[0037] Figure 1The drying device 10 of a nuclear power plant steam generator in some embodiments of the present utility model is shown. The drying device 10 of the nuclear power plant steam generator is used to introduce hot air into nuclear power facilities when needed, so as to dry corresponding equipment, devices, mechanisms or areas, etc. For example, it can be used to dry the evaporator. Of course, it can also be used to dry the remaining devices or components, etc.

[0038] As Figure 1 shown, the drying device 10 of the nuclear power plant steam generator includes two connecting devices 1, a blowing device 2, a heating device 3 and a wind guiding device 4. The blowing device 2 is connected to the heating device 3 through one of the connecting devices 1, and the heating device 3 is connected to the wind guiding device 4 through the other connecting device 1.

[0039] It can be understood that each connecting device 1 includes two parts, which are respectively arranged on the other two parts or devices that need to be tightly connected; the detachable connection between the two parts or devices can be realized through these two parts of the connecting device 1. In this way, the detachable connection between the blowing device 2 and the heating device 3 can be realized, and the detachable connection between the heating device 3 and the wind guiding device 4 can also be realized.

[0040] It should be noted that the wind guiding device 4 is fixedly arranged on the evaporator. When drying is required, the heating device 3 is correspondingly connected to the wind guiding device 4, and the hot air generated by the common operation of the blowing device 2 and the heating device 3 can be conveyed to the evaporator.

[0041] As Figures 2 to 5 shown, each connecting device 1 includes a first connecting component 11 and a second connecting component 12. The first connecting component 11 includes a plurality of first connecting bars 111 and a plurality of first connecting U-clips 112, and the second connecting component 12 includes a plurality of second connecting bars 121 and a plurality of second connecting U-clips 122.

[0042] The blowing device 2 includes a housing 21 and a blowing component 22. An air outlet 211 is formed on the housing 21. The blowing component 22 is arranged on the housing 21, and the blowing component 22 is used to blow out the air flow from the air outlet 211. The first connecting component 11 is arranged on the air outlet 211.

[0043] It can be understood that the outer contour, size specification and structural composition of the housing 21 can be flexibly set, and it plays a role in supporting and installing. The blowing component 22 is used to suck the gas into the housing 21 during operation and make the gas blow out from the air outlet 211.

[0044] The heating device 3 includes a heating cylinder 31 and a heating component 32. The heating component 32 is arranged inside the heating cylinder 31. A second connection component 12 is provided at the air inlet end 311 of the heating cylinder 31, and a first connection component 11 is provided at the air outlet end 312 of the heating cylinder 31.

[0045] Understandably, the heating cylinder 31 is generally cylindrical in shape. The gas flows along the length extension direction of the heating cylinder 31. During the flowing process, the air flow will come into contact with the heating component 32, thereby achieving the function of the gas. The air inlet end 311 is used for the gas to enter the heating cylinder 31, and the air outlet end 312 is used for the gas inside the heating cylinder 31 to be discharged.

[0046] The air guiding device 4 includes an air guiding pipe 41. A first connection component 11 is provided at the inlet end 411 of the air guiding pipe 41, and the outlet end 412 of the air guiding pipe 41 is communicated with the evaporator.

[0047] Understandably, the air guiding pipe 41 is generally tubular in shape. The inlet end 411 of the air guiding pipe 41 is used to receive the gas heated by the heating device 3. The heated gas flows along the air guiding pipe 41, and the heated gas is discharged through the outlet end 412. At this time, the outlet end 412 has been pre-connected to the equipment required for drying (such as an evaporator). The heated gas is correspondingly supplied to the equipment, device, mechanism or area that needs to be dried.

[0048] Such as Figure 3 and Figure 4 as shown Figure 3 In the figure, the connecting device is in an un-locked and mated state. Figure 4 In the figure, the connecting device is in a locked state. The heating cylinder 31 rotates so that the first connection component 11 and the second connection component 12 rotate relative to each other. Thus, each first connection bar 111 is inserted and clamped into each second connection U-shaped clip 122 one by one, and each second connection bar 121 is inserted and clamped into each first connection U-shaped clip 112 one by one. Furthermore, the air inlet end 311 and the air outlet 211 are tightly mated and communicated, and the air outlet end 312 and the inlet end 411 are tightly mated and communicated.

