Description

Technical Field

[0001] This utility model relates to the field of marine equipment technology, and in particular to a pollution-proof and breathable cap with an oil drip tray. Background Technology

[0002] Existing standard marine oil tank vent caps are typically designed and installed in open areas of the vessel, directly exposing them to the external environment. During navigation and operations, a large number of oil droplets continuously accumulate inside the vent cap and overflow. These droplets mix with rainwater during rainy weather, forming oily wastewater. This type of oily wastewater not only causes severe oil pollution on the ship's deck surface, but also, especially when it accumulates at the top of the funnel, it is extremely difficult to clean due to its high location and complex structure, significantly increasing cleaning costs. Long-term accumulated oil pollution not only affects the ship's appearance and environmental hygiene, but also creates a continuous maintenance burden, significantly increasing subsequent oil pollution treatment costs and overall operating costs. Utility Model Content

[0003] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, an embodiment of this utility model proposes a pollution-proof and breathable cap with an oil drip tray, comprising a vent pipe, a reducing connector, an elbow, a rain cover, an oil drip tray, and an oil pipe; the lower end of the reducing connector is attached to the end of the vent pipe; one end of the elbow is attached to the upper end of the reducing connector, and both ends of the elbow face downwards; the rain cover is attached to the other end of the elbow via a flange; the oil drip tray is disposed below the rain cover;

[0004] One end of the oil pipe is connected to the oil outlet of the oil dripping plate, and the other end of the oil pipe is connected to the vent pipe, so that the oil on the oil dripping plate flows into the vent pipe.

[0005] According to some embodiments of this utility model, a fireproof net is installed inside the elbow, and the fireproof net is located above the rainproof cover.

[0006] According to some embodiments of the present invention, the rain cover includes a main body and a side baffle. The main body is connected to the flange, and a side baffle is provided on the outer side of the main body. The side baffle is in the shape of an inverted L and surrounds the periphery of the drip tray.

[0007] According to some embodiments of the present invention, the oil pipe includes a vertical pipe section and an inclined pipe section. One end of the vertical pipe section is connected to the oil outlet of the oil drip tray, the other end of the vertical pipe section is connected to one end of the inclined pipe section, and the other end of the inclined pipe section is connected to the vent pipe.

[0008] According to some embodiments of this utility model, the elbow is a U-shaped bend.

[0009] This utility model has at least the following beneficial effects:

[0010] The main function of the oil drip tray is to collect and receive oil droplets that may be generated during equipment operation. These droplets flow smoothly through the connected oil pipes and eventually enter the vent pipe, from where they are guided back into the oil tank. This design not only effectively prevents oily substances from polluting the external environment, but the equipment is also equipped with a rain cover, which effectively blocks rainwater or other external liquids from entering the oil tank vent pipe, thus preventing the internal oil from being contaminated or undergoing unnecessary dilution. This device has a reasonable structure and is a highly efficient vent cap solution that integrates safety, reliability, and environmental protection.

[0011] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0012] The first and / or additional aspects and advantages of this utility model will become apparent and readily understood from the description of the embodiments taken in conjunction with the following drawings, in which:

[0013] Figure 1 This is a schematic diagram of an embodiment of the present utility model. Detailed Implementation

[0014] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0015] In the description of this utility model, the meaning of "first" is that "greater than", "less than", "exceeding", etc., are understood to exclude the stated number. If "first" and "second" are used in the description, they are only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0016] like Figure 1 As shown, a pollution-proof and breathable cap with an oil drip tray includes a breathable pipe 100, a reducing connector 200, an elbow 300, a rain cover 400, an oil drip tray 500, and an oil pipe 600; the lower end of the reducing connector 200 is firmly installed on the pipe end of the breathable pipe 100 to ensure a tight connection without leakage, while increasing the breathable flow area.

[0017] One end of the elbow 300 is connected to the upper end of the reducer 200. The elbow 300 adopts a U-shaped structure design to ensure that the oil and gas cooling enters the oil drip tray 500. Both ends of the elbow face downward to facilitate the flow of oil and gas. The rain cover 400 is installed at the other end of the elbow 300 through the flange 800 connection to protect it from rain and foreign objects.

[0018] The oil drip tray 500 is located directly below the rain cover 400 to collect leaked oil. One end of the oil pipe 600 is connected to the oil outlet of the oil drip tray 500 through a sealed joint, while the other end of the oil pipe 600 is connected to the side wall or bottom of the vent pipe 100, thus forming a complete return path. This allows the oil accumulated on the oil drip tray 500 to flow smoothly into the vent pipe 100 and then be guided back into the oil tank, effectively preventing oil from polluting the external environment. Equipped with the rain cover 400, this component effectively blocks rainwater or other external liquids from entering the oil tank vent pipe 100, thereby preventing the internal oil from being contaminated or undergoing unnecessary dilution. This device has a reasonable structure and is a highly efficient vent cap solution that integrates safety, reliability, and environmental protection.

[0019] In addition, the elbow 300 is equipped with a fireproof mesh 700, which is located above the rain cover 400. This fireproof mesh 700 can effectively block flames or sparks from entering the ventilation system and improve the safety of the equipment.

[0020] The rain cover 400 consists of a main body 410 and side baffles 420. The main body 410 is directly connected to the flange 800. The outer side of the main body 410 is provided with inverted L-shaped side baffles 420. These side baffles 420 are arranged around the periphery of the oil drip tray 500 to further enhance the rain and dust protection effect and ensure that rainwater cannot enter the oil drip tray 500.

[0021] The oil pipe 600 is specifically divided into two parts: a vertical pipe section 610 and an inclined pipe section 620. One end of the vertical pipe section 610 is vertically connected to the oil outlet of the drip tray 500, and the other end is connected to the inclined pipe section 620 at a certain angle. The end of the inclined pipe section 620 is connected to the vent pipe 100. This structural design is conducive to the natural flow of oil by gravity, reducing the risk of blockage.
