The specific embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail.
The feed arrangement of a kind of sludge incinerator as shown in Figure 1-2, comprise double helix charger 15, casing 1 top of described double helix charger 15 is provided with dewatered sludge charging aperture 2, and below is provided with wet sludge inlet 3, casing 1 is built-in with double-screw shaft 4, and double-screw shaft 4 is provided with helical blade 5; The material feeding end of conveying worm is stretched out in one end of double-screw shaft, the reducing motor that the speed changer 9 being connected by motor 8 and with motor forms is connected with the double-screw shaft 4 that stretches out material feeding end by chain sprocket assembly, and (sprocket wheel 6 of chain sprocket assembly is arranged on double-screw shaft, chain 7 is arranged on speed changer), the rotating speed of the adjustment of rotational speed double-screw shaft by regulation and control motor and speed changer, and then transporting velocity and the conveying capacity of change mud; The other end of double-screw shaft 4 is connected to the charging aperture of sludge incinerator 16 by flange, the good seal performance that flange connects is not high to the required precision of shell 1, and installation and removal are convenient, save processing cost.
Because the temperature in incinerator is about 850 ℃～950 ℃, for preventing that shell 1, double-screw shaft 4 and helical blade 5 from high temperature damaging, casing 1 is connected part for high-strength refractory material housing end 10 or water-cooling apparatus with sludge incinerator 16.
While stopping in equipment fault carrying dry wet mud to double helix charger 15; high-temperature flue gas in incinerator or flare very easily enter in conveying worm; cause material tempering spontaneous combustion and damage double helix charger 15; 4～6 ventilating openings are set for this reason on casing 1; in the time that dry wet mud stops charging; ventilation unit is opened; to the interior ventilation of double helix charger 15; make its pressure be greater than the pressure in incinerator; stop high-temperature flue gas or flare to enter in double helix charger 15, thereby double-screw shaft 4, helical blade 5 and casing 1 are played a protective role.
Wherein, the casing 1 of double helix charger 15 is square column type machine, and the port cross section of dewatered sludge charging aperture 2 is square ports wide with casing 1, with casing 1 installation in 90 °; The port cross section of wet sludge inlet 3 is circular, is 45 ° of material feeding ends to conveying worm (near one end of dewatered sludge charging aperture and wet sludge inlet) tilts to install with casing 1; The port center line of dewatered sludge charging aperture 2 and wet sludge inlet 3 overlaps, and guarantees that charging is steady, and the mud that makes to do, wets evenly mixes within the shortest time, enters smoothly in double helix charger 15, and phenomenon can not result in blockage; And the port cross section of dewatered sludge charging aperture 2 is greater than the port cross section of wet sludge inlet 3, this be because: the dewatered sludge of moisture content 30%～40% is solid-state, and poor fluidity is easily built bridge, and therefore selected bore is larger, prevents from stopping up; Moisture content is that 75%～85% wet mud is plastic state, and mobility is relatively better, and general flow velocity slightly very much not can result in blockage.
A kind of sewage sludge feed treatment system as shown in Figure 3, mud handling capacity is 720t/d, comprises wet sludge delivery pump 11, wet mud discharge meter 12, dewatered sludge measuring tank 13, sewage sludge feed spiral 14, double helix charger 15 and incinerator 16.Wet sludge delivery pump 11 is connected to the wet sludge inlet 3 of double helix charger 15 by wet mud discharge meter 12, dewatered sludge measuring tank 13 is connected to the dewatered sludge charging aperture 2 of double helix charger 15 through sewage sludge feed spiral 14, the discharge end of double helix charger 15 is connected to sludge incinerator 16.
The concrete streamline of this sewage sludge feed treatment system is:
1, the dewatered sludge that is first 30%～40% by moisture content is transported in dewatered sludge measuring tank 13, and after Weighing, mud is delivered to the dewatered sludge charging aperture 2 of double helix charger 15 by the supporting sewage sludge feed spiral 14 of bottom land;
2, the wet mud of moisture content 75%～85% is transported in wet sludge delivery pump 11, under the effect of pump, wet mud is delivered to the wet sludge inlet 3 of charger 15 by pipeline;
3, dewatered sludge and wet mud mixed stirring in double helix charger 15 moves forward, and evenly mixed dry wet mud is transported to and in incinerator 16, carries out burning disposal.
Wherein, the dewatered sludge amount that enters double helix charger 15 is mainly controlled by mud measuring tank 13, the conveying capacity of mud measuring tank 13 is 0.2～5t/h, supporting sewage sludge feed spiral 14 adopts VFC, change speed of screw shaft by the frequency of adjusting feed auger, and then adjust dewatered sludge conveying capacity; The wet sludge quantity that enters double helix charger 15 can be controlled by wet sludge delivery pump 11, the same VFC that adopts of double helix charger 15, by regulating the frequency of conveyer to change the conveying capacity of wet mud, wet mud discharge meter 12 is installed simultaneously on the pipeline between wet sludge delivery pump 11 and double helix charger 15, is convenient to the wet mud conveying capacity of on-line monitoring and adjusts in time as required.
The dewatered sludge charging aperture 2 of double helix charger 15 is of a size of 558 × 600mm, is 90 ° of installations with casing 1; Wet sludge inlet 3 is the circle of diameter 250A, is 45 ° of installations with casing 1.
According to the inlet amount of dry wet mud, granularity, the parameters such as viscosity, the helical axis diameter of the double helix charger 15 of selecting is 100A, helical blade diameter is 280mm, pitch is 210mm, the object of considering helical feed mud is to produce axially-movable, the degree increase of tangential motion can make the transfer efficiency of conveying worm reduce, simultaneously in order to reduce the resistance of conveying worm axially-movable, housing madial wall is ensured certain roughness by we, and housing bottom reduces its coefficient of friction as far as possible, guarantee that mixed dry wet mud smooth delivery of power is to burning disposal in incinerator.In addition, select suitable lead angle, not only can obtain larger axial motive force and axial velocity, and be conducive to eliminate the impact of pack completeness variation on helical axis distortion.
As mentioned above; embodiment of the present utility model is explained; obviously, as long as do not depart from fact utility model point of the present utility model and effect, the distortion that will be readily apparent to persons skilled in the art, within being all included in protection domain of the present utility model yet.
