Description

Technical Field

[0001] This application relates to the technical field of cooling equipment, and in particular to a cooling tower. Background Technology

[0002] A cooling tower is a device that allows cooling water carrying waste heat to exchange heat with air inside the tower, so that the waste heat is transferred to the air and dissipated into the atmosphere.

[0003] The cooling tower in the related technology includes a tower body with an inlet pipe extending into it. The tower body contains a cooling packing layer, a fan is installed at the top, and a water collection tank is located at the bottom, with an outlet at the tank. In use, hot water enters from the top of the tower through the inlet pipe, passes through the cooling packing layer, and the fan draws air from the side of the tower into the cooling packing layer, cooling the hot water. The cooled water then passes through the packing layer and enters the water collection tank for collection. A water pump then draws the cooled water out from the outlet for circulation.

[0004] Because the cooling tower environment is humid, algae easily grow in the water collection pool. Therefore, chemical agents such as bactericides and algaecides are often added to the cooling tower during use to reduce algae growth. However, chemical agents usually have a certain degree of toxicity, which can easily cause water pollution and thus pollute the environment. Summary of the Invention

[0005] In order to reduce environmental pollution during algae removal, this application provides a cooling tower.

[0006] This application provides a cooling tower, which adopts the following technical solution:

[0007] A cooling tower includes a tower body, an inlet pipe, and a water collection tank. The inlet pipe is connected to the tower body and extends into the tower body. The water collection tank is formed inside the tower body and has an outlet. An electronic water processor is connected to the inlet pipe. Each end of the water collection tank has an algae collection tank. A connecting port between the water collection tank and the algae collection tank is provided. A gate valve that moves to open and close the connecting port is located in the algae collection tank. An agitating device that moves towards or away from the algae collection tank is also present in the water collection tank. The agitating device includes...

[0008] A baffle, movable within the water collection tank, has a first filter screen for blocking algae;

[0009] A stirring component, connected to one side of the baffle, is used to stir and scrape away algae at the bottom of the water collection tank;

[0010] The connecting seat has one end rotating on the baffle and the other end connected to the agitator;

[0011] A rotation source, connected to the baffle, is used to drive the connecting seat to rotate, thereby causing the agitator to flip between the opposite sides of the baffle.

[0012] By adopting the above technical solution, the water entering the cooling tower is sterilized and algae-killed by an electronic water processor, which reduces the possibility of algae growth by physical means. The algae in the water collection tank are agitated and cleaned by an agitator, and the cleaned algae are guided by baffles to the algae collection tank for collection, so as to facilitate the cleaning of algae. In this way, the growing algae are cleaned by mechanical means, which can reduce environmental pollution during algae removal.

[0013] Optionally, the agitator includes a connecting shaft and blades, the connecting shaft is connected to the connecting seat, and multiple blades are distributed circumferentially along the connecting shaft, with the blades facing the water collection tank.

[0014] By adopting the above technical solution, when the agitator moves in the water collection tank, the blades can scrape and clean the algae in the water collection tank.

[0015] Optionally, the connecting shaft rotates on the connecting seat, and the inner wall of the water collection tank is provided with a first guide rail in the direction of movement of the baffle. The first guide rail is used for the outer wall of the end of the connecting shaft to abut against. The baffle is connected with a second guide rail for the outer wall of the end of the connecting shaft to abut against. The second guide rail extends along the rotation path of the connecting seat away from the baffle.

[0016] By adopting the above technical solution, the first guide rail and the second guide rail guide the movement direction of the connecting shaft. Through the friction between the first guide rail and the connecting shaft, and the friction between the second guide rail and the connecting shaft, the connecting shaft rotates simultaneously as it moves, thereby driving the blades to rotate to scrape off algae. At the same time, the water collection tank is agitated, which can stir up the water in the water collection tank, increase the contact area between the water flow and the air, and further cool the water in the water collection tank.

[0017] Optionally, the surfaces of the first and second guide rails used for abutting the connecting shaft are rough surfaces.