[0049] Understandably, the size specification of the first connection bar 111 is configured to be adapted to the size specification of the second connection U-shaped clip 122; the size specification of the first connection U-shaped clip 112 is configured to be adapted to the size specification of the second connection bar 121.

[0050] During the connection process using the connecting device 1, after the first connecting strip 111 is correspondingly inserted into the second connecting U-shaped card 122, the second connecting U-shaped card 122 and the second connecting strip 121 will clamp the first connecting strip 111 from two opposite directions respectively. That is, the first connecting strip 111 will be tightly abutted against the first connecting strip 111 under the propping of the second connecting U-shaped card 122. Similarly, after the second connecting strip 121 is correspondingly inserted into the first connecting U-shaped card 112, the second connecting strip 121 will also be tightly abutted against the first connecting strip 111 under the propping of the first connecting U-shaped card 112. In this way, the first connecting strip 111 and the second connecting strip 121 will drive the two components where they are respectively located to approach and abut against each other. For example, the air inlet end 311 and the air outlet 211 are tightly fitted and abutted; or the air outlet end 312 and the introduction end 411 are tightly fitted and abutted, effectively ensuring the connection tightness at the connection position.

[0051] In addition, if it is necessary to disassemble the connecting device 1, by relatively rotating the first connecting component 11 and the second connecting component 12, so that each first connecting strip 111 is correspondingly disengaged from each second connecting U-shaped card 122, and each second connecting strip 121 is correspondingly disengaged from each first connecting U-shaped card 112, the disassembly of the first connecting component 11 and the second connecting component 12 can be completed, thereby separating the heating device 3 from the blowing device 2, and the heating device 3 can also be separated from the air guiding device 4.

[0052] In summary, the blowing device 2, the heating device 3 and the air guiding device 4 are all detachably connected to each other, and the corresponding connection can be completed by rotation, improving the operation convenience. And both the blowing device 2 and the heating device 3 can be used separately after disassembly, enabling the device to be correspondingly adapted to different scenarios, improving the universality.

[0053] It should be noted that the rotation of the aforementioned heating cylinder 31 includes the active rotation of the heating cylinder 31 while the blowing device 2 is in a fixed state, and also includes the heating cylinder 31 being in a fixed state while the blowing device 2 rotates, and also includes the separate rotation of the blowing device 2 and the heating device 3. All of these can complete the activities or rotation methods required for the connection or disassembly of the connecting device 1. Similarly, the rotation of any one of the heating cylinder 31 and the air guiding device 4 or the separate rotation of both can achieve the connection of the connecting device 1.

[0054] Both the first connecting U-shaped card 112 and the second connecting U-shaped card 122 are configured as U-shaped structures with openings facing one side, and the opening sizes match the widths of the first connecting strip 111 and the second connecting strip 121.

[0055] Such as Figures 2 to 5As shown, in some embodiments of the drying device 10 for the steam generator of a nuclear power plant, each first connecting U-shaped clamp 112 is correspondingly arranged on each first connecting bar 111, and each second connecting U-shaped clamp 122 is correspondingly arranged on each second connecting bar 121.

[0056] It can be understood that each first connecting U-shaped clamp 112 is correspondingly arranged on each first connecting bar 111, and each second connecting U-shaped clamp 122 is correspondingly arranged on each second connecting bar 121. This means that there is a first connecting U-shaped clamp 112 on each first connecting bar 111, and similarly, there is a second connecting U-shaped clamp 122 on each second connecting bar 121.

[0057] In this way, when assembling the first connecting component 11 and the second connecting component 12, the first connecting U-shaped clamp 112 can limit the position of the second connecting U-shaped clamp 122 on the first connecting bar 111, preventing the second connecting U-shaped clamp 122 from directly slipping out of the end of the first connecting bar 111 when sliding along the first connecting bar 111.

[0058] As Figure 3 As shown, in some embodiments of the drying device 10 for the steam generator of a nuclear power plant, the width of the first connecting bar 111 gradually decreases along the length extension direction to form a first wide end 1111 and a first narrow end 1112, and each first connecting U-shaped clamp 112 is arranged on each first wide end 1111;

[0059] The width of the second connecting bar 121 gradually decreases along the length extension direction to form a second wide end 1211 and a second narrow end 1212, and each second connecting U-shaped clamp 122 is arranged on each second wide end 1211;

[0060] Among them, when the heating cylinder 31 rotates, each first connecting bar 111 is inserted into the second connecting U-shaped clamp 122 through the first narrow end 1112, and each second connecting bar 121 is inserted into the first connecting U-shaped clamp 112 through the second narrow end 1212.

