Description

Technical Field

[0001] This utility model relates to the field of blade filter technology, and in particular to a filter channel cleaning structure for a blade filter. Background Technology

[0002] A filter is a device used for filtration. Horizontal leaf filters are widely used in the food and chemical industries. However, the filter plates of existing horizontal leaf filters often retain a lot of impurities after filtration. Disassembling and cleaning the filter plates is inconvenient, and the impurities on the filter plates can easily cause blockage, affecting the filtration effect of the filter and causing problems.

[0003] Currently, patent number CN218306543U discloses a horizontal blade filter that is easy to clean, including a main body and a base. The main body is fixedly mounted on the base, and a top cover is fixedly mounted on the top of the main body. A first partition is fixedly mounted inside the main body, and a second partition is movably mounted through the inner and outer walls of the first partition at one end, and the second partition is slidably connected to the first partition and the main body. A filter plate is fixedly mounted between the main body and the first partition, and the filter plate is wrapped by the main body, the first partition, and the second partition. A through groove is fixedly mounted below the filter plate on the base, and a storage box is movably mounted below the through groove. A sliding groove is fixedly opened inside the through groove, and a bottom plate is slidably mounted inside the sliding groove. A fifth groove is opened in the middle of the base, and a motor is fixedly mounted inside the fifth groove. A gear is fixedly mounted on the output shaft of the motor. In this utility model, the main unit can be operated normally while achieving the effect of easy cleaning.

[0004] While the aforementioned easy-to-clean horizontal leaf filter can clean the filter plates using water pipes and nozzles, the fixed positions of these pipes and nozzles mean that the nozzles can only effectively clean the upper part of the filter plates, leaving the middle and lower parts uncleaned. This insufficient cleaning power can lead to the accumulation of dirt and impurities in these areas. Furthermore, since the water pipes and nozzles are installed on the inner wall of the filter body, they are directly exposed to the filter media and susceptible to corrosion. This corrosion not only causes nozzle clogging and reduces cleaning effectiveness but also shortens the lifespan of the water pipes and nozzles, increasing maintenance costs and downtime. Therefore, this fixed cleaning system has significant shortcomings in practical applications and requires further improvement to enhance the cleaning performance and reliability of the filter. Utility Model Content

[0005] The purpose of this invention is to provide a filter channel cleaning structure for a blade filter. This filter channel cleaning structure solves the problem that fixed water pipes and nozzles can only effectively rinse the upper part of the filter plate, while the middle and lower parts of the filter plate are difficult to clean thoroughly, resulting in insufficient cleaning power and potentially leading to the accumulation of dirt and impurities in these areas.

[0006] This utility model provides a filter channel cleaning structure for a leaf filter, including a base and a filter body. The filter body is fixedly mounted on the top of the base. The filter body includes a housing and multiple filter plates. The housing is fixedly mounted on the top of the base, and the multiple filter plates are fixedly mounted inside the housing, arranged sequentially from left to right. A spray bracket is fixedly mounted on the top of the housing, and two support seats are fixedly mounted on the top of the spray bracket. A water guide pipe is fixedly mounted between the two support seats. A water inlet pipe is fixedly connected to the top of the water guide pipe, and the water guide pipe and the water inlet pipe are connected.

The multiple water distribution pipes are all fixedly connected through the top of the spray bracket. The other end of the multiple water distribution pipes is fixedly connected to a number of movable spray structures equal to the number of filter plates. Each filter plate corresponds to one movable spray structure. The bottom of the housing is provided with a number of sewage discharge components equal to the number of movable spray structures.

[0007] Preferably, the mobile spray structure includes a telescopic cylinder, a spray pipe, multiple spray heads, and a corrugated telescopic pipe. The telescopic cylinder is fixedly installed at the top inside the spray support. The spray pipe is fixedly installed at the drive end of the telescopic cylinder. The multiple spray heads are fixedly installed on the spray pipe and are located on the side close to the filter plate. One end of the corrugated telescopic pipe is connected to the other end of the water distribution pipe, and the other end of the corrugated telescopic pipe is connected to the spray pipe. The corrugated telescopic pipe is located behind the telescopic cylinder.

[0008] Preferably, the mobile spray structure further includes a connecting seat and a sealing plate. The top of the housing has a channel opening. The spray pipe and spray head can move vertically in a straight line within the channel opening under the drive of the telescopic cylinder. The connecting seat is fixedly installed at the bottom of the spray pipe, and the sealing plate is fixedly installed at the bottom of the connecting seat, with the sealing plate located inside the channel opening.