[0018] By adopting the above technical solution, the rough surface can increase the friction between the first guide rail and the connecting shaft, as well as between the second guide rail and the connecting shaft, further driving the connecting shaft to rotate when it is engaged with the first and second guide rails.

[0019] Optionally, the baffle is slidably sleeved on the outer wall of the first guide rail.

[0020] By adopting the above technical solution, the cooperation between the baffle and the first guide rail can guide the movement of the baffle.

[0021] Optionally, the gate plate moves up and down at the communication port, and the gate plate has a portion extending out of the algae collection tank. The portion of the gate plate located outside the algae collection tank is provided with a guide portion. When the gate plate gradually approaches the algae collection tank, the guide portion is lifted by the second guide rail, so that the gate plate moves upward to open the communication port.

[0022] By adopting the above technical solution, as the baffle approaches the gate, the guide part is lifted by the cooperation of the guide part and the second guide rail, so that the gate opens the connection port. This allows the connection port to open before the baffle reaches the gate, making it easier to guide the algae blocked by the baffle into the algae collection pond.

[0023] Optionally, a filter basket is movable up and down inside the gate. The top of the filter basket and the side facing the gate are open, and the filter basket wall has filter holes for blocking algae. A linkage is provided between the filter basket and the gate. When the gate closes the connection, the linkage moves the filter basket upward out of the algae collection tank. When the gate opens the connection, the linkage moves the filter basket downward to the bottom of the algae collection tank.

[0024] By adopting the above technical solution, the filter basket can remove algae from the water surface when the gate closes the connection port, which can improve the convenience of removing algae from the algae collection pond.

[0025] Optionally, the linkage includes,

[0026] The first toothed rack is connected to the outer wall of the filter basket;

[0027] The second rack is connected to the side of the gate facing the filter basket, and its length extension direction is parallel to the length extension direction of the first rack.

[0028] The gear is rotatably connected to the inner wall of the algae collection pool and meshes with the first rack and the second rack.

[0029] By adopting the above technical solution, the first rack and the second rack mesh with the gear simultaneously, so that when the gear rotates, the first rack and the second rack move in opposite directions, thereby causing the gate and the filter basket to move in opposite directions.

[0030] Optionally, a base is connected to the outside of the water collection tank, and a screw is rotatably connected to the base. The screw extends along the length of the water collection tank, and one end of the base has a power source to drive the screw to rotate. The baffle has a movable seat threaded onto the outer wall of the screw.

[0031] By adopting the above technical solution, the screw is driven to rotate by the power source, causing the moving seat to move along the screw axis, thereby driving the baffle to move along the length of the water collection pool.

[0032] Optionally, the outlet is located at the bottom of the water collection tank, and the water collection tank has a second filter screen for blocking algae at one end of the outlet near the inside of the water collection tank.

[0033] By adopting the above technical solution, the second filter screen can prevent algae from being moved out of the water collection tank along with the cooling water when the cooling water flows out of the outlet.

[0034] In summary, this application has the following beneficial effects:

[0035] The water entering the tower is sterilized and algae-killed by an electronic water processor, which reduces algae growth physically. Algae in the collection tank is scraped off by an agitator and moved to an algae collection pool for mechanical cleaning, thus reducing environmental pollution during algae removal.

[0043] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0044] This application discloses a cooling tower. (Refer to...) Figure 1 and Figure 2 The cooling tower includes a tower body 1, an inlet pipe 2, a water collection tank 3, a cooling packing layer 21, and a fan 22. The tower body 1 is hollow inside, and there are ventilation openings on opposite sides of the tower body 1 that connect to the interior of the tower body 1. There are two sets of cooling packing layers 21, which are installed on opposite sides of the tower body 1, respectively, opposite to the ventilation openings on both sides of the tower body 1. The inlet pipe 2 is connected to the outer wall of the tower body 1. One end of the inlet pipe 2 connects to the interior of the plant, and the other end of the inlet pipe 2 extends from the top of the tower body 1 into the interior of the tower body 1, opposite to the top of the cooling packing layer 21.

