The specific embodiment
Below, with reference to drawings and Examples the filter that the utlity model has automatic cleaning function is elaborated:
Shown in Fig. 1～3, the filter with automatic cleaning function of the present utility model comprises housing 1, connect loam cake 2 in housing 1 upper end, connect lower cover 3 in housing 1 lower end, reductor 4 is set on the top of loam cake 2, in the inside of housing 1 blow-off pipe 5 is set, reductor 4 is connected with blow-off pipe 5.Housing 1 comprises epicoele 6 and cavity of resorption 7, is separated by toroidal membrane 8 between epicoele 6 and the cavity of resorption 7.The cylindrical of toroidal membrane 8 is connected with the inwall of housing 1, and the interior circle of toroidal membrane 8 closely contacts with the cylindrical that single chimney filter is crossed filter core 10.In the middle part of housing 1 differential pressure controller 9 is set.
In the inside of housing 1 single chimney filter is set and crosses filter core 10, one side is provided with sewage inlet pipe 11 in housing 1 bottom, on sewage inlet 11 pipes sewage pressure sensor 12 is set.At housing 1 top opposite side pure water inlet pipe 13 is set, water purification pressure sensor 14 is set on pure water inlet pipe 13.
Epicoele 6 is communicated with the outer wall that single chimney filter is crossed filter core 10, and cavity of resorption 7 is communicated with the inwall that single chimney filter is crossed filter core 10.At lower cover outlet of sewer bend pipe 16 and supporting leg 17 are set for 3 times respectively, electric butterfly valve 15 is set on outlet of sewer bend pipe 16.
Blow-off pipe 5 comprises that mandrel 18, pipe 19 and suction draw flat tube 20.The axle of mandrel 18 and reductor 4 is connected, the lower end of mandrel 18 is connected with the upper end of pipe 19, be provided with respectively on the pipe 19 a plurality of have between up and down certain intervals and be that flat tube 20 is drawn in axle, mutual symmetrical suction with pipe 19, it is four that flat tube 20 is drawn in suction of the present utility model, and suction is drawn flat tube 20 and is communicated with pipe 19.In the bottom of pipe 19 retainer ring 21 is set.
Draw on the flat tube 20 in suction and to form a plurality of suction Zi, one of the lunar mansions 22, the utility model is four, and a side of drawing flat tube 20 in suction is provided with adjusts seat 23, brush 24 is set adjusting on the seat 23, draws flat tube 20 and adjust between the seat 23 in suction backing plate 25 and bolt 26 are set.
Operation principle of the present utility model and process:
Normal operating conditions: for convenience of carrying out smoothly of blowdown, adopted in design the sewage medium of handling single relatively chimney filter cross the flow direction of filter core 10 " in advance to go out ", be the inside inflow of sewage from filter core, by the filtration of filter core, water purification flows out from the outside of filter core.Enclosure interior is divided into two chambeies up and down with dividing plate, and epicoele is communicated with the outer wall that single chimney filter is crossed filter core, and cavity of resorption is communicated with the inwall that single chimney filter is crossed filter core; Impure sewage flows into the cavity of resorption of housing through the sewage inlet of cavity of resorption, and the inlet of crossing filter core through single chimney filter passes filter core and filters, and the water purification after the filtration flows into epicoele, flows out through pure water inlet.
Blowdown duty: at sewage inlet sewage pressure sensor (pressure of establishing sewage inlet is P1) is set, water purification pressure sensor (pressure of establishing water purification place mouth is P2) is set at pure water inlet.When being blocked in, the impurity in the sewage will cause sewage inlet and pure water inlet pressure reduction to rise when single chimney filter filters on the in-core wall, when pressure differential deltap P=P1-P2 reaches setting value, pressure sensor sends the signal of telecommunication to differential pressure controller and starts the blowdown process, the differential pressure controller output signal is opened electric butterfly valve and is started reductor, blow-off pipe rotation under reductor drives; Because blow-off pipe is communicated with atmosphere, P2 (water-purifying cavity pressure)＞P0 (atmospheric pressure), near the suction nozzle on the blow-off pipe, produced a low-pressure area, because low pressure systemic action, water purification after the filtration is under the effect of P2 pressure, pass single chimney filter and cross filter core and carry dregs in the filter core slit that is swept away by it secretly, enter outside blow-off pipe flows out jar.
Water before filtering is inhaled in the blow-off pipe by the radial clearance between the inwall of the suction nozzle on the blow-off pipe and filter core under pressure P 1 effect, will be arrested in solid particle filter cake on the filter core inwall by the interior suction souring of current and wash away and brought into blow-off pipe by current and flow out outside the jar.Carry out pressure reduction and can descend along with what clean, when pressure reduction is reduced to setting value when following, electric butterfly valve cuts out, and reductor stops the rotation simultaneously, the end of blowdown process.
