The application discloses a plant composition with soothing effect and a preparation method and application thereof, and the composition comprises saponins extracted from radix cynanchi rossii and radix anemarrhenae, and polysaccharides extracted from the radix anemarrhenae, and the mass ratio of the saponins to the polysaccharides is (1-5):(1-3). The technical scheme of the application is as follows: the radix cynanchi rossii and the radix anemarrhenae are mixed in a certain proportion, crushed, extracted by an alcohol solution, and then saponins are obtained through composite membrane separation; the remaining residues are extracted by water, impurities are removed by a clarifying agent, and the radix anemarrhena polysaccharides are obtained through ultrafiltration; and the saponins and the polysaccharides are compounded in a certain proportion, supplemented by polyhydric alcohol to be dissolved, so that the composition with the soothing effect is obtained, and the composition can be applied to the preparation of skin care cosmetics, especially soothing and anti-irritation products.

The utility model discloses a dust treatment device of a bulk material conveying system, which relates to the technical field of dust treatment devices and comprises a material conveying belt, side plates are fixedly mounted on two sides of the material conveying belt, a top plate is fixedly mounted at the tops of the side plates, and a dust hood is fixedly mounted at the bottom of the top plate. A dust suction port is formed in the bottom of the dust suction cover, two impeller fans are installed on the top of the top plate and communicate with the interior of the dust suction port, a conveying pipe is fixedly installed at the output ends of the impeller fans, and a water tank is arranged below the material conveying belt. The dust collection device has the beneficial effects that through the arrangement of the dust collection cover, the dust collection opening, the impeller fan, the conveying pipe, the water tank, the treatment box, the collection drawing box, the filter cloth, the water distribution plate, the nozzle, the water pump, the water guide pipe and the water pumping pipe, dust generated during material conveying can be collected, sprayed and subjected to dust falling treatment; therefore, the situation that operators and the environment are injured by flying dust is avoided.
