Description

Technical Field

[0001] This utility model relates to the field of formic acid hydrogen production power generation technology, specifically a cleaning mechanism for formic acid hydrogen production high-efficiency power generation equipment. Background Technology

[0002] Formic acid hydrogen production is a promising method. Its principle is based on the chemical properties of formic acid and a specific catalytic reaction. The molecular structure of formic acid contains hydrogen, and under suitable catalytic conditions, formic acid can be decomposed to produce hydrogen and carbon dioxide. The key to this process lies in the catalyst used. A high-quality catalyst can lower the activation energy of the reaction and accelerate the reaction, allowing formic acid to be efficiently decomposed into hydrogen under relatively mild conditions. Currently, many power generation devices on the market utilize formaldehyde to produce hydrogen to generate electricity.

[0003] However, most existing formic acid hydrogen production power generation equipment cannot filter impurities in the formic acid hydrogen production solution. As a result, the impurities in the formic acid hydrogen production solution will reduce the subsequent hydrogen production effect, thus affecting the power generation equipment. Furthermore, after the filter structure has been filtering the impurities in the formic acid hydrogen production solution for a long time, the impurities will usually adhere to the filter structure and cause blockage of its filter pores. As a result, the impurities blocking the filter pores will affect the subsequent filtration performance of the filter structure.

[0004] Therefore, this utility model provides a cleaning mechanism for a high-efficiency formic acid hydrogen production power generation equipment to solve the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a cleaning mechanism for a high-efficiency formic acid hydrogen production power generation equipment, such as... Figure 1-6 As shown, the formic acid hydrogen production high-efficiency power generation equipment includes a power generation equipment body 1. The inner cavity of the power generation equipment body 1 is connected to a feed inlet 2. A filter screen 3 is installed inside the feed inlet 2. A first connecting block 4 is fixedly connected to the outer wall of the filter screen 3. A first spring 5 is fixedly connected to the outer wall of the filter screen 3. The end of the first spring 5 away from the filter screen 3 is fixedly connected to the inner wall of the feed inlet 2. A flow control mechanism is installed inside the feed inlet 2.

[0028] The flow control mechanism includes a first stop 6 rotatably connected inside the feed inlet 2, a motor 7 for driving the first stop 6 to rotate is provided on the outer wall of the feed inlet 2, a second connecting block 8 that contacts the first connecting block 4 is fixedly connected to the outer wall of the first stop 6, and a second stop 9 for controlling the flow rate is provided on the top of the first stop 6.

[0029] Specifically, when flow control of the formic acid hydrogen production solution is required, motor 7 is first started. After motor 7 starts running, its output shaft drives the first stop 6 to rotate, which in turn rotates the first stop 6 and the second stop 9 to compress the flow space in the feed inlet 2. This ensures that the flow of the formic acid hydrogen production solution entering the feed inlet 2 can be controlled according to the opening width formed by the first stop 6 and the second stop 9. This prevents the flow rate of the power generation equipment 1 from being affected by too much or too little formic acid hydrogen production solution, and also prevents the power generation equipment from being overloaded. It also avoids excessive waste in the optimized energy utilization of the power generation equipment 1. At this time, the formic acid hydrogen production solution is poured into the feed inlet 2, so that the formic acid hydrogen production solution can first come into contact with the filter screen 3. The filtration conditions provided by the filter screen 3 can filter out impurities in the formic acid hydrogen production solution, thereby improving the hydrogen production effect of the formic acid hydrogen production solution and ensuring that the power generation equipment 1 is not affected by impurities and its power output is not reduced.

[0030] At the same time, as the motor 7 drives the first stop block 6 to rotate, the first stop block 6 can drive the second connecting block 8 to rotate synchronously. When the second connecting block 8 rotates to contact the first connecting block 4 on the filter screen 3, the two can use the arc-shaped cooperation to make the second connecting block 8 squeeze the first connecting block 4, causing the filter screen 3 to move slightly through the first spring 5.

[0031] After the formic acid hydrogen production solution is transported, the motor 7 can be started to drive the first stop 6 to rotate in the opposite direction. When the first stop 6 and the second stop 9 rotate in opposite directions to a suitable angle, the flow area of ​​the feed inlet 2 can be completely closed. The first stop 6 can also drive the second connecting block 8 to reset. After the second connecting block 8 loses its pressure on the first connecting block 4, the first connecting block 4 can drive the filter screen 3 to reset by the elastic force of the first spring 5. Thus, after the first connecting block 4 on the filter screen 3 is squeezed by the second connecting block 8 and then released, the elastic force of the first spring 5 can achieve a vibration effect, which can clean the impurities clogging the filter holes on the filter screen 3. This reduces the probability that the filter screen 3 will be easily clogged by impurities when filtering formic acid hydrogen production solution for a long time, and manual cleaning is cumbersome and inconvenient. This structure allows the power generation equipment 1 to have both flow control conditions and the conditions for filtering formic acid hydrogen production solution, while ensuring that the filter screen 3 always has the best filtration performance for filtering formic acid hydrogen production solution.

