Abstract
The utility model relates to a self-cleaning filter which comprises a sewage draining outlet arranged in the bottom of the self-cleaning filter and an air exhaust port in the top of the self-cleaning filter. A water inlet and a water outlet are arranged between the sewage draining outlet and the air exhaust port. A filtering area, a separation area and a sewage draining area are sequentially arranged between the water inlet and the water outlet. The filtering area comprises a filter barrel communicated with the water inlet and the water outlet, wherein a plurality of filtering columns are arranged in the filter barrel, the upper ends of the filtering columns are provided with pore plates which seal and fix the filtering columns, and the lower ends of the filtering columns are provided with the sewage draining outlet communicated with the filtering columns. The self-cleaning filter is not prone to being damaged in a utilization process and is good in filtering effect.
Description
Technical field
The utility model relates to a kind of self-cleaning filter, belongs to the purifier in the field of Environment Protection, relates in particular to the system cools water filtrations such as blast furnace, milling train, conticaster, dephosphorize by high pressure water system contaminant filter.
Background technology
Sewage enters through thick, fie screen from water inlet and filters during common self-cleaning filter work, then flows to outlet.In filter process, the fie screen surface is the impurity in the accumulated water gradually.Form the impurity screening layer, because impurity is deposited in the inboard of fie screen, therefore just formed a pressure differential in the inside and outside both sides of fie screen.When pressure reduction reached the systemic presupposition value, automatic cleaning function was activated, and the water supply of system is not around here interrupted, and backwash valve or blowoff valve are opened, and sewage is discharged by blowoff valve.The large easy distortion of this screen pack diameter, filter screen easily stops up, and the pressure reduction of filter self is mainly leaned in blowdown, the main dependence brush of cleaning and filtering impurity, brush easily wears out after operation a period of time and comes off.For a long time, traditional self-cleaning filter technique is numerous and diverse, easy obstruction, the easy compressive deformation of filter, impurity easily is gathered on the cartridge filter and forms filter pressure and increase and cause equipment damage, the aging rear cleaning device that comes off of cleaning brush lost efficacy, clearing apparatus and cylindrical shell percussion moment of torsion that the cartridge filter compressive deformation causes drive mechanism to drive increase, and stirring structure easily damages, and the design energy consumption is high, treatment effect is unstable.
The utility model content
The utility model is for defects, purpose with a kind of self-cleaning filter that a kind of in use not fragile, good filtration effect is provided.
The technical solution adopted in the utility model is for this reason: comprise the sewage draining exit that is arranged on self-cleaning filter bottom and the exhaust outlet at top, establish intake-outlet between sewage draining exit and the exhaust outlet, between water inlet and delivery port, establish successively filtering area, Disengagement zone and blowdown district, it is characterized in that, described filtering area comprises the cartridge filter that is communicated with water inlet, delivery port, be provided with some Filter columns in the cartridge filter, the Filter column upper end is provided with and is fixed and the blind bore plate, and the Filter column lower end is provided with the sewage draining exit that is communicated with each Filter column.
Described Filter column adopts the coiling of wedge type stainless steel wire, and it is trapezoidal that stainless steel wire is, outer little interior large setting.
Be provided with rotating spoon in the described cartridge filter.
Described Filter column cylindrical distribution.
Described Filter column at right angle setting arranges.
Be provided with differential pressure switch at water inlet, water outlet.
The utility model has the advantages that: 1) the utility model adopts a plurality of undersized Filter columns to substitute traditional large filter structure form, and in use, Filter column is difficult for compressive deformation than the version of screen pack, and greatly improve service life; 2) in order to make filtered water inlet even, be provided with inner core in filter interior, upper orifice plate, former water has guaranteed to filter the uniformity of water distribution by each Filter column uniform water distribution after the water inlet; 3) in order to guarantee the effect of blowdown, all Filter columns are circle distribution, and whirligig only need rotate once can guarantee the Filter column blowdown once, has reduced blowing time, the backwash water yield of saving; 4) in order to improve backwash effect, in filtering area, establish rotating spoon, scratch stream with generation, improve backwash effect; 5) for the clean-up effect in the energy real-time monitored self-cleaning filter, in order to can in time take measures according to actual conditions, offer Pressure gauge and differential manometer mouth at filter body, in time react according to situation about detecting; 6) Filter column of the present utility model upper end is with the orifice plate sealing, and in the filter body bottom one dredge pump is set, and the suction by dredge pump reaches the blowdown purpose with the dirt sucking-off; 7) the utility model Filter column adopts the coiling of wedge type stainless steel wire, and it is trapezoidal that stainless steel wire is, outer little interior large setting, when anti-the cleaning, because opening is more and more less, the pressure of current is increasing, so very easily will stick to the dirt that filters on the post jamb and wash away, and realize instead cleaning.

Fig. 2 is the sectional view of the utility model Filter column.
1 is that water inlet, 2 is that cartridge filter, 3 is that orifice plate, 4 is that Filter column, 5 is that rotating spoon, 6 is that delivery port, 7 is that differential pressure switch, 8 is sewage draining exit among the figure.
The specific embodiment
The utility model comprises the sewage draining exit 8 that is arranged on self-cleaning filter bottom and the exhaust outlet at top, establish intake-outlet between sewage draining exit 8 and the exhaust outlet, between water inlet 1 and delivery port 6, establish successively filtering area, Disengagement zone and blowdown district, described filtering area comprises the cartridge filter 2 that is communicated with water inlet 1, delivery port 6, be provided with some Filter columns 4 in the cartridge filter 2, Filter column 4 upper ends are provided with and are fixed and blind bore plate 3, and Filter column 4 lower ends are provided with the sewage draining exit 8 that is communicated with each Filter column 4.
Described Filter column 4 adopts the coiling of wedge type stainless steel wire, and it is trapezoidal that stainless steel wire is, and outer little interior large setting is provided with rotating spoon 5 in the cartridge filter 2.
Described Filter column cylindrical distribution, described Filter column at right angle setting arranges.
Be provided with differential pressure switch at water inlet 1, delivery port 6 places.
Workflow of the present utility model is: 1) the former water of required purification is at first entered in the filter by water inlet pipe, in filter along inner core distributed flow up and down, enter again Filter column 4, at water inlet 1 place's electric gate valve or hand-operated valve, be used for regulating flow and the maintenance of water; 2) former water is uniform enters Filter column 4, and impurity is intercepted at the outside of Filter column 4, and the impurity that is blocked is external by the blow-off pipe expelling tube; 3) water of cartridge filter 2 is crossed delivery port 6 connections, and the water after the purification is provided with water outlet hand-operated valve or motor-driven valve by outside delivery port 6 discharge filters at delivery port 6; 4) absorption impurity that the filter post arranged can increase gradually with the increase of filtration time, cause the pressure at the Inlet and outlet water two ends of filter to increase, be provided with differential pressure switch 7 filtering out water end (W.E.), when differential pressure reaches setting value, automatically open the blowdown whirligig Filter column 4 is carried out backwash, the general backwash time is 1-2 minute, re-starts after the backwash to filter flow process.
