Description
Technical field
This utility model belongs to the flyash curing process field of waste incineration industry, specifically a kind of based on the flying dust weighed
Automatization's cured system.
Background technology
Centralized burning method is increasingly becoming the major way of China's urban garbage disposal, at the flue gas of garbage burning factory
A number of flying dust can be produced, domestic garbage incineration flyash is at 2016 editions in reason system《National Hazard waste register》Middle quilt
It is listed in " HW18 incineration disposal residue " apoplexy due to endogenous wind, the therefore safe disposal to flying dust proposes technical requirements.
The flyash curing treatment technology commonly used now is cement solidification technology：Flying dust, cement are mixed by a certain percentage and adds
Enter appropriate water（Chelating agen）It is allowed to a kind of method solidifying.Although flying dust have developed into through cement solidification treatment technology ripe,
But need to solve in the automatic accurate measurement conveying of flying dust and cement both powders, certainty ratio mixing always system
Difficult point.
Existing two ways, 1, visually proportioning+disk blender is mixing cured manually：Manually unloading valve will be a certain amount of
Flying dust put in disk blender, add cement and water while stirring, after visual mix homogeneously, be transported to by belt feeder
Thorough piece of brickmaking machine；2nd, metering screw automatic gauge conveying+double-shaft spiral is mixing cured：Flying dust in ash silo passes through electric cinder valve
Entrance is weighed spiral, is transported to double-shaft spiral by spiral quantitative of weighing, and cement is transported to double again by spiral quantitative of weighing
Axle spiral, flying dust and cement add water mixing in double-shaft spiral conveyer, are then transported to thorough piece of brickmaking machine.
But in actual use, existing proportioning and hybrid mode are primarily present and weigh helical feed measuring accuracy not
Height, meter weight is inaccurate, and double-shaft spiral mixing easily blocks difficult cleaning, and manual proportioning haves such problems as flying dust leakage pollution.
Utility model content
In order to solve above-mentioned technical problem present in prior art, this utility model provides a kind of winged based on weigh
Grey automatization cured system, including flying dust storehouse, cement bin, flying dust storehouse is connected to and flying dust storehouse by the first rotation unloading valve
The ash inlet of vertically arranged biaxial rneader, cement bin is connected to twin shaft and is stirred by the second rotation unloading valve and conveying worm
Mix the cement port of entering of machine, water storage tank is connected to the water inlet of biaxial rneader by make-up water pump, arrange outstanding below biaxial rneader
Arm beam type LOAD CELLS, this cantilever type weighing sensor passes through rosette and PLC connects.
Further, the first rotation unloading valve, the second rotation unloading valve and make-up water pump connect with PLC respectively.
Of the present utility model flying dust, cement, water are accurately reflected based on the flying dust automatization cured system weighed
Quality, weighing precision is high, and the mixed proportion control and regulation to flying dust, cement, water are convenient.Biaxial rneader structure is simple, mixing
Uniformly, easy to clean.Defeated ash and cement assembly adopt totally-enclosed, it is to avoid the leakage pollution of flying dust.
Brief description
Fig. 1 is of the present utility model based on the flying dust automatization cured system schematic weighed.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
The cured system process description of flying dust automatization：From incineration plant smoke processing system（Neutralizing tower, cleaner unit）
Flying dust by buried scraper conveyor, bucket elevator be conveyed into flying dust storehouse keep in, cement pre-deposits cement bin.Flying dust passes through
Quantitatively in the ash inlet of injection and the vertically arranged biaxial rneader in flying dust storehouse, it is fixed that cement passes through conveying worm to rotation unloading valve
What amount was transported to biaxial rneader enters cement port, by intake pump and inlet valve quantitative water supply.By design proportioning flying dust with
Cement, water mix in biaxial rneader, and the heavy metal classes in flying dust and chelating agen react, and generate chelate thus being stablized
Change.Flying dust after stabilized and cement slurry, by conveying building block device, are transported to appointed place after making cement brick and fill out
Bury.
As shown in figure 1, of the present utility model based on the flying dust automatization cured system weighed, including flying dust storehouse 1, water
Hopper dredger 2, flying dust storehouse 1 is connected to the ash inlet of the vertically arranged biaxial rneader 4 with flying dust storehouse by the first rotation unloading valve 3,
Cement bin 2 is connected to the cement port of entering of biaxial rneader 4 by the second rotation unloading valve 5 and conveying worm 6, and water storage tank 7 leads to
Cross the water inlet that make-up water pump 8 is connected to biaxial rneader 4, biaxial rneader 4 lower section setting cantilever type weighing sensor 9, be somebody's turn to do
Cantilever type weighing sensor 9 passes through rosette 10 and PLC 11 connects.First rotation unloading valve 3, the second rotary unloading ash
Valve 5 and make-up water pump 8 connect with PLC 11 respectively.
Of the present utility model based on the flying dust automatization cured system weighed by cantilever type weighing sensor 9 with double
Axle blender 4 is combined together, and LOAD CELLS is arranged in the base of biaxial rneader 4, and LOAD CELLS passes through wiring
Box 10 is connected on weighting display instrument, and weighting display instrument passes through PORT COM and PLC 11 real-time communication.Run
When, it is first turned on being arranged under flying dust storehouse 1 the first rotation unloading valve 3, the first rotation unloading valve motor is led to by PLC 11
Cross Frequency Converter Control rotating speed, by adjusting the rotational speed regulation dreg discharge amount of the first rotation unloading valve 3, system is when blender enters flying dust
Metering 1 time, obtains the amount of flying dust；Then the second rotation unloading valve 5 and conveying worm 6 under cement bin are opened, cement amount is same
By the rotational speed regulation of the second rotation unloading valve, system is measured when blender enters cement 1 time, obtains the amount of cement；Open water again
Pump water inlet, system is measured 1 time in water inlet again, obtains the amount adding water, and according to the value of 3 meterings, it is right to realize during proportioning
Flying dust, cement, the automatically controlling of the mass ratio of water.By being arranged on the cantilever type weighing sensor of Double shaft stirring machine base
The weight of 9 real-time biaxial rneaders 4, can rotate the ash load of unloading valve 3, the mud that adds water of conveying worm with precise control first
Amount, the water injection rate of make-up water pump 8 are it is also possible to accumulate flying dust treating capacity by the statistical function of system.
