Description

Technical Field

[0001] The utility model relates to the field of filter screens, in particular to a hydraulic structure of an ultra-deep rotary filter screen. Background Art

[0002] A rotary filter is a commonly used solid-liquid separation device in water treatment, primarily used to intercept and remove smaller suspended solids and particulate matter from water supply systems. It is commonly used in water supply projects such as surface waterworks. It can also be used in drainage treatment projects to further remove contaminants after the coarse screen. Rotary filters are primarily used for filtering and cleaning water before it is drawn by DC water pumps in thermal power plants. They effectively intercept and remove aquatic plants, industrial, agricultural, and domestic waste, organic floating debris, and fish and shrimp from the water. This equipment is designed to improve water cleanliness and ensure the safe and economic operation of power plants. Besides thermal power plants, rotary filters are also widely used in industries such as municipal water supply, chemical industry, metallurgy, and nuclear power plants, as well as in municipal sewage treatment. The rotary filter's structural features include a transmission mechanism, safety devices, a sprocket drive system, an upper frame steel structure and housing, and a flushing water system. Among its design features, the large housing, which used for side water inlet, is now housed within the frame bearings, shielding them from water and facilitating rust prevention. The longitudinal seal between the screens has been changed from the traditional overlapping type to a mechanical arc meshing method, and fully sealed operation is adopted to completely eliminate short-circuiting of waste, all of which are designed to improve the reliability and efficiency of the equipment. Furthermore, the rotating screen, used in conjunction with an upstream trash rack, effectively intercepts and removes all types of waterborne debris, including aquatic plants, leaves, branches, fish and shrimp, as well as waste generated during industrial, agricultural, and municipal sewage treatment processes. The widespread use of this equipment ensures the safe and economical operation of power plants and other fields, while also meeting the high water quality demands of modern industrial and urban development. Existing technology intercepts debris larger than the screen gap as wastewater flows through. During operation, the screen continuously rotates, lifting trapped debris to the top. Pressurized water then flushes the debris into a receiving trough for further processing. However, existing technology often damages the screen in water sources with high levels of debris, resulting in a reduction in filtration capacity. Furthermore, the screen design is not compact, and it can fall off at high speeds. Therefore, those skilled in the art provide a hydraulic structure of an ultra-deep rotary filter to solve the problems raised in the above background technology. Utility Model Content
