Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.
As shown in fig. 1 to 7, the oil separator according to the embodiment of the present invention includes a cylinder 1, a reinforcing sheet 2, and an intake pipe 3.
The cylinder body 1 is provided with a jack setting area 7, an air inlet pipe jack 6 is arranged in the jack setting area 7, and the central axis of the air inlet pipe jack 6 deviates from the central axis of the cylinder body 1.
As shown in fig. 1, the cylinder 1 may be cylindrical, the cylinder 1 extends along an up-down direction, a jack setting area 7 is provided on a cylinder wall of the cylinder 1, the jack setting area 7 is a selected area on the cylinder wall of the cylinder 1, and the jack setting area 7 is provided on a top of the cylinder 1. The air inlet pipe jack 6 is arranged in the jack setting area 7, and the air inlet pipe jack 6 penetrates through the wall of the cylinder body 1.
As shown in fig. 3, the central axis of the air inlet pipe jack 6 penetrates through the wall of the cylinder 1 along the left-right direction, and the extending direction of the air inlet pipe jack 6 is the tangential direction of the corresponding position of the wall, so that centrifugal separation can be generated, and separation of oil drops and gaseous refrigerant is realized. The central axis of the cylinder 1 extends in the up-down direction, whereby the central axis of the cylinder 1 and the central axis of the intake pipe insertion hole 6 are arranged vertically, and the central axis of the cylinder 1 and the central axis of the intake pipe insertion hole 6 are arranged at intervals in the front-rear direction.
It will be appreciated that in other embodiments, the central axis of the air inlet pipe receptacle 6 may be arranged non-perpendicularly to the central axis of the barrel 1, for example, in fig. 1, the central axis of the air inlet pipe receptacle 6 may extend in a direction from top left to bottom right, or in a direction from bottom left to top right.
The reinforcing sheet 2 is fixed on at least one of the outer wall and the inner wall of the cylinder 1 and is located in the insertion hole setting region 7, and the air inlet pipe insertion hole 6 penetrates the reinforcing sheet 2.
Specifically, as shown in fig. 1, the reinforcing sheet 2 is fixed to the outer wall of the cylinder 1, and the reinforcing sheet 2 is located in the jack setting region 7, i.e., the outer peripheral contour of the reinforcing sheet 2 does not exceed the outer peripheral contour of the jack setting region 7. A part of the air intake pipe insertion hole 6 is formed in the reinforcing sheet 2, that is, the air intake pipe insertion hole 6 also penetrates the reinforcing sheet 2.
A part of the air intake pipe 3 is fitted in the air intake pipe insertion hole 6 and the air intake pipe 3 is welded with the cylinder 1 and the reinforcing sheet 2. As shown in fig. 5, the intake pipe 3 is inserted into the intake pipe insertion hole 6. The outer peripheral wall of the air inlet pipe 3 is in sealing welding connection with the hole wall of the air inlet pipe jack 6, so that the air inlet pipe 3 and the barrel 1 are fixedly connected, and good sealing performance is achieved between the air inlet pipe 3 and the air inlet pipe jack 6, and leakage is avoided. Alternatively, the end of the air inlet pipe 3 for inserting the air inlet pipe insertion hole 6 is flush with the inner peripheral wall of the cylinder 1. This saves cost and also prevents the end from being inserted into the cylinder 1 to affect the air flow circulation in the cylinder 1, thereby causing excessive noise.
According to the oil separator disclosed by the embodiment of the invention, as the reinforcing sheet 2 is additionally arranged, the length of the air inlet pipe jack 6 is increased, so that the contact area between the air inlet pipe 3 and the hole wall of the air inlet pipe jack 6 is increased, and the strength of a fixed structure is enhanced. In addition, when the air inlet pipe 3 and the cylinder body 1 are welded and fixed, the welding flux penetration is not limited by the wall thickness of the cylinder wall, and the welding flux can be simultaneously melted into the reinforcing sheet 2 and the cylinder wall, so that on one hand, the strength of the connecting structure of the air inlet pipe 3 and the cylinder body 1 is further enhanced, the fatigue fracture and the leakage risk of the welding position of the air inlet pipe 3 and the cylinder wall are reduced, and on the other hand, the corrosion resistance of the welding position is enhanced due to the increase of the welding flux penetration, and the use reliability of the oil separator is further improved.
In some embodiments, the reinforcing sheet 2 is welded to at least one of the outer wall and the inner wall of the cylinder 1. Specifically, the reinforcing sheet 2 may be welded to the outer wall of the cylinder 1 or may be welded to the inner wall of the cylinder 1. In other embodiments, the reinforcing sheet 2 may be welded and fixed on the inner wall and the outer wall of the cylinder 1 at the same time, so that the reinforcing sheet 2 is more flexible to use, and is also beneficial to further improving the connection strength between the air inlet pipe 3 and the welding position of the cylinder 1.
