Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to an integrated air compressor host oil and gas multiple separation structure. Background Art

[0002] An air compressor, or air compressor in short, is a device that compresses air or other gases to high pressure to meet various industrial and daily needs. Its working principle mainly involves three processes: intake, compression, and exhaust.

[0003] like Figure 1 As shown, the oil-gas separation structure of the conventional air compressor includes a first pipe section 10.1, a second pipe section 10.2, an oil-gas separation pipe section 10.3, and a gas pipe section 10.4. The oil-gas mixture at the bottom of the oil drum 7.2 passes through the first pipe section 10.1 and the second pipe section 10.2 and enters the oil-gas separation pipe section 10.3. After preliminary separation in the oil-gas separation pipe section 10.3, the oil-gas mixture is separated by a high-speed cyclone. Lubricating oil 15 drips from the lower end of the oil-gas separation pipe section 10.3 into the oil drum 7.2 under the action of gravity. The compressed air continues to flow upward, passes through the gas pipe section 10.4, and flows to the inlet end of the oil separation assembly 8. The oil-gas mixture is initially separated in the oil-gas separation pipe section 10.3. In this oil-gas separation structure, the oil-gas separation pipe section 10.3 is only located below the safety valve seat, and its separation stroke is short. After the initial separation, the oil content in the air is high, exceeding the separation capacity of the subsequent oil separation components, resulting in the oil content in the output compressed gas not meeting the standard. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in order to overcome the shortcomings of the prior art of short initial separation stroke and high oil content in the separated air, the utility model provides an integrated air compressor main engine oil and gas multiple separation structure.

[0005] The technical solution adopted by the present invention to solve its technical problems is: an integrated air compressor main engine oil and gas multiple separation structure, including a pump head and an oil barrel connected to each other, the oil barrel filled with lubricating oil, an oil separation component provided above the oil barrel, a first pipe section provided at the bottom of the oil barrel, a second pipe section provided on the side wall, and a cyclone separation sleeve provided on the top, the first pipe section is the main oil and gas pipe, and its left end is connected with the pump head, and the right end is connected with the lower end of the second pipe section, a cyclone channel is formed between the outer wall of the cyclone separation sleeve and the inner wall of the oil barrel, the upper end of the second pipe section is connected with the upper end of the cyclone channel, and the lower end of the cyclone channel is connected with the space inside the oil barrel above the lubricating oil liquid level; at least one partition is also provided on the pump head inside the oil barrel along the air flow direction, and the air inlet of the oil separation component is arranged downstream of the air flow of the last partition.

[0006] The second pipe section is arranged along the wall of the oil barrel, which can guide the oil-gas mixture while dissipating heat through the oil barrel wall; the cyclone separation structure is designed as a cyclone separation sleeve, which simplifies the structure, increases the outer diameter of the cyclone separation sleeve, and extends the separation stroke of oil and gas in the cyclone channel.

[0007] Furthermore, the oil separator assembly includes an oil separator core, an oil separator core shell and a spring. The oil separator core is arranged inside the oil separator core shell, and the bottom is installed on the oil separator seat. The oil separator seat is arranged on the oil barrel. The spring is arranged between the top of the oil separator core and the oil separator core shell to press the oil separator core against the end face of the oil separator seat.

[0008] The oil separator component adds a metal spring between the oil separator core and its shell. On the one hand, the metal spring can conduct electricity and discharge the static electricity generated inside the oil separator core. On the other hand, it can also play a compression sealing and buffering role, firmly fitting the oil separator core to the end face of the oil separator seat.

[0009] Further preferably, there are two partitions, namely a first partition and a second partition, and the first partition and the second partition are arranged in sequence along the airflow direction.

[0010] Furthermore, a plurality of first air holes are provided on the first partition plate, the inner circle of the first partition plate matches the outer shape of the pump head at the installation position, and the outer circle is semicircular.

[0013] Furthermore, a temperature sensor is provided at the connection between the first pipe section and the second pipe section for monitoring the temperature of the lubricating oil in the oil barrel, and when the temperature exceeds a limit, a frequency conversion controller is used to start a cooling fan.

[0014] Furthermore, a valve seat is provided on the oil barrel above the cyclone separation sleeve, and a safety valve is installed in the valve seat. The main function of the safety valve is to prevent the compressed air inside the barrel from being too high and to unload the protective function when the pressure exceeds a certain level.

[0015] The beneficial effects of the present invention are as follows: the present invention provides an integrated air compressor main engine oil and gas multiple separation structure, which changes the flow direction, increases the stroke of separated air, separates oil and gas multiple times through cyclone channels, partitions, etc., and achieves better oil and gas separation effect.

The oil barrel 7.2 is equipped with a first pipe section 10.1 at the bottom, a second pipe section 10.2 on the side, and a cyclone separation sleeve 3 at the top. The first pipe section 10.1 serves as the main oil and gas pipe, connecting to the pump head 7.1 at its left end and the lower end of the second pipe section 10.2 at its right end. A cyclone passage 4 is formed between the outer wall of the cyclone separation sleeve 3 and the inner wall of the oil barrel 7.2. The upper end of the second pipe section 10.2 connects to the upper end of the cyclone passage 4, while the lower end of the cyclone passage 4 connects to the interior of the oil barrel 7.2 above the level of the lubricating oil 15. A temperature sensor 7.5 is installed at the junction of the first and second pipe sections 10.1 and 10.2. This sensor monitors the temperature of the lubricating oil 15 in the oil barrel 7.2 and activates a cooling fan via a frequency converter when the temperature exceeds a specified limit. A valve seat is installed on the oil barrel 7.2 above the cyclone separation sleeve 3, housing a safety valve 7.4. The main function of the safety valve 7.4 is to prevent the compressed air inside the barrel from being too high and to unload the air when it exceeds a certain pressure. At least one partition is also provided on the pump head 7.1 inside the oil barrel 7.2 along the airflow direction, and the air inlet 5 of the oil separation component 8 is provided downstream of the last partition. In this embodiment, there are two partitions, namely the first partition 1 and the second partition 2, which are arranged in sequence along the airflow direction. Figure 3 and Figure 4 As shown, the first partition plate 1 is provided with a plurality of first air holes 1.1. The inner ring 1.2 of the first partition plate 1 matches the shape of the pump head 7.1 in its installed position, and the outer ring 1.3 is semicircular.

They are distributed on the first and second partition plates 1 and 2 above the lubricating oil inside the oil drum.

[0026] Working principle:

[0027] like Figure 5As shown in the figure, "○" represents lubricating oil 15, "□" represents compressed air, and the arrow represents the direction of airflow. The inhaled air is pressurized by the pump head 7.1 to form a pressurized oil-gas mixture, which enters the oil barrel 7.2. The oil-gas mixture at the bottom of the oil barrel 7.2 passes through the first pipe section 10.1 and the second pipe section 10.2 and enters the cyclone channel 4 of the cyclone separation sleeve 3. The oil-gas mixture rotates at a high speed in the cyclone channel 4, so that the oil and gas are separated for the first time. The separated oil falls into the lubricating oil 15 in the oil barrel 7.2 under the action of gravity. Since the surface of the lubricating oil 15 is filled with high-pressure gas, the compressed air flows toward the oil separation component 8 under pressure, and is separated multiple times by multiple layers of partitions to further separate the oil in the oil and gas. After passing through the partition, it enters the oil separation component 8 for subdivision and finally flows out from the air outlet 6 of the oil separation component 8.

[0028] Compared with the original structure, the separation stroke is greatly extended, making the separation effect better.

[0029] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the scope of the present invention. The technical scope of this utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
