Abstract
The utility model provides a compound basket filter filter core, including straining the basket, strain the basket and make by the board that punches a hole, should strain and be provided with three -dimensional compound filter screen in the basket, three -dimensional compound filter screen includes coarse filter layer and thin filtering layer that from interior to exterior set up, coarse filter layer filtration pore aperture is greater than thin filtering layer filtration pore aperture, coarse filter layer strains porosity and is less than thin filtering layer and strains porosity, three -dimensional compound filter screen with strain the basket for detachable the connection. The utility model discloses increase a set of three -dimensional compound filter screen in basket filter, from the feed liquor face to going out liquid level filter fineness big -endian, by rare to close for the great dirty stifled thing of volume is piled up near the inlet is coarse filter layer, and the less dirty stifled thing of particle diameter is piled up in liquid outlet thin filtering layer department promptly, avoids the filter to stop up at the excessive speed and results in frequent cleaning or renew cartridge more, carry out the depth -type filtration to the medium, this three -dimensional compound filter screen can be dismantled and use repeatedly, rinses clearance convenient operation, has reduced the work load of safeguarding, has lengthened filter life.
Description
Technical field
The utility model belongs to petrochemical industry process field, especially relates to a kind of compound basket filter filter core.
Background technology
At present, sea water service system is responsible for the important tasks such as power-equipment cooling, fire-fighting and daily sea water supply, and be one of important system of offshore oilfield, its middle filtrator is the important component part of sea water service system.Generally, containing silt, algae, microorganism and other impurity etc. in seawater, when seawater is by filter, inevitably in filter basket, accumulate dirt, the accumulation of long algae, shell or microorganism corpse even, these materials can produce corrosion to filter basket after piling up in filter basket, blocking filter basket and not easy to clean.
Simultaneously, in order to improve the polymer injection or transfer drive operation that recovery ratio takes, in the later stage produces, have the long-chain molecules such as partial polymer output successively, these large molecule backbones are gathered in production handling process, cause frequent clean filter screen, increase on-the-spot workload.In addition, all there is Similar Problems in other media etc. relating to filtration.
Summary of the invention
It is simple that problem to be solved in the utility model is to provide a kind of structure, and it is convenient to dismantle, easy to clean, the too fast blocking of filter is avoided to cause frequent clean or more renew cartridge, filter effect is desirable, and pollutant holding capability is large, extends the compound basket filter filter core in filter basket service life.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of compound basket filter filter core, comprise filter basket, described filter basket is obtained by punched-plate, be provided with three-dimensional composite screen in this filter basket, described three-dimensional composite screen comprises by the coarse filtration layer arranged outside interior and fine filtering layer.
Aperture, described coarse filtration metafiltration hole is greater than aperture, fine filtering metafiltration hole.
Described coarse filtration metafiltration hole density is less than fine filtering metafiltration hole density.
Described three-dimensional composite screen and filter basket are detachable connection.
Owing to adopting technique scheme, the utility model increases by one group of three-dimensional composite screen in basket filter, this composite screen is the multistage individual layer filter screen arranged by different filtering accuracy, descending to going out liquid level filtering accuracy from feed liquor face, by rare to close, the dirty stifled thing making volume larger is deposited near inlet and coarse filtration layer, the dirty stifled thing that particle diameter is less is deposited in liquid outlet and fine filtering layer place, effective categorised collection has been carried out to dirty stifled thing, extend service time, avoid the too fast blocking of filter to cause frequent clean or more renew cartridge; The dirty stifled thing such as marine growth or large molecule backbone in basket filter is more easily cleaned out, and carry out depth-type filtration to medium, pollutant holding capability increases.
The detachable Reusability of this three-dimensional composite screen, cleaning cleaning operation is convenient, decreases the workload of maintenance, extends filter service life.
The beneficial effects of the utility model are: have structure simple, it is convenient to dismantle, easy to clean, and avoid the too fast blocking of filter to cause frequent clean or more renew cartridge, filter effect is desirable, and pollutant holding capability is large, extends the advantage in filter basket service life.
Accompanying drawing explanation
Below by with reference to accompanying drawing describe the utility model particularly in conjunction with example, advantage of the present utility model and implementation will be more obvious, wherein content shown in accompanying drawing is only for explanation explanation of the present utility model, and do not form restriction of going up in all senses of the present utility model, in the accompanying drawings:
Fig. 1 is structural representation of the present utility model
In figure:
Detailed description of the invention
As shown in Figure 1, a kind of compound basket filter filter core of the utility model, comprise filter basket, described filter basket is obtained by punched-plate 1, be provided with three-dimensional composite screen 2 in this filter basket, described three-dimensional composite screen comprises by the coarse filtration layer 21 arranged outside interior and fine filtering layer 22; Described coarse filtration layer 21 filter opening aperture is greater than fine filtering layer 22 filter opening aperture; Described coarse filtration layer 21 filter opening density is less than fine filtering layer 22 filter opening density; Described three-dimensional composite screen 2 and filter basket are detachable connection.
The utility model increases by one group of three-dimensional composite screen 2 in basket filter, thickness at least reaches 2 to 3cm, for 20 to 30 times (can also customize further as required and thicken) of conventional bowl, this composite screen is the multistage individual layer filter screen arranged by different filtering accuracy, descending to going out liquid level filtering accuracy from feed liquor face, by rare to close, the dirty stifled thing making volume larger is deposited near inlet and coarse filtration layer 21, the dirty stifled thing that particle diameter is less is deposited in liquid outlet and fine filtering layer 22 place, effective categorised collection has been carried out to dirty stifled thing, extend service time, the too fast blocking of filter is avoided to cause frequent clean or more renew cartridge, the dirty stifled thing such as marine growth or large molecule backbone in basket filter is more easily cleaned out, and carry out depth-type filtration to medium, pollutant holding capability increases, the detachable Reusability of this three-dimensional composite screen 2, cleaning cleaning operation is convenient, decreases the workload of maintenance, extends filter service life.
Above embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model scope change and improve, and all should still belong within this patent covering scope.
