Description

Technical Field

[0001] The utility model relates to a sewage lifting device for dock ships, belonging to the technical field of sewage treatment equipment. Background Art

[0002] Inland vessels all need to consider how to deal with sewage discharge to avoid pollution of the river. Preventing and controlling ship pollution and protecting the water environment are important issues facing both the international and domestic governments. According to the current sewage discharge requirements for inland ships in my country, ships sailing on rivers cannot discharge the generated sewage directly into the waters, but need to transfer it to the sewage treatment system on the shore and treat it to meet environmental protection standards before it can be discharged. Therefore, the wastewater generated by ships sailing on rivers needs to be collected in the ship's sewage tank first. When the ship is moored at the dock on the river, the sewage on the ship is pumped into the sewage treatment system on the dock platform through a sewage pump to empty the volume of the ship's sewage tank. The oily sewage and domestic sewage of ships at the port are generally transported to shore through pipelines using the cargo ship's own sewage pump.

[0003] However, there are often a lot of solid impurities in the sewage in the ship's sewage tank, which easily causes the solid impurities to settle at the bottom of the sewage tank, making it difficult to clean and causing trouble for users. Now there is an urgent need for a dock ship sewage lifting device to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model aims to provide a dock ship sewage lifting device to solve the problems raised in the above-mentioned background technology. The utility model has a built-in stirring and scraping structure in the ship-borne sewage tank, which can rotate and scrape away the solid impurities precipitated in the sewage. At the same time, in conjunction with the filtering and sewage pump structure, the solid impurities in the sewage can be filtered and collected to prevent them from subsequently affecting the sewage lifting effect of the sewage pump.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a dock ship sewage lifting device, comprising a ship-borne sewage tank, rotating blades and a filter box, a stirring motor is installed in the middle of the upper end of the ship-borne sewage tank, a cross metal seat is installed at the lower end of the ship-borne sewage tank, a reinforcement base is installed at the lower end of the cross metal seat, a plurality of rotating blades are provided, and the plurality of rotating blades are all transmission-connected to the shaft end of the stirring motor, two spiral blades are staggeredly installed between the plurality of rotating blades, lateral scrapers are installed at the left and right ends of the plurality of rotating blades, bottom scrapers are installed at the lower ends of the plurality of rotating blades, a filter box is placed on the upper end of the reinforcement base, a filter mesh is horizontally fixed in the filter box, a sewage pump is installed at the right end of the filter box, and a lifting pipe is installed at the discharge end of the sewage pump.

[0006] Furthermore, a sewage inlet pipe is installed through the left side of the upper end of the ship-borne sewage tank.

[0007] Furthermore, the plurality of lateral scrapers are all slidably attached to the inner wall of the ship's sewage tank.

[0008] Furthermore, the bottom scraper is slidably attached to the lower end of the inner wall of the ship-borne sewage tank.

[0009] Furthermore, the upper end of the filter box is connected to the sewage discharge end of the lower end of the ship's sewage tank.

[0010] Furthermore, a detachable waterproof cover is installed on the upper side of the front end of the filter box by bolts.

[0011] The beneficial effects of the utility model: the utility model is a dock ship sewage lifting device. Because the utility model adds a stirring motor, rotating blades, spiral blades, side scrapers, bottom scrapers, filter box, filter mesh, sewage pump and detachable waterproof cover, our design improvement and actual use have shown that the device has a reasonable structure and good practicality. The stirring and scraping structure is built into the ship-borne sewage tank, which can rotate and scrape away the solid impurities precipitated in the sewage. At the same time, in conjunction with the filtering and sewage pump structure, the solid impurities in the sewage can be filtered and collected to prevent them from subsequently affecting the sewage lifting effect of the sewage pump.

[0019] As the first embodiment of the utility model: a sewage inlet pipe 2 is installed through the left side of the upper end of the ship-borne sewage tank 1. Through the added sewage inlet pipe 2, it is convenient for ship personnel to discharge the sewage on the ship into the ship-borne sewage tank 1. Multiple side scrapers 8 are slidably attached to the inner wall of the ship-borne sewage tank 1. When the added multiple side scrapers 8 are driven to rotate, the solid impurities precipitated on the inner wall of the ship-borne sewage tank 1 can be rotated and scraped off. The bottom scraper 9 is slidably attached to the lower end of the inner wall of the ship-borne sewage tank 1. When the added bottom scraper 9 is driven to rotate, the solid impurities precipitated on the lower end of the inner wall of the ship-borne sewage tank 1 can be rotated and scraped off.

[0020] The upper end of the filter box 10 is connected to the sewage discharge end of the lower end of the ship-borne sewage tank 1. The added filter mesh 11 can filter and intercept solid impurities in the sewage when it is discharged from the ship-borne sewage tank 1. A detachable waterproof cover 14 is bolted to the upper side of the front end of the filter box 10. The added detachable waterproof cover 14 makes it easy for the staff to unscrew the outer bolts with an external wrench, and then open the filter box 10 to clean the solid impurities filtered by the filter mesh 11.

[0021] As the second embodiment of the utility model: in actual use, the added sewage inlet pipe 2 is convenient for the ship personnel to discharge the sewage on the ship into the ship-borne sewage tank 1. When the sewage in the ship-borne sewage tank 1 needs to be lifted and discharged, the stirring motor 5 is started. The stirring motor 5 can drive multiple rotating blades 6, two spiral blades 7, two side scrapers 8 and the bottom scraper 9 to rotate, so that the sewage in the ship-borne sewage tank 1 can be mobilized for rotation and stirring. At the same time, the solid impurities precipitated on the inner wall and the lower end surface of the ship-borne sewage tank 1 can be rotated and scraped off. Then the sewage pump 12 is started. The sewage pumping end of the sewage pump 12 draws away the sewage in the ship-borne sewage tank 1 through the filter box 10, and discharges it to the dock through the lifting pipe 13. The filter mesh 11 can filter and intercept the solid impurities in the sewage in the ship-borne sewage tank 1 when the sewage is discharged, so as to facilitate subsequent cleaning by the ship personnel.
