Description

Technical Field

[0001] This utility model relates to the field of combined screens, and in particular to an improved combined metal screen. Background Technology

[0002] Modular metal screens are high-efficiency screening tools composed of multiple parts, typically including a screen frame, screen plate, connecting components, and support components. The screen frame, as the supporting structure of the entire screen, is designed to be robust and durable, capable of withstanding the weight of large materials and the impact forces during the screening process. The screen plate is made of metal, such as stainless steel, which has excellent wear resistance and corrosion resistance, ensuring that the screen openings remain clear and screening efficiency is maintained for a long time. The connecting components and support components are responsible for firmly connecting the screen plate to the screen frame, ensuring the stability and reliability of the screen.

[0003] While current modular metal screens, by assembling multiple circular screens, can enhance their screening efficiency and expand their applicability in practical use, each screen unit occupies a certain volume. When storage is required, these screen units often cannot be tightly stacked, resulting in a large overall storage space requirement. This not only increases storage costs but also causes inconvenience in transportation and carrying.

[0004] The assembly and disassembly process of modular metal screens is relatively cumbersome. Before storage, each screen unit needs to be disassembled one by one, which is not only time-consuming and labor-intensive but also prone to damaging the screen during disassembly. When needed, the screen units must be reassembled, which also requires time and effort. This cumbersome assembly and disassembly process reduces the efficiency of the screen and increases operating costs. Utility Model Content

[0005] The main objective of this invention is to provide an improved combined metal screen that can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An improved combined metal screen includes a first elastic metal support frame and a second elastic metal support frame; The first elastic metal support frame and the second elastic metal support frame have the same structure. The first elastic metal support frame includes a lateral ring and an elastic metal strip. The two ends of the elastic metal strip are provided with lateral rings. The lateral rings are provided with notches, and the notches are provided with mating protrusions. The two mating protrusions are fixed by fasteners. The outer end of the lateral ring is equipped with a connecting flange, and the end face of the connecting flange is provided with multiple connecting holes. The first elastic metal support frame and the second elastic metal support frame are assembled by connecting flange, connecting holes and bolts. An installation chamber is formed between the elastic metal strip and the lateral ring. A first metal screen is installed in the installation chamber of the first elastic metal support frame, and a second metal screen is installed in the installation chamber of the second elastic metal support frame.

[0007] As an optional solution of this application, the sidewall of the elastic metal strip is provided with a plurality of mounting blocks, and the end face of the mounting block is provided with mounting holes. The mounting block is embedded in the groove of the first metal screen or the second metal screen, and the bolt is inserted into the mounting hole to fix the first metal screen or the second metal screen on the elastic metal strip. As an optional solution of this application, the first metal screen or the second metal screen is spiral-shaped. Both the first metal screen and the second metal screen include an elastic frame and a screening mesh. The screening mesh is welded and fixed on the elastic frame. The elastic frame is adapted to the elastic metal strip and the mounting block. Anti-slip rubber strips are provided at the connection between the elastic frame and the elastic metal strip and the mounting block. As an optional solution of this application, the mating protrusion, the connecting flange and the side ring are designed as an integral part, and the cross-section of the side ring and the connecting flange is designed in an "L" shape. As an optional solution of this application, a plurality of the connection holes are distributed in a ring on the connection flange, and an anti-slip sealing ring is provided at the connection between the first elastic metal support frame and the second elastic metal support frame. As an optional solution in this application, the two connecting flanges are connected by a screw, and the length is limited by the screw. The length of the elastic metal strip is adjusted by the distance between the two connecting flanges. As an optional solution in this application, the elastic metal strip has multiple mounting blocks arranged in an alternating pattern, and the elastic metal strip is compressed and stored through two connecting flanges.

[0008] Compared with the prior art, the present invention has the following beneficial effects: The design of the flexible metal support frame, particularly the construction of the flexible metal strips and lateral rings, and the mounting chambers formed between them, provides support for the metal screen. This support structure effectively resists the vibrations and impacts generated during the screening process, thereby extending the screen's service life and improving its stability.

[0009] The metal screen can be easily fixed to the flexible metal strip thanks to the design of the mounting blocks and holes, and can also be quickly disassembled by removing the bolts. This design makes screen replacement and maintenance easier, improving work efficiency.

[0010] The length of the flexible metal strip can be adjusted by changing the distance between the connecting flanges, allowing users to adjust the screen tension as needed. This design ensures optimal screening performance during the screening process while preventing screen damage or reduced screening efficiency due to excessive or insufficient tension.

