In the present embodiment, a circle of air release holes 111 is formed at the top of the hollow cylinder wall 110, so that the lubricant oil with a relatively high viscosity can smoothly drop downward, and oil mist volatilized from the lubricant oil with a relatively high temperature can be discharged out of the hollow cylinder wall 110 through the circle of air release holes 111, and collected below the top plate of the oil tank housing 10, and finally sucked away through the oil mist suction holes 35 and changed into liquid lubricant oil again by using an oil mist separator (not shown), and then falls into the third accommodating cavity 400 again.

The lower baffle 115 forms an upwardly curved free end 1151, and when the lubricating oil falls down on the hollow cylinder wall 110, the lower baffle 115 always holds a certain amount of lubricating oil (as shown in the black area 117 in fig. 8), and the free end 1141 of the upper baffle 114 is always submerged in the lubricating oil held by the lower baffle 115. The top of the hollow cylinder wall 110 has an opening 1119 to connect the first oil return pipe 4 or the second oil return pipe 42 or the third oil return pipe 11 through the opening 1119. The opening 1119 communicates with the first oil return pipe 4 or the second oil return pipe 42 or the third oil return pipe 11. Meanwhile, the diameter of the hollow cylinder wall 110 is matched with the diameter of the first oil return pipe 4, the second oil return pipe 42 or the third oil return pipe 11. In this embodiment, three sets of oil storage plates are disposed inside the hollow cylinder wall 110, so that the lubricating oil falling into the first accommodating cavity 200 is buffered, and the impact of the lubricating oil on the lubricating oil accommodated in the oil tank casing 10 during the process of falling back to the oil tank casing is further reduced.

Referring to FIG. 2, in this embodiment, the top of the first baffle 15 forms a first equalizing vent 152, the top of the second baffle 16 forms a second equalizing vent 162, and the first equalizing vent 152 is offset from the second equalizing vent 162. The first and second equalizing

vents

152, 162 are rectangular in shape, and the first and second equalizing

vents

152, 162 are flat. The oil tank housing 10 is rectangular, and the first accommodating cavity 200, the second accommodating cavity 300, and the third accommodating cavity 400 together form a hollow cavity, and lubricant is accommodated in the hollow cavity formed by the oil tank housing 10.

Referring to fig. 6, in the present embodiment, the first balance vent 152 and the second balance vent 162 are arranged in a staggered manner, which means that the first balance vent 152 and the second balance vent 162 are respectively located on two sides of the central axis 100 of the tank case 10. Meanwhile, the first through hole 151 and the second through hole 161 are arranged in a staggered manner, that is, the first through hole 151 and the second through hole 161 are respectively located on two sides of the central axis 100 of the fuel tank shell 10.

Referring to fig. 4 to 6, in the present embodiment, the oil tank shell 10 is equally divided into three equal parts by the first partition 15 and the second partition 16, and the first receiving cavity 200, the second receiving cavity 300, and the third receiving cavity 400 are communicated with each other and used for receiving lubricating oil. This flushing oil tank still includes: a first oil return pipe 41 and a second oil return pipe 42 vertically extending into the first accommodating cavity 200, and a plurality of third oil return pipes 11 vertically extending into the second accommodating cavity 300.

The oil mist suction hole 35 communicating with the third accommodation chamber 400 is provided at the top of the oil tank case 10.

The mist suction hole 35 may be connected to a mist separator (not shown), and the mist separator may convert the mist-like lubricant oil into liquid lubricant oil again, and the liquid lubricant oil falls into the third accommodating cavity 400 again to prevent the mist from damaging the environment. The lubricating oil flowing back into the tank housing 10 from the first oil return pipe 41 and the second oil return pipe 42 can play an effective buffering role through the first partition plate 15 and the second partition plate 16, and the lubricating oil flows around the inside of the tank housing 10 along the flow paths shown by the arrows a and B in fig. 1 and 2, so that the impact and vibration on the flushing tank caused by the flowing of the lubricating oil in the flushing tank are effectively avoided, and the lubricating oil is prevented from mixing bubbles in the flowing process of the lubricating oil in the flushing tank.

Meanwhile, the flushing oil tank shown in this embodiment further includes a plurality of lubricant output holes disposed at the bottom of the oil tank shell 10 and communicated with the third accommodating cavity 400. Specifically, referring to fig. 2, in the present embodiment, a lubricant output hole 31 and a lubricant output hole 32 are disposed at the bottom of the oil tank shell 10, and the

lubricant output holes

31 and 32 are connected to a lubricant circulation device (not shown), so that lubricant is pumped from the

lubricant output holes

31 and 32 to a device requiring lubrication by using lubricant, and the lubricant is filtered by a filtering device and then pumped to the first accommodating cavity 200 through the first oil return pipe 41 and the second oil return pipe 42 again. Since the lubricating oil contained in the oil tank case 10 is usually maintained at 60 degrees centigrade or higher, oil mist is generated inside the oil tank case 10, and therefore, the first balance vent 152 and the second balance vent 162 are opened on the top plate close to the oil tank case 10, so that the oil mist in the first containing cavity 200, the second containing cavity 300 and the third containing cavity 400 formed by the oil tank case 10 can be communicated with each other and attached to the top plate, and collected into the third containing cavity 400 through the first balance vent 152 and the second balance vent 162, and discharged from the oil mist suction hole 35. Referring to fig. 2 and 3, the tank shell 10 is further provided with a port 33 and a port 34 respectively disposed at one side of the third accommodating cavity 400 for connecting a liquid level meter (not shown) and arranged up and down, so as to connect the liquid level meter with the port 34 through the port 33, so as to display the level of the lubricating oil in the tank shell 10.

The first oil return pipe 41 and the second oil return pipe 42 return the lubricating oil into the first accommodating cavity 200, and the blocking portion 153 blocks the falling lubricating oil, and the lubricating oil flows into the second accommodating cavity 300 from the first through hole 151 along the direction indicated by the arrow a. Then flows into the third receiving cavity 400 in the direction indicated by the arrow B. In this embodiment, since the lubricant output hole 31 and the lubricant output hole 32 are communicated with the third accommodating cavity 400, the lubricant output hole 31 and the lubricant output hole 32 are prevented from directly pumping the lubricant which just falls down, so that the flow of the lubricant in the oil tank shell 10 is smoother, and air is prevented from being mixed into the lubricant.

Referring to fig. 1 to 3, the flushing oil tank shown in this embodiment further includes a plurality of third oil return pipes 11 vertically extending into the second accommodating cavity 300, and specifically, four third oil return pipes 11 are provided. The third return line is used to receive the returned lubricating oil of a relief valve (not shown) and a pressure return system (not shown) provided in the seal oil station. Meanwhile, four third oil return pipes 11 are disposed adjacent to the first partition 15. In the embodiment, the first oil return pipe 41, the second oil return pipe 42 and the four third oil return pipes 11 all extend vertically to the bottom of the tank case 10.

In this embodiment, a manhole 51 communicating with the first receiving chamber 200 is provided at the top of the tank case 10. So that the operator can conveniently enter the tank shell 10 through the manhole 51 to repair the pipes or components arranged in the tank shell 10.
