Description
Technical field
The utility model relates to ventilation filter apparatus fields, and in particular to a kind of bag filter.
Background technique
Bag filter is a kind of equipment for making the gas containing dust obtain net system by packed filter cloth.Usually by
Several filter bags are combined into one group, and several groups are combined into a device.Dusty gas is passed through in filter bag, the grit in gas is trapped on bag,
And the gas exudation purified, it is excluded from exhaust pipe.Using after a certain period of time, by replacing filter bag, filter can be made to restore filtering
Ability.Bag filter pharmacy, automobile and food preparation industry, commercial building ventilating system in be widely used, filter
Efficiency mainly has: thick effect filtering (precision >=5 μm) grade G3(efficiency 85%)；Medium air filtration (precision >=5 μm) grade G4(efficiency
90%), medium air filtration (1-10 μm of precision) grade F5(efficiency 35%)；High-medium efficient filters (1-10 μm of precision) grade F6(efficiency
45%), grade F7(efficiency 65%), grade F8(efficiency 85%) and grade F9(efficiency 95%), have that filter area is big, dust containing capacity
Greatly, the low feature of resistance.
Currently, bag filter structure is relative complex, ontology, filter bag, end socket and dust-extraction unit etc. are generally comprised；Due to
It needs to shut down filter when replacing filter bag with pressure when bag filter works and releases stress, filtering could be opened
Device replaces filter bag, cannot replace online；And the existing filter with dust-extraction unit, usually using mechanical oscillation or compressed gas
Body carries out blowback, and its structure is complicated, while the cleaning effect of filter bag is poor, cannot check the breakage of filter bag in time.
Utility model content
The utility model is intended to overcome prior art defect, and it is simple to provide a kind of structure, is convenient for changing, while can be online
Replacement, without the bag filter for shutting down pressure of releasing.
To achieve the goals above, the technical solution that the utility model is taken is as follows:
A kind of bag filter, including ontology, being slidably connected filter assemblies on the body and is fixedly connected on filtering
The sealing element at component both ends；
The ontology upper end is provided with air inlet, and ontology lower end is provided with exhaust outlet；
Two partitions are provided in the ontology；
The partition is provided centrally with bulkhead through-hole；
Ontology is from top to bottom successively divided into inlet plenum, filter chamber and exhaust chamber by the partition；
The filter chamber two sides are provided with square hole；
The filter assemblies run through filter chamber；
The filter assemblies include filter holder and the filter bag that is fixedly connected on filter holder；
Stepped hole there are two being arranged in parallel on the filter holder；
The filter bag is arranged in stepped hole, and quantity is two or more；
On the outside of the sealing element setting stepped hole；
The sealing element quantity is four or more.
The filter bag quantity is four or more as a further improvement of the utility model, the filter bag in same stepped hole
It is set side by side.
The sealing element quantity is eight or more as a further improvement of the utility model,.
The filter bag surface structure is pleated structure as a further improvement of the utility model,.
Pressure gauge is respectively arranged on the outside of the inlet plenum and exhaust chamber as a further improvement of the utility model,.
Position limiting structure is provided on the filter holder as a further improvement of the utility model,.
Compared with prior art, it is had the beneficial effect that acquired by the utility model:
The utility model is provided with inlet plenum and exhaust chamber before and after filter assemblies, mitigates gas pressure, reduces air-flow pair
The direct impact of filter bag；Using movable filter assemblies, filter assemblies are slidably connected in filter chamber, two on filter assemblies mistake
Filter bag alternately filters, when replacing filter bag, it is only necessary to will cross another clean filter bag and slide among filter chamber, while is to be replaced
Filter bag slides into outer body, realizes the online replacement of filter bag, releases stress without shutting down, and filter bag replacement is simple and convenient, together
When it is convenient for cleaning and check filter bag.
Detailed description of the invention
It is attached that FIG. 1 is a schematic structural view of the utility model；
Attached drawing 2 is the utility model filter assemblies partial structure diagram.
In the accompanying drawings: 1 ontology, 11 partitions, 101 air inlets, 102 inlet plenums, 103 filter chambers, 104 exhaust chambers, 105 exhausts
Mouth, 111 bulkhead through-holes, 112 square holes, 2 filter assemblies, 21 filter holders, 22 filter bags, 201 stepped holes, 3 sealing elements, 4 pressure gauges.
Specific embodiment
Further details of narration is carried out to the utility model below in conjunction with attached drawing.
As shown in Figure 1 and Figure 2, a kind of bag filter, including ontology 1, the filtering group being slidably connected on ontology 1
Part 2 and the sealing element 3 for being fixedly connected on 2 both ends of filter assemblies；1 upper end of ontology is provided with air inlet 101, under ontology 1
End is provided with exhaust outlet 105；There are two partitions 11 for setting in the ontology 1；The partition 11 is provided centrally with bulkhead through-hole
111；Ontology 1 is from top to bottom successively divided into inlet plenum 102, filter chamber 103 and exhaust chamber 104 by the partition 11；The mistake
103 two sides of filter chamber are provided with square hole 112；Pressure gauge 4 is respectively arranged on the outside of the inlet plenum 102 and exhaust chamber 104；The mistake
Filter component 2 includes 22 bracket of filter bag and the filter bag 22 being fixedly connected on filter holder 21；The filter assemblies 2 run through filter chamber
103；Stepped hole 201 there are two being arranged in parallel on the filter holder 21；21 both ends of filter holder are provided with round bump；
The filter bag 22 is arranged in stepped hole 201；22 surface texture of filter bag is pleated structure, and quantity is two；The sealing
The setting of part 3 is in 2 both ends of filter assemblies, 201 outside of stepped hole；3 quantity of sealing element is four.
Utility model works process is as follows:
When filter works normally, air inlet 101, inlet plenum 102,105 structure of filter assemblies 2, exhaust chamber 104 and exhaust outlet
At gas passage, enters inlet plenum 102 from air inlet 101 containing miscellaneous gas and buffer, pass through 22 mistake of filter bag in filter assemblies 2
Impurity is trapped in 22 surface of filter bag by filter, and purification gas enters the buffering of exhaust chamber 104, flows out from exhaust outlet 105.
When impurity is excessive on filter bag 22, the pressure difference of inlet plenum 102 and exhaust chamber 104 outer time pressure gauge 4 increases, and is moved through
Unit is filtered, clean filter bag 22 is slid among filter chamber 103, filter bag 22 to be replaced slides into 1 outside of ontology, while this
Body 1 limits convex block and continues to move to, and filter bag 22 is removed, cleans and checked, after confirmation filter bag 22 can continue to use, reinstalls filtering branch
It is stand-by on frame 21.
Embodiment described above is only the preferred embodiment of the utility model, and the not feasible implementation of the utility model
Exhaustion.For persons skilled in the art, under the premise of without departing substantially from the utility model principle and spirit, it is made
Any obvious change out, should all be contemplated as falling within the claims of the utility model.
