Description

Technical Field

[0001] The utility model relates to the technical field of backwashing equipment, in particular to a water-saving backwashing device for a filter tank. Background Art

[0002] A filter tank is a device used for water treatment and sewage treatment. Its main function is to remove impurities, particulate matter and pollutants in water through filter media, thereby providing a clean water source. Filter tanks are usually used in water purification, swimming pool water treatment, industrial wastewater treatment and other fields. The filter bed is the core part of the filter tank and is composed of one or more filter materials, such as sand, gravel, coal, activated carbon, glass fiber, etc. When water flows through the filter bed, the impurities, particulate matter and pollutants are retained in the filter media, while clean water flows out through the filter bed. The working principle of the filter tank is to remove impurities and particulate matter in the water through the physical interception effect of the filter bed. When water flows through the filter bed, larger particles will be retained on the surface by the filter media, while smaller particles will pass through the gaps in the filter media. Over time, more and more dirt gradually accumulates on the surface of the filter media, affecting the filtration efficiency of the filter media. Therefore, regular backwashing is necessary to clean the surface of the filter media and restore its filtration capacity.

[0003] A conventional filter backwashing device is usually used to apply pressure or water flow to the filter to clean dirt on the surface of the filter material. The backwashing device usually includes a nozzle, a spray head or a jet pipe, which can generate a high-pressure water flow to wash out the dirt accumulated on the filter material.

[0004] However, the traditional filter backwashing device uses multiple valves to control each pipeline, which may make it difficult to coordinate and adjust the actions between the valves. If the operation between the valves is not synchronized or coordinated, it may cause system problems such as uneven water flow or unstable pressure. Therefore, a filter water-saving backwashing device is proposed to solve the above problems. Utility Model Content