[0045] The cooling packing layer 21 has a platform 23 at its bottom, and a water collection space is provided between the two cooling packing layers 21. A water collection pool 3 is located on the platform 23 relative to the water collection space, and the water collection pool 3 is square in shape. The fan 22 is installed on the top of the tower body 1 and is opposite to the water collection pool 3. A water outlet 4 is provided on the bottom wall of the water collection pool 3. The water outlet 4 is connected to a water outlet pipe, which is connected to a water pump to pump water out of the water collection pool 3.

[0046] When the cooling tower is started, the inlet pipe 2 draws hot wastewater from the factory into the tower body 1 and scatters it onto the cooling packing layer 21. The fan 22 turns on and draws air from outside the tower body 1 into the tower body 1 through the ventilation port and the cooling packing layer 21. The air inside the tower body 1 moves toward the fan 22 and is discharged from the top of the tower, so that the hot air in the hot wastewater passing through the cooling packing layer 21 is carried away by the air to cool it and form cooling water. The cooling water falls from the cooling packing layer 21 into the water collection pool 3.

[0047] Reference Figure 1 Each inlet pipe 2 is connected to an electronic water processor 5. The electronic water processor 5 is an existing water processor that uses a high-frequency electromagnetic field to destroy the environment in which bacteria and algae can survive, and to form substances that are harmful to bacteria and algae, thus killing bacteria and algae. The electronic water processor 5 treats the hot water entering the tower body 1 once, reducing the possibility of algae formation.

[0048] Reference Figure 2 Furthermore, the length of the water collection tank 3 extends perpendicularly to the distribution direction of the two sets of cooling packing layers 21. Both ends of the water collection tank 3, which are far apart from each other along its length, have algae collection tanks 6. An agitating device 9 moves within the water collection tank 3 along its length. If algae grow in the water collection tank 3, the agitating device 9 moves to separate the algae and guide it to the algae collection tank 6 for centralized treatment.

[0049] Reference Figure 3 and Figure 4 Specifically, the agitation device 9 includes a baffle 91, an agitator 92, a connecting seat 93, and a rotation source 94. The baffle 91 extends vertically and includes a first plate 911 and a second plate 912 integrally formed from bottom to top. Both the first plate 911 and the second plate 912 have a square structure. The longitudinal cross-sectional dimensions of the first plate 911 are the same as those of the water collection tank 3. The lower surface of the first plate 911 abuts against the inner bottom wall of the water collection tank 3, and the opposite side walls of the first plate 911 abut against the opposite inner walls of the water collection tank 3. The first plate 911 has a hollowed-out center and a first filter screen 913 is embedded therein. The mesh of the first filter screen 913 is used to filter the water flow and block algae. The second plate 912 continues onto the upper surface of the first plate 911, so that the second plate 912 protrudes upward from the water collection tank 3, and the width of the second plate 912 extending along the width direction of the water collection tank 3 is less than the extension width of the first plate 911.

[0050] The agitator 92 includes a connecting shaft 921 and blades 922. The connecting shaft 921 is located inside the water collection tank 3 and extends along the width of the water collection tank 3. There are multiple blades 922, which are evenly spaced around the connecting shaft 921 and fixed to the outer wall of the connecting shaft 921. Each blade 922 is square plate-shaped, with its two ends facing away from each other close to the two opposite inner sidewalls of the water collection tank 3. The thickness of the blades 922 gradually decreases away from the connecting shaft 921.

[0051] The second plate 912 is provided with a through shaft 24 extending along the width of the water collection tank 3. The through shaft 24 is rotatably connected to the second plate 912, and the two ends of the through shaft 24 that are far apart from each other extend out of opposite sides of the second plate 912. There are two rod-shaped connecting seats 93, each engaging with the two ends of the through shaft 24 that are far apart from each other. Specifically, one end of the connecting seat 93 is fixedly sleeved on the outer wall of the through shaft 24, and the end of the connecting seat 93 that is far apart from the through shaft 24 is rotatably sleeved on the outer wall of the connecting shaft 921 via a bearing. The two connecting seats 93 are located at the two ends of the blade 922 that are far apart from each other.

