Description

Technical Field

[0001] This utility model relates to the field of deaerator technology, and in particular to a water distribution plate. Background Technology

[0002] In a thermal system, the deaerator is a device that ensures the safe operation of thermal equipment. Its function is to remove oxygen and non-condensable gases from the feed water, preventing these gases from corroding the thermal equipment and affecting its service life and operating efficiency. The water distribution plate is responsible for evenly distributing the water flow. When oxygen-containing water enters the deaerator, the water distribution plate evenly disperses the water into fine droplets, allowing the water to fully contact the heating steam inside the deaerator. This process increases the contact area and contact time between the water and steam, thereby more efficiently separating dissolved gases from the water and improving the deoxygenation effect.

[0003] Traditional water distribution trays deform under long-term water flow impact and pressure, affecting the accuracy and stability of water distribution and shortening the service life of the tray. Existing technologies use crisscrossing reinforcing ribs on the lower surface of the tray body and folded edges to prevent damage to the water distribution holes from water flow erosion. However, in actual use, the water flows directly out of the holes in existing water distribution trays, which prevents the water flow from spreading evenly. Furthermore, over long-term use, the water distribution holes become clogged by impurities and particles in the water, reducing the water flow area and lowering equipment performance.

[0033] 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.

[0034] Reference Figure 2 , Figure 5 and Figure 6This utility model provides an embodiment of a water distribution plate, including a water distribution plate 1, which provides a water distribution space. Multiple water distribution holes 4 are equidistantly opened on the bottom side of the inner side of the water distribution plate 1, allowing water to be evenly discharged from the water distribution plate 1. A dispersion and anti-clogging mechanism 2 is provided inside the water distribution plate 1 to disperse the water flow and prevent impurities from clogging the water distribution holes. A sealing cover 5 is provided on the top of the water distribution plate 1 to prevent water splashing and protect the internal structure. A dispersion cylinder 6 is fixedly connected to the top of the sealing cover 5, which initially disperses the incoming water flow, making the water flow distribution more uniform. The top of the dispersing cylinder 6 is equipped with a driving mechanism 8, which provides power for dispersing the water flow. The top right side of the dispersing cylinder 6 is fixedly connected to a water inlet pipe 7, which is used to introduce water flow into the dispersing cylinder 6. The top of the water distribution plate 1 is equipped with a connecting mechanism 9, which is used to securely connect the sealing cover 5 and the dispersing cylinder 6 to ensure the integrity of the structure. The outer wall of the dispersing cylinder 6 is equipped with a sealing mechanism 10, which prevents water flow from leaking from the connection between the dispersing cylinder 6 and the sealing cover 5. The interior of the dispersing cylinder 6 is equipped with a filter mechanism 3, which filters the water flow and reduces impurities entering the water distribution holes.

[0035] The dispersion and anti-clogging mechanism 2 includes a spiral dispersion blade shaft 201. The spiral dispersion blade shaft 201 rotates on the inner wall of the dispersion cylinder 6, driving the water flow to form a spiral flow, thus achieving the function of initially dispersing the water flow. The outer wall of the spiral dispersion blade shaft 201 is rotatably connected to the inner wall of the dispersion cylinder 6. Fixing rings 202 are fixedly connected to the upper and lower sides of the inner walls of multiple water distribution holes 4. The fixing rings 202 provide an installation base for the fixed guide shafts 203, enhancing the structural stability of the water distribution holes. Multiple fixed guide shafts 203 are equidistantly fixed to the inner walls of the multiple fixing rings 202. The fixed guide shafts 203 guide the water flow direction and assist the spiral self-cleaning guide blades 206 in their operation. The inner side of 3 is fixedly connected with corresponding support rings 204. The support rings 204 provide support for the rotating shaft 205 to ensure the rotational stability of the spiral self-cleaning guide vane 206. The inner walls of multiple support rings 204 are rotatably connected with corresponding rotating shafts 205. The rotating shafts 205 enable the spiral self-cleaning guide vane 206 to rotate flexibly. The outer walls of multiple rotating shafts 205 are fixedly connected with spiral self-cleaning guide vanes 206. The spiral self-cleaning guide vanes 206 make the water flow rotate in the water distribution hole, evenly spread the water flow and scrape off impurities to prevent the water distribution hole from being blocked. The outer walls of multiple spiral self-cleaning guide vanes 206 are rotatably connected to the inner walls of the corresponding water distribution hole 4.

