As shown in fig. 1, a sack dust collector, including clean room 1, this clean room 1 is airtight cavity structures, and upper position department is equipped with fixed plate 4 in this clean room 1, and this fixed plate 4 separates this clean room 1 for independent upper chamber 101 and lower cavity 102, several mounting hole has been seted up to the vertical direction of fixed plate 4, is equipped with a connecting sleeve 3 in each mounting hole, fixed mounting has filter bag 2 behind the mounting hole is stretched out to 3 bottoms of connecting sleeve, and filter bag 2 is located lower cavity 102 promptly, and in this embodiment, filter bag 2 sets up for the back taper structure, and filter bag 2 installs on the bag cage, bag cage and 3 fixed connection of connecting sleeve. The inside room end (being the room end of clean room 1) position department of being close to of cavity is equipped with water conservancy diversion component 10 down 102, this water conservancy diversion component 10 is the conical plate structure, water conservancy diversion component 10 is through the even at least three connecting plate fixed connection that sets up of its bottom circumferencial direction on the 1 lateral wall of clean room, 5-10mm clearance is left with lower cavity 102 in this water conservancy diversion component 10 bottom, water conservancy diversion component 10 bottom and lower cavity 102 lateral wall form wide 5-10 mm's annular runner 11 promptly, form the storage space at the bottom of the room that water conservancy diversion component 10 and clean room 1 slope set up. In the process of filtering and dedusting, dust particles such as flour particles, shells, skins and the like in dust are filtered by the filter bag and then enter the storage space through the annular flow passage 11 to be collected. In this embodiment, the sidewall of the upper chamber 101 is provided with an air outlet, and the sidewall of the lower chamber 102 is provided with an air inlet above the flow guiding element 10. The dust mixed gas enters the lower chamber 102 from the gas inlet, dust particles are blocked outside the filter bag 2 after entering the filter bag 2, and clean gas enters the upper chamber 101 through the connecting sleeve 3 after passing through the filter bag 2 and is finally discharged from the gas outlet.

In this embodiment, for improving the quick blanking of the dust granule that adheres to on the filter screen, this device has set up vibrations mechanism, and is concrete, and adapter sleeve 3 slides and sets up in the mounting hole, the mounting hole pore wall inlays and is equipped with sealing washer 5 that corresponds with

adapter sleeve

3, and 3 outer peripheral face tops of adapter sleeve are equipped with the outer eaves that corresponds with the mounting hole, and the setting of outer eaves prevents that adapter sleeve 3 from droing by the mounting hole, and 3 bottom of adapter sleeve are connected jointly on a link 8, cavity 102 is equipped with cam 9 down, and this cam 9 and link 8 bottom surfaces correspond the setting. The axle that cam 9 corresponds stretches out 1 lateral wall of clean room, this axle passes through motor drive, and then drive cam 9 and rotate, along with cam 9 near-end and distal end position alternation, the vibrations of 8 vertical directions of link, and then drive the vibrations of 2 vertical directions of filter bag, through vibrations blanking principle, the dust that adsorbs on filter bag 2 falls to water conservancy diversion component 10 on, because water conservancy diversion component 10 top surface is the conical surface, consequently this dust passes through annular runner 11 and gets into in the storage space and collect, after a period, open the valve row material that sets up on 1 bottom discharging pipe 12 of clean room can.

In order to further prevent the dust particles collected in the storage space from flowing back, a second water inlet pipe 13 is provided in the storage space, and a second nozzle 14 is provided at a position right below the flow guide element 10 on the second water inlet pipe 13. The dust particles in the storage space can be sprayed by the second nozzle 14 at a proper time, so that the dust is moistened, the weight of the dust is increased, and the dust is prevented from flowing back.

In this embodiment, in order to prevent the filter bag 2 from being blocked by the powder particles after long-time operation, a spraying mechanism is arranged in the upper chamber 101, the spraying mechanism includes a first water inlet pipe 6, and the first water inlet pipe 6 is provided with a plurality of first nozzles 7 corresponding to one connecting sleeve 3. The structure is a back washing structure, namely the interior of the filter bag 2 is sprayed through the first nozzle 7, and when high-pressure water flows out of the filter bag 2, dust adhered to the outer surface of the filter bag 2 can be washed and cleaned, so that the filtering function of the filter bag 2 is improved.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, so that any modifications, equivalents, improvements and the like, which are within the spirit and principle of the present invention, should be included in the scope of the present invention.
