Description

Technical Field

[0001] The invention relates to the technical field of oil skimmers, and in particular to an icy zone high-viscosity oil spill skimmer with a multi-stage heating function. Background Art

[0002] An oil skimmer is any mechanical device designed to recover spilled oil or oil-water mixtures from water without altering their physical or chemical properties. The skimmer's basic operating principle is to separate oil from the water surface by utilizing the flow characteristics of oil and oil-water mixtures, the density difference between oil and water, and the adsorption capacity of materials to oil / water mixtures.

[0003] Oil skimmers are generally designed based on the fluidity of oil at room temperature. However, the low temperatures in ice regions significantly affect oil viscosity, causing crude oil or heavy fuel oil to solidify or form a semi-solid colloid. Furthermore, the heterogeneous "oil-in-ice" or "ice-in-oil" structures formed by the mixing of floating ice and spilled oil can block the inlet or transmission pipelines of mechanical recovery devices, causing frequent equipment jams or even damage. Existing technical solutions to improve oil fluidity through local heating still have the following problems:

[0004] 1. Insufficient single-stage heating efficiency: A single heat source cannot evenly cover a large oil spill area, causing local oil temperature to rise while other areas remain highly viscous, resulting in limited improvement in overall recovery rate.

[0005] 2. Incomplete ice treatment: It is difficult to penetrate the thick ice layer to release the trapped oil spill by only surface heating, and the free water produced by melting ice may dilute the oil-water mixture, increasing the difficulty of subsequent separation. Summary of the Invention

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The following first describes the concepts involved in this application with reference to the accompanying drawings. It should be noted that the following description of each concept is intended only to make the content of this application easier to understand and does not limit the scope of protection of this application. At the same time, the embodiments and features in the embodiments of this application can be combined with each other unless there is a conflict. The following detailed description of this application will be made with reference to the accompanying drawings and in conjunction with the embodiments.

[0030] like Figures 1 to 6 As shown, the present invention provides an ice area high-viscosity oil spill recovery machine with a multi-stage heating function, comprising a machine body 1, a cutting device 2 is provided at the inlet of the machine body 1, and the cutting device 2 strikes the ice-oil mixture when cutting the ice-oil mixture, an oil collection brush belt 3 and an oil collecting pool 4 with a heating function are provided in the machine body 1, and the cut ice-oil mixture is transported to the oil collecting pool 4 via the oil collection brush belt 3, a recovery pump 5 capable of steam heating is provided in the oil collecting pool 4, a heating system is provided on the oil collection brush belt 3, a monitoring and control system is further provided in the machine body 1, and the monitoring and control system adjusts the temperature of the oil collecting pool 4, the recovery pump 5 and the heating system by monitoring the sea ice content information in the ice-oil mixture at the oil collection brush belt 3, the oil collecting pool 4 and the recovery pump 5.

[0031] The cutting device 2 includes a frame 201 arranged on the body 1, and a cutting structure 202, a striking structure 203 and a hot air blowing structure 204 are arranged on the frame 201. The cutting structure 202 and the striking structure 203 have the same rotation direction, and the rotation center lines of the cutting structure 202 and the striking structure 203 are parallel to each other. The hot air blowing structure 204 blows hot air on the cutting structure 202 and the striking structure 203.

[0032] When the present application is in use, the oil recovery machine is located in the oil spill area in the ice zone, and then the cutting device 2, the recovery pump 5, the oil recovery brush belt 3 and the heating system are turned on. The cutting device 2 cuts and crushes the ice-oil mixture, and then the oil recovery brush belt 3 transports the chopped ice-oil mixture to the oil collecting pool 4, and finally the oil in the oil collecting pool 4 is extracted and recovered by the recovery pump 5. During the whole process, the heating system continuously heats the oil recovery brush belt 3, so that the sea ice in the ice-oil mixture is melted into seawater during transportation on the oil recovery brush belt 3, and the seawater flows out along the gaps on the oil recovery brush belt 3. The oil collecting pool 4 also heats the ice-oil mixture inside it to further melt the sea ice. The recovery pump 5 turns on the steam heating function, which can further increase the temperature of the ice-oil mixture during transportation and reduce the viscosity of the spilled oil, thereby reducing the pressure and the probability of blockage of the recovery pump 5, and improving the recovery rate of high-viscosity oil spills in the ice zone. In addition, the present application further improves the oil spill recovery rate through multi-stage heating.

[0033] During the process of the cutting device 2 cutting the ice-oil mixture, the cutting structure 202 and the striking structure 203 rotate in the same direction. Therefore, at the spatial position between the cutting structure 202 and the striking structure 203, the rotation directions of the cutting structure 202 and the striking structure 203 are opposite. One of the cutting structure 202 and the striking structure 203 rotates upward, and the other rotates downward. In this application, the striking structure 203 is located between the cutting structure 202 and the body 1. Since the cutting structure 202 and the striking structure 203 rotate in the same direction, in the space between the rotation center lines of the cutting structure 202 and the striking structure 203, if the cutting structure 202 rotates upward, the striking structure 203 rotates downward, that is, the cutting direction and the striking direction of the cutting device 2 are opposite, so that the ice-oil mixture cut by the cutting structure 202 will be struck by the striking structure 203. Moreover, since the cutting direction and the striking direction are opposite, not only the crushing effect of the ice-oil mixture is improved, but also the large pieces of ice-oil mixture adhering to the cutting structure 202 can be accelerated to separate from the cutting structure 202. In this embodiment, the rotation directions of the cutting structure 202 and the striking structure 203 are both along the same direction. Figure 2 The clockwise direction shown in the figure, that is, the direction of the linear velocity when cutting at the lowest point on the cutting structure 202, points to the oil-collecting brush belt 3, so that the cut and crushed ice-oil mixture can flow toward the oil-collecting brush belt 3 through the stirring of the cutting structure 202 and the striking structure 203, so as to help the oil-collecting brush belt 3 to transport the ice-oil mixture. In addition, the cutting and crushing of the ice-oil mixture by the cutting device 2 can effectively release the spilled oil inside the ice-oil mixture, so that the spilled oil can be separated from the ice layer.