[0011] The spiral metal screen design and the way the screen is fixed to the elastic frame allow the screen to better capture and separate materials during the screening process. Furthermore, by adjusting the screen tension and angle, the screening effect can be further optimized, improving screening efficiency. Attached Figure Description

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] like Figure 1 - Figure 5As shown, an improved combined metal screen includes two identical support frames: a first elastic metal support frame 1 and a second elastic metal support frame 3. These two support frames, the first elastic metal support frame 1 and the second elastic metal support frame 3, have completely identical constructions. Specifically, the first elastic metal support frame 1 consists of lateral rings 11 and elastic metal strips 14, with lateral rings 11 fixed to both ends of the elastic metal strips 14. Notches 10 are designed on the lateral rings 11, and mating protrusions 18 are provided at these notches 10. Two mating protrusions 18 are fixed together by fasteners 19. Furthermore, a connecting flange 12 is installed at the outer end of the lateral rings 11, and multiple connecting holes 13 are provided on the end face of the connecting flange 12. The first elastic metal support frame 1 and the second elastic metal support frame 3 can be assembled through the cooperation of the connecting flange 12, the connecting holes 13, and bolts. An installation chamber 17 is formed between the elastic metal strip 14 and the lateral ring 11. A first metal screen 2 is installed in the installation chamber 17 of the first elastic metal support frame 1, while a second metal screen 4 is installed in the installation chamber 17 of the second elastic metal support frame 3. Multiple installation blocks 15 are designed on the side wall of the elastic metal strip 14, and installation holes 16 are formed on the end faces of these installation blocks 15. These installation blocks 15 can be embedded into pre-drilled grooves in the first metal screen 2 or the second metal screen 4. By inserting bolts into the installation holes 16, the first metal screen 2 or the second metal screen 4 can be firmly fixed to the elastic metal strip 14. The first metal screen 2 or the second metal screen 4 is designed in a spiral shape, and both include an elastic frame and a screening screen. The screening screen is fixed to the elastic frame by welding. The elastic frame is compatible with the elastic metal strip 14 and the mounting block 15. To increase the friction at the connection, anti-slip rubber strips are also designed at the connection between the elastic frame and the elastic metal strip 14 and the mounting block 15. The mating protrusion 18, the connecting flange 12, and the side ring 11 are designed as a single unit. The cross-section of the side ring 11 and the connecting flange 12 presents an "L" shape. Multiple connecting holes 13 are distributed in a ring on the connecting flange 12. In order to ensure the tightness of the connection, an anti-slip sealing ring is also provided at the connection between the first elastic metal support frame 1 and the second elastic metal support frame 3. The two connecting flanges 12 are connected by a screw, and the length is limited by the screw, so the length of the elastic metal strip 14 can be adjusted by the distance between the two connecting flanges 12; The multiple mounting blocks 15 on the elastic metal strip 14 are staggered, allowing the elastic metal strip 14 to be retracted by the compression of the two connecting flanges 12. This design not only improves the stability and durability of the screen but also makes the installation and disassembly of the screen more convenient and quick, increasing work efficiency. Furthermore, this design allows users to adjust the tension of the screen according to actual needs, thereby achieving optimal screening results.

[0016] Install the first metal screen 2 into the mounting chamber 17 of the first elastic metal support frame 1. Install the second metal screen 4 into the mounting chamber 17 of the second elastic metal support frame 3. Align the groove of the first metal screen 2 with the mounting block 15 of the first elastic metal support frame 1. Align the groove of the second metal screen 4 with the mounting block 15 of the second elastic metal support frame 3. Securely fix the metal screens to the elastic metal strip 14 by inserting bolts into the mounting holes 16. Align the mating protrusions 18 of the first elastic metal support frame 1 and the second elastic metal support frame 3. Secure the two mating protrusions 18 together using fasteners 19. Ensure that the outer end of the lateral ring 11 is fitted with a connecting flange 12.

[0017] Connect the two connecting flanges 12 together using screws. Use screws to limit the length and adjust the length of the elastic metal strip 14. Install anti-slip sealing rings at the connection between the first elastic metal support frame 1 and the second elastic metal support frame 3 to ensure a tight connection.

[0018] Place the assembled modular metal screen on the equipment or location where screening is required. Ensure the screen is correctly positioned and securely fixed. Adjust the tension of the elastic metal strip 14 by adjusting the length of the screws between the connecting flanges 12, according to the actual screening needs. Ensure the screen tension is moderate for optimal screening results. Start the screening equipment and allow the material to pass through the metal screen. Adjust the screening speed and screen angle (if necessary) according to the material characteristics and screening requirements. Regularly check the integrity and tension of the screen, making necessary adjustments and replacements. Clean any accumulated material on the screen to ensure screening efficiency. After completing the screening operation, disassemble the screen and support frame in the reverse order of assembly. Clean the components and store them in a dry, well-ventilated place for future use.
