Abstract

The utility model relates to the PET material drying equipment in the production process of chemical fiber industry, in particular to a device which uses hot air to pre-dry and dehumidify the raw materials; the raw material heat exchange pre-drying device comprises a machine frame, an external heating cylinder body and an internal drying liner; the external heating cylinder body is fixedly arranged on the machine rack; an air inlet and an air outlet are arranged on the external heating cylinder body; the internal drying liner is arranged inside the external heating cylinder body and comprises a feed inlet and a material outlet; an auger is arranged inside the internal drying liner; a plurality of hot air hoods and dehumidification hoods are arranged above the internal drying liner; the hot air hoods are connected with a hot air port; the dehumidification hoods are connected with dehumidification ports. The utility model well solves the problems of low heat exchange efficiency, long vacuumization time, small capacity and relatively high energy consumption in using a rotary drum for vacuumization and dehumidification, and is economic and practical and has good effect. The drying dehumidification time of the device is reduced by more than 30% compared with that of the rotary drum; the one-time raw material dehumidification amount of the device is increased by more than 35% compared with that of the rotary drum so as to greatly increase the productivity.

Description

Raw material heat exchange pre-drying device
Technical field
The utility model relates to the drying equipment of PET raw material in the chemical fibre industry production process, relates in particular to a kind of device that utilizes hot blast raw material to be carried out predrying dehumidifying.
Background technology
In the production process of chemical fibre industry, all be to vacuumize dehumidifying with rotary drum earlier at present for the PET raw material, the production that feeds intake then.But find that in daily use rotary drum has following deficiency: 1, heat exchanger effectiveness is low, and the pumpdown time is long, the raw material supply that influence is produced.2, each rotary drum finite capacity is measured lessly, is difficult to satisfy the production demand sometimes.3, use rotary drum need build relevant capital construction infrastructure, and because the capacity and the efficiency of rotary drum, therefore need reach some could satisfy production, the manpower and materials of waste billow.4, quantity is many, and auxiliary facility is many, the energy consumption height.
Summary of the invention
In order to solve above technical barrier, the purpose of this utility model provides a kind of practicality, good, the disposable processing material quantity of effect on moisture extraction is big and the raw material heat exchange pre-drying device of processing time period weak point.
In order to realize that above-mentioned purpose the utility model adopts following technical scheme:
Raw material heat exchange pre-drying device, comprise frame, heat cylindrical shell and inner drying courage outward, outer heating cylindrical shell is fixedly installed on the frame, it is provided with air inlet and air outlet, and described inner drying courage is arranged in the outer heating cylindrical shell, and the inner drying courage comprises charging aperture and discharging opening, and in the inner drying courage, be provided with auger, the top of inner drying courage is provided with some air bells caps and hydrofuge cover, and air bells cap connects hot-air mouth, and the hydrofuge cover connects moisture exhausting port.
As preferably, above-mentioned air bells cap and hydrofuge cover are spaced, and are fixed by the channel-section steel support that is arranged in the inner drying courage.By above-mentioned structure, compact conformation, air intake and effect on moisture extraction are better.
As preferably, above-mentioned inner drying courage is fixedly installed in the outer heating cylindrical shell by some round steel.By above-mentioned structure, make inner drying courage and outer heating tube structure compactness.
As preferably, above-mentioned outer heating barrel outer surface covers and is provided with heat-preservation cotton, forms attemperator, prevents that heat runs off.
As preferably, above-mentioned air inlet connects the boiler waste gas system.Preheat by boiler waste gas, make full use of the energy, reach the effect of economizing on energy.
The effect of above-mentioned utility model critical piece is as described below:
1. enter high-temperature hot-air by air inlet, the raw material in the internal dry courage of outer heating zone carries out external heat.
2. enter high-temperature hot-air by adding air bells cap, the raw material in the inner drying courage is directly carried out the high temperature dehumidifying.
3. the water vapour after by the hydrofuge cover raw material high temperature being heated is got rid of, and reaches effect on moisture extraction.
4. by auger raw material is evenly stirred in heating, raw material is fully heated and dehumidify.
Above-mentioned utility model well solved used in the past rotary drum vacuumize the dehumidifying heat exchanger effectiveness low, the pumpdown time is long, capacity is little, and the more high relatively many disadvantageous problems of energy consumption.Have economical and practically, good effectiveness the more important thing is that the desiccant dehumidification time ratio rotary drum of this device is few more than 30%, but the amount of disposable raw material dehumidifying but but Duos more than 35% than rotary drum, has improved production efficiency greatly.
