Description

Technical Field

[0001] This utility model relates to the technical field of water surface and tidal flat cleaning, and in particular to a shovel-type oil sludge remover, which is mainly used to clean viscous or emulsified and solidified crude oil and sludge on shores, beaches, water surfaces or sea surfaces and water surfaces in extremely cold icy areas. Background Technology

[0002] With the rapid development of global marine economic activities (shipping, oil extraction, and coastal industries), my country's dependence on petroleum raw materials remains high. This inevitably requires a large amount of oil tanker and pipeline transportation, while oil tanker accidents and pipeline ruptures frequently cause crude oil pollution. How to prevent and proactively control oil spills and prevent their spread has become a crucial issue for crude oil transshipment and pipeline transportation. Building rapid and effective recovery capabilities without compromising economic efficiency requires a deeper understanding of oil recovery operation methods in various complex environments.

[0003] Currently, oil skimmers are basically divided into three categories based on their recovery operation principles: drum skimmers or disc skimmers, which utilize high speed and viscosity, are suitable for recovering light oils; brush skimmers are suitable for recovering viscous crude oil and sludge. These three operating principles, through the addition of buoys or thrust propellers, have resulted in various forms of self-floating and self-propelled oil skimmers. However, for oil spills on the shore where the oil has mixed with silt, or for viscous crude oil spilled on the nearshore waters or sea surface that has emulsified, due to complex geographical environments such as reefs or algae, it is difficult for both self-propelled and self-floating oil skimmers to reach these areas and even more difficult to completely remove the oil clumps adhering to the silt.

[0004] With the opening of the Arctic shipping route, shipping costs from China to Europe can be significantly reduced, but this also brings the risk of oil spills along the way, as ordinary oil skimmers cannot be used in icy environments. Summary of the Invention

[0005] To overcome the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a shovel-type oil skimmer, which is designed for crude oil or heavy oil spills on shores, beaches, river surfaces, and icy water surfaces. It can be flexibly arranged and is highly efficient and multifunctional.

[0006] The technical solution of this utility model is: This shovel-type oil collector includes: a bucket 1, an oil collection brush 2, a heatable brush scraper 3, a hydraulic motor 4, a conveying screw 5, an oil pump 6, a bucket heating partition 9, and a connecting assembly 10.

[0007] The bucket is a backhoe bucket, which is equipped with a bucket heating layer and a sludge conveying screw. The sludge conveying screw is driven by a hydraulic motor to transport sludge to the oil pump. The oil collection brush integrates a heated brush scraper. The heated brush scraper cleans the oil collection brush and transfers the sludge to the bucket. This shovel-type oil collector is connected to the excavator arm or the head of a folding boom crane through a connecting component.

[0008] This utility model of a shovel-type oil skimmer uses a bucket, similar in structure to an excavator's backhoe, as its basic component. The active movement of the shovel blades cuts viscous oil sludge into small pieces, which then enter the bucket. This active cutting and scooping capability allows viscous, emulsified, and partially solidified oil sludge to smoothly enter the conveying screw for mixing and transport, preventing it from being unrecoverable due to poor fluidity. The oil skimmer brush serves as a method for recovering crude or heavy oil. The heatable brush scraper can be heated with hot water or steam. Hot water rinsing of the brush achieves the dual purpose of better cleaning the brush and removing the oil sludge, thus ensuring the continuous operation of the shovel-type oil skimmer. Equipped with a hydraulically driven conveying screw, it pushes the scooped-in crude or heavy oil to the oil pump. The spiral motion of the conveying screw further compresses and mixes the crude oil, increasing its homogeneity and fluidity. A bucket heating layer is added inside the bucket. When working on the water surface, especially in extremely cold and icy areas, hot water or steam can be injected through the bucket heating layer to heat and appropriately dilute the heavy oil or crude oil entering the bucket, thereby increasing the fluidity and pumping characteristics of the heavy oil or crude oil.

[0015] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0016] It should be noted that the term "comprising" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0017] like Figure 1-6 As shown, this shovel-type oil collector includes: a bucket 1, an oil collection brush 2, a heated brush scraper 3, a hydraulic motor 4, a conveying screw 5, an oil pump 6, a bucket heating partition 9, and a connecting assembly 10.

[0018] The bucket is a backhoe bucket, which is equipped with a bucket heating layer and a sludge conveying screw. The sludge conveying screw is driven by a hydraulic motor to transport sludge to the oil pump. The oil collection brush integrates a heated brush scraper. The heated brush scraper cleans the oil collection brush and transfers the sludge to the bucket. This shovel-type oil collector is connected to the excavator arm or the head of a folding boom crane through a connecting component.

[0019] This utility model of a shovel-type oil skimmer uses a bucket, similar in structure to an excavator's backhoe, as its basic component. The active movement of the shovel blades cuts viscous oil sludge into small pieces, which then enter the bucket. This active cutting and scooping capability allows viscous, emulsified, and partially solidified oil sludge to smoothly enter the conveying screw for mixing and transport, preventing it from being unrecoverable due to poor fluidity. The oil skimmer brush serves as a method for recovering crude or heavy oil. The heatable brush scraper can be heated with hot water or steam. Hot water rinsing of the brush achieves the dual purpose of better cleaning the brush and removing the oil sludge, thus ensuring the continuous operation of the shovel-type oil skimmer. Equipped with a hydraulically driven conveying screw, it pushes the scooped-in crude or heavy oil to the oil pump. The spiral motion of the conveying screw further compresses and mixes the crude oil, increasing its homogeneity and fluidity. A bucket heating layer is added inside the bucket. When working on the water surface, especially in extremely cold and icy areas, hot water or steam can be injected through the bucket heating layer to heat and appropriately dilute the heavy oil or crude oil entering the bucket, thereby increasing the fluidity and pumping characteristics of the heavy oil or crude oil.

