Description

Technical Field

[0001] This utility model belongs to the technical field of linear screen equipment, specifically relating to a linear screen combination screen plate for screening coke. Background Technology

[0002] In the coke screening process, coke needs to be classified according to particle size to obtain metallurgical coke and coke dust. Screening equipment is used to screen the coke. Among the existing screening equipment, the commonly used screen plate types include round hole screen plates, square hole screen plates, bar screens, horseshoe-shaped screen plates, and teardrop-shaped screen plates.

[0003] In practical applications, round-hole screens have a small screening area, square-hole screens are prone to clogging, bar screens have unsatisfactory screening effects, horseshoe-shaped screens are prone to excessive metallurgical coke content in coke dust, and teardrop-shaped screens, when the screen holes are small, are prone to excessive coke dust content in metallurgical coke, and the coke's moisture content easily clogs the screen holes. Therefore, in practical applications, a combination of horseshoe-shaped screens and teardrop-shaped screens is used.

[0004] Therefore, a linear screen combination screen plate for screening coke is proposed. Utility Model Content

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1, such as Figure 1-2 As shown, a linear screen assembly for screening coke includes a vibrating screen 1. The vibrating screen 1 promotes material screening through vibration, effectively separating coke of different particle sizes. It has high screening efficiency, can quickly classify materials, and is highly adaptable to processing various materials. The vibrating screen 1 is equipped with vibrating screen holes 2, which allow materials of suitable particle size to pass through, while larger particles remain on the surface. By rationally designing the size and distribution of the vibrating screen holes 2, the screening effect and efficiency can be improved, material blockage can be reduced, and the screening accuracy can be increased.

[0020] The vibrating screen 1 is configured with 9 rows of screen plates. This 9-row design allows for multi-stage screening, ensuring that materials can be screened at different particle sizes to achieve optimal grading. Each row can be configured with a suitable screen plate type based on the different characteristics of the material. Each row has 3 screen plates arranged side-by-side. The 3 screen plates increase the screening area, thereby improving the material's contact and screening opportunities within that row. The side-by-side configuration significantly enhances the overall processing capacity, ensuring that the material is fully screened during passage while reducing blockages caused by material aggregation.

[0021] The sieve plate includes a horseshoe sieve plate 5 and a teardrop sieve plate 3. The horseshoe sieve plate 5, with its specially shaped hole design, provides a screening effect different from traditional flat holes, effectively screening coke within a specific particle size range. The teardrop sieve plate 3 has a larger screening area and a specific hole shape, effectively improving screening efficiency. The horseshoe sieve plate 5 is provided with horseshoe-shaped holes 6, which effectively screen out coke of suitable size. The teardrop sieve plate 3 is provided with teardrop-shaped holes 4, which allow materials that meet the particle size requirements to pass through.

[0022] The specific design of the aforementioned key components will be discussed in detail below:

[0023] The vibrating screen 1 is tilted at an angle of 10°. This tilt angle refers to the angle of inclination of the screen plate relative to the horizontal plane. Setting it to 10° allows the coke to flow at an appropriate angle on the screen plate, thereby enhancing the gravity-fall effect of the material, suitable for gravity-driven screening. A smaller tilt angle helps reduce the time the material stays on the screen plate, ensuring faster passage, improving screening efficiency, and reducing problems caused by clogging. The vibrating screen 1 has an amplitude of 9mm. The amplitude is the maximum distance the vibrating screen 1 moves up and down during vibration. By setting an appropriate amplitude, it ensures that the material moves fully on the screen plate and avoids sedimentation and jamming. The 9mm amplitude is moderate, enhancing the material's ability to pass through the screen openings and improving screening efficiency.

[0024] The horseshoe-shaped screen 6 has a length of 31mm and a width of 18mm. It effectively filters out larger particles, especially those from metallurgical coke. The horseshoe shape ensures that particles pass through easily without getting stuck during screening. The larger horseshoe-shaped screen 6 improves screening efficiency, making it particularly suitable for separating coke dust and ensuring compliance with metallurgical coke particle size requirements. The teardrop-shaped screen 4 has a length of 40mm and a maximum width of 16mm. Its teardrop shape effectively improves the screening capacity for small particles, especially for the efficient separation of coke dust and fine particles, ensuring that fine particles pass through quickly and improving the accuracy and quality of overall coke screening.

[0025] The first row of screen plates in the vibrating screen 1 is configured as horseshoe screen plates 5. Placing the horseshoe screen plates 5 at the top row allows for preliminary screening of the material, prioritizing the removal of large coke particles, achieving a better initial classification effect, and improving the screening efficiency of subsequent rows. The middle rows of the second, third, and fourth rows of screen plates in the vibrating screen 1 are also configured as horseshoe screen plates 5 to further screen medium-sized particles, ensuring precise control over coke particle size adjustment and enhancing the separation effect between metallurgical coke and coke dust. The remaining screen plates are water droplet screen plates 3, which screen smaller particles, ensuring that fine particles can pass through effectively during the screening process.

[0026] The material flow through the screen plate is relatively large, and the impact force is high. Therefore, the screen plate at the feed inlet must be impact-resistant. Due to the large material flow and high material speed, the first row of screen plates should use horseshoe-shaped screen plates 5, which offer good screening performance. Based on observation of the material flow distribution on the screen plates, the middle row, rows 2-4, is set with horseshoe-shaped screen plates 5. The material speed generally decreases after passing through the 2nd-3rd rows, so the other screen plates of the vibrating screen 1 can use water droplet screen plates 3 to ensure screening efficiency.

[0027] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
