Description

Technical Field

[0001] This utility model relates to the technical field of steam condensate recovery equipment, and in particular to a steam condensate tank. Background Technology

[0002] Steam condensate refers to the liquid water formed after water vapor undergoes a condensation process. It typically flows out from the collection pan below the evaporator of the equipment. Steam condensate is of high value, so many manufacturers collect it. Steam condensate buffers are usually used for collection; however, existing steam condensate buffers have relatively simple internal structures and limited functions, requiring improvement.

[0003] The technical solution disclosed in Chinese Patent Publication No. CN221981695U removes impurities from condensate by incorporating a buffer filtration mechanism and a tank body. This solves the problem of impurities in condensate during existing condensate recovery processes, while minimizing impact on the inner wall of the storage tank and preventing damage. The inclusion of a vent pipe prevents excessive water vapor buildup in the tank, thus avoiding pressure increases and ensuring condensate flows smoothly into the tank.

[0004] However, the device still has shortcomings: when the conical filter is in operation, impurities are easily trapped in the filter holes due to pressure, which can seal the filter holes and reduce the filtration efficiency of the conical filter. At this time, the machine needs to be stopped for manual cleaning, which is time-consuming, labor-intensive, and affects work efficiency. Utility Model Content

[0014] Preferably, a liquid level sensor is installed inside the tank, and a controller is installed on the frame. The controller is electrically connected to the liquid level sensor and the control valve.

[0015] Preferably, the bottom of the storage hopper is provided with a guide tube communicating with its interior. The inner diameter of the guide tube is the same as the outer diameter of the external threaded tube, and the top end of the external threaded tube is inserted into the guide tube and slidably connected to its inner wall.

[0016] Preferably, an annular groove A, coaxial with the fixed tube, is provided on the outer wall of the fixed tube, and a through hole A is provided on the fixed tube to connect the annular groove A and its internal channel. The movable tube is located inside the annular groove A and is sealed to its inner wall. A through hole B is provided on the movable tube, and the through hole B remains connected to the through hole A when the movable tube is rotating. The output end of the gas collecting hood is connected to the through hole B.

[0020] Compared with the prior art, the present invention has the following beneficial technical effects:

[0021] By setting up a cooperative structure consisting of an internal threaded pipe, an external threaded pipe, a fixed pipe, a movable pipe, a gas collecting hood, an impeller, gears, and an external gear ring, the device utilizes the flowing water to drive the impeller to rotate when water is introduced, which in turn drives the movable pipe and the gas collecting hood to rotate. While rotating, the gas collecting hood passes through each row of filter holes in sequence, causing the gas pressure inside the tank to increase. Excess gas, after passing through the filter holes of the filter cylinder, flows sequentially along the gas collecting hood, through hole B, through hole A, the fixed pipe, and the external threaded pipe, and is discharged to the outside through the external threaded pipe. During the exhaust process, the gas backflows through the filter holes, flushing out impurities that are clogging them. Furthermore, in this structure, the external threaded pipe is spirally connected to the internal threaded pipe, allowing the external threaded pipe to detach from the fixed pipe and enter the guide pipe while rotating when the machine stops. At this time, impurities accumulated in the storage hopper are automatically discharged along the external threaded pipe. Attached Figure Description

