Figure 1-4. Screen Frame Assembly
The vibrator motors are attached directly to the screen frame and positioned over the screening
bed to maximize the G-forces transferred to the screen surfaces. Float mounts isolate the
vibratory motion of the screen frame from the support structure. The adjustable while drilling
(AWD) mechanism is a manually operated jack screw that allows the operator to adjust the
screen bed angle b2
°
and +8
°
to maximize fluid-handling and solids-removal.
The concave screen bed directs the feed material toward the center of the bed. The unique
screen retention system conforms the screens to the concave shape of the screen bed, which is
covered with oil-resistant cushions. Four screen panels are retained by retention pins that are
extended and retracted by compression assemblies—one for each panel—on the right side of the
screen frame. The pins are extended and retracted by manually operated torque tubes. A
removable handle, inserted into a socket on each torque tube permits the operator to extend and
retract the screen retention pins to alternately retain and release each screen panel. Retention
pins on the right side of the screen frame retain the screen panels by forcing the outer edges of
the panels inward, causing them to conform to the distinctive concave shape that characterizes
the HP-704 shaker, and locking them securely to the screen bed.
Vibrator Motors
Two continuous-duty vibratory motors deliver 7Gs of force to the screen frame. Opposing
electrical polarities cause the motors to rotate in opposite directions, thereby imparting linear
vibrating motion to the screen frame for proper conveyance of solids toward the discharge end of
the machine.
Hopper
The hopper (Figure 1-5) captures underflow from the screen panels. Mounting provisions are
included on the hopper for the feeder (optional) and electrical control box. In addition, the hopper
contains supporting members for the screen frame, AWD, desander, desilter, and other
components.