[0061] It can be understood that the width of the first narrow end 1112 is smaller, which is convenient for inserting into the second connecting U-shaped clamp 122, thus ensuring the smoothness of the connection. The width of the second narrow end 1212 is smaller, which is convenient for inserting into the first connecting U-shaped clamp 112, also ensuring the smoothness of the connection.

[0062] After the first narrow end 1112 is completely inserted into the second connecting U-shaped clamp 122, as the heating cylinder 31 continues to rotate, the first wide end 1111 will gradually approach the second connecting U-shaped clamp 122 and finally be closely fitted with the second connecting U-shaped clamp 122. Similarly, after the second narrow end 1212 is completely inserted into the first connecting U-shaped clamp 112, as the heating cylinder 31 continues to rotate, the second wide end 1211 will gradually approach the first connecting U-shaped clamp 112 and finally be closely fitted with the first connecting U-shaped clamp 112.

[0063] Due to the relatively large widths of the first wide end 1111 and the second wide end 1211, after they are fully inserted into the corresponding U-shaped cards, they can form a tighter engagement with the U-shaped cards, ensuring the stability and tightness of the connection. Of course, the second connecting U-shaped card 122 and the first connecting U-shaped card 112 will prevent the U-shaped cards from reaching the wide ends completely, but compared with the narrow ends, the positions closer to the wide ends can still form a tighter fit with the corresponding U-shaped cards.

[0064] As Figure 3 shown, in some embodiments of the drying device 10 for nuclear power plant steam generators, a guiding surface 1113 is provided at the end of the first narrow end 1112, and a guiding surface 1213 is provided at the second narrow end 1212.

[0065] It can be understood that a guiding surface 1113 is provided at the first narrow end 1112, and this surface helps the first narrow end 1112 to be aligned and inserted into the second connecting U-shaped card 122 more smoothly. A guiding surface 1213 is provided at the second narrow end 1212, and this guiding surface 1213 helps the second narrow end 1212 to be aligned and inserted into the first connecting U-shaped card 112 more smoothly.

[0066] In this way, through this type of embodiment, it can be ensured that each component can be accurately aligned during the connection process, thus ensuring the smoothness and reliability of the entire connecting device 1 during connection and cooperation.

[0067] As Figures 3 to 5 shown, in some embodiments of the drying device 10 for nuclear power plant steam generators, each first connecting component 11 includes a first connecting hoop 113, and the first connecting bars 111 are evenly distributed along the first connecting hoop 113 in a circular pattern;

[0068] each second connecting component 12 includes a second connecting hoop 123, and the second connecting bars 121 are evenly distributed along the second connecting hoop 123 in a circular pattern.

[0069] It can be understood that the first connecting hoop 113 is used to fix the first connecting bars 111 and ensure that they are evenly distributed along the circumference. This helps to improve the overall structural stability of the connecting component and ensure that the first connecting bars 111 can engage with the second connecting U-shaped card 122 evenly. The second connecting hoop 123 is used to fix the second connecting bars 121 and ensure that they are evenly distributed along the circumference. This also helps to improve the overall structural stability of the connecting component and ensure that the second connecting bars 121 can engage with the first connecting U-shaped card 112 evenly.

[0070] Each first connecting strip 111 and each second connecting strip 121 are evenly distributed along the circumference, which helps to ensure the balance and stability of the connection, and can also avoid local leakage caused by lack of locking in some parts. Similarly, it can also avoid damage at a certain position due to excessive local locking force.

[0071] As Figure 2 shown, in some embodiments of the drying device 10 for a nuclear power plant steam generator, the blowing assembly 22 includes a motor and a fan blade. The motor and the fan blade 221 are both arranged on the housing 21. The motor is drivingly connected to the fan blade 221, and the motor drives the fan blade 221 to rotate, so that the fan blade 221 drives the gas to be sucked in from outside the housing 21 and blown out through the air outlet 211.

[0072] It can be understood that the blowing assembly 22 can effectively generate an air flow and suck the gas in from outside the housing 21, and then blow it out through the air outlet 211, providing the necessary air flow supply for the subsequent heating and air guiding processes. This design not only ensures the smooth flow of the air flow, but also guarantees the efficient operation of the entire drying device.

