Definitions

  • the invention relates to a device for treating biogenic residues, in particular compost, within a chamber, which has a conversion device equipped with a rotor and movable by means of a drive.
  • Such a device is used in practice for the treatment of biogenic waste and residual waste.
  • the treatment takes place through the use of rotting bacteria.
  • the by-products of this treatment are water, CO 2 and aggressive, malodorous vapors.
  • the process is therefore carried out in chambers, so-called rotting or compost tunnels, which are sealed off from the environment.
  • the bacteria need atmospheric oxygen and moisture, so that regular homogenization by converting the residues is necessary.
  • the rotor is used for this purpose, through which the layers of the residual material mass are implemented.
  • the transfer device is also used as a conveyor unit in a continuous tunnel.
  • the material is moved a certain distance in the direction of the exit during each transfer process.
  • the space freed up at the entrance end is filled with fresh material, so that a continuous flow of the residual substance mass is made possible.
  • the residual mass is entered into the batch tunnel in a single step, so that no new residual mass is added during the treatment.
  • the transfer device is moved into the batch tunnel for homogenization.
  • the mass of residues is initially displaced forward, similarly to the tunnel, but essentially moves back to the original position when the transfer device moves back.
  • the transfer device is coupled to a conveying device known as a discharge machine, in order to remove the entire mass of residual material from the chamber.
  • the invention has for its object to significantly simplify a device of the type mentioned.
  • the effort for the necessary protective measures against the aggressive atmosphere within the chamber is to be reduced.
  • a device is therefore provided, the rotor of which can be driven by means of a hydraulic unit arranged outside the chamber.
  • the use of an electric drive for the rotor can be dispensed with, as a result of which the outlay for the protective measures required according to the prior art is substantially reduced can be.
  • contacts and electrical control units inside the chamber can largely be dispensed with.
  • the drive of the converting device can also be driven in a particularly advantageous manner by means of the hydraulic unit.
  • the hydraulic unit can also be used to drive other movable components of the device, which can be easily supplemented even with existing devices.
  • an embodiment of the device proves to be particularly practical if the hydraulic unit is equipped with a heat exchanger for the hydraulic fluid.
  • the heat generated inside due to the treatment process can be conducted outside by means of the hydraulic fluid and removed by means of the heat exchanger.
  • temperature-sensitive components of the device can be cooled and the heat dissipated can also be used for heating other areas or for preheating other treatment chambers.
  • a process liquid which can be supplied to the residues and which is subsequently supplied to the residue mass can be heated in a particularly advantageous manner by means of the heat exchanger of the hydraulic unit.
  • the process liquid is heated to the temperature prevailing in the interior of the chamber or in the residue mass, so that the supply of the process liquid has no adverse effect, in particular no delay in the treatment process.
  • Fresh water or process water can be used for the treatment as process liquid and is fed to the treatment process in the required dosage to remain.
  • a particularly expedient embodiment of the present invention is also achieved in that the transfer device is equipped with a winding device for one or more hydraulic lines. In this way, a lowering of the hydraulic lines down to the surface of the residual material mass and thus a possible impairment or damage to the hydraulic lines is avoided.
  • the winding device for depositing unwound line sections is inclined relative to the vertical on a receptacle fixed on at least one wall surface of the chamber.
  • the unwinding direction shows for example, obliquely in the direction of the wall surface of the chamber, so that unwound sections of the hydraulic lines are deposited simultaneously with the unwinding process on the receptacles of the wall surface arranged slightly below the winding device.
  • the recordings are arranged, for example, above the level of the roadway for the drive of the transfer device and are thereby largely protected against contamination.
  • the drive is equipped with caterpillars.
  • the requirements for the properties of the road, in particular the surface quality are significantly reduced.
  • metal profiles as a tread can be dispensed with, thereby reducing the effort for the chamber.
  • Possible tolerances or gaps at transitions, especially at auxiliary points for moving the transfer device into the chamber, remain largely without an adverse influence on the functionality, whereby drives with electrical drives can also be used.
  • the chamber is equipped with guides for the drive, which are arranged opposite one another and are each arranged in a wall surface of the chamber, the surfaces of which are slightly inclined with respect to the horizontal.
  • guides for the drive which are arranged opposite one another and are each arranged in a wall surface of the chamber, the surfaces of which are slightly inclined with respect to the horizontal.
  • the guides are each formed by a projection or by a recess in the wall surface. This makes it possible to dispense with special track bodies for the drive, such as metal profiles used according to the prior art.
  • the guide designed in particular as a console, can therefore be provided with little effort during the manufacture of the chamber and does not require any subsequent installations.
  • a particularly simple embodiment of the invention is achieved in that the guides of the respective wall surface are molded on.
  • the guides can be inserted directly during the production of the wall surface of the chamber, wherein the guides can also be taken into account in the structural design of the wall thickness.
  • the guides formed in this way offer only a small contact surface for the aggressive atmosphere within the chamber resulting from the treatment of the residual mass.
  • the rotor can be moved from a working position engaging in the residual material into a rest position located above the residual material and on its end sections facing the lateral wall surfaces of the chamber, one each on the guide has a coordinated recess.
  • the recess at the end sections of the rotor allows the rest position to be shifted upward because the recesses expand the freedom of movement, which is otherwise limited by the projections of the guides.
  • the volume of space above the residual mass is reduced to a minimum. The correspondingly reduced room volume therefore creates cost advantages in exhaust air treatment.
  • the rotor can be moved from a first working position, which is positioned essentially centrally below the drive, to a further, forward-moving working position, so that residues located in the immediate vicinity of a front wall surface can be reached.
  • the forces occurring during the conversion by the rotor can be optimally introduced into the guide by means of the running gear through the central position below the running gear in the first working position.
  • the forward second working position areas in the immediate vicinity of a wall surface arranged at the end in the direction of movement of the transfer device can also be reliably reached and the residual material mass located there can be converted.
  • the chamber has a closable entry opening, to which a collecting container which is matched to the dimensions of the entry opening is assigned.
  • a collecting container which is matched to the dimensions of the entry opening is assigned.
  • the collecting container designed in this way can also be used in treatment devices known from the prior art.
  • Another particularly advantageous modification is also created by the fact that an additional barrier for temporarily closing the chamber can be moved by means of the drive. As a result, no separate undercarriage is required for the shut-off plate because it can be transported using the transfer device.
  • the entrance to the chamber is closed by the shut-off shield during the transfer process, the supply lines, for example hydraulic lines, being sealed in a corresponding recess. The undesirable escape of atmosphere from the interior of the chamber into the environment can be avoided.
  • shut-off plate can be positioned and fixed in a desired position on the guides by means of the drive, in order to avoid undesired displacement of the shut-off plate.
  • the shut-off plate is also suitable for discharging the residual substance mass, in which the shut-off plate is coupled to a discharge machine and is moved together with the transfer device over the entire length of the chamber.
  • a screw conveyor with counter-rotating screw blades is arranged within the shut-off shield.
  • shut-off shield can be closed by means of a cover. Due to the cover, the shut-off plate can be used in its closed position, in which the conveying means is protected against the residue mass, to shut off the chamber and in the open position of the cover to discharge the residue mass.
