Description

Technical Field

[0001] This utility model relates to the field of filter components, and more specifically, it relates to a filter residual liquid filtration component with dual independent pipelines. Background Technology

[0002] After filtration, traditional filters leave some residual liquid at the bottom of the filter tank (hereinafter referred to as residual liquid). The residual liquid is usually filtered out by injecting compressed gas to pressurize the inside of the filter tank. However, the method of filtering residual liquid by pressurizing gas has the problem that the gas is discharged from the holes of the filter cartridge before reaching the bottom of the tank, resulting in insufficient pressure. Some residual liquid in the tank cannot be filtered, which affects the output of liquid.

[0003] To this end, application number 2024215857168 discloses a filter element that can improve the output of liquid. Under normal conditions, the liquid that has been filtered by the lower filter cartridge and enters the upper filter chamber is discharged through the notch of the central tube. After filtration, the accumulated liquid is discharged by injecting compressed gas. If there is still accumulated liquid at the bottom of the filter tank, the residual liquid that has been filtered by the lower filter cartridge and enters the lower filter chamber can be discharged through the sleeve to avoid the accumulation of liquid in the tank and affect the output of liquid.

[0004] However, the aforementioned residual liquid discharge structure can affect normal filtration. Specifically, during normal filtration, the filtrate needs to pass through the filter cartridge and enter the upper filter chamber, then flow into the central tube through the notch in the middle of the central tube and be discharged. Because the sleeve is nested inside the central tube and the central tube extends from the bottom of the sleeve, this structure directly occupies the internal flow space of the central tube—the effective flow area of ​​the central tube's cross-section is reduced due to the presence of the sleeve, affecting the normal filtration speed. In addition, the nested structure of the sleeve and the central tube may create a flow channel contraction effect near the notch, causing turbulence when the filtrate enters the central tube, further aggravating energy loss.

[0005] Therefore, in order to solve the above-mentioned technical problems, this application proposes a filter residual liquid filtration assembly with dual independent pipelines. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a filter residual liquid filtration assembly with dual independent pipelines.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a filter residual liquid filtration assembly with dual independent pipelines, including a filter tank for installing the filter assembly. The filter tank is internally divided into layers with multiple horizontally arrayed collecting pipes A and multiple collecting pipes B, forming a vertically isolated dual independent pipeline filtration system. The collecting pipes A are located above the collecting pipes B. The bottoms of the multiple collecting pipes A are interconnected with multiple main filter elements. The normal filtrate filtered by the main filter elements is discharged through the collecting pipes A. The bottoms of the multiple collecting pipes B are interconnected with multiple residual liquid discharge filter elements. The residual liquid discharge filter elements extend vertically downward to the bottom of the filter tank. The bottom residual liquid filtered by the residual liquid discharge filter elements is discharged through the collecting pipes B.

[0008] Preferably, the residual liquid filter element is located below the main filter element.

[0009] Preferably, the multiple manifolds A and multiple manifolds B are each independently installed on the filter tank.

[0010] Preferably, the filtration accuracy of the residual liquid filter element is higher than that of the main filter element.

[0011] Preferably, the bottom of the filter tank has a conical structure, and the residual liquid filter element is located at the lowest point of the conical structure.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This utility model forms a dual independent pipeline working mode of "normal filtration of the main filter element + special removal of residual liquid by the discharge filter element", which not only ensures that the flow rate of normal filtration is not affected by the sleeve structure, but also achieves efficient discharge of residual liquid through the special pipeline, so as to solve the problems in the background technology.

[0014] 2. This utility model, through its graded filtration system, is particularly suitable for the treatment of high-turbidity fluids in industries such as chemical and food processing. It achieves an optimized balance between filtration efficiency and operating costs while reducing the frequency of filter replacement.

[0015] 3. The bottom of the filter tank adapted to the filter assembly of this utility model is a conical structure, and the residual liquid discharge filter element on the filter assembly is located at the lowest point of the conical structure. This design breaks through the limitations of traditional flat-bottomed tanks and significantly improves filtration efficiency and cleanliness. Based on the principle of fluid dynamics, the optimized 60°-120° cone angle design can make full use of the component of gravity, so that the residual liquid can slide down the smooth cone surface at an accelerated speed, forming a stable laminar flow guide and eliminating dead corners where liquid stagnates.

