A kind of oven dry for solid waste process, screening feedway
Technical field
The present invention relates to solid waste treatment technology, particularly relate to a kind of oven dry for solid waste process, screening feedway.
Background technology
As everyone knows, feedway is the important component part of solid waste processing equipment, and it processes for being sent in process stove by solid waste, and general solid waste processing equipment enters process stokehold at solid waste will carry out drying and sieving operation.At present, the matching used feedway of existing solid waste processing equipment only just has conveying function, and oven dry before transporting and screening operation also need special equipment to carry out substep to carry out.There is the shortcoming that floor area is large, equipment investment cost is high and treatment effeciency is low.
Summary of the invention
The object of the present invention is to provide a kind of oven dry for solid waste process, screening feedway, it has compact conformation, cost is low and treatment effeciency is high feature, to solve the problems referred to above that in prior art, solid waste processing equipment exists.
For reaching this object, the present invention by the following technical solutions:
A kind of oven dry for solid waste process, screening feedway, it comprises outer case, rotating shaft, actuating device, inside spin conveying blade, external spiral conveying blade and segmentation screening drum, the two ends of described outer case are respectively arranged with inlet point and discharging opening, wherein, described rotating shaft is arranged in described outer case and is driven by actuating device, described inside spin conveying blade is arranged in the rotating shaft at inlet point place, the middle part of described rotating shaft is provided with heater block, the two ends of described segmentation screening drum to be fixed in described rotating shaft and to be provided with external spiral conveying blade in it, and described segmentation screening drum offers sieve aperture, in described outer case, the below of described segmentation screening drum is provided with conveyer, and the top of described outer case is provided with several bleeder lines.
Especially, in described outer case, the described segmentation screening drum of cooperation is provided with the sieve aperture washing and brushing device for preventing sieve pore blockade.
Especially, described heater block is the some fin heats pipes be horizontally installed in described rotating shaft, and described fin heats pipe is by heating source heat supply.
Especially, on described segmentation screening drum, the aperture of described sieve aperture progressively becomes large from feed end to discharge end.
Especially, described conveyer adopts screw conveyer.
Especially, described heating source adopts the high-temperature gas in the process stove of solid waste processing equipment.
Especially, described actuating device comprises reductor, and described reductor drives axis of rotation by driving chain wheel and driving chain.
Beneficial effect of the present invention is, the compared with prior art described oven dry for solid waste process, screening feedway drive inside and outside spiral conveying blade to carry solid waste by rotating shaft, dried by the solid waste of heater block to conveying be arranged in rotating shaft, in course of conveying, by segmentation screening drum, sectional type screening is step by step carried out to the silt that may exist in solid waste, stone simultaneously.Achieve operation, not only compact conformation while carrying out carrying, dry and sieving on a set of load transfer device; Reduce the input cost of equipment; And substantially increase the treatment effeciency of solid waste.

Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
Refer to shown in Fig. 1, Fig. 1 is the oven dry for solid waste process that the specific embodiment of the invention 1 provides, the structural representation sieving feedway.
In the present embodiment, a kind of oven dry for solid waste process, screening feedway comprises outer case 1, rotating shaft 2, actuating device, inside spin conveying blade 3, external spiral conveying blade 4 and segmentation screening drum 8, the two ends of described outer case 1 are respectively arranged with inlet point 5 and discharging opening, described actuating device comprises cycloidal planetary gear speed reducer 6, described cycloidal planetary gear speed reducer 6 is rotated by driving chain wheel and driving chain drive shaft 2, described rotating shaft 2 is arranged in described outer case 1, and the middle part of described rotating shaft 2 is horizontally installed with some fin heats pipes 7, described fin heats pipe 7 is by heating source heat supply, described heating source adopts the high-temperature gas in the process stove of solid waste processing equipment.
Described inside spin conveying blade 3 be fixedly welded on be positioned at described inlet point 5 place rotating shaft 2 on, the two ends of described segmentation screening drum 8 to be fixed in described rotating shaft 2 and its inwall are welded and fixed external spiral conveying blade 4,
Described segmentation screening drum 8 offers the sieve aperture 9 for screening out the foreign material such as silt, stone in solid waste, the aperture of described sieve aperture 9 progressively becomes large from feed end to discharge end, to realize carrying out sectional type screening step by step to solid waste, in described outer case 1, the below of described segmentation screening drum 8 is provided with screw conveyer 10, by screw conveyer 10, the foreign material such as silt, stone fallen bottom outer case 1 is discharged.In described outer case 1, the top of described segmentation screening drum 8 is provided with rotary broom 11, segmentation screening drum 8, while rotation, is cleaned with water sieve aperture it on 9 by rotary broom 11, avoids the silt that sieves out or stone to block sieve aperture 9.
The top of described outer case 1 is provided with several bleeder lines 12, is drawn out in the process stove of solid waste processing equipment by the high-temperature gas produced by bleeder line 12 in drying course.
During work, solid waste first sends into inlet point 5 place, cycloidal planetary gear speed reducer 6 drives rotating shaft 2 to rotate, rotating shaft 2 drives inside spin conveying blade 3 and segmentation screening drum 8 to rotate while rotating, by inside spin conveying blade 3, solid waste is sent in segmentation screening drum 8, by the external spiral conveying blade 4 in segmentation screening drum 8, solid waste is carried to discharging opening direction again, several fin heats pipes 7 in rotating shaft 2 are dried the solid waste being positioned at screening drum 8, silt simultaneously by existing in the 9 pairs of solid waste of the sieve aperture on segmentation screening drum 8 in course of conveying, stone sieves, achieve and carry on a set of equipment, dry and operation while screening.
Above embodiment has just set forth groundwork of the present invention and characteristic; the present invention does not limit by above-mentioned example; without departing from the spirit and scope of the present invention, the present invention also has various change and change, and these changes and change all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
