Description

Technical Field

[0001] This invention relates to the field of marine exhaust technology, and in particular to a main engine crankcase that facilitates the removal of oil stains through louvers. Background Technology

[0002] As is well known, all types of ships are designed with an oil mist box in the funnel area, which is an independent cabinet where the vent pipes of the fuel oil and lubricating oil tanks in the engine room area are led to. Since some of the fuel oil and lubricating oil tanks are heated by steam to 50-80°C, the oil mist and hot gas in the fuel tanks will rush out of the vent pipes into the funnel oil mist box, and finally pass through the louvers of the oil mist box into the atmosphere.

[0003] Because traditional louver designs have the louvers tilted outward at a certain angle, this only achieves the effect of preventing rainwater. However, during the long-term process of oil mist seeping outward, the outer wall of the chimney (under the louvers) will be contaminated with oil stains. On rainy days, rainwater washes these oil stains from the bulkheads onto the deck and into the sea, polluting the environment. In addition, the oil stains also seriously affect the appearance of the ship. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art and to propose a main unit crank box that facilitates the removal of oil stains from louvers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A main unit crank box for easy cleaning of oil stains from louvers includes an oil mist box. The vent of the oil mist box is provided with a louver body. The oil mist box is connected to a vent pipe. The louver body includes a frame disposed within the vent and a plurality of louver blades disposed at equal intervals within the frame. The louvers are V-shaped, with the openings of the V-shaped louvers facing the inner wall of the oil mist box. A guide vane is inclinedly disposed on the side of the louvers facing away from the inner wall of the oil mist box. A lifting component for driving the louver body to move up and down reciprocally is provided on the vent pipe.

[0007] Preferably, the upper inclined plate of the guide vane and the louver is on the same plane, and the guide vane and the louver form a herringbone structure for oil and water blocking.

[0008] Preferably, the lifting assembly includes a rotating rod rotatably connected to the vent pipe. The rotating rod has a plurality of paddles evenly arranged in a circle on its body inside the vent pipe. The end of the rotating rod is provided with a first crank. A first collar is sleeved on the first crank. A first swing rod is fixedly provided on the first collar. The end of the first swing rod away from the first collar is movably connected to a movable rod that is slidably connected to the oil mist box. The movable rod is fixedly connected to the bottom of the frame.

[0009] Preferably, the upper and lower sides of the frame are provided with partitions connected to the louvers, and the partitions move against the inner wall of the oil mist box.

[0010] Preferably, a piston is fixed on the moving rod, and a pneumatic chamber for piston sliding is provided on the oil mist box. The piston divides the pneumatic chamber into upper and lower chambers, and an air inlet channel communicating with the two chambers is provided on the oil mist box. Both chambers are connected to an air guide pipe. A one-way valve is provided in both the air inlet channel and the air guide pipe. The end of the air guide pipe away from the chamber passes through the frame and is connected to an air jet port, which is located on the frame.

[0011] Preferably, a rain shield is fixed on the oil mist box, and the rain shield is positioned above the air inlet of the air intake channel.

[0012] Preferably, the rotating rod is provided with a second crank, the second crank is fitted with a second collar, the second collar is fixedly provided with a second rocker arm, the end of the second rocker arm away from the second collar is movably connected to a movable rod that is slidably connected to the oil mist box, the movable rod is fixedly provided with a pull rope, and the end of the pull rope away from the movable rod is connected to an oil scraping part that moves against the V-shaped louvers.

[0013] Preferably, a fixed plate is fixedly provided on the inner wall of the oil mist box, and the oil scraping part includes a movable plate fixedly connected to the pull rope. The movable plate is slidably connected to the fixed plate. A first elastic element is provided between the movable plate and the fixed plate. An elastic telescopic plate is connected to the end of the movable plate away from the pull rope. The elastic telescopic plate moves against the inclined surfaces on the upper and lower sides of the louver.

[0014] Preferably, the elastic telescopic plate includes a housing fixedly connected to the movable plate, and scrapers are slidably connected to both the upper and lower sides of the housing. The upper and lower scrapers respectively move against the inclined surfaces of the upper and lower sides of the louver blade, and a second elastic element is provided between the scraper and the housing.

[0015] Preferably, a fireproof mesh is fixed to the frame of the louver.

