Description

Technical Field

[0001] This utility model relates to the technical field of aviation kerosene storage, specifically a multi-functional quality inspection system for oil products. Background Technology

[0002] Draining the settling tanks of aviation kerosene storage tanks is a crucial measure to ensure fuel quality and safe tank operation. As an aircraft fuel, aviation kerosene requires extremely high purity; any impurities or moisture can affect its combustion performance and even damage the engine. The settling tank, located at the bottom of the tank, collects impurities (such as sludge and particulate matter) and moisture from the fuel. These impurities and moisture naturally settle to the bottom due to density differences. If not removed promptly, they may contaminate the fuel, leading to quality degradation. Furthermore, moisture and impurities can breed microorganisms, accelerating fuel deterioration and corroding the tank walls and equipment, shortening their service life. Regular drainage effectively removes these harmful substances, prevents sediment buildup, ensures the normal operation of the tanks and related equipment, and meets industry standards and regulations, providing high-quality fuel for air transport. Establishing a comprehensive fuel tank quality inspection system is not only necessary to ensure aviation kerosene quality and safe tank operation but also an important means to meet industry standards, improve resource utilization, and support efficient operation.

[0003] The current aviation kerosene storage tank quality inspection system connects to a drain line at the lowest point of the tank. A gate valve is installed on the drain line to control the draining operation. Two branch lines extend from the main drain line: one connects to a closed-circuit sampler, and the other connects to a quality inspection tank with a conical bottom. Both branch lines are equipped with automatic return valves to precisely regulate the flow direction and velocity of the oil. The closed-circuit sampler is primarily used for visual quality inspection of the oil, facilitating direct observation of impurities and moisture content; the quality inspection tank receives the oil discharged during the inspection process. Recovery lines extending from the bottom of the closed-circuit sampler and quality inspection tank are connected to the main drain line after being controlled by a ball valve. A pneumatic pump is connected to the rear end of the main drain line to pump the oil into a recovery tank, achieving effective resource recovery and utilization. During operation, the gate valve must be fully opened, and the position valves of the quality inspection tank and the closed-circuit sampler must be fully opened at the same time to ensure that the oil passes through the closed-circuit sampler at full flow rate, so as to realize online dynamic extraction of oil samples and thus conduct a comprehensive inspection of oil quality.

[0004] The current aviation kerosene storage tank quality inspection system has the following problems in use: When kerosene is discharged into the quality inspection tank at full flow rate, the high pressure and velocity increase inertial force, causing strong vortices to form on the inner wall of the container. This results in a drop in the center level and a rise in the level on the side levels. To avoid overflow, operators must stop the injection prematurely, reducing container utilization and increasing the risk of spillage. Overflow not only wastes resources but may also cause environmental pollution or safety accidents. Especially in the handling of highly flammable media such as aviation kerosene, overflows may lead to fires or explosions. Utility Model Content

[0005] The purpose of this invention is to provide a multi-functional oil quality inspection system to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional oil quality inspection system, including an inspection tank connected to a sewage pipeline, the inspection tank being provided with a tank cover; the bottom of the inspection tank forming a conical bottom, and the conical bottom being connected to an oil outlet pipe for discharging oil from the inspection tank; an anti-vortex baffle is provided at the position where the conical bottom connects to the oil outlet pipe.

[0007] The multi-functional oil quality inspection system described above includes: the anti-vortex baffle mounting column and multiple baffles fixed equidistantly on the mounting column along the circumference, with a gap formed between two adjacent baffles for oil to enter the oil outlet pipe.

[0008] As described above, in the multi-functional oil quality inspection system: the anti-vortex baffle is fixed to the inner wall of the conical bottom at one end facing the oil outlet pipe.

[0009] The multi-functional oil quality inspection system described above includes an observation port on the side of the inspection tank.

[0010] The multi-functional oil quality inspection system described above includes: an annular cover edge and a semi-annular extended cover edge extending axially along the annular cover edge; a sealing and fixing cover is installed in the area where the annular cover edge and the semi-annular extended cover edge are offset; and a sealing and movable cover is installed on the semi-annular extended cover edge.