[0052] On the upper surface of the first baffle 91, at both ends of the water collection pool 3, which are far apart from each other, there are vertically extending straight plates 25. The two ends of the shaft 24, which are far apart from each other, rotate on the two straight plates 25 respectively, and the connecting seat 93 rotates between the side wall of the second plate 912 and the straight plates 25.

[0053] The rotation source 94 is a forward and reverse motor mounted on one of the straight plates 25. The output end of the rotation source 94 is connected to the through shaft 24 so that the rotation source 94 can drive the through shaft 24 to rotate. The rotation source 94 drives the through shaft 24 to rotate so that the agitator 92 flips between the first position and the second position.

[0054] Reference Figure 3 and Figure 5 When the agitator 92 is in the first position, it is located on one side of the baffle 91. When the agitator 92 is in the second position, it is located on the opposite side of the baffle 91. When the agitator 92 is in both the first and second positions, the distance between the lowest point of the shaft 24 and the bottom wall of the water collection tank 3 is consistent with the extension width of the blade 922 along the direction perpendicular to the axis of the connecting shaft 921, allowing the agitator 92 to scrape away algae from the bottom of the water collection tank 3 when it rotates. In other embodiments, bristles can be provided on the side of the blade 922 away from the connecting shaft 921 to further improve the cleaning effect of the blade 922 on the bottom of the water collection tank 3.

[0055] Reference Figure 2 and Figure 3 A base 16 is fixed to one side of the water collection tank 3 on the upper surface of the platform 23. A screw 17 is rotatably connected to the base 16. The axis of the screw 17 is parallel to the length extension direction of the water collection tank 3, and a power source 18 for driving the screw 17 to rotate is fixed to one end of the base 16. The power source 18 is a forward and reverse reversing motor connected to the screw 17. A guide rod 26 is fixedly connected to the other side of the upper surface of the platform 23 on the water collection tank 3. The guide rod 26 and the screw 17 are located on the same horizontal plane and are parallel to each other.

[0056] Reference Figure 3 and Figure 4The upper surfaces of the two straight plates 25 are each fixed with a movable seat 19. The two movable seats 19 extend in a direction away from each other. One movable seat 19 is threaded onto the outer wall of the screw 17, and the other movable seat 19 is slidably mounted on the outer wall of the guide rod 26, so that the power source 18 drives the screw 17 to rotate, which can drive the baffle 91 to slide along the length extension direction of the water collection pool 3.

[0057] When cleaning algae in the collection tank 3, the agitator 92 is first rotated to the first position by the rotating source 94 rotating in the forward direction. Then, the screw 17 is driven to rotate in the forward direction by the power source 18, causing the baffle 91 to move from one end of the collection tank 3 to the other. At this time, the agitator 92 is located on one side of the baffle 91 in the forward direction, and the algae scraped by the agitator 92 is located on one side of the baffle 91 in the forward direction. When the baffle 91 moves to the algae collection tank 6 near the agitator 92 at one end of the collection tank 3, the rotating source 94 rotates in the reverse direction to flip the agitator 92 to the second position, so that the agitator 92 is located on the side away from the forward direction of the baffle 91. Then, the baffle 91 continues to move forward, driving the scraped algae into the algae collection tank 6. Then, the power source 18 drives the screw 17 to rotate in the opposite direction, and the baffle 91 returns along the original path, so that the agitator 92 is once again located on one side of the forward direction of the baffle 91. During the return of the baffle 91, the agitator 92 and the baffle 91 clean the water collection tank 3 again. Afterwards, the baffle 91 drives the cleaned algae to the algae collection tank 6 in another section of the water collection tank 3, so that the water collection tank 3 can be repeatedly cleaned by the back-and-forth movement of the baffle 91.

[0058] Reference Figure 3 To drive the agitator 92 to rotate and clean when the baffle 91 moves, first guide rails 10 are fixed on both inner walls of the water collection tank 3. The first guide rails 10 are rectangular strips and extend along the length of the water collection tank 3. When the agitator 92 is in the first and second positions, the two ends of the connecting shaft 921 that are far apart abut against the upper surfaces of the two first guide rails 10. The outer walls of the two ends of the connecting shaft 921 that are far apart and the upper surfaces of the first guide rails 10 are both rough surfaces. When the baffle 91 drives the connecting shaft 921 to move relative to the first guide rails 10 along the length of the water collection tank 3, the friction between the connecting shaft 921 and the first guide rails 10 drives the connecting shaft 921 to roll on the first guide rails 10, thereby driving the agitator 92 to rotate.