[0009] Preferably, the movable spray structure further includes a sealing gasket, which is fixedly fitted onto the sealing plate and in close contact with the channel opening.

[0010] Preferably, the spray pipes are arranged parallel to the filter plate, and the plurality of spray heads are evenly distributed along the length of the spray pipes.

[0016] This invention provides an improved filter channel cleaning structure for a leaf filter, offering the following improvements and advantages compared to existing technologies: Firstly, the movable spray structure, driven by a telescopic cylinder, allows the spray pipes and heads to move linearly up and down within the filter body. This enables comprehensive rinsing of the filter plates, including the upper, middle, and lower sections, solving the problem of fixed spray heads only rinsing the upper part of the filter plate. This ensures effective removal of dirt and impurities from the entire filter plate surface, improving cleaning uniformity and filtration efficiency. Secondly, the evenly distributed spray head design ensures that water flow evenly covers the entire filter plate, avoiding cleaning dead zones and further enhancing the cleaning effect. Thirdly, when not rinsing, the spray pipes and heads can be sealed at the filter body's channel openings by matching the sealing plate with the channel opening. This effectively prevents filtered impurities from directly contacting the spray system, reducing the corrosive effect of the medium on the spray system, avoiding nozzle clogging, extending the service life of the spray system, and reducing maintenance costs and downtime.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a filter channel cleaning structure for a leaf filter, including a base 1 and a filter body 2. The filter body 2 is fixedly installed on the top of the base 1. The filter body 2 includes a housing 21 and multiple filter plates 22. The housing 21 is fixedly installed on the top of the base 1, and the multiple filter plates 22 are fixedly installed inside the housing 21, arranged sequentially from left to right. The core part of the housing 21 is composed of multiple filter plates 22. This is existing equipment in the field, so it will not be described in detail here. A spray bracket 3 is fixedly installed on the top of the housing 21. Two support seats 4 are fixedly installed on the top of the spray bracket 3. A water guide pipe 5 is fixedly installed between the two support seats 4. The support seats 4 support the water guide pipe 5. A water inlet pipe 6 is fixedly connected to the top of the water guide pipe 5. The components are connected to each other. The inlet pipe 6 is also connected to an external water supply device. The inlet pipe 6 is used to transport external water to the water guide pipe 5. The bottom of the water guide pipe 5 is fixedly provided with one end of multiple water distribution pipes 7. The water guide pipe 5 is used to evenly distribute the rinsing water to each water distribution pipe 7. The multiple water distribution pipes 7 are fixedly connected to the top of the spray bracket 3. The other end of the multiple water distribution pipes 7 is fixedly connected to a number of mobile spray structures 8 that are the same as the number of filter plates 22. Each water distribution pipe 7 is used to distribute water to one mobile spray structure 8. Each filter plate 22 corresponds to one mobile spray structure 8. Each mobile spray structure 8 is used to rinse one filter plate 22. The bottom of the casing 21 is provided with a number of sewage discharge components 9 that are the same as the number of mobile spray structures 8. The sewage discharge components 9 are opened when the mobile spray structures 8 are rinsing, and they are used to discharge the sewage generated during rinsing.

[0029] Specifically, the mobile spray structure 8 includes a telescopic cylinder 81, a spray pipe 82, multiple spray heads 83, and a corrugated telescopic pipe 84. The telescopic cylinder 81 is fixedly installed at the top of the spray support 3. The spray pipe 82 is fixedly installed at the drive end of the telescopic cylinder 81. The telescopic cylinder 81 is used to drive the spray pipe 82 to move vertically. Multiple spray heads 83 are fixedly installed on the spray pipe 82 and are located on the side close to the filter plate 22. The spray heads 83 spray in a divergent manner. One end of the corrugated telescopic pipe 84 is connected to the other end of the water distribution pipe 7, and the other end of the corrugated telescopic pipe 84 is connected to the spray pipe 82. The corrugated telescopic pipe 84 can extend and retract accordingly according to the extension and retraction of the telescopic cylinder 81 to ensure the normal operation of the spray pipe 82. The corrugated telescopic pipe 84 is located behind the telescopic cylinder 81.

