Description

Technical Field

[0001] This utility model belongs to the field of water purification technology, specifically an automatic backwashing mesh filter that is easy to adjust on-site. Background Technology

[0002] Automatic backwashing mesh filters are highly efficient water treatment devices widely used in industry, water conservancy, agricultural irrigation, and swimming pool water treatment. Their working principle involves physically filtering solid particles and suspended matter from the water. Over time, the filter screen becomes clogged, and the backwashing device uses reverse water flow to clean the filter screen and restore its performance. In the future, automatic backwashing mesh filters will develop towards greater intelligence and energy efficiency, utilizing IoT technology and data analysis to achieve more efficient water treatment. These features make them play an increasingly important role in ensuring water quality and the normal operation of equipment.

[0003] However, many existing automatic backwashing mesh filters can only filter solid particles of a fixed size in actual use, lacking the flexibility to adjust the particle size. This can lead to several problems. First, the fixed mesh size can result in uneven filtration, failing to effectively capture large particles in different water qualities, thus affecting water quality standards and the operation of downstream equipment. Second, such equipment is prone to rapid clogging of the filter screen, increasing the frequency of backwashing and consequently raising the cost of maintenance and filter element replacement. Furthermore, the lack of flexibility makes it difficult to adapt to varying water quality conditions, reducing treatment efficiency and failing to meet diverse user needs. Simultaneously, operators may rely on experience to determine maintenance timing, leading to decision-making errors and missed optimal maintenance opportunities. Finally, this fixed design limits the equipment's application range and cannot meet the filtration requirements of specific industries or regulations.

[0004] Therefore, this utility model provides an automatic backwashing mesh filter that is easy to adjust on-site. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problem of the inability to flexibly adjust the size of filter particles, this utility model proposes an automatic backwashing mesh filter that is easy to adjust on-site.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model discloses an automatic backwashing mesh filter that is easy to adjust on-site. By rotating the first bolt, the adjusting cylinder rotates inside the filter cylinder. The square filter holes on the adjusting cylinder move in opposite directions, thus reducing the size of the pores. This allows for flexible adjustment according to different water quality conditions, ensuring optimal filtration and optimizing water treatment precision. Furthermore, this design enhances the applicability of the equipment, enabling it to adapt to various application scenarios and water sources, and is widely used in industrial, agricultural, and swimming pool fields. The adjustable pore size also reduces clogging frequency, decreases the need for backwashing, thereby reducing maintenance costs and equipment replacement frequency, and extending service life.

[0014] 2. The automatic backwashing mesh filter of this utility model, which is easy to adjust on-site, connects the connecting hole to the first connecting pipe and the second connecting pipe respectively by rotating the adapter plate. In cooperation with the control valve, it realizes the backwashing of the filter cylinder and the regulating cylinder, cleans out the filtered impurities, and discharges them through the bottom of the first bolt. This simplifies the backwashing process, and the structure is simple and easy to maintain. At the same time, by cooperating with the regulating cylinder, the regulating cylinder rotates inside the filter cylinder, thereby cleaning the attached solid particles and improving the cleaning efficiency.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Example 1:

[0025] like Figures 1 to 6As shown, the present invention provides an automatic backwashing mesh filter that is easy to adjust on-site. It includes a filter tube 3, with a sealing ring 32 fixedly connected to the bottom end of the filter tube 3, thus securing the sealing ring 32. A filter cylinder 31 is fixedly connected to the bottom inner side of the filter tube 3, also securing the filter cylinder 31. An adjusting cylinder 34 is rotatably connected to the inner side of the filter cylinder 31, limiting its position. The adjusting cylinder 34 is rotatably connected to the filter tube 3, limiting its top end and sealing the top end of the adjusting cylinder 34, thereby ensuring water flow. The filter flows out through the filter holes inside the filter cylinder 31 and the regulating cylinder 34. The bottom end of the regulating cylinder 34 is fixedly connected to the first bolt 33, which is limited by the regulating cylinder 34. The first bolt 33 is rotatably connected to the sealing ring 32, which also limits the first bolt 33. The inner side of the first bolt 33 is threaded with the second bolt 35, which is fixed by the first bolt 33. The second bolt 35 can be quickly disassembled through the thread between the first bolt 33 and the second bolt 35, which facilitates the cleaning of the filter cylinder 31 and the regulating cylinder 34. A connecting assembly is provided on the right side of the filter tube 3.

