Description

Technical Field

[0001] This invention relates to the field of container maintenance technology, and in particular to a device and method for curing and repairing anti-corrosion coatings on tank containers. Background Technology

[0002] Tank containers, as a standardized transportation equipment, are widely used in the petrochemical and fine chemical industries to transport high-purity, highly corrosive chemicals and other media. The anti-corrosion coating is the core protective structure that ensures the inner wall of the tank container is not corroded by the media and extends the service life of the tank. However, during long-term loading and unloading, transportation bumps, and routine maintenance, the anti-corrosion coating on the inner wall of tank containers is prone to scratches, wear, and peeling. Once the anti-corrosion coating fails, the tank substrate may be corroded by the transported media, leading to leakage risks and significantly shortening the service life of the tank container. Therefore, timely and efficient repair of damaged anti-corrosion coatings is crucial.

[0003] Currently, there are two main solutions for repairing damaged anti-corrosion coatings on tank containers in the industry, but both have significant technical defects and cannot meet the needs of efficient, accurate and low-cost repair in practical applications.

[0004] One solution is to transport the damaged tank back to the factory as a whole and heat the entire tank uniformly in a large oven to cure the anti-corrosion coating repair material. However, since tank containers are standard international-sized equipment, they are large and heavy, and transporting them to the factory would incur high transportation costs. Furthermore, it is difficult to precisely control the temperature uniformity during the overall heating process, which could potentially affect the performance of the original anti-corrosion coating on undamaged areas of the tank.

[0005] Another approach is to use an on-site emergency repair kit, employing simple heating tools such as a hot air gun for localized heating and repair. While this solution addresses the issue of transporting the tank back and forth, it suffers from fatal technical shortcomings. The hot air gun's heating method is a non-contact, crude heating approach, unable to achieve precise temperature control of the repair area. Excessive heating can lead to aging and cracking of the repair coating, while insufficient temperature results in incomplete curing of the repair material. Furthermore, the hot air gun's heating uniformity is extremely poor, with significant temperature differences across different areas of the repair zone. This leads to insufficient adhesion between the repair coating and the tank substrate, significantly reducing corrosion resistance. The repaired coating is prone to peeling off again, failing to achieve long-term stable corrosion protection. It can only serve as a temporary emergency measure and is insufficient to meet industrial-grade repair quality requirements.

[0006] Therefore, there is an urgent need to design a technical solution that can achieve precise local heating, eliminate the need for overall transportation, be easy to operate, and provide stable repair quality. Summary of the Invention

[0007] The purpose of this invention is to provide a device and method for curing and repairing anti-corrosion coatings on tank containers, so as to solve the problems existing in the prior art. It can achieve localized precise heating, eliminate the need for overall transportation, facilitate operation, and ensure stable repair quality.

[0008] To achieve the above objectives, the present invention provides the following solution: This invention provides a device for curing and repairing anti-corrosion coatings on tank containers, comprising: An adsorption heating device is capable of adsorbing and fixing onto the side wall adjacent to the container repair area to heat and solidify the repair area and collect temperature data of the repair area; and a handheld control device is electrically and pneumatically connected to the adsorption heating device to control the adsorption process of the adsorption heating device and receive the collected temperature data to regulate the heating process and heating temperature of the adsorption heating device.

[0009] In one embodiment, the adsorption heating device includes: shell; An induction heating unit, located inside the outer casing, is capable of generating an alternating magnetic field, causing the wall of the tank to be repaired to directly heat up. A mica sheet is fixedly fitted into a through hole at one end of the outer shell, with its inner side in contact with the induction heating unit and its outer side able to be in contact with the repair area to protect the induction heating unit. A vacuum adsorption unit is fixedly disposed inside the outer shell. It includes multiple flexible vacuum suction cups, each of which is fitted one-to-one with multiple adsorption holes opened at one end of the outer shell. The diameter of the flexible vacuum suction cup is larger than the diameter of the adsorption hole. The adsorption holes and the mica sheet are located at the same end of the outer shell, and the multiple adsorption holes are arranged around the outside of the mica sheet. A temperature measuring device is located inside the housing to perform non-contact infrared temperature measurement on the repair area through an infrared temperature measuring hole on the housing.

