Description

Technical Field

[0001] This application relates to the technical field of cooling equipment, and in particular to a cooling tower with a built-in water inlet pipe. Background Technology

[0002] A cooling tower is a device used to cool hot water or other fluids. Cooling towers are widely used in industrial production, air conditioning systems, power plants, and chemical industries.

[0003] In related technologies, please refer to Chinese utility model patent with authorization announcement number CN206618292U, which discloses a spray cooling tower. The tower body has a support frame at the bottom with a water outlet for inputting cooled water. The tower body is located above the tower body, and an air intake layer with louvers is located between the tower body and the support frame. An air outlet is located above the tower body, and a fan is installed inside the air outlet. A gearbox for controlling the fan speed is located below the fan. A water supply pipe is located in the center of the air outlet, and a booster pump is located below the water supply pipe to provide pressurized water to the water supply pipe. The water supply pipe passes through the tower body, extends from below the support frame to the outside of the tower body, and is connected to an external water supply end. Spray heads are arranged around the tower body. The spray heads are right-angled and have a first nozzle and a second nozzle at both ends. The middle of the spray heads is connected to the water supply pipe through a pipeline.

[0004] However, in actual operation, the water inlet pipe of the aforementioned cooling tower runs from the outside of the tower body and connects to a ring of spray pipes inside the tower body. This causes the hot water in the inlet pipe to reach the nozzles at different positions on the spray pipe at different times, and the water pressure is also different, resulting in uneven cooling effect of the cooling tower on the water. Summary of the Invention

[0005] To ensure more uniform and synchronized water intake inside the cooling tower, this application provides a cooling tower with a built-in water inlet pipe.

[0006] The cooling tower with a built-in water inlet pipe provided in this application adopts the following technical solution: A cooling tower with a built-in water inlet pipe includes a tower body and a spray pipe disposed on the tower body. The tower body is provided with a water-passing device for introducing hot water into the spray pipe. The water-passing device includes: The first water pipe is installed on the tower body, located inside the tower body, and located at the center of the cross-section of the spray pipe. The second water pipe is provided in multiple ways. The multiple second water pipes are evenly distributed on the first water pipe and are connected to both the first water pipe and the spray pipe.

[0007] By adopting the above technical solution, the first water pipe is fixed on the tower body and located at the center of the spray pipe. Then, the first water pipe is connected to the spray pipe through the second water pipe. This ensures that the water pressure and volume are the same at all points in the spray pipe after the first water pipe is filled with water, so that the spray pipe can spray hot water evenly and ensure the cooling effect of the hot water. Moreover, the structure is simple and does not require manual connection of valves or other pressure regulating devices to the spray pipe.

[0008] Optionally, the first water pipe and the second water pipe are rotatably connected together by a connecting mechanism, the connecting mechanism comprising: The first rotating plate is rotatably mounted on the first water pipe. The first rotating plate has a plurality of water outlet holes that are evenly distributed around its center and communicate with the first water pipe. A rotating ring wall is provided on a first rotating plate, and a second water pipe is provided on the rotating ring wall and communicates with the inside of the rotating ring wall. A baffle is disposed on the rotating ring wall, and the baffle is located on the side of the rotating ring wall away from the first rotating plate; The blades are arranged in multiple ways, and each blade is set on a first rotating plate. Each blade corresponds to a plurality of water outlets. The blades are inclined, with one end of the blade set on the side of the water outlet and the other end of the blade extending above the water outlet along the direction close to the water outlet. The horizontal component of the force generated by the blade after being impacted by the water flow is greater than the resistance of the water body to the first rotating plate in the water outlet.

[0009] By adopting the above technical solution, water flows out of the first water pipe through the outlet hole. After flowing out of the outlet hole, the water comes into contact with the blade. The inclined blade generates a horizontal component force after being impacted by the water flow. Since this component force is greater than the resistance of the water body to the first rotating plate in the outlet hole, the first rotating plate rotates. The rotation of the first rotating plate drives the blade to move. The movement of the blade and the baffle work together to drive the water body to move towards the rotating ring wall and into the second water pipe. The second water pipe rotates with the first rotating plate while introducing hot water into the spray pipe, making the water injection effect of each second water pipe into the spray pipe more uniform. At the same time, the fanning of the blade provides a driving force to the water body entering the second water pipe, increasing the pressure of the water body entering the second water pipe and improving the water output effect of the second water pipe.

[0010] Optionally, the spray pipe has a horizontal sliding hole, and a rotating ring is rotatably mounted on the spray pipe. The rotating ring is located inside the sliding hole, and the end of the second water pipe away from the rotating ring wall is mounted on the rotating ring and communicates with the inside of the spray pipe.

