Description
The present invention relates to a kind of filter, be particularly useful for doing final the processing with the waste water that comes from city and Industrial Wastewater Treatment equipment resulting from commercial processes.
So far, adopt permeable fabric or mesh to come specially to make the final filter of handling to the waste water that comes from industrial technology with from the waste water that the final stage of water treatment facilities flows out, all be designed to be arranged in the horizontal rotation cartridge system use mesh that drives on the roller bearing or permeating fabric, its shell is equipped with hexagonal, as to be hung with mesh framework.This mesh is made by synthetic fibers or wire.The sewage that flows through the revolving drum surface passes to filter tissue and flow out treating apparatus and arrives at its destination owing to the water-head of entrance and exit.Being deposited on an inner filtration, to organize the impurity of inner surface be to utilize from the nozzle injection pressure water that is positioned at the tube top to remove, and be collected in a groove that is arranged in tube, from they will be introduced to other places here.
The shortcoming of said apparatus is the layout of its horizontal level, and wherein, only some filtration organizes wet zone in action, and the remainder on tube top fails to bring into play filtration because of being used to the cleaning and filtering tissue.Another shortcoming is need big relatively combined area.Also have a shortcoming to be that revolving drum needs face seal, and the harmful effect that can be subjected to impurity in the water service life of sealing, and sealing can not be accomplished fully closely.Utilization is from the outside, and it also is very disadvantageous just spraying water cleaning and filtering to organize from outlet side, especially under the situation that dense filtration tissue or mesh need high-pressure water, because contaminated tissue can produce very big resistance.
Also have another kind of filter, its principle is identical with above-mentioned device, and different is, and its tube is to be positioned to drive on the belt, rather than is positioned at swing roller, and described driving belt is suspended from the belt pulley of level.This horizontal belt wheel is arranged on the common axis that is driven the tube top.Filtration tissue in the framework is designed to the half round post of convexity to increase filter area.
Except above-mentioned, the shortcoming of this solution also is, the filtration tissue that is cleaned is subjected to the impact of the cleaning current of different angles and distance, thereby bear at the cylindrical surface top in the strong filtration tissue that sprays of rinse water can the very big stress of generation, and, filter the area of fixation of tissue in frame area and can not fully clean.Another unfavorable factor is exactly that the replacing of filtering tissue bothers very much.
Utilize the final filter of handling of waste water that is particularly useful for of the present invention, can eliminate above-mentioned shortcoming and unfavorable factor.The main points of invention are, it is made of a casing, this casing is separated into an introducing space and the discharge space around each tubular filter element that links to each other with the inner space of at least one tubular filter element by the opening in the horizontal dividing wall by the dividing wall of a vertical dividing wall and a level, each tubular filter element is in being arranged at vertically more than the opening on the horizontal dividing wall and with its underpart periphery firmly and watertight ground is fixed in described horizontal dividing wall, simultaneously, a rotation suction apparatus is contained in the inner space of tubular filter element, the quill shaft that this device has at least a suction manifold and to be positioned at tubular filter element axis place links to each other, and is connected in a negative pressure source.
Its favourable part is that the bottom of filter element is a permeability shell, and top is a solid encasement.
Its favourable part also is, a spilling water border that reaches the boundary line height between permeability shell and the solid encasement at least arranged discharging between space and the extraneous space.
The principal advantages of filter of the present invention is the vertical location of tubular filter element, and it can be used for whole permeability shell surface almost to dispose of sewage, and this is one of high efficiency prerequisite of device.
Another advantage is that the tubular filter element is to be installed on securely on the horizontal division board, can introduce and discharge the good sealing of formation between the space like this, and compared with the filter element that needs to seal a rotation in existing solution, it is more simple.The advantage of a significant is that the design of tubular filter element and whole filter drive and the design of control all becomes simpler apparently, thereby have alleviated the weight of device and reduced the combined area of installing.
Also having an advantage to be, is to change whole tubular filter element or only change the permeability shell all will be easy to realize.
Another one is also advantageous in that it can be installed in one group of tubular filter element in the same casing, thereby can reduce and the proportional combined area of the water yield of whole device, especially can reduce its actual cost.
