Description

Technical Field

[0001] This invention belongs to the field of energy recovery and utilization technology, and specifically relates to a waste heat recovery and condensate recovery device. Background Technology

[0002] In industrial production, steam is widely used in processes such as heating, humidification, and power driving. After completing its main functions, steam releases its latent heat of vaporization and is converted into high-temperature condensate. The sensible heat contained in this condensate accounts for about 20%-30% of the total heat of the steam, and is a valuable energy and water resource.

[0003] Existing technology CN223882315U discloses a waste heat boiler steam condensate recovery device, including a tank, a discharge pipe located at the top of the tank, a steam pipe connected to the tank, and a return pipe connected to the bottom of the tank. At least two condensation baffles are provided inside the tank along its height, with the outer periphery of each baffle contacting the inner wall of the tank. The baffles have vent holes. The connection point of the steam pipe to the tank is lower than the condensation baffles. The tank of this device is a monolithic structure, making disassembly and reassembly impossible. However, fouling may occur during waste heat recovery. If this fouling accumulates and cannot be cleaned in time, it will affect the normal operation of the device, thereby reducing the waste heat recovery efficiency. Summary of the Invention

[0004] This invention provides a waste heat recovery condensate recovery device, which aims to solve the problem that existing waste heat recovery condensate recovery devices cannot be disassembled and reassembled. However, dirt may be generated during the waste heat recovery process. Once a lot of dirt accumulates and cannot be cleaned in time, it will affect the normal use of the device and reduce the waste heat recovery efficiency.

[0005] This invention provides a waste heat recovery and condensate recovery device, comprising a tank with several guide grooves pre-formed on the inner wall of the tank, a discharge channel installed at the top of the tank, a steam channel and a return channel installed on one side of the lower end of the tank, with the steam channel located above the return channel, and three condensation baffles sequentially connected from top to bottom on the inner side of the tank, each baffle having several vent holes. The tank includes:

[0006] The lower can has a threaded end at the top of the can, and the leak-proof end at the top of the lower can is a slanted wall.

[0007] The upper tank has a pre-drilled threaded end 2 at its opening, which is connected to the threaded end. The upper and lower tanks are connected to each other by threads. The leak-proof end at the lower end of the upper tank is a sloping wall that contacts the leak-proof end at the upper end of the lower tank.

[0008] The protective unit includes an outer cylinder with a pair of outer cylinders. Each pair of outer cylinders is movably connected to the outer peripheral walls of the upper and lower tanks. A restraint opening is reserved on the inner side of the outer cylinder on the side of the upper tank. The upper tank contacts each other via a restraint platform fixed to its outer peripheral wall and the inner wall of the restraint opening. The edge of the outer cylinder is conical. A protective plate is movably mounted on the outer cylinder via a tilted plate fixed to its outer wall. The protective plate is used to cover the leak-proof ends of the upper and lower tanks. Several protective plates are mounted. A movable part for shortening several protective plates is installed on the outer wall of the outer cylinder.

[0009] The movable part includes a ball head fixed to the outer wall of the protective plate, and a rotating ring screwed to the edge of the outer cylinder. A connecting strip is movably installed on the rotating ring via a shaft fixed to one side of its outer side. The side of the connecting strip farther from the shaft is screwed to the outer wall surface of the ball head.

[0010] Furthermore, magnets are installed on the sidewalls of the protective plates, and adjacent protective plate sidewalls are connected by magnets. Magnets are installed on the side of the skewed plate that is farther from the central axis of the outer cylinder, and magnets are installed on the side of the protective plate that is farther from the central axis of the outer cylinder.

[0011] Furthermore, an assembly chamber is reserved on the inner wall of the outer cylinder on one side of the upper tank, and a leak-proof part is installed inside the assembly chamber.

[0012] Furthermore, the leak-proof part includes a leak-proof plate, and the side of the leak-proof plate that is farther from the central axis of the outer cylinder is fixedly connected to a connecting column. The outer wall of the connecting column is movably connected to the inside of the outer cylinder on the side of the upper tank.