[0030] Specifically, the mobile spray structure 8 also includes a connecting seat 85 and a sealing plate 86. The top of the housing 21 has a channel opening. The spray pipe 82 and the spray head 83 can move vertically up and down in the channel opening under the drive of the telescopic cylinder 81. The connecting seat 85 is fixedly set at the bottom of the spray pipe 82, and the sealing plate 86 is fixedly set at the bottom of the connecting seat 85. The sealing plate 86 is located inside the channel opening and is used to seal the channel opening to prevent the filter medium from corroding the spray pipe 82 and the spray head 83.

[0031] Specifically, the movable spray structure 8 also includes a sealing gasket 87, which is fixedly fitted onto the sealing plate 86 and is in close contact with the channel opening. The sealing gasket 87 is used to seal the gap between the sealing plate 86 and the channel opening, further improving the sealing effect of the sealing plate 86.

[0032] Specifically, the spray pipe 82 is arranged parallel to the filter plate 22, and multiple spray heads 83 are evenly distributed along the length of the spray pipe 82. The evenly distributed spray heads 83 can ensure that water is sprayed onto the filter plate 22 in a comprehensive manner, thereby rinsing the filter plate 22 without dead angles.

[0033] Specifically, the sewage discharge assembly 9 includes a sewage discharge pipe 91 and a solenoid valve 92. A sewage discharge port is provided at the bottom of the housing 21, and an opening is provided on the base 1. The sewage discharge pipe 91 is fixedly installed at the sewage discharge port, and the solenoid valve 92 is fixedly connected to the sewage discharge pipe 91. Both the sewage discharge pipe 91 and the solenoid valve 92 are located at the opening of the base 1. The sewage discharge pipe 91 is used to discharge the wastewater generated by the mobile spray structure 8 during rinsing, and the solenoid valve 92 controls the opening and closing of the sewage discharge pipe 91.

[0034] Specifically, an inverted cone structure is provided in the middle part of the sewage pipe 91, which helps to improve the discharge efficiency of the sewage pipe 91.

[0035] Specifically, a sewage collection tank 10 is provided below the base 1. The top of the sewage collection tank 10 is open and the sewage collection tank 10 is located below the sewage pipe 91. The sewage collection tank 10 is used to collect sewage discharged from the sewage pipe 91.

[0036] Specifically, a recycling filter 11 is also fixedly installed inside the sewage collection tank 10. The recycling filter 11 is used to filter impurities in the sewage, so that the filtered water can be reused.

[0037] Specifically, the filter body 2 also includes an inlet 23 and an outlet 24. One end of the inlet 23 is fixedly connected to the left side of the casing 21, and one end of the outlet 24 is fixedly connected to the right side of the casing 21. The medium to be filtered enters through the inlet 23, is filtered by the filter plate 22, and is discharged through the outlet 24.

[0038] Working principle: The medium to be filtered enters the housing 21 through the inlet 23. As it flows through multiple filter plates 22, solid particles are intercepted by the filter plates 22, while the filtered clear liquid is discharged from the outlet 24. During the filtration process, solid particles gradually accumulate on the filter plates 22, so they need to be cleaned regularly.

[0039] During cleaning, the operation of the filter body 2 is stopped, and the external water supply equipment delivers water to the guide pipe 5 through the inlet pipe 6. The water is then distributed to each mobile spray structure 8 through multiple branch pipes 7 at the bottom of the guide pipe 5.

[0040] In the movable spray structure 8, the telescopic cylinder 81 drives the spray pipe 82 and the sealing plate 86 to move downwards. After the channel opening blocked by the sealing plate 86 is opened, the spray pipe 82 and the spray head 83 can move up and down repeatedly within the housing 21. At this time, the multiple spray heads 83 fixed on the spray pipe 82 can perform all-round rinsing of the corresponding filter plate 22. During the rinsing process, the evenly distributed design of the spray heads 83 ensures that the water flow can fully cover the filter plate 22, achieving cleaning without dead angles.

[0041] During rinsing, the solenoid valve 92 in the sewage discharge assembly 9 opens, and the sewage discharge pipe 91 discharges the wastewater generated during rinsing to the sewage collection tank 10. The recycling filter screen 11 in the sewage collection tank 10 filters impurities in the sewage to achieve water reuse.

[0042] During non-rinsing periods, the sealing plate 86 returns to its original position under the action of the telescopic cylinder 81, sealing the channel opening and preventing the filter medium from corroding the spray pipe 82 and spray head 83. At the same time, the sealing gasket 87 further ensures the sealing effect of the blockage, avoiding media leakage and corrosion problems, thereby extending the service life of the equipment.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
