A supercharger air-permeable foreign matter prevention device

Abstract

This utility model relates to a turbocharger ventilation and foreign object prevention device, belonging to the field of shipbuilding technology. The turbocharger ventilation and foreign object prevention device includes: a treatment box; an exhaust pipe fixedly connected to the bottom of the treatment box, with its exhaust end extending into the interior of the treatment box; and an intake pipe fixedly connected to the top of the treatment box, with its intake end extending into the interior of the treatment box, and the exhaust end of the exhaust pipe positioned above the intake end of the intake pipe. This device forces gas to flow in a "~" shaped path through a baffle, increasing the settling time and difficulty of particulate matter. The inverted conical bottom wall design inside the treatment box, combined with the drain pipe, enables directional collection of foreign objects. Gas must move downwards and pass over the baffle before rising into the intake pipe, effectively reducing the probability of salt spray particles escaping with the airflow. This flow path allows heavier solid impurities to escape the airflow under the combined action of centrifugal force and gravity, fundamentally reducing the risk of foreign object intrusion into the turbocharger.

Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and in particular to a turbocharger ventilation and foreign object prevention device. Background Technology

[0002] As a key component for increasing the power output of marine main engine turbochargers, the vent pipes of these turbochargers play a crucial role in balancing internal pressure, expelling exhaust gases, and introducing air. However, existing vent pipe designs suffer from the following technical defects:

[0003] Vent pipes are typically directly connected to the atmosphere and lack efficient filtration devices, allowing foreign matter such as salt spray particles and dust from the marine environment to easily enter the turbocharger. Such foreign matter can exacerbate turbine blade wear and even cause mechanical failures such as bearing jamming. A typical case shows that a ship experienced bearing failure due to foreign matter entering the turbocharger lubrication system, ultimately leading to main engine malfunction. Utility Model Content

[0004] Therefore, it is necessary to solve the problem of mechanical failure caused by foreign object intrusion due to the lack of a high-efficiency filtration device in the venting pipeline of the ship's main engine turbocharger, and to provide a turbocharger venting foreign object prevention device.

[0005] A booster venting and foreign object prevention device, comprising:

[0006] Processing box;

[0007] An exhaust pipe is fixedly connected to the bottom of the processing box, and the exhaust end of the exhaust pipe extends into the interior of the processing box.

[0008] An air inlet pipe is fixedly connected to the top of the processing box, with the air inlet end of the air inlet pipe extending into the interior of the processing box, and the air outlet end of the air outlet pipe located above the air inlet end of the air inlet pipe.

[0009] A partition is fixedly connected to the inner top wall of the processing box. The partition is located between the air outlet pipe and the air inlet pipe, and the bottom of the partition is located below the air inlet pipe.

[0010] An enhanced protection mechanism is installed inside the processing box.

[0011] In one embodiment, the processing box has a socket on its side, and the enhanced protection mechanism includes a mounting frame inserted into the socket. The top of the mounting frame has a cavity disposed inside the processing box, and a filter screen is detachably connected to the cavity.

[0012] In one embodiment, a square frame is inserted into the cavity, and the filter screen is embedded in the inner side of the square frame. An adjustment handle is rotatably connected to the inner side of the square frame and is positioned above the filter screen.

[0013] In one embodiment, the enhanced protection mechanism further includes two positioning frames, each fixedly connected between the processing box and the partition, with the mounting frame disposed between the two positioning frames.

[0014] In one embodiment, the vertical cross-sectional shape of the inner side of the mounting frame is an isosceles trapezoid, and the inner dimensions of the mounting frame gradually increase from the filter screen toward the mounting frame.

[0015] In one embodiment, a sealing ring is fitted onto the surface of the mounting frame, and the sealing ring contacts the socket.

[0016] In one embodiment, the bottom of the processing box is fixedly connected to and connected to a drain pipe.

[0017] In one embodiment, the bottom wall of the processing tank is inverted conical in shape, and the lowest point of the bottom wall of the processing tank is connected to the feed end of the drain pipe.

[0018] Beneficial effects

[0019] The aforementioned turbocharger's ventilated foreign object prevention device forces gas to flow in a "~" shaped path via a baffle, increasing the settling time and difficulty of particulate matter. The inverted conical bottom wall design inside the treatment chamber, combined with the drain pipe, enables directional collection of foreign objects. Gas must move downwards and pass over the baffle before rising to enter the intake pipe, effectively reducing the probability of salt spray particles escaping with the airflow. This flow path allows heavier solid impurities to be separated from the airflow under the combined action of centrifugal force and gravity, fundamentally reducing the risk of foreign object intrusion into the turbocharger.

