Description of the embodiments

The present disclosure relates to filtering apparatus and methods and, in particular, to the use of improved sieve baskets for use in methods and systems for sucking up metals from metal-containing ores. Embodiments of the present disclosure may be used, inter alia, with carbon-in-pulp (CIP), leaching carbon (CIL) and leaching resin (RIL) systems, among others. The CIL and CIP systems are, for example, two countercurrent methods for the adsorption of leached gold from a sludge stream on activated carbon. In such CIL and CIP processes, a series of adsorption tanks are placed in a series. The sludge flows continuously from the first tank in this series to the last tank. At the same time, the carbon is pumped countercurrently from the last tank in the series to the first tank. CIP (CIL) and CIP processes differ in that gold is leached before carbon adsorption. For example, in a CIL operation, carbon is added to the leaching tanks, and the leaching reaction and adsorption take place simultaneously. In contrast, in the CIP process, most leachate gold is leached before the first adsorption stage.

A description of a general process for recovering gold from a gold ore using a combined cyanide and adsorption treatment can be found in US Pat. No. 4,188,208. Although embodiments of the present disclosure are generally discussed. With reference to gold or carbon, embodiments of this disclosure may be applied equally to processes for the recovery of silver, iron, nickel and other metals from the appropriate ore. The recovery of any metal from a mine ore falls within the scope of the present disclosure.

A description of existing metal sieve baskets and methods of using them in the CIP processes described above can be found in U.S. Patent No. 5,238,117. The process described in U.S. Pat.

5,238,117 has become generally known in the art as NKM vertically washed inter-stage separation processes, and the sieve baskets used therein have become generally known in the art as NKM sieve baskets. In general, such NKM sieve baskets include a metal support frame provided with a wide profiled sieve, wrapped around a side wall thereof. The profiled wire sieve is used to filter materials from a metal-rich sludge. The sieve basket is attached to an NKM separator and a lower portion of this NKM separator, including the attached NKM sieve basket, is immersed in a tank containing carbon-in-pulp material. The rotors on the NKM separator cause the slurry in the tank to flow through the profiled wire sieve and into the NKM sieve. However, the profiled wire screen has a very low open separation area, which leads to inefficient separation. The low open separation area also leads to clogging. clogging, in turn, forces increased sludge volumes to flow through unclogged areas of the profiled wire sieve, which increases the sieve wear rate. In addition, the individual wires that form the profiled wire sieves tend to deteriorate or break over time due to forces encountered during the separation processes, such as washing the internal and external propulsion blades.

In exemplary embodiments of the present disclosure, an improved sieve basket device for separating the material is provided. The device comprises a support frame having a substantially closed bottom and an open top, and a substantially cylindrical side wall support portion extending between the bottom and top of the support frame. The support frame can be metallic, such as stainless steel. A side wall of the polyurethane screen extends around and is supported by the supporting portion of the side wall. The side wall of the polyurethane screen comprises a polyurethane screen with a high open surface. In certain embodiments, the side wall of the polyurethane screen substantially comprises the supporting portion of the side wall between the closed bottom and the open top, so as to ensure a maximum separation area. The side wall of the polyurethane screen can be fixed on an outer periphery of the supporting part of the side wall.

The side wall of the polyurethane screen can be formed of a plurality of individual polyurethane screen elements. These individual polyurethane sieve elements can be aligned adjacent to each other to ensure a generally continuous separation zone on the side wall of the sieve. In one example, the plurality of individual polyurethane sieve elements may include eight individual sieve elements

made of polyurethane. In such embodiments, these eight individual polyurethane sieve elements may be arranged so that four of the sieve elements are on the lower half of the support frame and four of the sieve elements are on the upper half of the support frame. .

In certain embodiments, the substantially closed bottom may be provided with a centralized opening that allows the reception of the drive shaft of an NKM apparatus.

The high open surface polyurethane sieve element, in certain embodiments, comprises a flexible cast polyurethane body; some screen openings provided in the body; a set of substantially parallel flexible first elements defining opposite opposite faces of the screen openings; a set of substantially parallel secondary flexible elements, which define opposite secondary faces of the sieve openings, in which the secondary elements are substantially perpendicular to the secondary elements; a set of tertiary elements, substantially parallel, with a plurality of prime elements between them; a set of quadruple elements, substantially parallel, having a plurality of secondary elements between them; portions of the lateral margin substantially parallel to opposite sides of the body, between which the tertiary elements extend; and a first end portion and a second end portion substantially parallel to the opposite ends of the body, between which extend its quadruple elements, in which the end portions are substantially perpendicular to the edge portions. The sieve openings in the molded polyurethane flexible body of the polyurethane screen element may be from about 0.044 mm to about 4,000 mm between some inner surfaces of the first elements and from about 0.044 mm to about 60,000 mm between some inner surfaces of the elements secondary.