[0010] In one embodiment, the outer shell has an opening at one end, and a base plate is fixedly provided at the opening end. A handle is provided on the outer side of the base plate. The induction heating unit, the vacuum adsorption unit, and the temperature measuring device are all located in the cavity formed by the outer shell and the base plate. The end of the outer shell away from the base plate is an insulating plate, and the through hole and the adsorption hole are both opened on the insulating plate.

[0011] In one embodiment, a support plate is provided inside the outer shell. One side of the support plate is fixedly connected to the inner side of the base plate via a column, and the induction heating unit, vacuum adsorption unit, and temperature measuring device are fixedly provided on the other side of the support plate.

[0012] In one embodiment, the induction heating unit includes: The induction coil assembly is mounted on the support plate around its perimeter by columns and fasteners, and its upper surface is attached to the lower surface of the mica sheet. The induction coil assembly is electrically connected to the main control module in the portable fixing device. Magnetic strips are evenly distributed at the bottom of the induction coil assembly to reduce magnetic resistance, act as a shield, and prevent leakage of alternating magnetic field.

[0013] In one embodiment, the vacuum adsorption unit includes a vacuum suction cup fixed to the support plate by a column. The vacuum suction cup has a vacuum suction port coaxial with the corresponding adsorption hole. The vacuum suction port is connected to the vacuum diaphragm pump assembly in the handheld control device through an air pipe.

[0014] In one embodiment, the temperature measuring device includes an infrared probe fixedly mounted on the support plate. The infrared probe can directly measure the surface temperature of the heated area through a temperature measuring hole on the insulating plate. The infrared probe is connected to the main control module in the portable fixed device via a wire.

[0015] In one embodiment, the handheld control device includes: The casing has a gripping part on its outer side; The main control module is located inside the housing and is connected to the human-machine interface, heat dissipation components, temperature measuring device and power supply components respectively.

The handheld control device regulates the heating process of the adsorption heating device based on the collected temperature values.

[0017] In one embodiment, the step of adjusting the heating process of the adsorption heating device based on the collected temperature values ​​includes: A heating control curve is generated based on the process requirements for curing the anti-corrosion coating. This curve is then used to control the heating process, including rapid or slow heating, step-by-step heating, and heat preservation. Simultaneously, the heating process data is recorded and saved in real time, generating a heating curve. All data is traceable and exportable. The main control module within the portable control device, based on the preset heating control curve, dynamically adjusts the power output to the induction heating unit using a closed-loop control algorithm by comparing the temperature feedback value collected by the infrared probe with the target setpoint in real time. This ensures accurate output heating power from the induction heating unit, guaranteeing temperature stability during heating and heat preservation processes and preventing anti-corrosion coating curing failure caused by abnormal temperature fluctuations.

[0018] When the temperature value is lower than the set temperature, the heating power can be increased in a controllable manner; When the temperature value is higher than the set temperature, the heating power can be controlled to decrease until heating stops.

