The present invention compared with prior art has following beneficial effect: when 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 by the second joint, discharges the filtration of completion system emulsion; When stopping up appears in filter core, the first joint passes into counter-flushing liquid, first passage and the second interface 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.This 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 is used.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
Fig. 1 is the structural representation of backwash filter of the present invention.
In figure: 1 is urceolus, 2 is the first end cap, and 3 is the second end cap, 4 is net cylinder, and 5 is the first net cylinder end cap, and 6 is the second net cylinder end cap, 7 is exocoel, and 8 is inner chamber, and 9 is the first fitting sleeve, 10 is first passage, 11 is the first joint, and 12 is the second fitting sleeve, and 13 is second channel, 14 is the second joint, and 15 is screw.
The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation, and the schematic diagram of accompanying drawing for simplifying, basic structure of the present invention is only described in a schematic way, so it only shows the formation relevant with the present invention.
As shown in Figure 1, backwash filter, comprise urceolus 1, one end of described urceolus 1 is by the first end cap 2 sealings, the other end is by the second end cap 3 sealings, in urceolus 1, be provided with net cylinder 4, between one end of net cylinder 4 and the first end cap 2, by a first net end cap 5, be connected, between the other end and the second end cap 3, by a second net cylinder end cap 6, be connected, in net cylinder 4, be provided with screen pack cylindraceous, between the inwall of the outer wall of screen pack and urceolus 1, form exocoel 7, the inwall of screen pack surrounds inner chamber 8, filtrate is flowed to inner chamber 8 from exocoel 7, by being arranged on the strainer filtering on inner chamber 8, the outside of the first end cap 2 is connected with the first fitting sleeve 9, in described the first fitting sleeve 9, be provided with the first passage 10 being connected with exocoel 7, first passage 10 is connected with the feed tube of system, on described the first end cap 2, be connected with the first joint 11 being connected with inner chamber 8, the first joint 11 and the first concentric outside that arranges and extend to the first fitting sleeve 9 of end cap 2, the first joint 11 is connected with the feed tube of backwash liquid, the outside of the second end cap 3 is connected with the second fitting sleeve 12, in the second fitting sleeve 12, be provided with the second channel 13 being connected with exocoel 7, second channel 13 is connected with the drain pipe of backwash liquid, the middle part of the second end cap 3 is connected with the second joint 14 being connected with inner chamber 8, the second joint 14 and the second concentric outside that arranges and extend to the second fitting sleeve 12 of end cap 3, the second joint 14 is connected with the drain pipe of system.