The polyurethane sieve element may also include reinforcing elements fully cast in at least one of the first elements and the tertiary elements and at least one of the secondary and quadruple elements. In some embodiments, the reinforcement elements formed entirely in the first elements may have a substantially uniform thickness, having an amplitude between about 0.006 inches and about 0.015 inches. Fully cast reinforcements with secondary elements can be substantially uniform in thickness, with an amplitude between about 0.015 inches and about 0.040 inches. The reinforcing elements can be incorporated, for example, into rods which can be cast entirely with the elements. Reinforcing elements can also be incorporated, for example, into

RO 135261 A2 dl · Aramid fibers representing at least one twisted and woven multifibre, the fibers having a linear density of about 55 denier to about 2840 denier.

The side edge portions of the polyurethane sieve element can be configured for use when attaching the sieve element to the support frame. A plurality of enlarged polyurethane ribs may be formed entirely on an outer surface of the polyurethane sieve body, with the ribs arranged substantially vertically relative to the supporting portion of the side wall. Each of the plurality of ribs can extend substantially from the top to the bottom of the polyurethane sieve element.

In other embodiments of the present disclosure, a basket-like cage may be provided that includes a tubular or substantially cylindrical network frame provided with multiple openings. Multiple openings in the network frame can be arranged in a square network, and each (or, in some cases, at least some) of the multiple openings can be square in shape. In an exemplary embodiment, the multiple openings may include 264 square openings. A subset of multiple openings can be defined by longitudinal elements and transverse elements. A second subset of multiple openings may be defined by longitudinal elements and cross-sections of a first annular section of the network frame, and similarly a third subset of multiple openings may be defined by longitudinal elements and cross-sections of a two annular sections of the network frame.

The basket cage may have flanges at the top and bottom of the cage. The top flange and openings may allow or otherwise facilitate the mounting of a plate or other type of cover on the flange. In addition or in other embodiments, the flange and openings may allow or otherwise facilitate the mounting of the chimney cage in a sieve separator (eg an NKM vertical washer interlocking device).

The basket cage can be used in a process of separating a specific material in the form of sludge particles or another type of fluid source. To this end, in one embodiment, the separating cartridge assemblies may be mounted on the basket cage, where the separating cartridge assemblies may allow or otherwise facilitate the separation of a specific particulate matter from the sludge. Each of the separating cartridge assemblies may be mounted or otherwise fixed to a respective group of network elements which define, at least in part, a respective opening of the network frame. For openings in a row around the longitudinal axis of the network frame, a group of network elements supporting a first separation cartridge assembly may have a common network element with another group of network elements supporting a second set of cartridge assemblies of> »1 network.

In some embodiments, each of the multiple separator cartridge assemblies mounted or attached to the network frame includes a separator assembly and a housing (or other type of container) configured to receive and retain the sieve assembly. . In some embodiments, the housing may be made of a single injection molded part, formed entirely by injection molding of a polyurethane, a heat-resistant polymer or other types of polymer. Examples of embodiments of the injection molded workpiece and the injection molded workpiece forming process are discussed in more detail in the disclosures of U.S. Pat. 13 / 800,826, U.S. Pat. U.S. Patent No. 9,409,209 to U.S. Pat. 9,884,344, U.S. Patent Application No. 15 / 851,009, US patent application no. 15 / 965,195 and in the cross-references included therein, which are incorporated herein by reference in their entirety.

The sieve assembly has, in some embodiments, three individual sieve units. The housing includes a first opening configured to receive and / or secure the screen assembly to the housing, and a second opening that allows a screen assembly separating surface to be exposed to the outside of the network frame. The housing also includes ridges extending from a first edge of the housing, near the first opening, to a second, opposite edge of the housing. The respective ridges and portions of the housing form recesses which allow or otherwise facilitate the mounting (for example, clamping or snapping) of the housing on the network frame. »

The network frame, in whole or in part, of the sieve basket may be covered with separating cartridge assemblies during a separation process. As such, in an exemplary embodiment, the separating cartridge assemblies 264 may be mounted on said square openings 264 in the network frame. J

Furthermore, the case may include an attachment frame section and a support frame section. The support frame section may receive and / or retain the sieve assembly consisting of sieve units. The attachment frame section may include a set of ridges which form respective recesses, which in turn allow or otherwise facilitate the attachment (e.g., by snapping, clamping, or otherwise coupling) of the separating cartridge assembly to a network framework.

The sieve cartridges according to the present disclosure may have any shape suitable for attaching to a network frame of a basket cage. For example, and without limitation, sieve cartridges can be square, rectangular, oval, or any other shape. Although some exemplary embodiments may provide sieve cartridges that are configured to substantially match the network openings of the network frame (i.e., a square sieve cartridge on a network frame with square network openings), the type cartridges sieves of different shapes can be attached to network openings of different shapes. Similarly, the net frame of the basket cage may be of any shape suitable for separation.

