[0002] Precision security filters typically feature a stainless steel outer shell and internal tubular filter elements such as PP melt-blown, wire-burned, pleated, titanium, and activated carbon filters. Different filter elements are selected based on the specific filtration medium and design process to meet the required effluent quality. A quick-installation type is also available for convenient and quick filter element replacement and cleaning. This equipment is widely used in pharmaceutical, chemical, food, beverage, water treatment, brewing, petroleum, printing and dyeing, and environmental protection industries, making it an ideal device for filtering, clarifying, and purifying various liquids.

[0003] The publication number CN 223170482 U proposes a high-flow precision security filter that uses a single large-size filter element inside the cylinder for filtration. However, the effective filtration area within the limited cylinder volume is restricted, which leads to rapid filter element clogging, frequent replacement, and large system pressure drop under high load conditions. In addition, uneven water distribution can easily cause local filter elements to be overloaded while other filter elements are not fully utilized. The overall filtration efficiency and service life need to be improved.

[0004] Therefore, it is necessary to provide a new security filter based on high filtration area optimization to solve the above-mentioned technical problems. Utility Model Content

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a schematic diagram of the internal structure of the base in this utility model; Figure 3 This is a schematic diagram of the base structure in this utility model; Figure 4 This is a schematic diagram of the filter element in this utility model; Figure 5 This is a schematic diagram of the structure of the cylindrical body of this utility model. It includes: a base 1, a filter element 6, a cylindrical body 9, and a U-shaped ring tube 14.

[0018] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the base 1 has a water outlet chamber 2 inside, and a water outlet 4 communicating with the water outlet chamber 2 on one side of the base 1. The upper surface of the base 1 has multiple water outlet holes 3 arranged in a circular array, which communicate with the water outlet chamber 2. Multiple internally threaded tubes 5, each communicating with a water outlet hole 3, are fixedly connected to the upper surface of the base 1. Multiple filter elements 6 corresponding to the water outlet holes 3 are located above the base 1. An externally threaded tube 7 is located on the lower side of each filter element 6, with the lower end of the externally threaded tube 7 screwed into the corresponding internally threaded tube 5. A cylinder is fixedly connected to the upper surface of the base 1. The cylinder 9 has a water inlet 10 on its side and a drain outlet 11 on its side (the drain outlet 11 is connected to an automatic drain valve, which is an existing device and will not be described in detail here). A cover 12 is installed on the upper surface of the cylinder 9, and an exhaust outlet 13 is provided on the upper surface of the cover 12 (the exhaust outlet 13 is connected to an automatic exhaust valve, which is an existing device and will not be described in detail here). A U-shaped ring pipe 14 is fixedly connected to the inner side of the cylinder 9. The water inlet 10 is connected to the interior of the U-shaped ring pipe 14. The side of the U-shaped ring pipe 14 is provided with evenly distributed diversion holes 15.

[0019] It should be noted that during operation, the liquid to be filtered enters the U-shaped annular pipe 14 through the inlet 10 located at the top of the cylinder 9, and flows out evenly around the cylinder 9 through the evenly distributed diversion holes 15 on its side, achieving kinetic energy dissipation and uniform water distribution. The water then slowly and evenly penetrates all the filter elements 6 from bottom to top. Contaminants are trapped outside the filter elements 6, while the clean liquid enters the internal channels of the filter elements 6 and flows into the outlet chamber 2 of the base 1 through the external threaded pipe 7 at its bottom, and is finally discharged from the outlet 4. It should be further explained that the air generated during operation is discharged through the exhaust port 13 at the top of the cover 12, and the trapped pollutants can be periodically cleaned and discharged from the drain port 11, thus completing the entire filtration process.

[0020] refer to Figure 1As shown, two symmetrically arranged fixing plates 8 are fixedly connected to the side of the cylinder 9. The upper cover 12 is fixed to the fixing plate 8 by bolts, so that the upper cover 12 can be easily and quickly disassembled and assembled. A sealing gasket (not shown in the figure) is sandwiched between the cylinder 9 and the upper cover 12. This connection and sealing method is a conventional sealing method that is well known and commonly used by those skilled in the art and belongs to the prior art, so it will not be described in detail here.

[0021] refer to Figure 4 As shown, the lower end face of the externally threaded tube 7 is provided with an annular groove, and an O-ring 16 is fixedly connected in the annular groove. The inner diameter of the externally threaded tube 7 is the same as the inner diameter of the water outlet 3. By setting an annular groove on the end face of the externally threaded tube 7 and installing an O-ring 16, when the thread is tightened, the O-ring 16 is axially compressed, thus achieving a static seal between the end faces of the filter element 6 and the base 1. Secondly, by clearly defining that the inner diameter of the externally threaded tube 7 is the same as the inner diameter of the water outlet 3, it is ensured that the water outlet channel of the filter element 6 and the water inlet channel of the base 1 are smoothly transitioned and connected with equal diameter, avoiding eddies and local resistance caused by abrupt changes in diameter, thereby effectively reducing the head loss of the entire filtration system and improving the flow efficiency.

[0022] The filter element 6 is a melt-blown filter element. Melt-blown filter elements have the advantages of deep filtration, large pollutant capacity, and long service life. They also have good chemical stability and are suitable for large-scale use in applications where multiple elements are connected in parallel and need to be replaced regularly.

[0023] refer to Figure 1 As shown, the water inlet 10 is located at the top of the side of the cylinder 9, and the sewage outlet 11 is located at the bottom of the side of the cylinder 9, which conforms to the principles of fluid mechanics and maximizes the efficiency of operation and maintenance.

[0024] refer to Figure 2 and Figure 5 As shown, the horizontal plane where the axis of the U-shaped ring tube 14 is located is higher than the bottom of the filter element 6, so as to avoid water flow impacting the lower end of the filter element 6.

[0025] The working principle provided by this utility model is as follows: During operation, the liquid to be filtered enters the U-shaped ring pipe 14 from the inlet 10 located at the top of the cylinder 9, and flows out evenly along the circumference of the cylinder 9 through the evenly distributed diversion holes 15 on its side, thereby realizing the dissipation of kinetic energy and uniform water distribution. Water then flows slowly and evenly from bottom to top through all filter elements 6. Contaminants are trapped on the outside of filter elements 6, while clean liquid enters the internal channels of filter elements 6 and flows into the water outlet chamber 2 of the base 1 through the external threaded pipe 7 at its bottom, and is finally discharged from the water outlet 4. Air generated during operation is discharged from the exhaust port 13 at the top of the cover 12. The trapped contaminants can be periodically cleaned and discharged from the drain port 11, thus completing the entire filtration process. In summary, this utility model, by adopting a parallel structure of multiple filter elements 6 in a ring array, greatly increases the effective filtration area within the same equipment footprint, significantly increases the processing flow rate and lowers the pressure drop. The unique U-shaped ring pipe 14 lateral water distribution design ensures that water flow is distributed to each filter element 6, avoiding local short circuits or blockages, and significantly extending the service life of the filter elements 6.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
