Description

Technical Field

[0001] This utility model relates to the field of intercooler cleaning technology, and more specifically to an intercooler inner wall cleaning device. Background Technology

[0002] The ultra-high pressure compressor C-1202 of the LDPE / EVA unit is a key piece of equipment. It adopts a two-line symmetrical two-stage compression structure and is equipped with 10 cylinders. During operation, the first stage increases the feed gas pressure from 27MPa to 104.3MPa, and the second stage further pressurizes it to 300MPa. Since the intake temperature of both the first and second stages is set at 40℃, the gas compressed in the first stage needs to be cooled by the intercooler E-1202A / B. When producing EVA products in the high-pressure polyethylene industry, the introduction of VA monomers greatly increases the viscosity of the product. EVA products easily adhere to the inner wall of the intercooler. At the same time, during the cooling process, some ethylene and vinyl acetate self-polymerize to form fine powder, and the polymer layer continues to thicken, which seriously affects the heat exchange effect of the intercooler, resulting in a decrease in the unit load. When the wall adhesion is severe, it may even be necessary to shut down the unit, causing economic losses.

[0003] Currently, the pipes on the intercooler mainly use high-pressure water to clean the polymer on the inner wall. The high-pressure water nozzle is placed inside the pipe. Since the nozzle is always smaller than the pipe diameter, the nozzle is not directly located in the center of the pipe after it is placed inside. This results in different water pressures sprayed onto the inner wall of the pipe, which can damage the inner wall of the pipe, accelerate wear, and aggravate scaling. Moreover, during the spraying process, the nozzle is easily impacted by the water pressure against the inner wall of the pipe, which not only damages the pipe but also the nozzle itself, requiring more frequent nozzle replacements, increasing maintenance costs and material consumption. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an intercooler inner wall cleaning device to solve the problems existing in the background art.

[0005] The utility model provides the following technical solution: a cleaning device for the inner wall of an intercooler, including a fixed base, a feed pipe fixedly connected to the end face of the fixed base, a connecting groove opened at the center of the interior of the fixed base, sliding grooves equidistantly opened inside the fixed base and communicating with the interior of the connecting groove, a sealing plate slidably connected inside the sliding groove, a connecting plate fixedly connected at the center of the surface of the sealing plate away from the connecting groove, a roller rotatably connected to the surface of the connecting plate, a liquid passage groove opened inside the fixed base and communicating with the interior of the connecting groove, a driving assembly installed inside the liquid passage groove, a rotating plate fixedly connected to the output end of the driving assembly, a liquid inlet groove and a liquid injection groove opened inside the rotating plate, a fixed rod fixedly connected at equidistant intervals to the inner wall of the liquid inlet groove, a fixed plate fixedly connected to the end face of the fixed rod, a connecting pipe fixedly connected at equidistant intervals to the interior of the rotating plate and communicating with the interior of the liquid injection groove, and a high-pressure nozzle fixedly installed at the output end of the connecting pipe.

[0006] Furthermore, the drive assembly includes fixed rods that are equidistantly fixed to the inner wall of the liquid-passing tank. A fixed sleeve is fixedly connected to the end face of the fixed rod. A rotating shaft is rotatably connected to the inner center of the fixed sleeve via a bearing. An impeller is fixedly installed on the end face of the rotating shaft away from the rotating plate. The impeller is rotatably connected to the inside of the liquid-passing tank. The end face of the rotating shaft away from the impeller is fixedly connected to the center of the surface of the fixed plate. The inside of the liquid-passing tank is connected to the inside of the liquid-injection tank via an inlet tank.

[0007] Furthermore, a rotating ring is fixedly connected to the surface of the rotating plate near the fixed base, and a sealing ring is sleeved on the outer surface of the rotating ring. The rotating ring is rotatably connected to the inner wall of the liquid passage tank through the sealing ring.

[0008] Furthermore, a high-pressure water pipe is sleeved on the outer surface of the feed pipe, and a high-pressure water pump is fixedly installed at the input end of the high-pressure water pipe. The high-pressure water pump is placed in a storage tank containing xylene liquid.

[0009] Furthermore, the end of the connecting plate away from the sealing plate extends to the outside of the fixed base, and the outer surface of the connecting plate is slidably connected to the inside of the fixed base.

[0010] Furthermore, the feed pipe and the internal of the connecting groove are connected, the outer surface of the roller is fitted with a silicone rubber sleeve, the internal of the liquid injection groove is connected to the input end of the high-pressure nozzle through the connecting pipe, and the output end of the high-pressure nozzle extends to the outer surface of the rotating plate.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model uses a high-pressure nozzle to clean the inner wall of the intercooler pipes. The nozzle can rotate and spray cleaning fluid at the center of the pipe, ensuring that the xylene liquid sprayed from the high-pressure nozzle can evenly cover the inner wall of the pipe. Compared with the traditional method where the nozzle is not centered and causes uneven water pressure, this effectively avoids excessive local scouring and damage to the inner wall of the pipe, ensuring the cleaning effect while extending the service life of the pipe. At the same time, the rotating plate, together with the handheld feed pipe moving and fixing seat, achieves all-round cleaning of the inner wall of the pipe, thoroughly removing EVA products, fine powder and other polymers formed by the self-polymerization of ethylene and vinyl acetate adhering to the inner wall of the intercooler, restoring the heat exchange effect of the intercooler, reducing the load drop of the unit, avoiding shutdown due to severe wall adhesion, and reducing economic losses.

