摘要:
Die Erfindung betrifft eine Filterkerze für Anschwemmfilter zur Filtrierung von Fluiden, insbesondere von Bier mit einem rohrförmigen Filterkörper (2) mit Fluiddurchlässen (11). Damit die Verschnittmenge von verschiedenen Medien für verschiedene Prozessschritte reduziert wird und sich gleichzeitig eine verbesserte Stabilität der Filterkerze ergibt, ist im Innenraum des Filterkörpers (2) ein Innenkörper (3) mit geschlossenem Außenmantel angeordnet.

Die Erfindung betrifft ein Verfahren zur Filtrierung und/oder Stabilisierung von Fluiden, insbesondere von Bier und eine Filterkerze zur Durchführung des Verfahrens mit einem rohrförmigen Filterkörper, der aus einem spiralförmig gewundenen Draht gebildet ist, wobei Spalte zwischen den Drahtwindungen als Fluiddurchlässe vorgesehen sind. Um eine Filterkerze bereitzustellen, die ermöglicht, Filterhilfsmittel und somit Filterkosten zu sparen, weist die Außenfläche einer Drahtwindung, die auf der Außenseite der Filterkerze liegt, eine Breite
摘要:
The invention relates to an extremely low-noise, low-vibration elutriation filter which is used to filter e.g. coolant lubricant. In said filter, a filter candle (12) which encompasses an ascending channel (16) is mounted into a separation plate (5) using an uptake tube (15), in such a way that it can be displaced axially. The filter cake which adheres to the exterior of the filter candle (12) is dislodged by means of a rotational body (40) e.g. in disc form, which has a shoulder (42) running along its glide path (41) between the end of said glide path (43) and the start (44) of the same. As soon as a head end-section (20) that is connected to the uptake tube (15) and that can be displaced axially against the force of a spring (21) by the glide path (41) is released from the rotating end of said glide path (43), the accumulated force of the spring (21) accelerates the filter cake (12), in such a way that the filter cake adhering to the filter candle is dislodged, both by the acceleration of the latter (12) and the impact caused when a damping ring, situated between the filter candle (12) and the separation plate (5), strikes said separation plate.

A multiple tube filter device is disclosed for filtering beer. In order to ensure a uniform inflow of non-filtrate and filter auxiliary substances into such a device, a rising pipe for distributing the medium to be filtered inside the body of the device has at least one dispensing aperture, and a deflector causes the direction of flow of the medium to be filtered to change several times.
摘要:
Known filters which operate according to the deep bed filtration principle present the disadvantage of having a filter resistance which increases together with the utilization duration. By using a filter operating according to the superficial filtration principle, a constant efficiency is insured since foreign particles are deposited on a weather-proof, non hygroscopic sliding surface (5) and that they do not penetrate inside the filter element (3). The latter may be cleaned in a simple way if it was soiled during the back blowing operation.
摘要:
A filter element, a system and a method are disclosed for purifying a mixture comprising aqueous liquid, particulate matter and a water-immiscible organic liquid. The filter element (10) comprises at least one sheet of a microporous, non-woven aramid fiber medium having opposing edges secured to each other and defining a cylinder, two endcaps sealed to opposite ends of said cylinder in fluid-tight relationship, at least one of said endcaps having an aperture formed therein, and wherein all of the materials from which said filter element is formed are polymeric materials. Such an element (10) may be comprised in said system (60) which also comprises a housing (70), at least one fluid inlet (71) in said housing, at least one fluid outlet (77) in said housing, and means (73,74) to backflush liquid through the system. In use the element or the system is used to treat said mixture, the medium retaining at least the particulate matter.

PCT No. PCT/FI88/00193 Sec. 371 Date Jul. 19, 1989 Sec. 102(e) Date Jul. 19, 1989 PCT Filed Dec. 1, 1988 PCT Pub. No. WO89/05184 PCT Pub. Date Jun. 15, 1989.A procedure and means for filtering and homogenizing liquid substances and for automatic cleaning of the filters. In the procedure are utilized an ultrasonic generator (4) connected in conjunction with the filter unit (1; 2) and ultrasonic oscillators (1.11; 2.11) thereto connected, their power and frequency being controlled on the basis of the differential pressure present across the filter units (1; 2), the liquid pressure acting in the filter unit, the liquid flow rate, signals from liquid temperature pick-ups. In order to enhance the cleaning event of the filter elements (1.2; 2.2) taking place with ultrasonics, the filter unit (1; 2) is emptied during the cleaning phase, making use of compressed air conducted into the filter. In order to facilitate the liquid filtering event and to reduce the need of cleaning action with ultrasonics, during normal filtering an ultrasonic power is maintained which is sufficient for homogenizing the liquid. The filter unit (1; 2) furthermore contains one or several cylindrical filter elements (1.2; 2,2).
摘要:
A filter apparatus comprises a plurality of ceramic porous filter elements (l) each having parallel passages separated by filtering walls, with the passages closed at either the inlet side (4) or the outlet side (6) to form inlet and outlet passages respectively. The elements are in individual casings (l5) piled one above the other with the filter elements (l) being spaced apart from each other. Raw liquid to be filtered is supplied to the inlet sides (4) of the filter elements via supply chambers (36) located between the filter elements. Filtrate discharge chambers (37) are located between the filter elements for receiving filtrate which has passed through the filter elements. With this arrangement, raw liquid passages and filtrate passages are completely separated, so that no mixture of the raw liquid and the filtrate occurs, and therefore filtering can be effected with high efficiency and high reliability. The apparatus can be light in weight.
