Description

Technical Field

[0001] The utility model relates to the technical field of ship maintenance, in particular to steam cleaning equipment for a ship's dirty oil tank. Background Art

[0002] A ship is a man-made means of transport that mainly operates in geographical waters. In addition, civilian ships are generally called ships, military ships are called warships, and small ships are called boats or boats. They are collectively called ships or boats. The interior mainly includes accommodation space, support structure and drainage structure, and has a propulsion system that uses external or self-contained energy. When a ship is in use, if the dirty oil in the dirty oil tank cannot be cleaned in time, it will affect the working condition of the ship to a certain extent.

[0003] After searching, in the prior art, the utility model with publication number CN209222813U discloses a steam cleaning device for a ship's dirty oil tank, including a steam pipe and a steam control valve externally connected to one end of the steam pipe, the steam pipe is provided with a purge hole, the purge hole is divided into two holes and one hole and is evenly arranged crosswise on the steam pipe, the end of the steam pipe is also provided with a sealing plate for plugging, and a sleeve is provided between the steam control valve and the steam pipe. High-temperature and high-pressure steam enters the steam pipe through the steam control valve. Since the other end is closed with a sealing plate, the high-temperature and high-pressure steam is ejected from the purge hole provided on the steam pipe to clean the dirty oil tank. The steam commonly used on ships is used as a medium to clean the dirty oil tank. Since the steam of the ship system has the characteristics of high temperature and high pressure, the dirty oil stuck inside the oil tank can be easily removed. This system is connected to the steam system outside the oil tank, and no personnel are required to enter the interior for cleaning work, which can reduce the labor load of the crew and is safe and reliable. This method uses steam pipes to transport ship steam and automatically cleans the dirty oil through steam, reducing the workload of staff. However, this method still has the following shortcomings: when the device is not in use, the dirty oil accumulated in the dirty oil tank is easy to drip into the purge hole, thereby clogging the purge hole, and the purge hole is not easy to clean, resulting in poor practicality of the device. Utility Model Content

[0004] The utility model aims to provide a steam cleaning device for a ship's dirty oil tank to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: comprising a pipeline, the outer ring of the pipeline is provided with a plurality of exhaust holes, the inner cavity of the exhaust hole is provided with an exhaust pipe, the inner wall of the exhaust pipe is fixedly provided with a fixing block, the top of the fixing block is provided with a sliding rod, the outer ring of the sliding rod is provided with a sliding block, the outer ring of the sliding block is connected to a connecting rod, and one end of the connecting rod is connected to a sealing block.

[0006] Preferably, a through hole is formed through the inner cavity of the sliding block from top to bottom, and the through hole is movably connected to the sliding rod.

[0007] Preferably, a limit block is movably provided at one end of the slide rod, and a return spring is provided between the limit block and the slide block.

[0008] Preferably, the sealing block is made of rubber material, a cover plate is provided at one end of the sealing block, the setting diameter of the cover plate is consistent with the setting diameter of the exhaust pipe, and the cover plate is made of PVC material.

[0011] Preferably, a connecting hole is provided at the bottom of the limiting block, and one end of the sliding rod is connected to the connecting hole via a thread.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The ship's dirty oil tank steam cleaning equipment uses a slider, a reset spring, a connecting rod and a sealing block. When the steam stops outputting or the device is in a closed state, the reset spring loses pressure and rebounds the slider. At this time, the slider pulls the sealing block through the connecting rod until the sealing block is stuck in the inner cavity of the exhaust pipe. At this time, the exhaust pipe will be blocked by the sealing block to prevent the exhaust hole from being blocked by dirty oil, thereby improving the practicability of the device.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example: See Figure 1-5 The utility model provides a technical solution: a steam cleaning device for a ship's dirty oil tank, comprising a pipeline 1, a plurality of exhaust holes 3 are opened on the outer ring of the pipeline 1, an exhaust pipe 4 is arranged in the inner cavity of the exhaust hole 3, a fixing block 5 is fixedly arranged on the inner wall of the exhaust pipe 4, a sliding rod 6 is arranged on the top of the fixing block 5, a sliding block 7 is sleeved on the outer ring of the sliding rod 6, a connecting rod 9 is connected to the outer ring of the sliding block 7, and a sealing block 10 is connected to one end of the connecting rod 9.