[0011] By adopting the above technical solution, a sliding hole is opened on the inner ring wall of the spray pipe, and a rotating ring is rotatably installed on the sliding hole. The second water pipe is connected to the spray pipe through the rotating ring, thereby realizing the rotatable connection between the second water pipe and the spray pipe.

[0012] Optionally, an inclined guide surface is provided on the inner wall of the water outlet of the first rotating plate.

[0013] By adopting the above technical solution, an inclined guide surface is opened on the inner side wall of the water outlet of the first rotating plate, thereby reducing the resistance of the water to the first rotating plate when the first rotating plate rotates, increasing the rotation speed of the first rotating plate, thereby increasing the water pressure in the second water pipe and improving the water output effect of the second water pipe.

[0014] Optionally, the first rotating plate is provided with a rotating shaft, the rotating shaft is in a vertical state, the top end of the rotating shaft extends vertically upward to the top of the tower body, and multiple fan blades are evenly distributed on the side wall of the rotating shaft.

[0015] During the cooling process, the hot water inside the tower will generate a large amount of water vapor, which will gradually increase the humidity inside the tower. When the humidity inside the tower is saturated, water vapor will no longer be generated, thus reducing the cooling effect.

[0016] By adopting the above technical solution, the rotation of the first rotating plate drives the rotating shaft to rotate, the rotation of the rotating shaft drives the fan blades to rotate, and the rotation of the fan blades blows the water vapor inside the tower out of the tower, thus ensuring the cooling effect of the tower. Moreover, there is no need to set up a separate power source for the fan, the structure is simple, energy-saving and environmentally friendly.

[0017] Optionally, the cooling tower is equipped with a recovery mechanism for recovering moisture from the hot steam, the recovery mechanism comprising: A recovery pipe is installed on the tower body, and a vortex channel is opened inside the recovery pipe; The return pipe has one end installed on the tower body and located above the fan blades, communicating with the inside of the tower body; the other end of the return pipe is connected to the recovery pipe and communicates with the inside of the cyclone channel. An exhaust pipe is provided on the recovery pipe and communicates with the inside of the recovery pipe.

[0018] By adopting the above technical solution, the fan rotates to discharge the hot steam inside the tower into the return gas pipe. The return gas pipe then passes the hot steam into the recovery pipe. The hot steam moves along the swirling channel in the recovery pipe. Under centrifugal force, the water in the hot steam flows down along the side wall of the swirling channel and accumulates at the bottom of the return water pipe. The gas is discharged through the outlet pipe, thus completing the work of recovering and utilizing the water in the hot steam and reducing the waste of water resources.

[0019] Optionally, the bottom of the recycling pipe is provided with a water outlet, and an installation mechanism is provided on the recycling pipe. A water collection tank is detachably connected to the recycling pipe through the installation mechanism, and the water collection tank is located below the water outlet.

[0020] By adopting the above technical solution, a water collection tank is set at the bottom of the recycling pipe. The water collected in the recycling pipe through the vortex channel is discharged from the outlet and enters the water collection tank. The water collection tank collects the water. When the water collection tank is full, it can be removed by the installation mechanism to recycle the water in the water collection tank, thereby realizing the recycling of the water collected in the recycling pipe.

[0021] Optionally, the mounting mechanism includes: Mounting plate, which is mounted on the tower body, has horizontal insertion holes on its outer side wall; An insert plate, which is disposed on the water collection tank and is inserted into the insertion hole; A limiting component is disposed on the mounting plate and is used to limit the position of the insert plate.

[0022] By adopting the above technical solution, the limiting component is unlocked, the movable insert plate is disengaged from the insertion hole, and the water collection tank can be taken out for use. The empty water collection tank is moved so that the insert plate is inserted into the mounting plate, and then the limiting component is locked, thus completing the installation of the water collection tank.

[0023] Optionally, the limiting component includes: The limiting block has a vertical sliding groove on the inner side wall of the insertion hole, and the limiting block is slidably disposed on the sliding groove; A limiting spring is provided on the bottom wall of the sliding groove and connected to the limiting block. The insert plate is provided with a limiting groove corresponding to the sliding groove. Under the action of the limiting spring, the limiting block extends out of the sliding groove and is inserted into the limiting groove. A pull rod is slidably mounted on the mounting plate, with one end of the pull rod located outside the mounting plate and the other end of the pull rod extending into the sliding groove and connecting to the limiting block.

