Description

Technical Field

[0001] This utility model relates to the field of hydro-generator technology, specifically a water filter for a hydro-generator cooling system. Background Technology

[0002] During operation, hydro-generator units generate heat. The main heat-generating components are the stator, rotor, upper guide bearing, lower guide thrust bearing, and water guide bearing. The heat generated by these components is carried away by the heat exchanger of the unit using external cold water, so that the temperature of the unit is controlled within a certain range. The external cold water supply system is the cooling water supply system of the hydro-generator unit. During operation, the cooling water supply system of the hydro-generator unit requires the use of a water filter.

[0003] However, most of the filter elements in the water filters of current hydro-generator cooling systems are fixedly installed, making it impossible for people to replace and clean them. After long-term use, a large amount of impurities will remain on the surface of the filter element, thereby reducing the filtration efficiency of water and affecting the operation of the hydro-generator cooling system. Therefore, those skilled in the art have provided a water filter for hydro-generator cooling systems to solve the problems mentioned in the background art. Utility Model Content

[0024] Please see Figures 1-5In this embodiment of the present invention, a water filter for a hydro-generator cooling system includes a hydro-generator filter assembly 1, a cleaning assembly 2, and a cover plate 7. The hydro-generator filter assembly 1 includes a water filter tank 101, with annularly arranged support legs 12 mounted on the outer surface of the water filter tank 101. Each support leg 12 has a base 13 mounted on its outer surface. The outer surface of the water filter tank 101 is connected to a water inlet pipe 3, and a control valve 4 is mounted on the outer surface of the water inlet pipe 3. The outer surface of the water filter tank 101 is connected to a water outlet pipe 5. Both the outer surface of the water filter tank 101 and the outer surface of the cover plate 7 are provided with openings. The device has a ring of positioning holes 8, and each set of positioning holes 8 has a positioning screw 9 threadedly connected to its inner wall. This not only allows the equipment to automatically clean the filter screen 103, but also allows people to replace the filter screen 103. This solves the problem mentioned in the background art, where the filter elements in the water filters of the current hydro-generator cooling system are mostly fixedly installed, making it impossible for people to replace and clean them. After a long period of use, a large amount of impurities will remain on the surface of the filter element, thereby reducing the filtration efficiency of the water and affecting the operation of the hydro-generator cooling system.

[0025] The inner wall of the water filter tank 101 is equipped with a tray 102, and a filter screen 103 is placed on the upper surface of the tray 102. Two handles 104 are installed on the outer surface of the filter screen 103. The cleaning assembly 2 includes a bearing 201, which is embedded in the inner wall of the water filter tank 101. A rotating rod 202 is installed on the inner ring of the bearing 201. A fixing frame 203 is installed on the outer surface of the rotating rod 202. A cleaning strip 205 is installed on the outer surface of the fixing frame 203. The outer surface of the cleaning strip 205 is in contact with the filter screen 103, which not only makes it convenient for people to replace the filter screen 103, but also enables the equipment to automatically clean the filter screen 103.

[0026] A drive motor 204 is installed on the outer surface of the water filter tank 101. The output end of the drive motor 204 is connected to the rotating rod 202. A sealing gasket 14 is installed on the outer surface of the cover plate 7. A valve 6 is installed on the outer surface of the water outlet pipe 5. An observation window 10 is opened on the outer surface of the water filter tank 101. The inner wall of the observation window 10 is fitted with tempered glass 11, which not only makes the sealing effect of the equipment better, but also makes it convenient for people to check the status of the filter screen 103 inside the water filter tank 101.

[0027] The working principle of this utility model is as follows: First, the inlet pipe 3 and the outlet pipe 5 can be connected to the cooling system of the water turbine generator set. After the equipment has been working for a long time, the drive motor 204 can be started. The drive motor 204 can drive the fixed frame 203 and the cleaning strip 205 to rotate and clean the impurities on the surface of the filter screen 103. When the filter screen 103 needs to be replaced or repaired, the positioning screw 9 can be removed and the cover plate 7 can be removed. Then, the filter screen 103 can be taken out using the handle 104 for replacement or maintenance. During the operation of the equipment, the inside of the water filter tank 101 can be viewed through the tempered glass 11.
