The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1, a kind of membrane filtration pump, comprise clear liquid mouth 2, exhaust outlet 3, filter pump housing 4, inlet 5, refluxing opening 6, slag-drip opening 10 and recoil tank 11, described recoil tank 11 is connected to the side of filter pump housing 4, described clear liquid mouth 5 is arranged on the outer ring, top of filter pump housing 4, described exhaust outlet 3 is arranged in the middle of the top of filter pump housing 4, described inlet 5 be arranged on recoil tank 11 1 sides and with filter pump housing 4 in circuit communication, described refluxing opening 6 is arranged on inlet 5 tops, and described slag-drip opening 10 is arranged on filter pump housing 4 bottom one sides.Filter pump housing 4 upper side are provided with liquid level gauge 1.Filter pump housing 4 bottom one sides are also connected with acid solution mouth 8 and leakage fluid dram 9, and described acid solution mouth 8 and leakage fluid dram 9 pass through pipeline communication with slag-drip opening 10.On filter pump housing 4, be connected with air inlet 7, described air inlet 7 is communicated with acid solution mouth 8, leakage fluid dram 9, slag-drip opening 10 by pipeline.Recoil is filled with 11 sides and is provided with recoil mouth 12, and recoil tank 11 bottom one sides are provided with sewage draining exit 13.
Workflow explanation of the present utility model:
In liquid feeding pump is incited somebody to action, squeeze into automatic back-washing surface filtration pump with waste water, the clear liquid after filtration flows into clean solution tank through upper barrel body clear liquid mouth, returns to ashing-milk of lime modulating system and again enters the circulatory system as slurrying liquid.And solid particle is blocked on filter membrane surface, while reaching certain thickness, filter pump enters backwash state, filter cake hightails filter membrane surface settlement to filter pump cylinder body bottom, when bottom filter residue runs up to when a certain amount of, the valve open of bottom, enters mud pit by filter residue.
Whole filtration, recoil, tapping process all adopt controller automatically to control.
Slag inclusion mud is timed and is delivered to plate compression, blob of slag outward transport.Press filtration fluid is returned and is reclaimed pond.
Filter: filtered fluid is squeezed into filter pump lower barrel body, and turbid liquid filters through filter membrane, and clear liquid sees through filter core and enters upper barrel body, and the solid matter in liquid is trapped within filter membrane surface, forms filter cake.
Backwash: the time discharge opeing with the several seconds forms negative pressure, makes that clear liquid is counter to flow, and filter cake is all come off from filter membrane surface.
Deslagging: the filter cake that departs from filter membrane surface after backwash is deposited on filter pump housing bottom, when reaching a certain amount of, is discharged rapidly automatically,
Circulating filtration: filter with the continuous cycle alternation of backwash and carry out, realized the continuous operation of filter pump.
Automatic back-washing surface filtration pump is comprised of upper barrel body, lower entire body, filter element, card, Air control valve, controller and related accessory, and filtration system, backwashing system, dreg removing system, automatic control system are reasonably combined as a whole.
Filter pressure is low: automatic back-washing surface filtration pump is positive press filtration, and filter pressure all can work within the scope of 0.05Mpa-0.15MPa.
Filter area is wide: 20ppm(0.002%)-100000ppm(10%) the liquid solid content of scope all can effectively be filtered and remove.
Adaptive temperature is high: 100 ℃ of following liquid filterings, equipment normal operation.
Chemical stability is good: acid and alkali resistance well, salting liquid corrode, and have which chemical stability.
Automaticity is high: automatic back-washing surface filtration pump is to utilize the clear liquid self filtering to complete backwash process, during backwash, do not need emptying filter pump, backwash process can complete within the several seconds, backwash finishes rear filter pump and can filter again, the filter residue that backwash is got off is discharged by slag-drip opening, and whole process completes control automatically by computer.
Life-span is long, cost is low: automatic back-washing surface filtration pump adopts extraordinary filter membrane, and filter membrane long service life reduces maintenance cost: owing to adopting low press filtration, equipment energy consumption is low, and use cost also greatly reduces.
Volume is little, take up an area and economize: automatic back-washing surface filtration pump floor space used be only same treatment traditional filtering device 1/10th, the volume of filter pump is also less than other filter.
Embodiment recited above is described preferred embodiment of the present utility model; various modification and the improvement not the technical scheme of design of the present utility model made; all should fall into protection domain of the present utility model, the technology contents that the utility model is asked for protection is all documented in claims.
