Abstract
The utility model discloses an outer scrubbing type filter, which mainly comprises one, two or a plurality of filters, a scrubbing tank and a medium pump; according to the cleaning process, a pipeline is connected with a control valve and constitutes the outer scrubbing type filter. When being in use, an electrical appliance provides power and sewage can be filtered; when a filter material need to be washed, the filter material is elevated into the scrubbing tank and water can wash out the oil and the suspended solid particles trapped on the filter material; the sewage is exhausted out of the scrubbing tank; after being scrubbed and become clean, the filter material can be taken back to the filter tank and be recycled. The utility model is suitable to the oily sewage and turbid sewage treatment.
Description
Affiliated technical field
The utility model relates to environmental protection equipment, and outer scrubbing type filter is the water treatment cleaning equipment that is used for removing sewage oil or suspension.
Background technology
The protection environment is a fundamental state policy of China, and water pollution control is the major subjects of environmental protection.Filtration is used widely in the processing of sewage as a kind of very effective water purification technology.Filter is used in the sewage disposal of industries such as oil and petrochemical industry widely.It is big to exist the backwash water consumption with lighter filtrate as its filtrate backwash mode of filter (as walnut shell filter) of filter medium such as impeller stirring-type, interior scrubbing type etc., the halfway problem of backwash.
Summary of the invention
The purpose of this utility model provides a kind of outer scrubbing type filter, and it adopts the external jar filtrate to pollution of washing by rubbing with the hands to carry out backwash, thereby improves the backwash effect of filtrate; Adopt separate unit, two or the shared Scrubbing apparatus of multiple devices, improve utilization rate of equipment and installations; Be provided with a filtrate reclaim line, the filtrate after feasible the cleaning does not rest on to be washed by rubbing with the hands in jar and the pipeline.
The purpose of this utility model is achieved in that on the filtering tank back wash line medium pump is installed, and medium pump is connected and installed with through pipeline and washes jar by rubbing with the hands, according to cleaning process, is connected with control valve by pipeline and constitutes.Wash jar by rubbing with the hands by one, two or many shared one of filters, realize that the pollution of filtrate is cleaned.According to designing requirement, be provided with a filtrate reclaim line, the filtrate after feasible the cleaning does not rest on to be washed by rubbing with the hands in jar and the pipeline.After filtrate pollutes, light filter material promotes to enter by medium pump and washes jar by rubbing with the hands when needing to clean, waterpower is washed oil and the suspension solid particle that will hold back on the filtrate by rubbing with the hands and is come off, dirt is discharged from washing jar water out by rubbing with the hands, and filtrate circulates and washes regeneration by rubbing with the hands through washing a jar import-wash by rubbing with the hands jar-wash by rubbing with the hands a jar filtrate outlet-control valve-filtering tank-control valve-medium pump-wash by rubbing with the hands a jar import by rubbing with the hands.Wash Shi Laishui by rubbing with the hands and constantly replenish, finish a part of backwash sewage in back and clean the retaining power of recovery medium by forward when washing by rubbing with the hands from filtering tank bottom.

Fig. 2: wash jar (16) by rubbing with the hands mainly by housing, screen casing and a water inlet, a delivery port and one or more filtrate export mixes.
The specific embodiment
With reference to Fig. 1, Fig. 2, medium pump (18) is installed on the filtering tank back wash line, medium pump (18) is connected and installed with through pipeline and washes jar (16) by rubbing with the hands, according to cleaning process, is connected with control valve by pipeline and constitutes.
Wash jar by rubbing with the hands by one, two or many shared one of filters, realize the backwash of filtrate.During backwash, backwash water and supplementing water after filtration water inlet (21) through control valve (5) enter filtering tank (19) or backwash water and supplementing water after filtration water inlet (21) enter filtering tank (20) through control valve (15) and make filter material layer, open with control valve (7) or control valve (13) simultaneously, coupled (24) or nozzle (25) work, make the filtering layer filtrate loosening, fluidisation, light filter material promotes to enter by medium pump (18) washes jar (16) by rubbing with the hands, waterpower is washed oil and the suspension solid particle that will hold back on the filtrate by rubbing with the hands and is come off, dirt is discharged from washing jar water out by rubbing with the hands, and filtrate is through washing a jar import-wash by rubbing with the hands jar (16)-wash a jar filtrate outlet-control valve (7)-filtering tank (19) by rubbing with the hands by rubbing with the hands or washing a jar import-wash by rubbing with the hands jar (16)-wash by rubbing with the hands a jar filtrate outlet-control valve (13)-filtering tank (20) by rubbing with the hands.According to cleaning needs, circulate through control valve (2) or control valve (3)-medium pump (18)-wash by rubbing with the hands a jar import and to wash regeneration by rubbing with the hands.Washing Shi Laishui by rubbing with the hands constantly replenishes from the filtering tank bottom.Before backwash finished, control valve (7) or control valve (13) were closed, and control valve (10) is closed, and nozzle (24) or nozzle (25) quit work, and enter pipeline filtrate recovery process.Medium pump suction this moment mainly be water, by hydro powered make wash by rubbing with the hands jar in and filtrate in the continuous pipeline through washing jar (16) filtrate outlet-control valve (6)-filtering tank (19) by rubbing with the hands or washing jar (16) filtrate outlet-control valve (14)-filtering tank (20) by rubbing with the hands.A part of backwash sewage cleans by forward after backwash is finished, and recovers the retaining power of medium.
Filtrate carries out the forward filter cleaning process initial stage after backwash finishes, water outlet this moment does not reach the effluent quality requirement, filters water outlet and discharges through control valve (9) or control valve (11)-sewage draining exit (22).
When being used for on-the-spot sewage water filtration, control valve (1) or control valve (4) are controlled sewage respectively and are entered filtering tank (19) or filtering tank (20); Control valve (2) or (control (3) is for washing the preceding pipe-line control valve of pump by rubbing with the hands; Control valve (5) or (15) are backwash inlet pipeline by-pass valve control; Control valve (8) or control valve (12) are the clear water pipe-line control valve door after filtering tank (19) or filtering tank (20) filter; Control valve (9) or control valve (11) are for recovering the defective pipe-line control valve door that enters sewage draining exit of filtration initial stage water outlet after the filtrate backwash; Control valve (6) or control valve (14) clean the pipe-line control valve door that filtrate reclaims in the pipeline of back for the filtrate of washing jar (16) by rubbing with the hands; Control valve (7) or control valve (13) return the filter tank pipe-line control valve for after the filtrate backwash; Outlet water control valve (10) is for washing a jar blowoff line by-pass valve control by rubbing with the hands.
The filter overall operation is according to filtration mechanism, finishes jointly in instrument, instrument and automatic control system.Its control has pressure reduction control and timing controlled dual-use function concurrently.Along with time lengthening, when reaching certain value, filtering layer pressure reduction promptly enters the backwash state, when pressure reduction does not reach setting value but filtration time reaches when setting value equipment also enters the backwash state, also pressure difference control and time control in backwash process, when reaching certain value, backwash pressure reduction promptly stops backwash, when reaching setting-up time, also stop backwash, and enter next flow process.Its running is for filtering → wash by rubbing with the hands → backwash → clean and moving in circles.