Sieve elements and sieve cartridges according to the embodiments discussed herein resist wear, abrasion, bending and chemicals better than metal and thus tend to last longer than profiled wire frames in CIL processes. The sieve elements, as discussed here, also allow the formation of significantly smaller sieve openings than conventional profiled wire frames, which in turn improves the separation efficiency. The use of sieve elements, as described here, provides significantly larger separation areas and significantly reduces clogging compared to conventional profiled wire sieve baskets. In use, sieve elements and sieve cartridges, as described herein, also allow a substantially consistent distance between the external propulsion blades of the separator and the separator cartridge assembly, thereby reducing clogging and prolonging life. life of the sieve elements.

With reference to the embodiment shown in FIG. 1 to 5, the screen basket 1 of the present disclosure comprises a basket frame structure 510 having a high open surface polyurethane screen 600 attached thereto.

As shown in FIG. 1, the basket frame 510 generally has a cylindrical configuration, although other shapes may be used. The basket frame 510 can preferably be made of stainless steel, although other materials may be used.

As shown in FIG. 3, the basket frame support 510 may consist of a plurality of vertical supports 530 and a plurality of horizontal supports 550. The embodiment shown in FIG. 3 includes four primary support elements 531 spaced along a periphery of the frame 510, together with a plurality of secondary support elements 542 arranged at a distance between the primary support elements 531. together, the primary and secondary support elements 531, 542 joins the upper and lower ends 511, 515 of the frame 510 in a spaced arrangement. The horizontal support members 550 may be provided by a plurality of annular rings or curved sections which are joined together to form a plurality of annular rings in a spaced arrangement over the entire basket frame 510.

As shown in FIG. 3, each of the vertical support elements 531 may include an inner portion of the pillar 532. The inner portion of the pillar 532 may in turn include some openings 534 provided therein. The horizontal support elements 550 pass through the openings 534, thus maintaining the horizontal support elements 550 in a stacked and spaced arrangement.

As shown in the top view of FIG. 2, the upper end 511 of the frame 510 is provided with an opening to allow use when receiving and processing the materials in the sieve basket 1. The lower end 515 of the frame 510 is provided with a bottom 516 substantially solid or closed, to retain materials in the sieve basket 1 during processing. The substantially closed bottom 516 may be provided with a central opening 517 for use in machining shaft operating arrangements, as discussed in more detail below.

Some embodiments of the disclosure may include a wide open polyurethane screen 600 attached to a periphery of the frame 510, thereby forming a screen basket 1 having an open top, a substantially solid bottom 516, or closed and a 601 polyurethane sieve side wall.

The polyurethane sieve 600 may be provided in the form of separate, smaller elements of the sieve 10, as a result of potential size constraints in the process of pouring the polyurethane sieve 600. For example, as in the embodiment shown in FIG. 1, the polyurethane screen 600 may have a plurality of separate screen elements 10. Each screen element 10 is attached to the vertical support of the frame 510.

FIG. 4 to 6 show the characteristics of an exemplary embodiment of a sieve element 10 configured for use in forming the side wall of the polyurethane sieve 601 of a sieve basket 1. FIG. 4 to 5 show the outer and inner sides of an embodiment of the sieve element 10, respectively, while FIG. 6 shows a side view of an alternative embodiment of the sieve element 10. The sieve element 10 may comprise polyurethane sieves described in more detail in the following patents and patent publications, which have a common applicant with that of the present disclosure and are included by reference herein: U.S. Pat. 8,584,866; U.S. Pat. 9,010,539; U.S. Pat. 9,375,756; U.S. Pat. 9,403,192; U.S. Patent Application Publication no. 2015 / 0197827A1; and U.S. Patent Application Publication No. 2016 / 0303611A1.

As shown in FIG. from 4 to 7, an embodiment of the present disclosure may provide a sieve element 10 with a molded polyurethane body 12 having non-perforated side edge portions 14, 16. The side edge portions 14, 16 may each have a built-in side burr portion 29 for use in sealing adjacent sieve elements 10 and securing the sieve elements 10 to the basket frame 510, as shown in FIG. 7. Each side edge portion 14,16 may include a molded structural member for use in reinforcing the side burr portion 29. The side edge portions 14, 16 may also be formed without molded structural members or may include other structural elements. The burr side portions 29 may be designed in any shape suitable for attachment to a basket frame 510. In an exemplary embodiment, the burr side portions 29 may include a formed member, e.g., a metal member that is bent to a desired shape, for example, a U-shaped element, an L-shaped element, a C-shaped element or the like. The formed element may be attached to the polyurethane body by heating, pressing, mechanical, chemical, casting and / or any other suitable method or arrangement.