[0059] Reference Figure 3 and Figure 4 In addition, the first plate 911 has notches 27 on its two opposite side walls that are opposite to the first guide rail 10. The first plate 911 is slidably sleeved on the outer wall of the first guide rail 10 through the notches 27 to guide the movement of the first plate 911.

[0060] Furthermore, a bracket is fixedly extended on the baffle 91, and the bracket is fixedly mounted with second guide rails 11 corresponding one-to-one with the first guide rails 10. The second guide rails 11 have an overall arc-shaped structure and extend along the moving path of the shaft 24 between the first position and the second position. The extension angle of the second guide rails 11 is 180°, and the second guide rails 11 are mirror-symmetrical with respect to the baffle 91. On the opposite side of the two second guide rails 11, there are guide grooves 28 extending along the extension direction of the second guide rails 11. The guide grooves 28 penetrate the two far apart ends of the second guide rails 11 and the two far apart flared sections of the second guide rails 11.

[0061] When the connecting seat 93 drives the agitator 92 to rotate between the first and second positions, the two ends of the through shaft 24, which are far apart from each other, enter the two opposing guide rails from the guide groove 28 respectively. The through shaft 24 abuts against the inner bottom wall of the guide groove 28 of the second guide rail 11. The inner bottom wall of the guide groove 28 of the second guide rail 11 is a rough surface. When the through shaft 24 moves in the second guide rail 11, it rolls on the inner bottom wall of the guide groove 28 of the second guide rail 11, so that the agitator 92 rotates during the rotation. Thus, while the second guide rail 11 guides the rotation of the agitator 92, some of the algae adhering to the blade 922 can be shaken off.

[0062] Reference Figure 5 and Figure 6 In order to collect the cleaned algae in the algae collection pond 6, there is a connecting port 7 between the algae collection pond 6 and the water collection pond 3. The longitudinal cross-sectional dimensions of the algae collection pond 6 and the connecting port 7 are the same as those of the water collection pond 3. Limiting seats 29 are fixed on the two inner walls of the algae collection pond 6 opposite to the connecting port 7. A recessed groove 30 is opened on the side of the limiting seat 29 away from the inner wall of the algae collection pond 6. A gate 8 that moves up and down at the connecting port 7 to open and close the connecting port 7 is provided. The gate 8 slides up and down on the two sides of the limiting seat 29 respectively to limit the movement direction of the gate 8.

[0063] When the gate 8 moves downward to abut the bottom of the algae collection tank 6, the gate 8 closes the connection port 7, cutting off the connection path between the water collection tank 3 and the algae collection tank 6; when the gate 8 moves upward and separates from the inner bottom wall of the water collection tank 3, the water collection tank 3 and the algae collection tank 6 are connected to each other.

[0064] Specifically, the top of the gate 8 has clearance openings 31 on opposite sides along the width of the water collection pool 3. When the gate 8 closes the connecting port 7, the portion of the gate 8 with clearance openings 31 is located above the upper surface of the platform 23. A guide portion 12 is rotatably connected to the top of the gate 8 along the horizontal direction. The guide portion 12 is in the shape of a round rod, and its two far apart ends extend into the two clearance openings 31 of the gate 8.

[0065] When the agitator 92 is located on one side of the forward direction of the baffle 91, the gate 8 is subjected to its own gravity, and the lower surface of the gate 8 abuts against the bottom of the algae collection tank 6. When the agitator 92 is flipped to the side away from the forward direction of the baffle 91, and the baffle 91 is close to the algae collection tank 6, the guide part 12 abuts against the upper surface of the second guide rail 11. As the baffle 91 gradually approaches the algae collection tank 6, the guide part 12 is guided by the second guide rail 11 and gradually moves upward to open the connecting port 7.

