The utility model has the advantages that: used interior pressure to efflux automatic rotation and struck off the dirty stifled mode of filter screen, and washing time is short.Use the slowspeed machine transmission, can prolong filter screen backwash cycle and service life etc.Has certain space adjustability.Its scope of application has: full-automatic filter is widely used in the forefront in fields such as drinking water treatment, building circulating water treatment, industrial cycle water treatment (being useful for bathing pool most, swimming pool etc.), sewage disposal, mining industry water treatment, golf course water treatment, building, iron and steel, oil, chemical industry, electronics, generating, weaving, papermaking, food, sugaring, pharmacy, plastics, automobile industry and filters guarantee.
Description of drawings
Fig. 1 is the utility model structural representation assembly figure.
The specific embodiment
With reference to Fig. 1, a kind of automatic backwashing filter of the utility model is specifically described as follows:
As shown in Figure 1, always represent respectively: casing 1, screen pack 2, sewage inlet 3, filtered water delivery port 4 (this mouth is the high-pressure pump water inlet during backwash), rotating shaft 5, rotating shaft 6, motor 7, mechanical driver 8, backwash water inlet 9 (water inlet of self-cleaning cabinet wall), sewage outlet 10, scraper plate 11, floating thing outlet 12, control system 13, Pressure gauge and pressure switch 1, Pressure gauge and pressure switch 2 15, ring flange 16, flow device 17 with reference to label 1-17.
With reference to Fig. 1, the described automatic backwashing filter of present embodiment is its main body with a casing 1 mainly, and casing 1 is made up of two parts up and down, and is tightly connected through ring flange 16 and is one.The dismountable structure of this kind is mainly used in dismounting usefulness when the automatic backwashing filter internal components damages.When with casing 1 as one when whole, casing 1 middle part is cylindrical shape, its upper and lower side inwardly shrinks and is cone shape, 16 on this ring flange is arranged at barrel portion.The cone of casing 1 lower end partly offers sewage inlet 3, is used for sewage is introduced automatic backwashing filter.And in casing 1, going back coaxial package has a screen pack 2 that is used to filter sewage, and screen pack 2 roughly is cylindrical shape, and it is enclosed construction basically.Different with common filter screen, screen pack 2 upper ends articulate through rotating shaft 5 and said casing 1, and the lower end articulates through rotating shaft 6 and said casing 1, and two rotating shafts 5,6 are fixed on the axis of screen pack 2.Screen pack 2 can be implemented in the casing 15,6 autobiographies around the shaft thus.The rotating shaft 5 of being located at screen pack 2 upper ends simultaneously is hollow structure, and the one of which end is communicated with said screen pack 2, and the other end then passes through casing 1 and constitutes filtered water delivery port 4.Sewage gets in the casings 1 from sewage inlet 3 thus, filters out impurities with the external pressure mode screen pack 2 of flowing through, and the filtered water delivery port 4 from the upper end flows out afterwards, accomplishes whole filtration operation.
For playing the effect of automatic flushing; Offer a backwash water inlet 9 (being the water inlet of self-cleaning cabinet wall) and floating thing outlet 12 on the casing 1 upper end cone part, this backwash water inlet 9 (being the water inlet of self-cleaning cabinet wall) is connected with a high pressure backwashing pump.Casing 1 lower end cone partly offers a sewage outlet 10 simultaneously, and this sewage opens and closes through back blowoff valve (not shown) control from sewage outlet 10, is used for effluent sewerage.Casing 1 lower end is provided with a motor 7, and said motor 7 output shafts drive in rotating shaft 6 through driving device driver 8 and connect, and make said screen pack 2 around said rotating shaft rotation.Be set with scraper plate 11 on the said casing 1 barrel portion inwall, said scraper plate 11 is parallel to said screen pack 2 axis settings, and its outer face fits in said screen pack 2.Scraper plate 11 length are identical with said screen pack 2 barrel portion height.Simultaneously; Also adopted control system 13; Casing 1 top is provided with a Pressure gauge 1; Said filtered water delivery port 4 places are provided with a Pressure gauge and pressure switch 2 15 and flow device 17, and said control system's 13 connections also receive the signal that said Pressure gauge and pressure switch 1, Pressure gauge and pressure switch 2 15 and flow device 17 are sent to, and connect control motor 7 and high pressure backwashing pump.
When using, the former water of pressure gets into filters by sewage inlet 3, at first filters out impurities with the external pressure mode screen pack 2 of flowing through.Along with the accumulation of all contaminations in the filter medium in screen pack 2 outsides; Filtration channel is blocked; This moment, the force value of Pressure gauge and pressure switch 1 and Pressure gauge and pressure switch 2 15 monitorings increased (intake-outlet pressure reduction increases gradually) gradually; Differential pressure reaches when presetting definite value when flow device 17 is lower than normal discharge, and the detection signal that control system 13 will be connected in intake-outlet will convert voltage signal to, passes to motor 7 and high pressure backwashing pump.Motor 7 starts, and screen pack 2 rotates, and floating thing outlet simultaneously 12 is opened, and the impurity that scraper plate 11 will be deposited on the screen pack 2 strikes off.Then, the high pressure backwashing pump starts, and flushing water is imported from backwash water inlet 4,9, washes automatically, and floating superincumbent impurity is discharged from floating thing outlet 12.Discharge from sewage outlet 10 afterwards.The whole dirt, discharging pollution process of removing need not personnel operation, need not to shut down.Simultaneously, this control system 13 also is provided with regularly to be cleaned dirt eliminating function and manually cleans dirt eliminating function, can preset through the time; When reached preset definite value running time, when perhaps manually booting blowdown, system was with automatic starter motor 7 and backwash high pressure pump; Simultaneously, the outside in filter screen, action before and after high pressure back purge system and the blowdown apparatus; And be corresponding relation, under the prerequisite of not interrupting normal operation, only by sub-fraction product water; Filter screen is carried out the high pressure backwash, and backwash water sees through filter screen, is discharged by sewage draining exit 10 at last.Guarantee the security reliability of water outlet under any circumstance.
More than the specific embodiment of the utility model is described in detail, but it is as example, the utility model is not restricted to the specific embodiment of above description.To those skilled in the art, any equivalent modifications that this practicality is carried out with substitute also all among the category of the utility model.Therefore, impartial conversion and the modification under spirit that does not break away from the utility model and scope, done all should be encompassed in the scope of the utility model.
The cone of cabinet design upper and lower, what more can help water concentratedly leads into derivation, and sewage is more thoroughly discharged.
