Abstract
Description
Technical Field
[0001] The invention relates to the field of cleaning technology, in particular to a fully automatic and efficient cleaning device. Background Art
[0002] A cooling tower places a heat exchange tube bundle inside the tower. A working fluid (pure water or other liquid) circulates in the heat exchange tube bundle. The heat of the working fluid is exchanged between the circulating air, spray water, and circulating water to ensure a cooling effect. At the same time, air outside the unit enters through the air inlet grille on the chassis, flows upward through the coil in the opposite direction of the water flow, and a small amount of water evaporates and absorbs heat. The hot and humid air is discharged into the atmosphere by the ventilator at the top of the cooling tower. The remaining spray water falls into the water pan at the bottom, is recirculated by the spray pump to the water distribution system, and then returns to the heat exchange tube bundle. Due to the dust carried in the air, after the cooling tower has been circulating for a period of time, sludge is easily attached to the surface of the heat exchange tube bundle, which affects the heat exchange effect of the heat exchange tube bundle.

[0035] The present invention provides the following embodiments
[0036] Example 1: The present invention provides a fully automatic and efficient cleaning device, such as Figure 1-Figure 3As shown, it includes a shell 1, a heat exchange cavity 30 is provided at the upper end of the shell 1, a heat exchange component is installed in the heat exchange cavity 30, and the heat exchange component includes a heat exchange tube bundle 15. Guide rail shells 17 are symmetrically provided on the left and right sides of the front and rear ends of the heat exchange cavity 30. The guide rail shell 17 is provided with a guide groove 27 at one end close to the heat exchange tube bundle 15. A guide block 24 is slidably provided in the guide groove 27. The guide block 24 is connected to the driving mechanism. A flushing mechanism is rotatably installed between the guide blocks 24 connected to the guide rail shells 17 on the left and right sides. The flushing mechanism corresponds to the guide rail shell 17 and is used to perform all-round and efficient cleaning of the heat exchange tube bundle 15.
[0037] The working principle of the above technical solution is:
[0038] The heat exchange tube bundle 15 is used for circulating the working fluid. The heat of the working fluid is ensured to have a cooling effect through heat exchange with the air and spray water circulating on the surface of the heat exchange tube bundle 15. After the working fluid circulates in the heat exchange tube bundle 15 for a certain period of time, the drive mechanism works to drive the guide block 24 to slide up and down along the guide groove 27. The guide block 24 drives the flushing mechanism to move up and down. When the flushing mechanism moves up and down reciprocatingly, it automatically performs all-round and efficient cleaning on the heat exchange tube bundle 15, cleaning the sludge on the surface of the heat exchange tube bundle 15. No manual cleaning and maintenance is required, which saves time and effort, improves the cleaning efficiency of the heat exchange tube bundle 15, and solves the technical problem that the cleaning and maintenance of the existing heat exchange tube bundle 15 are usually performed manually, and the cleaning process is time-consuming and labor-intensive.
[0039] Example 2: Based on Example 1, Figure 1-Figure 7 As shown, the flushing mechanism includes a cleaning block 22, the interior of which is provided with a liquid storage chamber, and a number of cleaning heads 23 are evenly spaced from left to right on the cleaning block 22, and the number of cleaning heads 23 are respectively connected to the liquid storage chamber, and a rotating shaft 28 is symmetrically provided at the left and right ends of the cleaning block 22, and a torsion spring is sleeved on the rotating shaft 28, and the rotating shaft 28 passes through the guide block 24 and is fixedly connected to the gear 26, and the torsion spring is fixedly arranged between the guide block 24 and the cleaning block 22, and the upper side of the gear 26 is meshed with the rack 25, and the rack 25 is slidably connected to the guide block 24, and a guide wheel is installed at the end of the rack 25 close to the guide rail housing 17;
[0040] A plurality of guide openings 18 are provided on the side of the guide rail housing 17 close to the heat exchange tube bundle 15 and away from the cleaning block 22. The plurality of guide openings 18 are evenly spaced in the vertical direction, and the guide openings 18 are in contact with the guide wheels.
