Description

Technical Field

[0001] This utility model relates to the field of electron accelerator auxiliary equipment technology, and in particular to an automatic cleaning device for titanium foil under an electron accelerator beam. Background Technology

[0002] Industrial electron accelerators have been successfully applied in multiple fields and scenarios, such as irradiation modification, sterilization, preservation, and nuclear environmental protection. Irradiation modification is used in applications involving wires and cables, heat-shrinkable materials, polymers, electronic components, and semiconductors. Sterilization is used in medical devices, pet food, medical dressings, toys and supplies, traditional Chinese medicine, Western medicine, health products, cosmetics, and other daily necessities. Preservation is used for quarantine processing, fresh vegetables, frozen foods, snack foods, health foods, grain preservation, emergency relief food, and alcoholic beverages. Nuclear environmental protection is used for wastewater, waste gas, and solid waste. However, in these applications, titanium foil, as a key component of the scanning window under the accelerator beam, is continuously subjected to multiple forms of damage, including radiation, humidity, and ozone corrosion. Radiation damages the microstructure of titanium foil, reducing its physical properties; humid environments easily cause water droplets to form on the surface of the titanium foil, increasing the risk of corrosion; and ozone, with its strong oxidizing properties, accelerates the corrosion process of the titanium foil. These factors make it extremely easy for impurities such as water droplets and dust to adhere to the surface of titanium foil, which not only shortens the service life of titanium foil, but also seriously affects the irradiation effect of electron accelerators and reduces the equipment's processing capacity.

[0003] Currently, titanium foil cleaning mainly relies on manual operation. Before each cleaning, the accelerator must be stopped, and the irradiation chamber must be ventilated for an extended period until the radiation and ozone concentrations drop to safe levels. Only after the instruments have confirmed safety can staff enter the irradiation chamber to clean the titanium foil. However, this cleaning method has many drawbacks: frequent cleaning consumes a lot of manpower and time, reducing production efficiency; staff are exposed to radiation risks for extended periods, and even with protective measures, they may still suffer radiation hazards and damage their health; the quality of manual cleaning is affected by the operator's skills and working conditions, making it difficult to guarantee consistent cleaning results each time, which is detrimental to the stable operation of the equipment.

[0004] However, existing automated cleaning devices are insufficient to meet the specific requirements of cleaning titanium foil under electron accelerator beams. Regarding ionizing radiation technology, a patent for an automated cleaning device and method for radioactive source components (CN114713560 A) provides an automated control system that combines a cleaning solution with an ultrasonic cleaning assembly for component cleaning. However, the cleaning solution and ultrasonic device required by this patent are highly susceptible to damage in the radiation environment of an electron accelerator beam, making it unsuitable for cleaning titanium foil under electron beam accelerators. Furthermore, electron accelerators are commonly used in material modification, sterilization, and environmental protection, especially in wastewater treatment. In this scenario, wastewater is irradiated, and the purpose of automated cleaning is to remove water droplets, dust, and other impurities adhering to the surface of the titanium foil. Other patents involving automated cleaning devices primarily use cleaning solutions, which are unsuitable for use under electron accelerator beams due to the highly damaging environment.

[0005] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this application. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide an automatic cleaning device for titanium foil under an electron accelerator beam.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] An automatic cleaning device for titanium foil under an electron accelerator beam includes a guiding mechanism and a titanium foil roll mounted on the guiding mechanism. A titanium foil extending from the titanium foil roll is disposed on the guiding mechanism. A cleaning mechanism is installed at the titanium foil roll and acts on the titanium foil. The titanium foil roll is connected to a driving mechanism, which drives the titanium foil roll to rotate alternately to move the titanium foil reciprocally along the guiding mechanism.

[0009] The drive mechanism is electrically connected to the automatic control system.

[0010] Furthermore, the guiding mechanism includes a first titanium foil guide rail and a second titanium foil guide rail arranged symmetrically, with a gap between the first titanium foil guide rail and the second titanium foil guide rail to accommodate the titanium foil.

[0011] Furthermore, both the first titanium foil guide rail and the second titanium foil guide rail are double-layer titanium foil guide rails.

[0012] Furthermore, the titanium foil rolls are installed at both ends of the first and second titanium foil guide rails along their length.

[0013] Furthermore, the cleaning mechanism includes a cleaning scraper.

[0014] Furthermore, the drive structure includes a first pneumatic motor and a second pneumatic motor, which are respectively driven connected to the two titanium foil rolls.

[0015] Furthermore, the length of the titanium foil is twice the length of the first titanium foil guide rail and the second titanium foil guide rail.

[0016] Furthermore, the first titanium foil guide rail, the second titanium foil guide rail, and the cleaning scraper are all made of radiation-resistant and corrosion-resistant materials.

[0017] Furthermore, the first pneumatic motor and the second pneumatic motor are equipped with radiation protection shields.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. Improved cleaning efficiency: Through the combined use of the cleaning scraper and the automatic control system, the cleaning scraper structure can clean water droplets and impurities on the titanium foil, while the automatic control system can realize automatic cleaning of the titanium foil and can operate without stopping the electron accelerator. Compared with the traditional manual cleaning method, it greatly reduces the cleaning time and improves the operating efficiency of the equipment.

