Description

Technical Field

[0001] The present invention relates to the technical field of cooling towers, and particularly to a cooling tower with adjustable spray angles. Background Art

[0002] A cooling tower is a common industrial device in daily industrial production. Its function is to spray circulating cooling water in the cooling tower, making it directly contact with air, and dissipating the carried heat into the atmosphere through evaporation and convection, so as to achieve the cooling treatment of the circulating water.

[0003] A patent with the patent announcement number CN212133429U discloses a spray mechanism of a cooling tower, including a base. The top of the base is fixedly connected with a tower body. The top of the tower body is provided with a cover plate. The top of the cover plate is fixedly connected with a transmission box. Both sides of the tower body are fixedly connected with cooling pumps. The output end of the cooling pump is communicated with a spray pipe, and the side of the spray pipe far away from the cooling pump extends into the interior of the tower body. This patent can achieve the effect of evenly spraying the coolant. This patent solves the problem that in the existing cooling tower, when spraying the coolant, it is just simply poured into the tower, which will make the coolant very uneven and cause the coolant to accumulate in a certain place, enhancing the practicability of the cooling tower.

[0004] However, the current cooling tower has the following problems: The cooling tower adjusts the angle of the spray pipes in a horizontal adjustment manner, and it is still difficult to evenly spray the positions between the gaps of multiple spray pipes, and the coverage area of the sprayed water is small, resulting in poor cooling effect of the circulating water and reduced cooling efficiency. Therefore, it is very necessary to design a cooling tower with adjustable spray angles that can spray water evenly in all directions. Summary of the Invention

[0005] The purpose of the present invention is to provide a cooling tower with adjustable spray angles to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A cooling tower with adjustable spray angles, including a cooling tower main body. A fan assembly is arranged at the top of the cooling tower main body. A circulating pipe is arranged inside the cooling tower main body. It further includes a spray device, a flapping device, a filtering device, and a water scraping device; Among them, the spraying device includes a pushing component, a circulation pump, a branch pipe, a positioning rod, a spraying pipe, a toothed plate, a toothed ring, a convex column disk and a strip groove plate. The circulation pump is fixed at the lower outer wall of the cooling tower main body. The branch pipe is fixed above the outer wall of the cooling tower main body. The branch pipe is connected to the water outlet of the circulation pump through a pipeline. The positioning rod is fixed on the left inner wall of the cooling tower main body. The spraying pipe is sleeved and rotatably installed between the outer wall of the branch pipe of the branch pipe and the outer wall of the positioning rod. A spring is arranged between the spraying pipe and the positioning rod. The circulation pump pumps the water in the cooling tower main body to the branch pipe. The branch pipe of the branch pipe transmits the water to the spraying pipe and sprays it out. The sprayed water will be sprinkled on the circulation pipe for heat exchange. The toothed ring is fixed on the right outer wall of the spraying pipe. The strip groove plate is slidably installed inside the cooling tower main body. The convex column disk is fixed at the bottom of the fan assembly. Convex columns are fixed at the bottom edge of the convex column disk. The convex columns of the convex column disk are slidably installed inside the strip grooves of the strip groove plate. The toothed plate is fixed at the right bottom of the strip groove plate. The toothed plate meshes with the toothed ring. The pushing component is arranged on the right side of the toothed plate. At the same time, the rotating shaft of the fan assembly drives the convex column disk to rotate. The convex columns of the convex column disk drive the strip groove plate to reciprocate. The strip groove plate drives the toothed plate to drive the toothed ring to rotate. The toothed ring drives the spraying pipe to rotate outside the positioning rod, so that the spraying pipe rotates and evenly sprays water, thus avoiding the problem that the existing method of horizontally adjusting the spraying pipe has a small coverage area of the sprayed water and poor cooling effect of the circulating water.

