A connecting element (1) for connecting at least two end portions (2A, 3A) of a flat filter medium (2, 3) has at least three legs (1A, 1B, 1C), one end portion (2A, 2B) each being introducible between two legs (1A, 1B, 1C). Under the influence of heat it is possible to connect the material of the legs with the material of the filter medium (2). The connecting element (1) can be used in a filter element (4) and in particular in a filtering device (5), for example an operating fluid filter for a motor vehicle. The object of a method for connecting at least two end portions (2A, 3A) of a flat filter medium (2, 3) is that the end portions (2A, 3A) are introduced between two legs (1A, 1B, 1C) each of a corresponding connecting element (1) and that through heating the material of the legs is connected with the material of the filter medium (1).

Corrugated fluid treatment packs and methods of making corrugated fluid treatment packs are disclosed. The fluid treatment packs may comprise a non-woven fibrous structure and/or porous membrane having a tubular configuration and a longitudinal axis, the fibrous structure and/or porous membrane being corrugated to define at least one crest, at least one trough, and at least one corrugation, each corrugation including first and second webs, the first and second webs extending into one another along a crest or a trough. The crests, troughs, and corrugations may include webs may which extend circumferentially or helically.

The present disclosure is directed to systems and methods of manufacturing filter cartridges are disclosed, the system including a tube of laminated and seamed filter media, a media unwind mechanism, a mandrel having a starting point operatively positioned proximate the media unwind mechanism, structure, operatively positioned proximate the mandrel, for feeding the tube of laminated and seamed filter media into the starting point of the mandrel, structure, operatively positioned in the mandrel, for pressurizing the tube of laminated and seamed filter media with a gas, structure, operatively positioned in the mandrel, for expanding the tube of laminated and seamed filter media into a substantially cylindrical shape as the tube of laminated and seamed filter media passes over the mandrel, a pleater mechanism, operatively positioned proximate the mandrel, a blade mechanism, operatively associated with the pleater mechanism, for alternately engaging the tube of laminated and seamed filter media with the blade mechanism, structure, operatively positioned proximate the pleater mechanism, for moving newly formed pleated filter media downstream; and structure for compressing the tube of laminated and seamed filter media radially toward the mandrel. Methods of manufacturing filter cartridges are also disclosed.
摘要:
The filter assembly includes a filter unit disposed in a vertical tank and includes a first end plate or drain head having an opening in fluid communication with a filtrate port in the tank, a longitudinally movable second end plate or compression head spaced in generally parallel relationship to the drain head and an elongated sleeve of flexible filter material, such as a woven fabric, connected to and extending between the drain and compression heads to define a filtrate chamber. When the filter tube is in an expanded or extended condition (filtering position), a portion of the fluid, such as a wash water from a vehicle washing facility, entering the tank passes through the filter tube into the filter chamber and the thus-filtered water exits therefrom through the filtrate port. Excess wash water in the tank overflows through an overflow outlet. When it is desired to remove materials collected on the outer surface of the filter, the compression head is moved toward the drain head to compress the filter tube (purge position), a portion of the filtered water in the filter chamber is forced back through the filter tube for back flushing and at least a substantial portion of the material dislodged from the filter tube is carried from the tank with the overflowing waste water. The compression head is periodically cycled between the filtering and purge positions at predetermined time intervals by a timer-controlled, fluid-actuated cylinder.
摘要:
The invention relates to a filter system comprising a housing and a filter element being accommodated in the housing, wherein a safety assembly is arranged inside the housing, having a blocking mode and an unblocking mode depending on an axial and/or rotational position of the filter element in the housing and being configured to provide access of a sealing structure of the filter element to a sealing area of a housing cover in the unblocking mode and to block access of the sealing structure to the sealing area in the blocking mode when the sealing structure of the filter element is moved towards the sealing area. The invention further relates to a safety assembly for a filter system and a filter element.