[0024] By adopting the above technical solution, pulling the lever causes the limiting block to move. The limiting block squeezes the limiting spring and disengages from the limiting groove, moving into the sliding groove. This releases the limiting block from restricting the insertion plate, allowing the insertion plate to be moved out of the insertion hole. When the insertion plate is inserted into the insertion hole, the lever is released. Under the action of the limiting spring, the limiting block extends out of the sliding groove and engages with the limiting groove, thus limiting the insertion plate within the insertion hole.

[0025] Optionally, the bottom of the water collection tank is equipped with four casters.

[0026] By adopting the above technical solution, four omnidirectional wheels are installed at the bottom of the water collection tank, which makes it easier for staff to move the water collection tank, reduces the workload when moving the water collection tank, and improves work efficiency.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. By fixing the first water pipe to the tower body and placing it at the center of the spray pipe, and then connecting the first water pipe to the spray pipe through the second water pipe, the water pressure and volume entering the spray pipe after the first water pipe is filled are the same, so that the spray pipe can spray hot water evenly and ensure the cooling effect of the hot water. 2. By opening a sliding hole in the inner ring wall of the spray pipe, and rotating and installing a rotating ring in the sliding hole, the second water pipe is connected to the spray pipe through the rotating ring, thereby realizing the rotating connection between the second water pipe and the spray pipe; 3. By pulling the lever, the limiting block moves, causing the limiting block to squeeze the limiting spring and disengage from the limiting groove and move into the sliding groove. This releases the limiting block from restricting the insertion plate, allowing the insertion plate to be moved out of the insertion hole. When the insertion plate is inserted into the insertion hole, the lever is released, and the limiting block, under the action of the limiting spring, extends out of the sliding groove and engages with the limiting groove, thus limiting the insertion plate within the insertion hole.

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail.

[0031] This application discloses a cooling tower with a built-in water inlet pipe.

[0032] Reference Figure 1 The cooling tower with a built-in water inlet pipe includes a tower body 1.

[0033] Reference Figure 2 and Figure 3 A spray pipe 11 is coiled and fixedly connected inside the tower body 1. A water supply device 2 is provided on the tower body 1 for introducing hot water into the spray pipe 11.

[0034] Reference Figure 2 and Figure 3 The water supply device 2 includes a first water supply pipe 21 and a second water supply pipe 22. The first water supply pipe 21 is fixedly connected to the tower body 1 and located inside the tower body 1. The first water supply pipe 21 is vertical and located at the center of the cross-section of the spray pipe 11. The second water supply pipe 22 is rotatably connected to the first water supply pipe 21 by a connecting mechanism 3.

[0035] Reference Figure 3 and Figure 4 The connecting mechanism 3 includes a first rotating plate 31, a rotating ring wall 32, a baffle 33, and blades 34. The first rotating plate 31 is rotatably mounted on the top of the first water pipe 21. Multiple water outlet holes 35, communicating vertically with the first water pipe 21, are evenly distributed axially around the center of the first rotating plate 31. Inclined guide surfaces 36 are formed on the inner walls of the water outlet holes 35. Multiple blades 34 are fixedly connected to the upper surface of the first rotating plate 31. One end of each blade 34 is fixedly connected to the side of a water outlet hole 35, and the other end extends above the water outlet hole 35 along a direction close to it. One blade 34 corresponds to one water outlet hole 35.

[0036] Reference Figure 3 and Figure 4 A rotating ring wall 32 is fixedly connected to the upper surface of the first rotating plate 31, and a baffle 33 is fixedly connected to the upper surface of the rotating ring wall 32. Multiple second water pipes 22 are provided, evenly distributed and fixedly connected to the outer wall of the rotating ring wall 32 and communicating with the interior of the rotating ring wall 32. A horizontal sliding hole is opened on the side of the spray pipe 11 closest to the rotating ring wall 32, and a rotating ring 37 is rotatably mounted on the spray pipe 11, located within the sliding hole. The end of the second water pipe 22 away from the rotating ring wall 32 is fixedly connected to the outer wall of the rotating ring 37 and communicates with the interior of the spray pipe 11.

