Description

Technical Field

[0001] This invention relates to the field of water environment protection, and in particular to an emergency oil spill collection device for rivers. Background Technology

[0002] Oily wastewater pollutes the water environment of rivers. Specialized oil spill collection devices are generally needed to collect the various components of waste oil floating on the water surface in order to protect river water resources and the river's ecological environment.

[0003] Traditional oil spill collection devices cannot separate oil from water in one go when collecting waste oil. They need to collect the oil floating on the river surface along with the wastewater, and then transport the oily wastewater through pipelines to a storage device for centralized water treatment. During this process, because the oily wastewater collected directly has a high oil density, oil easily adheres to the inside of the pipelines transporting the wastewater. With repeated use, the amount of oil adhering to the inner wall of the pipelines increases, easily causing oil blockage. Summary of the Invention

[0004] Therefore, it is necessary to provide an emergency oil spill collection device for rivers that can directly separate oily wastewater from the collected oil.

[0005] This invention provides an emergency oil spill collection device for rivers, comprising: Oil suction roller, used to absorb floating oil on the river surface, includes a central roller body and an oil suction brush; An oil-water treatment assembly is installed downstream of the oil suction roller in the direction of rotation and its horizontal relative position to the oil suction roller is adjustable. It is used to receive the floating oil and oily wastewater adsorbed by the oil suction roller and to perform oil-water separation treatment on the oily wastewater. It includes an oil scraper and a wastewater collection hopper. The oil scraper is rotatably installed inside the sewage collection hopper and has an oil-water separator. The floating oil on the top of the oil scraper, together with the oily sewage, is separated into oil and water by the oil-water separator and then flows into the sewage collection hopper. The sewage collection hopper has a water delivery pipe, and the inner wall contour of the sewage collection hopper connected to the water delivery pipe is arranged to coincide with the movement path of the end of the oil scraper away from the oil suction roller. The water supply pipe is equipped with a filter at one end inside the sewage collection hopper.

[0006] In one embodiment, the oil-water separator includes a pre-separation component, a filter tank, and a side filter strip. The pre-separation component is detachably installed at the opening of the filter tank, which is used to hold adsorbent material. The side filter strip is arranged along the edge of the longer side of the scraper plate and is used to filter oily wastewater passing through the joint between the scraper plate and the wastewater collection hopper.

[0007] In one embodiment, the pre-separation component includes a filter cover, an impeller, and a sponge column. The bottom of the filter cover is provided with a flow guide through the opening of the filter tank. The bottom end of the impeller shaft is rotatably mounted on the top center of the filter cover. The sponge column is sleeved on the hub of the impeller, and the flow guide is covered above the sponge column.

[0008] In one embodiment, the oil scraper has an oil scraping end and a rotating rod. The oil scraping end is located at one end of the oil scraper adjacent to the oil suction brush. The rotating rod is arranged parallel to the axis of the oil suction roller. One end of the rotating rod is mounted on the center line of the oil scraper, and the other end is rotatably mounted on the side wall of the sewage collection hopper.

[0009] In one embodiment, a locking member is fixedly installed at one end of the rotating rod adjacent to the scraper blade, and a locking bolt is threaded onto the locking member. The scraper blade is provided with a locking channel and a screw hole. The tail end of the locking bolt passes through the locking member and is screwed into the screw hole to fix the relative position of the rotating rod and the scraper blade.

[0010] In one embodiment, the oil scraper also has an upper scraper and a lower scraper, the upper scraper and the lower scraper are distributed vertically and are respectively fixedly installed at one end of the oil scraper adjacent to the water supply pipe, and the surfaces of the upper scraper and the lower scraper adjacent to the water supply pipe are in contact with the inner wall of the sewage collection hopper.

[0011] In one embodiment, the lower scraper is arrayed with multiple sets of sewage discharge channels.

[0012] In one embodiment, the scraper blade also has a float mounted on the bottom of one end of the scraper blade adjacent to the lower scraper blade.

[0013] In one embodiment, the outer surface of the sidewall of the sewage collection hopper has a guide rail and a positioning protrusion. The positioning protrusion is located at the end of the guide rail away from the oil suction roller. The surface contours of the guide rail and the positioning protrusion away from the oil suction roller are both arranged in a fan shape.

[0014] In one embodiment, the oil suction roller has a guide block and a positioning element. The guide block is fixedly installed on the side plate surface of the oil suction roller, and the positioning element includes a connecting post and a positioning piece. The connecting post is fixedly installed on the end of the guide block away from the oil suction roller, and the positioning piece is rotatably installed on the connecting post. The positioning piece has a positioning groove that matches the shape of the positioning protrusion. The inner wall of the positioning groove has a limiting protrusion that abuts against the top of the positioning protrusion to maintain the connection between the positioning piece and the positioning protrusion.