[0019] The present invention achieves the following technical effects compared to the prior art: This invention relates to an adsorption heating device that can be adsorbed and fixed onto the side wall adjacent to the container repair area using a flexible vacuum suction cup. The flexible design adapts to the curvature of the tank wall, ensuring reliable adsorption of the heating unit and thus guaranteeing uniform temperature throughout the curing process. The device heats and cures the repair area and collects temperature data. A portable control device, electrically and pneumatically connected to the adsorption heating device, controls the adsorption process and receives the collected temperature data. A closed-loop control algorithm precisely regulates the heating process and temperature, enabling localized and controllable heating of the anti-corrosion layer on the damaged inner wall of the tank. This ensures the anti-corrosion coating cures completely according to the heating process without manual intervention. Furthermore, the device stores the data for later retrieval. It achieves precise localized heating, eliminates the need for overall transport, is easy to operate, and significantly improves repair quality and stability. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] The purpose of this invention is to provide a device and method for curing and repairing anti-corrosion coatings on tank containers, so as to solve the problems existing in the prior art. It can achieve localized precise heating, eliminate the need for overall transportation, facilitate operation, and ensure stable repair quality.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] One existing technology for curing and repairing anti-corrosion coatings on tank containers involves returning the entire tank to the factory for oven repair. This requires transporting the entire tank back to the factory, incurring high transportation costs. Furthermore, the oven repair process requires heating the entire tank, resulting in significant energy waste. Another existing technology involves using an emergency repair kit on-site, employing a hot air gun for heating and repair. However, due to limitations in achieving the required heating temperature and time, the anti-corrosion effect of the coating is difficult to meet practical needs. To address these issues, the first objective of this invention is to provide a device for curing and repairing anti-corrosion coatings on tank containers. Figures 1-7 As shown, the device includes an adsorption heating device 2 and a portable control device 1. The adsorption heating device 2 can be adsorbed and fixed on the side wall adjacent to the container repair area to heat and solidify the repair area and collect the temperature value of the repair area. The portable control device 1 is electrically and pneumatically connected to the adsorption heating device 2 and is used to control the adsorption process of the adsorption heating device 2 and receive the collected temperature value to regulate the heating process and heating temperature of the adsorption heating device 2. The present invention employs an adsorption heating device 2, which is fixed to the side wall adjacent to the container repair area to heat and solidify the repair area and collect temperature data. A portable control device 1 is electrically connected to the adsorption heating device 2, and the vacuum pump of the portable control device 1 is air-connected to the flexible suction cup of the adsorption heating device 2 through an air pipe. This allows the device to control the adsorption process of the adsorption heating device 2 and receive the collected temperature data to regulate the heating process and temperature of the adsorption heating device 2. This enables localized and controllable heating of the anti-corrosion layer on the damaged inner wall of the container, ensuring that the anti-corrosion coating can be completely solidified according to the heating process without additional manual intervention. Furthermore, the device can store the data of the entire process, which can be retrieved at any time for review. This invention achieves precise localized heating, eliminates the need for overall transportation, is convenient to operate, and improves the quality of repair.

[0027] In one embodiment, the adsorption heating device 2 includes a shell, an induction heating unit, a mica sheet 207, a vacuum adsorption unit 203, and a temperature measuring device. One end of the shell is open, and a base plate 210 is fixedly provided at the open end. A handle 209 is provided on the outside of the base plate 210. A support plate 204 is provided inside the shell. One side of the support plate 204 is fixedly connected to the inside of the base plate 210 through a column 201. The induction heating unit, the vacuum adsorption unit 203, and the temperature measuring device are fixedly provided on the other side of the support plate 204. The end of the shell away from the base plate 210 is an insulating plate 208. Through holes and adsorption holes are opened on the insulating plate 208. Since the induction heating unit can generate an alternating magnetic field, causing the wall of the tank to be repaired to heat up directly, the insulating plate 208 can avoid interfering with the working process of the induction heating unit.

[0028] In one embodiment, the induction heating unit can generate an alternating magnetic field, causing the tank wall to be repaired to heat up directly. It includes an induction coil assembly 202 and a magnetic strip 205. The induction coil assembly 202 is mounted on a support plate 204 around its perimeter by columns 201 and fasteners, and its upper surface is attached to the lower surface of a mica sheet 207. The induction coil assembly 202 is electrically connected to the main control module 102 in the portable fixing device. The magnetic strip 205 is evenly distributed at the bottom of the induction coil assembly 202 to reduce magnetic resistance, play a shielding role, and prevent leakage of the alternating magnetic field. After the induction coil assembly 202 is energized, the induction coil assembly 202 itself does not heat up, but only generates a high-frequency alternating magnetic field, which heats up the tank wall through spatial coupling. The mica sheet 207 is fixedly fitted into the through hole at one end of the housing. Its inner side is in contact with the induction heating unit, and its outer side can be in contact with the repair area. The mica sheet 207 is used to protect the induction coil assembly 202 of the induction heating unit and prevent metal or other conductive materials from acting on the induction coil assembly 202 and causing damage to the induction coil assembly 202.