[0016] Compared with the prior art, the present invention provides a main unit crankcase that facilitates the cleaning of oil stains from louvers, and has the following beneficial effects:

[0017] 1. The main crank box of the main unit, which facilitates the removal of oil stains from the louvers, is equipped with herringbone-shaped louvers to ensure full contact between oil and gas and the stainless steel louver body. This facilitates the condensation of oil and gas, makes it easier to intercept oil and gas, and prevents oil and gas pollution of ships or oceans. In addition, the lifting component facilitates the up-and-down reciprocating vibration of the louvers, which makes the condensed oil droplets on the louvers fall down quickly, ensuring the continuous condensation effect of subsequent oil and gas.

[0018] 2. The main unit crank box, which facilitates the removal of oil stains from the louvers, moves the louver body up and down repeatedly through the lifting component. The oil scraping part quickly scrapes off the oil droplets attached to the louvers, which facilitates rapid condensation of oil and gas when they come into contact with the louvers, ensuring the condensation efficiency and effect of the oil and gas.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] Example: Refer to Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7 A main unit crank box for easy cleaning of oil stains from louvers includes an oil mist box 1. The vent 101 of the oil mist box 1 is provided with a louver body 2. The oil mist box 1 is connected to a vent pipe 102. The louver body 2 includes a frame 201 disposed in the vent 101 and a plurality of louver blades 202 disposed at equal intervals in the frame 201. The louver blades 202 are V-shaped, and the openings of the V-shaped louver blades 202 face the inner wall of the oil mist box 1. A guide vane 2021 is inclinedly disposed on the side of the louver blades 202 away from the inner wall of the oil mist box 1. A lifting component for driving the louver body 2 to move up and down is provided on the vent pipe 102.

[0031] Furthermore, the upper inclined plates of the guide vane 2021 and the louver 202 are on the same plane, and the guide vane 2021 and the louver 202 form a herringbone structure for oil blocking and waterproofing.

[0032] Specifically, oil and gas enter the oil mist box 1 through the vent pipe 102, and then are discharged through the louvered window 2 at the vent 101. The louvers 202 of the louvered window 2 intercept and condense most of the oil and gas, greatly reducing the oil content in the oil and gas. During the flow of oil and gas in the vent pipe 102, the lifting component is controlled to move, causing the lifting component to move the louvered window 2 up and down at the vent 101. By forming a herringbone louvered window 202 structure, the oil and gas can fully contact the stainless steel louvered window 202, which is conducive to the condensation of oil and gas, facilitates the interception of oil and gas, and avoids oil and gas pollution of ships or oceans. In addition, the setting of the lifting component is conducive to the up and down shaking of the louvered window 202, so that the oil droplets condensed on the louvered window 202 fall down quickly, ensuring the continuous condensation effect of subsequent oil and gas.

[0033] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As a preferred technical solution of the present invention, the lifting assembly includes a rotating rod 3 rotatably connected to the vent pipe 102. The rotating rod 3 is placed in the vent pipe 102 and a plurality of paddles 301 are evenly arranged in a circle on the rod body. The end of the rotating rod 3 is provided with a first crank 4. A first collar 401 is sleeved on the first crank 4. A first swing rod 402 is fixedly provided on the first collar 401. The end of the first swing rod 402 away from the first collar 401 is movably connected to a movable rod 5 that is slidably connected to the oil mist box 1. The movable rod 5 is fixedly connected to the bottom of the frame 201.

[0034] Furthermore, the upper and lower sides of the frame 201 are provided with partitions 2011 connected to the louvers 202, and the partitions 2011 move against the inner wall of the oil mist box 1.

[0035] Specifically, the oil and gas flow in the vent pipe 102 drives the paddle 301. It should be noted that a guide block is set in the vent pipe 102 to guide the oil and gas to blow the paddle 301. This is common knowledge to those skilled in the art and will not be elaborated here. When the paddle 301 rotates, it drives the rotating rod 3 to rotate. The rotating rod 3 drives the first crank 4 to rotate. The first crank 4 drives the first swing rod 402 to move through the first collar 401, so that the first swing rod 402 drives the moving rod 5 up and down in the oil mist box 1. The reciprocating movement causes the moving rod 5 to move the louver 2 up and down at the vent 101. As the louver 2 moves up and down, it also moves the partition 2011, preventing leakage from the upper and lower ends of the vent 101 when the louver 2 moves up and down. This would prevent excessive oil and gas from being discharged without being intercepted and condensed by the louver blades 202, thus avoiding excessive pollution. Furthermore, the reciprocating vibration of the louver blades 202 causes the condensed oil droplets on the louver blades 202 to fall quickly, ensuring the continuous condensation effect of subsequent oil and gas.