[0013] Furthermore, the anti-leak plate is fixed to the tilting platform near the connecting column. A vertical bar is fixed to the lower wall of the constraint platform. The lower end of the vertical bar passes through the constraint opening and extends into the assembly chamber to contact the outer wall of the tilting platform. The bottom of the vertical bar is the tilting wall. A spiral beryllium copper wire 2 is installed inside the constraint opening and contacts the bottom wall of the constraint platform.

[0014] Furthermore, a leak-proof port A is reserved on the outer ring surface of the lower tank, and a leak-proof port B is reserved on the outer ring surface of the upper tank. The leak-proof plate is fixed to the leak-proof ring on the side close to the central axis of the outer cylinder.

[0015] Furthermore, an interlocking interface is reserved on the outer ring surface of the upper tank, and an interlocking platform is movably installed on the inner wall of the interlocking interface. A spiral beryllium copper wire is installed in the interlocking interface and contacts the inner wall of the interlocking platform.

[0016] Furthermore, a constraint rod is fixed to the upper wall of the outer cylinder on the lower tank side, a pusher is fixed to the lower wall of the rotating ring on the lower tank side, the lower wall of the pusher passes through the outer cylinder and extends to its outer wall, and a pusher seat is fixed to the outer wall of the rotating ring on the upper tank side.

[0017] Furthermore, the inner sides of the lower tank and the upper tank are fixedly connected to constraint rings. The lower end of the top condensing baffle and the upper end of the bottom condensing baffle are both fixedly connected to several support columns. The support columns are inserted into the side of the middle condensing baffle. After the support columns assemble the three condensing baffles together, the condensing baffles on the upper and lower sides are respectively in contact with the corresponding constraint rings.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The upper and lower tanks of this invention can be assembled and disassembled, which facilitates regular cleaning of their interiors, prevents the accumulation of dirt inside the tanks and on the condenser baffles, and ensures the normal use of the device and the efficiency of waste heat recovery.

[0020] 2. With the installation of the protective plates and the movable part, when the upper and lower cans are in an unassembled state, the leak-proof ends of the lower and upper cans are each covered by the corresponding protective plates. Within each group, the adjacent surfaces of the adjacent protective plates are attracted to each other by the suction force. The lower wall surface of the upper can's protective plate near the central axis of the outer cylinder is close to the leak-proof end of the upper can facing downwards and covers this leak-proof end. The upper wall surface of the lower can's protective plate near the central axis of the outer cylinder is close to the leak-proof end of the lower can facing downwards and covers the threaded end of the lower can's bottom together with the leak-proof end. Within each group, several protective plates form a closed ring-shaped conical structure, which completely surrounds the leak-proof end and the threaded end, isolating external debris to prevent the leak-proof end and the threaded end from being damaged by impact or scratch during transportation or placement. At the same time, it prevents debris from falling into the leak-proof area, increases the working cycle of the equipment, and ensures the leak-proof function during assembly.

[0034] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] Reference Figure 1 This invention provides a waste heat recovery and condensate recovery device, comprising a tank 1, with several guide grooves reserved on the inner wall of the tank 1, a discharge channel 2 installed on the top of the tank 1, a steam channel 3 and a return channel 4 installed on one side of the lower end of the tank 1, the steam channel 3 being above the return channel 4, and three condensation baffles 5 being sequentially connected from top to bottom on the inner side of the tank 1, with several air holes reserved on the condensation baffles 5.

[0037] During operation, the steam passage 3 is connected to the steam discharge passage. Steam enters the tank 1 through the steam passage 3. As the steam flows out of the tank 1 through the discharge passage 2, it will come into contact with the condensation baffles 5 set at different heights inside the tank 1 in sequence, thus condensing. The condensed water droplets flow into the guide groove provided on the inner wall of the tank 1 through the concave part of the condensation baffle 5, flow to the bottom of the tank 1 through the guide groove, and then flow out through the return passage 4, thus being reused.

[0038] Example 2

[0039] Reference Figures 2-10 The difference from Embodiment 1 is that the tank 1 includes: The lower tank 6 has a pre-reserved threaded end at the upper end of the opening. The leak-proof end of the upper tank 6 is a slanted wall, which helps to enhance the tightness of the leak-proof.