[0041] The cleaning block 22 is connected to the water inlet pipe 4, which is in communication with the liquid storage chamber. The end of the water inlet pipe 4 away from the cleaning block 22 passes through the side end of the shell 1 and is in communication with the water outlet of the power pump 2. The water inlet of the power pump 2 is in communication with the water outlet pipe 3, which passes through the side end of the shell 1 and is in communication with the lower water pan of the heat exchange chamber 30. The power pump 2 is fixedly connected to the side end of the shell 1.
[0042] The driving mechanism includes a threaded rod 16 rotatably arranged in the guide groove 27, the threaded section of the threaded rod 16 is threadedly connected to the guide block 24, the cylindrical section of the threaded rod 16 passes through the upper end of the guide groove 27 and the upper end of the top cover 9 and is fixedly connected to the motor 2 11, and the motor 2 11 is fixedly set at the upper end of the top cover 9.
[0043] The working principle of the above technical solution is:
[0044] When the motor 2 11 is working, it drives the threaded rod 16 to rotate. When the threaded rod 16 rotates, it drives the guide block 24 to slide up and down along the guide groove 27. When the guide block 24 moves up and down, it drives the rack 25 to move up and down. When the rack 25 moves up and down, it drives the guide wheel connected thereto to move up and down. The guide wheel corresponds to the guide opening 18 on the guide rail housing 17. The cross-section of the guide opening 18 is triangular, and the inclination angle of the upper inclined end of the guide opening 18 is much larger than the inclination angle of the lower inclined end of the guide opening 18. An intermittent platform is provided between adjacent guide openings 18. When the guide wheel contacts the intermittent platform, the torsion spring is in a deformed state. , when the guide block 24 moves upward, after the guide wheel enters the guide opening 18 from the intermittent platform, the guide wheel first contacts the corresponding lower inclined end of the guide opening 18. As the guide block 24 moves upward, the torsion spring is reset. Under the action of the torsion spring, the rotating shaft 28 drives the gear 26 to rotate, and the gear 26 drives the rack 25 and the guide wheel to extend into the guide opening 18. During this process, the guide wheel always rolls along the lower inclined end of the guide opening 18. Since the inclination angle of the lower inclined end of the guide opening 18 is small, the guide wheel can quickly extend into the guide opening 18. At this time, the rotating shaft 28 drives the cleaning block 22 to tilt rapidly upward;
[0045] As the guide block 24 moves upward, the guide wheel disengages from the lower inclined end of the guide opening 18 and begins to contact the upper inclined end of the guide opening 18. Then, the guide wheel moves toward the intermittent platform, driving the rack 25 to move. The rack 25 drives the gear 26 to rotate in the opposite direction. Since the inclination angle of the upper inclined end of the guide opening 18 is large, the gear 26 drives the cleaning block 22 to rotate slowly downward via the rotating shaft 1 28. The cleaning block 22 drives the cleaning head 23 to rotate synchronously.
[0046] When the guide block 24 moves downward, after the guide wheel enters the guide opening 18 from the intermittent platform, the guide wheel first contacts the upper inclined end of the guide opening 18. As the guide block 24 moves downward, the rotating shaft 28 drives the gear 26 to rotate under the action of the torsion spring, and the gear 26 drives the rack 25 and the guide wheel to extend into the guide opening 18. During this process, the guide wheel rolls along the upper inclined end of the guide opening 18. Due to the large inclination angle of the upper inclined end of the guide opening 18, the guide wheel slowly extends into the guide opening 18. At this time, the rotating shaft 28 drives the cleaning block 22 to slowly tilt upward.
[0047] As the guide block 24 moves downward, the guide wheel disengages from the upper inclined end of the guide opening 18 and begins to contact the lower inclined end of the guide opening 18. The guide wheel moves toward the intermittent platform. Since the inclination angle of the lower inclined end of the guide opening 18 is small, the guide wheel drives the rack 25 to move, and the rack 25 drives the gear 26 to rotate in the opposite direction. The gear 26 drives the cleaning block 22 to rotate rapidly downward through the rotating shaft 1 28.
