Description
Technical field
The utility model relates to filter core, especially a kind of anti-fracture powder sintered filter core.
Background technique
Filter be widely used in the industries such as chemical industry, oil refining, pharmacy, water process, medicine and it is other need it is solid to air inlet,
Liquid consolidates or the industry of Liquid liquid Separation filtering, currently, filter core used in filter is mainly powder sintered filter core, powder sintered pipe
It is that high temperature sintering forms after being suppressed by powder by mold, each step production technology of strict control has high mechanical strength, resistance to height
The characteristics of temperature, corrosion resistance and good, even aperture distribution, good permeability, by adjusting powder particle size and manufacture craft, from
And produce that accuracy rating is wider, the porous metals sintered filter core of external form complexity.But due to the thermal expansion of powder metallurgy part,
The influence of the factors such as the oxide or impurity that are mingled in harden ability, hole makes powder filter pipe show higher brittleness, especially
Be used in environment it is relatively severe in the case where, the temperature stress accumulated when by weld seam welding stress, sintering, especially powder is burnt
Knot filter core is influenced by fluid impact at work, is tended to that powder sintered filter core is caused transversal crack occur, is gone out when serious
Existing whole branch filter core fracture is fallen.There are a large amount of material leakages in fracture in less serious case after filter core fracture, keeps entire process system abnormal, if filter
Core is mounted in the roof scrubber above reaction kettle, the filter core remains fallen are fallen into reactor cause to save after
Fruit.Therefore, the improvement and innovation of powder sintered filter core are imperative.
Utility model content
For above situation, for the defect for overcoming the prior art, the purpose of the utility model is to provide a kind of anti-fracture powder
Last sintered filter core can effectively solve the problems, such as that existing powder sintered filter core brittleness is high, be easy to appear transversal crack and fracture is fallen.
The technical solution that the utility model solves is a kind of anti-fracture powder sintered filter core, including filter cartridge, filter core cylinder
Body both ends are respectively provided with the first fixing piece and the second fixing piece, and Y shape pull rod, the Y shape pull rod are housed inside the filter cartridge
Separated end be fixed on the first fixing piece, the other end through connecting screw head pass through the second fixing piece, protrude into the second fixing piece end
In portion's groove, it is fixed on the second fixing piece by nut.
The utility model structure is simple, and novel and unique, design is scientific and reasonable, manufacture easy to produce, at low cost, easily promotes and answers
With long service life, using effect is good, and anti-adverse environment is strong, can effectively solve existing powder sintered filter core brittleness height, be easy
The problem of existing transversal crack and fracture are fallen, is the innovation on filter element, economic and social benefit is significant.
Detailed description of the invention
Fig. 1 is the structural front view of the utility model.
Specific embodiment
It elaborates below in conjunction with attached drawing and particular condition in use to specific embodiment of the present utility model.
As shown in Figure 1, a kind of anti-fracture powder sintered filter core of the utility model, including filter cartridge 2,2 liang of filter cartridge
End is respectively provided with the first fixing piece 1 and the second fixing piece 4, and Y shape pull rod 3, the Y shape pull rod 3 are housed inside the filter cartridge 2
Separated end be fixed on the first fixing piece 1, the other end through connecting screw head 8 pass through the second fixing piece 4, protrude into the second fixing piece
In 4 end grooves 5, it is fixed on the second fixing piece 4 by nut 7.
In order to guarantee using effect and easy to use,
The filter cartridge 2 be by powder of stainless steel or Monel monel it is powder sintered at hollow circle.
First fixing piece 1 be with the concentric hollow body of filter cartridge 2, outer wall be in rotary table scalariform 9.
Second fixing piece 4 is the seal that there is circular groove in outer end, and sealing circular groove is housed on external end head
Round dististyle 6.
Applicant is it is noted that the above-mentioned specific implementation for being only embodiment, being for illustrating the utility model provided
Mode, rather than for limiting scope of protection of the utility model, it is all take made by equivalent equivalent substitution technological means
Technical solution substantially identical with technical solutions of the utility model, belongs to the protection scope of the utility model.
The utility model is directed to the various unstability of powder sintered pipe, using the fixing piece at the fixed both ends of connector, increases
Strong whole intensity, while also guaranteeing that the weld seam of filter cartridge in harsh environment goes wrong rear connectors force guarantee system
Normal operation, the not overall operation of breaking space reduces loss.
The utility model does not influence the normal filtration or blowback effect of system, and the nut of connector bottom is according to calculating
It is fixed using torque spanner, guarantees filter core uniformity and reliability.
By above structure it is found that the utility model has following advantageous effects:
1. stability is strong: after guaranteeing welding seam breaking, fixing piece be will not fall off, and not influence system operation；
2. intensity is high: connector connects upper and lower fixing piece, on the one hand improves the integral strength of filter core, increases powder and burns
The impact strength for tying filter core reduces the probability that powder sintered filter core crackle occurs, on the other hand in powder sintered filter core contingency
After cracked, directly filter core is avoided phenomenon of rupture occur, has prevented filter core because of the large area material leakage of fracture appearance and because of fracture
Remains are fallen and the even more serious consequence that occurs.
3. operability is high: being linked using pull rod connector, good to operate, no added others equipment, advantages of simple uses
Effect is good；
In short, the utility model structure is simple, novel and unique counts scientific and reasonable, manufacture easy to produce, at low cost, easily promotes
Using, can be widely applied to the fields such as petrochemical industry, nuclear industry, national defense industry, long service life, using effect is good, effectively solve
Certainly powder tube welding is unstable, is the innovation on filter element the problem of being easily broken off, can not remedy after fracture, it is economical and
Social benefit is significant.
