The exterior surface of the drum consists of a sheet of stainless steel with very fine perforation, covering all section of the drumĪs the Vacuum Filter rotates, the section which first enters the liquid is immediately connected with the low vacuum.
The third connecting to a chamber where a higher vacuum is maintained. The second communicating with a chamber where a low vacuum in maintained. One without connecting to the vacuum, but connected to the atmosphere. Each of the section is connected individually to vacuum system by a small metal pipe terminating in a distributing valve suited at one end of the drum and carrying three different sectors: The periphery of the drum serves as the filtering surface it is divided into numbers of independent section. The filter is composed of a hollow drum rotating about a horizontal axis and partly submerged in the liquid to be filtered. Fabricated by the professionals by using advanced technology, these filters are primarily used in sugar industry for filtration of muddy juice. Offered Rotary Vacuum Filters are manufactured by making use of the quality-assured raw material, sourced from the most prestigious vendors of the industry. All solvent and gas streams can be recovered separately and reused in the process to minimize their consumption.We are a leading name in this domain engaged in manufacturing and supplying a broad array of Rotary Vacuum Filter. After automatic cake discharge, the filter cloth is washed the clean filter cloth then re-enters the feeding / filtration zone thereby continuing the process. The Filter has a uniquely designed discharge system, which provides for atmospheric discharge from pressure filtration. Finally, the cake is dried by blowing hot or ambient-temperature gas through the cake. Multiple washing steps as well as solvent exchanges, steaming and extraction can also be accomplished.
Positive displacement washing or counter-current washing follows filtration. The technology is based upon a slowly rotating drum, less than 2 rpm, with individual cells containing the filter media and isolated process zones.įiltration is driven by pump pressure of up to 7 barg with a temperature range of 200° Celsius. The BHS Rotary Pressure Filter is a continuously operating filter for pressure filtration, cake washing and drying of high solids slurries with full containment and automatic cake discharge.
