Abstract
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.
Claims8
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.
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.
