Definitions

  • the invention relates to a method and apparatus for removing dust and / or fibrous admixtures of light small parts or a plastic granules as bulk material, in which the small parts or granules are passed to at least one perforated inclined surface in a closed elongated housing of a cleaning device, said the cleaned of adhering dust and / or fibrous admixtures small parts or granules are discharged and the holes in the inclined surface are smaller than the small parts or granules diameter.
  • From the DE 100 54 418 A1 are a method and an apparatus for removing dusty and fibrous admixtures of bulk material, which consists of particles, in particular granules, known.
  • the bulk material is passed on at least one inclined surface of an air classifier and fluidized.
  • the fluidized bulk material flow is subjected to sharp air jets transversely to a flow direction in order to achieve a separation between dusty and fibrous admixtures on the one hand and cleaned bulk material on the other hand, the air jets lead to a slowing, nearly vertical air flow in the separation area, which is adjusted so that the heavy particles of bulk material fall out of the air stream, while the lighter dusty and fibrous impurities are discharged with the air stream.
  • This method and the device are relatively complicated, elaborate and require a fluidized bulk flow.
  • DE-AS-1 213 387 From the DE-AS-1 213 387 is a device for dedusting granules, in particular of plastic granules, according to the principle of current classification known.
  • This device has a vertical separating tube, which opens with its lower end in a reservoir for receiving the granules and its upper end terminates in two concentrically arranged tubes, wherein the cross-sectional area of the outer annular space is dimensioned such that the rate of rise of the liquid in the outer annulus is approximately equal to the rate of rise in the separation tube and at the top of the circumference of the outer tube an outlet for the laden with dust separating liquid is provided.
  • it is a wet process that is extremely expensive.
  • an ionization electrode equipped with a ventilation system is provided on the inlet side of a suction box extending over the width of the web and arranged at a small distance from the web above and / or below it, connected to a suction fan.
  • Air can be used as the gas or else a protective gas, ie an inert gas, preferably nitrogen. This avoids ozone formation at the spray tips of the electrodes.
  • the DE-PS 558 456 describes a coal and mountain shearing method using a skimmer, wherein the coal is carried along with the mountains on a sloped surface having no breakthroughs, but a defined arcuate shape opening into a gap provided as a separation gap.
  • the good bounces on the inclined divisional surface line by line in such limited quantities and at such intervals that the jumping or bouncing as a result of the collision moving coal parts ahead of the accompanying mountain parts, but not catch up to the skip gap the remaining mountain portions of the previous line.
  • a skip of the separation gap is achieved by the coal, while the mountains come into the separation gap.
  • the DE 195 32 770 A1 indicates a continuously operable air jet screen with a fine hopper and a coarse material chute, which has a substantially flat, designed as a bottom of a closed vibrating conveyor screen surface and disposed in the fine hopper of the screen surface nozzles. Furthermore, a vibration drive for achieving a relative movement between the screen surface and the nozzles is provided. Below the Screen surface are at least two nozzles mounted transversely to the conveying direction of the vibrating conveyor fixed, wherein an oscillating air flow is passed through the nozzle on the screen surface.
  • the air flow is thereby added from below the screen mesh.
  • the airflow promotes locomotion and the cleaning effect, while locomotion is ensured by the vibration drive acting on the screen mesh. While the fines fall through the mesh of the mesh, the coarse material falls into a coarse well.
  • the present invention has for its object to provide a method and apparatus for removing dust and / or fibrous admixtures of a consisting of light hardware or plastic granules bulk material, which can be realized with extremely simple means, have high efficiency and with in a plastic processing plant usually existing facilities are feasible.
  • the object is achieved by the invention by a method as specified in claim 1, and by a cleaning device according to the teaching of claim 6.
  • the inventive method provides that the small parts or granules are not supplied in a bulk material flow of the cleaning device, as is the case with known devices, but that a separating device is connected upstream, which may be, for example, a screw conveyor, the individual small parts or granules in Row or only a few granules simultaneously. These are fed via the inlet to an inlet plate, which is opposite the inclined surface is arranged at a certain distance and / or inclination, so that the small parts or granules attract attention to the stretched or hard inclined surface and move in cracks on the inclined surface, the jump heights steadily decrease without energy.
