Description

Technical Field

[0001] The utility model relates to the technical field of laminated filters, in particular to an automatic laminated backwashing filter with energy-saving and water-saving effects. Background Art

[0002] The laminated filter is a commonly used filtering device. Its working principle is to use the tiny gaps between the laminated plates to remove impurities in the water by physical interception. The principle of automatic backwashing of the laminated filter is realized through the built-in solenoid valve and control circuit. When the impurities in the filter accumulate to a certain extent, the control system will send a signal to open the solenoid valve to drain the water in the filter, and at the same time start the backwashing program, so that the laminated plates in the filter begin to rotate and wash away the filtered impurities from the laminated plates. In this way, the normal operation of the filter can be guaranteed and its service life can be extended.

[0003] Through patent search, it was found that the publication number is: CN220214132U, which discloses an automatic backwashing laminated filter. When the pressure of the water inlet pipe is greater than the set pressure of the water outlet pipe, the pressure switch sends a signal to the controller and sends a pulse signal. Since the pressure of the backflow water is greater than the pressure of the inlet water, the motor drives the blades to rotate at high speed, so that various debris accumulated on the surface of the laminated disc is scraped off, large pieces of sand and gravel are stirred and rotated, and the drain pipe is opened through the electromagnetic valve to be discharged. The above actions are repeated to backwash the first filter cylinder and other filters one by one. In this way, there is no need for manual disassembly and cleaning, and clean filtered water can always be provided during the filter cleaning process, thereby improving the working efficiency of the filter.

[0004] During use, the existing laminated filters need to be driven by water pressure to compress the filter laminates, which has a complex structure and is prone to malfunction, resulting in low pressure on the filter laminates. When backwashing the filter laminates, a large amount of clean water needs to be injected into the filter cartridge to backwash the filter laminates, resulting in a large amount of water resource waste. To solve the above problems, the present application proposes an automatic laminated backwashing filter with energy-saving and water-saving effects. Utility Model Content

A gear ring 15 is provided on the bottom surface of the supporting frame 5, and the gear ring 15 is meshed and connected with the driving gear 17.

[0028] It should be noted that, by controlling the extension of the electric telescopic rod 8, the electric telescopic rod 8 pushes the pressure cylinder 10 downward, and the pressure cylinder 10 is pressed on the top of the filter stack 7. By applying downward pressure to the filter stack 7, the filter stack 7 can be closely fitted together, the electric telescopic rod 8 shrinks, and the pressure on the filter stack 7 is cancelled. The pressing and unloading structure of the filter stack 7 is simple and more reliable to use. After a large amount of impurities are filtered out of the filter stack 7, clean water is injected into the filter cartridge 2 through the drain pipe 4, the electric telescopic rod 8 shrinks, and the pressure on the filter stack 7 is cancelled. At the same time, the support spring 13 is used to support the filter stack 7. The skeleton 5 is supported to separate the lower sealing ring 11 and the upper sealing ring 12. After the thickness of the driving gear 17 is greater than the ring gear 15, the ring gear 15 is still in meshing with the driving gear 17 after being lifted. The driving motor 16 drives the driving gear 17, and the driving gear 17 drives the ring gear 15 to rotate.

The fallen impurities can be discharged through the drain pipe 4. There is no need to inject a large amount of clean water to rinse the filter stack 7 during backwashing, which is more energy-saving and water-saving.

[0029] In this embodiment, if Figure 3As shown, the filter stack 7 is an outer circle center structure, and the middle part of the filter stack 7 abuts against the outer wall of the support frame 5.

[0030] It should be noted that the middle part of the filter stack 7 abuts against the outer wall of the support frame 5, so that the filter stack 7 and the support frame 5 can rotate together, and the filter stack 7 can be better washed.

[0031] In this embodiment, if Figure 4 As shown, a rotating seat 9 is rotatably provided at the piston rod end of the electric telescopic rod 8 , and the piston rod end of the electric telescopic rod 8 is rotatably connected to the pressing cylinder 10 through the rotating seat 9 .

The top of the support spring 13 is rotatably connected to a rotating bearing 14, and the top of the rotating bearing 14 is connected to the lower surface of the upper sealing ring 12.

[0036] It should be noted that the support spring 13 applies an upward thrust to the support frame 5 to separate the lower sealing ring 11 and the upper sealing ring 12. When the support frame 5 rotates, the support spring 13 does not rotate with the support frame 5 through the rotating bearing 14.

Water is injected into the filter cartridge 2 through the liquid inlet pipe 3. The water is located between the inner wall of the filter cartridge 2 and the outer wall of the filter stack 7. The water passes through the cavity wall of the filter stack 7 to filter the water. The filtered water enters the inner cavity of the support frame 5 and is discharged from the drain pipe 4 at the bottom. After a large amount of impurities are filtered out of the filter stack 7 , clean water is injected into the filter cartridge 2 through the drain pipe 4, the electric telescopic rod 8 contracts, the pressure on the filter stack 7 is removed, and the support frame 5 is supported by the support spring 13, so that the lower sealing ring 11 and the upper sealing ring 12 can be separated.

The ring gear 15 drives the filter stack 7 to rotate at a high speed in the filter cartridge 2 through the support frame 5, so as to realize backwashing of the filter stack 7, and the fallen impurities can be discharged through the drain pipe 4. There is no need to inject a large amount of clean water to rinse the filter stack 7 during backwashing, which is more energy-saving and water-saving.
