Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, and in particular to a screening equipment with a micro-powered screening structure. Background Technology

[0002] In the production processes of coking plants and steel mills, efficient material screening is crucial. The materials processed in these plants, such as coke, iron ore, and various auxiliary materials, are complex in nature, vary greatly in particle size, and often possess sticky or moist characteristics. Traditional screening equipment has particularly significant drawbacks when used in these two industries.

[0003] Most traditional screening equipment uses a single screen plate structure, which is simply unable to achieve multi-level fine screening when faced with the diverse materials in coking plants and steel plants. Taking coke screening as an example, a single screen plate is difficult to accurately separate coke of different particle sizes, resulting in inconsistent coke quality in subsequent coking and ironmaking processes, which affects product quality and production efficiency.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] like Figures 1 to 6 As shown, this utility model discloses a screening device with a micro-powered screening structure, used for material screening. The screening device includes a frame 10, an upper screening module 20, and a lower screening module 30. The upper screening module 20 and the lower screening module 30 are arranged vertically aligned and installed within the frame 10. The upper screening module 20 and the lower screening module 30 respectively perform preliminary screening and enhanced screening of materials, achieving multi-level screening and meeting the industry's screening needs.

[0036] Please see Figure 4 The frame 10 has an inclined screening chamber 11 on its inner side. A feed inlet 12, connected to the screening chamber 11, is located diagonally above the frame 10. A first discharge outlet 13, also connected to the screening chamber 11, is located diagonally below the frame 10. A second discharge outlet 14, connected to the screening chamber 11, is located directly below the frame 10. During operation, the material to be screened enters the screening chamber 11 through the feed inlet 12 and passes sequentially through the upper screening module 20 and the lower screening module 30. Different materials are discharged from the first discharge outlet 13 and the second discharge outlet 14, effectively classifying the materials. Additionally, the frame 10 is equipped with a dust removal hole 15 for connecting to an air duct to extract dust generated during the screening process, protecting the environment. A ladder 16 is also provided on the side of the frame 10 for easy access by operators.

[0037] Specifically, such as Figure 1 and Figure 2 As shown, the feed inlet 12 is connected to a feed pipe 40. The bottom of the inner side of the feed pipe 40 is provided with a guide bottom surface 41. The guide bottom surface 41 has an arc-shaped structure and the bottom of the guide bottom surface 41 is connected to the upper screening module 20. When the material to be screened is poured into the feed pipe 40, since the bottom of the guide bottom surface 41 is connected to the upper screening module 20, it can be ensured that the material to be screened enters the upper screening module 20 first, and will not directly enter the lower screening module 30. This ensures that the material can pass through the upper screening module 20 and the lower screening module 30 in sequence for secondary screening, thus ensuring the screening quality.

[0038] Specifically, the first discharge port 13 is equipped with a discharge pipe 50, which has a first discharge port 51 and a second discharge port 52 arranged vertically side by side. The first discharge port 51 corresponds to the upper screening module 20, and the second discharge port 52 corresponds to the lower screening module 30. In actual application, materials that cannot pass through the first screening module are discharged through the first discharge port 51, materials that pass through the first screening module but cannot pass through the second screening module are discharged through the second discharge port 52, and materials that pass through the second screening module are discharged through the second discharge port 14. This structure further achieves material grading and ensures screening quality.

[0039] Please see Figure 4 and Figure 5The upper screening module 20 includes multiple upper screening plates 21 connected at the ends and fixed within the screening chamber 11. It should be noted that there is a drop between adjacent upper screening plates 21 to prevent material accumulation. Furthermore, each upper screening plate 21 includes a first connecting rod 22 and multiple first screen bars 23 equidistantly arranged on the first connecting rod 22, with gaps between adjacent first screen bars 23 forming a first gap. When material falls and contacts the first screen bars 23, some material can pass through the first gap, while some cannot, thus achieving the first screening. The top surface of each first screen bar 23 has an arc-shaped structure, which facilitates material sliding; the first connecting rod 22 is installed at the center of the bottom of the first screen bar 23.

