Fig. 1 is the schematic diagram above a kind of garbage feeding bucket of waste incinerator of the utility model.
Fig. 2 is the structural representation of pipeline at a kind of waste incinerator primary air nozzle filter screen of the utility model.
Embodiment
Preferably embodiment of the present utility model is described in further detail below.
As depicted in figs. 1 and 2, a kind of self-cleaning device of waste incinerator primary air nozzle filter screen, it includes being located at rubbish
The First air of the top of feed hopper 10 takes air port filter screen 1, and the First air takes the import of air port filter screen 1 to be measured provided with first pressure
Device 2, the First air take the outlet of air port filter screen 1 to be provided with Second device for pressure measurement 3, and the First air takes air port filter screen 1
Entrance is provided with compressed-air atomizer 4, and the compressed-air atomizer 4 takes air port filter screen 1 towards the First air.The First air
The upper, middle and lower of air port filter screen 1 are taken to be respectively equipped with compressed-air atomizer 4.The waste incinerator primary air nozzle filter screen is self-cleaning
Device includes impulse electromagnetic valve 5 and pressure transmitter, and the compressed gas nozzle is connected with impulse electromagnetic valve 5, first pressure
Force measuring device 2, Second device for pressure measurement 3 are connected with pressure transmitter respectively, the pressure transmitter and impulse electromagnetic valve 5
Connection.The model MV-106 of the impulse electromagnetic valve 5.The model PdT-101 of the device for pressure measurement.
As shown in Fig. 2 the self-cleaning device of waste incinerator primary air nozzle filter screen includes the He of the first air compressor 6
Second air compressor 7, the air compressor 7 of the first air compressor 6 and second pass through check (non-return) valve 8 and compressed air respectively
Nozzle 4 connects.The First air takes and gas withdrawal line 9 is additionally provided with air port filter screen 1, the opening of the gas withdrawal line 9
Take air port filter screen 1 relative across First air with compressed-air atomizer 4.It also includes blower fan 10 and filter 11, and the gas returns
Closed tube road 9 is connected by blower fan 10 with filter 11, is reclaimed.
Operation principle is：The air inlet of air port filter screen is taken in original First air and takes air port that device for pressure measurement is set
PdT-101, measurement First air take the import in air port（Outside）And outlet（Inner side）Blast, and draw station-service compressed air line all the way
Air port outlet port is taken to First air, compressed-air atomizer is arranged in filter screen air outlet position.Take air port filter screen clear in First air
When clean, inlet and outlet blast should be basically identical, and after a large amount of dusts or rubbish are adsorbed in filter screen porch, inlet pressure is substantially small
In outlet pressure, if pressure at both sides difference is more than 1500Pa, pressure transmitter output signal, compressed air line is automatically opened up
On impulse electromagnetic valve MV-106, compressed air line nozzle purges by Inside To Outside and cleans filter screen, will adsorb in filter screen
The rubbish and dust in outside are blown back into garbage pool, ensure that First air stability of flow is normal；First air filter screen purging is clean, and both sides are empty
After atmospheric pressure difference is reduced to 300Pa, the magnetic valve in compressed air management is closed automatically, stops filter screen purging work.