[0015] The aforementioned emergency oil spill collection device for the river surface, by adding an oil-water separator to the oil scraper, can simultaneously scrape off floating oil and separate the oil-containing wastewater, thereby reducing the oil content in the wastewater to be pumped out. At the same time, a filter is installed at the inlet of the water pipe to perform secondary filtration of the oil-containing wastewater to be pumped out. The above methods can effectively reduce the oil content of the wastewater entering the water pipe, thereby reducing the occurrence of oil clogging in the water pipe during the transportation of oil-containing wastewater.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0024] Traditional oil spill collection devices include an oil suction roller, an oil scraper, and an oil collection trough. The oil scraper removes oily wastewater from the oil suction roller and pumps it directly to a storage device for centralized water treatment. Because the oil suction roller is mainly used to absorb floating oil on the river surface, the oily wastewater removed has a high oil content. This easily causes oil to adhere to the inner wall of the pipes transporting the oily wastewater. Furthermore, with repeated use, the amount of oil adhering to the inner wall of the pipes increases, easily leading to oil blockage in the transport pipes.

[0025] To solve the above problems, the following will be combined with Figures 1-9 This invention describes an emergency oil spill collection device for rivers.

[0026] like Figure 1 and Figure 2 As shown, in one embodiment, an emergency oil spill collection device for river surfaces includes an oil suction roller 100 and an oil-water treatment component 20.

[0027] The oil suction roller 100 is used to absorb floating oil on the river surface and includes a central roller body 110 and an oil suction brush 120.

[0028] Specifically, the oil suction roller 100 is driven by hydraulic power, which is a conventional technical means in this field, so it will not be described in detail here.

[0029] The oil-water treatment component 20 is installed on the downstream side of the oil suction roller 100 in the direction of rotation. The horizontal relative position of the oil-water treatment component 20 and the oil suction roller 100 is adjustable. It is used to receive the floating oil and oily wastewater adsorbed by the oil suction roller 100 and to perform oil-water separation treatment on the oily wastewater. The oil-water treatment component 20 includes an oil scraper 300 and a wastewater collection hopper 400.

[0030] The oil scraper 300 is rotatably installed inside the sewage collection hopper 400 and has an oil-water separator 310. The floating oil on the top of the oil scraper 300, together with the oily sewage, is separated into oil and water by the oil-water separator 310 and then flows into the sewage collection hopper 400.

[0031] The sewage collection hopper 400 has a water delivery pipe 410 (see...) Figure 5 The inner wall contour of the sewage collection hopper 400 connected to the water supply pipe 410 is set to coincide with the movement path of the oil scraper 300 at the end away from the oil suction roller 100.

[0032] Specifically, by making the end of the oil scraper 300 away from the oil suction brush 120 fit against the inner wall of the sewage collection hopper 400, the flow of oily sewage at the top of the oil scraper 300 is restricted, so that more oily sewage remains on the oil scraper 300.

[0033] It should be noted that the end of the scraper 300 adjacent to the oil suction roller 100 is always higher than the end adjacent to the water supply pipe 410.

[0034] Among them, the water supply pipe 410 is equipped with a filter element 420 at one end inside the sewage collection hopper 400.

[0035] It should be noted that filter element 420 is a sponge block.

[0036] Specifically, in its initial state, the oil scraper 300 near the water pipe 410 is in contact with the inner wall of the sewage collection hopper 400. When using the oil scraper 300 to recover floating oil from the river surface, firstly, rotate the oil scraper 300 to lower the end of the oil scraper 300 near the oil suction roller 100 to a position where it can fit against the oil suction brush 120. Then, move the oil suction roller 100 horizontally toward the oil scraper 300 until the oil suction brush 120 comes into contact with the oil scraper 300. After the operation is completed, use hoisting equipment to lift the oil scraper 300 to the river surface for oil surface cleaning.

[0037] When cleaning up floating oil on the river surface, the oil suction roller 100 drives the oil suction brush 120 to rotate towards the oil scraper 300. The oil scraper 300 and the oil suction brush 120 are in close contact, and a continuous scraping surface is formed by the rotation of the oil suction roller 100, thereby peeling the floating oil adsorbed on the surface of the oil suction brush 120 along with the oily sewage off the oil suction brush 120.

[0038] During this process, the stripped oily wastewater flows along the top of the scraper 300 through the oil-water separator 310 and flows into the oil-water separator 310 for oil-water separation, so that the floating oil is intercepted in the oil-water separator 310. The filtered oily wastewater flows into the wastewater collection hopper 400 and is pumped into the storage equipment by an external suction pump. During the suction process, the floating oil remaining in the oily wastewater is filtered and intercepted again by the filter element 420, so that the oil density in the oily wastewater collected in the storage equipment is extremely low.

