摘要： A vibrator separator system has a vibrator separator position and a vibratory basket, a screen assembly positioned in the vibratory separator, and a vibration amplifier coupled to the vibratory separator. The vibratory basket has sides arranged in spaced relation to each other. The vibratory separator has at least one motor affixed thereto. The screen assembly extends between an inlet end and a discharge end of the vibratory basket. The motor is cooperative with the screen assembly so as to impart a vibration frequency to the screen assembly. The vibration amplifier is positioned beneath the screen assembly. The vibration amplifier is cooperative with the screen assembly so as to exert a force against a portion of an underside of the screen assembly.

摘要： 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.

摘要： An apparatus and method for facilitating recovery of lubrication beads is provided. The apparatus includes a hydrocyclone, for separating drilling fluid into a high density stream and a low density stream containing a major portion of the lubrication beads; a receiving pump, for pumping drilling fluid to the hydrocyclone; a discharge pump, for pumping the high density stream from the lower end of the hydrocyclone to further processing; and a hose for flowing the low density stream from the upper end of the hydrocyclone to the cleaned fluid handling system. A method for integrating the apparatus for facilitating recovery of lubrication beads from a drilling fluid into a solids control apparatus includes positioning an end of a first hose to receive the drilling fluid; arranging an end of a second hose in communication with the first shaker's filter screen; and setting an end of a third hose to empty into the cleaned fluid handling system. A method for facilitating recovery of lubrication beads from a drilling fluid by a shaker system includes receiving drilling fluid in a hydrocyclone; separating the drilling fluid into a high density stream and a low density stream containing a major portion of the lubrication beads; and flowing the high density stream to a first shaker of the shaker system, and directing the low density stream to a second shaker of the shaker system.

摘要： A sieve system includes a sieve for screening material by selectively passing first particles and not passing second particles of the material based on respective dimensions of the particles relative to dimensions of screening apertures in the sieve. A holding container feeds material to the sieve and a fines container receives the first particles screened by the sieve. A first fines container load is measured at a first time, and a second fines container load is measured at a second time. A fines rate is determined by a rate of change of the fines container load based on the measured first and second fines container loads and the first and second times. An operating condition of the sieve system is based on the fines rate and may provide an indication that the operation of the sieve, another component, or the sieve system as a whole is acceptable or unacceptable.

摘要： The present invention relates generally to the field of sifters. More specifically, the present invention relates to a sifter lid device. The device is comprised of a body further comprised of a funnel area and a continuous opening in the top surface of the body that receives a sifter insert. The device can be placed on a container such that the contents of the container are sifted through the sifter insert and then can be poured using the funnel area into a secondary location or other container as desired. The sifter insert is further removable and may have a plurality of screen spacings. The device may also be comprised of a lid that covers the sifter insert when the device is not in use but is still attached to a container.

摘要： A method for determining a screen break may include obtaining a fluid stream after a screening system in a drilling process; placing the fluid stream into a screen break detector; obtaining a pressure within a well of the screen break detector when the screening system is in a first state; obtaining a pressure within the well of the screen break detector when the screening system is in a second state; determining a differential pressure within the well of the screen break detector obtained when the screening system is in the second state compared to the pressure when the screen break is in the first state; and transmitting a notification to an operator when the pressure within the screen break detector obtained when the screening system is in the second state is greater than the pressure within the screen break detector when the screening system is in the first state.
