For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0036] See Figures 1 to 6 , this embodiment provides an automatic feed adjustment system for raw materials based on the change in hydrogen production flow rate, which is applied to the raw material supply of a hydrogen production device. The hydrogen production device includes a reaction tank 1, and a first pipeline 2 for discharging hydrogen is provided on the reaction tank 1. A first flow meter is provided on the first pipeline 2. The automatic feed adjustment system for raw materials includes: a frame; a first storage tank, arranged on the frame, including a first tank body 4 and a second tank body 5; the second tank body 5 is arranged inside the first tank body 4 and is used for storing solid raw materials; both ends of the second tank body 5 are slidably connected to the first tank body 4 in the vertical direction; a first discharge port 6 is provided at the bottom of the second tank body 5, and a first control valve 7 is provided at the first discharge port 6; the reaction tank 1 is located below the storage tank, and the first discharge port 6 is communicated with the reaction tank 1; a remaining amount detection mechanism, arranged inside the first tank body 4; the detection end of the remaining amount detection mechanism is connected to the second tank body 5 and is used for detecting the remaining amount of solid raw materials in the second tank body 5; a second storage tank 8, arranged on the frame and used for storing liquid raw materials; the second storage tank 8 is communicated with the reaction tank 1 through a conveying assembly and is used for conveying the liquid raw materials to the reaction tank 1; the remaining amount detection mechanism, the first control valve 7, and the conveying assembly are all in communication connection with the first flow meter.

[0037] In this embodiment, solid raw materials, such as aluminum or magnesium, are arranged in the first storage tank, and liquid raw materials, such as sodium hydroxide solution, are correspondingly stored in the second storage tank 8. By setting a first flowmeter on the first pipeline 2 of the reaction tank 1, the hydrogen flow rate generated after the reaction is monitored in real time and fed back to the remaining amount detection mechanism, the first control valve 7 and the conveying assembly. Through program setting, the fixed raw materials and liquid raw materials can be conveyed to the reaction tank 1 for reaction according to requirements. For example, when it is necessary to increase the hydrogen flow rate, the opening degree or the discharging time of the first discharging port 6 is controlled by the first control valve 7 to increase the amount of solid raw materials conveyed to the reaction tank 1, and at the same time, the conveying device is controlled to increase the amount of liquid raw materials conveyed to the reaction tank 1, thereby increasing the hydrogen flow rate generated by the reaction; when it is necessary to decrease the hydrogen flow rate, the opposite operation to the above can be performed; in addition, the remaining amount of solid raw materials is detected in real time by the remaining amount detection mechanism, so as to obtain the discharging amount of the solid raw materials conveyed by the first discharging port 6, and then the corresponding proportion of liquid raw materials can be output in cooperation with the conveying assembly, improving the matching accuracy, enabling the solid raw materials and liquid raw materials to react fully, avoiding waste caused by inappropriate proportions, and reducing costs.

[0038] Preferably, as Figure 3 shown, a support portion 9 is provided in the first tank body 4. The support portion 9 penetrates vertically to the bottom and is provided with a second discharging port 10. The second discharging port 10 is communicated with the top of the reaction tank 1 through a second pipeline 3; the two ends of the second tank body 5 are respectively provided with a first matching portion 11 and a second matching portion 12, and the first discharging port 6 is arranged on the first matching portion 11; the first matching portion 11 is slidably inserted into the second discharging port 10, and the second matching portion 12 is slidably matched with the top of the first tank body 4.

[0039] It should be noted that both the first matching portion 11 and the second matching portion 12 are arranged vertically.

[0040] In this embodiment, the second tank body 5 is matched with the first tank body 4 through the first matching portion 11 and the second matching portion 12, ensuring that the second tank body 5 has movement in the vertical direction, improving stability, and cooperating with the remaining amount detection mechanism to detect the remaining amount of the raw materials in the second tank body 5 by using the gravity of the sinking of the second tank body 5.

[0041] Preferably, as Figure 3 shown, the remaining amount detection mechanism includes a plurality of weighing sensors 13, and the plurality of weighing sensors 13 are arranged on the support portion 9; a support ring 14 is provided on the peripheral side of the second tank body 5; the plurality of weighing sensors 13 are evenly arranged around the axis of the support ring 14 and correspond to the position of the support ring 14; the weighing sensors 13 are in contact with the support ring 14.

[0042] It should be noted that the detection end of the weighing sensor 13 is in contact with the support ring 14.

[0043] In this embodiment, a plurality of weighing sensors 13 are arranged around the circumference of the second tank body 5 and abut against the support ring 14 on the second tank body 5 through the weighing sensors 13 to detect the weight of the second tank body 5 in real time, so as to monitor the discharge amount and the remaining amount and improve the detection accuracy.

[0044] Preferably, as Figure 3 and Figure 6 shown, a limiting groove 15 is provided at the bottom of the support ring 14, a limiting block 16 is provided on the support part 9 corresponding to the limiting groove 15, the top end of the limiting block 16 is slidably inserted into the limiting groove 15 in the vertical direction, and the top of the limiting block 16 is preset with a distance from the bottom of the limiting groove 15.