The body 12 of the sieve element 10 also includes a lower edge portion 18 and an upper edge portion 20, which, in combination with some side edge portions 14, 16, define an outer edge of the sieve element 10. sieve 10. In certain embodiments, a side burr portion 29 may extend the entire length between the upper edge portion 20 and the lower edge portion 18.

The body 12 further includes an outer surface 22 and an inner surface 24. FIG. 4 illustrates an outer surface 22 of the body 12 when the sieve member 10 is fixed to the basket frame 510, as shown, for example, in FIG. 1, and FIG. 5 illustrates an inner surface 24 of the body 12 when the sieve member is fixed to the basket frame 510, as shown, for example, in FIG. 1. Body 12 includes first elements 101 and secondary elements 102 which form sieve openings 26, as shown in detail in FIG. 8 and FIG. 8A. The first elements 101 and the secondary elements 102 may, in some embodiments, be configured to include reinforcing elements 50, as discussed in more detail below. As shown in the side view of FIG. 6, the screen member 10 may further include vertical ribs 28 provided on the outer surface 22 of the screen member 10. The screen member 10 may not, however, include vertical ribs 28 in certain embodiments of the present disclosure.

Body 12 may further include tertiary elements 203 and quadruple elements 204. Tertiary elements 203 and quadruple elements 204, and vertical ribs 28, if present, may also include reinforcing elements 50, discussed in more detail below. down. However, tertiary elements 203, quadruple elements 204 and vertical ribs 28 may not include reinforcing elements 50 in certain embodiments of the present disclosure. The tertiary elements 203 and the quadruple elements 204 are generally configured to support the screen openings 26 formed by the first elements and the secondary elements 101, 102.

FIG. 8 shows a portion of an embodiment of the sieve element 10, with FIG. 8A illustrates an enlarged view of a portion of FIG. 8. As shown in the detail image in FIG. 8A, the first elements and the secondary elements 101, 102 form a first fully cast network structure 100 which defines sieve openings 26. The tertiary and quadruple elements 203, 204 may form a second fully cast network structure 200 and some quintuple elements respectively, and 305 and 306, respectively, may in turn form a third fully cast network structure 300.

The reinforcing elements 50 can be incorporated into desired elements of the sieve element 10. The reinforcing elements 50 ensure the stability of the sieve element 10 by preventing deformation and / or sandblasting of the side edges 14, 16. In an exemplary embodiment , the reinforcing elements 50 can be integrated (such as by integral casting) into corresponding elements. The reinforcing elements 50 can be made of plastic, metal, polymer or any other suitable material with the necessary structural properties. For example, the reinforcing elements 50 may be configured in the form of rods which are cast entirely with the sieve elements. The reinforcing elements 50 can also be configured as aramid fibers which are represented by at least one of a twisted multifir and a woven multifir, so that the fibers act as wicks to absorb the polyurethane cast around it, thus providing a bond strong with it. The twisted or woven multifiber fibers may have a linear density of about 55 denier to about 2840 denier and preferably may be about 1500 denier. When an aramid fiber is used in the embodiments of the present disclosure, it may be a set of commercially available aramid fibers under the brand name KEVLAR® from DuPont Company. Reinforcing elements 50 may also be at least one of the commercially available aramid fibers under the trade names TWARON, SULFRON, TEIJINCONEX and TECHNORA of Teijin. The flexibility of the aramid fibers ensures a flexible reinforcement system for the cast polyurethane, which is able to return to its original cast shape after the necessary bending and bending, which take place during handling and installation. In certain embodiments, the reinforcing members 50 may be tensioned before the polyurethane is poured around them.

Referring again to the embodiment shown in FIG. 4 to 5, and the detail view shown in FIG. 8, the network structures 200 and 300 include fully cast bidirectional elements, which form support grids within the elements. Due to the properties of the reinforcing elements 50 and the configuration of the two-way network structure, the elements may be relatively small in size and thus provide an enlarged open separation area. The grid structures provide a sieve resistance and support for the openings 26 during vibratory loading and significantly increase the open separation area.

As shown in the detailed view of FIG. 8A, the first elements 101 can extend transversely between the side edge portions 14, 16, in a substantially parallel manner to each other. The secondary elements 102 may extend transversely between the lower edge portion 18 and the upper edge portion 20, in a manner substantially parallel to each other and substantially perpendicular to the first elements 101. In certain embodiments, the secondary elements 102 may have a thicker thickness. greater than the first elements 101 to provide additional structural support to the sieve openings 26.

As mentioned above, and as shown in the exploded isometric view of FIG. 12, the first elements 101 and / or the secondary elements 102 may include reinforcing elements 50 and may or may not be supported by additional supporting elements or support network structures. For example, as shown in FIG. 9, which describes a fragmentary cross-sectional view of the body 12 of the sieve element 10, the body 12 includes some first elements and secondary elements 101, 102 with bidirectional reinforcing elements 50 cast entirely with it. The fully molded reinforcing elements 50 with the first elements 101 have a thickness of between about 0.006 rings and about 0.015 inches. Fully cast reinforcement elements 50 with secondary elements 102 (not shown) have a thickness of between about 0.015 inches and about 0.040 inches. Such configurations can be beneficial

RO 135261 A2, in case of separation applications requiring site with larger screen openings.

