Description

Technical Field

[0001] The utility model relates to the technical field of racing cars, in particular to an oil-gas separator of lubricating oil for racing cars. Background Art

[0002] The engine is the soul of a racing car. When the engine is operating normally, due to the clearance between the piston ring and the cylinder bore, the burned gas will flow into the crankcase due to the pressure difference, and form an oil-gas mixture with the splashing oil droplets in the crankcase. The oil-gas separator installed in the engine assembly can separate the oil droplets and the gas. The separated oil droplets converge and flow back to the oil pan, and the separated gas returns to the combustion chamber to participate in the combustion.

[0003] When the existing oil-gas separator is used, it usually only separates the oil and gas through the filter element inside it, lacks pre-treatment and finishing treatment, and the oil-gas separation effect still has room for improvement. In addition, if a single filter element is used for separation, the service life of the filter element will also be short. Therefore, an oil-gas separator for racing lubricating oil is proposed.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figures 1 to 4As shown, in this embodiment, an oil-gas separator for lubricating oil for racing cars includes a shell 1, a positioning plate 12 is arranged inside the shell 1, the positioning plate 12 divides the inside of the shell 1 into a filter bin 11 and a tail bin 13, a filter element 8 is slidably inserted in the filter bin 11, a plurality of filter plates 14 are arranged in the tail bin 13, a sealing cover 3 is arranged at the front opening position of the shell 1, an air inlet 4 is arranged on the side wall of the sealing cover 3, a connecting hole 16 connecting the air inlet 4 and the filter bin 11 is opened at the center of the end of the sealing cover 3 close to the shell 1, an air outlet 5 connected to the tail bin 13 is arranged on the upper side of the rear end of the shell 1, and a discharge mechanism for oil is arranged at the bottom of the shell 1.

[0021] The oil and gas will enter the filter chamber 11 through the air inlet 4 and the connecting hole 16. When the oil and gas pass through the bend at the connection position of the air inlet 4 and the connecting hole 16, a violent collision will occur, thereby realizing the rough separation of the oil and liquid. After the oil and gas enter the filter chamber 11, they will be finely separated by the filter element 8, so that the oil and liquid are adsorbed by the filter element 8, and the airflow will float toward the tailing chamber 13. The filter plate 14 arranged in the tailing chamber 13 can perform the final screening of the airflow after the fine separation to prevent part of the oil and liquid from floating toward the air outlet 5 with the airflow. After screening by the filter plate 14, the airflow will be discharged through the air outlet 5, thereby performing triple separation treatment on the oil and gas, which can effectively improve the separation effect of the oil and gas and can make the service life of the filter element 8 longer.

[0022] Among them, the discharge mechanism is composed of an oil collecting tank 6 and an oil pump 7. The oil collecting tank 6 is fixedly connected to the bottom of the shell 1. The upper end of the oil collecting tank 6 is connected with the filter tank 11 and the tail tank 13. The bottom of the inner cavity of the oil collecting tank 6 is provided with an oil outlet 15 extending to the outside of the oil collecting tank 6. The oil pump 7 is arranged at the bottom of the oil collecting tank 6 at the position of the oil outlet 15.

[0023] The oil filtered by the filter element 8 and the filter plate 14 will drip into the oil collecting chamber 6 , and then the oil pump 7 is started to pump out the oil in the oil collecting chamber 6 .

[0024] The end of the sealing cover 3 is fixedly connected to a positioning column 10 at the position of the connecting hole 16 , and the connecting hole 16 crosses the positioning column 10 . The front end of the filter element 8 is provided with a positioning hole 9 that slidably fits with the positioning column 10 .

[0025] With such arrangement, the cooperation between the positioning column 10 and the positioning hole 9 can make the filter element 8 more stable after installation.

[0026] The positioning plate 12 is an annular plate, and the outer ring side wall of the positioning plate 12 is fixedly connected to the inner wall of the housing 1 .

[0027] The positioning plate 12 is arranged in this way to position one end of the filter element 8, and the annular positioning plate 12 will not block the flow of airflow.

[0028] A plurality of connecting plates 2 are fixedly mounted on both sides of the bottom of the housing 1 , and fixing holes are provided on the connecting plates 2 .

[0029] The housing 1 can be fixedly installed by the cooperation of the fixing bolts and the fixing holes.

[0030] An annular groove for positioning the filter plate 14 is provided on the inner wall of the housing 1 .

[0031] The filter plate 14 can be positioned by the provided annular groove to prevent the filter plate 14 from being skewed in the closing chamber 13 .

[0032] The length of the filter chamber 11 is equal to the length of the filter element 8 .

[0033] Such an arrangement can ensure that after the sealing cover 3 is installed on the housing 1 , the sealing cover 3 and the positioning plate 12 can just clamp the two ends of the filter element 8 , thereby completing the fixing of the filter element 8 .

[0034] The utility model provides an oil-gas separator for lubricating oil for racing cars, and the specific working principle is as follows:

[0035] The oil and gas will enter the filter bin 11 through the air inlet 4 and the connecting hole 16. When the oil and gas pass through the bend at the connection position of the air inlet 4 and the connecting hole 16, a violent collision will occur, thereby realizing the rough separation of the oil and liquid. After the oil and gas enter the filter bin 11, they will be finely separated by the filter element 8, so that the oil and liquid are adsorbed by the filter element 8, and the airflow will float toward the tailing bin 13. The filter plate 14 arranged in the tailing bin 13 can perform the final screening of the airflow after fine separation to prevent part of the oil and liquid from floating toward the air outlet 5 with the airflow. After screening by the filter plate 14, the airflow will be discharged through the air outlet 5, thereby performing triple separation treatment on the oil and gas, which can effectively improve the oil and gas separation effect and extend the service life of the filter element 8. The oil filtered by the filter element 8 and the filter plate 14 will drip into the oil collecting bin 6, and then the oil pump 7 is started to extract the oil in the oil collecting bin 6.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