  • This jumping behavior can be assisted or brought about by deliberately introducing an air or gas stream onto the inlet plate or onto the inclined surface in order to cause it to vibrate or to accelerate the granules through the air vortex.
  • the air can be set uniformly or entered pulsating.
  • z. B. used compressed air, coming from a compressor, for example, must be filtered in order to introduce any impurities. But it is also possible to promote the jump effect over the entire length of the housing or ensure distributed by nozzles an air flow is generated, which after lifting a granule or a small piece on the inclined surface this can lift and jump again.
  • the jumping of the individual granules can also be effected by coupling the inlet plate or the inclined surface with a vibration generator which causes the parts to vibrate.
  • the jump height should be at the first jumps greater than about 40% of the distance height between the housing top wall or cover and the inclined surface, so for example over a length of the inclined surface of about 40 to 120 cm at least seven to ten jumps. If the jumps are generated via the air supply above the inclined surface, it is possible to adjust the jumps or the jump intensity through the air supply and the alignment of the air flow.
  • the bulk material to be treated is transported via a suction conveyor in a collection container. This can be done on the one hand by removal from containers, eg by dumping bags or directly from a central supply via piping systems. Subsequently the bulk material is fed via a metering screw of the cleaning device, which consists essentially of the inclined surface within a housing and a jump generator for the individual bulk material parts. On this route, the separation of dirt particles or fibers from the bulk material to be used for further processing takes place. Likewise, the discharge of material-like abrasion takes place. The disturbing material is removed from the system via a specially shaped sieve grid of the inclined surface with the aid of a powerful suction device, which also generates the primary air, and neutralized in a filter. The now cleaned bulk material collects in a sealed container and is the downstream processing processes via sampling socket available.
  • the cleaning device has a complete seal, effective filtration systems and various sensors to assist with automatic control of interconnected device components.
  • the primary cleaning process takes place in the housing on the inclined surface and can be promoted by a Ionisationsstab.
  • the air turbulence of the air supplied on top provides for the jumps, so that when the impact of a jumping particle on the inclined surface adhering deposits are blown off.
  • the superposition of the ionization of the air promotes the bounce effect.
  • the adjustment of a flow balance using a Deckfilters in the suction ensures an adaptation to the respective bulk material or to the light hardware or to the granules.
  • the cleaned material is stored in a collecting container, which should preferably have staggered sight glasses for the filling level and sensors for automatic filling level detection and triggering of the cleaning process as required.
  • the use of known HEPA filters on the air intake prevents damaging aerosols from entering the supply air and prevents the additional entry of dust particles from the circulating air into the system.
  • the installation of oil separators and filters may be provided in the flow loop to minimize contamination in the secondary air circuit.
  • control options are possible for controlling the dosing unit and pressurizing the compressed air for optimal adaptation of the cleaning process to various types of bulk materials.
  • the operating conditions and faults can be indicated by optical or acoustic signal transmitters.
  • the whole device can be mounted in a rack or on a control box. This can have transport rollers on the bottom, so that a simple implementation as needed is also possible.
  • a stable and rigid machine frame can have damping elements for reduced dynamic load input into the environment.
  • the housing may be an elongated housing with a rectangular, edgewise cross-section.
  • the inclined surface is parallel to the ground at a distance z. B. is less than 30% of the height. In the space between the inclined surface and the bottom of the suction channel is provided.
  • the top cover runs parallel to the inclined surface.
  • the inclined position of the inclined surface is achieved by oblique installation of the housing in the machine frame and should be between about 5 degrees to about 25 degrees inclination. The skew is required to allow downward jumps of granules or hardware to reach.
  • the inclined surface can also be provided obliquely as such in the housing. In this case, the cover should also be inclined parallel to achieve such a large distance that the granules can jump freely.
  • the forced according to the inventive method jumps of the individual granules or small parts cause that the impact on the inclined surface, which is perforated or consists of a wire or plastic mesh grid and is very taut, the adhering dust particles are replaced, while the purified granules jumps again, until it reaches the end of the inclined surface and falls into an outlet section in the housing and can flow therefrom via an outlet into a collecting container, which of course must be sealed dust-tight, in order not to receive any renewed impurities.
  • a suction over the entire length of the inclined surface extending below it is provided, to which a suction device is connected, with which the contaminated with dust particles air is sucked.