[0039] After the floating oil on the river surface is collected, and the oily wastewater on the river surface is fully collected, the emergency oil pollution collection device is lifted back to the oil pollution recovery vessel using hoisting equipment. After the oily wastewater in the sewage collection hopper 400 is fully pumped to the external storage equipment, the oil scraper 300 is rotated to open the opening between the oil scraper 300 and the sewage collection hopper 400 to the maximum extent, so as to facilitate the cleaning of the residual oil on the inner wall of the sewage collection hopper 400.

[0040] like Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, the oil-water separator 310 includes a pre-separation component 312, a filter tank 314, and a side filter strip 316. The pre-separation component 312 is detachably installed at the opening of the filter tank 314, which is used to hold adsorbent material. The side filter strip 316 is arranged along the edge of the longer side of the oil scraper 300 and is used to filter the oily wastewater passing through the joint between the oil scraper 300 and the wastewater collection hopper 400.

[0041] It should be noted that multiple sets of filter channels are provided through the receiving surface of the scraper blade 300, and the filter canister 314 is installed in the filter channels through a sealing ring.

[0042] Optionally, the adsorption material can be fiber ball filter media, activated carbon, diatomaceous earth and other adsorption materials that can adsorb oily substances, and the side filter strip 316 can be a sponge strip.

[0043] In this embodiment, the pre-separation component 312 includes a filter cover 311, an impeller 313, and a sponge column 315. The bottom of the filter cover 311 is provided with a guide port through the opening of the filter tank 314. The bottom end of the shaft of the impeller 313 is rotatably mounted on the top center of the filter cover 311. The sponge column 315 is sleeved on the hub of the impeller 313, and the upper part of the guide port is covered by the sponge column 315.

[0044] Specifically, when oily wastewater flows through the filter cover 311, the flow of oily wastewater impacts the blades on the impeller 313, causing the impeller 313 to rotate. At the same time, the oily wastewater impacts the sponge column 315, which adsorbs some of the floating oil in the oily wastewater. The water filtered by the sponge column 315 flows through the guide port into the filter tank 314 for secondary oil-water separation filtration. During this process, the sponge column 315 is driven to rotate synchronously by the impeller 313, so that the outer surface of the sponge column 315 can be impacted by the flowing oily wastewater, resulting in a uniform distribution of oil on the adsorption surface of the sponge column 315.

[0045] like Figure 6 As shown, in one embodiment, the scraper 300 has a scraping end 320 and a rotating rod 330 (see...). Figure 2 The oil scraping end 320 is located at one end of the oil scraping plate 300 adjacent to the oil suction brush 120. The rotating rod 330 is arranged parallel to the axis of the oil suction roller 100. One end of the rotating rod 330 is installed on the center line of the oil scraping plate 300, and the other end is rotatably installed on the side wall of the sewage collection hopper 400.

[0046] Specifically, a drive handle is fixedly installed at one end of the rotating rod 330 that passes through the sewage collection hopper 400. The staff can adjust the angle by moving the drive handle to drive the scraper plate 300 to rotate.

[0047] In this embodiment, a locking member 332 is fixedly installed at one end of the rotating rod 330 adjacent to the oil scraper 300. A locking bolt 334 is threaded on the locking member 332. The oil scraper 300 is provided with a locking channel 340 and a screw hole. The tail end of the locking bolt 334 passes through the locking member 332 and is screwed into the screw hole to fix the relative position of the rotating rod 330 and the oil scraper 300.

[0048] like Figure 7 As shown, in one embodiment, the oil scraper 300 further includes an upper scraper 350 and a lower scraper 360, which are arranged vertically and are respectively fixedly installed on the oil scraper 300 adjacent to the water pipe 410 (see...). Figure 5 At one end of the upper scraper 350 and the lower scraper 360, the surfaces of the upper scraper 350 and the lower scraper 360 adjacent to the water pipe 410 are both in contact with the inner wall of the sewage collection hopper 400.

[0049] In this embodiment, the lower scraper 360 is provided with multiple sets of sewage discharge channels 362.

[0050] Specifically, the drain channel 362 provides a discharge channel for the oil sludge scraped between the lower scraper 360 and the upper scraper 350. When cleaning the oil sludge in the gap between the upper scraper 350 and the lower scraper 360, the drive handle can be moved back and forth, thereby driving the scraper 300 to rotate back and forth. In this way, the upper scraper 350 and the lower scraper 360 move back and forth in the water, causing the water around the upper scraper 350 and the lower scraper 360 to flow strongly. Thus, the water flow impact force is used to impact and clean the oil sludge in the gap between the upper scraper 350 and the lower scraper 360.