[0032] The first block 6 and the second block 9 are provided with sealing blocks 12 inside, and the outer walls of the first block 6 and the second block 9 are provided with placement grooves 10 for placing the sealing blocks 12.

[0033] A second spring 11 is fixedly connected to the outer wall of the sealing block 12. The end of the second spring 11 away from the sealing block 12 is fixedly connected to the inside of the first stop block 6 and the second stop block 9.

[0034] The first stop block 6 has a through hole 13 inside, and the outer walls of the first connecting block 4 and the second connecting block 8 are arc-shaped.

[0035] Specifically, when the first stop 6 and the second stop 9 rotate, to ensure the accuracy of the formic acid hydrogen production solution flow control, a second spring 11 is installed in the placement groove 10 between the first stop 6 and the second stop 9. This ensures that the second stop 9 remains in contact with the inner wall of the feed inlet 2 through the elastic force of the second spring 11. This prevents the formic acid hydrogen production solution from flowing through the opening of the second stop 9 when the first stop 6 rotates to a certain angle, which would cause inaccurate flow control and result in either too much or too little formic acid hydrogen production solution, affecting the stability of the power generation equipment body 1. Furthermore, the sealing block 12 can adaptively adjust itself through the elastic force of the second spring 11, ensuring that the second stop 9 remains in contact with the feed inlet 2 through the elastic force of the second spring 11. When the inner wall of the inlet 2 is in contact with the material, the sealing block 12 can also seal the opening between the first stop block 6 and the second stop block 9 through the elastic force of the second spring 11. This prevents the flow of formic acid hydrogen production solution from occurring even when the second stop block 9 is in contact with the inner wall of the inlet 2 and the opening is formed between the first stop block 6 and the material. This ensures that the formic acid hydrogen production solution can only flow through the opening created after the first stop block 6 is rotated, further ensuring the accuracy of the flow control of the formic acid hydrogen production solution. The placement groove 10 allows the sealing block 12 to move slightly up and down, preventing the flow of formic acid hydrogen production solution from occurring due to a certain gap at the connection between the sealing block 12 and the second spring 11. The through hole 13 allows a small amount of formic acid hydrogen production solution to flow downwards when it falls on the top of the first stop block 6, ensuring that a small amount of formic acid hydrogen production solution does not always remain on the top of the first stop block 6.

[0036] A switch door 14 is hinged to the bottom of the feed inlet 2, and a cam 15 for pressing the switch door 14 is fixedly connected to the outer wall of the first stop block 6 outside the feed inlet 2.

[0037] A third spring 16 is fixedly connected to the outer wall of the switch door 14, and the end of the third spring 16 away from the switch door 14 is fixedly connected to the outer wall of the feed inlet 2.

[0038] A sealing layer is provided at the gap between the opening / closing door 14 and the feed inlet 2, and a sealing ring is provided at the rotating connection between the feed inlet 2 and the first stop block 6.

[0039] Specifically, after the formic acid hydrogen production solution in the feed inlet 2 has finished flowing, and the impurities filtered by the filter screen 3 adhere to the switch door 14, the motor 7 can be used again to drive the first stop block 6 to rotate. This causes the first stop block 6 to drive the cam 15 to rotate and press against the switch door 14, allowing the switch door 14 to open at an angle using the elastic force of the third spring 16. This allows the impurities on the switch door 14 to be discharged, facilitating cleaning by the staff. After the impurities on the switch door 14 are cleaned, the motor 7 can be used to reverse the direction to reset the first stop block 6. When the cam 15 on the 6 loses pressure on the switch door 14, the switch door 14 can be reset by the elastic force of the third spring 16, so as to continue to seal the feed port 2. The sealing layer between the switch door 14 and the feed port 2 can also effectively prevent some formic acid hydrogen production solution from dripping from the gap of the switch door 14. The sealing ring can also ensure that the rotational connection between the first stop block 6 or the cam 15 and the feed port 2 has a good sealing point, preventing the first stop block 6 and the cam 15 from having a certain gap at the rotational connection with the feed port 2 after long-term rotation, which would cause leakage of formic acid hydrogen production solution, thus ensuring the overall sealing of the feed port 2.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
