Description

A kind of bag filter
Technical field
The utility model relates to a kind of industrial dedusting field, in particular to a kind of bag filter.
Background technique
Bag filter is a kind of dry type dust filtration device, it is suitable for trapping tiny, dry, non-fiber dust.Filter bag Using the filter cloth or nonwoven felt of weaving at being filtered using the filtration of fabric to dusty gas, when containing After dust and gas body enters bag filter, particle is big, heavy dust falls into ash bucket, contain since the effect of gravity settles down There is the gas of relatively fine dust when passing through filter cloth, dust is purified gas by detention.
The existing Chinese patent that can refer to application No. is 201711436723.6, it discloses one kind with auxiliary vibration The bag filter of structure, including bag filter ontology, bag filter ontology include dust-extraction unit, shaking device and powder Dirt collecting bin, bag filter ontology are internally provided with baffle, and there are two baffle plate settings, and two baffles are connected to bag-type dust On the inner wall of device ontology, it is provided with ventilation opening in the plate face of baffle, is provided with fixation hole on the outside of ventilation opening, is set between two baffles Be equipped with dust-extraction unit, dust-extraction unit is matched with ventilation opening, dust-extraction unit include filter plate, support frame, fixing seat, sunpender and Filter bag, filter plate are connected to the top of support frame, and vibration device is arranged on bag filter ontology, compared to traditional cloth bag Deduster, shaking device are rotated under the driving of shaft, and are struck by striking block to the dust-extraction unit of two sides, are made The dust for being adsorbed on filter bag inner wall falls.
Above-mentioned bag filter can be shaken off the dust on filter bag by shock structure, and efficiency of dust collection is improved.But Due to bag filter average physique is larger, height it is higher, when filter bag when something goes wrong, need manually to climb by tools such as ladders It climbs to the top of bag filter and is checked and replaced, staff is inconvenient, and there are security risks.
Utility model content
In view of the deficienciess of the prior art, reaching and being convenient for the purpose of the utility model is to provide a kind of bag filter Replace the effect of filter bag.
The above-mentioned technical purpose of the utility model has the technical scheme that
