Soil sample humidifying and dehumidifying device

Abstract

The invention discloses a soil sample humidifying and dehumidifying device. The soil sample humidifying and dehumidifying device comprises a top plate and a bottom plate which are parallel to each other and are arranged up and down; the top plate and the bottom plate are connected through a plurality of vertical columns; the lower part of the top plate is connected with a humidifying chamber through a transmission device, and the humidifying chamber is connected with a liquid storage tank through a first pipeline; the first pipeline is also sequentially and horizontally connected with a liquidgasification atomization device and an air supply device; the liquid gasification atomization device and the air supply device are electrically connected with a gasification humidifying controller separately; a vacuum chamber is arranged on the bottom plate, and the vacuum chamber is connected with a gas-water dual-purpose vacuum pump through a second pipeline; the gas-water dual-purpose vacuum pump is electrically connected with a pressure reduction controller; and the vacuum chamber is connected with the humidifying chamber through a sealing round plate. According to the device, when the soil sample is subjected to humidifying and dehumidifying, the soil sample can be humidified and dehumidified quickly and uniformly through pressure difference and the atomized gasified water; and a batch of soil samples also can be humidified and dehumidified according to the number of holes in the prepared sealing round plate.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering equipment, and in particular relates to a soil sample humidification and dehumidification device. Background technique [0002] In indoor soil engineering experiments, when cutting original soil samples (undisturbed soil samples) or preparing reshaped soil samples (disturbed soil samples), change the moisture content of the original soil samples or reshaped soil samples to obtain soil samples with ideal moisture content It is an important part of soil engineering experiment. [0003] After the original state or reshaped soil sample is prepared, its water content needs to be changed. The traditional humidification methods include pre-wet method and burying method. It is impossible to humidify in batches, and it needs to be processed individually, which requires a lot of work. The burial method can increase the humidity in batches, but the humidification time is too long, and the ...
