Description
Technical field
Drying equipment is the utility model is related to, more particularly to microwave sludge drier, belongs to sludge treatment device technology
Field.
Background technology
Dewatered sludge is the final product of municipal sewage plant, with urban wastewater discharge and treatment effeciency increasingly
Increase, its yield are also increasing.Sludge is made granulated fertilizer or adds chemical fertilizer simultaneously mixed fertilizer is made to enter to enter the market by drying
The method of field sale, can reach not only can conveniently, safely use but also can balance the purpose of sludge treatment expense.Sludge Composting
A kind of agricultural worldwide ideological trend for meeting waste reuse, it may be possible to final disposal selection preferentially used.Therefore, new height is developed
The drying sludge fertilizer technology of effect is that to solve sludge from wastewater treatment plant outlet difficult, promotes sludge reduction, loss of weight, harmless
Change, one of the important channel of recycling.
Heated drying sewage sludge is a kind of straightforward procedure of Treatment of Sludge.Drying can be transformed into fresh sewage sludge can
Storage and the product spread.Microwave drying is to form negative pressure convection current using heating feature inside microwave and air exhauster, is made in filter cake
Outer generation barometric gradient discharge moisture reaches acceleration drying purpose, on the one hand the exhausting system of drying equipment can be leaked water with convective zone
Point, on the other hand make to be formed negative pressure in drier and prevent the dissipation of foul gas, dry products are loose easily broken to be made
Granulated fertilizer material, the effect of energy-saving sterilizing is reached using the characteristics of microwave low-temperature heat and uniform heating, realizes clean manufacturing.
In order that filter cake is typically now had two kinds of ways by enough microwave radiations：The first is to lengthen drier
Length, although both approaches can extend time of the filter cake in drier, take up an area face by the drier lengthened
Product is big, cost of manufacture is high, reduces transporting velocity and is equal to reduce microwave drying efficiency, thus both ways all there is
Drawback.

It is further that microwave caused by the microwave launcher makes the filter cake microwave in the drying box be heated to certainly
Row burning.The organic matter oneself in filter cake is promoted to burn to reach the purpose of decrement loss of weight and deodorization using microwave.
It is further that the quantity of the conveyer belt is greater than the odd number equal to three, the discharging opening and the charging aperture
Not in the same side of the drying box.
It is further that the quantity of the conveyer belt is greater than the even number equal to two, the discharging opening and the charging aperture
Positioned at the same side of the drying box.
It is further that one is provided with outside the drying box positioned at the guide plate described in orlop below conveyer belt, institute
Guide plate is stated to tilt down.
Sludge filter cake is fed into drying box by conveying worm, and is fallen on the superiors' conveyer belt, and filter cake is come therewith
End is conveyed, then turns over and drops down onto on next layer of conveyer belt, filter cake successively transmits repeatedly in several layers of transmission belt, until coming most lower
Layer conveyer belt, the filter cake after dehydration are transferred to discharge outlet by conveying belt of lower floor.Compared with prior art, it is of the present utility model to have
Beneficial effect is：1. successively transmission extends walking path of the filter cake in drying box to filter cake repeatedly in several layers of transmission belt, increase
Filter cake receives the time of microwave irradiation, more effectively reduces the moisture content of sludge；2. filter cake drops down onto by upper strata conveyer belt
During conveying belt of lower floor, it can further rupture and increase its surface so that dewatering efficiency is more；3. the conveyer belt of stacking need to only account for
With longitudinal space, without taking horizontal space, therefore it need to only increase the height of drying box, floor space is small；4. microwave
The purpose for being combined and can realizing fast dewatering decrement is dried and burns, energy consumption is low, more energy saving.