[0048] The cleaning block 22 drives the cleaning head 23 to move up and down along the guide block 24, and can gradually clean the heat exchange tube bundle 15 in the vertical direction. Guide rail shells 17 are symmetrically provided on the front and rear ends and the left and right sides of the heat exchange chamber 30. A flushing mechanism is rotatably installed between the guide blocks 24 connected to the left and right guide rail shells 17. Therefore, the flushing mechanism is distributed on the front and rear sides of the heat exchange chamber 30. The cleaning blocks 22 in the flushing mechanism are evenly spaced from left to right and have a plurality of cleaning heads 23. Therefore, the plurality of cleaning heads 23 can clean the heat exchange tube bundle 15 in the front and rear directions, the left and right directions, and the top and bottom directions, thereby achieving all-round and efficient cleaning of the heat exchange tube bundle 15.
[0049] Since there is a gap between the horizontal sections of the heat exchange tube bundle 15, each horizontal section of the heat exchange tube bundle 15 is correspondingly provided with a guide opening 18. When the guide block 24 moves upward and the guide wheel disengages from one guide opening 18 and enters the guide opening 18 adjacent to it, since the guide wheel first contacts the lower inclined end of the guide opening 18, the rotating shaft 128 can quickly drive the cleaning block 22 to rotate from the lower side to the upper side, so that the cleaning head 23 originally cleans the upper area of a horizontal section of the heat exchange tube bundle 15 when it is facing downward, and can quickly rotate upward to clean the lower area of another horizontal section adjacent to the horizontal section of the heat exchange tube bundle 15 above the horizontal section, reducing the time for the cleaning head 23 to face the gap between the two horizontal sections, improving the cleaning efficiency, and avoiding the cleaning head 23 spraying water towards the air, causing waste of resources. Then, as the guide block 24 drives the cleaning block 22 to gradually move upward, the purpose of the cleaning head 23 moving upward and gradually rotating downward is achieved, and the horizontal section of the heat exchange tube bundle 15 corresponding to the cleaning head 23 is gradually cleaned from the lower area to the upper area;
[0050] When the guide block 24 moves downward, the guide wheel disengages from one guide opening 18 and enters the adjacent guide opening 18 below it. The cleaning head 23 moves downward while gradually rotating upward, gradually cleaning the horizontal section of the heat exchange tube bundle 15 corresponding to the cleaning head 23 from the upper area to the lower area, and then quickly rotates from the upper side to the downward side. When the cleaning head 23 is originally facing upward, it cleans the lower area of one horizontal section of the heat exchange tube bundle 15. It can quickly rotate downward and clean the upper area of another horizontal section of the heat exchange tube bundle 15 below the horizontal section of the heat exchange tube bundle 15. Regardless of how the cleaning head 23 rotates, the U-shaped section of the heat exchange tube bundle 15 will be flushed.
[0051] A water pan is provided at the lower side of the heat exchange chamber 30. When the power pump 2 is working, the sprayed water collected in the water pan at the lower side of the heat exchange chamber 30 can be pumped out through the water outlet pipe 3, and then the water is pressurized and sent into the liquid storage chamber inside the cleaning block 22 through the water inlet pipe 4. The water inlet pipe 4 is a hose that can move freely with the up and down movement of the cleaning block 22 to ensure the normal supply of water in the liquid storage chamber. The pressurized water is sprayed out through the cleaning head 23 to pressure-wash the heat exchange tube bundle 15.
[0052] Example 3: Based on Example 2, Figure 1-Figure 7 As shown, the top cover 9 is fixedly arranged on the upper end of the housing 1. The upper end of the top cover 9 is also fixedly provided with a motor 10. The motor 10 is fixedly connected to the drive shaft. The drive shaft passes through the upper end of the top cover 9, enters the heat exchange cavity 30, and is fixedly connected to the air guide fan 13.
