Description

Technical Field

[0001] This invention relates to the field of coking technology for large-volume foundry coke, specifically to a screening device for high-strength foundry coke. Background Technology

[0002] After the petroleum coke (raw coke) and the raw coal are crushed to different particle sizes, the petroleum is heated to a certain temperature, and a certain proportion of petroleum coke is added to the raw coal according to the particle size distribution requirements and mixed evenly. The mixture is then loaded into the carbonization chamber of a heat recovery coke oven and pyrolyzed according to the predetermined dry distillation temperature and heating rate. After a series of processing steps, the coke is finally quenched and screened to produce high thermal stability foundry coke products of different particle sizes. However, currently, when screening foundry coke, it is necessary to first remove the foundry coke from the processing equipment, and then screen the foundry coke multiple times. Each screening requires changing the screen with a different mesh size. The operation process is cumbersome and requires the intervention of multiple power equipment. The entire screening process is not only complicated, but also increases the processing cost of enterprises.

[0003] Therefore, we propose a screening device for high-strength foundry coke. Summary of the Invention

[0004] The purpose of this invention is to provide a screening device for high-strength foundry coke to solve the problems mentioned in the background art.

Springs are fixedly connected to the top of the pads. The tops of the four springs are fixedly connected to the screens. The screens are slidably connected to the inner wall of the screen frame. A rotating rod is rotatably connected to the inner wall of the screen frame. A cam is fixedly connected to one end of the rotating rod. A gear is fixedly connected to one end of the rotating rod extending out of the screen frame. Circumventing grooves are equidistantly provided on one side of the connecting frame. A rack is fixedly connected to the inner wall of the circumventing groove, and the rack meshes with the gear.

[0008] Preferably, the conveying device includes: a pallet, a guide plate, and a connecting shaft. The pallet is fixedly connected to the top of the base plate, and the guide plate is fixedly connected to the top of the pallet. A connecting shaft is rotatably connected between one side of the pallet and the conveyor belt. One end of the connecting shaft extends out of the conveyor belt and is fixedly connected to a first pulley. A second pulley is rotatably connected to one side of the support.

[0013] Compared with the prior art, the beneficial effects of the present invention are: In use, this invention utilizes a motor to drive a conveyor belt, which in turn rotates the connecting shaft and crankshaft via a first and second pulley. A pull rod then drives the base and three screen frames to reciprocate up and down. Combined with the working of the connecting frame, the first connecting plate, and the second connecting plate, the foundry coke rolls on the screen mesh. Four springs and cams further agitate the screen mesh, accelerating the screening process. The screened coke falls into the screen frame, while unscreened coke is conveyed through the top of the connecting frame, the first connecting plate, and the second connecting plate to the conveyor belt for collection and subsequent processing. This design reduces the number of multi-stage screening procedures and minimizes equipment intervention, thereby lowering production costs for enterprises. Attached Figure Description

The three screen frames 10 are designed in a stepped manner, and a telescopic discharge pipe 13 is fixedly connected to one end of each of the three screen frames 10. The tops of the first connecting plate 7, the second connecting plate 8, and the connecting frame 6 are designed to be inclined.

[0018] Please see Figure 4-6As shown, the filtering device 11 includes: a pad 111, springs 112, and screens 113. The pads 111 are symmetrically fixedly connected inside the screen frame 10. Springs 112 are fixedly connected to the top of the pads 111. Screens 113 are fixedly connected to the top of the four springs 112. The screens 113 are slidably connected to the inner wall of the screen frame 10. A rotating rod 114 is rotatably connected to the inner wall of the screen frame 10. A cam 115 is fixedly connected to one end of the rotating rod 114. A gear 116 is fixedly connected to one end of the rotating rod 114 that extends out of the screen frame 10. A clearance groove 117 is equidistantly provided on one side of the connecting frame 6. A rack 118 is fixedly connected to the inner wall of the clearance groove 117. The rack 118 meshes with the gear 116. The three screens 113 are all inclined. The mesh size of the three screens 113 is arranged from small to large.

[0019] Please see Figure 1-6 As shown, the conveying device 12 includes a pallet 121, a guide plate 122, and a connecting shaft 123. The pallet 121 is fixedly connected to the top of the base plate 1, and the guide plate 122 is fixedly connected to the top of the pallet 121. The connecting shaft 123 is rotatably connected between one side of the pallet 121 and the conveyor belt 3. One end of the connecting shaft 123 extends out of the conveyor belt 3 and is fixedly connected to a first pulley 124. A second pulley 125 is rotatably connected to one side of the bracket 2. The first pulley 124 and the second pulley 125 are connected by belt drive. A crankshaft 126 is fixedly connected to one end of the connecting shaft 123. A pull rod 127 is rotatably connected to one end of the crankshaft 126. The pull rod 127 is rotatably connected to the bottom end of the base 9.

[0020] Working principle: In use, the processed casting coke is first guided by the guide plate 122, causing it to fall onto the first screen 113. At this point, the motor 4 is started, driving the conveyor belt 3. The rotation of the first pulley 124 and the second pulley 125 drives the connecting shaft 123 to rotate, simultaneously causing the crankshaft 126 to rotate as well. This, combined with the pull rod 127, causes the base 9 and the three screen frames 10 of different heights to move up and down together. Simultaneously, the gear 116 on the rotating rod 114 inside the screen frame 10 engages with the rack 118 in the clearance groove 117, causing the rotating rod 114 to rotate with the cam 115. This causes one end of the cam 115 to continuously strike the bottom of the screen 113, further interacting with the four... A spring 112 causes the screen 113 to move up and down repeatedly under the drive of the cam 115, thereby accelerating the filtration speed. When the three screen frames 10 move to a certain height, the gear 116 and the rack 118 are no longer meshed. At this time, the screen 113 is flush with the screen frame 10, and the unfiltered casting coke is pushed by the screen frame 10 to the side close to the first connecting plate 7, the second connecting plate 8, or the connecting frame 6. When the base 9 and the three screen frames 10 move to the highest point, the screen frame 10 is much higher than the first connecting plate 7, the second connecting plate 8, or the connecting frame 6. At this time, the casting coke will be conveyed to the side of the next screen frame 10. When the screen frame 10 descends, it falls on the screen 113 of the screen frame 10 until the completely unfiltered casting coke is conveyed to the conveyor belt 3 for collection.