Accompanying drawing shows one embodiment of the present of invention, and wherein, Fig. 1 represents the front elevational schematic that filter is cut open along vertical axis, and Fig. 2 represents the schematic cross-section that filter is cut open along the line II-II among Fig. 1.
Filter of the present invention comprises a casing 1, for example is tubular, and this casing is equipped with the outlet 3 that an inlet tube 2 and that is used to introduce sewage is used to discharge treated water.Inlet tube 2 causes introduces space 4, and outlet 3 causes discharges space 5.Introducing space 4 separates with the horizontal dividing wall 7 of discharging the vertical dividing wall 6 of space 5 quilts and adjoin mutually with it.Horizontal dividing wall has an opening, and introducing space 4 is interconnected with the inner space 8 of vertically-oriented tubular filter element 9.The lower periphery of filter element 9 more than opening firmly and watertight be connected in horizontal dividing wall 7.One permeability shell 10 is arranged at the bottom of filter element 9, and it can be a screen cloth, and its size of mesh opening is corresponding with the degree of purity of required processing water.One solid encasement 11 is arranged at the top of filter element 9.Discharge the whole outer circumference surface of space 5 around filter element 9.
Contain one in the inner space 8 of tubular filter element 9 and be formed at the rotary impurity suction apparatus 12 at the axis place of tubular filter element 9 by a hollow rotary shaft 13, this device has a suction manifold 14 at least, and its inlet entirely leans against on the inner surface of tubular filter element 9.Present embodiment shows three suction manifolds 14, and each tubular filter element 9 inner surface with 1/3rd height contacts.The quill shaft 13 of suction apparatus 12 is installed on an annular seal space 15 that is positioned at casing 1 bottom 16 hermetically with pivot.One is pivoted on driving shaft 17 casing 1 outside, that have the belt pulley 18 that links to each other with drive unit 19 links to each other with the quill shaft in the annular seal space 15 13.In the zone that quill shaft 13 is connected with driving shaft 17, not shownly be used to make the water of suction and impurity to enter the opening of aspiration 20 by annular seal space 15.A lining 21 that is arranged in tubular filter element 9 upper ends is filled in and be pivoted in the upper end of quill shaft 13.The outlet 3 of treated water links to each other with spill cavity 22, and this spill cavity has a spilling water border 23 that is arranged in the filter discharge space 5.This filter also is equipped with and is used for detecting the detector (not shown) that the water level of introducing space 4 and tubular filter element 9 is discharged the drop H of space 5 middle water levels together.
The course of work of filter of the present invention is as follows:
Sewage flows into the introducing space 4 of casing 1 by inlet tube 2.Because the hydrostatic pressing gradient that water-head H caused between the introducing space 4 of tubular filter element 9 and the discharge space 5 makes sewage flow into the inner space 8 of tubular filter element 9 and passes infiltrative shell to enter discharge space 5.Owing to pass infiltrative shell 10, sewage is by removal of impurities, and overflows spilling water border 23 and entered spill cavity 22 from discharging space 5.From it leaves filter by outlet 3 here.
The impurity that is deposited on the permeability shell 10 of tubular filter element 9 makes the resistance of infiltration increase gradually, the rising that this will cause the inner space 8 of tubular filter element 9 and introduce space 4 middle water levels, just make the hydrostatic pressing gradient rise, when arriving to a certain degree, the detector (not shown) just starts rotatablely moving of the suction apparatus 12 that has suction manifold 14, and starts a negative pressure source (not shown) simultaneously.Thereby deposition impurity is mechanically removed and is siphoned away simultaneously, and draws casing 1 by quill shaft and aspiration 20.So just recovered sewage and passed the full flow of the permeability shell 10 of tubular filter element 9, and made water-head H reduce to required value in inner space 8 and the introducing space 4, this moment, suction apparatus 12 promptly stopped operating, and the suction of impurity is also ended immediately.Above-mentioned running is repeatedly carried out.
Filter of the present invention can be used to flowing water do economy with before removal mechanical admixture wherein reliably.
