Dome device for oil-water-sand separation equipment

Abstract

The invention discloses a dome device for oil-water-sand separation equipment. The device structurally comprises a water outlet, a filtration obstruction device, an movable pushing rod, an activated carbon filtration device, a pedestal, a dome filtration device, a material inlet, a division plate, a running water cabin, a protection shell, a water level floating board, a pressing block and a smallfixed plate, wherein the water outlet is fixedly connected with the protection shell, the activated carbon filtration device is actively connected with the filtration obstruction device, the materialinlet is arranged below the filtration obstruction device and actively connected with the dome filtration device through the filtration obstruction device, the small fixed plate is actively connectedwith the filtration obstruction device, the filtration obstruction device is provided with the dome filtration device, with the unique dome filtration device arranged, the filtration accuracy can meet predetermined requirement, enough flow capacity can be maintained within a relatively long time, and a filter board can also has enough strength, cannot be damaged by the action of hydraulic pressure, and can further operate under stipulated temperature.

Description

technical field [0001] The invention relates to a dome device used for oil-water-sand separation equipment, which belongs to the field of oil-water-sand separation equipment. Background technique [0002] A machine for oil-water separation, which is usually used for catering to treat sewage. Due to environmental protection requirements, the sewage generated in the ship's machinery space discharged into rivers, lakes and seas must be treated, and an oil-water separator is required. [0003] The prior art discloses a dome device with the application number of CN201320326134.3 for oil-water-sand separation equipment, including a dome, which is characterized in that a round hole is opened above the dome, and the round holes are sequentially arranged from the inside to the outside. There are an inner reinforcing ring and an outer reinforcing ring, and the inner reinforcing ring and the outer reinforcing ring are fixedly connected by several vertical ribs. In the present inventio...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a dome device for oil-water-sand separation equipment to solve the problem that there is no unique dome filter device, and the filtration accuracy cannot meet the predetermined requirements and can be maintained for a long time. The flow capacity of the filter plate cannot make the filter plate have sufficient strength, not to be damaged by the hydraulic pressure, and it cannot work continuously at the specified temperature
