Water Purifier Sand Filter Nozzles

Umbrella Drain Cap Sand Filter Nozzles With Long Handle / Short Handle

The filter head material is made of ABS engineering plastics, which has high pressure bearing strength and can't be broken when being stepped on. In the filter head structure, the thread is strengthened, and the rubber washer is added, which is connected firmly and never falls off. The base of the filter head cap is designed to enhance the bottom seam, so that there is no dead water area and mud deposition between the filter plate. Widely used in water treatment filter, filter, softened water combination, return program, ion exchange column equipment. All kinds of filter caps are suitable for all kinds of matching ion exchange columns, active carbon filters, and drainage system of fast filter.

Working Principle

Working principle of backwashing: the arc surface of the filter cap of the filter head is evenly opened with long and carefully processed fine seams, which can not only prevent the leakage of the filter material, but also ensure the uniform distribution of gas and water. The filter rod is a plastic pipe with a small hole at the top and two air inlet slits near the bottom. After the space under the compressed air filter plate is formed, the air layer is gradually thickened, and the water under the air layer is constantly falling until the water surface falls to the long air inlet slits at the bottom of the filter rod, at this time, the air begins to flow into the filter rod from the slits. When the air flow in is equal to the flow through the gap of the filter cap, the water surface will stop falling, and the air stabilized in the first place will rise through the gap of the filter cap and go to the filter material layer through the gap of the filter cap. Due to the cross and uniform distribution of multiple filter heads, good backwashing effect will be achieved. Note (generally, if the backwash water sump becomes clear, the backwash can be stopped to control the unnecessary loss of the backwash water).

Application

The long handle filter head is applied to the air-water backwash water distribution system of the filter; the short handle filter head is applied to the single water backwash of the filter and the water distribution and filtration systems such as gravity type, pressure type filter tank and ion exchange filter bed. The filter head can be used not only for drinking water treatment, but also for beverage, printing and dyeing, swimming pool and other industrial water places. It can also be used in industrial wastewater and domestic sewage treatment projects.

1. High pressure bearing strength, hard to break

2. Table strengthen thread, add rubber washer, connect firmly

3. The filter head cap base is designed to enhance the bottom seam, which is not easy to change

4. There is no dead water area between plates, which is not easy to deposit mud and has good effect

5. Mechanical assembly, high performance

6. Solid overall strength, long service life
