Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described:
As Fig. 1, shown in Fig. 2 and Fig. 3, be provided with the metallurgical dust collecting device of fluidized plate, comprise support 1, casing 2, blowing device 3, filter bag 7 and control device, filter bag 7 is located in casing 2, the side of case 2 body is respectively equipped with air inlet 10 and air outlet 9, ash-discharging device 4 is provided with below casing 2, described air inlet 10 is connected with ash bucket 15, ash bucket 15 is connected with ash-discharging device 4, the side of ash bucket 15 is provided with fluidized plate device, fluidized plate device comprises heater 16 and panel, heater 16 is located between the side panel of panel and ash bucket 15, heater 16 is connected with control device.Control device described in the present embodiment comprises PLC and pulse control instrument, and PLC is connected with pulse control instrument and blowing device 3 circuit; Blowing device 3 is arranged on above casing 2, and blowing device 3 is connected with air compression plant by pipeline; Be provided with air intake passage between air inlet 10 and air outlet 9, air intake passage is provided with volume damper 12, and casing 2 is provided with air intake passage switching mechanism 6.
In the present embodiment, described fluidized plate heater 16 comprises steam pipe coil or electric heating, and steam pipe coil is connected with jet chimney by magnetic valve, and magnetic valve is connected with PLC; Electric heating is connected with PLC.Described ash-discharging device 4 is automatic ash-discharging conveying worms.
Described blowing device 3 comprises injection tube, nozzle and magnetic valve, and magnetic valve to be located in injection tube and to be connected with described Pulse Width Control instrument circuit, and pulse control instrument described in the present embodiment comprises Pressure difference feedback formula pulse control instrument.Described filter bag 7 upper end is connected with filter bag installing rack 14, and filter bag 7 lower end is connected with filter bag locating rack 11, is provided with deflector 8 between filter bag 7; Described ash bucket 15 outer wall is provided with hopper wall vibrator, to strengthen the effect of deashing.Described casing 2 is also provided with staircase platform 5 above, and staircase platform 5 is provided with air intake passage switching mechanism 6.