[0020] 2. Ensure personnel safety: Reduces the number of times staff enter the radiation environment, thus reducing the harm of radiation to the health of staff.

[0021] 3. Extended equipment lifespan: The key components of the device have been specifically designed to address the unique environment of the electron accelerator beam. For example, the lead glass cover on the pneumatic motor effectively prevents radiation damage, and the stainless steel scrapers and guide rails offer excellent corrosion resistance. This ensures stable operation of the entire cleaning system in harsh environments, extending its lifespan. Attached Figure Description

[0026] The technical solution of this utility model will now be clearly and completely described through specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. 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.

[0027] See appendix Figure 1 As shown, this application discloses an automatic titanium foil cleaning device under an electron accelerator beam, aiming to solve the problems existing in the titanium foil cleaning methods of the prior art. By designing an automated cleaning device, the frequency of manual cleaning is reduced, the exposure risk of workers in the radiation environment is lowered, and the health of workers is protected. At the same time, efficient cleaning of titanium foil is achieved, ensuring the irradiation effect of the electron accelerator, improving the overall operating efficiency of the equipment, and extending the service life of the equipment. This application includes a guiding mechanism and a titanium foil roll 1 mounted on the guiding mechanism. Titanium foil 2 extending from the titanium foil roll 1 is disposed on the guiding mechanism. A cleaning mechanism is installed at the titanium foil roll 1, and the cleaning mechanism acts on the titanium foil 2. The titanium foil roll 1 is connected to a driving mechanism, which drives the titanium foil roll 1 to rotate alternately to drive the titanium foil 2 to reciprocate along the guiding mechanism. The driving mechanism is electrically connected to an automatic control system.

[0028] The following provides further explanation of the above structure:

[0029] See appendix Figure 1 As shown, the guiding mechanism includes a symmetrically arranged first titanium foil guide rail 3 and second titanium foil guide rail 4. Both the first titanium foil guide rail 3 and the second titanium foil guide rail 4 have a two-layer structure with a gap in the middle. The first titanium foil guide rail 3 and the second titanium foil guide rail 4 provide a stable running track for the titanium foil 2, allowing it to move smoothly within the first titanium foil guide rail 3 and the second titanium foil guide rail 4, reducing the problem of poor cleaning effect caused by shaking or deviation. The first titanium foil guide rail 3 and the second titanium foil guide rail 4 are both made of stainless steel. Stainless steel has good corrosion resistance and can adapt to the harsh environment of radiation, humidity, and corrosion under electron accelerator beams, extending the service life of the guide rails. Preferably, the surfaces of the first titanium foil guide rail 3 and the second titanium foil guide rail 4 are polished to reduce the friction between them and the titanium foil 2, allowing the titanium foil 2 to move more smoothly within the first titanium foil guide rail 3 and the second titanium foil guide rail 4.

[0030] Titanium foil rolls 1 are installed at both ends of the first titanium foil guide rail 3 and the second titanium foil guide rail 4 along their length direction for alternately winding titanium foil 2. The titanium foil 2 is placed in the gap between the first titanium foil guide rail 3 and the second titanium foil guide rail 4, and its length is designed to be twice the length of the first titanium foil guide rail 3 and the second titanium foil guide rail 4. This design is the key to realizing the alternating cleaning of titanium foil 2, so that titanium foil 2 can be used alternately by moving left and right. After titanium foil 2 on one side has been used for a period of time, it can be moved to the other side to switch the unused part, ensuring that there is always a clean titanium foil area available for use during the cleaning process.

[0031] The cleaning mechanism consists of cleaning scrapers 5, with each end of the titanium foil roll 1 equipped with a cleaning scraper 5. Each set of scrapers corresponds to a different surface of the titanium foil 2 for cleaning the titanium foil 2. Preferably, the cutting edge of the cleaning scraper 5 forms an angle of 30° to 60° with the surface of the titanium foil 2. This angle setting effectively removes impurities from the surface of the titanium foil 2 while avoiding damage to the titanium foil 2. Preferably, the cleaning scraper 5 is made of stainless steel. Stainless steel not only has good wear resistance, maintaining stable scraping performance during long-term cleaning, but also has strong corrosion resistance, effectively resisting the erosion of the scraper by radiation, humidity, and corrosive environments, ensuring the continuous and stable operation of the cleaning work. Preferably, the cutting edge material of the cleaning scraper 5 is made of polytetrafluoroethylene (PTFE) or wear-resistant ceramic. PTFE has good chemical stability and a low coefficient of friction, will not chemically react with the titanium foil, and can reduce wear on the surface of the titanium foil. Wear-resistant ceramic has high hardness and wear resistance, maintaining a sharp cutting edge for a long time, ensuring the cleaning effect. As an feasible approach, the cleaning scraper 5 can also be made of materials such as resin.

