Description

Technical Field

[0001] This utility model relates to the technical field of electron accelerator auxiliary equipment, specifically to an automatic water washing device under an electron accelerator beam. Background Technology

[0002] With increasing environmental protection demands and technological advancements, electron accelerators are finding wider applications in wastewater treatment. By emitting electron beams, electron accelerators utilize the high-energy electrons and active particles generated from water radiolysis to conduct physicochemical reactions with pollutants in wastewater, effectively degrading organic pollutants and killing microorganisms. This demonstrates advantages such as high efficiency, speed, and no secondary pollution, making it a research hotspot and development direction in the field of wastewater treatment.

[0003] In the process of treating wastewater in an electron accelerator, the titanium foil under the beam plays a crucial role in protecting the under-beam device. As an important component for electron beam transmission, the titanium foil is in close contact with wastewater for extended periods, making it highly susceptible to contamination by wastewater droplets, dust, salt, and other pollutants. Furthermore, the complex and harsh environment it operates in, with multiple factors including radiation, high temperature, high humidity, and ozone corrosion, makes the titanium foil extremely vulnerable to contamination and corrosion. Contamination and corrosion of the titanium foil surface severely reduce the accelerator's energy conversion efficiency, increase energy loss as the electron beam passes through the foil, and thus weaken the wastewater treatment effect. Moreover, frequent contamination and corrosion significantly shorten the lifespan of the titanium foil, necessitating frequent shutdowns for manual cleaning and maintenance. Manual cleaning is not only cumbersome and inefficient but also disrupts the continuity of the accelerator's wastewater treatment process, reducing throughput and increasing operating costs. More importantly, during manual cleaning, operators inevitably come into contact with harmful pollutants in the wastewater, posing a potential threat to their health.

[0004] Currently, various technologies and devices exist for material cleaning, but very few are suitable for cleaning titanium foil under electron accelerator beams. Take the conveyor belt rinsing device (CN202420225225.6) as an example; it is mainly used for belt cleaning and includes scraping, rinsing, squeegeeing, and wiping devices. However, leather conveyor belts and titanium foil have vastly different properties. Conveyor belts have good wear resistance, and the surface smoothness after cleaning has little impact on their use; while titanium foil requires extremely high surface smoothness. A rough surface can cause surface arcing, significantly increasing energy consumption when the electron beam passes through, and thus cannot meet the cleaning requirements of titanium foil under radiation conditions.

[0005] While the automatic cleaning device for radioactive source components (CN202220755451.6) meets the cleaning precision requirements for titanium foil, it requires the components being cleaned to be out of operation, which contradicts the need for continuous operation of electron accelerators. Furthermore, the ultrasonic cleaning method used in this device is ineffective in the extreme environment under the beam and cannot effectively cope with complex conditions such as radiation, high temperature, high humidity, and ozone corrosion.

[0006] Other automated cleaning devices also have many shortcomings. Most of these devices do not have high requirements for the residual moisture of the object being cleaned, and cannot meet the standard of low residual moisture after cleaning titanium foil. Furthermore, these devices and materials are highly susceptible to damage in the special environment of electron accelerator beams, making stable operation impossible.

[0007] Most existing automatic cleaning devices do not fully consider the special conditions of high temperature, humidity, radiation, and ozone corrosion under electron accelerator beams, making them difficult to apply to the critical field of electron beam irradiation. Existing manual cleaning methods and some automatic cleaning devices (such as scraper-type automatic cleaning devices) are prone to missed areas due to insufficient contact between the cleaning tool and the titanium foil surface, resulting in water stains and dirt residue on the titanium foil surface, further shortening the titanium foil's lifespan and increasing the amount of additional manual cleaning work.

[0008] Against this backdrop, it is urgent to develop a cleaning device that can adapt to the special environment under electron accelerator beams, achieve automatic cleaning without stopping the machine, effectively extend the service life of titanium foil, and ensure the stable operation of the accelerator. This is of great significance for promoting the widespread application of electron accelerators in the field of wastewater treatment. Utility Model Content

[0009] In view of this, the purpose of this utility model is to provide an automatic water washing device under an electron accelerator beam.

[0010] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0011] An automatic water washing device under an electron accelerator beam includes:

[0012] A support module includes a support frame and a titanium foil guide rail mounted on the support frame. A first power element is connected to the titanium foil guide rail, and the titanium foil guide rail can be tilted at an adjustable angle via the first power element. Titanium foil rolls are mounted at both ends of the titanium foil guide rail along its length. Titanium foil extending from the titanium foil rolls is disposed on the titanium foil guide rail, and a second power element is connected to each titanium foil roll. The second power element drives the titanium foil roll to move the titanium foil on the titanium foil guide rail.

