Abstract

The invention discloses a self-healing filter cap of a sand filter and a mounting and using method of the filter cap. The filter cap comprises a filter bearing assembly, a water and air part and a self-healing fastening part, wherein the filter bearing assembly is used for bearing granular filter materials and allowing clear water to pass; the water and air part is used for guiding filtered waterto a filter plate and allowing backwash water and compressed air to pass; the self-healing fastening part is used for fastening and connecting the filter plate and filtering the filter materials secondarily; the filter bearing assembly is connected with the self-healing fastening part through the water and air part. With application of the self-healing filter cap of the sand filter, damage to mainline equipment by the fact that the granular filter materials in the sand filter enter a circulating water system can be avoided to the greatest extent, and influence on product quality is avoided.

Description

technical field [0001] The invention belongs to the technical field of sand filters, and in particular relates to a filter cap of a self-healing sand filter and an installation and use method thereof. Background technique [0002] The sand filter is a professional water purification device that filters sewage through its own granular filter material, removes impurities in the water, and purifies the sewage. The filter cap is a water distribution system at the bottom of the sand filter and an air-water backwashing device, which can effectively flush Remove sludge and other sundries in the sand filter to ensure the normal operation of the water quality and quantity of the sand filter. However, due to the influence of many factors in the process of installation and use, the filter cap will be damaged, causing the particulate filter material to enter the filtered water, affecting the equipment that uses the filtered water, and even blocking the pipeline, affecting the circulatin...
