[0019] The technical solutions in the embodiments of the present invention will be described in detail below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] An online hydrocyclone lubricating oil abrasive particle concentrator comprises a lubricating oil concentrating chamber, a lubricating oil rotary drive mechanism, an oil inlet 3, an oil outlet 11, and an abrasive particle output port 15, wherein the oil inlet 3 is located at the upper part of the concentrator, the abrasive particle output port 15 is located at the bottom of the concentrator, and the oil outlet 11 is located between the oil inlet 3 and the abrasive particle output port 15.

[0021] The lubricating oil concentration chamber includes an oil-liquid separation area and an abrasive particle collection area. The oil-liquid separation area includes a main pipeline 7, a top end cover 2, and a central oil return ring 8. The abrasive particle collection area includes a secondary pipeline 12 and a bottom end cover 13. The lubricating oil rotation drive mechanism includes a rotating motor 1 and an impeller 6.

[0022] The rotating motor 1, the top end cover 2 and the impeller 6 are coaxially fixedly connected, the power source of the impeller 6 is the rotating motor 1, the rotating motor 1 is located above the top end cover 2, the impeller 6 is located below the top end cover 2, the main pipeline 7 is located above the central oil return ring 8, the auxiliary pipeline is located below the central oil return ring 8, and the abrasive particle collection area is connected to the oil separation area below through the central oil return ring 8.

[0023] The top end cover 2 is located at the top of the concentrator and is hollow in design, that is, the top end cover inner cavity 4. The oil inlet 3 is opened in the tangent direction of the side inner wall. The top end cover inner cavity 4 is connected to the outside through the oil inlet 3. The top end cover 2 has an annular cavity and the top end cover connecting groove 5 downward.

[0024] The central oil return ring 8 has a forward connecting groove 9 at its upper end and a backward connecting groove 10 at its lower end. The oil outlet 11 on the side is provided in the tangent direction of the inner wall of the side.

[0025] The bottom end cover 13 is located at the bottom of the concentrator, and a grinding particle outlet 15 is provided at the bottom center. The bottom end cover 13 is provided with an annular cavity and a bottom end cover connecting groove 14 upward.

[0029] The technical solution provided by the present invention has the following working principle:

[0030] Bernoulli principle: kinetic energy + gravitational potential energy + pressure potential energy = constant. The oil containing abrasive particles is injected into the inner cavity of the top end cover through the oil inlet, and the rotating motor drives the impeller to rotate. The rotation of the impeller drives the oil inside the main pipe to rotate, and the oil and abrasive particles flow to the bottom at the same time; the liquid close to the inner wall of the main pipe is subject to viscous resistance, the flow velocity is low, and the internal pressure is high. The oil near the axis of the main pipe has a high flow velocity and a low pressure. The abrasive particles are subject to centripetal force and converge at the axis position; when the oil and abrasive particles flow to the vicinity of the central oil return ring, a large amount of oil flows out from the oil return port, and the abrasive particles flow into the auxiliary pipe and the bottom end cover along the axis position, and flow out through the abrasive particle output port in the center of the bottom end cover.
