[0002] Sludge is a sediment formed in an environment with slow water flow, such as a bay, a lake, or a river bay, through the participation of microorganisms. The accumulation of a large amount of sludge can cause many hazards to the water body. For example, the accumulation of sludge can raise the river bottom, reduce the water capacity, increase the water temperature change, and be not conducive to the growth of aquatic organisms.

[0003] In the traditional sludge mud treatment mode, sludge mud is usually sucked onto the shore, and then filtered and treated in fixed treatment facilities. This mode is effective when dealing with small-scale or relatively limited water area sludge problems; however, when facing vast waters, such as large lakes, rivers, or oceans, this mode is not only time-consuming and labor-intensive, but also inefficient.

[0033] Example 1

[0034] like Figs. 1-3 As shown, this embodiment provides a ship hull mud filtration device (hereinafter referred to as "this device"), including: a debris removal tank 1, a support component 2, N sets of mud screening components 3, and an impurity output component. This device is installed on the ship hull and is used for filtering silt and mud.

[0035] The impurity removal tank 1 is installed on the hull. The impurity removal tank 1 contains receiving troughs. The number of receiving troughs is the same as the number of mud screening components 3. In this embodiment, there are two sets of mud screening components 3, therefore, there are two sets of receiving troughs in the impurity removal tank 1. The receiving troughs are used to hold the filtered mud.

[0036] The support component 2 is laid on top of the impurity removal tank 1. The support component includes a support section and N sets of screening sections. The support section is configured to support the slurry screening assembly. The screening sections are mesh plates used for further screening of the slurry. The mesh size of the mesh plates is determined based on actual needs. The screening sections are positioned above the receiving tank.

[0037] N sets of mud screening components 3 are mounted on the support 2. Each mud screening component 3 has a mud input end, a mud output end, and an impurity output end 35. The mud output end is located at the bottom of the mud screening component 3, above the screening section. In other words, the mud filtered by the mud screening component 3 passes sequentially through the mud output end and the screening section before moving into the receiving tank.

[0038] The mud screening assembly 3 is a multi-stage screening mechanism. After being screened by the multi-stage screening mechanism, the mud flows into the containing groove. In this embodiment, the mud screening assembly 3 adopts a multi-stage linear vibrating screening machine. Specifically, the mud screening assembly 3 includes a screening body 31, at least two stages of screening meshes 32, a cross beam 33, and a power source 34. The screening body 31 is provided with a screening space. The bottom of the screening body 31 is provided with a mud output end. The at least two stages of screening meshes 32 are arranged in the screening body 31 in an upper and lower manner. The cross beam 33 is installed on the top of the screening body 31. The power source 34 is a driving motor, and the power source 34 is installed on the cross beam 33. The multi-stage linear vibrating screening machine adopts a double-layer or multi-layer screen mesh design. The mesh diameters of each layer of screen meshes are different. The appropriate mesh diameters are selected according to the needs to filter the mud and impurities. This helps to improve the screening precision and ensure that the filtered mud and impurities meet specific quality requirements. The multi-stage linear vibrating screening machine can efficiently realize the screening and grading of the mud and impurities. Impurities of different particle sizes are distributed on different screen meshes, thereby realizing accurate separation. Compared with the prior art of one-stage screening (the mesh hole is very fine), considering that the amount of mud is large and is easy to cause blockage, the multi-stage screening form is adopted in this embodiment.

[0039] The impurity conveying assembly is connected with the impurity output end 35. The impurities obtained by each stage of screening are output from the impurity output end 35 to the impurity conveying assembly. The impurity conveying assembly can adopt a conveying belt. The impurity conveying assembly conveys the impurities output from the impurity output end 35 to another water transportation carrier, such as a floating platform or a ship structure. The impurity conveying assembly can automatically and continuously convey the impurities from the impurity output end 35 to the water transportation carrier, avoiding the cumbersome process of manual collection and transportation. Conveying the impurities to the water transportation carrier facilitates subsequent classification, processing, and recycling. This helps to reduce resource waste and improve resource recycling rate.

[0040] The device also includes a mud feeding assembly 4. The mud feeding assembly 4 is arranged above the mud screening assembly 3. The mud feeding assembly 4 is arranged to transport the mud to be filtered into the mud screening assembly 3. The mud feeding assembly 4 includes a transportation main pipe 41, M groups of branch pipes 42, and a discharging member 43. The mud feeding assembly 4 is connected with an external pump body power device (the connection mode is a prior art, which is not described here) to realize the transportation of the mud in the water body to the mud screening assembly 3.

[0041] The transport main pipe 41 is installed above the mud screening assembly 3. One end of each branch pipe 42 is communicated with the transport main pipe 41, and the other end is connected with a discharging member 43. The discharging member 43 is a discharging box, which is hollow inside and has an opening at the bottom, and one side of the discharging box is communicated with the branch pipe 42. The mud to be treated is first transported to the transport main pipe 41, and then is shunted to two or more mud screening assemblies 3 through the M branch pipes 42; such shunting design can rapidly distribute the mud to each mud screening assembly 3, and such parallel processing mode can significantly improve the processing efficiency of the mud, so that the whole device can complete the filtration task more quickly; in addition, the shunting design can make the load of each mud screening assembly 3 more balanced, thereby prolonging the service life of the equipment.

[0042] After the mud is filtered and enters the containing groove, in order to facilitate subsequent processing operation, the device is provided with a rotatable stirring member in the containing groove. The stirring member is driven to rotate by a motor. The flocculating agent is added to the containing groove, the stirring member stirs the mud, accelerates flocculation, and realizes further purification of the mud. The mud treated by flocculation can be returned to the water body, reducing the pollution to the environment; this helps to maintain the ecological balance of the water body and protect the living environment of aquatic organisms.
