Three-plasmid whole sealing environmentally friendly vibration fluidized bed dryer

Abstract

The invention relates to a three-plasmid whole sealing environmentally friendly vibration fluidized bed dryer which is suitable for drying powder material of regular shape such as Laroflex MP with granularity ranging from 50mu m to 5000mu m. The drier comprises a foundation (9), a lower housing (13), a fluidized bed body (6), an upper housing (18) and a bag type dust collector (24); wherein the lower housing (13) is supported on the foundation (9) by a slantly arranged plate spring (12), a case type vibration exciter (14) is arranged at the front end of the lower housing (13), the fluidized bed body (6) is arranged above the lower housing (13) and internally provided with a hood-shaped fluidized bed plate (7), the upper housing (18) is arranged above the fluidized bed body (6) and internally provided with a plurality of groups of bag type dust collectors (24). An air-reserve tank (24.6) is arranged outside the upper housing (18), a plurality of air branch pipes (24.3) are internally arranged in the air-reserve tank (24.6), wherein each air branch pipe (24.3) is provided with a pulse solenoid valve (24.5), the bottom part thereof is provided with an air source hole (24.7). The drier of the invention features low energy consumption, high production efficiency, good operation stability and good uniformity of products.

Description

(1) Technical field [0001] The invention relates to a fluidized bed dryer. It is suitable for drying regular-shaped powder materials with a particle size of 50-5000 μm, such as chloroether resin. It belongs to the technical field of drying equipment. (2) Background technology [0002] The product is chloroether resin, referred to as LMP. It is a white powder crystal polymer compound. A new product just developed in the early 21st century. During the production process, LMP is dried in an intermittent disc fluidized bed. Its main disadvantages are: [0003] 1. The disc fluidized bed is a fixed fluidized bed without a vibrating motor. Its material transportation, movement and fluidization all depend on the air volume. Therefore, the disc fluidized bed needs a large air volume and high energy consumption. [0004] 2. The disc fluidized bed is a single-pot intermittent production, and its feeding and discharging are all manual operations. Therefore, the labor intensity i...

AI Technical Summary

Problems solved by technology

Its material transportation, movement and fluidization all rely on the effect of air volume. Therefore, the disc fluidized bed needs a large air volume and high energy consumption.

[0004] 2. The disc fluidized bed is a single-pot intermittent production, and its feeding and discharging are all manual operations

Therefore, the operation stability is not good, the back-mixing phenomenon is serious, the product uniformity is poor, and the quality is difficult to guarantee
