Description

Technical Field

[0001] This utility model relates to the field of water inlet filtration technology, specifically a water inlet filtration device for water treatment in a water plant. Background Technology

[0002] When water is being treated, water plants need to filter the incoming water first to remove larger impurities.

[0003] The water treatment inlet filtration device in the water plant has a drain pipe at the bottom, which discharges water directly. This results in low water pressure inside the tank, leading to poor filtration. A large amount of unfiltered water flows directly away from the drain pipe, affecting filtration efficiency. At the same time, the lack of automated cleaning of the filter components affects their service life.

[0004] As disclosed in CN222151092U, a water treatment inlet filtration device for a water plant is designed such that by placing the main drain pipe at the top of the main drain pipe, the incoming water flow must submerge the filter cartridge before being discharged from the main drain pipe. This fully utilizes the filtration efficiency of the filter cartridge. At the same time, when the water level is higher than that of the treatment tank, the water body must push the flow-limiting piston upward under the push of the thrust spring to open the drain branch pipe in order to discharge the water flow. This allows the treatment tank to have a certain water pressure, which can improve the filtration efficiency of the filter cartridge.

[0005] However, the device is not very effective at cleaning the filter cartridge during use, which affects the water filtration efficiency.

[0006] Therefore, we urgently need to provide a water inlet filtration device for water treatment plants. Utility Model Content

[0011] Preferably, the mounting plate is located at the upper end of the water inlet pipe, the drain pipe is located between the top plate and the mounting plate, and the filter cylinder is connected to the mounting plate. After water is introduced into the filter box through the water inlet pipe, as the water level rises, the water will enter the filter cylinder through the mounting plate and be filtered by the filter cylinder. The water then passes through the filter cylinder and is discharged and collected through the drain pipe, thus achieving water filtration.

[0012] Preferably, the large gear and the small gear mesh with each other, and the scraper is in contact with the inner wall of the filter cylinder. By starting the motor, the rotating shaft and the large gear are driven to rotate, and the large gear and the small gear mesh with each other, so that the connecting rod drives the scraper to rotate and clean the impurities on the inner wall of the filter cylinder, thereby realizing automatic cleaning of the filter cylinder.

The cam is fixedly installed on the outer side of the lower end of the connecting shaft. One end of the spring is fixedly installed on the inner wall of the cam, and the protrusion is fixedly installed on the other end of the spring.

[0014] Preferably, there are four striking mechanisms, which are distributed at equal angles inside the filter box.

[0023] The filtration mechanism is located inside the filter box 1, and the tapping mechanism is located inside the filter box 1.

[0024] The filtration mechanism includes a mounting plate 601, a top plate 602, a filter cylinder 603, a motor 604, a rotating shaft 605, a large gear 606, a connecting rod 607, a small gear 608, and a scraper 609.

The filter cylinder 603 is connected to the mounting plate 601. After water is introduced into the filter box 1 through the inlet pipe 4, as the water level rises, the water passes through the mounting plate 601 into the filter cylinder 603, is filtered by the filter cylinder 603, and then discharged and collected through the drain pipe 5, thus achieving water filtration. Multiple filter cylinders 603 are installed at equal angles between the mounting plate 601 and the top plate 602. The motor 604 is fixedly installed... The motor 604 (model 42BYGH48) is fixedly installed on the top of the inner wall of the filter box 1. The rotating shaft 605 is fixedly installed on the output end of the motor 604. The large gear 606 is fixedly installed on the outer side of the lower end of the rotating shaft 605.

By starting the motor 604, the rotating shaft 605 and the large gear 606 are driven to rotate. With the large gear 606 and the small gear 608 meshing, the connecting rod 607 drives the scraper 609 to rotate, cleaning the impurities on the inner wall of the filter cylinder 603, thus realizing the automatic cleaning of the filter cylinder 603.

[0026] In use, the water to be filtered is introduced into the filter box 1 through the inlet pipe 4. Under the action of gravity, impurities in the water will settle at the bottom of the filter box 1. At the same time, as the water level rises, the water will enter the filter cylinder 603 through the mounting plate 601 and be filtered by the filter cylinder 603. After passing through the filter cylinder 603, the water is discharged and collected through the drain pipe 5, thus achieving water filtration. When it is necessary to clean the filter cylinder 603, the motor 604 is started to drive the rotating shaft 605 and the large gear 606 to rotate. The large gear 606 meshes with the small gear 608, from... The connecting rod 607 drives the scraper 609 to rotate, cleaning the impurities on the inner wall of the filter cylinder 603. At the same time, when the connecting rod 607 rotates, it works with the pulley 702 and belt 703 to drive the connecting shaft 701 to rotate, causing the cam 704 to drive the protrusion 706 to rotate and intermittently impact the filter cylinder 603, causing the filter cylinder 603 to vibrate. This accelerates the shedding of impurities adhering to the inside of the filter cylinder 603, further improving the cleaning quality of the filter cylinder 603. Finally, the drain port 3 is opened to discharge the impurities inside the filter box 1.
