Description
Technical field
The utility model relates to a kind of deduster auxiliary facility, is specifically related to a kind of filter bag fixing device of duct collector.
Background technology
The capital equipment of the flue gas that in environmental protection industry (epi), sack cleaner is all kinds of boiler of process, incinerator produces when burning.Deduster body construction is roughly divided into ash bucket, blast pipe, raising middle flask, top box, discharge pipe, bypass airduct, injection tube, filter etc., its concrete principle is: flue gas is under blower negative pressure, enter in ash bucket through air inlet main pipe and air intake short tube, under meal dirt falls into ash bucket, fine dust rises in raising middle flask with air-flow, overworks filter cloth in raising middle flask, and air-flow enters upper box through filter cloth, until discharge pipe, dust removal process terminates.
Sack cleaner essential core position is filter, horizontal card is provided with in sack cleaner upper box, long filter evenly hangs over (length of sack cleaner filter can design according to actual requirement) in card hole respectively, filter bag is longer, require higher to the flatness of card and the perpendicularity of filter cage bone, not so can overlap at the bottom of filter bag.And reality always can not reach required flatness and perpendicularity, be difficult to ensure that filter bag is not overlapping, under the effect of the air-flow that overlapping cloth bag rises at flue gas, constantly rock, constantly rub each other, finally cause broken bag.Device for fixing filter bag is the device solving above technical problem, and it significantly can increase filter bag of dust collector service life, reduces deduster maintenance probability.
Utility model content
For solving the problem, the utility model discloses a kind of filter bag fixing device of duct collector, the filter bag that can solve in deduster collides with each other in the course of the work, rubs mutually, filter bag distortion, the problem such as to ventilate not smooth.
A kind of filter bag fixing device of duct collector, comprise filter bag, filter bag support is provided with in described filter bag, described filter bag support is for supporting filter bag, described filter bag support comprises upper ring body, lower body and montant, described montant connects upper ring body and lower body, through hole is provided with bottom described lower body, described lower body is bolted on dividing plate, described bolt comprises head and screw rod, the head diameter of described bolt is greater than the diameter of through hole, the end of described screw rod is inserted in dividing plate through through hole and filter bag, described dividing plate offers the circular hole matched with screw rod end, fixed by screw bolt and nut bottom described filter bag.
As further improvement of the utility model, between described screw bolt and nut, be provided with pad.
As further improvement of the utility model, the material of described pad is rubber.
Compared with prior art, the utility model tool has the following advantages and beneficial effect: structure is simple, be applicable to filter bag length is greater than on the deduster of 6m, can reduce because of the broken bag phenomenon caused that rubs at the bottom of bag, extend filter bag replacing construction, reduce user's maintenance operation cost.The end of screw rod is not fixed, and while ensure that filter bag is fixing, also can have rocking to a certain degree, be very beneficial for the dedusting on filter bag surface.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of filter bag and support in the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, following detailed description of the invention should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometric center respectively.
As shown in the figure, a kind of filter bag fixing device of duct collector, comprise filter bag 1, filter bag support 2 is provided with in filter bag 1, filter bag support 2 is for supporting filter bag 1, and filter bag support 2 comprises upper ring body 21, lower body 22 and montant 23, and lower body 22 is closed, lower body and upper ring body be arranged in parallel, and the shape of lower body is identical with the shape of pressed on ring.Connected by montant 23 between upper ring body 21 and lower body 22, upper ring body 21, montant 23 and lower body 22 be a composition cage body jointly, the middle part of cage body can also be provided with the reinforcing ring playing reinforcement effect, reinforcing ring and upper ring body 21 be arranged in parallel, and the shape of reinforcing ring is identical with the shape of upper ring body 21.Through hole is provided with in the bottom of lower body 22, lower body 22 is fixed on dividing plate 5 by bolt 4, bolt 4 comprises head 41 and screw rod 42, head 41 diameter of bolt is greater than the diameter of through hole, the end of screw rod 42 is inserted in dividing plate 5 through through hole and filter bag 1, the end of screw rod is through dividing plate 5, fixed by bolt 4 and nut 7 bottom filter bag, in order to not affect the sealing bottom filter bag, reduce nuts and bolt to the wearing and tearing bottom filter bag, pad 6 is provided with bottom filter bag 1, preferred rubber pad, there is certain cushioning effect, reduce the wearing and tearing bottom filter bag, dividing plate 5 offers the circular hole 3 matched with screw rod 42 end, the aperture of circular hole 3 is greater than the diameter of screw rod 42 end slightly, the activity space that screw rod is certain can be given, while guarantee filter bag is fixing, also rocking to a certain degree can be had, be very beneficial for the dedusting on filter bag surface.
The above; it is only preferred embodiment of the present utility model; not restriction the utility model being made to any other form, and any amendment done according to technical spirit of the present utility model or equivalent variations, still belong to the utility model scope required for protection.