[0007] According to the above technical solution, the pushing component includes a U-shaped column plate, an L-shaped push rod and a U-shaped frame. The U-shaped column plate is fixed on the right side of the toothed plate. The U-shaped frame is fixed at the top of the outer wall of the branch pipe of the branch pipe. The L-shaped push rod is slidably installed inside the U-shaped frame, and a spring is arranged between the L-shaped push rod and the U-shaped frame. A push column is fixed at the right bottom of the U-shaped column plate. The right side of the L-shaped push rod is located on the movement track of the push column of the U-shaped column plate. The left side of the L-shaped push rod contacts the right outer wall of the spraying pipe. At the same time, the toothed plate drives the U-shaped column plate to push the right side of the L-shaped push rod to drive the L-shaped push rod to move away from the U-shaped frame. The L-shaped push rod pushes the spraying pipe towards the positioning rod, so that the spraying pipe can move horizontally while rotating, thereby increasing the coverage area of the sprayed water.

[0008] According to the above technical solution, the fanning device includes a water throwing component, a drive box, a rotating rod and four T-shaped blades. The drive box is embedded and fixed on the right side of the cooling tower main body. The rotating rod is rotatably installed inside the cooling tower main body. The rotating rod is driven by the drive box. The four T-shaped blades are evenly fixed on the outer wall of the rotating rod. A water throwing component is arranged on the outer wall of the T-shaped blade. The drive box drives the rotating rod to rotate. The rotating rod drives the T-shaped blades to fan the air around the circulation pipe, thereby accelerating the air circulation speed around the circulation pipe and improving the heat exchange efficiency of the circulation pipe.

[0009] According to the above technical scheme, the water-throwing assembly includes a port plate, a folding bag, a resistance rod and an arc block ring. The port plate is slidably installed on the outer wall of the T-shaped leaf. The folding bag is fixed between the side of the T-shaped leaf away from the rotating rod and the port plate, and the folding bag is connected with the inside of the port plate. The resistance rod is fixed on the left side of the port plate. The arc block ring is fixed on the left side of the inner wall of the cooling tower body. An arc block is fixed on the outer wall of the arc block ring. The resistance rod is located on the arc block movement trajectory of the arc block ring. At the same time, the arc block of the arc block ring pushes the resistance rod to drive the port plate toward the folding bag. The port plate pushes the folding bag to absorb the sprayed water into the port plate. When the T-shaped leaf drives the port plate to rotate, the port plate throws the internal water onto the circulation pipe, thereby improving the heat exchange efficiency of the circulation pipe in contact with water.

[0010] According to the above technical solution, the filtering device includes a vibration-free assembly, a filter screen and a spring plate. The filter screen is slidably installed inside the cooling tower body, and the spring plate is arranged between the bottom of the filter screen and the bottom of the inner wall of the cooling tower body. A vibration-free assembly is arranged above the filter screen. Through the arrangement of the filter screen, the filter screen intercepts impurities contained in the water sprayed from the spray pipe, thereby avoiding the problem of blockage caused by the circulation pump sucking in impurities.

[0011] According to the above technical scheme, the vibration-off assembly includes a protrusion ring, a curved rod, two L-shaped rods and four impact rods. The protrusion ring is fixed at the right outer wall of the rotating rod, the curved rod is fixed at the right top of the filter screen, the two L-shaped rods are respectively fixed at the front and back of the curved rod, and the four impact rods are respectively fixed at the left upper and lower outer walls of the two L-shaped rods. A protrusion is fixed on the outside of the protrusion ring, and the top of the curved rod is located on the protrusion movement trajectory of the protrusion ring. The impact rod contacts the outer wall of the circulation pipe. At the same time, the protrusion of the protrusion ring pushes the curved rod to drive the L-shaped rod to move, and the L-shaped rod drives the impact rod to impact the circulation pipe, so that the circulation pipe vibrates, and the circulation pipe shakes off the scale attached to the outer wall of the circulation pipe, thereby avoiding the formation of scale on the outside of the circulation pipe by calcium, magnesium ions and acid carbonates contained in the water, which leads to a decrease in the heat exchange effect of the cooling tower main body.

[0012] According to the above technical solution, the wiper device includes a knocking assembly, two T-shaped slides and a plurality of scrapers. The two T-shaped slides are respectively fixed on the left and right sides of the top of the groove plate, and the plurality of scrapers are evenly fixed on the side of the T-shaped slide away from the inside of the cooling tower body. The knocking assembly is arranged below the T-shaped slide. The groove plate drives the T-shaped slide to move synchronously. The T-shaped slide drives the scraper to scrape off the water vapor droplets on the top of the inner wall of the cooling tower body, and the scraped water falls back into the cooling tower body, thereby avoiding the problem that the water vapor column is blown and volatilized by the wind flow generated by the fan assembly, causing damage and loss of cooling water.

