Description

Technical Field

[0001] This invention belongs to the field of air drying equipment, and specifically relates to an air drying device for laboratory use. Background Technology

[0002] During the experiment, all soil samples collected before testing needed to be air-dried, ground, and sieved for analysis. Current technology, when conducting multi-sample, multi-factor studies, requires each sample to be placed on a sheet of kraft paper for natural air drying. This results in a large drying area being needed for a large number of soil samples, making it impossible to control the drying conditions. Furthermore, the lack of independent separation between samples leads to cross-contamination and affects the test results.

[0003] Various experimental bottles are needed during the experiment, and they need to be cleaned frequently. With current technology, the experimental bottles are placed on racks to air dry after washing, which is a slow drying process and delays the experiment. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a laboratory air-drying device, which has the advantages of being able to air-dry multiple soil samples at one time, occupying little space, avoiding cross-contamination of soil samples, and having adjustable and controllable air-drying conditions. The present invention can also be used for air-drying laboratory experimental bottles.

[0005] A laboratory air-drying device includes a chamber, the chamber comprising a bottom plate, side plates on both sides of the chamber, a plurality of exhaust fans on the bottom plate, a plurality of ventilation holes on the side plates of the chamber, and the interior of the chamber consisting of a plurality of drying layers.

[0006] The drying layer has side panels on both sides of the box. Several partitions are fixedly installed in the drying layer to divide the drying layer into several functional chambers. The functional chambers are a negative pressure chamber in the middle and sample placement chambers on both sides of the negative pressure chamber. The bottom plate of the negative pressure chamber is the bottom plate of the box. An exhaust fan is installed at the bottom plate of the negative pressure chamber. The space inside the negative pressure chamber is composed of the front plate, the bottom plate and the partitions on both sides of the negative pressure chamber.

[0007] The partition layer consists of a left plate, a middle plate, and a right plate. Each of the left, middle, and right plates has multiple corresponding and interconnected ventilation holes. The middle plate is slidably connected back and forth. The airflow in the sample placement chamber is adjusted by regulating the alignment of the ventilation holes on the middle plate with those on the left and right plates.

[0008] Furthermore, it also includes a sample placement box placed in the sample placement chamber, wherein multiple sample placement boxes can be arranged in the sample placement chamber.

[0009] Furthermore, the sample placement box assembly consists of two trapezoidal boxes. Each trapezoidal box has a trapezoidal structure with a rounded bottom at the opening. A humidity sensor is installed on the inner wall of each trapezoidal box. The two trapezoidal boxes, facing each other, form a square sample placement box placed inside the sample placement chamber. The sides of each trapezoidal box have graduations for measuring soil sample volume, and the front has a label slot for placing sample labels.

[0010] Furthermore, the sample placement box is a square box that can hold experimental bottles.

[0011] The front panel of the negative pressure chamber is equipped with a display and control screen, which is connected to the humidity sensor and the exhaust fan circuit. It can monitor the humidity of the air-dried sample in real time, and intelligently adjust the fan speed based on the real-time humidity feedback from the humidity sensor. At the same time, the target humidity of the soil sample can be preset through the display and control screen, and a reminder can be given through the display and control screen and information push when the humidity reaches the preset humidity.

[0012] It also includes a box door, which is connected to the box body by a hinge. When the box door is closed, the box door and several sample placement chambers in the vertical direction form the internal space of several sample placement chambers.

[0013] The method of using this invention is as follows: Take a certain amount of soil sample using the sample placement box as needed, place it in different sample placement chambers, close the box door, turn on the exhaust fan, adjust the alignment of the ventilation holes on the ventilation plate with the ventilation holes on the left and right plates, control the wind speed. In addition to manual adjustment, the wind speed can also be intelligently adjusted by the real-time humidity feedback from the humidity sensor. Start the exhaust to dry the sample, observe the control display, and when the humidity of the sample placement box reaches the experimental testing requirements, it can be taken out for testing.

[0014] The beneficial effects of this invention are: 1) It has several drying layers, each with several sample placement chambers and several sample placement boxes, allowing for the simultaneous drying of experimental soils with different drying requirements. Soil samples are placed independently in their respective placement boxes, preventing cross-contamination. The trapezoidal design and arc-shaped structure at the narrow opening of the sample placement boxes ensure the drying effect within a limited space, while the arc-shaped structure facilitates convenient collection of the dried soil. 2) This invention can dry multiple samples at once. The exhaust fan and vertical multi-chamber design save space compared to existing technologies where samples are placed in a larger drying area for natural drying. 1) Saves time and is highly efficient; 2) The scale and humidity sensor settings of the sample placement box make the control of the sample during the experiment more precise, greatly increasing the accuracy of the later detection; 3) The two sample placement boxes form a square structure and are placed in the sample placement chamber. The sample placement chamber can be set with multiple layers of sample boxes, making great use of the internal space of the sample placement chamber; 4) The design of the ventilation holes on the ventilation plate and the ventilation holes on the left and right plates can control the air volume during the sample drying process, thereby controlling its drying time. The fan speed can also be intelligently adjusted by detecting and feeding back the humidity through the humidity sensor to meet the drying requirements of different types of soil.
