An apparatus including a basket of a vibratory separator configured to impart motion to a screen, a wedge angle coupled to the basket, and a wedge configured to engage with the wedge angle to secure the screen within the basket, in which a portion of the wedge is magnetic.

A scalping insert includes a scalping surface having a plurality of scalping slots therethrough, and a vertical base portion. A shaker screen assembly includes a screen frame having at least one slot. A scalping insert is positioned in the at least one slot of the screen frame. Processing fluid using a shaker screen assembly includes providing a flow of fluid to the shaker screen assembly and flowing the fluid through both a scalping surface and a screen surface of a single shaker screen deck.

A filter device is configured to filter a liquid. The filter device includes a drum sized to receive the liquid and a plurality of filter panels coupled to the drum to define a plurality of discs. The liquid passes through at least a portion of one of the discs. Each filter panel includes a perimeter frame that defines a panel normal flow area and a filter media coupled to the perimeter frame. The filter media may be adapted to include a plurality of pleats.

A system for separating components from a slurry of drilling fluid and drill cuttings on a shaker screen having an upper side and a lower side within a shaker. The system also has a pressure differential generator to pull an effective volume of air through a section of the shaker screen to enhance the flow of drilling fluid through the section of the shaker screen and the separation of drilling fluid from drill cuttings and further maintain an effective flow of drill cuttings off the shaker. A method of separating components of a slurry of drilling fluids and solids has the steps of delivering the slurry to a shaker, flowing the slurry over a first screen and applying an effective amount of vacuum to a first portion of the first screen to remove the drilling fluids from the slurry without stalling the solids on the first screen.

A vacuum belt filter including a belt with a plurality of vacuum boxes, filter means being arranged to the vacuum boxes, drive means for moving the belt, and a suction station for creating an underpressure to the vacuum boxes at the suction station. In order to enable liquid-solid separation at low energy costs and long service interval of the vacuum belt filter, the filter means is in the form of a capillary filter, each vacuum box being provided with such a filter and each vacuum box being provided with an outlet having a check valve enabling a fluid flow from the inside space of the vacuum box to the outside of the vacuum box for creating an underpressure in the vacuum box when the suction station is connected to the vacuum box.

The present discloses a waste screening apparatus comprising: a main body; a waste screener vertically and tiltedly disposed in the main body to screen wastes in the input water and to allow waste-removed water to be discharged through water discharge holes defined in both side faces of the main body respectively, wherein the waste screener vertically circulates in a conveyor manner, wherein the input water is input to a front, rear and bottom of the waste screener; wherein the main body includes: both side walls having the water discharge holes defined therein respectively to allow waste-removed water to be discharged out from the waste screener therethrough; and a rear blocking wall disposed at a rear of the waste screener to be spaced from the waste screener, wherein the input water passes through front and rear portions of the waste screener with wastes being removed from the input water, and, then, is discharged out through the water discharge holes defined in the both side walls respectively.

Disclosed is a system for removing and collecting finely cut chips. The system can scrape and collect cutting oil and finely cut chips accumulated under a cutting apparatus using a scraper moving in a predetermined direction, separately discharge and reuse only cutting oil using a holed plate having holes smaller than finely cut chips, and separately collect and handle only the finely cut chips collected by the scraper.

An oleophilic separation apparatus has a rotatable metal cage and at least one oleophilic sieve in frictional engagement with the rotatable metal cage. The oleophilic sieve is made of an oleophilic material such that a bitumen phase adheres to the oleophilic sieve upon contact. A plurality of apertures in the oleophilic sieve allows aqueous phase to escape from the rotatable metal cage. A hot zone is provided that has at least one rotation member and a source of heat. The oleophilic sieve is in frictional engagement with the at least one rotation member. The hot zone heats the bitumen phase adhered to the oleophilic sieve to allow for collection of the bitumen phase.

A device and a method for thickening a slurry are disclosed. A pump is provided comprising an inner chamber, a pumping apparatus, an external wall, an inlet, and an outlet. The slurry comprises a solid and a liquid. The slurry enters the inner chamber through the inlet and is pumped and pressurized by the pumping apparatus through the inner chamber across a portion of the external wall comprising a porous wall, causing a portion of the liquid to be pressed through the porous wall as a liquid product stream and thickening the slurry into a thickened slurry stream. The thickened slurry stream leaves through the slurry outlet.