[0053] The heat exchange assembly also includes a power pump 29 fixedly connected to the left end of the shell 1. The water inlet of the power pump 29 is connected to the water pipe 2, which is respectively connected to the external water tank and the water pan at the bottom of the heat exchange chamber 30. The water outlet of the power pump 29 is connected to the water pipe 12, which is connected to the spray pipe 14. The spray pipe 14 is installed on the upper side of the heat exchange chamber 30. A number of spray heads are evenly spaced on the lower side of the spray pipe 14 in the heat exchange chamber 30. The several spray heads are correspondingly arranged on the upper side of the heat exchange tube bundle 15. The upper water inlet of the heat exchange tube bundle 15 is connected to the water inlet pipe 2 6, and the lower side of the heat exchange tube bundle 15 is connected to the water outlet pipe 2 8. The water inlet pipe 2 6 passes through the upper right end of the shell 1 and is connected to the water inlet pump 5. The water outlet pipe 2 8 passes through the lower right end of the shell 1 and is connected to the water outlet pump 7. The water inlet pump 5 and the water outlet pump 7 are both fixedly arranged at the right end of the shell 1.
[0054] The working principle of the above technical solution is:
[0055] When the motor 10 is working, it drives the drive shaft to rotate, and the drive shaft drives the air guide fan 13 to work. The air guide fan 13 discharges the hot and humid air in the heat exchange chamber 30. When the power pump 2 29 is working, it can send the water collected at the lower side of the heat exchange chamber 30 into the spray pipe 14 through the water supply pipe 2 and the water supply pipe 12. The spray head of the spray pipe 14 sprays water onto the heat exchange tube bundle 15 to exchange heat with the working fluid in the heat exchange tube bundle 15. Part of the sprayed water falls at the lower end of the heat exchange chamber 30 and is collected. The external water tank is used to provide spray water. When the water stored at the lower end of the heat exchange chamber 30 is insufficient to clean the heat exchange tube bundle 15, water can also be supplied to avoid the water volume at the lower end of the heat exchange chamber 30 not meeting the spraying demand. The water inlet pump 5 and the water outlet pump 7 work to circulate the working fluid in the heat exchange tube bundle 15. A descaling agent can be added to the water to remove scale attached to the surface of the heat exchange tube bundle 15 when cleaning the heat exchange tube bundle 15.
[0056] Example 4: Based on Example 1, Figure 1 、 Figures 8-15 As shown, a filter recovery mechanism is installed on the lower side of the heat exchange chamber 30, and the filter recovery mechanism includes a filter plate 19. The filter plate 19 is correspondingly arranged on the lower side of the heat exchange tube bundle 15. The filter plate 19 is slidably connected to the rear end of the heat exchange chamber 30. The left and right sides of the filter plate 19 are symmetrically provided with movable grooves 34. A threaded rod 2 42 is rotatably provided in the movable groove 34. The threaded section of the threaded rod 2 42 is threadedly connected to the fixed block 51. The fixed block 51 is slidably connected to the movable groove 34. A mounting block 2 50 is fixed on the upper side between the fixed blocks 51 slidably connected in the movable grooves 34 on the left and right sides. The lower side of the mounting block 2 50 The end is fixedly connected to the scraper 41, and the scraper 41 is correspondingly arranged on the upper side of the filter plate 19. The fixed block 51 and the movable opening of the sliding block 35 are slidably matched, and a return spring 52 is fixedly provided between the movable opening of the sliding block 35 and the fixed block 51. A mounting block 48 is fixedly provided on the lower side between the sliding blocks 35 connected by the fixed blocks 51 on the left and right sides. A plurality of push rods 49 are evenly spaced along the left and right directions at the upper end of the mounting block 48. The number of the plurality of push rods 49 is the same as the number of filter holes evenly spaced along the same straight line direction on the left and right sides of the filter plate 19, and the push rods 49 correspond to the filter holes.
[0057] A number of matching blocks 43 are evenly spaced along the front-to-back direction on the lower side of the movable groove 34. The matching blocks 43 are installed on the filter plate 19. The matching blocks 43 are fixedly connected to the filter plate 19. The number of matching blocks 43 is the same as the number of filter holes evenly spaced along the same straight line direction on the filter plate 19. The sliding blocks 35 connected to the fixed blocks 51 on the left and right sides are provided with matching grooves 47 at the ends close to each other, and the matching grooves 47 correspond to the matching blocks 43.
