The selection of feelings, landfill are undoubtedly worthless, and this is not only in that land values are expensive, main still from the energy and bio-energy resource
From the aspect of, national requirements is reduced and limits the landfill of sludge.Most of industry sludge dewatering is only with mechanical extruding type sludge
Dehydration, such as belt filter press, plate and frame type filter-press, folded spiral shell machine and centrifugal drier, its dehydrated sludge moisture content exist
70%-90% or so；Select to burn as the means of disposal, the sludge shortage of heat of itself is maintaining its heat demand.So
Such sludge for follow-up storage, transport and burn for it is less economical, this causes current sludge treatment high cost
Major reason, to enterprise's sludge be dried loss of weight, the requirement of volume reduction increasingly increases severely.
At present, domestic sludge drying process, technology are evolving, and the energy mode of employing is mainly direct-heating type and occupies
It is many, i.e., sludge is heated to into more than 100 DEG C using forms such as steam, flue tail gas, electrical heating, makes the moisture content of sludge be changed into water steaming
Gas is discharged；There is problems with the form drying unit：
(1) high energy consumption：Energy requirement is every liter of 620 kilocalorie of evaporation capacity subsistence level, at direct-heating type drying equipment
It is 800-850 kilocalories that reason trade mark claims the thermal demand of its system.
(2) bring secondary pollution：Drying sludge simultaneously brings the tail gas of contaminative, and needing to process device again can be up to standard
Discharge.
(3) drying temperature height brings drying safety problem：The thing that sludge may be evaporated in high temperature drying sludge air-flow
The problems such as matter blast, toxicity, is difficult to avoid that.
In order to solve the above problems, a kind of new belt type sludge drying baker or necessary is designed.

To achieve these goals, this utility model is by the following technical solutions realizing：Belt type sludge drying baker,
Including sludge forming machine, upper strata foraminous conveyer, lower floor's foraminous conveyer, cyclic drying blower fan and thermal-insulating body, thermal-insulating body it is upper
Portion is provided with the pair roller type sludge forming machine that broken molding is carried out to the sludge for luming, and upper strata conveying is provided with inside thermal-insulating body
Guipure, lower floor's foraminous conveyer, cyclic drying blower fan, upper strata foraminous conveyer are arranged on the lower section of sludge forming machine, lower floor's transmission net
Band is arranged on the lower section of upper strata foraminous conveyer, and cyclic drying assembling is protected in the fixed plate bottom of lower floor's foraminous conveyer sidepiece
Warm box house is formed with sealing and circulating drying space.
Preferably, described upper strata foraminous conveyer, lower floor's foraminous conveyer are using outside small opening formula rustless steel foraminous conveyer
Polyester square hole net.
Preferably, described cyclic drying blower fan is using without scroll casing type centrifugal blower.
Preferably, described thermal-insulating body is quick distachable formula PU plate.
The beneficial effects of the utility model：High degree of automation, energy consumption are low, will not bring secondary pollution, energy-conserving and environment-protective, and
Drying temperature is low, effectively prevent the safety problems such as material blast, toxicity, and safety is higher, effectively increases cold drying gas
Stream dehumidification ability, with wide market application foreground.
Description of the drawings
With reference to the accompanying drawings and detailed description describing this utility model in detail；
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the flow chart that this utility model is used for sludge loss of weight dehumidification.
Specific embodiment
Technological means, creation characteristic, reached purpose and effect to realize this utility model is easy to understand, below
With reference to specific embodiment, this utility model is expanded on further.
With reference to Fig. 1-2, this specific embodiment is employed the following technical solutions：Belt type sludge drying baker, including sludge molding
Machine 1, upper strata foraminous conveyer 2, lower floor's foraminous conveyer 3, cyclic drying blower fan 4 and thermal-insulating body 5, the top of thermal-insulating body 5 are installed
There is pair roller type sludge forming machine 1, upper strata foraminous conveyer 2, lower floor's foraminous conveyer 3, cyclic drying wind are installed inside thermal-insulating body 5
Machine 4, upper strata foraminous conveyer 2 are arranged on the lower section of sludge forming machine 1, and lower floor's foraminous conveyer 3 is arranged under upper strata foraminous conveyer 2
Side, cyclic drying blower fan 4 are arranged on the fixed plate bottom of 3 sidepiece of lower floor's foraminous conveyer, and cyclic drying blower fan 4 is using without scroll casing type
Centrifugal blower, has been internally formed sealing and circulating drying space in thermal-insulating body 5.
It should be noted that described upper strata foraminous conveyer 2, lower floor's foraminous conveyer 3 are conveyed using small opening formula rustless steel
The outer polyester square hole net of guipure.
Additionally, described thermal-insulating body 5 is quick distachable formula PU plate.
This specific embodiment provides adiabatic sludge drying environment by thermal-insulating body 5, and cyclic drying blower fan 4 provides drying
Circulation wind-power, carries out forced heat-exchanging to wet mud, and the sludge of caking is carried out broken molding by sludge forming machine 1 first, with
Profit increases heat exchange area, there is provided sludge after molding is delivered to lower floor's foraminous conveyer 3 by heat exchange efficiency, upper strata foraminous conveyer 2, while
With allow sludge and circulated air to exchange heat, lower floor's foraminous conveyer 3 is delivered to dewatered sludge discharge bucket by sludge is dried, at the same with allow sludge with
Circulated air exchanges heat.
This specific embodiment aims at drying sludge and provides sealing and circulating drying space, and the sludge drying baker form can be even
It is continuous, automatically sludge is dried, while for provide sludge at low temperature drying heat pump efficiency provide effectively supply, return air temperature it is poor and