[0011] The multi-functional oil quality inspection system described above: the annular cover edge and the semi-annular extended cover edge are integrally formed.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: Oil enters the inspection tank through the drain pipe and is then discharged through the outlet pipe. The anti-vortex baffle prevents the formation of strong vortices on the inner wall of the container when oil is discharged at full flow rate due to increased inertial force caused by high pressure and flow velocity. This avoids the phenomenon of a drop in the center liquid level and a rise in the side liquid level within the inspection tank, fully utilizing the tank's volume and preventing oil overflow due to excessively high edge liquid levels. This improves operational efficiency and reduces resource waste and environmental pollution. Furthermore, the semi-circular extension cover extends a certain distance above the annular cover edge, and the operable sealing cover is installed on the semi-circular extension cover edge, reducing the weight of the cover and making it easier to open. Simultaneously, when the sealing cover is opened, it can prevent rainwater or contaminants accumulated on the lid surface from flowing into the inspection tank, reducing oil contamination and ensuring the purity of the oil and the accuracy of the test results.

Detailed Implementation

[0015] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0016] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0017] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0018] Please see Figures 1-3 In this embodiment of the utility model, the multi-functional oil quality inspection system includes an inspection tank 1 connected to a sewage pipeline, and a tank cover 5 is provided on the inspection tank 1; a conical bottom 2 is formed at the bottom of the inspection tank 1, and an oil outlet pipe 3 for discharging oil from the inspection tank 1 is connected to the conical bottom 2; an anti-vortex baffle 6 is provided at the position where the conical bottom 2 connects to the oil outlet pipe 3.

[0019] In this embodiment, the oil enters the inspection tank 1 through the drain pipe and is then discharged from the inspection tank 1 through the oil outlet pipe 3. The anti-vortex baffle 6 is designed to prevent the formation of strong vortices on the inner wall of the container when the oil is discharged into the inspection tank 1 at full flow rate due to the increased inertial force caused by the high pressure and flow rate. This avoids the phenomenon of the liquid level in the center of the inspection tank 1 dropping while the liquid level on the side wall rises, making full use of the volume of the inspection tank 1 and preventing oil overflow caused by excessively high liquid level at the edge. This improves operating efficiency and reduces resource waste and environmental pollution.

[0020] Specifically, the anti-vortex baffle 6 has a mounting post 602 and multiple baffles 601 fixed equidistantly on the mounting post 602 along the circumference, and a gap is formed between two adjacent baffles 601 to allow the oil to enter the oil outlet pipe 3.

[0021] Preferably, the anti-vortex baffle 6 is fixed to the inner wall of the conical bottom 2 at one end facing the oil outlet pipe 3.

[0022] The baffle 601 is higher than the inner wall of the conical bottom 2. When oil flows into the oil outlet pipe 3, the flow rate and direction of the oil are adjusted by the blocking effect of the baffle 601, thereby effectively reducing the formation of vortices. In addition, the baffle 601 also ensures that the oil can flow into the oil outlet pipe 3 evenly and smoothly, avoiding local accumulation or excessive disturbance of oil in the conical bottom 2.

[0023] It should be noted that the size of the baffle 601 can be adjusted according to requirements, and this embodiment does not impose specific limitations on it.

[0024] Preferably, the side end of the inspection tank 1 is also provided with an observation port 4. The observation port 4 is strip-shaped and transparent, which makes it convenient for staff to observe the oil level in the inspection tank 1.

[0025] Please see Figure 1 The bucket lid 5 includes: an annular cover edge 501 and a semi-annular extended cover edge 503 extending axially along the annular cover edge 501; a sealing and fixing cover 502 is installed in the area where the annular cover edge 501 and the semi-annular extended cover edge 503 are offset; a sealing and movable cover 504 is installed on the semi-annular extended cover edge 503.

[0026] The annular cover edge 501 and the semi-annular extended cover edge 503 are integrally formed.

[0027] In this embodiment, by setting the semi-circular extension cover edge 503 to be a certain distance higher than the annular cover edge 501, and installing the openable sealing movable cover 504 on the semi-circular extension cover edge 503, the weight of the cover body is reduced, making it easier to open the sealing movable cover 504. At the same time, when the sealing movable cover 504 is opened, rainwater or contaminants accumulated on the surface of the barrel cover 5 can be prevented from flowing into the inspection barrel 1 to a certain extent, reducing the contamination of the oil and ensuring the purity of the oil quality and the accuracy of the test results.

[0028] It should be noted that a sealing element is provided on the side of the semi-circular extension cover 503 facing the sealing and fixing cover 502, so that when the bucket lid 5 is opened, only the opening part of the sealing movable cover 504 is in the open state, while the other parts are in the sealed state.

[0029] The sealing movable cover 504 and the semi-circular extension cover edge 503 are connected by a hinge. The sealing movable cover 504 is also equipped with a handle to facilitate manual opening of the sealing movable cover 504 by the staff.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
