| 20090200248 | Belt Filter Apparatus - The invention concerns a belt filter apparatus comprising a first belt filter section on which a mixture of fine material and a liquid can be placed hydraulically to create partially dry fine material and a second belt filter section on which the partially dry fine material can be placed in order to undergo a second drying cycle. The belt filter apparatus also includes means for mechanically placing the partially dry fine material from the first belt filter section onto the second belt filter section as well as a liquid collection arrangement for providing fluid communication between the first and second belt filter sections and a vacuum. In use the vacuum dries the fine material by drawing liquid through the permeable fabric of the first and second belt filter sections and into the liquid collection arrangement. The belt filter apparatus includes an agitator formation for increasing the permeability of the fine material to enhance the ability of the liquid to be released from the fine material and be collected by the liquid collection arrangement. | 08-13-2009 |
| 20100072145 | MEMBRANE TABS - A candle filter includes an end portion, elongate interior structure extending from the end portions and defining a space for a fluid, and a membrane fabric for filtering a substance from the fluid as the fluid passes through the membrane fabric and into the space defined by the interior structure. The membrane fabric extends around the interior structure and to the first end portion. The membrane fabric includes at least one extending tab segment for manipulating to move the membrane fabric relative to the elongate interior structure. An associated method provides an operational candle filter. | 03-25-2010 |
| 20100224574 | METHOD AND APPARATUS FOR SEPARATING PARTICLES FROM A LIQUID - A method and device for separating particles from a liquid having particles therein, using a filter sized to permit the liquid to flow through pores, while retaining a substantial portion of the particles on the filter, with an absorbent layer contacting the back of the filter to facilitate liquid movement away from the particles. | 09-09-2010 |
| 20130001175 | COOLANT FILTRATION SYSTEM AND METHOD FOR METAL WORKING MACHINES - A coolant filtration system and method for use with one or more metal working machines. The system includes a housing, pump, conveyer assembly, drum assembly, and centrifugal separator. The housing includes a tank that receives and holds coolant coming out of the one or more metal working machines. The pump is used to drive the coolant through the coolant filtration system. A part of the conveyer assembly is disposed within the housing in order to carry-away workpiece chips from the coolant. The drum assembly is located near the conveyer assembly in order to filter the coolant. The centrifugal separator receives coolant processed by the conveyor and drum assemblies. The system can further include one or more fine filters for additional filtering of the coolant outputted by the centrifugal separator. | 01-03-2013 |
| 20130213904 | INDUSTRIAL SEPARATOR AND DEWATERING PLANT - An industrial separator and dewatering plant delivers an influent to an inclined rotating filter belt for filtering out solid matter from the influent. A wash water is sprayed on the return portion of the belt to dislodge residual solid matter captured within the belt. A dewatering portion has an auger screw positioned for receiving the solid matter and the wash water. The auger screw transports the wash water and the solid matter to a compression cage where water is driven out of the solid matter by compression as it exits the plant. Alternately, the solid matter and wash water may be delivered together to a plant exit. Excess wash water is able to drain from the auger screw through a separate drain. | 08-22-2013 |
| 20140144851 | MATERIALS HANDLING AND TREATMENT - A belt filter apparatus for treating material to separate solid and liquid components comprises an endless belt structure adapted to circulate around a path incorporating guide roller structures around which the belt structure passes. The endless belt structure comprises an elongate belt portion of water permeable material, and has two opposed longitudinal edges. A zipper releasably connects the two longitudinal edges together to form a tubular structure with a flexible sidewall. The circulating path includes an assembly zone where the longitudinal edges are brought together and connected by the zipper to form the tubular structure, and a disassembly zone at which the zipper is released to separate the longitudinal edges and open the tubular structure. Means are provided for compressing a portion of the tubular structure to express liquid from the material contained in the tubular structure. The liquid discharges from the tubular structure through the water permeable belt portion. | 05-29-2014 |
| 20140353261 | KCR SCREEN CHANGER - A screen changer for filtering a thermoplastic material heated to a flowable state comprises a filter head defining a melt passage for the heated thermoplastic material, and a guide channel having entry and exit sections arranged on opposite sides of the melt passage. The entry and exit sections are configured and arranged to direct a continuous screen filter along a guide path extending transversely across the melt passage from an entry side to an exit side of the filter head. The screen filter is incrementally advanced along the guide path. An internal first cavity is provided in the filter head on an upstream side of the filter screen and at a juncture of the melt passage and the exit section of the guide channel. The first cavity is positioned to receive contaminants accumulated on the screen filter. A waste removal mechanism removes contaminants from the first cavity. | 12-04-2014 |
