The sandblasting working area 7 is located between the steel shot supply area 6 and the hoisting device assembly 10, and is used to treat carbon deposits on the surface of the turbocharger exhaust impeller.

[0006] The steel shot feeding area 6 includes an air compressor unit 6a, an air storage tank 6b, an air filter 6c, a steel shot silo 6d, an air dryer 6e, and a power distribution box 6f.

The base of the sandblasting robotic arm 22 and the sandblasting processing work area monitoring camera 21 are fixed inside the upper part of the sandblasting work area housing 7a. The sandblasting robotic arm 22 consists of a steel sand spray gun 22a and a robotic arm 22b. The steel sand spray gun 22a is connected to an air inlet pipe 6h and a steel sand inlet pipe 6i. The robotic arm 22b is used to control the steel sand spray gun 22a to sandblast the carbon deposits on the turbocharger exhaust impeller 9c.

[0008] The roller shutter door device 8 includes a roller shutter door motor 8a and a roller shutter door cover 8b. The roller shutter door device 8 is located above the doorway of the sandblasting work area box 7a. When the sandblasting work area 7 starts sandblasting, the roller shutter door motor 8a controls the roller shutter door to descend, thereby enabling the sandblasting work area 7 to work normally.

[0009] The turbocharger impeller mounting device 9 includes a turbocharger impeller mounting platform track 9a, a turbocharger compressor impeller 9b, a turbocharger exhaust impeller 9c, a rotary table drive motor 9d, a rotary table mounting platform 9e, a rotary table 9f, a left rotary table drive motor set 9g, and a right rotary table drive motor set 9h. The turbocharger impeller mounting device 9 is located on the sandblasting work platform 7b and is used to provide power to the turbocharger impeller mounting device 9.

[0010] The overall hoisting device 10 for transporting turbocharger impellers includes a left moving track 10a, a left moving device 10b of the gantry frame, a hoisting device 10c, a right moving device 10d of the gantry frame, and a right moving track 10e of the hoisting device. The overall hoisting device 10 is located in front of the sandblasting work area 7. The left moving device 10b of the gantry frame moves synchronously with the right moving device 10d of the gantry frame, driving the hoisting device 10c to move back and forth. The hoisting device 10c consists of a hoisting device support beam 15, a first hoisting device drive motor 16, a hoisting lifting motor 17, a second hoisting device drive motor 18, a steel rope 19, and a hook 20, and is used to hoist the turbocharger compressor impeller 9b and the turbocharger exhaust impeller 9c.

[0011] The steel shot secondary filtration device 4 includes an exhaust pipe 4a, a steel shot secondary filtration device motor 4b, and a steel shot secondary filtration device housing 4c. It is used to filter residual carbon deposits in the air after primary filtration. That is, the air after primary filtration enters the steel shot secondary filtration device housing 4c, is filtered by the steel shot secondary filtration device motor 4b, and then the treated air is discharged through the exhaust pipe 4a. At the same time, it utilizes both the primary filtration device and the secondary filtration device, that is, the steel shot in the flowing air is initially filtered, and then the steel shot secondary filtration device is used, which is connected to the steel shot primary filtration device, to perform secondary filtration on the pre-treated air to prevent air pollution.

[0012] The above-described intelligent workshop method for treating carbon deposits on the impeller of a ship's turbocharger exhaust gas using steel shot is characterized by the following steps: 1) Manual preparation steps: including starting the hoisting device, fixing the turbocharger impeller to the hook, operating the hoisting device to raise the hook, operating the left and right moving devices of the gantry frame to move the turbocharger impeller to the top of the rotary table, transferring the turbocharger impeller to the rotary table, removing the hoisting device, operating the rotary table platform to move to the designated position inside the cleaning work area, controlling the rotary table platform to stop at the appropriate position according to the monitoring camera of the cleaning work area, and operating the roller shutter door to lower the roller shutter door; 2) Turbocharger impeller cleaning steps: This includes starting the air compressor to use compressed air as the power source for sandblasting to remove carbon deposits. The air compressor compresses the air and stores it in an air tank to provide power for the sandblasting process. A primary steel grit filter is used to filter the collected air, removing carbon deposits and other impurities. A secondary steel grit filter is used, connected to the primary filter via its inlet pipe, to further filter the air after the primary filtration. Finally, the rotary table motor is started, and the turbocharger impeller mounting device moves the installed turbocharger impeller to the sandblasting position via two sets of rotary table drive motors. Inside the working area, the turbocharger impeller is rotated by a rotary table, allowing for more efficient and comprehensive treatment of carbon deposits on the turbocharger surface. The sandblasting robotic arm is activated, along with a steel shot blasting gun. The robotic arm simulates manual sandblasting, using the rotary table and the robotic arm to drive the steel shot blasting gun to sandblast the carbon deposits on the turbocharger exhaust impeller surface. This comprehensive sandblasting coverage allows for all-around coverage of the turbocharger exhaust impeller surface. The sandblasting robotic arm performs sandblasting according to a pre-set route and different sizes of exhaust impellers, while the steel shot blasting gun sandblasts the carbon deposits on the turbocharger exhaust impeller surface. A monitoring camera detects the cleanliness of the turbocharger impeller surface, and the sandblasting process is complete. 3) Manual termination steps: including operating the roller shutter door motor to raise the roller shutter door, operating the rotating turntable to move the platform to the cleaning work platform, operating the left and right moving devices of the gantry frame to move the hook to the top of the rotating turntable, transferring the turbocharger impeller to the hook, lowering the hoisting device, operating the left and right moving devices of the gantry frame to move the cleaning work platform away.

