Description
Technical field
The present invention relates to sludge treatment device fields, more particularly to are used for the anhydration system of Treatment of Sludge.
Background technology
Sludge at low temperature dehumidifying desiccation machine is dried using hot air circulation dehumidification by condensation to sludge using dehumidifying heat pump；Including removing
Damp and hot pumping system, mesh belt drying system, electric autocontrol system etc.；Can fully realize to sludge carry out " minimizing, stabilisation,
Innoxious and recycling " processing；Final mud granule, which can be done, mixes fuel burning, burning, construction material, bio-fuel etc.；Sludge passes through
It crosses original conventional sewage dewaterer to be dehydrated to 70%-83% or so, be removed by conveyer or gravity from falling mode and enter low temperature
Sludge is cut into " noodles " shape, is fallen by gravity slow by the wet wet pug storehouse of desiccation machine, the slitting molding machine carried by desiccation machine
On the guipure gone slowly away, hot run test is risen by guipure bottom with fast speed, wet by sludge drying during being contacted with sludge
Air then enters dehumidification system, makes humid air temperature be less than dew point by way of cooling, steam, which is able to condense and be discharged, is
System, by mode of heating so that the atmosphere temperature rising after " dehydration " becomes hot dry air, is sent into guipure desiccation to plant area's sewage conduct
System continues dewatered sludge, and air recycles in overall process, therefore emission-free generation.
The belt type sludge deep dehydration machine of the prior art has the following problems：1, in order to which sludge can obtain appropriate place
Reason, tradition generally carry out the method for solid-liquid two-phase laminated flow to carry out sludge dewatering treatment using plate and frame filter press, but such
Processing mode is unable to deep dehydration, and water content is higher in the sludge of output, existing dirty using belt in order to improve this problem
Mud dewaterer, its dewatering type is that sludge carries out hybrid reaction with flocculant, then through gravity dehydration, wedge pressure dehydration, low pressure
Dehydration, middle press-dehydrating and high press-dehydrating, make sludge water content gradually reduce, are finally discharged at solids, although improving in sludge
The higher problem of water content, but dehydration complexity is cumbersome, machinery takes up a large area, wasting manpower and material resources, increase use at
This；2, the mode of drying of existing belt mud dewatering equipment is open architecture mostly using hydrofuge+condensation, in order to avoid
The exhaust gas that organic matter volatilization generates in dehydration is discharged into air, is polluted the environment, existing belt type sludge dehydration
Machine is required for installing mating complicated deodorization device in dehydration device, and deodorization device needs to grasp because of the structural factor of its own
Make personnel periodically it is cleared up and is checked, increases the working strength of operating personnel.
The sludge delivery pump of the prior art has the following problems：1, there are some defects, conveyings for present sludge delivery pump
Pump cleaning is important one of machine maintenance, and sludge can be remained when conveying sludge, if sludge cleaning is not in time, equipment again
Load excessive when secondary startup has deleterious effect to carrying roller, bearing and vibrating motor, or even makes burn-down of electrical machinery.
In existing delivery pump, it is not provided with differential mechanism, in delivery pump so being unable to control transmission axle when in use
Rotation rate, be also just unable to control in use delivery pump output amount, disposable conveying capacity can be caused excessive, made
Delivery pump block and can not normal use, so the delivery pump of degree of the needs prior art is improved.
In order to improve the efficiency of belt-type sludge drier, people constantly seek to reach by changing the dry-form of sludge
This purpose, currently, the extrusion way of sludge mainly has pair roller type, tabletting type, strip extruded type etc., by continuous knowhow
Accumulation, it has been found that the sludge of bar shaped extruded type is fast and efficiently dried because its surface area is larger so as to realize, therefore to item
The extrusion device of shape sludge has larger demand, and bar shaped sludge extrusion device is also constantly being innovated, but existing belt-type drying
Machine sludge slitting device is needed to improve there are still part deficiency.
The desiccation machine sludge slitting device of the prior art has the following problems：1, with the quickening of urban development step, city
More and more sludge are produced in city's sewage discharge pipe network, the dopant species in sludge are also more and more, and slitting device is to dirt
When mud is cut, the sundries such as hair, fiber can be contained in sludge, some can be mingled in sludge to go out inside slitting device
It goes, some can then be stuck in the sieve pore of slitting device, as slitting device cuts increasing for number, gradually block slitting device
Sieve pore can cause the damage of sludge slitting device because carrying out shearing-crushing without relevant equipment when serious；2, big on the market
The slitting function of most belt-type drying machine-cut strip devices gradually tends to be perfect, but the subsequent cleaning work of slitting device is still
It cannot get the great attention of manufacturer, existing sludge slitting device manually cleans mostly or using manually being cleared up
Machine cannot be guaranteed to carry out machine comprehensive cleaning, and cleaning performance is poor, and labor intensity is big, increases staff's
Working strength, it is time-consuming and laborious.
The sludge drying of the prior art has the following problems：The sludge drying processing of the prior art mostly uses at heat drying
Reason, does sludge using paddle formula desiccation machine, vertical polydisc desiccation machine, rotating disc type desiccation machine and low temperature belt-type drying machine etc.
Change is handled, wherein because low temperature belt-type drying machine all have in mechanical wear, environmentally friendly foul smell, operational safety etc. it is apparent excellent
Gesture, therefore the drying and other treatment that low temperature belt-type drying machine carries out sludge is mostly used, low temperature belt-type drying machine is to utilize dehumidifying heat pump pair
Sludge is using the technology that hot air circulation dehumidification by condensation is dried come dewatered sludge, but to lack sludge former for existing low temperature belt-type drying machine
The uniform stirring function of material, at the same it is not dry enough by the hot-air of dehumidifying heat pump, it can all influence the dirty knot for arriving mud drying and other treatment
Fruit.
The low temperature belt-type drying machine sludge net belt conveying apparatus of the prior art has the following problems：Existing low temperature belt-type drying
The guipure conveyor of machine, usually not no side, when using desiccation machine dewatered sludge, sludge is dropped to by its own gravity
When on conveyer belt, inevitably having some sludge can splash down outside conveyer belt, if things go on like this, will be accumulated greatly in the bottom of desiccation machine
The sludge of amount, and can be extremely inconvenient when the sludge of bottom is in cleaning, so needing the net to existing low temperature belt-type drying machine
The improvement in structure is carried out with conveying device.
