A shale shaker system. The system includes a fluid transport pipe configured to receive a stream of drill cuttings and fluid returns from a wellbore during a drilling operation; an analysis module configured to receive at least a portion of the stream of drill cuttings and fluid returns at an inlet; a cuttings chute configured to receive at least a portion of the stream of drill cuttings and fluid returns from an outlet of the container, and deliver them to a screen box; and one or more screens for filtering drill cuttings from the fluid returns. The analysis module comprises logging sensors configured to operate while drill cuttings are moving through the system. The logging sensors communicate with a processor to determine characteristics of the drill cuttings in real time. A method for analyzing drill cuttings at a well site is also provided.

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.

A disclosed screen assembly includes a frame and a tensioned molded polyurethane screen attached to the frame. The frame has a perimeter that is a circle, square, rectangle, triangle, pentagon, hexagon, or other multi-sided polygon, and the screen may have similarly shaped apertures. The frame includes a support grid structure bounded by the perimeter and the screen may either be attached only to the perimeter of the frame, or may be attached to the perimeter of the frame and to one or more locations of the support grid structure. The screen may include uniaxial or biaxial reinforcement members that are integrally molded with the screen, and the tensioned screen may include tension along a direction that is parallel to, or perpendicular to, a direction of the reinforcement members. A disclosed method includes applying tension to a molded polyurethane screen and attaching the tensioned molded polyurethane screen to the frame.

A continuous sieving apparatus is described. The continuous sieving apparatus includes an inclined sieve surface attached to a wall. The inclined sieve surface is inclined with respect to a horizontal axis for pupae to continuously flow across down the incline. A set of openings is formed in the sieve surface so as to define a set of pathways extending through the sieve surface. The set of opening are defined by a length dimension that is greater than a width dimension. When the inclined sieve surface is submerged in a liquid, a first pupa having a first cephalothorax width that is less than the width dimension is free to move through any one of the set of openings, and a second pupa having a second cephalothorax width that is greater than the width dimension is prevented from moving through the set of openings.

The present disclosure discloses a wave-shaped polyurethane high-frequency linear vibrating screen mesh, which solves the problems of unobvious layering and poor screening effect of the existing screen mesh. The wave-shaped polyurethane high-frequency linear vibrating screen mesh comprises a side blind area and a screening area. The screen area is composed of wave-shaped injection molding polyurethane screen pieces. Materials roll forward along the direction of material flow in a wavy manner. Clamping grooves are formed in the blind area, which can be in buckle fit on rail seats of a small beam of a screening machine. The screen gap direction of the screening area is consistent with the direction of the material flow. Through the arrangement of a wave-shaped screen mesh surface, the wave-shaped polyurethane high-frequency linear vibrating screen mesh effectively optimizes the running state of the materials, and promotes effective layering of coarse and fine materials.

A modular, pre-tensioned, self-cleaning screening panel having a frame and at least one pre-tensioned wire that is fastened to the frame.

A screening apparatus includes a vibrating screen assembly that includes a screen and a vibrating mechanism operable on the screen to cause vibration of the screen, the screen having a feed end and a discharge end. At least one shield member is positioned on the screen and is configured to cover part of the screen between the feed end of the screen and a position intermediate the feed and discharge ends of the screen, such that particulate material for screening by the screen can be fed on to the, or each, shield member, the, or each shield member being positioned on the screen so that a vibrational pattern of the screen is imparted to the shield member. An adjustment mechanism is operatively engaged with the, or each, shield member to adjust a position of a discharge end of the, or each, shield member relative to the discharge end of the screen.

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.