[0022] The inner cavity of the slider 7 is provided with through holes 8 extending upward and downward, and the through holes 8 are movably connected to the slide rod 6 .

[0023] A limit block 12 is movably provided at one end of the slide rod 6 , and a return spring 14 is provided between the limit block 12 and the slide block 7 .

[0024] In this embodiment, refer to Figure 1 The device has four exhaust pipes 4 in a row, and there are three rows of exhaust pipes 4, which are distributed in a ring shape on the outer circle of the pipeline 1. When the pipeline 1 is filled with steam, the steam can be discharged in different directions through the multiple rows of exhaust pipes 4, so that the steam can be more evenly dispersed in the inner cavity of the dirty oil tank, so that the device can clean the dirty oil more efficiently.

[0025] When steam enters the inner cavity of the exhaust pipe 4 through the exhaust hole 3, the steam pushes the sealing block 10, and the sealing block 10 drives the slider 7 to move through the connecting rod 9, thereby squeezing the return spring 14, so that a distance is left between the sealing block 10 and the exhaust pipe 4 to facilitate the discharge of steam.

[0026] When the steam output stops or the device is in the closed state, the return spring 14 loses pressure and rebounds the slider 7. At this time, the slider 7 pulls the sealing block 10 through the connecting rod 9 until the sealing block 10 is stuck in the inner cavity of the exhaust pipe 4. At this time, the exhaust pipe 4 will be blocked by the sealing block 10 to prevent the exhaust hole 3 from being blocked by dirty oil, thereby improving the practicality of the device.

[0027] Reference Figure 3Two slide bars 6 are arranged in the exhaust pipe 4 of the device, and are symmetrical with the exhaust pipe 4 as the center. The slide bars 6 are used to limit the moving track of the sealing block 10 to ensure that the sealing block 10 can be accurately pulled back into the inner cavity of the exhaust pipe 4.

[0028] In actual use, the position and number of the exhaust pipes 4 can be determined as needed, and this device does not impose any restrictions on this.

[0029] The sealing block 10 is made of rubber, and a cover plate 11 is arranged at one end of the sealing block 10 . The diameter of the cover plate 11 is consistent with the diameter of the exhaust pipe 4 , and the cover plate 11 is made of PVC.

[0030] In this embodiment, the rubber has good flexibility, and after the device is used for a long time, there will be no gap between the sealing block 10 and the exhaust pipe 4 due to long-term friction.

[0031] The cover plate 11 is used to block the connection between the sealing block 10 and the outside world, which can prevent the sealing block 10 from being corroded by dirty oil, thereby extending the service life of the device. In addition, the PVC material is relatively light, which can facilitate the steam to push the sealing block 10.

[0032] One end of the exhaust hole 3 is rounded.

[0033] In this embodiment, refer to Figure 5 The steam enters the inner cavity of the exhaust hole 3 along the inner wall of the pipe 1. After one end of the exhaust hole 3 is polished into a rounded corner, the amount of steam entering the exhaust hole 3 at one time can be increased to ensure that the thrust of the steam on the sealing block 10 is greater than the pressure of the return spring 14 on the slider 7.

[0034] The pipeline 1 is a seamless steel pipe, and a plurality of annular reinforcing ribs 2 are welded to the outer ring of the pipeline 1 .

[0035] In this embodiment, the seamless steel pipe has good sealing performance, which can prevent the steam in the pipeline 1 from leaking out.

[0036] The annular reinforcement rib 2 is used to improve the overall strength of the pipeline 1 and stabilize the shape of the pipeline 1 to prevent the pipeline 1 from being deformed due to a large temperature difference between the inside and the outside.

[0037] A connecting hole 13 is formed at the bottom of the limiting block 12 , and one end of the sliding rod 6 is connected to the connecting hole 13 via a thread.

[0038] In this embodiment, after the slide rod 6 is connected to the limit block 12 through the connecting hole 13, the limit block 12 can be easily removed, thereby facilitating the replacement of the reset spring 14 to prevent the reset spring 14 from being unable to reset the sealing block 10 due to aging and breakage.

[0039] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it 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 it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