[0029] In one embodiment, the vacuum adsorption unit 203 is fixedly disposed inside the outer shell. It includes multiple flexible vacuum suction cups, each of which corresponds to and is fitted with multiple adsorption holes opened at one end of the outer shell. The diameter of the flexible vacuum suction cup is larger than the diameter of the adsorption hole. In this embodiment, the flexible vacuum suction cup is a sponge suction cup, with a vacuum suction port coaxial with the corresponding adsorption hole at its center. The vacuum suction port is connected to the vacuum diaphragm pump assembly 103 in the portable control device 1 through the air pipe 4. The vacuum diaphragm pump assembly 103 can continuously draw a vacuum, thereby causing the vacuum suction cup to be vacuum adsorbed onto the side wall of the tank through the adsorption hole. The adsorption hole and the mica sheet 207 are located at the same end of the outer shell, and the multiple adsorption holes are arranged in a ring around the mica sheet. The outer side of the plate 207 ensures that the vacuum adsorption position is located outside the repair area, thus not interfering with the heating and curing of the repair area. The flexible vacuum suction cup can be firmly fixed according to the surface position around the repair point, so that the heating center is aligned with the vicinity of the anti-corrosion coating repair point for constant temperature heating, thereby meeting the requirements of anti-corrosion coating curing and repair. The temperature measuring device is located inside the housing, including an infrared probe 206 fixed on the support plate 204. The infrared probe 206 can non-contactly measure the surface temperature of the heated area through the temperature measuring hole on the insulating plate 208. The infrared probe 206 is connected to the main control module 102 in the portable fixed device through a wire, and can transmit the measured temperature to the main control module 102.

[0030] In one embodiment, the portable control device 1 includes a housing 101, a main control module 102, a vacuum diaphragm pump assembly 103, and an impedance matching module unit 105. The housing 101 has a grip on its outer side for easy carrying by the operator. The main control module 102 is located inside the housing 101 and is connected to a human-machine interface 106, a heat dissipation assembly 107, a temperature measuring device, and a power supply assembly 104. A heat dissipation hole is provided on one side of the housing 101. The heat dissipation assembly 107 is a cooling fan installed in the heat dissipation hole to dissipate heat from the inside of the housing 101. The vacuum diaphragm pump assembly 103 is connected to the vacuum adsorption unit 203 through an air pipe 4 and is communicatively connected to the main control module 102. The induction heating unit is connected to the impedance matching module unit 105 through a wire, and the impedance matching module unit 105 is connected to the main control module 102.

[0031] The portable control device 1 uses a main control module 102 as its central control unit. It connects to the human-machine interface 106 via a ribbon cable for communication. The operating parameters of the main control module 102 can be displayed on the human-machine interface, and control commands from the human-machine interface can be read to adjust the operating mode of the main control module 102. During operation, the main control module 102 requires heat dissipation, which is handled by a heat dissipation module under the control of the main control module 102. The main control module 102 reads signals from the vacuum control switch, and relays on the main control module 102 control the start and stop of the vacuum diaphragm pump assembly 103.

[0032] The air tube 4, induction heating unit, and infrared probe 206 of the adsorption heating device 2 are connected to the corresponding interface of the portable control device 1 via their respective leads. Correspondingly, the induction heating unit lead is connected to the high-voltage output terminal of the main control module 102 via a quick-connect interface to heat the repair point; the air tube 4 is connected to the vacuum diaphragm pump assembly 103 via a dedicated air tube connector to create a vacuum state for adsorption; the infrared probe 206 is connected to the main control module 102 via a dedicated signal connector, and is sampled by the dedicated signal acquisition circuit on the main control module 102 for temperature control.

