Process for producing finished mouldings with regions of different cross-section, in particular chamber and membrane filter plates for solid-liquid separation

The invention relates to a process for producing finished mouldings with regions of different cross-section from thermoplastic materials, in particular chamber and membrane filter plates for solid-liquid separation, in a heatable compression mould comprising an upper part and a lower part. The invention is characterised in that first of all a plate-shaped preform, adapted approximately to the relative cross-section and volume dimensions of the finished moulding is laid in the compression mould. Then, during closing of the compression mould, the regions of the preform initially bearing against the compression mould are superficially melted. The material thus melted is displaced by the final closing of the compression mould into the still existing cavities of the compression mould.

Filters and Filter Units

A filter unit comprises a plastics frame (10) into which a sheet of filter medium (19) is insert moulded. Portions of the frame form apertures (14) and other portions allow fluid access to and from the opposed surfaces of the filter medium (19) when the frame is covered by a flat surface. The frames also form portions of an integral capsule enclosing the medium. A number of such filter units (24) can be stacked together in various configurations so that the apertures (14) form inlets and outlets for fluid so that, in some configurations, fluid can be passed through the filter units in parallel while, in other configurations, fluid can be passed through filter units in succession. Filters of any convenient size can be produced by increasing the number of filter units (24) in a stack. The filters are bi-directional. The frames (10) can be of polypropylene connected to hydrophilic microporous nylon membrane by injection moulding, which has been found to give a filter unit that can be integrity ...

A method and apparatus are provided, for forming a filter element including a media pack in the form of a coiled web of fluted filter media, by feeding the web of fluted filter media at a controlled linear speed onto a mandrel rotated by a winding motor providing a controlled driving torque to the mandrel, to thereby maintain a controlled tension on the web of fluted filter media as the web is would onto the mandrel. The web may be fed at a substantially constant linear speed to the mandrel, and/or the winding motor may be controlled in a manner providing substantially constant driving torque to the mandrel for maintaining a constant tension on the web as a function of the constant driving torque. Coiled media packs having circular or non-circular cross sections, can be formed with either cored, or core-less construction.

Filter core and manufacturing method thereof

A filter core and manufacturing method thereof, the manufacturing method has the following steps: adhering a wavy filtering sheet and a flat filtering sheet, pressing the filtering sheets, and rolling the filtering sheets. A part of peaks of the wavy filtering sheet are pressed to lean toward a same side. In particular, two sides of a first end sealing adhesive layer are pressed. Thus, the first end sealing adhesive layer is concentrated, such that the glue is uniformly spread to the two sides. Besides, the pressing on the two sides makes the two sides of the first end sealing adhesive layer adhered securely, thereby preventing the wavy filtering sheet from rebounding upward and forming bubbles. Thus, the first end sealing adhesive layer can be formed with less quantity of glue, which accelerating the cooling and raises manufacture efficiency.

MULTI-STAGE SPIRAL-WOUND FILTER

A multi-stage filter formed by spirally winding a multi-layer material around a core to form a generally cylindrical construction having two opposing spiral end surfaces. The multi-layer material is formed by at least one filter layer, and at least two spacer layers formed from a material with a high void volume. The layers are arranged so that during use, and in each stage, unfiltered fluid in each layer passing through one spiral surface into one spacer layer must pass through a filter layer prior to passing out of the construction through the opposing spiral end surface. Fluid in each stage passes through the filter in an opposite axial direction than the fluid passing through the filter in adjacent stages.

The winding frame is a substantially open, truss-like structure, having a smooth outer periphery and an axially extending winding feature to facilitate pulling the media into intimate contact with the smooth outer periphery during fabrication of the filter element. A leading edge of the filter media is anchored to a leading edge of the frame by a length of tape.

Способ изготовления фильтрующих элементов

Filter pads, which are made inherently stable by binders and by removal of the binders can be converted in packings to be maintained under substantially constant surface pressure between rigid filter brackets, are produced first as molded bodies from a suspension of filter aids in liquid by depositing granular, fibrous, or fiber-containing filter aids or mixtures of those filter aids in a casting mold, there being used high rates of flow while avoiding turbulences, and adding binders to the suspension so that the molded body can be stabilized by activation of the binder while drying. It is possible in this process also to manufacture multi-layered filter pads, it having been surprisingly found in those multi-layered filter pads that the layer assembly is kept intact during the filtration even in the filter packing that no longer contains binders. The filter pads or the filter packings produced therefrom according to the invention can, when used, and after reflushing and regeneration operations, finally be utilized, after being replaced, as filter aids in the deposit filtration process.

Manufacturing method of filtration element

Continuous production of nonwoven webs from thermoplastic fibers and products

A process is provided for the continuous production of nonwoven webs in cylindrical or sheet form from thermoplastic fibers, spinning the fibers continuously from a melt onto a rotating mandrel and winding them up on the mandrel to form a generally spirally wound cylinder. Density of the wound cylinder is controlled by controlling the distance between the rotating mandrel and the orifices of the spinning die through which the molten polymeric material is spun. If the spinning of the fibers is continuous, the cylinder can be formed in a continuous length. Control of the spinning rate in relation to the diameter and rate of rotation of the mandrel and the rate of advance of the cylinder on the mandrel controls the thickness of the cylinder. The cylinder can be drawn off the mandrel and used as a cylinder, or either slit lengthwise and opened out, or collapsed onto itself, for use as a sheet. The process is particularly adapted for forming filter elements.
