Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a plate filter with stable application. Background Technology

[0002] Stable plate filters are specialized equipment used for liquid filtration in the fields of water treatment and fluid purification. This equipment, through the cooperation of components such as disc assemblies and coarse filtration devices, performs graded filtration of impurities in liquids, removing contaminants of different particle sizes, ensuring the cleanliness of the filtered liquid. It is suitable for various scenarios such as industrial water treatment, municipal water supply purification, and chemical fluid filtration, providing support for quality control of liquids in production and daily life.

[0003] Traditional plate filters have significant shortcomings in terms of filtration accuracy and efficiency. Most filters rely solely on a single stacked disc fine filtration structure, lacking a progressive coarse filtration stage. High-concentration impurities in the raw liquid directly enter the disc channels, easily clogging the tiny channels and causing a sharp drop in filtration efficiency. This necessitates frequent backwashing, increasing energy consumption and affecting filtration continuity. Furthermore, some filters lack stable fixing and guiding structures for the discs, leading to misalignment during stacking and uneven flow channels. This makes it impossible to precisely control filtration accuracy, and some oversized impurities may penetrate the channels, affecting the quality of the filtered liquid. In addition, existing filters have poor flexibility in adjusting filtration accuracy, making it difficult to adjust the filtration level according to the purification needs of different liquids. This results in low adaptability and fails to meet the requirements of "high accuracy, high efficiency, and low maintenance" for liquid filtration in various scenarios. Therefore, we propose a stable plate filter. Utility Model Content

[0004] One of the technical problems this application aims to solve is that existing water treatment filters rely solely on a single disc fine filtration structure, lacking a progressive coarse filtration stage. This makes them prone to rapid clogging of microchannels, leading to a sharp decline in filtration efficiency and affecting the continuity of filtration.

[0005] To address the aforementioned technical problems, this application provides a stable plate filter, comprising a support bracket, a support block fixedly connected to one outer wall of the upper end of the support bracket, an infusion tube fixedly connected to the outer wall of the upper end of the support block, a connecting valve fixedly connected to the outer wall of the upper end of the infusion tube, a connecting block fixedly connected to the outer wall of the upper end of the connecting valve, a housing connected to one outer wall of the upper end of the connecting block, a limiting member fixedly connected to the middle of the inner wall of the connecting block, a water collection cavity connected to one side of the inner wall of the limiting member, a plurality of stacked plates movably connected to one outer wall of the limiting member, a connecting groove formed in the middle of the inner wall of the stacked plates, a plurality of concave and convex textures fixedly connected to the outer walls of both the upper and lower ends of the stacked plates, and a limiting block engaged with the outer wall of the upper end of the limiting member.

[0006] In some embodiments, a caster wheel is connected to the lower outer wall of the bracket, a first connecting pipe is connected to one outer wall of the housing, a coarse filter is fixedly connected to the side of the first connecting pipe away from the housing, a display is fixedly connected to one outer wall of the upper end of the coarse filter, a second connecting pipe is connected to one outer wall of the upper end of the coarse filter, a pump is fixedly connected to one side of the second connecting pipe, and a limit ring is connected to one outer wall of the bracket.

[0007] In some embodiments, the upper end of the stacked pieces and the outer wall of the upper end of the limiting member are both connected to the lower end of the limiting block.

[0008] In some embodiments, the connecting groove on one side of the inner wall of the stacked pieces is connected to the corresponding outer wall of the limiting member.

[0009] In some embodiments, a plurality of concave and convex textures are provided between the plurality of stacked sheets.

[0010] In some embodiments, one side of the outer wall of the laminate is close to the connecting block and the inner wall of the housing.

[0011] In some embodiments, the coarse filter is movably connected to the outer wall of one side of the upper end of the support, and the coarse filter is correspondingly connected to the inner wall of the limiting ring provided on one side of the outer wall of the support.

[0012] In some embodiments, the first connecting pipe is T-shaped and connects multiple coarse filter devices and the housing in series.

