Description

Technical Field

[0001] This utility model relates to the field of sewage collection and treatment technology, and more specifically, to a sewage collection device for a dock. Background Technology

[0002] A wharf is a waterfront building or facility in a water and land transportation hub that allows ships to berth, load and unload cargo, and embark and disembark passengers. It usually extends from the shore into the water and can take the form of artificial or natural structures such as breakwaters and staircases. It is the core functional unit of a port.

[0003] In oil tanker shipping, docks, as transit points, are essential infrastructure for oil transportation. However, during the transportation of oil through docks, oil leaks can occur and flow into the shipping channel. When oil combines with water, it forms wastewater that is easily discharged into the waters in front of the dock, polluting the aquatic ecosystem near the dock. This is detrimental to green and sustainable economic development. Therefore, we propose a wastewater collection device for docks to solve the above-mentioned problems. Utility Model Content

[0004] 1. Technical problems to be solved In view of the problems existing in the prior art, the purpose of this utility model is to provide a sewage collection device for docks. It uses purified water for rinsing operations, so it can not only avoid oil pollution of the dock platform to the water body, but also realize the green recycling of sewage.

[0005] 2. Technical Solution

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A sewage collection device for a dock includes a separation tank and a sewage inlet pipe connected in communication with the separation tank. The bottom of the inner cavity of the separation tank is sequentially fixedly connected with a first flow-blocking plate, a first flow-deflecting plate, a second flow-blocking plate, and a second flow-deflecting plate. The separation tank has an oil drain port on its side wall corresponding to the part between the first baffle and the second baffle, and an oil collection tank is provided on the outside of the separation tank corresponding to the oil drain port. The separation tank has a drain outlet on its side wall away from the sewage inlet pipe, and a sewage collection tank is provided on the outside of the separation tank at the location corresponding to the drain outlet. A water pump is installed on the outside of the separation tank, and the output end of the water pump is connected to the sewage inlet pipe through a pipeline. It also includes floating collection components for wastewater collection; The floating collection assembly includes a separation hood, filter holes arranged in an array at the bottom of the separation hood, a float mounted at the root of the outer wall of the separation hood, a sewage suction pipe mounted on the inner side of the separation hood via a bracket, and a flexible hose connected at one end to the sewage suction pipe and at the other end to the input end of the water pump.

[0008] Furthermore, a filter tank is fixedly connected to the inner side of the separation tank at the location corresponding to the sewage inlet pipe.

[0009] Furthermore, multiple pontoons are provided, and the multiple pontoons surround the separation cover.

[0010] Furthermore, the bottom end of the sewage pipe extends to a position close to the filter hole.

[0011] Furthermore, the separation cover is made of aluminum alloy.

[0012] Furthermore, the diameter of the filter hole is larger than the diameter of the through hole on the filter tank.

[0013] Furthermore, the oil drain outlet is located below the sewage inlet pipe and above the drain outlet.

[0014] 3. Beneficial Effects Compared with existing technologies, the advantages of this utility model are: (1) In this scheme, the buoyancy of the pontoon is used to make the separation cover float on the upper layer of the oil sludge, and the solid waste in the waterway is isolated through the filter holes. The oil floating on the upper layer of the water is extracted through the sewage pipe when the water pump is started, and then enters the separation tank through the hose and sewage inlet pipe. Utilizing the principle that oil is lighter and water is heavier, the water is pushed upward from the gap between the first baffle and the first deflector, while the oil is blocked in the separation tank through the second baffle and the second deflector. When the oil layer reaches the oil outlet, it is discharged into the oil collection tank, while the water enters the sewage collection tank through the drain outlet. The purified water can be used for flushing operations. Therefore, it can not only avoid the pollution of water bodies by oil sludge on the dock platform, but also realize the green recycling of sewage.