[0020] The enhanced protection mechanism features a plug-in mounting frame combined with a removable filter screen, and an adjustable handle allows for quick replacement. The isosceles trapezoidal cross-section mounting frame, along with a sealing ring, ensures airtightness, while the positioning frame provides double support. This structure allows filter screen maintenance without disassembling pipe flanges; cleaning or replacement can be completed simply by pulling out the mounting frame, significantly reducing equipment downtime and maintenance costs.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The following is combined Figures 1-5 This invention describes a booster ventilator and foreign object prevention device.

[0031] In one embodiment, a booster venting and foreign object prevention device includes:

[0032] Processing box 100;

[0033] The vent pipe 200 is fixedly connected to the bottom of the processing box 100, and the vent end of the vent pipe 200 extends into the interior of the processing box 100.

[0034] An air inlet pipe 300 is fixedly connected to the top of the processing box 100. The air inlet end of the air inlet pipe 300 extends into the interior of the processing box 100, and the air outlet end of the air outlet pipe 200 is located above the air inlet end of the air inlet pipe 300.

[0035] The partition 400 is fixedly connected to the inner top wall of the processing box 100. The partition 400 is located between the air outlet pipe 200 and the air inlet pipe 300, and the bottom of the partition 400 is located below the air inlet pipe 300.

[0036] The bottom of the treatment box 100 is fixedly connected to and connected to a drain pipe 600.

[0037] The bottom wall of the processing box 100 is inverted conical in shape, and the lowest point of the bottom wall of the processing box 100 is connected to the feed end of the drain pipe 600.

[0038] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an enhanced protective mechanism 500 is installed inside the processing box 100. The processing box 100 has a side opening 110. The enhanced protective mechanism 500 includes a mounting frame 510 inserted into the opening 110. The top of the mounting frame 510 has a cavity 511 located inside the processing box 100. A filter screen 520 is detachably connected inside the cavity 511. A square frame 530 is inserted into the cavity 511, and the filter screen 520 is embedded inside the square frame 530. The inner side of the square frame 530 is rotatably connected... An adjustment handle 540 is provided, which is positioned above the filter screen 520. The enhanced protection mechanism 500 also includes two positioning frames 550, both of which are fixedly connected between the treatment box 100 and the partition 400. A mounting frame 510 is positioned between the two positioning frames 550. The vertical cross-sectional shape of the inner side of the mounting frame 510 is an isosceles trapezoid, and the inner dimension of the mounting frame 510 gradually increases from the filter screen 520 toward the mounting frame 510. A sealing ring 560 is fitted on the surface of the mounting frame 510, and the sealing ring 560 contacts the inlet 110.

[0039] In this embodiment, when the user needs to clean or replace the filter 520, the user first pulls the mounting frame 510 out of the socket 110, then lifts the adjustment handle 540. The adjustment handle 540 drives the frame 530 and the filter 520 to be removed from the socket 511 for cleaning or replacement. Then, the filter 520 can be easily installed and reset in reverse order.

[0040] The specific installation process for this equipment is as follows:

[0041] 1. Secure the processing box 100 to the floor of the compartment on the side of the diesel turbocharger using bolts;

[0042] 2. Connect the exhaust pipe 200 to the exhaust end of the diesel turbocharger via a flange connection;

[0043] 3. Connect the air inlet pipe 300 to the air inlet of the corresponding equipment via a flange connection;

[0044] 4. Connect the drain pipe 600 to the waste liquid tank in the waste oil tank via a flange connection.

[0045] Working principle:

[0046] Gas flow: Gas enters the treatment box 100 from the exhaust pipe 200 connected to the diesel turbocharger. At this time, the gas is blocked by the baffle 400 and moves down along the baffle 400. Only when the gas moves down and passes the baffle 400 can it rise into the intake pipe 300 and be discharged. During this process, the gas flows in a "~" path, which increases the difficulty for particles mixed in the gas to be discharged upward.

[0047] Foreign object interception: Since the filter screen 520 is located between the partition 400 and the air inlet pipe 300, the filter screen 520 can effectively filter solid impurities in the passing gas to ensure that the gas discharged from the air inlet pipe 300 is cleaner.

[0048] Foreign object discharge: The settled foreign objects are discharged through the drain pipe 600, which is connected to the lowest point of the bottom wall of the treatment box 100, to ensure the cleanliness of the inside of the treatment box 100 and prevent the accumulation of foreign objects.

[0049] Gas discharge: The filtered gas is discharged through the intake pipe 300 to the turbocharger or other subsequent treatment systems.

[0050] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
