Description

Novel powder body classification device Technical Field The utility model belongs to the technical field of powder classification, and particularly relates to a novel powder classification device. Background In modern production of traditional Chinese medicines, crushing of medicinal materials is an important process component, and crushing treatment is carried out before the use of the traditional Chinese medicines, so that the traditional Chinese medicines are beneficial to exerting the property of the traditional Chinese medicines to the greatest extent, and the classification of the crushed powder of the medicinal materials is also a key link for influencing the quality and the efficacy of the preparation. The existing traditional screening technology realizes particle size separation through a mechanical screen, and when medicinal materials with different particle sizes are screened, screens with different apertures are required to be replaced usually, and the overall practicability is not high due to frequent replacement. Disclosure of Invention The utility model provides a novel powder grading device, which aims to solve the problems that the prior traditional screening technology realizes particle size separation through a mechanical screen, and when medicinal materials with different particle sizes are screened, screens with different pore diameters are usually required to be replaced, and the whole practicability is not high due to frequent replacement. The embodiment of the utility model provides a novel powder grading device, which comprises a support, wherein a screening barrel is arranged on the support, an air outlet box is arranged on the screening barrel, a driving mechanism is arranged on the air outlet box and in the air outlet box, a feeding partition plate is further arranged in the air outlet box, a feeding port is formed in the feeding partition plate in an upward extending mode, a screening mechanism is further arranged at the lower end of the driving mechanism, a flow guiding mechanism is arranged in the screening barrel, and a discharging port is formed in the lower end of the screening barrel. Further, one side of the air outlet box is provided with an air outlet, the bottom of the air outlet box is in a frustum shape with a narrow bottom and a wide top, the bottom of the air outlet box is in contact with the peripheral side wall surface of the feeding partition plate, and the bottom of the air outlet box is provided with an upward conical air inlet.