[0013] 2. In this utility model, when xylene liquid enters the sliding groove and pushes the sealing plate, causing the roller to abut against the inner wall of the pipe, the fixed seat can automatically be positioned at the center of the pipe, ensuring that the nozzle is always in the optimal spraying position during the cleaning process. By attaching a silicone rubber sleeve to the outer surface of the roller, the friction with the inner wall of the pipe is enhanced, ensuring the stability of the fixed seat and preventing scratch damage to the inner wall of the pipe. In addition, the connecting plate can slide inside the fixed seat, making it convenient to adjust the position of the fixed seat. Moreover, the overall structure is simple, easy to operate and maintain, reduces maintenance costs and material consumption, and greatly improves the practicality of the device.

[0021] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0022] Figures 1-6 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-6 The present invention will be further described below.

[0023] A device for cleaning the inner wall of an intercooler includes a fixed base 1, a feed pipe 2 fixedly connected to the end face of the fixed base 1, a connecting groove 7 formed at the center of the interior of the fixed base 1, sliding grooves 3 equidistantly formed inside the fixed base 1 and communicating with the interior of the connecting groove 7, a sealing plate 4 slidably connected inside the sliding groove 3, a connecting plate 5 fixedly connected at the center of the surface of the sealing plate 4 away from the connecting groove 7, a roller 6 rotatably connected to the surface of the connecting plate 5, a liquid passage groove 8 connected inside the fixed base 1 and communicating with the interior of the connecting groove 7, a drive assembly 9 installed inside the liquid passage groove 8, a rotating plate 10 fixedly connected to the output end of the drive assembly 9, a liquid inlet groove 11 and a liquid injection groove 14 formed inside the rotating plate 10, a fixed rod 12 fixedly connected at equidistant intervals to the inner wall of the liquid inlet groove 11, a fixed plate 13 fixedly connected to the end face of the fixed rod 12, a connecting pipe 15 equidistantly connected to the interior of the rotating plate 10 and communicating with the interior of the liquid injection groove 14, and a high-pressure nozzle 16 fixedly installed at the output end of the connecting pipe 15.

[0024] In this embodiment, the feed pipe 2 is used to transport the cleaning fluid. The connection groove 7 and the sliding groove 3 enable the cleaning fluid to push the sealing plate 4, which in turn drives the roller 6 to abut against the inner wall of the pipe, so that the fixed seat 1 is automatically centered, ensuring that the high-pressure nozzle 16 can spray the cleaning fluid at the center of the pipe. The coordinated operation of the liquid passage groove 8, the drive assembly 9, the rotating plate 10, the liquid inlet groove 11, the liquid injection groove 14, the connection pipe 15 and the high-pressure nozzle 16 enables the high-pressure nozzle 16 to rotate and spray the cleaning fluid at the center of the pipe, evenly covering the inner wall of the pipe, ensuring the cleaning effect while extending the service life of the pipe, and also achieving all-round cleaning, restoring the heat exchange effect of the intercooler, and reducing the load drop of the device.

[0025] Specifically, the drive assembly 9 includes a fixed rod 91 that is fixedly connected to the inner wall of the liquid passage 8 at equal intervals. A fixed sleeve 92 is fixedly connected to the end face of the fixed rod 91. A rotating shaft 93 is rotatably connected to the center of the fixed sleeve 92 via a bearing. An impeller 94 is fixedly installed on the end face of the rotating shaft 93 away from the rotating plate 10. The impeller 94 is rotatably connected to the inside of the liquid passage 8. The end face of the rotating shaft 93 away from the impeller 94 is fixedly connected to the center of the surface of the fixed plate 13. The inside of the liquid passage 8 is connected to the inside of the liquid injection tank 14 via the liquid inlet tank 11.

[0026] In this embodiment, during the cleaning process, the liquid flowing in the liquid tank 8 impacts the impeller 94, causing it to rotate. The impeller 94 drives the rotating shaft 93 to rotate, which in turn causes the fixed plate 13 to drive the rotating plate 10 to rotate via the fixed rod 12. This allows the high-pressure nozzle 16 to rotate and spray the cleaning liquid at the center of the pipe, making the cleaning liquid more evenly cover the inner wall of the pipe and improving the cleaning effect. At the same time, this structure uses the power of the liquid flow to drive the rotating plate 10 to rotate, eliminating the need for an additional power source, simplifying the device structure and reducing costs.

[0027] Specifically, a rotating ring 17 is fixedly connected to the surface of the rotating plate 10 near the fixed base 1. A sealing ring 18 is sleeved on the outer surface of the rotating ring 17. The rotating ring 17 is rotatably connected to the inner wall of the liquid passage tank 8 through the sealing ring 18.

