Definitions

  • the invention relates to a medical waste shredding system, consisting of a coherent, multi-section housing, which in its upper area contains a shredder with a subsequent slide shaft for guiding the shredded material in a separator, the separator being provided for separating the liquid and the solids is, and wherein the housing is fixed by a stand at a height that allows the replacement of the waste containers.
  • a waste crushing plant of the type mentioned is known from US-A-4 759 508.
  • a conveyor unit is arranged below the comminution unit, which consists of two screen surfaces arranged at a distance from one another, which are set in a vibrating motion by a motor.
  • the material comminuted with the known system - it is a glass container, such as ampoules - is conveyed by the comminutor via the transport unit to a collecting drum arranged to the side of the comminution system and removed there from the system via an elastic connecting pipe. As soon as the collecting container is filled, the elastic connecting pipe is pulled upwards and the filled container is replaced by a new collecting container.
  • the object of the present invention is to provide a compact shredder for medical waste, with which the solids are transferred into a low-void mixture with the greatest possible prevention of dust escaping into the atmosphere and with which the exchange of the vessels is simplified.
  • the solution according to the invention essentially consists in that a shredder with a subsequent slide shaft for guiding the shredded material into a separator is arranged in a coherent, but consisting of several sections housing in its upper region, the separator being provided for separating the liquid and the solids and being stored on the floor of the housing and each have an outlet for the liquid and solids, and the housing is fixed by a stand at a height which enables the replacement of the waste containers.
  • waste material prepared in this way can - as a rule, ie insofar as it is not infectious - be taken up by household waste disposal, although a further reduction in volume can be achieved by the following processes.
  • a pyrolytic aftertreatment should be considered here in particular.
  • the drive system uses a continuously guided shaft to drive a horizontally structured twin-shaft shredder and a centrifuge-type separator that is driven perpendicular to it in a housing. Furthermore, in alignment with the storage of the separator base in the housing base, a turntable arranged for the multiple installation of liquid and solid vessels is provided, which after filling by swiveling out of the vessels sometimes carries out a closure, e.g. B. a welded closure.
  • a closure e.g. B. a welded closure.
  • this has a pot-like edge still drawn upwards and a truncated cone-shaped sieve is concentrically connected to the bottom, into which the slide shaft opens and in which, directed towards the inner sieve surface of the sieve, a scraper lifting off the solid layer is connected a stationary first outlet for the solids provided in the inclined housing base and the peripheral region of the separator base forms a sieve part into which the second outlet for the liquid provided in the inclined housing base opens.
  • a device for surface treatment of the shredded material is provided to suppress the development of dust and for disinfection in the area of the shredder, leading into the separator, which device permits safe storage of the medical waste thus processed as domestic waste.
  • the waste comminution system 1 is essentially constructed in a housing 2 consisting of several sections. In the upper area of this housing 2 there is a double-shaft positive shredder 3, the shredding shafts 3.1 of which are connected by a spur gear pair 3.2. One of the emerging shafts 3.3 carries a relatively large ring gear 3.4 for the drive described later.
  • the comminuted material leads through a slide shaft 4 into the separator 5, which is delimited by a pot-like edge 5.1.
  • the separator bottom 5.2 carries a concentrically arranged, truncated cone-shaped sieve 5.3, the remaining peripheral bottom region 5.5 also being formed with an annular sieve part 5.4.
  • the frustoconical sieve 5.3 takes over the function of the separating sieve.
  • the solid parts are deposited on the inward inclination of the sieve surface and are removed from the wall by a lifting scraper 4.1 and passed through the opening 5.5 in the separator base 5.2 into the outlet 2.5 for the solids. Due to the centrifugal force, the liquid is further displaced by the conical sieve 5.3, deposited on the pot-like edge 5.1 and separated out via the outlet 2.4 to the liquid vessel 6.3 via the annular sieve part 5.4 which is arranged flat in the bottom.
  • the vessels 6.3 and 6.4 used are appropriately designed in their upper edge area for the arrangement of a plastic weld closure.
  • the drive motor 7 is provided, which, via an output shaft 7.1, first enables the bevel gear pinion 7.2 for the drive of the ring gear 3.4 and, in its extension, the drive of the face or friction wheel 7.3.
  • This wheel 7.3 engages in a front or friction ring 8 comprising the separator 5.
  • a turntable 9 is provided below the centers of the separator 5, for the installation of the vessels 6.3 and 6.4, the description of this detail being omitted.
  • a device 10 for surface treatment of the shredded parts opens, with the aim of largely suppressing the formation of dust and reducing the risk of infection to a minimum.
  • the housing 2 is carried by the stand 2.1 at a distance which enables the manipulation of the vessels 6.3 and 6.4, namely by three blocks 11 on a worktop.
