Systems, devices and methods for screening industrial products
Systems, devices and methods for screening materials or industrial products, such as foundry coke, are disclosed herein. In some embodiments, representative systems and/or devices can include (i) a plurality of screening members each extending along a first axis, wherein the screening members are configured to make contact with a material to be screened, (ii) a plurality of elevating members extending along the first axis, wherein individual elevating member are coupled to a lower portion of corresponding individual screening members, and (iii) a cross support extending along a second axis angled relative to the first axis, wherein the cross support is coupled to a lower portion of at least some of the elevating members.
1 . A device for screening industrial products, comprising:
a filtering device comprising a plurality of screening elements and a cross support coupled to at least some of the plurality of screening elements, wherein;
each of the plurality of screening elements includes a first portion and a second portion coupled to a lower region of the first portion,
the first portion is made of metal and has a substantially circular cross-section,
the first portion has a first cross-sectional dimension and the second portion has a second cross-sectional dimension less than the first cross-sectional dimension, and
each of the plurality of screening elements is spaced apart from an adjacent screening element by at least 0.1 inch;
a waste shield coupled to a distal edge of and positioned underneath the filtering device wherein each of the filtering device and the waste shield is configured to be oriented at a non-horizontal angle, and wherein the waste shield is configured to direct small industrial products falling through the filtering device toward a waste pile;
a loading belt positioned at or adjacent to a proximal edge of the filtering device;
a first pipe extending along a length of the loading belt;
a first spray nozzle coupled to a distal end of the first pipe, wherein the first spray nozzle is configured to spray a deicing fluid onto the small industrial products directed toward the waste pile by the waste shield;
a second pipe in fluid communication with the first pipe; and
a second spray nozzle coupled to the second pipe, wherein the second spray nozzle is configured to spray the deicing fluid onto industrial products carried by the loading belt.
2 . The device of claim 1 , wherein each of the first portions of the plurality of screening elements is spaced apart from an adjacent first portion by a first distance, and wherein each of the second portions of the plurality of screening elements is spaced apart from an adjacent second portion by a second distance greater than the first distance.
3 . The device of claim 1 , wherein the plurality of screening elements is disposed at an angle of 30-80 degrees relative to a direction of gravity such that the industrial products travel over the plurality of screening elements due to gravity.
4 . The device of claim 1 , wherein the plurality of screening elements is configured to allow a portion of the industrial products to fall in between individual screening elements when traveling over the plurality of screening elements.
5 . The device of claim 1 , wherein the second portion is configured to separate the first portion and the cross support by a distance of at least 1 inch such that the industrial products traveling over the plurality of screening elements do not contact the cross support.
6 . A method of screening a material, comprising:
providing a filtering device including a plurality of screening elements and a cross support coupled to at least some of the plurality of screening elements, wherein each of the plurality of screening elements includes a first portion and a second portion coupled to a lower region of the first portion, wherein the first portion is made of metal and has a substantially circular cross-section, wherein the first portion has a first cross-sectional dimension and the second portion has a second cross-sectional dimension less than the first cross-sectional dimension, and wherein each of the plurality of screening elements is spaced apart from an adjacent screening element by a distance of at least 0.1 inch;
providing (i) a waste shield coupled to a distal edge of and positioned underneath the filtering device, wherein each of the filtering device and the waste shield is configured to be oriented at a non-horizontal angle and wherein the waste shield is configured to direct small industrial products falling through the filtering device toward a waste pile, (ii) belt positioned at or adjacent to a proximal edge of the filtering device, (iii) a first pipe extending along a length of the loading belt, (iv) a first spray nozzle coupled to a distal end of the first pipe, wherein the first spray nozzle is configured to spray a deicing fluid onto the small industrial products directed toward the waste pile by the waste shield, (v) a second pipe in fluid communication with the first pipe, and (vi) a second spray nozzle coupled to the second pipe, wherein the second spray nozzle is configured to spray the deicing fluid onto industrial products carried by the loading belt; and
contacting the plurality of screening elements with the material.
7 . The method of claim 6 , further comprising angling the plurality of screening elements perpendicular to the cross support and/or at an angle of 30-80 degrees relative to a direction of gravity.
8 . The method of claim 6 , further comprising sliding the material over the plurality of screening elements such that a portion of the material falls in between individual screening elements.
