Medicinal material screening device with good dedusting effect for biotechnology research and development

Abstract

The invention discloses a medicinal material screening device with a good dedusting effect for biotechnology research and development, and belongs to the field of biotechnology. The device comprises ascreening box, a protective top plate is arranged at the top end of the screening box, a feed hopper is arranged in the middle of the upper surface of the protective top plate, purification water tanks are arranged at the two ends of the screening box, a negative pressure fan is arranged at the top end of each purification water tank, limiting plates are arranged at the two ends of the upper surface of the protective top plate, the top ends of the limiting plates are movably connected with dust collection covers corresponding to the feed hopper, the top ends of the negative pressure fans areprovided with exhaust pipes corresponding to the dust collection covers, the bottom end of the screening box is provided with an impurity removing mechanism, the impurity removing mechanism comprisesa driving motor, the output end of the driving motor is provided with a transmission shaft, and a screening plate is arranged above the transmission shaft. The device is simple in structure, convenient to use, good in dust removing function and capable of effectively preventing a large amount of dust from flying out during use, so that use experience of a user on the screening device is improved.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a device for screening materials for biotechnology research and development with good dust removal effect. Background technique [0002] Chinese patent (publication No. CN209156409U) discloses a device for screening medicinal materials that can be used for biotechnology research and development, including a screening box. The upper side of the screening box is provided with an inverted V drug guiding platform. The screening box There are two symmetrically distributed water tanks on both sides near the inverted V drug guide platform, a drug discharge hopper is provided in the middle of the lower side of the screening box, and two symmetrically distributed vacuum cleaners are arranged on both sides of the screening box , The side of the screening box close to the vacuum cleaner is provided with an air collecting pipe, the dust suction port of the vacuum cleaner is connected...

AI Technical Summary

Problems solved by technology

[0004] However, due to the relatively simple structure of the screening device, the dust removal effect of the screening device is poor, and a large amount of dust is easily scattered during use, and the scattering of dust will affect the user's experience in using the screening device.
