Description
Technical field
The utility model is related to a kind of filter drum type precipitator, belongs to air purification field.
Background technology
With the sustained and rapid development of China's industrial sector, all kinds of dust and suspended particulate substance produced in production process into
The most important pollution sources polluted for indoor and outdoor air and factory floor.The suspension dust of high concentration is to cause air visibility
Decline main factor, and if some suspension dust be easier to chemically react under optimum conditions, it is inflammable and explosive,
The serious life and production safety for threatening the people, is also to cause the root of the occupational diseases such as pneumoconiosis.Since nearly half a century, by
Increasingly increase in demand of the people in terms of such as traffic, the energy, the air pollution problems inherent sharp deterioration caused.It is especially near
The haze weather using PM2.5 as leading factor in the whole nation is shrouded over year, people is paid attention to environmental protection further, dedusting is recognized
Intellectual is also generally improved, and related functional department has also formulated more strict atmosphere pollutants emission standardses, so that dedusting
Technology has obtained continuing to develop, and possesses vast potential for future development.
Different according to dust catching principle, conventional cleaner mainly has mechanical dust collector, electric cleaner, filtering at present
Deduster and scrubber.Wherein filter collector makes dust-contained airflow by filtrate by grit separation and collection, point self-filtering
With surface filtration two ways, efficiency of dust collection is generally 90%~99%.Filter drum type precipitator is also a kind of filter collector, its
Operation principle is mainly a part of particle particle diameter that dusty gas enters in dust collector box body interior air-flow section sudden enlargement, air-flow
Larger dust is directly dropped in ash bucket in the presence of gravity and inertia force without cartridge filter；Remaining fine size, density are small
Dust go to filter cylinder with air-flow, under the influence of cloth youth diffusion and the combined effect such as sieving, be blocked in by filtrate outside filter cylinder,
Clean gas to discharge pipe from discharging in filter cylinder in the presence of blower fan, and laying dust falls into after ash bucket and shifted, so as to reach the mesh of dedusting
's.
Filter drum type precipitator can be divided into vertical and horizontal two kinds of classifications, Horizontal filtration drum formula deduster according to filter cylinder arrangement mode
Filter cylinder be disposed with horizontally disposed and be in tilted layout two kinds of forms.However, no matter which kind of arrangement, no matter upper air inlet or under
, there is filter cylinder upper face fouling phenomenon in air intake.The dust stratification of filter cylinder upper face is after deashing, due to the effect of gravity, also
Filter cylinder uper side surface can be deposited in, the filtration of such filter cylinder this part of upper face in actual filtration increases with regard to very little
Plus the resistance of filter drum type precipitator, reduce efficiency of dust collection.

Embodiment
Illustrate embodiment of the present utility model below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, filter drum type precipitator includes：Casing 1, filter cylinder 2, worm gearing 3, deashing mechanism and
Ash bucket 5.
Air inlet 6 is opened in the top of casing 1, and air outlet 7 is opened in the bottom of casing 1.
Airflow uniform distribution plate 8, is arranged on the lower section of air inlet 6.
Card 9 is provided with casing 1, filter chamber 10 and air-purifying chamber 11 will be divided into inside casing 1.Air inlet 6 is opened in filtering
On room 10, air outlet 7 is opened on air-purifying chamber 11.
Filter cylinder 2 is arranged in filter chamber 10, and worm gearing 3 and deashing mechanism are arranged in air-purifying chamber 11.Such as Fig. 2 and
Shown in Fig. 3, worm gearing 3 includes worm screw 31, screw thread rack 32, worm-gear toothing 33 and handle 34.
The arrangement of filter cylinder 2 is horizontal arrangement, by top cover 21, metal framework 22, pleat shape filtrate 23 and base 24 4
It is grouped into；One end of metal framework 22 of filter cylinder 2 is connected with card 9 and stretches into air-purifying chamber 11, and the other end is through casing 1 exposed to filter
Outside cylinder type dust catcher.
Excellent sealing and there is relative motion between filter cylinder 2 and card 9, connect between filter cylinder 2 and card 9 for rotatory sealing
Connect.
The number of filter cylinder 2 is three in the present embodiment, and vertical direction is arranged successively.
As shown in Figures 2 and 3, worm gear teeth 33 is carved with or be welded with one end of the stretching of metal framework 22 card 9, is used as snail
The Worm-gear assembly of bar transmission mechanism 3.
Worm gearing 3, including worm screw 31 and worm-gear toothing 33.Moved back and forth by the spiral of worm screw 31, while band
Move multiple filter cylinders 2 to rotate, worm screw 31 is the elongate cylinder bar for being carved with screw thread rack 32, its axis and the metal that worm gear is filter cylinder 2
The axis of framework 22 is vertical, and casing 1 is stretched out in the one end of worm screw 31, welds handle 34.
During deashing, when handle 34 is rotated, worm screw 31 is rotationally advancing or retreated, and screw thread rack 32 is engaged with worm-gear toothing 33
Effect causes the metal framework 22 of filter cylinder 2 to rotate 90 degree, stops handle 34 and rotates.Now the upper surface of filter cylinder 2 turn to side or
Below so that fall the dust stratification in the upper surface of filter cylinder 2 after deashing again and drop to the bottom of filter chamber 10 with rotation, be finally slipped to ash bucket
