摘要： A method of recovering a crystal component, in which without circulatory use of a filtrate or washing filtrate as a washing liquid and without circulatory use thereof in re-slurrying of crystal component, a reaction solvent can be efficiently removed from the crystal component; and a relevant crystal component recovering system. There is provided a method of recovering a crystal component, comprising the steps of feeding a crystal-component-containing slurry produced by reactor (50) into first rotary filter (23) where the crystal component is recovered as a cake layer on a filter cloth surface thereof, washing the cake with 95% acetic acid to thereby remove mainly impurities from the crystal component and feeding the obtained crystal component into re-slurrying tank (24); feeding pure water alone into the re-slurrying tank (24) to thereby obtain a re-slurry from the cake; and feeding the re-slurry into second rotary filter (30) where the crystal component is recovered as a cake layer on a filter cloth surface thereof and washing the cake layer with pure water to thereby remove acetic acid.

摘要： The present invention relates to a method for treating a pulp suspension in which the suspension is rotated in a rotationally symmetrical, rapidly rotating and permeable screen basket so that the suspension is subjected to the influence of a centrifugal force and dewatered at the same time as the suspension is conveyed by a rotating screw along the inner wall of the screen basket. The invention is characterized in that the suspension is caused to rotate by means which are arranged at the entrance to the screen basket, and in that the outer edges of the said screw bear against or are immediately adjacent to the screen basket and rotate at a higher speed than does the screen basket so that the screw scrapes the inner wall of the screen basket. The invention also relates to a device for implementing the method, which device comprises a housing (12), a screen basket (20) which is rotatably arranged in the said housing (12) and which is provided with screen openings, a screw body (72) which is rotatably arranged in the said screen basket (20) and which is arranged with a screw blade (79), an inlet (59) to the said screen basket (20) for the pulp suspension which is to be treated, an outlet (46, 52) from the said screen basket (20) for the pulp suspension which has been treated, and on outlet (62, 64) from the said housing (12) for liquid which has been removed. The device is characterized in that the said screen basket (20) is able to be rotated, via a transmission (26) which is arranged with a gearing, by a drive element (30), in that the screw body is able to be rotated, via a transmission (84) which is arranged with a gearing, by the said drive element (30), in that the screw blade (79) of the said screw body (72) moves along the inner side of the screen basket (20), with the gearing of the transmissions (26,84) being chosen so that the screw body (72) rotates faster than does the screen basket (20), so that the screw blade (79) has a scraping effect on the inner side of the screen basket (20), and in that an element (102) for initiating rotation of the pulp suspension is arranged at the inlet (59) to the screen basket (20), which element (102) is able to cause the pulp suspension to rotate when it enters the said screen basket (20).

Date Jan. 26, 1995A method and apparatus thickens lime mud with a disc filter in such a way that the precoat layer on the filter surfaces of the disc filter can be cleaned. Beneath the scrapers for scraping a dry layer of lime sludge from the precoat layers on the disc filter wires surfaces one or more high pressure nozzles, and optionally a low pressure nozzle, are provided for directing jets of liquid at the precoat layer and wire surface. One high pressure nozzle may remove the precoat layer while another cleans the wire surface, and the nozzles may be reciprocated (with respect to the shaft for rotating the disc filters in a trough). The high pressure jets provide liquid at a pressure of about 30-100 bar, while the low pressure jet pressure is between 2-30 bar and may be utilized continuously, or arrested when the high pressure jets are operable.

摘要： A process for recovering crystals from a slurry which comprises supplying a slurry comprising crystals and a solvent to a rotary vacuum filter and successively conducting filtration under suction, washing, filtration under suction and cleavage of a cake continuously by rotation of a cylindrical filter medium, wherein a vapor having a same composition as that of the solvent is supplied as a blowing gas for cleaving the cake. The crystals can be continuously recovered for a long period of time without clogging of a filter medium when the crystals are recovered from a slurry by using a rotary vacuum filter.

摘要： An apparatus and method for filtering and classifying waste or process streams into three product streams using a polymeric net belt to drive a filter drum and hydrophobic polymeric filter element thereon. A matte of solids is doctored from the belt to provide a first product stream. A roller mounted on a fluid cylinder driven pivoted arm compresses the filter element to provide a smaller suspended solids stream for collection in a trough inside the drum. This second product stream is removed axially from the trough by means of a pump. A third clarified or effluent stream is produced and collected in the drum as the stream passes through the foam filter element. This third stream is removed axially in the direction opposite of said second stream. A shower keeps the foam in the compressed area water filled to prevent vapor lock or gas blockage in the cellular foam filter.

摘要： PCT No. PCT/FI94/00134 Sec. 371 Date Nov. 16, 1995 Sec. 102(e) Date Nov. 16, 1995 PCT Filed Apr. 7, 1994 PCT Pub. No. WO94/23821 PCT Pub. Date Oct. 27, 1994A method and apparatus to clean a filter drum used for thickening lime mud. The drum is rotated about a horizontal axis in a first direction so that the circumferential surface of the drum moves into contact with lime mud in a vat and a precoat layer formed on the drum, as well as an external layer of lime mud which forms a thickened lime mud cake when a vacuum is applied to the drum withdrawing liquid from the lime mud. The thickened external layer of lime mud cake is scraped from the drum at a second side of the vat, and at a first opposite side of the vat a first jet of liquid is directed onto the drum surface (e.g. at a pressure of about 30-100 bar) to remove a strip of the precoat layer, a third jet of liquid cleans the drum after removal of the precoat layer, and a second jet of liquid is directed onto the drum with sufficient intensity (e.g. a pressure of about 2-20 bar) to remove, by spreading and partially detaching, a strip from the thickened lime mud cake. Typically the second jet is operated substantially continuously, except when the first and third jets are operated, the first and third jets being operated at spaced time intervals (e.g. periodically or intermittently). The invention results in partial removal of the precoat with a gentle liquid jet, easy removal of the entire precoat layer because the precoat is not yet hardened at its location of movement, intermittent use of high pressure jets which extends the life of the high pressure apparatus in the wire forming the drum, and optimum ease of installation and maintenance of the spray nozzles.
