Rotary filters. A brief overwiew.

Rotary filters are designed for separation of suspensions containing large particles. They are also used when a long and thorough cake washing is required.

These filters consist of a series of Nutsche filters moving around a circle in a horizontal plane. Nutsche filters have rubber lattice bottoms with a filter cloth and are hinged to a horizontally rotating circular frame.

The rotary filter has a four-compartment distribution head for connection to the vacuum line, compressed air line and wash liquid line. The head is connected to all Nutsche filters with a flexible hose. As the frame rotates, each Nutsche filter is filled with the suspension and is connected to the vacuum line. Once the filtrate is separated, the cake is washed and blown with air. Then, the Nutsche filter is removed and the cake is discharged into the receiver, and the filter material is cleaned from the remaining solid phase and dried. Then, the Nutsche filter is placed in its original position and the filtration is repeated. The area of the working surface of the rotary filter can reach 1.0-60 m2.

This filter has all the advantages of Nutsche filters, while being a continuous unit. It is a set of horizontal Nutsche filter placed around a circle and connected by flexible hoses equipped with switchgears similar to those used in disk and drum filters. As the frame used to support Nutsche filters rotates, all Nutsche filters are filled, in series, with the suspension. Then, the cake is washed, dried and removed, and the filter cloth is washed and dried. The corresponding Nutsche filter is turned upside down during cake removal. After the filter cloth is washed, the Nutsche filter is placed in its original position.

Advantages of rotary filters include thorough washing of the cake, long life of the filter cloth and matching of settling and filtration directions.

The main feature of rotary vacuum filters is a circular horizontal filtering surface. It is formed by interconnected special buckets connected to the distribution head chambers wherefrom they scoop the cake and then are emptied in the place of discharge.

The operating surface of the filter usually consists of a few dozens of trapezoid buckets which move around the vertical filter axis together with the moving frame. The buckets are mounted in bearings. The moving frame is driven by special rollers mounted on a stationary base. This base is also used as a support for the distribution head, rails, suspension feeding system, drive elements, etc.

The frame drive is usually located one floor below because it is less exposed to sprays and vapors from the treated suspensions. The drive design includes a motor, a chain variable-speed gear, a gearbox (cylinder and cylinder-conic), a shaft and a drive gear. A toothed rim is attached to the moving frame by means of an internal toothing.

The bucket is a welded structure with a tube welded to its side wall. A rubber hose is attached thereto to connect the bucket to a cell gasket. A rubber mat is used as a drainage base. The filter membrane (cloth) is fixed along the bucket perimeter with special metal bars and screw clamps.

Filter operating cycle

The filter operating cycle can be divided into the following stages: feeding of the suspension into the bucket, filtration and repeated washing, drying and removing of the resulting cake, washing and drying of the filter cloth.

Continuous feeding of suspension and wash liquid into buckets is possible due to special trays located above the rotary carousel. The remaining matter formed during filtration is supplied into the vacuum chamber of the bucket and then it is discharged from the filter through the distribution head.

Having reached the discharge area, the bucket is automatically turned over, and the cake is discharged into the hopper due to gravity and compressed air. Then, the bucket is washed in a special collector where the wash liquid is pressurized upwards to clean the filter cloth. Then, the cloth is dried and the bucket takes its initial position to repeat the cycle.

Rails are used to prevent bucket overturning during operation (because its center of gravity is above the axis of rotation). A special rigidly fixed lever with rollers at its ends is used to control the bucket turning time. Each lever roller moves along its own guiding rail. Once the level of guiding rails changes or they are separated, the bucket turns over. This is necessary for the cake discharge. After the filter cloth is dried, the rails return the bucket to its initial position.

Applications

These filters are used in the following cases:

  • when separated suspension which required rapid separation contains dispersed-phase solids of different size;
  • when thorough cake washing is required.
