Customized stock of rotary drum grille for papermaking

Customized stock of rotary drum grille for papermakingStructural features:

1. The grille and water flow form an angle of about 35 degrees, and due to the formation of a bend, even many pollutants with a thickness smaller than the grille gap can be separated.

2. The grille is equipped with a flushing device and has a self-cleaning function.

3. The cylindrical structure increases the water flow rate of the grille compared to traditional grilles, reduces head loss, and reduces the stacking plane in front of the grille.

4. All components in contact with water are made of stainless steel and undergo acid pickling and passivation treatment. They have strong anti-corrosion performance and long service life in all civil sewage and most industrial water.

5. By integrating the salvaging, conveying, and pressing of the grille, not only does it save floor space, but it also reduces the cost of subsequent garbage disposal. 6. Almost no maintenance is required, there is no need to add oil to the rotating point, and the driving device requires less refueling.

Customized stock of rotary drum grille for papermakingThe working principle mainly includes the following steps:

Inlet: The treated water flows through the drum shaped grille and enters the inlet tank.

Screening: After passing through the inlet tank, the water flows through the drum, which is filled with a series of evenly spaced screening plates. There are holes or gaps of a certain size on the sieve, which can screen out larger impurities and solid particles.

Solid separation: While the water flows through the sieve, solid particles are intercepted on the upper surface of the sieve, forming a solid particle layer to achieve preliminary separation of solids and liquids.

Cleaning: In order to ensure the normal operation of the rotary drum grille, it is necessary to regularly clean the screen pieces. Common cleaning methods include mechanical cleaning and water flushing cleaning.

Solid discharge: The cleaned solid particles are sent into the material box and then discharged through the solid discharge device.

Outlet water: After screening and solid separation, the water flows out through the hollow part of the drum and becomes purified water after treatment.