[0013] This utility model has at least the following beneficial effects: In use, this invention improves filtration accuracy and efficiency by combining the disc assembly, coarse filtration device, and water collection chamber to form a dual filtration structure of "coarse filtration + fine filtration," significantly optimizing the filtration effect. In the fine filtration stage, multiple discs are fixed to the internal wall via connecting grooves and limiting components. The interlocking textures at the upper and lower ends of the discs form uniform microchannels of 5-100μm (accuracy can be adjusted by replacing the discs). As the liquid flows through, impurities larger than the channel size are intercepted, while qualified liquid permeates into the central water collection chamber, achieving precise fine filtration. Simultaneously, three coarse filtration devices connected in series between the connecting block and the housing form a progressive coarse filtration system via a second connecting pipe, reducing the turbidity of the original liquid from above 50 NTU to below 10 NTU before entering the fine filtration stage. This dual filtration design thoroughly alleviates the clogging pressure on the discs, preventing high-concentration impurities from clogging the channels within 1-2 hours, reducing backwashing frequency, lowering energy consumption, and significantly improving filtration efficiency. In addition, the limiting block fixes the stacked discs and the limiting component guides the stacked discs, ensuring that the discs are stacked neatly and without deviation, guaranteeing the uniformity of the flow channel, and further maintaining stable filtration accuracy. In use, this invention achieves uninterrupted water supply through the coordinated operation of multiple devices and backwash control, ensuring continuous water output and operational stability. The device is equipped with multiple filters with casters, and the devices alternately perform filtration and backwashing via connecting valves. When one group of devices initiates backwashing to restore filtration capacity, the other devices operate normally, avoiding water interruption during backwashing, reducing the operating load on individual devices, and extending their service life. The pump provides stable power to the entire filtration system, ensuring a continuous delivery of the raw material to the coarse and fine filtration stages, preventing filtration stagnation due to insufficient pressure. The display at the top of the coarse filtration unit allows real-time monitoring of the internal filtration status, facilitating operators to determine whether the raw material meets the fine filtration standards, proactively identifying potential blockages, and ensuring a continuous and stable filtration process.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: Please refer to Figure 1-5This utility model provides a technical solution: a stable plate filter, including a support 1, a support block 3 fixedly connected to one outer wall of the upper end of the support 1, an infusion tube 4 fixedly connected to the upper outer wall of the support block 3, a connecting valve 5 fixedly connected to the upper outer wall of the infusion tube 4, a connecting block 6 fixedly connected to the upper outer wall of the connecting valve 5, a housing 7 connected to one outer wall of the upper end of the connecting block 6, a limiting member 8 fixedly connected to the middle of the inner wall of the connecting block 6, a water collection cavity 9 connected to one side of the inner wall of the limiting member 8, and multiple... Each stacked piece 10 has an outer wall side close to the connecting block 6 and the inner wall of the housing 7. A connecting groove 11 is provided in the middle of the inner wall of the stacked piece 10. The connecting groove 11 on one side of the inner wall of the stacked piece 10 is connected to the outer wall side of the limiting member 8. Multiple concave and convex textures 12 are fixedly connected to the outer walls of both the upper and lower ends of the stacked piece 10. Several concave and convex textures 12 are provided between the multiple stacked pieces 10 and are connected to each other. A limiting block 13 is engaged on the upper outer wall of the limiting member 8. The upper end of the stacked piece 10 and the upper outer wall of the limiting member 8 are connected to the lower end of the limiting block 13.

