Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of crankcases, and particularly relates to an explosion-proof crankcase breather. Background Technique
[0002] On medium- and low-speed diesel engines, in order to prevent excessive accumulation of oil and gas in the crankcase and avoid excessive increase in temperature and pressure in the crankcase, in addition to installing an explosion-proof valve, a breathing device is generally also provided in the crankcase.
[0003] Generally, the breathing device separates oil and gas by arranging baffles in the passage. The baffles are used to prevent oil splashing and block oil droplets back into the crankcase. The oil and gas are discharged along the passage. However, this structure can only collect most of the oil in the oil and gas, and a small amount of oil will still be discharged with the oil and gas, resulting in unnecessary oil consumption, and the oil and gas will pollute the air; while the breathing device with a filter type oil and gas separator in the traditional one is difficult to process and manufacture due to its complex structure, and is inconvenient to use, maintain and service. Moreover, some filters are too close to the crankcase, and oil is easily splashed onto the surface of the filter, resulting in oil accumulation and blocking the breathing device.

[0010] A further setting of the present utility model is that fixing plates are fixedly connected to both sides of the bottom shell, and round holes are opened on one side of the fixing plates.
[0011] By adopting the above technical solution, the setting of the round holes and the fixing plates can facilitate the installation and fixation of the device.

[0017] By adopting the above technical solution, the setting of the gasket plays a role in protecting the fixing plate.
[0018] A further setting of the present utility model is that the number of the threaded holes is two, and the two threaded holes are symmetrically arranged with respect to the midline of the bottom shell.
[0019] By adopting the above technical solution, the setting of multiple threaded holes makes the sealing performance between the top cover and the bottom shell stronger.
[0020] A further setting of the present utility model is that a cylinder is arranged inside the bottom shell, and leakage holes are opened on the surface of the cylinder.
[0021] By adopting the above technical solution, the setting of the cylinder and the leakage holes can filter the oil.
[0022] A further setting of the present utility model is that the shape of the leakage hole is circular, and a filter screen is arranged inside the leakage hole.
