Abstract
A kind of high pressure backwashing filter core, comprise stiffener assembly and filter screen device, described filter screen device is wedge shaped filter net, and described stiffener assembly ecto-entad comprises outer annular-stiffer muscle, outer straight line muscle, interior straight line muscle and interior enhancing steel ring successively; Described wedge shaped filter net is placed between outer straight line muscle and interior straight line muscle.Described wedge shaped filter net is cambridge ring filter screen, and the gap of described cambridge ring filter screen is 0.025mm.The utility model adopts inside and outside enhancing steel ring and straight line muscle, make filter cartridge construction firm, high pressure resistant, be easy to anti-cleaning, cambridge ring filter screen is when filtering, greasy dirt is entered by crack, is easy to stay on filter screen by dirt, during backwash, entered by large seam, descending gap is rinsed, and easily will extrude filter screen, and reach good backwash effect.Verify by experiment, when filter screen gap is set as 0.025mm, filter and backwash effect the best.
Description
Technical field
The utility model relates to a kind of filter core, particularly a kind of high pressure backwashing filter core be applicable in hydraulic system.
Background technique
The pollutant usually had in hydraulic working fluid Hydraulic System Reliability and component life are harmful to occurs.Working solution once element and systematic function will be caused to decline by these contaminating impurities, the lost of life.Be mingled in the particulate pollutant in working solution, impel that hydraulic parts weares and teares, the accident such as stuck, the throttle chink of hydraulic valve core and other small bore stopping up of oil channels.In addition, be suspended in the contamination particle in working solution, to some, there is the edge distributing fenestra effect and play abrasive material effect, opacity is reduced gradually, makes operation malfunctioning.Pollutant in working solution also can impel hydraulic element to corrode and working solution self deterioration is gone bad.
The working principle of high pressure filtering station is substantially identical with general metre filter principle, but the requirement of the filter precision of high pressure filtering station and the general filter of flow-rate ratio is much higher, and has self-cleaning function.
In recent years, along with the continuous increase of high-end number of holders, the backwash filter number being applied in one of critical elements in high-end hydraulic support system also gets more and more.At present, in the application process of external inlet filter support at home, there is a lot of problem.Such as: filter core in use occurs that serious distortion is out of shape; Filter core through-current capacity diminishes, and liquid resistive is large, easily blocks, and causing that support is slow in one's movements even cannot action, has had a strong impact on the manufacturing efficiency of fully mechanized mining face.Be exactly that later maintenance cost is higher in addition, the price of filter core is high and lead time is long, and serious have impact on on-the-spot use.
In the case, internal filter manufacturing firm of state develops and produces manual backwashing filter device and automatic backwashing filter, and down-hole achieves good effect in using.But, because mode of operation is manually-operable, so that the labor intensity of miner is still very large, manufacturing efficiency is not also significantly improved, in addition, filter cartridge construction does not have substantial change, remains the structure of employing stainless steel insert+collapsible silk screen, in use still occur the problems such as torsional deformation.
Summary of the invention
For not enough in prior art, the utility model provides a kind of high pressure backwashing filter core.
The technical solution adopted in the utility model is: a kind of high pressure backwashing filter core, comprise stiffener assembly and filter screen device, it is characterized in that: described filter screen device is wedge shaped filter net, described stiffener assembly ecto-entad comprises outer annular-stiffer muscle, outer straight line muscle, interior straight line muscle and interior enhancing steel ring successively; Described wedge shaped filter net is placed between outer straight line muscle and interior straight line muscle.
Described high pressure backwashing filter core, is characterized in that: described wedge shaped filter net is cambridge ring filter screen, and the gap of described cambridge ring filter screen is 0.025mm.
The utility model adopts inside and outside enhancing steel ring and straight line muscle, make filter cartridge construction firm, high pressure resistant, be easy to anti-cleaning, cambridge ring filter screen is when filtering, greasy dirt is entered by crack, is easy to stay on filter screen by dirt, during backwash, entered by large seam, descending gap is rinsed, and easily will extrude filter screen, and reach good backwash effect.Verify by experiment, when filter screen gap is set as 0.025mm, filter and backwash effect the best.
Accompanying drawing explanation
Fig. 1 is the utility model plan view;
Fig. 2 is the main pseudosection of the utility model;
Fig. 3 is the utility model left view;
Fig. 4 is the utility model cambridge ring filter screen structure figure;
Fig. 5 is the utility model cambridge ring filter screen partial schematic diagram;
In figure: 1-outer annular-stiffer muscle, the outer straight line muscle of 2-, 3-cambridge ring filter screen, straight line muscle in 4-, enhancing steel ring in 5-.
Embodiment
As shown in Figure 1-2, the utility model high pressure backwashing filter core is combined from inner to outer successively by outer annular-stiffer muscle 1, outer straight line muscle 2, cambridge ring filter screen 3, interior straight line muscle 4, interior enhancing steel ring 5, wherein, the outside of cambridge ring filter screen 3 is crack, inner side is large seam, during filtration, highly pressurised liquid is entered by outside, and inner side goes out; During backwash, washing solution is entered by inner side, and outside goes out.Adopt the little filter screen of many groups, reduce owing to often organizing filter structure, withstand voltage high when filtration and backwash, and also when backwash, emulsified liquid loss is little, and backwash effect has larger raising.Because filtration fraction is wedge shape net, gap is 0.025mm.Dirtyly to be entered by small gap when filtering, ascending gap, is easy to be retained on filter screen by dirty; And when backwash, when being rinsed by high-pressure emulsion, by descending gap, easily by the dirty filter screen that squeezes out, reach good backwash effect.
Claims (2)
