Description

technical field

[0001] The invention relates to the technical field of separation of oil sand from petroleum, in particular to an oil sand separator which can separate fine sand particles from petroleum and quickly discharge the hardened sand blocks after separation, as well as sand discharge and sealing. Methods. Background technique

[0002] The exploited oil contains a lot of sand, among which the larger particles of sand can be easily separated by a centrifuge, and the separated sand can be discharged out of the centrifuge. But also contain a lot of fine grains of sand in oil, it is difficult to discharge it out of the machine with existing devices. The reason is that the oil has a high density and a high viscosity, and the fine sand particles in the oil have a small particle size and are in a suspended state in the oil, and cannot be separated by gravity. If the existing centrifuge (such as a horizontal screw centrifuge) is used ) Since the sand grains are very fine a...
