2results about How to "Improve sand removal efficiency" patented technology

A spiral sand removing machine capable of removing harmful solid phases in drilling fluid is characterized in that a feeding box is installed on a base, an overflow pipe and a stirrer motor are installed on the upper portion of the feeding box, and a feeding pipe and a sand discharging pipe are installed on the lower portion of the feeding box and connected with the spiral sand removing machine. The spiral sand removing machine is structurally characterized in that a spring supporting vibration frame is mounted on a base; a central shaft is mounted on a vibrating frame as a feeding pipe, bearing seats and eccentric wheels are mounted at two ends of the central shaft, a spiral screen pipe is mounted in the middle of the central shaft, and a driving motor is mounted below the eccentric wheels to drive the eccentric wheels, the central shaft and the spiral screen pipe to rotate to generate centrifugal force and vibrating force to throw drilling fluid out of a screen to flow into a circulating tank; and harmful solid phases and drilling cuttings are discharged out of the spiral screen pipe and are discharged into the sand setting tank. The technical requirement of purifying the drilling fluid is met.

The utility model discloses a circulating desanding device for sewage treatment, and relates to the technical field of sewage treatment, the circulating desanding device comprises a fixed bottom plate and a filter assembly, the left end of the upper surface of the fixed bottom plate is provided with a supporting stand column, and the filter assembly is arranged at the top of the supporting stand column; the filtering assembly comprises a filtering tank, a sand filtering net, an impurity filtering net, a drainage valve, a water conveying pipe, a drainage pump, a drainage pipe and a sealing door, the filtering tank is arranged at the top of the supporting stand column, the sand filtering net is installed at the upper end in the filtering tank, the impurity filtering net is arranged below the sand filtering net, and the drainage valve is installed at the bottom of the filtering tank. According to the circulating sand removing device for sewage treatment, through the filtering assembly, gravel and other impurities in sewage can be further intercepted and filtered through multiple filtering mechanisms, the sand removing efficiency is improved, meanwhile, the filtering mechanisms are conveniently cleaned, blockage is prevented, through the draining assembly, the gravel can be drained through the device, and the filtering efficiency is improved. Therefore, the water can be conveniently recycled.
