Example 1
As shown in fig. 1, 3 to 7, the compressor exhaust device includes an exhaust pipe 10, the exhaust pipe 10 is installed on a compressor housing 40 in a penetrating manner, the exhaust pipe 10 has a movable pipe section 11 which is movably installed, at least a part of the movable pipe section 11 is located in the compressor housing 40, the movable pipe section 11 has an air inlet 1111 for exhausting air, and air in the compressor housing 40 flows into the exhaust pipe 10 through the air inlet 1111 and is discharged to the outside of the compressor housing 40, and the movable pipe section 11 is rotatably or swingably installed so that the direction of the air inlet 1111 is changed when the movable pipe section 11 moves.
In this embodiment, the movable pipe section 11 is disposed inside the compressor housing 40 to reduce the circulation rate of the compressor oil, specifically, when the gas inside the compressor housing 40 flows, the movable pipe section 11 disposed movably can change the direction of the air inlet 1111 along with the direction of the gas flow, so as to prolong the residence time of the gas in the compressor housing 40, slow down the efficiency of gas exhaust, and further prolong the time of oil-gas separation, thus, the gas can be fully stirred for oil separation, so that more compressor oil can be separated from the gas, the oil separation efficiency is improved, and thus, a large amount of compressor oil is prevented from being discharged to the outside of the compressor housing 40 along with the gas from the air inlet 1111, and the circulation rate of the compressor oil is reduced by controlling the discharge amount of the gas which is not subjected to the oil-gas separation.
In the present embodiment, the movable pipe section 11 is rotatably or swingably provided so that the orientation of the air inlet 1111 is changed when the movable pipe section 11 moves, thereby improving the oil separation efficiency by controlling the discharge volume of the gas not subjected to the oil-gas separation. Specifically, one end of the exhaust pipe 10 extends into the compressor housing 40, the other end extends out of the compressor housing 40, the movable pipe section 11 is arranged at one end of the exhaust pipe 10 extending into the compressor housing 40, and the air inlet 1111 can be arranged at the end of the movable pipe section 11 or on the side wall of the movable pipe section 11, so that when the movable pipe rotates or swings relative to the compressor housing 40, the air inlet 1111 can change the opening direction accordingly, thereby prolonging the time of exhausting the air in the compressor housing 40 from the exhaust pipe 10, improving the oil distribution efficiency and the trimming oil return amount. In the present embodiment, the movable pipe section 11 is rotatably provided, so that the movable range of the movable pipe section 11 is increased, and the flexibility of the movement of the movable pipe section 11 is improved.
In the present embodiment, the air inlet 1111 is located at an end of the exhaust pipe 10, and air enters the exhaust pipe 10 from the air inlet 1111 and is discharged from the inside of the compressor housing 40 along the extending direction of the exhaust pipe 10, and in the present embodiment, the movable pipe section 11 is bent in a pipe shape such that the air inlet 1111 can be provided on a section of bent pipe far from the center of rotation, and the air inlet 1111 can change the opening direction when the movable pipe section 11 rotates or swings, thereby prolonging the residence time of the air inside the compressor housing 40.
As shown in fig. 1, in the present embodiment, the compressor discharge apparatus further includes a windward plate 20, the windward plate 20 being disposed on the movable pipe section 11, the windward plate 20 having a windward face 21. Specifically, the windward plate 20 is attached to the peripheral side of the movable pipe section 11, the windward plate 20 is plate-shaped along the extending direction of the movable pipe section 11, and the windward surface 21 is a side of the windward plate 20 away from the movable pipe section 11, so that when the air in the compressor housing 40 flows to generate an air flow, the air flow impacts the windward surface 21 to generate an impact force, so that the windward plate 20 drives the movable pipe section 11 to rotate, and the direction of the air inlet 1111 is gradually parallel to the air flow direction, thereby reducing the discharge of the air without oil-gas separation. In this embodiment, the windward plate 20 is rectangular, but may be other polygonal plates, or may be irregularly shaped plates, so that the windward plate 20 can be impacted by the air flow inside the compressor housing 40 to drive the movable pipe section 11 to move.
As shown in fig. 6 and 7, in this embodiment, the air is rotated along the wall surface of the compressor housing 40 by the rotation of the main balance weight 50, and when the windward side 21 is considered to be parallel to the plane in which the air inlet 1111 is located, that is, when the windward side 21 is perpendicular to the direction of the air inlet 1111, the air moves along the plane in which the air inlet 1111 is located, so that the windward side 21 cannot drive the movable pipe section 11 to rotate by the impact of the air flow to change the direction of the air inlet 1111, and the movable pipe section 11 is disabled, so that the exhaust pipe 10 is equivalent to the conventional static exhaust pipe 10, and the air can still be rapidly discharged from the compressor housing 40 by centrifugal force, so that the windward side 21 and the plane in which the air inlet 1111 are located are arranged at an angle, so that the windward side 21 can always be impacted by the air flow to adjust the direction of the air inlet 1111, and the direction of the air inlet 1111 is kept parallel to the direction of the air flow.

As shown in fig. 1, in this embodiment, in order to ensure that the windward plates 20 can receive enough force to drive the movable pipe section 11 to rotate, the windward plates 20 are provided in plurality, and the windward plates 20 are disposed on two sides of the movable pipe section 11 in a group of two windward plates 21 in parallel, so as to ensure that the impact forces of the airflows received by the two windward plates 21 do not collide, thereby avoiding mutual cancellation of the impact forces. The present embodiment provides a set of windward plates 20, that is, two windward surfaces 21, which are disposed on the sides of the two windward plates 20 away from each other, so as to ensure the effectiveness of the windward plates 20. Of course, according to actual needs, the windward plates 20 may be arranged in multiple groups, so as to increase the windward area 21, ensure the rotation of the movable pipe section 11, and ensure that the windward plates 20 can be arranged along the extending direction of the movable pipe section 11 and be parallel to each other.