[0013] The cleaning module includes a pressure water gun, a water absorption roller, and a drying system. The pressure water gun, the water absorption roller, and the drying system are respectively paired and installed at both ends of the support frame, and all of them act on the titanium foil. The water absorption roller is disposed between the pressure water gun and the drying system.

[0014] The automatic control system is electrically connected to the first power element, the second power element, the pressure water gun, the water absorption roller, and the drying system, and configures the start-up, shutdown, and operation parameters of the first power element, the second power element, the pressure water gun, the water absorption roller, and the drying system.

[0015] A radiation shielding module is mounted on the support frame, and the radiation shielding module covers the first power element, the second power element, the pressure water gun, the water absorption roller and the drying system.

[0016] Furthermore, both the support frame and the titanium foil guide rail are two-layer structures with a gap in the middle, and the titanium foil is disposed in the gap.

[0017] Furthermore, the first power element is a stepper motor, and the stepper motor drives the titanium foil guide rail to tilt at an angle of 0° to 180°.

[0018] Furthermore, the length of the titanium foil is twice the length of the titanium foil guide rail.

[0019] Furthermore, the second power element is a pneumatic motor.

[0020] Furthermore, the radiation module includes a protective box structure, which is made of lead plate or lead glass.

[0021] Furthermore, the filler of the absorbent roller is ultrafine silica or other inorganic radiation-resistant absorbent materials.

[0022] Furthermore, the drying system includes a high-pressure air pump and an air knife.

[0023] Furthermore, the pressure water gun is configured to spray tap water, recycled water, or cleaning fluid.

[0024] Furthermore, the support frame and the titanium foil guide rail are made of stainless steel, resin, or other corrosion-resistant and radiation-resistant materials.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0026] 1. This system solves the problem of cleaning titanium foil during accelerator operation. With the aid of a dedicated automatic control system, titanium foil can be cleaned without shutting down the accelerator, avoiding frequent downtime caused by manual cleaning, effectively reducing hazards to operators, significantly increasing continuous operating time, and minimizing downtime. By setting cleaning time, frequency, clean water flow rate, titanium foil tilt angle, and drying device wind speed, the system ensures thorough and appropriate cleaning of the titanium foil, guaranteeing the irradiation effect of the electron accelerator, reducing the frequency of titanium foil replacement and manual operation, and thus saving costs. Simultaneously, effective cleaning of the titanium foil reduces corrosion caused by the special environment, significantly extending the service life of the titanium foil under the beam.

[0027] 2. By using lead boxes to protect the water suction roller, drying system, pressure water gun, pneumatic motor, and stepper motor, and by using stainless steel and other corrosion-resistant materials for the titanium foil guide rail, the radiation protection capability is improved, and the corrosion resistance is also enhanced, thus improving the service life of the equipment in harsh environments.

[0028] 3. By filling the absorbent roller with ultrafine silica as an inorganic filler, the corrosion of organic materials such as sponge by high temperature, ozone and radiation is effectively avoided, which not only ensures the water absorption effect, but also extends the service life of the absorbent roller.

[0033] 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.

[0034] Most existing automated cleaning devices do not consider applications in high-temperature, humid, radiation-exposed, or ozone-corrosion environments, making them unsuitable for use in the specific environment of electron beam irradiation. Current manual cleaning methods require frequent accelerator switching, causing frequent process interruptions, reduced productivity, increased operator workload, and posing a threat to worker health. Scraper-type automated cleaning devices may miss areas due to incomplete contact between the titanium foil surface and the cleaning tool (e.g., scraper), resulting in water stains and dirt residue on the titanium foil surface, shortening its lifespan or requiring additional manual cleaning. See appendix. Figure 1 As shown, an automatic water washing device under an electron accelerator beam according to this application includes a support module, a cleaning module, an automatic control system, and a radiation protection module. The support module includes a support frame 100 and a titanium foil guide rail 101 mounted on the support frame 100. Both the support frame 100 and the titanium foil guide rail 101 are designed as two-layer structures with a gap in the middle. A first power element 103 is connected to the titanium foil guide rail 101. The first power element 103 is preferably a stepper motor, which can precisely control the tilt angle of the titanium foil guide rail 101, with a tilt angle range of 0° to 180°. Titanium foil rolls 107 are installed at both ends of the titanium foil guide rail 101 along its length. Titanium foil 102 extends from the titanium foil rolls 107 and is placed on the titanium foil guide rail 101, that is, the titanium foil 102 is placed in the middle gap of the titanium foil guide rail 101. This gap structure design is beneficial to the installation and movement of the titanium foil 102, and can effectively avoid interference from other components on the movement of the titanium foil 102. Meanwhile, each titanium foil roll 107 is connected to a second power element 108, preferably a pneumatic motor. The pneumatic motor drives the titanium foil roll 107 to rotate, thereby causing the titanium foil 102 to move on the titanium foil guide rail 101. The length of the titanium foil 102 in this application is designed to be twice the length of the titanium foil guide rail 101. In this way, during the cleaning process, by controlling the forward and reverse rotation of the pneumatic motor, different parts of the titanium foil 102 can be cleaned alternately, ensuring that all parts of the titanium foil 102 are effectively cleaned.