[0013] This invention proposes an intelligent workshop for treating carbon deposits on the exhaust impellers of marine turbochargers using steel shot. It employs an air compressor to inject air into an air storage tank, and maintains air cleanliness during operation through air filters and air dryers. A gantry structure is used as a hoisting device for the turbocharger impellers, overcoming their weight and achieving efficient and flexible movement. The hoisting device and accompanying traction provide enhanced safety and reliability. A turbocharger impeller mounting device allows for the movement of the impellers to a designated position within the sandblasting work area. A sandblasting robotic arm, utilizing a rotating turntable and a steel shot blasting gun, effectively sandblasts the carbon deposits on the surface of the turbocharger exhaust impellers, achieving comprehensive coverage. The surface of the turbocharger exhaust impeller is treated more comprehensively to remove carbon deposits, improving efficiency, by overcoming the limitations of different sizes of turbocharger exhaust impellers. A steel sand collecting funnel collects the treated steel sand into a steel sand collecting branch pipe, and then, under air pressure, it enters the primary steel sand filtration device through the main steel sand collecting pipe. Simultaneously utilizing both primary and secondary filtration devices, the steel sand in the flowing air undergoes initial filtration, followed by a secondary filtration connected to the primary device to further filter the pre-treated air, preventing air pollution. This significantly reduces air pollution and raises environmental awareness. Therefore, this method is safe, reliable, highly efficient, and easy to operate, making it highly valuable for engineering applications. Attached Figure Description

[0016] See reference Figure 1-18 These 18 figures illustrate the overall structure and operation of an intelligent workshop for treating carbon deposits on the impeller of a ship's turbocharger using steel shot, as proposed in this invention. (Combined with...) Figure 1-18 As shown, the present invention will be described in further detail below.

[0017] A smart workshop that uses steel shot to treat carbon deposits on the impellers of ship turbochargers, such as... Figure 1-13As shown, it includes an intelligent control platform 1, a sandblasting workshop fence 2, an intelligent working area 3 for treating the exhaust gas impeller of a marine turbocharger using steel shot, and a secondary steel shot filtration device 4. The intelligent control platform 1 and the secondary steel shot filtration device 4 are located on one side of the intelligent working area 3. The intelligent control platform allows for the overall control of the intelligent workshop for treating the exhaust gas impeller of the marine turbocharger using steel shot. The intelligent working area 3 is located inside the sandblasting workshop fence 2 to prevent unauthorized personnel from accidentally entering the area and causing injury. The intelligent control platform 1 controls the supply of steel shot, while the intelligent control platform 3 controls the supply of steel shot, the hoisting and movement of the turbocharger impeller, and the actions of the sandblasting robotic arm 22, achieving automated treatment of carbon deposits on the turbocharger exhaust gas impeller 9c. This method is safe, efficient, and highly intelligent.