[0040] The upper tank 7 has a pre-drilled threaded end 2 at its opening, which connects to the threaded end. The upper tank 7 and the lower tank 6 are threaded together for assembly and disassembly. The leak-proof end at the lower end of the upper tank 7 is a sloping wall that contacts the leak-proof end at the upper end of the lower tank 6. Together with the leak-proof end of the sloping wall of the lower tank 6, they form a leak-proof layer.

[0041] The protection unit 8 includes an outer cylinder 81, on which a pair of outer cylinders 81 are mounted, each being movably connected to the outer peripheral walls of the upper tank 7 and the lower tank 6. A constraint opening 811 is provided on the inner side of the outer cylinder 81 located on the side of the upper tank 7. The upper tank 7 contacts the inner wall of the constraint opening 811 via a constraint platform 71 fixed to its outer peripheral wall, thereby constraining the vertical movement of the outer cylinder 81. The edge of the outer cylinder 81 is conical. A protective plate 82 is movably mounted on the outer cylinder 81 via a tilting plate 810 fixed to its outer wall. The protective plate 82 is used to cover the leak-proof ends of the upper tank 7 and the lower tank 6 to prevent debris from entering. Several protective plates 82 are mounted. A movable part 83 is provided on the outer wall of the outer cylinder 81 for shortening the protective plates 82.

[0042] The movable part 83 includes a ball head fixed to the outer wall of the protective plate 82. A rotating ring 831 is screwed onto the edge of the outer cylinder 81. A connecting strip 832 is movably mounted on the rotating ring 831 via a shaft fixed to one side of its outer side. The side of the connecting strip 832 furthest from the shaft is screwed onto the outer wall of the ball head. When the rotating push seat 8312 or the push table 8311 is used, the rotating ring 831 rotates accordingly. Through the linkage of the connecting strip 832, the protective plate 82 is driven to move along the tilt plate 810, so as to achieve the purpose of closing and opening the protective plate 82. When the rotating push seat 8312 makes the rotating ring 831 rotate in the forward direction, the connecting strip 832 pulls the protective plate 82 to move along the tilt plate 810 towards the side furthest from the central axis of the outer cylinder 81, and the protective plate 82 opens. When the rotating push seat 8312 is rotated in the reverse direction, the protective plate 82 closes.

[0043] Magnets are installed on the sidewalls of the protective plate 82, and adjacent protective plates 82 are connected by magnets. Magnets are installed on the side of the inclined plate 810 furthest from the central axis of the outer cylinder 81, and magnets are installed on the side of the protective plate 82 furthest from the central axis of the outer cylinder 81. When the protective plate 82 is closed, adjacent protective plates 82 are connected by magnets, maintaining a stable contact state. When the protective plate 82 is open, the magnets on the protective plate 82 and the inclined plate 810 work together to further enhance the stability of the protective plate 82 in the open state.

[0044] An assembly chamber 812 is reserved on the inner wall of the outer cylinder 81 on one side of the upper tank 7. A leak-proof part 84 is installed inside the assembly chamber 812 to perform a second layer of leak prevention.

[0045] The leak-proof part 84 includes a leak-proof plate 841. The side of the leak-proof plate 841 that is farther from the central axis of the outer cylinder 81 is fixedly connected to a connecting post 842. The outer wall of the connecting post 842 is movably connected to the inside of the outer cylinder 81 located on the upper tank 7 side. The side of the connecting post 842 that is closer to the central axis of the outer cylinder 81 is higher than the side that is farther from the central axis of the outer cylinder 81. Under its own weight, it can return to its original position.

[0046] The leak-proof plate 841 is fixedly connected to the inclined platform 843 near the connecting column 842. A vertical bar 844 is fixedly connected to the lower wall of the restraint platform 71. The lower end of the vertical bar 844 passes through the restraint opening 811 and extends into the assembly chamber 812, contacting the outer wall of the inclined platform 843. The bottom of the vertical bar 844 is an inclined wall. A spiral beryllium copper wire 845 is installed inside the restraint opening 811, contacting the bottom wall of the restraint platform 71. When the outer cylinder 81 moves downward, the restraint platform 71 moves within the restraint opening 811, compressing the spiral beryllium copper wire 845 to shorten, and the vertical bar 844 touches the inclined platform 843. The inclined wall drives the leak-proof plate 841 to move towards the side closer to the central axis.