Embodiments of the present disclosure may incorporate reinforcing elements 50 in any of the first, secondary, tertiary and quadruple elements 101, 102, 203, 204, as well as in the ribs 28, and may be incorporated in their entirety or in their entirety. a portion of the first, secondary, tertiary and quadruple elements 101, 102, 203, 204 and the rib elements 28.

As shown in FIG. 8 and in detail in FIG. 8A, the sieve openings 26 may be elongated, with a larger length along the sides and between their ends than the width dimensions. The sieve openings 26 can be about 0.044 mm to about 4.0 mm wide, the width being the size between the inner surfaces of the first adjacent elements 101. The sieve openings 26 can be about 0.44 mm to about 60 mm long, the length being the size between the inner surfaces of the adjacent secondary elements 102. In addition, the sieve openings 26 may take a variety of different shapes. For example, the sieve openings 26 may have a rectangular shape, or a square shape, or an oval shape, or any other shape that may be formed of the first elements and the secondary elements 101, 102. The general dimensions of the sieve element 10 may be be approximately 1.2 meters by 1.6 meters or can have any other desired size. It is to be understood that all the dimensions presented here are by way of example only and not by way of limitation.

Referring briefly to FIG. 10 and FIG. 11, the sieve openings 26 may deviate downwards between the outer surface 22 and the inner surface 24, the first elements 101 being substantially in the form of inverted trapezoids. This general trapezoidal shape of the first elements 101 prevents clogging in the sieve element 10 and as a whole in the polyurethane screen 600. The first elements 101 may include reinforcing elements 50 cast entirely with them, as shown in FIG. 10, or optionally may not include reinforcing elements 50 cast entirely therewith, as shown in FIG. 11.

As illustrated in detail in FIG. 8A, tertiary and quadruple elements 203, 204 may be thicker than the first elements and secondary elements 101, 102. The increased thickness of the tertiary and quadruple elements 203, 204 may provide additional structural support to the first elements and secondary elements 101, 102. As shown in the exemplary embodiment of

FIG. 8 and 8A, the tertiary elements 203 may extend transversely between the side edge portions 14, 16 in a manner substantially parallel to each other and may have some first multiple elements 101 present between them. The quadruple elements 204 may extend transversely between the lower edge portion 18 and the upper edge portion 20 in a substantially parallel manner and may have multiple secondary elements 102 present between them. The reinforcing elements 50 can be modeled entirely with the tertiary and quadruple elements 203, 204. The tertiary and quadruple elements 203, 204 can be configured to have a minimum thickness by including reinforcing elements 50, while maintaining the necessary structural support for the screen openings 26 formed by the first elements and the secondary elements 101, 102 during the vibratory separation applications. The two-way support system provided by the tertiary and quadruple elements 203, 204 and the additional support of the reinforcing elements 50 integrated therein, where included, greatly reduces the thickness of the support elements and ensures an increase in the open separation area and overall efficiency. of the site.

The body 12 may further include a plurality of vertical ribs 28. in the embodiment shown in FIG. from 4 to 6, a series of nine ribs 28 may be provided. The ribs 28 may have a thickness greater than that of the tertiary and quadruple elements 203, 204 and may have a portion extending beyond the inner surface 24 of body 12. As shown in FIG. 2, the ribs 28 may also be provided to extend beyond the outer surface 522 of the body 12 and thus provide a vertical support along the outer side wall of the sieve 601. The greater thickness and positioning of the ribs 28 ensures additional structural support for the first elements and the secondary elements 101,102.

The ribs 28 may extend transversely between the lower edge portion 18 and the upper edge portion 20 in a substantially parallel manner to each other and may have between them multiple quadruple elements 204.

RO 135261 A2 l

Different configurations of the reinforcing elements 50 may be provided in the support rib elements 28 to add stability to the sieve elements 10. The reinforcing elements 50 provided in the supporting rib elements 28 may be represented by an aramid fiber ( or individual filaments thereof), a naturally occurring fiber or other material with relatively high tensile strength, with relatively small cross-sections. 1

Each element of the sieve element 10 capable of including such reinforcing elements 50 may include zero, one or more reinforcing elements 50, and the reinforcing elements 50 used for them may be of different sizes and materials. The reinforcing elements 50 can be placed in the lower halves of the elements, so that they are not exposed relatively early during the life of the sieve element 10, as the upper surface of the sieve can wear out.

