Definitions

  • the present invention is encompassed within the technical field of the sorting, selection or separation of heterogeneous solid elements, based on their dimensions or volume. It refers to elements received in a grouped manner that cannot be easily selected or differentiated, and therefore, it is sought to achieve their separation and selection for different subsequent processes, for example, recycling processes of various waste materials. Solid element separation is required in multiple industries, such as recycling, food, mining, etc.
  • objects of the present invention are a device for separating elements, as well as a method for the same purpose, in which the grouped heterogeneous elements are separated thanks to the diversity of sizes or volumes that differentiates one from another between them.
  • the separation is achieved in a reduced space, without excessive noise and does not require vibration, in addition, it requires a minimum displacement of its parts and low energy consumption.
  • conveyor means configured to support and transfer a heterogeneous group of elements of different sizes to be separated.
  • These conveyor means comprise a plurality of traction belts arranged so that a plurality of spaces are formed therebetween. Where, these spaces created between the traction belts gradually increase and act as separation means of the elements conveyed by said belts, according to the dimensions of said elements, as shown in documents CN211515211 , KR101430146 , KR100861742 , US1552366 and US3779379 ; or else, aided by second belts arranged between the traction belts, usually in a lower plane of the latter, as shown in documents CN2167069 and US3713537 .
  • An object of the invention is a device for separating elements based on their dimensions.
  • the device basically comprises:
  • the conveyor means comprise a plurality of traction belts arranged in parallel, such that a plurality of spaces are formed between the traction belts.
  • the separation means comprise at least a first array of elevation columns with first rows of vertical columns.
  • the first rows of vertical columns are extended below the conveyor means, where the first array of elevation columns is adapted to be moved vertically, such that the first rows of columns are suitable to be raised, passing through the spaces formed between the traction belts of the conveyor means, and to come into contact with the elements of greater dimensions of the group of elements to be separated, where a distance between the first rows of columns is smaller than some dimensions of the elements of greater dimensions and greater than some dimensions of the rest of the elements of the group of elements to be separated, such that, when raising the first rows of columns, the elements of greater dimensions are raised and separated from the rest of the elements of the group of elements to be separated, which remain supported on the traction belts.
  • the separation means of the device can comprise more than one array of elevation columns, from one to n, depending on the number of separation steps that are required to be implemented for the group of elements to be separated based on their dimensions. For example, in a preferred embodiment, first, those of greater dimensions, then, those of intermediate dimensions and, lastly, those of small dimensions.
  • the separation means additionally comprise a second array of elevation columns with second rows of vertical columns likewise extended below the conveyor means, where the first and second rows of columns are alternately arranged in a staggered formation, and the first and second arrays of elevation columns are adapted to be moved vertically and independently of each other, such that, in a second separation step, the second rows of columns are suitable to be raised, passing through the respective spaces of those formed between the traction belts, alternating with the spaces already passed through by the first rows of columns, and to come into contact with elements of intermediate dimensions of the group of elements to be separated, where, a distance between the first and second rows of columns is smaller than the dimensions of the elements of intermediate dimensions and greater than the dimensions of some elements of small dimensions, such that, as the first and second rows of columns are raised, the elements of intermediate dimensions are raised and separated from the elements of small dimensions, which remain supported on the traction belts.
  • the respective first and second rows of columns of the first and second arrays of elevation columns are adapted to be independently raised and to come into contact with the elements of greater and intermediate dimensions of the group of elements to be separated, where, a distance between the first rows of columns is smaller than some dimensions of the elements of greater dimensions and greater than some dimensions of the elements of intermediate dimensions, and a distance between the first and second rows of columns is smaller than the dimensions of the elements of intermediate dimensions and greater than some dimensions of the elements of small dimensions, such that, when raising the first rows of columns, the elements of greater dimensions are raised and separated from the elements of intermediate and small dimensions, and when lifting the first and second rows of columns, the elements of intermediate dimensions are raised and separated from the elements of small dimensions, the latter remain supported on the traction belts.
  • an object of the present invention is a method for separating elements based on their dimensions.
  • the basis is to support and transfer grouped elements to be separated, on a collection platform, on conveyor means with a plurality of traction belts arranged parallel to each other, such that a plurality of spaces are formed between the traction belts.
  • first rows of columns of a first array of elevation columns are elevated, through respective spaces of those formed between the traction belts, until pushing the elements of greater dimensions towards a height, arranged above the collection platform, wherein the elements of greater dimensions are separated from the rest of the elements of the group of elements to be separated, which remain supported on the traction belts.
  • the first rows of columns are lowered to the level of the collection platform, and finally, the rest of the elements of the group of elements that are supported on the traction belts and/or the collection platform are removed, and it is possible to start a new cycle of the separation method of a new group of heterogeneous elements to be separated based on their dimensions.
  • the method could include more separation steps in addition to the basic ones described above.
  • second rows of columns are elevated from a second array of elevation columns, through respective spaces of those formed between the traction belts, alternating with the spaces already passed through by the first rows of columns, until pushing some elements of intermediate dimensions, from the group of elements to be separated that remained supported on the traction belts after the separation of the elements of greater dimensions, towards the height previously reached by the first rows of columns, wherein the elements of intermediate dimensions are separated from the rest of the elements of small dimensions, which remain supported on the traction belts.