[0047] Leak-proof opening A61 is reserved on the outer ring surface of the lower tank 6, and leak-proof opening B72 is reserved on the outer ring surface of the upper tank 7. Leak-proof plate 841 is fixed to leak-proof ring 846 on one side near the central axis of outer cylinder 81. A pair of leak-proof rings 846 are installed, and the outer ring surface of the pair of leak-proof rings 846 respectively contacts the inner ring surface of leak-proof opening A61 and leak-proof opening B72 to achieve the function of leak prevention.

[0048] An insertion interface 73 is pre-reserved on the outer ring surface of the upper tank 7. An insertion platform 731 is movably installed on the inner wall of the insertion interface 73. A spiral beryllium copper wire 732 is installed in the insertion interface 73 and contacts the inner wall of the insertion platform 731. The insertion platform 731 can be moved out with the cooperation of the spiral beryllium copper wire 732 to constrain the position of the outer cylinder 81 and prevent it from changing without control.

[0049] A constraint rod 85 is fixedly connected to the upper wall of the outer cylinder 81 on the lower tank 6 side. A pusher platform 8311 is fixedly connected to the lower wall of the rotating ring 831 on the lower tank 6 side. The lower wall of the pusher platform 8311 passes through the outer cylinder 81 and extends to its outer wall. A pusher seat 8312 is fixedly connected to the outer wall of the rotating ring 831 on the upper tank 7 side. The pusher platform 8311 and the pusher seat 8312 facilitate the user to rotate the rotating ring 831 to achieve the purpose of closing and opening the maintenance plate 82.

[0050] The leak-proof end at the bottom of the upper tank 7 is a downward-extending, skewed structure, with the side of the leak-proof end of the upper tank 7 closer to the central axis located below the side farther from the central axis. The lower end of the outer cylinder 81 of the upper tank 7 is a downward-extending conical structure. A set of maintenance plates 82 at the top is movably connected via skewed plates 810 fixed to the lower wall of the outer cylinder 81.

[0051] The leak-proof end at the top of the lower tank 6 is a downward-sloping structure, with the side of the lower tank 6 closest to the central axis located below the side furthest from the central axis. The top of the outer cylinder 81 located at the lower tank 6 is a downward-sloping conical structure, and a set of maintenance plates 82 at the bottom is movably connected via a sloping plate 810 fixed to the upper wall of the outer cylinder 81.

[0052] In the initial configuration, the lower tank 6 and the upper tank 7 are separated. The outer cylinder 81, the protective plates 82, and the movable part 83 are each equipped with two sets: one set paired with the lower tank 6, and the other set paired with the upper tank 7. Both sets of protective plates 82 are in a folded configuration. Each set of protective plates 82 contains two pairs. Within each set, the sidewalls of adjacent protective plates 82 are attracted to each other. Each set of protective plates 82 is assembled into a closed conical structure. In the folded configuration, the protective plates 82 are close to the central axis of the outer cylinder 81.

[0053] At this moment, the lower wall surface of the corresponding lower tank 6, which is close to the central axis of the outer cylinder 81, and the leak-proof end of the lower tank 6 facing downwards approach each other, thus covering the leak-proof end of the lower tank 6; the upper wall surface of the corresponding upper tank 7, which is close to the central axis of the outer cylinder 81, and the leak-proof end of the upper tank 7 facing downwards approach each other, thus covering the leak-proof end of the upper tank 7, and also covering and protecting the threaded end at the bottom of the upper tank 7.