[0036] The drive mechanism 8 includes a mounting base 801, which fixes the drive motor 802 and the geared motor 803 and provides them with a mounting position. The bottom of the mounting base 801 is fixedly connected to the top of the dispersion cylinder 6. The drive motor 802 is fixedly connected to the top of the inner wall of the mounting base 801. The drive motor 802 provides a power source to drive the geared motor 803 to operate. The output end of the drive motor 802 is fixedly connected to the geared motor 803. The geared motor 803 adjusts the output speed of the drive motor 802 so that the rotation speed of the spiral dispersion blade shaft 201 is appropriate. The output end of the geared motor 803 is fixedly connected to the bottom end of the spiral dispersion blade shaft 201.

[0037] Specifically, in the dispersion and anti-clogging mechanism 2, the spiral dispersion blade shaft 201 rotates inside the dispersion cylinder 6, initially dispersing the water flow in a spiral manner, making the water flow more evenly distributed within the dispersion cylinder 6 and avoiding local concentration. The spiral self-cleaning guide blade 206 inside the water distribution hole 4, on the one hand, makes the water flow rotate in the water distribution hole 4, increasing the degree of turbulence and achieving more uniform diffusion, thus improving the water distribution effect. On the other hand, it scrapes off impurities from the hole wall during rotation, preventing the water distribution hole 4 from clogging and extending the service life of the water distribution plate. The sealing ring 1001 and sealing ring 1002 of the sealing mechanism 10 work together to effectively prevent water leakage and ensure efficient and stable water distribution. The filtration mechanism 3 further filters the water flow, reducing impurities entering the water distribution hole 4, thus comprehensively ensuring the reliability and stability of the water distribution function.

[0038] Reference Figure 1 , Figure 3 and Figure 4 The connecting mechanism 9 includes multiple screws 901. The screws 901 pass through the sealing cover 5 and connect to the threaded grooves 902 on the top of the water distribution plate 1, thus connecting the sealing cover 5 and the water distribution plate 1. All screws 901 are located on the top of the sealing cover 5. Threaded grooves 902 are formed around the top of the water distribution plate 1, and these grooves 902 engage with the screws 901 to ensure a secure connection. The bottom ends of all screws 901 penetrate the sealing cover 5 and are threadedly connected to the inner walls of the corresponding threaded grooves 902. Washers 903 are slidably connected to the outer walls of all screws 901. To prevent damage to the surface of the sealing cover 5 during connection, the bottoms of multiple gaskets 903 are all in contact with the top of the sealing cover 5. The sealing mechanism 10 includes a sealing ring 1001, which enhances the sealing performance at the connection between the dispersion cylinder 6 and the sealing cover 5 to prevent water leakage. The inner wall of the sealing ring 1001 is fixedly connected to the bottom side of the outer wall of the dispersion cylinder 6. A sealing ring 1002 is fixedly connected to the bottom of the sealing cover 5. The sealing ring 1002 further enhances the sealing effect to ensure that water does not leak from the bottom. The bottom of the sealing ring 1002 is in contact with the top of the water distribution plate 1.

[0039] Specifically, the drive mechanism 8, through the cooperation of the drive motor 802 and the reduction motor 803, provides stable and appropriate speed power for the dispersed water flow. The connection mechanism 9 adopts a combination of screws 901, threaded grooves 902 and gaskets 903 to firmly connect the sealing cover 5 and the dispersion cylinder 6, while protecting the sealing cover 5 from damage.