[0033] The HMI (Human Machine Interface) allows for the customization and storage of over 20 repair processes. Each process can have up to 50 process control nodes, each with its own set heating temperature and time. The HMI stores the central process flow and parameters for later retrieval depending on the specific repair needs. The HMI displays and records temperature and time data and curves in real time, and supports real-time data playback and export when necessary.

[0034] In one embodiment, the main control module 102 further includes temperature measurement calibration and fault alarm functions, as detailed below: The control unit supports temperature calibration to ensure more accurate temperature measurement and control under different environmental conditions. Calibration process: Infrared temperature sensors have measurement errors. Through the probe calibration interface on the human-machine interface 106, the probe is placed in a standard environment (100 degrees Celsius). By adjusting the calibration value, the probe can accurately indicate the temperature value.

[0035] Fault Alarm: The system supports unattended operation and can run automatically after selecting the process flow without human supervision. If a fault occurs or manual intervention is required, the control host can call for help via sound alarm. During operation, the main control module 102 continuously monitors the working status of each unit, such as vacuum degree, temperature, and voltage, and compares them with their internal reference values. When these values ​​exceed their set range, an abnormality is considered, and an audible and visual alarm is triggered through the human-machine interface 106 to prompt the operator to handle the situation. At the same time, this alarm information is also saved to the internal storage unit for later retrieval.

[0036] In using this invention, the underlying anti-corrosion material at the area requiring repair is first cleaned by grinding, and then repair material is applied. Next, the center of the adsorption heating device 2 is aligned with the repair area. The vacuum diaphragm pump inside the portable control device 1 is activated via a control switch. This pump, through the air pipe 4, creates a vacuum between the vacuum suction cup and the inner wall of the tank, allowing the adsorption heating device 2 to be fixed in the required position. The induction heating unit is securely connected to the portable control device 1 via cable 3. The lead wire of the temperature measuring device is securely connected to the sensor interface of the power generator. Through the human-machine interface 106, the repair program is selected, and the switch button is pressed to begin controllable heating of the repair point. Simultaneously, temperature data from the infrared probe 206 is collected and compared with the temperature set in the selected repair program. Heating begins when the collected temperature is lower than the set temperature; heating stops when the collected temperature is higher than the set temperature, ensuring temperature control. The repair procedure, according to industrial requirements, can be divided into multiple stages. Each stage includes setting a temperature and a set duration. The main control module 102 controls the heating temperature and time required for each stage based on these parameters, ensuring uniform heating and controllable temperature rise at the repair point. When the main control module 102 completes the selected repair procedure, it stops heating and prompts the user through the human-machine interface that the operation is complete. By turning off the vacuum diaphragm pump in the portable control device 1 via the control switch, the vacuum adsorption unit 203 can be removed. After the above process, the repair of the anti-corrosion coating of the tank container is completed.

[0037] Based on the above-mentioned equipment for curing and repairing anti-corrosion coatings of tank containers, the present invention also provides a method for curing and repairing anti-corrosion coatings of tank containers, comprising the following steps: The adsorption heating device is adsorbed and fixed to the side wall adjacent to the container tank repair area; The adsorption heating device is controlled to heat and solidify the repair area, and the temperature value of the repair area is collected by the temperature measuring device. The handheld control device regulates the heating process of the adsorption heating device based on the collected temperature values.

[0038] Specifically, a heating control curve is generated based on the process requirements for curing the anti-corrosion coating, and rapid or slow heating, step-by-step heating, and heat preservation are controlled according to the heating control curve. Simultaneously, the heating process data is recorded and saved in real time, generating a heating curve, and all data can be traced and exported. The main control module in the portable control device, based on the preset heating control curve, dynamically adjusts the power output to the induction heating unit by comparing the temperature feedback value collected by the infrared probe with the target set value in real time, using a closed-loop control algorithm (such as PID control). This ensures temperature stability during the heating and heat preservation processes, preventing anti-corrosion coating curing failure caused by abnormal temperature fluctuations. When the temperature is lower than the set temperature, the heating power is controllably increased; when the temperature is higher than the set temperature, the heating power is controllably decreased until heating stops.

[0039] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