[0013] According to the above technical solution, the knocking assembly includes an L-shaped telescopic rod, a knocking rod, and a bump rod. The L-shaped telescopic rod is fixed to the bottom of the T-shaped slide plate. The knocking rod is fixed to the telescopic end of the L-shaped telescopic rod. One end of the knocking rod away from the telescopic end of the L-shaped telescopic rod contacts the bottom of the T-shaped slide plate. The bump rod is fixed to the upper outer wall of the cooling tower body. A bump is fixed to the bottom of the bump rod. The bump of the bump rod is located on the movement track of the telescopic end of the L-shaped telescopic rod. At the same time, the T-shaped slide plate drives the L-shaped telescopic rod to move. The bump of the bump rod pushes the telescopic end of the L-shaped telescopic rod to drive the knocking rod to knock on the T-shaped slide plate. The T-shaped slide plate vibrates and drives the scraper to vibrate, thereby promoting the efficiency of the scraper to scrape off water vapor beads.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: (1) Through the setting of the spraying device in the present invention, the circulating pump, the cooling tower body, the branch pipe, and the spraying pipe cooperate to sprinkle water on the circulating pipe for heat exchange. At the same time, the fan assembly, the convex column disc, the strip groove plate, the toothed plate, and the toothed ring cooperate to drive the spraying pipe to rotate outside the positioning rod, so that the spraying pipe rotates to evenly sprinkle water, thus avoiding the problem that the existing method of horizontally adjusting the spraying pipe has a small coverage area of the sprayed water, resulting in poor cooling effect of the circulating water. At the same time, the strip groove plate, the toothed plate, the U-shaped column plate, the L-shaped push rod, and the U-shaped frame cooperate to make the L-shaped push rod push the spraying pipe towards the positioning rod, so that the spraying pipe can move horizontally while rotating, thereby increasing the coverage area of the sprayed water.

[0015] (2) Through the setting of the fanning device in the present invention, the driving box and the rotating rod cooperate to drive the T-shaped blade to fan the air around the circulating pipe, thereby accelerating the air circulation speed around the circulating pipe and improving the heat exchange efficiency of the circulating pipe. At the same time, the T-shaped blade, the through-hole plate, the abutting rod, the arc-shaped block ring, and the folding bladder cooperate to make the folding bladder suck the sprayed water into the through-hole plate. When the T-shaped blade drives the through-hole plate to rotate, the through-hole plate throws the water inside onto the circulating pipe, thereby improving the heat exchange efficiency of the contact between the circulating pipe and the water.

[0016] (3) Through the setting of the filtering device in the present invention, the filter screen intercepts the impurities contained in the water sprayed by the spraying pipe, thereby avoiding the problem that the circulating pump is easily blocked after inhaling impurities. At the same time, the rotating rod, the convex block ring, the arc-shaped rod, the L-shaped rod, the elastic plate, and the filter screen cooperate to drive the impact rod to impact the circulating pipe. The circulating pipe vibrates, and the circulating pipe shakes off the scale adhering to the outer wall of the circulating pipe, thereby avoiding the problem that calcium, magnesium ions, and acid hydrogencarbonates contained in the water form scale outside the circulating pipe, resulting in a decrease in the heat exchange effect of the cooling tower body.

[0017] (4) The present invention provides a water scraping device so that the groove plate and the T-shaped slide plate cooperate to drive the scraper to scrape off the water vapor droplets on the top of the inner wall of the cooling tower body, and the scraped water falls back into the cooling tower body, thereby avoiding the problem that the water vapor column is blown and volatilized by the wind flow generated by the fan assembly, causing damage and loss of cooling water; at the same time, the T-shaped slide plate, the L-shaped telescopic rod, the bump rod and the L-shaped telescopic rod cooperate to drive the knocking rod to knock the T-shaped slide plate, and the T-shaped slide plate vibrates and drives the scraper to vibrate, thereby promoting the efficiency of the scraper to scrape off the water vapor droplets.

