Abstract
The invention discloses a settling type anti-blocking filter which comprises a liquid inlet, a liquid inlet valve, a liquid inlet pipe, a settling tank, a slag discharging valve, a slag discharging opening, a filtering film, a liquid discharging pipe, a liquid discharging valve, and a liquid discharging opening, wherein the liquid inlet, the liquid inlet valve, the liquid inlet pipe, the settling tank, the slag discharging valve, and the slag discharging opening jointly form a settling system in sequence from top to bottom; the liquid inlet, the liquid inlet valve, the liquid inlet pipe, the settling tank, the filtering film, the liquid discharging pipe, the liquid discharging valve, and the liquid discharging opening jointly forms a filtering system in sequence. The settling system and the filtering system are integrated. According to the settling type anti-blocking filter, gravity settling factors are combined with filtering of the filtering film, so that the filtering film can be prevented from being blocked, and the filtering efficiency is improved; the settling type anti-blocking filter is suitable for the filtering of various suspensions.
Description
Technical field
The present invention relates to a kind of filter, especially a kind of decanter type anti-blocking filter.
Technical background
Sedimentation and to filter be the conventional means of decentralized photo and decentralized medium in suspended liquid, extensive use in scientific experimentation, industrial and agricultural production, people's daily life.Sedimentation is because the density of decentralized photo and decentralized medium is different, dispersed phase particles is in the directed movement of the lower generation of the field of force (gravitational field or centrifugal force field) effect, wherein utilizes the gravity of dispersion particle in suspension itself and obtains the gravitational settling that is called of separation.Filtration is process fluid purification being purified by special device.Filter operation is that the liquid (or gas) in motive force or other External Force Acting low suspension liquid gas of solid particulate matter (or containing) sees through medium, solid particle and other materials are filtered medium and hold back, thus the operation that solid and other materials are separated with liquid (or gas).
The actual filter plant kind using is a lot of at present, but often there is common weak point in design: the one, do not consider and make full use of the element paritng dispersed phase particles of dispersed phase particles gravitational settling, the simple membrane retention dispersed phase particles that relies on, cause dispersed phase particles to be constantly deposited on filter membrane and stop up filter membrane hole, the filter membrane of having to frequently change; The 2nd, do one's utmost to increase the poor and filter membrane aperture that reduces to the minimum of filter membrane pressure at both sides, the contradiction that decentralized photo and decentralized medium are separated from each other all concentrates on filter membrane, increases filter membrane pressure at both sides, causes that energy consumption increases, filter efficiency declines.
Summary of the invention
The present invention makes full use of gravitational settling and two kinds of separation means of membrane filtration, the supernatant liquor obtaining after dispersed phase particles sedimentation is filtered, reduce the pressure differential of filter membrane both sides, preventing that dispersed phase particles is deposited on stops up filter membrane hole on filter membrane, reduce filter membrane pressure at both sides, reduce energy consumption, improve filter efficiency.
For realizing object of the present invention, the technical scheme adopting is:
A kind of decanter type anti-blocking filter, is made up of parts such as inlet, liquid feed valve, feed tube, settling tank, residual cake valve, slag-drip opening, filter membrane, discharging tube, tapping valve, leakage fluid drams.The parts such as inlet, liquid feed valve, feed tube, settling tank, residual cake valve, slag-drip opening form sedimenting system from top to bottom successively jointly.The parts such as inlet, liquid feed valve, feed tube, settling tank, filter membrane, discharging tube, tapping valve, leakage fluid dram form filtration system successively jointly.Sedimenting system and filtration system are integrated.Inlet lower end is at settling tank middle part, and residual cake valve and slag-drip opening are in settling tank bottom, and filter membrane is at settling tank top.
In settling tank, dispersed phase particles in suspension is deposited to settling tank bottom gradually owing to being subject to the effect of gravity, decentralized medium in suspension floats to settling tank top gradually because density is less than dispersed phase particles, constantly assemble so form settling tank bottom filter residue, settling tank top are constantly assembled supernatant liquor state near filter membrane place.The result of Here it is gravitational settling.
Due to the hydraulic pressure that inlet liquid level forms higher than leakage fluid dram liquid level, in filtration system, the supernatant liquor at settling tank top runs into filter membrane, and decentralized medium automatically sees through filter membrane and enters discharging tube, then discharges through tapping valve and leakage fluid dram; Dispersed phase particles is trapped within filter membrane below can not pass through filter membrane.Because the effect automatic sedimentation of gravity becomes filter residue to settling tank bottom, filter membrane on stopped up filter membrane hole and can not be deposited on by the dispersed phase particles of membrane retention.
Assemble when more when settling tank bottom filter residue, open residual cake valve, filter residue is discharged by slag-drip opening.
In the time of dispersed phase particles that suspension to be filtered contains different-grain diameter, can organize the different decanter type anti-blocking filter series connection in filter membrane aperture more and use.Both can guarantee carrying out smoothly of filter operation, and can classify again and obtain the filter residue of different-grain diameter.
The present invention combines gravitational settling factor and membrane filtration, and its beneficial effect is: can prevent that filter membrane from stopping up, and improves filter efficiency.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present invention.In figure: (1) is inlet, (2) be liquid feed valve, (3) be feed tube, (4) be settling tank, (5) are residual cake valves, (6) slag-drip opening, (7) be filter membrane, (8) be discharging tube, (9) are tapping valves, and (10) are leakage fluid drams.
The parts such as inlet 1, liquid feed valve 2, feed tube 3, settling tank 4, residual cake valve 5, slag-drip opening 6 form sedimenting system from top to bottom successively jointly.The parts such as inlet 1, liquid feed valve 2, feed tube 3, settling tank 4, filter membrane 7, discharging tube 8, tapping valve 9, leakage fluid dram 10 form filtration system successively jointly.Sedimenting system and filtration system are integrated.
Specific implementation method
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
Open liquid feed valve 2 and tapping valve 9, close residual cake valve 5, constantly add suspension to be filtered from inlet 1.Suspension, through liquid feed valve 2, feed tube 3, enters settling tank 4.In settling tank 4, the dispersed phase particles in suspension is deposited to gradually the bottom of settling tank 4 under Action of Gravity Field, and dispersant floats to settling tank 4 tops and forms supernatant liquor.Supernatant liquor is after filter membrane 7 filters, and dispersant (filtrate) is discharged by discharging tube 8, tapping valve 9, leakage fluid dram 10.Dispersed phase particles is held back the rear effect because of gravity by filter membrane 7 and is deposited to settling tank bottom, forms filter residue.When filter residue accumulates when more, open residual cake valve 5, filter residue is discharged through residual cake valve 5 and slag-drip opening 6.Thereby realize the object of filtering.
