Detailed Description
The present invention will be more fully described in the following detailed description of the preferred embodiments thereof, taken together with the accompanying drawings.
As shown in fig. 1, 2 and 3, an oil mist preventing tank comprises a tank body 10, which is surrounded by a top plate 11, a bottom plate 12 arranged below the top plate, and a plurality of side wall plates fixedly arranged between the top plate and the bottom plate; one side wall plate 13 is provided with a ventilation port 14; the oil gas outlet of the oil cabin vent pipe is arranged in the box body 10. A blind window 15 is arranged in the ventilation opening 14.
An upper condensing plate 31 and a lower condensing plate 32 are sequentially arranged between the oil tank vent pipe 20 and the vent port 14 in the tank body; the top of the upper condensation plate 31 is fixedly connected with the top plate 11; the bottom of the lower cold plate 32 is secured to the bottom plate 12.
And passages for oil gas discharged by the oil tank vent pipes to circulate are arranged between the oil tank vent pipes 20 and the upper condensation plate 31, between the bottom of the upper condensation plate 31 and the bottom plate 12, between the upper condensation plate 31 and the lower condensation plate 32, between the top of the lower condensation plate 32 and the top plate 11, and between the lower condensation plate 32 and the vent holes 14 in the box body.
The upper and lower condensing plates may have various shapes. Go up the condensing panel and can be straight board with lower condensing panel, go up the condensing panel and can equal channel plate with lower condensing panel, or, go up one in condensing panel and the lower condensing panel and be straight board, another is the channel plate.
In this embodiment, the upper condensation plate 31 and the lower condensation plate 32 are both trough plates having a plurality of grooves, and the grooves on the upper condensation plate and the grooves on the lower condensation plate are both vertically distributed.
The top plate 11 is provided with a cleaning cover 41 which can clean the inside of the box body after being opened, and the cleaning cover 41 is detachably connected with the top plate 11. Preferably, the cleaning cover and the top plate are in threaded connection.