At the same time, the rotating shaft of the fan assembly 11 drives the convex column disk 28 to rotate, the convex column of the convex column disk 28 drives the strip groove plate 29 to reciprocate, the strip groove plate 29 drives the toothed plate 26 to drive the toothed ring 27 to rotate, and the toothed ring 27 drives the spraying pipe 25 to rotate outside the positioning rod 24, so that the spraying pipe 25 rotates to evenly spray water, thus avoiding the problem that the existing method of horizontally adjusting the spraying pipe 25 has a small coverage area of the sprayed water and poor cooling effect of the circulating water.

[0021] The pushing assembly 21 includes a U-shaped column plate 211, an L-shaped push rod 212 and a U-shaped frame 213. The U-shaped column plate 211 is fixed on the right side of the tooth plate 26, and the U-shaped frame 213 is fixed on the top of the outer wall of the branch pipe of the branch pipe 23. The L-shaped push rod 212 is slidably installed in the U-shaped frame 213, and a spring is provided between the L-shaped push rod 212 and the U-shaped frame 213. A push column is fixed to the right bottom of the U-shaped column plate 211, and the right side of the L-shaped push rod 212 is located on the push column movement trajectory of the U-shaped column plate 211. The left side of the L-shaped push rod 212 contacts the right outer wall of the spray pipe 25.

[0022] The fanning device 3 includes a water-throwing assembly 31, a driving box 32, a rotating rod 33 and four T-shaped leaves 34. The driving box 32 is embedded in the right side of the cooling tower body 1. The rotating rod 33 is rotatably installed inside the cooling tower body 1. The rotating rod 33 is driven by the driving box 32. The four T-shaped leaves 34 are evenly fixed on the outer wall of the rotating rod 33. The outer wall of the T-shaped leaves 34 is provided with a water-throwing assembly 31. The driving box 32 drives the rotating rod 33 to rotate, and the rotating rod 33 drives the T-shaped leaves 34 to fan the air around the circulation pipe 12, thereby accelerating the speed of air circulation around the circulation pipe 12 and improving the efficiency of heat exchange in the circulation pipe 12.

[0023] The water-removing assembly 31 includes a through-hole plate 311, a folding capsule 312, a resistance rod 313 and an arc block ring 314. The through-hole plate 311 is slidably mounted on the outer wall of the T-shaped leaf 34. The folding capsule 312 is fixed between the side of the T-shaped leaf 34 away from the rotating rod 33 and the through-hole plate 311, and the folding capsule 312 is connected to the inside of the through-hole plate 311. The resistance rod 313 is fixed on the left side of the through-hole plate 311. The arc block ring 314 is fixed on the left side of the inner wall of the cooling tower body 1. The outer wall of the arc block ring 314 is fixed to the left side of the inner wall of the cooling tower body 1. An arc block is fixed to the wall, and the resistance rod 313 is located on the arc block movement trajectory of the arc block ring 314. At the same time, the arc block of the arc block ring 314 pushes the resistance rod 313 to drive the port plate 311 to lean against the folding bag 312. The port plate 311 pushes the folding bag 312 to absorb the sprayed water into the port plate 311. When the T-shaped leaf 34 drives the port plate 311 to rotate, the port plate 311 throws the internal water onto the circulation pipe 12, thereby improving the heat exchange efficiency of the circulation pipe 12 in contact with water.