  • a suction here, an industrial vacuum cleaner of the usual type has proven its suction power can be adjusted by speed control of the engine. It is thus possible to generate any desired suction force matched to the granule or small particle size and the granulate weight.
  • the air supply is usually from an existing compressor plant in an industrial enterprise using intervening filters. The air is brought over the nozzles provided on the inside of the cover. The purified, a collection container supplied granules can then be fed directly to a dryer or a distribution system or the feed containers of a plastic processing machine by means of a conveyor.
  • the air in the housing can be ionized partially or over the entire length of the inclined surface, whereby a neutralization of the electrostatic adhesion forces between granules and dust particles in a known manner, as described above, is effected. It can be seen that by the jump effect, which is exploited here for the blasting, the granules of ionized air over the time of the jump are exposed, on all sides, so that in this way a particularly high degree of effectiveness with respect to the neutralization of the electrostatic adhesive forces is given ,
  • a perforated plate with small holes or a braided wire mesh or a mesh fabric can be used. These are to be clamped so that the fabric or grid is taut and practically offers a baffle floor.
  • the Ionisationsstäbe can be provided extending over the entire length of the inclined surface in the housing.
  • the housing is a rectangular housing with a higher longitudinal than width extension with an inclined surface arranged parallel to the bottom and a suction channel underneath.

  • the housing may be installed obliquely in a machine frame. As a result, a constant distance of the inclined surface is given to the cover or to the ionization start and to the nozzles through which the air is introduced for further transport of the jumping granules.
  • an electrical control device is further provided, which is mounted on the machine frame, in order to effect the central control of all three components and the controls for air introduction.
  • the singling device can also have a metering device, for example a feed which can be operated by a setting wheel, in order to enable the continuous supply of individual granules.
  • the singulating device should be arranged above the inlet on the housing and consist in a known manner of a feed tank and a screw drive for transporting the granules from the feed tank.
  • the inclined surface may consist of a perforated plate, a braided wire mesh or a plastic mesh fabric or longitudinally and / or transversely and / or diagonal slotted sheet or plastic.
  • the slots may also be provided at defined angles to the longitudinal axis of the inclined surface.
  • the hole sizes or the gap widths are to be chosen so that the adhering to the granules particles can fall though the granules but is moved on the surface, in cracks, as indicated according to the invention.
  • the holes or the stitches of the plastic fabric or the slots can be provided throughout.
  • the inclined surface may also be divided into fields that are perforated or made of a plastic fabric with mesh or a braided wire mesh or are slotted longitudinal and / or transverse.
  • the slots may also be at an angle to the longitudinal axis. So it is for example possible to provide a perforated plate after the inlet, behind a braided wire mesh and in turn a slotted sheet metal.
  • the first field after the enema is a slotted field. This should be done together with the other fields or separately removable.
  • the slit has the advantage that hair or other longer fibers fall into or through the slits and then can be sucked down. If the first field were a hole field, then the hair ends could get caught in the holes, without them z. B. can be removed with a vacuum cleaner. Removable design of the fields makes cleaning easy. The effect is also achievable by the slit runs over the entire length of the inclined surface.
  • a rake can be integrated, which has longitudinal slots and consists of round rods. These may even be sharpened on the front side to ensure easier picking up of long fibers or hairs. This rake must also be cleaned if necessary. Through the slots or the rake is to be ruled out that longer fibers, z. B. hair, which are located in the granular stream and pass through the singulator and the inlet into the device housing, are issued with the purified granules. The slots or the rake do not interfere with the jumping of the granules per se, but pick up the ends of the long fibers. In order to facilitate cleaning of the rake or the slotted portion or the entire inclined surface, this should be removably mounted in the housing above the air duct.
  • the housing can of course also have side walls which are transparent, in order to better control the jumping of the granules and, if necessary, to be able to influence the oscillation generation or the pulsating air supply, if these assist in triggering the crack.
  • the entire cleaning process can be initiated automatically by the system's own control electronics, so that the process is stimulated as needed to avoid idling processes and supply bottlenecks in bulk material replenishment.
  • the intended for cleaning bulk material is first removed using a suction conveyor from the delivered container or a central bulk material supply and fed to the cleaning device.
  • the suction conveyor unit is designed for flexible feeding with smaller amounts of material up to 100 kg / h, but is also able to cope with short-term peak performance of up to 250 kg / h.
