Description

Technical Field

[0001] This utility model relates to the field of steam conveying technology, and in particular to a steam condensate recovery device. Background Technology

[0002] Condensate is generated during steam transport, and its accumulation affects the efficient transmission of steam. Conventional float-type steam traps are used to drain excess condensate, with the drain opening controlled by the up-and-down movement of a float. However, float-type steam traps have limited drainage capacity and cannot completely remove all condensate, leaving some water inside. If not used for extended periods, this water accumulation can lead to corrosion, and the damp environment can also promote bacterial growth, further contaminating the steam system. Furthermore, steam often carries impurities such as fibers and sludge, which are difficult to expel through the float-type steam trap due to the accumulated water, causing blockages. Once a blockage occurs, the steam trap will malfunction, requiring immediate shutdown for cleaning and repair. This is not only time-consuming and labor-intensive but also severely impacts the continuity and stability of steam transport, making it difficult to meet the high-efficiency requirements of industrial production.

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0031] like Figures 1-8As shown is a steam condensate water recovery device, which comprises a box structure 1, a partition 2, and a drainage assembly. The box structure 1 has a cavity inside, and a top plate 13 is formed on the top. In this embodiment, the box structure 1 comprises an upper box and a lower box. The upper box and the lower box are combined to form the box structure 1. The aforementioned partition 2 is installed inside the box structure 1 to separate the inside of the box structure 1 into an upper space 11 and a lower space 12. The partition 2 is processed with communication holes 21 that communicate the upper space 11 and the lower space 12. The number of communication holes 21 is determined according to the actual design. Through the communication holes 21, the condensate water can enter the lower space 12 from the upper space 11. The top plate 13 is processed with a steam inlet 16 and a steam outlet 17. The steam inlet 16 and the steam outlet 17 are respectively communicated with the upper space 11, and steam can enter the upper space 11 through the steam inlet 16 and then be discharged from the steam outlet 17. The steam inlet 16 and the steam outlet 17 form a steam conveying path. A filter plate 7 is installed in the upper space 11 on the steam conveying path. The filter plate 7 is distributed with filter holes 71. In the steam conveying process, the wet steam with water is intercepted by the filter plate 7, the water is intercepted and gathered as water droplets, and the steam continues to flow after passing through the filter holes 71 on the filter plate 7, thereby realizing vapor-liquid separation. In addition, the filter plate 7 can filter the impurities such as fiber hair and particulate matter carried by the steam.

[0032] The aforementioned drainage components are arranged corresponding to the connecting hole 21. The drainage components include a connecting piece 3, a float 4, a counterweight 43, a corrugated pipe 5, a first pull rope 41, and a second pull rope 42. The connecting piece 3 is arranged in the lower space 12 and is fixedly connected to the partition 2. A cavity 31 is machined on the connecting piece 3 to connect with the connecting hole 21. A drainage channel 32 is machined on the bottom surface of the cavity 31. The drainage channel 32 connects to the lower space 12. Through the above structural design, condensate from the upper space 11 can enter the cavity 31 through the connecting hole 21 and then enter the lower space 12 through the drainage channel 32. The aforementioned float 4 is adapted to the cavity 31 and is arranged within it. It has a designed weight; when a certain amount of water accumulates in the cavity 31, the float 4 floats upwards, and when some water is discharged from the cavity 31, the float 4 descends. The float 4 is raised and lowered to have two positions: an upward position away from the drain channel 32 and a downward position that closes the drain channel 32. In the upward position, water in the cavity 31 can be discharged through the drain channel 32. In the downward position, the float 4 closes the drain channel 32. Specifically, the bottom surface of the cavity 31 is a spherical surface adapted to fit the float 4. In the downward position, the spherical surface contacts and engages with the outer surface of the float 4, thereby closing one end of the drain channel 32. The aforementioned first pull rope 41 is inserted into the drain channel 32, with its first end connected to the float 4 and its second end equipped with a counterweight 43. This counterweight 43 has a designed weight, providing gravity to apply tension to the float 4, improving the stability of the float 4 during both rising and sinking.

[0033] The aforementioned top plate 13 has a disassembly window 14 corresponding to the connecting hole 21. A cover plate 15 is bolted to the disassembly window 14. The aforementioned corrugated pipe 5 is made of heat-resistant material and can expand and contract along its length. The corrugated pipe 5 is arranged in the upper space 11, and a ring is arranged at the upper end of the corrugated pipe 5. This ring is sealed and fixed to the cover plate 15 by welding or bolting. A sealing plate 51 covers the lower end of the corrugated pipe 5. The second pull rope 42 is a soft rope, which connects the sealing plate 51 and the float 4. When the corrugated pipe 5 contracts upward, the second pull rope 42 pulls the float 4 upward. A vertically extending pull rod 6 is installed on the sealing plate 51 inside the corrugated pipe 5. The pull rod 6 is movably inserted into the cover plate 15. Pulling the pull rod 6 causes the corrugated pipe 5 to expand and contract.

[0034] The use of the bellows 5 in conjunction with the above-mentioned structure can isolate the steam from the pull rod 6, prevent steam from leaking from the movable positions of the pull rod 6 and the cover plate 15, and effectively improve the overall sealing performance.

[0035] In this embodiment, a recessed structure 22 is formed on the aforementioned partition 2. The aforementioned connecting hole 21 is arranged on the recessed structure 22. Through the recessed structure 22, condensate water in the upper space 11 can be collected and flow into the connecting hole 21.

[0036] In this embodiment, the aforementioned filter plates 7 are arranged on the left and right sides of the upper space 11, and are located on both sides of the aforementioned recessed structure 22. These two filter plates 7 divide the upper space 11 into a left chamber, a middle chamber, and a right chamber. The aforementioned connecting hole 21 communicates with the middle chamber. The steam inlet 16 communicates with the left chamber, and the steam outlet 17 communicates with the right chamber. The bottom of the filter plate 7 is in contact with the partition plate 2, and notches 72 are spaced along the bottom edge of the filter plate 7. Condensate in the left and right chambers can collect in the middle chamber through the notches 72.

[0037] The casing structure 1 has flushing nozzles 8 installed on its left and right side walls, corresponding to each filter plate 7. The water outlet of each flushing nozzle 8 faces the filter plate 7, and the nozzles are connected to an external water source to flush the filter plates 7 and prevent clogging. Impurities flushed off the filter plates 7 converge into the central chamber.

[0038] In practical use, during steam transport, the condensate produced in the upper space 11 moves towards the connecting hole 21, and the float 4 floats upward in the concave cavity 31 to open the drainage channel 32. The condensate then enters the lower space 12 through the drainage channel 32. Water is sprayed through the flushing nozzle 8 to wash away fibers, sludge, and other impurities from the filter plate 7, which then collect in the connecting hole 21. By pulling the lever 6, the bellows 5 can be extended or retracted, causing the float 4 to move upward, completely moving the float 4 away from the concave cavity 31, thus allowing the accumulated water and impurities in the concave cavity 31 to be completely discharged. Through this method, the generated condensate can be automatically discharged, and the drainage capacity can be changed to facilitate the discharge of fibers, sludge, and other impurities, effectively meeting the steam transport requirements and demonstrating strong practicality.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