[0020] Preferably, the oil-absorbing brush is a detachable brush.

[0021] Preferably, the shovel-type oil skimmer uses a tracked excavator as a carrier, mounted on an amphibious excavator, or mounted on a small shallow-draft vessel.

[0022] Preferably, the shovel-type oil collector further includes: a first hydraulic universal joint 7 and a second hydraulic universal joint 8. The first hydraulic universal joint rotates 360 degrees to enable the shovel-type oil collector to rotate, and the second hydraulic universal joint swings left and right to enable the shovel-type oil collector to tilt. Equipped with hydraulic universal joints, it can rotate 360 ​​degrees and swing left and right, thus ensuring that the shovel-type oil collector can operate smoothly in confined spaces or at tilted angles, improving its environmental adaptability and ensuring its flexible and versatile layout.

[0023] Preferably, the shovel-type oil collector and the bucket arm form a quick-disassembly working unit.

[0024] The contents of this utility model are described in more detail below.

[0025] like Figure 4 As shown, the shovel-type oil scavenger can be mounted on a deck-mounted folding boom crane or telescopic boom crane. By adjusting the boom's pitch angle and extension / retraction, it can approach the water surface to perform continuous oil scavenging operations. The oil delivery pipelines and hydraulic lines required during the oil scavenging operation can float on the water surface or be suspended from the crane boom.

[0026] like Figure 5 As shown, when operating near mudflats or the shore, tracked excavators can be used as vehicles, or the equipment can be mounted on amphibious excavators or small shallow-draft vessels. When mounted on amphibious vehicles or small shallow-draft vessels, due to storage space limitations, the recovered crude oil / sludge needs to be transferred to the mother ship or shore for storage.

[0027] When operating on beaches and shorelines, the shovel-type oil skimmer utilizes the oleophilic properties of the brush 2 to scrape oil from surface mud, sand, and rocks, then scrapes it into the bucket 1. It can also be used as a basic backhoe bucket to transfer the oil and surface mud to a storage container for oil removal and clarification. The oil-free mud is then returned to the shore. Even better, hot water can be used to wash the ground and brush, helping the brush effectively adhere crude oil from the mud and transfer it to the bucket 1. This method expands the application of the shovel-type oil skimmer from the water surface to the shore, and combined with oil-water and oil-sludge separation technology, allows for a more thorough and effective cleanup of areas contaminated by crude oil.

[0028] When the shovel-type oil skimmer uses a brush to skim oil from the water, the brush adheres the crude oil / sludge to the brush bristles and is scraped into the bucket 1 by the scraper. The conveying screw 5 squeezes and conveys the crude oil / sludge to the oil pump 6 and then to the ship or shore.

[0029] When the shovel-type oil skimmer uses the brush assembly 2 to skim oil on shore, it can use hot water to wash the crude oil on the ground, increase the ground's softness and adhere the crude oil to the brush bristles, and then scrape it into the bucket 1 via the heated brush scraper 3. The conveying screw 5 squeezes and conveys the crude oil / sludge to the oil pump 6 and then to the ship or shore.

[0030] When the shovel-type oil skimmer uses the bucket 1 to skim in oil from the water, it uses the bucket 1 to scoop in relatively viscous, poorly flowing crude oil clumps, and then, under the compression of the conveying screw 5, it is homogenized and transported to the oil pump 6, which then pumps it to the ship or shore.

[0031] When using the shovel-type oil skimmer to skim oil from the shore, the shovel bucket 1 can directly shovel up the oil-containing mud and sand, place it in a temporary storage tank for stirring and sedimentation, and after the mixture has undergone oil skimming / oil removal treatment, the sedimented mud and sand are discharged together with water to restore the ground.

[0032] like Figure 6 As shown, the shovel-type oil collector can be connected to the excavator boom or the head assembly 10 of a folding boom crane, or to the boom rocker arm, integrating them into a single unit. This integrated device becomes a work unit that can be quickly connected and disassembled. The connected unit forms a conveniently connected work unit, allowing for precise operation of the cleaned area. This connection method enables rapid connection and operation. Simultaneously, by utilizing the superior rigidity of the excavator boom, continuous high-intensity oil collection operations can be guaranteed.

[0033] It is particularly important to note that the shovel-type oil skimmer can be used as an oil skimmer in extremely cold icy areas, a function not found in ordinary oil skimmers. In environments with temperatures around -30°C, ice forms on the water / sea surface. The shovel-type oil skimmer can use the gravity of its bucket to break the ice and utilize the bucket's heating layer 9 and brush scraper 3 to heat the shoveled crude oil / sludge with hot water or steam, thus enabling operation in environments where crude oil / sludge is mixed with ice.

[0034] In operating environments with thick crude oil / sludge layers, such as oil sumps in refineries, the bucket 1 can be used as a skimming device to initially separate sludge from water. The sludge entering the bucket can be continuously transferred by the conveying screw 5 and the oil pump 6. Due to the integrated layout of the entire unit, the deployment and retrieval of the equipment become more convenient and faster.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
