Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of filters, in particular to a quartz sand filter. Background Art
[0002] The quartz sand filter is a common water treatment equipment, mainly used for water treatment and filtration in the home, commercial or industrial fields. It uses quartz sand as a filter medium to remove impurities such as suspended solids, silt, rust, chlorine, etc. in the water through the principle of physical filtration, thereby improving the quality and transparency of the water. Filter medium: Quartz sand is an ideal filter medium because it has hard and uniform particles that can effectively capture and filter impurities in the water. The particle size of quartz sand can be selected according to different application requirements. Filtration principle: When water passes through the quartz sand filter, it first passes through the pre-filter or directly enters the filter tank, and then gradually penetrates through the quartz sand layer. In this process, most of the suspended matter and solid particles are trapped by the quartz sand on the surface or in the deep filtration process. This physical filtration method can effectively remove particles and suspended matter with larger diameters. Cleaning and maintenance: As the use time increases, the quartz sand filter will gradually be blocked by impurities fixed in it, affecting its filtration efficiency. In order to maintain its performance, a post-flushing operation is required regularly to remove the blockage in the quartz sand layer and restore its filtration capacity. The post-flushing process flushes out the captured impurities by injecting water flow in the reverse direction of the filter. Application areas: Quartz sand filters are widely used in household tap water filtration, swimming pool water treatment, industrial process water filtration, drinking water treatment and other occasions. They can effectively remove sediment, suspended matter, chlorine, organic matter and some heavy metal ions in water, improve water quality, and protect the health of equipment and users. Design and selection: The design of quartz sand filters usually takes into account flow requirements, filtration accuracy requirements and equipment reliability. For large-scale industrial uses, multiple filter units in parallel or series may be required to meet the requirements of high flow and high-efficiency filtration. In short, as a simple and effective water treatment equipment, quartz sand filters improve water quality through physical filtration. They are widely used in various places where clean water sources are required and are one of the common water treatment solutions.
[0003] In the prior art, the quartz sand inside some quartz sand filters cannot be replaced, which weakens the internal filtering and capturing effect when filtering a certain amount of water, and even reduces its filtering effect, making the filtered water quality substandard. When filtering with some quartz sand filters, water flows directly to a location, causing the quartz sand at the location to escape to the surroundings, resulting in poor filtering effect at the location.
