Description

Technical Field

[0001] The utility model relates to the technical field of cooling tower water collecting tanks, in particular to a water leakage-proof closed cooling tower water collecting tank. Background Art

[0002] The working principle of a closed cooling tower is to circulate the working fluid (pure water or other liquid) in the coil of the closed cooling tower. The heat of the working fluid is dissipated through the coil into the spray water flowing through the outer surface of the coil. At the same time, the air outside the unit enters from the air inlet grille on the chassis, in the opposite direction of the water flow, and flows upward through the coil. A small part of the water evaporates and absorbs heat. The hot and humid air is discharged into the atmosphere by the fan at the top of the cooling tower. The rest of the spray water falls into the bottom water tray, which is recirculated by the spray pump to the water distribution system and then back to the coil. The water collection tank is an important component of the closed cooling tower.

[0003] The bends between the joints of the traditional water collecting tank plates need to be fixed with bolts and sealed with sealing strips. Therefore, it is inevitable that the bolts will turn the sealing strips into many holes. These bolt holes are often the fault points that are prone to leakage. Therefore, a water-leakage-proof closed cooling tower water collecting tank is proposed. Utility Model Content

The end of the screw 8 extends to the outside of the fixed plate 5 and is connected with an adjustment disk 7. The screw 8 is sleeved with a screw sleeve 4. After the adjustment disk 7 rotates, the screw 8 is driven. The adjustment disk 7 can be replaced by a motor to achieve electric adjustment. The lower end of the screw sleeve 4 is installed with a connecting rod 6, the end of the connecting rod 6 passes through the slide groove 9 and is connected with the scraper 3, the bottom and side wall of the scraper 3 are respectively connected with the inner bottom and inner side wall of the water collecting tank 1, the screw sleeve 4 is affected by the rotating thread of the screw 8 to produce horizontal movement, and the screw sleeve 4 moves and drives the scraper 3 through the connecting rod 6, and the scraper 3 cleans the water collecting tank 1.

[0023] Working principle: The side panels 10 and the bottom panel 11 are bent twice at their edges during processing to form screw hole surfaces 13 and sealing surfaces 14. The screw hole surfaces 13 between adjacent side panels 10 and bottom panels 11 fit together and are fixed with bolts. Sealing adhesive is applied for sealing.