The inclusion of the reinforcing elements 50, as well as the supporting frame of the bi-directional supporting elements, allows the first elements 101, as well as the secondary elements 102, to be relatively thin, creating larger screen openings. The embodiments described herein have relatively high tensile strengths with relatively small cross-sectional areas. The realization of the supporting elements and the first thin elements 101 results in the fact that the sieve element 10 and the sieve 600 as a whole have a higher percentage of open surface, which, in turn, increases the capacity of the system. The open separation zones, according to the embodiments described herein, may vary, for example, from about 40 percent to about 46 percent of the sieve.

According to an exemplary embodiment of the present disclosure, a vibrating screen 10 includes a flexible cast polyurethane body 12 having substantially parallel side edge portions 14, 16 at opposite ends of the body 12, and a edge portion bottom 18 substantially perpendicular to the side edge portions 14, 16, and a top edge portion 20 substantially perpendicular to the side edge portions 14, 16 and opposite the bottom edge portion 18. The polyurethane body 12 further includes a outer surface 22 and inner surface 24. The first elements and the secondary elements 101, 102 are provided to form some separation openings 26. The first elements 101 extend between the side edge portions 14, 16 and the secondary elements 102 extend between the portions lower and upper edge 18, 20. Body 12 may also include tertiary and quadruple elements 203, 20 4, with the tertiary and quadruple elements 203, 204 having a greater thickness than the first elements and the secondary elements 101, 102. The tertiary elements 203 extend substantially (// parallel to each other and extend transversely between the portions of side edge 14, 16 and have several first elements 101 present between them. The quadruple elements 204 extend substantially parallel to each other and extend transversely between the lower and upper edge portions 18, 20 and have several secondary elements 102 present between them. The reinforcing elements 50 can be cast entirely with tertiary and / or quadruple elements 203, 204 and, in addition, the reinforcing elements or reinforcing rods can be cast entirely with the quadruple elements 204. The body 12 also includes ribs 28. The ribs 28 may be substantially parallel to each other and extend transversely between the side edge portions 14, 16. The ribs 28 may also be substantially parallel to each other and extend transversely between the lower and upper edge portions 18, 20. The ribs 28 they have a thickness greater than that of the tertiary and quadruple elements 203, 204, and may include reinforcing elements 50 cast entirely with them. The body 12 may additionally have quintuple and sextuple elements 305, 306. The quintuple elements 305 extend substantially parallel to each other and extend transversely between the side edge portions 14, 16 and have several tertiary elements 203 present between them. The sextuple elements 306 extend substantially parallel to each other and extend transversely between the lower and upper edge portions 18, 20 and have several quadruple elements 204 present between them. The reinforcing elements 50 can be cast in their entirety with the quintuple and / or sextuple elements 305, 306 and, in addition, the reinforcing elements or reinforcing rods can be cast in their entirety with the sextuple elements 306.

The sieve elements according to this embodiment may have open separation areas greater than 40% and mesh sizes between about 0.375 mesh and about 400 mesh. For example, the tested sieves with the above configurations included a 43 mesh sieve, a 140 mesh sieve and a 210 mesh sieve. Each of these sites had open separation areas, from about 40 percent to about 46 percent. Such large separation areas for such relatively fine mesh sizes are obtained by the relatively strong and thin mesh frame created by the tertiary, quadruple, quintuple and sextuple elements 203, 204, 305, 306 and the reinforcement elements cast entirely with them. .

In the embodiments and examples mentioned above, the size of each network unit formed by the intersection of the tertiary and quadruple elements 203, 204 is about 1 inch by 1 inch. In general, network units may be larger for sites with larger sieve openings and network units may be smaller for sites with smaller sieve openings. This principle may be generally applicable to each exemplary embodiment discussed herein. Network units may also have a generally rectangular shape or any other shape suitable for supporting screen openings.

The use of polyurethane sieve elements 10 as described herein to form a sieve side wall 601 on a chimney frame has significant advantages over conventional profiled wire sieves. Polyurethane sieve elements 10, as described here, are more resistant to wear, abrasion, bending and chemicals than metal and thus tend to last longer than profiled wire frames in CIL processes. Polyurethane also allows the formation of significantly smaller sieve openings than conventional profiled wire frames, which in turn improves the separation efficiency. The use of polyurethane sieve elements 10, as described herein, provides significantly larger separation areas and significantly reduces clogging compared to conventional profiled wire sieve baskets.

In operation, the sieve basket 1 described herein can be used with known CIP and CIL devices and methods, such as those described in U.S. Pat. 5,238,117. For example, as shown in FIG. 13-14, the sieve basket 1 is attached under a volute-type portion of an NKM vertical wash interleaver. An NKM drive shaft passes through the top, bottom of the sieve basket 1 and through the central opening at the closed bottom of the sieve basket 1. A gearbox and motor are positioned above the volute for feed the drive shaft. A wash interface is located above the polyurethane sieve and the scroll interface to receive the sludge discharge flow.

