Description

Technical Field

[0001] This utility model relates to the technical field of aluminum hydrolysis hydrogen production equipment, and more specifically, to a residue cleaning mechanism for an aluminum hydrolysis hydrogen production reactor. Background Technology

[0002] Against the backdrop of a growing energy crisis and environmental pollution, hydrogen energy, as a clean energy source, has broad application prospects. Hydrogen production via aluminum hydrolysis is an important method, based on the reaction of aluminum with water under certain conditions to generate hydrogen gas. However, the main byproducts in this process are aluminic acid (AlO(OH)) or aluminum hydroxide (Al(OH)3). If these byproduct residues are not cleaned up promptly, they can affect the normal operation of the reactor, reduce hydrogen production efficiency, and may even lead to reactor blockage.

[0003] However, in existing aluminum hydrolysis hydrogen production processes, byproduct residues are cleaned by intermittently stopping the hydrogen production device and removing solid particulate oxides from inside the device, which leads to interruption of hydrogen production and inability to continuously remove solid oxides, making it inconvenient for the hydrogen production device to continue reacting. Based on this, this utility model designs a residue cleaning mechanism for an aluminum hydrolysis hydrogen production reactor to solve the above problems. Utility Model Content

This cleaning mechanism eliminates the need for shutdown for cleaning and achieves continuous removal and collection of residues through the combined action of mechanical scraping and filtration collection, thus extending the reactor's online operating time.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A residue cleaning mechanism for a hydrolysis aluminum hydrogen production reactor includes a reactor with a slag discharge port at the bottom. A slag discharge pipe is fixedly connected to the bottom of the slag discharge port. An electric push rod is installed at the bottom of the slag discharge pipe. The telescopic end of the electric push rod extends into the slag discharge pipe and is fitted with a rubber sealing plug of the same specification as the slag discharge pipe. An inclined guide pipe is connected to the right side of the slag discharge pipe. The right end of the guide pipe is fixedly connected to a residue collection tank. A slag outlet is located at the bottom of the residue collection tank, and a slag discharge pipe is connected to the bottom of the slag outlet. A valve is installed on the slag discharge pipe. The inner wall of the residue collection tank is... A positioning baffle with a conical annular structure is fixedly provided. A filter hopper with a conical structure is set inside the positioning baffle. A mesh cylinder is fixedly connected to the bottom of the filter hopper, and the lower end of the mesh cylinder corresponds to the slag outlet. A circulation pump is installed on the right side of the circumferential surface of the residue collection tank. A discharge pipe is fixedly connected to the bottom right side of the residue collection tank. A second solenoid valve is installed on the discharge pipe. The lower end of the discharge pipe is connected to the input end of the circulation pump through a second conveying hose. A return pipe is fixedly connected to the right side of the circumferential surface of the reactor. A first solenoid valve is installed on the return pipe. The right end of the return pipe is connected to the output end of the circulation pump through a first conveying hose.

[0007] Furthermore, the residue collection tank is provided with a slag inlet at the connection with the guide pipe, and the slag inlet is located on the upper side of the filter screen hopper.

[0008] Furthermore, the upper end of the residue collection tank is sealed with a matching sealing cover by multiple sets of bolts, and a handle is fixed on the upper surface of the sealing cover.

[0009] Furthermore, a positioning ring seat is fixed at the edge of the slag outlet on the bottom of the inner wall of the residue collection tank. The specifications of the positioning ring seat are compatible with the specifications of the mesh cylinder, and the lower end of the mesh cylinder is inserted into the positioning ring seat.

[0010] Furthermore, a drive motor is installed at the upper end of the reactor, and a rotating shaft is vertically arranged inside the reactor. The upper end of the rotating shaft is connected to the output shaft of the drive motor. Several sets of arc-shaped scraper blades are evenly distributed on the annular surface of the rotating shaft near the lower end, and the bottom surface of the scraper blades is in close contact with the bottom wall of the reactor.

[0011] Furthermore, the scraper blade has a right-angled groove near the rotating shaft, and the bottom corner of the right-angled groove is aligned with the edge of the slag discharge port, and the bottom surface of the rotating shaft is flush with the top edge of the right-angled groove.