[0073] As Figure 2 shown, in some embodiments of the drying device 10 for a nuclear power plant steam generator, the blowing device 2 further includes a volute 23. The volute 23 is arranged inside the housing 21, and the volute 23 is used to guide the gas flow direction to the air outlet 211.

[0074] It can be understood that through its unique spiral shape, the volute 23 can effectively guide the gas to flow from around the fan blade to the air outlet 211, thereby improving the efficiency and directivity of the gas flow. The volute 23 can effectively reduce the turbulence during the gas flow, make the gas flow more smoothly, and improve the directivity of the air flow.

[0075] As Figure 2 shown, in some embodiments of the drying device 10 for a nuclear power plant steam generator, the heating assembly 32 includes a plurality of heating elements 321, and each heating element 321 is arranged at intervals one by one along the length extension direction of the heating cylinder 31.

[0076] It can be understood that the heating assembly 32 includes a plurality of heating elements 321, and these heating elements 321 can be electric heating wires, resistance wires or other types of heating elements. Each heating element 321 is arranged at intervals one by one along the length direction of the heating cylinder 31. Such a layout helps to ensure that the gas is evenly heated during the entire heating process. The intervals between the heating elements 321 can ensure that the gas can fully contact each heating element 321 when passing through the heating cylinder 31, thereby achieving uniform heating.

[0077] It should be noted that through this embodiment, the heating component 32 can effectively heat the gas to the required temperature, ensuring that the gas can achieve the best effect in the subsequent drying process. This design of uniform heating not only improves the performance of the drying equipment but also increases its flexibility in various application scenarios.

[0078] As Figure 2 shown, in some embodiments of the drying equipment 10 of the nuclear power plant steam generator, the heating device 3 further includes a temperature probe 33, and the temperature probe 33 is arranged at the air outlet end 312.

[0079] It can be understood that the temperature probe 33 is arranged at the air outlet end 312 of the heating cylinder 31 for monitoring the temperature of the gas when it leaves the heating cylinder 31. The air outlet end 312 is the last flow path for the gas to leave the heating cylinder 31, so the final temperature of the gas after heating can be accurately measured.

[0080] It should be noted that the temperature probe 33 can feed back the detected temperature signal to the control system. The control system adjusts the working state of the heating element 321 according to the fed-back temperature signal to ensure that the gas reaches the required heating temperature. The control system includes a processor and a controller. The processor adjusts the current supplied to each heating element 321 according to the data measured by the temperature probe 33, so that the heating element 321 works and generates heat at a predetermined power to ensure the supply of air flow at the required temperature.

[0081] As Figure 2 shown, in some embodiments of the drying equipment 10 of the nuclear power plant steam generator, the outlet end 412 of the air duct 41 is provided with a mounting plate 413, and the mounting plate 413 is provided with a plurality of mounting holes 414 along the circumferential direction.

[0082] It can be understood that the mounting plate 413 can be configured as circular. The mounting plate 413 is used to connect to the evaporator or other facilities or equipment that need to be dried. The mounting plate 413 is provided with a through hole for the gas discharged from the outlet end 412 to flow through, so as not to form a flow obstacle to the air flow. The mounting holes 414 are used for bolts and the like to pass through.

[0083] Implementing the present utility model has the following beneficial effects:

[0084] The present utility model relates to a drying equipment for a nuclear power plant steam generator. In this drying equipment for a nuclear power plant steam generator, a detachable connection between the blowing device and the heating device is realized through one connecting device, and a detachable connection between the heating device and the air guiding device is realized through another connecting device. In this way, the equipment of the present utility model can be quickly connected to the area that needs to be dried, improving the connection efficiency and effectively improving the working efficiency. It also enables the blowing device and the heating device to be transported and used separately, improving the universality of the equipment application.

[0085] In addition, after connection through the connecting device, each first connecting strip will be correspondingly inserted and clamped into the second connecting U-shaped card, and each second connecting strip will be correspondingly inserted and clamped into the first connecting U-shaped card, so that the two components to be connected can be closely fitted and kept connected, that is, the mating surfaces of the two components will be closely abutted to form an effective seal. In this way, the full utilization of the airflow for drying can be ensured, and the drying efficiency is guaranteed.
