Description

Technical Field

[0001] The utility model relates to the field of bag-type dust collectors, in particular to a dust collector which is convenient for disassembling filter bags. Background Art

[0002] In industrial production processes, dust collectors are important equipment for removing dust and particulate matter from the air. Traditional dust collectors typically use filter bags as filter media, capturing dust in the air through the filter bags to achieve the purpose of purifying the air. However, traditional dust collectors have the following problems during use:

[0003] Difficulty in removing filter bags:

[0004] In traditional dust collectors, filter bags are usually fixed inside the dust collector. Removing and replacing filter bags requires professional tools and a long time, which makes the operation complicated and inefficient.

[0005] The filter bag will accumulate a lot of dust after long-term use, which can easily cause secondary pollution when disassembled, affecting the working environment.

[0006] Inconvenient maintenance:

[0007] Since the filter bags are difficult to remove, the maintenance cycle is long, which increases the downtime of the equipment and affects the continuity and efficiency of production.

[0008] Maintenance personnel need to enter the dust collector when removing the filter bags, which poses certain safety hazards.

[0009] Short service life:

[0010] The traditional fixing method of filter cloth bags is not strong enough and they are prone to loosening or damage after long-term use, which shortens the service life of the filter cloth bags.

[0011] Frequent replacement of filter bags not only increases maintenance costs but also wastes resources.

[0012] Poor sealing:

[0013] Traditional dust collectors have insufficient sealing design between the filter frame and the filter box, which easily leads to dust leakage, affecting the dust removal effect and the cleanliness of the equipment.

[0014] The backflush cleaning system is not perfect:

[0015] Traditional dust collectors may not have an efficient back-blowing cleaning system, or the back-blowing cleaning system may not be designed reasonably enough to effectively remove dust accumulated on the filter bags, affecting the service life and filtering effect of the filter bags.

[0016] Examples of prior art

[0017] Chinese patent publication number CN202010998824.3: discloses a dust collector with a quick disassembly and assembly structure, but the design of its clamping frame and side frame is relatively simple, which fails to completely solve the problem of loose fixation of the filter bag.
