Floor drain for three-stage sewage separation

Abstract

The invention discloses a floor drain for three-stage sewage separation. The floor drain comprises a box, and further comprises a grating and a movable cover plate which are arranged on the box; a cover barrel is mounted in the box, a main drainage pipe and a plurality of partition plates are oppositely mounted below the cover barrel, threaded plugs and technology holes are formed in the partitionplates correspondingly, and a movable cover plate support is horizontally mounted on the corresponding partition plate; a standby drainage pipe is arranged in the box; a plurality of pieces of roundsteel are mounted on the periphery of the main drainpipe pipe and mounted on a bottom plate of the box; and the bottom plate is obliquely arranged. Sewage can be purified and separated, the problems of drainage purification and separation are solved, and the purification capability of the sewage is greatly improved; and the problems of drainage and drainage pipeline corrosion prevention are solved, the corrosion resistance of the drainage pipelines is greatly improved, and later maintenance of the drainage pipelines is convenient.

Description

technical field [0001] The invention relates to a floor drain, in particular to a floor drain used for three-stage sewage separation. It belongs to the field of marine engineering and petrochemical industry. Background technique [0002] In the development of offshore oil engineering, liquefied natural gas (LNG), and floating production storage and offloading (FPSO), floor drains are an indispensable device. If the floor drain is not designed properly, it will not only cause poor drainage, it will be difficult to meet the drainage requirements during heavy rainfall, and the accumulation of dirt may cause blockage of the drainage pipeline; moreover, it is not easy to clean. Because the existing floor drain generally adopts a single "box" funnel-shaped design, the bottom is a single drainage pipeline, and it is set with a semi-closed cover; therefore, not only the space is relatively narrow, but also when there is heavy rainfall, there are difficulties in drainage and debris....

AI Technical Summary

Problems solved by technology

[0003] The main purpose of the present invention is to overcome the above-mentioned shortcomings existing in the prior art, and to provide a three-stage sewage separation floor drain, which can not only purify and separate sewage, solve the problem of drainage purification and separation, and greatly improve the purification ability of sewage; Moreover, it solves the problem of anti-corrosion of drainage and drainage pipelines, greatly improves the anti-corrosion performance of drainage pipelines, and facilitates the later maintenance of drainage pipelines