[0058] The working principle of the above technical solution is:
[0059] When the spray water and the water for cleaning the heat exchange tube bundle 15 fall downwards to the lower end of the heat exchange chamber 30, they first pass through the filter plate 19 to filter the sludge and impurities in the water, ensuring as much as possible that there are no impurities in the water at the lower end of the heat exchange chamber 30, avoiding blockage of the water supply pipe 2, the water outlet pipe 1 3 and the spray head and the cleaning head 23 that are finally sprayed with water connected to the heat exchange chamber 30. When cleaning the sludge and impurities on the filter plate 19, the threaded rod 2 42 rotates, which can drive the fixed block 51 to slide back and forth along the movable groove 34. The fixed block 51 drives the scraper 41 to move through the mounting block 2 50. The scraper 41 scrapes off the sludge and impurities on the upper side of the filter plate 19. The scraper 41 moves from back to front, scrapes off the sludge and impurities on the filter plate 19 and pushes them to the front side of the filter plate 19. When the fixed block 51 slides along the movable groove 34, it drives the sliding block 35 to move synchronously. After the matching groove 47 on the sliding block 35 is matched with the matching block 43, the inclined end of the matching groove 47 contacts the inclined end of the matching block 43, which can push the sliding block 35 to move upward, and the movable opening of the sliding block 35 moves upward along the fixed block 51. The return spring 52 is compressed, and when the sliding block 35 moves upward, it drives the mounting block 1 48 to move upward, and the mounting block 1 48 drives the pushing rod 49 to move upward. The mounting block 1 48 moves forward and backward at the same time as the sliding block 35. Therefore, the pushing rod 49 will move up and down while moving forward and backward. When the pushing rod 49 moves upward, it will extend into the filter holes on the filter plate 19 and dredge them. The pushing rod 49 is located at the front side of the scraper 41. First, the sludge impurities attached to the filter holes are pushed into the upper end of the filter plate 19, and then the sludge impurities on the filter plate 19 are scraped to the front side of the filter plate 19 by the scraper 41.
[0060] Optionally, the push rod 49 is set to a needle shape, so that its diameter is much smaller than the diameter of the filter hole on the filter plate 19, and it has a certain stroke in the filter hole on the filter plate 19, ensuring that it can move back and forth with the mounting block 48 when in the filter hole on the filter plate 19, and the push rod 49 can move up and down quickly to avoid contact with the side wall of the filter hole on the filter plate 19 and damage to the push rod 49; optionally, the push rod 49 can also be set to an elastic rod, and a roller is provided on the upper side of the elastic rod, and the diameter of the push rod 49 is set to be slightly smaller than the diameter of the filter hole on the filter plate 19. When the push rod 49 moves upward, the roller is first in contact with the lower end of the filter plate 19. The setting of the roller can reduce the friction between the push rod 49 and the filter plate 19, reducing the push rod 49 The deformation along the left and right horizontal directions makes it deform as much as possible in the upper and lower vertical directions until the push rod 49 moves to the corresponding position on the lower side of the filter hole. Under the action of elasticity, the push rod 49 directly extends into the filter hole, pushing the sludge impurities in the filter hole to the upper side of the filter plate 19. Then, with the movement of the mounting block 48, the push rod 49 is deformed along the left and right horizontal directions until the push rod 49 breaks away from the filter hole on the filter plate 19. The number of push rods 49 is the same as the number of filter holes evenly spaced along the same straight line direction on the left and right of the filter plate 19. The lower side of the movable groove 34 is evenly spaced along the same straight line direction front and back, so that the push rod 49 can clear all the filter holes on the filter plate 19 when the mounting block 48 moves.
[0061] Example 5: Based on Example 4, Figures 1-15 As shown, the front end of the filter plate 19 is fixedly connected to the working block 32, the working block 32 corresponds to the working chamber 38 on the rear side of the upper end of the connecting block 31, the rear end of the connecting block 31 is fixedly connected to the limit block 39, the inclined end of the limit block 39 corresponds to the inclined end of the working block 32, the front and rear ends of the connecting block 31 are penetrated by a discharge cavity 36, the connecting block 31 passes through the front end of the shell 1 and is fixedly connected to the fixed plate 20, the connecting block 31 is slidably connected to the front end of the shell 1, a number of springs 40 and an electric telescopic cylinder are fixed between the fixed plate 20 and the shell 1, and the front and rear ends of the fixed plate 20 are penetrated by The discharge chamber 21, the discharge chamber 21, the discharge chamber 1 36 and the working chamber 38 are connected in sequence from front to back. The left and right sides of the rear end of the connecting block 31 are symmetrically provided with open grooves 37. The open grooves 37 correspond to the threaded rod 2 42 and the clamping block 45. The cylindrical section of the threaded rod 2 42 passes through the front end of the movable groove 34 and is fixedly connected to the clamping block 45. The clamping block 45 cooperates with the clamping groove 46 on the rotating shaft 2 44. The rotating shaft 2 44 is correspondingly arranged in the open groove 37, and the rotating shaft 2 44 passes through the front end of the open groove 37 and is fixedly connected to the motor 33. The motor 33 is fixedly connected to the front end of the connecting block 31.
