Device for compacting bio-harmful waste

The present invention relates to a device for compacting in closed sheet metal containers located solid bio-harmful, in particular radioactive waste, consisting of a closed Containment with pollen conveyors and other transport elements, a container channel, a high-pressure press and a container rejector with a collecting container.

There is a disposal of solid bio-hazardous waste, especially solid radioactive waste the task of narrowing the waste volumes so far that the smallest possible storage volume is required, without toxic or radioactive components being released during treatment or storage. Solid wastes to be treated in this way fall in the chemical industry, in the petrochemical industry, in the medical and pharmaceutical sector, in research facilities, hospitals and in nuclear technology.

Packing presses, for example, are used to reduce the volume of waste. Such compacting devices are described in DE-OS 2 639 691, in DE-PS 2 2 ^ 3 136 and in Cheroie-Ing.-Techn. k2 year, 1970, number 9 / iO, pages 6 ^ 9 and 65O, described. High-pressure presses are also known with which waste containers are compacted together with their waste contents.

Some of these compacting devices have the disadvantage the largely open delivery and treatment of waste, trsils the disadvantage of a very expensive Superstructure. Therefore, such systems are e.g. for variable mobile use at garbage cans and at unsuitable for regular disposal in the chemical and nuclear industry.

The present invention was therefore based on the object of providing a device for compacting in closed Solid, bio-harmful, in particular radioactive, waste located in sheet metal containers, consisting of a closed Containment with roller conveyors and other transport elements, a container infeed, a High pressure press and a container discharge with collecting container, to create that are safe to use anywhere, environmentally friendly and, if necessary, mobile, and can be handled easily and safely, and to supply facilities which are present in each case is connectable.

The object of the invention has been achieved in that the container sluice can be rotated about the vertical axis is, with a hydraulic cylinder for transporting the sheet metal containers into the high-pressure press and with an in Normally located within the roller conveyor, liftable hydraulic cylinders for ejecting the deformed ones Sheet metal container from the high pressure press is provided, and a movable gripping element for the deformed sheet metal container is arranged above the container discharge.

The containment is an advantageous embodiment with a connection for the supply of solidifying agents Mistake. With this connection it is possible

hydraulically solidifying binders in the deformed sheet metal container containing collection or final storage container to promote.

The device according to the invention and other particularly advantageous configurations are described in more detail below _{by way of example with reference to the schematic illustrations I 1 Ii and III.}

The device according to the invention consists of a base frame (i) on which a container inlet (2), a high pressure press (3) and a container outlet (h) are arranged. \ sn base frame (i) are also attached lifting lugs (2 ^). Furthermore, pods can also be attached to the base frame (1).

The container inlet (2), part of the high pressure press (3) »A compact pusher consisting of a lying in the normal position within a roller conveyor (io) liftable cylinder (5)> and a container direction, consisting of a hydraulic cylinder (6), are located in a joint vented containment (7) · Keeping the containment slightly lower (7) is advantageously carried out with the help of a suction ™ fan (8) mix upstream absolute filter (9) is reached. This may make a delivery more contaminated Air to the not far prevented. The substructure of the device according to the invention attached to the base frame (0 is advantageous as a collecting tray with 3un> pf trigger ("i2) trained, especially for Aaffangen and Saro- ' mine of decontamination fluids that are

incurred. The container to be pressed is a closed one 200 1-sheet metal drum (13), but can also be done differently be designed. The sheet metal barrel (13) contains solid

Waste such as radioactively contaminated components, gloves, chemical toxins, in pieces or in bulk with a corresponding looser volume. The sheet metal barrel (i3) is placed on a roller conveyor (10) with a forklift or the like and rolled into the container feeder (2) up to the hydraulic cylinder (6). D at _a is the rotatable Behältereinschleuse (2) in the open and from the outside baschickbarer position vobei the containment (7) is closed by the opposite lock the inlet lock side. Outside the containment (7) is a

Lock rotary drive (25) arranged. 15th

Then the container lock (2) with the sheet metal barrel (13) is rotated 180 ° so that the lock opening is opposite the high pressure press (3). The hydraulic cylinder (6) now pushes the metal barrel (i3) under the plunger of the baler (3) · ^The baler (3) is a known self-supporting structure, which is designed according to the invention application. The hydraulic unit of the press (3) is in addition to the inventive

2 ~ - set up the device outside the container rent (7) and connected to the press via couplings. The press (3) is cliraubt with the basic frame (i), likewise the press jacket by means of tie rods (i'O

After the pressing process, the deformed container (T 5), ie the former sheet metal barrel (13) now compacted together with its waste contents, is pushed out of the pressing position into a receiving position within the discharge unit (k) below a movable gripping element (17). This is done by means of the hydraulic cylinder (5), which in its standard position in the divided roller

track (ΐθ) housed inside the container lock (2) and is first lifted into the required working position with the help of a lifting cylinder (left).

The gripping element (i7) grips with its three-cam gripper, which is actuated via a hydraulic cylinder (18), the deformed container (15), lifts it by means of the Hubzy-TO linder (16) and positions it by means of a trolley (19) over a collecting container (27) 1, for example a 400 i-Blecr.f ass. The gripping element (17) can in some cases also consist of an electromagnet.

The collecting container (27) can be lowered via a Protective hood (lO), the hydraulic cylinder (21) can be moved tightly with the inventive Device connected. The containment (7) which is closed on all sides is therefore particularly advantageous in this way ensured. After swiveling aside a swivel plate (22) which is attached to the protective hood (2θ) is, the deformed container (15) can now be introduced into the collecting container (27). After this Filling the collecting container (27) with the desired Number of deformed containers (15) can be included in the Collecting container (27) remaining empty lumps with solidifying agents fill out. It is particularly advantageous to use the device according to the invention with a Connection (r6) to be provided for the supply of bitumen or hydraulically solidifying binding agents.

This makes it possible to find the empty volume on the spot between the deformed containers (15) and the collecting container (27) to be filled with concrete, for example. Particularly it is beneficial to

collecting container (27) to arrange a vibrator (23), the effectively supports the correct filling of the empty volume.

After filling the collecting container serving as storage barrel (27) with deformed containers (I5) and possibly the filling of the empty volume with concrete or the like, the swivel plate (22) is in his Pivoted starting position. The now released Storage barrel (2?) Is then closed by a Forklift lifted from the device according to the invention and, if necessary, to a binding station and later brought to a warehouse.

Below the gripping element (1?) There can also be :, a Roller conveyor (28) can be arranged. However, it has proven to be advantageous to use a turntable at this point (29) to be attached, the one with several deformed Blech.behältern (15) can be charged. This makes it possible Deformed via a height measuring device (30) for ice Container (15) »a weighing device (32) and a

Turntable drive (31) to select the container (15) for filling the collecting container (27) so that each one optimal volume is used. A computer selects those containers (15) that are suitable for one optimal filling are required.

The device according to the invention is compact by its The structure can also be easily transported, thanks to coordinated drives for the workflow and possible mutual interlocking of important functions such as lock actuation, press and concrete feed, can be operated easily and safely from outside.
