Abstract
The utility model discloses sludge drying processing equipment, comprising a pre-drying tank, a sludge extruding stringing machine, a mixer and a belt-type dryer, wherein the sludge extruding stringing machine is fixedly connected with the top part of the pre-drying tank; the mixer is arranged at the upper part of the sludge extruding stringing machine; and the belt-type dryer is installed at the bottom part of the pre-drying tank. The inner wall of the pre-drying tank is fixedly provided with a plurality of infrared lamps which are arranged in a mode of astral lamps. The sludge drying processing equipment solves the problems that if the interval of sludge strings in the traditional belt-type dryer is too small, the sludge strings are mutually bonded; if the interval is too large, the unit processing capacity is low, the heat of hot air is difficult to effectively use, the drying rate is low, and the like. The sludge drying processing equipment is especially suitable for sludge drying processing aiming at sludge incineration and can improve the industrialization process of sludge drying incineration.
Description
Technical field
The utility model relates to a kind of equipment of sludge treatment, the equipment that particularly a kind of sludge drying is handled.
Background technology
Sewage plant sludge is carried out burning disposal, can make full use of the characteristics that mud contains a large amount of inflammable substances, the mud after handling is acted as a fuel.But the mud that Sewage Plant produces still up to 70%～80%, can't be used for direct burning through its water ratio of mechanical dehydration.Must carry out effective mummification to mud earlier, just can be used for burning.
Belt dryer has advantages such as permeability is good, the residence time can be regulated arbitrarily, material does not have strenuous exercise, dry tenacity is big and enjoys favor, its drying process is at Stainless Steel Wire guipure delivery mud slowly in the transport process, warm air is to transmitting the vertical air-supply of guipure, pass several layers and contain dirt-carrying mud guipure, come in contact heat transfer with mud, thereby water evaporation in the mud is taken out of.In concrete operations, often by mud extrusion machine extruding bunchiness, it is online directly to deliver to Stainless Steel Wire then for mud.Because sewage plant sludge is very sticking, the conventional belt drying machine often can only be spread between one deck and mud string at the mud string on the woven wire must keep big spacing, cause the output of conveyor dryer often lower, the heat of warm air is not fully utilized and just is discharged from simultaneously, has wasted a large amount of thermals source.In addition, one special gluing phase stage (water ratio is about 60%) was arranged in the drying sludge process, in this extremely narrow transition section, mud very easily lumps, the surface is hard, be difficult to pulverize, and the inside is still sposh, make moisture difficulty transfer to the outside, cause drying sludge speed low, the processing cost height.
The utility model content
The utility model provides a kind of sludge drying treatment facility for solving the technical problem that exists in the known technology, and it can improve drying sludge speed, increase drying machine processed in units amount, improve the thermal utilization effect of warm air.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of sludge drying treatment facility, comprise the prebake jar, be fixed in described prebake tank top crowded mud string machine, be arranged on the blender on described crowded mud string machine top and be installed in the belt dryer of described prebake pot bottom, install a plurality of infrared lamps on the inwall of described prebake jar, described a plurality of infrared lamps are arranged to the form of shadowless lamp.
Described a plurality of infrared lamp is arranged in circle in described prebake jar.
The place of being unkitted lamp on the described prebake jar inwall is lined with heat reflection plate.
The number of plies of described infrared lamp setting is 1～4 layer.
Described crowded mud string machine comprises the hopper that is fixed on the mixing tank top and is fixed in discharging housing below the described hopper, described hopper comprises affixed shell and inner casing mutually, the center of described inner casing vertically is connected with motor reducer, the output shaft of described motor reducer connects turning axle, described turning axle is installed between described hopper and the described discharging housing, be connected with at least two uniform circular arc vanes on the described turning axle, the blade tip downside of each circular arc vane and the inner wall shape of described discharging housing are adaptive, described each circular arc vane is provided with stiffening web, a plurality of moulding hole of gathering on the described discharging housing.
Described discharging housing is the inverted cone stage body, and the cone angle of described inverted cone stage body is 60～150 °.
To the attenuation gradually of blade tip thickness, the distance between the inwall of the downside of described blade tip and described discharging housing is 0.5～3mm to described circular arc vane from blade root.
Advantage and the positively effect that the utlity model has are: adopt mud infrared drying pre-treatment and the incorporate method of belt drying, earlier with mud be extruded into the mud string after combustiblematerials mixes, as thermal source mud string outside surface being carried out radiation heating with far-infrared lamp handles, mud string after the prebake is sent into conveyor dryer again and is carried out drying, after mud is extruded into the mud string and forms soft shell, the mud string is layered on the stainless wire mesh of conveyor dryer nearer or stackedly, thereby the raising drying machine is to the processed in units amount and the heat of air is effectively used, and reduces the sludge drying cost; Adopt the far-infrared lamp irradiation technique that the mud outside surface is added heat drying, have that rate of heating is fast, power consumption is few, heating quality is high, the characteristics that heat conversion is high, light from different angles irradiate light, around the mud granule that guarantees to fall enough brightness is arranged all, prevent that mud granule from blocking the generation umbra mutually; Not only can be used as the porosity that raising agent has improved mud with mud blended combustiblematerials powder, portion water in the mud is transferred on the combustiblematerials powder, promote moisture evaporation in the follow-up drying process of mud, thereby improve the drying rate of mud, the combustiblematerials powder can play combustion-supporting effect when the follow-up burning of mud simultaneously; The utility model has solved in the conventional belt drying machine the too small bonding mutually easily of mud string spacing, and spacing is excessive brings again that the processed in units amount is low, the warm air heat is difficult to be used effectively and problem and shortage such as drying rate is low.Being particularly suitable for sludge incineration is the sludge drying processing of purpose; The utility model can promote the industrialization process of sludge anhydration burning.
