The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
As Fig. 1, Fig. 2 and shown in Figure 3, low pressure winding-up pulse bag type dust collector, comprise support 1, casing 2, blowing device 3, filter bag 7 and control device, filter bag 7 is located in the casing 2, the lower end of casing 2 and upper end are respectively equipped with air inlet 10 and air outlet 9, be provided with ash-discharging device 4 below the casing 2, described control device comprises pulse control instrument, and pulse control instrument is connected with described blowing device 3 circuit; Described blowing device 3 be arranged on casing 2 above, blowing device 3 is connected with air compression plant by pipeline.
In the present embodiment, described pulse control instrument is a pressure reduction reaction type pulse control instrument; Described blowing device comprises winding-up pipe, nozzle and magnetic valve, and magnetic valve is located at the winding-up pipe and upward and with described pulse control instrument circuit is connected.Described air inlet 10 is connected with ash bucket, and ash bucket is connected with described ash-discharging device 4.According to different dedusting requirements, the outer wall of ash bucket described in the embodiment can also be provided with hopper wall vibrator, to strengthen the effect of deashing.
Ash-discharging device 4 of the present utility model comprises manual dust unloading device and automatic ash-discharging device, and according to different instructions for uses, described manual dust unloading device comprises star-shaped ash unloading valve, and described automatic ash-discharging device comprises conveying worm 13.Described filter bag 7 upper ends are connected with filter bag installing rack 14, and filter bag 7 lower ends are connected with filter bag locating rack 11, are provided with deflector 8 between the filter bag 7.Be provided with air intake passage between described air inlet 10 and the air outlet 9, air intake passage is provided with volume damper 12.Also be provided with staircase platform 5 above the described casing, staircase platform 5 is provided with air intake passage switching mechanism 6.
