Abstract
Description
Technical Field
[0001] This utility model relates to the field of sewage treatment technology, and in particular to a device for treating domestic sewage from ships. Background Technology
[0002] Shipboard sewage treatment systems are crucial pollution prevention equipment on board ships. This sewage contains large amounts of pollutants such as organic matter, pathogens, and nutrients. Direct discharge without effective treatment can severely damage marine ecosystems, affecting not only the survival and reproduction of marine life but also potentially endangering human health through the food chain. Shipboard sewage treatment systems are primarily used to treat shipboard sewage to meet the discharge standards of international conventions and national laws, thereby preventing pollution of the marine environment. This equipment uses a series of physical, chemical, and biological treatment processes to treat and separate the sewage. Some countries and regions have established relevant regulations and requirements that strictly limit the discharge of shipboard sewage and impose corresponding penalties for illegal discharge. Therefore, shipboard sewage treatment systems have become an essential environmental protection device on ships.
[0003] For example, patent CN216513238U discloses a shipboard sewage treatment device, including a cabinet, a treatment box, and an electric telescopic rod. A washbasin is installed at the top of the cabinet, a conveying pipe is installed below the washbasin, and the treatment box is installed at the end of the conveying pipe. A solenoid valve is installed on the conveying pipe, and an electric telescopic rod is installed at the top center of the treatment box. The beneficial effects are: by setting up an electric telescopic rod, a pressure plate, a sieve plate, an air pump, and a solenoid valve, when food residue enters or exits the treatment box, the electric telescopic rod drives the pressure plate to squeeze the food residue, causing it to be crushed through the sieve plate. When the through holes on the sieve plate are blocked, the operator closes the solenoid valve and opens the air pump to inflate the treatment box, thereby clearing the holes on the sieve plate. This process does not generate noise and achieves the purpose of crushing food residue, thus improving the effectiveness of the device.
[0004] When using the above-mentioned technology, the following technical problems were found in the existing technology: In an existing ship sewage treatment device, the sewage and chemicals are mixed without a stirring mechanism, resulting in poor mixing of the chemicals and sewage and failing to achieve the desired sewage treatment effect. Furthermore, in an existing ship sewage treatment device, food residue is crushed by squeezing, but the crushing force is difficult to control, resulting in insufficient crushing effect and easy clogging, affecting the continuous operation of the ship sewage treatment device. Therefore, there is room for improvement. To address these issues, we designed a ship sewage treatment device to provide an alternative technical solution. Utility Model Content

[0033] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0034] Example 1
[0035] Reference Figure 1 - Figure 8A shipboard sewage treatment device includes a treatment cabinet 1, a mixing tank 2, and a separation tank 3. The mixing tank 2 is fixed to the bottom of the inner side of the treatment cabinet 1, and the separation tank 3 is fixed to one end of the inner side of the treatment cabinet 1. A chemical mixing mechanism is installed inside the mixing tank 2, and a solid-liquid separation mechanism is installed inside the separation tank 3. A crushing mechanism is installed between the treatment cabinet 1 and the separation tank 3.
[0036] The reagent mixing mechanism includes a bucket cover plate 4, a first motor 5, stirring and mixing blades 6, a disc 7, a transparent reagent cylinder 8, a sealing cap 9, and a first control valve 10. The bucket cover plate 4 is fixed to the top of the mixing bucket 2. The first motor 5 is fixed to the top of the bucket cover plate 4. The stirring and mixing blades 6 are fixed to the power output end of the first motor 5. The disc 7 is fixed to the power output end of the first motor 5 at the bottom of the bucket cover plate 4. The transparent reagent cylinder 8 is fixed to the top of the bucket cover plate 4 next to the first motor 5. The sealing cap 9 is threaded to the top of the transparent reagent cylinder 8. The first control valve 10 is fixed inside the transparent reagent cylinder 8. When reagents and domestic sewage are to be mixed... During mixing, the sealing cap 9 is opened by rotating it, and the agent is added into the transparent agent cylinder 8. Then, the sealing cap 9 is tightened by rotating it, the first control valve 10 is opened, and the first motor 5 is started. The power output end of the first motor 5 drives the stirring and mixing blades 6 to rotate. The stirring and mixing blades 6 stir the domestic sewage inside the mixing tank 2. At the same time, the power output end of the first motor 5 drives the disc 7 to rotate. Since the disc 7 has a hole at its eccentric position, and the position corresponds to the bottom position of the transparent agent cylinder 8, the agent falls once when the hole of the disc 7 rotates to the bottom of the transparent agent cylinder 8. In this way, the agent can be added intermittently while stirring, so that the sewage and the agent are fully mixed.
[0037] The crushing mechanism includes a water tank 25, a downflow pipe 26, a third motor 27, and a crushing blade 28. The water tank 25 is fixed inside the treatment cabinet 1.

