[0001] This utility model relates to the field of filtration equipment technology, specifically to a cooling water circulation filtration device for oxygen production. Background Technology

[0002] "Oxygen production cooling water circulation filtration equipment" is a complete water treatment system used in industrial oxygen production (especially cryogenic air separation oxygen production) to treat, cool, and recycle the cooling water supplied to key oxygen production equipment (such as air compressors, booster compressors, oxygen compressors, nitrogen compressors, oil coolers, etc.). Its core purpose is to ensure that the water quality and temperature of the cooling water meet the equipment requirements, thereby ensuring the safe, stable, efficient, and long-term operation of the oxygen production equipment, and saving water resources and energy.

[0003] A search revealed a Chinese patent publication number, CN219783999U, which provides a cooling water circulation filtration device for oxygen production. This patent describes a device where the circulating water is cooled once by an agitator in the cooling chamber, and then further cooled by heat dissipation fins on the top cover of the filter chamber. This ensures effective cooling of the circulating water while improving cooling efficiency. The multi-layered filter screens inserted into the filter chamber effectively purify the circulating water and are easily disassembled for later cleaning of scale on the filter screens.

[0004] Although the aforementioned patent can effectively address the issue of cooling water circulation filtration equipment for oxygen production, the aforementioned cooling water circulation filtration equipment for oxygen production still has the following problems: during the use of the device, because the water flow needs to be filtered, the impurities after filtration are easily deposited inside the filter chamber, making it inconvenient to clean the device, the filter screen is easily clogged by impurities, the maintenance cost is high, and the working efficiency is low.

[0005] In response to the above situation, technological innovation should be carried out based on the existing equipment. Utility Model Content

[0006] The purpose of this invention is to provide a cooling water circulation filtration device for oxygen production, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cooling water circulation filtration device for oxygen production, comprising a cooling chamber, a filtration chamber, and a water storage tank. The cooling chamber is connected to the filtration chamber via a pipe, and the filtration chamber is connected to the water storage tank via a pipe. A cover plate is fixedly connected to the top of the filtration chamber. Two fixed plates are fixedly connected inside the filtration chamber. Each of the two fixed plates has a movable groove inside. A transmission cleaning device is provided inside the movable groove. The transmission cleaning device includes a movable frame. The surface of the movable frame is slidably connected to the inside of the movable groove. The cross-section of the movable frame is U-shaped. A groove is provided at the bottom of the movable frame, and a scraper is rotatably connected inside the groove.

[0008] Preferably, the filter chamber has a collection groove inside, a forward and reverse motor is fixedly connected to one side of the filter chamber, and threaded rods extending to the outside of the filter chamber are rotatably connected inside the two moving grooves.

[0009] Preferably, the output end of the positive and negative motor rotates through one side of the filter chamber and extends into the interior of the moving groove. The output end of the positive and negative motor is fixedly connected to one end of the threaded rod, and a moving frame is slidably connected inside the moving groove.

[0010] Preferably, the surface of the threaded rod is connected to the internal thread of the movable frame, and protective sleeves fitted onto the threaded rod are fixedly connected to both sides of the movable frame. The end of the protective sleeve away from the movable frame is fixedly connected to the inner wall of the movable groove.

[0011] Preferably, both of the threaded rod surfaces are fixedly connected to sprockets, and the outer surfaces of the sprockets are engaged with chains.

[0012] Preferably, a positioning groove is provided on one side of the movable frame, and a positioning plate is slidably connected inside the positioning groove. The cross-section of the positioning plate and the positioning groove are both trapezoidal. A cleaning plate is fixedly connected to one side of the positioning plate, and a brush is fixedly connected to the side of the cleaning plate away from the positioning plate.

[0013] Preferably, torsion springs are fixedly connected to both sides of the scraping plate, and one end of the torsion spring far from the scraping plate is fixedly connected to the inner wall of the groove.

[0014] Preferably, a maintenance groove is provided on the top of the cover plate, and a maintenance plate is fixedly connected inside the maintenance groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. In this oxygen-generating cooling water circulating filtration equipment, when the scraper moves towards the direction of the forward and reverse motors, it can rotate due to the resistance of the water flow. When the scraper moves away from the direction of the forward and reverse motors, the grooves block the scraper, allowing it to scrape impurities more smoothly. The moving frame drives the scraper to move, enabling it to scrape and clean the impurities deposited on the inner wall of the filter chamber, allowing the impurities to enter the collection tank for collection, and making the cleaning of the device more convenient.

[0017] 2. This oxygen-generating cooling water circulation filtration equipment uses brushes on a cleaning plate to clean impurities attached to the filter screen, reducing the accumulation of impurities and thus minimizing the reduction in water flow filtration speed. This significantly reduces the difficulty of cleaning the filter screen for operators. The protective sleeve protects the threaded rod, extending its service life. Attached Figure Description

[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] Please see Figures 1-5As shown, a cooling water circulation filtration device for oxygen production includes a cooling chamber 1, a filter chamber 2, and a water storage tank 3. The cooling chamber 1 is connected to the filter chamber 2 via a pipe, and the filter chamber 2 is connected to the water storage tank 3 via a pipe. The cooling chamber 1, filter chamber 2, and water storage tank 3 are all existing structures and will not be described in detail here. The filter chamber 2 is equipped with a filter screen to filter the water that enters the filter chamber 2 after being cooled by the cooling chamber 1. A cover plate 4 is fixedly connected to the top of the filter chamber 2. Two fixed plates 8 are fixedly connected inside the filter chamber 2. Each of the two fixed plates 8 has a moving groove 9 inside, and a transmission cleaning device is installed inside the moving groove 9.

