Description

Technical Field

[0001] This utility model relates to the field of continuous sewage expansion container technology, specifically a steam-water separation device for a continuous sewage expansion container. Background Technology

[0002] A continuous blowdown expansion tank, also known as a continuous blowdown expander, is connected to the continuous blowdown port of a boiler and is used to reduce pressure and expand the capacity of the boiler's continuous blowdown.

[0003] Boiler wastewater is continuously and evenly fed into the blowdown expansion tank. The wastewater moves tangentially in the cylindrical baffle in the middle of the shell and is immediately vaporized into secondary steam. After steam-water separation by the upper louvered steam-water separator, it is introduced into the deaerator through the outlet at the top of the continuous discharge tank. The remaining wastewater is discharged through the water level regulating valve.

[0004] Louvered steam-water separators separate steam into water. However, in typical louvered steam-water separators, the separation plates are welded to the shell, which means that when the separation plates are deformed or damaged, the entire shell needs to be replaced, which is a waste of resources.

[0005] In view of this, we propose a continuous discharge expansion tank steam-water separation device. Utility Model Content

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Example 1, please refer to Figures 1 to 3 , Figure 5 and Figure 6 This utility model provides an embodiment of a continuous sewage expansion container steam-water separation device, comprising a shell 100, separation plates 200, connecting frames 300, and a fixing structure 400; the separation element composed of the separation plates 200 and the connecting frames 300 is disposed within the shell 100; wherein, multiple separation plates 200 are arranged sequentially, the separation plates 200 are wavy, and the upper and lower ends of the separation section formed by the multiple separation plates 200 are respectively provided with connecting frames 300; a fixing frame 102 is fixedly disposed at the bottom of the inner cavity of the shell 100, the fixing frame 102 is supported and cooperates with the connecting frames 300 at the bottom of the separation plates 200, the fixing frame 102 is used to support the separation plates 200 and the connecting frames 300 placed inside the shell 100, and facilitates the subsequent fixing structure 400 to fix the separation element composed of the separation plates 200 and the connecting frames 300; the fixing structure 400 is disposed at the side end of the shell 100;

[0041] The fixed structure 400 includes a screw 401, a handle 402, and a U-shaped plate 403. The inner end of the screw 401 is rotatably connected to the side end of the housing 100 via a rotating shaft. The handle 402 is fixed to the outer end of the screw 401. The longitudinal section of the U-shaped plate 403 is threaded onto the screw 401. The two transverse sections of the U-shaped plate 403 are respectively fitted through the through holes 101 opened on the side end of the housing 100, and the two transverse ends of the U-shaped plate 403 are respectively fitted with the opposite side of the two connecting frames 300. A guide rod 404 is fixed to the side end of the housing 100. The guide rod 404 passes through the longitudinal section of the U-shaped plate 403, and the U-shaped plate 403 moves along the guide rod 404, so that the movement of the U-shaped plate 403 remains stable.

[0042] When the separating plate 200 and the connecting frame 300 are installed inside the housing 100, the operator rotates the handle 402, causing the screw 401 to rotate accordingly. The U-shaped plate 403 moves along the screw 401 toward the housing 100 until the two lateral ends of the U-shaped plate 403 contact the opposite sides of the two connecting frames 300, thus fixing the separating component consisting of the separating plate 200 and the connecting frame 300 inside the housing 100. When disassembling the damaged or deformed separating plate 200, the handle 402 is rotated in the opposite direction, causing the screw 401 to rotate in the opposite direction. The U-shaped plate 403 moves along the screw 401 away from the housing 100 until the two lateral ends of the U-shaped plate 403 no longer contact the opposite sides of the two connecting frames 300, and the separating component consisting of the separating plate 200 and the connecting frame 300 is then removed from the housing 100.

[0043] This utility model, by setting up a separation plate 200, a connecting frame 300, a screw 401, a rotating handle 402, and a U-shaped plate 403, has the advantage that the separation component consisting of the separation plate 200 and the connecting frame 300 can be detached from the housing 100, while retaining the housing 100. It solves the problem that it is wasteful to replace the entire housing 100 when the separation plate 200 is deformed or damaged.

[0044] Example 2, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 One embodiment of this utility model is a continuous sewage expansion container steam-water separation device, wherein a limiting structure 500 is provided on the side end of the shell 100, and the limiting structure 500 includes a tube 501, a rod 502 and a collar 503.

[0045] The insertion tube 501 is fixed to the side end of the housing 100; the bottom of the insertion rod 502 is inserted into the insertion tube 501; the collar 503 is sleeved on the insertion rod 502; a spring 504 is connected between the collar 503 and the housing 100, and the two ends of the spring 504 are fixedly connected to the collar 503 and the housing 100 respectively. The elastic coefficient of the spring 504 shall be selected and used by the technical personnel in this field according to the actual situation; the top of the insertion rod 502 is inserted into the insertion hole 4021 opened on the outer periphery of the rotating handle 402. A stop block 405 is fixed on the inner side of the longitudinal section of the U-shaped plate 403, and the stop block 405 is limited and engaged with the side end of the housing 100.

[0046] When fixing the separating component consisting of the separating plate 200 and the connecting frame 300, the operator moves the insert rod 502 down, compresses the spring 504 until the abutment 405 contacts the side end of the housing 100, and the two lateral ends of the U-shaped plate 403 contact and limit the two connecting frames 300 on opposite sides respectively. At this time, the insertion hole 4021 corresponds to the top of the insert rod 502. The insert rod 502 is released, and under the action of the spring 504, the insert rod 502 springs up, and the top of the insert rod 502 is inserted into the insertion hole 4021, fixing the handle 402, thereby fixing the U-shaped plate 403, so that the U-shaped plate 403 stably limits the separation component consisting of the separating plate 200 and the connecting frame 300.

[0047] This utility model, by setting up an insertion tube 501, an insertion rod 502, a collar 503, a spring 504 and an insertion hole 4021, has the advantage of fixing the U-shaped plate 403 while fixing the handle 402, so that the U-shaped plate 403 can stably limit the separation of the separating piece composed of the separating plate 200 and the connecting frame 300.

[0048] Working principle: The separating plate 200 and the connecting frame 300 are installed in the inner cavity of the housing 100. The fixing frame 102 is supported by the connecting frame 300 at the bottom of the separating plate 200. The operator moves the insertion rod 502 down, the spring 504 is compressed, and the operator rotates the handle 402. The screw 401 rotates accordingly, and the U-shaped plate 403 moves along the screw 401 toward the housing 100 until the abutment 405 contacts the side of the housing 100. The two lateral ends of the U-shaped plate 403 contact and limit the two connecting frames 300 on opposite sides. At this time, the insertion hole 4021 corresponds to the top of the insertion rod 502. The insertion rod 502 is released, and under the action of the spring 504, the insertion rod 502 springs up and the top of the insertion rod 502 is inserted into the insertion hole 4021, fixing the handle 402, thereby fixing the U-shaped plate 403, and fixing the separating component composed of the separating plate 200 and the connecting frame 300 in the housing 100.

[0049] When disassembling the damaged and deformed separator 200, the worker moves the insert rod 502 down and rotates the handle 402 in the opposite direction. The screw 401 rotates in the opposite direction, and the U-shaped plate 403 moves away from the housing 100 along the screw 401 until the two lateral ends of the U-shaped plate 403 are no longer in contact with the opposite sides of the two connecting frames 300. The separator consisting of the separator 200 and the connecting frame 300 is then removed from the housing 100.