[0015] (2) In this scheme, by setting up a filter tank, fine impurities in the water can be effectively filtered out, and impurities can be prevented from settling in the separation tank, so as to ensure the effect of oil-water treatment. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Example: Please see Figure 1-5 A sewage collection device for a dock includes a separation tank 1 and a sewage inlet pipe 2 connected in a conductive manner to the separation tank 1. The bottom of the inner cavity of the separation tank 1 is sequentially fixedly connected to a first flow-blocking plate 3, a first flow-deflecting plate 4, a second flow-blocking plate 5, and a second flow-deflecting plate 6. An oil drain port 7 is provided on the side wall of the separation tank 1 at the part between the first baffle plate 4 and the second baffle plate 5, and an oil collection tank 8 is provided on the outside of the separation tank 1 at the part corresponding to the oil drain port 7. A drain outlet 9 is provided on the side wall of the separation tank 1 away from the sewage inlet pipe 2, and a sewage collection tank 10 is provided on the outside of the separation tank 1 at the location corresponding to the drain outlet 9. A water pump 12 is installed on the outside of the separation tank 1, and the output end of the water pump 12 is connected to the sewage inlet pipe 2 through a pipe. It also includes floating collection components for wastewater collection; The floating collection assembly includes a separation hood 13, filter holes 14 arranged in an array at the bottom of the separation hood 13, a float 15 installed at the root of the outer wall of the separation hood 13, a sewage pipe 16 installed inside the separation hood 13 by a bracket, and a hose 17 connected at one end to the sewage pipe 16 and at the other end to the input end of the water pump 12. It should be noted that when using this sewage collection device for the dock, the floating collection component is first deployed to the area of ​​the dock channel polluted by oil. The buoyancy of the float 15 causes the separation cover 13 to float on the upper layer of oil, and the solid waste in the channel is isolated through the filter hole 14. The oil floating on the upper layer of water is extracted through the sewage pipe 16 when the water pump 12 is started, and then enters the separation tank 1 through the hose 17 and the sewage inlet pipe 2. Utilizing the principle that oil is lighter and water is heavier, the water is pushed upward from the gap between the first baffle plate 3 and the first baffle plate 4, while the oil is blocked in the separation tank 1 through the second baffle plate 5 and the second baffle plate 6. When the oil layer reaches the oil outlet 7, it is discharged into the oil collection tank 8, while the water enters the sewage collection tank 10 through the drain outlet 9. The purified water can be used for flushing operations. Therefore, it can not only avoid the pollution of water bodies by oil on the dock platform, but also realize the green recycling of sewage.

[0020] like Figure 1 As shown, a filter tank 11 is fixedly connected to the inner side of the separation tank 1 at the location corresponding to the sewage inlet pipe 2, and the diameter of the filter hole 14 is larger than the diameter of the through hole on the filter tank 11. It should be noted that by setting up the filter tank 11, fine impurities in the water can be effectively filtered out, preventing impurities from settling in the separation tank 1, so as to ensure the effect of oil-water treatment.

[0021] like Figure 1 As shown, multiple floats 15 are provided, and multiple floats 15 surround the separation cover 13. The separation cover 13 is made of aluminum alloy. It should be noted that while ensuring the buoyancy of the separation cover 13, it is also possible to ensure the balance of the separation cover 13 during the floating process.

[0022] like Figure 5 As shown, the bottom end of the sewage pipe 16 extends to a position close to the filter hole 14; It should be noted that the sewage pipe 16 is beneficial for extracting oil floating on the surface of the water.

[0023] like Figure 1 , Figure 3 As shown, the oil drain outlet 7 is located below the sewage inlet pipe 2 and above the drain outlet 9. It should be noted that, utilizing the principle that oil is lighter and water is heavier, water is pushed upward through the gap between the first baffle plate 3 and the first baffle plate 4, while grease is blocked in the separation tank 1 by the second baffle plate 5 and the second baffle plate 6. When the oil layer reaches the oil discharge port 7, it is discharged into the oil collection tank 8, while the water enters the sewage collection tank 10 through the drain port 9.

[0024] In use: First, the floating collection assembly is deployed to the area of ​​the dock channel polluted by oil. The buoyancy of the float 15 makes the separation cover 13 float on the upper layer of oil. The solid waste in the channel is isolated through the filter hole 14. The oil floating on the upper layer of water is extracted through the sewage pipe 16 when the water pump 12 is started. Then, it enters the separation tank 1 through the hose 17 and the sewage inlet pipe 2. Utilizing the principle that oil is lighter and water is heavier, the water is pushed upward from the gap between the first baffle plate 3 and the first baffle plate 4, while the oil is blocked in the separation tank 1 through the second baffle plate 5 and the second baffle plate 6. When the oil layer reaches the oil outlet 7, it is discharged into the oil collection tank 8, while the water enters the sewage collection tank 10 through the drain outlet 9.

[0025] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