[0051] Specifically, during the process of rotating the oil scraper 300 to a position where it can fit against the oil suction brush 120, the top of the upper scraper 350 scrapes and cleans the oil stains adhering to the inner wall of the sewage collection hopper 400, while the lower scraper 360 scrapes and cleans the inner wall of the sewage collection hopper 400 between the upper scraper 350 and the lower scraper 360.

[0052] When the scraping end 320 of the scraper 300 scrapes and peels off the oily wastewater on the oil suction brush 120 during operation, the upper scraper 350 is in close contact with the inner wall of the wastewater collection hopper 400. The upper scraper 350 intercepts the oily wastewater remaining on the scraper 300 to ensure that the oily wastewater remaining on the scraper 300 is filtered by the oil-water separator 310 before flowing into the wastewater collection hopper 400.

[0053] As the oil scraper 300 is rotated to its highest position near the oil suction brush 120, the bottom end of the lower scraper 360 scrapes and cleans the inner wall of the sewage collection hopper 400. At the same time, the bottom end of the upper scraper 350 scrapes and cleans the inner wall of the sewage collection hopper 400 corresponding to the sewage discharge channel 362. Some of the scraped-off oil and dirt is discharged into the sewage collection hopper 400 through the sewage discharge channel 362.

[0054] In this embodiment, the scraper 300 also has a float 370, which is installed at the bottom of one end of the scraper 300 adjacent to the lower scraper 360.

[0055] It should be noted that the surface of the scraper 300 adjacent to the lower scraper 360 has a fixed bracket, which is used to support the float 370 installed at the bottom of the scraper 300.

[0056] Specifically, when the emergency oil spill collection device is working on the river surface, oily wastewater is always present in the wastewater collection hopper 400. The float 370 is supported by the buoyancy of the water surface, and the end of the oil scraper 300 adjacent to the oil suction brush 120 is kept at the lowest position, that is, the position where it is in close contact with the oil suction brush 120.

[0057] After the oil spill on the river surface is cleaned up, the oily wastewater in the wastewater collection hopper 400 will be fully pumped to the external storage equipment. Since the float 370 obtains buoyancy by immersing itself in the liquid, a certain volume of water needs to be discharged. Therefore, when the amount of water remaining in the wastewater collection hopper 400 is small, the float 370 can assist the water in the wastewater collection hopper 400 to be fully discharged through the water pipe 410.

[0058] like Figure 8 and Figure 9 As shown, in one embodiment, the outer sidewall surface of the sewage collection hopper 400 has a guide rail 430 and a positioning protrusion 440. The positioning protrusion 440 is located at one end of the guide rail 430 away from the oil suction roller 100. The surface contours of the guide rail 430 and the positioning protrusion 440 away from the oil suction roller 100 are both arranged in a fan shape.

[0059] In this embodiment, the oil suction roller 100 has a guide block 130 and a positioning member 140. The guide block 130 is fixedly installed on the side plate surface of the oil suction roller 100. The positioning member 140 includes a connecting post 142 and a positioning piece 144. The connecting post 142 is fixedly installed on one end of the guide block 130 away from the oil suction roller 100, and the positioning piece 144 is rotatably installed on the connecting post 142.

[0060] In this embodiment, the positioning piece 144 has a positioning slot 141, which matches the shape of the positioning protrusion 440. The inner wall of the positioning slot 141 has a limiting protrusion 143, which maintains the connection between the positioning piece 144 and the positioning protrusion 440 by abutting against the top of the positioning protrusion 440.

[0061] Specifically, in the initial state, the oil suction roller 100 is located on the outermost side, that is, the guide block 130 is located at the end of the guide rail 430 away from the positioning protrusion 440. When the oil suction roller 100 is moved toward the sewage collection hopper 400, the guide block 130 moves closer to the positioning protrusion 440 along the guide rail 430. When the oil suction roller 100 moves to a position where it can fit against the oil scraper 300, the guide block 130 is adjacent to the positioning protrusion 440. At this time, it is necessary to fix the relative position of the oil suction roller 100 and the oil scraper 300. Rotate the positioning piece 144 clockwise so that the positioning slot 141 engages with the surface of the positioning protrusion 440. At this time, the limiting protrusion 143 fits against the top of the positioning protrusion 440, so that the positioning piece 144 and the positioning protrusion 440 remain connected. In this way, the relative position of the oil suction roller 100 and the oil scraper 300 is fixed.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
