Description
Technical field
The present invention relates to art of filters, particularly a kind of filter disc structure of laminated filter, for the various impurity in filter medium.
Background technology
Filter is generally divided into well strainer and laminated filter two kinds.Conventional filter is generally stainless steel well strainer, and be both surface filtration, water environment capacity is poor, and the life-span is short, and in addition when filter medium is severe corrosive, stainless steel material easily reacts and do not meet the demands.When being particularly applied in space industry, the well strainer of prior art with the severe corrosive oxidant reaction in satellite bipropellant propulsion system, and can be discontented with the long-life instructions for use of foot.Therefore, need that a kind of water environment capacity is strong, flow resistance is low, long-life and the strong filter of corrosion resistance.
Summary of the invention
The technical problem to be solved in the present invention is: the structural design providing a kind of filter, is applicable to receive by force dirt, low flow resistance, long-life, and the operating mode that corrosion resistance is strong.
Technical scheme of the present invention is: the filter disc structure designing a kind of laminated filter, filter disc has groove, after the superposition of multi-disc filter disc, forms circulation passage between groove and adjacent pads; The profile design of filter disc, for having multiple petal branch, each petal branch has multiple groove.
Further, the trend of multiple groove is towards the center of petal branch.
Further, filter disc is titanium system.
Further, filter disc is made up of the titanium foil that 0.06mm is thick.
Further, filter disc is processed as the shape with petal branch by low-speed WEDM.
Further, the groove of filter surface is by carrying out the formation of hydrofluoric acid chemical etching on titanium foil surface.
The present invention's advantage is compared with prior art:
(1) by the petal design of filter disc, design multiple branch, and increase circulation passage as much as possible, make circulation passage towards petal center simultaneously, make filter possess low flow resistance, receive dirty ability by force, possess good structural strength simultaneously.
(2) pure titanium system, possesses stronger corrosion resistance.
(3) filtering accuracy can change arbitrarily, can manufacture high-precision filter.
(4) filter surface crudy is high, and filter disc edge-light cleanliness reaches more than Ra0.4, not easily produces fifth wheel.
Accompanying drawing explanation
Fig. 1 shows the schematic diagram of the laminated filter in the present invention;
Fig. 2 shows the filter disc structural representation of the laminated filter in the present invention.
Detailed description of the invention
In laminated filter, lamination is impurity treatment carrier, and form by the filter disc 10 of some tracts of one-side band different directions grooves is superimposed, the groove 20 between filter disc 10 on adjacent surface forms circulation passage, and the impurity in medium is intercepted at outside individual channel.Work principle of filter schematic diagram as shown in Figure 1.
Because laminated filter mainly relies on the groove 20 on filter disc 10 to filter, the etching depth of groove 20 determines the filtering accuracy of filter; The quantity of groove 20 and trend determine flow pressure drop ability, the water environment capacity of filter.Therefore the filter disc structural design of laminated filter is the core technology of design for filtration elements, has direct impact to the filtering accuracy of filter, water environment capacity, flow pressure drop ability.
The filter filter disc of the present invention's design, the titanium foil thick by 0.06mm is made, take filter capacity, filter efficiency into consideration and possess certain intensity, not easily lose in processing transport process, devise a kind of satisfied design needs, be easy to the filter disc version of process and assemble, in the volume situation as far as possible reducing filter, increase the surface area of filter core, make to be maximized by the passage of filter core, increase the water environment capacity of filter, reduce filter's flow pressure drop simultaneously.
The structural representation of filter disc as shown in Figure 2, filter disc comprises centre bore and filter disc structure.Filter disc structural design is the similar petal branch with multiple expansion, such as, stretches out branch in clockwise 0 °, 45 °, 90 °, 135 °, 180 °, 225 °, 270 °, 315 ° eight directions of filter disc 10.Each petal branch forms multiple groove 20, the trend of each groove 20 towards the center of petal branch belonging to separately, multiple grooves of a petal branch side move towards parallel.Such trench design is conducive to reducing flow resistance.Titanium foil filter disc, by low-speed WEDM, is processed as above-mentioned shape, ensures that filter disc outer surface possesses sufficiently high fineness simultaneously.Be designed to above-mentioned flower pattern, can increase the surface area of filter disc, the circulation area making same cross-sectional amass situation lower filter maximizes.
The trench flow circulation passage of filter surface, by carrying out hydrofluoric acid chemical etching to be formed on titanium foil surface, forming above-mentioned shape, being easy to medium and flowing through filter from outside to inside, reduces the flow resistance of filter.In addition, according to mission requirements, can etch the filter disc of any degree of depth, such as, existing filter disc gash depth is the matured product of 15 μm, 20 μm, 30 μm at present.
The present invention compared with prior art beneficial effect is:
1. by the petal design of filter disc, increase circulation passage as much as possible, make circulation passage towards petal center simultaneously, make filter possess low flow resistance, receive dirty ability by force, possess good structural strength simultaneously.
Laminated filter adopts gap filter type, and the control of filtering accuracy and overall structure are innovation difficult points.The corrosion depth of filter groove is depended in the control of filtering accuracy, and therefore the degree of depth of groove and trend are the keys of design for filtration elements.
Filter disc structural design in this paper have employed and meets design needs and the version being easy to process and assemble.Novel and reasonable structure, ensure that the success of the program.Meanwhile, this kind of design can improve the surface channel of filter, strengthens water environment capacity, and reduces flow pressure drop, improves service life.
2. pure titanium system, possesses stronger corrosion resistance.
The material of filter disc is pure titanium, has good compatibility, be applicable to long-lived operation with strong corrosive media, and the metallic particles avoiding stainless steel well strainer and strong corrosive media to react producing and jelly take system downstream to.Can be compatible with the severe corrosive oxidant in Space radiation.
3. any filtering accuracy, can manufacture high-precision filter
Filtering accuracy can change according to the etching depth of filter disc, is applicable to high-precision filtration, at present according to demand, devises the matured product of 15 μm, 20 μm, 30 μm three kinds of filtering accuracies, the follow-up product that can design other any filtering accuracy as required.
According to installation principle as shown in Figure 1, the filter disc structure multi-disc shown in Fig. 2 is stacked together, forms the filter core of filter.According to this assembling form, devise the matured product of 15 μm, 20 μm, 30 μm three kinds of filtering accuracies at present.
4. filter surface crudy is high, and filter disc edge-light cleanliness reaches more than Ra0.4, not easily produces fifth wheel.
Filter disc processing adopts the mode of low-speed WEDM, ensures the shape being processed as the petal branch met design requirement, and ensures that filter disc edge possesses higher fineness simultaneously, avoids follow-up generation fifth wheel.
