Description

A kind of offshore platform floor drain apparatus

Technical field

The present invention relates to Offshore Engineering technical fields, specifically disclose a kind of offshore platform floor drain apparatus.

Background technology

Traditional offshore platform deck floor drain, floor drain body are included top and are formed for one using steel plate welding Square sink, sink has been placed above grid, and lower part connects a drainpipe, and inside sets a pipe cap, to prevent downcomer Gas with foreign flavor overflow, since existing floor drain is formed using steel plate welding, welding workload is larger, in Portion's structure easily generates sludge accumulation dead angle and is not easily cleaned, and since it does not design the filter elements such as anti-sundries, silt and welding slag, So that, the construction sundries such as welding slag, iron filings easily enters pipeline by floor drain, in addition in the platform well drilling phase in platform in the construction process Between, go into operation after also have the sundries such as silt and enter floor drain, thus, the problems such as often resulting in line clogging.

The content of the invention

The object of the present invention is to provide a kind of offshore platform floor drain apparatus, which raises cleaning efficiency, reduce by In the security risk that the blocking of floor drain pipeline is replaced and brought, guarantor is provided for platform pipe-line system long period safe operation Card.

To achieve these goals, present invention employs following technical solutions：A kind of offshore platform floor drain apparatus, Including floor drain body, grid is provided on the floor drain body, the floor drain body lower part is provided with a downcomer, describedly One strainer is installed, the strainer includes outer filter and inner filter screen, the internal layer filter between leakage body and the grid Online filter opening is the square hole of (1.5~2) mm × (10~20) cm, and the short edge of adjacent two rows of square holes is staggeredly arranged, The aperture of filter opening on the outer filter is the round hole of 1~1.5mm, is maintained between the outer filter and inner filter screen Gap and be formed with filter chamber, the lid above the downcomer is equipped with a handle there are one pipe cap, on the pipe cap, describedly The semicircular structure that body is a upper end opening, both ends and perimeter seal is leaked, the downcomer is equipped with to hold up pipe cap Baffle makes sewage flow into collector nozzle.

Further, the minimum range at filter opening edge described in arbitrary neighborhood is 1~1.5mm on the outer filter.

Further, the floor drain body is tied using semi-circular tube and semi-circular sheet steel and pipe welding into semicircle Structure.

Further, the pipe cap is hemispherical.

Further, the downcomer is connected into the pipe network that begins to rehearse, into the tank that begins to rehearse.

The beneficial effects of the present invention are：The welding workload of floor drain body is effectively reduced, since structure is Semicircle is not likely to produce sludge accumulation dead angle, reduces sewage resistance, and it is easy that the setting of strainer efficiently solves sundries in sewage Pipe problems are blocked into floor drain, reduces floor drain dredging number, improves cleaning efficiency, are reduced since floor drain pipeline blocks up The security risk that row is replaced and brought is filled in, platform pipe-line system long period safe operation is ensure that, is no longer flowed when sewage When, the liquid gap between enclosed body and downcomer and hemispherical cover board under gravity, effectively prevents in body Stopped gas with foreign flavor in downcomer, oil gas returns water and enters upper deck problem, reached health, the requirement of safety and environmental protection.

Description of the drawings

Technical solution in order to illustrate the embodiments of the present invention more clearly, below will be to needed in embodiment description Attached drawing is briefly described, it should be apparent that, the accompanying drawings in the following description is only the present invention in order to illustrate more clearly of this hair Bright embodiment or technical solution of the prior art, below will be p- required for describing the embodiments or the prior art attached Figure is briefly described, for those of ordinary skill in the art, without creative efforts, can be with root Other attached drawings are obtained according to these attached drawings.

Fig. 1 is the structural diagram of the present invention.

Specific embodiment

Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, those of ordinary skill in the art are obtained every other without creative efforts Embodiment belongs to the scope of protection of the invention.

A kind of offshore platform floor drain apparatus as shown in Figure 1, including floor drain body 2, is set on the floor drain body 2 There is grid, 2 lower part of floor drain body is provided with a downcomer, one is equipped between the floor drain body 2 and the grid Strainer 1, the strainer 1 include outer filter and inner filter screen, and the filter opening on the inner filter screen is (1.5~2) mm × (10 ~20) square hole of cm, and the short edge of adjacent two rows of square holes is staggeredly arranged, the aperture of the filter opening on the outer filter is The round hole of 1~1.5mm maintains gap between the outer filter and inner filter screen and is formed with filter chamber, the lower water Pipe lid above is equipped with a handle there are one pipe cap on the pipe cap, the floor drain body 2 is a upper end opening, both ends and The semicircular structure of perimeter seal, the downcomer are equipped with to hold up the baffle of pipe cap, sewage are made to flow into collector nozzle, effectively Ground reduces the welding workload of floor drain body, since structure is semicircle, is not likely to produce sludge accumulation dead angle, reduces Sewage resistance, the setting of strainer 1 efficiently solve sundries in sewage and easily block pipe problems into floor drain, reduce floor drain Dredging number, improves cleaning efficiency, reduces the security risk replaced and brought due to the blocking of floor drain pipeline.

On the outer filter minimum range at filter opening edge described in arbitrary neighborhood be 1~1.5mm, the floor drain body 2 Using semi-circular tube and semi-circular sheet steel and pipe welding into semicircular structure, the pipe cap is hemispherical, the lower water Pipe is connected into the pipe network that begins to rehearse, and into the tank that begins to rehearse, when use enters floor drain body 2 containing miscellaneous sewage on deck by strainer, Since downcomer top edge is higher than 2 bottom surface of floor drain body, so as to form the water of certain altitude, sewage water fluid pressure and Siphonage effect is lower to be discharged by downcomer, when it is daily enter floor drain body containing miscellaneous sewage when, will be entered by downcomer and opened Tank is arranged, in addition when sewage no longer flows, under gravity, closing floor drain body 2 is under for liquid in floor drain body Gap between water pipe and hemispherical pipe cap, effectively prevents downcomer peculiar smell gas, mosquito returns water and enters upper deck, reaches The requirement of hygienic environment-protecting is arrived.

The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention With within principle, any modifications, equivalent replacements and improvements are made should all be included in the protection scope of the present invention god.
