DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] See Figure 1 , the present utility model provides an oil-collecting mushroom-shaped ventilation duct, which includes an air outlet cylinder body 3, and a wind cap 2 is coaxially and fixedly sleeved at the upper port of the air outlet cylinder body 3;

[0025] An oil receiving tray 1 is also fixedly sleeved on the outer wall of the air outlet cylinder body 3 and is located below the wind cap 2; a baffle plate 11 is annularly arranged around the oil receiving tray 1; a ventilation opening is formed between the upper end of the baffle plate 11 and the lower end of the wind cap 2;

[0026] A oil filtering and ventilation assembly 4 is arranged between the outer wall of the air outlet cylinder body 3 and the inner wall of the wind cap 2 and is located above the oil receiving tray 1; the oil filtering and ventilation assembly 4 is configured such that when the exhaust gas passes through, the oil vapor mixed therein condenses into a liquid state; after the oil vapor condenses into a liquid state, oil droplets are formed and fall into the oil receiving tray 1. The exhaust gas from which the oil vapor has been removed is discharged from the ventilation opening.

[0027] The present utility model condenses the oil vapor in the exhaust gas through the oil filtering and ventilation assembly 4 and collects the liquid oil droplets in the oil receiving tray 1. The oil vapor in the exhaust gas is removed from the source, avoiding the formation of an oil film on the deck surface. The potential safety hazard of personnel slipping is eliminated.

[0028] See Figure 2 , as an embodiment, the oil filtering and ventilation assembly 4 of the present invention includes a metal mesh 41, and a plurality of mesh holes are uniformly arranged on the metal mesh 41; the exhaust gas passes through the mesh holes, and after the oil vapor mixed therein contacts the metal mesh, the temperature decreases and condenses into a liquid state and adheres to the metal mesh. After accumulating into oil droplets, they drip into the oil receiving tray 1.

[0029] Furthermore, two side edges of the metal mesh 41 are respectively fixed on edge plates 42; annular plates 31 are fixedly arranged on the outer wall of the air outlet cylinder body 3 and the inner wall of the wind cap 2; the edge plates 42 are fixedly connected to the corresponding annular plates 31; preferably, the edge plates 42 and the annular plates 31 are connected by bolts, which is convenient for installation, maintenance and replacement operations.

[0030] Furthermore, a plurality of vertically downward guide needles 43 are fixedly connected to the metal mesh 41, and the guide needles 43 are made of metal, which is convenient for oil droplets to adhere and condense and guides the oil droplets to drip.

[0031] As an embodiment, the width L of the ventilation opening 开 ≥200 mm, which has enough space to facilitate the operation personnel to maintain the oil filtering and ventilation assembly 4 and clean the oil receiving tray 1.

[0032] Meanwhile, the ventilation opening has enough width to enable there to be enough space above the oil receiving tray 1 for the air flow to be discharged smoothly.

[0033] Preferably, the cross-sectional shapes of the oil pan 1, the air outlet cylinder 3 and the wind cap 2 are all circular; the diameter of the oil pan 1 is larger than that of the wind cap 2; it can completely catch the oil droplets and prevent the oil droplets from falling onto the deck.

[0034] Preferably, the difference in diameter between the oil pan 1 and the wind cap 2 of the present utility model is not less than 40 mm. When the exhaust air flow velocity is relatively large, the oil droplets will not be blown out of the range of the oil pan 1.

[0035] As an embodiment, a drain hole 12 is provided at the bottom of the oil pan 1, and an oil collecting bucket 14 is provided below the drain hole 12; the oil in the oil pan 1 is collected in the oil collecting bucket 14 for unified treatment.

[0036] Optionally, the drain hole 12 is connected to a switch valve 13; the switch valve 13 is opened after a certain amount of oil has accumulated in the oil pan 1 to drain the oil.

[0037] Furthermore, the depth L of the oil pan 1 深 is not less than 30 mm, having sufficient capacity to hold the dripping oil.

[0038] See Figure 3 , as an embodiment, the oil pan 1 is inclined, and the drain hole 12 is provided at the lowest position of the oil pan 1; it is convenient for collecting oil liquid and cleaning.

[0039] Furthermore, the inclination angle of the oil pan 1 does not exceed 10°, preferably 5 - 10°.

[0040] See Figure 4 , as an embodiment, the cross-sectional shape of the oil pan 1 is arc-shaped; the air flow impacts the oil pan 1 and is guided to the air outlet, reducing the degree of air flow disorder and improving the exhaust efficiency.

[0041] As an embodiment, a blocking net 15 is fixedly arranged on the baffle plate 11 of the oil pan 1; the blocking net 15 is made of metal and is evenly provided with a plurality of ventilation holes; when the exhaust air flow temperature is relatively high, the flow rate is large or the speed is fast, the blocking net 15 forms a blockage to it, causing the residual oil vapor in the air flow to condense and separate.

[0042] In summary, the present utility model provides an oil-collecting mushroom-shaped ventilation pipe, which condenses the oil vapor in the exhaust gas through the oil-filtering ventilation component and collects the liquid oil droplets in the oil pan. The oil vapor in the exhaust gas is removed from the source, avoiding the formation of an oil film on the deck surface. The potential safety hazard of personnel slipping is eliminated.

[0043] Of course, the present utility model may also have many other embodiments. Without departing from the spirit and essence of the present utility model, those skilled in the art can make various corresponding changes and modifications according to the present utility model. However, these corresponding changes and modifications should all fall within the protection scope of the appended claims of the present utility model.