[0034] During the process of cutting and transporting the ice-oil mixture, the monitoring and control system is always turned on. By capturing image information at the oil-collecting brush belt 3 and the oil-collecting pool 4, the sea ice content in the oil-collecting brush belt 3 and the oil-collecting pool 4 is monitored, and then the temperature of the oil-collecting pool 4 and the heating system are controlled and adjusted to reduce the sea ice content, thereby reducing the water content of the spilled oil pumped by the recovery pump 5 and improving the oil spill recovery efficiency.

[0035] In this embodiment, the oil collection brush belt 3, the oil collecting pool 4, the recovery pump 5 and the monitoring and control system are all existing technologies. For example, the oil collecting pool 4 with a heating function can be a container with an electric heating wire or a heating coil, and the recovery pump 5 has a steam heating function, etc. The above technical principles will not be elaborated on here.

[0036] The cutting structure 202 includes a cutting shaft 205 rotatably connected to the frame 201 . A plurality of cutting blades 206 are evenly spaced on the cutting shaft 205 , and the thickness of each cutting blade 206 gradually increases along the outer circumference toward the center of the cutting shaft 205 .

[0037] When cutting, the cutting structure 202 drives the cutting device 2 to rotate through a driving device such as a motor, thereby driving the multiple cutting blades 206 to rotate synchronously to cut the ice-oil mixture. Since the cutting blades 206 gradually become thicker in the radial direction, the ice-oil mixture is gradually expanded, thereby improving the cutting effect of the ice-oil mixture.

[0038] A plurality of auxiliary cutting blades 207 are disposed on both sides of the cutting blade 206 , and the plurality of auxiliary cutting blades 207 on the same side of the cutting blade 206 are evenly distributed around the rotation center of the cutting blade 206 .

[0039] When the cutting blade 206 cuts the ice-oil mixture, multiple auxiliary cutting blades 207 will cut into the ice-oil mixture in sequence as the ice-oil mixture gets closer and closer to the center of the cutting blade 206, and the cutting direction of the auxiliary cutting blades 207 is perpendicular to the cutting plane of the cutting blade 206. The auxiliary cutting blades 207 cut the ice-oil mixture on the flat side wall of the ice-oil mixture where the cutting blade 206 cuts, further cutting the ice-oil mixture, improving the cutting effect of the ice-oil mixture, and making the subsequent heating and melting of the sea ice more effective.

[0040] The side of the auxiliary cutting piece 207 facing the center of the cutting blade 206 is an inwardly concave arc surface, and the side of the auxiliary cutting piece 207 away from the center of the cutting blade 206 is a plane perpendicular to the radial direction of the cutting blade 206, and the plane side and the arc surface side on the auxiliary cutting piece 207 are connected to form a cutting edge.

[0041] The auxiliary cutting blade 207 has a flat surface on one side and an arcuate surface on the other side, so that the auxiliary cutting blade 207 gradually surfaces from the cutting edge, so that the auxiliary cutting blade 207 can expand and break the ice-oil mixture when cutting the ice-oil mixture, further improving the cutting effect of the ice-oil mixture.

[0042] The striking structure 203 includes a connecting shaft 208 rotatably set on the frame 201, and a plurality of striking balls 209 are arranged on the connecting shaft 208 at equal intervals along the axial direction, and each striking ball 209 is connected to the connecting shaft 208 through an elastic rod 210. Each striking ball 209 passes between two adjacent cutting blades 206 when moving.

[0043] The connecting shaft 208 is driven by a driving device such as a motor to drive the multiple elastic rods 210 to rotate, thereby driving the multiple knocking balls 209 to rotate synchronously, so that the multiple knocking balls 209 knock on the ice-oil mixture, causing the ice-oil mixture to be further broken up, thereby preventing large pieces of ice-oil mixture from adhering to the cutting blade 206 and affecting the cutting efficiency of the cutting blade 206.

[0044] The hot air blowing structure 204 includes a plurality of air nozzles 211 uniformly arranged on the frame 201 along the axial direction of the cutting axis 205 , and the plurality of air nozzles 211 are connected to an air pump via an air pipe.

[0045] Hot air is blown between the cutting shaft 205 and the connecting shaft 208 through the air nozzle 211 to further prevent oil spillage from adhering to the striking structure 203 and the cutting structure 202 .

[0046] The heating system includes a heating cover 6 arranged in the machine body 1 and located above the oil-collecting brush belt 3 . The heating cover 6 is provided with a hot air outlet 7 , and the hot air outlet 7 is used to convey hot air into the heating cover 6 .

[0047] Hot air is delivered to the heating cover 6 through the hot air outlet 7, which can increase the air temperature on the surface of the oil collecting brush belt 3, thereby accelerating the melting of the ice-oil mixture delivered on the oil collecting brush belt 3 to reduce the sea ice content in the ice-oil mixture.

Any person skilled in the art may make slight changes or modifications to other equivalent embodiments without departing from the scope of the technical means disclosed in the content of the present invention, but they should still be regarded as technologies or embodiments that are essentially the same as the present invention.
