Abstract

Claims (22)

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.
