Abstract
An apparatus may include: a shaker body; a shaker screen disposed within the shaker body; and one or more air nozzles disposed within the shaker body, wherein the one or more air nozzles is positioned below the shaker screen, and wherein the one or more air nozzles is operable to deliver a pressurized stream of air to at least a portion of a bottom of the shaker screen.
Claims20
A method comprising:
- providing a shaker comprising:
- a shaker body;
- a shaker screen disposed within the shaker body;
- a sensor disposed within the shaker body, wherein the sensor comprises a plurality of force transducers and wherein each of the plurality of force transducers is positioned below the shaker screen;
- and
- one or more air nozzles disposed within the shaker body, wherein the one or more air nozzles is positioned below the shaker screen to deliver a pressurized stream of air to at least a portion of a bottom of the shaker screen;
- measuring a signal generated by the sensor;
- correlating the signal to a screen condition, wherein the step of correlating the signal to the screen condition comprises correlating the signal to a screen blinding condition;
- and
- performing a screen operation based on the screen condition, wherein the step of performing the screen operation comprises directing the one or more air nozzles to a portion of the shaker screen comprising the screen blinding condition.
7 more elements
A method comprising:
- providing a shaker comprising:
- a shaker body;
- a shaker screen disposed within the shaker body;
- two or more pumps, wherein the two or more pumps are individually fluidically connected to two or more fluid chutes which are operatively connected to a bottom of the shaker screen, and wherein the two or more pumps are operable to provide a vacuum pressure to the bottom of the shaker screen;
- and
- a sensor disposed within the shaker body, wherein the sensor comprises a pressure transducer operatively coupled to the two or more fluid chutes;
- measuring a signal generated by the sensor;
- correlating the signal to a screen condition, wherein the step of correlating the signal to the screen condition comprises correlating the signal to a screen blinding condition;
- and
- performing a screen operation based on the screen condition, wherein the step of performing the screen operation comprises controlling the two or more pumps to change the vacuum pressure on the bottom of the shaker screen.
7 more elements
A method comprising:
- providing a shaker comprising:
- a shaker body;
- a shaker screen disposed within the shaker body;
- two or more venturis, wherein the two or more venturis are individually fluidically connected to two or more fluid chutes which are operatively connected to a bottom of the shaker screen, and wherein the two or more venturis are operable to provide a vacuum pressure to the bottom of the shaker screen;
- and
- a sensor disposed within the shaker body, wherein the sensor comprises a pressure transducer operatively coupled to the two or more fluid chutes;
- measuring a signal generated by the sensor;
- correlating the signal to a screen condition, wherein the step of correlating the signal to the screen condition comprises correlating the signal to a screen blinding condition;
- and
- performing a screen operation based on the screen condition, wherein the step of performing the screen operation comprises controlling a flow of pressurized gas to the two or more venturis to change the vacuum pressure on the bottom of the shaker screen.
7 more elements
A method comprising:
- providing a shaker comprising:
- a shaker body;
- a shaker screen disposed within the shaker body;
- two or more eductors, wherein the two or more eductors are individually fluidly connected to two or more fluid chutes which are operatively connected to a bottom of the shaker screen, and wherein the two or more eductors are operable to provide a vacuum pressure to the bottom of the shaker screen;
- and
- a sensor disposed within the shaker body, wherein the sensor comprises a pressure transducer operatively coupled to the two or more fluid chutes;
- measuring a signal generated by the sensor;
- correlating the signal to a screen condition, wherein the step of correlating the signal to the screen condition comprises correlating the signal to a screen blinding condition;
- and
- performing a screen operation based on the screen condition, wherein the step of performing the screen operation comprises controlling a flow of pressurized liquid to the two or more eductors to change the vacuum pressure on the bottom of the shaker screen.
7 more elements
A method comprising:
- providing a shaker comprising:
- a shaker body;
- a shaker screen disposed within the shaker body;
- two or more eductors, wherein the two or more eductors are individually fluidly connected to two or more fluid chutes which are operatively connected to a bottom of the shaker screen, and wherein the two or more eductors are operable to provide a vacuum pressure to the bottom of the shaker screen;
- a sensor disposed within the shaker body wherein the sensor comprises a pressure transducer operatively coupled to the two or more fluid chutes;
- and
- an eductor pump, wherein an inlet to the eductor pump is fluidically connected to the two or more fluid chutes, and wherein an outlet of the eductor pump is fluidically connected to an inlet of the two or more eductors and operable to provide a pressurized liquid to the two or more eductors;
- measuring a signal generated by the sensor;
- correlating the signal to a screen condition, wherein the step of correlating the signal to the screen condition comprises correlating the signal to a screen blinding condition;
- and
- performing a screen operation based on the screen condition, wherein the step of performing the screen operation comprises controlling a flow of the pressurized liquid to the two or more eductors to change the vacuum pressure on the bottom of the shaker screen.
