the sample is placed in the drying oven, and heat is provided by the electric heating tube 3 of the hot air box 1 and the hot air is conducted to the flow port 5 by the fan 4 to dry the sample. The heat is fully distributed in the drying oven, which can quickly increase the temperature in the drying oven. This not only increases the drying temperature in the drying oven, but also makes the heat distribution uniform, resulting in a good drying effect on the sample. All parts of the sample can be fully dried and the heat distribution is uniform, which shortens the drying time and improves the drying efficiency.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