[0023] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0024] Example:

[0025] like Figures 1 to 6 As shown, a residue cleaning mechanism for a hydrolytic aluminum hydrogen production reactor includes a reactor 2. A slag discharge port 14 is provided at the bottom of the reactor 2. A slag discharge pipe 9 is fixedly connected to the bottom of the slag discharge port 14. An electric push rod 3 is installed at the bottom of the slag discharge pipe 9. The telescopic end of the electric push rod 3 extends into the slag discharge pipe 9 and a rubber sealing plug 17 that is compatible with the specifications of the slag discharge pipe 9 is installed on it. The electric push rod 3 drives the rubber sealing plug 17 to move up and down, thereby opening and closing the slag discharge port 14 to achieve sealing. An inclined guide pipe 10 is connected to the right side of the slag discharge pipe 9 to transport the collected solid residue to the residue collection tank 5. The right end of the guide pipe 10 is fixedly connected to the residue collection tank 5, which is used to collect and store the solid residue. A slag outlet 25 is provided at the bottom of the residue collection tank 5, and a slag discharge pipe 7 is connected to the bottom of the slag outlet 25 to discharge the collected solid residue. A valve 8 is installed on the slag discharge pipe 7. A conical annular positioning baffle 27 is fixedly provided on the inner wall of the residue collection tank 5. A conical filter hopper 23 is provided inside the positioning baffle 27 to collect and filter the solid residue. A mesh cylinder 24 is fixedly connected to the bottom of the filter hopper 23, and the lower end of the mesh cylinder 24 corresponds to the slag outlet 25. A circulation pump 11 is installed on the right side of the annular surface 5. It is used to transport the liquid in the residue collection tank 5 back to the reactor 2 in conjunction with various pipelines. A discharge pipe 22 is fixedly connected to the bottom right side of the residue collection tank 5. A second solenoid valve 21 is installed on the discharge pipe 22. The lower end of the discharge pipe 22 is connected to the input end of the circulation pump 11 through a second delivery hose 6. A return pipe 15 is fixedly connected to the right side of the annular surface of the reactor 2. A first solenoid valve 16 is installed on the return pipe 15. The right end of the return pipe 15 is connected to the output end of the circulation pump 11 through a first delivery hose 4. This design solves the problem that existing aluminum hydrolysis hydrogen production reactors need to intermittently stop the hydrogen production device when cleaning residues, resulting in interruption of hydrogen production and inability to continuously export solid oxides, making it inconvenient for the hydrogen production device to continue the reaction.

[0026] In this embodiment, a slag inlet is provided at the connection between the slag collection tank 5 and the guide pipe 10. The slag inlet is located on the upper side of the filter screen hopper 23. This design allows the slag flowing out of the guide pipe 10 to fall directly into the filter screen hopper 23. Since the guide pipe 10 is usually at a certain angle, the slag has a certain flow velocity and direction under the action of gravity. The position of the slag inlet ensures that the slag can accurately enter the filtration area of ​​the collection tank, avoiding the slag from splashing onto other parts of the collection tank or getting stuck in the edge gaps, thus improving the efficiency of slag collection.

[0027] In this embodiment, a matching sealing cover 20 is installed on the upper end of the residue collection tank 5 by multiple sets of bolts, and a handle 19 is fixed on the upper surface of the sealing cover 20. This design, with the removable sealing cover 20, facilitates the replacement or cleaning of the filter hopper 23 and the screen cylinder 24 inside the residue collection tank 5.

[0028] In this embodiment, a positioning ring seat 26 is fixed at the edge of the slag outlet 25 on the bottom of the inner wall of the residue collection tank 5. The specifications of the positioning ring seat 26 are adapted to the specifications of the mesh cylinder 24, and the lower end of the mesh cylinder 24 is inserted into the positioning ring seat 26. The positioning ring seat 26 provides a precise installation position reference for the mesh cylinder 24. When installing the mesh cylinder 24 into the residue collection tank 5, the operator only needs to align the lower end of the mesh cylinder 24 with the positioning ring seat 26 and insert it to quickly and accurately fix the mesh cylinder 24 above the slag outlet 25. This precise positioning avoids the offset or tilting of the mesh cylinder 24 during the installation process, ensuring the stability and verticality of the mesh cylinder 24 in the tank, enabling the mesh cylinder 24 to perform its function of collecting and storing solid residue normally, while also providing limiting support for the mesh cylinder 24 from the bottom.

