Description
Technical field
The present invention relates to a kind of cellular-type filter element device.
Background technology
Existing filter element device such as Fig. 1, Fig. 2 and shown in Figure 3, comprise support a1, filter core a2, exhausting system (not shown), cylinder a3, lifting disk a4, hollow shaft a5 and several anti-blowpipes a6, filter core a2 is cylindric, filter core a2 has a cavity, the top of filter core a2 is provided with the exhaust outlet a21 that is communicated with cavity, it is upper and can order about lifting disk a4 to move up and down and control the unlatching of exhaust outlet a21 or close that cylinder a3 is installed in support a1, anti-blowpipe a6 is installed in the filter core a2 cavity and with hollow shaft a5 and is communicated with, and hollow shaft a5 can pass into compressed air.This filter element device has an exhausting state and a cleaning state;
As shown in Figure 1, when this filter element device is in the exhausting state, cylinder a3 drives lifting disk a4 rising and makes exhaust outlet a21 be in open mode, exhausting system sucks the gas of the cavity of filter core a2 from exhaust outlet a21, make the cavity of filter core a2 be in negative pressure, the air of filter core a2 outside and the mixture of dust flow to filter core, reach discharge standard through filter core a2 processing filtered air and discharge from exhaust outlet a21;
As shown in Figure 2, when this filter element device is in the cleaning state, clearance time according to default, cylinder a3 drives lifting disk a4 decline shutoff exhaust outlet a21 and makes exhaust ports in closed condition, this moment, the cavity at filter core a2 formed an annular seal space, send into compressed air to anti-blowpipe a6 by hollow shaft a5, compressed air blows to filter core a2 inwall from anti-blowpipe a6 again, the powder that is attached to filter core a2 outer wall will go down from filter core a2 cleaning, simultaneously because many gas holes angled with hollow shaft a5 center are arranged on the anti-blowpipe a6, anti-blowpipe a6 send the compressed-air actuated while under compressed-air actuated reaction force around hollow shaft a5 central rotation, the high pressure gas that anti-blowpipe a6 sends will blowback arrive whole filter core a2, to reach the purpose of the whole filter core a2 of cleaning.
There is following shortcoming in this filter element device: 1) when a plurality of filter element devices are used in combination, filter element device can only be cleared up singly, because industrial production need to guarantee the exhausting system continuous operation, namely a filter element device is in the cleaning state, all the other filter element devices are in the exhausting duty, this manner of cleaning up exhausting amount first mate of system degree when cleaning descends, filter system's exhausting amount when clearing up to three or two filter element device compositions descends about 70% approximately, normal operating conditions impact on system is very large like this, can the first mate reduce qualification rate; 2) this filter element device is when the cleaning state, and same filter core must stop exhausting, and when the exhausting state, same filter core must stop cleaning, and exhausting state and cleaning state can not carry out simultaneously, and the service efficiency of same filter core is low.3) volume is large, takes up room, and cost is high, and the scope of application is limited, and uses dumb.
Summary of the invention