[0066] When the baffle 91 abuts against the limiting seat 29, the bottom of the gate 8 remains within the recessed groove 30 and close to the upper surface of the platform 23, allowing the baffle 91 to move the cleaned algae from the connecting port 7 into the algae collection tank 6. When the baffle 91 moves away from the limiting seat 29 to the other end of the algae collection tank 6, the gate 8 descends under its own gravity, closing the connecting port 7 again, leaving the cleaned algae in the algae collection tank 6.

[0067] Reference Figure 3 and Figure 5 Furthermore, a filter basket 13 moves up and down inside the algae collection tank 6. The filter basket 13 is square-shaped, with an opening at the top and on the side facing the water collection tank 3. The solid part of the filter basket 13 is provided with filter holes 14, which are used to filter water and retain algae inside the filter basket 13.

[0068] The water accumulation in algae collection pond 6 and water collection pond 3 generally does not exceed half of the total water volume in algae collection pond 6 and water collection pond 3. There is a linkage 15 between filter basket 13 and gate 8. When gate 8 moves downward to close the connecting port 7, linkage 15 drives filter basket 13 to move upward out of the water surface of algae collection pond 6. When gate 8 moves upward to open the connecting port 7, linkage 15 drives filter basket 13 downward to abut the bottom of algae collection pond 6, so as to facilitate the collection of algae in algae collection pond 6.

[0069] Reference Figure 5 and Figure 6 Specifically, the linkage 15 includes a first rack 151, a second rack 152, and a gear 153. There is an installation gap between the two outer walls of the filter basket 13 and the two inner walls of the algae collection tank 6. The first rack 151 is fixed to the outer wall of the filter basket 13. The second rack 152 is fixed to the side of the gate plate 8 facing the filter basket 13, and the gear 153 is rotatably connected to the inner wall of the algae collection tank 6 via a rotating shaft. The first rack 151, the second rack 152, and the gear 153 are all located within the installation gap, with the first rack 151 and the second rack 152 parallel to each other and extending vertically. The gear 153 simultaneously meshes with both the first rack 151 and the second rack 152, thereby causing the filter basket 13 to move in the opposite direction when it moves.

[0070] Reference Figure 2Furthermore, a second filter screen 20 is installed at one end of the water outlet 4 near the inside of the water collection tank 3. The mesh of the second filter screen 20 is used to filter the water flow and block algae, so that the algae are not easily moved out of the water outlet 4.

[0071] The implementation principle of a cooling tower according to an embodiment of this application is as follows: the rotating source 94 drives the agitator 92 to rotate to the first position, and the power source 18 drives the screw 17 to rotate in the forward direction, so that the baffle 91 drives the agitator 92 to move together towards the algae collection pool 6 near one end of the water collection pool 3. At this time, the agitator 92 is located on one side of the forward direction of the baffle 91, and the agitator 92 rotates in cooperation with the first guide rail 10 to scrape and clean the algae in the water collection pool 3.

[0072] When the agitator 92 approaches the algae collection tank 6, the rotation source 94 drives the agitator 92 to rotate to the second position, placing the agitator 92 on the side of the baffle 91 opposite to the direction of travel, while the baffle 91 continues to move forward. During the forward movement of the baffle 91, the guide part 12 abuts against the second guide rail 11, and the second guide rail 11 gradually pushes the guide part 12 upward, causing the gate 8 to gradually move upward and open the connecting port 7, allowing the baffle 91 to guide the cleaned algae into the algae collection tank 6. As the gate 8 moves upward, the filter basket 13 moves downward, allowing the algae to enter the algae collection tank 6 for collection.

[0073] When the baffle 91 abuts against the limit seat 29, the power source 18 drives the screw 17 to rotate in the opposite direction, causing the baffle 91 to move in the opposite direction. The agitator 92 is then positioned on one side of the baffle 91 in the forward direction. The baffle 91 moves forward to clean the water collection tank 3 again and sends the cleaned algae into the algae collection tank 6 at the other end of the water collection tank 3 for collection.

[0074] 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.
