Definitions

  • the invention relates to a hydraulically driven, vertically operating press for compacting solid waste contained in containers, consisting of a frame with a stationary table and head piece, a press cylinder, a press piston guided therein with a stamp attached to it, a piston rod and a lifting rod. and lowerable, consisting of a tube bale chamber, which is guided in the frame.
  • Hydraulic presses are increasingly used to reduce the volume of solid waste that is stored in metal containers or metal drums. This is often hazardous waste generated in the chemical industry, in research institutes and in hospitals. Solid radioactive contaminated special waste in particular, which is generated primarily in nuclear facilities, must be compacted before further conditioning, additional packaging and landfilling. This is often done by compressing closed 100 liter metal drums filled with waste into tablet-like "compact", which in turn is stored in larger landfill drums e.g. can be accommodated in 200 1-metal drums. This compacting is usually carried out with hydraulic high-pressure presses.
  • D E -OS 26 59 691 is a hydraulically reasonable t rubbed, vertically operating press for compacting located in containers of radioactive waste described, consisting of a fixed table and head piece, a pressing cylinder with pressing piston and affixed stamp according to the preamble of claim 1.
  • this press due to its constructive design, this press has a very high dead weight and a very large space and space requirement. This largely prevents mobile use of this press, and the accommodation of such presses is particularly complex because of the required space, which is expensive anyway for safety and contamination reasons. Disposition, maintenance and decontamination of such large presses, as well as the necessary additional protective measures, such as. B. against contamination of the operating personnel.
  • the present invention was therefore based on the object to provide a hydraulically driven, vertically working press for compacting solid waste contained in containers, consisting of a frame with a stationary table and head piece, a press cylinder, a press piston guided therein with a stamp attached to it , a piston rod and a lifting and lowering, consisting of a tube compression chamber, which is guided in the frame, which has a low weight, requires little space and space, is low-maintenance and ensures safe work without endangering the operating personnel.
  • the press cylinder forms the frame, on the head piece of which the piston rod is fixed, that the press chamber is guided in the press cylinder and the ram in the press chamber, and that the press cylinder in the lower half has at least one loading and Has emptying opening.
  • the press cylinder is preferably provided with reinforcing ribs.
  • the designed as a base plate table (2) of the hydraulic press is frictionally connected with the head piece (3) by means of the P reßzylinders (1).
  • the press cylinder (1) can have one or two loading openings (27) for the press chamber (25), in which there is a sheet metal drum (26) filled with waste, which to be pressed into a tablet-shaped "compact".
  • the loading openings (27) can be provided with an opening transverse reinforcement (22) and can be delimited laterally by guide reinforcements (17).
  • the press cylinder (1) can consist of cast iron, cast steel or another suitable material.
  • the wall thickness of the press cylinder (1) is designed according to the press pressure.
  • the head piece (3) is firmly connected to a piston rod (10) by a threaded nut (11).
  • Hydraulic lines (29) lead through the head piece (3) into a hydraulic chamber (30) via hydraulic unit connections (28).
  • the hydraulic fluid presses on the piston cover (8), on which the plunger (6) is attached to the plunger base (7).
  • the plunger (6) is guided over the piston cover (8) along the piston rod (10) inside and also over the piston cover (8) equipped with sealing elements (12) and guide elements (23) on the inside of the press cylinder (1) and supported.
  • the plunger (6) on the guide ring (34) of a pressure plate (15) attached to the plunger base (7) is guided in a press chamber (4) which forms the press chamber (25).
  • the press chamber (4) is moved axially by means of the hydraulic auxiliary cylinders (13).
  • the press chamber (4) is guided or supported at the top by means of a support ring (5) and at the bottom via bearings (14) of the guide reinforcements (17) located on the press cylinder (1) in the press cylinder (1) (Fig. VII). Due to the double guidance of the plunger (6) and the bale chamber (4), which also has to absorb the lateral press forces when compacting the pressed material, and the long selected guide distances "C” and "D", the plunger (6 ) locked out. Through his Support function, the support ring (5) prevents the press cylinder (1) from constricting in the lower region of the loading openings (27).
  • the hydraulic chamber (30) is connected to the annular space (31) which is delimited by the press piston (6) and the piston rod (10).
  • the annular space (31) thus acts as an additional press cylinder, so that the hydraulically effective total piston surface now consists of the piston cover (8) plus piston crown (7). This results in a low operating pressure with maximum pressing force. It is also possible to do without the piston rod (10) (Fig. III b), especially for smaller presses.
  • the pressure plate (15) attached to the underside of the piston head (7) in the direction of the material to be pressed is expediently curved.
  • a correspondingly shaped support (20) is attached to the table (2). The resulting greater compression of the compact near its axis reduces its divergence after the compacting process.
  • the lower inner wall of the press chamber (4) is lined with a replaceable, hardened wear insert (21).
  • the V erschl constitutiondium (21) is constructed suitably slightly conical to facilitate the removal of the compression chamber (4) from the compact (33).
  • the height of the V erschl constitutiondes (21) is dimensioned such that it can absorb the lateral pressure during the pressing or Kompakt istsvorganges.
  • the pressure plate (15) and the support (20) can advantageously also be made of replaceable, low-wear material. However, it is also possible to insert the support (20) into the table (2) so that the flat upper edge of the support (20) coincides with the upper edge of the table (2).
  • Perforation devices (18) for producing ventilation holes in the not yet compacted drums (26) are arranged on the press.
  • the drums (26) can by means of rollers or sliding plates (16) in the P RESS are brought position.
  • the press cylinder (1) is provided with reinforcing ribs (9). These can e.g. B. welded or cast. It has also turned out to be advantageous, above all for assembly and maintenance reasons, if the press cylinder (1) is connected to the table (2) and the head piece (3) by screws (19).
  • the loading openings (27) can optionally be equipped with a suction device which, after the compression chamber (4) has been lifted, removes any contamination after the compacting has been carried out.
  • the pressing process using the press according to the invention will be explained below.
  • the pressing or compacting process is started by opening the hydraulic connection (32) and flooding the hydraulic chamber (30) with hydraulic oil via the connections ( 28) and the channels (29) initiated.
  • the flooding is started with a high volume flow at low pressure.
  • the hydraulic pressure reßwiderstand automatically until it reaches the maximum operating pressure.
  • the oil escapes from the room via the connection (32), the plunger (6) plunges into the press chamber (25) and compresses the barrel (26) into a tablet-like compact (33).
  • the press chambers (4) and the press pistons (6) can be returned to the output or Loading position. This can be done either by pumping out the hydraulic chamber (30) according to Figure III b or by flooding the room (31) according to Figure III a.
  • the press cylinder (1) together with the press chamber (4) in the press position, also provides an effective, closed containment to the material to be pressed and thus also offers excellent contamination protection for the operating personnel.
  • the press according to the invention can be operated remotely and can be used inexpensively in hot cells and similar rooms.
  • the press according to the invention can be used by adapting the press piston (6) and the press chamber (4) with the end of an adapter for compacting differently sized pressed material.
