Gauge well mixer
View Patent ↗This gauge well mixer works off of the differential pressure in a storage tank and gauge well. Slot covers with dividers are installed in the gauge well. The slot covers and dividers are staggered for better mixing. The gauge well has a vertical interior space extending the length of thereof; wherein the slots open into the vertical, interior space. A first horizontal divider is located in the vertical, interior space below a first slot; and a second horizontal divider is located in the vertical, interior space above a second slot. The slot covers are installed on slots located between the first slot and the second slot.
1. An apparatus comprising a gauge well and storage tank;
wherein the gauge well has a vertical interior space extending the length of thereof;
a first slot open into the vertical, interior space;
a first horizontal divider located in the vertical, interior space below first slot;
a second slot open into the vertical, interior space; and
a second horizontal divider located in the vertical, interior space above the second slot;
thereby forming a mixing zone in the vertical zone interior space between the first horizontal divider and the second horizontal divider;
the gauge well being attached to the storage tank and having slots extending along the length thereof;
a floating roof resting on the liquid stock in the storage tank and having a seal between the roof and the gauge well;
the gauge well extending above the maximum level of liquid stock in the storage tank; and
a vapor seal to minimize vapor loss from the gauge well.
2. An apparatus according to claim 1 further comprising:
a plurality of slots located between the first slot and the second slot wherein each slot of the plurality is open into the vertical, interior space; and
a plurality of slot covers wherein the slot covers cover the slots located between the first slot and the second slot.
3. An apparatus according to claim 2 wherein the plurality of horizontal dividers and the plurality of slot covers are arranged to form a plurality of mixing zones.
4. An apparatus according to claim 1 further comprising a plurality of slots open into the vertical, interior space, wherein each slot of the plurality is located below the first horizontal divider.
5. An apparatus according to claim 1 further comprising a plurality of slots open into the vertical, interior space, wherein each slot of the plurality is located above the second horizontal divider.