[0022] like Figure 1-4 As shown, this utility model provides a filter residual liquid filtration assembly with dual independent pipelines, including a filter tank 1 for installing the filter assembly. The filter tank 1 has multiple horizontally arrayed manifolds A2 and B3 arranged in layers inside, forming a dual independent pipeline filtration system with vertical isolation. The manifolds A2 are located above the manifolds B3. The bottom of the multiple manifolds A2 are interconnected with multiple main filter elements 4. The filtrate filtered by the main filter elements 4 is discharged through the manifolds A2. The bottom of the multiple manifolds B3 are interconnected with multiple residual liquid discharge filter elements 5. The residual liquid discharge filter elements 5 extend vertically downward to the bottom of the filter tank 1. The bottom residual liquid filtered by the residual liquid discharge filter elements 5 is discharged through the manifolds B3.

[0023] In use, first input a sufficient amount of liquid to be filtered into the filter tank 1. Then, through a power device (such as a centrifugal pump), the liquid is applied to multiple manifolds A2, so that the liquid filtered by the main filter element 4 is discharged from the filter tank 1 through the manifolds A2 (normal filtration process). After filtration is completed, turn off the power device and pressurize the liquid in the filter tank 1 through the main filter element 4 by introducing compressed gas into the filter tank 1.

[0024] Meanwhile, under the action of compressed gas, the residual liquid discharge filter element 5 also filters the accumulated liquid that the main filter element 4 at the bottom of the filter tank 1 cannot filter, and discharges it through the collection pipe B3. That is to say, when the liquid that the main filter element 4 can handle is processed and gas is discharged, the residual liquid discharge filter element 5 may still be in a full liquid state. As long as there is a pressure supply of compressed gas in the filter tank 1, the liquid can continue to be filtered through the residual liquid discharge filter element 5 and discharged through the collection pipe B3, achieving a higher yield (i.e., filtering the residual liquid at the bottom of the filter tank that the main filter element cannot filter, thus improving the yield), and achieving less filter liquid accumulation in the filter tank 1, thereby preventing residual liquid from existing in the filter tank 1. In summary, this utility model forms a dual independent pipeline working mode of "normal filtration of the main filter element 4 + special removal of residual liquid by the residual liquid discharge filter element 5", which not only ensures that the flow rate of normal filtration is not interfered with by the sleeve structure, but also achieves efficient discharge of residual liquid through the special pipeline.

[0025] Furthermore, the main filter element 4 and the residual liquid discharge filter element 5 of this invention adopt an upper and lower distributed structure (the residual liquid discharge filter element 5 is located below the main filter element 4). The filtration accuracy of the residual liquid discharge filter element 5 needs to be higher than that of the main filter element 4, forming a two-stage filtration mechanism of "pretreatment-deep purification". The main filter element 4 uses a relatively loose filter medium (such as millimeter-level filter media) to take the lead in the preliminary filtration of large flow rates, rapidly reducing the turbidity of the fluid by intercepting most of the coarse particulate impurities (such as sand and sediment), significantly reducing the system load. The residual liquid discharge filter element 5 is equipped with a high-precision filter medium (such as micron-level filter membrane) to specifically treat the high-concentration residual liquid accumulated at the bottom of the tank. This design utilizes the gravity sedimentation characteristics of fluids, allowing denser impurities to naturally settle to the bottom, where the residual liquid discharge filter element 5 performs targeted fine filtration, effectively capturing tiny impurities such as colloids and microorganisms. Through this gradient filtration strategy, the service life of the main filter element 4 can be effectively extended, while the high-precision filtration of the residual liquid discharge filter element 5 also reduces the suspended solids content of the final filtrate, significantly improving the residual liquid recovery value and system operational stability. This tiered filtration system is particularly suitable for treating high-turbidity fluids in industries such as chemical and food processing. It reduces the frequency of filter replacement while achieving an optimal balance between filtration efficiency and operating costs.

[0026] Furthermore, the bottom of the filter tank 1 adapted to the filter assembly of this utility model is a conical structure, and the residual liquid discharge filter element 5 on the filter assembly is located at the lowest point of the conical structure. This design breaks through the limitations of traditional flat-bottomed tanks, significantly improving filtration efficiency and cleanliness. Based on the principle of fluid dynamics, the optimized 60°-120° cone angle design can make full use of the component of gravity, so that the residual liquid can slide down the smooth cone surface at an accelerated speed, forming a stable laminar flow guide and eliminating dead corners where liquid stagnates.

[0027] Moreover, the multiple manifolds A2 and B3 are all independently installed on the filter tank 1. The independent structure gives the system a high degree of maintainability. When a certain manifold is blocked or leaks, it can be disassembled and repaired or replaced separately without interrupting the entire filtration process, which greatly reduces downtime and maintenance costs.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