[0045] In this embodiment, through the cooperation of the limiting block 16 and the limiting groove 15, the circumferential direction of the second tank body 5 is limited to prevent the second tank body 5 from rotating during operation. Moreover, the preset distance between the top of the limiting block 16 and the bottom of the limiting groove 15 affects the detection effect and improves the stability. At the same time, this preset distance can be set according to the actual situation, specifically according to the maximum detection weight of the weighing sensor 13. During the weighing process, since the weighing sensor 13 abuts against the second tank body 5, the second tank body 5 will move slightly in the vertical direction as the weight changes. The distance that the second tank body 5 moves downward beyond the limit value of the weighing sensor 13 is set as the limit distance, and the preset distance can be set to be less than or equal to the limit distance to protect the weighing sensor 13.

[0046] Preferably, as Figure 3 shown, the raw material automatic feeding adjustment system based on the change of the hydrogen production flow rate further includes a first stirring assembly. The first stirring assembly includes a first driving member 17, a first rotating shaft 18 and a plurality of paddle blades 19; the first rotating shaft 18 is rotatably arranged in the second tank body 5 and is driven to rotate by the first driving member 17; the plurality of paddle blades 19 are arranged at intervals along the axial direction of the first rotating shaft 18, and a plurality of protrusions 20 are provided on the surface of the paddle blades 19.

[0047] In this embodiment, the first driving member 17 drives the first rotating shaft 18 to drive the paddle blades 19 to rotate to stir the solid raw materials. Through the mutual friction between the protrusions 20 on the surface of the paddle blades 19 and the solid raw materials, the oxide layer on the surface of the solid raw materials falls off, improving the reaction effect between the fixed raw materials and the liquid raw materials.

[0048] Specifically, as Figure 3 shown, the first driving member 17 is communicatively connected with the first flowmeter. A screw rod 29 is coaxially provided at the bottom of the first rotating shaft 18, and the screw rod 29 is adaptively extended into the first discharge port 6. The first driving member 17 is communicated with the first flowmeter, and the rotation speed of the screw rod 29 driven by the first driving member 17 is controlled according to the demand, thereby realizing the adjustment of the feeding speed of the solid raw materials and improving the adjustment accuracy.

[0049] Specifically, the blades 19 are in a plate-like structure or a spiral structure that is arranged obliquely.

[0050] Preferably, at least one of the first rotating shaft 18 and the paddle 19 is embedded with a heating element.

[0051] In this embodiment, a heating element is provided in the blade 19 or the first rotating shaft 18. The heating element may be a heating rod or a heating wire to increase the activity of the solid raw material so as to increase the reaction rate with the liquid raw material.

[0052] Preferentially, if Figure 4 As shown, the reaction tank 1 is provided with a first reaction chamber, and the first reaction chamber is cylindrical; a second rotating shaft 21 is provided in the first reaction chamber to rotate along its axis, and a second driving member 22 for driving the second rotating shaft 21 to rotate is provided on the reaction tank 1; a plurality of partition plates 23 are provided on the second rotating shaft 21 around its axial direction, and the partition plates 23 are preset at a distance from the top of the first reaction chamber; the plurality of partition plates 23 divide the first reaction chamber into a plurality of second reaction chambers; the first discharge port 6 and the connection points between the second storage tank 8 and the reaction tank 1 both correspond to the same second reaction chamber.

[0053] In this embodiment, a plurality of partition plates 23 are arranged on the second rotating shaft 21 to divide the first reaction chamber into a plurality of second reaction chambers. When feeding, the second rotating shaft 21 can be driven by the second driving member 22 to drive the partition plates 23 to rotate, and a certain proportion of solid raw materials and liquid raw materials are transported into each second reaction chamber in turn and divided into multiple groups for reaction, which can increase the contact area between the solid raw materials and the liquid raw materials, so that the solid raw materials and the liquid raw materials can fully react, improve the reaction efficiency, avoid waste, and the multiple groups of solid raw materials and liquid raw materials react continuously to maintain the continuous generation of hydrogen.

[0054] Preferentially, if Figure 1 , Figure 2 and Figure 6 As shown, the automatic feed adjustment system for raw materials based on the change in the output hydrogen flow rate also includes a discharge component; a discharge port 24 is provided at the bottom of the reaction tank 1, and the discharge component is connected to the discharge component; the position of the discharge port 24 corresponds to the position of one of the second reaction chambers; the position of the discharge port 24 is staggered with the position of the second reaction chamber corresponding to the second storage tank 8.

[0055] In this embodiment, the discharge assembly is connected through the discharge port 24 at the bottom of the reaction tank 1, so that when the second driving member 22 drives the second reaction chamber to rotate, it also pushes the corresponding residues remaining after the fixed raw material and liquid raw material react to move. When the residue moves to a position corresponding to the discharge port 24, the residue can be discharged so that the fixed raw material and liquid raw material can be input again for reaction. The position of the discharge port 24 is staggered with the position of the second reaction chamber corresponding to the second storage tank 8 to avoid the fixed raw material and liquid raw material from not having time to react and being discharged.

