Description

Low temperature belt-type drying system

Technical field

The utility model relates to sludge treatment device fields, in particular to are used for the anhydration system of Treatment of Sludge.

Background technique

Sludge at low temperature dehumidifying desiccation machine is dried to sludge using hot air circulation dehumidification by condensation using dehumidifying heat pump；Including removing Damp and hot pumping system, mesh belt drying system, electric autocontrol system etc.；Can sufficiently 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 warp 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 by the slitting molding machine that desiccation machine carries, fallen by gravity slow by the wet wet pug storehouse of desiccation machine On the mesh belt gone slowly away, hot run test is risen by mesh belt bottom with fast speed, wet by sludge drying during contacting with sludge Air then enters dehumidification system, makes humid air temperature lower than dew point by way of cooling, steam, which is able to condense and be discharged, is System is made the atmosphere temperature rising after " being dehydrated " become hot dry air by heating method, is sent into mesh belt 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, for the available appropriate place of sludge Reason, tradition is general to carry out the method for solid-liquid two-phase laminated flow using plate and frame filter press to carry out sludge dewatering treatment, 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 and flocculant carry out hybrid reaction, then through gravity dehydration, wedge pressure dehydration, low pressure Dehydration, middle press-dehydrating and high press-dehydrating, gradually reduce sludge water content, 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 requires to install matched 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 operator.

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, can remain sludge when conveying sludge, if sludge cleaning is not in time, equipment again Load excessive when secondary starting has deleterious effect to carrying roller, bearing and vibrating motor, or even burns motor.

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 the amount of delivery pump output in use, it is excessive to will cause disposable conveying capacity, makes Delivery pump blocking and can not normal use, so the delivery pump of degree of the needs prior art improves.

In order to improve the efficiency of belt-type sludge drier, people seek the dry-form by changing sludge constantly to reach 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 to be able to achieve, therefore to item The extrusion device of shape sludge has biggish 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 , can be containing sundries such as hair, fibers in sludge when mud is cut, some can be mingled in sludge goes out inside slitting device It goes, some can then be stuck in the sieve pore of slitting device, with increasing for slitting device slitting number, gradually block slitting device Sieve pore will 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 effect is poor, and large labor intensity, 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 processing, wherein because low temperature belt-type drying machine mechanical wear, environmentally friendly foul smell, in terms of all have it is apparent excellent Gesture, therefore low temperature belt-type drying machine is mostly used to carry out the drying and other treatment of sludge, 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 mesh belt conveyor of machine, usually not no side, when using desiccation machine dewatered sludge, sludge is dropped to by self gravity When on conveyer belt, inevitably having some sludge can splash down outside conveyer belt out, if things go on like this, will accumulate 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.
