Description

Technical Field

[0001] The utility model relates to the technical field of water treatment equipment, in particular to a quartz sand filter with a filter element that is easy to replace. Background Art

[0002] The quartz sand filter is a water treatment device that uses quartz sand as a filter medium. Under a certain pressure, it can filter water with high turbidity through a certain thickness of granular or non-granular quartz sand, which can effectively intercept and remove suspended matter in the water. It has the advantages of fast filtration speed, high filtration accuracy, and large pollution interception capacity. However, the service life of quartz sand filter material is greatly affected by water quality. When the water quality is poor, it is easy to be contaminated. Once contaminated, the filter material needs to be replaced in time. In order not to affect the processing progress and improve work efficiency, a quartz sand filter that is easy to replace the filter element is proposed.

[0003] According to the search, Chinese patent literature, announcement number: CN213313622U, discloses a quartz sand filter that is easy to replace the filter element. By turning off the electromagnet, the cylinder raises the sealing cover, separates the push plate from the sealing cover, takes out the sealing cover and the connecting frame at the same time, removes the positioning plate on the top of the chimeric frame, replaces the filter element, and then installs it. However, when the filter element needs to be replaced during actual use, the connector, sealing cover, positioning plate and other parts need to be removed in sequence before replacement, and the connector and the water inlet channel are still flange-connected, so it is inconvenient to disassemble and assemble, which reduces the overall work efficiency of the device; in addition, when a certain amount of impurities exist in the filter element, the device cannot be cleaned in time, which not only affects the filtration efficiency, but also reduces the service life of the filter element, and the staff can only disassemble it for maintenance, which reduces the overall practicality of the device.
