Abstract
The utility model discloses a radially extended oily water filter which comprises a tank body, wherein the tank body is provided with a water inlet pipe, an air inlet pipe, a filter cartridge, a backwashing water outlet and an oil discharge outlet; a filter element is arranged in the filter cartridge; a water collecting drum is arranged at the center in the filter cartridge, the water collecting drum is connected with a water outlet pipe; the bottom of the tank body is provided with a blow-down pipe; the bodies of the filter cartridge are densely provided with meshes through which water passes, the filter cartridge is composed of a left cartridge body and a right cartridge body which are nested and combined; and the filter cartridge is pushed and pulled to stretch out and contract back through a power device; and the cartridge bodies are provided with meshes through which water passes. The overall volume of the filter cartridge is changed through radially changing the width of the filter cartridge; when the filter cartridge contracts back, the filter element is compressed, so that sewage in the filter can be filtered, and when the filter cartridge is pushed to stretch out, the filter element gets loose, so that the filter element can be backwashed. The volume is changed when the left and right filter cartridges move left and right horizontally along the radial direction, and when sewage comes into the filter cartridge from the bottom of the tank body, the sewage can pass through most of the filter element from bottom to top; and due to the change of flow direction of filtering, a better filtering effect can be achieved.
Description
Technical field
The utility model relates to sewage treatment area, refers in particular to a kind of by oil-polluted water being carried out to the filter of purification filtering processing.
Background technology
Industrialization oil-polluted water complicated component, contain oil slick, silt or oil-containing fixture etc., mainly adopt at present two media or more medium filter, or fiber ball filter is processed, while adopting these equipment to process, pollutant in water all adsorbs screening throttling by filter core, after filtrate is saturated, carries out backwash, and during backwash, pollutant fills on filter core and separates under stirring action again.After long-time filtration treatment, filter core is prone to and hardens, and oil slick is also difficult for discharging in time, and poor filtration effect, finally causes processing water not up to standard, needs to change in time filtrate, has improved use cost.Meanwhile, existing filter is all to be intake by top, and the filter core of flowing through from top to bottom carries out filtration treatment, single flow direction, and some sewage of not flowing through in filter core upper strata, utilization rate is lower, has also affected filter effect.In addition, the state adjustment of the filtration of cartridge filter and backwash, generally adjusts by upper and lower compression, cannot change the width of cartridge filter.
Utility model content
Based on the deficiencies in the prior art, main purpose of the present utility model be to provide a kind of filter efficiency and quality high, operating cost is low, a kind of radial expansion oil-containing sewage filter that can adjust the width of cartridge filter.
The utility model provides a kind of radial expansion oil-containing sewage filter, comprise tank body, described tank body is provided with water inlet pipe, air inlet pipe, cartridge filter, recoil delivery port, oil drain out, in described cartridge filter, be provided with filter core, in described cartridge filter, center is provided with Water collecting tube, described Water collecting tube connects outlet pipe, described tank base is provided with blow-off pipe, described cartridge filter stack shell is furnished with mesh to pass through water, described cartridge filter combines by left and right two-section barrel jacket is folded, flexible by a power set left and right push-and-pull, described cylindrical shell is laid with mesh so that current are logical.
Preferably, described left and right two-section cylindrical shell comprises left-hand cylinder body and right cylindrical shell, and described power set promote it at horizontal extension in the radial direction by pull bar, and when power set pushing drawing rod stretches, cartridge filter launches, and when pull bar shrinks, cartridge filter compresses and tightens up.Realize cartridge filter in contraction and the stretching of radial direction, to change the state of cartridge filter.Described power set are located in cartridge filter, and it is cylinder.
Preferably, described left-hand cylinder body and right cylindrical shell are semicircle tubular, and both diameters are identical.The top, junction of described left-hand cylinder body and right cylindrical shell is provided with that package board, side are provided with side package board, bottom is provided with lower package board, makes cartridge filter keep closed state, prevents that filter core from therefrom dropping out.
Preferably, described water inlet is arranged at the bottom of tank body, makes sewage be entered in cartridge filter and be filtered by bottom.Described oil drain out and recoil delivery port are located at respectively the both sides, top of tank body, for deriving respectively greasy dirt and backwashing water.
Preferably, described air inlet pipe is laid in cartridge filter below, for advertising filter core to cartridge filter ventilation.
Compared with prior art, a kind of radial expansion oil-containing sewage filter of the utility model has adopted the width that radially changes cartridge filter to change the overall volume of cartridge filter, when cartridge filter shrinks, filter core compresses, can carry out filtration treatment to the sewage entering, when cartridge filter is promoted and while stretching, filter core is loose, can carry out backwash to filter core.Left and right cylindrical shell radially level moves left and right to change volume size, and meanwhile, sewage is entered in cartridge filter by tank base, can be from bottom to top, then pass through most filter core from top to bottom, the flow direction of filtration changes, improve the utilization rate of filter core, brought better filter effect.Left-hand cylinder body and right cylindrical shell are respectively semicircle shape, and tension member promotes and while stretching, the width of the cartridge filter that it combines increases, and by compression and stretching, extension radially, changes the overall volume of cartridge filter, makes under backwash state again, and loose being easy to of filter core cleaned.