[0036] Reference Figure 1, Figure 2 , Figure 3 and Figure 4 As a preferred technical solution of the present invention, a piston 501 is fixed on the moving rod 5, and a pneumatic cavity 6 for sliding the piston 501 is opened on the oil mist box 1. The piston 501 divides the pneumatic cavity 6 into upper and lower cavities, and an air inlet channel communicating with the two cavities is opened on the oil mist box 1. Both cavities are connected to an air guide pipe 7. A one-way valve is provided in both the air inlet channel and the air guide pipe 7. The end of the air guide pipe 7 away from the cavity passes through the frame 201 and is connected to a jet nozzle 701. The jet nozzle 701 is opened on the frame 201.

[0037] Furthermore, a rain shield 8 is fixed on the oil mist box 1, and the rain shield 8 is placed on the upper side of the air intake of the air intake channel.

[0038] Specifically, when the moving rod 5 drives the louver body 2 to move up and down at the vent 101, the piston 501 on the outside of the moving rod 5 moves up and down in the pneumatic chamber 6, causing the piston 501 to alternately draw in and exhaust air through the upper and lower chambers. The pneumatic chamber 6 draws in outside air through the one-way valve at the air inlet channel, and then exhausts the air through the air guide pipe 7. The jet nozzle 701 on the frame 201 directs the gas out. The exhaust gas blows the oil droplets condensed on the louver 202, causing the oil droplets condensed on the louver 202 to fall quickly, ensuring the continuous condensation effect of the oil and gas.

[0039] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As a preferred technical solution of the present invention, a second crank 9 is provided on the rotating rod 3, a second collar 901 is sleeved on the second crank 9, a second rocker arm 902 is fixed on the second collar 901, and a movable rod 10 that is slidably connected to the oil mist box 1 is movably connected to the end of the second rocker arm 902 away from the second collar 901. A pull rope 1001 is fixed on the movable rod 10, and an oil scraping part that moves against the V-shaped louver 202 is connected to the end of the pull rope 1001 away from the movable rod 10.

[0040] Furthermore, a fixed plate 12 is fixedly provided on the inner wall of the oil mist box 1, and the oil scraping part includes a movable plate 11 fixedly connected to the pull rope 1001. The movable plate 11 is slidably connected to the fixed plate 12. A first elastic element 111 is provided between the movable plate 11 and the fixed plate 12. An elastic telescopic plate 13 is connected to the end of the movable plate 11 away from the pull rope 1001. The elastic telescopic plate 13 moves against the inclined surfaces on the upper and lower sides of the louver 202.

[0041] Furthermore, the elastic telescopic plate 13 includes a housing 131 fixedly connected to the movable plate 11. Scrapers 132 are slidably connected to both the upper and lower sides of the housing 131. The upper and lower scrapers 132 respectively move against the inclined surfaces on the upper and lower sides of the louver 202. A second elastic element 133 is provided between the scraper 132 and the housing 131.

[0042] Specifically, when the rotating rod 3 of the lifting assembly rotates, it drives the second crank 9 to rotate. When the second crank 9 rotates, it drives the second swing rod 902 to move through the second collar 901, causing the second swing rod 902 to drive the movable rod 10 to move up and down reciprocally within the oil mist box 1. When the movable rod 10 moves up and down reciprocally, it pulls the movable plate 11 back and forth through the pull rope 1001. The movable plate 11 slides relative to the fixed plate 12. When the pull rope 1001 pulls the movable plate 11, the movable plate 11 moves to the right. When the pull rope 1001 does not pull the movable plate 11, the movable plate 11 moves to the left under the elastic force of the first elastic element 111, causing the movable plate 11 to drive the elastic telescopic plate 13 to move left and right reciprocally. The scraper 132, which is elastically connected to the outer shell 131, can always abut against the louver 202. When the elastic telescopic plate 13 moves, it scrapes off the oil droplets condensed on the louver 202 through the scraper 132, which facilitates rapid condensation of oil and gas when they come into contact with the louver 202, ensuring the condensation efficiency and condensation effect of the oil and gas.

[0043] Reference Figure 1 As a preferred technical solution of the present invention, a fireproof net 14 is fixed on the frame 201 of the louver 2.

[0044] Specifically, fireproof mesh 14 is installed on the outside of the louver 2 to improve its protective performance.

[0045] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