[0054] The outer cylinder 81 of the corresponding upper tank 7 is located near the leak-proof end of the upper tank 7 within its trajectory range. The spiral beryllium copper wire 845 in the restraint port 811 is in an extended state. The upper wall surface of this set of protective plates 82 is in contact with the lower wall surface of this set of outer cylinders 81 and the leak-proof end of the bottom of the upper tank 7. The outer cylinder 81 of the corresponding lower tank 6 is located near the leak-proof end of the lower tank 6 within its trajectory range. The lower wall surface of this set of protective plates 82 is in contact with the upper wall surface of this set of outer cylinders 81 and the leak-proof end of the top of the lower tank 6.

[0055] Furthermore, the spiral beryllium copper wire 732 in the insertion interface 73 is in a shortened state, and the outer wall surface of the insertion platform 731 and the inner surface of the outer cylinder 81 on one side of the upper tank 7 are in contact with each other.

[0056] The connection action between the lower can 6 and the upper can 7: During docking, the user first rotates the push platform 8311, causing the rotating ring 831 located at the lower tank 6 to rotate. The push platform 8311 drives the rotating ring 831 to rotate clockwise at the top of the outer cylinder 81. The shaft on the outer side of the rotating ring 831 rotates in conjunction with this rotation, causing the connecting strip 832 to move closer to the outside of the shaft. At this moment, the connecting strip 832, through the ball head inside, pulls the protective plate 82 along the tilting plate 810 towards the side farther from the central axis of the outer cylinder 81. The protective plate 82 moves along the conical wall of the outer cylinder 81, and while moving towards the side farther from the central axis of the outer cylinder 81, it also moves upwards, resulting in a tilted movement. After the protective plate 82 extends, the distance between adjacent protective plates 82 increases, the adjacent surfaces of the protective plates 82 are no longer tightly connected, and the protective plate 82 and the clamping end of the tilting plate 810 cooperate to allow the protective plate 82 to extend smoothly. The protective plate 82 no longer covers the leak-proof end of the lower tank 6. At this moment, the lower wall of the extended protective plate 82 is no longer in contact with the leak-proof end at the top of the lower tank 6, and is only disconnected from the upper wall of the corresponding outer cylinder 81.

[0057] Next, the outer cylinder 81 is moved along the outer circumference of the lower tank 6, so that the protective plate 82 is away from the leak-proof end at the top of the lower tank 6. At this moment, the outer cylinder 81 is at the bottom of its trajectory area, and the top of the lower tank 6 is fully exposed.

[0058] Rotating the pusher seat 8312 causes the rotating ring 831 located at the upper tank 7 to rotate. The pusher seat 8312 drives the rotating ring 831 to rotate clockwise at the bottom of the outer cylinder 81. The shaft on the outer wall of the rotating ring 831 rotates together, driving the connecting bar 832 to move in an arched trajectory near the outside of the shaft. At this time, the connecting bar 832, through the ball head rolling inside, pulls the protective plate 82 to move along the outer wall of the inclined plate 810 towards the side farther from the central axis of the outer cylinder 81. The protective plate 82 moves along the conical surface of the outer cylinder 81, and also moves upwards during the movement towards the side farther from the central axis of the outer cylinder 81, all in an inclined movement. After the protective plate 82 is extended, the distance between adjacent protective plates 82 increases, the adjacent surfaces of the protective plates 82 lose their suction connection, and the suction surfaces of the protective plate 82 and the inclined plate 810 cooperate to allow the protective plate 82 to maintain its extended shape smoothly after being extended. At this moment, the lower wall of the extended protective plate 82 no longer contacts the leak-proof end at the top of the upper tank 7, and only contacts the lower wall of the corresponding outer cylinder 81.

[0059] A spiral beryllium copper wire 845 is installed in the constraint opening 811. The top of the spiral beryllium copper wire 845 is connected to the lower wall of the constraint platform 71, and the lower end is in contact with the lower end of the inner surface of the constraint opening 811. Under the cooperation of the deformation force of the spiral beryllium copper wire 845, the outer cylinder 81 is still at the bottom of its trajectory area. The lower wall of the vertical bar 844 is no longer in contact with the inclined wall of the inclined platform 843, leaving a gap in the vertical direction.

