Description
Technical field
The invention belongs to filter technology field, relate to the filter that a kind of backwash is used, be specifically related to a kind of filter of lf.
Background technology
Under coal mine, high-pressure emulsion recycles after need filtering at present, the general screen pack that adopts filters, because environment under ore deposit is severe, screen pack used after a period of time, will on filter screen, pile up very many impurity, these impurity can affect the rate of filtration and the filter efficiency of filter core, therefore, need in time filter core to be cleared up. Filter core need be pulled down to rear cleaning at present, this will shut down replacing filter screen, and impact is normally produced, and cost is higher simultaneously, and the replacing time is longer.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, and technical problem to be solved is: a kind of filter that is applicable to use under ore deposit is provided, and strainer filtering performance is good, and filter gauze cleaning is convenient.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: mining backwash filter, comprise urceolus, one end of described urceolus is by the first end cap seal, the other end, by the second end cap seal, is provided with net cylinder in urceolus, between one end of net cylinder and the first end cap, be connected by the first net cylinder end cap, between the other end and the second end cap, be connected by the second net cylinder end cap, in net cylinder, be provided with filter.
Wherein, in described filter, be provided with carriage, described carriage comprises two annulus, between two annulus, be connected to form the framework of tubular by many cross bars, on the outer surface of described carriage, be wound with steel wire and form screen pack, between adjacent steel wire, form the gap that can pass through for liquid, the inside of described carriage is provided with inside lining sleeve, on the barrel of described inside lining sleeve, have multiple through holes that can pass through for liquid, the inwall of inside lining sleeve surrounds inner chamber, between the outer wall of net cylinder and the inwall of urceolus, forms exocoel.
Wherein, the outside of described the first end cap is connected with the first fitting sleeve, in the first fitting sleeve, be provided with the first passage being connected with exocoel, described first end covers the first joint being connected with intracavity inter-connection, the first joint and the concentric outside that arranges and extend to the first fitting sleeve of the first end cap, the outside of the second end cap is connected with the second fitting sleeve, in the second fitting sleeve, be provided with the second channel being connected with exocoel, the middle part of the second end cap is connected with the second joint with intracavity inter-connection, the second joint and the concentric outside that arranges and extend to the second fitting sleeve of the second end cap.
In the time of the emulsion of filtration system, by the control of hydraulic valve and control system, first passage leads to emulsion, second channel and the first joint are closed, emulsion enters into after the exocoel of filter, by strainer filtering, the clean filtrate after filtration enters into inner chamber and discharges the filtration of completion system emulsion by the second joint; In the time that stopping up appears in filter core, the first joint passes into counter-flushing liquid, first passage and the second joint are closed, counter-flushing liquid enters inner chamber, then after screen pack, enter exocoel, back flush is attached to impurity and the tamper on screen pack outer wall, and the liquid after flushing is discharged by second channel, reaches the effect of cleaning and filtering net. Screen pack of the present invention adopts steel wire winding to form, and forms linear gap between adjacent steel wire, selects the screen pack of different gap according to different filtering accuracies, can adapt to filtration environment complicated under ore deposit. The backwash process used time is short, is generally 1 to 2 minute, has greatly shortened the scavenging period of filter core, can not affect operating efficiency. With respect to traditional filter core dismounting and cleaning, clean fast, cleaning performance is good, and the equipment under ore deposit that is particularly suitable for uses.
Further, be provided with multiple grooves on described cross bar, described steel wire winding forms screen pack in groove, and steel wire is installed in groove, can arbitrarily not slide, and has ensured filtering accuracy.
Further, the cross section of described groove is del, and the cross section of described steel wire is the triangle matching with groove, the seamed edge of steel wire is installed in groove, forms up-small and down-big gap between adjacent steel wire, in the time filtering, filtrate is flowed to large mouthful from the osculum in gap, good filtration effect, is not easy to stop up screen pack, in the time of backwash, backwash is also flowed to osculum from large mouthful of gap, the pressure of backwash increases, and backwash effect is good, and the used time is short.
Further, between described adjacent steel wire, fix by spot welding, adjacent steel wire position is fixed, and the gap between adjacent wires is fixed, and filtering accuracy is secure.
Further, the gap between described adjacent steel wire is 0.15mm, and this filtering accuracy is applicable to the filtration of emulsion under ore deposit, can pressure-bearing 25MPa, be equivalent to 170 object filter screens, and filtering accuracy can large 88 μ m.
Further, between described the first end cap and urceolus, be provided with sealing ring, between the second end cap and urceolus, be provided with sealing ring, good sealing effect.
Further, between described the first end cap and the first net cylinder end cap, be provided with sealing ring, between the second end cap and the second net cylinder end cap, be provided with sealing ring, good sealing effect.
