Embodiment
The utility model will be further described with specific embodiment below in conjunction with the accompanying drawings.
The utility model provides a kind of drying process device handled for sludge reduction.Fig. 1 and Fig. 2 are shown respectively
The structural representation and drying of highly effective sludge drying process device of the present utility model along A-A to sectional view.Such as Fig. 1 and
Shown in Fig. 2, highly effective sludge drying process device of the present utility model includes：Cast hopper 1, is provided with agitating paddle；Material is conveyed
Machine 8, its two ends are connected sludge being delivered in drying machine main body with cast hopper 1 and drying machine main body respectively；Dry owner
Body, it includes drying 3 and the air outlet being connected with drying 5 and material outlet 7；Wherein, it is provided with and stirs in drying 3
Mix and stirring vane 9 is connected with axle 6, agitating shaft, and be intervally distributed with the inwall of drying lift blade 4.In drying
Cylinder 3 is provided with the hot-air mouth 2 being connected with heat blower (not shown) close to the end of material conveyor 8, with from hot blast
Hot blast is received in generator.
When carrying out the drying process of sludge, sludge in sludge-tank first via sludge pump enter the folded spiral shell machine of dehydration or
Plate and frame filter press carries out preliminary hydro-extraction, tentatively reduces moisture percentage in sewage sludge, and then dehydrated sludge cake enters cast hopper wait and further done
It is dry.In cast hopper, agitating paddle is stirred broken to sludge first.The hot blast that heat blower operation is produced enters drying machine
After main body, uniform temperature to be achieved, mud cake after crushing enters through material conveyor in the drying of drying machine main body, is set
The lift blade put in drying drives, and starts the do action from drying bottom to top.At the same time, by hot blast
In the presence of the hot blast that mouth is blown into, sludge is constantly dried and persistently crushed in the presence of stirring vane, becomes thin
Little particle, moisture content is further reduced.After continuous round action is carried out above, sludge average moisture is reduced, gradually to drying
Cylinder middle part is moved, after further crushing and drying surface area increase, the fluidised form of material flow formation waterfall shape, until
Sludge is discharged out of the furnace by material outlet.The drying sludge of output enters warehouse storage after helical feed.
It is worth noting that, in highly effective sludge drying process device of the present utility model, lift blade and stirring vane are
Revisable, it can carry out different adaptability designs according to different sludge shape, with reach optimal drying efficiency and
Economy.
In highly effective sludge drying process device of the present utility model, the material conveyor is preferably double-shaft spiral conveying
Machine, make it that helical axis can be stirred broken, raising drying efficiency to sludge again during conveying.
In highly effective sludge drying process device of the present utility model, the drying is preferably rotatable.This practicality is new
Operating can produce one while the comminuting dasher of the drying process device of type and rotatable both devices of dry cylinder
The effect for plus one more than two so that the overall heat-transfer coefficient of the present apparatus reaches common more than 2-3 times.The raising of drying efficiency, makes
Treating capacity in the unit interval is obtained to increase.
In highly effective sludge drying process device of the present utility model, as shown in Fig. 2 the agitating shaft is to deviate drying
What central axis was set.Such a setting can improve the crushing effect of sludge, while reducing the probability that stirring vane breaks down.
In highly effective sludge drying process device of the present utility model, the air outlet passes through circulating fan (not shown)
It is connected with heat blower.Preferably, it is provided with deduster between the air outlet and circulating fan.Deduster is used for collecting
The mud granule flown out with hot blast, the hot blast for discharging drying is purified.Then the hot blast after the purification is through circulating fan
It is delivered to heat blower so that hot gas can be recycled, further saves fuel, reduces operating cost.
For the hot blast temperature discharged through air outlet as the change of evaporation capacity has the situation of reaction at once, this practicality is newly
The highly effective sludge drying process device of type employs corresponding control device, and the drying process device is connected with PLC control cabinet,
So that change of the works with condition, corresponding countermeasure can be made at once, for example, the temperature of hot blast is discharged according to air outlet,
The firing rate in heat blower is adjusted in real time, so as to ensure that the hot blast temperature for being delivered to drying is consistent, so as to ensure that
The control and management of finished product water content.By setting the PLC control cabinet, operator can be carried out life using touching type operation disk
Production operation, can be achieved Automated condtrol and remote monitoring.When a failure occurs it, fault cues are had on touching type operation disk, side
Just maintenance personal is quickly repaired.