[0060] Then, align the threaded end two of the upper can 7 with the threaded end one of the lower can 6, and then twist the upper can 7 to connect it with the lower can 6. A constraint rod 85 is fixed to the upper wall of the corresponding outer cylinder 81 of the lower can 6. During the connection, as the upper can 7 rotates, the lower wall of the rotating ring 831 on the top side gradually disengages from the upper wall of the constraint rod 85. When the upper can 7 rotates continuously, the lower can 6 and the pair of outer cylinders 81 remain in a static position, with only the upper can 7 moving vertically downwards. The constraint platform 71 moves relative to the constraint opening 811 of the upper can 7, and the distance between the constraint platform 71 and the lower end of the constraint opening 811 gradually decreases, compressing the spiral beryllium copper wire 845 and shortening it.

[0061] Furthermore, the vertical bar 844 moves downward along with the constraint table 71, moving into the assembly chamber 812 and contacting the tilting table 843. Because the lower wall of the vertical bar 844 is tilted, during the downward movement of the vertical bar 844, the tilting table 843 is driven by the tilting wall to move towards the side closer to the central axis of the upper tank 7 and the lower tank 6, thereby driving the leak-proof plate 841 and the connecting column 842 to move.

[0062] After the threaded end 2 of the upper can 7 and the threaded end 1 of the lower can 6 are fully tightened, the lower can 6 and the inclined leak-proof end of the upper can 7 come into contact, forming a leak-proof layer. At this moment, when the leak-proof plate 841 moves to the appropriate position with the cooperation of the vertical strip 844, the pair of leak-proof rings 846 on its inner wall surface come into contact with the leak-proof openings A61 and B72 respectively, achieving the purpose of leak prevention.

[0063] At this moment, the outer cylinder 81 at the top is at the very top of the trajectory area of ​​the outer wall surface of the upper tank 7. The spiral beryllium copper wire 845 is in a compressed and shortened state. The fitting platform 731 in the fitting interface 73 is no longer constrained by the annular surface of the outer cylinder 81. With the cooperation of the spiral beryllium copper wire 732, it is in a stretched state. The lower wall surface of the fitting platform 731 contacts the top of the outer cylinder 81, so that the outer cylinder 81 stops here, ensuring the leak-proof function inside the tank.

[0064] During disassembly, the user presses down on the insert platform 731, allowing it to retract into the insert interface 73, thus releasing the constraint on the outer cylinder 81. Then, the threaded connection between the upper can 7 and the lower can 6 is unscrewed. Under the deformation force of the spiral beryllium copper wire 845, the lower end of the outer cylinder 81, which was at the top, reappears near the leak-proof end at the bottom of the upper can 7. After the pressure of the sloping wall of the vertical bar 844 is released, the leak-proof plate 841 and the leak-proof ring 846 on its inner wall surface no longer make tight contact with the inside of the leak-proof openings A61 and B72. The leak-proof plate 841 also slowly moves away from the leak-proof ends of the upper can 7 and the lower can 6, and both layers of leak-proof structure are opened.

[0065] Finally, the reverse rotation of the push seat 8312 and the push platform 8311, along with the shaft on the outer wall of the rotating ring 831, causes the connecting bar 832 to move in an arched trajectory near the outside of the shaft. At this moment, the connecting bar 832, through the ball head rolling inside, pulls the protective plate 82 along the outer wall of the inclined plate 810 towards the side closer to the central axis of the outer cylinder 81. The protective plate 82 moves along the conical surface of the outer cylinder 81, and also moves downwards while moving towards the central axis of the outer cylinder 81, all in an inclined motion. After the protective plate 82 shrinks, the suction ends of the protective plate 82 and the inclined plate 810 release the suction, and the distance between adjacent protective plates 82 decreases until they are fully in contact under the cooperation of the suction force. Both sets of protective plates 82 merge into a circular conical structure, providing cover and protection for the leak-proof ends of the upper tank 7 and the lower tank 6.

