A drying and screening device for shaped particles

Abstract

The invention discloses a drying and screening device of formed particles. The drying and screening device comprises a feed funnel, a dehumidification drying mechanism, a centrifugal screening mechanism and a discharge mechanism connected in sequence; the dehumidification drying mechanism has a dehumidification drying chamber communicated with the bottom of the feed funnel, an air scattering plate and a high-temperature air heater; the air scattering plate and the high-temperature air heater are oppositely arranged on two sides of the dehumidification drying chamber; the centrifugal screening mechanism has a centrifugal screen tightly communicated with the bottom of the dehumidification drying chamber, a rotating module for driving the centrifugal screen to rotate and a wet pumping module communicated with the centrifugal screen; and the discharge mechanism has a thick discharge inner through pipe and a thin discharge inner through pipe communicated with the bottom of the centrifugal screen. The drying and screening device of the formed particles integrates discharge, dehumidification, drying and screening as a whole to preferably realize automatic treatment of discharge, dehumidification, drying and screening.

Description

technical field [0001] The invention relates to the technical field of treatment after molding of general granular materials, in particular to a drying and screening device for shaped particles. Background technique [0002] At present, the post-processing device for particle forming in the industry generally adopts the conveyor belt method on the discharge, which has special properties to add water flow to assist in transportation, and the drying method is mostly used for fluidized bed drying. The screening of granular materials still uses the traditional method. Vibrating sieve screening method and older manual screening, such as the Chinese patent "A discharge device on a screening device (patent application number is 201420226848.1)" proposes a discharge device on a screening device, which is only an independent screening The process of discharging material in the equipment. [0003] At present, the drying forms of drying equipment in the market are diversified. The hot...

Problems solved by technology

[0003] At present, the drying forms of drying equipment in the market are diversified. The hot air circulation system is more commonly used. There are certain technical differences in the equipment, and the fluidized drying bed is the most common; Movement to achieve the purpose of screening; there are also a small number of equipment that connect the two processes of screening and drying to a set of processing equipment, but lack of control system, it is difficult to realize the automatic processing of discharging, dehumidification, drying and screening

These devices have good practical effects in certain limited fields, but they are not suitable for the production environment of today's intelligent integration of technology and industry.
