Description

Technical Field

[0001] This invention belongs to the field of soil and water testing technology, and provides a soil moisturizing device and method based on ultrasonic micro-mist diffusion. Background Technology

[0002] With the increasing frequency of extreme rainfall events globally, loess disasters have seriously threatened food security, geological safety, and human settlement safety. Accurate measurement of the hydrodynamic parameters of loess samples at different moisture contents can help improve the accuracy of early identification of disaster sites and reveal the inducing mechanisms of soil and water disasters.

[0003] Currently, methods for preparing loess samples with different water content usually involve small peristaltic pumps, manual water spraying with a kettle, or dripping water with a medical syringe. These methods have drawbacks such as being cumbersome to operate, easily damaging the samples, and making it difficult to accurately control the water content of the samples. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a soil humidification device and method based on ultrasonic micro-mist diffusion, which is simple to operate, does not damage the sample, and can accurately control the moisture content.

[0005] The technical solution of the present invention includes a water tank, a spray component, a rotating component, a pressure sensor, and a controller.

[0006] The spraying component includes a spray chamber and a sprayer. The sprayer is fixed to the inner wall of the spray chamber and connected to a water tank. The sprayer atomizes the water. A rotating component is located inside the spray chamber and drives the loess sample to rotate.

[0007] The pressure sensor is located at the top of the rotating component and is used to detect the pressure of the loess sample.

[0008] The controller is communicatively connected to the sprayer, the rotating component, and the pressure sensor. The controller controls the rotation speed of the rotating component, the spray rate of the sprayer, and whether the sprayer and the rotating component work based on the pressure detected by the pressure sensor.

[0009] Furthermore, there are several sprayers, evenly distributed on the inner wall of the spray chamber.

[0010] Furthermore, the rotating component includes a cylinder, a motor, a chassis, and a loading tray; the chassis is fixed to the bottom of the sealed chamber, the cylinder is fixed on the chassis, and the bottom of the cylinder is sealed to the chassis; the motor is located inside the cylinder, the output shaft of the motor is connected to the loading tray, driving the loading tray to rotate; the loading tray is sealed to the upper end of the cylinder; and the motor is communicatively connected to the controller.

[0011] Furthermore, the upper end of the rotating component is equipped with permeable stones, and the loess sample is placed on the permeable stones.

[0012] Furthermore, filter paper was laid on the permeable stone, and the loess sample was placed on the filter paper.

[0013] Furthermore, the spray chamber is equipped with a drainage component, which includes a water level sensor and a water pump. The water level sensor is used to detect the water level in the spray chamber, and the output end of the water pump is connected to the water tank through a pipe. The water pump is used to discharge the water in the spray chamber into the water tank. Both the water level sensor and the water pump are connected to the controller.

[0014] Furthermore, the spray chamber includes a housing and a lid, with the lid sealingly fitting onto the housing.

[0015] This invention also provides a method for soil moistening based on ultrasonic micro-mist diffusion, characterized by comprising the following steps: Loess samples were taken and divided into loess sample A and loess sample B. The moisture content of loess sample A was calculated by drying method, and the moisture content of loess sample B was obtained. Then the moisture mass and dry loess mass of loess sample B were calculated. The water content of the target loess sample is calculated based on the required moisture content, thereby calculating the total mass of the target loess sample and the pressure generated by the target loess sample. Loess sample B is placed on the rotating component. The controller controls the rotating component to rotate the loess sample B, while the sprayer atomizes the water, so that the loess sample B absorbs the water in the spray chamber evenly and gradually increases in weight. When the pressure sensor detects that the pressure generated by loess sample B is greater than or equal to the pressure generated by the target loess sample, the controller controls the rotating parts and sprayer to stop working and remove loess sample B.

[0016] The technical solution provided by the embodiments of the present invention has the following advantages compared with the prior art: A loess sample is taken and divided into two equal parts, loess sample A and loess sample B. The moisture content of loess sample A is calculated using an oven-drying method, thus obtaining the moisture content of loess sample B. The water mass and dry loess mass of loess sample B are then calculated. Based on the desired target loess sample moisture content, the water mass of the target loess sample is calculated, thus determining the total mass of the target loess sample and the pressure generated by it. Loess sample B is placed on a rotating component. The controller controls the rotating component to rotate loess sample B, while simultaneously controlling a sprayer to atomize water, allowing loess sample B to uniformly absorb moisture in the spray chamber and gradually increase in weight. When the pressure sensor detects that the pressure generated by loess sample B is greater than or equal to the pressure generated by the target loess sample, the controller stops the rotating component and the sprayer, and loess sample B is removed. This loess sample B is the loess sample with the desired target moisture content. Compared to existing technologies, this invention is simple to operate, does not damage the sample, and can accurately control the moisture content.

[0030] In the embodiments provided by the present invention, there are several sprayers 3, which are evenly distributed on the inner wall of the spray chamber to ensure that the water mist in the spray chamber is evenly distributed and to avoid the loess sample absorbing water evenly.

Loess sample B is placed on the rotating component. The controller controls the rotating component to rotate the loess sample B, while the sprayer 3 atomizes the water, so that the loess sample B absorbs the water in the spray chamber evenly and gradually increases in weight. When the pressure sensor 5 detects that the pressure generated by loess sample B is greater than or equal to the pressure generated by the target loess sample, the controller controls the rotating part and sprayer 3 to stop working and remove loess sample B.

[0039] Specifically, the moisture content of loess sample A is measured using methods such as the combustion method and the drying method, according to geotechnical testing standards. Then, the mass of water in loess sample B is calculated. in: : Moisture content in loess sample B under initial conditions (unit: kg).
