Description

Technical Field

[0001] This application relates to the field of steam flow channels, and more particularly to a steam flow channel structure. Background Technology

[0002] Steam forming molds or steam heating plates have steam channels opened on them to allow steam to flow and thus heat the steam. The main purpose of steam heating is to make full use of the heat of the steam.

[0003] Existing steam channels are usually smooth, with steam flowing in from one end and out from the other. Throughout the process, the steam goes straight in and out, resulting in low utilization of the steam's heat. Utility Model Content

[0004] In order to improve the utilization rate of steam heat in steam heating, this application provides a steam flow channel structure.

[0005] The steam flow channel structure provided in this application adopts the following technical solution:

[0006] A steam flow channel structure includes an upper flow channel, a lower flow channel, and a flow buffer plate, wherein the upper flow channel and the lower flow channel are disposed opposite to each other; the flow buffer plate is obliquely connected to the surface of the upper flow channel facing the lower flow channel; multiple flow buffer plates are provided, and the multiple flow buffer plates are arranged at intervals along the length direction of the upper flow channel.

[0007] By adopting the above technical solution, after steam is introduced into the flow channel, when the steam reaches the flow plate during its flow along the flow channel, it is split at the flow plate. Part of the steam gathers between the inclined flow plate and the upper flow channel, while the other part continues to flow along the flow channel, thereby prolonging the residence time of the steam in the flow channel and improving the heat utilization rate of the steam.

[0008] Optionally, the flow-damping plate is arc-shaped, with its concave surface facing the upper flow channel.

[0009] By adopting the above technical solution, a larger storage space can be formed between the flow buffer plate and the upper flow channel, so that more steam can stay in the storage space, further extending the residence time of the steam and improving the utilization rate of steam heat.

[0010] Optionally, the flow-damping plate has ventilation holes through it.

[0011] By adopting the above technical solution, when the steam flow rate is too high or too much steam accumulates between the buffer plate and the upper flow channel, some of this steam can continue to flow through the vent, reducing the pressure at the connection point between the buffer plate and the upper flow channel.

[0012] Optionally, a movable plate is hinged to the surface of the flow-retarding plate away from the upper flow channel, and the connection point between the movable plate and the flow-retarding plate is located above the vent.

[0013] By adopting the above technical solution, under normal steam flow rate, the movable plate remains stationary relative to the slow-flow plate, while when the steam flow rate is too high, the movable plate rotates relative to the slow-flow plate under the pressure of the steam, allowing the steam to flow out from the vent.

[0014] Optionally, the edge of the movable plate is magnetically connected to the edge of the vent hole.

[0015] By adopting the above technical solution, the movable plate is attached to the flow buffer plate under normal conditions. Even if the vent is closed, the movable plate will only rotate relative to the flow buffer plate under the action of steam pressure when the steam flow rate is too high or too much steam accumulates between the flow buffer plate and the upper flow channel. This ensures that the steam has sufficient residence time between the flow buffer plate and the upper flow channel.

[0016] Optionally, it also includes a water-receiving section, wherein the lower flow channel is located between the upper flow channel and the water-receiving section; the lower flow channel is provided with a plurality of water passage holes.

[0017] By adopting the above technical solution, the residence time of steam in the flow channel is extended. If the steam liquefies in the flow channel, it can fall through the water passage to the water receiving part for collection, and then the liquid can be discharged.

[0018] Optionally, the flow-damping plate is hinged to the upper flow channel.

[0019] By adopting the above technical solution, the tilt angle of the flow buffer plate relative to the upper flow channel can be adjusted, thereby improving the flexibility of the flow channel structure.

[0020] Optionally, the flow-damping plate is connected to a pull rope, which extends along the length of the upper flow channel; multiple flow-damping plates are fixedly connected to the pull rope.

[0021] By adopting the above technical solution, when adjusting the tilt angle of the flow deflector, pulling the end of the pull rope will cause all the flow deflectors to rotate together, thus improving the ease of operation for adjusting the angle of the flow deflector.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By setting multiple flow-slowing plates in the upper flow channel, and arranging the multiple flow-slowing plates at intervals along the length of the upper flow channel, the steam is diverted after encountering the flow-slowing plates during the steam flow channel. One part continues to flow along the steam flow channel, while the other part gathers between the flow-slowing plates and the upper flow channel, thereby extending the residence time of the steam in the flow channel and improving the heat utilization rate of the steam.

[0024] 2. By making the flow plate arc-shaped and with the concave surface of the flow plate facing the upper flow channel, the storage space between the flow plate and the upper flow channel that can be used to accommodate steam is increased, thereby further extending the residence time of steam in the flow channel;

[0025] 3. By setting a water-receiving part below the lower flow channel and opening a water passage in the lower flow channel, if the steam liquefies in the flow channel after extending the residence time, the liquefied liquid will fall from the water passage into the water-receiving part for collection.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a steam flow channel structure.

[0033] Example 1

[0034] Reference Figure 1 A steam flow channel structure includes an upper flow channel 1, a lower flow channel 2, a flow buffer 3, and a water receiving section 4.

[0035] The upper flow channel 1 and the lower flow channel 2 are arranged opposite to each other. The surface of the upper flow channel 1 can be flat or curved, and the surface of the lower flow channel 2 can be flat or curved.

[0036] A flow-damping plate 3 is inclinedly connected to the surface of the upper flow channel 1 facing the lower flow channel 2. Multiple flow-damping plates 3 are provided, arranged at intervals along the length of the upper flow channel 1. After steam is introduced into the flow channel, as the steam flows along the flow channel, it reaches the flow-damping plate 3 and is split at the flow-damping plate 3. Part of the steam accumulates between the inclined flow-damping plate 3 and the upper flow channel 1, while the other part continues to flow along the flow channel, thereby prolonging the residence time of the steam in the flow channel and improving the heat utilization rate of the steam.