With the sieve basket 1 attached to the NKM apparatus, the lower portion of the NKM device, including the sieve basket 1, is inserted and suspended over a large adsorption tank containing slurry suspension to be processed. The level of sludge in the tank is higher than the level of the fluid in the sieve basket 1. This arrangement causes the sludge to flow naturally through the sieve of the sieve basket 1, in an effort to equalize the fluid levels in the sludge tank and sieve basket 1. The blades on the outside of the NKM unit rotate inside the tank, around an outer periphery of the side wall of the sieve basket 1. The outer blades also help to prevent particulate clogging on the outside of the sieve. polyurethane, such as carbon and sludge. The impulse and the sweeping action reduce the possibility of carbon and material of similar dimensions to clog the sieve openings. The rotor blades located inside the sieve, such as on the drive shaft, are used to keep the particles in suspension and to drive the sludge upwards towards the volute and the washing device.

During the process, the sludge flows upwards through the inside of the sieve basket 1. The carbon is retained in the sieve. The sludge exists through the washing interface located above the polyurethane sieve and the volute interface.

In these processes, it can be seen that the continuous rotation of the inner and outer blades in the vicinity of the polyurethane sieve, together with the flow of large volumes of sludge through the openings of the polyurethane sieve, subject the sieve to substantial wear and cracking. The polyurethane sieves and the arrangement of the sieve basket described here are designed to withstand significant wear and cracking and to substantially outperform the existing wire sieve baskets from the CIP and CIL processes.

Although the sieve basket 1 has been described for use in a CIP or CIL process, the relatively small openings and the relatively large separation area of the polyurethane sieve elements 10 described here allow the sieve basket 1 to be used for other purposes, such as water filtration and desalination.

FIG. 15 illustrates a perspective view of an example of a basket cage 1500 in accordance with a further embodiment of the disclosure. The basket cage 1500 includes a grid frame 1510 which is tubular (or has a substantially cylindrical symmetry) with respect to a longitudinal axis and has multiple openings 1513. As such, the grid frame 1510 has a height and a diameter. As shown in the illustration, the height can be between 23 inches (about 58 cm) and about 122 inches (about 310 cm) wide. According to another illustration, the diameter may have an amplitude between about 10 in (about 25.4 cm) and about 73 in (about 185.4 cm). In an exemplary embodiment, the height has an amplitude of about 80 in (about 203.2 cm) and the diameter has an amplitude of about 50 in (about 127 cm). It is noted that the disclosure is not limited to such illustrative sizes of height and / or diameter, and other dimensions of the 1510 network frame may be considered. In addition, the network frame 1510 is not limited to tubular or cylindrical symmetry, but can be configured in any configuration suitable for separation and, in particular, for carbon sequestration, as discussed here.

In other embodiments, the perforated sheet may be made of a rigid plastic, and the opposite edges may be joined by laser welding and / or bonding with a suitable adhesive. The multiple openings 1513 of the network frame 1510 may be arranged in a square network, and each (or, in some embodiments, at least some) of the multiple openings 1513 may be square in shape. Multiple openings 1513 may have shapes other than a square shape, such as a rectangular shape, an oval shape, a circular shape, and so on. Moreover, it is not necessary for the multiple openings 1513 to have a consistent shape over the entire network frame 1510. For example, some embodiments may have alternating rectangular openings of different sizes to form the general network frame 1510. In an exemplary embodiment, the multiple openings 1513 may include 264 square openings. A subset of multiple openings can be defined by longitudinal elements 1511 and transverse elements 1512. The openings in such a subset may be called interior openings.

A flange 1520 may be fixed or otherwise attached to one end of the first annular section 1512a. The flange 1520 may include several first openings 1525. The flange 1520 and the first openings 1525 may allow or otherwise facilitate the mounting of a plate or other type of cover on the flange 1520. In addition or in other embodiments, the flange 1520 and the first openings 1525 may allow or otherwise facilitate the mounting of the basket basket 1500 in a sieve separator (for example, an NKM vertical washer interlocking apparatus, as shown in FIG. 13 and FIG. 14). In addition, a second flange 1530 may be fixed or otherwise attached to the second annular section 1512b. The second flange 1530 may include several secondary openings 1535. The flange 1530 and the secondary openings 1535 may allow or otherwise facilitate the mounting of the basket basket 1500 in a sieve separator (for example, an interlocking apparatus with vertical washing NKM, as shown in FIG. 13 and FIG. 14) and / or fixing an external washing assembly of the sieve separator (not shown).