In some embodiments, the reinforcing sheet 2 is in close proximity to at least one of the outer wall and the inner wall of the barrel 1. When the cross section of the cylinder 1 is circular, as shown in fig. 6, the central angle corresponding to the jack setting area 7 is alpha, at this time, the reinforcing sheet 2 is attached to the outer wall of the cylinder 1, and the curvature of the inner side surface of the reinforcing sheet 2 is the same as that of the jack setting area 7, so that when the reinforcing sheet 2 is fixed to the outer wall of the cylinder 1, the inner side surface of the reinforcing sheet 2 is fully attached to the outer wall of the cylinder 1, which is beneficial to enhancing the fixing effect of the reinforcing sheet 2 and the cylinder 1 and enhancing the tightness between the reinforcing sheet 2 and the cylinder 1.
In other embodiments, when the reinforcing sheet 2 is fixed to the inner wall of the cylinder 1, the curvature of the outer surface of the reinforcing sheet 2 matches the curvature of the inner wall corresponding to the insertion hole arrangement region 7 of the cylinder 1. It will be appreciated that in other embodiments, the barrel 1 may be prismatic, in which case the inner or outer sides of the reinforcing sheet 2 may be planar.
In some embodiments, the reinforcing sheet 2 is rectangular, circular, oval or square. Specifically, as shown in fig. 8, the reinforcing sheet 2 may be a circular plate, and as shown in fig. 9, the reinforcing sheet 2 may be a rectangular plate. In other embodiments, the reinforcing sheet 2 may be an elliptical plate, a square plate, a triangular plate, a polygonal plate, a irregular plate, or the like, and the shape of the reinforcing sheet may be selected according to practical situations.
Preferably, as shown in fig. 7, the reinforcing plate is in the shape of a rounded rectangle.
In some embodiments, the minimum spacing between the peripheral profile of the reinforcing sheet 2 and the peripheral profile of the air inlet pipe socket 6 is greater than the greater of the thickness of the reinforcing sheet 2 and the wall thickness of the barrel 1.
Specifically, as shown in fig. 7, the outer peripheral contour of the intake pipe insertion hole 6 is located within the outer peripheral contour of the reinforcing sheet 2, with a minimum spacing L between the outer peripheral contour of the reinforcing sheet 2 and the outer peripheral contour of the intake pipe insertion hole 6 in any radial direction along the intake pipe insertion hole 6, the minimum spacing L being larger than the thickness of the reinforcing sheet 2, and the minimum spacing L being also larger than the wall thickness of the cylinder 1. Thereby, the reinforcing sheet 2 can be prevented from being welded through in the radial direction along the intake pipe insertion hole 6.
Preferably, the minimum distance L is 1 to 5 millimeters. Specifically, the minimum pitch L may be any value between 1 mm and 5mm, for example, the minimum pitch L may be 1 mm, 2 mm, 3 mm, 4 mm, 5mm, or the like.
In some embodiments, the material of the reinforcing sheet 2 is the same as the material of the cylinder 1. For example, the reinforcing sheet 2 and the cylinder 1 may be made of carbon steel, stainless steel, copper, etc., so that tunnel furnace brazing is facilitated. It will be appreciated that in other embodiments, the materials of the reinforcing sheet 2 and the cylinder 1 may be different, for example, the reinforcing sheet 2 may be carbon steel, the cylinder 1 may be copper, etc.
In some embodiments, the peripheral contour of the reinforcing sheet 2 coincides with the peripheral contour of the jack placement area 7. As shown in fig. 1, the outer peripheral contour of the reinforcing sheet 2 is the same as the outer peripheral contour of the insertion hole arrangement region 7 in size and shape, and the outer peripheral contour of the reinforcing sheet 2 and the outer peripheral contour of the insertion hole arrangement region 7 completely coincide when the reinforcing sheet 2 is installed in the insertion hole arrangement region 7. In other embodiments, as shown in fig. 7, the peripheral contour of the reinforcing sheet 2 may be located inside the peripheral contour of the jack placement 7, in which case at least part of the peripheral contour of the reinforcing sheet 2 may coincide with the peripheral contour of the jack placement 7.
In some embodiments, as shown in fig. 5, at least a portion of the air inlet tube 3 extends out of the air inlet tube insertion hole 6 and into the inner cavity of the barrel 1. Therefore, the structural strength of the installation of the air inlet pipe 3 can be ensured, and the sealing performance of the installation of the air inlet pipe 3 can be enhanced.
In some embodiments, the oil separator further comprises an air outlet pipe 4 and an oil return pipe 5, wherein the air outlet pipe 4 is arranged at the top of the cylinder 1 and is communicated with the inner cavity of the cylinder 1, and the oil return pipe 5 is arranged at the bottom of the cylinder 1 and is communicated with the inner cavity of the cylinder 1.
