Description

Technical Field

[0001] This utility model relates to the field of fuel additive flowability testing technology, specifically to an environmentally friendly fuel additive flowability testing device. Background Technology

[0002] With the continuous advancement of energy conservation and emission reduction policies, environmentally friendly fuel additives are increasingly widely used in diesel, gasoline, and bioethanol fuels. Fuel additives can improve combustion performance, reduce emissions, enhance oxidation resistance and lubricity. Their flowability (i.e., flow characteristics under different temperature and viscosity conditions) directly affects fuel mixing uniformity and injection stability, and is an important indicator for evaluating their application performance. To ensure the stability of products during low-temperature storage, transportation, and use, it is usually necessary to test and evaluate the flowability of fuel additives during the production process.

[0003] Existing detection devices mostly use fixed channels or single flow hole structures, which cannot effectively simulate the actual flow state of fuel additives in pipes with different roughness, thus making it difficult to reflect their resistance characteristics and adhesion behavior in real transportation systems. Utility Model Content

[0004] The purpose of this invention is to provide an environmentally friendly fuel additive flowability testing device, which solves the problem that existing testing devices mostly use fixed channels or single flow hole structures, which cannot effectively simulate the actual flow state of fuel additives in pipes with different roughness, and thus cannot truly reflect their resistance characteristics, adhesion characteristics and dispersion performance in the conveying system.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An environmentally friendly fuel additive flowability testing device includes:

[0007] Testing station;

[0008] The detection assembly includes a detection frame, a detection shaft, a first drive component, and several detection tubes;

[0009] The test equipment is mounted on the test platform;

[0010] The detection shaft is horizontally arranged and rotatably mounted on the detection frame;

[0011] A plurality of the detection tubes are evenly distributed along the axial direction of the detection shaft and fixedly connected to the periphery of the detection shaft, and the inner walls of the plurality of detection tubes have different roughness.

[0012] The first driving member is used to drive the detection shaft to rotate, so as to adjust the position of the detection tube;

[0013] An adjustment component, located on the testing platform, is used to drive the testing frame to swing vertically, thereby adjusting the tilt angle of the testing frame.

[0014] A further technical solution is that the detection frame is provided with a feeding assembly; the feeding assembly includes a feeding frame, a feeding pipe, and a feeding cylinder; the feeding frame is fixed on the detection frame; the feeding pipe is disposed on the feeding frame and parallel to the detection pipe; the feeding cylinder is vertically connected and fixed to the end of the feeding pipe away from the detection pipe; wherein, the detection shaft is rotated by the first driving component so that any of the detection pipes is coaxially connected with the feeding pipe; the end of the feeding pipe away from the detection pipe is sealed.

[0015] A further technical solution is that a discharge pipe coaxial with the feed pipe is fixed on the detection frame; when the detection pipe and the feed pipe are aligned, the discharge pipe is coaxially connected to the end of the detection pipe away from the feed pipe.

[0016] A further technical solution is that connecting rings are provided at both ends of the detection tube, and at the opposite ends of the feeding tube and the discharge tube; when the detection tube and the feeding tube are aligned, adjacent connecting rings are magnetically connected.

[0017] A further technical solution is that the feeding rack has an arc-shaped limiting surface; an adsorption groove is opened on the arc-shaped limiting surface; an adsorption block with a sliding direction parallel to the feeding tube is provided in the adsorption groove by means of a tension spring; the feeding tube is fixed on the adsorption block and slidably disposed on the arc-shaped limiting surface; when the detection tube and the feeding tube are aligned, the feeding tube is adsorbed and connected to the detection tube through the connecting ring.

[0018] A further technical solution is that the testing station is equipped with a collection box for receiving the additives after they pass through the discharge pipe.

[0019] A further technical solution is that the adjustment assembly includes an adjustment shaft, an adjustment block, and a second driving member; the adjustment block is disposed on the detection table; both sides of the detection frame are rotatably disposed on the adjustment block via the adjustment shaft; the second driving member is used to drive the adjustment shaft to rotate.

