- the forces acting on the Gutteilchen centrifugal forces act and support a separation of adhering to the Gutteilchen liquids and dirt particles, which are deposited on the outer Siebmantel from the flow channel and discharged through a space provided between the outer screen shell and the container shell collecting space from the container.
- the residual moisture of the Gutteilchen evaporated in the heated air flow and is discharged with the impurities on the screen jacket from the device.
- the centrifugal force passing of the Gutteilchen on the outer screen shell and the mutual rubbing of Gutteilchen support the detachment of adhering to a Gutteilchen solid and liquid contaminants, which leads to a good drying and cleaning effect in conjunction with a corresponding high air turnover.
- the dried and cleaned material to be treated which is conveyed upwards with the air flow within the flow channel in a helical circulation movement, can be discharged via a good outlet provided in the upper area of the outer screen shell.
- the material to be cleaned is thus circulated and cleaned in the toroidal flow channel.
- such a blower also causes an immediate backflow from the radial blower outlet to the radial blower inlet, with the result that the particles of good can be trapped in this air flow, which in turn can result in a considerable impairment of the drying and cleaning effect.
- Due to their dimension by gravity due to the bottom of the container settling and held by the fan in the container bottom side excretions usually can only be removed during service life of the device via a maintenance opening from the same. Presentation of the invention
- the invention is therefore based on the object, an apparatus for drying and cleaning of Malawi Glaigem Good, in particular of shredded plastic waste, of the type described in such a way that an improved drying and cleaning effect is achieved.
- the fan comprises a rotor having three blower units in the axial direction, of which the first form the suction fan, the second the radial fan and the third one from the radial fan pointing away in the direction of blades blades unilaterally open impeller.
- the radial fan has in the usual way conveying blades, which are closed at the end by means of cover plates.
- the blades of the third impeller open on one side and pointing away from the radial fan in the axial direction can preferably be provided directly on the intake-side cover disk or fastened thereto.
- contaminated cleaning and drying air is not only discharged from the container via the collection space for the deposits, but also aspirated or discharged from the container head area, whereby a high discharge rate for the deposits is ensured.
- a filter device it is usually recommended for a device according to the invention a cyclone separator or the like.
- a sensor measuring the degree of contamination of the cleaning and drying air can be provided in the region of the filter device.
- the cycle time for the cleaning of plastic waste can thus be determined in a simple and advantageous manner as a function of the respective degree of contamination of the waste. be prepared by the device in connection with the prevailing in the container temperature and the respective residence time.
- the flow channel for the material to be treated in the container shell can be formed in a known manner between an outer and an inner screen shell, between which the material rotates in an annular manner. Improved cleaning conditions, however, arise when it is dispensed with the inner screen jacket and the material is passed directly through the air blower with the air flow in the circuit. Due to the centrifugal forces that occur, a particularly good cleaning effect of the subsequently projecting on the container shell Gutteilchen is effected.
- the radial fan be good for the material to be circulated in the flow channel except for one in the transitional area between the fan blade surface and suction-side cover provided and the cover plate breaking through gap closed radial impeller is formed.
- On the cover disc settling to be cleaned Good is always displaced by the circulating and centrifugal forces in the direction of the nearest blade surface to the gap and can be promoted because of the gap in the cover in the vicinity of the blade surface centrifugal force by the radial fan.
- FIG. 1 and 2 each a plant schematic of a device according to the invention in a partially sectioned view
- Fig. 3 shows an inventive impeller in section IH-III of Fig. 2 on a larger scale.
- a device for drying and cleaning of gar Swissigem Good comprises a stationary container 1, which forms an annular flow channel 4 for the material to be treated within a arranged on the container shell 2 screen shell 3.
- the container 1 has at least one Gutauslass 5 connected to the container casing 2 for the treated material and between the filter casing 3 and the container casing 2 at least one collecting space 6 for deposits from the flow channel 4.
- the device includes a blower 9 for a circulating within the flow channel 4 cleaning and drying air flow to the material to be treated, which blower 9 a container bottom suction fan 10 to be introduced into the container 1 plastic waste and a subsequent radial fan 11 for the flow channel includes good to be circulated.
- the annular flow channel 4 for the material to be cleaned is formed between the outer screen shell 3 and an inner screen casing 12, which prevents a flow of the Gutteilchen to be cleaned by the radial fan 11 therethrough.
- the fan 9 comprises a three axes in the axial direction 15 having fan units, of which the first the suction fan 10, the second the radial fan 11 and the third one pointing away from the radial fan 11 in the axial direction 15 Shovels exhibiting unilaterally open impeller 17 form.
- a cleaning and drying air into the container 1 einlichdes and provided with its mouth opening against the suction region 14 of the radial fan 11 projecting supply pipe 18 through which the radial fan 11 sucks fresh cleaning and drying air to the extent in which equally consumed Cleaning and drying air is discharged from the device. Furthermore belong to the container 1 not only in the area of the collecting chamber 6, but also container head side outlets 7, 19 for cleaning and drying air, both of which open together into the filter device 8.
- FIG. 3 shows a possible embodiment variant of the rotor of a blower, wherein the radial blower 11 for the material to be circulated in the flow channel as far as a gap 20, which results in the transition region between the vane-side blade surfaces 21 and the front-side cover 22 and the cover 22th breaks through, closed radial impeller is formed.
- the use of such radial impeller according to the invention is not limited only to the device shown, but is suitable for any device for drying and cleaning of Malawi Glaigem Good, with the good in an air stream to be cleaned and dried.
- the gap 20 widens in the illustrated embodiment in the conveying direction, ie from the intake 14 to the outlet 13 of the radial fan 11 out.
- the reservoir 23 which is closed by means of a slide 24 closable conduit 25 with a suction duct 26 of the Container 1 is connected.
- the slider 24 is opened with a rotating fan rotor until a corresponding amount of plastic material has been introduced via the suction duct 26, in which the product flow due to the prevailing air flows and the tangential junction of the conduit 25 is circulated, before it is detected by the suction fan 10 and registered in the container 1.
- An agitator 27 in the reservoir 23 prevents bridging and blockage. Is a corresponding amount of material to be cleaned sucked and the slider 24 is closed again, there is no flow through the suction fan 10 more.
- the radial fan 11 now ensures a corresponding circulation of the drying and cleaning air in the flow channel 4.
- the inner screen 12 is mounted at the upper portion of the rotor around the inlet opening 14 of the radial fan 11 and rotates with this, with it upwards over a Sealing edge with the container head.
- a partial flow of the air which is supplied to the device via the inlet pipe 18, heated.
- the adhering to the Gutteilchen dirt particles are knocked off the Gutteilchen on the container wall and discharged through the screen jacket 3 and the container head from the device.
- the extracted air is passed through the filter device 8 and then - recycled accordingly in terms of temperature and moisture content - re-introduced into the device.
- the intake duct 26 is provided with a discharge 28, which may be formed, for example in the form of a rotary valve and provides for a Gutaustrag if there is no filling requirement ,
- a temperature sensor is provided in the container 1, which monitors the container temperature. When introducing moist and contaminated material, the temperature inside the container drops. If the temperature is rising again, the Drying initiated and completed from a specified temperature. In addition, the discharged from the device amount of dirt particles is measured with a corresponding meter and discharged in the presence of a desired degree of purification, the material through the lock 5 from the drying room.
