Abstract
The utility model discloses a high-efficiency pulse cloth drum dust filter, and relates to grain processing machinery, in particular to ventilation and dust removal equipment for purifying gas containing dust and collecting a dust material in treatment of a flour mill. The high-efficiency pulse cloth drum dust filter comprises an upper box, a middle box and a lower box, wherein the upper box is provided with a purified gas outlet; the middle box is provided with a dust-containing gas inlet and is connected below the upper box; the lower box is connected below the middle box; the periphery of the lower box is connected with a supporting rod; the upper box is connected with an electromagnetic pulse straight-through valve; the electromagnetic pulse straight-through valve is connected with an air pocket; the air pocket is connected on the outer side of the upper box and is connected with an air pump through a pipeline; a plurality of vertically arranged spring cages are connected in the middle box; a filter bag is sleeved outside each spring cage respectively; an air closer and a scraping plate speed reducer are connected below the lower box; an output end of the scraping plate speed reducer is connected with a flat dust scraping plate; and the flat dust scraping plate is arranged in the lower box. The high-efficiency pulse cloth drum dust filter has the advantages of high blow-back air pressure, good filter bag cleaning effect, easiness in replacement and convenience in maintenance and repair.
Description
Technical field
The utility model relates to Cereals Processing Machines, relates in particular to flour mill's processing and is used for the gas that contains dust is purified, and collect the dust removal by ventilation equipment of particulate dust.
Background technology
Original action of low-voltage pulse dirt catcher exists counter-blowing wind-pressure power low, and the filter bag cleaning effect is poor, and it is difficult that the high-voltage pulse dirt catcher exists filter bag to change, defectives such as maintenance inconvenience.
Summary of the invention
The purpose of the utility model is in order to overcome the deficiency of prior art, provides that a kind of counter-blowing wind-pressure power is high, the filter bag cleaning effect is good, it is simple to change, maintenance high-efficiency pulse cloth tube dirt catcher easily.
The purpose of the utility model is achieved in that high-efficiency pulse cloth tube dirt catcher, comprises upper box, middle casing and lower box, and the pure qi (oxygen) outlet is set on the upper box; Dirt gas inlet is set on the middle casing, and middle casing is connected the below of upper box, the below of casing during lower box is connected; The periphery of lower box connects support bar, connects the electromagnetic pulse straight-through valve on the said upper box, and the electromagnetic pulse straight-through valve connects gas bag; Gas bag is connected the outside of upper box, and gas bag connects air pump through pipeline; Connect several vertical spring cage bones of arranging in said in the casing, each spring cage bone is nested with filter bag outward respectively; The below of said lower box connects airlock and rubbing board decelerator, and the output of rubbing board decelerator connects the flat hawk of drawing together, and puts down to draw together hawk and be arranged in the lower box.
During work, when dusty gas after therefrom casing air inlet tangential gets into casing, a part because action of centrifugal force falls into ash bucket along the barrel rotation, plays elementary dedusting effect than the coarse granule dust.The dust that another part is thinner is trapped in outside the filter bag; Purified gas passes filter bag entering upper box and is discharged by exhaust outlet; When the dust on filter bag surface, when load increases in the filtration state, the dirt catcher resistance also increases, and maintains in the limited range for making equipment, must carry out deashing and reach the purpose that dust reduces resistance; Adopt the way of the high-voltage pulse jetting deashing of controller control; Make each filter bag in its winding-up and induce under the effect of source of the gas and cause the instantaneous expansion of filter bag, shake off dust, and discharge by ash exhauster.
The upper box of the utility model adopts external circular high pressure gas bag, and six following filter bag blowback cleanings of every solenoid control are adopted from gas bag to end progressively to become big winding-up mouth, guarantee the former pressure of gas, improve the depositing dust cleaning effect.Filter bag in the middle casing supports and adopts spring cartilage frame, and it is convenient that filter bag maintains, keeps in repair, changes.Lower box adopts flat rubbing board control of dust mechanism, and dust catching efficiency is high, and power consumption is low, has reduced device height simultaneously, reduces the equipment usage space.
For the ease of maintenance, on the said middle casing raising middle flask body access door is set.
In like manner, the ash bucket manhole is set on the lower box.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Among the figure, 1 gas bag, 2 electromagnetic pulse straight-through valves, 3 cards, 4 dirt gas inlet, 5 spring cage bones; 6 filter bags, the 7 flat hawks of drawing together, 8 rubbing board decelerators, 9 airlocks, 10 support bars, 11 air pumps; 12 lower boxes, 13 ash bucket manholes, casing in 14,15 raising middle flask body access doors, the outlet of 16 pure qi (oxygen)s, 17 upper boxes.
The specific embodiment
As shown in Figure 1; For high-efficiency pulse cloth tube dirt catcher, comprise upper box 17, middle casing 14 and lower box 12, pure qi (oxygen) outlet 16 is set on the upper box 17; Connect electromagnetic pulse straight-through valve 2 on the upper box 17; Electromagnetic pulse straight-through valve 2 connects gas bag 1, and gas bag 1 is connected the outside of upper box 17, and gas bag 1 connects air pump 11 through pipeline.Middle casing 14 is connected the below of upper box 17; Dirt gas inlet 4 and raising middle flask body access door 15 are set on the middle casing 14; The upper end of middle casing 14 connects card 3; Connect several vertical spring cage bones 5 of arranging in the middle casing 14, be nested with filter bag 6 respectively outside each spring cage bone 5, each upper end that is nested with the spring cage bone 5 of filter bag 6 is connected to respectively on the card 3.The below of casing 14 was provided with ash bucket manhole 13 during lower box 12 was connected on the lower box 12, and the periphery of lower box 12 is fixedly connected support bar 10.The below of lower box 12 connects airlock 9 and rubbing board decelerator 8, and the output of rubbing board decelerator 8 connects the flat hawk 7 of drawing together, and flatly draws together hawk 7 and is arranged in the lower box 12.
