Abstract
The utility model discloses a double-helical sludge drier for drying sludge in an urban sewage treatment plant, which is suitable for occasions of utilizing and disposing sludge for urban sludge drying with saturated steam heating. The double-helical sludge drier comprises an upper barrel and a lower barrel installed and fixed through a bracket, wherein the two barrels are connected through a hose, the barrels are parallely provided with left and right hollow screws with reverse directions of turning, respectively, and the four screws are provided with hollow blades in a welding manner and rotate synchronously by four chain wheels. While the double-helical sludge drier disclosed by the utility model is used for drying the sludge, the water content of the dried sludge can be conveniently adjusted by adjusting the feed rate, so that the drier is high in heat efficiency, low in manufacturing difficulty and convenient to maintain and repair, and the dried sludge can be used for subsequent comprehensive utilization, safe disposal and the like.
Description
Technical field
The utility model relates to the dry device of a kind of sludge from wastewater treatment plant, is applicable to the mud utilization of municipal sludge mummification of saturation steam heating and the occasion of disposal.
Background technology
Known sludge drier is mainly the high temperature tail vapour producing by fire coal or the thermal source conducting with saturation steam and thermal oil, with the heating of High Temperature Furnaces Heating Apparatus vapour, easily cause dust explosion, and use the steam-heated advantage of supersaturation water clearly: Heating temperature is relatively low, can not cause dust explosion, tail vapour treatment capacity is few, and heat enthalpy value is high.
At present, structurally there are a lot of deficiencies in existing heart paddle type sludge dryer, the hollow shell that it is welded by stainless steel, by cored screw, realize conveying and the stirring of mud, hollow shell and cored screw inside are all full of supersaturated vapor as heat source, and mud is carried out to thermal dehydration.This drier single hop dry trip is long, and the technology difficulty that makes screw rod make and install is high, and cost is high; Screw rod helical pitch is constant, shears transfer rate unchanged; Heating supersaturated vapor can only enter one end, and another brings out, and heating stroke is long, and thermograde is excessive, and heat-transfer effect is undesirable.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, and a kind of duplex sludge drier of efficient energy-saving is provided.
The purpose of this utility model is achieved through the following channels: a kind of duplex sludge drier, it comprises by support installs fixing upper shell and lower shell, two cylindrical shells are connected by upper lower shell connecting hose, parallel respectively in cylindrical shell left cored screw and the right cored screw that rotation direction is contrary be installed, on four screw rods, be welded with hollow blade, all by four sprocket wheels, realize synchronous rotation, the screw rod in upper shell is contrary with the rotation direction of the screw rod in lower shell; Top, upper shell one end is provided with sewage sludge feed bucket, and bottom, lower shell one end is provided with mud product outlet; Upper shell and lower shell are sandwich structure, are respectively equipped with supersaturation heating steam housing steam inlet, housing steam outlet on the two ends barrel of cylindrical shell, and interlayer condensation-water drain is communicated with interlayer; The cylindrical shell two ends of upper shell and lower shell are respectively equipped with axle head steam inlet, axle head steam outlet and cylindrical shell waste gas outlet.Left cored screw and left cored screw support by rolling bearing and copper sheathing bearing respectively.
The utility model duplex sludge drier can be when realizing drying sludge, the water ratio of sludge-drying can by regulating, input speed is convenient to be regulated, and thermo-efficiency is high, and manufacture difficulty is low, maintenance maintenance is convenient, can be used for follow-up comprehensive utilization and safe disposal etc. after drying sludge.

Fig. 1 is the side-looking structural representation of the utility model embodiment.
Fig. 2 is the structural representation of facing of the utility model embodiment.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As Fig. 1, shown in Fig. 2, the utility model duplex sludge drier, it comprises by support 4 installs fixing upper shell 2 and lower shell 5, the effect of upper shell 2 and lower shell 5 is to shorten cylindrical shell length, reduce making and the installation difficulty of cylindrical shell and cored screw, also can be according to the difference of water ratio and temperature in drying sludge process, at upper lower shell, pass to different saturation steam amounts, meet the demand of different water smoking saturation steams, improve dewatering efficiency, two cylindrical shells are connected by upper lower shell connecting hose 10, parallel respectively in cylindrical shell left cored screw 3 and the right cored screw 6 that rotation direction is contrary be installed, left cored screw 3 and right cored screw 6 are respectively by rolling bearing 15 and 9 supportings of copper sheathing bearing, the elongation that effective coordination tubular shaft is heated, left cored screw 3 and right cored screw 6 are made even change helical pitch by the spiral of blade, effect is the section at mud high humidity, helical pitch is little, and hollow blade number is corresponding many, increases the speed that stirs and shear, lower the granularity that mud drying process forms, avoid occurring " sugared cored " phenomenon, along with continuing to increase of helical pitch, stir and shearing rate reduction, reduce the transporting resistance of screw rod to mud, reduce the generation of dust, on four screw rods, be welded with hollow blade 7, all by four sprocket wheels 17, realize synchronous rotation, the rotation direction of the screw rod in the screw rod in upper shell 2 and lower shell 5 is contrary, upper shell 2 tops, one end are provided with sewage sludge feed bucket 14, and lower shell 5 bottoms, one end are provided with mud product outlet 18, upper shell 2 and lower shell 5 are sandwich structure, are respectively equipped with supersaturation heating steam housing steam inlet 8, housing steam outlet 12 on the two ends barrel of cylindrical shell, and interlayer condensation-water drain 11 is communicated with interlayer, the cylindrical shell two ends of upper shell 2 and lower shell 5 are respectively equipped with axle head steam inlet 16, axle head steam outlet 13 and cylindrical shell waste gas outlet 1.
The working process of the utility model duplex sludge drier is as follows: water-containing sludge enters upper shell 2 by sewage sludge feed bucket 14, hollow blade 7 shear agitation through the contrary left cored screw 3 of two rotation directions and right cored screw 6, be sent to upper shell 2 left ends left, through upper lower shell connecting hose 10, fall into lower shell 5, lower shell 5 is identical with upper shell 2 structures, but two cored screws are contrary with the rotation direction in upper shell 2, and mud is transmitted to the right, sludge-drying is finally by 18 outputs of mud product outlet; Meanwhile, upper shell 2 supersaturation heating steam one tunnels enter upper shell 2 mezzanine spaces through housing steam inlet 8, through cylinder inboard wall heat exchange, to mud heating, then flow out through the housing steam outlet 12 of upper shell 2, and jacket steam water of condensation is discharged from interlayer condensation-water drain 11; Another road heating steam enters through axle head steam inlet 16, heat, then warp beam brings out steam ports 13 outflows by left cored screw 3, right cored screw 6 and 7 pairs of mud of hollow blade; The evaporation waste gas that drying sludge produces is discharged by cylindrical shell waste gas outlet 1, concentrates and processes; The flow process of lower shell heating steam is identical with upper shell.
