Description
Technical Field
The invention relates to the technical field of compression equipment, in particular to a compressor exhaust structure and a compressor.
Background
In the oil content structure of the existing built-in oil content screw compressor, the refrigerant is discharged from the exhaust pipe and enters a cavity between the oil content filter screen and the oil content barrel. After the mixture of the refrigerant and the oil is filtered by the oil filter screen, the gas is discharged out of the compressor through the exhaust port of the compressor, and oil drops filtered by the filter screen are deposited at the bottom and then flow back to the oil groove.
In the exhaust structure of the compressor, the exhaust pipe is directly and horizontally arranged, oil gas is separated only when passing through the filter screen, and only one-time separation effect is achieved; meanwhile, the exhaust port of the exhaust pipe is close to the lower oil groove, and a large amount of gas can pass through the lower part of the filter screen; the filtered refrigerant gas passing through the lower part is sucked into the oil drops in the bottom oil groove to be mixed together, so that the refrigerant discharged from the exhaust port of the compressor is mixed with more oil drops.
Meanwhile, in the compression process, the compression cavity is periodically communicated with the exhaust cavity, so that fluid discharged from the exhaust port is subjected to periodic pressure pulsation, and larger fluid noise is generated. In the structure, the exhaust port is directly connected with the exhaust cavity, and noise can be directly transmitted into the exhaust cavity, so that larger noise is formed.
Disclosure of Invention
The embodiment of the invention provides a compressor exhaust structure and a compressor, which can prevent refrigerant gas exhausted by an exhaust pipe from rolling oil drops at the bottom of a mat and improve oil efficiency.
In order to achieve the above object, an embodiment of the present invention provides a compressor exhaust structure, including an oil filter screen, an oil barrel, and an exhaust pipe, wherein the exhaust pipe extends into a cavity formed by the oil filter screen and the oil barrel, and the exhaust pipe is bent upward in the cavity.
Preferably, the exhaust port of the exhaust pipe is directed toward the side wall or the bottom wall of the oil tank.
Preferably, the outlet end face of the exhaust pipe is an inclined surface.
Preferably, the inclined surface faces a connection position of the bottom and the side wall of the oil tank.
Preferably, the exhaust pipe extends to a top side wall of the oil tank.
Preferably, a muffler is provided at the elbow front end of the exhaust pipe.
Preferably, the muffler is provided in the oil filter.
Preferably, the bending angle of the exhaust pipe is 90 °.
Preferably, the barrel bottom and the side wall are in arc transition connection.
According to another aspect of the present invention, there is provided a compressor including a discharge structure, which is the compressor discharge structure described above.
By applying the technical scheme of the invention, the compressor exhaust structure comprises the oil filter screen, the oil barrel and the exhaust pipe, wherein the exhaust pipe extends into a cavity formed by the oil filter screen and the oil barrel, and the exhaust pipe is bent upwards in the cavity. Because the exhaust pipe is bent upwards in the cavity, the exhaust port of the exhaust pipe can be far away from the bottom oil groove, so that refrigerant gas exhausted by the exhaust pipe is prevented from rolling bottom oil drops, and the oil content efficiency is improved.
Drawings
Fig. 1 is a schematic structural view of a compressor discharge structure according to an embodiment of the present invention.
Reference numerals illustrate: 1. an oil filter screen; 2. an oil content barrel; 3. an exhaust pipe; 4. a muffler; 5. an oil groove; 6. and a compressor discharge port.
Detailed Description
The invention will now be described in further detail with reference to the drawings and specific examples, which are not intended to limit the invention thereto.
Referring to fig. 1 in combination, according to an embodiment of the present invention, a compressor discharge structure includes an oil filter screen 1, an oil tank 2, and a discharge pipe 3, the discharge pipe 3 extending into a cavity formed by the oil filter screen 1 and the oil tank 2, the discharge pipe 3 being bent upward in the cavity.
Because the exhaust pipe 3 is bent upwards in the cavity, the exhaust port of the exhaust pipe 3 can be far away from the bottom oil groove 5, so that refrigerant gas discharged by the exhaust pipe 3 is prevented from rolling bottom oil drops, and the oil content efficiency is improved.
Preferably, the exhaust port of the exhaust pipe 3 faces the side wall or the bottom wall of the oil content barrel 2, so that the oil-gas mixture can be guided to the top or the upper side to be sprayed out, the gas is directly flushed out of the side wall or the barrel bottom of the top of the oil content barrel 2 after being sprayed out, the movement direction of the gas is changed sharply by impact, and any direction change movement can be regarded as local rotation movement. Due to the difference in gas and oil droplet density, separation occurs during rotation. The separated liquid and gas are downward due to density difference, the gas is upward, the gas is discharged through the upper filter screen to perform secondary oil-gas separation, and oil drops are deposited at the bottom and then flow into the oil groove 5 through the filter screen. The adoption of the structure is equivalent to adding one oil-liquid separation process in the exhaust stage, thereby improving the oil content efficiency.
The outlet end face of the exhaust pipe 3 is an inclined plane, so that the outlet section of the exhaust pipe 3 is increased, a larger airflow injection surface is formed, the contact area of oil-gas separation can be further improved, and the oil-gas separation efficiency is improved.
Preferably, the inclined surface is directed to the connection position of the bottom and the side wall of the oil content tank 2, and because the position is a bending position, a more intense swirling effect can be formed, so that the separation effect of the gas and the oil drops is better, and particularly, the separation effect is higher.
In this embodiment, the exhaust pipe 3 extends to the top side wall of the oil content barrel 2, so that after being discharged from the exhaust port of the exhaust pipe 3, the oil-gas mixture can directly impact the top side wall of the oil content barrel 2, so that oil drops can fall onto the bottom side wall of the oil content barrel 2 under the action of gravity after being separated, and gas refrigerant can be directly discharged from the exhaust port 6 of the compressor after being secondarily separated from the top through the oil content filter screen 1, thereby more effectively avoiding the gas refrigerant from contacting with the oil drops again after the oil-gas separation, and improving the oil-gas separation effect.
The muffler 4 is arranged at the front end of the elbow of the exhaust pipe 3, so that exhaust noise of the compressor can be effectively reduced.
The muffler 4 is arranged in the oil filter screen 1 in a penetrating way, so that the muffler 4 is more stably fixed through the oil filter screen 1, vibration cannot occur, the installation fixing effect of the muffler 4 is improved, and the silencing performance of the muffler 4 is improved.
The bending angle of the exhaust pipe 3 is, for example, 90 °.
The arc transitional connection between the barrel bottom and the side wall can enable the movement direction of the oil-gas mixture impacted at the arc position to change more drastically, and the oil-gas separation effect is more thorough.
According to an embodiment of the present invention, a compressor includes a discharge structure, which is the compressor discharge structure described above.
Of course, the above is a preferred embodiment of the present invention. It should be noted that it will be apparent to those skilled in the art that several modifications and adaptations can be made without departing from the general principles of the present invention, and such modifications and adaptations are intended to be comprehended within the scope of the present invention.