[0035] The cleaning module is responsible for cleaning and drying the titanium foil 102, and includes a pressure water gun 104, a water-absorbing roller 105, and a drying system 106. The pressure water gun 104, water-absorbing roller 105, and drying system 106 are installed in pairs at both ends of the support frame 100, and all act on the titanium foil 102. The pressure water gun 104, water-absorbing roller 105, and drying system 106 are arranged in sequence, with the water-absorbing roller 105 positioned between the pressure water gun 104 and the drying system 106. The pressure water gun 104 is configured to spray tap water, recycled water, or cleaning fluid. During the cleaning process, the pressure water gun 104 sprays the cleaning fluid onto the surface of the titanium foil 102 at a certain pressure, washing away contaminants on the titanium foil 102 to achieve cleaning. The variety of cleaning fluids can be adjusted according to the degree of contamination of the titanium foil 102 and actual needs, improving the flexibility and effectiveness of the cleaning process. The filler of the water-absorbing roller 105 is ultrafine silica or other inorganic radiation-resistant water-absorbing materials. After cleaning, residual moisture remains on the surface of the titanium foil 102. The absorbent roller 105 absorbs this moisture through its internal filler, effectively reducing water stains on the surface of the titanium foil 102. Ultrafine silica or other inorganic radiation-resistant absorbent materials possess excellent water absorption performance and stability, and are not easily corroded in the special environment of an electron accelerator beam, ensuring the long-term stable operation of the absorbent roller 105. The drying system 106 includes a high-pressure air pump and an air knife. The high-pressure air pump generates a high-pressure airflow, which is then evenly blown onto the surface of the titanium foil through the air knife, further drying the residual moisture on the surface of the titanium foil 102. This ensures that the titanium foil 102 can quickly reach a dry state after cleaning, meeting the operational requirements of the electron accelerator.

[0036] The automatic control system is electrically connected to the pressure water gun 104, the suction roller 105, the drying system 106, the pneumatic motor, and the stepper motor. The automatic control system configures the start / stop and operating parameters of the pressure water gun 104, the suction roller 105, the drying system 106, the pneumatic motor, and the stepper motor through a preset program. Operators can set parameters such as cleaning time, cleaning frequency, cleaning water flow rate, the tilt angle of the titanium foil 102, and the airflow speed of the drying device through the automatic control system. Since the titanium foil roll 107 is fixed at both ends of the titanium foil guide rail 101 and connected to the titanium foil 102, and the titanium foil roll 107 is connected to a pneumatic motor, when the pneumatic motor starts, it drives the titanium foil roll 107 to pull the titanium foil 102. Simultaneously, the pressure water gun 104 and the drying system 106 also start working. The length of the titanium foil 102 is designed to be twice the length of the titanium foil guide rail 101. When the right pneumatic motor starts, the titanium foil 102 is wound around the right titanium foil roll 107, and the titanium foil 102 pulled out from the left is used for cleaning. For subsequent cleaning, the left pneumatic motor starts, and the titanium foil 102 moves to the left and is wound around the left titanium foil roll 107, using the titanium foil 102 pulled out from the right. This alternating left and right movement achieves automatic cleaning of the titanium foil 102 without affecting the cleaning operation during equipment operation. By controlling the coordinated operation of various components through an automated control system, titanium foil can be automatically cleaned without shutting down the electron accelerator. This avoids frequent downtime caused by manual cleaning, increases the continuous operating time of the equipment, ensures the continuity of the wastewater treatment process, and reduces economic losses caused by downtime. The automation of titanium foil cleaning reduces the frequency of manual operation, significantly lowers the operator's exposure time to wastewater, and protects the operator's health.

[0037] A radiation shielding module is mounted on the support frame 100 to protect critical components of the device from electron accelerator radiation. The module includes a protective box structure made of lead plate or lead glass, which encloses the pressure water gun 104, suction roller 105, drying system 106, pneumatic motor, and stepper motor. This effectively blocks radiation, reduces damage to these components, extends their lifespan, and ensures stable operation of the device in the special environment of the electron accelerator beam. Simultaneously, this reduces the potential harm of radiation to operators and improves operational safety. Preferably, the automatic control system of this application can be used, or other methods can be selected according to actual conditions. The automatic control system precisely controls the cleaning frequency of the titanium foil 102 by controlling the on / off times of the pressure water gun 104, suction roller 105, drying system 106, pneumatic motor, and stepper motor, thus replacing manual cleaning and achieving automatic cleaning of the titanium foil 102. Operators only need to set the relevant parameters in the automatic control system, and the system can automatically complete the cleaning process according to the preset program, greatly improving cleaning efficiency and accuracy. However, in certain special cases, such as during equipment commissioning or in scenarios where a high degree of automation is not required, an automatic control system may not be necessary. Instead, a switch that is manually controlled to start and stop the device can be installed to achieve semi-automatic cleaning. Although this method requires more human intervention, it offers a degree of flexibility and operability.