[0024] In use, the circulating pump 22 and the fan assembly 11 are started. The circulating pump 22 pumps the water in the cooling tower main body 1 to the branch pipe 23. The branch pipes of the branch pipe 23 transmit the water to the spraying pipe 25 and spray it out. The sprayed water will be sprinkled on the circulating pipe 12 for heat exchange. At the same time, the rotating shaft of the fan assembly 11 drives the convex column disk 28 to rotate. The convex columns of the convex column disk 28 move along the inner circumference of the strip groove plate 29. The convex columns of the convex column disk 28 drive the strip groove plate 29 to reciprocate inside the cooling tower main body 1. The strip groove plate 29 drives the toothed plate 26 to move synchronously. Since the toothed plate 26 meshes with the toothed ring 27, therefore, the toothed plate 26 will cause the toothed ring 27 to rotate. The toothed ring 27 drives the spraying pipe 25 to rotate outside the positioning rod 24, so that the spraying pipe 25 rotates and sprays water evenly, thus avoiding the problem that the existing method of horizontally adjusting the spraying pipe 25 has a small coverage area of the sprayed water and poor cooling effect of the circulating water. At the same time, when the strip groove plate 29 drives the toothed plate 26 to move, the toothed plate 26 drives the U-shaped column plate 211 to move along. The push column of the U-shaped column plate 211 pushes the right side of the L-shaped push rod 212 to drive the L-shaped push rod 212 to move away from the U-shaped frame 213. The L-shaped push rod 212 pushes the spraying pipe 25 to move towards the positioning rod 24, so that the spraying pipe 25 can move horizontally while rotating, thereby increasing the coverage area of the sprayed water.

[0025] The drive box 32 is started. The drive box 32 drives the rotating rod 33 to rotate. The rotating rod 33 drives the T-shaped blade 34 to fan the air around the circulating pipe 12, thereby accelerating the air circulation speed around the circulating pipe 12 and improving the heat exchange efficiency of the circulating pipe 12. At the same time, the T-shaped blade 34 drives the contact rod 313 to rotate through the through-hole plate 311. The arc block of the arc block ring 314 pushes the contact rod 313 to drive the through-hole plate 311 to lean towards the folding bladder 312. The folding bladder 312 is compressed. When the arc block of the arc block ring 314 does not push the contact rod 313, under the elastic force of the folding bladder 312, the folding bladder 312 drives the through-hole plate 311 to reset. At the same time, the folding bladder 312 sucks the sprayed water into the through-hole plate 311. When the T-shaped blade 34 drives the through-hole plate 311 to rotate, the through-hole plate 311 throws the water inside onto the circulating pipe 12, thereby improving the heat exchange efficiency of the contact between the circulating pipe 12 and the water. Embodiment 2

[0026] Please refer to Figures 1-9 , based on Embodiment 1, in this embodiment, a filtering device 4 and a water scraping device 5 are further included; The filtering device 4 includes a vibration and detachment component 41, a filter net 42, and a spring plate 43. The filter net 42 is slidably installed inside the cooling tower main body 1. The spring plate 43 is arranged between the bottom of the filter net 42 and the bottom of the inner wall of the cooling tower main body 1. The vibration and detachment component 41 is arranged above the filter net 42. Through the arrangement of the filter net 42, the filter net 42 intercepts the impurities contained in the water sprayed by the spray pipe 25, thereby avoiding the problem that the circulating pump 22 is easily blocked after inhaling impurities.

[0027] The vibration and detachment component 41 includes a convex ring 411, an arc-shaped rod 412, two L-shaped rods 413, and four impact rods 414. The convex ring 411 is fixed to the outer wall on the right side of the rotating rod 33. The arc-shaped rod 412 is fixed to the top on the right side of the filter net 42. The two L-shaped rods 413 are respectively fixed to the front and back of the arc-shaped rod 412. The four impact rods 414 are respectively fixed to the outer walls above and below the left side of the two L-shaped rods 413. A convex block is fixed to the outside of the convex ring 411. The top of the arc-shaped rod 412 is located on the movement track of the convex block of the convex ring 411. The impact rods 414 are in contact with the outer wall of the circulation pipe 12. At the same time, the convex block of the convex ring 411 pushes the arc-shaped rod 412 to drive the L-shaped rod 413 to move. The L-shaped rod 413 drives the impact rods 414 to impact the circulation pipe 12. The circulation pipe 12 vibrates, and the circulation pipe 12 shakes off the water scale attached to the outer wall of the circulation pipe 12, thereby avoiding the problem that calcium, magnesium ions, and acid hydrogencarbonates contained in the water form water scale outside the circulation pipe 12, resulting in a decrease in the heat exchange effect of the cooling tower main body 1.

