It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the utility model provides a technical solution: a high-efficiency plate and shell heat exchanger for hydrogen production, comprising a shell 1, and an anti-short circuit component 2 is movably installed inside the shell 1;

[0025] The anti-short circuit component 2 includes a center plate 21, a first Y-shaped filling plate 22 and a second Y-shaped filling plate 23. The first Y-shaped filling plate 22 and the second Y-shaped filling plate 23 are respectively arranged on both sides of the center plate 21. Both ends of the first Y-shaped filling plate 22 and the second Y-shaped filling plate 23 are rotatably connected to the limit plates 28. The two limit plates 28 are located at both ends of the shell 1. The anti-short circuit component 2 is arranged inside the shell 1 to control the flow direction of the internal medium while ensuring the structural strength of the entire shell 1. The two limit plates 28 are respectively arranged at both ends of the shell 1, and the center plate 21 is arranged at the center of the shell 1 to ensure that the pressure resistance of the shell 1 will not decrease. When in use, during the process of the medium flowing from the bottom to the top, the medium located on both sides of the shell 1 will contact the first Y-shaped filling plate 22 and the second Y-shaped filling plate 23, and the flow direction changes from the original two sides of the shell 1 to flowing toward the center of the shell 1. The first Y-shaped filling plate 22 and the second Y-shaped filling plate 23 are made of 0.8mm stainless steel strips, and the stainless steel metal material has good temperature resistance.

[0026] according to Figure 2 , Figure 3 and Figure 4 As shown, a connecting plate 24 is fixedly connected between the first Y-shaped filling pressure plate 22 and the second Y-shaped filling pressure plate 23. The connecting plate 24 is located on one side of the limiting plate 28. The connecting plate 24 connects the first Y-shaped filling pressure plate 22 and the second Y-shaped filling pressure plate 23 to improve the overall structural stability.

[0027] according to Figure 2 and Figure 4As shown, one end of the connecting plate 24 is fixedly connected to a positioning rod 25, and the other end of the positioning rod 25 is fixedly connected to an extension rod 26. The positioning rod 25 is located at the center of the connecting plate 24, and the extension rod 26 at its end is used by operators.

[0028] according to Figure 2 As shown, a sealing ring 27 is fixedly installed on the outer wall of the extension rod 26, and the extension rod 26 passes through the shell 1. When in use, the extension rod 26 can be pulled to drive the connecting plate 24, so as to pull the first Y-shaped filling pressure plate 22 and the second Y-shaped filling pressure plate 23 a certain distance away from the limit plate 28, so as to facilitate position adjustment.

[0029] according to Figure 4 As shown, a tension spring 210 is fixedly connected to one side of the connecting plate 24, and the other end of the tension spring 210 is fixedly connected to the inner wall of the shell 1. The tension spring 210 is sleeved on the outer wall of the positioning rod 25. Under normal conditions, the tension spring 210 will push the connecting plate 24 against the limit plate 28 through the positioning rod 25. When compressed, sufficient space can be freed up for the connecting plate 24 to move.

[0030] according to Figure 4 and Figure 5 As shown, both ends of the first Y-shaped filling pressure plate 22 and the second Y-shaped filling pressure plate 23 are fixedly installed with a bonding plate 211, and one side of the bonding plate 211 is fixedly installed with an anti-slip slide 212. The first Y-shaped filling pressure plate 22 and the second Y-shaped filling pressure plate 23 are connected to the limiting plate 28 through the anti-slip slide 212 on the bonding plate 211 to ensure the stability of the first Y-shaped filling pressure plate 22 and the second Y-shaped filling pressure plate 23. The anti-slip slide 212 is L-shaped, which can prevent the first Y-shaped filling pressure plate 22 and the second Y-shaped filling pressure plate 23 from falling off from the limiting plate 28.

[0031] according to Figure 2 and Figure 3 As shown, a limiting groove 29 is provided on one side of the limiting plate 28, and the shape of the limiting groove 29 is adapted to the shape of the anti-slip slide 212. The thickness of the limiting groove 29 is greater than the thickness of the anti-slip slide 212, ensuring that the first Y-shaped filling plate 22 and the second Y-shaped filling plate 23 can rotate after the anti-slip slide 212 moves a certain distance.

[0032] The use method and working principle of the device: two limit plates 28 are respectively arranged at the two ends of the shell 1, and the center plate 21 is arranged at the center of the shell 1. When in use, the medium flows from the bottom to the top. During the flow of the medium, it will contact the first Y-shaped filling plate 22 and the second Y-shaped filling plate 23. The first Y-shaped filling plate 22 and the second Y-shaped filling plate 23 are made of 0.8mm stainless steel strips. Under the guidance of the first Y-shaped filling plate 22 and the second Y-shaped filling plate 23, the medium will flow to the center of the shell 1, so as to avoid the problem of liquid short circuit;

[0033] If it is necessary to change the position of the first Y-shaped filling pressure plate 22 and the second Y-shaped filling pressure plate 23, the extension rod 26 can be pulled to compress the tension spring 210, so that the anti-slip slide 212 moves a certain distance in the limiting slide groove 29. At this time, the bonding plate 211 is separated from the limiting plate 28. It is only necessary to rotate the extension rod 26 to change the position of the first Y-shaped filling pressure plate 22 and the second Y-shaped filling pressure plate 23. After determining the position, release the extension rod 26. Under the rebound of the tension spring 210, the bonding plate 211 is pushed back onto the limiting plate 28 to ensure that there is sufficient friction to maintain the stability of the first Y-shaped filling pressure plate 22 and the second Y-shaped filling pressure plate 23.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
