Definitions
- the invention relates to a device for the continuous filtering of material mixtures, in particular for the separation of impurities from plastic melts, according to the preamble of claim 1.
- Used plastics or waste plastics usually have high levels of foreign matter, such as e.g. Metal parts, paper remnants, glass, secondary plastics and the like. These foreign substances or impurities must be removed before recycling the plastics in the rule. This is often done by first plasticizing the used plastics by heating and then filtering the plastic melt. For this purpose, so-called melt filters are used, by which the metallic or non-metallic foreign substances or higher-melting plastics are separated. However, to allow continuous and trouble-free filtration, the melt filters must be constantly cleaned.
- the object of the invention is to provide a device of the type mentioned, which allows improved removal of the retained on the filter element residues.
- a significant advantage of the device according to the invention is that the contact pressure of the scraper can be adjusted automatically without intervention from the outside to the actual conditions. If e.g. the pressure of the supplied material increases and thus increases the risk of lifting the scraper, according to the invention, the contact pressure of the scraper automatically increases without intervention from the outside. When the pressure of the supplied material drops, however, the contact pressure of the scraper is reduced accordingly, thereby reducing the friction between the scraper and the filter element.
- the pressure transducer is a hydraulic pressure transducer, which detects the pressure of the supplied material upstream of the filter element and converts it into a hydraulic control signal.
- the actuator consists of a connected to the hydraulic pressure transducer via a hydraulic line actuating cylinder through which the control pressure is converted into a contact pressure for the scraper.
- the pressure sensor can also be an electrical pressure transducer, which supplies appropriate control signals for a pressure control valve or an electric actuator.
- the filter residues are lifted in the radial direction of the filter surface and thus removed as quickly as possible from the filter surface.
- the residues are not pushed along the filter surface axially, so that the wear is reduced and the stability of the device can be improved can. Due to the lower abrasive stresses of the filter also simpler constructed and cheaper filters can be used.
- the lifted off by the scraper material is expediently removed by a screw conveyor or the like.
- the filter element and the screw conveyor can be driven separately, so that a separate control of cleaning and Fremdstoffaustrags Republic is made possible. By such a regulation, a very high concentration of foreign substances and thus a high yield of the primary material can be achieved.
- the conveyor device consists in an expedient embodiment of a motor-driven screw conveyor screw. The speeds of the filter and the screw conveyor can be controlled separately, whereby a very high concentration of impurities can be achieved with an optimum active filter surface.
- the filter and the screw conveyor may have the same or opposite directions of rotation.

- the filter tube 11 can also be provided with surface coatings, by which the wear resistance and other properties can be improved.
- the passage openings 10 are designed as bores with a widening in the flow direction cross-section.
- the passage openings 10 may be e.g. taper conically towards the outside.
- the hollow cylindrical support body 12 has on its outside a plurality of circumferential grooves or flat thread running as collecting channels 13, of which a plurality of circumferentially equiangularly spaced radial outflow holes 14 lead inward.
- the radial outflow holes 14 open into axial collecting slots 15 which are arranged distributed within the support shaft 4 at equal angular intervals as the outflow over the circumference of the enlarged receiving part 6 and form an interior for collecting the filtered material.
- the collecting slots 15 that expand in the direction of flow lead to a central collecting channel 16, which opens into a first annular channel 17 within the housing 1 via an oblique section.
- a first lateral bore within the housing 1 leads to an outlet channel 18 of a connecting piece 19.
- In the connecting piece 19 is also an inlet channel 20, via a second lateral bore within the housing 1 to a second annular channel 21 in the housing 1 leads.
- This annular channel 21 is in communication with an annular space 22 which is delimited between the inner wall of the housing 1 and the outer wall of the filter tube 11.

- a parallel to the central axis 3 of the filter element 2 screw conveyor 24 is disposed within the housing 1, which leads on the outside of the filter element 2 along to an outlet opening.
- the screw conveyor 24 is arranged so that the residues scraped off radially by the scraper 23 are transferred directly to the screw conveyor 24 and transported away from the latter in the direction of the arrow 25 of FIG. 1 to the outside.
- the scraper 23 is mounted on a screw conveyor 24 surrounding and rotatably mounted within the housing 1 arranged hollow shaft 26 which is rotatable via an adjusting lever 27.
- the angle of attack ⁇ and the contact pressure of the wiper 23 can be changed.
- cooling channels 29 are provided in the region of the material outlet of the screw conveyor.
- the scraper 23 may also be mounted in a predetermined angular position in the housing 1, as shown in Figure 3. There, the scraper 23 is slidably guided in an oblique slot 31 in the housing 1 and is pressed by an actuator of an adjusting device described in more detail below to the outside of the filter tube 11.
- An input-side mass pressure transducer 35 and in the region of the outlet channel 18 an outlet-side mass pressure transducer 34 are provided on the connecting piece 19 in the region of the inlet channel 20. These are connected to a control electronics 36 for controlling the filter device.
- the control electronics 36 for example, the rotational movement of the filter body 2 and the screw conveyor 24 can be controlled as a function of a detected differential pressure. This makes it possible, the filter element 2 and the screw conveyor 24 according to two predetermined pressure values (max-min) to rotate intermittently and so reduce wear.
- two predetermined pressure values max-min
- FIG. 4 shows a first exemplary embodiment of a setting device for pressing the scraper 23 in the form of a knife or a blade against the outside of the filter tube 11 as a function of the pressure of the material mixture supplied.

- the actuating cylinder can also be designed as a double-acting differential cylinder with an additional pressure port 52 for recovery.
- the pressure of the material supplied through the inlet channel 20 is transferred to the pressure piston 45, which generates a corresponding control pressure in the pressure chamber 46.