[0018] The intelligent work area 3 includes a steel shot supply area 6, a sandblasting work area 7, a roller shutter door device 8, a turbocharger impeller mounting device 9, a turbocharger impeller hoisting assembly 10, and a steel shot primary filter device 11. The steel shot supply area 6 is located behind the sandblasting work area 7, providing sandblasting material and power. The roller shutter door device 8 is located above the sandblasting work area 7 to prevent environmental pollution during steel shot processing. The turbocharger impeller mounting device 9 is located on the platform of the sandblasting work area 7. The turbocharger impeller assembly 10 is located in front of the sandblasting work area 7. The turbocharger compressor impeller 9b and turbocharger exhaust impeller 9c are hoisted onto the rotary table 9f by the hoisting device assembly 10, and then moved into the sandblasting work area box 7a by the rotary table mounting platform 9e. This facilitates the handling of the turbocharger impellers, saves manpower, and improves efficiency. The sandblasting work area 7 is located between the steel grit feeding area 6 and the hoisting device assembly 10, and is used to treat the carbon deposits on the surface of the turbocharger exhaust impeller.

[0019] The turbocharger impeller mounting device 9 is located on the platform of the sandblasting work area 7; The steel shot supply area 6 includes an air compressor unit 6a, an air storage tank 6b, an air filter 6c, a steel shot silo 6d, an air dryer 6e, and a power distribution box 6f. After the power distribution box 6f is opened, the air compressor unit 6a starts to compress air and stores it in the air storage tank 6b. The compressed air passes through the air filter 6c and enters the air dryer 6e, and then enters the steel shot spray gun 22a on the sandblasting robotic arm 22. The compressed air drives the steel shot in the steel shot silo 6d to treat the carbon deposits on the turbocharger exhaust impeller 9c. Compressed air is used as the power source for sandblasting carbon deposits. The air compressor unit compresses the air and stores it in the air storage tank to provide the power source for sandblasting. The steel shot silo provides sandblasting material for sandblasting.

[0020] The sandblasting work area 7 includes a sandblasting work area housing 7a, a sandblasting work platform 7b, and a sandblasting robotic arm 22. The sandblasting robotic arm 22 is located inside the sandblasting work area housing 7a. The sandblasting work platform 7b, a sandblasting work area monitoring camera 21, a steel sand collecting funnel 23, and a steel sand collecting branch pipe 25 are also included. The base of the sandblasting robotic arm 22 and the sandblasting work area monitoring camera 21 are fixed to the upper part of the sandblasting work area housing 7a. The sandblasting robotic arm 22 consists of a steel sand spray gun 22a and the robotic arm 22b. The steel sand spray gun 22a is connected to the air inlet pipe 6h and the steel sand inlet pipe 6i. The robotic arm 22b controls the steel sand spray gun 22a to sandblast the carbon deposits on the turbocharger exhaust impeller 9c. Using a sandblasting robotic arm to simulate manual sandblasting allows for more flexible sandblasting operations. The steel sand spray gun is controlled to sandblast the carbon deposits on the surface of the turbocharger.

[0021] A monitoring camera is installed above the sandblasting work area chamber. Workers can observe the position of the turbocharger impeller and the sandblasting process on its side through this camera. Operators can observe the operation inside the sandblasting work area chamber 7a through the observation port 7c. A steel grit collecting funnel 23 and a steel grit collecting branch pipe 25 are located inside the sandblasting work area chamber 7a, collecting the treated steel grit. The steel grit collecting branch pipe 25 connects to the steel grit primary filter device 11 via the steel grit main pipe 24, which preliminarily filters out carbon deposits mixed within the steel grit.

[0022] The roller shutter door device 8 includes a roller shutter door motor 8a and a roller shutter door cover 8b. The roller shutter door device 8 is located above the entrance of the sandblasting work area housing 7a. When the sandblasting work area 7 begins sandblasting, the roller shutter door motor 8a controls the roller shutter door to descend, thus ensuring the normal operation of the sandblasting work area 7. By using the roller shutter door device, when the turbocharger impeller enters the sandblasting work area housing, the roller shutter door is lowered by the roller shutter door motor, preventing steel sand from spreading into the air, causing environmental pollution and harm to personnel, thus providing excellent protection.

[0023] Furthermore, the steel grit collecting funnel 23 and the steel grit collecting branch pipe 25 are located inside the sandblasting work area box 7a to collect the treated steel grit. The steel grit collecting branch pipe 25 is connected to the steel grit primary filter device 11 through the steel grit collecting main pipe 24 to initially filter the carbon deposits mixed in the steel grit. The steel grit collected by the steel grit collecting funnel is used to collect the sandblasted steel grit. Driven by air, the collected steel grit is passed through the steel grit collecting branch pipe, which can effectively collect the treated steel grit for secondary use.

