Abstract

The utility model relates to a disassemble ultrafilter bag for dust collectors, which is composed of a filter bag and interface connection components. The utility model is characterized in that the filter bag is scald made of sub-high efficiency filter materials which are easy to be welded, the lining is permeable paper, and a neck bag opening is arranged at one end of the filter bag; the interface connection components are composed of a ring fixing object on the barrel wall, a tubular connector which is slightly tapered, and a ring-shaped fastening cover which is provided with threads; the neck bag opening of the filter bag is tightly clamped by the ring fixing object and the tubular connector, and is tightly locked by the fastening cover. The utility model can be used for thoroughly clearing sprayed dust, the dust collecting barrel is clean, and the rubbish dumping and the filter cleaning are avoided. The utility model is suitable for various medium-sized and small-sized dust collectors.

Description

Disassemble ultrafilter bag for dust collector

The utility model relates to the filter bag that a kind of dust catcher part, particularly dust catcher are used.

The most general a kind of dust collection manner of normal domestic use dust catcher is to be provided with one deck flannelette between its dust bucket and power section, the grit rubbish that is inhaled into is filtered detention in bucket by flannelette, one of shortcoming is to use certain hour also to pat, to clean flannelette, the thing that the person of being to use is unwilling to do by the interior rubbish of clear bucket.So being changed, flannelette does pouch, dust rubbish is collected in the bag, from bag, pour out again, one of this mode shortcoming is, dust bag advance the dirt sack also in bucket, promptly link with a bucket wall in the wall inboard of bucket, because in the whole dust bucket and all be to be in high vacuum in the dust bag, when the grit that sucks in when hose reaches dust bag and advances the dirt sack, sucked in the bag by powerful negative pressure on the one hand, be inhaled in the bucket from the slit between dust bag and bucket wall on the one hand, both polluted sack outer surface and bucket inwall, also discharged, polluted the interior space from exhaust outlet.

Flannelette or the shortcoming of slightly imitating the dust bag of filter paper be, and be all too low to the filter efficiency of tiny grit, has only a few percent.

Dust catcher of the present utility model is with the purpose of detachable ultra-clean filter bag, exactly with can be tiny grit overwhelming majority ultra-clean filter bag of getting off of detention all, replace most tiny grits can both see through flannelette and the common filter bag that goes, with a kind of new interface coupling assembly, the sack of dust bag is located at outside the wall of bucket, fundamentally to solve the dirt problem of leaking.

Dust catcher of the present utility model is made up of filter bag and interface coupling assembling with detachable ultra-clean filter bag, it is characterized in that, scalds the filter bag of making by the inferior efficient filtrate that easily scalds weldering, and the liner air-permeable paper is established a neck sack at the one end; The interface coupling assembling is by the ring-type fixed body on the bucket wall, slightly the tubulose connector of tapering and the threaded fastening cover of ring-type are formed.Between ring-type fixed body and the tubulose connector, clamp the neck sack of filter bag, lock with fastening cover.

Using method of the present utility model is, earlier fixed body is fixed on the wall of dust bucket, and the neck sack of filter bag is stretched out fixed body, rely on the tubulose connector of band tapering, the filter bag jam-packed between fixed body and tubulose connector, is tightened fastening cover, connector is locked.Sack is in contact with it the slit and all stays the bucket outside like this, be under the room atmosphere pressure, even thereby leak, also only allow room air to advance in the bucket, and can not make the grit in the hose drain to the indoor of malleation along the slit by slit source.

One of advantage of the present utility model is a spray dirt of having removed the harm people, can get off the detention of the above grit overwhelming majority of 0.5 μ m.

Through entrusting national air-conditioning equipment quality testing center formally to measure and flannelette filters and to be compared as follows:

The transmitance %(efficient % of various particle diameter grits)

	≥0.5μm	≥1μm	≥2μm	≥5μm	≥10μm
						Detachable ultra-clean filter bag of the present utility model	0.9 (99.1)	0.05 (99.95)	0 (100)	0 (100)	0 (100)
The flannelette that present common dust catcher generally uses filters	97.3 (2.7)	66.2 (33.8)	17.7 (80.3)	4.2 (95.8)	1.3 (98.7)

As seen for the above grit of 1 μ m of tool harmfulness, detachable ultra-clean filter bag all detention gets off, and flannelette filters then will be through 2/3; For the above grit of 0.5 μ m; The former only sees through 1%, and the latter then almost all sees through.

Two of advantage of the present utility model is neat and tidy in the dust bucket after the dust suction, again need not fall native cask washing.

Three of advantage is dust catchers that the utility model both had been applicable to new production, also is applicable to the repacking of old dust catcher, both can only adorn a filter bag simply and deal with problems, and also can mix the interface coupling assembly and use.

Reduced form of the present utility model is that a filter bag compresses the jam-packed structure with representing the sack that is coated with adhesive sticker of coupling assembly or being stained with the sack of hard paper and the wedge-shaped slot on the bucket wall etc.The adhesive sticker protection sheet of tearing is affixed on a barrel wall interface to sack, or in the hard paper insertion groove, compresses jam-packed and get final product.

Below in conjunction with drawings and Examples, the utility model is described further.

Fig. 1 is that the utility model is used for old dust catcher repacking, makes situation about being screwed.

Fig. 2 is that the utility model is used for new dust catcher production, and fixed body and bucket wall are done together situation.

As seen from the figure, dust catcher is made up of filter bag 1 and interface coupling assembling 2 with detachable ultra-clean filter bag, it is characterized in that, scalds the filter bag of making 1 by the inferior efficient filtrate that easily scalds weldering, and liner air-permeable paper 3 is established a neck sack 4 at the one end; Interface coupling assembling 2 is by the ring-type fixed body 5 on the bucket wall, slightly the tubulose connector 6 of tapering and the threaded fastening cover 7 of ring-type are formed.Fixed body among Fig. 1 is fixed on barrel wall 9 by tapping screw 8.Fixed body among Fig. 2 is to stick with glue to be fixed on barrel wall.

Claims

1, a kind of dust catcher is made up of filter bag and interface coupling assembling with detachable ultra-clean filter bag, it is characterized in that, scalds the filter bag of making by the inferior efficient filtrate that easily scalds weldering, and the liner air-permeable paper is established a neck sack at the one end; The interface coupling assembling is by the ring-type fixed body on the bucket wall, slightly the tubulose connector of tapering and the threaded fastening cover of ring-type are formed; Between ring-type fixed body and the tubulose connector, clamp the neck sack of filter bag, lock with fastening cover.
