Definitions

  • the invention concerns a device intended for the compression of materials such as plastic waste, paper and bulky waste such as produced by fast-food shops.
  • materials such as plastic waste, paper and bulky waste such as produced by fast-food shops.
  • a large amount of air is trapped between the layers of waste causing an unfavourable volume/weight ratio during transport and storage.
  • This waste it is first collected into an airtight package, such as a plastic bag, and is then compressed with the aid of the device.
  • compression of waste material has been done by means of a mechanical press as described in the Dutch patent specification no. 8200548.
  • the disadvantage of this press is that it is very expensive.
  • the problem of the material taking on its original volume again having been compressed is not entirely solved by the present-day methods of compression.
  • the waste packaging is bound together but small loose pieces of the material are not kept together with the main bulk or otherwise they are lost or hang out. Extra packaging is necessary in order to prevent this.
  • Another disadvantage is that with polluted waste, for example from fast-food shops, liquid or partially-liquid substances are squeezed from the packaging.
  • a second method of compression is to create pressure around the plastic packaging containing the material as described in the WO patent specification no. 88/03892.
  • the disadvantages of this method are the large dimensions of the machines, its unpractical operation and the fact that the material is compressed to an uneven package.
  • the problem of preventing the material regaining its original volume is only partially solved. This can only occur if the plastic packaging remains airtight, a condition which is hardly ever attainable when handling waste. Extra packing or provisions are necessary in this case. If one intends to reduce the volume of a plastic bag of material by vacuum suction the following problems are encountered:
  • a seal has to be created between the bag and the suction device which will remain airtight during the vacuum process but which will still allow the suction part to be removed without the bag regaining its original volume when it has been secured.
  • the aim of the invention is to provide a compression device able to compress waste material or other voluminous products to one quarter of their original volume but which does not have the disadvantages mentioned.
  • both these pipes are brought together in an airflow reversal appliance. This makes it possible, by way of a simple hand-grip, to revert the airflow in the air-pipe connected to it. This means reverting the outgoing airflow into incoming airflow and vice versa.
  • the airpipe in which the airflow can be reverted ends in a locking device.
  • a cylinder-formed part a bag-sealing cylinder, is used to which the locking device is connected.
  • the outside of the cylinder is covered with flexible material such as rubber.
  • the cylinder has three valves.
  • the bag is secured around the cylinder-formed part. By allowing the air to flow out of the suction-and-compression hose with the aid of the airflow-reversal appliance, the airflow is blocked by a valve and the space between the flexible material and the cylinder is inflated. The diameter then increases closing the opening of the bag tied around.
  • the actual suction part connected to the aforementioned cylinder consists of a flexible flat disc whose upper layer is made of smooth material and lower layer of porous tissue whilst the diameter is approximately the same as that of the opened waste bag.
  • Spiral springs are fixed in a radial form at regular distances between these two layers which, because they do not press together, convey the air entering the porous material to the cylinder part. In this way the aim of sucking in air over the entire surface is achieved, whereby the bag is evenly reduced in size and takes on a manageable shape whilst at the same time preventing blockages.
  • the airflow reversal appliance in fig. II consists of a smooth pipe (1), hermetically sealed in the middle by seal (2). There are several holes (3a and 3b) on either side of the seal. One side of the pipe is connected to the suction part of the pump and the other to the compression part. Both sides of the pipe have a ridged part (4).
  • the air reversal housing (5) is connected around the pipe between these ridges. This housing consists of a pipe cut to an angle at both ends and has a culvert (6) where the suction-and-compression hose (8) is connected and whereby two air-seals (7) ensure the pipe is airtight. By turning the reversal housing (5) from left to right and vice versa, it moves up and down. In this way both the upper openings (3a) and the lower openings (3b) come in turn in the smooth pipe (1) inside the air-seals (7) on the housing thus reversing the airflow direction in the suction-and-compression hose (8)
  • the bag-sealing cylinder (fig. III and IV) consists of a cylinder (10) covered on the outside with flexible material (11) and is equipped with valves (12, 13, 14).
  • the locking device (9) is brought in the cylinder (10) and turned 10 degrees to the left and anchored by the ridges (15).
  • valve (12) closes, valve (13) opens and the outer flexible band (11) is then inflated. If the airflow is now reversed then the cylinder acts as an air-conveyor.
  • valve (14) is pressed in by the outer wall of the locking device (9) causing the air between the afore-mentioned cylinder and the flexible material to escape.
  • the suction piece (16) in fig. III, IV and V consists of a flat rubber disc whose upper layer consists of smooth material and lower layer of porous tissue. Spiral springs (17) are fixed in a radial form between these two layers. By fixing the ends of the springs (17) around the ring (18) they become hinged.
