Embodiment Construction

[0048] figure 1 A separator 2 is shown comprising a tray assembly 4 arranged within a processing vessel 6 . The tray assembly 4 includes a plurality of nested tray units 14 . exist figure 1 Five tray units 14 are shown, but it should be understood that the tray assembly may include more or fewer tray units 14 . Nested tray units 14 define a separator axis 16, as figure 2 and 3 As shown, the separator axis is upright and preferably substantially vertical. The tray units 14 are spaced apart from each other along the axis 16 . The processing vessel 6 is provided with an inlet chute 8 and a fluid outlet 12 .

[0049] Each tray unit 14 includes a generally frusto-conical tray 18 having a circular aperture 20 at the apex of the tray 18 . The axis of the conical shape of the tray 18 is aligned with the separator axis 16 . The trays 18 are grouped in a downward direction. A cylindrical rim 24 extends upwardly from the outer periphery of the tray 18 , and an annular lip 26 ex...

Abstract

There is described a tray unit for a wastewater treatment device. The tray unit has a substantially frusto-conical profile defining an axis and a central aperture. The tray unit comprises a pluralityof distinct tray sections arranged around the axis. Each tray section comprises a portion of the substantially frusto-conical profile of the tray unit and is connectable to one or more of the other tray sections so as to form the tray unit. There is also described a method of assembling a tray assembly for a wastewater treatment device. The method comprises the steps of: providing a plurality of tray units, the tray units each having a substantially frusto-conical profile and a central aperture and comprising a plurality of connecting lugs each defining a hole; attaching a first one of the tray units to a plurality of support members by inserting the support members through the hole of the connecting lug of the first tray unit and securing the first tray unit to the support member; and attaching a second one of the tray units to the plurality of support members by inserting the support members through the hole of the connecting lug of the second tray unit and securing the second tray unit to the support member to form an assembly of tray units.

Description

technical field [0001] The present invention relates to a tray unit for a waste water treatment device and an assembly method for a tray assembly for a waste water treatment device. Background technique [0002] Wastewater treatment plants are known in which a plurality of trays are provided to remove grit from the waste water stream. Gravel particles entrained in the wastewater stream settle on the sloped inner surface of each tray, and these particles are then attracted toward and through openings in the trays into a collection area. The degritted wastewater flows through the trays for further treatment. [0003] Such pallets are expensive to manufacture and difficult to transport. In addition, trays must meet specific requirements regarding shape and size to ensure optimum flow conditions within wastewater treatment plants. Therefore, it is desirable to provide a tray unit for a waste water treatment plant and a method of assembling a tray assembly for a waste water tr...