[0029] In this embodiment, a drive motor 1 is installed at the upper end of the reactor 2, and a vertically arranged rotating shaft 12 is provided inside the reactor 2. The upper end of the rotating shaft 12 is connected to the output shaft of the drive motor 1. Several sets of arc-shaped scraper blades 13 are evenly distributed on the annular surface of the rotating shaft 12 near the lower end, and the bottom surface of the scraper blades 13 is in close contact with the bottom wall of the reactor 2. This design, through the drive motor 1, the rotating shaft 12, and the scraper blades 13, constitutes a residue cleaning and collection system. Through the design of the rotating shaft 12 and the scraper blades 13, the residue at the bottom of the reactor 2 can be effectively scraped off, and the solid residue can be collected, thereby improving the slag discharge efficiency.

[0030] In this embodiment, a right-angled slot is provided on the scraper blade 13 near the rotating shaft 12, and the bottom corner of the right-angled slot is aligned with the edge of the slag discharge port 14. The bottom surface of the rotating shaft 12 is flush with the top edge of the right-angled slot. This design, through the right-angled slot, can prevent the root of the scraper blade 13 from obstructing the slag discharge port 14, effectively guiding the residue into the slag discharge port 14 and preventing blockage.

[0031] In this embodiment, the diameter of the rubber sealing plug 17 is the same as the inner diameter of the slag discharge pipe 9. When installed in the slag discharge pipe 9, the rubber material itself has a certain elasticity and flexibility, and can undergo slight deformation under pressure, thereby forming a tight fit with the inner wall of the slag discharge pipe 9. This tight fit can effectively prevent the leakage of substances in the slag discharge pipe 9, thereby achieving a seal on the slag discharge port 14. A guide groove 18 is provided on the upper surface of the rubber sealing plug 17. The guide groove 18 is a downwardly concave arc-shaped structure, with the left end of the guide groove 18 being higher than the right end. Its curvature and slope are the same as those of the guide inclined pipe 10. The guide groove 18 can guide the residue falling on the rubber sealing plug 17, allowing it to smoothly enter the guide inclined pipe 10 on the right side along the guide groove 18, preventing the residue from accumulating on the rubber sealing plug 17 and causing blockage.

[0032] The working principle of the residue cleaning mechanism of the aluminum hydrolysis hydrogen production reactor:

[0033] In actual use, the hydrolysis of aluminum to produce hydrogen takes place in reactor 2. Solid residue is generated at the bottom of reactor 2. When a large amount of solid residue needs to be cleaned, all valves 8 are closed, and then the electric push rod 3 is controlled to retract downwards. During the reaction, the upper end of the rubber sealing plug 17 is inserted into the slag discharge port 14, sealing the slag discharge port 14 and the left end of the guide pipe 10. The retraction causes the rubber sealing plug 17 to move downwards until the guide groove 18 on it smoothly transitions to the inner wall of the guide pipe 10, releasing the seal on the slag discharge port 14 and the guide pipe 10. At this time, reactor 2, slag discharge pipe 9, guide pipe 10, and residue collection tank 5 are connected. Some of the residue in reactor 2 falls into the slag discharge pipe 9 through the slag discharge port 14 under gravity, and then enters the residue collection tank 5 through the slag discharge pipe 9. Start the drive motor 1, which drives the rotating shaft 12 to rotate. The rotation of the rotating shaft 12 drives the scraper blades 13 on it to rotate. The rotation of the scraper blades 13 scrapes the bottom wall of the reactor 2, scraping up the residue deposited on the bottom wall. As the scraper blades 13 rotate, the residue gradually gathers along the arc surface of the scraper blades 13 towards the slag discharge port 14 and finally falls into the slag discharge pipe 9 through the slag discharge port 14, thus realizing the collection of residue.

[0034] When solid residue, along with liquid, enters the residue collection tank 5, the solid residue falls into the filter hopper 23, where it is filtered and collected. Then, the electric push rod 3 moves the rubber sealing plug 17 upwards, sealing the slag discharge port 14 and the guide pipe 10. Next, the first solenoid valve 16 and the second solenoid valve 21 are opened, and the circulation pump 11 is started, pumping the liquid from the residue collection tank 5 into the reactor 2. Finally, the valve 8 on the slag discharge pipe 7 is opened, allowing the solid residue in the filter hopper 23 to be discharged through the slag discharge pipe 7, thus completing the cleaning of the solid residue.

[0035] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