[0062] The working principle of the above technical solution is:
[0063] When there is enough sludge attached to the filter plate 19, the filter plate 19 drives the working block 32 and the threaded rod 2 42 to move downward under the action of gravity, and the threaded rod 2 42 drives the card block 45 to move downward. After the inclined end of the working block 32 contacts the inclined end of the limit block 39, it pushes the limit block 39 to move forward, and the limit block 39 drives the connecting block 31 to move forward. The connecting block 31 drives the fixed plate 20 and the motor 33 to move forward, and the motor 33 drives the rotating shaft 2 44 to move forward. A number of springs 40 are stretched, and the electric telescopic cylinder also extends freely until the working block 32 contacts the horizontal section of the limit block 39 and cannot move downward. At this time, the upper end of the working block 32 is flush with the lower side of the discharge chamber 1 36, and the working block 3 2 The discharge chamber 1 36 is no longer blocked, and the clamping block 45 just fits with the clamping groove 46 on the rotating shaft 2 44. At this time, the motor 33 is started, and the motor 33 drives the clamping block 45 to rotate through the rotating shaft 2 44. The clamping block 45 drives the threaded rod 2 42 to rotate, so that the fixed block 51 drives the scraper 41 to move through the mounting block 2 50. The scraper 41 scrapes the sludge and impurities on the upper side of the filter plate 19. The scraper 41 moves from back to front, scrapes the sludge and impurities on the filter plate 19 and pushes them to the front side of the filter plate 19, and is discharged to the outside through the discharge chamber 1 36 and the discharge chamber 2 21. A collection box is set at the corresponding position of the discharge chamber 2 21 to facilitate the storage of the scraped sludge and impurities, completing the automatic cleaning of the filter plate 19.
[0064] A distance sensor can be set at one end of the fixed plate 20 close to the shell 1. After the working block 32 contacts the horizontal section of the limit block 39 and cannot move downward, the distance between the fixed plate 20 and the shell 1 remains fixed and cannot change. At this time, the distance sensor detects that the distance between the fixed plate 20 and the shell 1 always remains fixed, and the detection value is the target distance between the fixed plate 20 and the shell 1 after the working block 32 cannot move downward. The distance sensor automatically controls the motor 3 33 and the electric telescopic cylinder to work through the controller. The electric telescopic cylinder cannot be extended or retracted, so as to avoid the weight on the filter plate 19 changing after some sludge impurities are discharged during the automatic cleaning process of the filter plate 19. A number of springs 40 drive the fixed plate 20 to bring The movable filter plate 19 moves. After the automatic cleaning of the filter plate 19 is completed, that is, the scraper 41 cannot move forward any further, and the sludge and impurities on the filter plate 19 are discharged to the outside from the discharge chamber 1 36 and the discharge chamber 2 21, the electric telescopic cylinder stops working. At this time, the electric telescopic cylinder is free to extend and retract. Under the elastic action of the plurality of springs 40, the fixed plate 20 drives the connecting block 31 to return to its original position, and the connecting block 31 pushes the filter plate 19 to move upward and return to its original position. The setting of the filter recovery mechanism is used to filter and recover impurities in the spray water and the cleaning water to prevent them from being deposited in the heat exchange chamber 30 and affecting the subsequent heat exchange work of the heat exchange tube bundle 15. Regular maintenance of the interior of the heat exchange chamber 30 is time-consuming and labor-intensive.

Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