[0018] In this embodiment, a support 1 is designed, and an infusion tube 4 is fixedly connected to one side of the upper end of the support 1 via a support block 3. A connecting block 6 is fixedly connected to the upper end of the infusion tube 4 via a connecting valve 5. A housing 7 is connected to the upper outer wall of the connecting block 6, and the connecting block 6 and the housing 7 form an outer shell. A limiting member 8 is fixedly connected to the middle of its inner wall. A water collection cavity 9 is provided on one side of the inner wall of the limiting member 8, and multiple stacked pieces 10 are movably connected to one side of the outer wall of the limiting member 8. These pieces are stacked on top of each other, and multiple concave and convex textures 12 are provided on the outer walls of both the upper and lower ends of the stacked pieces 10. Therefore, the stacked pieces 10 are connected to each other. Several overlapping textured surfaces 12 are arranged on the stacked sheets 10. A connecting groove 11 is provided in the middle of the inner wall of the stacked sheets 10. The connecting groove 11 can be used to limit the connection between the stacked sheets 10 and the outer wall of the limiting member 8. The multiple stacked sheets 10 can cover the water collection cavity 9. Thus, when the filtration operation is performed, water will permeate from the inner wall of the connecting block 6 and the housing 7 through the pressure difference into the stacked sheets 10 and the water collection cavity 9. At this time, the overlapping textured surfaces 12 are provided between the stacked sheets 10. The overlapping textured surfaces 12 interlock with each other to form a uniform "micro-channel" (the channel width is the filtration accuracy, usually 5-100μm, which can be adjusted by selecting...). (Adjusting different textured laminates 10), when liquid enters the tiny flow channels between the laminates 10, particles smaller than the impurity particle size (such as mud, colloids, and suspended solids) are intercepted at the inlet or inside of the flow channels, while liquid meeting the required precision permeates through the flow channels to the water collection chamber 9 at the center of the laminate 10 group. At this point, it can be conveyed downwards through the water collection chamber 9 and transmitted to the infusion pipe 4 via the connecting valve 5. Then, the clean liquid is discharged from the infusion pipe 4, completing the filtration. A limiting block 13 is provided at the upper end of the limiting member 8 and the laminate 10. The limiting block 13 engages with the limiting member 8 and the limiting block 13, thereby enabling [filtration / filtering]. The limiting device fixes multiple stacked discs 10 to one side of the outer wall of the limiting component 8, and they are stacked on top of each other to prevent displacement. As filtration continues, the impurities intercepted between the stacked discs 10 will gradually accumulate, causing the pressure difference between the inlet and outlet to increase (usually a "pressure difference threshold" is set, such as 0.05MPa). At this time, backwashing needs to be started to restore the filtration capacity. Backwashing is an existing technology, so it will not be elaborated on. This type of filter is equipped with two casters, which are connected to the valve 5 to control alternating filtration / backwashing (when one group is backwashed, the other groups are operating normally), ensuring continuous and stable effluent while reducing the load on a single unit.

[0019] Example 2: Please refer to Figure 1-2A caster wheel 2 is connected to the lower outer wall of the bracket 1. A first connecting pipe 14 is connected to one side of the outer wall of the housing 7. A coarse filter device 15 is fixedly connected to the side of the first connecting pipe 14 away from the housing 7. The first connecting pipe 14 is T-shaped and connects multiple coarse filter devices 15 and the housing 7 in series. A display 16 is fixedly connected to one side of the upper outer wall of the coarse filter device 15. A second connecting pipe 17 is connected to one side of the upper outer wall of the coarse filter device 15. A pump 18 is fixedly connected to one side of the second connecting pipe 17. A limit ring 19 is connected to one side of the outer wall of the bracket 1. The coarse filter device 15 is movably connected to one side of the upper outer wall of the bracket 1, and the coarse filter device 15 is correspondingly connected to the inner wall of the limit ring 19 on one side of the outer wall of the bracket 1.

[0020] In this embodiment, because the "deep filtration" capability of this type of plate filter is limited, high-concentration impurities quickly clog the flow channels of the stacked plates 10, exceeding its load limit. This results in backwashing within 1-2 hours when the turbidity of the treated raw liquid exceeds 50 NTU (such as industrial wastewater or river water). Frequent backwashing leads to increased energy consumption and reduced effluent efficiency. Therefore, three coarse filtration devices 15 are provided before the connecting block 6 and the housing 7. The three coarse filtration devices 15 are connected in series through the second connecting pipe 17, and every two coarse filtration devices 15 are connected to the connecting block 6 and the housing 7 through the first connecting pipe 14. This can reduce the turbidity of the raw liquid to below 10 NTU before it enters the connecting block 6 and the housing 7 for filtration. This greatly improves filtration efficiency. A pump 18 is connected to one side of the second connecting pipe 17. The pump 18 can drive the device to operate and draw up the liquid. A display 16 is provided at the upper end of the coarse filter device 15. The display 16 can intuitively observe the filtration status inside the coarse filter device 15, thereby determining whether to allow it to enter the connecting block 6 and the housing 7 for filtration. A caster wheel 2 is provided at the lower end of the bracket 1. The caster wheel 2 can drive the device to move in different positions and can be applied to different scenarios. A limiting ring 19 is provided on one side of the upper end of the bracket 1. The limiting ring 19 can limit the coarse filter device 15 to prevent it from shifting during transportation.