[0040] Reference Figure 1 , Figure 2 and Figure 7 The filter mechanism 3 includes a filter screen 301, which is used to intercept impurities in the water flow, reduce their entry into the water distribution holes, and ensure the water distribution effect. The outer wall of the filter screen 301 is slidably connected to the inner wall of the sealing cover 5. This sliding connection method facilitates the installation and removal of the filter screen 301. Ball sockets 302 are provided on both the front and rear sides of the filter screen 301. The ball sockets 302 provide installation positions for ball heads 303. Ball heads 303 are slidably connected to the inner walls of both ball sockets 302. The ball heads 303 slide within the ball sockets 302, cooperating with springs. 304 achieves elastic fixation of filter screen 301. Springs 304 are fixedly connected to the opposite sides of the two ball heads 303. Springs 304 provide elastic force to keep filter screen 301 stable inside the sealing cover 5 and to withstand certain impacts. Slide grooves 305 are provided on the front and rear sides of the inner wall of the sealing cover 5. Slide grooves 305 provide tracks for the sliding of springs 304. The inner walls of the two slide grooves 305 are slidably connected to the outer walls of the corresponding springs 304 to ensure that springs 304 can move along the direction of slide grooves 305 when subjected to force.

[0041] Unlocking components 306 are provided on both the front and rear sides of the sealing cover 5. The unlocking components 306 are used to quickly release the fixed state of the filter screen 301. The unlocking components 306 include two unlocking levers 3061. The unlocking levers 3061 are used to transmit pulling force and push the ball head 303 out of the ball socket 302. One end of the two unlocking levers 3061 is fixedly connected to the other side of the corresponding ball head 303 to realize the effective transmission of force. The outer wall of the two unlocking levers 3061 is slidably connected to the inner wall of the corresponding spring 304 so that the unlocking operation does not affect the elastic support of the spring 304. The two unlocking levers 3061 are rotatably connected to the opposite side of each other. The unlocking handles 3062 make it convenient for the operator to apply force and facilitate the unlocking process.

[0042] Specifically, the filter screen 301 is slidably connected to the inner wall of the sealing cover 5, which can effectively intercept water impurities, reduce their entry into the water distribution holes, and ensure smooth water distribution. The connection structure composed of the ball socket 302, the ball head 303, and the spring 304 can adapt to the impact of water flow. By pulling the unlocking handle 3062 to drive the unlocking lever 3061, the filter screen 301 can be easily unlocked and removed for cleaning and replacement, improving maintenance convenience and ensuring the long-term effectiveness of the filtration function.

[0043] Reference Figure 4 , Figure 5 and Figure 6 Multiple rotating shafts 205 are fixedly connected to water distribution hole reinforcing rings 11 at their upper and lower ends. The water distribution hole reinforcing rings 11 enhance the strength of the connection between the rotating shafts 205 and the water distribution hole related structures. One side of each water distribution hole reinforcing ring 11 is rotatably connected to the other side of the corresponding support ring 204, realizing a rotatable connection between the rotating shafts 205 and the support ring 204, ensuring that the spiral self-cleaning guide vane 206 can rotate flexibly. The top of the inner wall of each of the multiple water distribution holes 4 is fixedly connected to a limiting plate 12, which restricts the upward movement of the spiral self-cleaning guide vane 206. Within the range of the water distribution hole 4, a support ring 23 is rotatably connected to the bottom of the spiral dispersion blade shaft 201. The support ring 23 provides support for the bottom of the spiral dispersion blade shaft 201, making its rotation more stable. Support shafts 14 are fixedly connected to the outer walls of the support ring 23. The support shafts 14 connect the support ring 23 to the inner wall of the dispersion cylinder 6. The outer sides of multiple support shafts 14 are fixedly connected to the bottom side of the inner wall of the dispersion cylinder 6, stabilizing the position of the support ring 23 in the dispersion cylinder 6, thereby ensuring the stable rotation of the spiral dispersion blade shaft 201.

