A single negative pressure shale shaker

Vibration trajectory：straight line

Number of screens（piece）：4

Applicable screen mesh size:1050×700

Peculiarity:

(1) The liquid and gas are different channels, which are not affected by the mud on the sieve surface, and can continuously form negative pressure suction to ensure the formation of negative pressure on the sieve surface at any time.

(2) There is negative pressure on the 3# and 4# screens, the negative pressure area is large, the rock chips are sucked more dry, and the liquid content is lower.

(3) Water-based and oil-based mud are applicable.

(4) Simple structure, convenient maintenance and maintenance. When the negative pressure is not opened, it is a conventional vibrating screen, and the accessories are the same as the conventional vibrating screen.

(5) Negative pressure is adjustable. Not only can the vacuum level of the entire negative pressure screen be adjusted, but also the vacuum level of each screen can be adjusted individually.

(6) Due to the simultaneous action of vibration and negative pressure, high-mesh screens can be used, and the MAX mesh can reach 375 meshes.

(7) The return liquid gas content of negative pressure suction is low, and there is no need to add a liquid gas separation device.

(8) The inclination angle of the sieve box adopts worm gear + spiral screw pair stepless adjustment, which can be adjusted in any position according to the slurry flow length of the sieve surface, which is convenient, fast and labor-saving.

(9) The wedge block adopts rack and pinion structure, which is fast and convenient to load and unload.
