Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically to a cooling tower with a cleaning function. Background Technology

[0002] Cooling towers are devices used to cool circulating water and are widely used in power plants, petrochemical plants, and consumer goods industries. Their main principle is to cool the incoming water through heat exchange or heat conduction.

[0003] A search revealed that Chinese patent application CN202320168573.X proposes an environmentally friendly cooling tower for wastewater treatment with self-cleaning function. The cooling tower includes a tower body and a water collection box. The tower body has an air outlet, and a first motor is installed inside the air outlet. An exhaust fan is mounted on the output shaft of the first motor. A water distributor is installed inside the tower body. Packing material is installed inside the tower body. A second motor is installed on the bottom surface of the water collection box, and a sleeve is fitted onto the output shaft of the second motor. A brush roller is installed inside the water collection box, and a connecting rod is installed on the sleeve. A gear is connected to one end of the brush roller, and a toothed ring is installed on the side wall of the water collection box. A brush is installed at the lower end of the connecting rod, and a water outlet is provided on the bottom surface of the water collection box. In the above-mentioned prior art, the main method is to use a motor to drive the sleeve and connecting rod to rotate, and then use the brush carried on the connecting rod to clean the inner wall and bottom of the lower end of the cooling tower, thereby reducing the scale and other deposits on the inner wall of the cooling tower.

[0004] In the aforementioned prior art, a motor is mainly used to drive a sleeve to rotate, which in turn drives the cleaning brushes at both ends to rotate. Rolling gears installed at both ends of the sleeve mesh with a gear ring installed on the inner side of the lower end of the cooling tower, thereby causing the rolling gears to drive the rotating brush to rotate. The rotating brush then cleans the scale and other deposits adhering to the inner wall of the cooling tower. Although this cleaning method can remove scale and other deposits from the inner wall of the cooling tower, during the cleaning process, on the one hand, the meshing point between the gears and the gear ring is easily jammed by scale, causing damage to the gears or gear ring and reducing the service life of the cleaning structure. On the other hand, the scale that is washed off can easily mix into the cooled water, requiring subsequent filtration and adding processing steps. Utility Model Content

[0005] The purpose of this invention is to provide a cooling tower with a cleaning function, which solves the problems in the prior art where the service life of the cleaning structure is reduced due to scale during internal cleaning of the cooling tower, and it is inconvenient to screen and process the scale that falls off during cleaning.

[0010] As a preferred embodiment of the above technical solution, a plug rod is fixedly connected to the lower side of the rotating shaft, and a clamping plate is fixedly connected to both ends of the plug rod.

[0011] The above technical solution utilizes the insertion rod and clamping plate to position the sleeve rod during installation, and allows the sleeve rod and threaded propeller to rotate when the shaft rotates subsequently.

[0012] As a preferred embodiment of the above technical solution, a filter assembly is provided on the outside of the insertion rod, and the filter assembly includes the insertion rod and a sleeve rod sleeved on the outside of the card plate, and a threaded paddle is fixedly connected to the outside of the sleeve rod.

[0013] The above technical solution uses the rotation of the threaded paddle to stir the impurities and scale stored in the sleeve, thus preventing the impurities and scale from clogging the filter screen.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] like Figure 1 - Figure 7 As shown, this utility model provides a technical solution: a cooling tower with a cleaning function, including a tower body 1, a control box 11 fixedly connected to the outer side of the upper end of the tower body 1, and a heat dissipation vent 12 fixedly connected to the upper side of the tower body 1. A water inlet 13 is fixedly connected to the end of the tower body 1 away from the control box 11, and a drain outlet 14 is fixedly connected to the middle of the lower side of the tower body 1. A cleaning assembly 2 is fixedly connected to the inner side of the heat dissipation vent 12, and the cleaning assembly 2 includes a dual-axis motor 21 fixedly connected to the inner side of the lower end of the heat dissipation vent 12. The upper end of the dual-axis motor 21... The output shaft is fixedly connected to the fan blade 22, and the lower end of the output shaft of the fan blade 22 is fixedly connected to the rotating shaft 23. The upper end of the rotating shaft 23 is rotatably connected to the heat dissipation port 12, and the outer side of the upper end of the rotating shaft 23 is fixedly connected to the filter screen umbrella 24. The cleaning component 2 and the filter component 3 can be used to clean the scale and other substances attached to the inner side of the lower end of the tower body 1. The scale after cleaning can also reduce the impact of the cleaning component 2 and the filter component 3. At the same time, the scale that is washed off and the impurities in the water are filtered and collected for subsequent treatment.

[0030] like Figure 3 and Figure 4 As shown, a connecting plate 25 is fixedly connected to the outer side of the lower end of the rotating shaft 23, and a first cleaning brush 26 is fixedly connected to the end of the connecting plate 25 away from the rotating shaft 23. A second cleaning brush 27 is fixedly connected to the lower end of the connecting plate 25. The rotating shaft 23 drives the connecting plate 25 to rotate, and then the connecting plate 25 drives the first cleaning brush 26 and the second cleaning brush 27 to rotate, thereby using the rotation of the first cleaning brush 26 and the second cleaning brush 27 to clean the inner wall and bottom of the lower end of the tower body 1.

