Description

Technical Field

[0001] This utility model relates to the fields of materials science and manufacturing technology, and in particular to a high-density metal filter screen. Background Technology

[0002] The purpose of high-density metal filters is to efficiently filter impurities and particles from fluids, ensuring fluid purity. Its significance lies in protecting equipment from wear and clogging in numerous industrial sectors such as chemical, food, and pharmaceutical industries, improving product quality, reducing malfunctions and defect rates caused by impurities, ensuring the stability and safety of the production process, and also helping to reduce maintenance costs and extend equipment lifespan.

[0003] High-density metal filters are commonly used in chemical, petroleum, pharmaceutical, and water treatment industries. In chemical production, they are used to filter materials after reactions; in the petroleum industry, they are used for fine filtration of crude oil; in pharmaceuticals, they ensure the purity of raw materials; and in water treatment, they remove minute impurities from water. Their working principle is based on the fine pores of the metal mesh. When fluid passes through, impurities larger than the pores are intercepted, while the fluid passes through smoothly, thus achieving solid-liquid separation or impurity filtration.

[0004] In existing technologies, some filter screens are fixed by screws and welding. Screw installation requires tools and is time-consuming, while welding is a permanent connection that is difficult to disassemble. This is not conducive to the regular cleaning, maintenance and replacement of the filter screen. When replacing or repairing the filter screen, disassembly will create a serious vacuum period, which will affect production efficiency. Therefore, a high-density metal filter screen is proposed to solve the above problems. Utility Model Content

[0029] 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.

[0030] Reference Figure 1 , Figure 3 and Figure 4 The present invention provides an embodiment of a high-density metal filter screen, comprising a mounting plate 1, which serves to support and fix other components, providing a foundation for the installation of the entire filter screen. A base plate 2 is detachably connected to the top of the mounting plate 1, which facilitates the installation and removal of the base plate 2, making it convenient for the maintenance and replacement of components of the filter screen. An mounting rod 11 is fixedly connected to the bottom of the base plate 2, which is used to connect and fix the base plate 2 to other components, serving as a support and positioning tool.

[0031] A limiting block 12 is fixedly connected to the bottom of the mounting rod 11. The limiting block 12 can restrict the movement of other components, ensuring the accuracy and stability of component installation. A sliding rod 9 is slidably connected to the inner wall of the mounting plate 1. The sliding rod 9 can slide on the inner wall of the mounting plate 1, thereby realizing position control of other components. A locking block 7 is fixedly connected to one end of the sliding rod 9. The locking block 7 is used to lock the limiting block 12 to fix the base plate 2. A return spring 8 is sleeved on the outer wall of the sliding rod 9. The return spring 8 can store and release elastic potential energy when the locking block 7 moves, playing a reset role, so that the locking block 7 can automatically return to its original position.

[0032] A control rod 10 is fixedly connected to the outer wall of the sliding rod 9. The control rod 10 is used to control the sliding of the sliding rod 9, which facilitates disassembly and installation by the operator. Multiple positioning rods 13 are fixedly connected to the bottom of the base plate 2. The positioning rods 13 are used to align with the mounting holes on the inner wall of the mounting plate 1 to achieve accurate installation and positioning of the base plate 2. The top of the locking block 7 is in contact with the outer wall of the limiting block 12. When the locking block 7 locks the limiting block 12, it can prevent the base plate 2 from moving and ensure the firmness of the installation. The outer wall of the control rod 10 is slidably connected to the inner wall of the mounting plate 1, so that the control rod 10 can slide on the inner wall of the mounting plate 1 for easy operation. One end of the return spring 8 is fixedly connected to the inner wall of the mounting plate 1 to provide a fixing point for the return spring 8 so that it can work normally. The outer wall of the positioning rod 13 is slidably connected to the inner wall of the mounting plate 1 to ensure that the positioning rod 13 can be accurately inserted into the mounting hole to achieve the positioning function.

[0033] Reference Figures 1 to 3 A filter frame 3 is fixedly connected to the top of the base plate 2. The filter frame 3 serves as a carrier for the metal mesh 4, plastic mesh 5, and high-density fiber mesh 6, integrating them. The high-density fiber mesh 6 is fixedly connected to the inner wall of the filter frame 3. The high-density fiber mesh 6 is used for fine filtration of the filter material, improving the filtration effect. The plastic mesh 5 is fixedly connected to the inner wall of the filter frame 3. The plastic mesh 5 can isolate and protect the fiber mesh, reduce filtration resistance, and optimize the overall performance of the filter. The bottom of the plastic mesh 5 and the top of the high-density fiber mesh 6 are in contact with each other, so that they are tightly combined and better perform their filtration function.

[0034] The inner wall of the filter frame 3 is fixedly connected with a metal mesh 4, which plays the main filtering role. Due to the characteristics of its material, it is adaptable to various environments. The metal mesh 4 is made of Monel alloy, which has strong corrosion resistance, high strength, and good wear resistance and high temperature resistance. The high-density fiber mesh 6 is made of polyethersulfone fiber and metal fiber. The polyethersulfone fiber high-density fiber mesh is resistant to high temperature and chemical corrosion, while the metal fiber is antistatic, which together improves the filtration effect and the scope of application. The plastic mesh 5 is made of polyvinyl chloride, which is flexible and wear-resistant. It can isolate and protect the fiber mesh, reduce filtration resistance, and optimize the overall performance of the filter.

[0035] Working principle: When the filter needs to be disassembled, slide the control lever 10. The sliding of the control lever 10 causes the sliding rod 9 to move to both sides. The movement of the sliding rod 9 causes the locking block 7 to move to both sides. At this time, the top of the locking block 7 is no longer in contact with the limiting block 12 at the bottom of the mounting rod 11. The filter can then be removed to complete the disassembly. When installation is required, align the positioning rod 13 with the mounting hole on the inner wall of the mounting plate 1 and insert it to complete the positioning. Then, the mounting rod 11 causes the limiting block 12 to slide inward into the mounting plate 1. Then, the two sides of the limiting block 12 contact the locking block 7. The locking block 7 retracts inward under the action of the return spring 8. When the limiting block 12 reaches the bottom of the locking block 7, the return spring 8 releases its elastic potential energy to lock the limiting block 12. This is how the filter is installed.

[0036] In the use of the filter screen, the filter screen frame 3 serves as the carrier of the metal mesh 4, and also plays an integrating role in the plastic mesh 5 and the high-density fiber mesh 6. The metal mesh 4 is made of Monel alloy, which has strong corrosion resistance, high strength, and good wear resistance and high temperature resistance. The high-density fiber mesh 6 is made of polyethersulfone fiber and metal fiber. The polyethersulfone fiber high-density fiber mesh is resistant to high temperature and chemical corrosion, while the metal fiber is antistatic, which together improves the filtration effect and the scope of application. The plastic mesh 5 is made of polyvinyl chloride, which is flexible and wear-resistant, can isolate and protect the fiber mesh, and can also reduce filtration resistance, thus optimizing the overall performance of the filter screen.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
