AI Technical Summary
During the ship's navigation, the high-temperature and high-concentration oil and gas mixture discharged from the crankcase ventilation pipe of the main engine partially condenses into liquid when the external temperature drops, which may fall back into the main engine, causing harm.
A main machine crankcase ventilation pipe discharge cover device is designed, including the discharge cover body, the lower blocking plate, the upper blocking plate, the air intake short tube, the air outlet short tube and the drain short tube. Through the staggered air outlet and air intake short tubes, the condensed liquid is prevented from flowing back, and the condensed liquid is discharged to other special compartments through the drain short tubes.
It effectively prevents the condensate liquid from falling back into the main machine, protects the equipment, and has a simple structure, low cost and convenient maintenance, and is suitable for all kinds of ships.

Abstract
Description
Technical Field
[0001] The invention relates to a main engine crankcase air vent pipe discharge cover device. Background Art
[0002] When the ship is sailing, the crankshaft of the main engine rotates at high speed, and a high-temperature and high-concentration oil-gas mixture is generated in the engine. When it is discharged through the crankcase breather pipe, it will partially condense into liquid as the external temperature drops. In order to prevent the condensed liquid in the pipe from falling back into the main engine and causing damage to the equipment, a discharge hood device needs to be installed between the main engine crankcase and the breather pipe. Summary of the invention
[0003] The object of the present invention is to provide a main engine crankcase vent pipe discharge cover device.
[0004] The technical solution adopted by the present invention to achieve the above-mentioned purpose is: a main engine crankcase air vent exhaust cover device, comprising an exhaust cover body (1), an exhaust cover lower plugging plate (2), an exhaust cover upper plugging plate (3), an intake short pipe (4), an exhaust short pipe (5) and a discharge short pipe (6), wherein the exhaust cover upper plugging plate (3) and the exhaust cover lower plugging plate (2) are respectively installed at the upper and lower ends of the exhaust cover body (1), the intake short pipe (4) and the discharge short pipe (6) are respectively connected to the lower end of the exhaust cover body (1), the exhaust short pipe (5) is connected to the upper end of the exhaust cover body (1), and the exhaust short pipe (5) and the intake short pipe (4) are alternately arranged at the upper and lower ends of the exhaust cover body (1).
[0005] An inlet flange (7) is mounted on the air intake short pipe (4).
[0006] An outlet flange (8) is installed on the outlet short pipe (5).
[0007] A discharge flange (9) is installed on the discharge short pipe (6).
[0008] The main engine crankcase vent pipe discharge cover device of the present invention has a simple structure, is easy to manufacture, has a low cost, is simple to maintain, is easy to install, can be applied to various types of ships, and achieves a good use effect. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 The present invention is a schematic structural diagram of a main engine crankcase vent pipe discharge cover device.

[0011] like Figure 1As shown, the main engine crankcase vent pipe exhaust cover device includes an exhaust cover body 1, an exhaust cover lower plugging plate 2, an exhaust cover upper plugging plate 3, an intake short pipe 4, an exhaust short pipe 5, a discharge short pipe 6, an inlet flange 7, an outlet flange 8 and a discharge flange 9. The exhaust cover upper plugging plate 3 and the exhaust cover lower plugging plate 2 are respectively installed at the upper and lower ends of the exhaust cover body 1, the intake short pipe 4 and the discharge short pipe 6 are respectively connected to the lower end of the exhaust cover body 1, the exhaust short pipe 5 is connected to the upper end of the exhaust cover body 1, the exhaust short pipe 5 and the intake short pipe 4 are alternately arranged at the upper and lower ends of the exhaust cover body 1, and the inlet flange 7 is installed on the intake short pipe 4. The outlet flange 8 is installed on the air outlet short pipe 5, and the discharge flange 9 is installed on the discharge short pipe 6. The main engine crankcase vent pipe discharge cover device is air-intaked through the lower end and exhausts through the upper end. The lower air intake short pipe extends into the main body by 100mm, and the air intake short pipe and the air outlet short pipe are staggered to prevent the condensed liquid from flowing back. A discharge short pipe is arranged at the lower right end of the discharge cover body to discharge the condensed liquid to other special compartments through the discharge short pipe. The main engine crankcase vent pipe discharge cover device of the present invention has a simple structure, is easy to manufacture, has low cost, is simple to maintain, is easy to install, and can be applied to various types of ships to achieve a good use effect.
