Description

Technical Field

[0001] The utility model relates to the field of cooling towers in solar cell factories, in particular to an outlet water filtering device for cooling towers in solar cell factories. Background Art

[0002] The production process of solar photovoltaic cells has very high requirements for clean room temperature and humidity, and the chillers and air compressors in the power equipment need to be cooled, so the cooling water circulation volume is large and the number of supporting cooling equipment cooling towers is large. The water quality of cooling water is crucial to the operation of the equipment. If the impurities in the cooling water are not effectively filtered, the impurities in the cooling system will hinder heat transfer and water flow, thereby reducing the cooling effect. At the same time, impurities in the cooling system will also cause pipes, water pumps, cooling towers and other equipment to become blocked and corroded, reducing the operating efficiency and service life of the equipment, and even causing equipment failure.

[0003] The traditional cooling water filtering method is to install a Y-type filter on the cooling water pipe or install a fixed filter element on the water tray inside the cooling tower. During the filtering process, the filter element will intercept impurities in the water. As time goes by, the filter element will gradually become clogged, affecting the cooling effect of the cooling tower. Therefore, it is necessary to clean and replace the filter element regularly to ensure the normal operation and use effect of the cooling tower. The traditional cooling tower's fixed filter element can only be replaced after shutdown, and the installation of the filter element inside the cooling tower requires the height of the cooling tower's water tray to be increased, which has a high cost and cannot guarantee water quality efficiently, conveniently and at low cost. Therefore, an efficient, convenient and low-cost filtering device is needed. Utility Model Content

[0024] refer to Figure 1-Figure 2As shown, a water outlet filter device for a solar cell factory cooling tower provided in this embodiment is installed under the water receiving tray 2. To prevent the water outlet filter device 3 from being corroded and damaged, the water outlet filter device 3 is made of SUS304 stainless steel. The water outlet filter device 3 includes a filter box 31 and a filter element 32. The filter box 31 is a rectangular structure with an opening at the top, which is used to carry the filter element 32 to complete the filtering work. The top of the filter box 31 is connected to the bottom of the water receiving tray 2, so that cooling water can flow into the filter box 31. The bottom side is provided with a water outlet 33 for cooling water to flow out, and the filtered cooling water flows out from the water outlet 33. Three filter element installation ports 311 are sequentially arranged on the side wall of the filter box 31 from top to bottom. The shape and size of the filter element installation port 311 are adapted to the size of the filter element 32, ensuring that the filter element 32 can be firmly inserted into the filter element installation port 311. On the two inner walls of the filter box 31 adjacent to the filter element installation port 311, a hanging slide rail horizontal to the filter element installation port 311 is provided. After the filter element 32 is inserted into the filter element installation port 311, it is slidably connected to the inner wall of the filter box 31 through a hanging slide rail. The design of the hanging slide rail can be a single rail, a double rail or other forms, so as to meet the installation and disassembly requirements of different types of filter elements. The length of the slide rail can be set according to actual needs to meet different operating requirements. A handle 321 is provided on the front end surface of the filter element 32, which is convenient for the operator to hold the filter element 32, thereby sliding the filter element 32 on the hanging slide rail, and inserting or pulling out the filter element 32 from the slide rail, so as to easily complete the disassembly and replacement of the filter element 32.

[0025] refer to Figure 2-Figure 3 As shown, three layers of filter cartridges 32 are arranged in the filter box 31, which are arranged in sequence at three filter cartridge installation ports 311 on the side wall of the filter box 31. The top filter cartridge is a 20-mesh stainless steel wire skeleton coarse filter cartridge, which can remove large impurities and particulate matter. The middle filter cartridge is a 30-mesh stainless steel wire skeleton fine filter cartridge, which can continue to filter small impurities. The bottom filter cartridge can be selected from a 30-50-mesh stainless steel wire skeleton spare filter cartridge according to actual use. When one layer of the filter cartridge is blocked, the operator can pull out the filter cartridge in time, and the other two layers of the filter cartridges can continue filtering. The three layers of the filter cartridge can be flexibly switched according to actual conditions.

[0026] refer to Figure 2-Figure 3As shown, an inwardly inclined guide plate 35 is provided on the inner side of the filter element installation opening 311, and the width of the guide plate 35 is greater than or equal to the width of the filter element 32. An EPDM sealing strip is installed at the bottom of the guide plate 35, and the sealing strip extends to the filter element 32. The portion of the filter element 32 from the sealing strip to the filter element installation opening 311 is a watertight sealing area to prevent water from flowing out of the filter element installation opening 311, and the portion of the filter element 32 from the sealing strip to the end away from the filter element installation opening 311 is a filtering area. When cooling water enters from the upper part of the box body, the guide plate 35 guides the water to the filtering area above the filter element panel, ensuring smooth filtration of the cooling water while preventing water from flowing out of the filter element installation opening 311. The cooling water passes through the top filter element to remove larger impurities and particulates, and then passes through the middle filter element to continue filtering small impurities. If necessary, it can continue filtering through the bottom spare filter element according to the water quality. Finally, the cooling water flows out through the water outlet 33 to complete the cooling water filtration. When one of the filter elements is blocked and affects the water flow rate, the filter element can be directly pulled out through the handle 321. After a layer of filter elements is pulled out, other filter elements continue to work, which has no effect on water quality filtration and does not require shutdown. The operation is simple and convenient.

[0027] refer to Figure 2 As shown, a downward drain valve 34 is provided at the bottom of the filter box 31. The downward drain valve 34 provided at the bottom of the filter box 31 can play an important role when the outlet filter device 3 needs to be shut down for maintenance. Opening the drain valve 34 can release all the cooling water in the cooling tower 1, thereby helping to reduce the pressure in the cooling tower 1, facilitating maintenance and overhaul, and avoiding unexpected situations during maintenance. In addition, discharging cooling water also helps to reduce the burden on the filter element 32, making it easier to disassemble and repair.