[0026] The transmission cleaning device includes a movable frame 10, the surface of which is slidably connected to the interior of the movable groove 9. The movable frame 10 has a U-shaped cross section and a groove 16 at its bottom. A scraper 17 is rotatably connected inside the groove 16. The scraper 17 can scrape and clean the sediment and impurities accumulated inside the filter chamber 2. A collection groove 21 is provided inside the filter chamber 2. The collection groove 21 concentrates the cleaned impurities after filtration. A drain pipe is provided on the filter chamber 2. The drain pipe can discharge the impurities inside the collection groove 21.

[0027] Furthermore, a forward and reverse motor 7 is fixedly connected to one side of the filter chamber 2. A power supply, wiring, controller, and microcomputer structure are provided to match the forward and reverse motor 7. Since the forward and reverse motor 7 is not a major structure, it will not be described in detail. Threaded rods 11 extending to the outside of the filter chamber 2 are rotatably connected inside both moving slots 9. The output end of the forward and reverse motor 7 rotatably passes through one side of the filter chamber 2 and extends into the interior of the moving slot 9. The output end of the forward and reverse motor 7 is fixedly connected to one end of the right-side threaded rod 11. The surface of the threaded rod 11 is threadedly connected to the inside of the moving frame 10. Protective sleeves 12, which are fitted onto the threaded rods 11, are fixedly connected to both sides of the moving frame 10. The end away from the movable frame 10 is fixedly connected to the inner wall of the movable groove 9. The protective sleeve 12 is a corrugated pipe. The protective sleeve 12 can protect the threaded rod 11 and extend its service life. The surfaces of the two threaded rods 11 are fixedly connected to sprockets 19. The outer surfaces of the sprockets 19 are meshed with chains 20. The two sprockets 19 rotate through the chains 20 and make the two threaded rods 11 rotate synchronously. This allows the two threaded rods 11 to drive the movable frame 10 to move more smoothly, and the movable frame 10 can more conveniently drive the scraper 17 to scrape and clean the impurities deposited on the lower surface of the filter chamber 2.

[0028] Furthermore, a positioning groove 15 is provided on one side of the movable frame 10, and a positioning plate 14 is slidably connected inside the positioning groove 15. Both the positioning plate 14 and the positioning groove 15 have trapezoidal cross sections. A cleaning plate 13 is fixedly connected to one side of the positioning plate 14, and a brush is fixedly connected to the side of the cleaning plate 13 away from the positioning plate 14. The cleaning plate 13 can clean the impurities attached to the filter screen through the brush, and to a certain extent reduce the accumulation of impurities on the filter screen, thereby reducing the filter screen's water flow filtration speed and greatly reducing the difficulty for operators to clean the filter screen.

[0029] Furthermore, torsion springs 18 are fixedly connected to both sides of the scraping plate 17, and one end of the torsion spring 18 far from the scraping plate 17 is fixedly connected to the inner wall of the groove 16.

[0030] Furthermore, a maintenance groove 6 is provided on the top of the cover plate 4, and a maintenance plate 5 is fixedly connected inside the maintenance groove 6. By disassembling the maintenance plate 5, the operator can easily clean the internal filter screen of the filter chamber 2, which greatly improves convenience.

[0031] The operator starts the forward and reverse motor 7, and the water to be filtered enters the cooling chamber 1 through the pipe. After being cooled in the cooling chamber 1, the water enters the filter chamber 2 and is filtered through the filter screen inside the filter chamber 2. The forward and reverse motor 7 drives the threaded rod 11 to move. Through the transmission of the sprocket 19 and the chain 20, the two threaded rods 11 can rotate synchronously, and the threaded rods 11 can drive the moving frame 10 to move back and forth. The moving frame 10 drives the cleaning plate 13 to move. The cleaning plate 13, with its brushes, can clean the impurities attached to the filter screen and, to a certain extent, reduce the accumulation of impurities on the filter screen, thus reducing the filtration speed of the water flow. This greatly reduces the difficulty of cleaning the filter screen for operators. The protective sleeve 12 can protect the threaded rod 11, thus extending its service life. At the same time, the moving frame 10 drives the scraper 17 to move, allowing the scraper 17 to scrape and clean the impurities deposited on the inner wall of the filter chamber 2, so that the impurities can be collected in the collection tank 21. When the scraper 17 moves towards the direction of the forward and reverse motor 7, it can rotate under the resistance of the water flow. When the scraper 17 moves away from the direction of the forward and reverse motor 7, the groove 16 blocks the scraper 17, allowing it to scrape the impurities more smoothly.

[0032] Working Principle: For this type of oxygen-generating cooling water circulation filtration equipment, the operator first starts the forward and reverse motor 7. The water to be filtered enters the cooling chamber 1 through a pipe. After being cooled in the cooling chamber 1, the water enters the filter chamber 2, where it is filtered through a filter screen. The forward and reverse motor 7 drives the threaded rods 11 to move. Through the transmission of the sprocket 19 and chain 20, the two threaded rods 11 rotate synchronously, causing the threaded rods 11 to drive the moving frame 10 to move reciprocally. The moving frame 10, in turn, moves the cleaning plate 13. The cleaning plate 13, with its brushes, cleans the impurities adhering to the filter screen. The cleaning process is carried out simultaneously, and the scraper 17 is moved by the moving frame 10, so that the scraper 17 can scrape and clean the impurities deposited on the inner wall of the filter chamber 2, and collect the impurities into the collection tank 21. At the same time, when the scraper 17 moves closer to the forward and reverse motor 7, it can rotate under the resistance of the water flow. When the scraper 17 moves away from the forward and reverse motor 7, the groove 16 blocks the scraper 17, which can scrape the impurities more smoothly, concentrate the impurities in the collection tank 21 and discharge them through the collection tank 21. The filtered water flows into the water storage pipe through the pipe.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