[0024] Furthermore, the turbocharger impeller mounting device 9 is located on the sandblasting work platform 7b, and consists of the turbocharger impeller mounting platform track 9a, the turbocharger compressor impeller 9b, the turbocharger exhaust impeller 9c, the rotary table drive motor 9d, the rotary table mounting platform 9e, the rotary table 9f, the left rotary table drive motor set 9g, and the right rotary table drive motor set 9h. Since the composition and working principle of each drive device in the two sets of motors are the same, only one drive device will be described in detail here. It consists of the drive wheel 9i, the drive motor 9j, the drive motor mounting bracket 9k, and the driver 9m, which provides power to the turbocharger impeller mounting device 9. The turbocharger impeller mounting device is used to move the installed turbocharger impeller into the sandblasting work area by two sets of rotary table drive motors. At the same time, the turbocharger impeller is rotated by the rotary table, which can more efficiently and comprehensively treat the carbon deposits on the surface of the turbocharger. After the sandblasting work is completed, the turbocharger impeller is moved out onto the sandblasting work platform.

[0025] Furthermore, the overall assembly 10 for hoisting the turbocharger impeller is located in front of the sandblasting work area 7. It consists of a left-moving track 10a, a left-moving gantry 10b, a hoisting device 10c, a right-moving gantry 10d, and a right-moving track 10e. Since the two sets of gantry moving devices have the same composition and working principle, only one gantry moving device will be described in detail here. The left-moving gantry 10b consists of a left-moving support 13 and a left-moving motor 14. The left-moving gantry 10b moves synchronously with the right-moving gantry 10d, driving the hoisting device 10c to move back and forth. The hoisting device 10c consists of a hoisting device support beam 15, a first hoisting device drive motor 16, a hoisting lifting motor 17, a second hoisting device drive motor 18, a steel rope 19, and a hook 20. It is used to hoist the turbocharger compressor impeller 9b and the turbocharger exhaust impeller 9c, which can improve the handling efficiency and prevent personnel injury. The hoisting device and gantry crane are used as carriers to transport the turbocharger impeller to the turbocharger impeller mounting device. After the sandblasting work is completed, the turbocharger impeller is hoisted to the ground.

[0026] Furthermore, the steel sand secondary filter 4 is located on one side of the steel sand primary filter 11. The primary filter is used to perform primary filtration on the collected air, filtering out carbon deposits and other impurities in the flowing air. It is connected to the steel sand secondary filter inlet pipe 12. The steel sand secondary filter, connected to the steel sand primary filter through the steel sand secondary filter inlet pipe, performs secondary filtration on the air after primary filtration, which can better and more effectively reduce carbon deposits and impurities in the air.

[0027] The steel grit secondary filtration device 4 consists of an exhaust pipe 4a, a steel grit secondary filtration device motor 4b, and a steel grit secondary filtration device housing 4c. After the air is filtered by the steel grit primary filtration device 11, there is some residual carbon deposit. The steel grit secondary filtration device motor 4b drives the air filtered by the steel grit primary filtration device 11 into the steel grit secondary filtration device housing 4c. After filtration, the treated air is discharged through the exhaust pipe 4a.

[0028] The above-described intelligent workshop method for treating carbon deposits on the impeller of a ship's turbocharger using steel shot is characterized by the following steps: 1) Manual preparation steps: including starting the hoisting device, fixing the turbocharger impeller to the hook, operating the hoisting device to raise the hook, operating the left and right moving devices of the gantry frame to move the turbocharger impeller to the top of the rotary table, transferring the turbocharger impeller to the rotary table, removing the hoisting device, operating the rotary table platform to move to the designated position inside the cleaning work area, controlling the rotary table platform to stop at the appropriate position according to the monitoring camera of the cleaning work area, and operating the roller shutter door to lower the roller shutter door; 2) Turbocharger impeller cleaning steps: This includes starting the air compressor to use compressed air as the power source for sandblasting to remove carbon deposits. The air compressor compresses the air and stores it in an air tank to provide power for the sandblasting process. A primary steel grit filter is used to filter the collected air, removing carbon deposits and other impurities. A secondary steel grit filter is used, connected to the primary filter via its inlet pipe, to further filter the air after the primary filtration. Finally, the rotary turntable motor is started, and the turbocharger impeller mounting device is used to mount the installed... The turbocharger impeller is driven by two sets of rotary table drive motors to move the rotary table into the sandblasting work area. At the same time, the rotary table rotates the turbocharger impeller, which can more efficiently and comprehensively treat the carbon deposits on the surface of the turbocharger. Simultaneously, the sandblasting robotic arm is activated, and the steel shot blasting gun is started. The sandblasting robotic arm simulates manual sandblasting. The sandblasting robotic arm performs sandblasting according to the set route and different sizes of exhaust gas impellers. The steel shot blasting gun sandblasts the carbon deposits on the surface of the turbocharger exhaust gas impeller. The cleanliness of the turbocharger impeller surface is detected by a monitoring camera. The sandblasting process is then completed. 3) Manual termination steps: including operating the roller shutter door motor to raise the roller shutter door, operating the rotating turntable to move the platform to the cleaning work platform, operating the left and right moving devices of the gantry frame to move the hook to the top of the rotating turntable, transferring the turbocharger impeller to the hook, lowering the hoisting device, operating the left and right moving devices of the gantry frame to move the cleaning work platform away.

