[Background technology]
[0003] Continuous belt screen assemblies are used in wastewater treatment to filter solid debris from the wastewater. Continuous belt screen assemblies have screen panels that move continuously through the wastewater to capture solid debris carried in the wastewater, and therefore need to be fixed within the continuous belt screen assembly while facilitating rotation.
[0004] Over time, these screen panels lose their filtering efficiency and require replacement. To do this, the continuous belt screen assembly must be taken out of service and the associated screen panel removed and replaced. It is advantageous to shut down the assembly for as short a time as possible.

DETAILED DESCRIPTION OF THE INVENTION
[0018] In the drawings, the reference numeral 10 generally designates a mounting mechanism 10 for mounting screen panels 12 to a continuous belt screen assembly 14 used to filter solid waste from a liquid (not shown) flowing through a flow path 19. As shown in Figures 1 and 2, the continuous belt screen assembly 14 includes a pair of spaced apart opposing endless belts 16, a shaft 18 extending parallel to and spaced apart between the pair of endless belts 16, and a plurality of screen panels 12 arranged between the belts 16 to form a screen 15.
[0019] The mounting mechanism 10 includes a first set of links 22 mountable in spaced-apart parallel relationship between the pair of belts 16, with each link 20 of the first set of links 22 defining a first recess 24 ( FIG. 3 a). The mounting mechanism 10 further includes a second set of links 28 mountable in spaced-apart parallel relationship between the pair of belts 16, with the second set of links 28 configured to be disposed between and aligned with the first set of links 22 ( FIG. 3 b). Each link 26 of the second set of links 28 defines a second recess 30, the second recess 30 facing away from the first recess 24 of the link 20 of the first set of links 22 such that, in use, the first recess 24 and the second recess 30 cooperate to substantially define a flow path 40 capable of receiving the screen panel 12 ( FIGS. 4-6 ).
[0020] As shown in Figure 3a, each link 20 of the first set of links 22 includes a lifter in the form of a hook 25 to assist in removing fibrous solid waste, such as hair and fibers, from a liquid. Each link 20 also defines a slot 21 extending through the hook 25. As shown in Figures 3a and 3b, each end 32, 33, 34, 35 of each link 20, 26 of the first set of links 22 and the second set of links 28 form a mounting structure defining an opening 36 through which the end 32, 33, 34, 35 of the link 20, 26 can be attached to one of the shafts 18, with the shaft 18 passing through the opening 36.
[0021] It will be understood by those skilled in the art that one or more links 20, 26 of the first set of links 22 and / or the second set of links 28 may be provided with hooks 25 or any other suitable lifters, and that the mounting structure may be formed in any suitable manner to enable the links 20, 26 to be attached to the shaft 18.
[0022] In some embodiments, when both the first set of links 22 and the second set of links 28 are attached to the shaft 18, the links 20 of the first set of links 22 are alternated with the links 26 of the second set of links 28 along the length 42 of the screen panel 12. The links 20 and links 26 are equally spaced from one another along the length 42 of the screen panel 12 to improve the stability of the screen panel 12 in the continuous belt screen assembly 14. It will be understood that in some embodiments, the links 20 and links 26 do not necessarily have to be alternated and may be grouped in other configurations.
[0023] 3a, 3b, and 6, each of the first and second recesses 24, 30 is substantially U-shaped to secure at least one side of the screen panel 12 to opposing longitudinal edges 48, 50. In this embodiment, the first and second recesses 24, 30 are formed to be disposed in opposite directions about the longitudinal axis 13 of the screen panel 12 to define the flow passage 40. Those skilled in the art will appreciate that the first and second recesses 24, 30 may be shaped in any suitable manner to be attachable in opposite directions to each other to define the flow passage 40.
[0024] In use, the shaft 18 of the continuous belt screen assembly 14 is inserted through the openings 36 in the first set of links 22 and the second set of links 28 so that the links 20 of the first set of links alternate with the links 26 of the second set of links 28 along the length 42 of the screen panel 12, with the first recesses 24 and the second recesses 30 opposing each other to form a flow channel 40. The screen panel 18 is positioned in the flow channel 40 so that the first set of links 22 are positioned on a side 44 of the screen panel 12 and the second set of links 28 are positioned on an opposite side 46 of the screen panel 12. The shaft 18 is connected to a pair of belt links 17 through openings 23 defined by the belt links. This process is repeated until a plurality of screen panels 12 are placed between the endless belt 16 and the endless belt 16 is completely formed, as shown in FIGS. 1 and 2.
[0025] Advantageously, because the screen panel 12 does not pass through the link sets 22, 28 but rather is supported within the flow channel 40 formed by the attachment of the link sets 22, 28 in accordance with the present disclosure, the first set of links 22 and the second set of links 28 do not require tight manufacturing tolerances. Furthermore, as best shown in FIG. 6 , the screen panel 12 can be secured within the flow channel 40 so that the axial plane of the screen panel 12, represented by dashed line 52, coincides with or intersects any portion of the shaft 18. This “axial plane” will be understood to be a plane that passes through the screen panel 12, is parallel to the longitudinal axis 13, and intersects the opposing longitudinal edges 48, 50. While FIG. 6 shows only link 20 for illustrative purposes, those skilled in the art will understand that a similar intersecting arrangement is provided by link 26. This intersecting arrangement can facilitate rotation of the screen panel 12 during operation when the continuous belt screen assembly 14 is in use.
[0026] It will be understood by those skilled in the art that the continuous belt screen assembly 14 may be provided with the mounting mechanism 10 included therein. It will also be understood that the mounting kit may be provided as a separate product including a first set of links and a second set of links configured for use in accordance with the present disclosure.
[0027] It will be apparent to those skilled in the art that numerous variations and / or modifications may be made to the above-described embodiments without departing from the broad general scope of the present disclosure, and the present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive.
