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.

[0032] like Figures 1 to 5 As shown, this utility model discloses a screening device for coking, applicable to coking plants and steel mills. Its function is to screen materials such as coal and coke. The screening device includes a feeding mechanism 100 and a screening mechanism 200. The feeding mechanism 100 is used to transport the material to be screened to the screening mechanism 200, and the screening mechanism 200 is used to screen the material to meet subsequent production needs.

[0033] Please see Figures 1 to 4 The feeding mechanism 100 includes a feeding hopper 10, which has an L-shaped feeding trough 11 inside. The feeding trough 11 has a material conveying module 20 and a feeding control module 30 inside. The material conveying module 20 is used to convey materials into the feeding hopper 10, and the feeding control module 30 is used to control the amount of material fed. Meanwhile, the side of the feeding hopper 10 is provided with a horizontally extending mounting hole 12 and an elongated hole 13, wherein the mounting hole 12 is used to connect with the material conveying module 20, and the elongated hole 13 is used to connect with the feeding control module 30.

[0034] Specifically, the material conveying module 20 includes a drive shaft 21 and a conveyor belt 22 sleeved on the drive shaft 21. Both ends of the drive shaft 21 are connected to the mounting holes 12, and the motor drives the conveyor belt 22 to rotate. In practical applications, the other end of the conveyor belt 22 is connected to the material conveying line, and the material enters the feed hopper 10 through the conveyor belt 22.

[0035] Specifically, the feeding control module 30 includes a baffle plate 31 and a connecting shaft 32. The baffle plate 31 is located at one end of the conveyor belt 22, and the connecting shaft 32 is located on the side of the baffle plate 31 away from the conveyor belt 22. The connecting shaft 32 is slidably connected within the elongated hole 13, and the connecting shaft 32 can slide along the elongated hole 13 to adjust the position of the baffle plate 31. Figure 3 As shown, when the connecting shaft 32 slides along the elongated hole 13, the distance between the baffle plate 31 and the conveyor belt 22 changes accordingly, which can be understood as changing the amount of material passing through, thereby regulating the feed rate. At the same time, the baffle plate 31 can rotate around the axis of the connecting shaft 32. When feeding, the material contacts the baffle plate 31, and the baffle plate 31 swings to a certain extent to ensure the smooth passage of the material.

[0036] Furthermore, the baffle plate 31 has a guiding surface 311 on the side facing the conveyor belt 22. The guiding surface 311 has an arc-shaped structure. During feeding, the guiding surface 311 guides the material, controls the feeding path of the material, increases the feeding speed, and thus ensures the smooth progress of the subsequent screening process. In addition, the baffle plate 31 also includes limiting parts 312 on both sides of the guiding surface 311. The limiting parts 312 can prevent the material from overflowing from both sides and further restrict the feeding path of the material.

[0037] Please see Figures 1 to 5 The screening mechanism 200 includes a frame 40 connected to the lower end of the feed hopper 10 and multiple screening plates 50 disposed within the frame 40. The frame 40 contains a screening trough 41 and a discharge trough 42 that are interconnected. The screening trough 41 includes a feed inlet 41a and a discharge outlet 41b. The screening trough 41 is angled downwards, and the discharge trough 42 is located at the bottom of the screening trough 41. The multiple screening plates 50 are connected end-to-end and are positioned at the junction of the screening trough 41 and the discharge trough 42 to separate them. In actual operation, such as... Figure 3 As shown, the material to be screened enters from the feed inlet 41a of the screening trough 41, and then the material comes into contact with the screening plate 50 and is screened. The material that can pass through the screening plate 50 is discharged from the discharge trough 42, and the material that cannot pass through the screening plate 50 is discharged from the discharge outlet 41b; thus, screening is achieved.

[0038] Specifically, an arc-shaped buffer section 43 is provided at the feed inlet 41a, and an elastic material 44 is laid on the inner side of the buffer section 43 to cushion the material and ensure smooth screening. The top of the frame 40 is provided with an exhaust port 45 connected to the screening trough 41, which is connected to an exhaust pipe to remove dust, prevent dust accumulation, and improve the environment. In addition, the top of the frame 40 is provided with an observation window 46 for real-time monitoring of equipment operation. The frame 40 also has transversely arranged support beams 47 inside to support the frame 40, improve the internal structural strength, and prevent structural loosening due to vibration during the screening process.

[0039] Specifically, it also includes a connecting frame 300 and a slide rail 400, wherein the connecting frame 300 is fixedly connected to the frame 40 and slidably connected to the slide rail 400; and a roller 310 cooperating with the slide rail 400 is provided at the bottom of the connecting frame 300. The connecting frame 300 can slide along the slide rail 400 to adjust the position of the frame 40, thereby meeting the layout requirements of the production line. In addition, the connecting frame 400 is also connected to a ladder 320, which facilitates workers to climb up for monitoring and other operations. In this embodiment, a chute 500 fixed on the connecting frame 300 is also provided for material conveying.

[0040] Specifically, the screening plate 50 includes a connecting beam 51 and multiple screen bars 52 fixed on the connecting beam 51. A passage gap is left between the screen bars 52 to ensure normal material screening. The upper end face of each screen bar 52 has an arc-shaped structure; during screening, the material collides with the upper end face of the screen bar 52, further improving the screening quality.

[0041] The working principle of the screening equipment for coking involved in this utility model is as follows:

[0042] The material to be screened enters the feed hopper 10 through the material conveying module 20 and then enters the frame 40 through the feed control module 30. The material enters the screening trough 41 and comes into contact with the screening plate 50. Some of the material passes through the screening plate 50 and enters the discharge trough 42, while the other part of the material cannot pass through the screening plate 50 and is discharged from the discharge port 41b, thereby achieving the screening of the material.

[0043] Compared with the prior art, the screening equipment for coking involved in this utility model is equipped with a feeding mechanism 100 and a screening mechanism 200. The material conveying module 20 and the feeding control module 30 in the feeding mechanism 100 work together to accurately control the material feed amount and ensure the stability and efficiency of the screening process. At the same time, the material conveying module 20 is connected to the external conveying line to meet the layout requirements of the screening production line. The screening mechanism 200 has a downward-sloping screening trough 41 and a screening plate 50. The screening plate 50 is used to screen materials, which can effectively improve screening efficiency and quality and meet the production needs of coking plants and steel plants.

[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.