[0031] like Figure 5 As shown, a plug rod 28 is fixedly connected to the lower side of the rotating shaft 23, and a clamping plate 29 is fixedly connected to both ends of the plug rod 28. The plug rod 28 and the clamping plate 29 are used to position the sleeve rod 31 for installation, and at the same time, they can drive the sleeve rod 31 and the threaded propeller 32 to rotate.

[0032] like Figure 5 As shown, a filter assembly 3 is provided on the outside of the insertion rod 28, and the filter assembly 3 includes the insertion rod 28 and a sleeve rod 31 sleeved on the outside of the clamping plate 29. A threaded paddle 32 is fixedly connected to the outside of the sleeve rod 31. The sleeve rod 31 drives the threaded paddle 32 to rotate, thereby using the rotation of the threaded paddle 32 to agitate the impurities and scale on the upper side of the filter screen plate 33, so as to prevent the impurities and scale from clogging the filter screen plate 33.

[0033] like Figure 3 and Figure 4 As shown, a filter screen plate 33 is rotatably connected to the lower end of the sleeve rod 31, and a sleeve 34 is fixedly connected to the outside of the filter screen plate 33. The upper end of the sleeve 34 is inserted into the drain outlet 14. The filter screen plate 33 is used to filter the impurities carried in the discharged sewage and the scale that is washed off, while the sleeve 34 is used to collect the impurities and scale at the filter.

[0034] like Figure 6 and Figure 7 As shown, a locking block 35 is inserted into the inner side of the upper end of the sleeve 34, and a pull rod 36 is fixedly connected to the end of the locking block 35 away from the sleeve 34. A handle 37 is fixedly connected to the end of the pull rod 36 away from the locking block 35, and springs 38 are fixedly connected to both ends of the pull rod 36 near the locking block 35. The end of the spring 38 away from the pull rod 36 is fixedly connected to the drain outlet 14. By using the elastic potential energy of the spring 38 to push the pull rod 36 and the locking block 35, the locking block 35 can be inserted into the sleeve 34 to lock and fix it.

[0035] Working principle: When using a cooling tower to cool wastewater, the dual-shaft motor 21 is started first. After the dual-shaft motor 21 starts, the output shafts at both ends simultaneously drive the fan blades 22 and the rotating shaft 23 to rotate. After the fan blades 22 rotate, they draw air from inside the tower body 1. The air inside the tower body 1 is drawn out and discharged from the heat dissipation port 12. At this time, the outside air enters through the slots opened at the upper end of the tower body 1, thus forming an air circulation. After the rotating shaft 23 rotates, it drives the filter screen umbrella 24 and the connecting plate 25 to rotate. At the same time, the rotation of the connecting plate 25 drives the first cleaning brush 26 and the second cleaning brush 27 to rotate. The first cleaning brush 26... The rotation of the second cleaning brush 27 cleans the inner wall and bottom of the tower body 1. Simultaneously, the rotating shaft 23 drives the sleeve rod 31 and threaded paddle 32 to rotate via the insert rod 28 and the clamping plate 29. The wastewater to be treated is then injected into the tower body 1 through the inlet 13. After injection, the wastewater impacts the filter screen 24, which, through its rotation and perforations, disperses and filters the wastewater, allowing heat to dissipate quickly. Simultaneously, the dispersed wastewater drips down the inner wall of the tower body 1 or passes through the middle of the filter screen 24 and falls to the bottom of the tower body 1. The wastewater is then discharged through the drain outlet 14. After falling onto the filter screen 33, the water is filtered and discharged. Impurities and scale remain on the upper side of the filter screen 33. At this time, the rotation of the threaded paddle 32 can be used to keep it in motion, thus preventing blockage of the filter screen 33 and preventing water from passing through. When it is necessary to clean the impurities stored in the sleeve 34, first pull the handles 37 at both ends to move the pull rod 36 and the locking block 35 to move the tension spring 38. After pulling the locking block 35 out of the sleeve 34, hold the sleeve 34 to pull it out of the drain outlet 14. After the sleeve 34 is pulled out of the drain outlet 14, it will also move the sleeve. After the rod 31 is disengaged from the insert rod 28 and the clamping plate 29, the sleeve 34 is removed and the impurities and scale collected inside are cleaned. After cleaning, the sleeve 34 is inserted into the drain outlet 14 along with the sleeve rod 31. The sleeve rod 31 is inserted with the help of the positioning of the insert rod 28 and the clamping plate 29. When the sleeve 34 is inserted, it squeezes the clamping blocks 35 at both ends inside the drain outlet 14. After the clamping blocks 35 are squeezed, they push the pull rod 36 to stretch the spring 38. After the sleeve 34 is inserted, the elastic potential energy of the spring 38 pushes the clamping blocks 35 back to their original position, so that it can be inserted into the sleeve 34 for locking and fixing.

[0036] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
