Refrigerator dismantling method, compression equipment, and refrigerator dismantling device

A compressing device comprising:

• at least a pair of compression rollers opposing each other for compressing/processing an object to be compressed;
• a gas diffusion preventing device for preventing a diffusion of a gas leaking from the object to be compressed during compressing;
• and
• a gas collecting device for collecting the gas.

A device for disassembling a refrigerator comprising:

• a cutting device for cutting/processing a heat-insulating housing of a refrigerator including a heat insulator into a plurality of pieces;
• and
• a compressing device for compressing/processing the pieces with compression rollers opposing each other so as to collect a gas contained in the heat insulator;
• wherein the cutting device comprises
• a rotor with a principal plane,
• a spindle provided in a normal direction to the principal plane, and
• at least one impacting body mounted on the spindle rotatably,
• wherein the impacting body is mounted so that a predetermined fitting gap is provided between the impacting body and the spindle and a part of a periphery of the impacting body can be positioned beyond a periphery of the rotor, and
• the rotor is rotated at a high speed to allow the impacting body to impact on the heat-insulating housing at least at a critical impact velocity.

• and
• a compressing device for compressing/processing the pieces with compression rollers opposing each other so as to collect a gas contained in the heat insulator;
• wherein the cutting device comprises at least a first rotating unit and a second rotating unit, each of these rotating units comprising
• a rotor with a principal plane,
• a spindle provided in a normal direction to the principal plane, and
• at least one impacting body mounted on the spindle rotatably,
• wherein the impacting body is mounted so that a predetermined fitting gap is provided between the impacting body and the spindle and a part of a periphery of the impacting body can be positioned beyond a periphery of the rotor,
• the impacting body of the first rotating unit and the impacting body of the second rotating unit impact on the heat-insulating housing sequentially while the rotating units are rotated in a plane parallel with the principal plane of the rotor at a high speed and the first and second rotating units are held so that a circular path of a tip of the impacting body of the first rotating unit and a circular path of a tip of the impacting body of the second rotating unit during the rotation substantially are on the same plane,
• a cutting depth by the impacting body of the second rotating unit is larger than that by the impacting body of the first rotating unit, and
• the impacting body of at least one of the rotating units impacts on the heat-insulating housing at least at a critical impact velocity,
• whereby the heat-insulating housing is cut in a direction substantially parallel with the principal plane of the rotor.
