Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] Separator of the present invention is made up of base 2, upper and lower bearing 10,4, drum 16, drum shaft 18 etc. Referring to accompanying drawing 1 , the bracket 15 is fixedly installed on the base 2 .

[0013] The drum shaft 18 is a hollow shaft, supported and installed in the center of the bracket 15 by the upper bearing 10 and the lower bearing 4, and its upper end is connected with the upper joint. It is connected with the lower joint, and the contact between the lower joint and the drum shaft 18 is provided with a sealing ring 3 . An oil outlet 11 is arranged on the upper joint, and the oil outlet 11 communicates with the upper joint. The lower joint is provided with an oil inlet 1, and the oil inlet 1 communicates with the lower joint. The rotating drum 16 is connected with the rotating drum shaft 18 and placed horizontally at the cen...

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...