[0040] Please see Figures 4 to 6 The lower screening module 30 includes multiple lower screening plates 31, a transmission frame 32, and a vibration module 33. The transmission frame 32 is disposed within the screening chamber 11. The multiple lower screening plates 31 are connected end-to-end and assembled on the transmission frame 32, with a height difference between adjacent lower screening plates 31, effectively improving the screening effect. The lower screening plates 31 are positioned below the upper screening plate 21. The vibration module 33 is driven and connected to the transmission frame 32. In this embodiment, the vibration module 33 uses a vibration motor. The vibration motor generates vibration, causing the transmission frame 32 to vibrate, which in turn drives the lower screening plates 31 to vibrate, enhancing the screening quality while preventing material accumulation and adhesion.

[0041] Specifically, the transmission frame 32 includes a supporting crossbeam 321, two connecting side plates 322, and a connecting beam 323. The supporting crossbeam 321 is horizontally arranged in the screening chamber 11, with both ends extending out of the frame 10. The connecting beam 323 is located on the side of the frame 10 and connected to the supporting crossbeam 321. The two connecting side plates 322 are arranged opposite each other on the upper end of the supporting crossbeam 321, and the lower screening plate 31 is assembled between the connecting side plates 322. The vibration module 33 is fixed to the connecting beam 323. The supporting crossbeam 321, the connecting side plates 322, and the connecting beam 323 are fixed together by bolts and welding, making the transmission frame 32 structurally stable and able to effectively transmit vibration. In addition, the lower screening plate 31 is arranged between the two connecting side plates 322, ensuring the contact area between the material and the lower screening plate 31, thus ensuring the screening quality. Furthermore, buffer modules 34 are provided on both sides of the frame 10. Each buffer module 34 includes a support column 341, connecting brackets 342 on both sides of the support column 341, and connecting columns 343 fixed to the upper ends of the connecting brackets 342. A buffer piston assembly 344 is provided on the connecting column 343, and the top of the connecting column 343 is connected to the connecting beam 323. A fixed bracket 345 is provided on the top of the support column 341 and is fixedly connected to the side of the frame 10. The buffer piston assembly 344 provides a flexible connection structure for the transmission frame 32, allowing the transmission components to have floating space, effectively transmitting vibration, and extending the service life of the structure.

[0042] Specifically, the lower screening plate 31 includes a second connecting rod 311 and a plurality of second screening bars 312 equidistantly arranged on the second connecting rod 311, with a second gap formed between adjacent second screening bars 312; wherein the width of the second gap is smaller than the width of the first gap, which conforms to the screening logic. In addition, the second screening bars 312 are cylindrical, and one end of the second screening bar 312 is fixed to the side of the second connecting rod 311.

[0043] Compared to existing technologies, the screening equipment with a micro-powered screen structure involved in this utility model, through the design of the inclined screening chamber 11, allows materials to flow naturally and smoothly within the chamber by gravity. Combined with the preliminary screening of the upper fixed screening plate and the enhanced screening of the lower vibrating screening plate, it achieves efficient and precise multi-level screening, meeting the stringent screening accuracy requirements of various industries. The transmission frame 32 ensures structural stability, allowing the vibration module 33 to effectively transmit vibration. The buffer modules on both sides can effectively reduce vibration impact, ensuring stable operation and long service life of the equipment. The drop between adjacent screening plates promotes continuous material flow and avoids accumulation. The screen bars with different gaps are set in accordance with the material screening logic, which can effectively classify and process materials. The inclined upper feed port 12, combined with the arc-shaped guide bottom surface 41, allows materials to enter evenly. The dual-outlet design of the first discharge port 13 and the second discharge port 14 at different positions at the inclined lower and directly lower positions facilitates the precise collection of materials at different screening levels, greatly improving the convenience and efficiency of the overall production process.

[0044] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