[0028] The water scraping device 5 includes a knocking component 51, two T-shaped sliding plates 52, and several scraping plates 53. The two T-shaped sliding plates 52 are respectively fixed to the left and right sides of the top of the strip groove plate 29. The several scraping plates 53 are evenly fixed to the side of the T-shaped sliding plate 52 away from the inside of the cooling tower main body 1. The knocking component 51 is arranged below the T-shaped sliding plate 52. The strip groove plate 29 drives the T-shaped sliding plate 52 to move synchronously. The T-shaped sliding plate 52 drives the scraping plates 53 to scrape off the water vapor beads on the top of the inner wall of the cooling tower main body 1. The scraped water falls back into the cooling tower main body 1, thereby avoiding the problem that the water vapor column is blown and volatilized by the air flow generated by the fan component 11, resulting in damage and loss of the cooling water.

[0029] The knocking component 51 includes an L-shaped telescopic rod 511, a knocking rod 512 and a bump rod 513. The L-shaped telescopic rod 511 is fixed to the bottom of the T-shaped slide plate 52. The knocking rod 512 is fixed to the telescopic end of the L-shaped telescopic rod 511. One end of the knocking rod 512 away from the telescopic end of the L-shaped telescopic rod 511 contacts the bottom of the T-shaped slide plate 52. The bump rod 513 is fixed to the upper outer wall of the cooling tower body 1. A bump is fixed to the bottom of the bump rod 513. The bump of the bump rod 513 is located on the movement track of the telescopic end of the L-shaped telescopic rod 511. At the same time, the T-shaped slide plate 52 drives the L-shaped telescopic rod 511 to move. The bump of the bump rod 513 pushes the telescopic end of the L-shaped telescopic rod 511 to drive the knocking rod 512 to knock the T-shaped slide plate 52. The T-shaped slide plate 52 vibrates and drives the scraper 53 to vibrate, thereby improving the efficiency of the scraper 53 to scrape off the water vapor beads.

[0030] During use, due to the setting of the filter net 42, the filter net 42 intercepts the impurities contained in the water sprayed by the spray pipe 25, thereby avoiding the problem that the circulating pump 22 is easily blocked after inhaling impurities; at the same time, when the rotating rod 33 rotates, it drives the bump ring 411 to rotate. The bumps of the bump ring 411 push the arc-shaped rod 412 to drive the L-shaped rod 413 to move downward. The L-shaped rod 413 drives the impact rod 414 away from the circulation pipe 12. When the bumps of the bump ring 411 do not push the arc-shaped rod 412, under the elastic force of the elastic plate 43, the elastic plate 43 pushes the filter net 42 to drive the arc-shaped rod 412 to reset. The arc-shaped rod 412 drives the impact rod 414 to impact the circulation pipe 12. The circulation pipe 12 vibrates, and the circulation pipe 12 shakes off the scale adhering to the outer wall of the circulation pipe 12, thereby avoiding the problem that the heat exchange effect of the cooling tower body 1 decreases due to the formation of scale on the outside of the circulation pipe 12 by calcium, magnesium ions and acid hydrogen carbonates contained in the water.

[0031] At the same time, the strip groove plate 29 drives the T-shaped slide plate 52 to move synchronously. The T-shaped slide plate 52 drives the scraper 53 to scrape off the water vapor beads on the top inner wall of the cooling tower body 1. The scraped water falls back into the cooling tower body 1, thereby avoiding the problem that the water vapor column is blown and volatilized by the air flow generated by the fan assembly 11, resulting in damage and loss of the cooling water; at the same time, the T-shaped slide plate 52 drives the L-shaped telescopic rod 511 to move synchronously. The bump of the bump rod 513 pushes the telescopic end of the L-shaped telescopic rod 511 to drive the knocking rod 512 away from the T-shaped slide plate 52. When the bump of the bump rod 513 pushes the telescopic end of the L-shaped telescopic rod 511, under the elastic force of the L-shaped telescopic rod 511, the telescopic end of the L-shaped telescopic rod 511 resets and drives the knocking rod 512 to knock the T-shaped slide plate 52. The T-shaped slide plate 52 vibrates and drives the scraper 53 to vibrate, thereby improving the efficiency of the scraper 53 to scrape off the water vapor beads.