[0044] Specifically, the water distribution hole reinforcing ring 11 enhances the connection strength between the rotating shaft 205 and the water distribution hole, ensuring structural stability. It is rotatably connected to the support ring 1 204, ensuring the flexible rotation of the spiral self-cleaning guide vane 206. The limiting disk 12 restricts the upward movement of the vane, making the rotation more stable. The support ring 2 13 and the support shaft 14 provide reliable support for the spiral dispersion blade shaft 201, stabilizing its position in the dispersion cylinder 6 and improving the overall operational stability and reliability.

[0045] Working principle: When water flows into the dispersion cylinder 6 from the inlet pipe 7, the drive mechanism 8 activates. The drive motor 802 is mounted on the top of the inner wall of the mounting base 801, and its output end is connected to the reduction motor 803. The output end of the reduction motor 803 is fixedly connected to the bottom end of the spiral dispersion blade shaft 201. When the drive motor 802 starts, it drives the reduction motor 803 to rotate, which in turn drives the spiral dispersion blade shaft 201 to rotate on the inner wall of the dispersion cylinder 6. The rotation of the spiral dispersion blade shaft 201 performs preliminary spiral dispersion of the water flowing into the dispersion cylinder 6. This allows the water flow to be distributed more evenly within the dispersion cylinder 6, preventing water from concentrating in localized areas. After initial dispersion, the water flows downwards into the distribution hole 4. At this point, the spiral self-cleaning guide vanes 206 in the dispersion and anti-clogging mechanism 2 begin to operate. Under the impact of the water flow, the spiral self-cleaning guide vanes 206 rotate around the rotating shaft 205 within the distribution hole 4. On one hand, their spiral shape causes the water flow to rotate within the distribution hole, increasing the degree of turbulence and helping the water flow to diffuse more evenly when it exits the distribution hole, overcoming the limitations of existing distribution mechanisms. To address the issue of uneven water flow from the distribution holes in the water tray, the spiral self-cleaning guide vanes 206 scrape off impurities adhering to the inner wall of the distribution holes during rotation. The scouring force of the water flow carries these impurities out, preventing blockage. Simultaneously, the fixing rings 202 fixed to the upper and lower sides of the inner wall of the distribution hole 4, along with the fixed guide shafts 203 and inner support rings 204 equidistantly connected to the inner wall of the fixing rings 202, provide stable support and rotation conditions for the spiral self-cleaning guide vanes 206. The connecting mechanism 9 connects through multiple... Screw 901 connects the sealing cover 5 to the top of the water distribution plate 1. Gasket 903 prevents the sealing cover 5 from being damaged during the connection process, ensuring a stable connection. The sealing ring 1001 and sealing ring 1002 in the sealing mechanism 10 work together to ensure the sealing between the dispersion cylinder 6 and the water distribution plate 1, preventing water leakage. The filtration mechanism 3 further filters the water flow, reducing impurities entering the water distribution hole 4, achieving uniform water flow diffusion, avoiding the reduction of water flow area due to impurities clogging the water distribution hole, and improving the water distribution function and equipment performance.

[0046] Furthermore, when water flows into the dispersion cylinder 6 from the inlet pipe 7, it flows downwards after initial dispersion, first passing through the filter screen 301. The outer wall of the filter screen 301 is slidably connected to the inner wall of the sealing cover 5. Ball heads 303 are slidably connected to the ball sockets 302 on its front and rear sides, respectively. The ball heads 303 are connected to the sliding grooves 305 on the inner wall of the sealing cover 5 through springs 304. This structure allows the filter screen 301 to be stably engaged in the sealing cover 5. When the water flows through the filter screen 301, impurities in the water are intercepted, further reducing the amount of impurities entering the water distribution hole 4. To prevent clogging of the water distribution holes, when it is necessary to clean and replace the filter screen 301, the unlocking component 306 can be operated. By pulling the unlocking handle 3062, the unlocking lever 3061 connected to it is driven to slide through the spring 304 and push the ball head 303 out of the ball socket 302, thereby releasing the fixation of the filter screen 301. At this time, the filter screen 301 can be taken out from the sealing cover 5 for cleaning and replacement. The operation is convenient, ensuring that the filtration mechanism continues to work effectively and maintaining the good water distribution performance of the water distribution plate.