[0020] A further technical solution is that the testing platform is provided with a support for supporting the testing frame; the height of the support is the same as the height of the adjusting block.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] By setting multiple detection tubes with different inner wall roughness in the same detection device and using a servo motor to drive the detection shaft to rotate, the detection tubes can be switched quickly, allowing the fuel additive to flow through pipe structures with different roughness, thereby simulating its flow state in various actual conveying systems.

[0023] Compared to existing detection methods with fixed channels or single flow hole structures, this solution can complete flowability tests under various working conditions under the same experimental conditions, significantly improving the flexibility of detection and the representativeness of results.

[0024] Meanwhile, the test frame can be tilted at different angles by adjusting the components, allowing the fluid to flow under different slope conditions. This more realistically reflects the flow characteristics of fuel additives under the combined action of gravity and viscous resistance in the actual pipeline network, thereby enabling comprehensive detection and analysis of their resistance coefficient, adhesion characteristics, and dispersion performance.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] Example:

[0032] like Figures 1-3As shown, this utility model provides an environmentally friendly fuel additive flowability testing device, including a testing platform 1, a testing component 2, and an adjustment component 3. The testing component 2 includes a testing frame 21, a testing shaft 22, a first driving member 23, and several testing tubes 24. The testing frame 21 is mounted on the testing platform and includes a base and two vertically arranged seats. The testing shaft 22 is horizontally arranged and rotatably mounted on the two vertical seats. Several testing tubes 24 are evenly distributed along the axial direction of the testing shaft 22 and are fixedly connected to the periphery of the testing shaft 22 by fixing rods 25, and the inner walls of the several testing tubes 24 have different roughnesses. The first driving member 23 is used to drive the testing shaft 22 to rotate, so as to adjust the position of the testing tubes 24. The adjustment component 3 is mounted on the testing platform and is used to drive the testing frame 21 to swing vertically, so as to adjust the tilt angle of the testing frame 21. The first driving member 23 is a servo motor, the power end of which rotates through the vertical seat and is coaxially fixed to one end of the testing shaft 22.

[0033] The principles and beneficial effects of the above technical solution:

[0034] By setting multiple detection tubes 24 with different inner wall roughness in the same detection device and using a servo motor to drive the detection shaft 22 to rotate, the rapid switching between detection tubes 24 can be achieved, allowing the fuel additive to flow through pipe structures with different roughness, thereby simulating its flow state in various actual conveying systems.

[0035] Compared to existing detection methods with fixed channels or single flow hole structures, this solution can complete flowability tests under various working conditions under the same experimental conditions, significantly improving the flexibility of detection and the representativeness of results.

[0036] Meanwhile, the tilt angle of the test frame 21 can be adjusted by the adjustment component 3, so that the fluid flows under different slope conditions, which more realistically reflects the flow characteristics of the fuel additive under the combined action of gravity and viscous resistance in the actual delivery pipeline, thereby realizing the comprehensive detection and analysis of its resistance coefficient, adhesion characteristics and dispersion performance.

[0037] In this embodiment, the testing frame 21 is provided with a feeding assembly 4; the feeding assembly 4 includes a feeding frame 41, a feeding pipe 42, and a feeding cylinder 43; the feeding frame 41 is fixed on the testing frame 21; the feeding pipe 42 is disposed on the feeding frame 41 and parallel to the testing pipe 24; the feeding cylinder 43 is vertically connected and fixed to the end of the feeding pipe 42 away from the testing pipe 24; wherein, the first driving member 23 drives the testing shaft 22 to rotate so that any testing pipe 24 is coaxially connected to the feeding pipe 42; the upper end of the feeding cylinder 43 has a feeding port; a cover 44 is threadedly connected to the feeding port; the end of the feeding pipe 42 away from the testing pipe 24 is sealed.

[0038] The principles and beneficial effects of the above technical solution:

[0039] The feeding component 4 is fixed together with the detection frame 21 and can rotate and tilt synchronously with the detection frame 21 to avoid feeding errors. The additive can be fed into the feeding cylinder 43 through the feeding port. After the additive is added, the cover can be closed to prevent external impurities or air bubbles from entering, ensuring detection accuracy and data stability. The end of the feeding tube 42 away from the detection tube 24 is blocked to avoid additive waste.