[0037] Reference Figure 3 and Figure 4Water flows out of the first water pipe 21 through the outlet 35. After flowing out of the outlet 35, the water comes into contact with the blade 34. The inclined blade 34 generates a horizontal component force after being impacted by the water flow. Since this component force is greater than the resistance of the water body to the first rotating plate 31 in the outlet 35, the first rotating plate 31 rotates. The rotation of the first rotating plate 31 drives the blade 34 to move. The movement of the blade 34 and the baffle 33 work together to drive the water body to move towards the rotating ring wall 32 and into the second water pipe 22. The second water pipe 22 rotates with the first rotating plate 31 while introducing hot water into the spray pipe 11, making the water injection effect of each second water pipe 22 into the spray pipe 11 more uniform. At the same time, the fanning of the blade 34 provides a driving force to the water body entering the second water pipe 22, increasing the pressure of the water body entering the second water pipe 22 and improving the water output effect of the second water pipe 22.

[0038] Reference Figure 3 and Figure 4 A rotating shaft 38 is fixedly connected to the upper surface of the first rotating plate 31. The rotating shaft 38 is vertical, and its top end extends vertically upward through the baffle 33 to the upper opening of the tower body 1. Multiple fan blades 39 are evenly distributed and fixed on the outer wall of the rotating shaft 38. The rotation of the first rotating plate 31 drives the rotating shaft 38 to rotate, which in turn drives the fan blades 39 to rotate, thus fanning the water vapor inside the tower body 1 out of the tower body 1.

[0039] Reference Figure 3 and Figure 4 The tower body 1 is equipped with a recovery mechanism 4 for recovering moisture from hot steam. The recovery mechanism 4 includes a recovery pipe 41, a return pipe 42, and an outlet pipe 43. The recovery pipe 41 is fixedly connected to the outer wall of the tower body 1. One end of the return pipe 42 is fixedly connected to the upper surface of the tower body 1 and communicates with an opening on the upper surface of the tower body 1. The other end of the return pipe 42 is connected to the recovery pipe 41 and communicates with the interior of the recovery pipe 41. A swirl channel 44 is opened inside the recovery pipe 41. After the hot steam enters the recovery pipe 41 through the return pipe 42, it moves along the swirl channel 44. The moisture in the hot steam is separated from the hot steam under centrifugal force and flows down along the side wall of the swirl channel 44.

[0040] Reference Figure 3 and Figure 4 An exhaust pipe 43 is fixedly connected to the top of the recovery pipe 41 and located on the side away from the return pipe 42. The exhaust pipe 43 communicates internally with the recovery pipe 41, and the gas after moisture separation is discharged from the exhaust pipe 43 into the recovery pipe 41. A water outlet 35 is provided at the bottom of the recovery pipe 41. A water collection tank 45 is detachably installed at the bottom of the recovery pipe 41 via an installation mechanism 5. The water collection tank 45 is located below the water outlet 35, and four universal wheels 46 are evenly distributed and rotatably connected to its lower surface. The water collection tank 45 collects the water flowing out of the water outlet 35.

[0041] Reference Figure 3 and Figure 4 The installation mechanism 5 includes an installation plate 51, an insert plate 52, and a limiting component 53. The installation plate 51 is fixedly connected to the outer wall of the recovery pipe 41. A horizontal insertion hole is provided on the side wall of the installation plate 51 away from the recovery pipe 41. The insert plate 52 is fixedly connected to the water collection tank 45 and is inserted into the insertion hole.

[0042] Reference Figure 3 and Figure 4 A limiting component 53 is mounted on the mounting plate 51 and is used to limit the position of the insert plate 52. The limiting component 53 includes a limiting block 54, a limiting spring 55, and a pull rod 56. A vertical sliding groove 57 is provided on the inner wall of the insertion hole, and the limiting block 54 is slidably mounted on the sliding groove 57. The limiting spring 55 is fixedly connected to the bottom wall of the sliding groove 57 and is fixedly connected to the limiting block 54. The pull rod 56 is vertically slidably mounted on the mounting plate 51, with one end of the pull rod 56 located outside the mounting plate 51 and the other end of the pull rod 56 extending into the sliding groove 57 and fixedly connected to the limiting block 54. When the insert plate 52 is inserted into the insertion hole, a limiting groove corresponding to the opening of the sliding groove 57 is provided on the insert plate 52. Under the action of the limiting spring 55, the limiting block 54 partially extends out of the sliding groove 57 and inserts into the limiting groove.

[0043] The working principle of this application embodiment is as follows: The first water pipe 21 is fixed on the tower body 1 and located at the center of the spray pipe 11. Then, the first water pipe 21 is connected to the spray pipe 11 through the second water pipe 22. This ensures that the water pressure and volume are the same at all points in the spray pipe 11 after water is supplied through the first water pipe 21, so that the spray pipe 11 can spray hot water evenly and ensure the cooling effect of the hot water. Moreover, the structure is simple and does not require manual connection of valves or other pressure regulating devices to the spray pipe 11.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
