Description

Technical Field

[0001] The utility model belongs to the field of vibrating screens, and in particular relates to a vibrating screen for pharmaceutical use. Background Art

[0002] Vibrating screen equipment is commonly used in pharmaceutical processes for the sorting and processing of powder and granular materials. The existing vibrating screen is mainly composed of a screen body and a vibrating device. The material is loaded onto the screen of the screen body. Under the effect of the vibration generated by the vibrating device, the material with a particle size smaller than the aperture of the screen is screened downward, and the material with a particle size larger than the aperture of the screen is retained above the screen, thus achieving material screening. In actual operation, it was found that due to the size of the site space, the type of material and other processing conditions, the existing vibrating screen cannot be relatively adjusted between the screen body located above and the base located below, which has a certain impact on the screening process and limits its scope of application.

[0003] Announcement No. CN206464228U records a pharmaceutical vibrating screen device, which includes a base, an outer sleeve is fixedly installed at the top center of the base, and two left and right base devices are installed on the outer wall of the outer sleeve; the base device includes a wheel bracket welded and fixed to the outer sleeve, an upper pressure wheel, a lower support wheel and a side pressure wheel are installed on the wheel bracket, a track is provided between the upper pressure wheel, the lower support wheel and the side pressure wheel of each base device, a support plate is installed on the outer side of each track, a guide column is fixedly installed on the support plate, and a spring is sleeved on the guide column; it also includes a screen body device, the screen body device includes a bottom plate, a barrel is provided at the top center of the bottom plate, an inner sleeve is provided at the bottom center, a vibration motor is installed on the inner wall of the inner sleeve, a feed port is provided at the top of the barrel, a screen is provided in the middle of the inner cavity of the barrel, and a conical blanking plate is provided in the middle and lower part of the inner cavity of the barrel; a connecting hole is opened at the edge of the bottom plate, and the upper ends of the two guide columns are respectively located in the connecting hole and locked with a lock nut.
