Description

Technical Field

[0001] The present invention relates to sewage treatment, and in particular to a ship sewage treatment device with self - circulating energy. Background Art

[0002] During the operation of a ship, a large amount of wastewater is generated when cleaning the ship's deck or floor. Compared with kitchen and toilet sewage, this wastewater is relatively less polluted, but there are many problems with existing treatment methods. Currently, ship deck sewage often contains sand and a small amount of engine oil. In the prior art, the sewage is often passed into a filtering mechanism, and the sand is filtered by a filter plate. Its working principle is that when the sewage passes through the filter plate, large - particle substances such as sand are intercepted on one side of the filter plate, thus achieving preliminary filtration. However, during long - term operation, as the sand accumulates continuously and the engine oil adheres, the pores of the filter plate are gradually blocked, making it difficult to perform effective filtration and resulting in a deterioration of the filtration effect. At the same time, inside a ship where fresh water resources are scarce, if this sewage is directly introduced into the sewage treatment system for discharge or directly discharged, it will cause a large waste of fresh water resources.

[0003] After retrieval, the authorized announcement number CN210620523U discloses a multi - stage domestic sewage treatment device, which specifically discloses: including a first treatment tank and a second treatment tank, a filter screen is obliquely arranged on the inner wall of the first treatment tank, a slag discharge port is opened on one side of the first treatment tank where the filter screen is fixed, a movable plate is installed on the slag discharge port, the movable plate is slidably connected to the first treatment tank, a handle is fixed on the side of the movable plate, a spring is fixed between the top of the movable plate and the first treatment tank, a waste residue tank is fixed on the side of the first treatment tank, and the waste residue tank is communicated with the first treatment tank through the slag discharge port.

[0037] The working process of the present invention is as follows:

[0038] Install the present invention at a suitable position on the ship to ensure that the water inlet pipe 6 is connected to the ship's sewage discharge source, and the discharge pipe 12 leads to the area where the ship's available water resources are located. When the ship generates sewage, the sewage flows into the treatment tank 5 through the water inlet pipe 6. The inclined sieve plate in the treatment tank 5 can pre-treat the sewage, filter out the sand and large-particle sundries in it, and clean the sieve plate through the second cleaning component, scraping the sundries such as sand on the sieve plate to avoid clogging of the sieve plate and improve the filtering effect of the sieve plate; the filtered sewage enters the tank body 1, and the oil in the sewage is further filtered through the filter screen inside the fixing plate 2. At the same time, the first cleaning component can clean the filter plate in all directions to ensure its filtering effect, so as to realize the automatic treatment of sewage. At the same time, the solar panel 10 converts light energy into electrical energy and stores it in the storage battery 20 to supply power to the first motor 13 and the second motor 14. The first motor 13 drives the first scraper 32 and the second scraper 33 to rotate and work to clean the filter plate; the second motor 14 drives the brush plate 16 to clean the sieve plate, and the brush plate 16 scrapes the sundries such as settings through the slag discharge port 18 into the slag discharge box. The slag discharge box is inclined, so that the sand rolls into the collection box 7 under the action of gravity. The collection cabinet 19 slidably connected to the inner wall of the collection box 7 can collect the sand, and the collection cabinet 19 can be easily pulled out through the handle for subsequent cleaning of the sundries. The filtered sewage is discharged through the discharge pipe 12 for the ship to use, and the sundries in the collection cabinet 19 in the collection box 7 can be periodically pulled out through the handle for cleaning. The solar panel 10 installed on the top of the fixing frame 9 triggers the photovoltaic effect, converts light energy into electrical energy and stores it in the storage battery 20, and the inverter 21 converts the direct current in the storage battery 20 into alternating current to provide electrical energy for the first motor 13 and the second motor 14, realizing the energy self-circulation, reducing the operation cost of the device, and conforming to the environmental protection concept.
