20110198268 | HYBRID ROTARY SCREEN SEPARATOR - The present invention may be embodied as a rotary screen separator for processing feed material. A separator member defines a longitudinal axis, an input port, an output port, a fine perforation region, and a coarse perforation region. A collector structure defines a fine material output and a coarse material output. A support structure supports the separator member and the collector structure. A drive system rotates the separator member relative to the support structure. Operation of the drive system displaces feed material through the fine perforation region and the coarse perforation region. A first portion of the feed material flows through the separator member to the fine material output in the fine perforation region. A second portion of the feed material flows through the separator member to the coarse material output in the coarse perforation region. A third portion of the feed material flows through the output port. | 08-18-2011 |
20110253227 | SYSTEMS AND METHODS FOR CLEANING DAIRY FACILITIES - A cleaning system for a dairy facility comprising a rinse system including a rinse sprayer, a flush system comprising a process system for processing waste water to obtain processed water, a collection system connected between the dairy facility and the process system, and a flush sprayer. The rinse sprayer sprays rinse water in a first zone of the dairy facility, where the rinse water becomes waste rinse water after the rinse water has been sprayed in the first zone of the dairy facility. The flush sprayer sprays the processed water in a second zone of the dairy facility, where the processed water becomes waste processed water after the processed water has been sprayed in the second zone of the dairy facility. The collection system collects the waste rinse water and the waste processed water to form the waste water and directs the waste water to the process system. | 10-20-2011 |
20110309039 | PRE-SEPARATOR FOR A SCREEN SEPARATOR - A pre-separator for a screw press separator wherein the pre-separator increases the concentration of solid material in a water solid material mixture. The pre-separator is configured to have a frustoconical screen surface where a plurality of wiper blades engage the interior portion of the surface to provide de-watering action, and the plurality of blades are configured to reposition with respect to the center axis of the frustoconical surface to allow for engagement between the interior surface of the frustoconical screen, and the wiper blades. | 12-22-2011 |
20120132734 | SYSTEMS AND METHODS FOR PROCESSING ANIMAL WASTE - A flush system for processing waste slurry contains animal waste, comprising a primary separator, a primary digester, and a secondary digester. The primary separator separates the waste slurry into a first portion and a second portion. The primary digester digests the first portion. The secondary digester digests at least part of the second portion. A solids content of the first portion is higher than a solids content of the second portion. | 05-31-2012 |
20120138515 | SYSTEMS AND METHODS FOR EXTRACTING PARTICULATE FROM RAW SLURRY MATERIAL - A processing system for processing raw slurry material comprising a barrel member defining a feed portion, a processing chamber, and an outlet opening, at least one pre-processing member, and at least one pre-processing opening formed in the barrel member adjacent to a first portion of the pre-processing member. As the barrel member rotates, the at least one pre-processing member transports at least a portion of the raw slurry material such that at least some of the heavy particulate material in the raw slurry material is transported to the outlet opening, at least some of the liquid material in the raw slurry material is allowed to flow back towards the feed portion, and at least some of the liquid material and at least some of the light particulate material is allowed to flow through the at least one pre-processing opening. | 06-07-2012 |
20130299395 | Hybrid Rotary Screen Separator - A rotary screen separator for processing feed material comprising liquids and solids, the rotary screen separator comprising a separator member, a collector structure, a drive system, and first and second vane structures. The separator member defines a first perforation region and a second perforation region. The collector structure defines a first material output and a second material output. The vane structures are supported relative to the separator member such that operation of the drive system to rotate the separator member causes the first vane structure to displace the feed material through the first perforation region at a first material displacement rate and the second vane structure to displace the feed material through the second perforation region at a second material displacement rate. The first material displacement rate is greater than the second material displacement rate. | 11-14-2013 |
20140083957 | Systems and Methods for Extracting Sand from Raw Slurry Material - A processing system for processing raw slurry material comprises a barrel member defining a processing chamber, at least one intermediate opening, and an outlet opening, a trough system arranged to contain the raw slurry material, at least one transport member, and a drive system. As the drive system rotates the barrel member, the at least one transport member transports at least a portion of the raw slurry material from the trough system and through the processing chamber such that at least a first portion of the raw slurry material is transported to outlet opening, at least a second portion the raw slurry material exits the processing chamber through the intermediate opening, and at least at third portion of the raw slurry material is allowed to flow back towards the trough system. | 03-27-2014 |
20140091043 | Systems and Methods for Separating Solids from Liquids - A separator system for separating feed material into a liquid component and a solids component. The separator system has a roller system supported adjacent to a feed chamber. The roller system comprises a base roller and a press roller. Base perforations are formed in the base roller. The base roller is supported such that a first portion of the base roller is in contact with the feed material within the feed chamber such that a liquids portion of the feed material may flow through the perforations in the base roller. The base roller is rotated such that the base roller removes a solids portion of the feed material from the feed chamber in a solids mat on the surface of the base roller. The press roller engages the solids mat on the base roller to force liquids in the solids mat through the base perforations in the base roller. | 04-03-2014 |
20150053594 | Hybrid Rotary Screen Separator - A rotary screen separator for processing feed material comprising liquids and solids, the rotary screen separator comprising a separator member, a collector structure, and first and second vane structures. The separator member defines a first perforation region and a second perforation region. The collector structure defines a first material output and a second material output. The vane structures are supported relative to the separator member such that rotating the separator member causes the first vane structure to displace the feed material through the first perforation region at a first material displacement rate and the second vane structure to displace the feed material through the second perforation region at a second material displacement rate. The first material displacement rate is greater than the second material displacement rate. | 02-26-2015 |
20150083672 | Systems and Methods for Extracting Sand from Raw Slurry Material - A processing system for processing raw slurry material has a barrel member, at least one transport member, and at least one separator member. The barrel member defines a processing chamber and at least one intermediate opening. The processing chamber defines a pre-processing portion and a separator portion. The at least one transport member is arranged within the pre-processing portion of the processing chamber. The at least one separator member is arranged within the separator portion of the processing chamber and configured to define at least one separator gap. As the barrel member rotates about a longitudinal axis thereof, the at least one transport member transports at least a portion of the raw slurry material through the pre-processing portion of the processing chamber, and the at least one separator member transports at least a portion of the raw slurry material through the separator portion of the processing chamber. | 03-26-2015 |
