Abstract
The utility model relates to a material drying device, and the purpose is that aiming at urban dewatered sludge, the utility model is a special device has the function that the ideal drying effect is realized on the basis of a roller drier, and the caking of the sludge can not occur. The utility model is characterized in that the wall of the horizontal roller is provided with a heat-insulating layer, the inside of the roller is provided with a stirring shaft, and a shovelling plate on the inner wall of the roller is provided with a break angle. With the adoption of the utility model, the treatment cost of the 'drying' of sludge is greatly decreased, and qualified intermediate products of organic composite fertilizer are reliable.
Description
The utility model relates to the drying equipment of material.
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.
The purpose of this utility model is: 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 utility model is by combustion furnace, support roller, chain type transmission mechanism, horizontal drum, before, after-poppet, feed hopper and feeding mechanism, discharging mechanism, formations such as flight on the horizontal drum inwall, 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 flight that knuckle is arranged described in the utility model, 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.
The utility model is at the characteristic by municipal sewage gained mud, cylindrical drier has been done following improvement: the one, in horizontal drum, increase the relative horizontal drum in axle center and fixed, have some normal direction to stir the shaft of fork, in the sludge drying processing procedure, allow the relative horizontal drum reverse rotation of shaft, on it stir fork can constantly impact mud in the horizontal drum (for strengthen impact effect stir to stick also can increase horizontal bar), mud can not be lumpd and broken gradually in drying process; Stir fork and can also constantly stir, allow they and mud fully contact to improve the thermal efficiency of hot-air in the tube by the hot-air in the combustion furnace supply horizontal drum; The 2nd, on the horizontal drum wall, increased heat-insulation layer, allow the hot-air of supplying with in the horizontal drum can not pass through the invalid dissipation of barrel, reduced heat loss; The 3rd, change the form that the horizontal drum upper inside wall is divided flight, change this part flight into fold angle type, make these flights that knuckle is arranged or obstruction, delay mud by the horizontal drum front port process of port thereafter of " advancing ", allow mud holdup time long enough in horizontal drum, or all drop on the shaft when mud is fallen in horizontal drum, guarantee that mud is stirred fork (and horizontal bar) and fully impacts, the change of part flight form allows mud just arrive the horizontal drum rear port after sufficiently dry and fragmentation.Above-mentioned key improvement because of wherein containing the problem that organic flocculant lumps, is making full use of " mummification " processing that can only just finish mud under the prerequisite of heat energy through once feeding intake when making the utility model solve the sludge drying processing effectively.The utility model has 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 ".
Below in conjunction with accompanying drawing the utility model is described further.
Figure one is the overall structure schematic diagram of municipal sludge drying equipment.
Figure two is the A-A view of figure one.
Figure three is the B-B view of figure one.
Wherein: 1-combustion furnace, 2-front port, 3-support roller, 4-horizontal bar, 5-stir fork, 6-rear port, 7-discharging machine, 8-rear bearing block, 9-insulation material, 10-flight (its interior angle is towards the front port of horizontal drum) of knuckle arranged, 10-1-the have flight (direction of rotation when its interior angle rotates with cylinder is relative) of knuckle, 11-horizontal drum, 12-shaft, 13-front-end bearing pedestal, 14-feed hopper, 15-scraper plate, 16-discharging machine shell, 17-spiral handspike, 18-material receiving port, 19-flight, 20-discharging opening.
