Suctorial Type Backwash Self Cleaning Filter

Product Brief Description

Thesuction backwash filteris an industrial automatic filter that provides a variety of comprehensive applications, especially for ships and offshore platforms. The suction backwash filter can have a different number of filter elements in each filter to provide a larger filter area. This allows the filter to be used with minimal pressure loss. The filter provides automatic, backflush cleaning operations and can continuously separate impurities from water and other liquids. The suction backwash filter is easy to maintain and operate and maintains good operating conditions even under harsh operating conditions.

Product Details (Core Parts)

Product Features:

The design of the pressure in the main part of the filter is usually based on the standard design of chemical pipe filters and steel pressure vessels. Filters can also meet the special requirements of other design standards. The main body of the equipment is made of carbon steel, stainless steel, duplex steel and other materials. We can also provide you with titanium, pure nickel and other special materials.

Product working principle

The sewage to be filtered enters the shell from the lower part of the filter, enters the inner cavity of the filter element from the bottom to the top, and then flows out through the filter element. After filtering, the purified water flows out through the outlet at the upper part of the filter, and the solid impurities are trapped inside the filter element. When the filter element is backflushed, it is not necessary to cut off the water inflow. The motor drives the filter element suction cup to rotate while opening the backflush blowdown valve. Each filter element is backwashed with filtered water.

As a result of the differential pressure between the water pressure and atmospheric pressure in the filter, the filtrate flows backwards to remove the impurities trapped on the inner wall of the filter element. After one revolution of the suction cup, the recoil ends. The recoil valve closes and the drive motor stops.

Product Advantage

Thesuction backwash filteradopts multi-layer mesh filter element structure, which can maximize the effective filtering area; the high-efficiency backwash technology, combined with the laser welding technology, the filter is especially suitable for the sea and ships.

In addition to satisfying the flow rate of normal design, a set of the sparefilter elementsis added. When cleaning is required, the spare filter element is started, so it will not affect the pipe resistance. The cleaning assembly is in the form of sucking up and down, which maximizes the cleaning of impurities in the shortest time.

Clean the gasket at the rotating shaft and filter element faceplate, and have automatic adjustment function according to the wear, so as to minimize the side leakage.
