Description

Technical Field

[0001] This utility model relates to the field of water filter technology, and in particular to a fully automatic water filter with flat inlet and flat outlet and automatic backwashing. Background Technology

[0002] Industrial and mining enterprises discharge large amounts of wastewater during production, which needs to be filtered before discharge. This wastewater often contains solid impurities. In existing technologies, the inlet and outlet pipes of industrial and mining enterprises are generally horizontal and straight. Filters need to be adapted to this design to change the direction of water flow. While existing filters can achieve a filtering effect, solid impurities easily adhere to the surface of the filter elements during use, leading to clogging. Current filters mostly rely on manual cleaning or frequent replacement of filter elements to maintain filtration effectiveness. However, this not only consumes significant time, labor, and financial resources but also interferes with the normal filtration of wastewater.

[0003] The Chinese patent website discloses a fully automatic water filter with a flat inlet and flat outlet and automatic backwashing, designated "CN219355519U". This filter uses a U-shaped backwash arm to backwash and regenerate the filter elements, creating a cycle that avoids frequent replacements or manual cleaning, thus improving production efficiency and saving significant time, labor, and financial resources. However, the backwashing process generates vibration, causing the filter to shake and reducing its lifespan. Utility Model Content

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 3 This utility model discloses a fully automatic water filter with flat inlet and flat outlet and automatic backwashing, comprising: a filter body 1, a cylinder 2 disposed on the outer surface of the filter body 1, a telescopic rod 3 fixedly connected to the output end of the cylinder 2, a motor 4 fixedly connected to the end of the telescopic rod 3 away from the cylinder 2, a waterproof layer 22 fixedly connected to the outer surface of the motor 4, a rotating disk 5 fixedly connected to the waterproof layer 22, a rotating disk 5 fixedly connected to the output end of the motor 4, a plurality of filter cylinders 6 disposed on the upper surface of the rotating disk 5, an opening 7 provided on the rotating disk 5, the filter cylinders 6 communicating with the opening 7, and a drain pipe 8 disposed on the inner surface of the filter body 1. A sealing ring 20 is provided on the surface. A drain valve 9 is provided on the upper surface of the drain pipe 8. An inlet pipe 10 and an outlet pipe 11 are provided on the outer surface of the water filter body 1. An inlet pressure gauge 23 is provided on the outer surface of the inlet pipe 10. An outlet pressure gauge 24 is provided on the outer surface of the outlet pipe 11. A fixed cylinder 16 is movably connected to the outer surface of the rotating disc 5. The fixed cylinder 16 is connected to the outlet pipe 11. A support circular plate 17 is fixedly connected to the outer surface of the fixed cylinder 16. The water filter body 1 is fixedly connected to the outer surface of the support circular plate 17. An observation window 18 is provided on the outer surface of the water filter body 1. A differential pressure display 19 is provided on the outer surface of the water filter body 1.

[0025] Specifically, water enters the filter body 1 through the inlet pipe 10, and then enters the filter cylinder 6 through the opening 7 on the rotating disc 5. After being filtered by the filter cylinder 6, the water is discharged from the outlet pipe 11. When there are too many impurities on the inner surface of the filter cylinder 6, the filtration resistance increases and the pressure difference increases. When the pressure difference reaches a certain level, the motor 4 starts, which drives the rotating disc 5 to rotate until one of the openings 7 is above the drain pipe 8 and then stops. At this time, the cylinder 2 starts, which drives the rotating disc 5 to move downward through the telescopic rod 3. The sealing ring 20 on the drain pipe 8 enters the opening 7 and opens the drain valve 9. Affected by the pressure difference, the water flow is pushed back into the filter cylinder 6 to backwash the filter cylinder 6. The impurities on the inner surface of the filter cylinder 6 are discharged from the drain pipe 8 with the water flow. The telescopic rod 3 drives the rotating disc 5 to rise, and the above process is repeated to backwash all the filter cylinders.

[0026] Reference Figure 1 , Figure 2 and Figure 4The outer surface of the water filter body 1 is fitted with a mounting platform 12. A spring 13 is provided on the inner surface of the mounting platform 12. A damper 14 is provided on the outer surface of the spring 13. A placement plate 15 is fixedly connected to the upper surface of the damper 14. A support leg 21 is fixedly connected to the lower surface of the mounting platform 12. An anti-slip pad is fixedly connected to the lower surface of the support leg 21.

[0027] Specifically, when the water filter body 1 vibrates during backwashing, the vibration is transmitted to the placement plate 15. Through the cooperation of the spring 13 and the damper 14, the vibration effect is reduced, and the shaking of the water filter body 1 is lessened.

[0028] Working principle: When using this device, water enters the filter body 1 from the inlet pipe 10, and enters the filter cylinder 6 through the opening 7 on the rotating disk 5. After being filtered by the filter cylinder 6, it is discharged from the outlet pipe 11. When there are too many impurities on the inner surface of the filter cylinder 6, the filtration resistance increases and the pressure difference increases. When the pressure difference reaches a certain level, the motor 4 starts and drives the rotating disk 5 to rotate. It stops when one of the openings 7 is above the drain pipe 8. At this time, the cylinder 2 starts and drives the rotating disk 5 to move downward through the telescopic rod 3. The sealing ring 20 on the drain pipe 8 enters the opening 7 and opens the drain valve 9. Affected by the pressure difference, the water flow is pushed back into the filter cylinder 6 to backwash the filter cylinder 6. The impurities on the inner surface of the filter cylinder 6 are discharged from the drain pipe 8 with the water flow. The telescopic rod 3 drives the rotating disk 5 to rise. The above process is repeated to backwash all the filter cylinders.

[0029] When the water filter body 1 is backwashed, it vibrates. The vibration is transmitted to the placement plate 15. Through the cooperation of the spring 13 and the damper 14, the vibration effect is reduced and the shaking of the water filter body 1 is lessened.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
