Abstract
The utility model discloses a kind of roller drying heated air circulation devices, including roller drying machine, heat exchanger and circulating fan, backwind tube is provided between the heat exchanger and circulating fan, moisture absorption barrier is provided in the backwind tube, quick lime layer is provided in the moisture absorption barrier.Compared with prior art, the utility model is by setting moisture absorption barrier, using the water suction heat dissipation effect of quick lime by the water vapor absorption in circulating air, avoids the generation of Moisture Regain in follow-up drying course.
Description
Technical field
The utility model belongs to drying equipment technical field, more particularly to a kind of roller drying hot air circulation dress
It puts.
Background technology
Roller drying machine (rattler-drying machinery) is one of traditional drying equipment, and equipment operation is reliable,
Operating flexibility is big, adaptable, processing capacity is big, is widely used in metallurgy, building materials, chemical industry, coal washing, chemical fertilizer, ore, sand, viscous
The fields such as soil, kaolin, sugar.
Roller drying machine in the prior art is typically equipped with heated air circulation device, to reduce energy consumption.It is usually wrapped
It includes the heat exchanger of connection roller drying machine and has made used hot wind from roller drying machine absorption, and the hot wind is led to back and is changed
Circulating fan in hot device.But since hot wind is to that can carry part vapor after drying materials, and vapor is returned with heat
Wind circulation continuous increases, so that there is Moisture Regain in subsequent drying course, reduces drying efficiency and dries quantity.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of roller drying hot wind that can reduce Moisture Regain
Circulator.
To achieve the above object, the utility model provides following technical solution：A kind of roller drying heated air circulation device,
Including roller drying machine, heat exchanger and circulating fan, backwind tube, the return air are provided between the heat exchanger and circulating fan
Moisture absorption barrier is provided in pipe, quick lime layer is provided in the moisture absorption barrier.
Through the above technical solutions, setting moisture absorption barrier in backwind tube, the quick lime layer in moisture absorption barrier can be utilized
Vapor between absorption cycle hot wind, so as to reduce the appearance of Moisture Regain in follow-up drying course；And due to quick lime
Water suction has heating effect, also can compensate for circulating air dispersed heat in Xun Huan, ensures the circulating effect of circulating air.
It is further arranged to, the moisture absorption barrier includes supporting rack, and at least two layers of Moisture absorption cloth is coated on support frame as described above
Layer, the quick lime layer are arranged between moisture absorption layer of cloth.
Through the above technical solutions, since circulating air flow velocity is very fast, moisture absorption layer of cloth can be kept right using supporting rack
Stability during circulating air moisture absorption.
It is further arranged to, a plurality of horizontally disposed clamping strip is provided on the moisture absorption layer of cloth.
Through the above technical solutions, the setting of clamping strip, when enabling to moisture absorption barrier in backwind tube, Neng Goubao
The uniform shape of quick lime is held, avoids hanging down in lowermost end due to gravity influence, ensure that moisture absorption barrier imitates the moisture absorption of circulating air
Rate and moisture absorption quality.
It is further arranged to, sets fluted on the outer wall of support frame as described above, retainer plate is embedded in the groove, it is described
Moisture absorption layer of cloth is arranged between retainer plate and supporting rack.
Through the above technical solutions, since quick lime heat absorption is irreversible, moisture absorption layer of cloth is fixed on by groove by retainer plate
On, the timely replacement to quick lime layer can be facilitated, ensure the moisture absorption quality to circulating air.
It is further arranged to, opening is provided on the backwind tube, the moisture absorption barrier is plugged in opening.
Through the above technical solutions, the setting of opening can facilitate the installation and replacement of moisture absorption barrier, it is conveniently operated.
It is further arranged to, the one side of opposed open is provided with limited block in the backwind tube, and the moisture absorption barrier contradicts
On limited block.
Through the above technical solutions, the setting of limited block enables to moisture absorption barrier that can be against after installing on limited block,
Moisture absorption barrier is avoided to tilt, ensures moisture sorption effect.
Compared with prior art, the utility model, will using the water suction heat dissipation effect of quick lime by setting moisture absorption barrier
Water vapor absorption in circulating air avoids the generation of Moisture Regain in follow-up drying course.

Specific embodiment
The technical solution of the utility model and advantageous effect are understood for convenience of those skilled in the art, with reference to attached drawing
Specific embodiment is made described below.
A kind of roller drying heated air circulation device, including roller drying machine 1, heat exchanger 2 and circulating fan 3, heat exchanger 2 with
Backwind tube 4 is provided between circulating fan 3, is provided with an opening 12 on backwind tube 4, in opening 12 grafting be provided with moisture absorption barrier
5, to the vapor removal that will be carried in circulating air.
Moisture absorption barrier 5 includes a supporting rack 7, and 7 lateral wall of supporting rack sets fluted 10, the groove 10 on supporting rack 7
Retainer plate 11 annular in shape is inside arranged with, two layers of moisture absorption layer of cloth 8, moisture absorption layer of cloth 8 are fixed between the retainer plate 11 and groove 10
Between be provided with quick lime layer 6, absorption to the vapor in circulating air is realized by absorb water exothermic performance of quick lime, together
When quick lime water suction liberated heat can also compensate due to return air process dispersed heat.
A plurality of horizontally disposed clamping strip 9 is provided on moisture absorption layer of cloth 8 so that quick lime can uniformly dispersing inhaling
In wet barrier 5, so as to keep moisture absorption efficiency and moisture absorption quality..
