Description

Technical Field

[0001] This application relates to the technical field of pumps, and in particular to an anti-clogging pump. Background Technology

[0002] With land-based resource development nearing saturation, deep-sea mineral resource development has become a crucial strategic direction for meeting the needs of modern society. Approximately 71% of the Earth's surface is covered by oceans, whose bottoms contain abundant strategic resources such as polymetallic nodules and rare earth elements. Deep-sea mining pumps, as core equipment in deep-sea mineral resource development, exhibit typical solid-liquid two-phase flow characteristics, involving complex fluid-structure interaction. As a critical power transmission device in deep-sea mining systems, their flow stability directly impacts the reliability and operational efficiency of the entire mining system, becoming a key technological bottleneck restricting deep-sea resource development.

[0003] Due to the operating environment, deep-sea mining pumps are prone to drawing in large mineral particles. Because the impeller guide vane flow channels are narrow, flow channel blockage frequently occurs within the pump. Furthermore, in practical applications of deep-sea mining pumps, to reduce the impact of mineral particles on the pump's rotating components, guide vanes, and walls, and to extend the pump's service life, operation is often performed under low flow rate conditions. However, under low flow rate conditions, stall phenomena can easily occur within the pump, generating stall vortices. These stall vortices, coupled with the mineral particles, can block the flow channels, leading to a reduction in the deep-sea mining pump's conveying efficiency. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, one of the objectives of this application is to provide an anti-clogging pump that has the advantage of improving the pump's delivery efficiency.

[0005] The above-mentioned objective of this application is achieved through the following technical solution:

[0006] An anti-clogging pump includes a pump body, an elimination device, and a detection unit. The detection unit is used to detect whether there is any interference phenomenon in the pump body. The interference phenomenon includes stall vortices and / or particle agglomeration clusters. If interference phenomenon exists, the elimination device eliminates the interference phenomenon.

[0007] By adopting the above technical solution, interference phenomena can be detected and eliminated during use, thereby improving the pump's delivery efficiency.

[0015] By adopting the above technical solution, the presence of the delivery pipe and valve ensures that the disturbance phenomenon in the pump body is only impacted when impact is required, thereby reducing the impact on the movement of water in the pump.

[0016] In a preferred embodiment, this application may be further configured such that the inlet pipe is provided with a filter assembly for filtering the liquid entering the delivery pipe.

[0017] By adopting the above technical solution, the presence of the filter component enables water filtration, reducing the probability of blockage in delivery pipes or spray pipes.

[0019] By adopting the above technical solution, large particles are crushed when they are present, thereby reducing the probability of large particles entering the pump body.

[0020] In a preferred embodiment, the present application may be further configured such that there are multiple sets of the pulverizing device arranged along the axial direction of the water inlet pipe.

[0021] By adopting the above technical solution, multiple sets of crushing devices have a better crushing effect on large particles.

[0022] In a preferred embodiment, the present application may be further configured such that the pulverizing device includes a cutting blade and a drive member for extending and retracting the cutting blade, wherein the distance extended by the plurality of cutting blades gradually increases along the direction toward the water inlet.
