A method for making a water filter that is easier to clean

　　Currently, coal-fired power generation mainly relies on the combustion of coal in boilers to heat water into high-temperature and high-pressure steam. The high-temperature and high-pressure steam does work in the steam turbine, thereby driving the generator to generate electricity. To ensure that no toxic and harmful substances are produced when the water is heated, it is usually necessary to filter the water before heating. Currently, Water filter Comet-type fiber filter media are usually used to filter impurities, but the comet-type fiber filter media often break and float on the water distributor during backwashing operation, thereby blocking the water inlet of the water distributor, increasing the water inlet resistance, which is not conducive to water inlet and also affects the washing effect. At the same time, the broken fibers will also block the exhaust holes, causing inconsistent internal and external air pressure of the filter, affecting the water output. Water filter

　　In order to overcome the shortcomings of the existing technology, technicians provide a water filter with a better washing effect. It adopts the following technical scheme: The water filter includes a shell, a water distribution component and an exhaust component installed on the top of the shell, a comet-type fiber filter layer and a quartz sand filter layer contained in the shell, and the comet-type fiber filter layer is located above the quartz sand filter layer. The water distribution component includes an inlet pipe rotatably inserted into the shell, a water distribution bucket connected to the inlet pipe, a cleaning component set on the side of the water distribution bucket, and a driving component for driving the inlet pipe to rotate. The water distribution bucket is provided with through holes, and the cleaning component is provided with bristles, and the bristles are in contact with the water distribution bucket; water filter

　　Among them, the water distribution bucket and the cleaning component are both contained in the shell. The water distribution bucket has a hollow cylindrical structure. The side wall and bottom wall of the water distribution bucket are provided with through holes. The cleaning component includes longitudinally connected longitudinal rods and transverse rods. The bristles are set on the side of the longitudinal rods and transverse rods close to the water distribution bucket. The filter strip includes interconnected ventilation segments and sealing segments. The filter holes are set on the ventilation segments. By moving the filter strip, the ventilation segments or sealing segments can be fitted to the lower end face of the exhaust pipe. The driving part includes a motor installed on the shell, an active gear installed on the output shaft of the motor, and a driven gear installed outside the inlet pipe. The driven gear meshes with the active gear. The upper end of the shell is provided with an inlet and an outlet. The lower end of the inlet pipe extends into the shell after passing through the inlet, and the lower end of the exhaust pipe extends into the shell after passing through the outlet. A filter screen is provided on the outer shell corresponding to the air inlet and outlet. The shell includes a body and a cover set on the top of the body, and the inlet pipe and the exhaust pipe are both set on the cover. A sealing element is sandwiched between the inlet pipe and the cover. The lower end of the body is provided with a plurality of support feet. The compression cylinder is a cylinder. Water filter

　　The advantages of this new type of water filter are: By setting the cleaning component, the fibers on the surface of the water distribution bucket can be cleaned when the water distribution bucket rotates, preventing the increase of water inlet resistance; in addition, by moving the filter strip, different parts of the filter strip are attached to the exhaust pipe, preventing the exhaust pipe from being blocked by fibers, maintaining consistent internal and external air pressure of the shell, and water can flow out smoothly during exhaust, the operation is simple, and it has good market promotion ability.
