The specific embodiment
Shown in Fig. 1,2,3,4: rotating filter cartridge type air dust remover, casing 1 are steel construction rectangle tank bracket, the totally-enclosed casing that the tank bracket outside is surrounded as by backplate; The bottom of casing 1 one sides makes rectangle air intlet 3 to be clean, and the top of opposite side makes rectangle and purifies back air outlet slit 14; The top of casing 1 inner chamber is upper junction plate 1-2, the fixing dividing plate 1-1 that connects down in bottom fixedly; The lower horizontal of upper junction plate 1-2 is upper spacer 7-1 and lower clapboard 7-2 fixedly; Slotted section between upper and lower dividing plate 7-1, the 7-2 with the side plate cut-out of casing 1 both sides, forms and the outside atmospheric air import 7 that connects of casing; Lower clapboard 7-2, connect dividing plate 1-1 down the inner chamber of casing 1 be divided into three storehouses: top for purify gas storehouse, back 12, the middle part is that dedusting storehouse 5 and bottom are dust compartment 2.
Described many filter cylinders 6 are installed in parallel in the inner chamber of casing 1, and wherein, left and right two are faced mutually, two the big apart distances in front and back; Described tubular filter cylinder 6 lower ends are sealed with bottom end cover 6-4, and disc bottom end cover 6-4 is connected with cartridge axis 6-1; Filter cylinder 6 upper ends are connected with upper end cover 6-2, and tubular upper end cover 6-2 is connected with cartridge axis 6-1 by many spoke 6-3; Described cartridge axis 6-1 upper end is connected with upper junction plate 1-2 by top chock 11, the lower end pass through step 14 with under be connected dividing plate 1-1 connection.
Shown in Fig. 1,6: upper end cover 6-2 external cylindrical surface is sleeved in the hole of described upper and lower dividing plate 7-1,7-2, and keeps certain clearance with hole wall, and this gap is sealing ring 7-3.The upper end of filter cylinder 6 is an outlet air end, sealing ring 7-3 place is dedusting storehouse 5 and the partition place that purifies gas storehouse, back 12, must solve effective sealing problem, otherwise just forms the air-flow short circuit easily, unclean air in the dedusting storehouse 5 will flow into and purify gas storehouse, back 12, influence outlet index.Utilize the negative pressure characteristics in the dedusting storehouse 5, gap location is communicated with the normal pressure atmosphere, solved this problem.
Described filter cylinder 6, its periphery is made of stainless steel filter cloth, can high-temp resisting high-humidity resisting, acid-alkali-corrosive-resisting, antistatic etc.The density of filter cloth is according to different dust emission Standard Selection.
Filter cylinder 6 is under the driving of main motor 8, according to direction rotation shown in Figure 2, under the driving of blower fan 21, air to be clean enters dedusting storehouse 5 from air intlet 3 to be clean, does under 21 usefulness at blower fan, form spiral air flow from bottom to top along rotating filter cartridge 6, after filter cylinder 6 purifications, enter in the rotating filter cartridge 6, become clean air, air outlet slit 14 is discharged in the atmosphere by blower fan 21 after purifying then, finishes the catharsis of air.
As shown in Figure 7: for effectively lubricating and the cleaning that guarantees step 14, step 14 is a sealed bearing, and it comprises bearing 4-1, bearing block 4-2, is sleeved on the seal box 4-3 of bearing block 4-2 periphery; The lower end of bearing block 4-2 makes lubricant entry 4-4; Seal box 4-3 is connected with compressed air cylinder 15-1 by appendix II16, introduces compressed air, makes seal box 4-3 inside remain malleation, so just guarantees that dust can not fall into raceway, makes effectively cooling and lubricated of bearing.
As Fig. 1,2,3, shown in: described two dust collecting troughs 20 are vertically mounted on the inboard of dedusting storehouse 5 front and back side plates, and its lower end and dust compartment 2 connects; Described chain scraper machine 17 levels are installed in the top of dust compartment 2, and its drive sprocket axle is connected with the motor I 17-1 that casing 1 outside is installed by chain transmission I17-2; Described conveying worm 18 levels are installed in the bottom of casing dust compartment 2, and an end of its screw conveyor shaft passes secondary II18-2 by chain and is connected with the motor II 18-1 that is installed in cabinet 1 outside; The discharging opening of spiral shell Rotatruder 18 is connected with ash-valve 19.
Deduster in the course of the work, rotating filter cartridge 6 passes through action of centrifugal force, the dust that is adsorbed on the filter cylinder surface is thrown to dust collecting trough 20, dust in the dust collecting trough 20 is under the effect of gravity, freely fall into dust compartment 2, by chain scraper machine 17 dust is transported to conveying worm 18, conveying worm 18 focuses on ash-valve 19 and discharges, and finishes ash discharge.
As shown in Figure 1, 2: for guaranteeing the efficiency of dust collection of deduster, adopt the autompulse purging system among the present invention, described pulse purging system 15 comprises: independently be installed in the compressed air cylinder 15-1 of casing 1 one sides, three pulse valve 15-2 and three air-brush 15-4; Described air-brush is the rectangular hollow-core cavity, and the cavity two ends make duckbill nozzle 15-5, and nozzle 15-5 is inserted into the gap location of left and right two filter cylinders 6; Three air-brush 15-4 are upper and lower to face arrangement successively mutually, and the injection direction of nozzle (15-5) and the bus of filter cylinder 6 are tangent; Every air-brush 15-4 is connected with compressed air cylinder 15-1 by appendix I15-3, pulse valve 15-2 respectively.
Shown in Fig. 1,2,5: supply with compressed air by compressed air cylinder 15-1, pulse valve 15-2 intermittently opens successively, and a plurality of filter cylinders 6 are implemented to purge.Nozzle 15-5 with the injection ambient air, forms negative pressure at the high velocity air of filter cylinder 6 surfaces in two filter cylinder slits, filter cloth forms malleation from inside to outside, the dust sucking-off that is embedded in the filter cloth, guarantee the filter cylinder cleaning surfaces, thereby guarantee the efficiency of dust collection substantially constant of filter cylinder.The course of work of pulse valve is as follows: according to dust-laden character, dust content determine between each pulse valve open the time interval and the winding-up duration; As open and be spaced apart 10 seconds, the winding-up duration is 0.2 second; At first open uppermost pulse valve, be its corresponding high speed nozzle air feed, cleaning filter cylinder epimere was closed after 0.2 second; Open the intermediate pulse valve after 10 seconds, cleaning stage casing filter cylinder was closed after 0.2 second; Open nethermost pulse valve more at interval 10 seconds, cleaning hypomere filter cylinder, the 0.2 second afterpulse valve of working cuts out; Open uppermost pulse valve once more 10 seconds at interval, pulse valve periodic duty successively like this makes whole filter cylinder can both obtain cleaning.
Air-brush 15-4 makes independently three sections among the present invention, according to the length of filter cylinder 6, also can make more multistage, and its purpose is:
1, guarantees enough injecting velocities, guarantee the filter cylinder cleaning surfaces;
2, multistage is jetted successively, can reduce moment winding-up air quantity as far as possible, reduces the internal pressure fluctuation of dedusting storehouse, effectively guarantees the atmospheric sealing effect.
Rotating filter cartridge type air dust remover among the present invention is an independently unit unit, and it can independently use, also can multi-machine parallel connection, and promptly air outlet slit 14 combines as a whole by appendix after the purification of each unit, and the air intlet to be clean 3 of each unit combines as a whole.Quantity according to different discharge standard selected cell units.
