Embodiment Construction

[0058] Figure 1a A schematic side view showing the components of an existing basket 1 of a vibrating screen. The first and second sides 2, 4 of the basket 1 are shown when viewed from the front solids discharge end (not shown in this figure). The sides 2, 4 are supported in the usual manner on springs 5 ​​to allow an oscillating movement.

[0059] A drive mechanism 7 for imparting vibratory motion to the basket 1 is mounted to the side of the basket by bolts 6 . The drive mechanism 7 comprises a support end plate 8 with a pair of sleeves 10 forming a bridge from one side 2 of the basket to the other side 4 . Located within each bushing 10 is a shaft 12, 13 having an eccentric weight 14 disposed along its length. see Figure 1c A cross-section of the shaft and weight in . Figure 1a In , only one bushing 10 and its contents are visible, since in this example the shafts are at the same height. Figure 1b The mechanism 7 is shown when viewed from the direction X.

Abstract

A basket (1) for a shale shaker includes a front, solids discharge end (34) and a rear, feed end (36) spaced apart by opposed first and second sides (2,4). The first and second sides mount a drive mechanism (7). The drive mechanism includes a first eccentrically weighted shaft (12), mounted to the first side (2) of the basket for rotation about an axis transverse to the front to rear direction ofthe basket; a first shaft drive, coupled to the first shaft (12) and to a corresponding second eccentrically weighted shaft (12a), which is mounted to the second side of the basket (4) for rotation about an axis transverse to the front to rear direction of the basket. A drive module (48, 50) comprising two eccentrically weighted shafts mounted on bearings in a single housing (52) is also described.

Description

technical field [0001] The present invention relates to a vibrating screen for separating drilling cuttings from used drilling mud, for example during drilling operations, such as drilling oil wells. In particular, the present invention relates to a vibratory drive mechanism for achieving solid-liquid separation in the basket of a vibrating screen machine. Background technique [0002] A vibrating screen is a vibrating screening machine that includes a vibrating basket mounted to a base by elastic supports such as springs or rubber blocks. The basket is generally cuboid in shape. The basket has a solids discharge end commonly referred to as the front of the basket and a rear supply end commonly referred to as the rear or back of the basket. The two sides form a roughly cuboid shape. [0003] The screen panels within the basket are fitted with wire mesh usually tensioned to one or more screen surfaces of a suitable support frame. Where multiple screening decks are provide...
