Abstract: Backwash filters are mainly used to filter out mechanical debris from water, steam, and oil pipelines. The consultation hotline for Puhui backwash filters provides you with information on backwash filter size, pictures, introduction, price, and more.

II The main components and materials of the backwash filter are:

1. Take over, material Q235A;
2. Flanges, Q235A；
3. Ring plate, Q235A；
4. Hexagonal head bolt, 45;
5. Flanges, Q235A；
6. Sealing gasket, rubber or metal wrapped gasket;
7. Protective ring, SUS304；
8. Hexagonal nut, 35;
9. Flanges, Q235A；
10. Sewage pipes, Q235A；
11. Shell, Q235A；
12. Filter screen, SUS304；
13. Support plate, A3；
14. Reducing tube, Q235A。

III Working process of backwash filter:

Backwash filter, the medium flows in a large amount from the inlet direction (reducer end), passes through the mesh of the filter screen, and flows out of the entire filter chamber of the backwash filter. The debris is intercepted outside the filter screen, and after flowing water, the debris stays outside the filter screen for a short period of time. When discharging, the upstream valve is closed to backwash the filter screen. Close the downstream valve to flush the pipeline. The debris is discharged from the sewage outlet. When not discharging, flange blind plates or butterfly valves should be installed at the discharge outlet.
This backwash filter has a feature that can adapt to high temperature requirements compared to automatic sewage filters. Choose a metal wrapped gasket for the sealing gasket of the backwash filter.

Backwash filter image

These two pictures are physical images of the backwash filter DN100 1.6MPa. The flange facing the backwash filter on the left is the drain outlet. The drain outlet is set according to the size of the backwash filter body diameter, and the larger the specification diameter, the larger the drain outlet. The image on the right is a side view of the main body of the backwash filter. It can be clearly seen from the picture that the backwash filter main body can be divided into two parts, with the middle part being detachable and easy to maintain for long-term use, and large debris can be thoroughly cleaned. When we leave the factory, the backwash filter will indicate the most important parameters such as water flow direction, diameter, and pressure on the main body. The diameter of the main body cylinder in the middle of this filter is larger than the diameter of the inlet and outlet, so as to achieve the filter without reducing flow.

What is the temperature resistance of the high-temperature backwash filter

The operating temperature of the high-temperature backwash filter can be said to be the same as the temperature resistance of the shell material. Not only can it withstand temperature, but it can also be used in corrosive working conditions such as acid, alkali, and pin.