[0032] The drive mechanism includes a first pneumatic motor 6 and a second pneumatic motor 7, which are respectively driven and connected to two titanium foil rolls 1, serving as the power source for rotating the titanium foil rolls 1. The first and second pneumatic motors 6 and 7 have advantages such as fast response speed and stable operation. To cope with the radiation environment, radiation shields are installed outside the first and second pneumatic motors 6 and 7, preferably lead glass shields. The lead glass shields can effectively block radiation, protect the precision components inside the pneumatic motors, extend their service life, and ensure stable operation of the entire cleaning device in a radiation environment. Driven by the first and second pneumatic motors 6 and 7, the titanium foil rolls 1 can drive the titanium foil 2 to move on the first titanium foil guide rail 3 and the second titanium foil guide rail 4, thereby realizing the unwinding and rewinding of the titanium foil rolls 1 and the change of the cleaning position. As an alternative implementation, an electric motor or similar device can also be used as the drive mechanism of this application.

[0033] The automatic control system is the core control component of the entire device, electrically connected to the first pneumatic motor 6 and the second pneumatic motor 7, and is used to control the entire cleaning process. Through pre-set programs, the automatic control system can precisely control the alternating left and right operation of the first pneumatic motor 6 and the second pneumatic motor 7, enabling flexible setting of the cleaning time and frequency of the titanium foil 2. This not only ensures the cleaning effect of the titanium foil 2 but also allows adjustments based on the actual operation of the electron accelerator, ensuring that the cleaning work is coordinated with the accelerator's operation and achieving uninterrupted cleaning. Preferably, in some scenarios, the automatic control system includes a time controller, a position sensor, and a reversing solenoid valve. The time controller is used to set the cleaning cycle and the duration of a single cleaning cycle; users can flexibly adjust the cleaning parameters according to actual usage to achieve automated cleaning. The position sensor is used to detect the extreme positions of the titanium foil 2's movement. When the titanium foil 2 moves to the ends of the first titanium foil guide rail 3 and the second titanium foil guide rail 4, the position sensor sends a signal. The reversing solenoid valve switches the air supply direction of the pneumatic motors according to the position sensor signal, thereby changing the rotation direction of the titanium foil roll 1, enabling the titanium foil 2 to move back and forth. Preferably, in some scenarios, an automatic control system may not be required; only an automatic cleaning device start switch is needed. The device is manually controlled to start and stop, thus achieving the cleaning purpose. This saves costs related to sensors, controllers, programming software, and related wiring. Workers only need to be familiar with the location and operation of the start switch, without needing to master complex automation programs, reducing personnel training costs and simplifying operation. This application achieves automatic cleaning of titanium foil 2 through an automatic control system, and can operate without shutting down the electron accelerator. Compared with traditional manual cleaning methods, this significantly reduces cleaning time and improves equipment operating efficiency.

[0034] How this application works:

[0035] During the operation of the electron accelerator, the automatic control system initiates the cleaning program according to a preset cleaning cycle. When the cleaning time is reached, the time controller sends a signal to start the pneumatic motor on one side. For example, the first pneumatic motor 6 on the right is started first. The first pneumatic motor 6 drives the titanium foil roll 1 on the right to rotate through the transmission chain, thereby pulling the titanium foil 2 to the right. During the movement of the titanium foil 2, the cleaning scraper 5 on the left scrapes the surface of the titanium foil 2 to remove water droplets, dust and other impurities attached to the surface. When the titanium foil 2 moves to the extreme position at the right end of the first titanium foil guide rail 3 and the second titanium foil guide rail 4, the position sensor detects the signal and sends it to the reversing solenoid valve. The reversing solenoid valve switches the air supply direction, stops the operation of the first pneumatic motor 6 on the right, and starts the second pneumatic motor 7 on the left. The second pneumatic motor 7 on the left drives the titanium foil roll 1 on the left to rotate, causing the titanium foil 2 to move to the left. At this time, the cleaning scraper 5 on the right cleans the titanium foil 2. By alternating the starting of the left and right pneumatic motors, the titanium foil 2 moves back and forth on the first titanium foil guide rail 3 and the second titanium foil guide rail 4, and is continuously cleaned by the cleaning scraper 5. Each movement allows the unused area of ​​the titanium foil 2 to enter the working position, ensuring that there is always clean titanium foil available for use in the scanning window under the electron accelerator beam. Thus, automatic cleaning of the titanium foil 2 is achieved without affecting the normal operation of the equipment.

[0036] Preferably, radiation shielding curtains are provided on both sides of the first titanium foil guide rail 3 and the second titanium foil guide rail 4. The shielding curtains are made of lead-containing rubber. Lead-containing rubber has good radiation protection performance, which can effectively block radiation leakage and reduce radiation hazards to the surrounding environment and personnel. At the same time, the shielding curtains can also play a certain role in dust prevention, preventing dust from entering the guide rails and titanium foil area, thus affecting the cleaning effect and normal operation of the equipment.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
