Combined disk vibration drying screening machine

Abstract

The invention relates to a combined disk vibration drying screening machine, comprising a disk vibration dryer and a disk rotation vibration screening machine, wherein the disk rotation vibration screening machine is provided with a discharge hole along tangential direction, the disk dryer is coaxially fixed with the disk rotation vibration screening machine via a disk drying screening transitionsection, the disk rotation vibration screening machine is coaxially fixed by multiple layers of screening sections, screen meshes and pore plates are designed into shapes of upward protrusion in the middle and downward inclination at the periphery, a recycle awl realizes that materials are concentrated to central location in the process of falling from upper layer to lower layer; the circular motion of materials can be realized in dry section, and the circular motion and the radial motion of materials can be realized simultaneously at screening section. In the invention, disk vibration dryingand disk vibration screening are combined together organically and has compact integral structure, thereby saving transmission equipment between drying and screening, improving production efficiency,reducing equipment cost and saving energy.

Description

technical field [0001] The invention belongs to the field of mechanical engineering, in particular to a combined disc vibration drying and screening machine. Background technique [0002] At present, the drying and screening of materials are basically carried out separately, during which transmission equipment is used for material transmission, resulting in a relatively complex structure of the entire system, a large footprint, low production efficiency, and high manufacturing and operating costs. [0003] In recent years, many new vibrating dryers have appeared on the market. These vibrating dryers have many advantages: due to the vibration, the powder or granular materials in the air flow, which has the characteristics of agitating dryers, and can reduce the friction between particles, and the crystal form is complete. Uniform heating, low heat consumption. But its drying effect is general, thermal efficiency is low, equipment utilization rate is low, and production capac...

[0004] By searching, a patent document (name: combined rotary vibrating disc drying and screening machine, patent number: 88210481.0) of Northeast Pharmaceutical Factory was found. This patent document discloses a combined device similar to this patent application. The drying machine and the screening machine are combined together coaxially. There are multi-layer disks on the upper and lower sides of the drying machine. The drying machine disk in this patent is a spiral plate structure, which is relatively complicated to manufacture and the drying effect is general; the screening machine is a single-layer planar structure. Screening effect is average