The crushing blade 28 is fixed to the power output end of the third motor 27. When it is necessary to crush debris in the ship's domestic sewage, the domestic sewage on the ship is poured from the water tank 25 and flows down through the downflow pipe 26. The sewage will carry debris. In order to prevent blockage and ensure thorough mixing with the subsequent agents, the third motor 27 is started. The power output end of the third motor 27 drives the crushing blade 28 to rotate. The crushing blade 28 is equipped with two sets of crushing blades on its outside. By rotating the crushing blade 28, large-sized debris in the sewage can be crushed, making the debris smaller and effectively avoiding blockage.
[0038] A guide pipe 22 is fixed between the mixing tank 2 and the separation tank 3, and a discharge pipe 23 is fixed at the bottom of one end of the mixing tank 2. The guide pipe 22 facilitates the flow of filtered sewage into the mixing tank 2, and the discharge pipe 23 allows the treated sewage that meets the regulations to be discharged, so that the ship's domestic sewage treatment device can continue to operate and treat sewage.
[0039] Multiple mounting holes 24 are evenly distributed at the bottom of the treatment cabinet 1. Since ships sway with the waves when they are at sea, the items inside the ship can easily move. In order to ensure the stable operation of the ship's domestic sewage treatment device, screws can be passed through the mounting holes 24 to fix the device in place, so that it can operate safely and continuously treat domestic sewage.
[0040] Both ends of one side of the treatment cabinet 1 are connected to cabinet doors 29 by two hinges; the cabinet doors 29 protect the internal components of the treatment cabinet 1 from being exposed to the outside, and also make the ship's domestic sewage treatment device look neat and beautiful.
[0041] The transparent reagent cylinder 8 has a scale line 11 on one side of its exterior. The scale line 11 makes it easy to quantify the amount of reagent added into the transparent reagent cylinder 8, allowing for precise control of the amount of reagent added. This is beneficial for the scientific treatment of wastewater and results in better treatment.

[0043] Reference Figure 5 and Figure 6A shipboard sewage treatment device includes a solid-liquid separation mechanism comprising a second motor 12, a threaded screw 13, guide rods 14, a cleaning plate 15, a wire brush 16, a tank cover 17, a filter screen 18, a channel 19, a butterfly fixing screw 20, and a removable collection box 21. The second motor 12 is fixed to one end of the separation box 3, and the threaded screw 13 is fixed to the power output end of the second motor 12. One end of the threaded screw 13 is fixed to the separation box 3 via a bearing. Two guide rods 14 are fixed inside the separation box 3, and the cleaning plate 15 is threadedly connected to the outside of the threaded screw 13. Both guide rods 14 are slidably connected to the cleaning plate 15. A filter screen 18 is fixed inside the mixing tank 2, and a wire brush 16 is fixed to the bottom of the cleaning plate 15, with the wire brush 16 slidably connected to the filter screen 18. The top of the separation box 3 is fixed... The separation box 3 is fixed with a cover plate 17 and a channel 19 at the other end. One end of the channel 19 is fixed with a removable collection box 21 by two butterfly screws 20. When solid-liquid separation of debris and sewage in the ship's domestic sewage is required, the second motor 12 is started. The power output end of the second motor 12 drives the threaded screw 13 to rotate. The threaded screw 13 drives the cleaning plate 15 to slide on the surface of the guide rod 14. At the same time, the cleaning plate 15 drives the wire brush 16 to clean the surface of the filter screen 18. In this way, the debris that has not passed through the filter screen 18 can be collected and pushed into the removable collection box 21 through the channel 19 to collect solid debris. After the debris has been collected for a period of time, the removable collection box 21 can be removed by rotating the butterfly screws 20 for convenient centralized treatment of debris.

A transparent chemical cylinder 8 is fixed to the top of the bucket cover 4 next to the first motor 5, and a sealing cap 9 is threaded to the top of the transparent chemical cylinder 8. A first control valve 10 is fixed inside the transparent chemical cylinder 8. Then, by rotating to open the sealing cap 9, the chemicals are added to the transparent chemical cylinder. Inside the agent cylinder 8, the sealing cap 9 is rotated and tightened, the first control valve 10 is opened, and the first motor 5 is started. The power output end of the first motor 5 drives the stirring and mixing blades 6 to rotate, and the stirring and mixing blades 6 stir the domestic sewage inside the mixing tank 2. At the same time, the power output end of the first motor 5 drives the disc 7 to rotate. Since the disc 7 has a hole at its eccentric position, and the position corresponds to the bottom position of the transparent agent cylinder 8, when the hole of the disc 7 rotates to the bottom of the transparent agent cylinder 8, the agent falls once. In this way, the agent can be added intermittently while stirring, so that the sewage and the agent are fully stirred and mixed.

When the domestic sewage on the ship is poured from the water tank 25 and flows downward through the downflow pipe 26, the sewage will carry debris. In order to prevent blockage and to ensure thorough mixing with the subsequent chemicals, the third motor 27 is started. The power output end of the third motor 27 drives the crushing blade 28 to rotate. The crushing blade 28 is equipped with two sets of crushing blades on its outside. By rotating the crushing blade 28, large-sized debris in the sewage can be crushed, making the debris smaller and effectively avoiding blockage.

Then, the second motor 12 is started, and the power output end of the second motor 12 drives the threaded screw 13 to rotate. The threaded screw 13 drives the cleaning plate 15 to slide on the surface of the guide rod 14. At the same time, the cleaning plate 15 drives the wire brush 16 to clean the surface of the filter screen 18. In this way, the debris that has not passed through the filter screen 18 can be collected and pushed into the removable collection box 21 through channel 19 to collect solid debris.
