Problems solved by technology

According to statistics, about 90% to 95% of commodities are transported by ships; the development of the shipping industry has brought great challenges to the ecological environment of water bodies. According to the definition of IMO, ship sewage can be divided into two categories: domestic sewage and oily sewage. Domestic sewage Including black water and gray water (kitchen gray water, washing gray water), oily sewage including bilge oily sewage, oil tank ballast water, tank washing water; ship sewage can cause marine eutrophication, crude oil leakage, migration of harmful organisms, etc. In addition, because sewage contains oil, nitrogen, phosphorus and other elements, it will consume dissolved oxygen in water, causing red tide phenomenon, threatening the survival of most aquatic organisms and affecting the ecological balance in the ocean.

Embodiment 1

[0024] Such as Figure 1-4 As shown, the ship's domestic sewage filtering device includes a mixing tank 4 and a purification tank 14. The inside of the mixing tank 4 is provided with a filter bin 19 and a sewage bin 6 from top to bottom. The water outlet 3, the water outlet 20, the water outlet 20 is connected to the purification tank 14 through the connecting pipe a11, the filter chamber 19 is equipped with a filter device 5, the filter device 5 includes a stirring shaft 508, the stirring shaft 508 is hollow inside and has a flow guide channel 505 , through holes 506 are evenly opened on the side wall of the guide channel 505 . When the device is working, domestic sewage enters the filter chamber 19 in the mixing tank 4 from the water inlet 3, and the filter device 5 in the filter chamber 19 stirs and filters the sewage, and the filtered water is discharged to the purification tank 14 through the water outlet 20 through the connecting pipe a There are two treatment methods a...

Embodiment 2

[0036] When the marine sewage filtering device of the present invention is actually used: the domestic sewage enters the filter chamber 19 in the mixing tank 4 from the water inlet 3, the filter device 5 in the filter chamber 19 stirs and filters the sewage, and the filtered water passes through the water outlet 20 It is discharged to the purification tank 14 through the connecting pipe a. After the purification tank 14 further purifies the water body, there are two treatment methods. One: through the work of the water pump 12, the high-pressure water flows into the water storage box 2 through the connecting pipe b, and then flows into the hollow design. The diversion channel 505 in the stirring shaft 508 is sprayed to the inner wall of the mixing tank 4 through the through holes 506 evenly opened on the side wall of the diversion channel 505, and the cleaning component completes the cleaning of the inner wall of the purification tank 4, which can avoid long-term accumulation of...

Abstract

The invention discloses a marine domestic sewage filtering device. The marine domestic sewage filtering device comprises a mixing tank and a purifying tank, a filtering cabin and a discharging cabin are arranged inside the mixing tank from top to bottom, a water inlet and a water outlet which are communicated with the filtering cabin are respectively formed in a left side and a right side of the mixing tank, the water outlet is connected with the purifying tank through a connection tube a, a filtering unit is mounted in the filtering cabin and comprises a stirring shaft, the stirring shaft isinternally hollow and provided with a flow guiding channel, and communication holes are evenly formed in a sidewall of the flow guiding channel. The marine domestic sewage filtering device is capableof purifying sewage in batches, reducing water resource waste and benefiting later-period collection and treatment of a water body.

Description

technical field [0001] The invention relates to the technical field of ship sewage discharge equipment, in particular to a filter device for ship domestic sewage. Background technique [0002] Ship, the general term for all kinds of ships; a ship is a means of transportation that can sail or berth in waters for transportation or operation, and has different technical performance, equipment and structural types according to different use requirements; according to different uses, the volume of ships also varies. It varies. Generally, large ships are equipped with domestic sewage filtration devices. [0003] In recent years, due to the increase of transportation costs, the proportion of the shipping industry in international commercial transportation has increased year by year. According to statistics, about 90% to 95% of commodities are transported by ships; the development of the shipping industry has brought great challenges to the ecological environment of water bodies. A...
