2results about How to "No overflow loss" patented technology

The utility model relates to leaching device, concretely relates to scrape flat compaction's solid -liquid separation discharge leaching device. Including leaching ware, leaching ware is by the fixed cylinder wall of outside, the rotating shaft of inside center and is divided a plurality of leaching grid by separating plate and is formed, leaching ware bottom is equipped with the oil collecting hopper, the oil collecting hopper is by the grid plate and is separated into feed grid, a plurality of oil collecting grid, liquid supplementing grid, overflow grid, scraping flat grid, discharge grid in turn along the rotating direction of rotating shaft, leaching grid bottom is equipped with fixed false bottom, discharge grid connects solid discharge conveying device, solid discharge conveying device opens branch line solid conveying device, and the discharge end of solid conveying device is located above the leaching grid corresponding to overflow grid, and the scraping flat mechanism is equipped above the leaching grid above scraping flat grid. The utility model discloses through setting up scraping flat mechanism and compacts the solid material scraping flat, further reduces the gap between solids, makes solvent overflow as far as possible, reduces the pressure of subsequent solid -liquid separation.

The present invention discloses a wheel-leg robot and a leg joint driving device thereof, belonging to the technical field of wheel-leg robots, and including a hydraulic control system; the hydraulic control system includes a hydraulic cylinder, a piston rod, a main oil circuit, a secondary oil circuit, a servo motor and a hydraulic pump; a load-bearing chamber and a non-load-bearing chamber are arranged in the hydraulic cylinder; the piston rod separates the load-bearing chamber and the non-load-bearing chamber; the servo motor is used to drive the hydraulic pump; the non-load-bearing chamber, the main oil circuit, the hydraulic pump, the secondary oil circuit and the load-bearing chamber are connected in sequence; the extension of the piston rod relative to the hydraulic cylinder changes with the change of the hydraulic oil capacity in the load-bearing chamber and the non-load-bearing chamber. The wheel-leg robot and the leg joint driving device of the present invention have no overflow loss, no throttling loss, save system power, and the hydraulic system has high transmission efficiency, high energy utilization, good buffering performance and long service life.
