Description

Technical Field

[0001] This utility model relates to the field of quartz sand filters, and in particular to a quartz sand filter that is easy to clean. Background Technology

[0002] A quartz sand filter, also known as a shallow media filter, uses quartz sand as the filter medium. Under certain pressure, water with high turbidity is filtered through a certain thickness of granular or non-granular quartz sand. This effectively traps and removes suspended solids, organic matter, colloidal particles, microorganisms, chlorine, odors, and some heavy metal ions from the water, ultimately achieving the effect of reducing water turbidity and purifying water quality.

[0003] Quartz sand filters are generally used as pretreatment for reverse osmosis and ultrafiltration equipment. They are mainly used to intercept and adsorb silt, colloids, metal ions, and organic matter. Commonly used filter media include quartz sand, activated carbon, anthracite, and manganese sand. They are widely used in various industries such as agricultural irrigation, chemical, petroleum, metallurgy, and mining. After long-term use, quartz sand filters require cleaning and replacement of the internal packing. However, the existing quartz sand filter packing is directly arranged in the filter tank, which makes it inconvenient to replace the internal packing and leads to cleaning difficulties. Therefore, we propose a quartz sand filter that is easy to clean to solve the above problems. Utility Model Content

[0022] Please see Figure 1-4In this utility model, an easy-to-clean quartz sand filter includes a tank 1, a top cover 2 on the top of the tank 1, an inlet pipe 3 fixedly connected to the outer surface of the tank 1, a drain pipe 4 fixedly connected to the bottom of the tank 1, a fixing plate 13 fixedly connected inside the tank 1, a threaded opening 18 in the middle of the fixing plate 13, a connecting cylinder 16 threadedly connected inside the threaded opening 18, a limit ring 15 fixedly connected to the top of the connecting cylinder 16, and a filter sand cylinder 14 fixedly connected to the bottom of the connecting cylinder 16. The filter sand cylinder 14 is filled with quartz sand. By rotating the top cover 2 with the lifting lug 8, the top cover 2 is separated from the tank 1. Then, by rotating the limit ring 15 with the fixing rod 19, the limit ring 15 drives the connecting cylinder 16 to rotate, thereby separating the connecting cylinder 16 from the fixing plate 13, and removing all the quartz sand from the filter sand cylinder 14, thus facilitating the replacement of the whole filter.

[0023] Two lifting lugs 8 are fixedly connected to the outer surface of the top cover 2. The outer surface of the top cover 2 is threadedly connected to the inner wall of the tank 1. The lifting lugs 8 facilitate the hoisting of the filter and also facilitate the rotation of the top cover 2 during cleaning to separate the top cover 2 from the tank 1. An exhaust valve 7 is fixedly connected to the top of the top cover 2, and a pressure gauge 6 is fixedly connected to the outer surface of the top cover 2. The exhaust valve 7 facilitates the venting of the tank 1, and the pressure gauge 6 can detect the internal pressure of the filter.

[0024] The outer surface of the tank body 1 is fixedly connected to an inspection port 10. A sealing cover 9 is installed on the outer surface of the inspection port 10 by screws. The outer surface of the tank body 1 is provided with a display window 11. The inspection port 10 facilitates maintenance of the tank body 1. The sealing cover 9 facilitates sealing of the inspection port 10. Two sets of support legs 12 are fixedly connected to the outer surface of the tank body 1. Each support leg 12 is fixedly connected to a fixing ear 5. The support legs 12 support the filter. The fixing ear 5 facilitates fixation with the support legs 12. The upper surface of the fixing plate 13 is provided with a sealing ring 17. The upper surface of the limiting ring 15 is fixedly connected to two fixing rods 19. The sealing ring 17 ensures a tight seal between the limiting ring 15 and the fixing plate 13. The fixing rods 19 facilitate rotation with the limiting ring 15 to separate the connecting cylinder 16 from the fixing plate 13.

[0025] The working principle of this utility model is as follows:

[0026] In use, the quartz sand filter is first supported in its operating position by the support leg 12. The filter can be fixed by the fixing lug 5. Wastewater is sent into the tank 1 through the inlet pipe 3. The wastewater is filtered by the filter sand cylinder 14 in the tank 1. The filtered wastewater is discharged through the drain pipe 4 at the bottom of the tank 1. When replacing the quartz sand in the filter, the top cover 2 is rotated by the lifting lug 8 to separate the top cover 2 from the tank 1. Then, the limiting ring 15 is rotated by the fixing rod 19 to make the limiting ring 15 drive the connecting cylinder 16 to rotate, thereby separating the connecting cylinder 16 from the fixing plate 13. All the quartz sand in the filter sand cylinder 14 can be taken out, which makes it convenient to replace the whole filter.