[0029] In use, the turbocharger impeller is first fixed to the hook of the hoisting device. The gantry and hoisting device are then controlled by the intelligent control platform to move the turbocharger impeller. The impeller is then manually fixed to the rotating turntable. The intelligent control platform then controls the turbocharger impeller to move the platform to the sandblasting work area and start the roller shutter door.

[0030] After filling the steel grit bin with steel grit, start the air compressor, dryer, sandblasting robotic arm, primary steel grit filter, and secondary steel grit filter. Once the sandblasting is complete, start the roller shutter door device. The intelligent control platform will then control the turbocharger impeller to move the platform to the sandblasting work platform. Press the pause button.

[0031] The main control system of this equipment includes: steel grit feeding system, sandblasting robotic arm, primary steel grit filtration device, secondary steel grit filtration device, and other systems such as the mobile power system, which only control the position of the gantry, hoisting device, and turbocharger impeller mounting platform.

[0032] After receiving the start signal, the system activates the power signal of the steel grit feeding system, and the air compressor and dryer begin to work. Once the required pressure is reached in the air tank, the start signals for the sandblasting robotic arm, the primary steel grit filter, and the secondary steel grit filter are simultaneously activated. The operator adjusts the sandblasting path of the robotic arm according to the different sizes of the turbocharger's exhaust impeller, and at the same time, the start signal for the rotary table is activated, rotating the turbocharger impeller to achieve better sandblasting results and higher efficiency. The complete and detailed process is as follows: Figure 16 As shown.

[0033] The present invention proposes an intelligent workshop and its working method for treating carbon deposits on the exhaust impeller of a marine turbocharger using steel shot. This workshop can efficiently and conveniently perform one-time sandblasting treatment on the surface carbon deposits of the exhaust impeller of a marine turbocharger. It fully considers the requirements of practical engineering applications and economic efficiency, has complete functions, is easy to operate, and can be applied to exhaust impellers of marine turbochargers of various sizes. Compressed air is used as the power source for sandblasting to remove carbon deposits. An air compressor compresses the air and stores it in an air tank, providing power for the sandblasting process, ensuring safety, environmental friendliness, and high efficiency. A hoisting device and gantry crane are used as carriers to transport the turbocharger impeller to a mounting device. After sandblasting, the impeller is then hoisted back to the ground, improving the efficiency of installation and transport. The mounting device moves the installed impeller into the sandblasting work area via two sets of rotary table drive motors. Simultaneously, the rotary table rotates the impeller, allowing for comprehensive, all-around sandblasting of the impeller surface, improving the quality of the sandblasting effect. A robotic arm simulates manual sandblasting, allowing for more flexible sandblasting operations and handling turbochargers of different sizes. The turbocharger exhaust impeller is meticulously designed to reach every corner of the impeller surface, enhancing sandblasting flexibility and quality. A roller shutter door prevents steel shot from scattering into the air during sandblasting, thus avoiding environmental pollution and potential harm to personnel. A monitoring camera is installed above the sandblasting work area, allowing staff to observe the location of the turbocharger exhaust impeller and the sandblasting process in real time. A steel shot collection funnel collects the sandblasted steel shot for reuse. A primary steel shot filtration system filters the collected air, followed by a secondary steel shot filtration system to further reduce carbon deposits. An intelligent control platform manages the entire steel shot processing workshop, making sandblasting efficient, convenient, and intelligent.

[0034] It should be understood that the above-described embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
