Pressurized disc filter

Abstract

The invention relates to solid-liquid separation filtering equipment, especially to a pressurization disc-tilting filter. The pressurization disc-tilting filter mainly overcomes the technical problems like that a conventional continuous pressurization filter can hardly meet requirements for continuous procedures of filtering, washing, discharging and filter cloth regeneration. The pressurization disc-tilting filter provided by the invention comprises a pressure tank. The pressure tank is connected with an air pipe, and the bottom of the pressure tank is provided with a rotating mechanism; a dry slag hopper and a wet slag hopper are arranged below the rotating mechanism; the dry slag hopper is connected with a sealed discharger; the center position of the filter is provided with a distribution head; the rotating mechanism is connected with a plurality of ladder-shaped filter discs, and the ladder-shaped filter discs mutually overlap to form a circular ring; a big end of each ladder-shaped filter disc is provided with a disc tilting fork; a curve track is arranged on the inner wall of the pressure tank; rollers of the disc tilting forks are located on the curve track; a hollow shaft of a small end of each ladder-shaped filter disc is connected with the distribution head; a frame is arranged at the bottom of the filter; and a loading hopper and a washing hopper are respectively arranged above the ladder-shaped filter discs and are respectively connected with a force pump.

Description

technical field [0001] The invention relates to a filter, in particular to a pressurized flip filter. Background technique [0002] With the needs of various domestic industries for new process research and development and process technical transformation, the requirement for continuous operation as a core solid-liquid separation unit is more urgent. At present, vacuum-powered filters are widely used in the production process of various industries. Usually, the filter power is less than 0.06MPa due to the influence of vacuum, which makes the moisture content of the filter cake higher. The equipment needs to be used in conjunction with multiple sets of gas-liquid separation. The filter discharges the filtrate, which requires installation height or adopts multiple sets of vacuum automatic draining devices, and cannot be used for materials with high filter cake filtration resistance, as well as filtration and separation of oxidants, toxic and harmful substances, and flammable a...

Problems solved by technology

At present, vacuum-powered filters are widely used in the production process of various industries. Usually, the filter power is less than 0.06MPa due to the influence of vacuum, which makes the moisture content of the filter cake higher. The equipment needs to be used in conjunction with multiple sets of gas-liquid separation. The filter discharges the filtrate, which requires installation height or adopts multiple sets of vacuum automatic draining devices, and cannot be used for materials with high filter cake filtration resistance, as well as filtration and separation of oxidants, toxic and harmful substances, and flammable and explosive substances; Intermittent operation filters that use positive pressure as the filtering power, such as plate and frame filters, are still widely used. When positive pressure is used as the driving force, the general pressure difference can reach 0.2-0.6MPa, which is 3-10 times that of vacuum, but continuous It is difficult for a press filter to meet the continuous process requirements of filtration, washing, unloading, and filter cloth regeneration.
