Abstract
The utility model relates to the technical field of cement impurity filtering devices, and discloses an oil well cement filtering device, which comprises a filtering barrel, a first filter screen, a second filter screen and a third filter screen, wherein the first, second and third filter screens are fixedly and sequentially arranged in the filtering barrel from left to right at intervals; and the second and third filter screens are magnetic. The oil well cement filtering device is reasonable in structure and convenient to use; and cement flowing from an ash conveying pipeline is filtered for three times through the three filter screens, and the impurity content of the filtered cement is reduced, so that the safety of cementing operation is improved.
Description
Technical field
The utility model relates to cement device for filtering impurities technical field, especially a kind of oil-well cement filter.
Background technology
Oil-well cement is the main raw material(s) of oil well cementing operation, oil-well cement has impurity such as paper scrap, plastic skin and ironwork after doing and mixing, when entering with cement, impurity gently then cause in the site operation cementing truck high pressure line acutely to be beated, heavy then cause cementing operation to interrupt, have a strong impact on cementing operation quality and safety.
Summary of the invention
The utility model provides a kind of oil-well cement filter, has overcome the deficiency of above-mentioned prior art, and it can effectively solve the problem that is mixed with impurity in the oil-well cement and has potential safety hazard.
The technical solution of the utility model is achieved like this: a kind of oil-well cement filter comprises filtration barrel body, first screen pack, second screen pack and the 3rd screen pack; In filtration barrel body from left to right in regular turn fixed interval first screen pack, second screen pack and the 3rd screen pack are installed, second screen pack and the 3rd screen pack are magnetic filtration screen.
The narrow taper in wide both sides in the middle of the two ends of above-mentioned filtration barrel body are.
The two ends of above-mentioned filtration barrel body are fixed with snap joint.
Above-mentioned first screen pack, second screen pack and the 3rd screen pack are the intersecting parallels network structure.
The utility model is rational in infrastructure, and is easy to use; To carry out three times from the cement that ash conveying pipe flows out by three screen packs and filter, the impure amount of the cement after the filtration reduces, and has therefore improved the security of cementing operation.
Description of drawings
Fig. 1 is a main TV structure schematic diagram of the present utility model.
Coding among the figure is respectively: 1 is filtration barrel body, and 2 is first screen pack, and 3 is second screen pack, and 4 is the 3rd screen pack, and 5 are snap joint.
The specific embodiment
As shown in Figure 1, this oil-well cement filter comprises filtration barrel body 1, first screen pack 2, second screen pack 3 and the 3rd screen pack 4; In filtration barrel body 1 from left to right in regular turn fixed interval first screen pack 2, second screen pack 3 and the 3rd screen pack 4, the second screen packs 3 are installed and the 3rd screen pack 4 is a magnetic filtration screen.With the utility model by being fixedly mounted between ash conveying pipe and the ash can, be used for and filter from the cement that ash conveying pipe flows into ash can, to carry out three times from the cement that ash conveying pipe flows out by three screen packs filters, the impure amount of cement after the filtration reduces, and has therefore improved the security of cementing operation.Second screen pack 3 and the 3rd screen pack 4 can adsorb tiny metal impurities for magnetic filtration screen by magnetic force.
As shown in Figure 1, the narrow taper in wide both sides in the middle of the two ends of filtration barrel body 1 are.The middle part of filtration barrel body 1 is bigger than two ends like this, and therefore first screen pack 2, second screen pack 3 and the 3rd screen pack 4 areas increase, thereby does not influence the inflow-rate of water turbine of cement, and difficult generation is suppressed stifled.
As required, the two ends of filtration barrel body 1 are fixed with snap joint 5.Be convenient to like this be connected fast with ash can with ash conveying pipe.Existing known snap joint is adopted in snap joint 5
As required, first screen pack 2, second screen pack 3 and the 3rd screen pack 4 are the intersecting parallels network structure.Adopt the intersecting parallels network structure can improve filter effect.
