Description

Field of the invention

The present invention relates to a self-contained disposable filtration unit, comprising a plurality of plate elements and filter cassettes disposed therebetween, with a handling device for safe transport and easier handling.

State of the art

Filtration units are used for example in the ultrafiltration and microfiltration of liquids. They are traditionally made of filter cassettes, which are clamped and pressed together with the aid of a filter holder between plate elements. The plate elements are designed as end plates, distributor plates, collecting plates and / or separating plates and have connections for feed liquid and filtrate as well as connections for concentrate in crossflow filtration. Such filtration units are for example from DE 34 41 249 C2 . DE 44 32 627 A1 or the DE 100 00 186 C2 known. Disadvantage of such an arrangement is that after use of the filtration unit disassembly and cleaning is complex and unwanted contamination is possible. Therefore, the use of self-contained single-use filtration units (disposable filtration units) is becoming more prevalent.

Out DE 10 2007 025 541 B3 is a self-contained disposable filtration unit known. This consists of plate elements and arranged between filter cartridges, wherein the filter cartridges are positively and fluid-tightly connected with their adjacent plate elements in a peripheral portion of their contact surfaces by an adhesive. The arrangement can be expanded as desired by juxtaposing further filter cassettes and plate elements. Such a juxtaposition makes sense in order to effectively filter large quantities of liquid in an installation and to make industrial production processes economical. A juxtaposition of other filter cartridges and plate elements is out DE 20 2014 105 959 U1 known.

The disadvantage, however, is that when transporting the self-contained disposable filtration units due to material stresses they can be damaged and their handling is difficult with increasing size due to the heavy weight.

task

The invention is therefore based on the object to improve a self-contained disposable filtration unit so that the risk of damage during transport significantly reduced and their handling is facilitated.

Presentation of the invention

The object is achieved by a self-contained disposable filtration unit, which consists of at least two plate elements. The plate elements may be formed as end plates, distributor plates, collection plates and / or separator plates. Filter cassettes are arranged between the plate elements. Concrete embodiments of filter cassettes or plate elements are known in the art. The self-contained disposable filtration unit is provided with at least one handling device. Handling devices facilitate the transport of the self-contained disposable filtration unit. A handling device can be attached to fastening and / or support elements, which are formed on the plate elements.

Self-contained, single-use filtration units are to be understood as those filtration units in which, on the one hand, the plate elements and filter cassettes are connected in a fluid-tight manner and therefore generally do not require a separate filter holder for operation and, on the other hand, consist of polymeric materials, which facilitates their disposal.

Support members formed on a plate member stabilize the self-contained disposable filtration unit and prevent damage.

According to a preferred embodiment, the fastening and / or support elements of adjacent plate elements are interconnected. Particularly preferably, a connection is made by bridging elements, which connect the plate elements parallel or transverse to the base of the self-contained single-use filtration unit. The bridging elements can be rigid or elastic. The bridging elements can have different shapes, preferably the bridging elements are rectangular.

According to a further embodiment, at least one support element has at its lower end at least one leg which runs parallel to the base of the filtration unit. A leg may be connected to one or more plate elements. The leg is preferably connected to all plate elements and extends over the entire self-contained disposable filtration unit.

According to a further preferred embodiment, the support element encloses in a cage-like manner the self-contained disposable filtration unit. Particularly preferably, the support member has through holes or holes to allow the attachment of media-carrying hoses. The support elements or plate elements may have suspensions to fix hoses for transport.

Preferably, at least one support element is constructed partially or completely from an elastic material. Particularly preferably, a plurality of elastic support elements are formed on a plurality of plate elements, so that they are arranged symmetrically on the self-contained single-use filtration unit. Elastic support elements can dampen their impact, for example, when the self-contained disposable filtration unit falls down. Elastic support elements are preferably made of nonwovens or elastomers, for example rubber.

The handling devices can be attached to the support elements and / or the fastening elements. Serve preferably fasteners. A handling device has at least one first attachment means.

A second attachment means is formed on the attachment and / or support member. Both fastening means correspond to one another and serve for the firm connection of fastening or supporting element and handling device.

Preferably, the handling devices are designed as loops, wheels, hooks, brackets and / or handles.

Preferably, the handling device is designed as a handle that allows safe manual transport of the self-contained disposable filtration unit.

According to a preferred embodiment, the handling devices are designed as loops or hooks. This makes it possible to mount the self-contained disposable filtration unit in a transport apparatus, for example in a crane or a car. This allows safe transport even of self-contained disposable filtration units whose weight is manually no longer manageable.

According to a further preferred embodiment, the handling device is designed as a wheel, preferably at least two, more preferably at least three wheels are attached to fastening and / or support elements. This makes it easy to handle the self-contained disposable filtration unit with respect to the transport in one plane. In addition, parking brakes are particularly preferred.

The handling devices can be attached to the support and / or attachment elements in various ways. They can be firmly connected, for example by gluing or welding. Preferably, the handling devices are releasably attachable to the attachment and / or support elements. They are attached to transport the self-contained, single-use filtration unit and removed prior to commissioning. As a result, in the operating state, the space can be used more efficiently and serve to accommodate, for example, connections, hoses, cables, other filtration units or other devices necessary for the process.

According to a further preferred embodiment, the handling devices are movable in at least one spatial direction relative to the self-contained, single-use filtration unit. Particularly preferably, the handling devices for self-contained disposable filtration unit can be folded. This embodiment enables efficient use of the room in the operating state.

Preferably, the filter cartridges are fluid-tightly connected to their adjacent plate element in their peripheral edge region by an adhesive.

The self-contained disposable filtration unit can be pre-assembled with attached hoses for feed liquid, filtrate and concentrate, including with sterile connector transfer sets.