[0026] The adapter assembly includes a fixed plate 26, with a second connecting rod 25 fixedly connected to the top of the fixed plate 26, thus securing the second connecting rod 25. A limit ring 2 is fixedly connected to the top of the second connecting rod 25, securing the second connecting rod 25 and connecting the limit ring 2 and the fixed plate 26. A water inlet connector 1 is fixedly connected to the right side of the limit ring 2, securing the water inlet connector 1. A rotating ring 21 is rotatably connected to the outside of the limit ring 2, limiting the rotation ring 21. The left front end of the rotating ring 21... A first connecting rod 22 is fixedly connected and fixed by a rotating ring 21. A transfer plate 23 is fixedly connected to the right side of the first connecting rod 22. The rotating ring 21 and the transfer plate 23 are connected by the first connecting rod 22. Thus, by rotating the rotating ring 21, the first connecting rod 22 can drive the transfer plate 23 to rotate inside the limiting ring 2. The transfer plate 23 is rotatably connected to the limiting ring 2. A connection hole 24 is opened on the inner side of the transfer plate 23. When the transfer plate 23 is rotated, the connection hole 24 can be driven to rotate synchronously.

[0027] A second connecting pipe 28 is fixedly connected to the bottom left side of the fixing plate 26. The second connecting pipe 28 is fixedly connected to the filter pipe 3. A first connecting pipe 27 is fixedly connected to the top left side of the fixing plate 26. The fixing plate 26 simultaneously fixes the first connecting pipe 27 and the second connecting pipe 28.

[0028] The first connecting pipe 27 is fixedly connected to the left side of the first connecting pipe 4, and the fixed plate 26 and the first connecting pipe 4 are connected through the first connecting pipe 27. The bottom left side of the first connecting pipe 4 is fixedly connected to the second connecting pipe 41, which is fixedly connected to the filter pipe 3. The first connecting pipe 4 and the filter pipe 3 are connected through the second connecting pipe 41.

[0029] A control valve 42 is fixedly connected to the left side of the second connecting pipe 41, and the control valve 42 is fixed through the second connecting pipe 41.

[0030] The outer wall of the adapter plate 23 is provided with a rubber layer. By providing a rubber layer on the outside of the adapter plate 23, the adapter plate 23 and the limiting ring 2 are sealed and buffered at the same time.

[0031] Working principle: When the automatic backwashing mesh filter, which is easy to adjust on-site, is in operation, water first enters the filter tube 3 through the inlet connector 1, connecting hole 24, and second connecting pipe 28. Then, it enters the left cavity of the filter tube 3 through the filter holes on the regulating cylinder 34 and filter cylinder 31, and is then transported out through the second connecting pipe 41 and control valve 42. When cleaning the regulating cylinder 34 and filter cylinder 31, the control valve 42 is first closed. Then, the rotating ring 21 is rotated, and the first connecting rod 22 drives the adapter plate 23 to rotate inside the limit ring 2. Simultaneously, the adapter plate 23 drives the connecting hole 24 to rotate synchronously, connecting with the first connecting pipe 27. Then, the water flows through the inlet connector 1, the connecting hole 24, and the first connecting pipe 27 into the first connecting pipe 4, and then through the first connecting pipe 4 and the second connecting pipe 41 into the left cavity of the filter pipe 3. Finally, it enters the inside of the regulating cylinder 34 through the outside of the filter cylinder 31 and the regulating cylinder 34 to clean the impurities filtered from the inner walls of the regulating cylinder 34 and the filter cylinder 31. At the same time, the second bolt 35 is removed, and the water flows out through the second bolt 35, carrying away the impurities. In subsequent use, the first bolt 33 can be rotated to drive the regulating cylinder 34 to rotate, thereby increasing the friction between the filter cylinder 31 and the regulating cylinder 34 and accelerating the cleaning process.