[0028] Example 1

[0029] like Figures 1-5As shown, this utility model proposes a steam condensate tank, comprising a tank body 3, an externally threaded pipe 6, a sealing cap 7, a fixed pipe 11, a movable pipe 12, a volute 15, and a transmission assembly. The tank body 3 is provided with an outlet pipe 4 communicating with its interior, and a control valve is provided on the outlet pipe 4 to control the on / off state of its interior. An internally threaded pipe 5 communicating with its interior is provided at the bottom of the tank body 3. The externally threaded pipe 6 extends into the tank body 3 along the inner side of the internally threaded pipe 5 and is spirally connected to the internally threaded pipe 5. The sealing cap 7 is connected to the tank body 3, and a filter cylinder 8 is coaxially arranged at the bottom of the sealing cap 7, with the bottom of the filter cylinder 8 communicating with a storage hopper 9. The sealing cap 7 is provided with a feed hole 71 communicating with the interior of the filter cylinder 8. A guide pipe 10 communicating with the interior of the storage hopper 9 is provided at the bottom of the storage hopper 9, with the inner diameter of the guide pipe 10 being the same as the outer diameter of the externally threaded pipe 6, and the top end of the externally threaded pipe 6 being inserted into the guide pipe 10 and slidably connected to its inner wall. The fixed tube 11 is coaxially connected to the sealing cover 7 and located inside the filter cartridge 8. The lower end of the fixed tube 11 is suspended above the discharge port of the storage hopper 9. An annular groove A111, coaxial with the fixed tube 11, is provided on the outer wall of the fixed tube 11. A through hole A112 is provided on the fixed tube 11, connecting the annular groove A111 and its internal channel. The movable tube 12 is located inside the annular groove A111 and is sealed to its inner wall. A through hole B121 is provided on the movable tube 12. The through hole B121 remains connected to the through hole A112 when the movable tube 12 is rotating. The output end of the gas collecting hood 13 is connected to the through hole B121. An annular groove B113 is provided on the inner wall of the fixed tube 11 below the through hole A112. The top end of the externally threaded tube 6 is inserted into the annular groove B113 and slidably connected to its inner wall. The inner diameter of the externally threaded tube 6 is the same as the inner diameter of the fixed tube 11. The movable tube 12 is sleeved on the fixed tube 11. A gas collecting hood 13, which is always in communication with the inside of the fixed tube 11, is installed on the movable tube 12. The open end of the gas collecting hood 13 is slidably connected to the inner wall of the filter cartridge 8. The volute 15 is connected to the sealing cover 7. The output end of the volute 15 covers the outside of the feed hole 71, and the output end of the volute 15 is inserted into the inside of the filter cartridge 8. The input end of the volute 15 is connected to the feed pipe 16. An impeller 18, rotatably connected to the volute 15, is installed inside the volute 15. The transmission assembly includes an external gear ring 14 and a gear 19. A rotating shaft 17 is provided inside the feed hole 71 and is rotatably connected to the sealing cover 7. The rotating shaft 17 is coaxially connected to the impeller 18. The gear 19 is coaxially connected to the rotating shaft 17. The external gear ring 14 is sleeved on the movable tube 12 and coaxially connected to it. The external gear ring 14 meshes with the gear 19. A buffer cover plate 20 is provided on the fixed tube 11. The external gear ring 14 and the gear 19 are both located below the buffer cover plate 20. The rotating shaft 17 is rotatably connected to the buffer cover plate 20. The transmission assembly drives the impeller 18 and the movable tube 12.

[0030] In this embodiment, the external threaded pipe 6 is first rotated to ensure that its top end is inserted into the annular groove B113. The condensate pipe is then connected, and the condensate enters the volute 15 along the feed pipe 16 and is filtered by the filter cartridge 8 before being retained in the tank 3. Since the water and steam collide with the buffer cover plate 20 after entering the filter cartridge 8, the high-speed flowing water and steam are effectively prevented from impacting the filter cartridge. The flowing water and steam drive the impeller 18 to rotate, which in turn drives the shaft 17 and gear 19 to rotate. The gear 19 drives the external gear ring 20 and the movable tube 12 to rotate, which in turn causes the gas collecting hood 13 to rotate around the axis of the fixed tube 11. While rotating, the gas collecting hood 13 scrapes away impurities on the inner wall of the filter cylinder 8, preventing them from blocking the filter holes. Simultaneously, when the gas collecting hood 13 passes through a row of filter holes, since the gas in the tank 3 can only flow along the gas collecting hood 13 and the fixed tube 11, the gas in the tank 3 backflows through the filter holes, pushing the impurities blocking the filter holes into the gas collecting hood 13 and into the fixed tube 11. After entering the fixed tube 11, the impurities and air are directly discharged along the external threaded tube 6. When the equipment stops, the external threaded tube 6 is rotated so that its opening is flush with or lower than the edge of the discharge port of the storage hopper 9. At this time, the impurities collected in the storage hopper 9 are directly discharged along the external threaded tube 6 without disassembling the equipment, making operation simple and convenient.

[0031] Example 2

[0032] like Figure 1 and Figure 2 As shown, the steam condensate tank proposed in this utility model, compared with Embodiment 1, has a tank body 3 connected to a frame 1, a water storage tank 2 installed on the frame 1, and the input end of the water storage tank 2 connected to the output end of the water outlet pipe 4. A liquid level sensor 31 is installed inside the tank body 3, and a controller is installed on the frame 1, with the controller electrically connected to the liquid level sensor 31 and a control valve.

[0033] In this embodiment, when the liquid level sensor automatically detects that the condensate level in the tank 3 is high (the liquid level does not exceed the bottom of the filter cartridge 8), the control valve opens, and the water in the tank 3 enters the water storage tank 2. This structure uses the control valve to shut off the water outlet pipe 4, so that the flow direction of the gas in the tank 3 can only be towards the inside of the gas collection hood 13.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
