摘要： Die Erfindung betrifft ein Eckrohrsieb (1) für aseptische Produktbehandlung und ein Verfahren zur automatischen Abreinigung desselben. Mit der Erfindung wird eine sichere und zuverlässige Reinigung und/oder Sterilisierung des Eckrohrsiebes im Durchfluss unter aseptischen Bedingungen erreicht, ohne dass der mit Siebrückständen beladene Siebeinsatz aus dem Eckrohrsieb ausgebaut werden muss. Dies wird gegenständlich unter anderem erreicht durch die Durchtrittsöffnung (5e), die von einem den Siebmantel (5a) stirnseitig berandenden Sitzring (5d) umschlossen ist, wobei in oder an der Durchtrittsöffnung (5e) eine erste Sitzfläche (5f) ausgebildet ist, wobei die Durchtrittsöffnung (5e) über ein translatorisch verschiebliches Schließglied (4a), das mit einer zweiten Sitzfläche (4c) mit der ersten Sitzfläche (5f) zusammenwirkt, wahlweise geöffnet oder geschlossen wird, wobei das Schließglied (4a) über eine durch den Gehäusedeckel (6) hindurchgeführte Ventilstange (4e) mit einem fernsteuerbaren Antrieb (3) verbunden ist, und wobei diese Durchführung mit einem Balg (4b) überbrückt ist, der die Ventilstange (4e) koaxial umschließt und der einerseits mit dem Schließglied (4a) und andererseits mit dem Gehäusedeckel (6) verbunden ist (Figur 2).

摘要： Equipment and procedure for the separation of solid particles and colloids suspended in liquid with automatic washing system of filtering meshes by means of high pressure water jets generated by a group of mobile spray nozzles, moved vertically by a hydraulic piston controlled by the same washing liquid pressure, operating when the filter is empty of liquid in filtration. The liquid jets are generated by a single nozzles or a group of nozzles, supplied with water through the shaft of the same piston. The nozzles are disposed in such a way to sprinkle the whole surface of the filtering mesh. Feeding the cylinder upper chamber with washing liquid with suitable pressure and flow determines the descending movement of the piston and with it of the nozzle or group of nozzles, mounted at the end of the piston shaft. The velocity of movement of the group of nozzles is regulated, creating in different ways, a resistance to the flow of liquid from the cylinder lower chamber. The upward motion of the plunger to its starting position is obtained by the injection of the liquid, which comes from a pneumatic device or from a dedicated circuit, in the cylinder lower chamber, with the consequent flow of liquid from the superior chamber through the nozzles.

摘要： The present invention relates to a system and a process of running the system that allows for the long term filtration of product without loss of filtration capability due to clogging or fouling. The system is a normal flow filtration system having one or more filter cartridges attached to an outlet of a housing in the system. The filter cartridge(s) are contained within a bowl and depend preferably vertically from the outlet. Liquid enters the bowl of the housing and contacts the outer surfaces of the one or more cartridges. Impurities are trapped on or in the surface of the filter and the filtered liquid flows through the filter and through the outlet. One or more parameters such as flow rate, transmembrane pressure drop and/or time are measured and when the desired parameter(s) are met, the filtration ceases. A backflushing occurs back through the filter cartridges so as to remove the trapped impurities on or in the filter surface. This backwashed material is directed to an outlet of the bowl that is connected to a drain. Additionally a port formed in the side of the housing adjacent an outer surface of the cartridge(s) can be used to provide a lateral washing of the filter surfaces. The system is then recirculated in a downstream manner to reestablish equilibrium and filtration is the restarted.

摘要： The invention relates to a device and a method for the purification of effluent. The device comprises a filter container (1A), containing a filter medium (2a, 2b), through which the contaminated effluent (3) is run in a direction (filtration direction), thus depositing dirt particles on the filter medium (2a, 2b). The risk of filter blocking is present in such filtration devices, especially at low filtration speeds. It is known that filter blockages can be avoided by the addition of flocculating agents or by increasing the filtration speed. The addition of flocculating agents makes the filter process more expensive and increasing the filtration speed reduces the quality of the filtrate. According to the invention, a high filtrate quality may be guaranteed without addition of flocculating agents with said device, whereby the cross-sectional area of the filter container (filtration area) running perpendicular to the filtration direction, expands in the filtering direction, whereupon the speed of the effluent being run through (filtration speed) continually reduces along the filtration direction.

摘要翻译： 本发明涉及用于净化流出物的装置和方法。 该装置包括含有过滤介质（2a，2b）的过滤容器（1A），受污染的流出物（3）通过该过滤介质沿过滤方向（过滤方向）流动，从而将灰尘颗粒沉积在过滤介质（2a，2b ）。 过滤器堵塞的风险存在于这种过滤装置中，特别是在低过滤速度下。 已知通过添加絮凝剂或通过提高过滤速度可以避免过滤堵塞。 絮凝剂的加入使得过滤工艺更加昂贵，并且增加过滤速度降低了滤液的质量。 根据本发明，可以在不添加絮凝剂的情况下保证较高的滤液质量，由此过滤容器（过滤区域）垂直于过滤方向延伸的横截面积在过滤方向上膨胀，于是 流出物的流速（过滤速度）沿过滤方向不断降低。