[0028] In this embodiment, the cooperation between the rotating ring 17 and the sealing ring 18 ensures that the rotating plate 10 can rotate smoothly and sealed within the liquid tank 8, preventing leakage of the cleaning fluid and ensuring that all the cleaning fluid can be sprayed out through the high-pressure nozzle 16, thereby improving cleaning efficiency. On the other hand, the sealing effect of the sealing ring 18 can also maintain a certain pressure within the liquid tank 8, enhancing the spraying effect of the cleaning fluid and further ensuring the cleaning quality.

[0029] Specifically, a high-pressure water pipe is sleeved on the outer surface of the feed pipe 2, and a high-pressure water pump is fixedly installed at the input end of the high-pressure water pipe. The high-pressure water pump is placed in a storage tank containing xylene liquid.

[0030] In this embodiment, a high-pressure water pump draws xylene liquid from the storage tank and delivers it to the cleaning device under high pressure through a high-pressure water pipe and feed pipe 2, providing power for the entire cleaning process. This allows the xylene liquid to smoothly enter the liquid-passing tank 8, sliding tank 3, and subsequent liquid-inlet tank 11, injection tank 14, and other structures, ensuring that the high-pressure nozzle 16 can spray cleaning fluid with sufficient pressure to effectively remove dirt from the inner wall of the intercooler and meet the cleaning requirements. Since xylene has good solubility for these polymers, it can effectively dissolve and remove dirt such as EVA products, fine powder formed by the self-polymerization of ethylene and vinyl acetate adhering to the inner wall of the intercooler. Compared with traditional high-pressure water cleaning, the cleaning effect is better and the heat exchange effect of the intercooler can be restored more thoroughly.

[0031] Specifically, the end of the connecting plate 5 away from the sealing plate 4 extends to the outside of the fixed base 1, and the outer surface of the connecting plate 5 is slidably connected to the inside of the fixed base 1.

[0032] In this embodiment, the position of the fixed seat 1 can be flexibly adjusted by the sliding connecting plate 5 to adapt to intercooler pipes of different positions and shapes, which improves the applicability and ease of operation of the device and facilitates better cleaning of the inner wall of the intercooler pipes.

[0033] Specifically, the feed pipe 2 and the connecting groove 7 are internally connected, the outer surface of the roller 6 is fitted with a silicone rubber sleeve, the inside of the liquid injection tank 14 is connected to the input end of the high pressure nozzle 16 through the connecting pipe 15, and the output end of the high pressure nozzle 16 extends to the outer surface of the rotating plate 10.

[0034] In this embodiment, the feed pipe 2 is connected to the connecting groove 7 to ensure that the cleaning fluid can smoothly enter the internal structure of the device. The silicone rubber sleeve outside the roller 6 increases the friction between the roller 6 and the inner wall of the pipe, ensuring that the fixed seat 1 is stably located in the center of the pipe during the cleaning process, and also avoids the roller 6 from causing scratch damage to the inner wall of the pipe. The connection structure of the injection tank 14, the connecting pipe 15 and the high-pressure nozzle 16 ensures that the cleaning fluid can be accurately sprayed from the high-pressure nozzle 16 onto the inner wall of the pipe, and the output end of the high-pressure nozzle 16 extends to the outer surface of the rotating plate 10, so that the cleaning fluid can directly act on the inner wall of the pipe to achieve efficient cleaning.

[0035] The working principle and usage process of this utility model are as follows: During use, hold the pipe connected to the feed pipe 2 and place it against the inner wall of the intercooler pipe of the fixed seat 1. After starting the high-pressure water pump, xylene liquid is drawn into the feed pipe 2 and enters the liquid passage 8. At this time, the hydraulic pressure inside the liquid passage 8 increases, and the xylene liquid enters the sliding groove 3, driving the sealing plate 4 to slide. The sealing plate 4 drives the connecting plate 5 and roller 6 to slide against the inner wall of the pipe until the outer surface of the roller 6 abuts against the inner wall of the pipe. At this point, stop applying external force to the fixed seat 1. The fixed seat 1 will be at the center of the pipe, and the flow of liquid inside the liquid passage 8 will drive the impeller 94 to rotate. 4. The fixed plate 13 is rotated by the rotating shaft 93. The fixed plate 13 drives the rotating plate 10 to rotate through the fixed rod 12. At the same time, the liquid inside the liquid tank 8 passes through the liquid inlet tank 11 and enters the liquid injection tank 14. Then, it enters the high-pressure nozzle 16 through the connecting pipe 15 and is sprayed onto the inner wall of the pipe to clean the inner wall of the pipe. At the same time, with the rotation of the rotating plate 10 and the pipe connected to the feed pipe 2 by hand, the fixed seat 1 is moved as a whole to achieve all-round cleaning of the inner wall of the pipe. The roller 6 abuts against the inner wall of the pipe, which can not only ensure that the fixed seat 1 is located in the center of the pipe, but also facilitate the movement of the fixed seat 1 inside the pipe, thus enhancing its practicality.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
