Description

A kind of continuous discharge sludge drying device
Technical field
The utility model relates to sludge dryer, is specifically related to a kind of continuous discharge sludge dryer.
Background technology
Containing objectionable impuritiess such as heavy metals in industrial sludge, need through special recycling.Need to dry mud before recycling, to remove moisture contained in mud, reduce the volume and weight of mud, so that transport.Sludge dryer of the prior art mainly contains baking oven type and conveyor belt type.Baking oven type dryer is only suitable for a small amount of sludge treatment, cannot dry through the continuous large batch of mud of row, and uneven to mud heating, and cause localized hyperthermia, mud is easy to harden in baking box; Although conveyor belt type dryer can continuously feeding, but still exist mud heating uneven, thermal cycling is bad, the problem that mud easily lumps, and practical function is undesirable.
Summary of the invention
The purpose of this utility model be to provide a kind of can continuously, effectively mud-water separation, continuous discharge sludge dryer that heats is good.
For reaching above object, the technical scheme that the utility model is taked is:
A kind of continuous discharge sludge drying device, comprise pressure mud machine, screw input feeder, sludge dryer, induced draft fan and water dust scrubber, described screw input feeder is positioned at immediately below the output terminal of pressure mud machine, the output terminal of described screw input feeder connects the opening for feed of sludge dryer, the bottom of described sludge dryer is provided with discharge port, the top of described sludge dryer is provided with offgas outlet, described offgas outlet is through induced draft fan UNICOM water dust scrubber, it is characterized in that, the housing of described sludge dryer is bilayer structure, airtight cavity is formed between described double hull, described housing is provided with the thermal medium entrance of UNICOM's airtight cavity, described housing bottom is provided with thermal medium outlet, the rotating shaft of the hollow of more than one group is provided with in described housing, the two ends of described rotating shaft are through the both ends of the surface of bearing supporting with housing, described rotating shaft is driven by the drive-motor outside housing, circulating thermal medium is connected with in the rotating shaft of described hollow, the outside surface of described rotating shaft is evenly equipped with screw-blade.
Further, what pass in described housing is high-temperature steam.
Further, be connected with high temperature heat conductive oil in the rotating shaft certainly of described hollow, described hollow axle one end is provided with high-temperature heat-conductive oil inlet, and the described hollow axle the other end is provided with high-temperature heat-conductive oil export.
Further, described hull outside is provided with electric heater or Infrared heaters.
Again further, described opening for feed and discharge port lay respectively at the two ends of housing along rotor shaft direction.
After taking above technical scheme, the beneficial effects of the utility model are: mud first sends into sludge dryer through spiral conveyer after pressing mud machine process removal most of moisture wherein, dry the steam passing into high temperature in the crustless sandwich of mud machine, high-temperature steam improves the temperature of mud, promote the evaporation of wherein contained humidity, moisture becomes the offgas outlet of steam from case top through discharging after dedusting in induced draft fan feeding water dust scrubber, preventing pollution.One or more rotating shaft is provided with in housing, the outer wall of rotating shaft is provided with screw-blade, screw-blade both can carry out crushing, stirring to mud, make the abundant exposed evaporation of moisture wherein, rotating shaft is simultaneously hollow setting, be connected with high temperature heat conductive oil in rotating shaft, high temperature has the heat exchange evaporation again of the moisture in mud, reaches and evaporates effect completely.Screw-blade simultaneously can also continuous pusher forward, realizes continuous drying discharging.
