The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
A novel vertical oil separator structure for a compressor according to an embodiment of the present invention, as shown in fig. 1 to 3, includes: the oil separator comprises an oil separator shell 5, wherein the top of the oil separator shell 5 is fixedly connected with a top cover 11, the middle part of the top cover 11 is provided with an oil separator exhaust outlet 1, and the inner wall surface of the oil separator shell 5 is coated with refrigeration oil; an oil reservoir 7 is formed in the inner bottom of the oil separator case 5.
Specifically, a starting point exhaust flow passage 2 is formed at the bottom of the outer wall of the oil separator shell 5, an end point exhaust flow passage 4 is formed at the top of the outer wall of the oil separator shell 5, the end point exhaust flow passage 4 is communicated with the inside of the oil separator shell 5, and the center line of the starting point exhaust flow passage 2 is parallel to the center line of the end point exhaust flow passage 4; the starting point exhaust runner 2 and the end point exhaust runner 4 are communicated through a middle section exhaust runner 3, and the middle section exhaust runner 3 is spiral, so that the longest exhaust runner is ensured, and the flow direction and the speed of airflow are ensured.
Furthermore, the end cut of the end exhaust flow passage 4 is tangent to the oil separator shell 5, and the exhaust airflow is tangent to the inner wall of the oil separator shell 5 and enters the oil separator due to inertia; meanwhile, the end notch of the end exhaust flow passage 4 changes the speed of the airflow; the structure guides the air flow to spirally move around the inner wall of the oil separator shell 5 according to the changed rotating speed; the air flow is cooled by the inner wall of the oil separator housing 5, and large particles of oil are separated as the flow velocity decreases and changes direction.
Further, a baffle 8 is arranged in the oil separator shell 5, and the baffle 8 is umbrella-shaped, so that the oil in the oil storage tank 7 is prevented from being taken away by evaporation of gas dissolved in the oil; the distance between the baffle plate 8 and the inner bottom of the oil separator shell 5 is 50-100 mm.
Further, a limiting block 12 for installing the baffle plate 8 is formed on the inner wall of the oil separator shell 5; in order to enable the baffle plate 8 to be stably mounted on the limiting block 12, a stud 13 is connected to the oil separator shell 5, the stud 13 penetrates through the baffle plate 8, and a nut 14 is connected to the stud 13 in a threaded mode to fix the baffle plate 8.
Furthermore, more than one casting process hole 9 is arranged on the middle section exhaust runner 3, and the casting process holes 9 are communicated with the middle section exhaust runner 3; the inner core of the middle section exhaust runner 3 is conveniently divided into a plurality of sections during casting, so that the internal cleaning of the middle section exhaust runner 3 during casting is facilitated; and a sealing cover 10 is connected to the casting process hole 9 and used for sealing the casting process hole 9.
Further, the bottom of the exhaust outlet 1 of the oil separator is connected with an exhaust guide plate 6, and the exhaust guide plate 6 is positioned in the oil separator shell 5; the exhaust guide plate 6 is in a circular tube shape, the bottom end of the exhaust guide plate 6 is lower than the end cut position of the end exhaust flow passage 4, and as a large amount of refrigeration oil is attached to the inner wall of the oil separator shell 5, and the airflow close to the inner wall of the oil separator shell 5 can contain a large amount of refrigeration oil, the exhaust guide plate 6 is arranged to separate the airflow on the side wall and only allow the completely separated airflow in the middle of the oil separator to pass through; meanwhile, in order to prevent the end cut-off airflow of the exhaust flow passage 4 from being exhausted along the exhaust outlet 1 of the oil separator at the first time when the airflow enters the compressor, the bottom end position of the exhaust guide plate 6 must be lower than the end cut-off position of the end exhaust flow passage 4.
The oil separator is vertically installed, when the oil separator works, the exhaust airflow with the refrigeration oil enters the starting exhaust flow passage 2 from the lower part of the oil separator and reaches the ending exhaust flow passage 4 positioned at the top end of the oil separator shell 5 along the spiral middle section exhaust flow passage 3; because the end exhaust flow passage 4 is tangent to the oil separator shell 5, the exhaust airflow can enter the oil separator in a tangent manner with the inner wall of the vertical oil separator and spirally move around the inner wall; in the process, because the inner wall of the oil separator cools the airflow and the speed of the airflow slowly decreases, large-particle oil can be separated by utilizing the difference of the weight of the gas and the oil mist and the inertia force.
When the centrifugal force is not enough to enable the airflow to spirally run along the inner wall of the oil separator, the oil and the gas are basically separated; the separated oil flows down to the oil storage tank 7 along the inner wall of the oil separator due to the weight, and the gas moves to the exhaust outlet 1 of the oil separator along the pressure difference and is discharged from the compressor at the exhaust outlet 1 of the oil separator after passing through the exhaust guide plate 6.
The terminal exhaust flow passage 4 and the oil separator exhaust outlet 1 are both positioned at the upper part of the oil separator shell 5, and the speed of the airflow just leaving the terminal exhaust flow passage 4 and entering the oil separator shell 5 is higher, so that the integral airflow flow velocity block at the upper part of the oil separator shell 5 is caused, and in addition, the air needs to be discharged from the upper part, so that the integral airflow at the upper part of the oil separator shell 5 is relatively disordered; in order to avoid the gas flow which has finished the oil-gas separation and the gas flow which has not finished the oil-gas separation from mixing together, and cause the gas flow which has finished the oil-gas separation to be discharged together with the gas which has not finished the oil-gas separation, an exhaust guide plate 6 is additionally arranged, and for this reason, the bottom end position of the exhaust guide plate 6 must be lower than the end cut position of the exhaust flow passage 4 at the end of the discharge.
In the oil storage tank 7, due to the existence of a small amount of refrigerant liquid, part of the oil may move to the exhaust outlet 1 of the oil separator with the refrigerant liquid during evaporation, so that an umbrella-shaped baffle 8 is additionally arranged, the airflow meets the umbrella-shaped baffle 8 upwards, the airflow moves along the inner wall of the baffle 8, finally, the air is exhausted upwards away from the umbrella-shaped baffle 8 at the outer ring of the inner wall of the baffle 8, and the oil drops continuously in each area of the inner wall of the baffle 8 due to the weight, so that the amount of the frozen oil in the oil storage tank 7 is ensured.
The spiral middle section exhaust runner 3 is long in length, the inner core of the spiral middle section exhaust runner is difficult to manufacture, and the inner runner of the spiral middle section exhaust runner is difficult to clean, so that one to a plurality of casting process holes 9 are needed to be added, the inner core of the runner part can be divided into multiple sections during casting, and casting and cleaning of the inside of the runner are facilitated.
The above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made in accordance with the claims of the present invention should be covered by the present invention.
