Abstract
The utility model relates to a dust remover field, concretely relates to bag collector sack seal structure, it is including installing at the packing 5 of the chuck on 1 top on the filter bag skeleton of dust remover 3, welding card steel ring 7 and the cover on the card of dust remover 2 at 4 oral areas of filter bag, the higher authorities of chuck 3 are provided with turn -ups 6, the outside diameter of turn -ups 6 is greater than the diameter of card steel ring 7, the sack is sealed when only needing the preparation skeleton, make the turn down rims high summary of chuck be less than filter bag packing 5 the height can, including turn down rims size just in time covers packing and card steel ring, moreover the turn -ups to the card still kept certain distance, through the action of gravity of filter bag skeleton and chuck, compress tightly chuck for the packing to reach sealed effect, both convenient the maintenance was changed, and the cost is also low.
Description
Technical field
This utility model relates to a kind of sack cleaner bag mouth and seals structure.
Background technology
At present, present stage filter bag and the seal form sealing main employing draw-in groove packing of cleaner unit, by being arranged on the elastic expansion circle of filter bag opening, filter bag is stuck on card hole.But the pulsed jet cloth filter filter bag built in early days and seal form many employings side seals of cleaner unit, be i.e. welded with steel ring on bag filter tubesheet hole, filter bag opening packing side seals with steel ring contact internal walls.This sealing initial performances is the best, but cleaner unit is after long-time use, and steel ring base there will be irregular deformation, and it is widely different that internal diameter becomes, and causes packing to be difficult to completely and steel ring seals, cause dust side leakage.
If retaining card steel ring, changing filter bag, changing the form of draw-in groove expansion ring seale into, due to Wheel Rim deformation, part steel ring is the nearest with edge, card hole, can withstand bag head and packing can not be flicked completely.If removing card steel ring, change bag filter tubesheet and filter bag, then transformation difficulty is big, costly.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of sack cleaner bag mouth improving sealing at filter pocket mouths and seals structure.
This utility model adopts the following technical scheme that
A kind of sack cleaner bag mouth seals structure, it includes the chuck being arranged on the Filter-bag carcass top of cleaner unit, be welded on the card of cleaner unit card steel ring and the packing being enclosed within filter pocket mouth, the top of described chuck is provided with the flange of Semi surrounding type, described packing card is embedded in the inner side of described card steel ring, and the maximum inner diameter of described flange is 1.2 times of card steel ring diameter.
Improve further as this utility model, the height h of described flange 60Height h for described packing 51Computing formula be h0=h1-2mm, deviation (+0 ,-1) mm.
Good effect of the present utility model is as follows:
This utility model simple in construction, bag mouth seals and makes the height of chuck flange be slightly less than the height of filter bag packing 5 when only need to make skeleton, including packing and card steel ring are just covered by the size of described flange, and flange also maintains a certain distance to card, by Filter-bag carcass and and the action of gravity of chuck, packing chuck is compressed, thus reaches the effect sealed, both convenient maintenance was changed, and cost is the lowest.
Accompanying drawing explanation
Accompanying drawing 1 is this utility model structural representation.
In the accompanying drawings: 1-Filter-bag carcass, 2-card, 3-chuck, 4-filter bag, 5-packing, 6-flange, 7-card steel ring, h0-chuck flange width, h1-filter bag opening packing width.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
A kind of sack cleaner bag mouth as shown in Figure 1 seals structure, it chuck 3 including being arranged on Filter-bag carcass 1 top of cleaner unit, the card steel ring 7 being welded on the card 2 of cleaner unit and the packing 5 being enclosed within filter bag 4 oral area, packing 5 is enclosed within the oral area of filter bag 4, rely on the elasticity of packing 5, closely cooperate with the card steel ring 7 being welded on card 2, filter bag 4 is compressed, prevent the leakage of filter bag 4 oral area or come off, then the Filter-bag carcass 1 with chuck 3 is loaded in filter bag 4, because the top of described chuck 3 is provided with flange 6, the maximum inner diameter of described flange (6) is 1.2 times of card steel ring (7) diameter, described flange 6 is under the action of gravity of Filter-bag carcass 1 and chuck 3, packing 5 is tightly pressed at the tightness further adding sealing on card 2.
In order to make sealing obtain bigger lifting, it is computed obtaining with multiple authentication, the height h of described flange 60Height h for described packing 51Computing formula be h0= h1-2mm, deviation (+0,-1) mm, now because of flange distance card 2, there is a certain distance, so both ensure that flange 6 bumped to card 2 in the course of the work, causing poorly sealed, filter bag 4 dust side leakage, again will not be relatively big because turning over the distance all over 6 distance cards, cause the instability of Filter-bag carcass 1, increase the probability of dust side leakage.
Claims (2)
1. a sack cleaner bag mouth seals structure, it includes the chuck (3) being arranged on Filter-bag carcass (1) top of cleaner unit, be welded on the card (2) of cleaner unit card steel ring (7) and the packing (5) being enclosed within filter bag (4) oral area, it is characterized in that: the top of described chuck (3) is provided with the flange (6) of Semi surrounding type, described packing (5) card is embedded in the inner side of described card steel ring (7), and the maximum inner diameter of described flange (6) is 1.2 times of card steel ring (7) diameter.
A kind of sack cleaner bag mouth the most according to claim 1 seals structure, it is characterised in that: the height h of described flange (6)0Height h for described packing (5)1Computing formula be h0= h1-2mm。