[0040] In this embodiment, a discharge pipe 5 coaxial with the feed pipe 42 is fixed on the detection frame 21; when the detection pipe 24 and the feed pipe 42 are aligned, the discharge pipe 5 is coaxially connected with the end of the detection pipe 24 away from the feed pipe 42.

[0041] The principles and beneficial effects of the above technical solution:

[0042] By fixing the discharge pipe 5, which is coaxial with the feed pipe 42, on the test frame 21, the discharge pipe 5 can be automatically connected when the test pipe 24 is aligned with the feed pipe 42, ensuring that the fuel additive can flow continuously through the test channel.

[0043] In this embodiment, both ends of the detection tube 24 and the opposite ends of the feeding tube 42 and the discharge tube 5 are provided with connecting rings 6; the connecting rings 6 are magnetic rings; when the detection tube 24 and the feeding tube 42 are aligned, adjacent connecting rings 6 are magnetically connected.

[0044] The principles and beneficial effects of the above technical solution:

[0045] Connecting rings 6 are provided at the ends of the detection tube 24, the feed tube 42 and the discharge tube 5, and magnetic adsorption connections are formed between adjacent connecting rings 6. This ensures the sealing of the fluid connection and allows for quick disassembly and assembly, making it convenient to clean and replace detection tubes 24 with different roughnesses.

[0046] In this embodiment, the feeding rack 41 has an arc-shaped limiting surface 411; an adsorption groove 412 is opened on the arc-shaped limiting surface 411; an adsorption block 414 with a sliding direction parallel to the feeding tube 42 is provided in the adsorption groove 412 through a tension spring 413; the feeding tube 42 is fixed on the adsorption block 414 and slidably disposed on the arc-shaped limiting surface 411; when the detection tube 24 and the feeding tube 42 are aligned, the feeding tube 42 is adsorbed and connected to the detection tube 24 through the connecting ring 6.

[0047] The principles and beneficial effects of the above technical solution:

[0048] When the detection tube 24 is aligned with the feeding tube 42, the feeding tube 42 automatically attaches to the detection tube 24, achieving precise alignment and sealing. When the feeding tube 42 and the detection tube 24 are disconnected, the feeding tube 42 can return to its initial position under the action of the tension spring 413, preventing the feeding tube 42 from being in place before it is connected to the detection tube 24, thus avoiding friction between the ends of the two tubes.

[0049] In this embodiment, the testing station is equipped with a collection box 7 for receiving the additives after passing through the discharge pipe 5.

[0050] The principles and beneficial effects of the above technical solution:

[0051] The testing platform is equipped with a collection box 7, which is used to receive the fuel additive after passing through the discharge pipe 5, so as to realize the centralized collection of the test sample liquid and subsequent testing.

[0052] In this embodiment, the adjustment component 3 includes an adjustment shaft, an adjustment block 31, and a second drive component 32. The adjustment block 31 is disposed on the testing platform. The two sides of the testing frame 21 are respectively rotatably disposed on the adjustment block 31 via the adjustment shaft. The second drive component 32 is used to drive the adjustment shaft to rotate. The second drive component 32 is a servo motor, whose power end rotates through the adjustment block 31 and is coaxially fixed with one of the adjustment shafts.

[0053] The principles and beneficial effects of the above technical solution:

[0054] By setting up an adjusting shaft, adjusting block 31, and second drive component 32, the tilt angle of the detection frame 21 can be precisely controlled. The second drive component 32 is driven by a servo motor, enabling the detection frame 21 to be adjusted within a wide range to simulate the flow behavior under different conveying slope conditions.

[0055] In this embodiment, the testing platform is provided with a support 8 for supporting the testing frame 21; the height of the support 8 is the same as the height of the adjusting block 31.

[0056] The principles and beneficial effects of the above technical solution:

[0057] A support 8 of the same height as the adjustment block 31 is set on the testing platform, which can provide stable support when not in operation and prevent the device from shaking or tilting and becoming unbalanced.
