Description

Technical Field

[0001] The invention relates to the field of oil-gas separators, in particular to an oil-gas separator fine separation unit with a bypass function. Background Art

[0002] The oil-gas separator is an important component to maintain the normal working environment of the engine and ensure the life and efficiency of the engine. With the continuous advancement of engine technology, the working conditions of the engine are becoming more and more intense, and the oil vapor caused by the crankcase ventilation system invades the intake system, making engine carbon deposition a common problem. The oil-gas separator is designed to solve this kind of problem. It can effectively prevent oil vapor from entering the intake system, ensuring that the throttle, intake manifold, intake duct and intake valve are kept clean and oil-free, thereby significantly reducing or even avoiding the formation of carbon deposits inside the intake system, which is crucial to improving engine efficiency and extending service life.

[0003] In the prior art, when the oil-gas separator processes the oil-gas mixture discharged from the crankcase, foreign matter may accumulate due to oil solidification, impurity deposition, etc. This may block the oil return or gas circulation path and affect the normal operation of the engine. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an oil-gas separator fine separation unit with a bypass function in view of the current status of the prior art.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: to propose an oil-gas separator fine separation unit with bypass function, comprising:

[0006] First template;

[0007] A second template, which is clamped with the first template and whose side wall and the first template form a chamber, and a ring-shaped hollow portion is provided on a side of the second template away from the first template for allowing the oil-gas mixture to enter the chamber;

[0008] a separation element, which is arranged in the chamber and is used to separate the incoming oil-gas mixture;

[0009] A guide channel, located at the junction of the first template and the second template, for guiding out the gas separated by the separation element;

[0010] The second template can move relative to the first template due to the blockage of the separation piece, and the side wall of the second template is separated from the first template to form a bypass channel for the gas to flow out of the chamber.

[0011] The above-mentioned oil-gas separator fine separation unit with bypass function also includes a fixing rod, and the second template is provided with a through hole, one end of the fixing rod is fixed on the first template and the other end passes through the through hole and is inserted into the second template.

[0012] In the above-mentioned oil-gas separator fine separation unit with bypass function, an elastic member is sleeved on the fixed rod, one end of the elastic member extends into the chamber through the through hole and is close to the inner edge of the through hole, so as to provide elastic support for the second template in the direction of the fixed rod.

[0013] In the above-mentioned oil-gas separator fine separation unit with bypass function, clamping grooves are provided on both sides of the first template, and clamping parts are provided on both side walls of the second template. The width of the clamping groove is greater than the width of the clamping part. The clamping parts on both sides are respectively movably clamped in the clamping grooves on both sides, so as to form the guide channel while the second template is clamped on the first template.

[0014] In the above-mentioned oil-gas separator fine separation unit with bypass function, the part of the clamping part on each side inserted into the clamping groove extends in the direction away from the first template, and the clamping part can move along the clamping groove due to the movement of the second template relative to the first template.

[0015] In the above-mentioned oil-gas separator fine separation unit with bypass function, an undercut structure is provided at the extended end of the clamping portion to prevent the clamping portion from being disengaged from the clamping groove.

[0016] Compared with the prior art, the advantage of the present invention is that a chamber is formed by clamping the first template and the second template, and the clamping point has a guide channel, a separator is arranged in the chamber, and an annular hollow portion is arranged on the second template. During normal operation, the oil-gas mixture enters the chamber through the annular hollow portion, and the separator arranged in the chamber immediately separates the mixture, so that the engine oil and the gas are separated, and the gas is discharged out of the chamber through the guide channel. If the separator is blocked due to factors such as engine oil solidification and impurity deposition, this process will be hindered. At this time, although the oil-gas mixture can still enter the chamber through the annular hollow portion, the normal discharge path of the gas is blocked, resulting in an increase in the air pressure in the chamber. The increased air pressure causes the second template to displace relative to the first template, and the gap between its side and the first template constitutes a bypass channel, and the gas is smoothly discharged from the chamber through this bypass path, thereby preventing excessive pressure accumulation in the chamber and protecting the engine from damage, thereby ensuring its continuous and stable operation.

