Description
Technical field
The utility model relates to industrial dedusting equipment technical fields, more particularly to a kind of high service life bag-type dust
Device.
Background technique
Sack cleaner is a kind of dry type dust filtration device.Filter bag is using the filter cloth or nonwoven felt of weaving at utilization
The filtration of fabric is filtered dusty gas, and after dusty gas enters sack cleaner, particle is big, than great
Dust settled down due to the effect of gravity, fall into ash bucket, the gas containing relatively fine dust is when passing through filtrate, dust quilt
Detention is purified gas.
Separation of the card of bag filter as dust catcher gas purifying chamber and filter chamber, for hanging dedusting filtering bag component,
Simultaneously by the inspection platform as filter bag of dust collector component.Existing bag filter card is process by punching machine,
Card during punching machine punching, have may in card bottom there are some burrs, cloth bag is being installed to cloth in this way
When inside bag dust collector, the burr of card may scratch cloth bag impaired.Cloth bag is the core of bag filter, and cloth bag is once
It is impaired, the efficiency and service life of the bag filter substantially reduced.
Utility model content
The shortcomings that technical problem to be solved in the utility model is, overcomes the prior art provides a kind of high service life
Bag filter.
In order to solve the above technical problems, the technical solution of the utility model is as follows:
A kind of high service life bag filter, including bag filter tubesheet, if being uniformly provided on the bag filter tubesheet
A through-hole one is done, matcoveredn is set on the lower end surface of the bag filter tubesheet, corresponds at through-hole one on the protective layer and opens
It is located at through-hole two equipped with through-hole two, on the protective layer and is provided with cylindric protective case, the lower end of the protective case and through-hole
Two are connected, and the upper end of the protective case extends in through-hole one and the side of the protective case fits with one inner sidewall of through-hole.
Further, the edge of protective layer is provided with threaded hole one, corresponds at threaded hole one on bag filter tubesheet and sets
It is equipped with threaded hole two, is provided with bolt in threaded hole one and threaded hole two.
Preceding a kind of high service life bag filter, if several through-holes one are evenly arranged on bag filter tubesheet
Dry to arrange, any one through-hole one in any one row is located at the perpendicular bisector of two neighboring one line of centres of through-hole in an adjacent row
On.
The thickness of a kind of preceding high service life bag filter, protective layer and protective case is 5mm.
The beneficial effects of the utility model are:
(1) the utility model installs matcoveredn on the lower end surface of bag filter tubesheet, corresponds to through-hole one on protective layer
Place is provided with cylindric protective case, and when installing cloth bag, protective layer and cylindric protective case can separate bag filter tubesheet and cloth bag
It opens, contacts cloth bag directly with bag filter tubesheet, so that the burr on bag filter tubesheet be avoided to scratch cloth bag, ensure that cloth bag
The dust removing effects of deduster extend the service life of cloth bag；
(2) threaded hole one and threaded hole are opened up respectively in the edge of protective layer and bag filter tubesheet in the utility model
Two, bolt need to be only installed when installing protective layer in threaded hole one and threaded hole two, easy for installation and protective layer with remove
Dirt device card stable connection；
(3) through-hole one on bag filter tubesheet is staggered in the utility model, so that cloth bag be made to be staggered, is increased
The spacing of cloth bag transverse radial, reduces gas velocity, so that the filter effect of cloth bag is improved, meanwhile, it is effectively prevented from
The mutual collision friction of cloth bag and cloth bag bottom, further extends the service life of cloth bag；
(4) thickness of protective layer and protective case is 5mm in the utility model, not only ensure that bag filter tubesheet with
The segregation of cloth bag, and will not influence the normal mounting of cloth bag.

Specific embodiment
To make the content of the utility model be easier to be clearly understood, below according to specific embodiment and combine attached
Figure, makes further details of explanation to the utility model.
A kind of high service life bag filter is present embodiments provided, as shown in Figure 1-3, include bag filter tubesheet 1.?
Five exhausting holes 1 are uniformly provided on bag filter tubesheet 1, the adjacent mutual Heterogeneous Permutation of two rows, that is, appoint in this five exhausting hole 1
Any one through-hole 1 anticipated in a row is located in an adjacent row on the perpendicular bisector of two neighboring one 2 line of centres of through-hole.
Matcoveredn 3 is installed on the lower end surface of bag filter tubesheet 1.It is opened up in four edges of bag filter tubesheet 1
There is threaded hole 1, the position on protective layer 3 corresponding to threaded hole 1 offers threaded hole 27.When installing protective layer 3,
The threaded hole 27 on protective layer 3 need to be only aligned with the threaded hole 1 on bag filter tubesheet 1, then bolt is installed.?
Position on protective layer 3 corresponding to through-hole 1 offers through-hole 24, and the diameter of through-hole 24 is slightly less than the diameter of through-hole 1.
A cylindric protective case 5 is provided at each through-hole 24, the lower end of protective case 5 is docked with through-hole 24, i.e. protective case 5
The periphery of lower end surface is docked with the circumference of through-hole 24, and the upper end of protective case 5 extends in through-hole 1 and the side of protective case 5 and logical
One 2 inner sidewall of hole fits, and the outer diameter of 5 cross section of protective case is equal to the internal diameter of through-hole 1.
Wherein, the thickness of protective layer 3 and protective case 5 is 5mm.
It is described as follows: during installation, first by the threaded hole on the threaded hole 27 and bag filter tubesheet 1 on protective layer 3
1 alignment, then bolt is installed, protective layer 3 is mounted on bag filter tubesheet 1, at this point, the through-hole 24 on protective layer 3 with remove
Through-hole 1 on dirt device card 1 is corresponding, and the protective case 5 on protective layer 3 extends in through-hole 1, and the side of protective case 5 is tight
On the close inner sidewall for being fitted in through-hole 1.Then cloth bag is mounted on bag filter tubesheet 1 again, at this point, protective layer 3 and guarantor
Sheath 5 can separate bag filter tubesheet 1 with cloth bag, avoid the burr on bag filter tubesheet 1 from scratching cloth bag, ensure that cloth bag removes
The dust removing effects of dirt device extend the service life of cloth bag.
In addition to the implementation, the utility model can also have other embodiments；It is all to use equivalent replacement or equivalent change
The technical solution to be formed is changed, the protection scope of the requires of the utility model is all fallen within.
