A tank arrangement, duplicate cross-sectional restrictions, side roller block, openable reaction roller, openable bottom seal, reaction axle, openable side seal, gate slot inserting steps and a stress reduction cross-sectional restriction are presented to implement an emerging movement type opening/closing gate equipped with advantageous torsion structure. The arrangement enables a gate body to be operated in submerged-body state, the cross-sectional restrictions can correspond to both high tide pressure and tide flow pressure which are different in qualities, the side roller block, the openable reaction roller and the openable bottom seal resolve spatial interference problems in gate operation, compact reaction axles which endure big load enables cross-sectional restriction points at a narrow gap in a storage space, the openable side seal and the gate slot inserting steps prevent side seal rubber from damage and the stress reduction cross-sectional restriction can cut high tide pressure torsion moment by more than 50%.

A method for enriching lithium from a lithium clay includes the following steps (1) the raw ore were crushed to produce fine particles, (2) performing rougher on the fine particles by adding ferric sulfate or ferric nitrate, sodium oleate, and cocoamine to obtain rough concentrate and rough tailing, (3) finely separating the rough concentrate to obtain the first part of concentrate, (4) re-grinding the rough tailing by ball mill, (5) performing rougher on the reground tailing to obtain reground rough concentrate and re-ground rough tailing, (6) performing cleaner on the reground rough concentrate to obtain the second part of concentrate, and (7) performing scavenger on the reground rough tailing to obtain the cleaned tailing.

The present invention relates to a retractable floodwall unit that comprises a foundation unit having a plurality of guide tracks along side walls of the foundation unit, a floodwall panel stowed in the foundation unit; and a power system for raising and lowering the floodwall panel. The foundation unit includes a first housing unit enclosing an actuator of the power system, and the floodwall panel includes a plurality of guides that mate with the guide tracks of the foundation unit.

A control gate for a channel or pond adapted to be installed across a channel for liquids. The control gate includes: at least two panels hingedly connected together, the panels having opposing sides in sealing engagement with side walls of the channel, a lowermost panel being in sealing engagement with the floor of the channel. The panels are substantially vertically aligned in a fully closed position of the control gate. At least one first lifting element is connected to the top of an uppermost panel and is adapted to lower and raise the uppermost panel relative to its hinged connection in a concertina manner to provide an overshot position for the control gate. At least one second lifting element is connected to the bottom of the lowermost panel to raise and lower the lowermost panel from the floor of the channel to provide an undershot position for the control gate.

A water gate comprising at least one curved surface, the curved surface extending laterally between two sides; at least one web extending between the two sides of the curved surface.

An automated irrigation gate system and method for regulating water levels in irrigation channels automates control of water through an irrigation channel based upon water levels, water flow rate, and ambient environmental conditions in the irrigation channel and an adjacent agricultural region. The system comprises at least one irrigation regulation device operationally attached to the irrigation channel. The irrigation regulation device regulates fluid flow through a channel opening in the irrigation channel through use of a gate. A fluid sensor monitors the level of fluid in the channel and an adjacent agricultural region. The fluid sensor also monitors the flow rate of the fluid flowing from the channel to the region. An environmental sensor monitors environmental conditions ambient to the region. A control portion comprises a processor that calculates the data to selectively displace the gate between an open position and a closed position relative to channel opening.