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0023] like Figures 1 to 4 As shown, an oil-gas separator fine separation unit with bypass function of the present invention comprises:

[0024] A first template 1; a second template 2, which is clamped with the first template 1 and the side wall thereof forms a chamber with the first template 1, and a ring-shaped hollow portion 3 is provided on the side of the second template 2 away from the first template 1 for supplying the oil-gas mixture into the chamber; a separator 4 is provided in the chamber for separating the incoming oil-gas mixture; a guide channel 5, which is located at the clamping position of the first template 1 and the second template 2 and is used for guiding out the gas separated by the separator 4; the second template 2 can move relative to the first template 1 due to the blockage of the separator 4, and its side wall is separated from the first template 1 to form a bypass channel for supplying the gas to flow out of the chamber.

[0025] During normal operation of the oil-gas separator fine separation unit in the present scheme, the oil-gas mixture enters the chamber through the annular hollow portion 3, and the separator 4 arranged in the chamber immediately separates the mixture, so that the engine oil and the gas are separated, and the gas is discharged out of the chamber through the guide channel 5. However, if the separator 4 is blocked due to factors such as oil solidification and impurity deposition, this process will be hindered. At this time, although the oil-gas mixture can still enter the chamber through the annular hollow portion 3, the normal discharge path of the gas is blocked, resulting in an increase in the air pressure in the chamber. The increased air pressure causes the second template 2 to shift relative to the first template 1, and the gap between its side and the first template 1 constitutes a bypass channel, and the gas is smoothly discharged from the chamber through this bypass path, thereby preventing excessive pressure accumulation in the chamber and protecting the engine from damage, ensuring its continuous and stable operation, wherein the separator 4 is preferably fiber cotton.

[0026] In order to provide support and positioning for the second template 2, a fixing rod 6 is also included. A through hole 7 is provided on the second template 2. One end of the fixing rod 6 is fixed on the first template 1 by interference fit, and the other end passes through the through hole 7 and is inserted into the second template 2. When an abnormality occurs during the oil and gas separation process, such as blockage of the separation member 4 causing the air pressure in the chamber to increase, the second template 2 will move along the fixing rod 6 due to the thrust of the air pressure. This movement causes the side wall of the second template 2 to separate from the first template 1, and the gap between the two forms a bypass channel.

[0027] Furthermore, an elastic member 8 is sleeved on the fixing rod 6, and one end of the elastic member 8 extends into the chamber through the perforation 7 and is close to the inner edge of the perforation 7. The elastic member 8 limits the possible excessive movement between the fixing rod 6 and the second template 2, maintains a relatively stable connection between the two, and provides elastic support for the second template 2 in the direction of the fixing rod 6, which means that when there is no abnormal air pressure, the second template 2 will remain in place under the action of the elastic member 8. When blockage occurs during the oil and gas separation process, causing the air pressure to rise, the second template 2 can move along the fixing rod 6 under the push of the increased air pressure and form a bypass channel between the second template 1. The elastic member 8 is preferably a spring.

[0028] In order to allow the first template 1 to be movably connected to the second template 2, connecting grooves 9 are provided on both sides of the first template 1, and connecting parts 10 are provided on the two side walls of the second template 2. The width of the connecting grooves 9 is greater than the width of the connecting part 10. When the connecting part 10 of the second template 2 is embedded in the connecting groove 9 of the first template 1, not only the physical connection between the templates is realized, but also one or more spaces are defined. These spaces serve as the flow path of the gas separated from the oil and gas mixture, that is, the guide channel 5 is formed. The connecting structure is not only used to fix the components, but also cleverly integrates the construction of the fluid channel, thereby optimizing the compactness and functionality of the overall design.

[0029] Furthermore, the portion of the clamping portion 10 on each side inserted into the clamping groove 9 extends in a direction away from the first template 1, ensuring that when the air pressure in the chamber increases abnormally and generates thrust on the second template 2, the clamping portion 10 can slide smoothly and directionally along the clamping groove 9. This ingenious design not only promotes the directional displacement of the second template 2 in response to changes in air pressure, but also ensures the stability of the movement process and the continuity of the system function.

[0030] Furthermore, an undercut structure 11 is provided at the extended end of the clamping portion 10 , which is used to prevent the clamping portion 10 from excessively moving out of the clamping slot 9 when the clamping portion 10 slides along the clamping slot 9 .

[0031] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0032] In addition, in the present invention, descriptions such as "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0033] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0035] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways without departing from the scope defined by the spirit of the present invention.
