Definitions

  • the present invention corresponds to the technical field of defibrator mills, and in particular to safety systems for them, where said mills are intended for crushing and defibration of raw materials.
  • the crushing and defibration systems of raw materials have several mills.
  • a first mill processes the entire raw material and cuts it up to a certain size.
  • a second mill picks up the product processed by the first mill, and cuts it back to a smaller size.
  • a third mill is responsible for collecting the product of the second mill and defibrating it so that it is able to extract its sugars.
  • the applicant has managed to define a new, more economical and compact defibrator mill, capable of cutting and defibrating raw materials efficiently.
  • This mill has a hopper for the entry of products and a housing inside which has a first and second disc connected to a rotation motor.
  • the raw material When the raw material enters the equipment, it is found with at least one blade attached to the first disk and a cavity of the cut material towards the space between both discs.
  • the blades rotate with the entire system and chop the material until the slices have the predetermined size determined previously and pass to the other side of the first disc through the openings made in it.
  • perimeter blades continue to cut the product while chains are responsible for the defibration of the same.
  • This new shredder mill simplifies and replaces the train of mills that have usually been used in the industry for these crushing and shredding works, which entails an important economic benefit by having to install only one equipment instead of the equipment train that is coming employing in the industry, which reduces supervision needs, necessary personnel, investment, maintenance costs, etc.
  • the safety systems for shredder mill presented here are directed to mills intended for crushing and shredding of raw materials comprising a hopper for the entry of products and a first and second disk connected to a rotation motor, where said first disc has at least one blade and an opening towards the space between said first and second disc, where chains run to defibrate the product.
  • Said systems comprise a protective housing of the first and second discs, as well as of the at least one blade thereof, which has a cylindrical shape with two circular bases suitable for covering one of the discs respectively and a curved surface between them, and at least an opening and closing lid in an area upper curved surface.
  • They also comprise a hydraulic arm connected to the housing and capable of producing the lifting of the at least one opening and closing lid thereof.
  • the safety means have a motion sensor capable of preventing the opening of the at least one opening and closing lid when the rotation motor is in operation, and fixing means of the discs suitable for preventing the movement of rotation thereof when the at least one opening and closing lid is in the open position.

  • These mills (1) as can be seen in Figures 1, 3.1 and 3.2, comprise a hopper (2) for the entry of products, a first and second disk (5.1, 5.2) connected to a rotation motor, where said first disc (5.1) has at least one blade (6) and an opening (7) towards the space between said first and second disc (5.1, 5.2), where chains (8) run to defibrate the product.
  • the safety systems comprise a protective housing (3) of the first and second discs (5.1, 5.2) as well as of the at least one blade (6) thereof, a hydraulic arm ( 4) connected to the housing (3), a motion sensor and means for fixing the discs.
  • the protective housing (3) as shown in Figure 1 has a cylindrical shape with two circular bases suitable for covering one of the discs respectively and a curved surface between them.
  • This housing (3) prevents the pieces of product from being fired due to the centrifugal rotational force generated during the defibration process, so that they remain contained within the mill (1) and do not present any danger. If this housing (3) does not exist, the product pieces would be thrown due to said centrifugal force, in any direction, and could impact on people or objects.

  • the motion sensor of the safety means is suitable to prevent opening of said cover (9) for opening and closing the housing (3), when the rotation motor is running.
  • said motion sensor is connected to the axis of the rotation motor so that, the motion sensor detects if the axis is in rotation and therefore if the disks (5.1, 5.2) and The blades (6) are rotating.
  • the sensor detects that the assembly is rotating, it does not allow the opening of the housing cover.
  • the fixing means of the discs (5.1, 5.2) are suitable to prevent the movement of rotation thereof when said opening and closing cover (9) is in the open position.
  • these fixing means (not shown in the Figures) isiide the discs are formed by a safety latch and an opening capable of immobilizing the rotation motor when the latch is arranged internally to said opening.
  • Both the housing (3) and the safety latch, in this preferred embodiment of the invention, are made of carbon steel, while the hydraulic arm (4) is formed by a stainless steel cylinder.
  • the shredder mill is provided with systems that make it much safer, avoiding personal and material damage and ensuring that the operation and maintenance of the equipment are adequate, correct and safe.
  • the housing prevents the product from firing strongly in any direction, so that possible impacts and unwanted damage are being avoided, both to people and objects. And it also ensures that access to the interior of the mill is not possible when it is in rotation, so that damage to the operators is avoided, ensuring that maintenance and repair work is safe and comfortable.
  • the hydraulic arm allows the opening and closing of the housing cover, facilitating said work for the operators.