[0037] The water-receiving section 4 is located below the lower flow channel section 2, and there is a gap between the water-receiving section 4 and the lower flow channel section 2. The lower flow channel section 2 has several water passage holes 22 that are arranged at intervals along the length of the lower flow channel section 2. If the steam liquefies in the flow channel pipe after the residence time of the steam is extended, it can fall into the water-receiving section 4 through the water passage holes 22 for collection.

[0038] Reference Figure 2 Furthermore, a guide groove 21 is provided on the surface of the lower flow channel 2 facing the upper flow channel 1. The guide groove 21 extends along the length of the lower flow channel 2 so that the steam can pass through the water passage 22 more smoothly after liquefaction.

[0039] In this embodiment, the flow buffer 3 is arranged in an arc shape, with the concave surface of the flow buffer 3 facing the upper flow channel 1, thereby forming a larger storage space between the flow buffer 3 and the upper flow channel 1, so that more steam can stay in the storage space, further extending the residence time of the steam and improving the heat utilization rate of the steam.

[0040] In this embodiment, the edge of the flow-retardant plate 3 near the lower flow channel 2 is located directly above the water passage 22, and multiple flow-retardant plates 3 correspond one-to-one with multiple water passage 22. This allows the water formed by the liquefaction of steam on the flow-retardant plate 3 to fall directly from above the water passage 22 under the guiding effect of the inclined flow-retardant plate 3.

[0041] In other embodiments, the flow buffer 3 and the water passage 22 may be arranged in other ways.

[0042] The implementation principle of Example 1 is as follows: When using steam for heating, steam is introduced into the steam channel. During the flow of the steam along the channel, it is diverted by the flow-slowing plate 3. Part of the steam continues to flow along the channel, while the other part temporarily stays in the space between the flow-slowing plate 3 and the upper channel 1, thereby prolonging the residence time of the steam in the steam channel and improving the heat utilization rate of the steam.

[0043] Example 2

[0044] Reference Figure 3The difference between this embodiment and embodiment 1 is that the flow plate 3 is provided with a vent 31 to prevent a large amount of steam from accumulating between the flow plate 3 and the upper flow channel 1 when the steam flow rate is high, thus avoiding a large impact on the flow plate 3.

[0045] In this embodiment, a movable plate 32 is hinged to the surface of the flow-retarding plate 3 away from the upper flow channel 1, and the connection point between the movable plate 32 and the flow-retarding plate 3 is located above the vent 31. Under normal steam flow rate, the movable plate 32 is stationary relative to the flow-retarding plate 3, but when the steam flow rate is too high, the movable plate 32 rotates relative to the flow-retarding plate 3 under the pressure of the steam, allowing steam to flow out from the vent 31.

[0046] Furthermore, in this embodiment, the edge of the movable plate 32 is magnetically connected to the edge of the vent, so as to avoid the formation of a gap between the movable plate 32 and the vent 3 under its own weight when the vent 3 is arc-shaped.

[0047] It is understandable that the surface of the movable plate 32 facing the flow control plate 3 is in contact with the surface of the flow control plate 3 facing the movable plate 32.

[0048] The implementation principle of Example 2 is as follows: After the steam enters the flow channel, it flows along the steam flow channel. A portion of the steam accumulates in the storage space formed between the slow flow plate 3 and the upper flow channel 1. When the steam flow rate is too high or too much steam accumulates in the storage space, the steam applies pressure to the movable plate 32, causing the movable plate 32 to rotate away from the slow flow plate 3, so that the steam can pass through the vent 31, reducing the pressure at the connection between the slow flow plate 3 and the upper flow channel 1.

[0049] Example 3

[0050] Reference Figure 4 The difference between this embodiment and embodiment 1 is that multiple flow buffers 3 are all hinged to the upper flow channel 1.

[0051] The flow-damping plate 3 is equipped with a pull rope 33, which extends along the length of the upper flow channel 1. Multiple flow-damping plates 3 are fixedly connected to the pull rope 33, and the two ends of the pull rope 33 extend out of the two ends of the flow channel. This design allows the tilt angle of the flow-damping plate 3 relative to the upper flow channel 1 to be adjusted, improving the flexibility of the flow channel structure. In this embodiment, the angle of the flow-damping plate 3 is adjusted by pulling the pull rope 33 from both ends.

[0052] The connection between the flow-regulating plate 3 and the pull rope 33 is as follows: the flow-regulating plate 3 has a through hole 34 for the pull rope 33 to pass through. On both sides of the flow-regulating plate 3, the pull rope 33 is connected to a positioning bead 35, with two positioning beads 35 corresponding to one flow-regulating plate 3. When connecting the pull rope 33 and the flow-regulating plate 3, first, a positioning bead 35 is passed through the pull rope 33. Then, the pull rope 33 is passed through the through hole 34 of the first flow-regulating plate 3, and the pull rope 33 is pulled until the positioning bead 35 and the flow-regulating plate 3 abut against each other. Then, another positioning bead 35 is passed through the pull rope 33 so that the positioning bead 35 abuts against the flow-regulating plate 3. The above process is then repeated.

[0053] The implementation principle of Example 3 is as follows: according to the steam flow rate and the desired effect of slowing down the steam flow rate, pull the pulling rope 33 to adjust the angle of the flow slowing plate 3 relative to the upper flow channel 1.

[0054] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
