Description

Technical Field

[0001] This utility model relates to the field of water filtration technology, and in particular to a backwashable coal mine raw water iron and manganese removal filtration device. Background Technology

[0002] Coal mine raw water refers to water collected from the coal mining area and surrounding environment that has not undergone artificial purification treatment. Coal mine raw water usually contains silt, pathogens, dissolved ions and organic pollutants, and must be treated before it can be used for coal mine production and domestic water use. Among them, the filtration device is a water treatment equipment specifically used to remove iron and manganese ions from coal mine raw water.

[0003] A search revealed that Chinese patent CN222476383U discloses a filtration device for removing iron and manganese. In existing treatment devices, oxidation and precipitation filtration steps are usually performed simultaneously without separate aeration oxidation and precipitation filtration steps, resulting in uneven and insufficient reactions and poor actual purification effects. Therefore, a blocking baffle is used to isolate the reaction section from the filtration section, allowing the iron and manganese-containing water to be fully oxidized and precipitated in the reaction section. Afterwards, the blocking baffle is opened, connecting the reaction section and the filtration section for filtration. This separate operation of oxidation precipitation and filtration improves the treatment effect.

[0004] While the aforementioned filtration devices facilitate filtration, the impurities filtered out remain on the filter plates after water filtration, making them difficult to clean. This can lead to a buildup of impurities on the filter plates, resulting in slower water flow and blockages. Although some traditional filtration devices have a backwashing function, the filter plates inside are usually flat, which can create dead zones during backwashing. This reduces the quality of backwashing and makes it difficult to remove impurities, which tend to adhere to the filter plates, resulting in poor cleaning. Utility Model Content

[0021] As attached Figure 3 As shown, the fixed tube 16 is fixedly connected to one side of the filter frame 1, and the internal filler of the arc-shaped filter plate 8 is manganese sand and quartz sand, which facilitates filtration.

[0022] As attached Figure 1 As shown, an external gear ring 12 is fixedly connected to the outside of the first turntable 9, and a variable speed motor 13 is fixedly installed on the bottom side of the filter frame 1. A drive gear 14 is fixedly connected to the output end of the variable speed motor 13. The drive gear 14 and the external gear ring 12 are meshed, which facilitates the rotation of the external gear ring 12, thereby facilitating the rotation of the clamp flushing pipe 10.

[0023] As attached Figure 4 As shown, a second turntable 17 is rotatably connected to the other side of the filter frame 1, and a scraper 18 is fixedly connected to one side of the second turntable 17 to scrape the impurities flushed out of the surface of the arc-shaped filter plate 8.

[0024] As attached Figure 2As shown, a gear disk 19 is fixedly connected to the middle of the second turntable 17. The gear disk 19 is a disc-mounted gear. A fixed frame 20 and an electric cylinder 21 are fixedly connected to the other side of the filter frame 1. The electric cylinder 21 is located above the fixed frame 20. A sliding frame 22 is fixedly connected to the output end of the electric cylinder 21. The sliding frame 22 is slidably connected to the outside of the fixed frame 20.

[0025] As attached Figure 5 As shown, a disassembly assembly is provided on one side of the filter frame 1. The disassembly assembly includes an arc-shaped groove 24, which facilitates the installation of the arc-shaped filter plate 8. The arc-shaped groove 24 is located on one side of the filter frame 1.

[0026] As attached Figure 1 As shown, an installation bracket 25 is fixedly connected to one side of the arc-shaped filter plate 8 to facilitate the installation and positioning of the arc-shaped filter plate 8.

A pressure frame 27 is fixedly connected to the output end of the electric cylinder 26 to press down on the installation bracket 25, thereby facilitating the positioning of the installation bracket 25.

[0027] Working principle: In use, after the raw coal mine water is filtered by the arc-shaped filter plate 8, the water is discharged through the discharge pipe 3. When cleaning the arc-shaped filter plate 8 is required, the fixed pipe 16 is first connected to the external high-pressure water pipe. Water is then supplied to the fixed pipe 16 through the external high-pressure water pipe. The water flows through the fixed pipe 16 to the inside of the bidirectional pipe 15, and then reaches the inside of the flushing pipe 10 and is sprayed out through the flushing head 11. At this time, the external controller controls the drive speed motor 13, so that its output end drives the drive gear 14 to rotate. Under the meshing of the external gear ring 12, the external gear ring 12 drives the external gear ring 12 to rotate. When the external gear ring 12 drives the first turntable 9 to rotate, it will drive the bidirectional pipe 15 to rotate at one end of the fixed pipe 16, thereby driving the two flushing pipes 10 to rotate. When the flushing head 11 of the flushing pipe 10 passes the bottom of the arc-shaped filter plate 8... The process involves rinsing the arc-shaped filter plate 8 to flush out internal impurities to the surface. Then, the electric cylinder 21 is activated, causing its output end to slide the sliding frame 22 outside the fixed frame 20, thereby causing the rack 23 to move laterally. Under the action of the rack 23 meshing with the gear disk 19, the gear disk 19 is easily rotated. The gear disk 19 then drives the scraper 18 to scrape the upper surface of the arc-shaped filter plate 8, scraping the surface impurities to the openings of the drain pipes 5 on both sides. The opening and closing cover 6 is then opened to discharge the impurities. When it is necessary to disassemble the arc-shaped filter plate 8, the electric cylinder 26 is activated, causing its output end to move the pressure frame 27 upward. After the pressure frame 27 moves upward, it will release the limit on the mounting frame 25. Then, the mounting frame 25 is pulled laterally, causing the arc-shaped filter plate 8 to be pulled out from the inside of the arc-shaped groove 24, which facilitates the maintenance, cleaning and replacement of the arc-shaped filter plate 8.

[0028] This solution also includes an electrical control cabinet, which is installed on the equipment. During use, each piece of electrical equipment can be started and operated separately through the electrical control cabinet. The power connection method of each piece of electrical equipment is an existing mature technology and is well known to those in the field, so it will not be described in detail here.