[0066] Protection unit 8 has the following advantages: Advantage 1: When the lower tank 6 and upper tank 7 are in their unassembled state, the leak-proof ends of the upper tank 7 and lower tank 6 are each covered by the corresponding protective plates 82. Within each assembly, the adjacent surfaces of adjacent protective plates 82 are attracted to each other by the suction force. The lower wall surface of the lower tank 6's protective plate 82, which is close to the central axis of the outer cylinder 81, is close to the leak-proof end of the lower tank 6 facing downwards, and covers this leak-proof end. The upper tank 7's protective plate 82, which is close to the central axis of the outer cylinder 81... The upper wall surface and the leak-proof end extending downward from the bottom of the upper tank 7 are close to each other, and the threaded end 2 at the bottom of the upper tank 7 and the leak-proof end are covered and protected together. In each group, several protective plates 82 form a closed ring-shaped conical structure, which then completely surrounds the leak-proof end and the threaded end 2, isolates external debris, and prevents the leak-proof end and the threaded end 2 from being damaged by impact or scratch during transportation or placement. At the same time, it prevents debris from falling into the leak-proof range, increases the working cycle of the equipment, and ensures the leak-proof function during assembly. Advantage 2: During assembly, the rotating ring 831 is driven to rotate by the rotating push table 8311 or the push seat 8312, which in turn causes the connecting bar 832 to pull the protective plate 82 to move and extend along the inclined plate 810 to the side farther from the central axis of the outer cylinder 81, so that the protective plate 82 is away from the leak-proof end. Then, the outer cylinder 81 is moved along the outer ring surface of the lower tank 6 to change its length direction. Finally, the threaded end of the upper tank 7 is twisted to align with the threaded end of the lower tank 6 to achieve docking. The overall assembly is easy to operate and can be completed without the assistance of tools. Assembly and disassembly are more convenient, which in turn makes it easier to clean the inside of the tank 1 and the condensation baffle 5. Advantage 3: After the threaded end 2 of the upper tank 7 and the threaded end 1 of the lower tank 6 are fully tightened, the fitting platform 731 in the fitting interface 73 extends under the cooperation of the spiral beryllium copper wire 732. The lower wall of the fitting platform 731 contacts the top of the outer cylinder 81 on this side, so that the outer cylinder 81 stops here, ensuring the leak-proof function of the tank. When disassembling, press the fitting platform 731 to retract it into the fitting interface 73, which can release the constraint on the outer cylinder 81. Then unscrew the threaded connection of the upper tank 7 and the lower tank 6. This tightening and disassembly action is very convenient, which can ensure the stability in the connection situation and the convenience during disassembly, and then facilitate the cleaning of the inside of the tank 1 and the condensation baffle 5. Advantage 4: The leak-proof end at the bottom of the upper tank 7 is a downward-extending sloping wall, and the leak-proof end at the top of the lower tank 6 is a downward-sunken sloping wall. Furthermore, the leak-proof ends are located below the side furthest from the central axis on the side closest to the central axis. During the tightening of the threaded connection, the sloping walls of the leak-proof ends form a contact and conical pressure effect with each other. The pressure effect of the contact increases along with the torsional action. Compared with the existing leak-proof structure, the leak-proof function of the fluid is enhanced, and it can be applied in various environments. The leak-proof ends of the lower tank 6 and the upper tank 7 are compatible with each other and can perform guidance during assembly. They can self-correct the axial offset of the lower tank 6 and the upper tank 7 to prevent the leak-proof ends from not contacting tightly due to offset. This facilitates rapid assembly and allows the lower tank 6 and the upper tank 7 to make more accurate contact during assembly, ensuring the leak-proof function. Advantage 5: The inclined walls of the lower tank 6 and the upper tank 7 at the leak-proof end contact to form a leak-proof layer; and with the cooperation of the vertical strip 844, the pair of leak-proof rings 846 on the inner wall of the leak-proof plate 841 contact the inside of the leak-proof port A61 and the leak-proof port B72 respectively to achieve the purpose of leak prevention. Compared with the current single-layer leak-proof structure, the reliability and stability of leak prevention are enhanced. The double-layer leak-proof structure is adopted. When the first layer of leak-proof structure is damaged due to long-term operation, the other leak-proof structures can work immediately to prevent sudden fluid leakage.
