High-viscosity rapid drying machine

Abstract

The invention discloses a high-viscosity rapid drying machine which comprises a vertical dryer main body provided with an inner shell and a main shaft. The high-viscosity rapid drying machine is characterized in that a string of geared flywheels are fixedly arranged on the main shaft at intervals along an axial direction; and turbine fans are arranged at intervals above the geared flywheels and used for moderate-temperature drying and high-temperature drying. According to the high-viscosity rapid drying machine, the drying evaporating area is increased through action between the mechanical geared flywheels arranged on the main shaft and a material; and the high-efficiency heat transfer and mass transfer purpose can be realized through vortex generated by the geared flywheel and turbine fan structure. The high-viscosity rapid drying machine has the advantages of high safety performance, low energy consumption, no need of backmixing, extremely high equipment efficiency, compact structure, low operating cost, less system equipment, small occupied area, less investment, continuous operating effect and rapidness in drying, is applicable to various materials with different viscosity and humidity, is suitable for drying various high-viscosity high-humidity materials, can be widely applied to the fields such as printing and dyeing, chemical industry, medicines, municipal administration, cultivation, petrochemical industry and the like and can be used for drying thermosensitive materials.

Description

technical field [0001] The invention relates to a drying equipment for special materials, in particular to a fast drying machine for high-viscosity materials. Background technique [0002] Drying high-moisture and high-viscosity materials has always been a difficult point in the drying industry. These materials are non-Newtonian liquid materials, some are softened solids, some are semi-fluid, and basically cannot be transported by positive displacement pumps; some materials are slurry Thin or paste-like, high humidity makes it difficult to extrude and granulate (it cannot be granulated, and it sticks together after extrusion), and it is difficult to form. [0003] The commonly used drying room drying method has low efficiency; mixing paddle drying has sticky materials around the axis, the bond is firm and difficult to clean, and when the material is dried to a critical point, the drying efficiency is lower and the paddles are easy to entangle, making the equipment lose its o...

AI Technical Summary

Problems solved by technology

[0006] To sum up, it can be seen that many high-moisture and high-viscosity materials are often dried in a drying room at present. Drum dryers can only dry high-viscosity and high-humidity materials that have a better cloth film and are easy to clean after drying. If the final moisture content of the dried product is relatively low At this time, the efficiency of this kind of dryer is extremely low or it is not suitable for use; the stirring dryer can only dry medium-viscosity and high-humidity materials, and it is powerless for materials like "rubber bands" that appear during drying. The quality is poor; the fluidized bed can only be used in several typical high-viscosity products, such as amide, potassium acrylate, etc., and it cannot dry nearly liquid high-viscosity and high-humidity materials at all

The existing drying equipment still has the disadvantages of bulky size, uneven moisture content of dried products, poor product quality, incapable of continuous production but intermittent production, and high labor intensity of workers.
