Abstract
The invention relates to a method and apparatus for drying sludge, which realizes a dedicated plant for ideally drying on the basis rotary-drum drier without agglomerating the sludge, characterized by that, a heat-insulating layer is arranged on the wall of the horizontal drum, an agitating shaft is arranged in the drum, folded plates and folded angles are arranged on the inner walls of the drum. The advantages of the invention are high performance, low cost, and the guarantee for the production of organic composite fertilizer intermediate product.
Description
Technical field
The present invention relates to a kind of method and device thereof of sludge-drying.
Background technology
Containing abundant organic matter and the various trace elements that is beneficial to crop growth in the city dehydrated sludge, is the desirable feedstock of producing compoiste fertilizer.But by municipal sewage through the conventional method processed and this class " mud ", moisture is up to 80%, and it is directly possible hardly as raw materials for production of compoiste fertilizer; If the cylindrical drier of using with existing Chemical Manufacture carries out " mummification " processing to the city dehydrated sludge, generally need just can obtain dewatered sludge 4-5 time repeatedly, and in the processing procedure because of " colloid " effect of organic flocculant wherein, mud also can be formed the moisture and colloid block of the hard and kernel of shell, and they are difficult to be broken and reprocess.With existing cylindrical drier " dewatered sludge " carried out " mummification " processing cost height and do not say, the bulk of gained " dewatered sludge " also makes very difficulty of follow-up compound, granulation.So we can say still do not have the drying equipment that adapts to the city dehydrated sludge characteristic at present.
Summary of the invention
The objective of the invention is to: on the basis of cylindrical drier, at the characteristic realization drying effect ideal of city dehydrated sludge and the special equipment that mud is lumpd.
The present invention is by combustion furnace, support roller, chain type transmission mechanism, horizontal drum, before, after-poppet, feed hopper and feeding mechanism, discharging mechanism, flight on the horizontal drum inwall constitutes, feed hopper and feeding mechanism are positioned at the front port of horizontal drum, discharging mechanism is positioned at the rear port of horizontal drum, and the front port of horizontal drum is higher than rear port, and flight is perpendicular to the inwall of horizontal drum, its that have and preceding (back) horizontal drum port arranged vertical, preceding (back) port towards horizontal drum that has is arranged in parallel, and said horizontal drum wall has heat-insulation layer, and shaft is arranged in the horizontal drum, there are some normal direction to stir fork on the shaft, shaft axially and horizontal drum axial consistent, the two ends of shaft are respectively before bearing block is fixed on, on the after-poppet, the flight on the horizontal drum inwall has knuckle.The described flight that knuckle is arranged, have plenty of with horizontal drum before the part of (back) port arranged vertical flight, the direction of rotation the when interior angle of its knuckle rotates with cylinder is relative; Have plenty of towards the be arranged in parallel part of flight of preceding (back) port of horizontal drum, the interior angle of its knuckle is towards the front port of horizontal drum.
When the present invention has solved sludge drying effectively and has handled because of wherein containing the problem that organic flocculant lumps, making full use of " mummification " processing that only just to finish mud under the prerequisite of heat energy through once feeding intake, not only reduced mud " mummification " processing cost significantly, make that also producing compoiste fertilizer intermediate products qualified, suitable following process has had reliable assurance, has realized at the withering special equipment in city " dewatered sludge ".

The specific embodiment
Embodiment:
As shown in Figure 1, city dehydrated sludge drying equipment thematic structure is roughly the same with general cylindrical drier, but the barrel of its horizontal drum 11 is a double-decker, and described heat-insulation layer is formed by double-deck barrel and insulation material therebetween 9; Horizontal drum has shaft 12 in 11 chambeies, the side (shown in figure two) that cylinder wall rotated from low to high when the axle center of shaft 12 was positioned at horizontal drum 11 rotations, stirring on 12 normal direction of shaft pitches 5 along shaft 12 axially-aligned, stirs on the fork 5 and is arranged with horizontal bar 4; In forward and backward bearing block, front-end bearing pedestal 13 and rear bearing block 8 are separately fixed on the forward and backward support respectively at the two ends of shaft 12; Its interior angle that has the flight of knuckle to have on horizontal drum 9 inwalls is towards horizontal drum 11 front ports 2 directions, shown in 10 among Fig. 1, and its interior angle that has during with horizontal drum 11 rotations direction of rotation relative (to), shown in the 10-1 among Fig. 2.The feeding mechanism of city dehydrated sludge drying equipment is the belt conveyer of belt scraping plate, promptly on the charge face of belt conveyer scraper plate 15 is housed; The discharging mechanism of city dehydrated sludge drying equipment is " spiral handspike formula " discharging machine 7, it is horizontally placed on shown in the rear port 6 times (as Fig. 3), mainly form by discharging shell 16 and spiral handspike 17, flight 19 is arranged on the spiral handspike 17, material receiving port 18 on the discharging machine shell 16 is positioned at horizontal drum 11 rear ports 6 times, and the discharging opening 20 of discharging machine 7 is positioned at the front portion of spiral handspike 17.