[0056] Specifically, Figure 1 As shown, the discharge port 24 is connected to the second storage tank 8 to two adjacent second reaction chambers respectively. During operation, the second driving member 22 drives the second reaction chamber connected to the second storage tank 8 to rotate in a direction away from the discharge port 24. Each time it rotates, the position of the next adjacent second reaction chamber is connected to the second storage tank 8, and then the raw material is input again, thereby gradually inputting the raw material into each second reaction chamber, and the second reaction chamber into which the raw material has been input moves toward the discharge port 24 while reacting to generate hydrogen, until it rotates to correspond to the discharge port 24 and discharges the reaction residue through the discharge port 24.

[0057] Specifically, both the first driving member and the second driving member are servo motors.

[0058] Specifically, Figure 1 and Figure 2 As shown, the discharge assembly includes a fourth pipeline and a third control valve. The fourth pipeline is connected to the discharge port 24. The third control valve is arranged on the fourth pipeline for controlling opening and closing.

[0059] Preferably, if Figure 4 and Figure 7 As shown, the automatic feed adjustment system for raw materials based on the change of the output hydrogen flow rate also includes a second stirring component, and the second stirring component is provided in at least one second reaction chamber; the second stirring component includes a fixed block 30, a gear 31, an adjustment block 32, a swing rod 33 and a stirring rod 34; a rack 35 is provided around the side wall of the first reaction chamber, and the rack 35 is preset at a distance from the bottom of the first reaction chamber; the fixed block 30 is fixedly connected to the partition plate; the gear 31 is rotatably set on the fixed block 30 and meshes with the rack 35; the adjustment block 32 is rotatably set on the fixed block 30; one end of the swing rod 33 is rotatably connected to the tooth surface of the gear 31 deviating from its axial position, and the other end is horizontally slid through the fixed block 30 and is suspended; one end of the stirring rod 34 is connected to the suspended end of the swing rod 33, and the other end extends into the second reaction chamber and is provided with a stirring paddle.

[0060] It should be noted that the axis of the gear 31 is parallel to the axis of the fixing block 30 .

[0061] In this embodiment, a second stirring assembly is arranged in the second reaction chamber to facilitate stirring of the mixture in the second reaction chamber and improve the reaction efficiency. When the second driving member 22 drives the second rotating shaft 21 to rotate, the partition plate 23 drives the second stirring assembly to rotate together. The gear 31 located on the fixed block 30 cooperates with the rack 35, thereby driving the gear 31 to rotate. The gear 31 drives the swing rod 33 to perform an eccentric motion. Under the limiting action of the adjusting block 32, the swing of the swing rod 33 is realized, and then the stirring rod 34 and the stirring paddle are driven to swing, realizing stirring. The driving force of the second driving member 22 is fully utilized to drive the gear 31 to rotate, realizing overall linkage and ingenious cooperation, achieving the stirring effect, improving the structural compactness, and improving the space utilization rate. The rack 35 is preset at a certain distance from the bottom of the first reaction chamber, reserving enough space to avoid affecting the placement of raw materials. It can be understood that the number of the second stirring assemblies can be set according to requirements, and the second stirring assemblies can be arranged in multiple or all of the second reaction chambers.

[0062] Specifically, a groove for installing the rack 35 is provided on the side wall of the first reaction chamber, and the rack 35 is arranged in the groove to facilitate cooperation with the gear 31 and avoid affecting the rotation of the partition plate 23.

[0063] Preferably, as Figure 1 shown, the conveying assembly includes an infusion pump 25, a second flowmeter, and a second control valve 26. The second storage tank 8 is communicated with the reaction tank 1 through a third pipeline 27. The infusion pump 25, the second flowmeter, and the second control valve 26 are arranged on the flow path of the third pipeline 27.

[0064] In this embodiment, the liquid raw material is conveyed to the reaction tank 1 through the infusion pump 25, the second flowmeter, and the second control valve 26, and the output flow is monitored in real time by the second flowmeter to facilitate precise control of the proportion of the liquid raw material.

[0065] Preferably, a liquid level observation window 28 is provided on the second storage tank 8.

[0066] In this embodiment, the liquid level condition in the second storage tank 8 is observed in real time through the liquid level observation window 28 to facilitate timely replenishment.

[0067] Working principle of the present invention: The flow rate of hydrogen is detected in real time and can be set through a program. According to the change in the flow rate, the feeding amounts and ratios of the solid raw material and the liquid raw material are adjusted through the first control valve 7, the infusion pump 25, the weighing sensor 13, and the second control valve 26, thereby increasing the flow rate of the hydrogen generated by the reaction, achieving dynamic adjustment, improving the matching accuracy, enabling the solid raw material and the liquid raw material to fully react, avoiding waste caused by inappropriate ratios, reducing costs, and at the same time driving the paddle 19 to rotate through the first driving member 17 to eliminate the oxide layer on the surface of the solid raw material, and driving the partition plate 23 to rotate through the second driving member 22, enabling the raw materials to be input into each second reaction chamber for reaction, and discharging the reaction residues after the reaction through the discharge port 24.