As illustrated in FIG. 15, the basket cage 1500 may also include an opening near the second end of the network frame 1510, near the second flange 1530. A pipe member 1540 may be assembled in the vicinity of the opening. The opening and the pipe element 1540 may form an outlet which may allow or otherwise facilitate the leakage of sludge from inside the 1500 basket cage when it is to be drained. and

Similar to other sieve baskets of this disclosure, the 1500 basket cage, in combination with separating elements, can be used in a process of separating a material in the form of specific particles from sludge or other source. of fluid.

Other interior side walls are not visible in perspective in FIG. 19A. For example, as shown in the 1950 cross-sectional view of the 1810 housing shown in FIG. 19B, a 1960 side wall opposite the 1920 side wall and a 1980 side wall opposite the 1930 side wall are also included in the inner side walls of the 1854 support frame section.

The side wall 1920, in connection with the side walls 1930 and 1980, may define a first opening and the side wall opposite 1960, in connection with the side walls 1930 and 1980, may define a second opening. The second opening may have a larger cross-sectional area than the cross-sectional area of the first opening, to mitigate the undesired reduction of the separation area. The smaller cross section can provide greater mechanical stability for a screen assembly arranged in the 1810 housing. The first opening and the second opening may allow the flow of particulate material from the outside to the inside of a separator cartridge assembly. which includes the 1810 housing.

As shown in FIG. 22C, a sieve element includes some surface elements 84 which extend parallel to the end portions of the sieve element 2220 and form some separation openings 86. The surface elements 84 have a thickness T, which may vary depending on the application of separation and the configuration of the separation openings 86. In this example, the separation openings 86 are elongated slots having a length L and a width W, which can be varied for a chosen configuration. The thickness T of the surface elements 84 may be from about 43 pm to about 1000 pm (i.e. from 0.0017 inches to 0.0394 inches) depending on the desired open separation area, and the width W of the opening openings. separation 86.

In some embodiments, the multiple separation openings may have a substantially uniform length L, having an amplitude between 300 μm and 4000 μm (i.e., from 0.0118 inches to 0.1575 inches). In addition, the multiple separation openings may have a substantially uniform width W, having an amplitude between 35 pm and about 4000 pm (i.e. from 0.0014 inches to 0.1575 inches). As shown in the illustration, in some embodiments, the amplitude of the width W may be approximately equal to one of the values of 43 pm (i.e., 0.0017 inches), 74 pm (i.e., 0.0029 inches) 90 pm (i.e. , 0.0035 inches), 104 pm (i.e., 0.0041 inches), 125 pm (i.e., 0.0049 inches), 150 pm (i.e., 0.0059 inches), 180 pm (i.e., 0.0071 inches) 500 pm (i.e., 0.0197 inches), 700 pm (i.e., 0.0276 inches), or 1000 pm (i.e., 0.0394 inches)

Table 2. (below) illustrates examples of additional configurations of surface elements 84 and parting openings 86. In this example, surface elements 84 have a fixed thickness T = 0.014 inches. Separation openings 86 have a fixed length L = 0.076 inches and a variable width W. As expected, for a fixed number of sieve openings 86, the percentage open area decreases with the width W of each sieve opening 86. in this example, the percentage open area varies from a minimum of 6.2% open area for the smallest width W = 0.0017 inches to a maximum open area of 23.3% for the largest width W = 0 .0071 inches.

Table 3. (below) illustrates examples of additional configurations of surface elements 84 and partition openings 86. Table 3 illustrates the effect of reducing the length L of the partition openings 86 and reducing the width T of the surface elements 84 , so that the screen element 1860 may include several screen elements. In this example, the surface elements 84 have a fixed thickness T = 0.007 inches. Separation openings 86 have a fixed length L = 0.046 inches and a variable width W. The resulting percentage open area varies from a minimum open area of 10.1%, for the smallest width W = 0.0017 inches, to a maximum open area of 27.3% for the largest width W = 0.0071 inches. Thus, the maximum percentage of open area is increased from 23.3% to 27.3% by reducing the T from 0.014 inches to 0.007 inches and by reducing the L from 0.076 inches to 0.046 inches, as seen by comparing the results in Table 3 with those in Table 2. As mentioned above, the increase in the maximum percentage of open area occurs because, when the separation openings 86 and the surface characteristics are reduced in size, several separation openings may be included on the element. sieve 1860.

Table 4. (below) illustrates other examples of configurations of surface elements 84 and partition openings 86. Table 4 shows that the trend can be continued. In this example, the surface elements 84 have a fixed thickness T = 0.005 inches. Separation openings 86 have a fixed length L = 0.032 inches and a variable width W. The resulting percentage open area varies from a minimum open area of 12.1%, for the smallest width W = 0.0017 inches, to a maximum open area of 31.4% for the widest width W = 0.0071 inches. Thus, by reducing the value of T from 0.007 inches to 0.005 inches and by reducing the value of L from 0.046 inches to 0.032 inches, the maximum open percentage area is increased from 27.3% to 31.4%, as shown by comparing the results in Table 4 with those in Table 3.
