Description

Technical Field

[0001] The utility model relates to the technical field of filter discs, in particular to a lightweight and high-flow filter disc. Background Technique

[0002] A filter disc, also called a disc filter or a disc type filter, is an industrial product with characteristics such as precise filtration, efficient backwashing, full-automatic operation, standard modularization, land saving, reliable operation, simple maintenance, and long service life. Its application in developed countries is quite common and it is widely used in water filtration in industries such as irrigation, wastewater treatment, sewage regeneration, municipal water supply, waterworks, large power plants, chemical industry, electric power, steel, machinery manufacturing, food and beverage processing, plastics, papermaking, mining, metallurgy, textile, petrochemical, environment, golf courses, automobiles, central air conditioning, etc., as well as in the field of seawater desalination pretreatment. In the filtration state, turbid water passes through the discs from the outside of the filter element. Under the action of spring force and hydraulic force, the filter discs are tightly pressed together, and impurity particles are intercepted at the intersection of the discs. The filtered clean water flows out of the filter.

[0003] After retrieval, in the prior art, the Chinese patent publication number: CN209828724U discloses a stacked filter sheet. The utility model includes: a filter assembly, a diversion ring, and a support spacer; the filter assembly is integrally in a circular ring structure, and a diversion ring is fixedly connected to its inner hole; support spacers are installed on both the upper and lower surfaces of the filter assembly; in a stacked filter sheet of the utility model, the plate body of the diversion plate in the filter sheet is corrugated, and all the filter cavities formed by the troughs on the upper and lower surfaces and the filter mesh are all connected through the convection holes thereon, so as to balance the pressure in all the filter cavities in the filter sheet, and can effectively prevent the phenomenon of backflow between the filter cavities to ensure the flow rate of the filter sheet.

[0004] However, this device still has the following defects:

[0005] The support spacer of this device will divide the surface of the filter sheet into multiple regions, making it difficult to carry out flushing. Moreover, the support spacer is higher than the surface of the filter membrane, which will block the water flow on the surface of the filter membrane, resulting in difficulty in flushing the impurity particles at the junction of the support spacer and the filter membrane. This device does not solve this problem. Content of the Utility Model

[0006] The purpose of the utility model is to provide a lightweight and high-flow filter disc. By arranging the support component inside the filter membrane, the outer surface of the filter membrane is made flat so as to facilitate flushing, and in cooperation with structures such as a telescopic ring, when the filter disc is loosened for flushing, it automatically pops outwards, making the distance between the filter discs larger, thereby improving the flushing effect to solve the problems raised in the above background technique.

[0015] Preferably, a plurality of centrally symmetric partition plates are arranged between the porous plates, and the top and bottom of the partition plates are respectively fixedly connected to the two porous plates.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] By arranging the support assembly inside the filter membrane, the present utility model has a simple structure, is convenient and practical, makes the outer surface of the filter membrane flat so as to facilitate flushing, and is used in conjunction with structures such as the telescopic ring.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 to 4 , the present invention provides a technical solution:

[0025] A lightweight and highly permeable filter disc, including a central ring 1. A plurality of groups of overflow troughs 2 are opened on the side wall of the central ring 1. Two groups of fixed plates 3 are fixedly installed at the top and bottom of the central ring 1. The bottom of the central ring 1 protrudes from the surface of the fixed plate 3. By setting the fixed plate 3, it is convenient to fix the filter membrane 7 and the perforated plate 6 to the central ring 1, improving the overall stability. At the same time, the bottom of the central ring 1 protrudes from the fixed plate 3, which can leave a gap between the filter discs when the filter discs are stacked and spiraled, so as to ensure that the filter membrane 7 is fully contacted with the water flow and improve the filtration efficiency; an activity groove 4 is opened at the bottom of the central ring 1, and a telescopic ring 5 is slidably installed in the activity groove 4. Four groups of slide bars 8 are arranged in the activity groove 4. The top of the slide bar 8 is fixedly connected to the top of the activity groove 4. The slide bar 8 is slidably matched with the telescopic ring 5. The bottom of the slide bar 8 is fixedly installed with a limit plate 9. The limit plate 9 is slidably matched with the telescopic ring 5. A spring 10 is slidably sleeved on the surface of the slide bar 8. The top of the spring 10 is fixedly connected to the top of the activity groove 4. The bottom of the spring 10 abuts against the top surface of the telescopic ring 5. A plurality of groups of baffles 11 are arranged at the bottom of the telescopic ring 5. The baffles 11 are fixedly connected to the telescopic ring 5. By setting the spring 10, the telescopic ring 5 and the baffle 11 can be pushed out downward. After the external force is removed, the gap between the stacked and spiraled discs can be increased, which is beneficial to flushing the surface of the filter disc. Then, in cooperation with the use of the baffle 11, the filter disc can be driven to rotate under the impact of the water flow, so that the surface of the filter disc is fully contacted with the water flow and the flushing effect is improved.

[0026] It also includes a support component. The support component is sleeved outside the central ring 1. The support component includes two groups of perforated plates 6. The perforated plates 6 are fixedly connected to the fixed plate 3. A plurality of groups of centrally symmetric partition plates 12 are arranged between the perforated plates 6. The top and bottom of the partition plates 12 are respectively fixedly connected to the two groups of perforated plates 6. It also includes a filtering component. The filtering component includes a filter membrane 7. The filter membrane 7 is arranged on the outer surface of the support component. The filter membrane 7 is fixedly connected to the support component. By using the perforated plates 6 and the partition plates 12 in cooperation with the central ring 1, it can replace the support spacer to play the role of support and ensure the gap, reduce the overall weight, and make the outer surface of the filter membrane 7 flat, thus facilitating flushing. At the same time, the channels formed between the partition plates 12 can well replace the flow dividing plate and the flow guiding plate to play the role of flow guiding, further reducing the overall weight, reducing the internal structure, reducing the resistance of the water flow, and thus improving the circulation efficiency.

[0027] During specific use, move this device to the designated position. Move the filter disc to align the central ring 1 with the water passing column of the external filter, and then sleeve it downwards. Perform the same operation to sleeve all the filter discs on the water passing column. Tighten the external tightening structure to tightly press the filter discs against each other, and then filtration can be carried out. When it is necessary to flush the filter discs, loosen the tightening structure. After the central ring 1 of the filter discs loses external force, the telescopic ring 5 and the baffle 11 at the bottom are pushed downwards by the spring 10, so that the distance between the filter discs becomes larger, thus facilitating the flushing of the filter discs. And the baffle 11 at the bottom of the telescopic ring 5 drives the filter discs to rotate on the external water passing column under the impact of the water flow, increasing the contact between the filter membrane 7 and the water flow, thereby improving the flushing efficiency.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
