Description

Technical Field

[0001] This utility model relates to an environmentally friendly nuclear wastewater pretreatment filtration device, belonging to the field of nuclear wastewater treatment technology. Background Technology

[0002] Nuclear wastewater refers to wastewater containing radioactive materials generated from nuclear power plants and nuclear-related medical institutions or laboratories. Its main sources include wastewater generated during the normal operation of nuclear power plants, such as nuclear reactor cooling water. This wastewater does not directly contact the nuclear fuel and nuclear reactants in the reactor core. The mining and refining of uranium ore, as well as the application of radioactive elements in the pharmaceutical, industrial, and agricultural industries, also generate nuclear wastewater. The harm of nuclear wastewater comes from the radioactive elements it contains, which release alpha, beta, and gamma rays through their decay. These rays can penetrate the cells of organisms and may ionize chromosomes, thereby disrupting the normal function of cells and even the entire organism. For example, alpha rays often cause respiratory diseases, while beta rays can cause radiation hazards outside the body, with particularly noticeable damage to the eyes. Gamma ray irradiation can lead to diseases of the nervous and blood systems. These types of radiation hazards all belong to ionizing radiation damage and require treatment of nuclear wastewater to prevent direct discharge that could harm the environment and human health. Pre-treatment filtration of nuclear wastewater is necessary, which requires an environmentally friendly nuclear wastewater pre-treatment filtration device. However, existing nuclear wastewater pre-treatment filtration devices are not convenient for collecting impurities produced during filtration and are not convenient for cleaning the filter screen, causing the filter screen to become clogged and affecting the filtration effect.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-6 As shown, an environmentally friendly nuclear wastewater pretreatment filtration device includes a treatment tank 1. A box-type blower 2 is installed on the upper surface of the treatment tank 1. A winding machine 3 is installed on one side of the treatment tank 1, and a mounting cover 4 is installed on the other side of the treatment tank 1. A filter screen 5 is connected to the output end of the winding machine 3. The winding machine 3 facilitates the winding and unwinding of the filter screen 5. The filter screen 5 is slidably engaged with the treatment tank 1 and the mounting cover 4. A cleaning component 6 is installed inside the treatment tank 1. The cleaning component 6 can clean the filter screen 5, preventing the filter screen 5 from accumulating too many impurities over a long period of use, which would affect the filtration effect. The cleaning component 6 is fixedly connected to the output end of the box-type blower 2. The box-type blower 2 transmits air to the cleaning component 6, which facilitates the blowing off of impurities inside the filter screen 5, thereby making it easier to clean the filter screen 5.

[0022] like Figure 5As shown, the cleaning component 6 includes a fixing plate 601, which is fixedly installed inside the mounting cover 4. An array of cleaning brushes 602 are connected to the fixing plate 601. The cleaning brushes 602 clean the filter screen 5 as it moves out of or into the processing tank 1. The cleaning brushes 602 contact the filter screen 5. A horizontal pipe 603 is provided on one side of the fixing plate 601. An array of blower heads 604 are connected to the horizontal pipe 603. An air inlet pipe 605 is connected to the horizontal pipe 603 and is connected to the output end of the box-type blower 2. The box-type blower 2 transmits air to the air inlet pipe 605 and the horizontal pipe 603, and blows air onto the filter screen 5 through the blower heads 604. This blows off some impurities stuck on the filter screen 5, which are then collected by the collection box 9, improving the cleaning effect of the filter screen 5 and preventing any impact on the filtration effect.

[0023] like Figure 4 As shown, the inner wall of the processing tank 1 is provided with a first sliding groove 7. The filter screen 5 is slidably connected to the processing tank 1 through the first sliding groove 7. The inner wall of the processing tank 1 and the mounting cover 4, and located below the first sliding groove 7, are provided with a second sliding groove 8. A collection box 9 is slidably engaged on the second sliding groove 8 to facilitate the removal of impurities inside the collection box 9. The filter screen 5 is provided with a square hole 10. Through the square hole 10 and the inner wall of the processing tank 1, large pieces of impurities can fall into the collection box 9. One end of the filter screen 5 is provided with a baffle 11. The winding machine 3 can wind up the filter screen 5 and engage the baffle 11 with the processing tank 1 to tighten the filter screen 5. To prevent the filter screen 5 from being too loose and affecting filtration, the treatment tank 1 and the mounting cover 4 are provided with insertion holes 12. The filter screen 5 is inserted into the treatment tank 1 and the mounting cover 4 through the insertion holes 12. The mounting cover 4 and the collection box 9 are provided with snap-fit ​​grooves 13. The baffle 11 matches the snap-fit ​​grooves 13. The baffle 11 and the collection box 9 are provided with handles 14. The treatment tank 1 is provided with a feed inlet 15, through which raw materials can be added into the treatment tank 1. The treatment tank 1 is provided with a drain pipe 16 on one side, through which the filtered nuclear wastewater can be discharged from the treatment tank 1, thereby facilitating the further treatment of the nuclear wastewater.

[0024] In use, this utility model allows the addition of pre-treated nuclear wastewater to the processing tank 1 through the feed inlet 15. The wastewater is filtered through the filter screen 5, and the drain pipe 16 discharges the filtered wastewater from the processing tank 1, facilitating further processing. The winding machine 3 is started, and the handle 14 is pulled to remove the filter screen 5 from the processing tank 1. The filter screen 5 is cleaned using the cleaning brush 602. Simultaneously, the box-type blower 2 is started, transmitting air to the air inlet pipe 605 and the horizontal pipe 603. The blower head 604 blows air onto the filter screen 5, blowing off some impurities stuck on the filter screen 5 and collecting them through the collection box 9, improving the cleaning effect of the filter screen 5 and avoiding affecting the filtration effect. The inner wall of the treatment barrel 1 can block some larger impurities, and the impurities can fall into the collection box 9 through the square holes 10 for collection. After cleaning, the winding machine 3 is started, which can engage the baffle 11 with the treatment barrel 1, thereby tightening the filter screen 5 and preventing the filter screen 5 from being too loose, which would affect the filtration effect.