[0038] Preferably, due to the flexibility in setting the tilt angle of the titanium foil 102, a stepper motor can be omitted, and the tilt angle of the titanium foil 102 can be fixed. In some cases where cleaning requirements are relatively low and the operating environment is relatively stable, fixing the tilt angle of the titanium foil 102 can simplify the device structure and reduce costs. However, when it is necessary to adjust the tilt angle of the titanium foil according to different cleaning conditions, various methods can be used. Preferably, a hydraulic drive device or an electric actuator can be used, and the tilt angle of the titanium foil guide rail 101 can be adjusted by precisely controlling the extension or rotation of these devices, thereby meeting different cleaning needs.

[0039] Preferably, the filler for the absorbent roller 105 is not limited to ultrafine silica; other inorganic absorbent materials or organic radiation-resistant materials can also be used. For example, inorganic absorbent materials such as activated alumina and bentonite, as well as certain specially treated organic radiation-resistant polymers, all possess good absorbency and radiation resistance properties. The selection of different fillers for the absorbent roller 105 can be comprehensively considered based on factors such as the specific environment under the electron accelerator beam and cost, ensuring that the absorbent roller 105 can stably perform its absorbent function even in harsh environments, thus guaranteeing the cleaning effect of the titanium foil 102.

[0040] Preferably, a heating drying device can be used to rapidly evaporate the moisture from the titanium foil; alternatively, a vacuum drying device can be used to accelerate the vaporization of moisture under low pressure. Different drying devices are suitable for different scenarios and can be selected according to actual needs to ensure that the titanium foil 102, after cleaning, meets the operating requirements of the electron accelerator.

[0041] Preferably, the support frame 100 and the titanium foil guide rail 101 are made of stainless steel, resin, or other corrosion-resistant materials. These materials have good corrosion resistance and can maintain stable performance in environments such as humidity and ozone corrosion under electron accelerator beams, extending the service life of the support frame 100 and the titanium foil guide rail 101 and ensuring the structural stability of the entire device.

[0042] Preferably, the width of the entire device is greater than the length of the device under the accelerator beam, ensuring that the device can completely cover the area under the accelerator beam that needs to be cleaned during installation and operation. The width of the titanium foil 102 is precisely calculated based on the tilt angle and the width of the device under the beam, ensuring that the titanium foil 102 can effectively receive the rinsing water at different tilt angles without any cleaning dead zones.

[0043] The usage process of this application is as follows:

[0044] Once the electron accelerator starts operating, the automatic control system sets parameters such as cleaning time, cleaning frequency, and cleaning water flow rate based on the contamination level of the titanium foil 102. After the set cleaning time is reached, the automatic control system initiates the cleaning program. First, a pneumatic motor drives the titanium foil roll 107, moving the titanium foil 107 to a suitable position on the titanium foil guide rail 101. Simultaneously, a stepper motor adjusts the tilt angle of the titanium foil guide rail 101 to achieve the optimal cleaning angle for the titanium foil 102. The pressure water gun 104 then sprays cleaning fluid to rinse the surface of the titanium foil 102. Under the influence of gravity and pressure, the cleaning fluid washes away contaminants from the surface of the titanium foil 102 and flows by gravity into the waste liquid collection device. By adjusting the tilt angle of the titanium foil guide rail 101, the rinsing water can flow out of the titanium foil 102 quickly under gravity, improving cleaning efficiency and facilitating adjustment of the titanium foil 102's position according to actual cleaning needs. After cleaning, the absorbent roller 105 begins operation, absorbing residual moisture from the surface of the titanium foil 102. The filler inside the absorbent roller 105 effectively absorbs moisture, reducing water stains on the surface of the titanium foil 102. Finally, the drying system 106 is activated, and the high-pressure airflow generated by the high-pressure air pump is blown onto the surface of the titanium foil 102 through the air knife, further drying the moisture on the surface of the titanium foil 102 until it reaches a dry state. After cleaning one side of the titanium foil 102, the pneumatic motor reverses, moving the titanium foil 102 to the other side, repeating the above cleaning process to achieve a complete cleaning of the titanium foil 102.

[0045] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. 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.
