Description

Technical Field

[0001] The utility model relates to the field of automobile internal combustion engines, in particular to a high-efficiency oil-gas separator device. Background Art

[0002] Internal combustion engines are the energy source for vehicle propulsion and conventional power generation. People hope to improve the overall operating efficiency of internal combustion engines through technological innovation and advanced manufacturing, and obtain more driving energy with less fuel. The crankcase, as the core component of the internal combustion engine, is the core of the entire internal combustion engine structure. The oil and gas mixed exhaust gas generated during the work process must be separated and filtered in a cycle. In order to improve the separation and filtration effect, conventional cycle collection and separation filters are generally used, or filter elements with smaller porosity are used for filtration. However, in this case, insufficient oil and gas separation and frequent filter element replacement will occur, resulting in adverse effects: additional oil consumption, carbon deposits in the cylinder of the internal combustion engine, resulting in high fuel consumption of the internal combustion engine, insufficient filtration leading to air pollution caused by oil and gas, and other adverse environmental problems.

[0003] Although conventional oil-gas separators currently use one-stage or two-stage circulation oil-gas separator devices, they generally have disadvantages such as large space occupation, relatively complex internal component structure, and high maintenance cost. Utility Model Content

[0007] Preferably, the main adsorption frame of the integrated separation filter element adopts an internal multi-ring cage structure, and the filter element fixed partition and the main body base adopt a fixed slot and are embedded and connected.

[0008] Preferably, the first filter plates are arranged in rectangular strips at intervals from each other, with a certain distance difference between them to facilitate oil condensation.

[0009] Preferably, the second filter screen is made of corrosion-resistant metal material, and the hole gap of the metal filter screen is between 1MM-0.3MM. This type of filter screen is a replaceable filter screen.

[0010] Preferably, the filter separation plates are arranged in a herringbone shape from top to bottom, and the separation filter plates are fixedly connected to the base on the upper part of the main body.

[0027] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0028] like Figure 1 、 Figure 2 As shown, the utility model is a high-efficiency oil-gas separator device, comprising: an upper cover 5, a main body 4, a main body base 1, and an integrated separation filter element 3, wherein the upper cover 5 and the main body 4 are connected by a rotational locking method. The upper portion of the main body 4 is provided with a mounting groove for the upper cover to be rotated and fixed.

[0029] like Figure 3As shown, the main base 1 is provided with: a mixed air inlet 101, an oil outlet 102, a one-way valve 2, and a spoiler adsorption grid 201. The mixed air inlet 101 is used to connect the oil-gas mixture from the crankcase, and the spoiler adsorption grid 201 is arranged and distributed in a circular shape. The left and right sides of the spoiler adsorption grid itself are designed with unequal lengths, which is conducive to the spiral rise and adsorption of the surrounding mixed air flow. Since the air pressure generated by the oil-gas mixture varies with the operating conditions inside the engine crankcase, the air pressure of the mixed gas is subject to dynamic changes. Therefore, after the oil-gas mixture enters the air inlet, the pressure of the mixed oil and gas changes constantly, and the density of the oil is greater than the density of oxygen. By utilizing the arrangement of the spoiler adsorption grid, the oil can be adsorbed and condensed on the spoiler adsorption grid to complete the initial oil-gas separation.

[0030] like Figure 5 , 6, 7, wherein: after the completion of the initial oil and gas separation, the relatively small diameter oil molecules and gas are mixed together, due to the impact of the air flow of the mixing inlet 101, Figure 5 It can be seen that the mixed gas reaches the first filter plate 405 inside the main body 2. It should be noted that the first filter plates are arranged in rectangular strips with a certain distance between them to facilitate the condensation and adsorption of oil. After the oil is adsorbed by the first filter plate, the unadsorbed oil and gas mixed molecules reach the integrated separation filter element 3 and are then Figure 5 and Figure 6 It can be seen that the integrated separation filter element is provided with a filter element fixing partition 301, a filter safety valve 302, a main body adsorption frame 303, and a spring limit block 306. The upper part of the filter element fixing partition 301 is connected to the upper fixed slot 404 inside the main body by a locking connection, and the lower part of the filter element fixing partition 301 is also connected to the upper slot of the main body base by a locking connection. The function of the slot is to fix the integrated filter element between the main body and the main body base, and to stabilize the structure during the adsorption of mixed gases under different working conditions. According to Figure 7As shown, the integrated filter element 3 is also equipped with a connecting rod spring 304 and a piston ring 305. When oil and gas molecules enter the integrated separation filter element, they are surrounded by airflow and circulate around the main adsorption frame 303. The main adsorption frame 303 absorbs a portion of the oil, completing the oil and gas separation and filtration. The absorbed oil condenses and flows into the one-way valve at the main base. Due to the uneven pressure of the external oil and gas mixture, when the engine is operating under high load (high speed, low speed), the unburned oil molecules will accumulate and increase in a short period of time. To cope with such extreme conditions or when the filter safety valve 302 becomes clogged due to excessive adsorption, the filter safety valve nozzle is subjected to the impact of high-speed air pressure (when conventional separation and filtration are no longer sufficient) and drives the spring connecting rod 304 and piston ring 305. Due to the raised structure of the piston ring 305, more oil and gas mixture molecules are pushed into the next level of separation and filtration, ensuring the maximum filtration efficiency of the integrated separation filter element. When the air pressure entering the mixed air inlet returns to below the maximum implementation efficiency of the integrated separation filter element, the connecting rod spring is affected by the pushing pressure of the mixed gas and the damping of the spring itself, and the connecting rod spring 304 will gradually return to its original position, which is the fixed end of the spring limit block 306.

[0031] After the oil and gas separation of the integrated separation filter element, in order to meet the needs of greater separation applications, the utility model sets a further step of precise separation. Figure 4 and Figure 5 It can be seen that after the separation of the integrated separation filter, the diameter of the oil molecules in the oil-gas mixture has become very small, and most of the oil molecules have been separated out. Therefore, in order to make the oil-gas separation more thorough, Figure 5 The filter hole 406 is affected by the airflow, and the small molecule oil and gas mixture enters through the filter hole 406. Figure 4As can be seen, a second filter 401 is positioned above the filter hole 406. The gaps between the filter screens are between 1mm and 0.3mm. Made of corrosion-resistant metal, the second filter retains its shape even under prolonged exposure to high temperatures. Driven by the rising airflow, the small oil-liquid mixture that passes through the second filter 406 reaches the filter separation plate 402. The filter separation plates 402 are arranged in a herringbone pattern with multiple intervals, allowing the mixed gas to repeatedly impact the filter separation plates 402. The filter separation plates 402 themselves possess a certain oil adsorption capacity, allowing the oil to condense and settle. After passing through the filter separation plates 402, a corresponding outlet 403 is connected to the main body for the separated and filtered gas to be discharged. The condensed oil adsorbed by the filter separation plates 402 is collected through the oil through-hole 407. The oil in the oil through-hole then flows into the oil outlet 102 and is introduced into the engine through the oil pipe, achieving oil-gas separation and efficient utilization of the oil and gas.

[0032] The overall structural design layout of the utility model is simple and exquisite, the overall device occupies a small volume, adopts multiple steps to separate oil and gas, is easy to install, and is convenient for implementation and promotion.
