Definitions
- the invention relates to a sieve element, in particular for filtering liquid or gaseous substances, according to the preamble of independent claim 1.
- a sieve element is known from DE 195 37 269 and is arranged in an intake pipe in an internal combustion engine.
- the element is made of metal wire and has the task of equalizing the flow of the intake air and thus reducing noise.
- Such sieve elements are usually manufactured in such a way that a prefabricated sieve part is placed in an injection molding machine and overmolded there with a retaining ring. Since a certain stability of the sieve element is required, metal is preferably used for the sieve area.
- Sieve elements of the type mentioned are used in all areas of technology. Due to the requirement for a certain dimensional stability, materials with a high degree of stiffness are required.
- the invention has for its object to avoid the disadvantages mentioned and to create a screen element which has a low flow resistance, but at the same time is dimensionally stable.
- the main advantage of the invention is that a knitted fabric can be used as the material for the screen element, which is not dimensionally stable, but has a low flow resistance.
- the dimensional stability is thereby achieved that the knitted fabric is connected to a supporting skeleton.
- This supporting skeleton can consist of a thermoplastic and can be designed depending on the application, that is to say can be optimally adapted to the application. It is also possible to use thermosets or elastomers to manufacture the support skeleton.
- the support skeleton is connected to the retaining ring or the retaining element. This increases the dimensional stability.
- the knitted fabric is a plastic knitted fabric and made from monofilament or multifilament fibers.
- free-form surfaces or regular surfaces can be selected.
- Such a sieve element is suitable for various media such as air, water, fuel, oil or the like and can be used both in automobile construction and in medicine or in general plant construction.
- One advantage of using a knitted fabric is its high elasticity, both in the longitudinal and in the transverse direction. This elasticity prevents damage to the screen element when subjected to heavy loads.
- a method for producing a sieve element for filtering liquids or gases with a holding ring and holding element, a sieve filter arranged thereon has the following steps: A knitted fabric is inserted as a sieve filter in a production machine and can be made with a supporting skeleton and a holding ring and holding element made of thermoplastic material encapsulated. In a preferred embodiment of the invention, the knitted fabric can be fed from a belt to the machine.
- Figure 1 shows a screen basket in side view
- Figure 2 shows a screen basket in a plan view
- FIG. 1 The side view of a screen element according to FIG. 1 shows a retaining ring 10 which is inserted in a tube 11. Air or liquid is supplied through this tube according to arrow 12, flows through the sieve element 13 and leaves this filter area cleaned according to arrow 14.
- the sieve element 13 consists - as already mentioned - of a retaining ring 10, a knitted fabric 15 is arranged thereon, and a supporting skeleton 16 for the knitted fabric.
- the knitted fabric is a textile fabric which is produced by knitting or knitting.
- the special characteristic of the knitted fabric or the knitted fabric is its elasticity, the yielding in tension in the longitudinal, transverse and diagonal directions and returning to the old position when the stress ceases.
- Knitwear can be shaped very well, the degree of elasticity depends on the material, the stitch strength and the type of binding.
- Another valuable property is the high air permeability. In particular when used as a sieve or filter element, this high air or liquid permeability is required with a good ability to retain foreign substances.
- the support skeleton 16 is connected to the retaining ring 10 and is produced in a thermoplastic injection molding process and connected to the knitted fabric 15.
- An advantage of this support skeleton is that very particularly heavily stressed areas or surface areas of the screen element 13 can be equipped with a reinforcing structure.
- Figure 2 which includes the top view of the screen element 13, the support skeleton 16 is essentially adapted to the contour of the retaining ring 10, the heavily loaded middle area of the knitted fabric 15 is equipped with a continuous longitudinal web 17.
- This longitudinal web 17 has the task of intercepting the main pressure of the fluid to be cleaned.
- the curved design of the sieve element 13 on the one hand increases the effective filter area, on the other hand the section modulus towards the fluid and against the flow direction is increased.
